Mobile Technology Care Coordination of Long-Term Services and Support: Cluster Randomized Clinical Trial.

The purpose of the study was to assess whether the effects of a mobile predictive intervention used by Service Coordinators (SCs) reduce hospital utilization in a Medicaid Long-Term Services and Supports (LTSS) population in Baltimore city during a 5-month intervention. SC participants (n = 11) were recruited to treatment or control groups. LTSS clients (n = 420) followed their SC randomization assignment. Utilization data were obtained from the Maryland Chesapeake Regional Information System for our Patients (CRISP) Health Information Exchange (HIE) system and linked to service coordination records. Study groups were similar in age, gender, race, and years receiving LTSS. SCs' satisfaction with use of the mobile tool was surveyed. SC perceptions were neutral (mean scores ranged from 2.3 to 3.3 on a 5-point scale). No significant differences between groups were observed for all utilization metrics. The mobile technology software system used in this study did not improve health care utilization for a LTSS population needing ongoing clinical and social services coordinated care.

Digital assessment of falls risk, frailty, and mobility impairment using wearable sensors.

Falls are among the most frequent and costly population health issues, costing $50bn each year in the US. In current clinical practice, falls (and associated fall risk) are often self-reported after the "first fall", delaying primary prevention of falls and development of targeted fall prevention interventions. Current methods for assessing falls risk can be subjective, inaccurate, have low inter-rater reliability, and do not address factors contributing to falls (poor balance, gait speed, transfers, turning). 8521 participants (72.7 ± 12.0 years, 5392 female) from six countries were assessed using a digital falls risk assessment protocol. Data consisted of wearable sensor data captured during the Timed Up and Go (TUG) test along with self-reported questionnaire data on falls risk factors, applied to previously trained and validated classifier models. We found that 25.8% of patients reported a fall in the previous 12 months, of the 74.6% of participants that had not reported a fall, 21.5% were found to have a high predicted risk of falls. Overall 26.2% of patients were predicted to be at high risk of falls. 29.8% of participants were found to have slow walking speed, while 19.8% had high gait variability and 17.5% had problems with transfers. We report an observational study of results obtained from a novel digital fall risk assessment protocol. This protocol is intended to support the early identification of older adults at risk of falls and inform the creation of appropriate personalized interventions to prevent falls. A population-based approach to management of falls using objective measures of falls risk and mobility impairment, may help reduce unnecessary outpatient and emergency department utilization by improving risk prediction and stratification, driving more patients towards clinical and community-based falls prevention activities.

The Forgotten Middle: Many Middle-Income Seniors Will Have Insufficient Resources For Housing And Health Care.

As people age and require more assistance with daily living and health needs, a range of housing and care options is available. Over the past four decades the market for seniors housing and care-including assisted living and independent living communities-has greatly expanded to accommodate people with more complex needs. These settings provide housing in a community environment that often includes personal care assistance services. Unfortunately, these settings are often out of the financial reach of many of this country's eight million middle-income seniors (those ages seventy-five and older). The private seniors housing industry has generally focused on higher-income people instead. We project that by 2029 there will be 14.4 million middle-income seniors, 60 percent of whom will have mobility limitations and 20 percent of whom will have high health care and functional needs. While many of these seniors will likely need the level of care provided in seniors housing, we project that 54 percent of seniors will not have sufficient financial resources to pay for it. This gap suggests a role for public policy and the private sector in meeting future long-term care and housing needs for middle-income seniors.

A Randomized Controlled Trial of TELEmedicine for Patients with Inflammatory Bowel Disease (TELE-IBD).

INTRODUCTION: Telemedicine has shown promise in inflammatory bowel disease (IBD). The objective of this study was to compare disease activity and quality of life (QoL) in a 1-year randomized trial of IBD patients receiving telemedicine vs. standard care. METHODS: Patients with worsening symptoms in the prior 2 years were eligible for randomization to telemedicine (monitoring via texts EOW or weekly) or standard care. The primary outcomes were the differences in change in disease activity and QoL between the groups; change in healthcare utilization among groups was a secondary aim. RESULTS: 348 participants were enrolled (117 control group, 115 TELE-IBD EOW, and 116 TELE-IBD weekly). 259 (74.4%) completed the study. Age was 38.9 ± 12.3 years, 56.6% were women, 91.9% were Caucasian, 67.9% had Crohn's disease (CD) and 42.5% had active disease at baseline. In CD, all groups experienced a decrease in disease activity (control -5.2 ± 5.0 to 3.7 ± 3.6, TELE-IBD EOW 4.7 ± 4.1 to 4.2 ± 3.9, and TELE-IBD weekly 4.2 ± 4.2 to 3.2 ± 3.4, p < 0.0001 for each of the groups) In UC, only controls had a significant decrease in disease activity (control 2.9 ± 3.1 to 1.4 ± 1.4, p = 0.01, TELE-IBD EOW 2.7 ± 3.1 to 1.7 ± 1.9, p = 0.35, and TELE-IBD Weekly 2.5 ± 2.5 to 2.0 ± 1.8, p = 0.31). QoL increased in all groups; the increase was significant only in TELE-IBD EOW (control 168.1 ± 34.0 to 179.3 ± 28.2, p = 0.06, TELE-IBD EOW 172.3 ± 33.1 to 181.5 ± 28.2, p = 0.03, and TELE-IBD Weekly 172.3 ± 34.5 to 179.2 ± 32.8, p = 0.10). Unadjusted and adjusted changes in disease activity and QoL were not significantly different among groups. Healthcare utilization increased in all groups. TELE-IBD weekly were less likely to have IBD-related hospitalizations and more likely to have non-invasive diagnostic tests and electronic encounters compared to controls; both TELE-IBD groups had decreased non-IBD related hospitalizations and increased telephone calls compared to controls. DISCUSSION: Disease activity and QoL, although improved in all participants, were not improved further through use of the TELE-IBD system. TELE-IBD participants experienced a decrease in hospitalizations with an associated increase in non-invasive diagnostic tests, telephone calls and electronic encounters. Research is needed to determine if TELE-IBD can be improved through patient engagement and whether it can decrease healthcare utilization by replacing standard care.

Proximal Predictors of Long-Term Discontinuance with Noninsulin Antihyperglycemic Agents.

BACKGROUND: Noninsulin antihyperglycemic agents (NAAs) are the mainstay of treatment for type 2 diabetes, yet persistence in NAA use is suboptimal in many diabetes patients. Most of the research on NAA discontinuance has focused on sociodemographic characteristics and general health status, but such factors are inherently limited in explaining dynamic events such as discontinuance. OBJECTIVE: To assess the relative importance of static and proximal dynamic factors in explaining long-term NAA discontinuance among Medicare beneficiaries with diabetes. METHODS: Two sets of probability models were estimated to predict NAA discontinuance as a function of static variables (age, sex, race, original reason for Medicare entitlement, low-income subsidy and dual Medicare/Medicaid eligibility status, and disease burden) and 21 dynamic factors capturing month-by-month changes in drug use, health status, and use of medical services leading up to discontinuance (defined as month 0) and the previous 4 months (designated months -1 to -4) among 71,619 patients with diabetes enrolled in Medicare Part D plans in 2006-2008. RESULTS: Static variables explained just 1.2% of the variance in probability of NAA discontinuance compared with 14% for all variables combined. Key time-related predictors of NAA discontinuance included discontinuation with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs) and statins, hypoglycemia, NAA usage gaps, insulin use, and discharge from hospitals and skilled nursing facilities (SNFs). The strongest significant predictors (P < 0.05) of NAA discontinuance were discontinuation with statins and ACEIs/ARBs in month 0 (predicted probabilities of 37% and 34%, respectively). Other variables that significantly increased the probability of NAA discontinuance by 10% or more were hypoglycemia in month 0 (14%) and month -1 (17%), discontinuance with ACEIs/ARBs in months -1 (15%) and -2 (10%), discontinuance with statins in month -1 (13%), and insulin use in month 0 (12%). Experiencing a previous gap in NAA therapy was associated with higher likelihood of discontinuance if the gap occurred in month -2 (10%) or month -4 (6%), but a gap in therapy in month -1 actually reduced the likelihood of discontinuance by 13%. Discharge from a hospital or SNF was consistently associated with higher probabilities of NAA discontinuance ranging between 4% and 10%, with higher probabilities occurring closer to month 0. CONCLUSIONS: A cascade of dynamic changes preceding discontinuance with NAA therapy among Medicare Part D enrollees with diabetes was observed between 2006 and 2008. Understanding that lack of persistence in drug use is a dynamic rather than a static phenomenon opens up new avenues for investigating and ultimately improving adherence behavior in the elderly.

Assessment of an Expanded Functional Disability Scale for Older Adults With Diabetes.

Although prior literature has shown the plausibility of combining the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) items to form an expanded scale for measuring the degree of functional decline, this has not been shown in older adults with diabetes who are disproportionately affected by functional disability. Using the 2009 Medicare Current Beneficiary Survey data, we evaluated the factor structure of the pooled ADL and IADL items. Based on our study comprising 2,158 community-dwelling older adults (≥65 years) with diabetes, the unidimensional model exhibited good fit. Despite well-fitting indices, high correlations were observed between the latent constructs (>.70) of the multi-factor models, suggesting a lack of discriminant validity. These findings provide empirical support for a combined scale that can comprehensively and efficiently characterize the extent of functional disability in older adults with diabetes for research, risk adjustment, and evaluation in patient-centered medical homes.

TELEmedicine for Patients with Inflammatory Bowel Disease (TELE-IBD): Design and implementation of randomized clinical trial.

BACKGROUND: Inflammatory bowel diseases (IBD), comprised of ulcerative colitis and Crohn's disease, are chronic disorders characterized by worsening of symptoms followed by symptom-free periods. Symptoms have a profound negative impact on quality of life and are associated with increased health care utilization. Despite effective treatments, outcomes are suboptimal secondary to nonadherence, medication intolerance, inconsistent monitoring, poor patient knowledge and limited access to care. OBJECTIVES: Compare disease activity and quality of life over 1 year in a randomized trial of IBD patients receiving standard care versus telemedicine. METHODS: Patients evaluated at 3 IBD referral centers with worsening symptoms within the last 2 years are eligible for randomization to one of two interventions or standard care. The interventions consist of either every other week or weekly assessment of symptoms, side effects, weight and delivery of medication prompts and education via texts to the participant's mobile phone. Individualized alerts and action plans are created on a secure portal. Participants in the standard care group undergo routine and urgent follow-up visits and telephone calls. The primary outcomes group comparisons of changes in disease activity and quality of life scores from baseline to 6 and 12 months. CONCLUSIONS: Methods such as telemedicine are needed to improve monitoring, adherence, self-efficacy, and patient knowledge in IBD. If effective, telemedicine should decrease symptoms, improve quality of life, and decrease health care utilization. The burden associated with use of telemedicine for patients and providers needs to be assessed. The trial is ongoing and will be completed in July 2016.

The role of nursing home admission and dementia status on care for diabetes mellitus.

OBJECTIVES: To study the role of nursing home (NH) admission and dementia status on the provision of five procedures related to diabetes mellitus. DESIGN: Retrospective cohort study using data from a large prospective study in which an expert panel determined the prevalence of dementia. SETTING: Fifty-nine Maryland NHs. PARTICIPANTS: Three hundred ninety-nine new admission NH patients with diabetes mellitus. MEASUREMENTS: Medicare administrative claims records matched to the NH medical record data were used to measure procedures related to diabetes mellitus received in the year before NH admission and up to a year after admission (and before discharge). Procedures included glycosylated hemoglobin, fasting blood glucose, dilated eye examination, lipid profile, and serum creatinine. RESULTS: For all but dilated eye examinations, higher rates of procedures related to diabetes mellitus were seen in the year after NH admission than in the year before. Residents without dementia received more procedures than those with dementia, although this was somewhat attenuated after controlling for demographic, health, and healthcare utilization variables. Persons without dementia experience greater increases in procedure rates after admission than those with dementia. CONCLUSION: The structured environment of care provided by the NH may positively affect monitoring procedures provided to elderly persons with diabetes mellitus, especially those without dementia. Medical decisions related to the risks and benefits of intensive treatment for diabetes mellitus to patients of varying frailty and expected longevity may lead to lower rates of procedures for residents with dementia.

Commentary: male osteoporosis-policy gaps in prevention and treatment.

Osteoporosis is a disabling disease affecting 10 million Americans, leading to increased risk of fractures and poor functional ability. Although typically thought of as a women's disease, millions of men are diagnosed with osteoporosis or low bone mass, and the risk for osteoporotic fractures is increasing. To address undetected and untreated osteoporosis among men, public health education should be targeted to males. Insurance programs, including Medicare, should add the heel qualitative ultrasound (QUS) for age-eligible men with follow-up every 2 years. Policy changes should address funding of targeted education and prevention programs for aging males, including coverage of screening tests.

Discussion as a factor in racial disparity in advance directive completion at nursing home admission.

Studies have consistently shown racial disparities in advance directive completion for nursing home residents but have not examined whether this disparity is due to differences in interactions with healthcare providers. This study had two aims: to determine whether the racial disparity in advance directive completion by nursing home residents is related to differences in discussion of treatment restrictions with healthcare providers and to examine whether there is a racial disparity in perceptions of residents' significant others that additional discussions would be helpful. Participants were 2,171 white or black (16% of sample) residents newly admitted to 59 nursing homes. Data were collected from structured interviews with residents' significant others and review of nursing home charts. Questions included whether advance directives were completed, whether treatment restrictions were discussed with the resident or family, and whether more discussion would have been helpful. Frequencies according to race were determined for each question; P-values and logistic regression models were obtained. Black residents were less likely to have completed any advance directives (P<.001), and they (P<.001) and their family members (P<.001) were less likely than whites to have discussed treatment restrictions with healthcare providers. Logistic regression models indicated that disparity in treatment restrictions narrowed when these discussions occurred. Significant others of black residents were more likely than those of white residents to consider further discussion helpful (P<.001), especially with physicians. Racial disparity in treatment restrictions may be due in part to a difference in discussion with healthcare providers; increasing discussion may narrow this disparity.

Sensitivity of nursing home cost comparisons to method of dementia diagnosis ascertainment.

This study compared the association of differing methods of dementia ascertainment, derived from multiple sources, with nursing home (NH) estimates of prevalence of dementia, length of stay, and costs an understudied issue. Subjects were 2050 new admissions to 59 Maryland NHs, from 1992 to 1995 followed longitudinally for 2 years. Dementia was ascertained at admission from charts, Medicare claims, and expert panel. Overall 59.5% of the sample had some indicator of dementia. The expert panel found a higher prevalence of dementia (48.0%) than chart review (36.9%) or Medicare claims (38.6%). Dementia cases had lower relative average per patient monthly costs, but longer NH length of stay compared to nondementia cases across all methods. The prevalence of dementia varied widely by method of ascertainment, and there was only moderate agreement across methods. However, lower costs for dementia among NH admissions are a robust finding across these methods.

Nursing home characteristics related to medicare costs for residents with and without dementia.

OBJECTIVES: To evaluate the relationship of nursing home characteristics to Medicare costs overall and by dementia status. DESIGN: New admissions followed for 2 years. Setting. Random stratified sample of 55 Maryland nursing homes. PARTICIPANTS: Sample of 1257 residents. MEASURES: Records, interview, and observation. RESULTS: Medicare costs were lower in facilities that have a better environmental quality, hospice beds, and more food service workers; costs were higher in hospital-based facilities and those that have a higher Medicaid case mix, X-ray, and some specified types of staff. Across all characteristics, costs for residents with dementia were consistently two-thirds the cost of other residents. DISCUSSION: In terms of dementia status, resident characteristics drive Medicare costs, as opposed to facility characteristics. Using alternative residential settings for individuals with dementia may increase Medicare costs of nursing home residents and Medicare costs of residents with dementia who are cared for in settings less able to attend to medical needs.

Variation in antidiabetic medication intensity among Medicare beneficiaries with diabetes mellitus.

BACKGROUND: Recent guidelines for treating older patients with diabetes mellitus (DM) and significant disease burden place less emphasis on glycemic control and stress the potential harms that may arise from adherence to strict regimens with antidiabetic medications. However, there are few empirical benchmarks against which clinicians can compare their prescribing practices for patients who have DM and varying levels of comorbidity. OBJECTIVE: The current study had 2 goals: (1) to provide national estimates showing how the intensity of antidiabetic medication regimens for Medicare beneficiaries with DM varies by level of medical spending (a proxy for overall disease burden); and (2) to identify potential predictive factors associated with the observed differences. METHODS: This study analyzed 2002 Medicare Current Beneficiary Survey (MCBS) data to benchmark intensity of antidiabetic medication regimens for Medicare beneficiaries with DM arrayed by decile of cumulative medical care spending. The study involved 3 steps: (1) stratification of the study population into 10 mutually exclusive deciles by cumulative all-source annual medical spending; (2) assessment of the unconditional association between decile assignment and intensity of antidiabetic medication use; and (3) identification of mediating factors that differentially explain medication intensity across the spectrum of disease burden. We evaluated 3 outcomes: (1) prevalence of any antidiabetic agent in 2002; (2) annual utilization rates for 5 different classes of oral hypoglycemic agents (sulfonylurea, metformin, thiazolidinedione, alpha-glucosidase inhibitors, and meglitinides) plus insulins; and (3) counts of annual prescription fills. RESULTS: The final study sample comprised 1956 Medicare beneficiaries representing 23.1% of the MCBS sample after exclusions. We found a pronounced inverted U-shaped pattern in intensity of antidiabetic treatment. Compared with individuals in the group with the highest prevalence of antidiabetic use (decile 7), the unadjusted treatment odds ratios were 0.40 in decile 1 (95% CI, 0.26-0.60) and 0.54 in decile 10 (95% CI, 0.36-0.81). We found similar patterns in the complexity of drug regimens and numbers of antidiabetic prescriptions filled among users. Controlling for disease severity and other factors eliminated the inverted U-shaped pattern among higher cost beneficiaries but not for those in the lower spending deciles. CONCLUSIONS: This national study found that high-cost Medicare beneficiaries with DM received substantially less intensive antidiabetic regimens compared with those incurring more modest medical expenditures in 2002. Longitudinal analysis is necessary to determine whether this finding indicates suboptimal therapy or has a more benign explanation. However, the magnitude of the association warrants the attention of clinicians who treat elderly and disabled diabetic patients with high disease burden.

Mortality and adverse health events in newly admitted nursing home residents with and without dementia.

OBJECTIVES: To evaluate the association between dementia and mortality, adverse health events, and discharge disposition of newly admitted nursing home residents. It was hypothesized that residents with dementia would die at a higher rate and develop more adverse health events (e.g., infections, fevers, pressure ulcers, falls) than residents without dementia because of communication and self-care difficulties. DESIGN: An expert clinician panel diagnosed an admission cohort from a stratified random sample of 59 Maryland nursing homes, between 1992 and 1995. The cohort was followed for up to 2 years or until discharge. SETTING: Fifty-nine Maryland nursing homes. PARTICIPANTS: Two thousand one hundred fifty-three newly admitted residents aged 65 and older not having resided in a nursing home for 8 or more days in the previous year. MEASUREMENTS: Mortality, infection, fever, pressure ulcers, fractures, and discharge home. RESULTS: Residents with dementia had significantly lower overall rates of infection (relative risk (RR)=0.77, 95% confidence interval (CI)=0.70-0.85) and mortality (RR=0.61, 95% CI=0.53-0.71) than those without dementia, whereas rates of fever, pressure ulcers, and fractures were similar for the two groups. These results persisted when rates were adjusted for demographic characteristics, comorbid conditions, and functional status. During the first 90 days of the nursing home stay, residents with dementia had significantly lower rates of mortality if not admitted for rehabilitative care under a Medicare qualifying stay (RR=0.25, 95% CI=0.14-0.45), were less often discharged home (RR=0.33, 95% CI=0.28-0.38), and tended to have lower fever rates (RR=0.78, 95% CI=0.63-0.96) than residents without dementia. CONCLUSION: Newly admitted nursing home residents with dementia have a profile of health events that is distinct from that of residents without dementia, indicating that the two groups have different long-term care needs. Results suggest that further investigation of whether residents with dementia can be well managed in alternative residential settings would be valuable.

Medicare cost differences between nursing home patients admitted with and without dementia.

PURPOSE: Our objective in this study was to compare Medicare costs of treating older adults with and without dementia in nursing home settings. DESIGN AND METHODS: An expert panel established the dementia status of a stratified random sample of newly admitted residents in 59 Maryland nursing homes between 1992 and 1995. Medicare expenditures per-person month (PPM) were compared for 640 residents diagnosed with dementia and 636 with no dementia for 1 year preadmission and 2 years postadmission. Multivariate analysis with generalized estimating equations was used to identify the source of Medicare cost differentials between the two groups. RESULTS: Medicare expenditures peaked in the month immediately preceding admission and dropped to preadmission levels by the third month in a nursing home. Adjusted PPM costs postadmission for the dementia group as a whole were 79% (p < .001) of the Medicare costs of treating residents without dementia. For the subgroup of residents admitted without a Medicare qualified stay (MQS), those with dementia had Medicare costs of just 63% (p < .001) of those without dementia. Overall Medicare costs PPM were insignificantly different between the two groups admitted with a MQS. IMPLICATIONS: Whether nursing home residents are admitted with a MQS is the single most important factor in assessing treatment cost differentials between residents admitted with and without dementia. Failure to consider this factor may lead researchers and policy makers to misdirect their attention from the true source of the differential-dementia patients admitted without a qualifying stay.
