Adverse effects of isolation: a prospective matched cohort study including 90 direct interviews of hospitalized patients in a French University Hospital.

Isolation precautions in patients with multi-drug resistant bacteria or other communicable infectious agents can be associated with adverse effects. The aim of this study was to assess satisfaction and psychological impact of patients hospitalized with isolation precautions in comparison with controls. An observational prospective cohort study was performed in five different medical and surgical departments in a 3,000-bed university hospital in Western France between March and July 2012. Different scales were used to assess patient satisfaction (qualitative scale) and anxiety (Spielberger scale), including 30 patients with isolation precautions and 60 matched patients without isolation precautions over 45-hour interviews. Cases were significantly less satisfied than controls for healthcare workers (HCW) assistance in activities of daily life (p < 0.001), availability and relationships (17 % vs 5 %, p = 0.05 and 10 % vs 0%, p = 0.02, respectively). Sixty-seven percent of patients with isolation precautions were not satisfied about the quality of the information related to their infectious status control measures. The median score [range] of anxiety significantly was higher in patients with isolation precautions (52 [20-56] vs 31 [23-73], p <0.001). Isolation precautions may have negative psychological effects, leading to anxiety, and may compromise patient satisfaction according to the availability and relationship with HCW. Professionals should be aware of adverse effects of isolation and inform patients more actively with regard to their infectious status and precautions.
