Objective To assess the effects of a multifaceted educational intervention in Norwegian general practice aiming to reduce antibiotic prescription rates for acute respiratory tract infections and to reduce the use of broad spectrum antibiotics.Design Cluster randomised controlled study.Setting Existing continuing medical education groups were recruited and randomised to intervention or control.Participants 79 groups, comprising 382 general practitioners, completed the interventions and data extractions.Interventions The intervention groups had two visits by peer academic detailers, the first presenting the national clinical guidelines for antibiotic use and recent research evidence on acute respiratory tract infections, the second based on feedback reports on each general practitioner’s antibiotic prescribing profile from the preceding year. Regional one day seminars were arranged as a supplement. The control arm received a different intervention targeting prescribing practice for older patients.Main outcome measures Prescription rates and proportion of non-penicillin V antibiotics prescribed at the group level before and after the intervention, compared with corresponding data from the controls.Results In an adjusted, multilevel model, the effect of the intervention on the 39 intervention groups (183 general practitioners) was a reduction (odds ratio 0.72, 95% confidence interval 0.61 to 0.84) in prescribing of antibiotics for acute respiratory tract infections compared with the controls (40 continuing medical education groups with 199 general practitioners). A corresponding reduction was seen in the odds (0.64, 0.49 to 0.82) for prescribing a non-penicillin V antibiotic when an antibiotic was issued. Prescriptions per 1000 listed patients increased from 80.3 to 84.6 in the intervention arm and from 80.9 to 89.0 in the control arm, but this reflects a greater incidence of infections (particularly pneumonia) that needed treating in the intervention arm.Conclusions The intervention led to improved antibiotic prescribing for respiratory tract infections in a representative sample of Norwegian general practitioners, and the courses were feasible to the general practitioners.Trial registration Clinical trials NCT00272155.

Objectives: To compare ethnic and gender differences in generalized and central obesity and to investigate whether these differences persisted after adjusting for socio-demographic and lifestyle factors. Design: In 2002, the population-based cross-sectional, Oslo Immigrant Health study was conducted. Subjects: A total of 7890 Oslo residents, born between 1942 and 1971 in Turkey, Iran, Pakistan, Sri Lanka and Vietnam, were invited and 3019 attended. Measurements: Participants completed a health questionnaire and attended a clinical screening that included height, weight, waist and hip measurements. Results: Generalized obesity (BMIX30 kg/m 2 ) was greatest among women from Turkey (51.0%) and least among men from Vietnam (2.7%). The highest proportions of central obesity (waist hip ratio (WHR)X0.85) were observed among women from Sri Lanka (54.3%) and Pakistan (52.4%). For any given value of BMI, Sri Lankans and Pakistanis had higher WHR compared to the other groups. Despite a high mean BMI, Turkish men (27.9 kg/m 2 ) and women (30.7 kg/m 2 ) did not have a corresponding high WHR. Ethnic differences in BMI, waist circumference and WHR persisted despite adjusting for socio-demographic and lifestyle factors. Conclusion: We found large differences in generalized and central obesity between immigrant groups from developing countries. Our data find high proportions of overweight and obese subjects from Pakistan and Turkey, but low proportions among those from Vietnam. Subjects from Sri Lanka and Pakistan had the highest WHR for any given value of BMI. Our findings, in light of the burgeoning obesity epidemic, warrant close monitoring of these groups.

ARTIs are frequently treated with antibiotics and often with broader spectrum agents than pcV, which is the recommended first-line antibiotic in the Norwegian guidelines. GPs with a high practice activity are, in general, more liberal with respect to the prescription of antibiotics for ARTIs, and the higher the antibiotic prescription rate, the larger the share of non-pcV agents.

BackgroundCo-infection with falciparum malaria and HIV-1 increases the severity and mortality of both infections in unstable malaria-transmission areas. In contrast, in stable transmission areas, HIV co-infection increases the severity of both infections but has not been found to influence malaria mortality.MethodsIn a prospective cross-sectional study, clinical and laboratory data were consecutively collected for all adults admitted with fever and/or suspected malaria to the medical department of the Central Hospital of Maputo, Mozambique, during two malaria seasons from January 2011. Malaria and HIV PCRs were performed, and risk factors for fatal outcomes were analysed. The impact of HIV on the clinical presentation and mortality of malaria was assessed.FindingsA total of 212 non-pregnant adults with fever and/or suspected malaria and 56 healthy controls were included in the study. Of the 131 patients with confirmed falciparum malaria, 70 were co-infected with HIV-1. The in-hospital mortality of the co-infected patients was 13.0% (9/69) compared with 1.7% (1/59) in the patients without HIV (p = 0.018). Malaria severity (p = 0.016) and co-infection with HIV (p = 0.064) were independent risk factors for death although the association with HIV did not reach statistical significance. The co-infected patients had significantly more frequent respiratory distress, bleeding disturbances, hypoglycaemia, liver and renal failure and high malaria parasitemia compared with the patients with malaria alone.InterpretationsHIV co-infection is associated with increased disease severity in and mortality from malaria in an area of stable malaria transmission. This finding was not observed earlier and should motivate doctors working in malaria-endemic areas to consider early HIV testing and a closer follow-up of patients with malaria and HIV co-infection.

BackgroundOlder patients are at particular risk for adverse drug reactions. In older people, interventions targeting potentially inappropriate prescriptions (PIPs) are considered important measures to minimise drug-related harm, especially in the general practice setting where most prescriptions for older patients are issued. AimTo study the effects of a multifaceted educational intervention on GPs' PIPs for older patients. Design and settingThis was a cluster randomised, educational intervention study in Norwegian general practice. Pre-study data were captured from January 2005 MethodEighty continuing medical education (CME) groups (465 GPs) were randomised to receive the educational intervention on GPs' PIPs for older patients (41 CME groups; 256 GPs) or another educational intervention (39 CME groups; 209 GPs); these two groups acted as controls for each other. GPs' prescription data from before and after the intervention were assessed against a list of 13 explicit PIP criteria for patients aged ≥70 years. In the CME groups, trained GPs carried out an educational programme, including an audit, focusing on the 13 criteria and their rationale. ResultsA total of 449 GPs (96.6%) completed the study; 250 in the intervention group and 199 in the control group. After adjusting for baseline differences and clustering effects, a reduction relative to baseline of 10.3% (95% confidence interval = 5.9 to 15.0) PIPs per 100 patients aged ≥70 years was obtained. ConclusionEducational outreach visits with feedback and audit, using GPs as academic detailers in GPs' CME groups, reduced PIPs for older patients aged ≥70 years in general practice.
