The Promoting Effective Advance Care for Elders (PEACE) Randomized Pilot Study: Theoretical Framework and Study Design

Care models for individuals with chronic multimorbidity: lessons for low- and middle-income countries

BACKGROUND

Patients with multiple long-term conditions requires understanding the existing care models to address their complex and multifaceted health needs. However, current literature lacks a comprehensive overview of the essential components, impacts, challenges, and facilitators of these care models, prompting this scoping review.

METHODS

A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis Extension for Scoping Reviews guideline. Our search encompassed articles from PubMed, Web of Science, EMBASE, SCOPUS, and Google Scholar. The World Health Organization's health system framework was utilized to synthesis the findings. This framework comprises six building blocks (service delivery, health workforce, health information systems, access to essential medicines, financing, and leadership/governance) and eight key characteristics of good service delivery models (access, coverage, quality, safety, improved health, responsiveness, social and financial risk protection, and improved efficiency). Findings were synthesized qualitatively to identify components, impacts, barriers, and facilitators of care models.

RESULTS

A care model represents various collective interventions in the healthcare delivery aimed at achieving desired outcomes. The names of these care models are derived from core activities or major responsibilities, involved healthcare teams, diseases conditions, eligible clients, purposes, and care settings. Notable care models include the Integrated, Collaborative, Integrated-Collaborative, Guided, Nurse-led, Geriatric, and Chronic care models, as well as All-inclusive Care Model for the Elderly, IMPACT clinic, and Geriatric Patient-Aligned Care Teams (GeriPACT). Other care models (include Care Management Plus, Value Stream Mapping, Preventive Home Visits, Transition Care, Self-Management, and Care Coordination) have supplemented the main ones. Care models improved quality of care (such as access, patient-centeredness, timeliness, safety, efficiency), cost of care, and quality of life for patients that were facilitated by presence of shared mission, system and function integration, availability of resources, and supportive tools.

CONCLUSIONS

Care models were implemented for the purpose of enhancing quality of care, health outcomes, cost efficiency, and patient satisfaction by considering careful recruitment of eligible clients, appropriate selection of service delivery settings, and robust organizational arrangements involving leadership roles, healthcare teams, financial support, and health information systems. The distinct team compositions and their roles in service provision processes differentiate care models.

Models for delivery and co-ordination of primary or secondary health care (or both) to older adults living in aged care facilities

BACKGROUND

The number of older people is increasing worldwide and public expenditure on residential aged care facilities (ACFs) is expected to at least double, and possibly triple, by 2050. Co-ordinated and timely care in residential ACFs that reduces unnecessary hospital transfers may improve residents' health outcomes and increase satisfaction with care among ACF residents, their families and staff. These benefits may outweigh the resources needed to sustain the changes in care delivery and potentially lead to cost savings. Our systematic review comprehensively and systematically presents the available evidence of the effectiveness, safety and cost-effectiveness of alternative models of providing health care to ACF residents.

OBJECTIVES

Main objective To assess the effectiveness and safety of alternative models of delivering primary or secondary health care (or both) to older adults living in ACFs. Secondary objective To assess the cost-effectiveness of the alternative models.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, five other databases and two trials registers (WHO ICTRP, ClinicalTrials.gov) on 26 October 2022, together with reference checking, citation searching and contact with study authors to identify additional studies.

SELECTION CRITERIA

We included individual and cluster-randomised trials, and cost/cost-effectiveness data collected alongside eligible effectiveness studies. Eligible study participants included older people who reside in an ACF as their place of permanent abode and healthcare professionals delivering or co-ordinating the delivery of healthcare at ACFs. Eligible interventions focused on either ways of delivering primary or secondary health care (or both) or ways of co-ordinating the delivery of this care. Eligible comparators included usual care or another model of care. Primary outcomes were emergency department visits, unplanned hospital admissions and adverse effects (defined as infections, falls and pressure ulcers). Secondary outcomes included adherence to clinical guideline-recommended care, health-related quality of life of residents, mortality, resource use, access to primary or specialist healthcare services, any hospital admissions, length of hospital stay, satisfaction with the health care by residents and their families, work-related satisfaction and work-related stress of ACF staff.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, extracted data, and assessed risk of bias and certainty of evidence using GRADE. The primary comparison was any alternative model of care versus usual care.

MAIN RESULTS

We included 40 randomised trials (21,787 participants; three studies only reported number of beds) in this review. Included trials evaluated alternative models of care aimed at either all residents of the ACF (i.e. no specific health condition; 11 studies), ACF residents with mental health conditions or behavioural problems (12 studies), ACF residents with a specific condition (e.g. residents with pressure ulcers, 13 studies) or residents requiring a specific type of care (e.g. residents after hospital discharge, four studies). Most alternative models of care focused on 'co-ordination of care' (n = 31). Three alternative models of care focused on 'who provides care' and two focused on 'where care is provided' (i.e. care provided within ACF versus outside of ACF). Four models focused on the use of information and communication technology. Usual care, the comparator in all studies, was highly heterogeneous across studies and, in most cases, was poorly reported. Most of the included trials were susceptible to some form of bias; in particular, performance (89%), reporting (66%) and detection (42%) bias. Compared to usual care, alternative models of care may make little or no difference to the proportion of residents with at least one emergency department visit (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.84 to 1.20; 7 trials, 1276 participants; low-certainty evidence), but may reduce the proportion of residents with at least one unplanned hospital admission (RR 0.74, 95% CI 0.56 to 0.99, I2 = 53%; 8 trials, 1263 participants; low-certainty evidence). We are uncertain of the effect of alternative models of care on adverse events (proportion of residents with a fall: RR 1.15, 95% CI 0.83 to 1.60, I² = 74%; 3 trials, 1061 participants; very low-certainty evidence) and adherence to guideline-recommended care (proportion of residents receiving adequate antidepressant medication: RR 5.29, 95% CI 1.08 to 26.00; 1 study, 65 participants) as the certainty of the evidence is very low. Compared to usual care, alternative models of care may have little or no effect on the health-related quality of life of ACF residents (MD -0.016, 95% CI -0.036 to 0.004; I² = 23%; 12 studies, 4016 participants; low-certainty evidence) and probably make little or no difference to the number of deaths in residents of ACFs (RR 1.03, 95% CI 0.92 to 1.16, 24 trials, 3881 participants, moderate-certainty evidence). We did not pool the cost-effectiveness or cost data as the specific costs associated with the various alternative models of care were incomparable, both across models of care as well as across settings. Based on the findings of five economic evaluations (all interventions focused on co-ordination of care), we are uncertain of the cost-effectiveness of alternative models of care compared to usual care as the certainty of the evidence is very low.

AUTHORS' CONCLUSIONS

Compared to usual care, alternative models of care may make little or no difference to the number of emergency department visits but may reduce unplanned hospital admissions. We are uncertain of the effect of alternative care models on adverse events (i.e. falls, pressure ulcers, infections) and adherence to guidelines compared to usual care, as the certainty of the evidence is very low. Alternative models of care may have little or no effect on health-related quality of life and probably have no effect on mortality of ACF residents compared to usual care. Importantly, we are uncertain of the cost-effectiveness of alternative models of care due to the limited, disparate data available.

Health, social care and technological interventions to improve functional ability of older adults living at home: An evidence and gap map

Background

By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value.

Objectives

This evidence and gap map aims to identify primary studies and systematic reviews of health and social support services as well as assistive devices designed to support functional ability among older adults living at home or in other places of residence.

Search Methods

We systematically searched from inception to August 2018 in: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, PsycINFO, AgeLine, Campbell Library, ASSIA, Social Science Citation Index and Social Policy & Practice. We conducted a focused search for grey literature and protocols of studies (e.g., ProQuest Theses and Dissertation Global, conference abstract databases, Help Age, PROSPERO, Cochrane and Campbell libraries and ClinicalTrials.gov).

Selection Criteria

Screening and data extraction were performed independently in duplicate according to our intervention and outcome framework. We included completed and on-going systematic reviews and randomized controlled trials of effectiveness on health and social support services provided at home, assistive products and technology for personal indoor and outdoor mobility and transportation as well as design, construction and building products and technology of buildings for private use such as wheelchairs, and ramps.

Data Collection and Analysis

We coded interventions and outcomes, and the number of studies that assessed health inequities across equity factors. We mapped outcomes based on the International Classification of Function, Disability and Health (ICF) adapted categories: intrinsic capacities (body function and structures) and functional abilities (activities). We assessed methodological quality of systematic reviews using the AMSTAR II checklist.

Main Results

After de-duplication, 10,783 records were screened. The map includes 548 studies (120 systematic reviews and 428 randomized controlled trials). Interventions and outcomes were classified using domains from the International Classification of Function, Disability and Health (ICF) framework. Most systematic reviews (n = 71, 59%) were rated low or critically low for methodological quality.The most common interventions were home-based rehabilitation for older adults (n = 276) and home-based health services for disease prevention (n = 233), mostly delivered by visiting healthcare professionals (n = 474). There was a relative paucity of studies on personal mobility, building adaptations, family support, personal support and befriending or friendly visits. The most measured intrinsic capacity domains were mental function (n = 269) and neuromusculoskeletal function (n = 164). The most measured outcomes for functional ability were basic needs (n = 277) and mobility (n = 160). There were few studies which evaluated outcome domains of social participation, financial security, ability to maintain relationships and communication.There was a lack of studies in low- and middle-income countries (LMICs) and a gap in the assessment of health equity issues.

Authors' Conclusions

There is substantial evidence for interventions to promote functional ability in older adults at home including mostly home-based rehabilitation for older adults and home-based health services for disease prevention. Remotely delivered home-based services are of greater importance to policy-makers and practitioners in the context of the COVID-19 pandemic. This map of studies published prior to the pandemic provides an initial resource to identify relevant home-based services which may be of interest for policy-makers and practitioners, such as home-based rehabilitation and social support, although these interventions would likely require further adaptation for online delivery during the COVID-19 pandemic. There is a need to strengthen assessment of social support and mobility interventions and outcomes related to making decisions, building relationships, financial security, and communication in future studies. More studies are needed to assess LMIC contexts and health equity issues.

Home-Based Primary and Palliative Care in the Medicaid Program: Systematic Review of the Literature

BACKGROUND/OBJECTIVES

To describe the use of home-based medical care (HBMC) among Medicaid beneficiaries.

DESIGN

A systematic review of the peer-reviewed and gray literature of home-based primary care and palliative care programs among Medicaid beneficiaries including dual eligibles.

SETTING

HBMC including home-based primary care and palliative care programs.

PARTICIPANTS

Studies describing Medicaid beneficiaries receiving HBMC.

MEASUREMENTS

Three groups of studies were included: those focused on HBMC specifically for Medicaid beneficiaries, studies that described the proportion of Medicaid patients receiving HBMC, and those that used Medicaid status as a dependent variable in studying HBMC.

RESULTS

The peer-reviewed and gray literature searches revealed 574 unique studies of which only 16 met inclusion criteria. Few publications described HBMC as an integral care delivery model for Medicaid programs. Data from the programs described suggest the use of HBMC for Medicaid beneficiaries can reduce healthcare costs. The addition of social supports to HBMC appears to convey additional savings and benefits.

CONCLUSION

This systematic literature review highlights the relative dearth of literature regarding the use and impact of HBMC in the Medicaid population. HBMC has great potential to reduce Medicaid costs, and innovative programs combining HBMC with social support systems need to be tested.

Goal-Oriented Care: A Catalyst for Person-Centred System Integration

Introduction

Person-centred integrated care is often at odds with how current health care systems are structured, resulting in slower than expected uptake of the model worldwide. Adopting goal-oriented care, an approach which uses patient priorities, or goals, to drive what kinds of care are appropriate and how care is delivered, may offer a way to improve implementation.

Description

This case report presents three international cases of community-based primary health care models in Ottawa (Canada), Vermont (USA) and Flanders (Belgium) that adopted goal-oriented care to stimulate clinical, professional, organizational and system integration. The Rainbow Model of Integrated Care is used to demonstrate how goal-oriented care drove integration at all levels.

Discussion

The three cases demonstrate how goal-oriented care has the potential to catalyse integrated care. Exploration of these cases suggests that goal-oriented care can serve to activate formative and normative integration mechanisms; supporting processes that enable integrated care, while providing a framework for a shared philosophy of care.

Lessons learned

By establishing a common vision and philosophy to drive shared processes, goal-oriented care can be a powerful tool to enable integrated care delivery. Offering plenty of opportunities for training in goal-oriented care within and across teams is essential to support this shift.

How the Integration of Telehealth and Coordinated Care Approaches Impact Health Care Service Organization Structure and Ethos: Mixed Methods Study

Background

Coordinated care and telehealth services have the potential to deliver quality care to chronically ill patients. They can both reduce the economic burden of chronic care and maximize the delivery of clinical services. Such services require new behaviors, routines, and ways of working to improve health outcomes, administrative efficiency, cost-effectiveness, and user (patient and health professional) experience.

Objective

The aim of this study was to assess how health care organization setup influences the perceptions and experience of service managers and frontline staff during the development and deployment of integrated care with and without telehealth.

Methods

As part of a multinational project exploring the use of coordinated care and telehealth, questionnaires were sent to service managers and frontline practitioners. These questionnaires gathered quantitative and qualitative data related to organizational issues in the implementation of coordinated care and telehealth. Three analytical stages were followed: (1) preliminary analysis for a direct comparison of the responses of service managers and frontline staff to a range of organizational issues, (2) secondary analysis to establish statistically significant relationships between baseline and follow-up questionnaires, and (3) thematic analysis of free-text responses of service managers and frontline staff.

Results

Both frontline practitioners and managers highlighted that training, tailored to the needs of different professional groups and staff grades, was a crucial element in the successful implementation of new services. Frontline staff were markedly less positive than managers in their views regarding the responsiveness of their organization and the pace of change.

Conclusions

The data provide evidence that the setup of health care services is positively associated with outcomes in several areas, particularly tailored staff training, rewards for good service, staff satisfaction, and patient involvement.

Nurses' competencies in health promotion for homebound older people

OBJECTIVE

to identify competencies related to health promotion targeting homebound older people, as they appear in the literature.

METHOD

systematic review using the LILACS, Scopus, CINAHL, PubMed and Cochrane Library databases. The search was performed in November 2017. Selected articles were analyzed according to nine competency domains: enable change; advocate for health; mediate through partnership; communication; leadership; assessment; planning; implementation, and evaluation and research.

RESULTS

nine clinical trials were included. All health promotion competency domains were identified in the reviewed research interventions, performed with homebound older people.

CONCLUSION

studies showed that the employed treatments were beneficial for the homebound older population. Interventions based on health promotion competencies were positively identified, and are linked to an effective and high-quality health care practice.

An Innovation Center Model to Transform Health Systems to Improve Care of Older Adults

The US population is aging faster than at any other time in our history. This growth, coupled with a slow adaptive health policy framework, is creating an urgent need to reengineer and improve the quality, safety, and cost-effectiveness of health systems to meet the needs of older adults and embrace the success we have achieved with longevity. Without rapid adoption of evidence-based models that are known to improve safety and health outcomes, we significantly jeopardize the lives of thousands of older adults receiving care under our current health systems' processes and models. This article describes an innovation and operations infrastructure that was successfully tested in two independent and geographically distinct community health systems. This operations and implementation framework can be scaled and used to accelerate the changes needed to improve care for older adults in health systems throughout the United States.

Implementing advance care planning with community-dwelling frail elders requires a system-wide approach: An integrative review applying a behaviour change model

BACKGROUND

Facilitating advance care planning with community-dwelling frail elders can be challenging. Notably, frail elders' vulnerability to sudden deterioration leads to uncertainty in recognising the timing and focus of advance care planning conversations.

AIM

To understand how advance care planning can be better implemented for community-dwelling frail elders and to develop a conceptual model to underpin intervention development.

DESIGN

A structured integrative review of relevant literature.

DATA SOURCES

CINAHL, Embase, Ovid Medline, PsycINFO, Cochrane Library, and University of York Centre for Reviews and Dissemination. Further strategies included searching for policy and clinical documents, grey literature, and hand-searching reference lists. Literature was searched from 1990 until October 2018.

RESULTS

From 3043 potential papers, 42 were included. Twenty-nine were empirical, six expert commentaries, four service improvements, two guidelines and one theoretical. Analysis revealed nine themes: education and training, personal ability, models, recognising triggers, resources, conversations on death and dying, living day to day, personal beliefs and experience, and relationality.

CONCLUSION

Implementing advance care planning for frail elders requires a system-wide approach, including providing relevant resources and clarifying responsibilities. Early engagement is key for frail elders, as is a shift from the current advance care planning model focussed on future ceilings of care to one that promotes living well now alongside planning for the future. The proposed conceptual model can be used as a starting point for professionals, organisations and policymakers looking to improve advance care planning for frail elders.

Interventions to improve the appropriate use of polypharmacy for older people

BACKGROUND

Inappropriate polypharmacy is a particular concern in older people and is associated with negative health outcomes. Choosing the best interventions to improve appropriate polypharmacy is a priority, hence interest in appropriate polypharmacy, where many medicines may be used to achieve better clinical outcomes for patients, is growing. This is the second update of this Cochrane Review.

OBJECTIVES

To determine which interventions, alone or in combination, are effective in improving the appropriate use of polypharmacy and reducing medication-related problems in older people.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers up until 7 February 2018, together with handsearching of reference lists to identify additional studies.

SELECTION CRITERIA

We included randomised trials, non-randomised trials, controlled before-after studies, and interrupted time series. Eligible studies described interventions affecting prescribing aimed at improving appropriate polypharmacy in people aged 65 years and older, prescribed polypharmacy (four or more medicines), which used a validated tool to assess prescribing appropriateness. These tools can be classified as either implicit tools (judgement-based/based on expert professional judgement) or explicit tools (criterion-based, comprising lists of drugs to be avoided in older people).

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed abstracts of eligible studies, extracted data and assessed risk of bias of included studies. We pooled study-specific estimates, and used a random-effects model to yield summary estimates of effect and 95% confidence intervals (CIs). We assessed the overall certainty of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We identified 32 studies, 20 from this update. Included studies consisted of 18 randomised trials, 10 cluster randomised trials (one of which was a stepped-wedge design), two non-randomised trials and two controlled before-after studies. One intervention consisted of computerised decision support (CDS); and 31 were complex, multi-faceted pharmaceutical-care based approaches (i.e. the responsible provision of medicines to improve patient's outcomes), one of which incorporated a CDS component as part of their multi-faceted intervention. Interventions were provided in a variety of settings. Interventions were delivered by healthcare professionals such as general physicians, pharmacists and geriatricians, and all were conducted in high-income countries. Assessments using the Cochrane 'Risk of bias' tool, found that there was a high and/or unclear risk of bias across a number of domains. Based on the GRADE approach, the overall certainty of evidence for each pooled outcome ranged from low to very low.It is uncertain whether pharmaceutical care improves medication appropriateness (as measured by an implicit tool), mean difference (MD) -4.76, 95% CI -9.20 to -0.33; 5 studies, N = 517; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the number of potentially inappropriate medications (PIMs), (standardised mean difference (SMD) -0.22, 95% CI -0.38 to -0.05; 7 studies; N = 1832; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PIMs, (risk ratio (RR) 0.79, 95% CI 0.61 to 1.02; 11 studies; N = 3079; very low-certainty evidence). Pharmaceutical care may slightly reduce the number of potential prescribing omissions (PPOs) (SMD -0.81, 95% CI -0.98 to -0.64; 2 studies; N = 569; low-certainty evidence), however it must be noted that this effect estimate is based on only two studies, which had serious limitations in terms of risk bias. Likewise, it is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PPOs (RR 0.40, 95% CI 0.18 to 0.85; 5 studies; N = 1310; very low-certainty evidence). Pharmaceutical care may make little or no difference in hospital admissions (data not pooled; 12 studies; N = 4052; low-certainty evidence). Pharmaceutical care may make little or no difference in quality of life (data not pooled; 12 studies; N = 3211; low-certainty evidence). Medication-related problems were reported in eight studies (N = 10,087) using different terms (e.g. adverse drug reactions, drug-drug interactions). No consistent intervention effect on medication-related problems was noted across studies.

AUTHORS' CONCLUSIONS

It is unclear whether interventions to improve appropriate polypharmacy, such as reviews of patients' prescriptions, resulted in clinically significant improvement; however, they may be slightly beneficial in terms of reducing potential prescribing omissions (PPOs); but this effect estimate is based on only two studies, which had serious limitations in terms of risk bias.

Relevant models and elements of integrated care for multi-morbidity: Results of a scoping review

BACKGROUND

In order to provide adequate care for the growing group of persons with multi-morbidity, innovative integrated care programmes are appearing. The aims of the current scoping review were to i) identify relevant models and elements of integrated care for multi-morbidity and ii) to subsequently identify which of these models and elements are applied in integrated care programmes for multi-morbidity.

METHODS

A scoping review was conducted in the following scientific databases: Cochrane, Embase, PubMed, PsycInfo, Scopus, Sociological Abstracts, Social Services Abstracts, and Web of Science. A search strategy encompassing a) models, elements and programmes, b) integrated care, and c) multi-morbidity was used to identify both models and elements (aim 1) and implemented programmes of integrated care for multi-morbidity (aim 2). Data extraction was done by two independent reviewers. Besides general information on publications (e.g. publication year, geographical region, study design, and target group), data was extracted on models and elements that publications refer to, as well as which models and elements are applied in recently implemented programmes in the EU and US.

RESULTS

In the review 11,641 articles were identified. After title and abstract screening, 272 articles remained. Full text screening resulted in the inclusion of 92 articles on models and elements, and 50 articles on programmes, of which 16 were unique programmes in the EU (n=11) and US (n=5). Wagner's Chronic Care Model (CCM) and the Guided Care Model (GCM) were most often referred to (CCM n=31; GCM n=6); the majority of the other models found were only referred to once (aim 1). Both the CCM and GCM focus on integrated care in general and do not explicitly focus on multi-morbidity. Identified elements of integrated care were clustered according to the WHO health system building blocks. Most elements pertained to 'service delivery'. Across all components, the five elements referred to most often are person-centred care, holistic or needs assessment, integration and coordination of care services and/or professionals, collaboration, and self-management (aim 1). Most (n=10) of the 16 identified implemented programmes for multi-morbidity referred to the CCM (aim 2). Of all identified programmes, the elements most often included were self-management, comprehensive assessment, interdisciplinary care or collaboration, person-centred care and electronic information system (aim 2).

CONCLUSION

Most models and elements found in the literature focus on integrated care in general and do not explicitly focus on multi-morbidity. In line with this, most programmes identified in the literature build on the CCM. A comprehensive framework that better accounts for the complexities resulting from multi-morbidity is needed.

Expanding palliative care's reach in the community via the elder service agency network

Over the past two decades, palliative care has established itself as a promising approach to address the complex needs of individuals with advanced illness. Palliative care is well-established in US hospitals and has recently begun to expand outside of the hospital setting to meet the needs of non-hospitalized individuals. Experts have called for the development of innovative community-based models that facilitate delivery of palliative care to this target population. Elder service agencies are important partners that researchers should collaborate with to develop new and promising models. Millions of older adults receive aging network services in the U.S., highlighting the potential reach of these models. Recent health care reform efforts provide support for community-based initiatives, where coordination of care and services, delivered via health and social service agencies, is highly prioritized. This article describes the rationale for developing such approaches, including efforts to educate elder service agency clients about palliative care; training agency staff in palliative care principles; building capacity for elder services providers to screen individuals for palliative care needs; embedding palliative care "champions" in agencies to educate staff and clients and coordinate access to services among those with palliative care needs; and leveraging telehealth resources to conduct comprehensive assessments by hospital palliative care teams for elder service clients who have palliative care needs. We maintain that leveraging the resources of elder service agencies could measurably expand the reach of palliative care in the community.

Care models for people with chronic diseases: integrative review

OBJECTIVES

To identify the care models and the impact of the use of these in the care of people with chronic diseases reported in the literature in the years 2000 to 2014.

METHODS

Integrative literature review in which the following guiding question was adopted: Which care models are used in the care of patients with chronic diseases and what impacts can be verified through their application? We consulted the bibliographic databases Virtual Health Library, LILACS, MEDLINE, Spanish Bibliographic Index of Health Sciences and the Database of Nursing.

RESULTS

The sample consisted of 17 articles on the topic of interest. Three categories emerged from the analysis: health care costs, model-based care experience, and patient autonomy. The articles addressed self-management, case management and care model for people with chronic diseases. The major impacts on the use of the models were: a better relationship between the patient and the health professional, an increase in the autonomy of the person with chronic illness, and a reduction in personal and health care expenditure.

CONCLUSIONS

The use of care models for people with chronic diseases presents benefits to the patient and to the health system. Nurses must actively participate in the application of these care models of people with this type of illness.

Measured outcomes of chronic care programs for older adults: a systematic review

Background

Wagner’s Chronic Care Model (CCM), as well as the expanded version (ECCM) developed by Barr and colleagues, have been widely adopted as frameworks for prevention and management of chronic disease. Given the high prevalence of chronic illness in older persons, these frameworks can play a valuable role in reorienting the health care system to better serve the needs of seniors. We aimed to identify and assess the measured goals of E/CCM interventions in older populations. In particular, our objective was to determine the extent to which published E/CCM initiatives were evaluated based on population, community, system and individual-level outcomes (including clinical, functional and quality of life measures).

Methods

We conducted a systematic search of the Science Citation Index Web of Knowledge search tool to gather articles published between January 2003 and July 2014. We included published CCM interventions that cited at least one of the fundamental papers that introduced and described the CCM and ECCM. Studies retained for review reported evaluations of senior-focused E/CCM initiatives in community-based settings, with the topic of “older adults” OR senior* OR elder* OR geriatric OR aged. The resulting 619 published articles were independently reviewed for inclusion by two researchers. We excluded the following: systematic reviews, meta-analyses, descriptions of proposed programs, and studies whose populations did not focus on seniors.

Results

We identified 14 articles that met inclusion criteria. Studies used a wide range of measures, with little consensus between studies. All of the included studies used the original CCM. While a range of system-level and individual patient outcomes have been used to evaluate CCM interventions, no studies employed measures of population or community health outcomes.

Conclusions

Future efforts to test E/CCM interventions with seniors would be aided by more consistent outcome measures, greater attention to outcomes for the caregivers of older persons with chronic illness, and a greater focus on population and community impacts.

Beneficiary activation in the Medicare population

OBJECTIVE

Patient activation questions from a major national Medicare survey are used to highlight characteristics of Medicare beneficiaries with low activation. We demonstrate that Medicare Current Beneficiary Survey (MCBS) data is an untapped resource for further research on patient activation within Medicare beneficiaries and programs.

DATA SOURCE

Data are from the 2012 MCBS Access to Care file and include 10,650 beneficiaries.

METHODS

Patient Activation levels were derived by taking the weighted average responses to the Patient Activation Supplement. Cut points for high, moderate, and low activation were assigned at +/- ½ standard deviation of the mean. Data were analyzed using SAS survey procedures. Within group comparisons were tested using chi-square tests with post hoc pairwise comparisons. Logistic regression identified predictors of low patient engagement.

RESULTS

In a multiple logistic regression, beneficiary characteristics associated with low activation included Hispanic origin, being widowed or never married, select age groups, male gender, fair or poor health, difficulty with an IADL or ADLs, and having no usual source of care, with failure to complete high school as the strongest predictor (OR=2.22, p<.001). Utilization and costs were also examined in descriptive analyses.

DISCUSSION

Overall, findings on the characteristics of low activation patients in the Medicare population resemble previous research. In a regression analysis, less education and no usual source of care are the strongest predictors of low activation levels in Medicare beneficiaries. The MCBS Patient Activation Supplement is a rich resource for examining patient activation in the Medicare population, and can be used for a wide range of analyses.

Interventions to improve the appropriate use of polypharmacy for older people

BACKGROUND

Inappropriate polypharmacy is a particular concern in older people and is associated with negative health outcomes. Choosing the best interventions to improve appropriate polypharmacy is a priority, hence interest in appropriate polypharmacy, where many medicines may be used to achieve better clinical outcomes for patients, is growing.

OBJECTIVES

This review sought to determine which interventions, alone or in combination, are effective in improving the appropriate use of polypharmacy and reducing medication-related problems in older people.

SEARCH METHODS

In November 2013, for this first update, a range of literature databases including MEDLINE and EMBASE were searched, and handsearching of reference lists was performed. Search terms included 'polypharmacy', 'medication appropriateness' and 'inappropriate prescribing'.

SELECTION CRITERIA

A range of study designs were eligible. Eligible studies described interventions affecting prescribing aimed at improving appropriate polypharmacy in people 65 years of age and older in which a validated measure of appropriateness was used (e.g. Beers criteria, Medication Appropriateness Index (MAI)).

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed abstracts of eligible studies, extracted data and assessed risk of bias of included studies. Study-specific estimates were pooled, and a random-effects model was used to yield summary estimates of effect and 95% confidence intervals (CIs). The GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach was used to assess the overall quality of evidence for each pooled outcome.

MAIN RESULTS

Two studies were added to this review to bring the total number of included studies to 12. One intervention consisted of computerised decision support; 11 complex, multi-faceted pharmaceutical approaches to interventions were provided in a variety of settings. Interventions were delivered by healthcare professionals, such as prescribers and pharmacists. Appropriateness of prescribing was measured using validated tools, including the MAI score post intervention (eight studies), Beers criteria (four studies), STOPP criteria (two studies) and START criteria (one study). Interventions included in this review resulted in a reduction in inappropriate medication usage. Based on the GRADE approach, the overall quality of evidence for all pooled outcomes ranged from very low to low. A greater reduction in MAI scores between baseline and follow-up was seen in the intervention group when compared with the control group (four studies; mean difference -6.78, 95% CI -12.34 to -1.22). Postintervention pooled data showed a lower summated MAI score (five studies; mean difference -3.88, 95% CI -5.40 to -2.35) and fewer Beers drugs per participant (two studies; mean difference -0.1, 95% CI -0.28 to 0.09) in the intervention group compared with the control group. Evidence of the effects of interventions on hospital admissions (five studies) and of medication-related problems (six studies) was conflicting.

AUTHORS' CONCLUSIONS

It is unclear whether interventions to improve appropriate polypharmacy, such as pharmaceutical care, resulted in clinically significant improvement; however, they appear beneficial in terms of reducing inappropriate prescribing.

Contrasting effects of geriatric versus general medical multimorbidity on quality of ambulatory care

OBJECTIVES

To determine whether greater burden of geriatric conditions would have contrasting effects on quality of care (QOC) than nongeriatric, general medical conditions.

DESIGN

Cross-sectional observation over 1 year of ambulatory care.

SETTING

The Assessing Care of Vulnerable Elders-2 study.

PARTICIPANTS

Older adults prospectively screened for falls, incontinence, and dementia (N = 644).

MEASUREMENTS

Participant-level QOC in absolute percentage points calculated using 65 ambulatory care care-process quality indicators (QIs) for 13 general medical and geriatric conditions (#QIs provided/#QIs eligible). Secondary outcomes were geriatric QOC (a subset of 38 geriatric care QIs) and medical QOC (the 27 remaining nongeriatric QIs). Exposure variables were number of six medical conditions (medical comorbidity) and six geriatric conditions (geriatric comorbidity), controlling for age, sex, number of primary care visits, and site.

RESULTS

Medical and geriatric comorbidity were unrelated to each other (correlation coefficient = 0.04, P = .27) yet had opposite effects on QOC. Each additional medical condition was associated with a 3.2-percentage point (95% confidence interval (CI) = 2.3-4.2 percentage point) increment in QOC, and each additional geriatric condition was associated with 4.9-percentage point (95% CI = 3.5-6.5 percentage point) decrement in QOC. Participants with greater geriatric comorbidity received poorer medical and geriatric QOC.

CONCLUSION

Greater burden of geriatric conditions, or geriatric multimorbidity, is associated with poorer QOC. Geriatric multimorbidity should be targeted for better care using a comprehensive approach.

The Relationship Between Organizational Characteristics and Advance Care Planning Practices

Organizational characteristics may impede the uniform adoption of advance care planning (ACP) best practices. We conducted telephone interviews with site directors of a Midwestern state’s Medicaid waiver program administered by the Area Agencies on Aging and surveyed the 433 care managers (registered nurses and social workers) employed within these 9 agencies. Care managers at 2 agencies reported more frequent ACP discussions and higher levels of confidence. Both sites had ACP training programs, follow-up protocols, and informational packets available for consumers that were not consistently available at the other agencies. The findings point to the need for consistent educational programs and policies on ACP and more in depth examination of the values, beliefs, and resources that account for organizational differences in ACP.

Effectiveness and cost-effectiveness of home palliative care services for adults with advanced illness and their caregivers

BACKGROUND

Extensive evidence shows that well over 50% of people prefer to be cared for and to die at home provided circumstances allow choice. Despite best efforts and policies, one-third or less of all deaths take place at home in many countries of the world.

OBJECTIVES

1. To quantify the effect of home palliative care services for adult patients with advanced illness and their family caregivers on patients' odds of dying at home; 2. to examine the clinical effectiveness of home palliative care services on other outcomes for patients and their caregivers such as symptom control, quality of life, caregiver distress and satisfaction with care; 3. to compare the resource use and costs associated with these services; 4. to critically appraise and summarise the current evidence on cost-effectiveness.

SEARCH METHODS

We searched 12 electronic databases up to November 2012. We checked the reference lists of all included studies, 49 relevant systematic reviews, four key textbooks and recent conference abstracts. We contacted 17 experts and researchers for unpublished data.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series (ITSs) evaluating the impact of home palliative care services on outcomes for adults with advanced illness or their family caregivers, or both.

DATA COLLECTION AND ANALYSIS

One review author assessed the identified titles and abstracts. Two independent reviewers performed assessment of all potentially relevant studies, data extraction and assessment of methodological quality. We carried out meta-analysis where appropriate and calculated numbers needed to treat to benefit (NNTBs) for the primary outcome (death at home).

MAIN RESULTS

We identified 23 studies (16 RCTs, 6 of high quality), including 37,561 participants and 4042 family caregivers, largely with advanced cancer but also congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), HIV/AIDS and multiple sclerosis (MS), among other conditions. Meta-analysis showed increased odds of dying at home (odds ratio (OR) 2.21, 95% CI 1.31 to 3.71; Z = 2.98, P value = 0.003; Chi(2) = 20.57, degrees of freedom (df) = 6, P value = 0.002; I(2) = 71%; NNTB 5, 95% CI 3 to 14 (seven trials with 1222 participants, three of high quality)). In addition, narrative synthesis showed evidence of small but statistically significant beneficial effects of home palliative care services compared to usual care on reducing symptom burden for patients (three trials, two of high quality, and one CBA with 2107 participants) and of no effect on caregiver grief (three RCTs, two of high quality, and one CBA with 2113 caregivers). Evidence on cost-effectiveness (six studies) is inconclusive.

AUTHORS' CONCLUSIONS

The results provide clear and reliable evidence that home palliative care increases the chance of dying at home and reduces symptom burden in particular for patients with cancer, without impacting on caregiver grief. This justifies providing home palliative care for patients who wish to die at home. More work is needed to study cost-effectiveness especially for people with non-malignant conditions, assessing place of death and appropriate outcomes that are sensitive to change and valid in these populations, and to compare different models of home palliative care, in powered studies.

Narrative analysis of the ethics in providing advance care planning

Our objective was to better understand the values and ethical dilemmas surrounding advance care planning through stories told by registered nurses and licensed social workers, who were employed as care managers within Area Agencies on Aging. We conducted eight focus groups in which care managers were invited to tell their stories and answer open-ended questions focusing on their interactions with consumers receiving home-based long-term care. Using narrative analysis to understand how our participants thought through particular experiences and what they valued, we identified seven themes representative of their work with consumers and families: humility, respect, responsibilities, boundaries, empowerment, courage, and veracity.

Factors Associated With Advance Care Planning Discussions by Area Agency on Aging Care Managers

Background:

Initiating advance care planning (ACP) discussions in the home may prevent avoidable hospitalizations by elucidating goals of care. Area agencies on aging care managers (AAACMs) work in the home with high-risk consumers.

Purpose:

To determine which AAACM characteristics contribute to an increased frequency of ACP discussions.

Method:

Cross-sectional investigator-generated surveys administered to AAACMs at 3 AAAs in Ohio. Results: Of 289 AAACMs, 182 (63%) responded. The more experience and comfort AAACMs felt with ACP discussions, the more likely they were to initiate ACP discussions.

Discussion:

It may be necessary to build interactive educational experiences where, for example, AAACMs are asked to fill out their own advance directives and/or facilitate others in ACP discussions to improve experience and comfort with ACP discussions.

Managing in the trenches of consumer care: the challenges of understanding and initiating the advance care planning process

To better understand how community-based long-term care providers define advance care planning and their role in the process, we conducted 8 focus groups with 62 care managers (social workers and registered nurses) providing care for Ohio's Medicaid waiver program. Care managers shared that most consumers had little understanding of advance care planning. The care managers defined it broadly, including legal documentation, social aspects, medical considerations, ongoing communication, and consumer education. Care managers saw their roles as information providers, healthcare team members, and educators/coaches. Better education, resources, and coordination are needed to ensure that consumer preferences are realized.
