| Abstract:: |
| Objective To ascertain the basic situation of radiotherapy in Fujian in 2016. Methods Based on the unified questionnaire, the types and quantity of radiotherapy and its corollary equipment, the number of radiotherapy staff and the work for quality control were surveyed in the radiotherapy units in the whole province, and the data on patients undergoing radiotherapy and other types of patients were collected from 26 hospitals. The total number of radiotherapy patients in the whole province was estimated by the correlation analysis and multiple linear regression analysis. Results Radiotherapy was performed in a total of 32 hospitals in Fujian province in 2016. Among them, there were 62 sets of radiotherapy equipment, 33 sets of the simulators, 57 sets of treatment planning systems and 762 staff. The total number of 15156 radiotherapy patients in 26 hospital were available for the survey. Multiple linear regression models showed that the frequency of application of medical electron accelerator were positively correlated with number of outpatients, emergency patients and inpatients, number of radiotherapy staff, number of electron accelerators (r=0.311, 0.893, 0.956, P<0.05). It also showed that the frequency of aterloading brachytherapy were positively correlated with number of outpatients, emergency patients and inpatients, number of radiotherapy staff, number of aterloading brachytherapy units (r=0.307, 0.966, 0.988, P<0.05). The frequency of radiotherapy was 0.54 patients per 1000 population in Fujian in 2016. The delivered dose calibration of accelerators was performed in all hosptitals involved in line with the relevant regulations, but the number of quality control equipment for radiotherapy was insufficient, such as the QA beam checker or well-type ionization chamber. Conclusions In recent years, the rapid development of radiotherapy has been seen in Fujian province. The radiotherapy management should be focused on standardernized and improved quality control and regulation in future. |
