: The US health care system is struggling with rising costs, poor outcomes, waste, and inefficiency. The Patient Protection and Affordable Care Act represents a substantial effort to improve access and emphasizes value-based care. Value in health care has been defined as health outcomes for the patient per dollar spent. However, given the opacity of health outcomes and cost, the identification and quantification of patient-centered value is problematic. These problems are magnified by highly technical, specialized care (eg, neurosurgery). This is further complicated by potentially competing interests of the 5 major stakeholders in health care: patients, doctors, payers, hospitals, and manufacturers. These stakeholders are watching with great interest as health care in the United States moves toward a value-based system. Market principles can be harnessed to drive costs down, improve outcomes, and improve overall value to patients. However, there are many caveats to a market-based, value-driven system that must be identified and addressed. Many excellent neurosurgical efforts are already underway to nudge health care toward increased efficiency, decreased costs, and improved quality. Patient-centered shared value can provide a philosophical mooring for the development of health care policies that utilize market principles without losing sight of the ultimate goals of health care, to care for patients.

OBJECTIVE
To evaluate contemporary national trends and outcomes of open pyeloplasty (OP) vs minimally invasive pyeloplasty (MIP) in the treatment of ureteropelvic junction obstruction using the National Surgical Quality Improvement Program database.
METHODS
Patients treated by OP or MIP between 2006 and 2011 were identified by The International Classification of Diseases, Ninth Revision, Clinical Modification codes corresponding to pyeloplasty as their primary operative procedure. Perioperative variables were analyzed using the chi-square and the Student t test. Multiple logistic regressions were used to identify morbidities and readmission risk factors.
RESULTS
Three hundred fifty-five patients were identified. Of them, 20.2% of cases were OP and 79.8% were MIP. There was a significant increase in MIP from 33% in 2006 to 83% in 2011 (P <.001). A total of 11.7% of patients in the MIP group underwent outpatient surgery (P = .002). Patients treated at a teaching hospital were over 3 times more likely to undergo MIP (odds ratio = 3.17; P = .001). There was significantly longer hospitalization in OP vs MIP (3.9 vs. 2.2 days; P = .001). OP was associated with significantly increased risk of reoperation or postoperative morbidity compared with MIP (11.1% vs. 4.2%; P = .02). Multivariate analysis confirmed a higher rate of overall morbidity in the OP cohort (P = .03). Male patients had significantly higher postoperative morbidity or reoperation rates (odds ratio = 4.38; P = .002). There was no significant difference in operative time between groups (P = .2).
CONCLUSION
Within the American College of Surgeons National Surgical Quality Improvement Program hospitals, MIP is associated with decreased reoperation and postoperative morbidity compared with OP.

IMPORTANCE
There is a paucity of data assessing the effect of increased surgical duration on the incidence of venous thromboembolism (VTE).
OBJECTIVE
To examine the association between surgical duration and the incidence of VTE.
DESIGN, SETTINGS, AND PARTICIPANTS
Retrospective cohort of 1,432,855 patients undergoing surgery under general anesthesia at 315 US hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program from 2005 to 2011.
EXPOSURE
Duration of surgery.
MAIN OUTCOMES AND MEASURES
The rates of deep vein thrombosis (DVT), pulmonary embolism (PE), and VTE within 30 days of the index operation. Surgical duration was standardized across Current Procedural Terminology codes using a z score. Outcomes were compared across quintiles of the z score. Multiple logistic regression models were developed to examine the association while adjusting for patient demographics, clinical characteristics, and comorbidities.
RESULTS
The overall VTE rate was 0.96% (n = 13,809); the rates of DVT and PE were 0.71% (n = 10,198) and 0.33% (n = 4772), respectively. The association between surgical duration and VTE increased in a stepwise fashion. Compared with a procedure of average duration, patients undergoing the longest procedures experienced a 1.27-fold (95% CI, 1.21-1.34; adjusted risk difference [ARD], 0.23%) increase in the odds of developing a VTE; the shortest procedures demonstrated an odds ratio of 0.86 (95% CI, 0.83-0.88; ARD, -0.12%). The robustness of these results was substantiated with several sensitivity analyses attempting to minimize the effect of outliers, concurrent complications, procedural differences, and unmeasured confounding variables.
CONCLUSIONS AND RELEVANCE
Among patients undergoing surgery, an increase in surgical duration was directly associated with an increase in the risk for VTE. These findings may help inform preoperative and postoperative decision making related to surgery.
