Developing a comprehensive interdisciplinary senior healthcare practice

The PeaceHealth Senior Health and Wellness Center (SHWC) provides primary care coordinated by geriatricians and an interdisciplinary office practice team that addresses the multiple needs of geriatric patients. The SHWC is a hospital outpatient clinic operated as a component of an integrated health system and is focused on the care of frail elders with multiple interacting chronic conditions and management of chronic disease in the healthier older population. Based on the Chronic Care Model, the SHWC strives to enhance coordination and continuity along the continuum of care, including outpatient, inpatient, skilled nursing, long-term care, and home care services. During its development, a patient-centered approach was used to identify senior service needs. The model emphasizes team development, integration of evidence-based geriatric care, site-based care coordination, longer appointment times, "high touch" service qualities, utilization of an electronic medical record across care settings, and a prevention/wellness orientation. This collection of services addresses the interrelationships of all senior issues, including nutrition, social support, spiritual support, caregiver support, physical activity, medications, and chronic disease. The SHWC provides access in an environment sensitive to the special needs of seniors, with a staff trained to meet those needs. The SHWC business model attempts to improve access and quality of care to seniors in a mostly noncapitated healthcare setting, while also attempting to remain financially viable.     

Chronic Care Management Services for Complex Diabetes Management: a Practical Overview

Purpose of Review

Formalized chronic care management has the potential to improve the quality and cost-effectiveness of complex diabetes management in adults, but has historically not been sustainably supported by health care systems. This review discusses the application of the chronic care model in the care of complex diabetes and its translation in the current reimbursement structure designed by Centers for Medicare and Medicaid Services (CMS).

Recent Findings

Following the introduction of Wagner’s Chronic Care Model (CCM) in the late 1990s, evidence gathered over the past 2 decades has supported the shift in focus of health care systems from acute to chronic disease management and proactive care. Acknowledging evidence and potential for improved cost-effectiveness, in 2015, Medicare began reimbursing for chronic care management services (CCMS) for patients with multiple chronic conditions. The CCMS billing codes allow a program to be reimbursed for up to 90 min per month spent by clinical staff performing interim care within a comprehensive care plan. Recent data from local and global programs support the application of formalized CCM in diabetes management.

Summary

Although reimbursement models for CCM have been designed for use in primary care, the challenges of the reimbursement model has opened the door for specialty areas focused on multimorbidity care such as diabetes care to explore this approach. With the broader availability of remote glucose monitoring and telemedicine, a strategy that combines goal-oriented care and telehealth solutions appears to be most effective in diabetes CCM care. Despite widespread acceptance of the chronic care model of care, there remain significant barriers to its incorporation into standard practice.

     

Age, functional capacity, and health-related quality of life in patients with heart failure

BACKGROUND: Although heart failure disproportionately affects older persons and is associated with significant physical disability, existing data on physical limitations and health-related quality of life (HRQL) derive largely from studies of younger subjects. We compared the relationship between functional limitation and HRQL between older and younger patients with heart failure. METHODS AND RESULTS: We evaluated 546 outpatients with heart failure enrolled in a multicenter prospective cohort study. At baseline and 6 +/- 2 weeks later, functional status was assessed by New York Heart Association (NYHA) classification and 6-minute walk testing. HRQL was measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ). Comparing older (age >65 years, n = 218) and younger patients (n = 328), we assessed baseline HRQL across strata of functional status. In the 484 patients who completed follow-up (194 older and 290 younger patients), we also assessed the changes in HRQL associated with changes in functional status over time. At baseline, older patients had better HRQL than younger patients (mean KCCQ score 60 +/- 25 versus 54 +/- 28, P = .005) in spite of worse NYHA class (mean 2.54 versus 2.35, P < .001) and lower 6-minute walk distances (824 +/- 378 versus 1064 +/- 371 feet, P < .001). After multivariable adjustment including baseline NYHA class, older age was independently correlated with better HRQL (beta = +7.9 points, P < .001). At follow-up, older patients with a deterioration in NYHA class experienced marked declines in HRQL compared with younger patients (mean HRQL change of -14.4 points versus +0.3 points, respectively, P < .001). Analyses using 6-minute walk distance as the functional measure yielded similar results. CONCLUSIONS: Although older patients with heart failure have relatively good HRQL in spite of significant functional limitations, they are at risk for worsening HRQL with further decline in functional status. These results underscore the importance of treatments aimed at maintaining functional status in older persons with heart failure, including those with significant baseline functional limitations.     

Overcoming Roadblocks: Current and Emerging Reimbursement Strategies for Integrated Mental Health Services in Primary Care

The Chronic Care Model (CCM) has been shown to improve medical and psychiatric outcomes for persons with mental disorders in primary care settings, and has been proposed as a model to integrate mental health care in the patient-centered medical home under healthcare reform. However, the CCM has not been widely implemented in primary care settings, primarily because of a lack of a comprehensive reimbursement strategy to compensate providers for day-to-day provision of its core components, including care management and provider decision support. Drawing upon the existing literature and regulatory guidelines, we provide a critical analysis of challenges and opportunities in reimbursing CCM components under the current fee-for-service system, and describe an emerging financial model involving bundled payments to support core CCM components to integrate mental health treatment into primary care settings. Ultimately, for the CCM to be used and sustained over time to integrate physical and mental health care, effective reimbursement models will need to be negotiated across payers and providers. Such payments should provide sufficient support for primary care providers to implement practice redesigns around core CCM components, including care management, measurement-based care, and mental health specialist consultation.     

The Senior Care Study. A controlled trial of a consultative/unit-based geriatric assessment program in acute care

Successful models of inpatient geriatric assessment have often involved long hospital stays, specialized interdisciplinary care, and prolonged follow-up, which are difficult to achieve within a prospective payment system. A randomized clinical trial was undertaken to evaluate the efficacy (maintenance or improvement in mental, emotional, and physical function) of using a geriatric assessment process in acute hospital care without increasing hospital charges or lengths of stay. Four hundred thirty-six patients greater than or equal to 75 years of age were randomly allocated to treatment (n = 221) or control (n = 215) conditions. Patients in the treatment group were admitted to a special unit and evaluated on admission by an interdisciplinary team, which developed a care plan. Although primary care was provided by the patient's own physician, the team followed the patients as consultants on the unit in the hospital, and by telephone for 2 months after discharge. The control group was placed on other units and received usual hospital care. The treatment and control groups were similar at study entry. At follow-up, there were no significant differences between the groups with respect to lengths of stay, hospital charges, mortality, change in physical function, or change in mental function. The treatment group changed more often in measured emotional function (chi 2 = 6.213, P = .045). This study indicates that it is feasible to implement consultative interdisciplinary team care in the acute-care hospital, but that its efficacy may be limited when applied to an unselected group of older patients.     

Linking changes in quality of life to haematologic response and survival in systemic immunoglobulin light-chain amyloidosis

This study reports health-related quality of life (HRQL) among newly-diagnosed immunoglobulin light-chain (AL) patients (n = 914) treated with a bortezomib-based regimen and its association with response depth and survival. Haematologic response/HRQL were assessed over 24 months in an ongoing, prospective study. HRQL change was calculated across haematologic/cardiac response levels. The relationship between baseline HRQL and survival was evaluated by the Cox proportional-hazard model (PH). Shared-random-effects models (SREMs) estimated time-to-death conditional on current HRQL/longitudinal HRQL trajectory. At 3 months, there was consistent decline in 5/8 HRQL domains across all haematologic response levels. By 12 months, 3/5 declining domains improved among complete response (CR) patients. In contrast, the mean change in less-than-CR patients did not indicate improvement. Under the Cox PH, having a baseline HRQL score five points higher than the sample mean was associated with 20% lower mortality risk. SREMs indicated a five-point greater HRQL score at the event time correlated with an approximately 30% decrease in mortality risk. For each one-point increase in HRQL score trajectory slope, mortality risk decreased by approximately 88%. Only CR patients had HRQL improvement, while partial response patients had less decline but no meaningful improvements. These data show the importance of HRQL serial assessments of AL patients and its importance as an end-point.     

Fall-risk assessment and management in clinical practice: views from healthcare providers

OBJECTIVES: To determine the extent to which healthcare providers reportedly address evidence-based fall risk factors in older patients after exposure to an educational intervention and to determine barriers reportedly encountered when these healthcare providers intervene with or refer older patients with identified fall-risk factors. DESIGN: Cross-sectional study using a structured interview. SETTING: Geographic area of Connecticut where the Connecticut Collaboration for Fall Prevention (CCFP) has been implemented. PARTICIPANTS: Emergency department (ED) physicians, hospital-based discharge planners or care coordinators (nurses or social workers), home health agency nurses, and office-based primary care physicians (total n=33) after exposure to the CCFP implementation team. MEASUREMENTS: Self-reported practices (direct intervention or referral) and barriers when addressing seven evidence-based risk factors for falls: gait and transfer impairments, balance disturbances, multiple medications, postural hypotension, sensory and perceptive deficits, foot and footwear problems, and environmental hazards. RESULTS: Respondents were most likely to report directly intervening with or referring older patients for gait and transfer impairments (85%) and balance disturbances (82%) and least likely to do so when encountering foot or footwear problems (58%) and sensory or perceptive deficits (61%). ED physicians reported lowest rates of direct intervention or referral for foot or footwear problems (20%), home health agency nurses for sensory or perceptive deficits (50%), and office-based primary care physicians for foot or footwear problems (50%). Patient compliance was the most commonly reported barrier to successful direct intervention across several risk factors, whereas inadequate availability of other healthcare providers and lack of Medicare reimbursement were the most commonly reported barriers to successful patient referrals. CONCLUSION: After exposure to the CCFP implementation team, the majority of healthcare providers reported directly intervening or referring patients when addressing all risk factors, but results pinpointed specific healthcare provider groups with room for improvement in assessment and management of specific risk factors. Patient education appears to be a necessary adjunct to healthcare provider training, because patient compliance was a reported barrier to optimal intervention by healthcare providers.     

Use of Chronic Care Management Codes for Medicare Beneficiaries: a Missed Opportunity?

Background

Physicians spend significant time outside of regular office visits caring for complex patients, and this work is often uncompensated. In 2015, the Centers for Medicare & Medicaid Services (CMS) introduced a billing code for care coordination between office visits for beneficiaries with multiple chronic conditions.

Objective

Characterize use of the Chronic Care Management (CCM) code in New England in 2015.

Design

Retrospective observational analysis.

Participants

All Medicare fee-for-service beneficiaries in New England continuously enrolled in Parts A and B in 2015.

Intervention

None.

Main measures

The primary outcome was the number of beneficiaries with a CCM claim per 1000 eligible beneficiaries. Secondary outcomes included the total number of CCM claims, total reimbursement, mean number of claims per beneficiary, and beneficiary characteristics independently associated with receiving CCM services.

Key results

Of the more than two million Medicare fee-for-service beneficiaries in New England, almost 1.7 million were potentially eligible for CCM services. Among eligible beneficiaries, 10,951 (0.65%) had a CCM claim in 2015. Massachusetts had the highest penetration of CCM use (9.40 claims per 1000 eligible beneficiaries); Vermont had the lowest (0.54 claims per 1000 eligible beneficiaries). Mean reimbursement per physician was $1745.98. Age, race/ethnicity, dual-eligible status, income, number of chronic conditions, and state of residence were associated with receiving CCM services in an adjusted model.

Conclusions

The CCM code is likely underutilized in New England; the program may therefore not be achieving its intended goal of encouraging consistent, team-based chronic care management for Medicare’s most complex beneficiaries. Or practices may be foregoing reimbursement for care coordination that they are already providing. Recently implemented revisions may improve uptake of CCM services; it will be important to compare our results with future utilization.

     

Differences in sustainability of exercise and health-related quality of life outcomes following home or hospital-based cardiac rehabilitation.

BACKGROUND: Home-based cardiac rehabilitation (CR) has been demonstrated to be as effective as institution-based CR in post-coronary artery bypass graft surgery (CABG) patients in terms of short-term physical and psychosocial outcomes. The sustainability of these effects is less well studied. The aim of this study was to examine the sustainability of observed changes in physical, quality of life (HRQL), and social support (SS) outcomes in patients 12 months after discharge from a randomized controlled trial (RCT) of 6 months of monitored home-based versus supervised hospital-based CR. DESIGN: Two-hundred and twenty-two (n=222) patients were followed-up 12 months after discharge from a RCT of 6 months of monitored 'Home' versus supervised 'Hospital' CR after CABG. METHODS: At discharge from the 6-month RCT, participants who consented to the 12-month follow-up study, were given individualized guidelines for ongoing exercise, and were not contacted for 1 year. The primary outcome was peak oxygen uptake (VO2). Secondary outcomes were: HRQL, SS and habitual physical activity. RESULTS: One hundred and ninety-eight patients (89.2%), 102 'Hospital' and 96 'Home', returned for follow-up 12-months after discharge from CR. Both groups had similar medical and socio-demographic characteristics. Peak VO2 declined in 'Hospital' but was sustained in 'Home' patients 12 months after discharge from CR (P=0.002). Physical HRQL was higher in the 'Home' group at the 12-month follow-up (P<0.01). Mental HRQL showed general, minor deterioration over time in both groups (P=0.019). Twelve months after discharge from CR, physical and mental HRQL remained higher than at entry to CR in both groups. 'Home' patients had higher habitual physical activity scores compared to 'Hospital' patients. CONCLUSIONS: This follow-up study suggests that low-risk patients whose CR is initiated in the home environment may be more likely to sustain positive physical and psychosocial changes over time than patients whose program is initially institution-based.     

Delivering effective primary care to older adults: a randomized, controlled trial of the senior resource team at group health cooperative

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.     

Home mechanical ventilation for restrictive thoracic diseases: effects on patient quality-of-life and hospitalizations

Forty-five patients with restrictive respiratory diseases, including thoracic wall diseases (TWD, n = 27) and neuromuscular diseases (NMD, n = 18), underwent 18 months of home mechanical ventilation (HMV) treatment. Treatment consisted of a two-level pressure system for 7h at night, with oxygen available if needed. Questionnaire-based assessments of health-related quality-of-life (HRQL) were evaluated before treatment and at 3, 6, 9, 12 and 18 months of follow-up. Hospitalization rates pre- and post-treatment were recorded, and the numbers need to treat (NNT) to avoid hospitalization and absolute risk reduction (ARR) rates were calculated. Several categories of HRQL, including physical function and vitality, improved significantly with treatment in both groups of patients; these improvements persisted over the entire 18 months. In contrast, other categories such as social function and mental health improved initially and declined subsequently. Hospitalizations decreased significantly with treatment. NNT calculations indicated that treatment would be needed for two TWD patients (ARR 63%) and one NMD patient (ARR 78%) to prevent one hospitalization per year per disease group. We conclude that improved quality-of-life and decreased hospitalizations make home non-invasive mechanical ventilation an useful treatment for patients with restrictive respiratory disorders.     

Treatment of depression improves physical functioning in older adults

OBJECTIVES: To determine the effect of collaborative care management for depression on physical functioning in older adults. DESIGN: Multisite randomized clinical trial. SETTING: Eighteen primary care clinics from eight healthcare organizations. PARTICIPANTS: One thousand eight hundred one patients aged 60 and older with major depressive disorder. INTERVENTION: Patients were randomized to the Improving Mood: Promoting Access to Collaborative Treatment (IMPACT) intervention (n=906) or to a control group receiving usual care (n=895). Control patients had access to all health services available as part of usual care. Intervention patients had access for 12 months to a depression clinical specialist who coordinated depression care with their primary care physician. MEASUREMENTS: The 12-item short form Physical Component Summary (PCS) score (range 0-100) and instrumental activities of daily living (IADLs) (range 0-7). RESULTS: The mean patient age was 71.2, 65% were women, and 77% were white. At baseline, the mean PCS was 40.2, and the mean number of IADL dependencies was 0.7; 45% of participants rated their health as fair or poor. Intervention patients experienced significantly better physical functioning at 1 year than usual-care patients as measured using between-group differences on the PCS of 1.71 (95% confidence interval (CI)=0.96-2.46) and IADLs of -0.15 (95% CI=-0.29 to -0.01). Intervention patients were also less likely to rate their health as fair or poor (37.3% vs 52.4%, P<.001). Combining both study groups, patients whose depression improved were more likely to experience improvement in physical functioning. CONCLUSION: The IMPACT collaborative care model for late-life depression improves physical function more than usual care.     

The efficacy of counseling and progressive resistance home-exercises on adherence, health-related quality of life and function after discharge from a geriatric day-hospital

Loss of function and low exercise adherence is common among older people after hospitalization. The aim of this randomized-controlled trial was to evaluate the effects of a combined counseling- and exercise program on changes in health-related quality of life (HRQL) and physical function in patients attending a day hospital and continuing exercise at home. The exercise program consisted of counseling, balance- and progressive resistance training and support from the physical therapist at Geriatric Day-Hospital (GDH) and home for the Intervention-group. The Control-group received counseling, balance-training and support from the physical therapist. The sample was recruited from a GDH in Norway. 108 participants were randomized into the Intervention group (IT) (n=53) or the Control group (CT) (n=55). After 3 months 77 participants were tested. The intention to treat analysis showed that the program had significant benefits in terms of Health Related Quality of Life, measured by SF-36, on the domains vitality and bodily pain, in favor of the IT-group who performed the combined resistance exercises and balance program. All participants increased their scores on physical function, measured by Berg Balance Scale, Timed Up and Go, 5 times Sit-to-Stand, 6Min Walk Test and Activities Balance Confidence Scale, no group differences. Both groups were adherent to the home exercise program The results show that it is possible to facilitate older people to increase their HRQL, physical function and level of physical activity through counseling, exercise and support from physical therapists.     

Community-Partnered Cluster-Randomized Comparative Effectiveness Trial of Community Engagement and Planning or Resources for Services to Address Depression Disparities

BACKGROUND

Depression contributes to disability and there are ethnic/racial disparities in access and outcomes of care. Quality improvement (QI) programs for depression in primary care improve outcomes relative to usual care, but health, social and other community-based service sectors also support clients in under-resourced communities. Little is known about effects on client outcomes of strategies to implement depression QI across diverse sectors.

OBJECTIVE

To compare the effectiveness of Community Engagement and Planning (CEP) and Resources for Services (RS) to implement depression QI on clients’ mental health-related quality of life (HRQL) and services use.

DESIGN

Matched programs from health, social and other service sectors were randomized to community engagement and planning (promoting inter-agency collaboration) or resources for services (individual program technical assistance plus outreach) to implement depression QI toolkits in Hollywood-Metro and South Los Angeles.

PARTICIPANTS

From 93 randomized programs, 4,440 clients were screened and of 1,322 depressed by the 8-item Patient Health Questionnaire (PHQ-8) and providing contact information, 1,246 enrolled and 1,018 in 90 programs completed baseline or 6-month follow-up.

MEASURES

Self-reported mental HRQL and probable depression (primary), physical activity, employment, homelessness risk factors (secondary) and services use.

RESULTS

CEP was more effective than RS at improving mental HRQL, increasing physical activity and reducing homelessness risk factors, rate of behavioral health hospitalization and medication visits among specialty care users (i.e. psychiatrists, mental health providers) while increasing depression visits among users of primary care/public health for depression and users of faith-based and park programs (each p?<?0.05). Employment, use of antidepressants, and total contacts were not significantly affected (each p?>?0.05).

CONCLUSION

Community engagement to build a collaborative approach to implementing depression QI across diverse programs was more effective than resources for services for individual programs in improving mental HRQL, physical activity and homelessness risk factors, and shifted utilization away from hospitalizations and specialty medication visits toward primary care and other sectors, offering an expanded health-home model to address multiple disparities for depressed safety-net clients.     

Better Access,Quality, and Cost for Clinically Complex Veterans with Home‐Based Primary Care

In successfully reducing healthcare expenditures, patient goals must be met and savings differentiated from cost shifting. Although the Department of Veterans Affairs (VA) Home Based Primary Care (HBPC) program for chronically ill individuals has resulted in cost reduction for the VA, it is unknown whether cost reduction results from restricting services or shifting costs to Medicare and whether HBPC meets patient goals. Cost projection using a hierarchical condition category (HCC) model adapted to the VA was used to determine VA plus Medicare projected costs for 9,425 newly enrolled HBPC recipients. Projected annual costs were compared with observed annualized costs before and during HBPC. To assess patient perspectives of care, 31 veterans and caregivers were interviewed from three representative programs. During HBPC, Medicare costs were 10.8% lower than projected, VA plus Medicare costs were 11.7% lower than projected, and combined hospitalizations were 25.5% lower than during the period without HBPC. Patients reported high satisfaction with HBPC team access, education, and continuity of care, which they felt contributed to fewer exacerbations, emergency visits, and hospitalizations. HBPC improves access while reducing hospitalizations and total cost. Medicare is currently testing the HBPC approach through the Independence at Home demonstration.     

The Italian multicentre study on noninvasive ventilation in chronic obstructive pulmonary disease patients.

Chronic obstructive pulmonary disease (COPD) patients with chronic ventilatory failure (CVF) are more likely to develop exacerbations, which are an important determinant of health-related quality of life (HRQL). Long-term noninvasive positive-pressure ventilation (NPPV) has been proposed in addition to long-term oxygen therapy (LTOT) to treat CVF but little information is available on its effects on HRQL and resource consumption. Therefore, the current authors undertook a 2-yr multicentric, prospective, randomised, controlled trial to assess the effect of NPPV+ LTOT on: 1) severity of hypercapnia; 2) use of healthcare resources, and 3) HRQL, in comparison with LTOT alone. One hundred and twenty-two stable hypercapnic COPD patients on LTOT for > or = 6 months were consecutively enrolled. After inclusion and 1-month run-in, 90 patients were randomly assigned to NPPV+LTOT (n=43) or to LTOT alone (n=47). Arterial blood gases, hospital and intensive care unit (ICU) admissions, total hospital and ICU length of stay and HRQL were primary outcome measures; survival and drop-out rates, symptoms (dyspnoea and sleep quality) and exercise tolerance were secondary outcome measures. Follow-up was performed at 3-month intervals up to 2 yrs. Lung function, inspiratory muscle function, exercise tolerance and sleep quality score did not change over time in either group. By contrast the carbon dioxide tension in arterial blood on usual oxygen, resting dyspnoea and HRQL, as assessed by the Maugeri Foundation Respiratory Failure Questionnaire, changed differently over time in the two groups in favour of NPPV+LTOT. Hospital admissions were not different between groups during the follow-up. Nevertheless, overall hospital admissions showed a different trend to change in the NPPV+LTOT (decreasing by 45%) as compared with the LTOT group (increasing by 27%) when comparing the follow-up with the follow-back periods. ICU stay decreased over time by 75% and 20% in the NPPV+LTOT and LTOT groups, respectively. Survival was similar. Compared with long-term oxygen therapy alone, the addition of noninvasive positive-pressure ventilation to long-term oxygen therapy in stable chronic obstructive pulmonary disease patients with chronic ventilatory failure: 1) slightly decreased the trend to carbon dioxide retention in patients receiving oxygen at home and 2) improved dyspnoea and health-related quality of life. The results of this study show some significant benefits with the use of nocturnal, home noninvasive positive-pressure ventilation in patients with chronic ventilatory failure due to advanced chronic obstructive pulmonary disease patients. Further work is required to evaluate the effect of noninvasive positive-pressure ventilation on reducing the frequency and severity of chronic obstructive pulmonary disease exacerbation.     

VA and Medicare Utilization Among Dually Enrolled Veterans with Type 2 Diabetes: A Latent Class Analysis

BACKGROUND

Many Veterans treated within the VA Healthcare System (VA) are also enrolled in fee-for-service (FFS) Medicare and receive treatment outside the VA. Prior research has not accounted for the multiple ways that Veterans receive services across healthcare systems.

OBJECTIVE

We aimed to establish a typology of VA and Medicare utilization among dually enrolled Veterans with type 2 diabetes.

DESIGN

This was a retrospective cohort.

PARTICIPANTS

316,775 community-dwelling Veterans age ≥ 65 years with type 2 diabetes who were dually enrolled in the VA and FFS Medicare in 2008–2009.

METHODS

Using latent class analysis, we identified classes of Veterans based upon their probability of using VA and Medicare diabetes care services, including patient visits, laboratory tests, glucose test strips, and medications. We compared the amount of healthcare use between classes and identified factors associated with class membership using multinomial regression.

KEY RESULTS

We identified four distinct latent classes: class 1 (53.9 %) had high probabilities of VA use and low probabilities of Medicare use; classes 2 (17.2 %), 3 (21.8 %), and 4 (7.0 %) had high probabilities of VA and Medicare use, but differed in their Medicare services used. For example, Veterans in class 3 received test strips exclusively through Medicare, while Veterans in class 4 were reliant on Medicare for medications. Living ≥ 40 miles from a VA predicted membership in classes 3 (OR 1.1, CI 1.06–1.15) and 4 (OR 1.11, CI 1.04–1.18), while Medicaid eligibility predicted membership in class 4 (OR 4.30, CI 4.10–4.51).

CONCLUSIONS

Veterans with diabetes can be grouped into four distinct classes of dual health system use, representing a novel way to characterize how patients use multiple services across healthcare systems. This classification has applications for identifying patients facing differential risk from care fragmentation.

     

Healthcare Costs Associated with Depression in Medically Ill Fee-for-Service Medicare Participants

OBJECTIVES: To examine the association between depression and healthcare costs in medically ill fee-for-service (FFS) Medicare recipients.
STUDY DESIGN: Observational analysis of Medicare claims data.
SETTING: Medicare Health Support (MHS) program at Green Ribbon Health.
PARTICIPANTS: Fourteen thousand nine hundred two participants with diabetes mellitus, congestive heart failure (CHF), or both.
MEASUREMENTS: This study examined participant data for a 12-month period before MHS enrollment (collected between November 2004 and August 2006). Twelve-month healthcare costs (based on Medicare claims) in 2,108 participants with International Classification of Diseases, Ninth Revision , claims diagnoses of depression, 1,081 participants with possible depression (positive depression screen on the two-item Patient Health Questionnaire or self reported antidepressant use), and 11,713 participants without depression were compared. Gamma regression models were used to adjust for demographic and clinical differences and nonnormal distribution of cost data.
RESULTS: Participants with depression had significantly higher total healthcare costs than those without ($20,046 vs $11,956; P <.01). Higher costs were observed in participants with depression in every cost category except specialty mental health care, which accounted for less than 1% of total healthcare costs. Participants with depression had higher costs in each quartile of increasing medical severity (measured using the Charlson Comorbidity Index). These differences remained statistically significant after adjusting for demographic and other clinical differences.
CONCLUSION: Depression is associated with significantly higher healthcare costs in FFS Medicare recipients with diabetes mellitus and CHF. Only a small proportion of the increased costs are spent on mental health specialty care.
