Introduction Many patients suffering from serious mental illness experience severe anxiety and those with psychosis often report the feeling of their bodies falling apart. While it is believed that these patients benefit from therapeutic body wraps (TBWs), the use of this adjunct therapy has rarely been studied in adult patients. Aims The aim of this study was to obtain descriptive statistics on the clinical, social-demographic and institutional reality of TBW therapy in Swiss public adult inpatient wards. Methods Retrospective data related to a cohort of 172 adult inpatients were retrieved from records of two public hospitals. Correlations between TBW and the prescriptions of lorazepam were explored. Results TBWs were primarily used for patients diagnosed with either schizophrenia, schizotypal, delusional and other non-mood psychotic disorders or mood disorders. Patients had, on average, four psychiatric hospitalizations, and in 30% of the cases, TBWs were offered during the first hospitalization. Moreover, TBWs were mostly practiced by nurses. Body wraps were potentially associated with a reduction in both anxiolytic and neuroleptic drugs. Discussion/Implication for practice Based on our results, TBW might contribute to the clinical management of anxiety by nurses. The efficacy of TWB regarding anxiety has yet to be investigated in a randomized controlled trial.
