Authors: Burl Jeffrey B. , Bonner Alice , Rao Maithili , Khan Anwer M. 
Published: April 2015

OBJECTIVE: This study was undertaken to review the impact of utilizing geriatric nurse practitioner/physician (GNP/MD) teams on cost and utilization for a cohort of Medicare HMO enrollees residing in long‐term care facilities. The results would be used by the organization for further development of the GNP Program.DESIGN: A 1‐year retrospective data analysis on revenues and cost for 1077 HMO enrollees residing in 45 long termcare facilities.SETTING: Proprietary and not‐for‐profit, licensed long term care facilities in the HMO's service area of central Massachusetts. Facilities in the study had both skilled (Medicare‐certified) and custodial beds.MEASUREMENTS: Data were collected retrospectively on overall cost, revenues, emergency department (ED) transfers, hospital, and subacute days.RESULTS: Of 1077 residents, 414 were cared for by GNP/MD teams compared with 663 by physicians alone. Acute care and ED costs were significantly lower for the GNP/MD‐covered patients. There was a gain of $72 per resident per month (PRPM) with the GNP/MD‐covered patients compared with a loss of $197 PRPM for physicians alone. There were no significant differences in ancillary services or prescriptions.CONCLUSION: The use of GNPs in collaboration with physicians reduced ED and acute care utilization costs as well as overall costs for a cohort of HMO enrollees in long‐term care. This encouraged the HMO to support the concept that all long‐term care HMO residents should be covered by GNP/MD teams.
Prescribing Exercise Intensity for Older Women
Authors: Kohrt Wendy M. , Spina Robert J. , Holloszy John O. , Ehsani Ali A. 
Published: April 2015

OBJECTIVE: For the purpose of prescribing exercise intensity, the American College of Sports Medicine (ACSM) provides guidelines for relating the perceived level of exertion and the heart rate (HR) response during exercise, expressed either as a percentage of maximal HR or of HR reserve, to a percentage of maximal aerobic power (VO2max). However, because maximal HR and V̇O2max decline with age, it is possible that these guidelines are not appropriate for an older population. The purpose of this study was to evaluate in 60‐to 72‐year‐old women the relationships among the common methods of prescribing exercise intensity.DESIGN: Participants were 112 healthy but sedentary women, aged 66 ± 4 years, who performed treadmill walking at four speeds.SETTING: Subjects were recruited from the community, and exercise tests were performed at a university laboratory facility.MEASUREMENTS: V̇O2max and maximal HR were determined during treadmill walking. The HR and V̇O2 responses to walking 6 minutes at each of four speeds ranging from 67 to 107 m/min, along with ratings of perceived exertion (RPE) and plasma lactate levels, were determined on a separate day.RESULTS: The exercise bouts required an average of 55 ± 10%, 64 ± 12%, 77 ± 12%, and 91 ± 9% of V̇O2max. Corresponding HR values were 64 ± 8%, 70 ± 9%, 81 ± 10%, and 92 ± 7% of maximal HR, and they were within the expected ranges based on ACSM guidelines. HR values as a percentage of HR reserve were much lower than expected based on the guidelines. RPE values were lower than expected at a given %V̇O2max, and plasma lactate levels were also relatively low, suggesting that older women are able to exercise at a higher percentage of V̇O2max than levels currently recommended.CONCLUSIONS: The results indicate that HR expressed as a percentage of maximal HR is an appropriate method of prescribing exercise intensity in healthy, sedentary 60‐ to 72‐year‐old women. The HR reserve method is not recommended in this population because it will likely result in the exercise being performed at a higher than expected percentage of V̇O2max.
Coronary Heart Disease Risk Factors of Vigorously Active Sexagenarians and Septuagenarians
Authors: Williams Paul T. 
Published: April 2015

OBJECTIVE: To examine the dose‐response relationship between coronary heart disease risk factors and vigorous exercise in older men.DESIGN: Physician‐supplied medical data were compared with running distance and performance in a national cross‐sectional survey of 175 septuagenarian, 935 sexagenarians, and 8672 younger male runners.RESULTS: Older runners ran significantly more slowly than younger runners. Nevertheless, men 60 years of age and older who ran further had significantly higher plasma high‐density lipoprotein (HDL)‐cholesterol concentrations (regression slope ± SE: 0.16 ± 0.02 mg/dL per km/week, P < .001), and significantly lower ratios of total cholesterol to HDL‐cholesterol (−0.009 ± 0.002 per km/week, P < .001), plasma triglyceride concentrations (−0.309 ± 0.107 mg/dL per km/week, P ≤ .004), systolic and diastolic blood pressures (−0.066 ± 0.028, and −0.042 ± 0.016 mm Hg per km/week, respectively, P ≤ .02), body mass indices (−0.039 ± 0.004 kg/m2 per km/week, P < .001), and waist circumferences (−0.107 ± 0.010 cm per km/week, P < .001). Better 10‐kilometer race performance times were also associated (P ≤ .001) with higher HDL‐cholesterol levels and lower adiposity, blood pressure, triglycerides, and ratios of total cholesterol to HDL‐cholesterol levels. Septuagenarians who ran faster and further also had significantly (P ≤ .03) higher HDL‐cholesterol, lower ratios of total cholesterol to HDL‐cholesterol, and slimmer waists. Compared with those less than age sixty, older runners had significantly greater calculated reductions in waist (P = .039) and chest circumferences (P = .009) but significantly less reduction in low‐density lipoprotein (LDL) cholesterol (P = .020) per kilometer run per week.CONCLUSIONS: Age does not limit the potential for vigorous activity to increase HDL‐cholesterol or to reduce blood pressure, adiposity, or triglycerides, but it may attenuate improvements in LDL‐cholesterol. Sexagenarians and septuagenarians are expected to have reduced heart disease risk in proportion to their vigorous activity.

OBJECTIVE: To examine demographic and clinical features of older AIDS patients in comparison with younger individuals.DESIGN: Data base review.SETTING: Maryland AIDS Registry from 1981 through the end of 1994.PARTICIPANTS: All registered Maryland AIDS cases greater than or equal to 60 years of age at diagnosis and all Maryland AIDS cases aged 20 to 39.MAIN OUTCOME MEASURES: Demographic features, mode of transmission and change in mode over time, clinical presentations, CD4+ counts, and survival time.RESULTS: A total of 321 (2.7%) AIDS cases diagnosed in Maryland were people 60 years of age or older compared with 7511 cases (63.9%) in people aged 20 to 39 years. The proportion of whites was higher in the older group, but the gender distribution was similar to younger counterparts. Transfusion was the primary cause of exposure of 32% of the older people with AIDS; however, during the last few years, sexual transmission and drug abuse have been implicated more frequently. Twelve percent of older patients had no reported risk factors compared with 4% of younger AIDS patients. The most common presenting AIDS indicator disease in older cases was Pneumocystis carinii pneumonia. Wasting syndrome, candidiasis, and HIV encephalopathy also occurred frequently. Median life span was 9 months compared with 22 months in the young.CONCLUSION: Our study demonstrates that transfusion is no longer the leading cause of AIDS in older people in Maryland. The relatively increased prominence of transmission by other modes in this age group raises the importance of preventive and educational measures. Older patients generally have a shorter survival than younger individuals.

Published: April 2015

OBJECTIVES: To determine the prevalence rates of self‐reported sleep complaints and their association with health‐related factors.DESIGN: A cross‐sectional study.SETTING: People living in the community.PARTICIPANTS: A total of 2398 noninstitutionalized individuals, aged 65 years and older, residing in the Veneto region, northeast Italy.MEASUREMENTS: Odds ratios for the association of sleep complaints with potential risk factors.RESULTS: The prevalence of insomnia was 36% in men and 54% in women, with increased risks for women (odds ratio (OR) = 1.69, 95% CI: 1.3–2.1), depression (OR = 1.93, 95% CI, 1.5–2.5), and regular users of sleep medications (OR = 5.58, 95% CI, 4.3–7.3). About 26% of men and 21% of women reported no sleep complaints. Night awakening, reported by about two‐thirds of the participants, was the most common sleep disturbance. Women and regular users of sleep medications had significantly increased odds for insomnia and for not feeling rested upon awakening in the morning. Depressive symptomatology was more strongly associated with insomnia and night awakening than with awakening not rested, whereas physical disability was more strongly associated with awakening not rested than with the other two sleep disturbances.CONCLUSION: Our findings show that sleep complaints, highly common among older Italians, are associated with a wide range of medical conditions and with the use of sleep medications. Further longitudinal studies are needed to investigate the causes and the negative health consequences of sleep disturbances to improve both the diagnosis and treatment.

OBJECTIVE: To describe provider practice patterns in the diagnosis and treatment of Nursing Home‐Acquired Pneumonia (NHAP) and to document associations with cure, mortality, and transfer.DESIGN: A retrospective cohort.SETTING: Six nursing homes in Seattle, Washington.PARTICIPANTS: A total of 94 patients, 65 years of age or older (mean 83 ± SD 9), in whom the diagnosis of pneumonia was documented in the nursing home medical record between July 1, 1994, and June 6, 1995.MEASUREMENTS: Multivariate logistic regression was used to assess the relationship between descriptive, diagnostic, or therapeutic measures and three outcomes, cure, 30‐day mortality, and hospital transfer.RESULTS: Ninety‐four episodes of pneumonia were identified. Allowing for more than one outcome per patient, there were 71 (75.5%) cures, 16 (17%) deaths, and nine (9.6%) transfers. Eighty‐five percent of patients identified as having NHAP by their providers had chest X‐rays (CXRs), and 69% had physical examinations. Sputum examination was ordered in 5%, blood cultures in 6%, and white blood cell counts in 33% of patients. In multivariate analysis, patients with functional decline were more likely to die (Odds Ratio (OR) 36.5 (95% CI 6.1, 220)). Cognitive decline was a risk factor for mortality (OR 6.8 1 (CI 1.8, 26)) and transfer (OR 7.5 (CI 1.2, 46)). Those patients receiving only oral antibiotics (OR 3.2 (CI 1.1, 9.7)) were more likely to be cured. Length of therapy >1 week was also associated with cure (OR 2.9 (CI 1.0, 8.6)). Providers with Certificate of Added Qualifications (CAQ) in Geriatric Medicine were more likely to achieve cure (OR 3.1 (CI 1.0, 9.0)).CONCLUSIONS: Most patients with NHAP had diagnostic CXRs and physical examinations. In multivariate analysis, death was more likely to occur in patients with cognitive or functional decline. Cure was associated with the use of oral antibiotics alone and with care by providers with CAQ in Geriatric Medicine.
Newer Psychotropic Medication Use in Nursing Home Residents
Authors: Lasser Robert A. , Sunderland Trey 
Published: April 2015

OBJECTIVE: To evaluate the use of newer psychotropic agents in nursing home residents in the era of new Health Care Financing Administration (HCFA) guidelines.DESIGN: Retrospective chart review of referrals to an on‐site geriatric psychiatry service in seven Eastern Massachusetts facilities during 1995–1996.SUBJECTS: The 298 patients examined included 226 women and 72 men with a mean (SD) age of 81.9 (9.4) years.MEASUREMENTS: Patient demographics, psychiatric history and medical diagnoses, prescribed medication information, and mental status examination results were recorded systematically. Descriptive statistics of demographics, medication use, and dosing were generated, and comparative analyses were performed by chi‐square, ANOVA, and Tukey's tests.RESULTS: Overall, 69% of subjects were taking at least one psychotropic medication. Although benzodiazepines (32%) and antipsychotics (42%) were used by a large portion of subjects, antidepressants (61%) were the most commonly prescribed psychotropic, with 53% taking serotonin reuptake inhibitors. The atypical antipsychotic, risperidone, accounted for more than 30% of antipsychotic prescriptions. Low rates of anticholinergic use and low doses and rates of tricyclic antidepressant use were found in Alzheimer's disease patients. Mean dosing of the psychotropic agents fell within HCFA guidelines.CONCLUSIONS: Newer‐generation psychotropics have had a significant impact on the prescribing practices of primary physicians in treating nursing home residents. Of clinical importance is the high rate of antidepressant use in a population that has traditionally received inadequate pharmacotherapy for depression. More studies are needed to examine a shift to the use of other psychotropic drugs in this population in the post‐HCFA area.

Published: April 2015

OBJECTIVE: To examine correlates of high overall level of emotional functioning (emotional vitality) in disabled older women.DESIGN: A community‐based study: The Women's Health and Aging Study.POPULATION: A total of 1002 moderately to severely disabled women aged 65 and older living in the community.MEASUREMENTS: Emotional vitality was defined as having a high sense of personal mastery, being happy, and having low depressive symptomatology and anxiety. Correlations with demographics, health status, and social context were examined.RESULTS: Despite their physical disabilities, 35% of the 1002 disabled older women were emotionally vital. The percent of emotionally vital women declined with increasing severity of disability. After adjustment for disability status, a significantly increased likelihood for being emotionally vital was found for black race (OR = 1.69) and for having higher income (OR = 1.77), better cognition (OR = 2.36), no vision problems (OR = 1.61), adequate emotional support (OR = 2.54), and many face‐to‐face contacts (OR = 1.64). Having more than one negative life event reduced the likelihood of emotional vitality (OR = 0.57).CONCLUSION: A substantial proportion of even the most disabled older women can be described as emotionally vital. Findings also suggest that emotional vitality is not solely a function of stable, enduring individual characteristics but that health status, disability, and sociodemographic context also have an influence on emotional vitality.
Can We Afford Comprehensive, Supportive Care for the Very Old?

Published: April 2015

OBJECTIVE: To address the question, “Is there enough overuse of Medicare reimbursement to hospitals that reallocation of excess could provide sufficient funds to enhance home care and community services?”DESIGN: Simulation using data from the Medicare Current Beneficiary Survey (MCBS) to estimate dollars that might be reallocated from hospital reimbursement.PARTICIPANTS: A total of 3577 persons aged 80 and older in a stratified sample of Medicare beneficiaries interviewed in September 1992 in the MCBS.MEASUREMENTS: We ranked the United States hospital service areas' (HSAs) Medicare hospital discharge rates. We assigned the beneficiaries in the MCBS to the HSAs based on their residence zip codes. The hospitalization expenditures and mortality rates of MCBS respondents living in HSAs in each quartile were compared.RESULTS: By reducing hospital utilization to the mean level now used by the lowest quartile of HSAs, $560 would be saved per Medicare beneficiary aged 80 or older (P =.004) with no difference in mortality rates. These savings could purchase 40 visiting nurse visits per year for those in need. Potential savings would be $152 per Medicare beneficiary if hospital utilization were reduced from that used by the highest quartile to the level of the lower three quartiles of HSAs, enough to purchase about 11 additional visiting nurse visits.CONCLUSION: This simulation suggests that the very old might safely receive less hospital care. Because relatively few older people need home and community services in a year, these per capita savings could be reallocated to purchase many services for those having the greatest need.
Do Older Drivers with Visual and Cognitive Impairments Drive Less?
Authors: Stutts Jane C. 
Published: April 2015

OBJECTIVE: To determine whether older drivers with poorer cognitive and/or visual function drive fewer miles or avoid driving in situations that pose higher crash risks, such as at nighttime, in rush hour traffic, or when weather conditions are bad.DESIGN: A cross‐sectional data analysis conducted as part of a larger prospective study.SUBJECTS: A total of 3238 drivers aged 65 and older applying for renewal of their driver's license at one of eight participating North Carolina driver's license offices.MEASUREMENTS: Subjects were administered a battery of brief tests of cognitive and visual function, which included the Trail Making Test Parts A and B, the Short Blessed Orientation‐Memory‐Concentration test, and measures of high and low contrast visual acuity, contrast sensitivity, and peripheral vision. Participants were also asked to complete a brief driving survey containing questions about the number of miles they drove and whether they avoided driving under certain conditions, such as after dark or on busy, multi‐lane roadways. Driver age and gender were covariates in the analyses.RESULTS: Results of multivariate logistic regression models show a clear pattern of reduced driving exposure — lower annual miles and greater avoidance of high‐risk driving situations — associated with lower levels of cognitive and visual function. In general, the prevalence odds of reduced driving exposure were higher for the cognitive function variables than for the visual function variables, and higher for males than for females. Men who scored in the lowest quartile of performance on one of the cognitive tests were six to seven times more likely to report driving fewer than 3000 miles a year than were men scoring in the highest quartile, and women with low scores were one‐and‐one‐half to two times more likely to report driving less than 3000 miles than women with higher scores.CONCLUSIONS: While the findings of this study are reassuring, they do not guarantee that all drivers with cognitive and visual impairments are limiting their driving exposure appropriately, and geriatricians and other health professionals should be encouraged to evaluate their patients' cognitive and visual fitness for driving and provide counsel where indicated.
A Pelvic Muscle Precontraction Can Reduce Cough‐Related Urine Loss in Selected Women with Mild SUI

Published: April 2015

OBJECTIVES: To test the hypothesis that selected older women with mild‐to‐moderate stress urinary incontinence (SUI) can learn to demonstrate significantly reduced urine loss in 1 week by intentionally contracting the pelvic floor muscles before and during a cough (a skill we have termed “The Knack”).DESIGN: A prospective, randomized, single‐blind interventional study.SETTING: The Older American Independence Center, a federally sponsored research program affiliated with the University of Michigan in Ann Arbor, Michigan.PARTICIPANTS: Twenty‐seven women with a mean (SD) age of 68.0 (5.5) years, self‐reported SUI, and demonstrable urine loss during a deep cough.INTERVENTION: Women were randomized to an immediate intervention group (Group I: n = 13) who were taught the Knack after their first clinic visit, or a wait‐listed control group (Group II: n = 14) who were taught the Knack after 1 month.MEASUREMENTS: At 1 week after instruction, we tested the efficacy of the Knack in a standing stress test by (1) comparing the volumes of cough‐related urine loss leaked by all subjects, with and without use of the Knack, and (2) comparing the volumes of cough‐related urine loss leaked by Group I, using the Knack, with Group II, which had not yet been taught the Knack.RESULTS: Intra‐individual results showed that at 1‐week follow‐up, the Knack was used to reduce urine loss resulting from a medium cough by an average of 98.2%, compared with that of a similar cough performed 1 minute before without the Knack (P =.009); likewise urine loss was reduced by an average of 73.3% (P =.003) in a deep cough. Reduction in urine loss was not significantly correlated with a digital measure of pelvic floor muscle strength.CONCLUSION: Within 1 week, selected older women with mild‐to‐moderate SUI can acquire the skill of using a properly‐timed pelvic floor muscle contraction to significantly reduce urine leakage during a cough.

Published: April 2015

OBJECTIVE: To test the hypothesis that training‐related improvements in glucose and insulin responses to an oral glucose tolerance test (OGTT) are independent of changes in abdominal adiposity.DESIGN: Adiposity and responses to an OGTT were measured before and after a 4‐month randomized, controlled aerobic training program.SETTING: An academic medical institution.PARTICIPANTS: Sixteen healthy older (73 ± 1 year) men and women.INTERVENTION: Both the training (T) (n = 9) and control (C) (n = 7) groups exercised 4 times a week for 60‐minute sessions. T exercised on mini‐trampolines at 55 to 65% of HRmax (determined from a graded treadmill test) for 1 month and then at 75% for 3 months; C engaged in supervised stretching and yoga.MEASUREMENTS: At baseline and follow‐up, we estimated abdominal fat (from computed tomography and anthropometry), plasma glucose, and serum insulin responses to the OGTT and fasting concentrations of free fatty acids (FFA).RESULTS: Aerobic training resulted in a 16% increase in V̇2 peak and a 24% decrease in FFA in the T group (P <.05), but training had no effect on abdominal fat. In the T group, the glucose response curve shifted to the left, and the incremental area under the glucose curve decreased by 25% (P <.05). This improvement in glucose response occurred, however, only in those with impaired glucose tolerance at baseline and without any observed change in insulin response. No change in any variables occurred in the C group.CONCLUSIONS: Our data suggest that moderate‐intensity aerobic training has a favorable effect on glucose tolerance in older people, independent of changes in abdominal adiposity.
