Randomised trial of impact of model of integrated care and case management for older people living in the community

Objective: To evaluate the impact of a programme of integrated social and medical care among frail elderly people living in the community. Design: Randomised study with 1 year follow up. Setting: Town in northern Italy (Rovereto). Subjects: 200 older people already receiving conventional community care services. Intervention: Random allocation to an intervention group receiving integrated social and medical care and case management or to a control group receiving conventional care. Main outcome measures: Admission to an institution, use and costs of health services, variations in functional status. Results: Survival analysis showed that admission to hospital or nursing home in the intervention group occurred later and was less common than in controls (hazard ratio 0.69; 95% confidence interval 0.53 to 0.91). Health services were used to the same extent, but control subjects received more frequent home visits by general practitioners. In the intervention group the estimated financial savings were in the order of £1125 ($1800) per year of follow up. The intervention group had improved physical function (activities of daily living score improved by 5.1% v 13.0% loss in controls; P<0.001). Decline of cognitive status (measured by the short portable mental status questionnaire) was also reduced (3.8% v 9.4%; P<0.05). Conclusion: Integrated social and medical care with case management programmes may provide a cost effective approach to reduce admission to institutions and functional decline in older people living in the community.

Key messages

• Responsibility for management of care of elderly people living in the community is poorly defined
• Integration of medical and social services together with care management programmes would improve such care in the community
• In a comparison of this option with a traditional and fragmented model of community care the integrated care approach reduced admission to institutions and functional decline in frail elderly people living in the community and also reduced costs

     

Effect of preoperative abstinence on poor postoperative outcome in alcohol misusers: randomised controlled trial

ObjectiveTo evaluate the influence of preoperative abstinence on postoperative outcome in alcohol misusers with no symptoms who were drinking the equivalent of at least 60 g ethanol/day. DesignRandomised controlled trial.SettingCopenhagen, Denmark.Subjects42 alcoholic patients without liver disease admitted for elective colorectal surgery.InterventionsWithdrawal from alcohol consumption for 1 month before operation (disulfiram controlled) compared with continuous drinking.ResultsThe intervention group developed significantly fewer postoperative complications than the continuous drinkers (31% v 74%, P=0.02). Delayed type hypersensitivity responses were better in the intervention group before (37 mm² v 12 mm², P=0.04), but not after surgery (3 mm² v 3 mm²). Development of postoperative myocardial ischaemia (23% v 85%) and arrhythmias (33% v 86%) on the second postoperative day as well as nightly hypoxaemic episodes (4 v 18 on the second postoperative night) occurred significantly less often in the intervention group. Surgical stress responses were lower in the intervention group (P⩽0.05).ConclusionsOne month of preoperative abstinence reduces postoperative morbidity in alcohol abusers. The mechanism is probably reduced preclinical organ dysfunction and reduction of the exaggerated response to surgical stress.

Key messages

• Recent data have shown alcohol misusers to have a threefold increase in postoperative morbidity
• In misusers recovery from organ dysfunction induced by alcohol is seen after abstinence
• Abstinence from alcohol for 1 month before surgery reduces postoperative morbidity after colorectal surgery
• Mechanisms may involve reduced responses to surgical stress and improved cardiac and immune dysfunction
• Withdrawal from alcohol before an operation is recommended in alcohol abusers

     

Family Practices' Achievement of Diabetes Quality of Care Targets and Risk of Screen-Detected Diabetic Retinopathy

Background

We aimed to determine whether family practices'' achievement of diabetes quality of care targets is associated with diabetic retinal disease in registered patients.

Methods

Data for achievement of diabetes quality of care targets, including the proportion of patients with HbA1c≤7.5%, for 144 family practices in London UK, for the years 2004/5 to 2007/8, were linked to data from a population-based diabetes eye screening programme collected from September 2007 to February 2009. Analyses were adjusted for age, sex, duration and type of diabetes, unadjusted diabetes prevalence, ethnicity and deprivation category.

Results

Data were analysed for 24,458 participants with one or more eye screening results in the period. There were 9,332 (38%) with any diabetic retinopathy and 2,819 (11.5%) with sight threatening diabetic retinopathy (STDR), including 2,654 (10.9%) with maculopathy. Among participants registered at 13 family practices that were in the highest quartile for achievement of the HbA1c quality of care target for all four years of study, the relative odds of any diabetic retinopathy were 0.78 (0.69 to 0.88) P<0.001. For participants at 12 practices consistently in the lowest quartile of HbA1c achievement, the relative odds of any diabetic retinopathy were 1.16 (1.03 to 1.30), P = 0.015. In the highest achieving practices, the relative odds of maculopathy were 0.74 (0.62 to 0.89), P = 0.001 and STDR 0.77 (0.65 to 0.92), P = 0.004.

Conclusions

The risk of diabetic retinopathy might be lower at family practices that consistently achieve highly on diabetes quality of care targets for HbA1c.     

Multifaceted shared care intervention for late life depression in residential care: randomised controlled trial

ObjectiveTo evaluate the effectiveness of a population based, multifaceted shared care intervention for late life depression in residential care.DesignRandomised controlled trial, with control and intervention groups studied one after the other and blind follow up after 9.5 months.SettingPopulation of residential facility in Sydney living in self care units and hostels.Participants220 depressed residents aged ⩾65 without severe cognitive impairment.InterventionThe shared care intervention included: (a) multidisciplinary consultation and collaboration, (b) training of general practitioners and carers in detection and management of depression, and (c) depression related health education and activity programmes for residents. The control group received routine care.ResultsIntention to treat analysis was used. There was significantly more movement to “less depressed” levels of depression at follow up in the intervention than control group (Mantel-Haenszel stratification test, P=0.0125). Multiple linear regression analysis found a significant intervention effect after controlling for possible confounders, with the intervention group showing an average improvement of 1.87 points on the geriatric depression scale compared with the control group (95% confidence interval 0.76 to 2.97, P=0.0011).ConclusionsThe outcome of depression among elderly people in residential care can be improved by multidisciplinary collaboration, by enhancing the clinical skills of general practitioners and care staff, and by providing depression related health education and activity programmes for residents.

Key messages

• Large numbers of depressed elderly people live in residential care but few receive appropriate management
• A population based, multifaceted shared care intervention for late life depression was more effective than routine care in improving depression outcome
• The outcome of late life depression can be improved by enhancing the clinical skills of general practitioners and care staff and by providing depression related health education and activity programmes for residents
• The intervention needs further refining and evaluation to improve its effectiveness and to determine how best to implement it in other residential care settings

     

Insecticide impregnated curtains to control domestic transmission of cutaneous leishmaniasis in Venezuela: cluster randomised trial

ObjectiveTo measure the impact on transmission of leishmaniasis of curtains impregnated with insecticide.DesignCluster randomised controlled trial: household interview survey, observational study of people''s behaviour, entomological study with light trap captures of sandflies inside houses.Setting14 urban sectors in Trujillo, Venezuela.Participants2913 inhabitants of 569 houses.InterventionSectors were paired according to their 12 month cumulative incidence of cutaneous leishmaniasis, one sector in each pair was randomly allocated to receive polyester curtains impregnated with lambdacyhalothrin (intervention group) while the other sector received curtains without insecticide or no curtains (control groups). After 12 months a follow up household survey was conducted.ResultsTransmission of cutaneous leishmaniasis occurred mainly in the domestic setting, with the incidence over 12 months of 4%. The mean number of sandflies per trap per night was 16. After follow up the 12 month incidence of cutaneous leishmaniasis was 0% in the intervention group and 8% in the six pairs in the control group that received unimpregnated curtains (mean difference 8, 95% confidence interval 4.22 to 11.78; P=0.001). There were significantly fewer sandflies in the intervention group (2 v 15, mean difference 13 sandflies per trap; 9 to 17; P<0.001).ConclusionCurtains impregnated with insecticide provide a high degree of protection against indoor transmission of cutaneous leishmaniasis.

What is already known on this topic

The transmission of cutaneous leishmaniasis is increasingly in urban and domestic settingsHouse spraying, space spraying, and insecticide treated material reduce the number of vectors

What this paper adds

Pyrethroid impregnated curtains can considerably reduce the incidence rate of cutaneous leishmaniasis in areas where indoor transmission is predominant     

Tight blood pressure control and risk of macrovascular and microvascular complications in type 2 diabetes: UKPDS 38

Objective: To determine whether tight control of blood pressure prevents macrovascular and microvascular complications in patients with type 2 diabetes.Design: Randomised controlled trial comparing tight control of blood pressure aiming at a blood pressure of <150/85 mm Hg (with the use of an angiotensin converting enzyme inhibitor captopril or a β blocker atenolol as main treatment) with less tight control aiming at a blood pressure of <180/105 mm Hg.Setting: 20 hospital based clinics in England, Scotland, and Northern Ireland.Subjects: 1148 hypertensive patients with type 2 diabetes (mean age 56, mean blood pressure at entry 160/94 mm Hg); 758 patients were allocated to tight control of blood pressure and 390 patients to less tight control with a median follow up of 8.4 years.Main outcome measures: Predefined clinical end points, fatal and non-fatal, related to diabetes, deaths related to diabetes, and all cause mortality. Surrogate measures of microvascular disease included urinary albumin excretion and retinal photography.Results: Mean blood pressure during follow up was significantly reduced in the group assigned tight blood pressure control (144/82 mm Hg) compared with the group assigned to less tight control (154/87 mm Hg) (P<0.0001). Reductions in risk in the group assigned to tight control compared with that assigned to less tight control were 24% in diabetes related end points (95% confidence interval 8% to 38%) (P=0.0046), 32% in deaths related to diabetes (6% to 51%) (P=0.019), 44% in strokes (11% to 65%) (P=0.013), and 37% in microvascular end points (11% to 56%) (P=0.0092), predominantly owing to a reduced risk of retinal photocoagulation. There was a non-significant reduction in all cause mortality. After nine years of follow up the group assigned to tight blood pressure control also had a 34% reduction in risk in the proportion of patients with deterioration of retinopathy by two steps (99% confidence interval 11% to 50%) (P=0.0004) and a 47% reduced risk (7% to 70%) (P=0.004) of deterioration in visual acuity by three lines of the early treatment of diabetic retinopathy study (ETDRS) chart. After nine years of follow up 29% of patients in the group assigned to tight control required three or more treatments to lower blood pressure to achieve target blood pressures.Conclusion: Tight blood pressure control in patients with hypertension and type 2 diabetes achieves a clinically important reduction in the risk of deaths related to diabetes, complications related to diabetes, progression of diabetic retinopathy, and deterioration in visual acuity.

Key messages

• This study showed that tight control of blood pressure based on captopril or atenolol as first agents and aiming for both a systolic blood pressure <150 mm Hg and diastolic pressure <85 mm Hg achieved a mean 144/82 mm Hg compared with 154/87 mm Hg in a control group
• 29% of patients in the tight control group required three or more hypotensive treatments
• Tight control of blood pressure reduced the risk of any non-fatal or fatal diabetic complications and of death related to diabetes; deterioration in visual acuity was also reduced
• Reducing blood pressure needs to have high priority in caring for patients with type 2 diabetes

     

How to evaluate and improve the quality and credibility of an outcomes database: validation and feedback study on the UK Cardiac Surgery Experience

ObjectivesTo assess the quality and completeness of a database of clinical outcomes after cardiac surgery and to determine whether a process of validation, monitoring, and feedback could improve the quality of the database.DesignStratified sampling of retrospective data followed by prospective re-sampling of database after intervention of monitoring, validation, and feedback.SettingTen tertiary care cardiac surgery centres in the United Kingdom.InterventionValidation of data derived from a stratified sample of case notes (recording of deaths cross checked with mortuary records), monitoring of completeness and accuracy of data entry, feedback to local data managers and lead surgeons.ResultsThe database was incomplete, with a mean (SE) of 24.96% (0.09%) of essential data elements missing, whereas only 1.18% (0.06%) were missing in the patient records (P<0.0001). Intervention was associated with (a) significantly less missing data (9.33% (0.08%) P<0.0001); (b) marginal improvement in reliability of data and mean (SE) overall centre reliability score (0.53 (0.15) v 0.44 (0.17)); and (c) improved accuracy of assigned Parsonnet risk scores (κ 0.84 v 0.70). Mortality scores (actual minus risk adjusted mortality) for all participating centres fell within two standard deviations of the mean score.ConclusionA short period of independent validation, monitoring, and feedback improved the quality of an outcomes database and improved the process of risk adjustment, but with substantial room for further improvement. Wider application of this approach should increase the credibility of similar databases before their public release.

What is already know in this topic

Release of healthcare outcomes into the public domain has altered referral patterns and has led to improvement in some centres and elimination of othersThe tacit assumption is that such outcomes data are accurate and can be relied on by the public and by healthcare providers to guide improvements

What this study adds

Sampling of a published national cardiac surgery database in England revealed it to be both incomplete and unreliable in its ability to yield accurate, risk adjusted outcomes dataAn independent short process of monitoring, validation, and feedback improved the quality of the databaseSuch databases probably require an ongoing process of monitoring in order to allow data of adequate quality to be generated for the purpose of improving healthcare outcomes     

Longevity of screenwriters who win an academy award: longitudinal study

ObjectiveTo determine whether the link between high success and longevity extends to academy award winning screenwriters.DesignRetrospective cohort analysis.ParticipantsAll screenwriters ever nominated for an academy award.ResultsA total of 850 writers were nominated; the median duration of follow up from birth was 68 years; and 428 writers died. On average, winners were more successful than nominees, as indicated by a 14% longer career (27.7 v 24.2, P=0.004), 34% more total films (23.2 v 17.3, P<0.001), 58% more four star films (4.8 v 3.1, P<0.001), and 62% more nominations (2.1 v 1.3, P<0.001). However, life expectancy was 3.6 years shorter for winners than for nominees (74.1 v 77.7 years, P=0.004), equivalent to a 37% relative increase in death rates (95% confidence interval 10 to 70). After adjustment for year of birth, sex, and other factors, a 35% relative increase in death rates was found (7% to 70%). Additional wins were associated with a 22% relative increase in death rates (3% to 44%). Additional nominations and additional other films in a career otherwise caused no significant increase in death rates.ConclusionThe link between occupational achievement and longevity is reversed in screenwriters who win academy awards. Doubt is cast on simple biological theories for the survival gradients found for other members of society.

What is already known on this topic

High achievement has been associated with decreased all cause mortality for people in many different occupationsSuch an association is compatible with behavioural and biological theories for the role of social determinants

What this study adds

Screenwriters nominated for an academy award show a paradoxical survival pattern, where greater success is associated with a large decrease in life expectancyThe paradox is not easily explained by talent, prestige, financial earnings, material conditions, reverse causality, measurement error, or simple demographicsIt might reflect the unusual lifestyles of writers, where success is not linked to exemplary conduct or control; this underscores the importance of behaviour     

Comparison of estimates and calculations of risk of coronary heart disease by doctors and nurses using different calculation tools in general practice: cross sectional study

ObjectiveTo assess the effect of using different risk calculation tools on how general practitioners and practice nurses evaluate the risk of coronary heart disease with clinical data routinely available in patients'' records.DesignSubjective estimates of the risk of coronary heart disease and results of four different methods of calculation of risk were compared with each other and a reference standard that had been calculated with the Framingham equation; calculations were based on a sample of patients'' records, randomly selected from groups at risk of coronary heart disease.SettingGeneral practices in central England.Participants18 general practitioners and 18 practice nurses.ResultsOnly a minority of patients'' records contained all of the risk factors required for the formal calculation of the risk of coronary heart disease (concentrations of high density lipoprotein (HDL) cholesterol were present in only 21%). Agreement of risk calculations with the reference standard was moderate (κ=0.33-0.65 for practice nurses and 0.33 to 0.65 for general practitioners, depending on calculation tool), showing a trend for underestimation of risk. Moderate agreement was seen between the risks calculated by general practitioners and practice nurses for the same patients (κ=0.47 to 0.58). The British charts gave the most sensitive results for risk of coronary heart disease (practice nurses 79%, general practitioners 80%), and it also gave the most specific results for practice nurses (100%), whereas the Sheffield table was the most specific method for general practitioners (89%).ConclusionsRoutine calculation of the risk of coronary heart disease in primary care is hampered by poor availability of data on risk factors. General practitioners and practice nurses are able to evaluate the risk of coronary heart disease with only moderate accuracy. Data about risk factors need to be collected systematically, to allow the use of the most appropriate calculation tools.

What is already known on this topic

Recent guidelines have recommended determining the risk of coronary heart disease for targeting patients at high risk for primary preventionEstimates of risk have been shown to be inaccurateGeneral practitioners and practice nurses can use risk calculation tools accurately when given patient data in the form of scenarios

What this study adds

Many patients do not have adequate information in their records to allow the risk of coronary heart disease to be calculatedWhen data about risk factors were available, risk calculations made by general practitioners and practice nurses were moderately accurate compared to a reference calculationWhen adequate information about risk factors is not available, subjective estimates are a reasonable alternative to calculating risk     

Cross sectional survey of effectiveness of lipid lowering drugs in reducing serum cholesterol concentration in patients in 17 general practices

ObjectiveTo compare the effectiveness of lipid lowering drugs in lowering serum cholesterol concentrations.DesignCross sectional study.Setting17 practices within 17 primary care groups in Trent region, United Kingdom.ParticipantsPatients aged 35 years or over taking lipid lowering drugs and with at least two serum cholesterol concentrations recorded on computer.Results1353 of 2469 (54.8%) patients receiving lipid lowering treatment had a last recorded serum cholesterol concentration of ⩽5 mmol/l. Significantly more patients taking statins achieved the target value for serum cholesterol (5 mmol/l) than those taking fibrates (1307 (57%) v 46 (26%); P<0.0001). Atorvastatin and simvastatin were the most effective drugs in achieving the target. Significant differences were found between lipid lowering drugs for the pretreatment serum cholesterol concentration, the most recent cholesterol concentration, and the associated percentage reduction. Atorvastatin and simvastatin achieved the greatest percentage reduction in serum cholesterol concentrations (30.1%, 95% confidence interval 28.8% to 31.4%, and 28.0%, 26.7% to 29.3%, respectively). Although the mean serum cholesterol concentrations in this unselected population tended to be higher than those in clinical trials, the percentage reduction was consistent with the trials.ConclusionThe ability of individual statins to lower serum cholesterol concentration varied, with atorvastatin and simvastatin being the most effective. The percentage reductions agreed with those of randomised controlled trials indicating likely benefits in unselected patients in primary care. As the initial serum cholesterol concentrations were higher than those in randomised controlled trials, target serum cholesterol values of ⩽5 mmol/l may be unrealistic even for patients taking the most efficacious drugs. Also, the higher initial levels could mean that the absolute reduction in cardiovascular risk in primary care patients is greater than thought.

What is already known on this topic

Statins in patients with coronary heart disease help reduce further cardiovascular events and improve survivalThis seems to be a class effect of statins, although there may be important differences in effectiveness between themLess than half of patients in the community who take lipid lowering drugs achieve target serum cholesterol values

What this study adds

Statins vary in their ability to lower serum cholesterol concentration, with atorvastatin and simvastatin achieving the best resultsThe percentage reductions agreed with those found in randomised controlled trialsSince the initial serum cholesterol concentrations were higher than in trials, absolute risk reductions in primary care patients may be greater than thoughtTarget values of ⩽5 mmol/l may be unrealistic even for patients on the most efficacious drugs, because the initial mean cholesterol values of primary care patients are higher than those of patients in trials     

Predictors of poor outcome and benefits from antibiotics in children with acute otitis media: pragmatic randomised trial

ObjectivesTo identify which children with acute otitis media are at risk of poor outcome and to assess benefit from antibiotics in these children.DesignSecondary analysis of randomised controlled trial cohort.SettingPrimary care.Participants315 children aged 6 months to 10 years.InterventionImmediate or delayed (taken after 72 hours if necessary) antibiotics.ResultsDistress by day three was more likely in children with high temperature (adjusted odds ratio 4.5, 95% confidence interval 2.3 to 9.0), vomiting (2.6,1.3 to 5.0), and cough (2.0, 1.1 to 3.8) on day one. Night disturbance by day three was more likely with high temperature 2.4 (1.2 to 4.8), vomiting (2.1,1.1 to 4.0), cough (2.3,1.3 to 4.2), and ear discharge (2.1, 1.2 to 3.9). Among the children with high temperature or vomiting, distress by day three was less likely with immediate antibiotics (32% for immediate v 53% for delayed, χ²=4.0; P=0.045, number needed to treat 5) as was night disturbance (26% v 59%, χ²=9.3; P=0.002; number needed to treat 3). In children without higher temperature or vomiting, immediate antibiotics made little difference to distress by day three (15% v 19%, χ²=0.74; P=0.39) or night disturbance (20% v 27%, χ²=1.6; P=0.20). Addition of cough did not significantly improve prediction of benefit.ConclusionIn children with otitis media but without fever and vomiting antibiotic treatment has little benefit and a poor outcome is unlikely.

What is already known on this topic

Most children with otitis media will not benefit symptomatically from immediate use of antibioticsIt is unclear which children are more likely to benefit from antibiotics and which features predict poor outcome

What this study adds

Children with high temperature or vomiting were more likely to be distressed or have night disturbance three days after seeing the doctorChildren with high temperature or vomiting were more likely to benefit from antibiotics, although it is still reasonable to wait 24-48 hours as many children will settle anywayChildren without high temperature or vomiting were unlikely to have poor outcome and unlikely to benefit from immediate antibiotics     

Twice daily versus four times daily insulin dose regimens for diabetes in pregnancy: randomised controlled trial

ObjectiveTo compare perinatal outcome and glycaemic control in two groups of pregnant diabetic patients receiving two insulin regimens.DesignRandomised controlled open label study.SettingUniversity affiliated hospital, Israel.Participants138 patients with gestational diabetes mellitus and 58 patients with pregestational diabetes mellitus received insulin four times daily, and 136 patients with gestational diabetes and 60 patients with pregestational diabetes received insulin twice daily.InterventionThree doses of regular insulin before meals and an intermediate insulin dose before bedtime (four times daily regimen), and a combination of regular and intermediate insulin in the morning and evening (twice daily regimen).ResultsMean daily insulin concentration before birth was higher in the women receiving insulin four times daily compared with twice daily: by 22 units (95% confidence interval 12 to 32) in patients with gestational diabetes and by 28 units (15 to 41) in patients with pregestational diabetes. Glycaemic control was better with the four times daily regimen than with the twice daily regimen: in patients with gestational diabetes mean blood glucose concentrations decreased by 0.19 mmol/l (0.13 to 0.25), HbA_1c by 0.3% (0.2% to 0.4%), and fructosamine by 41 μmol/l (37 to 45), and adequate glycaemic control (mean blood glucose concentration <5.8 mmol/l) was achieved in 17% (8% to 26%) more women; in patients with pregestational diabetes mean blood glucose concentration decreased by 0.44 mmol/l (0.28 to 0.60), HbA_1c by 0.5% (0.2% to 0.8%), and fructosamine by 51 μmol/l (45 to 57), and adequate glycaemic control was achieved in 31% (15% to 47%) more women. Maternal severe hypoglycaemic events, caesarean section, preterm birth, macrosomia, and low Apgar scores were similar in both dose groups. In women with gestational diabetes the four times daily regimen resulted in a lower rate of overall neonatal morbidity than the twice daily regimen (relative risk 0.59, 0.38 to 0.92), and the relative risk for hyperbilirubinaemia and hypoglycaemia was lower (0.51, 0.29 to 0.91 and 0.12, 0.02 to 0.97 respectively). The relative risk of hypoglycaemia in newborn infants to mothers with pregestational diabetes was 0.17 (0.04 to 0.74).ConclusionsGiving insulin four times rather than twice daily in pregnancy improved glycaemic control and perinatal outcome without further risking the mother.

Key messages

• Improving maternal glycaemic control during pregnancy is the key to better perinatal outcome
• In pregnant diabetic women insulin four times daily achieved better glycaemic control and lower rate of perinatal complications (hypoglycaemia, hyperbilirubinaemia) than insulin twice daily
• Better glycaemic control resulted from a larger total daily insulin dose
• The intensified regimen did not lead to higher rate of severe maternal hypoglycaemia

     

Prevalence of left ventricular systolic dysfunction and heart failure in high risk patients: community based epidemiological study

ObjectivesTo determine the prevalence of left ventricular systolic dysfunction, and of heart failure due to different causes, in patients with risk factors for these conditions.DesignEpidemiological study, including detailed clinical assessment, electrocardiography, and echocardiography.Setting16 English general practices, representative for socioeconomic status and practice type.Participants1062 patients (66% response rate) with previous myocardial infarction, angina, hypertension, or diabetes.ResultsDefinite systolic dysfunction (ejection fraction <40%) was found in 54/244 (22.1%, 95% confidence interval 17.1% to 27.9%) patients with previous myocardial infarction, 26/321 (8.1%, 5.4% to 11.6%) with angina, 7/388 (1.8%, 0.7% to 3.7%) with hypertension, and 12/208 (5.8%, 3.0% to 9.9%) with diabetes. In each group, approximately half of these patients had symptoms of dyspnoea, and therefore had heart failure. Overall rates of heart failure, defined as symptoms of dyspnoea plus objective evidence of cardiac dysfunction (systolic dysfunction, atrial fibrillation, or clinically significant valve disease) were 16.0% (11.6% to 21.2%) in patients with previous myocardial infarction, 8.4% (5.6% to 12.0%) in those with angina, 2.8% (1.4% to 5.0%) in those with hypertension, and 7.7% (4.5% to 12.2%) in those with diabetes.ConclusionMany people with ischaemic heart disease or diabetes have systolic dysfunction or heart failure. The data support the need for trials of targeted echocardiographic screening, in view of the major benefits of modern treatment. In contrast, patients with uncomplicated hypertension have similar rates to the general population.

What is already known on this topic

The prognosis and symptoms of patients with left ventricular systolic dysfunction and heart failure can be greatly improved by modern treatmentsMany patients with heart failure do not have an assessment of left ventricular function, resulting in undertreatment of the condition

What this study adds

Patients with a history of ischaemic heart disease (especially those with previous myocardial infarction) or diabetes commonly have left ventricular systolic dysfunctionThese patients would be candidates for a targeted echocardiographic screening programmeIn contrast, the yield from screening patients with uncomplicated hypertension would be low     

Limits of teacher delivered sex education: interim behavioural outcomes from randomised trial

ObjectiveTo determine whether a theoretically based sex education programme for adolescents (SHARE) delivered by teachers reduced unsafe sexual intercourse compared with current practice.DesignCluster randomised trial with follow up two years after baseline (six months after intervention). A process evaluation investigated the delivery of sex education and broader features of each school.SettingTwenty five secondary schools in east Scotland.Participants8430 pupils aged 13-15 years; 7616 completed the baseline questionnaire and 5854 completed the two year follow up questionnaire.InterventionSHARE programme (intervention group) versus existing sex education (control programme).ResultsWhen the intervention group was compared with the conventional sex education group in an intention to treat analysis there were no differences in sexual activity or sexual risk taking by the age of 16 years. However, those in the intervention group reported less regret of first sexual intercourse with most recent partner (young men 9.9% difference, 95% confidence interval −18.7 to −1.0; young women 7.7% difference, −16.6 to 1.2). Pupils evaluated the intervention programme more positively, and their knowledge of sexual health improved. Lack of behavioural effect could not be linked to differential quality of delivery of intervention.ConclusionsCompared with conventional sex education this specially designed intervention did not reduce sexual risk taking in adolescents.

What is already known on this topic

Despite the widespread assumption that sex education delivered by teachers can reduce sexual risk taking in young people, there have been few randomised trials large enough to show this and none in the United KingdomSeveral quasi-experimental studies have concluded that sex education is effective, but most randomised trials suggest it is not

What this study adds

Improvements in teacher delivered whole class sex education have some beneficial effect on the quality of young people''s sexual relationships but do not influence sexual behaviour     

A cognitive behavioural intervention to reduce sexually transmitted infections among gay men: randomised trial

ObjectiveTo determine the effectiveness of a brief cognitive behavioural intervention in reducing the incidence of sexually transmitted infections among gay men.DesignRandomised controlled trial with 12 months'' follow up.SettingSexual health clinic in London.Participants343 gay men with an acute sexually transmitted infection or who reported having had unprotected anal intercourse in the past year.Results72% (361/499) of men invited to enter the study did so. 90% (308/343) of participants returned at least one follow up questionnaire or re-attended the clinic and requested a check up for sexually transmitted infections during follow up. At baseline, 37% (63/172) of the intervention group and 30% (50/166) of the control group reported having had unprotected anal intercourse in the past month. At 12 months, the proportions were 27% (31/114) and 32% ( 39/124) respectively (P=0.56). However, 31% (38/123) of the intervention group and 21% (35/168) of controls had had at least one new infection diagnosed at the clinic (adjusted odds ratio 1.66, 95% confidence interval 1.00 to 2.74). Considering only men who requested a check up for sexually transmitted infections, the proportion diagnosed with a new infection was 58% (53/91) for men in the intervention group and 43% (35/81) for men in the control group (adjusted odds ratio 1.84, 0.99 to 3.40). Using a regional database that includes information from 23 sexual health clinics in London, we determined that few participants had attended other sexual health clinics.ConclusionsThis behavioural intervention was acceptable and feasible to deliver, but it did not reduce the risk of acquiring a new sexually transmitted infection among these gay men at high risk. Even carefully designed interventions should not be assumed to bring benefit. It is important to evaluate their effects in randomised trials with objective clinical end points.

What is already known on this topic

The need for effective HIV prevention strategies based on reducing sexual risk behaviour remains importantFew interventions to reduce sexual risk behaviour have been rigorously evaluated using randomised controlled trials

What this study adds

This is the first randomised controlled trial of an intervention addressing sexual behaviour in homosexual men that uses sexually transmitted infections and self reported behaviour as end pointsThe intervention was brief and feasible to use in a busy clinic, but it did not reduce the risk of participants acquiring new infectionsThe potential for behavioural interventions to do more harm than good needs to be taken seriously     

Multifactorial intervention after a fall in older people with cognitive impairment and dementia presenting to the accident and emergency department: randomised controlled trial

ObjectiveTo determine the effectiveness of multifactorial intervention after a fall in older patients with cognitive impairment and dementia attending the accident and emergency department.DesignRandomised controlled trial.Participants274 cognitively impaired older people (aged 65 or over) presenting to the accident and emergency department after a fall: 130 were randomised to assessment and intervention and 144 were randomised to assessment followed by conventional care (control group).SettingTwo accident and emergency departments, Newcastle upon Tyne.ResultsIntention to treat analysis showed no significant difference between intervention and control groups in proportion of patients who fell during 1 year''s follow up (74% (96/130) and 80% (115/144), relative risk ratio 0.92, 95% confidence interval 0.81 to 1.05). No significant differences were found between groups for secondary outcome measures.ConclusionsMultifactorial intervention was not effective in preventing falls in older people with cognitive impairment and dementia presenting to the accident and emergency department after a fall.

What is already known on this topic

Multifactorial intervention prevents falls in cognitively normal older people living in the community and in those who present to the accident and emergency department after a fallFall prevention strategies have not been tested by controlled trials in patients with cognitive impairment and dementia who fall

What this study adds

No benefit was shown from multifactorial assessment and intervention after a fall in patients with cognitive impairment and dementia presenting to the accident and emergency departmentThe intervention was less effective in these patients than in cognitively normal older people     

Life Expectancy in a Large Cohort of Type 2 Diabetes Patients Treated in Primary Care (ZODIAC-10)

Background

Most longitudinal studies showed increased relative mortality in individuals with type 2 diabetes mellitus until now. As a result of major changes in treatment regimes over the past years, with more stringent goals for metabolic control and cardiovascular risk management, improvement of life expectancy should be expected. In our study, we aimed to assess present-day life expectancy of type 2 diabetes patients in an ongoing cohort study.

Methodology and Principal Findings

We included 973 primary care type 2 diabetes patients in a prospective cohort study, who were all participating in a shared care project in The Netherlands. Vital status was assessed from May 2001 till May 2007. Main outcome measurement was life expectancy assessed by transforming actual survival time to standardised survival time allowing adjustment for the baseline mortality rate of the general population. At baseline, mean age was 66 years, mean HbA_1c 7.0%. During a median follow-up of 5.4 years, 165 patients died (78 from cardiovascular causes), and 17 patients were lost to follow-up. There were no differences in life expectancy in subjects with type 2 diabetes compared to life expectancy in the general population. In multivariate Cox regression analyses, concentrating on the endpoints ‘all-cause’ and cardiovascular mortality, a history of cardiovascular disease: hazard ratio (HR) 1.71 (95% confidence interval (CI) 1.23–2.37), and HR 2.59 (95% CI 1.56–4.28); and albuminuria: HR 1.72 (95% CI 1.26–2.35), and HR 1.83 (95% CI 1.17–2.89), respectively, were significant predictors, whereas smoking, HbA_1c, systolic blood pressure and diabetes duration were not.

Conclusions

This study shows a normal life expectancy in a cohort of subjects with type 2 diabetes patients in primary care when compared to the general population. A history of cardiovascular disease and albuminuria, however, increased the risk of a reduction of life expectancy. These results show that, in a shared care environment, a normal life expectancy is achievable in type 2 diabetes patients.     

Testing for Helicobacter pylori infection: validation and diagnostic yield of a near patient test in primary care

ObjectiveTo evaluate the performance of a near patient test for Helicobacter pylori infection in primary care.DesignValidation study performed within a randomised trial of four management strategies for dyspepsia.Setting43 general practices around Nottingham.Subjects394 patients aged 18-70 years presenting with recent onset dyspepsia.ResultsWhen used in primary care FlexSure test had a sensitivity and specificity of 67% (95% confidence interval 59% to 75%) and 98% (95% to 99%) compared with a sensitivity and specificity of 92% (87% to 97%) and 90% (83% to 97%) when used previously in secondary care. Of the H pylori test and refer group 14% (28/199) were found to have conditions for which H pylori eradication was appropriate compared with 23% (39/170) of the group referred directly for endoscopy.ConclusionsWhen used in primary care the sensitivity of the FlexSure test was significantly poorer than in secondary care. About a third of patients who would have benefited from H pylori eradication were not detected. Near patient tests need to be validated in primary care before they are incorporated into management policies for dyspepsia.

Key messages

• Near patient tests for H pylori infection have been recommended in the management of dyspepsia in primary care without proper evaluation
• Such tests should have a high sensitivity to avoid missing treatable illness related to infection
• The FlexSure near patient test had a lower sensitivity than previously reported in validation studies performed in secondary care
• Fewer than expected numbers of patients with H pylori related pathology were identified with the FlexSure in primary care

     

Effect of a Community-Based Nursing Intervention on Mortality in Chronically Ill Older Adults: A Randomized Controlled Trial

Background

Improving the health of chronically ill older adults is a major challenge facing modern health care systems. A community-based nursing intervention developed by Health Quality Partners (HQP) was one of 15 different models of care coordination tested in randomized controlled trials within the Medicare Coordinated Care Demonstration (MCCD), a national US study. Evaluation of the HQP program began in 2002. The study reported here was designed to evaluate the survival impact of the HQP program versus usual care up to five years post-enrollment.

Methods and Findings

HQP enrolled 1,736 adults aged 65 and over, with one or more eligible chronic conditions (coronary artery disease, heart failure, diabetes, asthma, hypertension, or hyperlipidemia) during the first six years of the study. The intervention group (n = 873) was offered a comprehensive, integrated, and tightly managed system of care coordination, disease management, and preventive services provided by community-based nurse care managers working collaboratively with primary care providers. The control group (n = 863) received usual care. Overall, a 25% lower relative risk of death (hazard ratio [HR] 0.75 [95% CI 0.57–1.00], p = 0.047) was observed among intervention participants with 86 (9.9%) deaths in the intervention group and 111 (12.9%) deaths in the control group during a mean follow-up of 4.2 years. When covariates for sex, age group, primary diagnosis, perceived health, number of medications taken, hospital stays in the past 6 months, and tobacco use were included, the adjusted HR was 0.73 (95% CI 0.55–0.98, p = 0.033). Subgroup analyses did not demonstrate statistically significant interaction effects for any subgroup. No suspected program-related adverse events were identified.

Conclusions

The HQP model of community-based nurse care management appeared to reduce all-cause mortality in chronically ill older adults. Limitations of the study are that few low-income and non-white individuals were enrolled and implementation was in a single geographic region of the US. Additional research to confirm these findings and determine the model''s scalability and generalizability is warranted.

Efficacy of handrubbing with alcohol based solution versus standard handwashing with antiseptic soap: randomised clinical trial

ObjectiveTo compare the efficacy of handrubbing with an alcohol based solution versus conventional handwashing with antiseptic soap in reducing hand contamination during routine patient care.DesignRandomised controlled trial during daily nursing sessions of 2 to 3 hours.SettingThree intensive care units in a French university hospital.Participants23 healthcare workers.InterventionsHandrubbing with alcohol based solution (n=12) or handwashing with antiseptic soap (n=11) when hand hygiene was indicated before and after patient care. Imprints taken of fingertips and palm of dominant hand before and after hand hygiene procedure. Bacterial counts quantified blindly.ResultsWith handrubbing the median percentage reduction in bacterial contamination was significantly higher than with handwashing (83% v 58%, P=0.012), with a median difference in the percentage reduction of 26% (95% confidence interval 8% to 44%). The median duration of hand hygiene was 30 seconds in each group.ConclusionsDuring routine patient care handrubbing with an alcohol based solution is significantly more efficient in reducing hand contamination than handwashing with antiseptic soap.

What is already known on this topic

To improve compliance with hand hygiene during patient care, handrubbing with an alcohol based solution has been proposed as a substitute for handwashing because of its rapid action and accessibilityExperimental studies show that handrubbing is at least as effective as medicated soap in reducing artificial contamination of handsMany healthcare workers still have reservations regarding its efficacy and are reluctant to use this technique

What this study adds

When used in routine practice, handrubbing with an alcohol based solution after contact with patients achieved a greater reduction in bacterial contamination of hands than conventional handwashing with medicated soap
