Abstract

The clinical laboratory plays a crucial role in aiding physicians to diagnose disease. With numerous studies on “Speak Up” culture well-documented among providers and nurses surrounding patient safety, gaps in literature exist concerning “Speak Up” culture that address team effectiveness and organizational performance within the clinical lab setting. The purpose of this quantitative correlation study was to investigate the relationship between “Speak Up” culture level, team effectiveness, and organizational performance among health care workers employed in the clinical lab. The high-performance work practices model was utilized as the conceptual framework to ground this study. Research questions assessed the link between “Speak Up” culture level and team effectiveness as well as the connection between “Speak Up” culture level and organizational performance. Clinical lab employees (N = 233) completed a customized pulse survey administered and analyzed by a third-party survey vendor. The data were examined using descriptive and inferential statistics, which included performance of simple linear regression analysis (one-tail t test) to determine statistical significance. Results of the study demonstrated strong positive correlation among the variables; each unit increase in “Speak Up” culture level enhanced team effectiveness and organizational performance by a factor of .75 unit and .59 unit, respectively. This study contributes to positive social change by offering clinical lab leaders and health care administrators insights for promoting “Speak Up” culture within their organization to enhance team effectiveness and overall organizational performance that ultimately benefits consumers of health care.
