Nosocomial pathogens are transmitted by contamination of surfaces causing healthcare-associated infections (HAI). The impact of locally produced disinfectant with operational training as a means to improve hygiene in resource-limited healthcare facilities and prevent HAI was evaluated.
In Burkina Faso, 4 types of electro-chlorinator devices that convert salt and water into sodium hypochlorite through electrolysis were installed in 26 healthcare facilities distributed across 3 sanitary districts. The program was evaluated at 4 months and 11 months and performance compared with a control group.
After 11 months, over 90% of the facilities applied 8 of the 11 essential hygiene practices defined by the Ministry of Health, compared to 20% in the control group. 61.5% of the healthcare facilities improved the chlorine concentration of their sodium hypochlorite solutions, reaching an average concentration of 5.1 g/L compared to an average of 2.1 g/L in the control group. Additionally, a cost-benefit analysis demonstrated that locally produced sodium hypochlorite led to daily savings ranging between 2.7 and 53 euros depending on the device compared with the purchase of chlorine tablets.
Results, therefore, suggest that electro-chlorinator devices in addition to hygiene sensitization can be a simple, cost-effective and tailored intervention to reduce the prevalence of HAI in low-resource settings.
医院病原体通过表面污染传播,导致医疗保健相关感染(HAI)。评估了本地生产的消毒剂结合操作培训作为改善资源有限的医疗机构卫生状况和预防HAI的手段的影响。
在布基纳法索,将4种通过电解将盐和水转化为次氯酸钠的电解氯化器设备安装在分布于3个卫生区的26家医疗机构中。在4个月和11个月时对该项目进行评估,并与对照组比较性能。
11个月后,超过90%的设施实施了卫生部定义的11项基本卫生措施中的8项,而对照组为20%。61.5%的医疗机构提高了其次氯酸钠溶液的氯浓度,平均浓度达到5.1克/升,而对照组平均为2.1克/升。此外,成本效益分析表明,与购买氯片相比,本地生产的次氯酸钠根据设备不同每天可节省2.7至53欧元。
因此,结果表明,除了卫生宣传外,电解氯化器设备可以是一种简单、经济高效且量身定制的干预措施,以降低资源匮乏地区HAI的患病率。
