ABSTRACT
Introduction: Cannabis-induced psychotic disorder (CIPD) is defined by the development of psychotic symptoms during or briefly after intoxication with cannabis or withdrawal from cannabis. The social measures and restrictions implemented following the COVID-19 pandemic might have had an impact on cannabis availability, as suggested by patients from our clinical practice, reporting a shortage of the substance. Objective(s): To compare sociodemographic, clinical characteristics and admission rates of inpatient treatment for cannabis-induced psychotic disorder in COVID-19 pandemic period and prepandemic period. Method(s): Retrospective observational study of inpatient admissions for CIPD in a psychiatry inpatient unit of a tertiary hospital. The statistical analysis was performed using SPSS software, version 27.0. Result(s): Our sample included 120 inpatient admissions, corresponding to 80 patients. Compared to 2018 and 2019, in 2020 there was an overall reduction of 21.5% in inpatient admissions (n=618, 549 and 458, respectively). The number of admissions for CIPD in 2018, 2019, 2020 and 2021 up to september were, respectively, 29, 32, 10 and 31 (5.2%, 6.1%, 2.2% and 7.2% of respective annual admissions). We found no statistically significant differences regarding sociodemographic and clinical characteristics in patients admitted for CIPD during 2020. Conclusion(s): These results suggest a disproportionate reduction of inpatient admissions due to CIPD in 2020, followed by an expressive increase in the number of admissions in 2021up to september. This might be related to cannabis availability returning to regular levels. However other factors must be considered, such as the delay of treatment due to reduced accessibility to health care.
ABSTRACT
IntroductionCOVID-19 pandemic and the consequent containment measures have a negative impact on mental health. Simultaneously, the fear of infection can discourage patients from seeking necessary care.ObjectivesWe aim to compare sociodemographic and clinical characteristics of inpatients admitted during the COVID-19 confinement period in Portugal vs. inpatients admitted in the same period the previous year.MethodsRetrospective observational study of inpatients admitted between March 19th 2020 and May 1st 2020 and the analog period of 2019 in a psychiatry inpatient unit of a tertiary hospital. Descriptive analysis of the results was performed using the SPSS software, version 26.0.ResultsDuring the lockdown period, there were 30 admissions to the psychiatry inpatient unit, 55.2% less than the same period last year (n=67). The proportion of compulsory admissions and the average length of stay did not differ between the two periods. Regarding sociodemographic characteristics, in the confinement period inpatients were similar to the ones in the same period of 2019. In both periods, the majority of patients had previous psychiatric history (lockdown vs. same period last year: 95.5% and 90.0%) and a similar proportion of readmissions rate (previous year) was similar in the two groups (49.9% vs 47.6%). At discharge, the most frequent diagnostic groups were mood disorders (33.3% (n=10) and 34.3% (n=23)) and schizophrenia, schizotypal and delusional disorders (26,7% (n=8) and 31.3% (n=21)).ConclusionsAlthough there was an expressive reduction of admissions to the psychiatry inpatient unit during lockdown, the clinical characteristics of these patients were analogous to the same period in the previous year.
