Confidential inquiry into quality of care before admission to intensive care

Objective: To examine the prevalence, nature, causes, and consequences of suboptimal care before admission to intensive care units, and to suggest possible solutions. Design: Prospective confidential inquiry on the basis of structured interviews and questionnaires. Setting: A large district general hospital and a teaching hospital. Subjects: A cohort of 100 consecutive adult emergency admissions, 50 in each centre. Main outcome measures: Opinions of two external assessors on quality of care especially recognition, investigation, monitoring, and management of abnormalities of airway, breathing, and circulation, and oxygen therapy and monitoring. Results: Assessors agreed that 20 patients were well managed (group 1) and 54 patients received suboptimal care (group 2). Assessors disagreed on quality of management of 26 patients (group 3). The casemix and severity of illness, defined by the acute physiology and chronic health evaluation (APACHE II) score, were similar between centres and the three groups. In groups 1, 2, and 3 intensive care mortalities were 5 (25%), 26 (48%), and 6 (23%) respectively (P=0.04) (group 1 versus group 2, P=0.07). Hospital mortalities were 7 (35%), 30 (56%), and 8 (31%) (P=0.07) and standardised hospital mortality ratios (95% confidence intervals) were 1.23 (0.49 to 2.54), 1.4 (0.94 to 2.0), and 1.26 (0.54 to 2.48) respectively. Admission to intensive care was considered late in 37 (69%) patients in group 2. Overall, a minimum of 4.5% and a maximum of 41% of admissions were considered potentially avoidable. Suboptimal care contributed to morbidity or mortality in most instances. The main causes of suboptimal care were failure of organisation, lack of knowledge, failure to appreciate clinical urgency, lack of supervision, and failure to seek advice. Conclusions: The management of airway, breathing, and circulation, and oxygen therapy and monitoring in severely ill patients before admission to intensive care units may frequently be suboptimal. Major consequences may include increased morbidity and mortality and requirement for intensive care. Possible solutions include improved teaching, establishment of medical emergency teams, and widespread debate on the structure and process of acute care.

Key messages

• Suboptimal management of oxygen therapy, airway, breathing, circulation, and monitoring before admission to intensive care occurred in over half of a consecutive cohort of acute adult emergency patients. This may be associated with increased morbidity, mortality, and avoidable admissions to intensive care
• At least 39% of acute adult emergency patients were admitted to intensive care late in the clinical course of the illness
• Major causes of suboptimal care included failure of organisation, lack of knowledge, failure to appreciate clinical urgency, lack of supervision, and failure to seek advice
• A medical emergency team may be useful in responding pre-emptively to the clinical signs of life threatening dysfunction of airway, breathing, and circulation, rather than relying on a cardiac arrest team
• The structure and process of acute care and their importance require major re-evaluation and debate

     

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

     

Cost effectiveness of community leg ulcer clinics: randomised controlled trial

Objectives: To establish the relative cost effectiveness of community leg ulcer clinics that use four layer compression bandaging versus usual care provided by district nurses. Design: Randomised controlled trial with 1 year of follow up. Setting: Eight community based research clinics in four trusts in Trent. Subjects: 233 patients with venous leg ulcers allocated at random to intervention (120) or control (113) group. Interventions: Weekly treatment with four layer bandaging in a leg ulcer clinic (clinic group) or usual care at home by the district nursing service (control group). Main outcome measures: Time to complete ulcer healing, patient health status, and recurrence of ulcers. Satisfaction with care, use of services, and personal costs were also monitored. Results: The ulcers of patients in the clinic group tended to heal sooner than those in the control group over the whole 12 month follow up (log rank P=0.03). At 12 weeks, 34% of patients in the clinic group were healed compared with 24% in the control. The crude initial healing rate of ulcers in intervention compared with control patients was 1.45 (95% confidence interval 1.04 to 2.03). No significant differences were found between the groups in health status. Mean total NHS costs were £878.06 per year for the clinic group and £859.34 for the control (P=0.89). Conclusions: Community based leg ulcer clinics with trained nurses using four layer bandaging is more effective than traditional home based treatment. This benefit is achieved at a small additional cost and could be delivered at reduced cost if certain service configurations were used.

Key messages

• Leg ulcer clinics based in the community using four layer compression bandaging can be more clinically effective than usual care provided by the district nursing service
• Community based leg ulcer clinics could be provided more cost effectively than usual home based care for venous leg ulcers
• Recurrence of venous leg ulcers is an important variable that should be measured in future trials of venous leg ulcer care
• It is difficult to measure improvements in health related quality of life among people with venous leg ulcers

     

Cost-Effectiveness of a Specialist Geriatric Medical Intervention for Frail Older People Discharged from Acute Medical Units: Economic Evaluation in a Two-Centre Randomised Controlled Trial (AMIGOS)

BackgroundPoor outcomes and high resource-use are observed for frail older people discharged from acute medical units. A specialist geriatric medical intervention, to facilitate Comprehensive Geriatric Assessment, was developed to reduce the incidence of adverse outcomes and associated high resource-use in this group in the post-discharge period.ObjectiveTo examine the costs and cost-effectiveness of a specialist geriatric medical intervention for frail older people in the 90 days following discharge from an acute medical unit, compared with standard care.MethodsEconomic evaluation was conducted alongside a two-centre randomised controlled trial (AMIGOS). 433 patients (aged 70 or over) at risk of future health problems, discharged from acute medical units within 72 hours of attending hospital, were recruited in two general hospitals in Nottingham and Leicester, UK. Participants were randomised to the intervention, comprising geriatrician assessment in acute units and further specialist management, or to control where patients received no additional intervention over and above standard care. Primary outcome was incremental cost per quality adjusted life year (QALY) gained.ResultsWe undertook cost-effectiveness analysis for 417 patients (intervention: 205). The difference in mean adjusted QALYs gained between groups at 3 months was -0.001 (95% confidence interval [CI]: -0.009, 0.007). Total adjusted secondary and social care costs, including direct costs of the intervention, at 3 months were £4412 (€5624, $6878) and £4110 (€5239, $6408) for the intervention and standard care groups, the incremental cost was £302 (95% CI: 193, 410) [€385, $471]. The intervention was dominated by standard care with probability of 62%, and with 0% probability of cost-effectiveness (at £20,000/QALY threshold).ConclusionsThe specialist geriatric medical intervention for frail older people discharged from acute medical unit was not cost-effective. Further research on designing effective and cost-effective specialist service for frail older people discharged from acute medical units is needed.

Randomised controlled trial comparing effectiveness and acceptability of an early discharge,hospital at home scheme with acute hospital care

Objective: To compare effectiveness and acceptability of early discharge to a hospital at home scheme with that of routine discharge from acute hospital. Design: Pragmatic randomised controlled trial. Setting: Acute hospital wards and community in north of Bristol, with a catchment population of about 224 000 people. Subjects: 241 hospitalised but medically stable elderly patients who fulfilled criteria for early discharge to hospital at home scheme and who consented to participate. Interventions: Patients’ received hospital at home care or routine hospital care. Main outcome measures: Patients’ quality of life, satisfaction, and physical functioning assessed at 4 weeks and 3 months after randomisation to treatment; length of stay in hospital and in hospital at home scheme after randomisation; mortality at 3 months. Results: There were no significant differences in patient mortality, quality of life, and physical functioning between the two arms of the trial at 4 weeks or 3 months. Only one of 11 measures of patient satisfaction was significantly different: hospital at home patients perceived higher levels of involvement in decisions. Length of stay for those receiving routine hospital care was 62% (95% confidence interval 51% to 75%) of length of stay in hospital at home scheme. Conclusions: The early discharge hospital at home scheme was similar to routine hospital discharge in terms of effectiveness and acceptability. Increased length of stay associated with the scheme must be interpreted with caution because of different organisational characteristics of the services.

Key messages

• Pressure on hospital beds, the increasing age of the population, and high costs associated with acute hospital care have fuelled the search for alternatives to inpatient hospital care
• There were no significant differences between early discharge to hospital at home scheme and routine hospital care in terms of patient quality of life, physical functioning, and most measures of patient satisfaction
• Length of stay for hospital patients was significantly shorter than that of hospital at home patients, but, owing to qualitative differences between the two interventions, this does not necessarily mean differences in effectiveness
• Early discharge to hospital at home provides an acceptable alternative to routine hospital care in terms of effectiveness and patient acceptability

     

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

     

Cost-Effectiveness of an Intervention to Reduce Emergency Re-Admissions to Hospital among Older Patients

Background

The objective is to estimate the cost-effectiveness of an intervention that reduces hospital re-admission among older people at high risk. A cost-effectiveness model to estimate the costs and health benefits of the intervention was implemented.

Methodology/Principal Findings

The model used data from a randomised controlled trial conducted in an Australian tertiary metropolitan hospital. Participants were acute medical admissions aged >65 years with at least one risk factor for re-admission: multiple comorbidities, impaired functionality, aged >75 years, recent multiple admissions, poor social support, history of depression. The intervention was a comprehensive nursing and physiotherapy assessment and an individually tailored program of exercise strategies and nurse home visits with telephone follow-up; commencing in hospital and continuing following discharge for 24 weeks. The change to cost outcomes, including the costs of implementing the intervention and all subsequent use of health care services, and, the change to health benefits, represented by quality adjusted life years, were estimated for the intervention as compared to existing practice. The mean change to total costs and quality adjusted life years for an average individual over 24 weeks participating in the intervention were: cost savings of $333 (95% Bayesian credible interval $ -1,932∶1,282) and 0.118 extra quality adjusted life years (95% Bayesian credible interval 0.1∶0.136). The mean net-monetary-benefit per individual for the intervention group compared to the usual care condition was $7,907 (95% Bayesian credible interval $5,959∶$9,995) for the 24 week period.

Conclusions/Significance

The estimation model that describes this intervention predicts cost savings and improved health outcomes. A decision to remain with existing practices causes unnecessary costs and reduced health. Decision makers should consider adopting this program for elderly hospitalised patients.     

Improving the health behaviours of elderly people: randomised controlled trial of a general practice education programme

ObjectivesTo establish the effect of an educational intervention for general practitioners on the health behaviours and wellbeing of elderly patients.DesignRandomised controlled trial with 1 year follow up.SettingMetropolitan general practices in Melbourne, Australia.Subjects42 general practitioners and 267 of their patients aged over 65 years.InterventionEducational and clinical practice audit programme for general practitioners on health promotion for elderly people.ResultsPatients in the intervention group had increased (a) walking by an average of 88 minutes per fortnight, (b) frequency of pleasurable activities, and (c) self rated health compared with the control group. No change was seen in drug usage, rate of influenza vaccination, functional status, or psychological wellbeing as a result of the intervention. Extrapolations of the known effect of these changes in behaviour suggest mortality could be reduced by 22% if activity was sustained for 5 years.ConclusionsEducation of the general practitioners had a positive effect on health outcomes of their elderly patients. General practitioners may have considerable public health impact in promotion of health for elderly patients.

Key messages

• Few educational interventions for doctors have shown benefit to the health of patients
• Elderly people were identified in the UK health initiatives as in need of additional attention, and levels of health protective behaviours were low in community surveys
• A multifaceted educational intervention for general practitioners was effective in improving walking behaviour, self rated health status, and the frequency of social contacts in elderly patients
• General practitioners are effective in improving health and health behaviours in their elderly patients

     

Mental health problems of homeless children and families: longitudinal study

Objective: To establish the mental health needs of homeless children and families before and after rehousing. Design: Cross sectional, longitudinal study. Setting: City of Birmingham. Subjects: 58 rehoused families with 103 children aged 2-16 years and 21 comparison families of low socioeconomic status in stable housing, with 54 children. Main outcome measures: Children’s mental health problems and level of communication; mothers’ mental health problems and social support one year after rehousing. Results: Mental health problems remained significantly higher in rehoused mothers and their children than in the comparison group (mothers 26% v 5%, P=0.04; children 39% v 11%, P=0.0003). Homeless mothers continued to have significantly less social support at follow up. Mothers with a history of abuse and poor social integration were more likely to have children with persistent mental health problems. Conclusions: Homeless families have a high level of complex needs that cannot be met by conventional health services and arrangements. Local strategies for rapid rehousing into permanent accommodation, effective social support and health care for parents and children, and protection from violence and intimidation should be developed and implemented.

Key messages

• Homeless children and their mothers have a high level of mental health problems
• Homeless families experience many risk factors, such as domestic violence, abuse, and family and social disruption
• In two fifths of children and a quarter of mothers, mental health problems persisted after rehousing
• In contrast with a comparison group of families of low socioeconomic status, a substantial proportion of homeless families remained residentially and socially unstable

     

Effect of preventive home visits by a nurse on the outcomes of frail elderly people in the community: a randomized controlled trial

BACKGROUND: Timely recognition and prevention of health problems among elderly people have been shown to improve their health. In this randomized controlled trial the authors examined the impact of preventive home visits by a nurse compared with usual care on the outcomes of frail elderly people living in the community. METHODS: A screening questionnaire identified eligible participants (those aged 70 years or more at risk of sudden deterioration in health). Those randomly assigned to the visiting nurse group were assessed and followed up in their homes for 14 months. The primary outcome measure was the combined rate of deaths and admissions to an institution, and the secondary outcome measure the rate of health services utilization, during the 14 months; these rates were determined through a medical chart audit by a research nurse who was blind to group allocation. RESULTS: The questionnaire was mailed to 415 elderly people, of whom 369 (88.9%) responded. Of these, 198 (53.7%) were eligible, and 142 consented to participate and were randomly assigned to either the visiting nurse group (73) or the usual care group (69). The combined rate of deaths and admissions to an institution was 10.0% in the visiting nurse group and 5.8% in the usual care group (p = 0.52). The rate of health services utilization did not differ significantly between the 2 groups. Influenza and pneumonia vaccination rates were significantly higher in the visiting nurse group (90.1% and 81.9%) than in the usual care group (53.0% and 0%) (p < 0.001). INTERPRETATION: The trial failed to show any effect of a visiting nurse other than vastly improved vaccination coverage.     

Underperforming doctors: a postal survey of the Northern Deanery

Objectives: To discover the perceived size of pool of doctors considered to be underperforming in general practice in the Northern Deanery and to discover whether these perceptions are based on formal assessments. Design: Postal questionnaire. Setting: Area covered by the Northern Deanery. Subjects: Seven health authority directors of primary care, seven secretaries of local medical committees, and 14 chief officers of community health councils. Results: The response rate was 100% for directors of primary care and secretaries of local medical committees and, after one reminder, 92% for chief officers of community health councils. Numbers of doctors perceived to be underperforming ranged from none to over 15 in different health authority areas. Main areas for concern were communication skills, clinical skills, and management skills. Patients’ representatives were concerned about lack of power of patients and health authorities and doctors’ lack of accountability. Health authorities were concerned about lack of power, identification of underperforming doctors, and doctors’ professional loyalty. Local medical committees were concerned about the problem of identifying underperformance. A number of methods were used for identification, and there was no common method applied. Conclusions: The number of doctors thought to be underperforming was small. Work still needs to be done on developing tools that can be used in everyday practice to enable doctors to confirm for themselves, their colleagues, and their patients that they are providing an adequate level of care.

Key messages

• To quantify the problem of underperforming general practitioners in the Northern Deanery, a postal survey was carried out among representatives of healthcare commissioners, doctors, and patients
• A small but not insignificant number of doctors were identified as providing a poor level of performance
• Main areas for concern were communication skills, clinical skills, and management skills.
• Various methods were used for identifying underperforming doctors, but there was no common method applied
• Perceived problems with the present system of dealing with underperforming doctors included identification, lack of power of patients and health authorities, and doctors’ professional loyalty and lack of accountability

     

Oral health care for frail elderly people: actual state and opinions of dentists towards a well-organised community approach

Objective: This study was undertaken to provide an analysis of the actual oral heath care for frail elderly people living in different settings and to explore opinions of dentists towards new concepts in developing a community approach. Method: Data were collected from a sample of 101 dentists (15%) in the county of Antwerp using a self‐administered 30‐item questionnaire including questions about age, gender, education, organisational aspects of dental surgery, questions concerning dentists’ own contribution to oral healthcare services for frail elderly people and statements concerning opinions and attitude toward the organisation of oral health care for frail elderly people. At the same time, qualitative data were collected from focus group sessions with all participating dentists. Non‐parametric analysis was used to explore possible relationships between opinion and possible explanatory variables. Results: Half of the dentists offered dental services to residential or nursing homes (mean number of treatments a year: 5.4) and at home (mean number of treatments a year: 2.4). Prosthetic treatments such as relieving denture pressure points, repairing, rebasing and making new dentures were carried out in 77.4% and 76.7% of the cases in residential or nursing homes and at home respectively. Extractions were carried out in 16% and 18.6% of the cases in both living situations respectively. The main reasons for dentists refusing domiciliary oral health care were the absence of dental equipment (63%), lack of time (19%), with 11% convincing the patients to be treated in their dental surgery. Analysis showed different opinions of dentists depending on age, gender and university of education; however, statistically significant differences were only found by age. Conclusion: The older the dentist, the greater the tendency to refuse domiciliary oral healthcare services. The younger dentists were reluctant to cooperate in the provision of oral health care in a structured community approach.     

Are elderly people living alone an at risk group?

OBJECTIVE--To test the hypothesis that elderly people living alone are an at risk group with a high level of morbidity that makes high demands on health and social services. DESIGN--Secondary analysis of data from a community survey of 239 people aged 75 and over, identified from general practitioners'' age-sex registers. SETTING--Nine practices in the London boroughs of Brent and Islington. MAIN OUTCOME MEASURES--Scores on the mini-mental state examination; stated satisfaction with life; assessment of mobility; numbers of diagnoses of major physical problems; numbers of prescribed drugs taken; urinary incontinence; alcohol consumption; contacts with general practitioners and hospital outpatient and inpatient services; contact with community health and social services. RESULTS--There were significantly more women among those living alone (93/120 (78%) v 63/119 (53%); p < 0.0005) and the median age of elderly people living alone was higher (81 v 80; p < 0.04). Those living alone and those living with others showed no significant differences in measures of cognitive impairment, numbers of major physical diagnoses, impaired mobility, or use of general practitioner or hospital services. Stated satisfaction with life was somewhat higher in those living alone. Elderly people living alone were significantly more likely to have contact with chiropody, home help, and meals on wheels services and less likely to have someone they could contact in an emergency or at night. Living alone increased the likelihood of contact with one or more community health professionals (district nurses, health visitors, or chiropodists) considered as a group and also increased the likelihood of contact with social services as a whole. There was a tendency for more of those living alone than those living with others to have home visits from their general practitioners, but there were no significant differences in contact with hospital services between the two groups. CONCLUSIONS--Elderly people living alone do not have an excess of morbidity compared with those living with others and do not seem to be an at risk group requiring specifically targeted assessments. More help is needed to provide elderly people living alone with a point of contact in case of emergency.     

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     

Outcome of low back pain in general practice: a prospective study

Objectives: To investigate the claim that 90% of episodes of low back pain that present to general practice have resolved within one month. Design: Prospective study of all adults consulting in general practice because of low back pain over 12 months with follow up at 1 week, 3 months, and 12 months after consultation. Setting: Two general practices in south Manchester. Subjects: 490 subjects (203 men, 287 women) aged 18-75 years. Main outcome measures: Proportion of patients who have ceased to consult with low back pain after 3 months; proportion of patients who are free of pain and back related disability at 3 and 12 months. Results: Annual cumulative consultation rate among adults in the practices was 6.4%. Of the 463 patients who consulted with a new episode of low back pain, 275 (59%) had only a single consultation, and 150 (32%) had repeat consultations confined to the 3 months after initial consultation. However, of those interviewed at 3 and 12 months follow up, only 39/188 (21%) and 42/170 (25%) respectively had completely recovered in terms of pain and disability. Conclusions: The results are consistent with the interpretation that 90% of patients with low back pain in primary care will have stopped consulting with symptoms within three months. However most will still be experiencing low back pain and related disability one year after consultation.

Key messages

• It is widely believed that 90% of episodes of low back pain seen in general practice resolve within one month
• In a large population based study we examined the outcome of episodes of low back pain in general practice with respect to both consultation behaviour and self reported pain and disability
• While 90% of subjects consulting general practice with low back pain ceased to consult about the symptoms within three months, most still had substantial low back pain and related disability
• Only 25% of the patients who consulted about low back pain had fully recovered 12 months later
• Since most consulters continue to have long term low back pain and disability, effective early treatment could reduce the burden of these symptoms and their social, economic, and medical impact

     

Injection with methylprednisolone proximal to the carpal tunnel: randomised double blind trial

ObjectiveTo assess the effect of a 40 mg methylprednisolone injection proximal to the carpal tunnel in patients with the carpal tunnel syndrome.DesignRandomised double blind placebo controlled trial. SettingOutpatient neurology clinic in a district general hospital.ParticipantsPatients with symptoms of the carpal tunnel syndrome for more than 3 months, confirmed by electrophysiological tests and aged over 18 years.InterventionInjection with 10 mg lignocaine (lidocaine) or 10 mg lignocaine and 40 mg methylprednisolone. Non-responders who had received lignocaine received 40 mg methylprednisolone and 10 mg lignocaine and were followed in an open study.ResultsAt 1 month 6 (20%) of 30 patients in the control group had improved compared with 23 (77%) of 30 patients the intervention group (difference 57% (95% confidence interval 36% to 77%)). After 1 year, 2 of 6 improved patients in the control group did not need a second treatment, compared with 15 of 23 improved patients in the intervention group (difference 43% (23% to 63%). Of the 28 non-responders in the control group, 24 (86%) improved after methylprednisolone. Of these 24 patients, 12 needed surgical treatment within one year.ConclusionA single injection with steroids close to the carpal tunnel may result in long term improvement and should be considered before surgical decompression.

Key messages

• Corticosteroid injections into the carpal tunnel may damage the nerve, and any treatment benefits may be of short duration
• A single injection with steroids proximal to the carpal tunnel improves 77% of patients with the carpal tunnel syndrome at one month after treatment
• This single injection is still effective at one year in half of the patients
• Injections proximal to the carpal tunnel have no side effects and are easier to carry out than injections into the carpal tunnel

     

Effects of preventive home visits to elderly people.

OBJECTIVES--To assess the effect of preventive home visits by public health nurses on the state of health of and use of services by elderly people living at home. DESIGN--Randomised controlled trial. SETTING--General population of elderly people in one of the southern regions of the Netherlands. SUBJECTS--580 subjects aged between 75 and 84 years randomly allocated to intervention (292) or control (288) group. INTERVENTIONS--Four visits a year over three years in intervention group. Control group received no home visits. MAIN OUTCOME MEASURES--Self rated health, functional state, well being, loneliness, aspects of the mental state (depressive complaints, memory disturbances), and mortality. Use of services and costs. RESULTS--Visits had no effect on the health of the subjects. In the group visited no higher scores were seen on health related measures, fewer died (42 (14%) v 50 (17%)), and community care increased slightly. In the control group more were referred to outpatient clinics (166 (66%) v 132 (55%)), and they had a 40% increased risk of admission (incidence rate ratio 1.4; 90% confidence interval 1.2 to 1.6). No differences were found in long term institutional care, and overall expenditure per person in the intervention group exceeded that in the control group by 4%. Additional analyses showed that visits were effective for subjects who initially rated their health as poor. CONCLUSIONS--Preventive home visits are not beneficial for the general population of elderly people living at home but might be effective when restricted to subjects with poor health.     

Long term relative survival after surgery for abdominal aortic aneurysm in Western Australia: population based study

Objective: To determine the long term relative survival of all patients who had surgery for abdominal aortic aneurysm in Western Australia during 1985-94. Design: Population based study. Setting: Western Australia. Subjects: All patients who had had surgery for abdominal aortic aneurysm in Western Australia during 1985-94. Main outcome measures: Morbidity and mortality data of patients admitted and surgically treated for abdominal aortic aneurysm in Western Australia during 1985-94. Elective, ruptured, and acute non-ruptured cases were analysed separately. Independent analyses for sex and patients aged 80 years or more were also undertaken. Postoperative (>30 days) relative survival was assessed against age and sex matched controls. Results: Overall, 1475 (1257 men, 218 women) cases were identified. The crude five year survival after elective surgery, including deaths within 30 days of surgery, was 79% for both men and women. When compared with a matched population the five year relative survival after elective surgery was 94.9% (95% confidence interval 89.9% to 99.9%) for men but only 88.0% (76.3% to 99.7%) for women. The five year relative survival of those aged 80 years and over was good: 116.6% (89.1% to 144.0%) compared with 92.4% (87.7% to 97.0%) for those under 80 years of age (men and women combined). Cardiovascular disease caused 57.8% of the 341 deaths after 30 days. Conclusion: In a condition such as abdominal aortic aneurysm, which occurs in elderly patients, relative survival is more clinically meaningful than crude survival. The five year relative survival in cases of elective and ruptured abdominal aortic aneurysm was better in men than in women. This is probably because of greater comorbidity in women with abdominal aortic aneurysm and this deserves more attention in the future. The long term survival outcome in octogenarians supports surgery in selected cases.

Key messages

• Background mortality for conditions such as abdominal aortic aneurysm in elderly patients needs to be taken into account when assessing long term survival after surgery
• Relative survival methodology can correct for background mortality
• The five year relative survival for patients surviving beyond 30 days of elective surgery for abdominal aortic aneurysm was 95% for men and 88% for women
• For octogenarians, five year survival after elective surgery was greater than that expected of an age matched population
• Age over 80 years should not preclude consideration for elective surgery for abdominal aortic aneurysm

     

Increasing Short-Stay Unplanned Hospital Admissions among Children in England; Time Trends Analysis ’97–‘06

Background

Timely care by general practitioners in the community keeps children out of hospital and provides better continuity of care. Yet in the UK, access to primary care has diminished since 2004 when changes in general practitioners'' contracts enabled them to ‘opt out’ of providing out-of-hours care and since then unplanned pediatric hospital admission rates have escalated, particularly through emergency departments. We hypothesised that any increase in isolated short stay admissions for childhood illness might reflect failure to manage these cases in the community over a 10 year period spanning these changes.

Methods and Findings

We conducted a population based time trends study of major causes of hospital admission in children <10 years using the Hospital Episode Statistics database, which records all admissions to all NHS hospitals in England using ICD10 codes. Outcomes measures were total and isolated short stay unplanned hospital admissions (lasting less than 2 days without readmission within 28 days) from 1997 to 2006. Over the period annual unplanned admission rates in children aged <10 years rose by 22% (from 73.6/1000 to 89.5/1000 child years) with larger increases of 41% in isolated short stay admissions (from 42.7/1000 to 60.2/1000 child years). There was a smaller fall of 12% in admissions with length of stay of >2 days. By 2006, 67.3% of all unplanned admissions were isolated short stays <2 days. The increases in admission rates were greater for common non-infectious than infectious causes of admissions.

Conclusions

Short stay unplanned hospital admission rates in young children in England have increased substantially in recent years and are not accounted for by reductions in length of in-hospital stay. The majority are isolated short stay admissions for minor illness episodes that could be better managed by primary care in the community and may be evidence of a failure of primary care services.     

Human albumin administration in critically ill patients: systematic review of randomised controlled trials

Objective: To quantify effect on mortality of administering human albumin or plasma protein fraction during management of critically ill patients. Design: Systematic review of randomised controlled trials comparing administration of albumin or plasma protein fraction with no administration or with administration of crystalloid solution in critically ill patients with hypovolaemia, burns, or hypoalbuminaemia. Subjects: 30 randomised controlled trials including 1419 randomised patients. Main outcome measure: Mortality from all causes at end of follow up for each trial. Results: For each patient category the risk of death in the albumin treated group was higher than in the comparison group. For hypovolaemia the relative risk of death after albumin administration was 1.46 (95% confidence interval 0.97 to 2.22), for burns the relative risk was 2.40 (1.11 to 5.19), and for hypoalbuminaemia it was 1.69 (1.07 to 2.67). Pooled relative risk of death with albumin administration was 1.68 (1.26 to 2.23). Pooled difference in the risk of death with albumin was 6% (95% confidence interval 3% to 9%) with a fixed effects model. These data suggest that for every 17 critically ill patients treated with albumin there is one additional death. Conclusions: There is no evidence that albumin administration reduces mortality in critically ill patients with hypovolaemia, burns, or hypoalbuminaemia and a strong suggestion that it may increase mortality. These data suggest that use of human albumin in critically ill patients should be urgently reviewed and that it should not be used outside the context of rigorously conducted, randomised controlled trials.

Key messages

• Human albumin solution has been used in the treatment of critically ill patients for over 50 years
• Currently, the licensed indications for use of albumin are emergency treatment of shock, acute management of burns, and clinical situations associated with hypoproteinaemia
• Our systematic review of randomised controlled trials showed that, for each of these patient categories, the risk of death in the albumin treated group was higher than in the comparison group
• The pooled relative risk of death with albumin was 1.68 (95% confidence interval 1.26 to 2.23) and the pooled difference in the risk of death was 6% (3% to 9%) or six additional deaths for every 100 patients treated
• We consider that use of human albumin solution in critically ill patients should be urgently reviewed
