Racial and ethnic disparities in utilization rate, hospital volume, and perioperative outcomes after total knee arthroplasty.
The researchers sought to study racial disparities in the utilization of total knee arthroplasty (TKA), the use of high-volume hospitals, and TKA outcomes, including mortality and complications, using all-payer databases. They found that minorities had lower rates of TKA utilization but higher rates of adverse health outcomes associated with the procedure, even after adjusting for patient-related and health-care system-related characteristics.

Number of diverticulitis episodes before resection and factors associated with earlier interventions.
The authors described patterns of episodes of diverticulitis before surgery and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims. They found that 56.3% of elective resections for uncomplicated diverticulitis occurred after fewer than 3 episodes. Further, they determined that earlier surgery was not explained by younger age, laparoscopy, time between the last 2 episodes preceding surgery, or financial risk-bearing for patients.

Does rural residence impact total ankle arthroplasty utilization and outcomes?
The objective of this study was to compare total ankle arthroplasty (TAA) utilization and outcomes by patient residence. It demonstrated an absence of any evidence of rural-urban differences in TAA outcomes. The rural-urban differences in TAA utilization noted in 2003 were no longer significant in 2011.

Long-term reduction of health care costs and utilization after epilepsy surgery.
This study assessed long-term direct medical costs, health care utilization, and mortality following resective surgery in persons with uncontrolled epilepsy. It found that the mean direct medical cost difference between the surgical group and control group was $6,806 after risk-set matching. The incidence rate ratio of inpatient, emergency room, and outpatient utilization was lower among the surgical group in both unadjusted and adjusted analyses.

Time trends in total ankle arthroplasty in the USA: a study of the National Inpatient Sample.
The objective of this study was to assess the time trends in utilization, clinical characteristics, and outcomes of patients undergoing total ankle arthroplasty (TAA) in the USA. It concluded that the utilization rate of TAA increased rapidly in the USA from 1998 to 2010, but post-arthroplasty mortality rate was stable. Underlying diagnosis and medical comorbidity changed over time and both can impact outcomes after TAA.
