Using Targeted mHealth Messages to Address Hypertension and Diabetes Self-Management in Cambodia: Protocol for a Clustered Randomized Controlled Trial.

BACKGROUND: Hypertension and diabetes represent the first and third highest contributors to global disability. While mobile health (mHealth) messaging programs have rapidly increased in low- and middle-income countries (LMIC), adaptations for specific patient health needs is a new approach to manage chronic conditions. OBJECTIVE: The primary aim of this study is to develop and test an mHealth communication intervention using electronic data capture (by tablet) and voice messaging to improve hypertension and diabetes self-management in Cambodia. The secondary aim is to share results with the Cambodian Ministry of Health and development partners to inform health policy and develop strategies for hypertension and diabetes control. METHODS: The study design is a cluster randomized controlled clinical trial randomizing each of 75 Community peer educators (PEs), trained and coordinated by MoPoTsyo Patient Information Center in Phnom Penh, into one of 3 groups of 25 (approximately 60 patients each) to receive either tablet+messages, tablet only, or no intervention (control). The total sample within each group includes 25 clusters and approximately 1500 patients located in 7 Operational Districts in rural regions or urban slums in Cambodia. The interventions (groups 1 and 2) were compared with usual PE monitoring without the tablet or mHealth messaging interventions. Focus groups and informant interviews were conducted to develop messages according to specific themes-medications adherence, laboratory testing, physician visits, obesity, smoking, and general lifestyle issues. Using the data received at monthly PE monitoring meetings, patients will receive specific messages based on their individual health challenges. Following the intervention completion, clinical and process outcomes will be compared with baseline metrics between groups. RESULTS: PEs were randomized in July 2017, and the intervention was implemented in September 2017 through June 2018. Analyses are underway. CONCLUSIONS: This project is unique in its combination of electronic data transfer, which can be accessed immediately, with voice messages most relevant to individual patients' needs. Positive results will indicate the value of using targeted messaging in patient-specific, self-management issues to improve hypertension and diabetes control.

Barriers and facilitators to treatment among patients with newly diagnosed hypertension in Nepal.

OBJECTIVE: Hypertension is a significant and rising burden in Nepal. The disease remains undetected and inadequately managed. However, no studies have been conducted to understand the inhibiting and facilitating factors to hypertension treatment among newly diagnosed cases. This qualitative study aimed to explore barriers and facilitators to treatment among patients with newly diagnosed hypertension aged ≥18 years in Dhulikhel, Nepal. METHODS: We conducted seven focus group discussions with 35 patients with newly diagnosed hypertension identified through community surveillance of the Dhulikhel Heart Study, an observational cohort of Dhulikhel Hospital, Kathmandu University. Audiotaped discussions were transcribed, inductively coded and analysed by the thematic framework method using Atlas.ti V.7. RESULTS: Hypertension was viewed as a rising problem in the community. Participants had limited knowledge and many misbeliefs regarding hypertension and its treatment. The major barriers included absence of symptoms, reluctance to take medicine, low perceived seriousness of the disease, challenges in behaviour change (diet and exercise), lack of family support, and lack of communication and trust with the provider. The major reported facilitating factors were fear of consequences of the disease, and family support in controlling diet and adhering to treatment. CONCLUSIONS: A number of factors emerged as barriers and facilitators to hypertension treatment. This information can be useful in designing appropriate health interventions to improve hypertension management.

Barriers and facilitators of diabetes services in Nepal: a qualitative evaluation.

For the past three decades, the burden of diabetes in Nepal has been steadily increasing, with an estimated 3% annual increase since the year 2000. Although the burden is increasing, the methods of addressing the challenge have remained largely unchanged. This study sought to assess the current state of diabetes services provided by health facilities and to identify the major barriers that people with diabetes commonly face in Nepal. For this qualitative study, we selected five health facilities of varying levels and locations. At each site, we employed three unique methods: a process evaluation of the diabetes treatment and prevention services available, in-depth interviews with patients and focus group discussions with community members without diabetes. We used thematic analysis to analyse the data. Our findings were organized into the five categories of the Ecological Model: Individual, Interpersonal, Organizational, Community and Public Policy. Sub-optimal knowledge and behaviors of patients often contributed to poor diabetes management, especially related to diet control, physical activity and initiation of drug treatment. Social support was often lacking. Organizational challenges included health provider shortages, long wait times, high patient loads and minimal time available to spend with patients, often resulting in incomprehensive care. Public policy challenges include limited services in rural settings and financial burden. The scarcity of financial and human resources for health in Nepal often results in the inability of the current healthcare system to provide comprehensive prevention and management services for chronic diseases. A multilevel, coordinated approach is necessary to address these concerns. In the short-term, adding community-based supplementary solutions outside of the traditional hospital-based model could help to increase access to affordable services.

The association of estimated salt intake with blood pressure in a Viet Nam national survey.

OBJECTIVE: To evaluate the association of salt consumption with blood pressure in Viet Nam, a developing country with a high level of salt consumption. DESIGN AND SETTING: Analysis of a nationally representative sample of Vietnamese adults 25-65 years of age who were surveyed using the World Health Organization STEPwise approach to Surveillance protocol. Participants who reported acute illness, pregnancy, or current use of antihypertensive medications were excluded. Daily salt consumption was estimated from fasting mid-morning spot urine samples. Associations of salt consumption with systolic blood pressure and prevalent hypertension were assessed using adjusted linear and generalized linear models. Interaction terms were tested to assess differences by age, smoking, alcohol consumption, and rural/urban status. RESULTS: The analysis included 2,333 participants (mean age: 37 years, 46% male, 33% urban). The average estimated salt consumption was 10g/day. No associations of salt consumption with blood pressure or prevalent hypertension were observed at a national scale in men or women. The associations did not differ in subgroups defined by age, smoking, or alcohol consumption; however, associations differed between urban and rural participants (p-value for interaction of urban/rural status with salt consumption, p = 0.02), suggesting that higher salt consumption may be associated with higher systolic blood pressure in urban residents but lower systolic blood pressure in rural residents. CONCLUSIONS: Although there was no evidence of an association at a national level, associations of salt consumption with blood pressure differed between urban and rural residents in Viet Nam. The reasons for this differential association are not clear, and given the large rate of rural to urban migration experienced in Viet Nam, this topic warrants further investigation.

Awareness, treatment and control of hypertension in Nepal: findings from the Dhulikhel Heart Study.

OBJECTIVES: Although previous studies have suggested alarming rise in the prevalence of hypertension in Nepal, there is dearth of information on its awareness, treatment and control. In this cross-sectional study, we assessed awareness, treatment and control of hypertension among 298 hypertensive adults from the suburban town of Dhulikhel, Nepal. METHODS: This cross-sectional study is based on Dhulikhel Heart Study, which included 1073 adults, aged ≥18 years, recruited from randomly selected households. Comprehensive health interviews and blood pressure measurements were completed during home interviews. Hypertensives (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or receiving antihypertensive medication) were further evaluated for awareness, treatment and control of hypertension. Multivariate regression model quantified the association of the sociodemographic characteristics and the cardiovascular disease (CVD) risk factors with hypertension awareness. Differences between sociodemographic characteristics and CVD risk factors with treatment and control of hypertension were tested using χ2 tests. RESULTS: A total of 43.6% of all hypertensives (n=298) were aware of their hypertension status. In multivariate analyses, hypertension awareness was associated with increasing age (p<0.001). More than three-fourth (76.1%) of those who were aware of their hypertension status (n=130) were currently on treatment. There were significant differences in treatment status by sex, occupation, age, income quartiles and body mass index. Only 35.3% of those on treatment (n=99) had blood pressure control. CONCLUSIONS: The levels of awareness, treatment and control of hypertension in this sample of Nepalese adults were low.

Bolstering medical education to enhance critical care capacity in Cambodia.

The capacity to care for the critically ill has long been viewed as a fundamental element of established and comprehensive health care systems. Extending this capacity to health care systems in low- and middle-income countries is important given the burden of disease in these regions and the significance of critical care in overall health system strengthening. However, many practicalities of improving access and delivery of critical care in resource-limited settings have yet to be elucidated. We have initiated a program to build capacity for the care of critically ill patients in one low-income Southeast Asian country, Cambodia. We are leveraging existing international academic partnerships to enhance postgraduate critical care education in Cambodia. After conducting a needs assessment and literature review, we developed a three-step initiative targeting training in mechanical ventilation. First, we assessed and revised the current resident curriculum pertaining to mechanical ventilation. We addressed gaps in training, incorporated specific goals and learning objectives, and decreased the hours of lectures in favor of additional bedside training. Second, we are incorporating e-learning, e-teaching, and e-assessment into the curriculum, with both live, interactive and independent, self-paced online instruction. Third, we are developing a train-the-trainer program defined by bidirectional international faculty exchanges to provide hands-on, case-based, and bedside training to achieve competency-based outcomes. In targeting specific educational needs and a key population-the next generation of Cambodian intensivists-this carefully designed approach should address some existing gaps in the health care system and hopefully yield a lasting impact.

Appropriate body mass index and waist circumference cutoff for overweight and central obesity among adults in Cambodia.

BACKGROUND: Body mass index (BMI) and waist circumference (WC) are used in risk assessment for the development of non-communicable diseases (NCDs) worldwide. Within a Cambodian population, this study aimed to identify an appropriate BMI and WC cutoff to capture those individuals that are overweight and have an elevated risk of vascular disease. METHODOLOGY/PRINCIPAL FINDINGS: We used nationally representative cross-sectional data from the STEP survey conducted by the Department of Preventive Medicine, Ministry of Health, Cambodia in 2010. In total, 5,015 subjects between age 25 and 64 years were included in the analyses. Chi-square, Fisher's Exact test and Student t-test, and multiple logistic regression were performed. Of total, 35.6% (n = 1,786) were men, and 64.4% (n = 3,229) were women. Mean age was 43.0 years (SD = 11.2 years) and 43.6 years (SD = 10.9 years) for men and women, respectively. Significant association of subjects with hypertension and hypercholesterolemia was found in those with BMI ≥ 23.0 kg/m(2) and with WC >80.0 cm in both sexes. The Area Under the Curve (AUC) from Receiver Operating Characteristic curves was significantly greater in both sexes (all p-values <0.001) when BMI of 23.0 kg/m(2) was used as the cutoff point for overweight compared to that using WHO BMI classification for overweight (BMI ≥ 25.0 kg/m(2)) for detecting the three cardiovascular risk factors. Similarly, AUC was also significantly higher in men (p-value <0.001) when using WC of 80.0 cm as the cutoff point for central obesity compared to that recommended by WHO (WC ≥ 94.0 cm in men). CONCLUSION: Lower cutoffs for BMI and WC should be used to identify of risks of hypertension, diabetes, and hypercholesterolemia for Cambodian aged between 25 and 64 years.

The prevalence and associated factors for prehypertension and hypertension in Cambodia.

BACKGROUND: Hypertension is strongly associated with adverse cardiovascular outcomes and was the leading modifiable associated factor for global disease burden in 2010. Analysis of modifiable associated factors will be important to those concerned with mitigating the adverse effects of hypertension. We studied factors associated with hypertension in adults aged 25-64 years of age in Cambodia in order to help develop strategies for planned new initiatives for prevention and control of hypertension. METHODS: Using data from a nationwide survey in Cambodia assessing the prevalence of associated factors for non-communicable disease in 2010 (WHO STEPs survey), 5017 participants between the ages of 25 and 64 years were included in a secondary analysis of the prevalence and predictors of hypertension. RESULTS: The prevalence of prehypertension in this sample was approximately double that of overall hypertension (27.9% vs 15.3%). Male sex, increasing age and known cardiovascular associated factors, including higher Body Mass Index (BMI), dyslipidaemia, impaired fasting glycaemia, and abdominal obesity were all associated with an increased prevalence of hypertension. In multivariate models, increasing age was the strongest associated factor for hypertension (OR 8.79, 95% CI (5.43 to 14.2)), whereas, higher BMI was the primary associated factor associated with prehypertension (OR 3.27, 95% CI 2.21 to 4.82). CONCLUSIONS: Modifiable cardiovascular-associated factors are strongly correlated with prehypertension and hypertension in Cambodia, and may be a focus of public health and primary care strategies to mitigate subsequent ischaemic heart disease and stroke. A national strategy aimed at increased screening and adherence to medical therapy is a necessary first step to reduce burden of disease and related morbidities.

Adherence to guideline-directed venous thromboembolism prophylaxis among medical and surgical inpatients at 33 academic medical centers in the United States.

This study's purpose was to describe compliance with established venous thromboembolism (VTE) prophylaxis guidelines in medical and surgical inpatients at US academic medical centers (AMCs). Data were collected for a 2007 University HealthSystem Consortium Deep Vein Thrombosis/Pulmonary Embolism (DVT/PE) Benchmarking Project that explored VTE in AMCs. Prophylaxis was considered appropriate based on 2004 American College of Chest Physicians guidelines. A total of 33 AMCs from 30 states participated. In all, 48% of patients received guideline-directed prophylaxis-59% were medical and 41% were surgical patients. VTE history was more common among medical patients with guideline-directed prophylaxis. Surgical patients admitted from the emergency department and with higher illness severity were more likely to receive appropriate prophylaxis. Despite guidelines, VTE prophylaxis remains underutilized in these US AMCs, particularly among surgical patients. Because AMCs provide the majority of physician training and should reflect and set care standards, this appears to be an opportunity for practice and quality improvement and for education.

Translating a multifactorial fall prevention intervention into practice: a controlled evaluation of a fall prevention clinic.

Although multifactorial fall prevention interventions have been shown to reduce falls and injurious falls, their translation into clinical settings has been limited. This article describes a hospital-based fall prevention clinic established to increase availability of preventive care for falls. Outcomes for 43 adults aged 65 and older seen during the clinic's first 6 months of operation were compared with outcomes for 86 age-, sex-, and race-matched controls; all persons included in analyses received primary care at the hospital's geriatrics clinic. Nonsignificant differences in falls, injurious falls, and fall-related healthcare use according to study group in multivariate adjusted models were observed, probably because of the small, fixed sample size. The percentage experiencing any injurious falls during the follow-up period was comparable for fall clinic visitors and controls (14% vs 13%), despite a dramatic difference at baseline (42% of clinic visitors vs 15% of controls). Fall-related healthcare use was higher for clinic visitors during the baseline period (21%, vs 12% for controls) and decreased slightly (to 19%) during follow-up; differences in fall-related healthcare use according to study group from baseline to follow-up were nonsignificant. These findings, although preliminary because of the small sample size and the baseline difference between the groups in fall rates, suggest that being seen in a fall prevention clinic may reduce injurious falls. Additional studies will be necessary to conclusively determine the effects of multifactorial fall risk assessment and management delivered by midlevel providers working in real-world clinical practice settings on key outcomes, including injurious falls, downstream fall-related healthcare use, and costs.

Health care costs and participation in a community-based health promotion program for older adults.

INTRODUCTION: EnhanceWellness (EW) is a community-based health promotion program that helps prevent disabilities and improves health and functioning in older adults. A previous randomized controlled trial demonstrated a decrease in inpatient use for EW participants but did not evaluate health care costs. We assessed the effect of EW participation on health care costs. METHODS: We performed a retrospective cohort study in King County, Washington. Enrollees in Group Health Cooperative (GHC), a mixed-model health maintenance organization, who were aged 65 years or older and who participated in EW from 1998 through 2005 were matched 1:3 by age and sex to GHC enrollees who did not participate in EW. We matched 218 EW participants by age and sex to 654 nonparticipants. Participants were evaluated for 1 year after the date they began the program. The primary outcome was total health care costs; secondary outcomes were inpatient costs, primary care costs, percentage of hospitalizations, and number of hospital days. We compared postintervention outcomes between EW participants and nonparticipants by using linear regression. Results were adjusted for prior year costs (or health care use), comorbidity, and preventive health care-seeking behaviors. RESULTS: Mean age of participants and nonparticipants was 79 years, and 72% of participants and nonparticipants were female. Adjusted total costs in the year following the index date were $582 lower among EW participants than nonparticipants, but this difference was not significant. CONCLUSION: Although EW participation demonstrated health benefits, participation does not appear to result in significant health care cost savings among people receiving health care through a health maintenance organization.

Promoting sustainable community change in support of older adult physical activity: evaluation findings from the Southeast Seattle Senior Physical Activity Network (SESPAN).

Researchers have identified as effective and worthy of broader dissemination a variety of intervention strategies to promote physical activity among older adults. This paper reports results of a community-organizing approach to disseminating evidence-based interventions in a sustainable way: The Southeast Seattle Senior Physical Activity Network (SESPAN). SESPAN was implemented in Southeast Seattle, a group of multicultural neighborhoods extending 8 miles southeast of downtown Seattle, with a population of 56,469 in 2000, with 12% (7,041) aged 65 and older. The SESPAN organizing strategy involved networking to: (1) make connections between two or more community organizations to create new senior physical activity programs; and (2) build coalitions of community groups and organizations to assist in making larger scale environmental and policy changes to increase senior physical activity. The SESPAN evaluation used an uncontrolled prospective design focusing on sustainable community changes, including new or modified programs, policies, and practices. Networking among organizations led to the creation of 16 ongoing exercise classes and walking groups, serving approximately 200 older adults in previously underserved Southeast Seattle communities. In addition, the project's health coalition is sustaining current activities and generating new programs and environmental changes. The success of the SESPAN organizing model depended on identifying and involving champions in partner organizations who provided support and resources for implementing programs.

A community-organizing approach to promoting physical activity in older adults: the southeast senior physical activity network.

This article describes a community organizing approach to promoting physical activity among underserved older adults in southeast Seattle: the Southeast Senior Physical Activity Network (SESPAN). The organizing strategy involves networking with a variety of community-based organizations, with two broad objectives: (a) program objective-to make connections between two (or more) community-based organizations to create senior physical activity programs where none existed before; and (b) coalition objective-to build a broader network or coalition of groups and organizations to assist in making larger scale environmental and policy changes. Networking among organizations led to the creation of a number of potentially sustainable walking and exercise programs that are reaching previously underserved communities within Southeast Seattle. In addition, a major community event led to the establishment of a health coalition that has the potential to continue to generate new broad-based programs and larger scale environmental changes.

Initial test of the seattle asthma severity and control questionnaire: a multidimensional assessment of asthma severity and control.

BACKGROUND: The Seattle Asthma Severity and Control Questionnaire (SASCQ) was designed as a short, sensitive, and quantitative measure of asthma severity, impairment, and risk. OBJECTIVES: To evaluate the distribution of responses to the SASCQ in a diverse asthma population and to determine whether the questionnaire is associated with other measures of asthma severity and control. METHODS: A cross-sectional study of 188 asthmatic patients was conducted in a large academic primary care network. Asthma severity was confirmed in a subgroup of 44 patients by means of an in-person interview and lung function measurement. RESULTS: The SASCQ score had a nearly normal distribution across the heterogeneous population and less of a floor effect than the number of asthma-free days. The SASCQ score showed a higher symptom burden in the mildest asthmatic patients compared with nonasthmatic controls. Asthma severity evaluated using the questionnaire was correlated with asthma severity evaluated by means of in-person interview and with controller medication class. The SASCQ score was associated with primary care visits for asthma, emergency department treatment for asthma, days missed from work, and confidence to control asthma symptoms; the associations between these measures of impairment and risk were all stronger for the SASCQ score than for asthma-free days. CONCLUSIONS: The SASCQ is a quantitative measure of asthma that accurately discriminates between established levels of asthma severity and that is associated with other measures of asthma control and risk.

Secondary prevention of myocardial infarction with nonpharmacologic strategies in a Medicaid cohort.

BACKGROUND: The quality of health care after myocardial infarction (MI) may be lacking; in particular, guidelines for nonpharmacologic interventions (cardiac rehabilitation, smoking cessation) may receive insufficient priority. We identified gaps between secondary prevention guidelines and ambulatory care received by Medicaid enrollees after an MI. METHODS: MI survivors were selected by using 2004 Washington State Medicaid administrative claims. Deidentified data were abstracted for hospitalizations, ambulatory care, and prescriptions for 365 days after the MI. Cox regression analysis compared utilization of guideline-directed secondary prevention strategies with death and recurrent hospitalization. RESULTS: The sample size was 372. Fifty patients died during the year after the MI, and 144 were rehospitalized. Only 2 patients attended a cardiac rehabilitation program. Tobacco cessation counseling was associated with a 66% reduction in death, but only 72.6% of smokers were counseled. Less than half (45.4%) of patients saw a primary care provider within 90 days of their MI, and 7.5% never contacted a health care provider. Receiving regular primary care was associated with a decreased risk for death (hazard ratio, 0.91; 95% confidence interval, 0.84-0.97, P < .01). A protective trend was associated with care by a cardiologist, but only 21.5% received specialist care. CONCLUSION: Analysis of Medicaid claims data suggests rates of secondary prevention are less than optimal. To improve survival and reduce rehospitalization after an MI, policy changes (tobacco cessation benefits, expansion of rehabilitation programs), health care capacity (training, referral patterns, and coordination of care), and improvements to access (removing barriers, increasing facilities, targeting minority populations) could be implemented.

A comparison of how generalists and fellowship-trained geriatricians provide "geriatric" care.

OBJECTIVES: To determine whether outpatient care provided to older patients by fellowship-trained geriatricians is distinguishable from that provided by generalists. DESIGN: Observational study. SETTING: Three primary care clinics of an academic medical center. PARTICIPANTS: Random sample of 140 adults aged 65 and older receiving primary care at one of the clinics. MEASUREMENTS: A medical chart review involving records of 69 patients receiving primary care from a fellowship-trained geriatrician and 71 patients receiving primary care from a generalist (general internal medicine or family practice) was conducted; information pertaining to two practice behaviors relevant to the care of older adults--avoidance of inappropriate prescribing and proactive assessments for geriatric syndromes--was abstracted. RESULTS: Geriatricians scored 17.6 out of a possible 24 points, on average; generalists scored 14.2 (P<.001). Geriatricians scored higher than generalists on prescribing and geriatric syndrome assessments. In a linear regression model adjusting for patient age and number of comorbidities and clustering according to provider, provider specialty was strongly associated with overall score (beta coefficient for specialty=6.75, P<.001; 95% confidence interval=4.57-8.94). CONCLUSION: The practice style of fellowship-trained geriatricians caring for older adults appears to differ from that of generalists with regard to prescribing behavior and assessment for geriatric syndromes.

Healthcare cost differences with participation in a community-based group physical activity benefit for medicare managed care health plan members.

OBJECTIVES: To determine whether participation in a physical activity benefit by Medicare managed care enrollees is associated with lower healthcare utilization and costs. DESIGN: Retrospective cohort study. SETTING: Medicare managed care. PARTICIPANTS: A cohort of 1,188 older adult health maintenance organization enrollees who participated at least once in the EnhanceFitness (EF) physical activity benefit and a matched group of enrollees who never used the program. MEASUREMENTS: Healthcare costs and utilization were estimated. Ordinary least squares regression was used, adjusting for demographics, comorbidity, indicators of preventive service use, and baseline utilization or cost. Robustness of findings was tested in sensitivity analyses involving continuous propensity score adjustment and generalized linear models with nonconstant variance assumptions. RESULTS: EF participants had similar total healthcare costs during Year 1 of the program, but during Year 2, adjusted total costs were $1,186 lower (P=.005) than for non-EF users. Differences were partially attributable to lower inpatient costs (-$3,384; P=.02), which did not result from high-cost outliers. Enrollees who attended EF an average of one visit or more per week had lower adjusted total healthcare costs in Year 1 (-$1,929; P<.001) and Year 2 (-$1,784; P<.001) than nonusers. CONCLUSION: Health plan coverage of a preventive physical activity benefit for seniors is a promising strategy to avoid significant healthcare costs in the short term.

Depression and use of a health plan-sponsored physical activity program by older adults.

BACKGROUND: The purpose of this study was to determine the associations between depression and the likelihood of enrollment in a health plan-sponsored physical activity program and pattern of program participation over 2 years; a secondary aim was to examine the association between participation dose and depression risk. There are no published studies on how depression influences participation in health plan-sponsored physical activity programs and how participation affects depression risk in older adults in nonresearch settings. METHODS: This study used administrative data from a Medicare Advantage plan. Participants (n=4766) were enrolled in the plan for at least 1 year prior to participating in the plan-sponsored health club benefit (Silver Sneakers). Controls were age- and gender-matched to participants (n=9035). Members were identified as having depression based on ICD-9-CM codes. Multivariate regression and generalized estimating equations models were used. Data were collected between 1998 and 2003 and analyzed in 2008. RESULTS: Members who had a history of depression were as likely to participate in Silver Sneakers as nondepressed members (OR: 1.03; 95% CI=0.89, 1.20; p=0.67). The risk of lapse in Silver Sneakers attendance was 28%-55% (p<0.05) higher for depressed participants during months 15-24. For nondepressed Silver Sneakers participants, attendance of at least 2 visits/week during Year 1 was significantly associated with lower risk of depression in Year 2 (OR=0.54; 95% CI=0.37, 0.79; p=0.002); a similar but statistically nonsignificant association was observed for previously depressed participants (OR=0.51; 95% CI=0.26, 1.02; p=0.06). CONCLUSIONS: While depressed older adults are as likely to enroll in a health plan-sponsored physical activity as nondepressed members, they were at higher risk of attendance lapses. Greater participation in the physical activity program was associated with lower depression risk.

Health care use and costs associated with use of a health club membership benefit in older adults with diabetes.

OBJECTIVE: The purpose of this study was to determine whether elective use of a health plan-sponsored health club membership had an impact on health care use and costs among older adults with diabetes. RESEARCH DESIGN AND METHODS: Administrative claims for 2,031 older adults with diabetes enrolled in a Medicare Advantage plan were obtained for this retrospective cohort study. Participants (n = 618) in the plan-sponsored health club benefit (Silver Sneakers [SS]) and control subjects (n = 1,413) matched on SS enrollment index date were enrolled in the plan for at least 1 year before the index date. Two-year health care use and costs of SS participants and control subjects were estimated in regressions adjusting for baseline differences. RESULTS: SS participants were more likely to be male, had a lower chronic disease burden, used more preventive services, and had a lower prevalence of arthritis (P or=2 SS visits/week in year 1 had lower total costs in year 2 ($2,141 [-$3,877 to -$405], P = 0.02) than participants who made <2 visits/week. CONCLUSIONS: Use of a health club benefit by older adults with diabetes was associated with slower growth in total health care costs over 2 years; greater use of the benefit was actually associated with declines in total costs.

Managed-Medicare health club benefit and reduced health care costs among older adults.

INTRODUCTION: Our study was undertaken to determine the association between use of a health plan-sponsored health club benefit by older adults and total health care costs over 2 years. METHODS: This retrospective cohort study used administrative and claims data from a Medicare Advantage plan. Participants (n = 4766) were enrolled in the plan for at least 1 year before participating in the plan-sponsored health club benefit (Silver Sneakers). Controls (n = 9035) were matched to participants by age and sex according to the index date of Silver Sneakers enrollment. Multivariate regression models were used to estimate health care use and costs and to make subgroup comparisons according to frequency of health club visits. RESULTS: Compared with controls, Silver Sneakers participants were older and more likely to be male, used more preventive services, and had higher total health care costs at baseline. Adjusted total health care costs for Silver Sneakers participants and controls did not differ significantly in year 1. By year 2, compared with controls, Silver Sneakers participants had significantly fewer inpatient admissions (-2.3%, 95% confidence interval, -3.3% to -1.2%; P < .001) and lower total health care costs (-$500; 95% confidence interval, -$892 to -$106; P = .01]. Silver Sneakers participants who averaged at least two health club visits per week over 2 years incurred at least $1252 (95% confidence interval, -$1937 to -$567; P < .001) less in health care costs in year 2 than did those who visited on average less than once per week. CONCLUSION: Regular use of a health club benefit was associated with slower growth in total health care costs in the long term but not in the short term. These findings warrant additional prospective investigations to determine whether policies to offer health club benefits and promote physical activity among older adults can reduce increases in health care costs.
