Objective To investigate the general state, psychologic status and health related quality of life (HRQOL) in patients with post-herpetic neuralgia (PHN), and explore the influencing factors on HRQOL and their major and minor relationship. Methods From August 2014 to August 2015, a questionnaire survey was conducted to patients with PHN. The data of the patients’ general situation was colleted, the psychologic status was assessed by Self-rating Depression Scale (SDS), and the HRQOL of the patients was assessed by 36-item Short Form Survey. One-way ANOVA and stepwise regression analysis were used to analyze the influencing factors of HRQOL. Results A total of 177 questionnaires were issued, and 158 were recovered with a response rate of 89.3%. The average score of HRQOL of the 158 patients was 513.67±119.79, and the average score of SDS was 43.65±11.34. SDS scores showed no depression in 41 patients (25.9%), mild depression in 47 (29.7%), moderate depression in 39 (24.8%), and severe depression in 31 (19.6%). Whether receiving regular treatment, course of PHN, SDS score, physical exercise, sleep time and age were the main influencing factors of HRQOL. Conclusions Most patients with PHN suffer from depressive symptoms with poor HRQOL scores. Receiving early treatment with integrated traditional Chinese and western medicine, strengthening exercise, ensuring adequate sleep and receiving psychological counseling can significantly improve the HRQOL of PHN patients.
