Abstract
BACKGROUND: Quality improvement (QI) methods are recommended to address healthcare-associated infections (HCAIs) in hospitals, but whereas internal initiatives have been widely studied, there is little evidence on the application and effect of a QI approach from an external system-wide perspective. AIM: To analyse the effect of a national system-wide QI initiative aimed at promoting HCAI prevention via regulatory interventions in Brazil. METHODS: A QI cycle approach designed and assessed with a before-and-after quasi-experimental design was implemented by the Brazilian Health Regulatory Agency (ANVISA), targeting 1869 hospitals. Eleven evidence-based quality indicators related to HCAI prevention and a composite measure were assembled, shared, and assessed; the intervention to improve was then based on participatory multifaceted regulatory actions. Absolute and relative improvements were estimated after the intervention. FINDINGS: In all, 563 hospitals (30.1% response) totalling 86,837 beds participated in the baseline assessment, and 681 hospitals (36.4% response) totalling 101,231 beds in the second. Ten of the 11 criteria improved (P < 0.05), as well as the composite indicator (P = 0.001) in all the regions of the country, particularly in the group of hospitals participating at baseline. 'Hand hygiene (HH) infrastructure' reached 100% (baseline: 97.9; P = 0.001), 'HH protocol' 96.9% (baseline: 92.9; P = 0.001), 'HH monitoring' 70% (baseline: 60.7; P < 0.001) and 'existence of antimicrobial prescription protocol' 80.7% (baseline: 73.2; P < 0.001), among others. The HCAI rates of the participating hospitals decreased after the intervention (P < 0.05). CONCLUSION: The QI cycle approach was useful in guiding system-wide interventions for patient safety. External regulation was feasible and effective in promoting internal HCAI prevention nationwide.
