“…Health maintenance organization penetration was defined as the proportion of enrollees within each market who were enrolled in a Medicare-managed care plan (ie, Medicare Advantage), as used in previous studies. 12 Market-level competition was determined using the Herfindahl-Hirschman Index (HHI), which is calculated as the sum of the squared market share of each hospital within each HRR and has been widely used to evaluate competition within markets. 13 A high HHI represents high concentration (ie, low competition) within an HRR, and a low HHI represents low concentration (ie, high competition).…”

Background: Percutaneous ventricular assist devices (PVADs) have been replacing intra-aortic balloon pumps for hemodynamic support during percutaneous coronary intervention (PCI), even though data supporting a benefit for hard clinical end points remain limited. We evaluated diffusion of PVADs across US markets and examined the association of market utilization of PVAD with mortality and cost. Methods: Using the 2013 to 2019 Medicare data, we identified all patients aged ≥65 years who underwent PCI with either a PVAD or intra-aortic balloon pump. We used hospital referral region to define regional health care markets and categorized them in quartiles based on the proportional use of PVADs during PCI. Multilevel models were constructed to determine the association of patient, hospital, and market factors with utilization of PVADs and the association of PVAD utilization with 30-day mortality and cost. Results: A total of 79 176 patients underwent PCI with either intra-aortic balloon pump (47 514 [60.0%]) or PVAD (31 662 [40.0%]). The proportion of PCI procedures with PVAD increased over time (17% in 2013 to 57% in 2019; P for trend, <0.001), such that PVADs overtook intra-aortic balloon pump for hemodynamic support during PCI in 2018. There was a large variation in PVAD utilization across markets (range, 0%–85%), which remained unchanged after adjustment of patient characteristics (median odds ratio, 2.05 [95% CI, 1.91–2.17]). The presence of acute myocardial infarction, cardiogenic shock, and emergent status was associated with a 45% to 50% lower odds of PVAD use suggesting that PVADs were less likely to be used in the sickest patients. Greater utilization of PVAD at the market level was not associated with lower risk mortality but was associated with higher cost. Conclusions: Although utilization of PVADs for PCI continues to increase, there is large variation in PVAD utilization across markets. Greater market utilization of PVADs was not associated with lower mortality but was associated with higher cost.

What Promotes Surgeon Practice Change? A Scoping Review of Innovation Adoption in Surgical Practice

et al. 2020

Objective: The goal of this scoping review was to summarize the literature on facilitators and barriers to surgical practice change. This information can inform research to implement best practices and evaluate new surgical innovations. Background: In an era of accelerated innovations, surgeons face the difficult decision to either acknowledge and implement or forgo new advances. Although changing surgical practice to align with evidence is an imperative of health systems, evidence-based guidelines have not translated into consistent change. The literature on practice change is limited and has largely focused on synthesizing information on methods and trials to evaluate innovative surgical interventions. No reviews to date have grounded their analysis within an implementation science framework. Methods: A systematic review of the literature on surgical practice change was performed. Abstracts and full-text articles were reviewed for relevance using inclusion and exclusion criteria and data were extracted from each article. Cited facilitators and barriers were then mapped across domains within the implementation science Theoretical Domains Framework and expanded to the Capability, Opportunity, Motivation, and Behavior model. Results: Components of the Capability, Opportunity, Motivation, and Behavior model were represented across the Theoretical Domains Framework domains and acted as both facilitators and barriers to practice change depending on the circumstances. Domains that most affected surgical practice change, in order, were: opportunity (environmental context and resources and social influences), capability (knowledge and skills), and motivation (beliefs about consequences and reinforcement). Conclusions: Practice change is predicated on a conducive environment with adequate resources, but once that is established, the surgeon's individual characteristics, including skills, motivation, and reinforcement determine the likelihood of successful change. Deficiencies in the literature underscore the need for further study of resource interventions and the role of surgical team dynamics in the adoption of innovation. A better understanding of these areas is needed to optimize our ability to disseminate and implement best practices in surgery.
