Development and Evaluation of Patient Safety Interventions: Perspectives of Operational Safety Leaders and Patient Safety Organizations.

OBJECTIVES: The purpose of this study is to understand how patient safety professionals from healthcare facilities and patient safety organizations develop patient safety interventions and the resources used to support intervention development. METHODS: Semistructured interviews were conducted with patient safety professionals at nine healthcare facilities and nine patient safety organizations. Interview data were qualitatively analyzed, and findings were organized by the following: patient safety solutions and interventions, use of external databases, and evaluation of patient safety solutions. RESULTS: Development of patient safety interventions across healthcare facilities and patient safety organizations was similar and included literature searches, internal brainstorming, and interviews. Nearly all patient safety professionals at healthcare facilities reported contacting colleagues at other healthcare facilities to learn about similar safety issues and potential interventions. Additionally, less than half of patient safety professionals at healthcare facilities and patient safety organizations interviewed report data to publicly available patient safety databases. Finally, most patient safety professionals at healthcare facilities and patient safety organizations stated that they evaluate the effectiveness of patient safety interventions; however, they mentioned methods that may be less rigorous including audits, self-reporting, and subjective judgment. CONCLUSIONS: Patient safety professionals often utilize similar methods and resources to develop and evaluate patient safety interventions; however, many of these efforts are not coordinated across healthcare organizations and could benefit from working collectively in a systematic fashion. Additionally, healthcare facilities and patient safety organizations face similar challenges and there are several opportunities for optimization on a national level that may improve patient safety.

The Evaluation of Tactile Parameters and Display Prototype to Support Physiological Monitoring and Multitasking for Anesthesia Providers in the Operating Room.

Communicating physiological information via the tactile modality is shown as a promising means to address data overload faced by anesthesia providers. However, it is important to ensure that the tactile parameters which represent information are intuitive. There is currently no consensus on which tactile parameters should be used to present information within anesthesia. The two studies presented here evaluate: (a) a set of 24 tactile cues manipulating intensity, temporal, and spatial tactile parameters in a usability study and (b) a prototype tactile display based on the usability study's findings in a single and dual-task scenario. Findings of the usability study show intensity and temporal were rated most urgent and had the most potential to represent changes in physiological measures. This was confirmed in the follow up study as increases/decreases in intensity were shown to represent increases/decreases in a physiological measure and using different spatial locations to represent physiological measures resulted in greater than 95% response accuracy. Response times and accuracy were not adversely affected while performing a secondary task. The findings contribute to a better understanding of how to map tactile parameters to physiological information and demonstrate the effectiveness of end-user feedback in tactile display design to develop intuitive alerts.
