This study aimed to develop the Failure Mode and Effects Analysis (FMEA) and Decision Matrix Risk Assessment (DMRA) technique for the first time to assess risks associated with particulate matter (PM) and bioaerosol transmission in hospitals. The risks were prioritized by calculating the Risk Priority Number (RPN). Control measures were suggested to mitigate indoor air pollution. In this study, a group of healthcare experts was selected to form an assessor team from four hospitals in Iran. The validity and reliability of the FMEA checklist were assessed using the Intra-class Correlation Coefficient (ICC) and Cronbach Alpha coefficients. The data was collected and reported in checklist format. The Cronbach Alpha and ICC coefficients in the study were 0.619 and 0.913, respectively, confirming the validity of the FMEA model for assessing indoor pollutants in hospitals. The RPN ranged from 36 to 468 for the 19 identified risks.•First-time application of FMEA model and DMRA risk assessment for indoor pollutants were developed•The validity of the FMEA model was confirmed for hospitals' indoor pollutants risk assessment•Risk priorization and control measures were proposed to mitigate indoor air pollution effects by developing the DMRA technique.
本研究旨在首次开发失效模式与效应分析（FMEA）和决策矩阵风险评估（DMRA）技术，以评估医院中与颗粒物（PM）和生物气溶胶传播相关的风险。通过计算风险优先数（RPN）对风险进行优先级排序。建议采取控制措施以减轻室内空气污染。在本研究中，从伊朗的四家医院中挑选了一组医疗保健专家组成评估团队。使用组内相关系数（ICC）和克朗巴哈α系数评估FMEA检查表的有效性和可靠性。数据以检查表格式收集和报告。本研究中的克朗巴哈α系数和ICC系数分别为0.619和0.913，证实了FMEA模型在评估医院室内污染物方面的有效性。对于识别出的19种风险，RPN范围为36至468。
