Resource use and costs associated with patients treated for depression in primary care.

We investigated medical resource consumption, productivity loss and costs associated with patients treated with antidepressants for depression in primary care in Sweden. Patients on treatment for depression were followed naturalistically for six-months, and data on patients' characteristics, daily activity and resource-use were collected. The total cost per patient was estimated at euro 5,500 (95%CI euro 5,000-6,100) over six months in 2005 prices. Direct costs were estimated at euro 1,900 (euro 1,700-2,200), 35% of total costs, and indirect costs at euro 3,600 (euro 3,100-4,100), 65% of total costs. The cost for antidepressants represented only 4% of the total costs. We conclude that the burden of depression is high, both to the individual as well as to wider society, and there seems to be a particular need for therapies that have the potential to improve productivity in depressed patients.

Using aggregate data on dispensed drugs to evaluate the quality of prescribing in urban primary health care in Sweden.

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.

Birth weight and cardiovascular risk factors in a cohort followed until 80 years of age: the study of men born in 1913.

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.

The impact of birth weight on coronary heart disease morbidity and mortality in a birth cohort followed up for 85 years: a population-based study of men born in 1913.

OBJECTIVES: To analyse whether there is a relationship between birth weight on the one hand and coronary heart disease (CHD) and cardiovascular disease (CVD) mortality and morbidity on the other, whether such a relationship is influenced by potential modifying factors from the time of birth, adult height and the presence of diabetes, and what significance these possible associations might have for the CHD and CVD rates in the general population. DESIGN: Population-based birth cohort. SETTING: Sweden. SUBJECTS: A total of 1319 singleton men born in 1913, surviving until age 20 and from then on followed until 85 years of age. MAIN OUTCOME MEASURES: CHD and CVD mortality and morbidity events. RESULTS: The gestational age adjusted CHD and CVD mortality and morbidity hazard ratios were virtually unaffected by birth weight. Taking possible effect-modifying variables into account did not change the results. The population attributable risk percentage for CHD and CVD mortality and morbidity due to a birth weight <or=3000 g was 1% or less. CONCLUSIONS: Birth weight did not significantly affect CHD or CVD mortality or morbidity. A birth weight <or=3000 g contributes little to the burden of CHD and CVD on a community level.

Psychological factors in irritable bowel syndrome: a population-based study of patients, non-patients and controls.

BACKGROUND: It has been suggested that psychopathology in irritable bowel syndrome (IBS) patients is a function of patient status rather than of the disease. Although there are many studies comparing IBS patients, IBS non-patients, and controls with each other, no previous study has recruited all three groups from a representative community sample and had all subjects diagnosed by a physician. In the present study we aimed to compare psychological factors in IBS patients, IBS non-patients, and normal controls in a sample recruited from the population. METHODS: Subjects aged 18-45 years were recruited from a random sample of the normal population. Seventeen (2 M and 15 F) IBS patients were matched by sex and age with IBS non-patients and normals. Measures of personality traits, interpersonal distress, and temporary psychological distress were used. A physician diagnosed all 51 subjects in order to exclude possible gastrointestinal diagnoses other than IBS. RESULTS: Controls often differed from IBS non-patients and patients on the personality, interpersonal, and psychological distress measures, while IBS non-patients and patients very rarely differed from each other. All three groups were non-alexithymic. CONCLUSIONS: The results indicate that there are psychopathological differences between normals and IBS persons (patients and non-patients), but they could not confirm that psychopathology was a function of patient status. Whether this psychopathology is a vulnerability factor for IBS, or a consequence of it, remains to be studied.

Risk factors for coronary heart disease in 55- and 35-year-old men and women in Sweden and Estonia.

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.

[Interventional therapy after failed fibrinolysis in acute myocardial infarct. Acute and long-term outcome of referral for rescue balloon angioplasty].

BACKGROUND: The results from studies of coronary angioplasty after failed thrombolysis (rescue-PTCA) in acute myocardial infarction are contradictory. Long-term results were not presented till now. Therefore we analyzed the data from our registry of those patients whose acute and long-term results were available. PATIENTS AND METHODS: Data of 49 patients were analyzed who had been admitted for rescue-PTCA from other hospitals. Thrombolysis had to be started < 6 hours (mean 2.7 hours) from onset of symptoms. Rescue-PTCA had to be completed within < 24 hours (mean 10.5 hours). 37 patients received streptokinase, seven rt-PA, three urokinase and two prourokinase. Electrocardiographic and clinical criteria were used to define failure of thrombolysis. The data of the acute results were from a prospective registry and the long-term results came from clinical follow-up visits and a questionnaire sent to the patients. RESULTS: Mean age of the patients was 48.5 years (38-78 years), 45 male, nine patients in cardiogenic shock (18%), infarct related artery (IRA): RCA 22x, LAD 21x, LCX 5x, CABG 1x, single vessel disease 27x, multiple vessel disease 22x. Acute results: Initial IRA-TIMI flow 0 in 28 patients, 1 in twelve patients, 2 in 9 patients; after rescue-PTCA TIMI flow 1 in one patient, 2 in two patients, 3 in 46 patients (procedural success 94%). Hospital mortality 8.2% (four patients), all in cardiogenic shock. Early reocclusion rate 10%. Bleeding complications 14%, no fatal complications. Long-term results: Observation period 2.5 years in 42 patients (0.5-6.5 years). Three more deaths. Total mortality 14% (7/49). Angiographic follow-up: Ejection fraction initially 50%; 53% after 3 months. Repeat revascularization in 43% (15/35): Re-PTCA in 8/35, surgery in 6/35 patients, 1x transplantation. 80% of the patients were free from angina or heart failure. CONCLUSIONS: Rescue-PTCA in acute myocardial infarction has a high procedural success rate with a low hospital mortality. It is the treatment of choice for patients in cardiogenic shock. Transportation to an interventional center is safe. The reintervention rate is comparably high. The long-term results are good.

Questioning questions about symptoms of benign prostatic hyperplasia.

OBJECTIVES: Our aim was to conduct a survey about urinary symptoms and to find out if questioning patients about symptoms is helpful for the GP to make medical decisions concerning prostate problems among middle-aged men. METHODS: Twelve hundred randomly chosen men aged 55--65 years from the general population in north-west Stockholm, Sweden were sent a questionnaire consisting of symptom questions focusing on prostate problems based on the International Prostate Symptom Score (I-PSS). A subset of 120 respondents were asked to answer the same questions again and to participate in a urological examination including urodynamics and ultrasonography. The main outcome measures were the prevalence of urinary symptoms and the relationship between the symptom score and objective measures. RESULTS: A response rate of 86% was obtained in the questionnaire study. Twenty-one per cent of the respondents stated that they had general problems related to urination. Among individual symptoms, post-void dribbling and a weak stream were most common. Among the men examined at the Urological Department, the average prostatic volume was found to be 40 cm(3). Three out of four were assessed to have infravesical obstruction. No correlation between subjective symptoms and objective measurements of either a statistical or clinical significance was found. CONCLUSIONS: Urinary symptoms are common among middle-aged men. Further, an enlarged prostate and/or infravesical obstruction is often found in the ageing man. Information obtained by asking prostate-specific symptom questions cannot, however, serve as the foundation for the GP to find those men whose problems would be solved by actions directed at the prostate.

A population study on irritable bowel syndrome and mental health.

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.

Provision for clinic patients in the ED produces more nonemergency visits.

This study sought to evaluate how the addition of a general practitioner (GP) surgery influences the utilization of an emergency department (ED). An intervention trial with historical control was conducted in a Swedish university hospital ED. A GP surgery was established in the ED by the addition of GP physicians without the addition of other personnel (nurses, secretaries, aids). The number of persons evaluated and managed by the GP physicians and ED physicians were quantified preintervention (April 1992 to October 1993) and postintervention (April 1994 to October 1995). Further information was obtained by questionnaires distributed to all physicians and patients during three sample study weeks: 1 week before intervention and 6 and 18 months after the intervention. Patient volume, percentages of inappropriate visits, and types of services were recorded. The addition of GP physicians increased the number of visits to the ED by 27% (4,694 per month to 5,952 per month). The percentage of patients managed in the ED who had nonurgent complaints (primary health care needs) increased with the intervention from 22% (95% confidence interval [CI] 19%, 25%) to 33% (95% CI 30%, 37%). The increased demand on the ED of patients with nonurgent complaints increased the average waiting time for patients with urgent or emergent complaints from 35 minutes to 40 minutes (14%). The introduction of GPs to an ED increased the number and proportion of patients presenting to the ED with nonurgent complaints.

Self-report as a selection instrument in screening for cardiovascular disease risk.

INTRODUCTION: Cardiovascular disease (CVD) risk screening may rely partly on self-report information. The accuracy of self-reporting in relation to the actual risk factor status is insufficiently known. DESIGN: Self-report (yes, no, don't know) of presence of hypertension, hyperlipidemia, and overweight was compared to the corresponding risk factor data obtained by physical examination and blood analysis. The examinations carried out in a primary health care setting in Sweden were on a randomized population of 122 men and 127 women aged 20 to 60 years. RESULTS: Unawareness of hyperlipidemia was 71% in women and 56% in men, as compared to 29% or lower for the other risk factors. The sensitivity of self-report was 69% or higher for the other risk factors, with the exception of hypertension in women, where it was 29%. Specificity was generally high, except for hyperlipidemia. CONCLUSION: On a population level, self-reports of hypertension, hyperlipidemia, and overweight provide a feasible selection instrument by which a subpopulation with high risk factor frequency can be identified. However, the rate of misclassification is considerable. For hyperlipidemia, the benefit of self-reporting is presently limited, due to the high unawareness of this risk factor. Individual awareness and accurate knowledge about the presence or absence of risk factors needs to improve before self-reporting can be used as a reliable instrument in risk factor screening.

Four years experience of a cardiovascular opportunistic screening and prevention programme in the primary health care in Sollentuna, Sweden.

OBJECTIVE: To study the feasibility of a cardiovascular prevention programme. DESIGN: Opportunistic screening for cardiovascular risk factors. Advice and treatment to reduce identified cardiovascular risk factors. Individually designed follow-up. SETTING: Primary health care in Sollentuna (51,000 inhabitants), Sweden. SUBJECTS: Visitors to health care centres. MAIN OUTCOME MEASURES: Feasibility and effectiveness to reduce identified cardiovascular risk factors. RESULTS: During 4 years 5622 persons, of whom 4655 (83%) were in the age group 20-60 years, participated in the programme. The prevalences of risk factors as smoking, overweight, hypertension, hypercholesterolaemia and hypertriglyceridaemia were high. At follow-up investigations, mean S-cholesterol levels were reduced by 7% among men and 10% among women. S-triglycerides were reduced by 24% and 42%, respectively. Diastolic blood pressures were reduced in men from 95 to 90 mmHg and in women from 94 to 88 mmHg. However, no effects on weight were noted and due to a low follow-up rate meaningful analysis of smoking habits was not possible. CONCLUSION: A programme for cardiovascular screening and prevention can be integrated in the primary health care system. Prevalent cardiovascular risk factors like hypercholesterolaemia, hypertriglyceridaemia and high blood pressure were significantly reduced after intervention.
