Sagittal Balance in Adolescent Idiopathic Scoliosis Managed With Intraoperative Skull Femoral Traction.

STUDY DESIGN: This is a retrospective cohort, single-center quality improvement study. OBJECTIVES: To evaluate the effect of the intraoperative skull femoral traction (IOSFT) on sagittal balance in posterior spinal instrumentation (PSI) to manage scoliosis. SUMMARY OF BACKGROUND DATA: IOSFT has been used routinely as an adjunct technique for facilitating PSI to manage scoliosis in our institution since 2010. Previous studies have raised concerns regarding the negative effect of IOSFT on lumbar lordosis. MATERIALS AND METHODS: The medical records and radiographs of 113 patients with adolescent idiopathic scoliosis managed with single stage PSI were reviewed. Eighty-five patients were operated with IOSFT (traction group) and 28 patients were operated without traction (nontraction group). Patients who had double (anterior-posterior) approaches or nonidiopathic scoliosis were excluded. Sagittal balance and pelvic parameters at 2 years of postoperative follow-up were the primary outcome measures. Statistical analysis was done with R for statistical computing. Median values and interquartile range were compared between groups using Wilcoxon rank sum, Fischer exact, and Welch t tests. P-values of <0.05 were considered statistically significant. RESULTS: No significant differences were found comparing postoperative lumbar lordosis in the nontraction group (54 degrees) with the traction group (53 degrees) (P=0.4953). No significant differences were found in postoperative sagittal vertical axis medians comparing both groups, with 17 mm in the nontraction group and 18 mm in the traction group (P=0.3994). No significant differences were found in postoperative pelvic parameters. The median pelvic incidence was 52 degrees in the nontraction group and 50 degrees in the traction group (P=0.2711). CONCLUSIONS: According to our results, the use of IOSFT as an adjunct to facilitate PSI for managing adolescent idiopathic scoliosis had no measurable negative impact on sagittal balance in our IOSFT cohort.

Quality, Safety, and Value of Innovating Classic Operative Techniques in Scoliosis Surgery: Intraoperative Traction and Navigated Sequential Drilling.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: This study aims to measure and describe the clinical and financial implications of the systematic implementation of intraoperative skull-femoral traction (IOSFT) and navigated sequential drilling (NSD) for posterior spinal instrumentation and fusion (PSIF) in adolescent idiopathic scoliosis (AIS) at our institution. SUMMARY OF BACKGROUND DATA: PSIF has been the standard surgical treatment for AIS. This retrospective single-center quality improvement study describes the perioperative outcomes and impact on health resource utilization following the systematic application of two classic surgical strategies modified using current technology: IOSFT and NSD. METHODS: We reviewed the medical records of 125 patients who underwent a single-stage PSIF for AIS. We identified three cohorts based on surgical strategies used intraoperatively. Traditional techniques (n = 28), IOSFT (n = 45), and IOSFT plus NSD (n = 52). The primary outcome measures were operative time, prevalence of cases requiring extended operating room time, need for blood transfusion, length of hospital stay, and cost per surgery. Secondary outcomes included implant density, degree of spine deformity correction, and perioperative complications. RESULTS: All primary outcome measures improved significantly (p < .001). Median operating time decreased by 59%. Use of late operating room hours fell from 89% to 0% and transfusion rates from 64% to 1.9%. Length of hospital stay decreased from 6 to 4 days. Comprehensive cost per case decreased by 24%. DISCUSSION: Together, IOSFT and NSD improved the quality, safety, and value of care. These surgical strategies were performed without increased perioperative complications, while reducing cost per case by 24%. CONCLUSIONS: The data presented may have significant implications in health resource utilization for AIS surgery. LEVEL OF EVIDENCE: Level III.

An orientation to wellness for new faculty of medicine members: meeting a need in faculty development.

OBJECTIVES: To evaluate the format, content, and effectiveness of a newly developed orientation to wellness workshop, and to explore participants' overall perceptions. METHODS: This was a mixed methods study. Participants consisted of 47 new faculty of medicine members who attended one of the four workshops held between 2011 and 2013. Questionnaires were used to evaluate workshop characteristics (10 survey items; response scale 1=unacceptable to 7=outstanding), intention to change behavior (yes/no), and retrospective pre/post workshop self-efficacy (4 survey items; response scale 1=no confidence to 6=absolute confidence). Mean scores and standard deviations were calculated for the workshop characteristics. Pre/post workshop self-efficacy scores were compared using a Wilcoxon signed-rank test. Participants' written qualitative feedback was coded using an inductive strategy to identify themes. RESULTS: There was strong support for the workshop characteristics with mean scores entirely above 6.00 (N=42). Thirty-one of 34 respondents (91%) expressed intention to change their behavior as a result of participating in the workshop. The post workshop self-efficacy scores (N=38 respondents) increased significantly for all four items (p<0.0001) compared to pre workshop ratings. Participants perceived the key workshop elements as the evidence-based content relevant to academic physicians, incorporation of practical tips and strategies, and an atmosphere conducive to discussion and experience sharing. CONCLUSIONS:   Participants welcomed wellness as a focus of faculty development. Enhancing instruction around wellness has the potential to contribute positively to the professional competency and overall functioning of faculty of medicine members.

Lay media reporting of rosiglitazone risk: extent, messaging and quality of reporting.

BACKGROUND: A meta-analysis suggested the use of rosiglitazone was associated with an increased risk for cardiovascular (CV) events. Rosiglitazone remained available for use as more definitive safety trials were ongoing. This issue was reported in the lay media. OBJECTIVE: To review lay media articles to determine the extent of media coverage, the nature of the messaging, and to assess the quality of reporting. METHODS: The Factiva media database was used to identify articles published between May 18 and August 31, 2007. Two reviewers (a lay person and a physician) screened full text articles for eligibility, appraised the articles for their tone (worrisome, neutral, not worrisome), and for the quality of medical data reporting. RESULTS: The search identified 156 articles, 95 of which were eligible for our review. Agreement between the lay and medical reviewers in the appraisal of the article tone was 67.4%. Among those with agreement, the articles were often appraised as "worrisome" (75.3%). Among those with disagreement, the lay reviewer was significantly more likely to appraise articles as worrisome compared to the medical reviewer (77.4% vs. 3.2%, X2 = 9.11, P = 0.003). Cardiovascular risk was discussed in 91.6% of the articles, but risk was often reported in qualitative or relative terms. CONCLUSION: There were many lay media articles addressing the safety of rosiglitazone, and the general messaging of these articles was considered "worrisome" by reviewers. Quality of risk reporting in the articles reviewed was poor. The impact of such media coverage on public anxiety and confidence in treatment should be explored.
