Health technology assessment in Sweden.

Sweden has a welfare system that is based on the fundamental principle that all citizens are entitled to good health and medical care, regardless of where they live or what their economic circumstances are. Health and medical care are considered to be public sector responsibilities. However, there is growing interest in establishing more private alternatives to public care. An important characteristic of the Swedish healthcare system is its decentralization, with a major role for county councils. County councils are now merging into larger administrative units (region). The whole Swedish system is in the process of reform, mainly because of perceptions that it was too rigid and had insufficient patient orientation. An important factor in the reforms is that power in the system will be even more decentralized and will have greater public input. This change is seen as calling for increased central follow-up and evaluation of matters such as social, ethical, and economic aspects. Although the state has decentralized control, it still attempts to control the general direction of the system through regulation, subsidy, recommendations, and guidelines. An important actor in the system is the Swedish Council on Technology Assessment in Health Care (SBU). SBU began in 1987 with assessments of health technologies, but its success has recently led policy makers to extend its coverage to dental care. Health technology assessment is increasingly visible to policy makers, who find it useful in decision making.

Comparison of diabetic and non-diabetic patients referred for coronary angiography.

AIM: To evaluate whether diabetic patients differ from non-diabetic patients when referred for coronary angiography regarding previous history, indication for and findings at coronary angiography, use of medication, exercise test results and mortality. METHODS: Data were prospectively collected on patients referred for consideration of coronary revascularization to seven of the eight public Swedish heart centers that performed approximately 92% of all bypass operations in Sweden in 1994. RESULTS: 2762 patients were included of whom 406 (15%) had a history of diabetes mellitus. There was no difference in age or sex in the two groups. Chronic stable angina was the most common indication (73% in both groups) and only 3% were admitted due to silent ischemia. Diabetic patients had more severe symptoms (Canadian Cardiovascular Society III-IV) than non-diabetic patients (66% vs. 58%, p<0.01). They more frequently used ACE-inhibitors (33% vs. 19%, p<0.0001) and calcium channel blockers (47% vs. 40%, p<0.01) and more often had a diagnosis of arterial hypertension than non-diabetic patients (50% vs. 33%, p<0.0001). Diabetic patients more often had depressed myocardial function (EF<35%); 12% and 8%, respectively (p<0.01), and more extensive coronary artery disease (left main/3-VD; 48% vs. 37%, p<0.001). The mortality during the subsequent 21 months was 7.9% among diabetic patients and 3.6% among non-diabetic patients (p<0.001). CONCLUSION: Among patients being referred for coronary angiography in Sweden, 15% were patients with a history of diabetes. They differed from patients without such a history by more often having severe symptoms and a higher prevalence of left main/triple vessel disease. Coronary angiography may thus be underused in diabetic patients with chest pain.

Factors associated with the use of various medications amongst patients with severe coronary artery disease. SECOR/SBU Project Group.

AIM: To describe variations by age, sex, symptom severity and hospital region in the use of various medications amongst patients with stable angina pectoris who are candidates for coronary revascularization. PATIENTS: Patients (n = 2030) with chronic stable angina pectoris participating in a national survey evaluating the appropriateness of the use of percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG). METHODS: As part of a national study of the appropriateness of coronary revascularization, data were prospectively collected on patients referred for consideration of coronary revascularization to seven of the eight public Swedish heart centres that performed approximately 92% of all bypass operations in Sweden in 1994. RESULTS: Amongst all patients 76% were treated with beta blockers, 41% with calcium antagonists and 71% with long-acting nitrates and 70% were treated with at least two of these three drugs. Eighty-two per cent of the patients used aspirin and 14% lipid-lowering drugs. According to logistic regression analysis, with medication as the dependent variable and independent variables of age, sex, angina functional class, findings at exercise test, history of various diseases and region in Sweden where the investigation took place, the most consistent factor explaining the use of various medications was found to be geographical region. A previous history of acute myocardial infarction (AMI) was also associated with the use of all drugs and age was associated with all with the exception of beta blockers. Sex was not an independent factor explaining the use of any of the drugs. CONCLUSION: In a national survey including patients with stable angina pectoris who are potential candidates for coronary revascularization, the most important predictor for the use of various medications was the geographical region in which the investigation took place.
