Abstract:

Objective: To analyze the fairness and service capacity of human resources allocation among hospital departments based on diagnosis related groups (DRG). Methods: The DRG-related data such as service amount and DRG weight of the main departments (tuberculosis department, oncology department, thoracic surgery department) of Beijing Chest Hospital Affiliated to Capital Medical University from 2017 to 2019 were collected from “Hospital Inpatient Medical Records” and “Beijing Regional Inpatient Medical Service Performance Evaluation Platform”. A retrospective study method was used to evaluate the fairness and service capacity of inter-departmental physician human resource allocation by using indicators such as health resources agglomeration degree (≥1 indicates that the fairness of health human resources is relatively high and human resources are relatively sufficient), concentration index (“positive value” indicates physician manpower DRG indicators such as resources are distributed in departments with high service amount), carrying capacity coefficient (>1 means that medical institutions are overloaded and have strong service capabilities). Results: From 2017 to 2019, the inpatient service amount of tuberculosis department, oncology department and thoracic surgery department were 12505, 16831 and 12137, respectively, and the total weights were 14690.60, 13904.75 and 14638.01, respectively. The number of physician person-month were 1039.5, 1219.8, and 892.0, respectively. According to the service amount, the concentration of human resources of tuberculosis physicians was >1; from the perspective of DRG weight, the concentration of human resources of oncologists was >1. The concentration index of the three types of departments was less than 0 from the analysis of two dimensions. The number of hospitalizations per capita in the tuberculosis department was 144.36 cases, which was slightly lower than that in the oncology department (165.58 cases), thoracic surgery department (163.28 cases). The per capita DRG weight of oncology department was the lowest (136.79), followed by tuberculosis department (169.59), and thoracic surgery department was the highest (196.92). Conclusion: The results of human resource allocation analysis based on the two dimensions of inpatient service amount and DRG weight were significantly different, and the DRG weight of patients admitted by the department was significantly affected. According to the DRG payment principle, the efficiency of human resource allocation in departments with less patient weight could be improved by improving patient turnover efficiency and controlling unreasonable expenses.
