Implementation of an Enhanced Recovery After Spine Surgery program at a large cancer center: a preliminary analysis.

This study describes the implementation of a multimodal, multidisciplinary, evidence-based ERAS program in oncologic spine surgery, identifies and measures several relevant postoperative recovery outcomes, and demonstrates the feasibility and potential benefit of the program in improving analgesia and decreasing opioid consumption. The study underscores the importance of defining and capturing meaningful, patient-specific, and patient-reported outcomes, and constant evaluation and monitoring of a group's compliance with the program. The study represents the steppingstone for evaluation and improvement of a young ERAS program for spine surgery and serves as a roadmap for further initiatives and larger-scale studies.

Near-peers improve patient safety training in the preclinical curriculum.

BACKGROUND: Accrediting bodies require medical schools to teach patient safety and residents to develop teaching skills in patient safety. We created a patient safety course in the preclinical curriculum and used continuous quality improvement to make changes over time. OBJECTIVE: To assess the impact of resident teaching on student perceptions of a Patient Safety course. DESIGN: Using the Institute for Healthcare Improvement patient safety curriculum as a frame, the course included the seven IHI modules, large group lectures and small group facilitated discussions. Applying a social action methodology, we evaluated the course for four years (Y1-Y4). RESULTS: In Y1, Y2, Y3 and Y4, we distributed a course evaluation to each student (n = 184, 189, 191, and 184, respectively) and the response rate was 96, 97, 95 and 100%, respectively. Overall course quality, clarity of course goals and value of small group discussions increased in Y2 after the introduction of residents as small group facilitators. The value of residents and the overall value of the course increased in Y3 after we provided residents with small group facilitation training. CONCLUSIONS: Preclinical students value the interaction with residents and may perceive the overall value of a course to be improved based on near-peer involvement. Residents gain valuable experience in small group facilitation and leadership.

Intraoperative hypotensive resuscitation for patients undergoing laparotomy or thoracotomy for trauma: Early termination of a randomized prospective clinical trial.

BACKGROUND: Hemorrhagic shock is responsible for one third of trauma related deaths. We hypothesized that intraoperative hypotensive resuscitation would improve survival for patients undergoing operative control of hemorrhage following penetrating trauma. METHODS: Between July 1, 2007, and March 28, 2013, penetrating trauma patients aged 14 years to 45 years with a systolic blood pressure of 90 mm Hg or lower requiring laparotomy or thoracotomy for control of hemorrhage were randomized 1:1 based on a target minimum mean arterial pressure (MAP) of 50 mm Hg (experimental arm, LMAP) or 65 mm Hg (control arm, HMAP). Patients were followed up 30 days postoperatively. The primary outcome of mortality; secondary outcomes including stroke, myocardial infarction, renal failure, coagulopathy, and infection; and other clinical data were analyzed between study arms using univariate and Kaplan-Meier analyses. RESULTS: The trial enrolled 168 patients (86 LMAP, 82 HMAP patients) before early termination, in part because of clinical equipoise and futility. Injuries resulted from gunshot wounds (76%) and stab wounds (24%); 90% of the patients were male, and the median age was 31 years. Baseline vitals, laboratory results, and injury severity were similar between groups. Intraoperative MAP was 65.5 ± 11.6 mm Hg in the LMAP group and 69.1 ± 13.8 mm Hg in the HMAP group (p = 0.07). No significant survival advantage existed for the LMAP group at 30 days (p = 0.48) or 24 hours (p = 0.27). Secondary outcomes were similar for the LMAP and HMAP groups: acute myocardial infarction (1% vs. 2%), stroke (0% vs. 3%), any renal failure (15% vs. 12%), coagulopathy (28% vs. 29%), and infection (59% vs. 58%) (p > 0.05 for all). Acute renal injury occurred less often in the LMAP than in HMAP group (13% vs. 30%, p = 0.01). CONCLUSION: This study was unable to demonstrate that hypotensive resuscitation at a target MAP of 50 mm Hg could significantly improve 30-day mortality. Further study is necessary to fully realize the benefits of hypotensive resuscitation. LEVEL OF EVIDENCE: Therapeutic study, level II.

The emerging use of ketamine for anesthesia and sedation in traumatic brain injuries.

Traditionally, the use of ketamine for patients with traumatic brain injuries is contraindicated due to the concern of increasing intracranial pressure (ICP). These concerns, however, originated from early studies and case reports that were inadequately controlled and designed. Recently, the concern of using ketamine in these patients has been challenged by a number of published studies demonstrating that the use of ketamine was safe in these patients. This article reviews the current literature in regards to using ketamine in patients with traumatic brain injuries in different clinical settings associated with anesthesia, as well as reviews the potential mechanisms underlying the neuroprotective effects of ketamine. Studies examining the use of ketamine for induction, maintenance, and sedation in patients with TBI have had promising results. The use of ketamine in a controlled ventilation setting and in combination with other sedative agents has demonstrated no increase in ICP. The role of ketamine as a neuroprotective agent in humans remains inconclusive and adequately powered; randomized controlled trials performed in patients undergoing surgery for traumatic brain injury are necessary.

Performance outcomes in anesthesiology residents completing categorical (anesthesia) or advanced (nonspecific) internship training.

BACKGROUND: The internship or first year (PGY 1) of anesthesiology training may be categorical (within anesthesiology), or obtained in more diverse settings. Revisions recently proposed in the training requirements incorporated the PGY 1 into the existing curriculum. PURPOSES: We studied whether this change improved measurable outcomes. METHODS: There were 518 residents studied retrospectively from four institutions that offered entry following both "Categorical" and "Other" internships. Thus the training in clinical anesthesia was identical. RESULTS: No differences were observed in percentile scores on the Anesthesiology In-Service Training Examination during clinical anesthesia training, the receipt of awards, board certification or time to certification, or in reports of unsatisfactory performance to the American Board of Anesthesiology. "Categorical" residents were more frequently appointed chief resident. CONCLUSIONS: Easily accessible performance measures may function as valuable aids in decision making, particularly when significant changes in curricula are contemplated. Data do not support the proposed changes in anesthesiology.
