Homogeneity of pharmacological prescription and control measures applied in cases of scabies detected amongst inmates in Catalonia.

Abstract

Objectives: To review the homogeneity of pharmacological prescription and control measures applied in cases of scabies in prisons in Catalonia.

Material and method: Observational, multicenter, and retrospective study. Cases of scabies from March 01, 2021 and March 01, 2022 were analyzed according to the International Alliance for the Control of Scabies (IACS) 2020 criteria: a) confirmed cases; b) clinically probable cases; and c) suspected cases.Epidemiological, clinical, therapeutic and regimental control variables were collected. We checked whether the interventions were homogeneous in each site. The mean and standard deviation were used as continuous variables and percentages and confidence interval (95%) for discrete variables. The Chi-square test was used to determine statistical association.

Results: 269 cases were detected (21.2% confirmed, 50.2% clinically probable and 28.6% suspected). 61.3% were treated with permethrin, 18.6% with ivermectin and 20.1% with both. 27.1% of the cases were withdrawn.There were no significant in-site differences in the study of contacts, isolation and treatment of clothing and belongings, but there were significant differences in the prescription of drugs (P <0.001), duration of treatment (P <0.001) and disinfection of the cell (P <0.001).

Discussion: The number of detected cases is estimated to be high, and the majority (71.4%) confirmed or clinically probable. Control measures are homogeneous, except for cell disinfection, which was conventional in 59.1%. Pharmacological treatment and its duration varied between prisons. It would be advisable to establish a protocol to standardize control measures applied to new cases in the centers of Catalonia and subsequently evaluate their efficacy.
