Reducing and Sustaining Duplicate Medical Record Creation by Usability Testing and System Redesign.

OBJECTIVES: Duplicate medical record creation is a common and consequential health care systems error often caused by poor search system usability and inappropriate user training. METHODS: We conducted two phases of scenario-based usability testing with patient registrars working in areas at risk of generating duplicate medical records. Phase 1 evaluated the existing search system, which led to system redesigns. Phase 2 tested the redesigned system to mitigate potential errors before health system-wide implementation. To evaluate system effectiveness, we compared the monthly potential duplicate medical record rates for preimplementation and postimplementation months. RESULTS: The existing system could not effectively handle a misspelling, which led to failed search and duplicate medical record creation. Using the existing system, 96% of registrars found commonly spelled patient names whereas only 69% successfully found complicated names. Registrars lacked knowledge and usage of a phonetic matching function to assist in misspelling. The new system consistently captured the correct patient regardless of misspelling, but search returned more potential matches, resulting in, on average, 4 seconds longer to select common names. Potential monthly duplicate medical record rate reduced by 38%, from 4% to 2.3% after implementation of the new system, and has sustained at an average of 2.5% for 2 years. CONCLUSIONS: Usability testing was an effective method to reveal problems and aid system redesign to deliver a more user friendly system, hence reducing the potential for medical record duplication. Greater standards for usability would ensure that these improvements can be realized before rather than after exposing patients to risks.

Contributions of tele-intensive care unit (Tele-ICU) technology to quality of care and patient safety.

The deployment of remote monitoring of intensive care unit (ICU) patients, known as tele-ICU technology, promotes the efficient use of critical care resources. Although tele-ICU use has spread rapidly, the benefits vary widely among studies, and little is known about the specific characteristics of tele-ICU that provide benefits to patient care. The purpose of this study was to identify aspects of tele-ICU that contribute, whether positively or negatively, to care processes and patient outcomes. This study was not aimed at evaluating the impact of tele-ICU on care outcomes. We conducted a qualitative study using semistructured interviews. Sixty-one tele-ICU staff from 5 tele-ICUs participated in the study. We performed inductive content analysis and coded 722 pieces of text into 19 positive and 9 negative/neutral tele-ICU contributions to care processes and patient outcomes. We found that availability of extra resources can reduce on mortality and length of stay, that a tele-ICU could serve as a quality trigger to improve evidence-based medicine compliance, that tele-ICU can support medication management and improve medication safety, and that tele-ICU software alerts and monitoring by camera can help reduce the risk of patient falls and extubations. We also found that tele-ICU physicians can make poor care decisions leading to medication errors if they lack patient-related information. Moreover, the tele-ICU has no impact on patient care processes and outcomes when the technology is not accepted and used by ICU staff.

Motivation and job satisfaction of Tele-ICU nurses.

INTRODUCTION: Although the first tele-ICU has been in existence for more than 12 years, little is known about the work of tele-ICU nurses. This study examines sources of motivation and satisfaction of tele-ICU nurses. METHODS: A total of 50 nurses in 5 tele-ICUs were interviewed about reasons for working as a tele-ICU nurse and sources of satisfaction and dissatisfaction in their job. RESULTS: Nurses have different motivations to work in the tele-ICU, including the challenges and opportunities for new learning that occur while interacting with clinicians in the tele-ICU and the various ICUs being monitored. Tele-ICU nurses also appreciate the opportunities for teamwork with tele-ICU physicians and nurses. The relationship and interactions with the ICUs is sometimes mentioned as a dissatisfier. Some nurses miss being physically at the bedside, as well as interacting with patients and families. CONCLUSION: Most tele-ICU nurses are satisfied with their job. They like the challenge in their work and the opportunity to learn. For some nurses, the transition from a bedside caregiver to an information manager can be difficult. Other nurses have found a balance by working part-time in the tele-ICU and part-time in the ICU.

Computer decision support tools in primary care.

Computer Decision Support Tools (CDSTs) can support clinicians at various stages of the care process and improve healthcare, but implementation of these tools has been difficult. In this study we examine the need for, the use of, and barriers and facilitators to the use of a CDST from a human factor perspective. Results show that there is a need for CDSTs, and that physicians do use well-developed CDSTs. However, there are also barriers against the use, such usability issues and problems fitting them into the clinical workflow.

MEASURING WORKLOAD OF ICU NURSES WITH A QUESTIONNAIRE SURVEY: THE NASA TASK LOAD INDEX (TLX).

High workload of nurses in Intensive Care Units (ICUs) has been identified as a major patient safety and worker stress problem. However, relative little attention has been dedicated to the measurement of workload in healthcare. The objectives of this study are to describe and examine several methods to measure workload of ICU nurses. We then focus on the measurement of ICU nurses' workload using a subjective rating instrument: the NASA TLX.We conducted secondary data analysis on data from two, multi-side, cross-sectional questionnaire studies to examine several instruments to measure ICU nurses' workload. The combined database contains the data from 757 ICU nurses in 8 hospitals and 21 ICUs.Results show that the different methods to measure workload of ICU nurses, such as patient-based and operator-based workload, are only moderately correlated, or not correlated at all. Results show further that among the operator-based instruments, the NASA TLX is the most reliable and valid questionnaire to measure workload and that NASA TLX can be used in a healthcare setting. Managers of hospitals and ICUs can benefit from the results of this research as it provides benchmark data on workload experienced by nurses in a variety of ICUs.
