Waste Manag Res. 2022 Jul;40(7):1085-1089. doi: 10.1177/0734242X211046853. Epub 2021 Sep 18.
The COVID-19 pandemic has created unprecedented difficulties for health care institutions, which are required to manage not only the flow of patients with COVID-19, but also the management of medical and pharmaceutical waste (MPW). At the level of Morocco, the waste produced by hospitals has risen sharply in the regions most affected by the virus, such as the Rabat-Sale-Kenitra region (15.05% of recorded cases). The objective of this study is to perform a descriptive statistical analysis and to evaluate the generation rates of MPW generated during the treatment of the coronavirus pandemic, with reference to a large health care hospital in the region, in order to enable decision-makers to adopt responses in terms of regular and continuous management of MPW. The Moulay Abdellah hospital in Sale has a bedding capacity allocated to the COVID-19 patient of 110 beds with a Average Occupation Rate (AOR) of 100% and an average production of 13tons per month. The study showed that the average rate of MPW generated is 4 kg per bed per day, which is twice as high as the average generation rate during normal operation in 2019. As well, frequency analysis of the data revealed that MPW generation follows a log normal distribution with a correlation coefficient of 0.9. The distribution is skewed to the right and flatter than the normal distribution curve as judged by the skewness coefficient which is 0.87 and kurtosis coefficient which has a value of 1.286, indicating a deviation from normality.
新冠疫情给医疗机构带来了前所未有的困难，这些机构不仅要管理新冠患者的流量，还要管理医疗和制药废弃物（MPW）。在摩洛哥层面，医院产生的废弃物在受病毒影响最严重的地区大幅增加，比如拉巴特-萨勒-凯尼特拉地区（占记录病例的15.05%）。本研究的目的是进行描述性统计分析，并参照该地区一家大型医疗医院，评估在新冠疫情治疗期间产生的MPW的产生率，以便决策者能够在MPW的定期和持续管理方面采取应对措施。萨勒的穆莱·阿卜杜拉医院为新冠患者分配的床位容量为110张，平均占用率（AOR）为100%，每月平均产量为13吨。研究表明，MPW的平均产生率为每张床位每天4千克，这是2019年正常运营期间平均产生率的两倍。此外，数据的频率分析显示，MPW的产生遵循对数正态分布，相关系数为0.9。根据偏度系数0.87和峰度系数1.286判断，该分布向右偏斜且比正态分布曲线更扁平，表明偏离了正态性。
