DRG calculation and utilization patterns: a review of method and policy.

This paper examines methodological and policy issues of interest to medical geographers who use diagnosis-related groups (DRGs) in their research. Methodological issues are studied in terms of the calculation of DRGs and variation in the utilization of surgical and medical DRGs. It is argued that a shift to a single DRG price system should first address the (i) regional disparities that currently exist and the need for large-scale indices of medical wages and labor costs; (ii) severity of illness measurements other than the present nominal ones; and (iii) wide variation among medical versus surgical procedures. The Department of Commerce's Economic Analysis Area is recommended to remedy the problem of geographic scale. Policy issues of interest to medical geographers center around the shift to greater hospital specialization which is likely to continue across the country. Inner-city, rural and teaching hospitals may continue to be inadequately reimbursed by DRGs, treat more medically indigent, or both. Medical geographers should be aware of the policy and methodological issues involved not only in DRGs, but in proposed prospective payment systems for ambulatory and long-term care.

HMO promotion and the privatization of health care in Chile.

Since 1973 the Chilean junta has privatized sectors of the national economy. This paper analyzes the country's policy process of promoting private medical programs through HMO-like plans (ISAPREs, or Institutes of Provisional Health). These plans have captured less than half of their originally anticipated market share. It is argued that the future performance of ISAPREs will be undermined by their limited maternal benefits, their targeting to a small upper-income group which cannot sustain many private medical programs, and competition with less expensive yet equally competent public medical programs. The paper briefly compares privatization in Chile with the experiences of other countries, and specifically contrasts the restructuring of health services under military rule in Chile with those of Argentina and Uruguay. The paper concludes that the Chilean experience with HMOs epitomizes the perils of planning health care during short-term periods of economic prosperity as well as failing to consult medical care providers and consumers.

Restructuring health care financing in Chile.

The current Chilean government adopted a neoclassical model of development and subsequently introduced various incentives for the privatization of medical care. This paper analyzes health care financing in Chile during the last decade and evaluates government efforts to minimize state-financed medical care. In so doing, this paper provides a framework for analyzing private vs public medical care delivery systems in developing countries. For this reason, the first section discusses the major attributes and issues of public and private delivery systems followed by a case study examining the origins, effectiveness and impact of the restructured health system in Chile.

A methodological note on location-allocation models.

Three conditions render the use of standard methodologies inappropriate in solving location-allocation problems. This paper presents one alternative method for assigning an emergency aircraft to one of three hospitals in northern Chile when standard approaches are not suitable. Graph analyses and the demographic potential measures are used in the case presented. The main advantages of this alternative approach are its computational ease and the use of more than one method.
