How did the COVID-19 lockdown impact patients with dual diagnoses?

ABSTRACT

Purpose: Individuals with dual diagnoses might experience significant clinical and social vulnerabilities during the pandemic and lockdown. This study aims to compare medication adherence, substance use, clinical stability and overall functioning before and during lockdown periods. Design/methodology/approach: This was a cross-sectional survey among patients registered in dual diagnosis clinic of an addiction psychiatry center in Northern India between March 2019 and February 2020. This study approached 250 patients for telephonic interviews. This study assessed adherence to medications with the brief adherence rating scale (BARS). Global functioning was measured by global assessment of functioning. Clinical interviews assessed substance use and the clinical status of psychiatric disorders. Findings: One hundred fifty patients were recruited. The mean age of the sample was 35.8 years. The sample had a slight preponderance of alcohol dependence. Depressive disorder was the largest category of psychiatric diagnosis. Compared to prelockdown period, during the lockdown, there were an increased number of days of nonadherence (X2 17.61, p < 0.05), proportion of patients underdosing (X2 8.96, p = 0.003) and lower BARS scores (t = 10.52, df = 144, p < 0.0001). More patients were abstinent from substances during the lockdown (X2 49.02, p < 0.0001). Clinical stability of psychiatric disorders did not differ during the two-time points, but overall functioning decreased during the lockdown (t = 2.118, p = 0.036). This study observed a small positive correlation (r = 0.2, p = 0.02) between functioning and adherence levels. Originality/value Lockdown was associated with poor medication adherence, change in substance use patterns and functional impairment. In the future, treatment programs and policies must take preemptive steps to minimize the effects of restrictions. © 2022, Emerald Publishing Limited.
