Insurance expansion and the utilization of inpatient surgery: evidence for a "Woodwork" effect?
The researchers examined rates of elective surgery in previously insured individuals before and after Massachusetts health care reform. They observed no increase in the overall rate of selected discretionary inpatient surgeries in Massachusetts versus control states for the entire population , as well as among the white and low-income subgroups.

Return to acute care following ambulatory surgery.
This study determined the rates of all-cause, unplanned revisits (i.e., not for routine medical care) within 30 days of ambulatory surgery and whether revisits were related to the operation. It found that acute care revisits following ambulatory operations in low-risk patients occurred with notable frequency across 6 diverse types of operations.

Age-related differences in the use of total shoulder arthroplasty over time: use and outcomes.
The authors assessed the age-related differences in the use of total shoulder arthroplasty (TSA) and outcomes, and associated time-trends using the United States Nationwide Inpatient Sample (NIS) between 1998 and 2010. They noted a time-related increase in the use of TSA and increasing age-related differences in outcomes indicating a changing epidemiology of the use of TSA and concluded that age-related differences in outcomes suggest that attention should focus on groups with the worst outcomes.

Prevalence of total hip and knee replacement in the United States.
The study’s objective was to estimate the prevalence of total hip and total knee replacement in the United States. It found that the 2010 prevalence of total hip and total knee replacement in the total U.S. population was 0.83 percent and 1.52 percent, respectively. Prevalence was higher among women than among men and increased with age.

Complications and resource use associated with surgery for Chiari Malformation type 1 in adults: a population perspective.
This study examined the complications and resource use associated with adult CM-1 surgery using administrative data. It concluded that complications after CM-1 surgery are common, and surgical complications are more frequent than medical complications. Also, certain comorbidities and demographic characteristics are associated with increased risk for complications.

Procedure-specific surgical site infection incidence varies widely within certain National Healthcare Safety Network surgery groups.
The objective of this study was to determine surgical site infection (SSI) incidence for clinically defined subgroups within 5 heterogeneous National Healthcare Safety Network surgery categories (amputation; bile duct, liver or pancreas; breast; colon; and hernia) in community hospitals in California, Florida, and New York. The 90-day SSI rates varied significantly within each of the 5 subgroups.

Thirty-day postoperative mortality among individuals with HIV infection receiving antiretroviral therapy and procedure-matched, uninfected comparators.
The researchers explored the current relationship between perioperative mortality and indicators of immune function, anemia, and hypoalbuminemia among HIV-infected and uninfected individuals. Among HIV-infected patients receiving antiretroviral therapy, modern postoperative mortality rates are low and lower CD4 cell counts are associated with increased mortality, but characteristics other than HIV status, such as age and hypoalbuminemia, are also important determinants of outcome.

Use of bone morphogenetic protein among patients undergoing fusion for degenerative diagnoses in the United States, 2002 to 2012.
The authors examined whether published concerns about the safety of bone morphogenetic protein (BMP) altered clinical practice. They found that use of BMP in spinal fusion surgery declined subsequent to published safety concerns and revelations of financial conflicts of interest for investigators involved in the pivotal clinical trials.

Variation in hospital inpatient prices across small geographic areas.
The authors examined whether market competition may influence the difference in the inpatient price per discharge between public and private payers across small geographic areas. They found greater geographic variation in the inpatient price per discharge among private than public payers for most hospital services, while hospitals in more concentrated markets were associated with a higher price per discharge among knee arthroplasty discharges for both payers. They concluded that hospitals charged significantly higher prices to private than public payers.

Effect of insurance expansion on utilization of inpatient surgery.
The researchers examined the differential effect of the Massachusetts insurance expansion on the use of discretionary vs. nondiscretionary surgical procedures. They found that discretionary surgery increased 9.3 percent while nondiscretionary surgery decreased by 4.5 percent. The greatest increase in discretionary surgery was observed for nonwhite participants.

Risk factors for early revision after total hip arthroplasty.
In order to obtain a better understanding of the risk factors for early revision total hip arthroplasty (THA), the researchers used statewide databases to identify a total of 207,256 patients who underwent primary THA. They found a number of identifiable factors, including younger age, Medicaid, and low hospital volume increase the risk of undergoing early revision THA.

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.
