    Title The Effects of Interdisciplinary Outpatient Geriatrics on the Use, Costs and Quality of Health Services in the Fee-for-service Environment.
    Date March 2009
    Journal Aging Clinical and Experimental Research

    To evaluate the effect of interdisciplinary outpatient geriatrics on the use, cost, and quality of health services in a fee-for-service (FFS) environment of two networks of primary care clinics operated by a not-for-profit provider organization in Dallas County, Texas.

    Title Differences in End-of-life Preferences Between Congestive Heart Failure and Dementia in a Medical House Calls Program.
    Date June 2004
    Journal Journal of the American Geriatrics Society

    OBJECTIVES: To compare end-of-life preferences in elderly individuals with dementia and congestive heart failure (CHF). DESIGN: Retrospective case-control study. SETTING: Geriatrician-led interdisciplinary house-call program using an electronic medical record. PARTICIPANTS: Homebound individuals who died while under the care of the house-call program from October 1996 to April 2001. MEASUREMENTS: Medical records review for demographics, functional status, advance medical planning, hospice use, and place of death. RESULTS: Of 172 patients who died in the program, 29 had CHF, 79 had dementia, 34 had both, and 30 had neither. Patients with CHF were younger (82.6 vs 87.0, P=.011) and less functionally dependent (activities of daily living score 9.1 vs 11.5, P=.001). Time from enrollment to death was not significantly different (mean+/-standard deviation=444+/-375 days for CHF vs 325+/-330 days for dementia, P=.113). A do-not-resuscitate (DNR) directive was given in 62% of patients with CHF and 91% with dementia (P<.001). Advance medical planning discussions were not significantly different (2.10 in CHF vs 1.65 in dementia, P=.100). More patients with CHF participated in their advance medical planning than those with dementia (86% vs 17%, P<.001). Hospice was used in 24% of CHF and 61% of dementia cases (P<.001). Finally, 45% of patients with CHF and 18% of patients with dementia died in the acute hospital (P=.006). Multivariate analysis showed that the fact that more patients with CHF were involved in their medical planning was not significant in predicting end-of-life preferences. Alternatively, Caucasian ethnicity was an independent predictor of having a documented DNR and death outside of the acute hospital. CONCLUSION: In the months before death, patients with CHF were more likely to have care plans directed at disease modification and treatment, whereas dementia patients were more likely to have care plans that focused on symptom relief and anticipation of dying. Several factors may contribute to this difference.

    Title Early Repolarization: an Electrocardiographic Predictor of Enhanced Aerobic Fitness.
    Date September 2000
    Journal The American Journal of Cardiology

    The presence or absence of early repolarization on the electrocardiogram at rest was correlated with aerobic exercise capacity in healthy volunteers from the Baltimore Longitudinal Study of Aging. Patients with early repolarization had both longer treadmill exercise duration and higher peak oxygen consumption than age-and gender-matched control subjects.

    Title The Relationship Between Aerobic Exercise Capacity and Circulating Igf-1 Levels in Healthy Men and Women.
    Date March 2000
    Journal Journal of the American Geriatrics Society

    OBJECTIVES: To determine whether aerobic capacity is associated independently with insulin-like growth factor-I (IGF-1) levels in healthy community-dwelling men and women. SETTING: The Baltimore Longitudinal Study on Aging (BLSA). DESIGN: A cross-sectional analysis of data from the population-based cohort of the Baltimore Longitudinal Study of Aging (BLSA). PARTICIPANTS: We studied 181 men and 92 women aged 20 to 93 years, volunteers in the Baltimore Longitudinal Study on Aging (BLSA). Subjects were free of endocrine, renal, hepatic, gastrointestinal, or cardiac diseases, and they were taking no medications known to interfere with the growth hormone-IGF-1 axis. MEASUREMENTS: All subjects underwent a single measurement of serum IGF-1 in the fasting state, as well as peak VO2 determinations during maximal treadmill exercise testing performed within one visit of the IGF-1 determination. Dual energy X-ray absorptiometry (DEXA) scans were performed in a subset of 171 subjects (64 women and 107 men) for determination of fat free mass (FFM). RESULTS: In the pooled group of women and men, univariate regression analysis revealed that age was correlated strongly with decreasing IGF-1 levels (r = -0.53, P < .001) and with peak VO2r = -0.56, P < .001). IGF-1 levels were also significantly correlated with peak VO2 (r = 0.29, P < .001). There were no significant gender-related differences in these relationships. On multivariate analysis, age (beta = -0.54, P < .001), but not peak VO2 (P = -0.01, P = .840), remained strongly associated with IGF-1 levels. After adjustment of peak VO2 for FFM in subjects with DEXA scans, results were similar. CONCLUSIONS: These findings indicate that although both peak aerobic capacity and circulating IGF-1 levels decline with age, aerobic capacity is not independently related to circulating IGF-1 in healthy men and women across the adult life span.

    Title Effectiveness of Diabetes Resource Nurse Case Management and Physician Profiling in a Fee-for-service Setting: a Cluster Randomized Trial.
    Journal Proceedings (baylor University. Medical Center)

    Nurses with advanced training-diabetes resource nurses (DRNs)-can improve care for people with diabetes in capitated payment settings. Their effectiveness in fee-for-service settings has not been investigated. We conducted a 12-month practice-randomized trial involving 22 practices in a fee-for-service metropolitan network with 92 primary care physicians caring for 1891 Medicare patients >/=65 years with diabetes mellitus. Each practice was randomized to one of three intervention groups: physician feedback on process measures using Medicare claims data; Medicare claims feedback plus feedback on clinical measures from medical record (MR) abstraction; or both types of feedback plus a practice-based DRN. The primary endpoint investigated was hemoglobin A(1c) level. Other measures were low-density lipoprotein (LDL) cholesterol level, blood pressure, annual hemoglobin A(1c) testing, annual LDL screening, annual eye exam, annual foot exam, and annual renal assessment. Data were collected from medical chart abstraction and Medicare claims. The number of patients with hemoglobin A(1c) <9% increased by 4 (0.9%) in the Claims group; 9 (2.1%) in the Claims + MR group (comparison with Claims: P = 0.97); and 16 (3.8%) in the DRN group (comparison with Claims: P = 0.31). Results were similar for the other clinical outcomes, with no differences significant at P = 0.10. For process of care measures, decreases were seen in all groups, with no significant differences in change scores. Quality improvement strategies must be evaluated in the appropriate setting. Initiatives that have been effective in capitated systems may not be effective in fee-for-service environments.
