National Geriatric Network Rapidly Addresses Trainee Telehealth Needs in Response to COVID-19

BACKGROUND/OBJECTIVES

Coronavirus disease 2019 (COVID‐19) has pushed many geriatric healthcare providers to attempt video visits for the first time. Although the Veterans Health Administration (VA) is a pioneer in telemedicine, rapid shifts to nearly exclusive use of telehealth for healthcare delivery and changes regarding trainee engagement in telehealth served as the impetus for rapidly assessing telehealth training needs.

DESIGN

National needs assessment (online survey) of associated health trainees and medical fellows affiliated with Geriatric Research Education and Clinical Centers (GRECCs).

SETTING

National GRECC network ‐‐ 20 VA centers of excellence focused on supporting Veterans as they age. Each GRECC is affiliated with a school of medicine at a major university.

PARTICIPANTS

Trainees (n = 89) representing 12 disciplines.

RESULTS

Two‐thirds of participants had received some telehealth training. However, most had never done a video‐to‐home visit, and, regardless of telehealth experience, they reported low confidence. Based on open‐ended questions exploring training needs, educational resources were rapidly developed and disseminated.

INTERVENTION

Within 1 week of the assessment, a nuts‐and‐bolts guide regarding remote access, technology requirements, video‐conferencing platforms, and managing emergencies was sent to the national network of GRECC associate directors for education for dissemination among discipline‐specific training directors at their sites. This resource was subsequently submitted to the national VA COVID Strong Practices SharePoint site. An interdisciplinary team of geriatric specialists with extensive video‐to‐home experience also organized a national webinar that peaked at just over 700 participants. GRECC Connect, a network of geriatric specialty teams funded to improve care access for rural older veterans using telehealth and associated health training programs at each GRECC facilitated rapid development and dissemination of both resources.

CONCLUSION

We quickly identified and responded to telehealth training needs of geriatrics trainees to optimize care for rural older adults as part of a rapid response to COVID‐19. Although the webinar and nuts‐and‐bolts resources were developed within the VA context, they have demonstrated high demand and broader applicability. Results should continue to inform curriculum development efforts to address telehealth training gaps within and outside the VA.

Piezoelectric modulation of broadband photoresponse of flexible tellurium nanomesh photodetectors

Flexible photodetector shows great potential applications in intelligent wearable devices, health monitoring, and biological sensing. In this work, single crystal β-tellurium nanowires were grown on flexible muscovite by molecular beam epitaxy, constructing high-density ordered nanomesh structure. The prepared photodetectors based on tellurium nanomesh exhibit excellent mechanical flexibility, fast response in a broad range from ultraviolet to near-infrared, and good photosensitivity. We found that the flexible photodetectors with Shottky contact drastically suppressed dark current, while the response speed was lowered in comparison to the devices with ohmic contact, as holes would take a long time to tunnel through the Shottky barrier between metal and p-type Te. Moreover, the photoresponse of flexible Shottky photodetectors can be modulated by piezoelectricity of tellurium, and pronounced photocurrent increase after bending many times. Under external stress, polarization charges could tune Shottky barrier height of the metal/tellurium, resulting in variation of photocurrent. This research not only explores the broadband photoresponse and piezoelectric effect of tellurium nanomesh, but also promotes the integration and development of broadband flexible optoelectronic devices.

A MULTI-SITE PROGRAM TO PROVIDE GERIATRICS TELECONSULTATION TO OLDER RURAL VETERANS (GRECC CONNECT)

Older Veterans living in rural areas often do not have access to geriatrics team care; rural frontline providers and teams may need support to address the needs of older adults with complex chronic conditions. GRECC Connect aims to link up geriatric teams at Geriatric Research, Education and Clinical Centers (GRECCs) and rural clinics to provide geriatric consultation remotely through clinical video telehealth (CVT) and other means. GRECC Connect is established in twelve GRECCs across the country with links to rural clinics in their catchment area; consultations led to identification and meeting of care needs of older adults with complex conditions, improving medication use and reducing older adults’ need for travel to long distances for consultation. In this presentation, we review the experience of establishing connections with rural clinics, impact on older adult care and adaptations needed to address local needs and contexts.

EVALUATION OF THE RESCUE PROGRAM FOR REDUCING STROKE CAREGIVER STRESS AND IMPROVING PROBLEM-SOLVING ABILITIES

Research shows that caregiver interventions that combine problem-solving with psycho-education are the most effective for addressing stroke caregiver concerns. The Resources and Education for Stroke Caregivers’ Understanding and Empowerment (RESCUE) program, designed to reduce caregiver stress, depression, and burden, developed as a result of this evidence. A 4-week telephone and web-based clinical demonstration project led by registered nurses was established as part of the VHA Office of Geriatrics and Extended Care’s Non-Institutional Long Term Care Initiative. The goals of this clinical demonstration were to improve problem-solving skills and provide individualized support for stroke caregivers. A single-group pre and post-test design was used and 72 caregivers of veterans with stroke completed the intervention; qualitative and quantitative methods were used for evaluation. The outcome variables were caregiver depressive symptoms, problem-solving abilities, burden, health-related quality of life and care recipient functional abilities. Post-tests were conducted 2-6 weeks after the intervention. The evaluation found that there were statistically-significant decreases in caregiver depressive symptoms and burden from pre- to post-test assessments. Caregivers’ negative problem orientation significantly decreased. The other components of problem-solving abilities did not change. Qualitative data revealed how the program increased caregivers’ confidence in problem-solving which led to new strategies to relieve stress. Interviews also revealed how the intervention affected caregivers in unexpected ways, such as improved intimate relationships and new perspectives on caregiving. The preliminary effectiveness and barriers and facilitators of implementing a stroke caregiver program will be discussed.

FEASIBILITY OF MOBILE HEALTH FOR LOW-INCOME MINORITY HISPANIC PATIENTS WITH A STROKE

Stroke is a leading cause of death and functional impairment that disproportionately impacts Hispanics. Several studies have supported the feasibility of mobile health interventions (mHealth) to provide health monitoring and patient education for improving chronic disease management, but none have focused on Latino stroke patients. The Hispanic Secondary Stroke Prevention Initiative is a randomized study of 200 stroke patients designed to evaluate the impact of a 12-month multi-modal Community Health Worker (CHW) and mHealth intervention on blood pressure control. Eligible participants were Latinos who experienced a mild-moderate stroke within the last five years. The CHW component included home visits, telephone calls, and daily text messages to obtain home blood pressure readings and provide patient navigation and health education. Feasibility was defined as the proportion of patients that responded to at least half the messages. Pre-post paired t-tests assessed improvements in question accuracy while correlation coefficients highlighted improvements in response rates. Among the 65 participants randomized to the intervention, the response rate was as follows: 37% - >50% response, 21% - 25-50%, 19% - 10-25%, and 23% - <10%, This finding suggests that mHealth interventions may be challenging in this population. However, the proportion of questions answered correctly increased from 63% to 84% in the intervention period’s last two months (p<0.05). There was a positive correlation between increased response rates and response accuracy to patient education assessments (r=0.82, p<0.05). These improvements in health knowledge suggest that a subset of patients may benefit from mHealth interventions, and the benefit correlates with use.

SELF-GLUCOSE MONITORING AND HYPOGLYCEMIA RISK IN OLDER RURAL VETERANS WITH TYPE 2 DIABETES

Hypoglycemia evaluation is expected in every encounter with diabetic patients. However, self-monitoring and self-management may not be complete at home, and limited by geriatric syndromes. Furthermore, hypoglycemia risk increases with age, and rurality may limit access to frequent monitoring. We identified 112 rural veterans with high hypoglycemia risk, using the local medication database (sulfonylureas and insulin), combined with age and glycated hemoglobin (HbA1c). Statistical analyses were conduct using SAS 9.4 (Cary, NC). We used Chi-square, Fisher’s, One-way ANOVA for baseline variables, and a multivariate logistic regression model to assess the association of hypoglycemia and risk factors, including age, HbA1c%, self-monitoring, and knowledge. Hypoglycemia was reported in 30.4% of cases, of whom the majority were younger than those not reporting hypoglycemia (72.0±4.3 vs 75.0±6.5 years, p=.015). Baseline HbA1c% was higher in cases with hypoglycemia compared to those without (7.7±1.6% versus 7.3±1.2%, not statistically significant). There were no significant differences between pharmacologic regimens, self-monitoring, and general knowledge. Veterans who knew hypoglycemia symptoms were 6 times more likely to reported hypoglycemia, compared with veterans who did not know any symptoms. We contacted primary care teams (PCT) for whom medications were adjusted. Hypoglycemia risk is high in the older population, and telemedicine programs can support primary care teams to improve management of their patients. Poor symptom knowledge needs to be addressed, while considering special attention for hypoglycemia unawareness in the oldest age group. We are implementing a project using continuous glucose monitoring in this high-risk population.

SOCIAL ISOLATION AND MENTAL HEALTH CHALLENGES AMONG HIGH-NEEDS VETERANS

Using predictive analytic modeling, the Veterans Affairs has identified vulnerable Veterans, labeled as High Need High Risk (HNHR), as those who need greater services and support. To better understand their need gaps, we assessed function, mobility, mood, and caregiver status using a mailed needs assessment questionnaire to 1112 HNHR Veterans. Among the 341(30.7%) respondents, they were primarily 274(80.4%) Non-Hispanics; 210(61.6%) Whites, and 119(34.9%) Black or African Americans; average age was 69.5±9.6 years old; 310(90.4%) had ≥high school education. The average Barthel ADL score was 81.5±22.8 and average Lawton IADL score was 5.8±2.2. Walking or balance issues were present among 260(75.8%), 227(66.2%) said they use an assistive device, and 167(48.7%) had suffered ≥1 fall, 43(12.5%). Regarding depression, 117(34.3%) screened positive (PHQ2 score≥3). These were significantly younger (66.7±9.1) than those who did not (70.8±9.3, p≤0.01). They were also significantly lower functioning (5.37±2.1 vs.6.38±2 Lawton IADL score, p≤0.01), more dependent (77.8±23.1 vs 86±19.2 Barthel ADL score, p≤0.01). We also observed significant differences in their telephone contact with family (never to once/week) [35(29.9%) vs. 27(13.4%), (p≤0.01)]; in meeting with friends or relatives ≥3times a week [12(10.3%) vs. 69(34.3%), (p≤0.01)]; and in likelihood of attending meetings with clubs or other organizations [94(80.3%) vs. 138(68.7%), p=0.040]. Detecting depression is a priority among HNHR Veterans. There is an urgent need to devise viable strategies to offer interventions that incorporate mental health needs and reduce social isolation, potentially addressing mobility, function, and transportation.

GREATER HYPOGLYCEMIA UNAWARENESS IN OLDER COMPARED TO YOUNGER RURAL VETERANS WITH TYPE 2 DIABETES

Hypoglycemia is of great concern in older patients, especially when complicated with multimorbidity and geriatric syndromes. We implemented a telemedicine model to address hypoglycemia knowledge, risk factors, incidence and comanagement with their primary care teams (PCT). We identified 166 consecutive rural veterans with high hypoglycemia risk, based on a local medication database (sulfonylureas and insulin), age, and recent glycated hemoglobin A1c (HbA1c). We conducted a telephone medication reconciliation and survey assessing glucose self-monitoring (GSM), hypoglycemia knowledge and symptoms. Variables were tested using chi-square, Fisher’s, and one-way ANOVA. Multivariable logistic regression model was built to assess the association of hypoglycemia and age group, adjusted with treatment, HbA1c%, self-monitoring, and knowledge. There were 54 veterans aged <65 (younger), and 112 veterans aged ≥65 years (older). Average HbA1c was higher in younger than older (8.20±1.96 vs 7.43±1.34%, p=.003). There was no difference in treatment regimens, but the older had greater GSM (p=.028) and lower hypoglycemia symptom knowledge (p=.026). Symptomatic hypoglycemia was greater in younger versus older (50.0% vs 30.4%, p=0.014). Recent (past-2-weeks) hypoglycemic events were more frequent in younger than older (24.1 vs 1.79%, p<.001). Regression analyses showed that younger veterans were more likely to have hypoglycemia (OD=2.37, 95% CI 1.11-5.04). Our results indicate a great need to evaluate older adults with high hypoglycemia risk, in whom we observed less reports of hypoglycemia albeit with similar regimens and lower HbA1c. We suspect greater hypoglycemia unawareness, thus we are implementing a project using continuous glucose monitoring in this high-risk population.

AGE- AND ETHNICITY-RELATED DISPARITIES IN TECHNOLOGY USE AMONG HIGH-RISK VETERANS

Using predictive analytic modelling, the Veterans Affairs has identified Veterans considered to be High Need High Risk (HNHR) requiring increased support. This pilot study sent needs assessment questionnaires to 1112 HNHR Veterans to better understand gaps regarding technology use, access, physical function, and mobility. There were 341(30.7%) respondents: 270(80.4%) Non-Hispanic, 64(18.8%) Hispanic/Latino; 210(61.6%) White, 119(34.9%) Black/African Americans; and 310(90.4%) had ≥high school education. Average Barthel(ADL) score was 81.5±22.8 and Lawton(IADL) score was 5.8±2.2. Younger Veterans (age<70) were more likely able to use Internet ((117(65%) vs 74(46%)),(p≤0.01) and email (106(58.9%) vs 67(41.6%),( p≤0.01). They were also more likely enrolled in MyHealtheVet (87(48.3%) vs 58(36%),(p=0.043). Secure messaging was used by 62(34.3%) younger and 37(23%) older Veterans,(p=0.026). More higher functioning Veterans (140(55.1%)) used email than lower functioning (33(37.9%)),(p=0.018). Among higher functioning Veterans, 148(58.3%) were willing to use videoconference for care coordination and 116(45.7%) owned a smartphone or computer with camera for this; more than lower functioning Veterans (33(37.9%) and 28(32.2%)), (p≤0.01 for both). Less dependent Veterans preferred to be contacted via cellphone (88(62.4%)) or Internet (10(7.1%)) compared to the more dependent (96(48%) and 6(3%)) respectively (p=0.01). Only 71(44.1%) of older Veterans were willing to use videoconference (p≤0.01) and 54(33.5%) owned a smartphone or computer with camera,(p≤0.01). There are significant variations in technology use by age and ethnicity. However, although there are differences by functional ability, a significant number of disabled veterans are willing and able to use technology, and this may provide a way to address access barriers in this population.

A DECADE OF STROKE CAREGIVER RESEARCH: THE RESCUE CREST STUDY

Stroke caregivers need education and support to care for suddenly disabled family members. To address this need, we are conducting a nurse-led intervention, called RESCUE CREST, to teach caregivers problem-solving skills using an educational website and an online messaging center. In our first, preliminary study, we pre-tested an investigator-created, senior-friendly website called RESCUE (Resources and Education for Stroke Caregivers’ Understanding and Empowerment) using focus groups and interviews with clinicians and caregivers. We refined the website based on additional surveys, a cognitive usability study, and Webtrends analysis. In the second study, we used a single-group pre- and post-test design to evaluate the content and outcomes of the problem-solving intervention. Third, we conducted a four-arm RCT (4-week intervention, 8-week intervention, attention control, standard care) to refine our methods. We will describe the lessons learned and results of our 10 years of stroke caregiver research that provide background for the RESCUE CREST study.

GRECC Connect: Geriatrics Telehealth to Empower Health Care Providers and Improve Management of Older Veterans in Rural Communities

A telehealth program supports meaningful partnerships between urban geriatric specialists and rural health care providers to facilitate increased access to specialty care.

A Patient Portal Intervention for Menopause Knowledge and Shared Decision-Making

Background: Menopause is a time often fraught with changes and symptoms, which may require difficult choices and decision-making. During this period, women would benefit from a better understanding and in-depth discussions with providers regarding menopause, associated conditions, and appropriate therapy. Patient portals offer a potential means to improve knowledge and shared decision-making (SDM) about menopause. Materials and Methods: This protocol article explores the feasibility of using the secure messaging (SM) function of the Veterans Affairs (VA) Patient Portal, "My HealtheVet" to implement an educational intervention and measure its impact on knowledge and SDM in the management of menopause. Results: This is a quality improvement pilot study in which women veterans of menopausal age in the Miami VA are offered an educational intervention via a patient portal, while women veterans in two neighboring VA facilities are not. Intervention participants receive weekly SMs with information on menopause symptoms, and treatment. After 6-months, all participants are surveyed on menopause knowledge, SDM, and satisfaction with the program. Conclusion: This study is among the first to assess the impact of an innovative patient portal intervention to improve knowledge and SDM between patients and providers regarding menopause. If successful, our program will add to the "meaningful use" of patient portals and offer a scalable and timely resource for SDM about menopause.

A commentary on methodological issues in stroke caregiver research: lessons learned from three RESCUE intervention studies

Stroke caregivers represent a distinct population and require unique considerations when conducting intervention research. Unfortunately, there are few published recommendations for conducting intervention trials with stroke caregivers. Thus, the goal of this paper is to provide foundational guidance for stroke caregiving researchers. We describe lessons learned from three trials of the RESCUE intervention to illustrate methodological issues in stroke caregiver research. We identify challenges encountered while conducting a clinical demonstration project, pilot study, and multi-site randomized controlled trial of a problem-solving and skills-building stroke caregiver intervention. We use our research experiences to exemplify or enhance understanding of each issue and describe the strategies we employed to overcome these obstacles. We present issues related to and recommendations for study design, theoretical frameworks, eligibility criteria, recruitment and retention, human subjects protection, intervention design, treatment fidelity, outcome measures, and qualitative methods. Identifying approaches to circumvent methodological challenges can help advance research on and implementation of stroke caregiver programs.

Hispanic Secondary Stroke Prevention Initiative Design: Study Protocol and Rationale for a Randomized Controlled Trial

Background

Hispanic-Latino populations face a disproportionate stroke burden and are less likely to have sufficient control over stroke risk factors in comparison with other ethnic populations. A promising approach to improving chronic health outcomes has been the use of community health workers (CHWs).

Objective

The objective of this randomized controlled trial is to evaluate the effectiveness of a CHW intervention among Latino patients at risk of recurrent stroke.

Methods

The Hispanic Secondary Stroke Prevention Initiative (HiSSPI) is a randomized clinical trial of 300 Latino participants from South Florida who have experienced a stroke within the last 5 years. Participants randomized into the CHW intervention arm receive health education and assistance with health care navigation and social services through home visits and phone calls. The intervention also includes a mHealth component in which participants also receive daily text messages (short message service). The primary outcome is change in systolic blood pressure at 12 months. Other secondary outcomes include changes in low-density lipoprotein, glycated hemoglobin, and medication adherence.

Results

Study enrollment began in 2015 and will be completed by the end of 2018. The first results are expected to be submitted for publication in 2020.

Conclusions

HiSSPI is one of the first randomized controlled trials to examine CHW-facilitated stroke prevention and will provide rigorous evidence on the impact of CHWs on secondary stroke risk factors among Latino individuals who have had a stroke.

Association of the CAN score with the FRAIL scale in community dwelling older adults

BACKGROUND

Frailty is a state of vulnerability to stressors which results in higher morbidity, mortality and healthcare utilization. The FRAIL scale is used as a validated screening for frailty. The Care Assessment Need (CAN) score is automatically generated from electronic health record data using a statistical model that includes data elements similar to the deficit accumulation model for frailty and predicts risk for hospitalization and/or mortality.

AIM

To determine the correlation of the CAN score with the FRAIL scale.

METHODS

A cross-sectional study of 503 community-dwelling older adults. We compared the FRAIL scale with the CAN score.

RESULTS

The CAN score was significantly different between robust, prefrail and frail. Post hoc analysis revealed significant increases in scores from robust to prefrail and frail groups, in that order. The CAN score and FRAIL scale showed a correlation.

CONCLUSIONS

The CAN score show a moderate positive association with the FRAIL scale.

The Promise of Electronic Health Records to Promote Shared Decision Making: A Narrative Review and a Look Ahead

BACKGROUND

Shared decision making (SDM) involves the sharing of best available evidence between patients and providers in the face of difficult decisions. We examine outcomes that occur when electronic health records (EHRs) are purposefully used with the goal of improving SDM and detail which EHR functions can benefit SDM.

METHODS

A systematic search of PubMed yielded 1369 articles. Studies were included only if they used EHR interventions to support SDM and included results that showed impact on SDM. Articles were excluded if they did not measure the impact of the intervention on SDM or did not discuss how SDM had been supported by the EHR.

RESULTS

Five studies demonstrated improved clinical outcomes, positive lifestyle behavior changes, more deliberation from patients regarding use of imaging, and less decisional conflict about medication use among patients with use of EHRs aiding SDM.

DISCUSSION

Few EHRs have integrated SDM, and even fewer evaluations of these exist. EHRs have potential in supporting providers during all steps of SDM. The promise of EHRs to support SDM has yet to be fully exploited.

Diabetes Treatment in the Elderly: Incorporating Geriatrics, Technology, and Functional Medicine

PURPOSE OF REVIEW

The current approach to diabetes in the elderly incorporates components from the comprehensive geriatric approach. The most updated guidelines from the American Diabetes Association reflect influence from the consensus made in 2012 with the American Geriatrics Society. Notably, the framework included the evaluation for geriatric syndromes (falls and urinary incontinence), functional and cognitive abilities. The goal for this review is to provide an updated summary of treatment strategies for community-dwelling older adults. We identified the need to expand our approach by addressing innovative approaches and scientific concepts from telemedicine, functional medicine, and geriatrics.

RECENT FINDINGS

Findings on cardiovascular protection with sodium-glucose co-transporter 2 inhibitors (SGLT-2i) and some glucagon-like peptide 1 receptor agonists (GLP-1RA) support their use for older patients with diabetes. However, careful consideration for agent selection must incorporate the presence of geriatric issues, such as geriatric syndromes, or functional and cognitive decline, as they could increase the risk and impact adverse reactions. Telemedicine interventions can improve communication and connection between older patients and their providers, and improve glycemic control. Functional medicine concepts can offer additional adjuvant strategies to support the therapeutic interventions and management of diabetes in the elderly. A systematic review confirmed the efficacy and safety of metformin as first-line therapy of type 2 diabetes in the older adult, but multiple reports highlighted the risk for vitamin B12 deficiency. Randomized controlled trials showed the efficacy and safety of antihyperglycemic agents in the elderly, including some with longer duration and lesser risk for hypoglycemia. Randomized clinical trials showed cardiovascular protection with SGLT-2i (empagliflozin, canagliflozin) and GLP-1RA (liraglutide, semaglutide). The most current guidelines recommend addressing for geriatric syndromes, physical and cognitive function in the elderly, in order to individualize targets and therapeutic strategies. Clinicians managing diabetes in the elderly can play a major role for the early detection and evaluation of geriatric issues in their patients. Telemedicine interventions improve glycemic control, and certain functional medicine strategies could be adjuvant interventions to reduce inflammation and stress, but more studies focused on the elderly population are needed.

Validation of an automatically generated screening score for frailty: the care assessment need (CAN) score

BACKGROUND

Frailty is a state of vulnerability to stressors that is prevalent in older adults and is associated with higher morbidity, mortality and healthcare utilization. Multiple instruments are used to measure frailty; most are time-consuming. The Care Assessment Need (CAN) score is automatically generated from electronic health record data using a statistical model. The methodology for calculation of the CAN score is consistent with the deficit accumulation model of frailty. At a 95 percentile, the CAN score is a predictor of hospitalization and mortality in Veteran populations. The purpose of this study was to validate the CAN score as a screening tool for frailty in primary care.

METHODS

This is a cross-sectional, validation study compared the CAN score with a 40-item Frailty Index reference standard based on a comprehensive geriatric assessment. We included community-dwelling male patients over age 65 from an outpatient geriatric medicine clinic. We calculated the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of the CAN score.

RESULTS

184 patients over age 65 were included in the study: 97.3% male, 64.2% White, 80.9% non-Hispanic. The CGA-based Frailty Index defined 14.1% as robust, 53.3% as prefrail and 32.6% as frail. For the frail, statistical analysis demonstrated that a CAN score of 55 provides sensitivity, specificity, PPV and NPV of 91.67, 40.32, 42.64 and 90.91% respectively whereas at a score of 95 the sensitivity, specificity, PPV and NPV were 43.33, 88.81, 63.41, 77.78% respectively. Area under the receiver operating characteristics curve was 0.736 (95% CI = .661-.811).

CONCLUSION

CAN score is a potential screening tool for frailty among older adults; it is generated automatically and provides acceptable diagnostic accuracy. Hence, the CAN score may be a useful tool to primary care providers for detection of frailty in their patient panels.

Mobile Technologies for Managing Heart Failure: A Systematic Review and Meta-analysis

BACKGROUND

Randomized clinical trials (RCTs) conducted among heart failure (HF) patients have reported that mobile technologies can improve HF-related outcomes. Our aim was to conduct a meta-analysis to evaluate m-Health's impact on healthcare services utilization, mortality, and cost.

METHODS

We searched MEDLINE, Cochrane, CINAHL, and EMBASE for studies published between 1966 and May-2017. We included studies that compared the use of m-Health in HF patients to usual care. m-Health is defined as the use of mobile computing and communication technologies to record and transmit data. The outcomes were HF-related and all-cause hospital days, cost, admissions, and mortality.

RESULTS

Our search strategy resulted in 1,494 articles. We included 10 RCTs and 1 quasi-experimental study, which represented 3,109 patients in North America and Europe. Patient average age range was 53-80 years, New York Heart Association (NYHA) class III, and Left Ventricular Ejection Fraction <50%. Patients were mostly monitored daily and followed for an average of 6 months. A reduction was seen in HF-related hospital days. Nonsignificant reductions were seen in HF-related cost, admissions, and mortality and total mortality. We found no significant differences for all-cause hospital days and admissions, and an increase in total cost.

CONCLUSIONS

m-Health reduced HF-related hospital days, showed reduction trends in total mortality and HF-related admissions, mortality and cost, and increased total costs related to more clinic visits and implementation of new technologies. More studies reporting consistent quality outcomes are warranted to give conclusive information about the effectiveness and cost-effectiveness of m-Health interventions for HF.

Systematic review with meta-analysis: effectiveness and tolerability of interferon-free direct-acting antiviral regimens for chronic hepatitis C genotype 1 in routine clinical practice in Asia

BACKGROUND

Direct-acting antiviral (DAA) regimens have shown high efficacy and tolerability for patients with HCV genotype 1/1b (GT1/1b) in clinical trials. However, robust real-world evidence of interferon (IFN)-free DAA treatment for HCV GT1-infected patients in Asia is still lacking.

AIM

To systematically review and meta-analyse the effectiveness and tolerability of IFN-free DAA therapy for HCV GT1 infection in Asia.

METHODS

We included studies that enrolled adult patients with HCV GT1 infection in routine clinical practice in Asia, using IFN-free DAA regimens, and reported sustained virological response (SVR) after 12/24 weeks end-of-treatment by 31 May 2017. The pooled SVR rates were computed with a random-effects model. Subgroup analysis and meta-regression as previously registered in PROSPERO were performed to determine how pre-planned variables might have affected the pooled estimates.

RESULTS

We included 41 studies from eight countries and regions, comprising of 8574 individuals. The pooled SVR rates for GT1 were 89.9% (95% CI 88.6-91.1, I²  = 55.1%) with daclatasvir/asunaprevir (DCV/ASV) and 98.1% (95% CI 97.0-99.0, I²  = 41.0%) with ledipasvir/sofosbuvir ± ribavirin (LDV/SOF ± RBV). Baseline cirrhosis but not prior treatment history and age, attenuated the effectiveness of both regimens. Baseline resistance associated substitutions (RASs) severely attenuated SVR of DCV/ASV (65.4% vs 94.3%, P < 0.001) and only minimally with LDV/SOF ± RBV (94.5% vs 99.2%, P = 0.003). Patients with renal dysfunction treated with DCV/ASV showed a higher SVR rate (93.9% vs 89.8%, P = 0.046). Patients with hepatocellular carcinoma (HCC) LDV/SOF ± RBV achieved a lower SVR than those without HCC (94.1% vs 98.7%, P = 0.001).

CONCLUSION

All oral DAA treatment of HCV GT1 resulted in high cure rates in Asian patients in routine clinical practice setting including elderly patients and those with end-stage renal disease.
