Effects of acute-phase monotherapy and combination therapy on quality of life in patients with depressive disorders / 四川精神卫生

ABSTRACT

BackgroundThe treatment of patients with depressive disorders is short of targeted outcome assessment. As a secondary outcome that is guided by patient values， quality of life is thus of relatively high evaluative value. In China， there exists a lack of large sample prospective cohort studies evaluating the effect of different treatment protocols on quality of life in patients with acute depressive disorder. ObjectiveTo explore the effects of monotherapy and combination therapy on the quality of life of patients with depressive disorder in acute phase， so as to provide references for optimizing the outcome of treatment for such patients. MethodsA prospective follow-up cohort study from August 24， 2020 to November 29， 2021 was conducted， including 1 330 patients from 22 hospitals across 18 cities in China. All these patients met the diagnostic criteria for depressive episodes， recurrent depressive disorder from the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. Patients were divided into monotherapy group （n=969） and combination therapy group （n=361） according to the acute phase treatment protocol. At baseline， the end of the first half month as well as the 1st， 2nd， 3rd， 6th， 9th and 12th months of treatment， patients were assessed with Inventory of Depressive Symptomatology Self-report （IDS-SR30）， Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form （Q-LES-Q-SF）， Concise Health Risk Tracking Scale （CHRT） and Siehan Disability Scale （SDS）. Frequency， Intensity， and Burden of Side Effects Rating （FIBSER） was adopted for assessment at each visit time point of treatment. Spearman correlation analysis was adopted to examine the correlation of quality of life with suicide risk， adverse reactions and impaired social functioning among patients. ResultsAt the end of three months of treatment， the Q-LES-Q-SF score of monotherapy group was higher than that of combination therapy group， and the difference was statistically significant （Z=2.008， P<0.05）. The time effects of both treatment protocols possessed statistical significance （F=111.393， P<0.01）. At the end of three months of treatment， the Q-LES-Q-SF score was negatively correlated with CHRT and SDS scores， respectively， in both monotherapy group and combination treatment group （r=-0.660， -0.712， -0.634， -0.718， P<0.01）. ConclusionBoth monotherapy and combination therapy can facilitate the improvement of the life quality of patients with acute depressive disorder， but monotherapy may achieve better than the combination therapy in this aspect. ［Funded by The National Key Research and Development Program of China "Research on the Prevention and Control of Major Chronic Non-communicable Diseases" （number， 2017YFC1311101）］
