The differences between referred and non-referred patients to a psychiatric consultation-liaison service in a general hospital

Abstract

Objective The primary aim of this study was to investigate whether there are clinical differences between patients who are referred or not referred for psychiatric consultation and liaison service. The secondary aim was to compare the perspectives of doctors, nurses and patients. Methods This naturalistic, prospective and comparative study (N = 294) utilised a control sample of non-referrals (n = 177, consenting 81) and referrals (n = 177, consenting 49). The normality of the data was examined with the Shapiro-Wilk test; bivariate group comparisons were made using Mann-Whitney, Wilcoxon tests and bivariate regression analyses. Statistically adjusted group comparisons were performed with multivariate median regressions. Results The sample presented limited representativeness. Referred patients were predominantly women, mostly living alone and not working. Compared to the non-referred patients, their disease episode and length of hospital stay were significantly longer, self-efficacy and quality of life lower and psychological stress was higher. For referred patients, there were no differences between the estimations of mental burden and the need for care among doctors, nurses and patients. Self-efficacy and appraisal of one's own burden were the best predictors of the extent of mental symptoms. Discussion Patients in an admission ward for internal medicine referred to a psychiatric consultation-liaison service displayed a more adverse psychosocial profile and were more psychologically burdened than non-referred patients, but they are also relevantly subsyndromal burdened. Identifying and supporting burdened patients is an endeavour that requires collaborative care, especially in the transition to specialised mental health and to primary care.
