Hand hygiene (HH) is a cornerstone of programmes to prevent healthcare associated infections (HAI) globally, but HH interventions are seldom reported from African neonatal units.
We conducted a quasi-experimental study evaluating the impact of a multi-modal intervention (SafeHANDS) on HH compliance rates, alcohol-based handrub (ABHR) usage, the Hand Hygiene Self-Assessment Framework (HHSAF) score, and healthcare-associated bloodstream infection (HA-BSI) rates at a 132-bed South African neonatal unit (4 wards and 1 neonatal intensive care unit [NICU]). The intervention included a campaign logo, HH training, maternal education leaflets, ABHR bottles for staff, and the setting of HH performance targets with feedback. Three 5-month study phases were completed in July 2020 (baseline), December 2020 (early) and May 2021 (intensive).
A total of 2430 HH opportunities were observed: 1002 (41.3%) at baseline, 630 (25.9%) at early and 798 (32.8%) at intensive study phases. At baseline, the overall neonatal unit HH compliance rate was 61.6%, ABHR use was 70 mL/patient day, and the baseline HHSAF score was 'basic' (165). The overall neonatal unit HH compliance rate was unchanged from baseline to intensive phases (617/1002 [61.6%] vs. 497/798 [62.3%]; = 0.797). The ABHR use remained similar between phases (70 versus 73 mL/patient day). The HHSAF score improved to 'intermediate' level (262). There was no change in the neonatal unit HA-BSI rate.
Despite improvement in the HHSAF score, no improvement in overall HH compliance rates, ABHR usage, or HA-BSI rates was observed. Future HH interventions in resource-limited neonatal units should incorporate implementation science and behaviour modification strategies to better understand the barriers and facilitators of HH best practice.
手部卫生(HH)是全球预防医疗相关感染(HAI)项目的基石,但非洲新生儿病房很少报告手部卫生干预措施。
我们进行了一项准实验研究,评估多模式干预措施(SafeHANDS)对南非一家拥有132张床位的新生儿病房(4个病房和1个新生儿重症监护病房[NICU])的手部卫生依从率、酒精擦手液(ABHR)使用情况、手部卫生自我评估框架(HHSAF)评分以及医疗相关血流感染(HA-BSI)发生率的影响。该干预措施包括一个活动标志、手部卫生培训、产妇教育传单、给工作人员配备ABHR瓶,以及设定手部卫生绩效目标并提供反馈。2020年7月(基线期)、2020年12月(早期)和2021年5月(强化期)完成了三个为期5个月的研究阶段。
共观察到2430次手部卫生机会:基线期1002次(41.3%),早期630次(25.9%),强化研究阶段798次(32.8%)。基线期,新生儿病房总体手部卫生依从率为61.6%,ABHR使用量为70毫升/患者日,基线HHSAF评分为“基本”(165分)。从基线期到强化期,新生儿病房总体手部卫生依从率没有变化(617/1002[61.6%]对497/798[62.3%];P = 0.797)。各阶段之间ABHR使用量保持相似(70对73毫升/患者日)。HHSAF评分提高到了“中级”水平(262分)。新生儿病房HA-BSI发生率没有变化。
尽管HHSAF评分有所提高,但总体手部卫生依从率、ABHR使用量或HA-BSI发生率均未改善。未来在资源有限的新生儿病房进行手部卫生干预时,应纳入实施科学和行为改变策略,以更好地了解手部卫生最佳实践的障碍和促进因素。
