We evaluated the role of the BPRS-E in predicting inpatient length of stay in a sample of patients that was representative of the psychiatric population in the town of Ferrara, Northern Italy. The study participants were patients who were consecutively admitted to the only residential facility for short- to medium- term psychiatric care in the town during a 14-month period. Upon the patient’s admission, we documented sociodemographic and clinical data, ICD-10 psychiatric diagnosis, and duration of illness. The BPRS-E was administered by the first author. The BPRS-E items were subjected to a principal-components analysis with varimax rotation and Kaiser normalization. Factorial analysis produced six BPRSE factors. Factor 1 (positive symptoms) included grandiosity, suspiciousness, hallucinations, unusual thought content, bizarre behavior, mannerisms and posturing, and conceptual disorganization. Factor 2 (manic symptoms) included elevated mood, disorientation, tension, excitement, distractibility, and motor hyperactivity. Factor 3 (negative symptoms) included self-neglect, blunted affect, emotional withdrawal, and motor retardation. Factor 4 (depressive symptoms) included depression, suicidality, and guilt. Factor 5 (patients’ resistance to treatment) included hostility and uncooperativeness. Factor 6 (anxiety symptoms) included somatic concern and anxiety. The results of the bootstrap linear regression analysis showed that demographic and clinical variables were not associated with length of stay and that negative symptoms were positively associated with length of stay (coefficient=3.28, bias-corrected 95 percent CI=.96 to 5.93, p<.05; 22 percent of the variance explained). Age, sex, living conditions, duration of illness, diagnosis, and number of previous admissions were not associated with length of stay, thus giving further relevance to the possibility of predicting length of stay by administering the BPRS-E upon patient admission.

Abstract

We evaluated the role of the BPRS-E in predicting inpatient length of stay in a sample of patients that was representative of the psychiatric population in the town of Ferrara, Northern Italy. The study participants were patients who were consecutively admitted to the only residential facility for short- to medium- term psychiatric care in the town during a 14-month period. Upon the patient’s admission, we documented sociodemographic and clinical data, ICD-10 psychiatric diagnosis, and duration of illness. The BPRS-E was administered by the first author. The BPRS-E items were subjected to a principal-components analysis with varimax rotation and Kaiser normalization. Factorial analysis produced six BPRSE factors. Factor 1 (positive symptoms) included grandiosity, suspiciousness, hallucinations, unusual thought content, bizarre behavior, mannerisms and posturing, and conceptual disorganization. Factor 2 (manic symptoms) included elevated mood, disorientation, tension, excitement, distractibility, and motor hyperactivity. Factor 3 (negative symptoms) included self-neglect, blunted affect, emotional withdrawal, and motor retardation. Factor 4 (depressive symptoms) included depression, suicidality, and guilt. Factor 5 (patients’ resistance to treatment) included hostility and uncooperativeness. Factor 6 (anxiety symptoms) included somatic concern and anxiety. The results of the bootstrap linear regression analysis showed that demographic and clinical variables were not associated with length of stay and that negative symptoms were positively associated with length of stay (coefficient=3.28, bias-corrected 95 percent CI=.96 to 5.93, p<.05; 22 percent of the variance explained). Age, sex, living conditions, duration of illness, diagnosis, and number of previous admissions were not associated with length of stay, thus giving further relevance to the possibility of predicting length of stay by administering the BPRS-E upon patient admission.
