  • Economic Profiling of Physician Specialists

    Open AccessJ W Thomas, Kathleen WardARTICLEINQUIRY The Journal of Health…2006

    This paper examines the influence of episode attribution methodology and cost outlier methodology on the accuracy of physicians' economic profiles. Four years of claims data from a mixed model HMO were processed using the leading episode grouper software. Episode grouped results then were applied to construct input distributions for a simulation model. For each of four specialties (cardiology, family practice, general surgery, and neurology), we …

  • Comparing Accuracy of Risk-Adjustment Methodologies Used in Economic Profiling of Physicians

    Open AccessJ W Thomas, Kyle L Grazier et al.ARTICLEINQUIRY The Journal of Health…2004

    This paper examines the relative accuracy of risk-adjustment methodologies used to profile primary care physician practice efficiency. Claims and membership data from an independent practice association health maintenance organization (HMO) were processed through risk-adjustment software of six different profiling methodologies. The Group R2 statistic was used to measure, for simulated panels of HMO members, how closely each methodology's cost pr…

  • Accuracy of Risk-Adjusted Mortality Rate As a Measure of Hospital Quality of Care

    J W Thomas, Timothy P HoferARTICLEMedical Care1999Referencias: 12

    OBJECTIVES: Reports on hospital quality performance are being produced with increasing frequency by state agencies, commercial data vendors, and health care purchasers. Risk-adjusted mortality rate is the most commonly used measure of quality in these reports. The purpose of this study was to determine whether risk-adjusted mortality rates are valid indicators of hospital quality performance. METHODS: Based on an analytical model of random measur…

  • Interpreting Risk-Adjusted Length of Stay Patterns for VA Hospitals

    J W Thomas, ELIZABETH W BATES et al.ARTICLEMedical Care1998Referencias: 13

    OBJECTIVES: The Veterans Health System must become more competitive with the private sector in terms of efficiency of care. Studies have shown significantly longer lengths-of-stay (LOS) in facilities operated by the Department of Veterans Affairs (VA) compared with private sector facilities. Most comparisons, however, have not controlled well for casemix differences or have involved small numbers of patients. The aims of this study were: (1) cont…

  • HMO Marketing and Selection Bias

    Richard Lichtenstein, J W Thomas et al.ARTICLEMedical Care1992

    The research evidence indicates that health maintenance organizations (HMOs) participating in the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA) At-Risk Program tend to experience favorable selection. Although favorable selection might result from patient decisions, a common conjecture is that it can be induced by HMOs through their marketing activities. The purpose of this study is to examine the relationship between HMO marketing stra…

  • Investigating Early Readmission as an Indicator for Quality of Care Studies

    J W Thomas, James J HollowayARTICLEMedical Care1991

    Readmission to a hospital shortly following a previous discharge may be viewed as an adverse outcome of care. Consequently, early readmission represents a potentially useful indicator for monitoring quality. While a number of recent research studies have focused on this issue, several important questions concerning appropriate use of early readmission as a quality of care indicator remain to be addressed. In this article, using data on all discha…

  • Selection Bias in Tefra At-Risk HMOs

    Richard Lichtenstein, J W Thomas et al.ARTICLEMedical Care1991

    The issue of selection bias was investigated using data from 22 HMOs who are enrolling Medicare beneficiaries under Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA) at-risk contracts. The study differs from previously published analyses of this issue in that it deals with the current Medicare risk program (TEFRA) rather than with earlier Demonstration Programs; as an indicator of selection bias, it utilizes beneficiary functional health s…

  • The Strassburg Alexander and the Munich Oswald. Precourtly Adventure of the German Middle Ages

    Albrecht Classen, J W ThomasARTICLEGerman Studies Review1990

    The Strassburg and the Munich Oswald, heretofore never translated into English, were written during the third quarter of the twelfth century, a time when German narrative verse was beginning to escape the domination of the Church and appeal primarily to the secular interests of the public. The Alexander is a version of one of the most popular stories of antiquity and all time. The Munich too is based on the deeds of an important historical figure…

  • Including Health Status in Medicare??s Adjusted Average per Capita Cost Capitation Formula

    J W Thomas, Richard LichtensteinARTICLEMedical Care1986

    Actuarial factors currently comprising Medicare's HMO capitation formula, the Adjusted Average Per Capita Cost (AAPCC), are considered by many researchers to be inadequate as predictors of future period health care costs. While it is often suggested that the formula should incorporate beneficiary health status, no measure of health status suitable for this purpose has yet been identified. The authors present initial results from a study of 1,934 …

  • Detecting and preventing adverse drug interactions

    Open AccessDuane M Kirking, J W Thomas et al.ARTICLESocial Science & Medicine1986Referencias: 2

    For patients taking two or more medications concurrently, interactions among the drugs can cause undesirable effects or negate desired responses. In modern pharmacy practice, an important role of the pharmacist is to detect potentially harmful interactions and take appropriate action to prevent their occurrence. Pharmacy computer systems offer potential for improving pharmacists' effectiveness in the detection and followup of drug interactions. B…

  • Relating Satisfaction With Access to Utilization of Services

    J W Thomas, Roy PenchanskyARTICLEMedical Care1984

    Underlying the continuing emphasis on access by health services researchers and policymakers is the assumption that patients having poorer access will receive less than appropriate health care, other things being equal. However, recent research results typically have not supported this assumption, and the nature and importance of relationships between access and use still remain unclear. Most published studies have sought to define general relati…

  • Classification of Hospitals Based on Measured Output

    J W Thomas, S E Berki et al.ARTICLEMedical Care1983

    Evaluation of hospital performance and improvement of resource allocation in hospital systems require a method for classifying hospitals on the basis of their output. Previous approaches to hospital classification relied largely on input characteristics. The authors propose and apply a procedure for classifying hospitals into groups where within-group hospitals are similar with respect to output. Direct measures of case-mix-adjusted discharges an…

  • The Concept of Access

    Roy Penchansky, J W ThomasARTICLEMedical Care1981

    Access is an important concept in health policy and health services research, yet it is one which has not been defined or employed precisely. To some authors "access" refers to entry into or use of the health care system, while to others it characterizes factors influencing entry or use. The purpose of this article is to propose a taxonomic definition of "access." Access is presented here as a general concept that summarizes a set of more specifi…

  • Wigalois, the Knight of Fortune's Wheel

    Carla Love, Wirnt von Grafenberg et al.ARTICLEModern Language Notes1979

    The Arthurian verse-novel Wigalois, written by the German knight Wirnt von Grafenberg in the early years of the thirteenth century, tells a story which was well known in the medieval period, appearing in eight versions of four languages. This first English translation makes accessible to a new audience the adventure-filled tale of the hero's knightly education and quest for honor, and his ultimate recognition of Sir Gawain as his long-lost father…
