A framework for the implementation of consultation-liaison psychiatry from the characteristics of psychosomatic consultations at a general hospital in China

Objective To describe the characteristics of a consultation-liaison psychiatry (CLP) service at a general hospital in China, compare the literature on CLP in other hospitals in China and abroad, and identify reasons for the differences. Methods The medical records of all inpatients who received liaison consultations in the first year of the establishment of Xi’an International Medical Center Hospital were reviewed. Demographic data, specific department, number of consultations, reasons for consultation, outcome of consultation, and follow-up information on patients was collected. Results A total of 630 patients were enrolled during the first year of the hospital’s opening, of which 45.2% were male and 54.8% were female. A total of 89.2% of non-psychiatric departments requested a psychosomatic consultation. The percentage of middle-aged and elderly patients was 75.6%, of whom 61.6% were aged 45 to 74 years. The internal medicine department requested the highest number of consultations (48.2%), including those from respiratory medicine (12.1%), neurology (12.1%), gastroenterology (12.1%), and cardiology (12.1%). Among surgical patients, orthopedic patients (6.5%) comprised the majority of consults. The main reasons for requesting a psychosomatic consultation were depressive symptoms (139 cases, 22.8%), anxiety symptoms (137 cases, 22.5%), sleep problems (111 cases, 18.2%), and hallucinations, delusions, or behavioral problems (68 cases, 11.2%), accounting for a total of 74.6% of consultations (455/630). Conclusion A significant gap exists between the level of CLP services in China and developed regions in Europe and the United States, mainly due to low psychiatric consultation rates and poor quality CLP services.
