Purpose According to the principle of equivalence of care, health care in prison has to be of the same standard and quality as in the general population. This study aims to determine the geographic accessibility of dialysis services for older prisoners and the older general population in Switzerland and whether accessibility and availability of dialysis care are equivalent. Design/methodology/approach Spatial accessibility analysis incorporated four different data types: population data, administrative data, street network data and addresses of prisons and hemodialysis services. Findings Analysis revealed that the average travel time to the nearest dialysis service was better for prisoners (11.5 min) than for the general population (14.8 min). However, dialysis service for prisoners is hampered by the necessary lead-time in correctional settings, which, ultimately, leads to longer overall access times (36.5 min). Accordingly, the equivalence of dialysis care for older Swiss prisoners is not entirely respected for availability and accessibility. Originality/value The strength of the study lies in the combination of ethical principles and the highly tangible results of a spatial accessibility analysis. The ethics-driven empirical analysis provides arguments for policy-makers to review the current practices.

Zip Code

Purpose: This study compares and contrasts locational identification (physician practice ZIP code) between several physician demographic databases and a research team-verified ZIP code to determine spatial concordance. Accuracy of physician location data is critical for both successful national physician workforce planning and for assessing the fulfillment of distinct regional medical school missions. Methods: Three physician databases; the American Medical Association’s Physician Masterfile, the National Provider and Plan Enumeration System (NPPES), and the Minnesota Board of Medical Practice’s Licensure File were compared against each other as well as a set of actively verified practice location ZIP codes.  A sampling frame of medical school alumni from 2003 to 2014 was selected. The sample included alumni from both regional and main campuses. From this alumni sample, a random sample of four hundred individuals were selected for closer examination. Descriptive frequencies are presented for the concordance of ZIP codes for the sample of four hundred alumni. Findings: From an initial cohort of 2,605 University of Minnesota medical school alumni, a sample of 400 who also possessed a Minnesota medical license were randomly selected to examine concordance rates. The highest rate of concordance was the verified ZIP code and the Minnesota Licensure Board practice ZIP code at 68.8%. Only 42.0% of practice location ZIP codes matched across all databases. Conclusions: The concordance rate across practice ZIP codes in the databases does not inspire confidence in ability to characterize true physician practice location. Some of the difficulties in defining, identifying and maintaining information on physician practice location are discussed. Without accurate and precise practice location information, the development and implementation of comprehensive national health policies for the United States may face difficulties. The lack of reliable physician practice location data also presents a challenge to regional medical school campuses that depend upon accurate physician location data to evaluate progress toward mission-directed workforce goals.

The Relationship

Abstract Background The aim of our study was to evaluate the allocation of dental resources and explore access to dental care in Taiwan. In addition, we tried to understand the spatiotemporal characteristics of dental care quality and analyze the relationship between dental care quality and areas with deficiencies in dental resources. Methods The study used a two-step floating catchment area to calculate the dental resources accessibility and explore the spatiotemporal distributions of dental care quality. The association between dental care quality and spatial accessibility was analyzed using a spatial error model. Results Most areas with deficient dental resources and lower dental care quality were remote townships, agricultural towns, or aging towns with spatial clustering. The quality of children's preventive dental care had increased over time. Most highly urbanized areas had higher dental care quality. The quality of some dental care types such as children's preventive care and full-mouth calculous removal was associated with higher accessibility. Conclusions Understanding the spatiotemporal distribution of both dental care accessibility and quality can assist in allocation of dental care resources. Adequate dental resources may elevate dental care quality. Suggestions include policies to balance dental resources and routinely monitor improvement in areas with deficient dental care.
