The Hospital de Clínicas de Porto Alegre (HCPA), a public teaching hospital, has a Hospital-based Health Technology Assessment (HB-HTA) unit to support the decision-making process on technology incorporation, rationalization or disinvestment. In 2017, the plastic adhesive drape was standardized at HCPA for use in cardiovascular, digestive, orthopedic, and neurological surgery for the purpose of preventing surgical site infection (SSI). This study evaluated whether the plastic adhesive drape technology is more effective than the no adhesive drapes in the surgical procedures in which it is used in the HCPA, so as to support the medical board's decision regarding the rationalization of use.

The primary outcome was the surgical site infection rate (SSI). Searches were performed in PubMed, Cochrane and national and international health agencies: World Health Organization (WHO), National Institute for Health and Care Excellence (NICE), Centers for Disease Control and Prevention (CDC), Society for Healthcare Epidemiology of America (SHEA), Brazilian National Commission for the Incorporation of Technologies (CONITEC) and Brazilian National Health Surveillance Agency (ANVISA) databases. The search strategy combined terms related to the technology and types of surgery in which it is used in the HCPA. The quality of the included studies was assessed. Additionally, data on technology utilization and costs in the hospital were analyzed.

Technology assessment followed AdHopHTA project recommendations. Data from the hospital showed that the technology has been used in fifteen surgical specialties, different from the proposed incorporation, with a progressive increase in consumption from 2017 to 2018. The literature review included a systematic review with seven clinical trials, which concluded that the plastic adhesive drape lacks benefits, with potential for increased risk of SSI. The evidence was of moderate quality.

The expenses associated with the use of the technology were considered unjustified as it is not reimbursed by the Brazilian Ministry of Health and its disinvestment was recommended. The Medical Board approved the disinvestment of the technology based on the evidence found by the HB-HTA unit, and the medical staff complied with the decision.
