Objectives: To describe a cohort of inpatients observed by a Liaison Psychiatry Unit.
Background: Psychiatric symptomatology is common among patients admitted for non-psychiatric diagnosis. Liaison psychiatry has a fundamental role on the evaluation and approach of these patients. An in-depth knowledge of this population may help improve healthcare and reduce morbidity.
Materials and Methods: Retrospective and observational study. Review of clinical processes of patients observed in psychiatry internal consultation from August 2018 to January 2019. Statistical analysis with SPSS® V20.
Results: We included 232 patients, 119 male (51,3%) with mean age of 55,7 years (SD ± 15,3). One hundred and seventeen patients (50,4%) had a previous psychiatric diagnosis and 43 (18,5%) had a history of previous admission to a psychiatric inpatient unit.
More frequently, requests were made by the departments of Internal Medicine (12,1%), Hematology (10,3%) and Infectious Diseases (9,9%). Most common reasons for referral were depressive symptomatology (23,7%), psychomotor agitation (15,1%) and history of a previous psychiatric diagnosis (11,2%).
After evaluation, most common diagnosis were Adjustment Disorders (20,3%) and Depressive Disorders (19,0%) and Delirium (12,9%). Thirty patients (12,9%) had no psychiatric diagnosis. Psychiatric medication was started in 97 patients (41,8%) and posology adjusted in 64 patients (27,6%). Psychology support was requested in 39 patients (16,8%). After discharge, 100 patients (43,1%) were referenced to psychiatry consultation and 93 patients (40,1%) kept monitoring in primary care.
Conclusions: Most inpatients referred to liaison psychiatry have significant psychopathology requiring intervention. A timely observation allows an adequate management and referral for outpatient monitoring.
