Outcomes of Pharmaceutical Therapy Program (OPT) Update: RFA HS-92-03 Projects: Study of Patient Outcomes Associated with Pharmaceutical Therapy (continued)

Outcomes of Pharmaceutical Therapy for HIV Disease

Principal Investigator: Richard D. Moore, M.D., Johns Hopkins University Baltimore, MD 21205
Grant Number: HS07809
Project Period: 02/93-01/98
NTIS Number: PB2000-100684

Summary:  The project developed a comprehensive, longitudinal, epidemiological database of more than 4,000 HIV-infected individuals who were followed for a total of more than 12,000 person-years.  A study published in the New England Journal of Medicine in 1994 showed racial disparities in the receipt of antiretroviral drug therapy and prophylactic therapy against one of the HIV complications. The article had a major public health policy impact.  The validity of the study was further enhanced by a followup article in the same journal that demonstrated clinical outcomes of HIV individuals are independent of race, gender and drug use behavior.

Patient Outcomes Associate with Antidepressant Drugs

Principal Investigator: Judith M. Garrard, Ph.D., University of Minnesota, Minneapolis, MN 55455-0381
Grant Number: HS07772
Project Period: 03/93-02/98
NTIS Number: PB2001-106533

Summary:  This prospective study examined the association between patient outcomes and antidepressant treatment of community-dwelling elderly with depressive symptoms.  The patient outcomes included health services utilization, and health and functional status, including mortality and quality of life.  Study results suggest under-detection of depression among the elderly.  Minor depression appeared associated with perception of a more negative health related quality of life compared to asymptomatic elderly.

Pharmaceutical Care and Pediatric Asthma Outcomes

Principal Investigator: Andreas S. Stergachis, Ph.D., University of Washington, Seattle, WA 98195
Grant Number: HS07834
Project Period: 03/93-02/97
NTIS Number: PB2000-101828

Summary:  This was a community-based, randomized controlled trial to demonstrate the effectiveness and cost-effectiveness of a pharmacist intervention program to enhance the outcomes of asthma care in children.  However, the final result failed to support the program's effectiveness.  It also raised a question on the value of conducting a randomized controlled trial when the assurance on protocol compliance could not be obtained.

Pharmaceutical Care Outcomes: The Patient Role

Principal Investigator: Betty Chewning, Ph.D., M.S., University of Wisconsin, Madison, WI 53706
Grant Number: HS07773
Project Period: 03/93-02/98
NTIS Number: PB2001-107624

Summary: This project examined from a patient's perspective the process and outcomes of arthritis patients' drug regimen decisions by seeing (1) how patients' perceptions about quality of life, symptoms, and medication benefits affect adherence and over-the-counter self-care use; (2) the effects of patient medication-taking behaviors on arthritis outcomes, including quality of life, clinical symptoms, and health care utilization; and (3) how patients' perceptions of quality of life vary with their clinical symptoms.  Individuals were interviewed (over the phone and in the clinic); client diaries reviewed; pharmacy patient profiles collected; and laboratory and physical measurements taken.  In addition, the investigators examined whether the AIMS2 and SF-36 differed in their sensitivity to changes in clinical symptoms.  Research found that while physicians ordered a medication change every 6 months for over 90 percent of the patients, many patients engaged in self-care without input from health care providers or at times intentionally deviated from prescribed regimens.  Overall, findings suggest that patients' pharmaceutical care behaviors appear relatively safe in terms of their clinical status indicators related to arthritis.

Use of Record Linkage to Study Outcomes of Drug Therapy

Principal Investigator: Richard Platt, M.D., M.S., Brigham and Women's Hospital, Boston, MA 02115
Grant Number: HS07821
Project Period: 08/93-07/98
NTIS Number: PB99-124042

Summary: This project sought to evaluate patient adherence to antihypertensive therapy in a managed care setting using a variety of methodologies including patient self-report, microelectronic technology in the medication container, pharmacy dispensing records, and pill counts.  By using relatively new microelectronic technology, the project aimed at achieving four major objectives: developing a standard definition of adherence; validating other alternative methods of adherence assessment such as patient-reports, pharmacy dispensing records, or pill counts; evaluating the relationship between adherence and a target medical condition; and examining the predictors of adherence.  The target condition was hypertension. Research was conducted in a managed care setting.  Adherence levels determined from pill counts and pharmacy dispensing records correlated more closely with quantity than with dose timing; and patient-reported non-adherence was a valid predictor of reduced adherence.

A Health Status Measure to Evaluate Drug Therapy for PCP

Principal Investigator: Albert W. Wu, M.D., M.P.H., Johns Hopkins University, Baltimore, MD 21205
Grant Number: HS07824
Project Period: 09/93-08/95
NTIS Number: PB96-182555

Summary:  As the first study in developing and using a health status measure in a clinical trial of an AIDS-related complication, this project was designed to demonstrate the reliability, validity, and usefulness of such a brief health status measure for acute Pneumocystis carinii pneumonia.  Unlike traditional methodology studies in the field, this project added two new dimensions, namely, responsiveness and clinical utility, in the evaluation of a health status instrument.  By doing so, the project has enhanced the traditional validation approach that was based exclusively on reliability and validity of the instrument and set a new model for future studies in the field.

Cognitive Impairment and Medication Appropriateness

Principal Investigator: Joseph T. Hanlon, Pharm.D., Duke University Medical Center, Durham, NC 27710
Grant Number: HS07819
Project Period: 03/93-05/95
NTIS Number: PB96-116223

Summary: Built on a series of secondary data analyses using the longitudinal data from a representative sample of community-dwelling elderly, the project evaluated the relationship between cognitive status and medication use.  Focused on two classes of commonly used medications in the elderly, the study demonstrated, in a dose-response fashion, that current benzodiazepine use is associated with memory impairment while NSAID use is not.  The study also provided some clues to the pattern of medication use after the elderly develop cognitive impairment.  In general, those elderly were less likely to use over-the-counter medications and analgesics than cognitively intact community-dwelling elderly.

Preference Assessment for Pharmaceutical Evaluation

Principal Investigator: Alan Garber, M.D., Stanford University, Stanford, CA 94305-8715
Grant Number: HS07818
Project Period: 03/93-08/96
NTIS Number: PB97-134431

Summary: The underlying economic principles for the preference assessment, which serves as the foundation for quality of life (QOL) measurement, are somewhat complicated.  Aimed at increasing a subject's understanding of the preference assessment instrument and to detect inconsistencies in response, the project developed a computer-based multimedia presentation of health states and preference elicitation to provide support for the preference assessment process.  The project demonstrated the validity, reliability and usefulness of this multimedia presentation.  In addition, the project also found that when a subject assigns a preference to a health state, that preference appears to be affected by the subject's current health state.

Pharmaceutical Cost, Use, and Outcome among Insured Elderly

Principal Investigator: Laura B.Gardner, M.D., Ph.D., M.P.H., Axiomedics Research, Inc., Los Altos, CA 94022-3611
Grant Number: HS08217
Project Period: 09/93-08/96
NTIS Number: PB97-165856

Summary:  The study database was a group of 19,350 retirees of the Public Employees Retirement System (PERS) who were demographically representative of the general Medicare population.  The database maximized its epidemiological potential by linking with Medicare claim data of the PERS individuals. Based on this combined database, the study found that none of the prescription co-payment options, except 50 percent prescription co-payment, affected utilization of and expenditures for pharmaceuticals and their generic substitutions.  Furthermore, none of those co-payment options produced observable changes on subsequent use and expenditures of medical care services among the retirees.

Statistical Methods for Quality-of-Life Outcomes Research

Principal Investigator: Marcia Anne Testa, Ph.D., Harvard School of Public Health, Boston, MA 02115
Grant Number: HS07767
Project Period: 03/93-02/97
NTIS Number: PB98-115421

Summary:  The investigators 1) evaluated and analyzed current and potential measurement and statistical techniques used in assessing quality-of-life-related patient outcomes through a review of the literature; 2) refined existing analytical and statistical methodology so that it was appropriate for evaluation of pharmacologic therapies; and 3) developed clinical trials databases of hypertension, diabetes, and human immunodeficiency virus.  Research results formed the basis for the National Committee for Quality Assurances' (NQCA) Quality Dividend Calculator (QDC), which helped to establish both clinical and fiscal benefits to improving diabetes.  Additionally, guidelines for design and analysis were published for quality of life consideration in AIDS clinical trials.
