The association of increasing resilience with positive health outcomes among older adults.

Our objective was to investigate three levels of resilience (low, medium, and high), identify associated characteristics, and measure the impact of increasing resilience on quality of life (QOL), healthcare utilization and expenditures, and preventive services compliance. The study sample was identified from adults age ≥65 who completed surveys during May-June 2019 (N=3,573). Other protective factors, including purpose-in-life, optimism, locus of control, and social connections, were dichotomized as high/low and counted with equal weighting (0 to 4). Among survey respondents, the prevalence of low, medium, and high resilience levels was 27%, 29%, and 44%, respectively. The strongest predictors of medium and high resilience included increasing number of other protective factors, lower stress, and no depression. Individuals with medium and high resilience had significantly higher QOL and lower healthcare utilization and expenditures. Resilience strategies integrated into healthy aging programming could be associated with improvements in QOL and/or healthcare utilization and expenditure outcomes.

The impact of internal locus of control on healthcare utilization, expenditures, and health status across older adult income levels.

Our objectives were to 1) determine the prevalence of locus of control (LOC) dimensions stratified by older adult income levels; 2) characterize internal LOC attributes within income subgroups; and 3) investigate LOC associations with healthcare utilization and expenditures; self-rated health and functionality. The survey sample was identified from adults age ≥65 years with diagnosed pain conditions. Internal LOC characteristics were determined from logistic regressions; outcomes regression-adjusted. Among respondents, internal prevalence for low (N = 554), medium (N = 1,394) and high income (N = 2040) was 27%, 30% and 30%, respectively. Internal was associated with high resilience, less stress, exercise and less opioid use across income levels. Lower-income internal was additionally associated with diverse social networks, physical therapy and less drug use. Those with high internal generally had lower healthcare utilization and expenditures; better self-rated health and functionality. Internal LOC is a powerful positive resource associated with better health outcomes, especially influential for lower income.

Characteristics associated with transition from opioid initiation to chronic opioid use among opioid-naïve older adults.

Our primary objective was to determine the prevalence and characteristics of opioid-naïve older adults who initiated opioids and transitioned to chronic use. Study populations included older adults ≥ 65years with continuous medical and drug plan enrollment one-year prior to opioid initiation (pre-period) through one-year after initiation (post-period). Characteristics were determined using multivariate logistic regression. Among eligible insureds (N = 180,498), 70% used only the initial opioid prescription; 30% continued to use opioids requiring ≥ 2 prescriptions with ≥ 15 days' supply. Overall, 6% transitioned to chronic use > 90days. Characteristics associated with chronic use included: (1) Low income, older, females, in poor health, with new/chronic back pain; (2) opioid initiation with long-acting opioids or tramadol; (3) prescriptions for other pain, sleep or antipsychotic medications; and (4) indications of pre and/or post mental health issues. Careful screening, monitoring and/or alternative non-opioid pain management strategies may be warranted for those at risk for chronic opioid use.

Characteristics of New-Onset and Chronic Sleep Medication Users Among Older Adults: A Retrospective Study of a US Medigap Plan Population using Propensity Score Matching.

BACKGROUND: Prescription sleep medications are often utilized to manage sleep problems among older adults even though these drugs are associated with multiple risks. OBJECTIVE: The aim was to determine the prevalence and characteristics of new-onset compared to chronic sleep medication users and to examine factors associated with the conversion from new to chronic use. A secondary objective was to investigate the impact of sleep medications on health outcomes of injurious falls and patterns of healthcare utilization and expenditures. METHODS: A 25% random sample of adults ≥ 65 years with 3-year continuous AARP® Medicare Supplement medical and AARP® MedicareRx drug plan enrollment was utilized to identify new-onset and chronic sleep medication users. Prescription sleep medication drugs were defined using National Drug Codes (NDCs); falls or hip fractures were identified from diagnosis codes. New users had no sleep medication use in 2014, but initiated medication use in 2015; chronic users had at least one sleep medication prescription in 2014 and in 2015; both groups had follow-up through 2016. Characteristics associated with new users, new users who converted to chronic use, and chronic users were determined using multivariate logistic regression. Prevalence of falls, healthcare utilization and expenditures were regression adjusted. RESULTS: Among eligible insureds, 3 and 9% were identified as new-onset and chronic sleep medication users, respectively. New-onset sleep medication prescriptions were often associated with an inpatient hospitalization. The strongest characteristics associated with new users, those who converted to chronic use, and chronic users were sleep disorders, depression and opioid use. About 50% of new users had > 30 days' supply; 25% converted to chronic use with ≥ 90 days' supply. The prevalence of falls for new-onset users increased by 70% compared to a 22% increase among chronic users. CONCLUSION: New-onset and chronic sleep medication users were characterized by sleep disorders, depression and pain. Addressing the underlying problems associated with sleep problems among older adults may decrease the need for sleep medications and thus reduce the risk of sleep medication-related adverse events.

The impact of mobility limitations on health outcomes among older adults.

The purpose of this study was to stratify an older adult population for subsequent interventions based on functional ability, and to estimate prevalence, characteristics and impact of mobility limitations on health outcomes. In 2016, surveys were sent to a stratified random sample of AARP® Medicare Supplement insureds; mobility limitations were defined using two screening questions. Responses were stratified to three mobility limitation levels. Multivariate regression models determined characteristics and impact on health outcomes. Among weighted survey respondents (N = 15,989), severe, moderate and no limitation levels were 21.4%, 18.4% and 60.3%, respectively. The strongest predictors of increased limitations included pain and poor health. Individuals with more severe limitations had increased falls, decreased preventive services compliance and increased healthcare utilization and expenditures. Utilizing two screening questions stratified this population to three meaningful mobility limitation levels. Higher levels of mobility limitations were strongly associated with negative health outcomes. Mobility-enhancing interventions could promote successful aging.

Purpose in Life and Positive Health Outcomes Among Older Adults.

Purpose in life (PIL) is conceptualized as having goals, a sense of direction, and a feeling that there is meaning to present and past life. PIL has been associated with positive health outcomes among older adults, including fewer chronic conditions, less disability, and reduced mortality. The purpose of this study was to estimate the prevalence of PIL among AARP Medicare Supplement insureds, identify associated characteristics, and measure impact on selected health outcomes. In 2016, surveys were sent to a random stratified sample; PIL was measured using a 7-item scale with 5 responses. Scores were averaged across responses and categorized to PIL levels of low, medium, and high. Survey responses were weighted to adjust for nonresponse bias and to weight to a nationally representative population. Multivariate regression models, adjusting for confounding covariates, were utilized to determine characteristics associated with PIL levels and the impact on health care utilization and expenditures, preventive services compliance and quality of life (QOL). Among weighted survey respondents (N = 15,680), low, medium, and high PIL levels were 24.2%, 21.1%, and 54.7%, respectively. The strongest characteristics of medium and high PIL included social support, resilience, reliance on faith, high health literacy, and good health status. Individuals with medium and high PIL had significantly lower health care utilization and expenditures, increased preventive services compliance, and higher QOL. PIL is strongly associated with improved mental and physical health outcomes among older adults. Thus, interventions to improve and/or maintain higher levels of PIL over time may promote successful aging.

Falls-Related Drug Use and Risk of Falls Among Older Adults: A Study in a US Medicare Population.

BACKGROUND: Approximately one-third of community-dwelling older adults fall each year, and approximately 10% have falls requiring medical services. Among other factors, research studies have linked certain medications with an increased risk of falls. OBJECTIVE: The aim of this study was to examine the risk of falls relative to use patterns among new and continuing falls-related drug (FRD) users. METHODS: A 10% random sample, insured in AARP® Medicare Supplement and AARP Medicare Part D Rx plans, was utilized to define new and continuing FRD users. New users had a 12-month pre-period without FRD use, whereas continuing users had at least one FRD in the pre-period. Both groups had 12-month follow-up after initiating or continuing FRD use. Characteristics associated with the risk of falls for new and continuing users were determined using multivariate logistic regression models. RESULTS: Among insureds, 44% used at least one of the FRD classes. Of these, 29% were new users (N = 35,340) and 71% were continuing users (N = 121,488). Fall rates for the two subgroups were similar at 7 and 8%, respectively. Characteristics associated with the risk of falls were previous injurious fall, use of two or more classes of FRDs, older age, poorer health, and being female. New users were at higher risk than continuing users. CONCLUSION: New users of FRDs were at highest risk of falls, and continuing users were at increased risk, especially with higher numbers of FRD classes. Both groups could benefit from falls awareness and prevention programs.

The Frequency and Health Benefits of Physical Activity for Older Adults.

The benefits of physical activity (PA) for older adults have been demonstrated in reduced prevalence of common chronic conditions, improved mental health, decreased cognitive decline, and reduced mortality rates. Less is understood concerning the health impacts of light-to-moderate intensity PA. The purpose of this study was to estimate light-to-moderate PA frequency levels-low (0-2 days/week), intermediate (3-4 days/week) and high (≥5 days/week)-among AARP Medicare Supplement insureds, identify characteristics, and estimate the association of PA levels with the prevalence of selected chronic conditions, health care utilization, and expenditures. In 2015, surveys were sent to a random sample of insureds. PA was determined from survey responses querying self-reported days per week of at least 30 minutes of light-to-moderate PA. Multivariate regression models, adjusting for confounding covariates and survey nonresponse bias, were utilized to determine the characteristics and association of intermediate and high PA levels with health outcomes. In a second analysis, results were stratified by age groups: 65-69, 70-79, and ≥80 years. Among survey respondents (n = 17,676), 23.3%, 33.9%, and 42.9% engaged in low, intermediate, and high PA, respectively. The strongest predictors of intermediate and high PA included being male, younger, self-reporting better health, using fewer prescription drugs, and being less likely to be diagnosed with common chronic conditions or depression. Those engaged in intermediate and high PA, overall and across age groups, had significantly lower health care utilization and expenditures and lower prevalence of most chronic conditions. Efforts to increase intermediate and high levels of PA among older adults should be encouraged.

Caregivers for older adults: Prevalence, characteristics, and health care utilization and expenditures.

The purpose of this study was to provide an overview of caregiver prevalence and characteristics and to estimate the impact of caregiving on health care utilization and expenditures among AARP® Medicare Supplement insureds to inform caregiver intervention strategies. A subgroup with live-in partners was used to investigate the additional effect of live-in health status on caregiver health. Multivariate regression models were utilized to determine caregivers' characteristics and associated impacts on their health care utilization and expenditures. Among respondents (n = 18,928), 14.9% self-identified as caregivers. The strongest characteristics included being younger, healthier, but reporting depression or loneliness. Caregivers of sicker live-ins were female, older and indicated moderate loneliness; caregivers of healthier live-ins were younger, healthier, but reported severe loneliness. Caregivers had significantly lower inpatient admissions and medical and prescription drug expenditures. These results indicated an adverse impact on psychological health associated with caregiving but no evidence of a negative impact on physical health.

The Impact of Personalized Preventive Care on Health Care Quality, Utilization, and Expenditures.

The objective of this study was to evaluate the impact on health care utilization and expenditure trends over time of a personalized preventive medicine program delivering individualized care focused on lifestyle behavior modification, disease prevention, and compliance with quality-related metrics. MD-Value in Prevention (MDVIP) is a network of affiliated primary care physicians who utilize a model of health care delivery based on an augmented physician-patient relationship and focused on personalized preventive health care. Multivariate modeling was used to control for demographics, socioeconomics, supply of health care services, and health status among 10,186 MDVIP members and randomly selected, matched nonmembers. Health care utilization and expenditure trends were tracked from the pre period prior to member enrollment for a period of up to 3 years post enrollment. MDVIP members experienced reduced utilization of emergency room and urgent care services compared to nonmembers. Program savings ranges indicated that, over time, increasing percentages of members achieved cost savings compared to nonmembers. Older age groups were more likely to realize savings in the early years with preventive activities indicating condition management, and younger age groups were most likely to achieve savings by the third year after enrollment. These results indicate that a primary care model based on an enhanced physician-patient relationship and focused on quality and personalized preventive care within a time frame of 3 years can achieve positive health care expenditure outcomes and improved health management.

The Impact of Obesity on Health Care Utilization and Expenditures in a Medicare Supplement Population.

Objective: Obesity is a contributor to increased chronic conditions resulting in higher utilization of medical services among broad populations of older adults. The objective of this study was to evaluate the magnitude of the impact of weight on health care use patterns among Medicare Supplement insureds. Method: We estimated the impact of weight as a function of body mass index (BMI) on health care utilization and expenditures using propensity weighted multivariate regression models. The outcomes were controlled initially for demographics and socioeconomics and then additionally for chronic conditions and health status. Results: Among the 9,484 survey respondents, 22.9% were obese. Those categorized as obese were significantly more likely to incur inpatient admissions and orthopedic procedures. Annualized health care expenditures were US$1,496 higher for obese compared with normal weight. The excess utilization and expenditures associated with obesity were explained by chronic conditions and poor health status. Conclusion: Obesity-related expenditures associated with medical management are largely preventable and may benefit from interventions that target lifestyle behaviors and weight management among older adults.

Disparities Among Those With Advance Directives in a Medicare Supplement Population.

Advance directives (ADs) detail patients' end-of-life (EOL) care preferences. We estimated AD prevalence rates among a Medicare Supplement population and determined characteristics associated with having ADs. We also estimated the impact of having an AD on EOL Medicare expenditures among respondents who later died. Survey respondents with an AD (72%) were significantly more likely to be female, older, nonminority, higher income and education, and have more comorbid conditions. Following regression adjustments, EOL expenditures were significantly lower for those with ADs in the last 3 months (-US$11 189) and 1 month (-US$6092) prior to death. Patients with ADs specifying their wishes for EOL care had significantly lower medical expenditures during the last few months of life. However, disparities exist among those with ADs that may warrant interventions.

Homebound older adults: Prevalence, characteristics, health care utilization and quality of care.

The purpose of this study was to estimate prevalence rates of homebound older adults, their characteristics and the impact of homebound status on health care utilization, expenditures and quality of medical care measures. Surveys were sent to new enrollees (n = 25,725) in AARP(®) Medicare Supplement plans (insured through UnitedHealthcare) to screen for serious chronic conditions, ambulatory disabilities and eligibility for care coordination programs. Health care utilization and expenditures were determined from paid claims. Member-level quality measures considered compliance with medication adherence and care patterns. Among survey respondents, 19.6% were classified as being homebound. The strongest predictors of being homebound included serious memory loss, being older, having more chronic conditions, taking more prescription medications and having multiple hospitalizations. Homebound had significantly higher health care utilization and expenditures. Homebound were more likely to be noncompliant with medication adherence and care pattern rules. Ongoing screening and subsequent interventions for new enrollees classified as homebound may be warranted.

Pharmaceutical Cost-Saving Strategies and their Association with Medication Adherence in a Medicare Supplement Population.

BACKGROUND: On average, Medicare Supplement insureds take about seven unique prescription medications each year, resulting in substantial out-of-pocket drug copayments, in addition to Medicare Supplement and Part D premiums. To help alleviate this financial burden, many individuals resort to cost-saving strategies that are not trackable by Part D insurance plans, likely resulting in an underestimation of medication adherence rates. OBJECTIVE: We aimed to estimate utilization rates of cost-saving strategies, measure member characteristics associated with these strategies and estimate if these strategies are associated with medication adherence. DESIGN: This was a cross-sectional analysis of a 2012-2013 survey of AARP® Medicare Supplement plan insureds with Part D pharmaceutical coverage. PARTICIPANTS: The study included 5,784 community-dwelling survey respondents ≥ 65 years of age, living in ten states and with self-reported use of prescription medications. MAIN MEASURES: Self-reported use of cost-saving strategies included: obtaining free samples from physicians, splitting pills so medications lasted longer, purchasing medications from other countries and/or over the internet, or purchasing medications through the Veterans Administration. Propensity weighted multivariate regressions were utilized to determine characteristics associated with the use of such strategies and the association with medication adherence as measured from Medicare Part D claims. KEY RESULTS: Among those taking medications, 39.6% used cost-saving strategies. Those using these strategies were significantly (p < 0.05) more likely to be male, non-minority, have more comorbid conditions, have more disabilities and use more medications. Few variables were significantly related to pharmaceutical nonadherence, but those who were nonadherent were significantly more likely to use more medications, split pills, obtain free samples from their physicians and be male. CONCLUSION: Cost-saving strategies are used extensively as a means to augment Medicare Part D coverage. These strategies are associated with measured medication nonadherence and likely result in underreporting of medication adherence rates. Pharmacy management programs should consider these additional medication sources in assisting plan members to problem solve cost-related medication management issues.

Obese older adults report high satisfaction and positive experiences with care.

BACKGROUND: Obese, older adults often have multiple chronic conditions resulting in multiple health care encounters. However, their satisfaction and experiences with care are not well understood. The objective of this study was to examine the independent impact of obesity on patient satisfaction and experiences with care in adults 65 years of age and older with Medigap insurance. METHODS: Surveys were mailed to 53,286 randomly chosen adults with an AARP® Medicare Supplement Insurance Plan insured by UnitedHealthcare Insurance Company (for New York residents, UnitedHealthcare Insurance Company of New York) in 10 states. Following adjustment for non-response bias, multivariate regression modeling was used to adjust for demographic, socioeconomic and health status differences to estimate the independent impact of weight on satisfaction and experiences with care. Outcome variables included four global and four composite measures of satisfaction and experiences with care. RESULTS: 21.4% of the respondents were obese. Relative to normal weight, obesity was significantly associated with higher patient satisfaction and better experiences with care in seven of the eight ratings measured. CONCLUSIONS: Obese individuals were more satisfied and had better experiences with care. Obese individuals had more office visits and discussions about nutrition, exercise and medical checks. This may have led to increased attentiveness to care, explaining the increase in satisfaction and better experiences with care. Given the high level of satisfaction and experiences with care in older, obese adults, opportunities exist for clinicians to address weight concerns in this population.

The cost burden of oral, oral pharyngeal, and salivary gland cancers in three groups: commercial insurance, Medicare, and Medicaid.

BACKGROUND: Head and neck cancers are of particular interest to health care providers, their patients, and those paying for health care services, because they have a high morbidity, they are extremely expensive to treat, and of the survivors only 48% return to work. Consequently the economic burden of oral cavity, oral pharyngeal, and salivary gland cancer (OC/OP/SG) must be understood. The cost of these cancers in the U.S. has not been investigated. METHODS: A retrospective analysis of administrative claims data for 6,812 OC/OP/SG cancer patients was undertaken. Total annual health care spending for OC/OP/SG cancer patients was compared to similar patients without OC/OP/SG cancer using propensity score matching for enrollees in commercial insurance, Medicare, and Medicaid. Indirect costs, as measured by short term disability days were compared for employed patients. RESULTS: Total annual health care spending for OC/OP/SG patients during the year after the index diagnosis was $79,151 for the Commercial population. Health care costs were higher for OC/OP/SG cancer patients with Commercial Insurance ($71,732, n = 3,918), Medicare ($35,890, n = 2,303) and Medicaid ($44,541, n = 585) than the comparison group (all p < 0.01). Commercially-insured employees with cancer (n = 281) had 44.9 more short-term disability days than comparison employees (p < 0.01). Multimodality treatment was twice the cost of single modality therapy. Those patients receiving all three treatments (surgery, radiation, and chemotherapy) had the highest costs of cost of care, from $96,520 in the Medicare population to $153,892 in the Commercial population. CONCLUSIONS: In the U.S., the cost of OC/OP/SG cancer is significant and may be the most costly cancer to treat in the U.S. The results of this analysis provide useful information to health care providers and decision makers in understanding the economic burden of head and neck cancer. Additionally, this cost information will greatly assist in determining the cost-effectiveness of new technologies and early detection systems. Earlier identification of cancers by patients and providers may potentially decrease health care costs, morbidity and mortality.

The economic value of specialized lower-extremity medical care by podiatric physicians in the treatment of diabetic foot ulcers.

BACKGROUND: We sought to examine the economic value of specialized lower-extremity medical care by podiatric physicians in the treatment of diabetic foot ulcers by evaluating cost outcomes for patients with diabetic foot ulcer who did and did not receive care from a podiatric physician in the year before the onset of a foot ulcer. METHODS: We analyzed the economic value among commercially insured patients and Medicare-eligible patients with employer-sponsored supplemental medical benefits using the MarketScan Databases. The analysis consisted of two parts. In part I, we examined cost or savings per patient associated with care by podiatric physicians using propensity score matching and regression techniques; in part II, we extrapolated cost or savings to populations. RESULTS: Matched and regression-adjusted results indicated that patients who visited a podiatric physician had $13,474 lower costs in commercial plans and $3,624 lower costs in Medicare plans during 2-year follow-up (P < .01 for both). A positive net present value of increasing the share of patients at risk for diabetic foot ulcer by 1% was found, with a range of $1.2 to $17.7 million for employer-sponsored plans and $1.0 to $12.7 million for Medicare plans. CONCLUSIONS: These findings suggest that podiatric medical care can reduce the disease and economic burdens of diabetes.

The relationship between health risks and health and productivity costs among employees at Pepsi Bottling Group.

OBJECTIVE: To evaluate relationships between modifiable health risks and costs and measure potential cost savings from risk reduction programs. METHODS: Health risk information from active Pepsi Bottling Group employees who completed health risk assessments between 2004 and 2006 (N = 11,217) were linked to medical care, workers' compensation, and short-term disability cost data. Ten health risks were examined. Multivariate analyses were performed to estimate costs associated with having high risk, holding demographics, and other risks constant. Potential savings from risk reduction were estimated. RESULTS: High risk for weight, blood pressure, glucose, and cholesterol had the greatest impact on total costs. A one-percentage point annual reduction in the health risks assessed would yield annual per capita savings of $83.02 to $103.39. CONCLUSIONS: Targeted programs that address modifiable health risks are expected to produce substantial cost reductions in multiple benefit categories.

Effects of naltrexone treatment for alcohol-related disorders on healthcare costs in an insured population.

OBJECTIVE: To determine the impact of treatment with oral naltrexone on healthcare costs in patients with alcohol-related disorders. METHODS: Using data from the MarketScan Commercial Claims and Encounters Database for 2000-2004, we identified a naltrexone group (with an alcohol-related diagnosis and at least one pharmacy claim for oral naltrexone) and two control groups. Alcohol controls had an alcohol-related diagnosis and were not prescribed an alcoholism treatment medication. Nonalcohol controls had no alcohol-related diagnosis and no prescription for an alcoholism treatment medication. The control groups were matched three to one to the naltrexone group on demographic and other relevant measures. Healthcare expenditures were calculated for the 6-month periods before and after the index naltrexone drug claim (or matched date for controls). Univariate and multivariate analyses were used to compare the groups on key characteristics and on healthcare costs. RESULTS: Naltrexone patients (n = 1,138; 62% men; mean age 45 +/- 11 years) had significantly higher total healthcare expenditures in the pre-index period than either of the control groups. In the postindex period, naltrexone patients had a significantly smaller increase than alcohol controls in total alcohol-related expenditures. Total nonalcohol-related expenditures also increased significantly less for the naltrexone group than for the alcohol control group. Multivariate analyses showed that naltrexone treatment significantly reduced alcohol-related, nonalcohol-related, and total healthcare costs relative to alcohol controls. CONCLUSIONS: Although prior to treatment patients with alcohol-related disorders had higher healthcare costs, treatment with oral naltrexone was associated with reductions both in alcohol-related and nonalcohol-related healthcare costs.

The relationship between modifiable health risk factors and medical expenditures, absenteeism, short-term disability, and presenteeism among employees at novartis.

OBJECTIVE: To quantify the impact of health risks on medical care and productivity costs in an employed population. METHODS: Health risk, medical care, and productivity data were obtained for 5875 Novartis employees in 2005-2006. Factor analysis was performed to identify relationships among health risks. Multiple regression analyses were applied to estimate relationships between combined risk factors and costs. RESULTS: We found a significant and consistent association among three factors (high biometric laboratory values, cigarette and alcohol use, and poor emotional health) and increased presenteeism for both men and women and increased absenteeism for women. Medical care expenditures were 13-22% higher for men and women at risk for the high biometric laboratory values and the emotional health factor. CONCLUSIONS: There is a potential for medical and productivity savings for employers able to reduce health risks among their workers.
