Comparative effectiveness of post-discharge interventions for hospitalized smokers: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: A hospital admission offers smokers an opportunity to quit. Smoking cessation counseling provided in the hospital is effective, but only if it continues for more than one month after discharge. Providing smoking cessation medication at discharge may add benefit to counseling. A major barrier to translating this research into clinical practice is sustaining treatment during the transition to outpatient care. An evidence-based, practical, cost-effective model that facilitates the continuation of tobacco treatment after discharge is needed. This paper describes the design of a comparative effectiveness trial testing a hospital-initiated intervention against standard care. Methods/design: A 2-arm randomized controlled trial compares the effectiveness of standard post-discharge care with a multi-component smoking cessation intervention provided for 3 months after discharge. Current smokers admitted to Massachusetts General Hospital who receive bedside smoking cessation counseling, intend to quit after discharge and are willing to consider smoking cessation medication are eligible. Study participants are recruited following the hospital counseling visit and randomly assigned to receive Standard Care or Extended Care after hospital discharge. Standard Care includes a recommendation for a smoking cessation medication and information about community resources. Extended Care includes up to 3 months of free FDA-approved smoking cessation medication and 5 proactive computerized telephone calls that use interactive voice response technology to provide tailored motivational messages, offer additional live telephone counseling calls from a smoking cessation counselor, and facilitate medication refills. Outcomes are assessed at 1, 3, and 6 months after hospital discharge. The primary outcomes are self-reported and validated 7-day point prevalence tobacco abstinence at 6 months. Other outcomes include short-term and sustained smoking cessation, post-discharge utilization of smoking cessation treatment, hospital readmissions and emergency room visits, and program cost per quit. DISCUSSION: This study tests a potentially disseminable smoking intervention model for hospitalized smokers. If effective and widely adopted, it could help to reduce population smoking rates and thereby reduce tobacco-related mortality, morbidity, and health care costs.     

Web-based smoking cessation intervention that transitions from inpatient to outpatient: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: E-health tools are a new mechanism to expand patient care, allowing supplemental resources to usual care, including enhanced patient-provider communication. These applications to smoking cessation have not yet been tested in a hospitalized patient sample. This project aims to evaluate the effectiveness and cost-effectiveness of a tailored web-based and e-message smoking cessation program for current smokers that, upon hospital discharge, transitions the patient to continue a quit attempt when home (Decide2Quit). DESIGN: A randomized two-arm follow-up design will test the effectiveness of an evidence- and theoretically-based smoking cessation program designed for post-hospitalization. METHODS: 1488 patients aged 19 or older, who smoked cigarettes in the previous 30 days, are being recruited from 27 patient care areas of a large urban university hospital. Study eligible hospitalized patients receiving tobacco cessation usual care are offered study referral. Trained hospital staff assist the 744 patients who are being randomized to the intervention arm with registration and orientation to the intervention website. This e-mail and web-based program offers tailored messages as well as education, self-assessment and planning aids, and social support to promote tobacco use cessation. Condition-blind study staff assess participants for tobacco use history and behaviors, tobacco use costs-related information, co-morbidities and psychosocial factors at 0, 3, 6, and 12 months. The primary outcome is self-reported 30-day tobacco abstinence at 6 months follow-up. Secondary outcomes include 7-day point prevalence quit rates at 3, 6, and 12 months follow-up, 30-day point prevalence quit rates at 3 and 12 months, biologically confirmed tobacco abstinence at 6-months follow-up, and multiple point-prevalence quit rates based on self-reported tobacco abstinence rates at each follow-up time period. Health care utilization and quality of life are assessed at baseline, and 6 and 12 months follow-up to measure program cost-effectiveness from the hospital, health care payer, patient, and societal perspectives. DISCUSSION: Given the impact of tobacco use on medical resources, establishing feasible, cost-effective methods for reducing tobacco use is imperative. Given the minimal hospital staff burden and the automated transition to a post-hospitalization tailored intervention, this program could be an easily disseminated approach.

Effect on smoking quit rate of telling patients their lung age: the Step2quit randomised controlled trial

Objective To evaluate the impact of telling patients their estimated spirometric lung age as an incentive to quit smoking.Design Randomised controlled trial.Setting Five general practices in Hertfordshire, England.Participants 561 current smokers aged over 35.Intervention All participants were offered spirometric assessment of lung function. Participants in intervention group received their results in terms of “lung age” (the age of the average healthy individual who would perform similar to them on spirometry). Those in the control group received a raw figure for forced expiratory volume at one second (FEV₁). Both groups were advised to quit and offered referral to local NHS smoking cessation services.Main outcome measures The primary outcome measure was verified cessation of smoking by salivary cotinine testing 12 months after recruitment. Secondary outcomes were reported changes in daily consumption of cigarettes and identification of new diagnoses of chronic obstructive lung disease.Results Follow-up was 89%. Independently verified quit rates at 12 months in the intervention and control groups, respectively, were 13.6% and 6.4% (difference 7.2%, P=0.005, 95% confidence interval 2.2% to 12.1%; number needed to treat 14). People with worse spirometric lung age were no more likely to have quit than those with normal lung age in either group. Cost per successful quitter was estimated at £280 (€366, $556). A new diagnosis of obstructive lung disease was made in 17% in the intervention group and 14% in the control group; a total of 16% (89/561) of participants.Conclusion Telling smokers their lung age significantly improves the likelihood of them quitting smoking, but the mechanism by which this intervention achieves its effect is unclear.Trial registration National Research Register N0096173751.     

High intensity smoking cessation interventions: Cardiac patients of low socioeconomic status and low intention to quit profit most

Background

Without assistance, smokers being admitted to the hospital for coronary heart disease often return to regular smoking within a year.

Objective

This study assessed the 12-month effectiveness of a telephone and a face-to-face counselling intervention on smoking abstinence among cardiac patients. Differential effects for subgroups varying in their socioeconomic status and intention to quit smoking were also studied.

Methods

A randomised controlled trial was used. During hospital stay, smokers hospitalised for coronary heart disease were assigned to usual care (n = 245), telephone counselling (n = 223) or face-to-face counselling (n = 157). Eligible patients were allocated to an intervention counselling group and received nicotine patches. After 12 months, self-reported continued abstinence was assessed and biochemically verified in quitters. Effects on smoking abstinence were tested using multilevel logistic regression analyses applying the intention-to-treat approach.

Results

Compared with usual care, differential effects of telephone and face-to-face counselling on continued abstinence were found in patients with a low socioeconomic status and in patients with a low quit intention. For these patients, telephone counselling increased the likelihood of abstinence threefold (OR = 3.10, 95?% CI 1.32–7.31, p = 0.01), whereas face-to-face counselling increased this likelihood fivefold (OR = 5.30, 95?% CI 2.13–13.17, p < 0.001). Considering the total sample, the interventions did not result in stronger effects than usual care.

Conclusion

Post-discharge telephone and face-to-face counselling interventions increased smoking abstinence rates at 12 months compared with usual care among cardiac patients of low socioeconomic status and low quit intentions. The present study indicates that patients of high socioeconomic status and high quit motivation require different cessation approaches.

     

Smoking cessation initiated during hospital stay for patients with coronary artery disease: a randomized controlled trial

Background

Programs for smoking cessation for cardiac patients are underused in Canada. We examined the efficacy of an intervention for smoking cessation for patients admitted to hospital for coronary artery bypass graft (CABG) or because of acute myocardial infarction (MI).

Methods

Nurses randomly assigned 276 sequential patients admitted because of acute MI or for CABG who met the inclusion criteria. Participants received an intensive or minimal smoking-cessation intervention. The minimal intervention included advice from physicians and nurses and 2 pamphlets. The intensive intervention included the minimal intervention plus 60 minutes of bedside counselling, take-home materials and 7 nurse-initiated counselling calls for 2 months after discharge. The outcomes were point prevalence of abstinence at 3, 6 and 12 months after discharge.

Results

The 12-month self-reported rate of abstinence was 62% among patients in the intensive group and 46% among those in the minimal group (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.2–3.1). Abstinence was confirmed for 54% of patients in the intensive group and 35% in the minimal group (OR 2.0, 95% CI 1.3–3.6). Abstinence was significantly lower among those who used pharmacotherapy than among those who did not (p < 0.001). Continuous 12-month abstinence was 57% in the intensive group and 39% in the minimal group (p < 0.01). It was significantly higher among patients admitted for CABG than among those admitted because of acute MI (p < 0.05).

Interpretation

Providing intensive programs for smoking cessation for patients admitted for CABG or because of acute MI could have a major impact on health and health care costs.Interventions for smoking cessation are underused in cardiac units in Canada,¹ even though coronary artery disease accounts for a large proportion of hospital admissions among adults aged 45 or more years.² Compared with the use of other secondary prevention and management measures (e.g., statins, acetylsalicylic acid, β-blockers and angiotensin-converting-enzyme inhibitors), the use of smoking-cessation measures among those with coronary artery disease results in greater reductions in mortality risk^1,3,4 and greater cost-effectiveness.⁵ Risk reductions in this group include a 32% decrease in nonfatal reinfarction, 36% decrease in mortality,³ 300% reduced risk for repeat coronary artery bypass graft (CABG),⁶ and a decreased risk for restenosis after percutaneous translumial coronary angioplasty from 55% to 38%.⁷In this study, we used an intensive intervention, which is the gold standard for smoking cessation among inpatients. When tested in the United States, this intervention resulted in the highest rates of 1-year confirmed cessation reported in the literature.⁸ The intervention involves 45–60 minutes of bedside education and counselling during hospital stay followed by 7 nurse-initiated telephone counselling sessions after discharge.⁹ US trials have reported 1-year confirmed cessation rates of 61% for this intensive intervention compared to 32% for a brief intervention when tested as a stand-alone program.¹⁰ When tested as part of a rehabilitation program for multiple cardiac risk factors, the cessation rates were 70% and 53%, respectively.¹¹ Despite the success of this approach among cardiac patients, interventions for smoking cessation in inpatients have not been widely adopted in Canada.In this randomized clinical trial, we investigated the efficacy of a minimal intervention and an intensive intervention for smoking cessation among patients admitted to hospital because of acute myocardial infarction or for CABG.     

Financial incentives for smoking cessation in lowincome smokers: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: Tobacco smoking is the leading avoidable cause of death in high-income countries. The smoking-related disease burden is borne primarily by the least educated and least affluent groups. Thus, there is a need for effective smoking cessation interventions that reach to, and are effective in this group. Research suggests that modest financial incentives are not very effective in helping smokers quit. What is not known is whether large financial incentives can enhance longer-term (1 year) smoking cessation rates, outside clinical and workplace settings. Trial design A randomized, parallel groups, controlled trial. METHODS: Participants: Eight hundred low-income smokers in Switzerland (the less affluent third of the population, based on fiscal taxation). Intervention: A smoking cessation program including: (a) financial incentives given during 6 months; and (b) Internet-based counseling. Financial rewards will be offered for biochemically verified smoking abstinence after 1, 2, and 3 weeks and 1, 3, and 6 months, for a maximum of 1,500 CHF (1,250 EUR, 1,600 USD) for those abstinent at all time-points. All participants, including controls, will receive Internet-based, individually-tailored, smoking cessation counseling and self-help booklets, but there will be no in-person or telephone counseling, and participants will not receive medications. The control group will not receive financial incentives. OBJECTIVE: To increase smoking cessation rates. Outcome: Smoking abstinence after 6 and 18 months, not contradicted by biochemical tests. We will assess relapse after the end of the intervention, to test whether 6-month effects translate into sustained abstinence 12 months after the incentives are withdrawn.Randomization: Will be done using sealed envelopes drawn by participants. Blinding: Is not possible in this context. DISCUSSION: Smoking prevention policies and interventions have been least effective in the least educated, low-income groups. Combining financial incentives and Internet-based counseling is an innovative approach that, if proven acceptable and effective, could be later implemented on a large scale at a reasonable cost, decrease health disparities, and save many lives.

Effectiveness of health checks conducted by nurses in primary care: results of the OXCHECK study after one year. Imperial Cancer Research Fund OXCHECK Study Group.

OBJECTIVE--To assess the effectiveness of health checks by nurses in reducing risk factors for cardiovascular disease in patients from general practice. DESIGN--Randomised controlled trial. SETTING--Five urban general practices in Bedfordshire. SUBJECTS--2136 patients receiving an initial health check in 1989-91 and scheduled to be re-examined one year later in 1990-2 (intervention group); 3988 patients receiving an initial health check in 1990-2 (control group). All patients were aged 35-64 years at recruitment in 1989. MAIN OUTCOME MEASURES--Serum total cholesterol concentration, blood pressure, body mass index, confirmed smoking cessation. RESULTS--Mean serum total cholesterol was 2.3% lower in the intervention group than in the controls (difference 0.14 mmol/l (95% confidence interval 0.08 to 0.20)); the difference was greater in women (3.2%, P < 0.0001) than men (1.0%, P = 0.18). There was no significant difference in smoking prevalence, quit rates, or body mass index. Systolic and diastolic blood pressure were 2.5% and 2.4% lower respectively in the intervention group. The proportion of patients with diastolic blood pressure > or = 100 mm Hg was 2.6% (55/2131) in the intervention group and 3.4% (137/3987) in the controls (difference 0.9% (0.0 to 1.7)); the proportion with total cholesterol concentration > or = 8 mmol/l 4.8% (100/2068) and 7.6% (295/3905) (difference 2.7% (1.5 to 4.0)); and that with body mass index > or = 30 12.4% (264/2125) and 14.0% (559/3984) (difference 1.6% (-0.2 to 3.4)). CONCLUSIONS--General health checks by nurses are ineffective in helping smokers to stop smoking, but they help patients to modify their diet and total cholesterol concentration. The public health importance of this dietary change depends on whether it is sustained.     

Focus: Addiction: Smoking Use and Cessation Among People with Serious Mental Illness

Smoking rates in people with serious mental illness (SMI) are disproportionately high compared to the general population. It is a leading contributor to the early mortality in this population. Smoking cessation rates are low in this group, though patients are motivated to quit. Unfortunately, health care providers do not always prioritize smoking cessation for this population. This review provides an overview of prevalence rates, biological effects that maintain smoking, and evidence-based treatments for smoking cessation in SMI. In addition, objective and qualitative data from a chart review of 78 patients with SMI prescribed smoking cessation treatment at one community mental health center are described. Of these, 30 (38.5 percent) were found to either quit (16/78) or reduce (14/78) smoking. Varenicline appeared to be particularly effective. Review of the literature and results of this study suggest that smoking cessation pharmacotherapies are effective for SMI patients and should be offered to those who smoke.     

Effectiveness of the diabetes education and self management for ongoing and newly diagnosed (DESMOND) programme for people with newly diagnosed type 2 diabetes: cluster randomised controlled trial

Objective To evaluate the effectiveness of a structured group education programme on biomedical, psychosocial, and lifestyle measures in people with newly diagnosed type 2 diabetes.Design Multicentre cluster randomised controlled trial in primary care with randomisation at practice level.Setting 207 general practices in 13 primary care sites in the United Kingdom.Participants 824 adults (55% men, mean age 59.5 years).Intervention A structured group education programme for six hours delivered in the community by two trained healthcare professional educators compared with usual care.Main outcome measures Haemoglobin A_1c levels, blood pressure, weight, blood lipid levels, smoking status, physical activity, quality of life, beliefs about illness, depression, and emotional impact of diabetes at baseline and up to 12 months.Main results Haemoglobin A_1c levels at 12 months had decreased by 1.49% in the intervention group compared with 1.21% in the control group. After adjusting for baseline and cluster, the difference was not significant: 0.05% (95% confidence interval −0.10% to 0.20%). The intervention group showed a greater weight loss: −2.98 kg (95% confidence interval −3.54 to −2.41) compared with 1.86 kg (−2.44 to −1.28), P=0.027 at 12 months. The odds of not smoking were 3.56 (95% confidence interval 1.11 to 11.45), P=0.033 higher in the intervention group at 12 months. The intervention group showed significantly greater changes in illness belief scores (P=0.001); directions of change were positive indicating greater understanding of diabetes. The intervention group had a lower depression score at 12 months: mean difference was −0.50 (95% confidence interval −0.96 to −0.04); P=0.032. A positive association was found between change in perceived personal responsibility and weight loss at 12 months (β=0.12; P=0.008).Conclusion A structured group education programme for patients with newly diagnosed type 2 diabetes resulted in greater improvements in weight loss and smoking cessation and positive improvements in beliefs about illness but no difference in haemoglobin A_1c levels up to 12 months after diagnosis.Trial registration Current Controlled Trials ISRCTN17844016.     

Is telephone counselling a useful addition to physician advice and nicotine replacement therapy in helping patients to stop smoking? A randomized controlled trial

BACKGROUND: The authors evaluated the incremental efficacy of telephone counselling by a nurse in addition to physician advice and nicotine replacement therapy in helping patients to stop smoking. METHODS: The trial was conducted at the University of Ottawa Heart Institute. A total of 396 volunteers who smoked 15 or more cigarettes daily were randomly assigned to either of 2 groups: usual care (control group) and usual care plus telephone counselling (intervention group); the groups were stratified by sex and degree of nicotine dependence. Usual care involved the receipt of physician advice on 3 occasions, self-help materials and 12 weeks of nicotine replacement therapy. Telephone counselling was provided by a nurse at 2, 6 and 13 weeks after the target quit date. Point-prevalent quit rates were determined at 52 weeks after the target quit date. RESULTS: The point-prevalent quit rates at 52 weeks did not differ significantly between the control and intervention groups (24.1% v. 23.4% respectively). The quit rates did not differ significantly at the secondary measurement points of 4, 12 and 26 weeks. INTERPRETATION: Brief physician assistance, along with nicotine replacement therapy, can help well-motivated smokers to quit. Three additional sessions of telephone counselling by a nurse were ineffective in increasing quit rates. This form of assistance may be useful in the absence of physician advice or when self-selected by patients.     

Efficacy of genotype notification to Japanese smokers on smoking cessation—An intervention study at workplace

Objectives: It is well-known that smoking causes many diseases including cancers. Informing smokers of their genotypes associated with the vulnerability to the harms of smoking may be effective measures for smoking cessation. The present study examined the effects of genotype notification of an oncogene (L-myc) genotype to smokers on their behavior to quit smoking. Methods: Subjects were 562 employees of a bank who answered to be a smoker for a questionnaire used at annual health checkup at workplace from July to December 2002. Those enrolled on August, October, and December were allocated into the genotype notification group (intervention group), and the rest into the controls. Among 286 smokers allocated into the intervention group, 257 participants (89.9%) agreed to genotype testing. One year after the enrollment, a follow-up questionnaire survey was conducted for all smokers including controls. Results: Those who stated to have quitted smoking were 22 (8.0%) among the 276 controls and 15 (5.8%) among the 257 genotype notified participants, providing that the odds ratio (OR) of cessation for the intervention was 0.64 (95% confidence interval, 0.32–1.28). No psychological problems associated with genotype notification were observed. Conclusion: The present study did not show positive effects of genotype notification on smoking cessation rate. To elevate the cessation rate, methods to explain and notify genotypes should be improved.     

Nortriptyline plus nicotine replacement versus placebo plus nicotine replacement for smoking cessation: pragmatic randomised controlled trial

Objective To test the efficacy of nortriptyline plus nicotine replacement therapy compared with placebo plus nicotine replacement therapy for smoking cessation.Design Pragmatic randomised controlled trial.Setting National Health Service stop smoking service clinics.Participants 901 people trying to stop smoking.Interventions Participants chose their nicotine replacement product, including combinations of nicotine replacement therapy, and received behavioural support. Nortriptyline was started one to two weeks before quit day, with the dose increased from 25 mg to 75 mg daily for eight weeks and reduced if not tolerated.Main outcome measures Primary outcome was prolonged confirmed abstinence at six months. Secondary outcomes were prolonged abstinence at 12 months, drug use, severity of side effects, nicotine withdrawal symptoms, and urges to smoke.Results 72 of 445 (16%) people using nortriptyline and 55 of 456 (12%) using placebo achieved prolonged abstinence at six months (relative risk 1.34, 95% confidence interval 0.97 to 1.86). At 12 months the corresponding values were 49 (11%) for nortriptyline and 40 (9%) for placebo (1.26, 0.84 to 1.87). 337 (79%) people in the nortriptyline arm and 325 (75%) in the placebo arm were taking combination treatment on quit day, median 75 mg per day in both groups. More people in the nortriptyline arm than in the placebo arm took lower doses. The nortriptyline arm had noticeably higher severity ratings for dry mouth and constipation than the placebo arm, with slightly higher ratings for sweating and feeling shaky. Both groups had similar urges to smoke, but nortriptyline reduced depression and anxiety. Overall, withdrawal symptom scores did not differ.Conclusions Nortriptyline and nicotine replacement therapy are both effective for smoking cessation but the effect of the combination is less than either alone and evidence is lacking that combination treatment is more effective than either alone.Trial registration Current Controlled Trials ISRCTN57852484.     

Country profile: Australia,New South Wales. From validation to implementation: Progressing tobacco smoking cessation among people with cancer and beyond via relevant authorities

This paper delineates how a program of tobacco smoking cessation after a cancer diagnosis was achieved by engagement of multiple stakeholders, government, and non-government authorities in one jurisdiction in Australia, New South Wales. While it had become increasingly obvious that smoking cessation imparts benefits akin to other known treatment modalities, knowledge of this generalisation is without benefit unless this information is delivered in a trusted context and means to quit are made available. Against a backdrop of little enthusiasm among clinicians, the Cancer Institute NSW, charged with implementing tobacco control strategies, decided to focus its 2017 annual colloquium on the topic. While the evidence was unequivocal, better clarity was needed that this was indeed a clinical responsibility, and on the resources needed. The Clinical Oncology Society of Australia, (COSA) a non-governmental peak national body representing cancer care professionals, addressed this challenge. The society’s governing body resolved to develop a position statement indicating how smoking cessation might be integrated within hospital-based cancer care. The position statement, endorsed by nineteen other cancer and non-cancer organisations, provided reassurance to the Institute to improve record capture of hospital smoking information; upskill all clinical staff and develop an automatic “patient opt out” referral to existing resources such as the Quitline. Early pilot work shows that people newly diagnosed with cancer who smoke and who were advised at that time to quit increased from 55% in 2016 to 72% in 2019.     

Open randomised trial of intermittent very low energy diet together with nicotine gum for stopping smoking in women who gained weight in previous attempts to quit

ObjectiveTo determine whether attempts to prevent weight gain will increase success rates for stopping smoking.Design16 week, open, randomised study with 1 year follow up.SettingObesity unit.Subjects287 female smokers who had quit smoking before but started again because of weight concerns.InterventionCombination of a standard smoking cessation programme with nicotine gum and a behavioural weight control programme including a very low energy diet. A control group was treated with the identical programme but without the diet.ResultsAfter 16 weeks, 68/137 (50%) women had stopped smoking in the diet group versus 53/150 (35%) in the control group (P=0.01). Among these women, weight fell by mean 2.1 (95% confidence interval 2.9 to 1.3) kg in the diet group but increased by 1.6 (0.9 to 2.3) kg in the control group (P<0.001). After 1 year the success rates in the diet and control groups were 38/137 (28%) and 24/150 (16%) respectively (P<0.05), but there was no statistical difference in weight gain.ConclusionsCombining the smoking cessation programme with an intervention to control weight helped women to stop smoking and control weight.     

A decade of diabetes: keeping children out of hospital.

OBJECTIVES--To document the number of children aged less than 15 years who developed diabetes and were managed within one large health district, and to evaluate the outcome of those children managed without hospital admission at diagnosis. DESIGN--A retrospective study over 1979-88, when a paediatrician and a physician with special interests in childhood diabetes initiated joint clinics. Data collected from the district diabetes register and files of consultants and health visitors specialising in diabetes. SETTING--Referral of children to consultants in Leicestershire (total population 863,000). MAIN OUTCOME MEASURES--The proportion of children managed without hospital admission, comparison of readmission rates and glycated haemoglobin concentrations between children admitted and those not admitted. RESULTS--Over 10 years 236 children aged 10-14 years developed diabetes (annual incidence rate 12.8/100,000 child population (95% confidence interval 11.3 to 14.7)). In total 138 were not admitted to hospital but received supervised management based at home. Admitted children were younger or acidotic or their family doctors did not contact the diabetes team. Duration of admission declined from seven days in 1979-80 to three days in 1987-8. Ninety two were not admitted to hospital during the 10 years for any reason. Significantly fewer children who received management at home were readmitted for reasons related to diabetes than the group treated in hospital (30 (22%) v 40 (41%); p = 0.004). Concentrations of glycated haemoglobin were no different between the two groups. CONCLUSIONS--Children with newly diagnosed diabetes may be safely and effectively managed out of hospital. Domiciliary or community based management depends on the commitment of consultants specialising in diabetes working in close cooperation with general practitioners, specialist nurses in diabetes, and dietitians.     

Incidence and Variation of Discrepancies in Recording Chronic Conditions in Australian Hospital Administrative Data

Diagnostic data routinely collected for hospital admitted patients and used for case-mix adjustment in care provider comparisons and reimbursement are prone to biases. We aim to measure discrepancies, variations and associated factors in recorded chronic morbidities for hospital admitted patients in New South Wales (NSW), Australia. Of all admissions between July 2010 and June 2014 in all NSW public and private acute hospitals, admissions with over 24 hours stay and one or more of the chronic conditions of diabetes, smoking, hepatitis, HIV, and hypertension were included. The incidence of a non-recorded chronic condition in an admission occurring after the first admission with a recorded chronic condition (index admission) was considered as a discrepancy. Poisson models were employed to (i) derive adjusted discrepancy incidence rates (IR) and rate ratios (IRR) accounting for patient, admission, comorbidity and hospital characteristics and (ii) quantify variation in rates among hospitals. The discrepancy incidence rate was highest for hypertension (51% of 262,664 admissions), followed by hepatitis (37% of 12,107), smoking (33% of 548,965), HIV (27% of 1500) and diabetes (19% of 228,687). Adjusted rates for all conditions declined over the four-year period; with the sharpest drop of over 80% for diabetes (47.7% in 2010 vs. 7.3% in 2014), and 20% to 55% for the other conditions. Discrepancies were more common in private hospitals and smaller public hospitals. Inter-hospital differences were responsible for 1% (HIV) to 9.4% (smoking) of variation in adjusted discrepancy incidences, with an increasing trend for diabetes and HIV. Chronic conditions are recorded inconsistently in hospital administrative datasets, and hospitals contribute to the discrepancies. Adjustment for patterns and stratification in risk adjustments; and furthermore longitudinal accumulation of clinical data at patient level, refinement of clinical coding systems and standardisation of comorbidity recording across hospitals would enhance accuracy of datasets and validity of case-mix adjustment.     

Sex differences in case fatality before and after admission to hospital after acute cardiac events: analysis of community based coronary heart disease register.

OBJECTIVE: To determine whether the reported higher case fatality in hospital after an acute cardiac event in women can be explained by sex differences in mortality before admission and in baseline risk factors. DESIGN: Analyses of data from a community based coronary heart disease register. SETTING: Auckland region, New Zealand. SUBJECTS: 5106 patients aged 25-64 years with an acute cardiac event leading to coronary death or definite myocardial infarction within 28 days of onset, occurring between 1986 and 1992. MAIN OUTCOME MEASURES: Case fatality before admission, 28 day case fatality for patients in hospital, and total case fatality after an acute cardiac event. RESULTS: Despite a more unfavourable risk profile women tended to have lower case fatality before admission than men (crude odds ratio 0.88; 95% confidence interval 0.77 to 1.02). Adjustment for age, living arrangements, smoking, medical history, and treatment increased the effect of sex (0.72; 0.60 to 0.86). After admission to hospital, women had a higher case fatality than men (1.76; 1.43 to 2.17), but after adjustment for confounders this was reduced to 1.18 (0.89 to 1.58). Total case fatality 28 days after an acute cardiac event showed no significant difference between men and women (0.85; 0.70 to 1.02) CONCLUSIONS: The higher case fatality after an acute cardiac event in women admitted to hospital is largely explained by differences in living status, history, and medical treatment and is balanced by a lower case fatality before admission.     

Reduced in-hospital mortality after improved management of children under 5 years admitted to hospital with malaria: randomised trial

Objective To test whether strict implementation of a standardised protocol for the management of malaria and provision of a financial incentive for health workers reduced mortality.Design Randomised controlled intervention trial.Setting Paediatric ward at the national hospital in Guinea-Bissau. All children admitted to hospital with severe malaria received free drug kits.Participants 951 children aged 3 months to 5 years admitted to hospital with a diagnosis of malaria randomised to normal or intervention wards.Interventions Before the start of the study, all personnel were trained in the use of the standardised guidelines for the management of malaria, including strict follow-up procedures. Nurses and doctors were randomised to work on intervention or control wards. Personnel in the intervention ward received a small financial incentive ($50 (£25; €35)/month for nurses and $160 for doctors) and their compliance with standard case management was closely monitored.Main outcome measures In-hospital mortality and cumulative mortality within 4 weeks of hospital admission.Results In-hospital mortality was 5% for the intervention group and 10% in the control group (risk ratio 0.48, 95% confidence interval 0.29 to 0.79). The effect may have been stronger in patients with positive malaria slides (0.36, 0.16 to 0.80). Cumulative mortality 4 weeks after discharge was also lower in the intervention group (0.61, 0.40 to 0.95).Conclusions Supervising healthcare workers to adhere to a standardised treatment protocol was associated with greatly reduced in-hospital mortality. Financial incentives may be important for the dedication and compliance of staff members.Trial registration Clinical Trials {"type":"clinical-trial","attrs":{"text":"NCT00465777","term_id":"NCT00465777"}}NCT00465777.
