Association between anthropometric obesity measures and coronary artery disease: a cross-sectional survey of 16,657 subjects from 444 Polish cities.

BACKGROUND: Excessive body weight is known to cluster with cardiovascular (CV) risk factors, but it is not clear which anthropometric obesity measure provides best independent predictive value of coronary artery disease (CAD). METHODS AND RESULTS: We explored associations between CAD and four different obesity measures (body mass index (BMI), waist circumference, waist/height and waist/height(2)) in a cohort of 16 657 subjects (40.4% men; 20.8% CAD patients), recruited by 700 primary care physicians in 444 Polish cities. 42.8% of subjects were classified as overweight, 31.7% as obese and 39.8% had abdominal obesity. In univariate analyses all obesity measures correlated with CAD (p>0.001), but waist/height(2) was the strongest discriminator between CAD patients and controls. Age-adjusted and sex-adjusted analyses confirmed a graded increase in CAD risk across distributions of all four obesity measures-1 standard deviation (SD) increase in BMI, waist, waist/height and waist/height(2) increased the odds of CAD by 1.23, 1.24, 1.26 and 1.27, respectively (all p<0.001). In models fully adjusted for CV risk factors, waist/height(2) remained the strongest obesity correlate of CAD, being the only independent associate of CAD in men. In a fully adjusted BMI-waist circumference stratified model, sarcopenic obesity (waist > median, BMI < median) and simple obesity (waist and BMI > median) were the strongest independent associates of CAD in men (p = 0.008) and women (p>0.001), respectively. CONCLUSION: This cross-sectional study showed that waist/height(2) may potentially offer a slightly higher predictive value of CAD than BMI or waist circumference and revealed an apparent sexual dimorphism in correlations between obesity measures and CAD.

Transient ischaemic attacks: desired diagnosis and management by Polish primary care physicians.

OBJECTIVE: The aim of this study was to assess the competence of Polish primary care physicians in diagnosing and managing patients with transient ischaemic attacks (TIAs) in the carotid territory. METHOD: A written questionnaire was distributed to all first-contact physicians (n = 100) in one of the seven health care districts of Warsaw (response rate 89%). The questionnaire included three pairs of TIA cases. In each of the pairs, only the age and type varied. Three cases were characterized by transient monocular blindness and the other three by symptoms of hemispheral ischaemia. RESULTS: Physicians confronted with TIA cases had difficulties in diagnosing it. In the cases of monocular blindness, only 20-44% of cases were diagnosed correctly, and hemispheral ischaemia was diagnosed correctly in 46-78% of cases. Patients with no history of non-specific symptoms and with the first attack would have a higher percentage of correct diagnoses in comparison with those with recurrent attacks and a history of non-specific symptoms. Patients with hemispheral ischaemia frequently would be referred to neurologists, and about two-thirds of doctors would refer patients with monocular blindness to ophthalmologists, and fewer than half to neurologists. Antiplatelet therapy would be prescribed by <22% of physicians, while peripheral vasodilatators would be prescribed by up to 60% of them. CONCLUSION: The results of this study indicate that Polish primary care physicians when confronted with TIA cases would have basic difficulties, especially in diagnosis and management. These results underline the need for changes in the vocational training of primary care physicians, with special attention to frequent family medicine problems.

Enrolment procedures and self-selection by patients: evidence from a Polish family practice.

This paper examines the consequences of patient enrollment procedures in a capitation-based family practice in Krakow (Poland), where the local city government used two different methods for preparation of patient lists. In the first, the city gave the individuals living within the practice area the option of withdrawing from being enrolled in the practice; in the second, individuals were given the option of enrolling in the practice. These two enrollment procedures, identified as 'active-negative' and 'active-positive' respectively, provide a natural experiment for investigating the effects of an enrollment methodology on the economics of a physician's practice. An examination of the data indicates that self-selecting enrollees utilize significantly greater quantities of health care compared to others, and university educated individuals and individuals more likely to fall ill are more likely to self-select into a practice. The study suggests that in order to reduce demand-side adverse selection, either the system of active-positive enrollment should be modified, or capitation rates should be risk-adjusted by health status rather than by demographic variables only. The policy implications of this study become even more significant as more and more physicians leave their salaried jobs to start state-financed independent practices.

The Polish experience of quality improvement in primary care.

THE POLISH HEALTH CARE SYSTEM: The health care system in Poland is based on a model typical of east-central European countries, with features such as state-owned health care organizations, centralized management and administration, and primacy of access to care over quality. Poorly planned and uncoordinated reforms have been undertaken to transfer some of the authority for health service management to local governments. PRIMARY HEALTH CARE IN POLAND: The reform of the health care system entails substitution of family physician-based for medical specialist-based primary care. Newly trained family physicians, as the first to start private surgery clinics financed from public sources, are the forerunners of the comprehensive reform and property structure transformation. MAKING THE TRANSITION FROM QUALITY ASSURANCE TO QUALITY IMPROVEMENT: Since the early 1990s, more and more organizations, individuals, and professional groups have begun to perceive health care regulations and other external control mechanisms as ineffective. Attempts have been made to replace periodic, restrictive activities with systematic continuous quality improvement efforts. Systems of voluntary accreditation are being developed and fostered. Groups have started meeting to develop medical practice guidelines and conduct peer review. Concern about quality of health care services is now reflected in the Polish legislation for the first time, as well as in numerous local and nationwide projects and publications. CONCLUSION: Despite some successes, the pioneers of quality improvement (QI) still have a long way to go. Continuation of educational activities and creation of a system of motivation for the development, of QI in primary care should be prioritized and encouraged.

Are antibiotics over-prescribed in Poland? Management of upper respiratory tract infections in primary health care region of Warszawa, Wola.

BACKGROUND: Concern about the increasing numbers of multiple resistant strains resulting from over- and misuse of antibiotics is growing world-wide. METHOD: A questionnaire based on two cases related to respiratory tract infections for which antibiotic prescription was disputable was sent to primary care physicians in the health care district of Warszawa, Wola, Poland. RESULTS: The prescription percentage for both cases was high, with a large variety in choice of antibiotic therapy made by the doctors. This finding was striking when compared with the more restrictive prescription behaviour of Dutch general practitioners. Moreover, this high prescription percentage was combined with other abundant activities. In the case of the patient with acute tonsillitis, 53% of the primary care physicians would have ordered additional tests, 94% would have advised bed-rest and 9% would have referred. In the sinusitis case, these figures were 88, 74 and 54% respectively. No correlations were found between choice of antibiotics and characteristics of the physicians such as age, gender, experience with working in primary health care or degree of specialization. CONCLUSIONS: In conclusion, the results of this small pilot study indicate that Polish first-contact doctors have an inadequate prescription behaviour in cases with upper respiratory tract infections. Our results underline the need for courses in pharmacotherapy within the postgraduate education course in family medicine recently introduced in Poland.
