Objective To understand the current situation and characteristics of consultation-liaison psychiatry (CLP) service in general hospital, to compare the results of the literature on CLP published in other hospitals in China and abroad, and to find deficiencies for the current differences. Methods The medical records of all inpatients who had liaison consultations in the first year of the establishment of Xi'an International Medical Center Hospital, China, were collected. Statistical analysis was performed on the general demographic data, department origin, number of consultations, the reason for consultation, diagnosis of consultation, and follow-up of patients. Results A total of 630 patients were enrolled in the past 1 year, of which, 45.23% were males and 54.8% were females. 89.2% of non-psychiatric departments applied for psychosomatic consultation. The percentage of middle-aged and elderly patients was 75.6%, including 61.6% of patients aged 45−74 years. The internal medicine department had the highest number of consultations (48.2%), including respiratory medicine (12.1%), neurology (12.1%), gastroenterology (12.1%), and cardiology (12.1%). For surgical patients, orthopedic patients (rehabilitation, 6.5%) comprised the majority of consults. The main reasons for requesting psychosomatic consultations included depressive symptoms (139 cases, 22.8%), anxiety symptoms (137 cases, 22.5%), sleep problems (111 cases, 18.2%), as well as hallucinations and delusions or behavioral disorders (68 cases, 11.2%), accounting for a total of 74.59% (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 consultation rates and referrals and imperfect CLP service.
