Variables associated with compliance with standard precautions among hospital nurses: a systematic review and...

This study aimed to conduct a systematic review and meta-analysis to identify variables associated with standard precautions compliance among hospital nurses and to comprehensively examine their effect sizes.

A systematic review and meta-analysis were reported in accordance with the PRISMA and MOOSE guidelines. Studies published in English or Korean were retrieved from KMbase, KoreaMed, KISS, ScienceON, RISS, Nanet, DBpia, PubMed, Embase, CINAHL, and CENTRAL. Data collection was conducted from July 6 to July 16, 2024. To ensure a comprehensive search, no restrictions were placed on the publication period, and studies published up to June 2024 were included in the literature search. Analyses were performed using R ver. 4.4.1.

Of the 2,321 studies screened, 50 were included in the systematic review and 41 were included in the meta-analysis. Variables were categorized according to the ecological model. Among individual-level factors, variables with medium correlation effect sizes (ESr ≥.30) included self-efficacy (ESr=.41; 95% confidence interval [CI], 0.24 to 0.56), perceived barriers (ESr=-.35; 95% CI, -0.59 to -0.05), cues to action (ESr=.34; 95% CI, 0.07 to 0.57), and perceived benefits (ESr=.30; 95% CI, 0.13 to 0.46). Among organizational factors, organizational culture for infection control (ESr=.47; 95% CI, 0.39 to 0.54) and patient safety culture (ESr=.44; 95% CI, 0.35 to 0.53) demonstrated medium effect sizes. Other statistically significant variables with small effect sizes were also identified. No variables were identified within the interpersonal, community, or public policy domains.

This study identified self-efficacy and organizational culture for infection control as key determinants of compliance with standard precautions. Strengthening these factors may reduce healthcare-associated infections and promote safer nursing care (PROSPERO registration number: CRD42024566518).
