[Patterns of contact with general practice in the daytime by guest workers with immigrant and refugee background in Copenhagen municipality, 1998].

INTRODUCTION: Little is known about immigrants' contact with the Danish health system. The aim of this study was to compare the pattern of contact with general practitioners of guest workers, refugees and non-immigrants in Copenhagen. MATERIALS AND METHODS: 2.04 daytime contacts (home visits, clinic consultations and telephone consultations) by 423,202 inhabitants during the year 1998 as recorded in the National Patient Registry were merged with information about citizenship and place of birth in the Danish Central Office of Civil Registration. The contacts were described by the average number of contacts per person at risk per year. The differences between non-immigrants and immigrants were analyzed using Poisson regression. RESULTS: Immigrants and non-immigrants showed nearly the same sex- and age-dependent contact pattern. Immigrant children (1-18 years) and older people (60+ years) had a lower contact rate than non-immigrants in the same age groups. The 19- to 59-year-old guest worker women and men had 3% and 5% higher contact rates and the refugee women and men 2% and 17% higher contact rates, respectively, than non-immigrants in the same age group. The percentage of telephone consultations was lower for immigrants and the clinic consultation rate higher than for non-immigrants. CONCLUSION: There are sex- and age-specific differences between immigrants and non-immigrants. If equity is a goal in public health care, we should know more about its actual use. More complex research designs are needed, as well as theoretical studies, to shed light on these issues.

[Patterns of contact with the out-of-hours service and emergency rooms by guest workers with immigrant and refugee background in Copenhagen municipality, 1998].

INTRODUCTION: Outside normal office hours, patients in Denmark with acute conditions are treated by the out-of-hours service connected to general practice and in the emergency rooms of hospitals. Little is known about the contact pattern of immigrants with these services. The purpose of this study was to compare the contact rates for immigrants (guest workers and refugees) and non-immigrants with out-of-hours service and emergency rooms and compare the results with the total number of contacts with general practice (out-of-hours service, daytime contacts) and emergency rooms. MATERIALS AND METHOD: Data from 2,243,633 contacts in Copenhagen 1998 registered in the National Patient Registry and 112,733 visits to emergency units were merged with information about citizenship and place of birth in the Central Office of Civil Registration. The contacts were described by the average number of contacts per person at risk per year. RESULTS: The contact rates with the out-of-hours service were significantly lower for immigrant children than for non-immigrants, whereas the number of visits to emergency rooms did not show any differences. For both sexes aged 19-59, the contact rates for out-of-hours service and emergency rooms were higher for immigrants. The total number of contacts was 31-11% lower for children and those 60+ years of age and 4-20% higher for 19- to 59-year-old immigrants. CONCLUSION: Significant differences in the use of acute services by immigrants and non-immigrants were observed. Whether this is appropriate is questionable.

Individualised treatment goals in diabetes care.

OBJECTIVES: To examine 1) patients' characteristics according to the treatment goal chosen at diabetes diagnosis, and 2) the association between individualised goals for glycated haemoglobin (HbA1c), blood pressure (BP) and lipids, and the risk factor level subsequently achieved. DESIGN: Follow-up study embedded in a multifaceted intervention study directed at doctors encouraging individualised goal-setting in newly diagnosed diabetic patients aged > or = 40 years. SETTING: General practice. SUBJECTS: In all, 243 general practitioners and 674 patients participated. MAIN OUTCOME MEASURES: Risk factors for diabetic complications. RESULTS: Relatively young age, low diagnostic plasma glucose, low BMI, a moderate or high level of physical activity and normoalbuminuria were associated with a treatment goal of good control at diagnosis. After 5 years, median HbA1c was 8.2%, 8.6% and 8.0% in patients with a goal of good, acceptable and poor control, respectively. Patients with a goal of good control versus those with a goal of acceptable control had a lower HbA1c level in a regression analysis adjusted for age, sex, HbA1c at diagnosis, BMI, total cholesterol, fasting triglycerides, BP, physical activity, smoking status and diabetes duration. We found no association between goals and the level of BP and lipids. CONCLUSION: Doctors tend to pursue normoglycaemia in relatively young patients with low blood glucose, low BMI, high activity level and normoalbuminuria. Patients for whom a goal of normoglycaemia was chosen at diagnosis achieved favourable glycaemic control at 5-year follow-up. Whether doctors choosing the goals were good at predicting future glycaemic control, or whether goal-setting is an important motivational factor in achieving optimal glycaemic control needs to be explored.

Doctors' characteristics do not predict long-term glycaemic control in type 2 diabetic patients.

Glycaemic control in type 2 diabetic patients varies widely between general practitioners (GPs). To increase our understanding of this variation, linear random effects models were used to examine the predictive value of GP characteristics on the course of annual HbA1c measurements, in 688 newly diagnosed type 2 diabetic patients between one and five years after diabetes diagnosis. We found that characteristics of centrally supported GPs, such as interest in diabetes, experience, practice type, list size, and weekly working hours, did not predict their patients' glycaemic control.
