Understanding the Value of Total Shoulder Arthroplasties at Physician-Owned Hospitals.

Background: Owing to concerns regarding higher cost, low quality of care and cherry-picking in physician-owned hospitals (POHs), the Affordable Care Act imposed sanctions that prevented the formation of new POHs. With an increasing utilization of total shoulder arthroplasties (TSAs), there is a need for re-evaluation and assessment of quality and cost of TSAs performed at these POHs.

Methods: The 2011 to 2014 Medicare 100% Standard Analytical Files was used to identify patients undergoing a reverse TSA or anatomic TSA at POHs and non-POHs.

High prevalence of outpatient falls following elective shoulder arthroplasty.

Background: This study characterized the prevalence and risk factors of inpatient and outpatient postoperative falls in patients undergoing elective shoulder arthroplasty.

Methods: A retrospective chart review of 198 patients undergoing anatomic or reverse total shoulder arthroplasty or hemiarthroplasties at one institution between 2015 and 2017 was reviewed to determine the prevalence of inpatient and outpatient falls up to 90 days after discharge. Univariate and multivariate analyses were conducted to assess potential risk factors for postoperative falls including demographics, indication for surgery, surgical procedure, medical history, length of hospital stay, perioperative hemoglobin, need for transfusion, and discharge disposition.

Analysis of stochastic fluctuations in responsiveness is a critical step toward personalized anesthesia.

Traditionally, drug dosing is based on a concentration-response relationship estimated in a population. Yet, in specific individuals, decisions based on the population-level effects frequently result in over or under-dosing. Here, we interrogate the relationship between population-based and individual-based responses to anesthetics in mice and zebrafish.
