Patient safety culture in maternity units: a review.

Abstract

Purpose: The purpose of this paper is to summarize studies that have examined patient safety culture in maternity units and describe the different purposes, study designs and tools reported in these studies while highlighting gaps in the literature.

Design/methodology/approach: Peer-reviewed studies, published in English during 1961-2016 across eight electronic databases, were subjected to a narrative literature review.

Findings: Among 100 articles considered, 28 met the inclusion criteria. The main purposes for studying PSC were: assessing intervention effects on PSC (n=17), and assessing PSC level (n=7). Patient safety culture was mostly assessed quantitatively using validated questionnaires (n=23). The Safety Attitude Questionnaire was the most commonly used questionnaire (n=17). Interventions varied from a single action lasting five weeks to a more comprehensive four year package. The time between baseline and follow-up assessment varied from 6 to 24 months. No study reported measurement or intervention costs, and none incorporated the patient's voice in assessing PSC.

Practical implications: Assessing PSC in maternity units is feasible using validated questionnaires. Interventions to enhance PSC have not been rigorously evaluated. Future studies should report PSC measurement costs, adopt more rigorous evaluation designs and find ways to incorporate the patient's voice.

Originality/value: This review summarized studies examining PSC in a highly important area and highlighted main limitations that future studies should consider.
