The importance of comorbidity in analysing patient costs in Swedish primary care

BackgroundThe objective was to explore the usefulness of the morbidity risk adjustment system Adjusted Clinical Groups® (ACG), in comparison with age and gender, in explaining and estimating patient costs on an individual level in Swedish primary health care. Data were retrieved from two primary health care centres in southeastern Sweden.MethodsA cross-sectional observational study. Data from electronic patient registers from the two centres were retrieved for 2001 and 2002, and patients were grouped into ACGs, expressing the individual combination of diagnoses and thus the comorbidity. Costs per patient were calculated for both years in both centres. Cost data from one centre were used to create ACG weights. These weights were then applied to patients at the other centre. Correlations between individual patient costs, age, gender and ACG weights were studied. Multiple linear regression analyses were performed in order to explain and estimate patient costs.ResultsThe variation in individual patient costs was substantial within age groups as well as within ACG weight groups. About 37.7% of the individual patient costs could be explained by ACG weights, and age and gender added about 0.8%. The individual patient costs in 2001 estimated 22.0% of patient costs in 2002, whereas ACG weights estimated 14.3%.ConclusionACGs was an important factor in explaining and estimating individual patient costs in primary health care. Costs were explained to only a minor extent by age and gender. However, the usefulness of the ACG system appears to be sensitive to the accuracy of classification and coding of diagnoses by physicians.

Smoking cessation in patients with diabetes mellitus: Results from a controlled study of an intervention programme in primary healthcare in Sweden

Objective. To evaluate an intervention programme on smoking cessation in patients with diabetes mellitus in primary healthcare. Design. Regional controlled intervention study. Setting. Seventeen primary healthcare centres in Sweden. Intervention. In the intervention centres, nurses with education in diabetes were given one half-day of training in motivational interviewing and smoking cessation. An invitation to participate in a smoking cessation group was mailed to patients from the intervention centres followed by a telephone call from the patient's diabetes nurse. The nurses who intervened were specially educated in smoking cessation. The control group received a letter containing advice to stop smoking and information about a one-year follow-up. Patients. Daily smokers with diabetes mellitus, 30–75 years of age. In the intervention centres 241 patients fulfilled the criteria and in the control centres 171 patients. Main outcome measures. Self-reported smoking habits after one year. Results. In total, 21% of the smokers accepted group treatment. After 12 months, 20% (42/211) in the intervention centres reported that they had stopped smoking and 7% (10/140) in the control centres; 40% (19/47) of the smokers who had participated in group treatment reported that they had stopped smoking. Conclusion. A computerized record system for patients in primary healthcare was used to identify diabetic patients who were smokers. The selected group was invited to a stop smoking programme. At a one-year follow-up significantly more patients in the intervention centres had stopped smoking compared with patients in the control centres.

Cost of heart failure in Swedish primary healthcare

Objectives. To calculate the cost for patients with heart failure (HF) in a primary healthcare setting. Design. Retrospective study of all available patient data during a period of one year. Setting. Two healthcare centers in Linköping in the southeastern region of Sweden, covering a population of 19 400 inhabitants. Subjects. A total of 115 patients with a diagnosis of HF. Main outcome measures. The healthcare costs for patients with HF and the healthcare utilization concerning hospital days and visits to doctors and nurses in hospital care and primary healthcare. Results. The mean annual cost for a patient with HF was SEK 37 100. There were no significant differences in cost between gender, age, New York Heart Association functional class, and cardiac function. The distribution of cost was 47% for hospital care, 22% for primary healthcare, 18% for medication, 5% for nursing home, and 6% for examinations. Conclusion. Hospital care accounts for the largest cost but the cost in primary healthcare is larger than previously shown. The total annual cost for patients with HF in Sweden is in the range of SEK 5.0–6.7 billion according to this calculation, which is higher than previously known.

Determinants of medicine use in a Swedish primary health care practice population

Pharmaceuticals represent an increasing share of private and public health care expenditures. The aim of this study was to characterise users and to determine the pattern of uses of prescribed medicines and to identify determinants of medicine use in a multi-ethnic Swedish general practice population. The study was performed in 1055 of 1442 consecutive adult patients visiting the Jordbro Health Centre (JHC) in Stockholm, Sweden. In a regression analysis adjusted for the influence of confounders, subjects reporting 10-30 complaint symptoms, subjects with chronic disease and subjects that had a cost limitation card all reported a higher number of used medicines than subjects with a few (0-10) symptoms and those without chronic disease and a cost limitation card. In a Poisson's regression analysis, high age, female gender, not working, more than 10 symptoms, chronic disease and having a cost limitation card were related to use of prescribed medicines. All included variables predicted 19% of the explanation. Marital status, multi-symptomatology, chronic disease and having a cost limitation card were related to polypharmacy in a logistic regression analysis. A high number of complaint symptoms, chronic disease and having a cost limitation card were all significantly and independently related to use of medicines and polypharmacy.

Anticoagulant treatment of patients with chronic atrial fibrillation in primary health care in Sweden--a retrospective study of incidence and quality in a registered population.

The number of patients receiving anticoagulant treatment is increasing. Chronic atrial fibrillation is the most common treatment diagnosis. The literature indicates a variable level of treatment control. Estimates of time within the therapeutic range have been recommended as a measurement of quality. Electronic patient records are providing clinical data that are useful for audits concerning anticoagulant treatment in real-life practice. Our aim was to assess warfarin treatment for chronic atrial fibrillation in primary health care with regard to prevalence, incidence and quality. A 2 year retrospective study was carried out of electronic patient records up to April 2002 in primary health care in Stockholm, including 12 primary health care centres with a registered population of 203 407. Main outcome measures were the number of new patients on wafarin treatment for chronic atrial fibrillation, and time within the therapeutic prothrombin range in the first 90 days of treatment using a linear interpolation method. In total, 827 patients were on warfarin treatment for chronic atrial fibrillation, giving a prevalence of 0.41%. Of these, 144 patients (study group) started treatment with warfarin for chronic atrial fibrillation during the study period, giving a yearly incidence of 0.07%. Their mean age was 73.1 years and 61.1% were men. There were 1721 prothrombin monitoring episodes registered in the first 90 days of treatment, on average once a week per patient. The average proportion of time within the therapeutic range was 54.1% (95% confidence interval (CI) 50.1-58.1), and the proportion of therapeutic tests was 50.2% (95% CI 47.8-52.6). During the first, second and third months of warfarin treatment for chronic atrial fibrillation, patients were outside the therapeutic range time nearly half the time. There was a gender difference favouring men regarding initiation of treatment.

Determinants of complementary alternative medicine (CAM) use

The aim of this study was to describe the pattern of use of complementary alternative medicine (CAM) and identify the determinants of CAM use in a multi-ethnic Swedish primary health care practice population. A questionnaire was handed out to 1433 patients aged 16 years and above who visited the Jordbro Health Centre (JHC) in Stockholm, Sweden, between 14 January and 30 June 2002. The results were linked to computerised medical records. Seventeen percent of respondents had consulted a CAM provider during the preceding year and many patients had consulted several types of CAM providers. The most frequently CAM used was massage, followed by acupuncture, chiropractic and naprapathy. In the logistic regression, when adjusting for the influence of possible confounders, chronic disease and physical activity were the most important predictors of consultations with CAM providers. Users of CAM had had a higher number of consultations with medical professionals than had non-users of alternative medicine. In our study population CAM, defined here as "manual therapy", was used in addition to traditional therapies and was related to high use of health care services. Chronic disease and physical activity were significantly and independently related to use of CAM.

Gender differences in risk factor control and treatment profile in diabetes: a study in 229 Swedish primary health care centres

Objective To measure the risk factors and treatment profile of diabetes patients treated in primary health care (PHC) in order to evaluate potential gender differences.Design Cross-sectional survey of consecutive diabetes patients.Setting 229 PHC centres in Sweden.Subjects 5082 men and 4293 women with diabetes were investigated (1998–2001).Main outcome measures Glycaemic control (HbA1c), blood pressure, lipid levels, prevalence of left ventricular hypertrophy and microalbuminuria. Proportions of patients with previous ischaemic heart disease (IHD) and specific drug treatment.Results Male patients generally had better blood pressure (<140 and/or 85 mmHg) and glycaemic (HbA1c <6.5%) control than corresponding female patients (44% and 59%, versus 40% and 54% in the 60–75 year age group; p<0.01). Females showed higher levels of total (p<0.01) and HDL cholesterol (p<0.05) than males in all age groups. No gender difference was detected for LDL cholesterol levels in the younger or elderly patients, but in the age group 60–75 years female patients had significantly higher mean LDL cholesterol level than male patients (3.3 vs 3.2 mmol/L; p<0.05). Previously known manifestations of IHD were more common (p<0.01) in male patients.Conclusion Elderly male patients with diabetes had a more favourable risk factor control than corresponding female patients.

Occurrence and quality of anticoagulant treatment of chronic atrial fibrillation in primary health care in Sweden: a retrospective study on electronic patient records.

BackgroundChronic atrial fibrillation is a prevalent cardiac disorder. The literature indicates varying proportions of those treated with anticoagulants, and varying intensity of anticoagulation. Electronic patient records are providing us with clinical data concerning management of anticoagulant treatment in real-life practice that is useful for audits. We aimed to assess warfarin treatment for chronic atrial fibrillation in primary health care with regard to prevalence, incidence, the proportion treated and the quality of anticoagulation control.MethodsFive primary health care centres in Stockholm with a registered population of 75146 participated in a one-year retrospective study of electronic patient records up until May 2000. All patients over 18 years of age with an encounter labelled 'Atrial fibrillation' were identified, and all records of patients on warfarin treatment were manually reviewed. Main outcome measures were number of patients with chronic atrial fibrillation, number of patients on wafarin treatment, and time within the therapeutic prothrombin range.ResultsIn total, 419 patients had chronic atrial fibrillation, giving a prevalence of 0.60% (age-adjusted 0.62%), the age group 65 years or older accounted for 91.6%, and 50.1% were women. Out of these, 50.4% (211 patients) were established on warfarin treatment for chronic atrial fibrillation (0.28% of the population), and there was a predominance of men (p = 0.02). Fifty-four patients started treatment with warfarin for chronic atrial fibrillation (0.07% of the population). Among 25 randomly selected patients on established treatment, the proportion of time within the therapeutic range was 70.2%. Among 24 randomly selected patients starting treatment, the proportion of time with therapeutic values was 54.2% and 66.9% the first and second months of treatment, respectively.ConclusionsChronic atrial fibrillation is common among the elderly in primary health care, and about half of these patients are treated with warfarin. It appears to be under-diagnosed, and may also be under-treated. About two thirds of treatment time is spent within the therapeutic range, and further improvement of the quality of anticoagulation control with warfarin may therefore be hard to achieve.

Determinants of drug utilisation in a Swedish municipality.

The cost for pharmaceuticals is rapidly increasing in most countries. Identification of the characteristics of the population that determine drug utilisation appears essential for the appropriate allocation of resources to caregivers. The primary aim of this study was to identify sociodemographic factors and measures of well-being and disease that were independently related to the use of drugs, including herbal, and self-care products in Håbo, a Swedish primary health care district. Another aim was to evaluate combinations of such factors that may improve the prediction of drug utilisation. A postal questionnaire was sent to a representative age-stratified population sample from Håbo. Out of 1312 subjects in the population sample, 827 (63%) answered the questionnaire. The questionnaire contained questions on sociodemographic variables, well-being and symptoms and use of drugs, herbal and self-care products. Chronic disease was the most important of several factors that identified users of drugs. Other important factors were female sex, poor perceived health, sick-leave or disability pension and a high number of symptoms (complaint score). When combined, these variables could explain 18% of the use of prescribed pharmaceuticals using the logistic regression model. Several sociodemographic characteristics as well as perceived health, complaint score and chronic disease were independently related to the use of drugs and self-care products. The likelihood of using prescribed drugs was very high in subjects with a certain profile. Eighteen per cent of the use could be attributed to this profile.

Anticoagulant treatment in primary health care in Sweden - prevalence, incidence and treatment diagnosis: a retrospective study on electronic patient records in a registered population.

BackgroundThe indications for warfarin treatment in primary health care are increasing. An undertreatment with warfarin is reported in the prevention of embolic stroke in patients with chronic atrial fibrillation, and can be suspected for other indications. Information on the prevalence and incidence of diseases treated with warfarin would reveal useful data for audits concerning management of anticoagulant treatment. We aimed to assess warfarin treatment in primary health care with regard to prevalence, incidence, treatment diagnosis and patient characteristics.MethodsA one-year retrospective study of electronic patient records up to May 2000 in primary health care in Stockholm, Sweden. Five primary health care centres with a registered population of 75 146. Main outcome measures were prevalence, incidence and treatment diagnosis.ResultsFive hundred and seven patients, mean age 71.9 years, were on warfarin treatment. The prevalence was 0.67% (age-adjusted 0.75%), and it was significantly higher for men (0.78%) than for women (0.58%) (p = 0.01). In the age group 75–84 years the prevalence was 4.54%. The most prevalent treatment diagnosis was chronic atrial fibrillation (0.28%), which was more predominant for males (p = 0.02), followed by cerebrovascular disease (0.13%) and deep venous thrombosis (0.13%). The yearly incidence of warfarin treatment was 0.17%, with chronic atrial fibrillation as the predominant treatment diagnosis.ConclusionWarfarin treatment in primary health care is prevalent among the elderly. Chronic atrial fibrillation is the main treatment diagnosis. There is a gender difference favouring men in general and chronic atrial fibrillation as the treatment diagnosis.

Heart Failure in the Elderly: Characteristics of a Swedish Primary Health Care Population

Background: Heart failure (HF) is a challenge to diagnose and treat according to guidelines. Few studies have been performed in elderly subjects with symptoms that might be associated with HF in primary health care. Objective: To study elderly patients presenting with symptoms possibly associated with HF, with respect to systolic and diastolic function, B-type natriuretic peptide (BNP) levels and treatment. Methods: A cardiologist examined 415 elderly (65–82 years) patients with symptoms of dyspnoea, fatigue and/or peripheral oedema. All patients underwent echocardiography and plasma BNP determination. Systolic function was determined semiquantitatively, and ejection fraction (EF) <40% was considered to be reduced. Abnormal diastolic function was defined as a reduced ratio of peak early diastolic filling velocity to peak filling velocity at atrial contraction (E/A ratio; age adjusted) or an abnormal pattern of pulmonary venous flow. Results: Forty-eight percent of the patients showed abnormal systolic (26%) or diastolic function (22%). A majority of the patients with diastolic HF had relaxation abnormalities and neither pseudonormal nor restrictive filling patterns. Increased levels of BNP were found in the group with impaired systolic function. More than half of those with EF <40% were not receiving angiotensin-converting enzyme inhibitions at all, or were on a suboptimal dose, whereas others were on treatment for an HF diagnosis despite normal cardiac function. Conclusion: Diagnostic tools that are more objective than clinical examination are needed for the diagnosis of HF.

Patient based 'burden-of-illness' in Swedish primary health care. Applying the Johns Hopkins ACG case-mix system in a retrospective study of electronic patient records.

Patients from one municipality in Sweden utilizing primary health care (PHC) during 1998 and 1999 have been categorized into 81 groups. The groups show each patient's own case-mix in terms of illness. Grouping was carried out using the case-mix instrument adjusted clinical groups (ACG), developed by the School of Hygiene and Public Health at Johns Hopkins University in Baltimore, USA. The resulting pattern provided a more adequate reflection of the scope of primary care's task than that yielded by diagnoses alone. Changes over time in terms of illness patterns for a population could be described, analysed and assessed from medical and health economic perspectives. One of the conclusions from this study was that the ACG instrument is a relevant tool in describing the outcome of work by the primary health care centre. The ACG is of interest in the improvement of the quality of primary care in Sweden. The ACG should be a driving force in the development of health indices in both national and international comparisons, as a result of its focus on the health status of patients and populations instead of on diagnoses and diseases.

'Carer and gatekeeper' - conflicting demands in nurses' experiences of telephone advisory services.

'Carer and gatekeeper' - conflicting demands in nurses' experiences of telephone advisory services Millions of calls are made to the telephone advisory services in primary health care in Sweden. The patients seem happy with the advice and counselling they receive, but little has been written about nurses' experiences of performing telephone advisory services. Yet, the nurses are expected to be patient, sensitive and have a broad knowledge of medicine, nursing and pedagogy. The aim of this study was to describe how nurses experience the patient encounter when performing telephone advisory services. A strategic sample of five nurses were interviewed and asked to describe how they experienced the central aspects of the patient encounter by telephone. The transcribed interviews were analysed by the Empirical Phenomenological Psychological method. The nurses' experience of the patient encounter when performing telephone advisory services can be characterized in terms of the conflicting demands of being both carer and gatekeeper. The constituents of these conflicting demands were: reading between the lines while pressed for time; educating patients for self-care while fearful of misinterpreting the situation; encountering patients' satisfaction and dissatisfaction. The conflicting demands of being both professional carer and gatekeeper caused stress among the nurses. The organization of the telephone advisory services seems to hinder high-quality care.

Computerisation, coding, data retrieval and related attitudes among Swedish general practitioners—a survey of necessary conditions for a database of diseases and health problems

Objective: To investigate necessary conditions for the establishment of a database of diseases and health problems for research and health care planning, based on electronic patient records in everyday clinical use among general practitioners (GPs). Design: Postal questionnaire study. Setting: Primary health care in Sweden. Subjects: Three hundred randomly selected GPs. Main outcome measures: Degree of computerisation of patient records. User frequency and characteristics of diagnosis classification systems and coding tools. Frequency of coding activities and retrieval of codes, and related attitudes. Opinions on a primary health care version of ICD-10. Results: A total of 184 GPs (61% of the 300 GPs) were included in the study. About 92% used an electronic record system, some type of diagnostic classification was used by 93%, and ICD based classifications by 88%. The classification in use was computerised for 74%. Mainly simple tools were used to retrieve diagnostic codes. About 76% of GPs reported classifying at least one symptom or disease per encounter. The codes were retrieved ‘once a month’ or more by 19%. Classification of diseases was considered important for follow-up by 83%, and for the care of the patient by 75% of the GPs. The primary health care version of ICD-10 with a total of 972 codes was considered too limited in size by 31%. Conclusion: Electronic patient records in everyday clinical use in Swedish general practice provide several fundamentals for a database of diagnostic data. However, there are several barriers to the establishment of such a database that is both valid and reliable.

Early intervention for problem drinkers: readiness to participate among general practitioners and nurses in Swedish primary health care.

An exploration was made of attitudes and practices of general practitioners (GPs) and nurses concerning early identification of, and intervention for, alcohol-related problems. Sixty-five GPs and 141 nurses in 19 primary health centres in a county in southern Sweden answered a 28-item questionnaire before implementation of an intervention programme. The questionnaire covered experiences with patients with alcohol-related health problems, knowledge and perceived capacity concerning early identification and intervention, attitudes towards the role of primary care staff in early identification and intervention and current intervention methods in use at the health centre. Self-reported frequency of asking about alcohol use was higher among GPs than nurses. Both groups reported more frequently asking about alcohol consumption in cases where they believed that the health status was influenced by alcohol. For both professions, knowledge and skills concerning identification were rated as better understood than that concerning intervention methods. Nurses rated their knowledge and skills less confidently than GPs. The overall attitude was fairly positive towards early identification and intervention, but nurses were more worried than GPs that patients would react negatively to questions about alcohol. Attitudes, self-rated capacity, and practice were related. The low level of early identification and intervention in primary care appears to be related more to insufficient practical skills than to attitudes. Nurses appear to be an unexploited resource, in need of training and support. Nurses may need to be convinced that an active role does not interfere with the nurse-patient relationship. Building teams of GPs and nurses in primary care might enhance the dissemination of alcohol prevention into regular practice.

Blood pressure and other cardiovascular risk factors among treated hypertensives in Swedish primary health care

Objective - To evaluate antihypertensive treatment and other cardiovascular risk factors in primary health care. Design - Cross-sectional survey of consecutive patients with treated hypertension in 1999. Setting - 17 primary care centres in Sweden. Subjects - 512 patients (mean age 67; SD 11 years). Main outcome measures - Antihypertensive treatment, cardiovascular risk factors. Results - Patients with high diastolic BP ( S 100 mmHg) and systolic BP ( > 180 mmHg) values were few. The proportions with diastolic BP < 90, BP < 160/95 and < 140/90 mmHg were 64%, 54% and 15%. Mono-therapy was given in 51%, and S 3 drugs in 13%. Hypertensives with hyperlipidaemia were 42%, and only 26% of them were given lipid-lowering drugs, mainly statins, 21%. Smok ers were 10%, 23% had diabetes, and many had overweight BMI = 25 kg/m2, 72%. Conclusion - Although two-thirds had diastolic BP < 90 mmHg, few had BP below the current treatment target < 140/90 mmHg. More than half of the hypertensives had at least one additional cardiovascular risk factor, and these hypertensives also had low proportions within several current treatment targets of hypertension and hyperlipidaemia, implying a need for intensified multiple risk factor intervention.

Time for a "vision zero" concerning premature death from ischaemic heart disease?

Objective - To study the trend in premature mortality (before 75 years of age) from ischaemic heart disease (IHD) in a Swedish primary health care district compared to communities of similar demographic situation and all Sweden. Design - Mortality from IHD in men and women was compared between the community of Habo and other Swedish communities of similar size and all Sweden for the period 1984-96. Setting - The community of Habo in Sweden with about 9600 inhabitants. Intervention - Intensified efforts by the local primary health care organisation, in co-operation with the community, in respect of primary and secondary cardiovascular prevention since the beginning of the 1980s. Results - Mortality from IHD has decreased significantly both in Habo and in Sweden during these years. The decrease has been more prominent in Habo than in Sweden as a whole and other Swedish communities of similar demographic situation. Conclusion - With increased and purposeful efforts in primary and secondary prevention, in co-operation between the community and primary health care, it is possible to substantially decrease mortality from IHD in the community.

Shifts in B12 opinions in primary health care of Sweden

The diagnosis and management of vitamin B12 deficiency varies between countries and within countries. The aim of the study was to map current attitudes and values behind clinical decision-making in Swedish primary health care, which has a unique B12 tradition: two patients out of three are treated with oral high-dose cyanocobalamin. Most patients with B12-associated problems are managed in primary health care by general practitioners (GPs). The study was designed to elucidate possible opinion shifts among GPs during the period 1996-1998. GPs (n=499), stratified and randomized, received a questionnaire with 24 statements on B12-associated clinical and laboratory problems, to be evaluated by a visuo-analogue scale. The majority of GPs in primary health care in Sweden accepted homocysteine and methylmalonic acid (MMA) as markers for functional deficiency of vitamin B12. The evaluation of classical markers of B12 deficiency was wary and balanced. There was a consensus of the need for B12 therapy to risk groups such as patients with atrophic gastritis or previous gastric surgery. The answers also appeared to reflect an improvement of professional knowledge and competence concerning B12-associated problems among Swedish GPs between 1996 and 1998. The overriding conclusion was that B12-associated opinions of Swedish GPs were stable within the period studied, with marginal improvements of knowledge and competence.

Anticoagulant treatment of patients in Swedish primary health care. Safety aspects.

Assessing the quality of anticoagulant (AC) treatment in primary health care with regard to safety. Surveys of patients on AC treatment during 1999. Community health centres (CHCs) in the northeastern region of Stockholm County. Nine hundred and fifty-seven patients, from 16 CHCs. Rate of bleeding and thromboembolic events during AC treatment and rate of values within the recommended treatment interval. The reporting of prothrombin-time (PT) results changed during the year from PT values to international normalised ratio (INR). A total of 48 bleeding events in 44 patients were noted, i.e. 6.8 per 100 patient-years. Of these, ten were major bleedings, 1.4 per 100 patient-years, including three fatal bleedings, 0.4 per 100 patient-years. Six thrombo-embolic events were noted during treatment, i.e. 0.8 per 100 patient-years. Bleeding events were more common at INR values greater than 2.80 than at values of 2.80, [relative risk (RR) 3.30, 95% confidence interval 1.90-5.71]. Of all the noted PT values, 65% were within the recommended intervals (the most common being PT 15-25%) and of all noted INR values 60% (the most common being INR 2.1-3.0). No differences in the rate of bleeding or the number of thrombo-embolic events between the periods of PT and INR results were found. The rate of complications was low and AC treatment in primary health care seems to be as safe as in hospital clinics.
