Substance use disorders in hospitalized psychiatric patients: the experience of one psychiatric emergency service in Turin

Predictors of Length of Stay in an Inpatient Psychiatric Unit of a General Hospital in Perugia, Italy

The aim of this study was to understand which of a number of factors are most associated with psychiatric inpatient length of stay (LoS). We hypothesized that a longer LoS would be predicted by: older age, male gender, unmarried marital status, foreign nationality, more than one hospitalization, being hospitalized involuntarily, psychotic symptoms and behavioral dyscontrol at admission, discharge diagnosis of psychotic and personality disorders, not having a substance use disorder, treatment with more than one class of medications, and being discharged to a community residential facility. All admissions to the Psychiatric Inpatient Unit of Santa Maria della Misericordia, Perugia Hospital, Umbria, Italy, from June 2011 to June 2014, were included in a medical record review. Bivariate analyses were performed and a multiple linear regression model was built using variables that were associated (p < .05) with LoS in bivariate tests. The study sample included 1236 patients. In the final, most parsimonious regression model, five variables independently explained 18 % of variance in LoS: being admitted involuntarily, being admitted for thought disorders, not having a substance-related disorder, having had more than one hospitalization, and being discharged to a community residential facility. LoS on this inpatient psychiatric unit in Umbria was associated with a number of sociodemographic and clinical characteristics. Knowledge of these and other predictors of LoS will be increasingly important to, when possible, reduce the length of restrictive, costly hospitalizations and embrace community-based services.

Challenges in detecting and diagnosing substance use in women in the acute psychiatric department: a naturalistic cohort study

BACKGROUND

This study examines sex differences in substance use and substance use disorder in the acute psychiatric department, and possible interactions between sex and clinical and social factors associated with this phenomenon.

METHODS

Data concerning substance use were collected in a naturalistic cohort study (n = 384, 51.6% male, 48.4% female) in an acute psychiatric department. Recent intake of substances at admission, diagnosis of substance use disorder and demographic and socioeconomic information were recorded. At admission, serum and urine samples were analysed for substance use and breath analysis was performed for alcohol levels.

RESULTS

Twice as many men as women were diagnosed with substance use disorder, whereas there were no gender differences in the number of positive toxicology screenings. Toxicology screening revealed the use of non-prescribed medication with addiction potential in 40% of both female and male patients many of whom did not report this in the admission interview. A low level of education in men and absence of parental responsibility in women showed a statistically significant interaction with a current diagnosis of substance use disorder.

CONCLUSIONS

Despite no sex differences in positive toxicology screenings in the acute psychiatric department, twice as many men as women are diagnosed with substance use disorders. The use of prescription drugs with addiction potential was widely under-reported by both sexes, in patients with no prescriptions for the medications. Women with no parental responsibility are overrepresented among those diagnosed with substance use disorder, as are men with a low level of education.

TRIAL REGISTRATION

The study is registered with the ClinicalTrials.gov identifier NCT01415323.

Gender differences in 353 inpatients with acute psychosis: The experience of one Psychiatric Emergency Service of Turin

The aim of the study is to evaluate gender-related socio-demographic and clinical differences in a large sample of inpatients with schizophrenia spectrum disorder. A sample of 353 acute patients, consecutively hospitalized between January 2007 and December 2008 in the Psychiatric Emergency Service of the San Giovanni Battista Hospital, was recruited. Psychiatric assessment included the Clinical Global Impression Scale-Severity (CGI-S), the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment of Functioning (GAF). Differences between the groups were tested using chi-square test and ANOVA. Data were analyzed using a three-way MANOVA with the six BPRS scales with repeated measures for admission/discharge and BPRS total score baseline and independent groups for men and women. A two-way ANOVA for repeated measures was performed for CGI-S and GAF. Men were younger, more likely to be never married, more often substance abusers. Male patients showed both lower anxious-depressive and anergia symptom scores and higher activation symptom scores than female patients. Brief hospitalization was shown to be highly effective in both groups. Females showed a significantly better improvement in anergia and activation than males. The present evidence suggests that management of acute psychosis should target specific gender differences which should influence therapeutic approach in all its modalities.
