Determinants of Outpatient Physician Visits and Hospitalizations in Bulgaria: A Cross-Sectional Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aims: The aim of this study was to identify the determinants of outpatient physician visits and hospitalizations in Bulgaria. Given resource disparities and hospital overutilization, understanding healthcare misuse or underuse could improve system efficiency and cost management. Methods: An online survey was conducted in Bulgaria (January-February 2023) among individuals aged 18+ to collect information on individual characteristics and the use of health services. The cross-sectional study analyzed primary data from 1292 respondents. Determinants were selected based on the Andersen's behavioral model. The number of outpatient physician visits (GP, specialist) as well as the number of hospitalizations in the past 12 months were used as outcome measures. Four negative binomial regressions were conducted to assess associations between the independent and the dependent variables. Results: GP visits were positively associated with family size and trust in provider. Older age, higher education, and part-time or unemployed status were associated with lower private visits to specialists. Higher income predicted fewer GP and referral-based specialist visits. In contrast, long waiting times, distance, and transportation challenges increased private consultations. Better self-rated health was a negative predictor of GP and specialist visits. The presence of one or more chronic conditions was associated with more outpatient physician visits and more hospitalizations. Conclusion: We have applied the Andersen's behavioral model, facilitating comparative analyses based on results in different countries and health systems. Future studies should explore how these utilization patterns influence health outcomes in Bulgaria.
