RESUMO
Introduction: Transitioning from one clinical rotation to the next may be particularly stressful for orthopaedic residents attempting to navigate new work environments with new faculty mentors and new patients. The purpose of this quality improvement (QI) project was to determine if resident stress could be improved by using a handbook to disseminate key rotation-specific data during quarterly rotation transition periods. Methods: A comprehensive electronic handbook was created by residents to describe each rotation in our orthopaedic training program in terms of: (1) faculty and staff contact data, (2) daily clinic and surgery schedules, (3) resident responsibilities and faculty expectations, and (4) key resources and documents. At rotation transition, a session in the academic schedule was dedicated for outgoing residents to update the handbook and to sign-out to incoming residents. Pre- and post-handbook questionnaires were administered to assess resident perceptions of stress or anxiety, preparedness, and confidence before commencing the new rotation. Nonparametric data derived from the surveys were analyzed using the sign test choosing p < 0.05 for a two-tailed test as the level of statistical significance. Results: Most residents perceived improvements in stress/anxiety, preparedness, and confidence understanding rotation expectations after the handbook was implemented. Changes in these three outcome parameters were statistically significant. Conclusions: This rotation transition QI initiative consisting of a resident-authored, rotation-specific electronic handbook and dedicated verbal sign-out session enhanced resident wellness by decreasing stress, increasing preparedness, and improving confidence among residents starting a new rotation. Similar online resources may be useful for trainees in other specialties.
RESUMO
Introduction: Although the use of antifibrinolytics to reduce perioperative blood loss during total knee arthroplasty (TKA) has shown unequivocal benefit in regard to blood conservation, the best route of administration remains in question. This study tested the hypothesis that topical delivery of epsilon-aminocaproic acid (EACA) was superior to intravenous (IV) administration in the setting of primary TKA. Methods: This cross-sectional study included a six-year retrospective chart review of TKA patients done by a single surgeon. Post-operative hemoglobin levels and the incidence of blood transfusions were compared among three patient subgroups: no EACA, topical EACA, or IV EACA. Key outcome measures included post-operative hemoglobin, need for post-operative transfusion, and length of hospital stay. Results: Of the 668 patients included in this study, 351 (52.5%) received IV EACA, 298 (44.6%) received topical EACA, and 19 (2.8%) received no EACA. For the three-way comparisons, significant differences were observed for post-operative mean hemoglobin on day one (p < 0.001), day two (p < 0.001), and day three (p = 0.004), with consistently higher means for participants in the topical group. Eight patients required transfusions in the IV EACA group, but none were needed in the topical EACA group (p = 0.027). Length of stay was shortest for patients in the topical group, with 66% hospitalized for two days, while 84% of the IV group remained hospitalized for three days (p < 0.001). Conclusions: The topical delivery of EACA is superior to IV administration with respect to blood conservation for patients undergoing primary TKA.
