Audits are essential for reviewing and improving the medication-use process. Identifying areas for improvement can limit the risk of errors when preparing and administering drugs. Pediatric centers face specific challenges in ensuring the safety of the medication-use process. The objective of this study was to observe and compare compliance with criteria for the preparation and administration of medications by nurses in a mother-and-child university hospital center over two consecutive years.

This observational cross-sectional study was conducted in a Canadian mother-and-child university hospital center. Audits were conducted over a 1-month period in 16 and 18 nursing care sectors in 2021 and 2022, respectively. The standardized audit evaluated compliance with prespecified criteria related to the preparation and administration of medication by nursing staff (77 criteria for 2021 and 82 criteria for 2022). The auditors comprised nurses and a pharmacist trained by the research team. Compliance was compared between years and assessed through a chi-square test.

The audit consisted of 522 observations in 2021 and 448 observations in 2022. Overall compliance was 76% in 2021 and 66% in 2022. The compliance rate by criterion ranged from 16% to 100%. In 2021 and 2022, 51 (84%) and 52 (87%) of the criteria, respectively, had compliance rates of more than 75%, and 12 (20%) and eight (13%), respectively, had 100% compliance. There were statistically significant decreases in compliance for nine of the 39 criteria for preparation of medications, notably prior hand hygiene (91%% vs. 84%, p = 0.002), and for six of the 17 criteria for administration of medications, including mentioning possible adverse effects to the patient (41% vs- 30%, p = 0.008).

In this study, compliance was over 75% for most of the criteria. However, for a few criteria, we observed a decrease in compliance from 2021 to 2022. Various hypotheses are proposed to explain these decreases, such as the COVID-19 pandemic.
