OBJECTIVE To develop an automated, data-driven, and scale-flexible method to delineate hospital service areas (HSAs) and hospital referral regions (HRRs) that are up-to-date, representative of all patients, and have the optimal localization of hospital visits. DATA SOURCES The 2011 state inpatient database in Florida from the Healthcare Cost and Utilization Project. STUDY DESIGN A network optimization method was used to redefine HSAs and HRRs by maximizing patient-to-hospital flows within… Expand
Automated delineation of hospital service areas as a new tool for health care planning.
A new, fully automated, objective, and reproducible method for delineating hospital service areas for Switzerland provides a useful tool for hospital services researchers that will enable them to delineate and update patient-flow-based HSAs. Expand
Automated delineation of cancer service areas in northeast region of the United States: A network optimization approach.
Deriving cancer-specific service areas with an automated algorithm that uses empirical and network methods showed improved performance on geographic measures compared to more general, hospital-based service areas. Expand
Evaluating the effectiveness of the Hospital Referral Region (HRR) boundaries: a pilot study in Florida
Whether the HRR boundaries have significantly varied over time in Florida is evaluated to evaluate whether the HRRs hold values for a variety of health policy themes, including hospital policy-making, optimization of healthcare systems, and measurement of competition in healthcare markets. Expand
Comparing methods of grouping hospitals.
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, and may offer a better choice for efforts seeking to analyze the behaviors and dynamics of groups of hospitals.

Network optimization approach to delineating health care service areas: Spatially constrained Louvain and Leiden algorithms
Between the two, the ScLeiden performs better than ScLouvain in modularity, localization index and computational efficiency, and thus is recommended as an effective and efficient approach for defining functional regions. Expand
Network-Based Delineation of Health Service Areas: A Comparative Analysis of Community Detection Algorithms
This work compared HSA delineations produced by community detection algorithms using a large-scale dataset containing different types of hospital-patient discharges spanning a 7-year period in US, and suggested that Infomap may be a more suitable community detection for Hsa delineation since it finds a high number of HSAs with high localization index and a low network conductance.

Using Weighted Hospital Service Area Networks to Explore Variation in Preventable Hospitalization
Use of weighted‐HSANs permitted identification of small hospitals with particularly high rates of admission and influenced performance ranking of hospitals, particularly those with a broadly distributed patient base. Expand
Association of Shared Care Networks with Heart Failure Excessive Hospital Readmissions
Higher-than-expected HF readmissions were associated with shared care networks and control mechanisms such as the HRRP may need to characterize and reward shared care to guide hospitals towards a more organized HF care system. Expand
Spatial Behavior of Cancer Care Utilization in Distance Decay in the Northeast Region of the U.S.
The best-fitting distance decay function is derived to capture the spatial behaviors of cancer patients in the Northeast region of the U.S., and examines and explains the spatial variability of such behaviors across sub-regions. Expand

A hybrid algorithm for the service area problem is proposed by extending iterative local search (ILS) algorithm with three schemes: population-based ILS, variable neighborhood descent (VND) search, and set partitioning. Expand


Delineating Hierarchical Hospital Service Areas in Florida
Abstract Hospital service area () and hospital referral region (), known as a hierarchical system, have been used as analysis units in a growing body of large‐scale studies of healthcare spending,Expand
Do Hospital Service Areas and Hospital Referral Regions Define Discrete Health Care Populations?
HSAs and HRRs are geographic units commonly used in health services research yet vary in their ability to describe where patients receive hospital care, and Geographic models may need to account for differences between emergent and nonemergent care. Expand
Hospital service areas – a new tool for health care planning in Switzerland
The methodology to create and characterize population-based hospital service areas (HSAs) for Switzerland and introduced novel planning variables extracted from the patient origin study to understand patient travel patterns for hospital use is presented. Expand
Evaluating and re-demarcating the Hospital Service Areas in Florida
Abstract The Hospital Service Areas (HSAs) better portray underlying local patterns of hospitalization than administrative units, and offer a promising analysis unit for studies of healthcare market.Expand
Do pediatric hospitalizations have a unique geography?
A cross-sectional analysis of California hospital discharges for two age groups – non-newborns 0–17 years old, and seniors, finds a poorer fit of the traditional geographic system for children. Expand
Comparing local and regional variation in health care spending.
This analysis suggests that HRR-based policies may be too crudely targeted to promote the best use of health care resources and suggests that payment reforms in reducing overutilization while maintaining access to high-quality care depends on the effectiveness of targeting. Expand
Hospitals, market share, and consolidation.
Local governments may want to introduce new policies that help ensure consumers gain protection in the event of consolidation, such as insurance products that charge consumers more for high-priced clinicians and health care centers, bundling payments to clinicians and medical centers to eliminate the incentives of big institutions to simply provide more care, and establishing area-specific price or spending targets.

Constructing Geographic Areas for Cancer Data Analysis: A Case Study on Late-stage Breast Cancer Risk in Illinois.
This research proposes a regionalization approach to mitigate the small population problem by constructing larger areas in GIS that are more coherent than geopolitical areas or arbitrary zip code area and census units in terms of attribute and spatial closeness. Expand
Appropriate measures of hospital market areas.
Market areas are compared based on various descriptions using data on California hospitals and patient discharge abstracts to provide a framework for evaluating which definitions of hospital market areas are suitable for various types of analyses. Expand
