Adductor canal block versus femoral nerve block for total knee arthroplasty: a prospective, randomized, controlled trial.
In a study of pain relief for patients recovering from a total knee arthroplasty, researchers found that adductor canal block (ACB) results in less motor impairment for quadriceps muscles after surgery than femoral nerve block (FNB) and it provides a comparable level of pain relief. The prospective, randomized, controlled study included 46 patients receiving ACB and 47 receiving FNB.

Surgical site infections following ambulatory surgery procedures.
The authors determined the incidence of clinically significant surgical site infections (CS-SSIs) following low- to moderate-risk ambulatory surgery in patients with low risk for surgical complications. They found that among patients in 8 states undergoing ambulatory surgery, rates of postsurgical visits for CS-SSIs were low relative to all causes but may represent a substantial number of adverse outcomes in aggregate, thus meriting quality improvement efforts to minimize their occurrence.

Factors associated with adoption of robotic surgical technology in US hospitals and relationship to radical prostatectomy procedure volume.
The authors aimed to identify the factors associated with hospitals' decisions to adopt robotic technology and the consequences of these decisions. They found that hospitals in areas where a higher proportion of other hospitals had already acquired a robot were more likely to acquire one, as were those with more than 300 beds and teaching hospitals. They also found a significant association between years with a robot and the change in the number of radical prostatectomies. They concluded that local area robot competition was associated with the rapid spread of robot technology in the United States.

Harnessing claims to improve detection of surgical site infections following hysterectomy and colorectal surgery.
The researchers conducted retrospective cohort studies at 2 academic medical centers, extending analyses of patients undergoing hysterectomy or colorectal surgery. They concluded that claims-enhanced surveillance can help to identify surgical site infections (SSIs) missed by routine surveillance, identifying nearly twice as many SSIs following hysterectomy and 4 times more SSIs following colorectal surgery.

Routine prophylactic central neck dissection for low-risk papillary thyroid cancer: a cost-effectiveness analysis.
The researchers hypothesized that routine prophylactic central neck dissection (pCND) is not cost-effective in low-risk papillary thyroid cancer (PTC).Using a Markov transition-state model, they found that pCND cost $10,315 and produced an effectiveness of 23.785 quality-adjusted life years. They concluded that routine pCND for low-risk PTC is not cost-effective unless the recurrence rate is greater than 10.3 percent.

Surgeons' perceptions of public reporting of hospital and individual surgeon quality.
This study (1) evaluated surgeons’ perceptions of public reporting of surgical quality; and (2) identified specific barriers to surgeons’ acceptance of public reporting. It found that surgeons are generally in favor of public reporting, but that they continue to have substantive concerns, particularly with respect to reporting individual level outcomes data.

The influence of hamstring autograft size on patient-reported outcomes and risk of revision after anterior cruciate ligament reconstruction: a Multicenter Orthopaedic Outcomes Network (MOON) Cohort Study.
The purpose of this study was to evaluate the effect of graft size on patient-reported outcomes and revision risk after anterior cruciate ligament (ACL) reconstruction. It found that smaller hamstring autograft size is a predictor of poorer Knee Injury and Osteoarthritis Outcome Score (sport/recreation subscale function) 2 years after primary ACL reconstruction.

Chronic use of opioid medications before and after bariatric surgery.
This study of 11,179 obese patients receiving bariatric surgery found that among the 933 who were using opioids chronically before bariatric surgery, 77 percent continued chronic opioid use in the year following surgery (excluding the first 30 days after surgery). The amount of chronic opioid use was greater postoperatively than preoperatively.

Effectiveness of mesh compared with nonmesh sling surgery in Medicare beneficiaries.
This study assessed the effectiveness of mesh compared to nonmesh slings in the surgical treatment of female incontinence. It found that overall rates of complications were similar for patients undergoing either mesh or nonmesh sling procedures. However, patients undergoing the nonmesh procedure were more likely to require a subsequent intervention for bladder outlet obstruction.

Long-term results of a randomized controlled trial of a nonoperative strategy (watchful waiting) for men with minimally symptomatic inguinal hernias.
This study of 254 men with minimally symptomatic inguinal hernia who were assigned to watchful waiting (WW) found that WW is a reasonable and safe strategy. However, the study which followed these patients for up to 11.5 years found that symptoms usually progressed and an operation was eventually needed, with 79 percent of men older than 65 and 62 percent of younger men receiving surgical repair.

Long-term outcomes of vaginal mesh versus native tissue repair for anterior vaginal wall prolapse.
This study estimated the rate of repeat surgery after vaginal mesh versus native tissue repair for anterior vaginal wall prolapse. The researchers found that the overall risk of any future surgery was higher in the women receiving mesh; however, native tissue and vaginal mesh surgery had similar 5-year risks for recurrent prolapse.

Black patients more likely than whites to undergo surgery at low-quality hospitals in segregated regions.
The authors assessed the extent to which living in racially segregated areas and living in geographic proximity to low-quality hospitals contribute to the disparity of black patients undergoing surgery at lower-quality hospitals more frequently than whites. Using Medicare data, they found that black patients tended to live closer to higher-quality hospitals than white patients but were more likely to receive surgery at low-quality hospitals. To address these disparities, care navigators and public reporting of comparative quality could steer patients and their referring physicians to higher-quality hospitals, while quality improvement efforts could focus on improving outcomes for high-risk surgery at hospitals that disproportionately serve black patients.

The value of linking hospital discharge and mortality data for comparative effectiveness research.
The purpose of this paper was to demonstrate the value of linking state community hospital discharge data to vital statistics death files for research by conducting a comparative effectiveness analysis. The analysis revealed that in the matched cohort, in-hospital and 30-day postdischarge mortality rates were significantly lower following endovascular aneurysm repair than open aneurysm repair, but differences in the 1- and 5-year rates were not statistically significant.
