Quality improvement in the golden hour for premature infants: a scoping review

Abstract

Background and objective: Evidence-based research has shown that golden hour quality improvement (QI) measures can improve the quality of care and reduce serious complications of premature infants. Herein, we sought to review golden hour QI studies to evaluate the impact on the outcome of preterm infants. Methods: A comprehensive literature search was conducted in PubMed, Embase, Cochrane Library, and SinoMed databases from inception to April 03, 2023. Only studies describing QI interventions in the golden hour of preterm infants were included. Outcomes were summarized and qualitative synthesis was performed. Results: Ten studies were eligible for inclusion. All studies were from single centers, of which nine were conducted in the USA and one in Israel. Seven were pre-post comparative studies and three were observational studies. Most included studies were of medium quality (80%). The most common primary outcome was admission temperatures and glucose. Five studies (n = 2308) reported improvements in the admission temperature and three studies (n = 2052) reported improvements in hypoglycemia after QI. Four studies (n = 907) showed that the incidence of bronchopulmonary dysplasia (BPD) was lower in preterm infants after QI: 106/408 (26.0%) vs. 122/424(29.5%) [OR = 0.68, 95% CI 0.48–0.97, p = 0.04]. Conclusions: Our study showed that the golden hour QI bundle can improve the short-term and long-term outcomes for extremely preterm infants. There was considerable heterogeneity and deficiencies in the included studies, and the variation in impact on outcomes suggests the need to use standardized and validated measures. Future studies are needed to develop locally appropriate, high-quality, and replicable QI projects.
