Special units in this field are public hospitals which are required to prepare a lot of reports to various institutions, including the ownership body. The paper focuses on two issues. The first is the presence of behavioral factors in the reporting of public hospitals in Poland to the ownership bodies. This article aims to indicate the thematic areas of specific reports, most affected by behavioral factors and explain the causes and consequences of their occurrence. The second issue is the analysis of the legal status of obligatory reporting of public hospitals. Participants of the conducted research, due to their specific ownership and political and social position, were public hospitals in Poland. The paper uses the research methods of the meta-analysis of the literature, legal acts in Poland and empirical materials, and also the methods of synthesis, observation, and deduction. Data analysis focused on specific sample of reports issued by Polish public hospitals for their ownership body. The research shows that hospitals draw up a tremendous number of often thematically overlapping and redundant reports addressed to different institutions in different time periods. It is a consequence of legal regulations failing to streamline the reporting of the health care sector institutions, in particular public hospitals. The paper points to the large number of legal instruments that contain imprecise requirements resulting from the complex and obscure forms of control of public funds allocation in this sector. There are many behavioral factors that shape some fields of public hospitals＇ reports, for example, interpersonal relationships, egoism, private financial interests, strengthening of the employment status and professional position, and professional competences. There is considerable freedom in the reporting process fulfilled by public hospitals in Poland for their ownership body. It causes strong consequences, like poor-quality data, duplication of information, and its chaos, as well as high costs of obtaining information. Reporting system of financial and non-financial data of public hospitals in Poland is dysfunctional.展开更多

文摘Background:Emerging epidemiological evidence suggests that compared to engaging in 1 activity mode alone,a combination of moderate-tovigorous physical activity(MVPA:brisk walking/jogging,cycling)and muscle-strengthening exercise(MSE:push-ups/sit-ups,using weight machines)has more favorable associations with optimal weight status.However,few studies have examined the dose-dependent and joint associations of MVPA and MSE with obesity.Methods:Based on cross-sectional analyses of the European Health Interview Survey Wave 2(2013-2014),we examined prevalence ratios(PRs)of joint and stratified associations between MVPA(4 categories:(ⅰ)0 min/week,(ⅱ)1-149 min/week,(ⅲ)150-299 min/week,and(ⅳ)≥300 min/week)and MSE(3 categories:(ⅰ)0 day/week,(ⅱ)1 day/week,and(ⅲ)>2 days/week)with body mass index-defined obesity(body mass index of>30.0 kg/m2)using Poisson regression with robust error variance.PRs were examined unadjusted and adjusted for sociodemographic and lifestyle characteristics(e.g.,sex,age,education,income,and smoking status).Results:Data were available for 280,456 adults(≥18 years),of which 46,166(15.5%)were obese.The interaction MVPA x MSE guideline adherence was statistically significant for obesity(p≤0.05).The joint MVPA-MSE analysis showed that compared to the reference group(i.e.,no MVPA and no MSE),the PRs followed a dose-dependent pattern,with the lowest observed among those reporting≥150 MVPA min/week and≥1 MSE days/week(PR:0.43;95%confidence interval:0.41-0.46).When stratified across each MVPA strata,the PRs were mostly lower among those engaging in MSE 1 day/week,as compared to those doing MSE≥2 days/week.Conclusion:"There was evidence for a dose-dependent association between joint MVPA-MSE with a reduced prevalence of obesity.Public health strategies for the prevention and management of obesity should recommend both MVPA and MSE.
