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.

Background The burden of non-communicable diseases (NCDs) is increasing in low- and middle-income countries (LMICs) where NCDs cause 4:5 deaths, disproportionately affect poorer populations, and carry a large economic burden. Digital interventions can improve NCD management for these hard-to-reach populations with inadequate health systems and high cell-phone coverage; however, there is limited research on whether digital health is reaching this potential. We conducted a process evaluation to understand challenges and successes from a digital health intervention trial to support Cambodians living with NCDs in a peer educator (PE) program. Methods MoPoTsyo, a Cambodian non-governmental organization (NGO), trains people living with diabetes and/or hypertension as PEs to provide self-management education, support, and healthcare linkages for better care management among underserved populations. We partnered with MoPoTsyo and InSTEDD in 2016-2018 to test tailored and targeted mHealth mobile voice messages and eHealth tablets to facilitate NCD management and clinical-community linkages. This cluster randomized controlled trial (RCT) engaged 3,948 people and 75 PEs across rural and urban areas. Our mixed methods process evaluation was guided by RE-AIM to understand impact and real-world implications of digital health. Data included patient (20) and PE interviews (6), meeting notes, and administrative datasets. We triangulated and analyzed data using thematic analysis, and descriptive and complier average causal effects statistics (CACE). Results Reach: intervention participants were more urban (66% vs. 44%), had more PE visits (39 vs. 29), and lower uncontrolled hypertension [12% and 7% vs. 23% and 16% uncontrolled systolic blood pressure (SBP) and diastolic blood pressure (DBP)]. Adoption: patients were sent mean [standard deviation (SD)] 30 [14] and received 14 [8] messages; 40% received no messages due to frequent phone number changes. Effectiveness: CACE found clinically but not statistically significant improvements in blood pressure and sugar for mHealth participants who received at least one message vs. no messages. Implementation: main barriers were limited cellular access and that mHealth/eHealth could not solve structural barriers to NCD control faced by people in poverty. Maintenance: had the intervention been universally effective, it could be paid for from additional revolving drug fund revenue, new agreements with mobile networks, or the government. Conclusions Evidence for digital health to improve NCD outcomes in LMICs are limited. This study suggests digital health alone is insufficient in countries with low resource health systems and that high cell phone coverage did not translate to access. Adding digital health to an NCD peer network may not significantly benefit an already effective program; mHealth may be better for hard-to-reach populations not connected to other supports. As long as mHealth remains an individual-level intervention, it will not address social determinants of health that drive outcomes. Future digital health research and practice to improve NCD management in LMICs requires engaging government, NGOs, and technology providers to work together to address barriers.

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.

BackgroundSubstantial evidence supports the effectiveness of peer educator programs for diabetes management in low- and middle-income countries. However, little is known about peer educators' impact relative to other treatment components such as medication and physician consultation. In Cambodia, the non-governmental organization MoPoTsyo organizes four services for people with diabetes: self-management training through peer educator visits, lab tests, physician consultations, and low-cost medicines. Our aims were to 1) quantify MoPoTsyo participant utilization of each program service and 2) define the relationship between each program service and glycemic control.MethodsWe conducted a retrospective cohort study among 4,210 MoPoTsyo participants, using data collected by MoPoTsyo from 2006-2016. Independent variables assessed were medication adherence, number of peer educator visits, number of physician consultations, and number of lab tests. A multiple logistic regression model was used to evaluate the association between these disease management services and glycemic control-fasting plasma glucose ≤130 mg/dl or post-prandial glucose ≤180 mg/dl-based on most recent glucose level. The model was adjusted for baseline demographic and disease characteristics.FindingsParticipants with 12 or more peer educator visits per year had a 35% higher odds of glycemic control relative to participants with 4 or fewer visits (odds ratio 1.35, 95% CI: 1.08-1.69; p = 0.009), after adjustment for utilization of other treatment components (medication adherence, number of physician visits, number of lab tests), follow-up time, and demographic and disease characteristics. Better adherence to medications and a greater number of lab tests per year were also associated with a higher odds of glycemic control after adjustment. Number of physician consultations was not associated with glycemic control after adjustment.ConclusionsThis study demonstrates a positive association between peer educator utilization and glycemic control incremental to other elements of diabetes management. These results suggest that peer educators may be a valuable addition to comprehensive diabetes management programs in low- and middle-income countries even when other health care services are accessible. The associations identified in this research warrant further prospective studies to explore the causal impact of peer educators on glycemic control relative to other disease management components.

Background In many low- and middle-income countries (LMICs), heart disease and stroke are the leading causes of death as cardiovascular risk factors such as diabetes and hypertension rapidly increase. The Cambodian nongovernmental organization, MoPoTsyo, trains local residents with diabetes to be peer educators (PEs) to deliver chronic disease self-management training and medications to 14,000 people with hypertension and/or diabetes in Cambodia. We collaborated with MoPoTsyo to develop a mobile-based messaging intervention (mobile health; mHealth) to link MoPoTsyo’s database, PEs, pharmacies, clinics, and people living with diabetes and/or hypertension to improve adherence to evidence-based treatment guidelines. Objective This study aimed to understand the facilitators and barriers to chronic disease management and the acceptability, appropriateness, and feasibility of mHealth to support chronic disease management and strengthen community-clinical linkages to existing services. Methods We conducted an exploratory qualitative study using semistructured interviews and focus groups with PEs and people living with diabetes and/or hypertension. Interviews were recorded and conducted in Khmer script, transcribed and translated into the English language, and uploaded into Atlas.ti for analysis. We used a thematic analysis to identify key facilitators and barriers to disease management and opportunities for mHealth content and format. The information-motivation-behavioral model was used to guide data collection, analysis, and message development. Results We conducted six focus groups (N=59) and 11 interviews in one urban municipality and five rural operating districts from three provinces in October 2016. PE network participants desired mHealth to address barriers to chronic disease management through reminders about medications, laboratory tests and doctor’s consultations, education on how to incorporate self-management into their daily lives, and support for obstacles to disease management. Participants preferred mobile-based voice messages to arrive at dinnertime for improved phone access and family support. They desired voice messages over texts to communicate trust and increase accessibility for persons with limited literacy, vision, and smartphone access. PEs shared similar views and perceived mHealth as acceptable and feasible for supporting their work. We developed 34 educational, supportive, and reminder mHealth messages based on these findings. Conclusions These mHealth messages are currently being tested in a cluster randomized controlled trial (#1R21TW010160) to improve diabetes and hypertension control in Cambodia. This study has implications for practice and policies in Cambodia and other LMICs and low-resource US settings that are working to engage PEs and build community-clinical linkages to facilitate chronic disease management.

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.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 χA 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 (p0.001). 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.The levels of awareness, treatment and control of hypertension in this sample of Nepalese adults were low.

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.

OBJECTIVES: To compare longitudinal changes in healthcare costs between fallers admitted to the hospital at the time of the fall (admitted), those not admitted to the hospital (nonadmitted), and nonfaller controls; test hypotheses related to differences in mean costs between and within these groups over time; and estimate the costs attributable to falling. DESIGN: Longitudinal cohort. SETTING: Group Health Cooperative of Puget Sound. PARTICIPANTS: Seven thousand nine hundred ninety-three nonadmitted fallers, 976 admitted fallers, and 8,956 nonfallers aged 67 and older enrolled in an integrated healthcare delivery system. Fallers were identified according to fall-related E-Codes and International Classification of Diseases, Ninth Revision codes recorded between January 1, 2004, and December 31, 2006. Nonfallers were frequency matched on age group and sex. MEASUREMENTS: Quarterly costs during a 3-year period were modeled using generalized estimating equations. Covariates included index age, sex, RxRisk (a comorbidity adjuster), fall status, time, and interactions between fall status and time. RESULTS: Cost differences between the faller cohorts and nonfallers were greatest in quarters closest to the fall (all P Language: en

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.

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.

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.

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.

Objectives To determine whether outpatient care by fellowship-trained geriatricians is distinguishable from that of generalists caring for older patients.

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 ≤ 05). SS participants had lower adjusted total health care costs than control subjects in the first year after enrollment (−$1,633 [95% CI −$2,620 to −$646], P = 0.001), and adjusted total costs in year 2 trended lower (−$1,230 [−$2,494 to $33], P = 0.06). Participants who made on average ≥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 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.

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.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.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% (p0.05) 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).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.

OBJECTIVES To determine whether participation in a physical activity benefit by Medicare managed care enrollees is associated with lower healthcare utilization and costs.

Optimizing duration of participation in health promotion programs has important implications for program reach and costs. We examine data from 355 participants in EnhanceWellness to determine whether improvements in disability risk factors (depression, physical inactivity) occurred early or late in the enrollment period. Participants had a mean age of 74 years; 76% were women, and 16% were non-White. The percentage depressed declined from enrollment to 6 months (35% to 28%, p = .001) and from 6 to 12 months (28% to 22%, p = .03). The percentage physically inactive declined over the first 6 months, without substantial change thereafter (47%, 29%, and 29%). Those remaining inactive at 6 months had worse self-rated health and more depressive symptoms initially; a subset of those increased their physical activity by 12 months. These data suggest that enrollment could be reduced from 12 to 6 months without compromising favorable effects of EW participation, although additional benefits may accrue beyond 6 months.

OBJECTIVES: To assess the effect of a team of geriatrics specialists on the practice style of primary care providers (PCPs) and the functioning of their patients aged 75 and older. DESIGN: Randomized, controlled trial. SETTING: Two primary care clinics in the Seattle, Washington, area. PARTICIPANTS: Thirty-one PCPs and 874 patients aged 75 and older. INTERVENTION: An interdisciplinary team of geriatrics specialists worked with patients and providers to enhance the geriatric focus of care. MEASUREMENTS: Main outcomes were a practice style reflecting a geriatric orientation and patient scores on the physical and affect subscales of the Arthritis Impact Measurement Scale 2—Short Form. Secondary outcomes were hospitalizations, incident disability in activities of daily living (ADLs), and PCP perceptions of the intervention. Death rates were also assessed. RESULTS: Intervention providers screened significantly more for geriatric syndromes at 12 months, but this finding did not persist at 24 months. There were no significant differences in adequate hypertension control or high-risk prescribing at 12 or 24 months of follow-up. There were no significant differences in patient functioning or significant differences in hospitalization rates at either time point. Meaningful differences were observed in ADL disability at 12 but not 24 months. PCPs viewed the intervention favorably. Seventy-eight participants died over the 24 months of follow-up; the proportion dying was higher in the intervention group (11.4% in intervention group vs 7.1% of controls, P=.03). CONCLUSION: The addition of an interdisciplinary geriatric team was acceptable to PCPs and had some effect on care of geriatric conditions but little effect on patient function or the use of inpatient care and was associated with greater mortality.

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.

United States public hospitals and medical schools commonly enter into partnerships that serve the patient care, education, and research missions of both institutions. Harborview Medical Center, the county hospital in Seattle, Washington, and the University of Washington School of Medicine (UWSOM) have enjoyed a long affiliation that began at the medical school's founding 60 years ago. A formal agreement in 1967 turned over responsibility for all Harborview operations to UWSOM at a time when Harborview's facilities had fallen into serious disrepair and public hospitals were closing across the United States. All faculty and staff based at Harborview are employed by the University of Washington. By the mid-1970s a revitalization was underway at Harborview. The Medic One paramedic program drew national acclaim for pioneering prehospital emergency cardiac care, and the trauma and burn centers grew rapidly to meet specialized intensive care needs of the Pacific Northwest. Today, the success of the trauma, specialty surgery, and rehabilitation services have allowed Harborview to consistently maintain a positive operating margin while caring for the county's uninsured and indigent patients ($98 million in charity care in 2005). The hospital also offers nationally recognized residency programs and supports nationally and internationally acclaimed research. Harborview faces significant challenges for the future, including rapid growth of the indigent patient load, continually changing expectations for physician training, and growing cost pressures.

This study examined the effectiveness of participation in EnhanceFitness (EF) (formerly the Lifetime Fitness Program), an established community-based group exercise program for older adults. EF incorporated performance and health status measure testing in year 2000. Initial performance was compared to age and gender-based norms to classify participants as within or at or above normal limits (WNL) or below (BNL). In 2,889 participants who participated in outcomes testing, improvements were observed at 4 and 8 months on performance tests for both subgroups. Participants’ self-rating of health improved at 8 months. All participants improved on performance tests. Implementation of performance-based measures in community studies is possible. Challenges included selecting measures, staff training, collecting performance measures, and deciding on time points for data collection. Older adults can maintain and/or improve physical function through participation in EnhanceFitness.

Objective: To describe challenges in disseminating the Health Enhancement Program (HEP), a community-based disability prevention program for community dwelling elders, and to examine program effectiveness in geographically dispersed sites. Methods: Within-group, pre-test–post-test comparisons of disability risk factors, health and functional status, and hospitalizations for 115 participants completing one year in HEP, and primary care provider awareness and perceptions of the program. Results: Most (77%) participants were women, with an average age of 73 years and an average of 3.5 chronic conditions. At one-year follow-up, compared with enrollment, fewer participants were depressed (8.8% vs 15.9%), physically inactive (15.8% vs 38.6%), at high nutritional risk (24.3% vs 44.1%), or experiencing restricted activity days (35% vs 48%). Severity scores on most measures also improved significantly. The proportion hospitalized was unchanged from the year prior to HEP, although risk factors predicted an increase in hospitalizations as for the control group in the randomized trial. Conclusions: HEP reduced participants’ disability risk factors. Sites varied on numbers enrolled and time to implement the program, likely due to differing referral bases, degree of physician awareness of HEP, and site readiness. However, the benefits of HEP participation were comparable with those reported previously.

Objectives: To determine whether a clinic-based physical activity promotion intervention can lead to more community-based exercise referrals by providers and higher exercise motivation in patients. Design: Cluster randomized, controlled trial. Setting: Seattle Veterans Affairs General Internal Medicine Clinic. Participants: Thirty-one physicians and nurse practitioners were randomized to a physical activity counseling intervention or control condition (counseling about tobacco cessation). Three hundred thirty-six patients aged 50 and older and visiting a study provider were enrolled. Intervention: Intervention providers were trained to offer referrals to community exercise programs for patients who reported before their clinic visit that they were “contemplative” about regular exercise. Measurements: Process measures of health behavior assessment and provider advice, exercise stage-of-change, proportion of participants reporting regular physical activity. Results: At baseline, 172 intervention patients and 164 controls were similar with respect to sex, age, comorbidity score, and exercise motivation level. Forty-five percent of all intervention patients and 35% of controls reported receiving exercise advice (P=.07). Intervention patients who were contemplative about exercise were even more likely to receive exercise advice than contemplative controls (59% vs 38%; P=.02). After 4 months, 35% of all intervention patients reported regular exercise, compared with 28% of controls (P=.06). Conclusion: Primary providers are more likely to offer exercise advice when informed whether patients are contemplative about exercise. Patients may be more likely to start regular exercise as a result of this advice.

A practice style embodying traditional geriatric principles of care was not associated with a reduced likelihood of ADL disability over 4 years of follow-up (AOR for prescribing no high-risk medications=0.56, 95% CI=0.16-1.94; AOR for managing geriatric syndromes=0.94, 95% CI=0.40-2.19; AOR for a team care approach=1.35, 95% CI=0.66-2.75).ConclusionTaking care of a large number of elderly patients, obtaining a certificate of added qualifications in geriatrics, and practicing with a traditional geriatric orientation do not appear to influence the development of ADL disability in elder, community dwelling HMO enrollees.

Introduction Early detection and treatment for diabetes are essential for reducing disability and death from the disease. Finding effective screening and treatment for individuals living with diabetes in resource-limited countries is a challenge. MoPoTsyo, a Cambodian non-governmental organization, addressed this gap by utilizing a multi-pronged approach with community-based peer educators, access to laboratory procedures, local outpatient medical consultation, and a revolving drug fund. This study evaluated outcomes of MoPoTsyo’s diabetes program in Takeo Province by assessing glycemic and blood pressure outcomes for individuals diagnosed with diabetes over a 24-month follow-up period between 2007–2013. Methods This is a retrospective cohort analysis of records without a comparison group. We calculated the mean fasting blood glucose (FBG) and blood pressure (BP) at regular intervals of follow-up. The proportion of patients reaching recommended treatment targets for FBG and BP was assessed. Results Of the 3411 patients enrolled in the program, 2230 were included in the study. The cohort was predominantly female (68.9%) with a median age of 54 years. Median follow-up time in the program was 16 months (4.9–38.4 months). Mean FBG decreased 63.9 mg/dl in mean FBG (95% CI 58.5 to 69.3) at one year of follow-up (p

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.

Background. In 1993, the cardiac surgery community in Washington State opposed an effort by the state Health Care Authority (HCA) to identify "centers of excellence" for selective contracting of coronary artery bypass grafting (CABG) procedures, and proposed an alternate model that would create a statewide cardiac outcomes registry under physician governance to be used by all institutions for internal quality improvement activities. Methods. A prospective pilot data collection effort, which examined preoperative and postoperative patient-reported health status, served as the basis for evaluating the capacity of a physician-led organization to develop a collaborative atmosphere and facilitate universal hospital participation. Results. A surgical steering group met on a regular basis and reached consensus on governance issues, protocols for standardized data collection, and policies regarding data dissemination. All 14 centers that performed bypass surgery in the state participated. Patients who were surveyed reported statistically significant improvements in physical, emotional, and anginal-specific health status after bypass surgery. Baseline patient characteristics and longitudinal outcomes were compared across institutions. Conclusions. Based on the feasibility of this collaborative outcomes reporting program, the HCA revised its policy regarding selective contracting and has helped to support an ongoing physician-led and -governed cardiac outcomes reporting system that is particularly notable for the subsequent integration of both CABG surgery and catheterization-based procedures into one standardized registry.

Systematic approaches for compliance problem detection and intervention are needed if the benefits of prescribed drug therapy in chronic disease management are to be optimized. As with all measures of compliance, computer algorithms based on refill patterns have advantages and disadvantages. They are unobtrusive and easily determined, but they measure the timeliness of prescription refills, not actual drug-taking. Computer-generated algorithms for assessing compliance based on refill patterns should be used by practitioners with caution, because they are not only markers for potential drug taking compliance problems, but also for discrepancies between the medical chart, pharmacy records and verbal advice given to the patient. Because patients may obtain refills before depleting their supply, compliance rates using this methodology are best determined across several refills. In particular, we urge caution in applying them over time periods of less than 60 days. Longer minimum time periods further decrease the likelihood of "false positives" but limit the number of patients for whom a compliance measure can be computed. For the health professional (eg, the pharmacist) responsible for monitoring drug-taking compliance of patients, the message seems clear: when reviewing computer-generated noncompliance "flags," the first task is to fully explore the possibility of discrepancies in drug records before initiating compliance-related interventions.

This study investigated the differences between unprompted respondents, prompted respondents, and non-respondents to a postpartum postal survey, and determined the likely impact of non-response on the accuracy of calculations of patient assessments of obstetrical care quality. Birth certificate and hospital discharge data were obtained for 1664 live births at three hospitals in Washington State between 8/91–10/91 and linked with 1268 completed postpartum maternal postal surveys. Non-white race, public insurance payer, unmarried status, and smoking in pregnancy were independent risk factors for non-participation. Among participants, nonwhite race, unmarried status, and having an infant who was low birthweight, preterm, or discharged late were independent risk factors for prompted response. The inclusion of prompted respondents did not substantially alter the calculated proportion of women rating obstetrical care quality as low, and these figures were similar to proportions estimated for the entire intended cohort using a modification of Drane's method. A one-time mailing of an obstetrical care quality survey can provide information similar to that obtained with more extensive follow-up even though substantial differences may exist between unprompted and prompted respondents, and with adjustment for factors related to non-participation and timing of response, it may be possible to obtain accurate estimation of outcome prevalences for the entire intended cohort.

The authors measured the comorbid effect of alcohol and other drug (AOD) problems on medical, surgical, and psychiatric inpatient charges and length of stay (LOS) in an urban hospital by use of retrospective study of hospital clinical computer data comparing AOD-affected patients with non-AOD-affected patients in terms of cost, diagnostic, demographic, and utilization variables (N = 14,768). Patients were men and women with and without comorbid history of AOD problems, admitted for medical, surgical, and psychiatric reasons. For 10 of the 20 most frequent Diagnosis-Related Groups (DRGs), total hospital charges and LOS were significantly lower in patients with comorbid AOD problems (P < 0.001). Overall, for the most frequent 20 DRGs, total charges and LOS remained significantly lower for the AOD group. Most physicians believed that AOD-affected patients were often less ill than non-AOD patients within the same DRG. Alcohol/drug-affected patients had robustly lower costs and LOS. Fragmentation of psychosocial costs and addiction treatment from general health care and the fee-for-service DRG system appear to financially reward acute-care hospitals to repeatedly treat secondary AOD sequelae without providing any apparent incentives for the treatment of the primary alcohol/drug condition itself.

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

Introduction: Hypertension in Viet Nam is becoming an increasing source of mortality and morbidity. While data collection on hypertension in resource poor environments has been improving through the use of standardized surveys, little is known about how well treatments are being applied. Knowledge of gaps in diagnosis and treatment is necessary if appropriate public health programs are to developed. Using a community based observational sample in the Da Nang province of Viet Nam, we studied both the prevalence of undiagnosed hypertension, as well as the types of treatment those with hypertension received. Methods: Randomized cluster sampling methods were used to identify adults age 35 years and older in six communes of Da Nang province, Viet Nam. Using World Health Organization guidelines, data were collected on subject’s demographics, medical history, blood pressure and health behaviors. Subjects were also instructed to bring all medications they take regularly which were then recorded. Separate multivariate logistic regressions were used to identify both factors associated with awareness of hypertension as well as factors influencing whether one received medical therapy. Results: The initial survey examined 1,621 adults with 557 (34.5%) having hypertension. Of those, only 232 (41.7%) were aware of the diagnosis. Being male (OR 0.52, 95% CI: 0.36–0.75), older (OR 1.03, 95% CI: 1.02–1.05 per year) and having a low income (OR 1.11, 95% CI: 1.05–1.16 per million dong/month) were each independently associated with being unaware of one’s hypertension. Of those who were aware of their hypertension, 212 (91.4%) had been recommended some behavioral modification (exercise, decreased sodium intake, smoking cessation, or weight loss). Two-thirds (152/229) reported having taken antihypertensives in the past two weeks. Reported use of medication differed by region, 109/150 (72.7%) in urban regions versus 43/79 (54.4%) in rural/mixed-urban regions (p Conclusions: Undiagnosed hypertension remains a major health problem in the Da Nang province of Viet Nam. The vast majority of those aware of their hypertension were receiving at least some level of behavioral modification with a smaller, but substantial, majority receiving medications. Screening programs focused on young and poor men may be a rich target for improving hypertension control in Viet Nam.

Despite guidelines to direct appropriate medical management, the quality of care following acute myocardial infarction (AMI) may be lacking. This study characterizes medication utilization by Medicaid enrollees in the year following AMI, compares it to guidelines for secondary prevention and investigates associations with rehospitalization and survival. Using DSHS administrative claims data from Washington State, Medicaid enrollees who had an AMI in 2004 were selected. Data were de-identified and details of demographics, hospitalizations, ambulatory care, and prescriptions over the following 365 days were abstracted. Utilization of guideline-directed secondary prevention strategies was measured and associations with death and recurrent hospitalization were tested. The mortality rate was 13.4% and 38.7% were rehospitalized. Mean time to first rehospitalization was 188.6 days (SD 102.3). Prescriptions for angiotensin enzyme inhibitors or receptor blockers were initially filled by 54.0%, but year-long adherence declined to 33.3%. Beta blockers, aspirin and statins followed the same trend: 65.1% to 39.5%, 37.9% to 16.7% and 58.1% to 41.9% respectively. Twenty-two percent received all medications; 8.2% were adherent. Only the initial prescription of aspirin was significantly associated with a survival benefit (HR = 0.35, p=0.003). If the results suggested by the claims data are representative of care delivered to Medicaid enrollees, rates of application of guideline-directed medication are less than optimal. To improve survival and reduce re-hospitalization following AMI, changes in the access and delivery of healthcare could be implemented to improve medication management, both at time of discharge and over the year following AMI.

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.

The Foundation for Health Care Quality (Washington) used three administrative public databases and indicators recommended by the Joint Commission and the American College of Obstetrics and Gynecology to build algorithms to measure quality of obstetric care in the state of Washington. Analyses demonstrated a high degree of variability across hospitals for major processes of care such as cesarean section, vaginal birth after cesarean section, and forceps deliveries. Eighty-five percent of the participating hospitals concluded that important aspects of care were being measured. Ninety-four percent found the information useful in describing their performance compared with other hospitals. Sixty-two percent believed the information was useful for initiating quality improvement projects. Of the 25 indicators tested in the project, indicators rated as most useful were the same 10 obstetric indicators chosen by the Joint Commission after alpha testing.

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.

Background: It is estimated that major depressive disorder affects 0.9% of community-dwelling older adults in the United States. However, as many as 18% of older US adults reportedly suffer from depressive symptoms that do not necessarily fit the criteria for major depressive disorder (eg, dysthmia, minor depression). Objectives: The goals of this study were to describe patterns of antidepressant medication use in older adults with dysthymia or minor depression and to examine factors associated with the use of antidepressants at baseline. Methods: This was a secondary analysis using cross-sectional data collected during a randomized controlled trial conducted from 2000 through 2003. It involved community senior service agencies and in-home visits in Seattle, Washington. Adults aged ≥60 years who had minor depression or dysthymia and were receiving services through community senior service agencies or living in senior public housing were included. Study participants were classified as users or nonusers of antidepressants. Prescription medication use in the past 2 weeks was assessed at baseline and 6 and 12 months. Medication name, dose, and directions were recorded from the medication label. Logistic regression was used to examine variables associated with baseline antidepressant use. Results: A total of 138 patients (mean age, 73.00 years) were included; the majority of study participants were female (779.00%). Overall, 42.33% were nonwhite (34.3% black, 4.4% Asian, 1.5% American Indian/Alaskan Native, 0.7% Hispanic, and 1.5% other). At baseline, 36.2% of study participants (n = 50) were using antidepressants. Selective serotonin reuptake inhibitors were the most common class of antidepressants, used by 62.00%, 70.22%, and 71.11% of antidepressant users at baseline, 6, and 12 months, respectively. However, nortriptyline was the most common antidepressant at baseline, taken by 20.00% of antidepressant users. Use of other prescription medications was associated with antidepressant use at baseline. Conclusions: We found antidepressant use to be low in these relatively poor, community-dwelling, ethnically diverse older adults with dysthymia and minor depression in 2000 through 2003, with 36.22% of participants using antidepressants at baseline. Antidepressant users were more likely to be taking other prescription medications than nonusers.

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.

Background Regular physical activity is an important goal for elders with chronic health conditions. Context This report describes Physical Activity for a Lifetime of Success (PALS), an attempt to translate a motivational support program for physical activity, Active Choices, for use by a group of diverse, low-income, community-dwelling elders with diabetes. Methods PALS linked physical activity assessment and brief counseling by primary care providers with a structured referral to a community-based motivational telephone support program delivered by older adult volunteers. People with diabetes aged 65 years or older who were receiving care at two community clinics were randomized to receive either immediate or delayed intervention. The main intended outcome measure was physical activity level; the secondary outcome measure was mean hemoglobin A1c. Consequences One-third of those offered referral to the PALS program in the clinic setting declined. Another 44% subsequently declined enrollment or were unreachable by the support center. Only 14 (21%) of those offered referral enrolled in the program. Among these 14, the percentage who were sufficiently active was higher at follow-up than at enrollment, though not significantly so. Using an intent-to-treat analysis, which included all randomized clinic patients, we found no significant change in mean hemoglobin A1c for the intervention group compared with controls. Interpretation A community-based referral and support program to increase physical activity among elderly, ethnically diverse, low-income people with diabetes, many of whom are not English-speaking, may be thwarted by unforeseen barriers. Those who enroll and participate in the PALS program appear to increase their level of physical activity.

To assess the effect of a team of geriatrics specialists on the practice style of primary care providers (PCPs) and the functioning of their patients aged 75 and older.Randomized, controlled trial.Two primary care clinics in the Seattle, Washington, area.Thirty-one PCPs and 874 patients aged 75 and older.An interdisciplinary team of geriatrics specialists worked with patients and providers to enhance the geriatric focus of care.Main outcomes were a practice style reflecting a geriatric orientation and patient scores on the physical and affect subscales of the Arthritis Impact Measurement Scale 2-Short Form. Secondary outcomes were hospitalizations, incident disability in activities of daily living (ADLs), and PCP perceptions of the intervention. Death rates were also assessed.Intervention providers screened significantly more for geriatric syndromes at 12 months, but this finding did not persist at 24 months. There were no significant differences in adequate hypertension control or high-risk prescribing at 12 or 24 months of follow-up. There were no significant differences in patient functioning or significant differences in hospitalization rates at either time point. Meaningful differences were observed in ADL disability at 12 but not 24 months. PCPs viewed the intervention favorably. Seventy-eight participants died over the 24 months of follow-up; the proportion dying was higher in the intervention group (11.4% in intervention group vs 7.1% of controls, P=.03).The addition of an interdisciplinary geriatric team was acceptable to PCPs and had some effect on care of geriatric conditions but little effect on patient function or the use of inpatient care and was associated with greater mortality.

We reported previously the results of a randomized controlled trial of a home-based behavioral treatment for dysthymia or minor depression that emphasized problem solving and activity scheduling among low-income, medically ill older adults. This report focuses on the content of treatment sessions as predictors of depressive symptoms, social activity, and physical activity outcomes among 64 participants who completed 2 or more sessions and evaluations at 6 and 12 months after the baseline evaluation. Worksheets from the treatment sessions were coded for focus on 4 types of problems (functional, social, health/physical, emotional); the number of activities planned was counted. More activity scheduling was associated with increased physical activity at the 12-month evaluation relative to baseline. The limited findings suggest either that the study methodology did not reveal extant associations between treatment variables and outcomes or that the session content variables tested in this study are not the active ingredients of treatment.

OBJECTIVE—The purpose of this article was to determine the effects of a managed-Medicare physical activity benefit on health care utilization and costs among older adults with diabetes. RESEARCH DESIGN AND METHODS—This retrospective cohort study used administrative and claims data for 527 patients from a diabetes registry of a staff model HMO. Participants (n = 163) were enrolled in the HMO for at least 1 year before joining the Enhanced Fitness Program (EFP), a community-based physical activity program for which the HMO pays for each EFP class attended. Control subjects were matched to participants according to the index date of EFP enrollment (n = 364). Multivariate regression models were used to determine 12-month postindex differences in health care use and costs between participants and control subjects while adjusting for age, sex, chronic disease burden, EFP attendance, prevention score, heart registry, and respective baseline use and costs. RESULTS—Participants and control subjects were similar at baseline with respect to age (75 ± 5.5 years), A1C levels (7.4 ± 1.4%), chronic disease burden, prevention score, and health care use and costs. After exposure to the program, there was a trend toward lower hospital admissions in EFP participants compared with control subjects (13.5 vs. 20.9%, P = 0.08), whereas total health care costs were not different (P = 0.39). EFP participants who attended ≥1 exercise session/week on average had ∼41% less total health care costs compared with those attending CONCLUSIONS—Although elective participation in a community-based physical activity benefit at any level was not associated with lower inpatient or total health care costs, greater participation in the program may lower health care costs. These findings warrant additional investigations to determine whether policies to offer and promote a community-based physical activity benefit in older adults with diabetes can reduce health care costs.

This study evaluated the effect of distance on the likelihood of initiating and maintaining regular use of a fitness-program benefit in a population of managed Medicare seniors. We studied 8,162 participants and nonparticipants in a managed-care fitness-program benefit: a structured group exercise program or an unstructured health-club membership. Participants in both programs lived significantly closer to facilities than nonparticipants did (structured, p < .001; unstructured, p = .017). Participants living closer to unstructured-program sites attended more frequently than those farther away (p = .008). Distance was not correlated with frequency of use in the structured program (p = .49). Collectively, these analyses demonstrate that distance is related to uptake and, in some cases, continued use of a fitness-program benefit. Health systems providing fitness-program benefits as a way to increase physical activity levels of their plan members should consider location of program facilities in relation to members’ home addresses to maximize use of the benefit.
