Process Improvement in Thoracic Donor Organ Procurement: Implementation of a Donor Assessment Checklist.

BACKGROUND: Donor organs are often procured by junior staff in stressful, unfamiliar environments where a single adverse event can be catastrophic. A formalized checklist focused on preprocedural processes related to thoracic donor organ procurement could improve detection and prevention of near miss events. METHODS: A checklist was developed centered on patient identifiers, organ compatibility and quality, and team readiness. It went through five cycles of feedback and revision using a panel of expert procurement surgeons. Educational in-service sessions were held on the use of the checklist as well as best organ assessment practices. Near miss events before the survey were tallied by retrospective review of 20 procurements, and near misses after checklist implementation were prospectively recorded. We implemented the checklist for 40 donor lung and heart procurements: 20 from Cleveland Clinic and 20 from the University of Minnesota. A final survey assessment was used to determine ease of use. RESULTS: Nine near miss events were reported in 20 procurements before use of the checklist. Thirty-one near miss events of 40 organ procurements were identified and potentially prevented by the checklist. Eighty-seven percent of fellows found the checklist to be unobtrusive to work flow, and 100% believed its use should be mandatory. Mortality was the same before and after implementation of the checklist despite increased patient volumes. CONCLUSIONS: Implementation of a simple checklist for use during thoracic organ procurement uncovered a substantial number of near miss events. A preprocedural checklist for all thoracic organ transplants in the United States and abroad is feasible and would likely reduce adverse events.

Association between postoperative acute kidney injury and duration of cardiopulmonary bypass: a meta-analysis.

OBJECTIVE: This meta-analysis examined the association between cardiopulmonary bypass (CPB) time and acute kidney injury (AKI). DESIGN: Meta-analysis of previously published studies. SETTING: Each single-center study was conducted in a surgical intensive care unit and/or academic or university hospital. PARTICIPANTS: Adult patients undergoing heart surgery with CPB. INTERVENTIONS: A systematic literature review was conducted using PubMed, EMBASE, and Cochrane Library databases and Google Scholar from January 1980 through September 2009. Initial search results were refined to include human subjects, age >18 years, randomized controlled trials, and prospective and retrospective cohort studies, meet the Acute Kidney Injury Network definition of renal failure, and report times on CPB. MEASUREMENTS AND MAIN RESULTS: The length of time on CPB has been implicated as an independent risk factor for development of AKI after CPB (AKI-CPB). The 9 independent studies included in the final meta-analysis had 12,466 patients who underwent CPB. Out of these, 756 patients (6.06%) developed AKI-CPB. In 7 of the 9 studies, the mean CPB times were statistically longer in the AKI-CPB cohort compared with the control group (cohort without AKI). The absolute mean differences in CPB time between the 2 groups were 25.65 minutes with the fixed-effects model and 23.18 minutes with the random-effects model. CONCLUSIONS: Longer CPB times are associated with a higher risk of developing AKI-CPB, which, in turn, has a significant effect on overall mortality as reported by the individual studies.
