‘Speaking up’ about patient safety concerns and unprofessional behaviour among residents: validation of two scales

Developing a culture of safety is a core element of many efforts to improve patient safety and care quality. This systematic review identifies and assesses interventions used to promote safety culture or climate in acute care settings. The authors searched MEDLINE, CINAHL, PsycINFO, Cochrane, and EMBASE to identify relevant English-language studies published from January 2000 to October 2012. They selected studies that targeted health care workers practicing in inpatient settings and included data about change in patient safety culture or climate after a targeted intervention. Two raters independently screened 3679 abstracts (which yielded 33 eligible studies in 35 articles), extracted study data, and rated study quality and strength of evidence. Eight studies included executive walk rounds or interdisciplinary rounds; 8 evaluated multicomponent, unit-based interventions; and 20 included team training or communication initiatives. Twenty-nine studies reported some improvement in safety culture or patient outcomes, but measured outcomes were highly heterogeneous. Strength of evidence was low, and most studies were pre-post evaluations of low to moderate quality. Within these limits, evidence suggests that interventions can improve perceptions of safety culture and potentially reduce patient harm.

Five years ago the Institute of Medicine recommended improving patient safety by addressing organizational cultural issues. Since then, surveys measuring a patient safety climate considered predictive of health outcomes have begun to emerge. This paper compares the general characteristics, dimensions covered, psychometrics performed, and uses in studies of patient safety climate surveys. Systematic literature review. Nine surveys were found that measured the patient safety climate of an organization. All used Likert scales, mostly to measure attitudes of individuals. Nearly all covered five common dimensions of patient safety climate: leadership, policies and procedures, staffing, communication, and reporting. The strength of psychometric testing varied. While all had been used to compare units within or between hospitals, only one had explored the association between organizational climate and patient outcomes. Patient safety climate surveys vary considerably. Achievement of a culture conducive to patient safety may be an admirable goal in its own right, but more effort should be expended on understanding the relationship between measures of patient safety climate and patient outcomes.

To systematically review published quality improvement (QI) and patient safety (PS) curricula for medical students and/or residents to (1) determine educational content and teaching methods, (2) assess learning outcomes achieved, and (3) identify factors promoting or hindering curricular implementation. Data sources included Medline (to January 2009), EMBASE, HealthSTAR, and article bibliographies. Studies selected reported curricula outlining specific educational content and teaching format. For articles with an evaluative component, the authors abstracted methodological features, such as study design. For all articles, they conducted a thematic analysis to identify factors influencing successful implementation of the included curricula. Of 41 curricula that met the authors' criteria, 14 targeted medical students, 24 targeted residents, and 3 targeted both. Common educational content included continuous QI, root cause analysis, and systems thinking. Among 27 reports that included an evaluation, curricula were generally well accepted. Most curricula demonstrated improved knowledge. Thirteen studies (32%) successfully implemented local changes in care delivery, and seven (17%) significantly improved target processes of care. Factors that affected the successful curricular implementation included having sufficient numbers of faculty familiar with QI and PS content, addressing competing educational demands, and ensuring learners' buy-in and enthusiasm. Participants in some curricula also commented on discrepancies between curricular material and local institutional practice or culture. QI and PS curricula that target trainees usually improve learners' knowledge and frequently result in changes in clinical processes. However, successfully implementing such curricula requires attention to a number of learner, faculty, and organizational factors.
