Objectives: To analyse whether there is a relation-ship between birth weight and cardiovascular risk factors given the influence of potential modifying factors from birth time, former generations and adult life.Design: Population-based cohort followed until 80 years of age.Setting: Sweden.Subjects: A total of 478 singleton men born in 1913 and participating in a population study in Gothenburg, Sweden, from age 50.Main Outcome Measures: Systolic blood pressure (SBP), antihypertensive treatment, incident diabetes mellitus, and serum total cholesterol, serum triglycerides and waist circumference as both continuous variables and in the highest quintiles of their distributions.Results: After adjustment for the influence of birth time variables, hereditary factors and anthropometric and socio-economic adult life variables, SBP decreased by 3.7 mmHg per 1000 g increase of birth weight, the prevalence of antihypertensive treatment decreased by 32%, diabetes decreased by 53%, serum total cholesterol decreased by 0.20 mmol L(-1) and being in the top quintile of serum cholesterol decreased by 23%. The population risk percentage due to a birth weight < or =3000 g was for all three outcomes 3.8% and for antihypertensive treatment, diabetes and cholesterol 0.2, 18 and 2.5%, respectively.Conclusions: Low birth weight thus seems to affect the development of increasing SBP, antihypertensive treatment, diabetes and high cholesterol even when potential effect modifiers from birth time, former generations and adult life were taken into account. In the general population, the risk percentage due to a birth weight < or =3000 g was largest for diabetes. [ABSTRACT FROM AUTHOR]

Background: Valuable evaluations of the quality of drug prescribing in routine health care are difficult to perform. It is even more difficult to study prescribing in a non-gatekeeping healthcare system with a variety of caregivers involved in patient care. Consequently, there is a need to develop methods for evaluation using data available in routine health care. Objectives: The aim of this study was to analyse possibilities and limitations for evaluation of the quality of drug prescribing using routinely collected aggregate data on dispensed drugs and health care provision. A secondary aim was to study the effects of allocating more resources to primary health care (PHC) on the quality of drug prescribing. Methods: The study was performed with routinely collected data from 10 PHC centres in Stockholm, Sweden that were participating in an intervention project that aimed to decrease the number of inhabitants per PHC doctor. Time periods for analysis were October-December 1999, 2000 and 2001. Data on dispensed prescriptions were analysed by age using Anatomical Therapeutic Chemical (ATC) classification/defined daily dose (DDD) methodology. The general quality of prescribing was determined using DU90% methodology (identifying the number of drugs constituting 90% of the volume expressed in DDDs and the adherence to evidence-based recommendations) and ratios between different treatment alternatives. The total volume and cost of drugs prescribed to the population was also analysed. Results: In 2001, PHC centres accounted for, on average, 27% (range 14-36%) of all doctor consultations and 32% (range 22-43%) of all prescriptions to populations in the corresponding primary care districts. There was great variation between the different PHC centres with regard to the prescribing doctors' compliance with guidelines from the regional drug and therapeutics committee, and the utilization of health care and drugs among the population in the corresponding primary care districts. No clear improvement was observed over time. Conclusion: Analysis of aggregated prescription and healthcare data at population level was feasible. However, the effects of allocation of increasing resources to PHC on the quality of drug prescribing need to be analysed in a broader context. [ABSTRACT FROM AUTHOR]

BACKGROUND: The incidence of cutaneous malignant melanoma has increased rapidly in Sweden during the last 20 years. One way of reducing mortality is through early diagnosis. The aim of this study was to explore the reasons why different people seek medical attention for pigmented skin lesions, using a qualitative approach. METHODS: Three groups of laymen (N=90), all with varying experience of pigmented skin lesions, were interviewed. RESULTS: Most of the respondents had sought medical attention primarily because they were worried about a specific skin lesion. Patients with melanoma mentioned concern about very dark skin lesions more often than other respondents did. Encouragement by family and friends was also important. CONCLUSION: Very dark coloration in pigmented skin lesions might be added to public recommendations for early discovery of melanoma. No other new nonmedical feature or circumstance was identified when the results were compared with two established systems for clinical diagnosis of melanoma (the ABCD criteria and the seven-point checklist).

Background: Irritable bowel syndrome (IBS) is commonly thought to be associated with psychologic distress. However, in some studies only persons who had sought medical care for IBS (IBS patients) showed an increased frequency of psychiatric symptoms, and nonpatients did not differ significantly from normal subjects. Our aims were 1) to estimate the prevalence of IBS in the population aged 18-45 years, 2) to find the proportion seeking medical care for IBS, and 3) to compare IBS subjects with normals, and IBS patients with IBS nonpatients with regard to mental health. Methods: Questionnaires on IBS symptoms and the General Health Questionnaire (GHQ) were mailed to 5000 randomly sampled persons aged 18-45 years. The response rate was 58%. Results: IBS was found in 7.4% of the men and 13.3% of the women. Those who had sought medical attention had more severe symptoms. The Likert mean score on the GHQ was 4.7 (95% confidence interval, 4.4-5.0) points higher for the IBS group than for normals (P < 0.001). There was no difference in GHQ scores between IBS patients and nonpatients. Conclusions: The results indicate that IBS per se is associated with more psychiatric distress, regardless of medical care-seeking. Seeking medical care is associated with more severe IBS symptoms.

This study examines the extent to which people forego seeking primary health care due to the cost and to investigate the associated demographic, physical, psychological and social factors. In 1995, questionnaires were sent to a random sample of the population in two healthcare regions in the Stockholm area in Sweden covering a total of about 400,000 inhabitants. Among the sample of 8200 people over the age of 17 yr, 69% replied to the questionnaire. About 22% stated that on one or more occasions during the past year they had foregone seeking care due to the cost. About 30% stated that they had foregone or hesitated seeking medical help due to the cost during the past year. This applied to women to a greater extent than men. Not seeking medical care was strongly correlated to a self-assessment of personal finances. Among those who described their financial situation as poor, more than half stated that, on at least one occasion, they had foregone seeking medical care due to the cost. As a consequence, weaker groups in society such as the unemployed, students, foreign nationals and single mothers were overrepresented in this group. Those who had foregone care perceive their health as worse and they had a greater degree of general pains and a higher occurrence of chronic disease/disability compared to those who had not foregone care. Between 1970 and 1995, patient charges for consulting a general practitioner within Stockholm County have increased more than three times faster than the consumer price index. The results suggest that the rapidly increasing patient charges particularly affect the weaker social groups and thus pose a threat to the aim of Swedish healthcare legislation--that good care should be available to everyone on equal terms.

Background: Warfarin is used for the prevention of stroke in chronic atrial fibrillation. The product has a narrow therapeutic index and to obtain treatment success, patients must be maintained within a given therapeutic range (International Normalised Ratio;INR). To ensure a wise allocation of health care resources, scrutiny of costs associated with various treatments is justified. The objective of this study was to estimate the health care cost of INR controls in patients on warfarin treatment with chronic atrial fibrillation in primary care in Sweden.Methods: Data from various sources were applied in the analysis. Resource consumption was derived from two observational studies based on electronic patient records and two Delphi-panel studies performed in two and three rounds, respectively. Unit costs were taken from official databases and primary health care centres.Results: The mean cost of one INR control was SEK 550. The mean costs of INR controls during the first three months, the first year and during the second year of treatment were SEK 6,8111, SEK 16,244 and SEK 8,904 respectively.Conclusion: INR controls of patients on warfarin treatment in primary care in Sweden represent a substantial cost to the health care provider and they are particularly costly when undertaken in home care. The cost may however be off-set by the reduced incidence of stroke. [ABSTRACT FROM AUTHOR]

BACKGROUND: Self-rated health is an important indicator of quality of life as well as a good predictor of future health. The purpose of the study was to follow up the self-rated health and the prevalence of symptoms of depression and general symptoms in a population of first-ever stroke patients 3 and 12 months after stroke. METHODS: All patients surviving their first-ever stroke and residing in Nacka municipality in Stockholm County Council were included using a multiple overlapping search strategy during an 18-month period (n = 187). Our study group comprised the 145 patients who survived the first 3 months after stroke. Three and 12 months after their stroke, the patients were assessed regarding self-rated health and general symptoms using parts of the Göteborg Quality of Life Instrument (GQLI), and regarding symptoms of depression using the Montgomery Asberg Depression Scale (MADRS-S). RESULTS: Self-rated health was rated as very good or rather good by 62% at 3 months after stroke and by 78% at 12 months after stroke. More than half of the patients suffered from symptoms of depression, with no significant improvement at 12 months. The most common general symptoms at 3 months after stroke were fatigue, sadness, pain in the legs, dizziness and irritability. Fatigue and sadness were still common at 12 months. Twelve months after stroke the prevalences of crying easily, irritability, impaired concentration, nausea and loss of weight were significantly lower. CONCLUSION: The majority of patients rated their health as rather good or very good at 3 and 12 months after stroke. However, the majority suffered from fatigue and from symptoms of depression after both 3 and 12 months. In continued care of stroke survivors, it is important to consider the fact that many patients who rate their health as good may nevertheless have symptoms of depression, and some of them may benefit from anti-depressive treatment.

BACKGROUND: Warfarin is used for the prevention and treatment of various thromboembolic complications. It is an efficacious anticoagulant, but it has a narrow therapeutic range, and regular monitoring is required to ensure therapeutic efficacy and at the same time avoid life-threatening adverse events. The objective was to assess management and resource consumption associated with patient monitoring episodes during warfarin treatment in primary health care in Sweden. METHODS: Delphi technique was used to systematically explore attitudes, demands and priorities, and to collect informed judgements related to monitoring of warfarin treatment. Two separate Delphi-panels were performed in three and two rounds, respectively, one concerning tests taken in primary health care centres, involving 34 GPs and 10 registered nurses, and one concerning tests taken in patients' homes, involving 49 district nurses. RESULTS: In the primary health care panel 10 of the 34 GPs regularly collaborated with a registered nurse. Average time for one monitoring episode was estimated to 10.1 minutes for a GP and 21.4 minutes for a nurse, when a nurse assisted a doctor. The average time for monitoring was 17.6 minutes for a GP when not assisted by a nurse. Considering all the monitoring episodes, 11.6% of patient blood samples were taken in the individual patient's home. Average time for such a monitoring episode was estimated to 88.2 minutes. Of all the visits, 8.2% were performed in vain and took on average 44.6 minutes. In both studies, approximately 20 different elements of work concerning management of patients during warfarin treatment were identified. CONCLUSION: Monitoring of patients during treatment with warfarin in primary health care in Sweden involves many elements of work, and demands large resources, especially when tests are taken in the patient's home.

Objective: To illustrate the geographical West-to-East division of coronary heart disease (CHD) by comparing a population from Sweden, that represents a Western country to a population from Estonia, that represents an Eastern country. Estonia has an approximately 2-4-fold higher CHD prevalence for 55-year-old women and men, respectively, than Sweden.Design: Randomized screening of 35- and 55-year-old men and women in Sollentuna county, Sweden and Tartu county, Estonia. Eight hundred subjects, 100 from each cohort, were invited to participate in the study, 272 Swedes and 277 Estonians participated.Setting: Preventive cardiology, administered by a primary health care centre at the Karolinska Hospital, Sweden and a cardiology centre at Tartu University Hospital, Estonia.Main Outcome Measures: The CHD risk factors (smoking, blood pressure, concentrations of lipoproteins, fibrinogen, and glucose) and certain environmental factors and attitudes related to CHD risk by questionnaires (fat-type and alcohol ingestion, self-assessed rating of CHD susceptibility).Results: Of the 55-year-old men, 57% smoked in Estonia and 20% smoked in Sweden. Similar, although less pronounced differences showing higher smoking prevalence, were seen for 35-year-old Estonian men and women, whilst for 55-year-old women, less than 20% smoked in either country. Estonian 55-year-old women had lower HDL cholesterol and higher LDL cholesterol serum concentrations than Swedish 55-year-old women. Estonians reportedly ate food containing more saturated fats than Swedes, as indicated by the scale-score questionnaire. Estonians, relative to Swedes, rated their chance of developing CHD higher, and paradoxically, Estonians did to a much lesser degree believe that life style influences the risk of developing CHD.Conclusions: Elevated smoking prevalence is a striking difference between the Estonian and Swedish populations likely to explain the much higher CHD prevalence in Estonian men. The lower HDL cholesterol and higher LDL cholesterol in Estonian 55-year-old women may explain the higher CHD prevalence in Estonian women. Furthermore, the SWESTONIA CHD study (i.e. comparison between Sweden and Estonia) shows several environmental differences between the countries populations related to fat content in food, alcohol drinking patterns, and views on CHD risk and the importance of lifestyle intervention, that could contribute to the higher CHD prevalence in Estonia.
