Reducing colorectal surgical site infections: a novel, resident-driven, quality initiative
2017
Surgical site infections (SSIs) cause significant patient morbidity and increase costs. This work prospectively examines our institutional effort to reduce SSIs through a resident-driven quality initiative.
A general surgery resident-championed, evidenced-based care bundle for patients undergoing colorectal surgery at a single academic institution was developed using attending mentorship. National Surgical Quality Improvement Program definitions for SSIs were used. Data were collected prospectively and bundle compliance was monitored using a checklist. The primary outcome compared SSIs before and after implementation.
In the 2 years preceding standardization, 489 colorectal surgery cases were performed. SSIs occurred in 68 patients (13.9% SSI rate). Following implementation of the bundle, 212 cases were performed with 10 SSIs (4.7% SSI rate, P < .01). Multivariate logistic regression analysis found a decrease in superficial and overall SSIs (odds ratio .17, 95% confidence interval .05 to .59; odds ratio .31, 95% confidence interval .14 to .68).
These data demonstrate that resident-driven initiatives to improve quality of care can be a swift and effective way to enact change. We observed significantly decreased SSIs with a renewed focus on evidence-based, standardized patient care.
•Question: We aim to show that a resident-driven and implemented quality initiative can measurably improve patient outcomes and care in an academic hospital center.•Findings: This was an implementation study that demonstrated a significant decrease in surgical site infections from 13.9% to 4.7% after initiating a colorectal surgery care bundle.•Meaning: Patient care initiatives can and should be initiated by all members of the health community and have the potential to measurably improve the care of patients.

Using data from the Nationwide Inpatient Sample, we investigated the impact of surgical approach and race on in-hospital mortality after lobectomy for lung cancer.
Logistic regression was used to model odds ratios for in-hospital mortality related to surgical technique (thoracotomy vs video assisted thoracoscopic surgery [VATS]) and race using discharge data from the Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality (2008 to 2011).
VATS lobectomies increased each year (25.9% to 39.2%, P = .001) in the 19,353 patients identified. A racial disparity was noted, with black patients being 66% more likely to die in the hospital (odds ratio 1.66, 95% confidence interval 1.17 to 2.37, P = .005). Excluding 2010 data suggests that there is evidence of benefit associated with VATS; however, no evidence of an association between race and in-hospital mortality exists.
This study elucidates race-related mortality in lobectomy patients. Although racial disparities are present throughout health care, this finding emphasizes one of the challenges in using large databases to assess such disparities.

Background
Treatment guidelines for stage I–III esophageal cancer indicate that management should include surgery in appropriate patients. Variations in utilization of surgery may contribute to racial differences observed in survival. We sought to identify factors associated with racial disparities in surgical resection of esophageal cancer and evaluate associated survival differences.
Methods
Patients diagnosed with stage I–III esophageal cancer from 2004 to 2015 were identified using the National Cancer Database. Matched patient cohorts were created to reduce confounding. Multivariate logistic regression was used to identify factors associated with receipt of surgery. Multi-level modeling was performed to control for random effects of individual hospitals on surgical utilization.
Results
A total of 60,041 patients were included (4402 black; 55,639 white). After 1:1 matching, there were 5858 patients evenly distributed across race. For all stages, significantly fewer black than white patients received surgery. Black race independently conferred lower likelihood of receiving surgery in single-level multivariable analysis (OR (95% CI); stage I, 0.67 (0.48–0.94); stage II, 0.76 (0.60–0.96); stage III, 0.62 (0.50–0.76)) and after controlling for hospital random effects. Hospital-level random effects accounted for one third of the unexplained variance in receipt of surgery. Risk-adjusted 1-, 3-, and 5-year mortality was higher for patients who did not undergo surgery.
Conclusion
Black patients with esophageal cancer are at higher risk of mortality compared to white patients. This increased risk may be influenced by decreased likelihood of receiving surgical intervention for resectable disease, in part because of between-hospital differences. Improving access to surgical care may improve disparities in esophageal cancer survival.

Deep vein thrombosis (DVT) is linked to reimbursements and publicly reported metrics. Some hospitals discourage venous duplex ultrasound (VDUS) screening in asymptomatic trauma patients because they often find higher rates of DVT. We aim to evaluate the association between lower extremity (LE) VDUS screening and pulmonary embolism (PE) in trauma patients. Trauma patients admitted to an urban Level-1 trauma center between 2010 and 2015 were retrospectively analyzed. We characterized the association of asymptomatic LE VDUSs with PE, upper extremity DVT, proximal LE DVT, and distal LE DVT by univariate and multivariable logistic regression controlling for confounders. Of the 3959 trauma patients included in our study—after adjusting for covariates related to patient demographics, injury, and procedures—there was a significantly lower likelihood of PE in screened patients (odds ratio (OR) = 0.02, P < 0.001) and a higher rate of distal LE DVT (OR 11.1, P = 0.004). Screening was not associated with higher rates of proximal LE DVTafter adjustment for covariates (OR = 1.8, P = 0.193). PE was associated with patient transfer status, pelvis fracture, and spinal procedures in unscreened patients. After adjusting for covariates, we have shown that LE VDUS asymptomatic screening is associated with lower rates of PE in trauma patients and not associated with higher rates of proximal LE DVT. Our detailed institutional review of a large cohort of trauma patients over five years provides support for ongoing asymptomatic screening and better characterizes venous thromboembolism outcomes than similarly sized purely administrative data reviews. As a retrospective cohort study with a large sample size, no loss to follow-up, and a population with low heterogeneity, this study should be considered as level III evidence for care management.

Disparity in age at lung cancer diagnosis between current and former smokers
2019
PurposeIn a previous study of smoking cessation in veterans with lung cancer, we noted as an incidental finding that current smokers were much younger than former smokers at diagnosis. To confirm and extend this observation, we analyzed the association of smoking status with age at diagnosis and survival of lung cancer patients.MethodsThe Jefferson Cancer Registry collects information on all cancer patients registered at this hospital. Information on smoking status has been recorded since 1995. We determined age at diagnosis and survival of current and former smokers with lung cancer.Results5111 lung cancer cases were identified in the registry from 1995 to 2011 inclusive. Smoking status was recorded in 4687 cases (91.7%). Of these, 1859 (39.7%) were current, 2423 (51.7%) were former, and 405 (8.6%) were never smokers. There was a 6-year difference in median age at lung cancer diagnosis between the current (63 years) and former smokers (69 years) (P < 0.0001). The median survival was 12.1 months for current versus 14.5 months for former smokers (P < 0.0001).ConclusionsThese results confirm and extend our observation that among patients diagnosed with lung cancer, current smokers are younger than former smokers. The possible explanations include higher competing causes of death and increased risk of lung cancer among current smokers as well as increasing proportions of former smokers in older populations. Ongoing exposure to tobacco carcinogens may accelerate the development of lung cancer in continuing smokers. This provides more incentive for smokers to quit at the earliest age possible.
