Infectious healthcare waste management among private dental practitioners in the Rabat-Salé-Kénitra region, Morocco: A cross-sectional study on knowledge, attitudes, and practices

The increase in dental healthcare facilities and the use of single-use equipment have increased the production of healthcare waste. Their mismanagement exposes healthcare workers, waste managers, and the population to an infectious risk and negatively impacts the environment. Therefore, a correct management procedure has to be adopted from separation through storage to disposal. This study aimed to investigate dentists' knowledge, attitudes, and practices regarding managing infectious healthcare waste in private dental offices. A descriptive and analytical cross-sectional survey was conducted between December 2020 and March 2021 among private dentists registered at the Moroccan National Council of Dentists in the Rabat-Salé-Kénitra region. A questionnaire was developed to assess waste management in dental offices. Of the 500 questionnaires distributed, 190 completed and exploitable questionnaires were collected. Only 27.3% of healthcare waste managers in dental practices received training, 21,5% of practitioners assimilated the used gloves into household waste, 71.5% disposed of the waste generated by their offices directly into public bins, and 86.4% were unaware of Moroccan law 28-00 on waste management and disposal. This study highlights dentists' apparent lack of knowledge regarding healthcare waste management, and significant gaps were identified between actual practices and recommended regulations. To address these issues, developing a comprehensive medical waste management plan is crucial to encourage the practical cooperation of all stakeholders in this sector.
