Hospital-based health systems 20 years later: a taxonomy for policy research and analysis.
Building on the original taxonomy of hospital-based health systems from 20 years ago, the investigators developed a new taxonomy to inform emerging public policy and practice developments. The study design included a cluster analysis of the 2016 AHA Annual Survey data to derive measures of differentiation, centralization, and integration to create categories or types of hospital-based health systems.

Comparing methods of grouping hospitals.
The purpose of this study was to compare the performance of widely used approaches for defining groups of hospitals and a new approach based on network analysis of shared patient volume. Results showed that community detection algorithm-defined hospital groups offer high validity, reliability to different specifications, and generalizability to many uses when compared to approaches in widespread use today. They may offer a better choice for efforts seeking to analyze the behaviors and dynamics of groups of hospitals. Measures of modularity, shared information, inclusivity, and shared behavior can be used to evaluate different approaches to grouping providers.

Ambulance diversions following public hospital emergency department closures.
The purpose of this study was to examine whether hospitals are more likely to temporarily close their emergency departments to ambulances, through ambulance diversions, if neighboring diverting hospitals are public vs private. Results showed that sample hospitals respond differently to diversions by neighboring public (vs private) hospitals. The authors conclude that these findings suggest that these hospitals might be strategically declaring ambulance diversions to avoid treating low-paying patients served by public hospitals.

A comparison of two structured taxonomic strategies in capturing adverse events in U.S. hospitals.
The purpose of this study was to compare the ability of AHRQ’s Quality and Safety Review System (QSRS) and the proposed triadic structure for the 11th version of the International Classification of Disease (ICD-11) to capture adverse events in U.S. hospitals. One thousand admissions were chosen for this study in a random sample from 3 general, acute care hospitals in Maryland and Washington D.C. and abstracted by two different sets of coding specialists for QSRS and the ICD-11. The results showed less than 20 percent agreement between QSRS and ICD-11 in their ability to identify the same adverse events. The sensitivity of ICD-11 improved when coders were given a list of potential adverse events. The authors conclude that in its draft form, ICD-11 has a limited ability to capture the same types of events as QSRS and that coders may need more training to improve its ability to identify adverse events.

State of research in adult hospital medicine: results of a national survey.
This study examined the state of research in academic hospital medicine by conducting a survey of members of the Society of Hospital Medicine (SHM). A total of 100 programs were considered eligible and surveys sent to corresponding individuals. Among those programs, 28 completed the survey. There was a total 1,586 faculty members represented with 12% identified as engaging or having obtained extramural funding with 41% as engaging in quality improvement efforts. Most of the programs (61%) received $500,000 or less and 29% received >$1 million in funding. The major federal funders were AHRQ, NIH, and the Veterans Health Administration. Only five programs currently have a research fellow program in hospital medicine, with many programs citing a lack of funding as the major barrier to establishing a program. Almost half of the respondents indicated their faculty were publishing between 11-50 peer-reviewed manuscripts each year.

Critical access hospitals and cost shifting.
In the context of ongoing discussion about critical access hospital (CAH) reimbursement, it is important to better understand how health care providers currently utilize funds from the CAH Programs. This study found that among hospitals converted to CAH designation while part of a hospital system, the relative proportion of costs that reflect shared services provided by the parent organization is significantly higher than would be expected in the post-conversion period.
