摘要

Objective: The aim of this study is to evaluate whether (1) the data follow a normal distribution in physical therapy human resource at hospitals (2) same data distribution between physical therapists and occupational therapists displays in hospitals (3) skewness distribution can assist Gini coefficient of health human resources (HHR) to detect statistically significant difference, and to facilitate policy decision making in regard to physical therapy human resource. Methods: This study uses the database from the HHR registry statistics maintained by the Department of Health in Taiwan. The registered population of physical and occupational therapists is recruited from nineteen medical centers and sixty regional hospitals, each of which contains over 100 beds. The data is analyzed by author-programmed Excel-VBA module. We calculated the 95% confidence interval of skewed distribution using Bootstrapping method with randomly sampling with replacement from the original dataset. Besides, we also fabricate a set of figures that is comparable to human resource of physical therapy professionals between hospital levels. for which Gini coefficient in different administrative units (county, town, city, and district) between year 1997 and 2006 is compared to find statistically significant difference by skewness analysis. Results: According to the visual representation of skewness coefficients. we found that (1) there is inequality with positively skewed distribution of physical therapy in hospitals (2) there is equivalent distribution between physical therapists and occupational therapists in the same level of hospitals (3) skewness coefficient cannot provide Gini coefficient in inference making Conclusions: During 1997-2006, Gini coefficient of physical therapy HHR in more urbanized area demonstrates positive increment. The HHR ratio of physical therapy by every 100,000 population shows negatively skewed distribution, which means the manpower of physical therapy has obviously increased in that period (p＜0.05). Overall, the results can be a policy reference in decision making regarding evaluation and comparison of physical therapy human resource.
