300 October–December 2009 Identifying organizational cultures that promote patient safety Sara J. Singer Alyson Falwell David M. Gaba Mark Meterko Amy Rosen Christine W. Hartmann Laurence Baker Background: Safety climate refers to shared perceptions of what an organization is like with regard to safety, whereas safety culture refers to employees’ fundamental ideology and orientation and explains why safety is pursued in the manner exhibited within a particular organization. Although research has sought to identify opportunities for improving safety outcomes by studying patterns of variation in safety climate, few empirical studies have examined the impact of organizational characteristics such as culture on hospital safety climate. Purpose: This study explored how aspects of general organizational culture relate to hospital patient safety climate. Methodology: In a stratified sample of 92 U.S. hospitals, we sampled 100% of senior managers and physicians and 10% of other hospital workers. The Patient Safety Climate in Healthcare Organizations and the Zammuto and Krakower organizational culture surveys measured safety climate and group, entrepreneurial, hierarchical, and production orientation of hospitals’ culture, respectively. We administered safety climate surveys to 18,361 personnel and organizational culture surveys to a 5,894 random subsample between March 2004 and May 2005. Secondary data came from the 2004 American Hospital Association Annual Hospital Survey and Dun & Bradstreet. Hierarchical linear regressions assessed relationships between organizational culture and safety climate measures. Findings: Aspects of general organizational culture were strongly related to safety climate. A higher level of group culture correlated with a higher level of safety climate, but more hierarchical culture was associated with lower safety climate. Aspects of organizational culture accounted for more than threefold improvement in measures of model fit compared with models with controls alone. A mix of culture types, emphasizing group culture, seemed optimal for safety climate. Practice Implications: Safety climate and organizational culture are positively related. Results support strategies that promote group orientation and reduced hierarchy, including use of multidisciplinary team training, continuous quality improvement tools, and human resource practices and policies.

Organizational Cultures That Promote Patient Safety 301 ublication of startling statistics nearly a decade ago about the extent of preventable medical errors Figure 1 Phas directed attention to the ‘‘culture of safety’’ in Competing values framework, adapted health care organizations (Institute of Medicine, 2000). from Quinn 1984 Subsequent research has sought to identify opportunities for improving safety outcomes by studying patterns of variation in what has been termed ‘‘safety climate’’ (Flin, Burns, Mearns, Yule, & Robertson, 2006). Climate and culture are not synonymous, although they are often used interchangeably (Zohar, 1980). Climate has been ‘‘defined as a perceptually based description of what the organization is like in terms of practices, policies, procedures, and routines, while culture helps define the underlying reasons and mechanisms for why these things occur in an organization based on fundamental ideolo- gies, assumptions, values, and artifacts’’ (Ostroff, Kinicki, & Tamkins, 2003). Thus, climate refers to shared per- ceptions related to a given, specific area of interest, such as safety (Schneider & Bowen, 1993), whereas culture refers to employees’ fundamental ideology and orienta- tion (Trice & Beyer, 1993) and explains why an objec- tive like safety is pursued in the manner exhibited within a particular organization (Schein, 1992). and participation and distributes rewards equally among Limited research has examined organizational charac- members. An entrepreneurial culture is characterized by teristics that may affect safety climate in hospitals (Zohar innovation, by risk taking, by focus on growth, and by & Luria, 2004). In particular, we know little about how rewards for individual initiative. It should be noted that the organizational context could be modified to improve ‘‘risk taking’’ in this context does not imply taking risks safety climate.
