Recognizing 30 Years of Accomplishments and Envisioning an Innovative Future - The 2024 Annual Conference of the Health Care Systems Research Network

The Health Care Systems Research Network (HCSRN) kicked off the 2024 Annual Conference on April 9, 2024, in Milwaukee at the Hyatt Regency with nearly 275 participants from 19 HCSRN member institutions. This year, HCSRN attendees joined their colleagues to reconnect and network during the three-day conference featuring the theme, "Advancing High-Quality, Equitable Research in the Age of New Health Care Technologies."

Prevalence and Appropriateness of Polypharmacy in Older Adults with Inflammatory Bowel Diseases

BACKGROUND

Despite the growing prevalence of older adults with inflammatory bowel diseases (IBD), polypharmacy, an important geriatric construct, is poorly understood. We described polypharmacy and its implications in older adults with IBD.

METHODS

In a cross sectional study of adults ≥ 60 years with IBD, we obtained medication lists from the medical record and patients. We assessed medications by the Beer's criteria, anti-cholinergic burden and drug-drug interactions. We constructed multi-variate logistic regression models to assess association between polypharmacy with low quality-of-life, controlling for age, sex, IBD-type, number of comorbidities and depression.

RESULTS

In 100 adults ≥ 60 years with IBD, with a median age of 68 years, 56% met criteria for remission by a validated disease activity index. Polypharmacy, defined as ≥ 5 concomitant medications, was noted in 86% of the cohort and 45% had severe polypharmacy, defined as ≥ 10 concomitant medications. In this cohort, 48% were on ≥ 1 medication that met Beer's criteria for potentially inappropriate in older adults and 24% had a cumulative anti-cholinergic drug burden score of ≥ 3, the threshold for serious adverse events attributed to anti-cholinergic burden. Serious drug-drug interactions were found in 26% with 7% involving an IBD medication. Controlling for potential confounders, polypharmacy, defined both numerically (OR 22.79, p < 0.01) and by medication appropriateness (OR 1.95, p < 0.01), was significantly associated with low quality of life.

CONCLUSION

Polypharmacy is prevalent in older adults with IBD and independently associated with low quality of life. Describing polypharmacy can guide de-prescription strategies tailored to GI clinic for older adults with IBD.

What are the priorities for research of older people living in their own home, including those living with frailty? A systematic review and content analysis of studies reporting older people's priorities and unmet needs

BACKGROUND

There is limited evidence regarding the needs of older people, including those living with frailty, to inform research priority setting.

OBJECTIVES

This systematic review aimed to identify the range of research priorities of community-dwelling older people living in their own home, including those living with frailty.

METHODS

Included studies were from economically developed countries and designed to identify the priorities for research or unmet needs of community-dwelling older people. Studies were excluded if they described priorities relating to specific health conditions. Medline, Embase, PsycInfo and CINAHL were searched (January 2010-June 2022), alongside grey literature. Study quality was assessed, but studies were not excluded on the basis of quality. A bespoke data extraction form was used and content analysis undertaken to synthesise findings.

RESULTS

Seventy-five reports were included. Seven explicitly aimed to identify the priorities or unmet needs of frail older people; 68 did not specify frailty as a characteristic. Study designs varied, including priority setting exercises, surveys, interviews, focus groups and literature reviews. Identified priorities and unmet needs were organised into themes: prevention and management, improving health and care service provision, improving daily life, meeting carers' needs and planning ahead.

DISCUSSION

Many priority areas were raised by older people, carers and health/care professionals, but few were identified explicitly by/for frail older people. An overarching need was identified for tailored, collaborative provision of care and support.

CONCLUSION

Review findings provide a valuable resource for researchers and health/care staff wishing to focus their research or service provision on areas of importance for older people.

Multimorbidity trajectories in early adulthood and middle age: Findings from the CARDIA prospective cohort study

Background

Multimorbidity research has focused on the prevalence and consequences of multimorbidity in older populations. Less is known about the accumulation of chronic conditions earlier in the life course.

Methods

We identified patterns of longitudinal multimorbidity accumulation using 30 years of data from in-person exams, annual follow-ups, and adjudicated end-points among 4,945 participants of the Coronary Artery Risk Development in Young Adults (CARDIA) study. Chronic conditions included arthritis, asthma, atrial fibrillation, cancer, end stage renal disease, chronic obstructive pulmonary disease, coronary heart disease, diabetes, heart failure, hyperlipidemia, hypertension, and stroke. Trajectory patterns were identified using latent class growth curve models.

Results

Mean age (SD) at baseline (1985-6) was 24.9 (3.6), 55% were female, and 51% were Black. The median follow-up was 30 years (interquartile range 25-30). We identified six trajectory classes characterized by when conditions began to accumulate and the rapidity of accumulation: (1) early-fifties, slow, (2) mid-forties, fast, (3) mid-thirties, fast, (4) late-twenties, slow, (5) mid-twenties, slow, and (6) mid-twenties, fast. Compared with participants in the early-fifties, slow trajectory class, participants in mid-twenties, fast were more likely to be female, Black, and currently smoking and had a higher baseline mean waist circumference (83.6 vs. 75.6 cm) and BMI (27.0 vs. 23.4 kg/m2) and lower baseline physical activity (414.1 vs. 442.4 exercise units).

Conclusions

A life course approach that recognizes the heterogeneity in patterns of accumulation of chronic conditions from early adulthood into middle age could be helpful for identifying high risk subgroups and developing approaches to delay multimorbidity progression.

Supporting older patients in making healthcare decisions: The effectiveness of decision aids; A systematic review and meta-analysis

OBJECTIVE

To systematically review randomized controlled trials and clinical controlled trials evaluating the effectiveness of Decision Aids (DAs) compared to usual care or alternative interventions for older patients facing treatment, screening, or care decisions.

METHODS

A systematic search of several databases was conducted. Eligible studies included patients ≥ 65 years or reported a mean of ≥ 70 years. Primary outcomes were attributes of the choice made and decision making process, user experience and ways in which DAs were tailored to older patients. Meta-analysis was conducted, if possible, or outcomes were synthesized descriptively.

RESULTS

Overall, 15 studies were included. Using DAs were effective in increasing knowledge (SMD 0.90; 95% CI [0.48, 1.32]), decreasing decisional conflict (SMD -0.15; 95% CI [-0.29, -0.01]), improving patient-provider communication (RR 1.67; 95% CI [1.21, 2.29]), and preparing patients to make an individualized decision (MD 35.7%; 95% CI [26.8, 44.6]). Nine studies provided details on how the DA was tailored to older patients.

CONCLUSION

This review shows a number of favourable results for the effectiveness of DAs in decision making with older patients.

PRACTICE IMPLICATIONS

Current DAs can be used to support shared decision making with older patients when faced with treatment, screening or care decisions.

Exploring the roles and functions of champions within community-based interventions to support older adults with chronic conditions: A scoping review protocol

BACKGROUND

Health care solutions are needed to meet the need of an ageing population. Health care champions are people who endorse the adoption of new initiatives being implemented within health care settings. Although the role of champions has been cited as key to the success of numerous community-based interventions implemented to improve the care of older adults with chronic conditions, no synthesis of their implementation experiences have been conducted. We report on a scoping review protocol that will be applied to collect evidence on the role of champions within community-based health interventions to support older adults with chronic conditions. Specifically, we will identify how the term 'champion' is used and defined (i.e., conceptualized) and identify the roles (i.e., professional background) and functions of champions (i.e., responsibilities). We will also explore how this role impacts program implementation.

METHODS

This is a scoping review protocol informed by guidelines for Scoping Reviews (PRISMA-ScR) and a six-stage scoping review methodology. Peer-review literature will be retrieved from Medline, CINAHL, PubMed, PsycInfo, Cochrane JBI and Scopus databases, using a peer-reviewed search strategy developed in collaboration with an Information Specialist. The scoping review will consider all empirical studies published in English. Two reviewers will pilot-test the screening criteria and data abstraction forms, and then independently screen the literature. Extracted data will be analyzed numerically and thematically. Self-identified champions will be consulted to refine the practice recommendations from this work.

DISCUSSION

This scoping review will broadly and systematically identify, define and expand existing knowledge on champions' impact in implementing community-based interventions to support older adults with chronic conditions. We anticipate that our results will lead to a greater understanding of the characteristics and role champions play within these interventions, which will be relevant to a wide range of knowledge users, including researchers, decision-makers, and health care providers.

Multimorbidity and adverse longitudinal outcomes among patients attending chronic outpatient medical care in Bahir Dar, Northwest Ethiopia

Background

Multimorbidity is becoming more prevalent in low-and middle-income countries (LMICs). However, the evidence base on the burden and its longitudinal outcomes are limited. This study aimed to determine the longitudinal outcomes of patients with multimorbidity among a sample of individuals attending chronic outpatient non communicable diseases (NCDs) care in Bahir Dar, northwest Ethiopia.

Methods

A facility-based longitudinal study was conducted among 1,123 participants aged 40+ attending care for single NCD (n = 491) or multimorbidity (n = 633). Data were collected both at baseline and after 1 year through standardized interviews and record reviews. Data were analyzed using Stata V.16. Descriptive statistics and longitudinal panel data analyzes were run to describe independent variables and identify factors predicting outcomes. Statistical significance was considered at p-value <0.05.

Results

The magnitude of multimorbidity has increased from 54.8% at baseline to 56.8% at 1 year. Four percent (n = 44) of patients were diagnosed with one or more NCDs and those having multimorbidity at baseline were more likely than those without multimorbidity to develop new NCDs. In addition, 106 (9.4%) and 22 (2%) individuals, respectively were hospitalized and died during the follow up period. In this study, about one-third of the participants had higher quality of life (QoL), and those having higher high activation status were more likely to be in the higher versus the combined moderate and lower QoL [AOR1 = 2.35, 95%CI: (1.93, 2.87)] and in the combined higher and moderate versus lower level of QoL [AOR2 = 1.53, 95%CI: (1.25, 1.88)].

Conclusion

Developing new NCDs is a frequent occurrence and the prevalence of multimorbidity is high. Living with multimorbidity was associated with poor progress, hospitalization and mortality. Patients having a higher activation level were more likely than those with low activation to have better QoL. If health systems are to meet the needs of the people with chronic conditions and multimorbidity, it is essential to understand diseases trajectories and of impact of multimorbidity on QoL, and determinants and individual capacities, and to increase their activation levels for better health improve outcomes through education and activation.

Individualized interventions and precision health: Lessons learned from a systematic review and implications for analytics-driven geriatric research

Older adults are characterized by profound clinical heterogeneity. When designing and delivering interventions, there exist multiple approaches to account for heterogeneity. We present the results of a systematic review of data-driven, personalized interventions in older adults, which serves as a use case to distinguish the conceptual and methodologic differences between individualized intervention delivery and precision health-derived interventions. We define individualized interventions as those where all participants received the same parent intervention, modified on a case-by-case basis and using an evidence-based protocol, supplemented by clinical judgment as appropriate, while precision health-derived interventions are those that tailor care to individuals whereby the strategy for how to tailor care was determined through data-driven, precision health analytics. We discuss how their integration may offer new opportunities for analytics-based geriatric medicine that accommodates individual heterogeneity but allows for more flexible and resource-efficient population-level scaling.

Comparing an in-person workshop and a postal Delphi survey for involving health service users in health care and health research prioritization

INTRODUCTION

To involve health service users in health care and health research priority setting, different methods exist. Which method is most suitable under which circumstances is unknown. We compared a postal Delphi survey and an in-person workshop to involve health service users in priority settings for rehabilitative care and research in Germany.

METHODS

One hundred and eighty-four former rehabilitants were randomly assigned to a postal Delphi survey (n = 152) or an in-person workshop (n = 32). Two hundred and seventy-six employees in rehabilitation were also invited to the Delphi Survey. The methodological comparison refers only to the sample of rehabilitants. Within each method, the participants agreed on the top 10 priorities for practice improvement and research in rehabilitative care. The priorities were compared descriptively. Participants' satisfaction was measured with the Public and Patient Engagement Evaluation Tool. The usability of both methods was compared based on the effort, time and material costs required for implementation.

RESULTS

Seventy-five former rehabilitants and 41 employees in rehabilitation completed both Delphi survey rounds. Eleven former rehabilitants participated in the in-person workshop. Priorities for practice improvement showed a high degree of overlap between both methods whereas research priorities differed greatly. Participants of the in-person workshop felt significantly better prepared, more listened to and more likely to feel that different views on the topics were discussed. Participants of the Delphi survey expressed difficulties in understanding all survey questions. The Delphi survey was more elaborate in preparation and implementation but caused lower material costs.

CONCLUSION

The differences in research priorities between the two methods could be due to the different samples, differences in the individual interests of participants or differences in the prioritization process. In-person workshops seem to be more appropriate for complex topics, where clarifications of questions and deeper discussions are needed. Delphi surveys seem to be more suitable for easily understandable topics, larger sample sizes and when fewer financial resources are available.

PATIENT OR PUBLIC CONTRIBUTION

The different study phases were supported by employees in rehabilitation and former rehabilitants (e.g., developing study documents, and interpreting results).

Multimorbidity and health-related quality of life among patients attending chronic outpatient medical care in Bahir Dar, Northwest Ethiopia: The application of partial proportional odds model

BACKGROUND

Multimorbidity, the presence of two or more chronic non-communicable diseases (NCDs) in a given person affects all aspects of people's lives. Poor quality of life (QoL) is one of the major consequences of living with multimorbidity. Although healthcare should support multimorbid individuals to achieve a better quality of life, little is known about the effect of multimorbidity on the QoL of patients living with chronic conditions. This study aimed to determine the influence of multimorbidity on QoL among clients attending chronic outpatient medical care in Bahir Dar, Northwest Ethiopia.

METHODOLOGY

A multi-centered facility-based study was conducted among 1440 participants aged 40+ years. Two complementary methods were employed to collect sociodemographic and disease related data. We used the short form (SF-12 V2) instrument to measure quality of life (QoL). The data were analyzed by STATA V.16, and a multivariate partial proportional odds model was fitted to identify covariates associated with quality of life. Statistical significance was considered at p-value <0.05.

PRINCIPAL FINDINGS

Multimorbidity was identified in 54.8% (95% CI = 52.2%-57.4%) of the sample. A significant proportion (33.5%) of the study participants had poor QoL and a quarter (25.8%) of them had moderate QoL. Advanced age, obesity and living with multimorbidity were the factors associated with poor QoL. Conversely, perceived social support and satisfaction with care were the variables positively associated with better QoL.

CONCLUSION

The magnitude of multimorbidity in this study was high and individuals living with multimorbidity had a relatively poorer QoL than those without multimorbidity. Care of people with chronic multiple conditions has to be oriented to the realities of multimorbidity burden and its implication on QoL. It is also imperative to replicate the methods we employed to measure and analyze QoL data in this study for facilitating comparison and further development of the approaches.

Research priority setting related to older adults: a scoping review to inform the Cochrane-Campbell Global Ageing Partnership work programme

OBJECTIVE

To explore and map the findings of prior research priority-setting initiatives related to improving the health and well-being of older adults.

DESIGN

Scoping review.

DATA SOURCES

Searched MEDLINE, EMBASE, AgeLine, CINAHL and PsycINFO databases from January 2014 to 26 April 2021, and the James Lind Alliance top 10 priorities.

ELIGIBILITY CRITERIA

We included primary studies reporting research priorities gathered from stakeholders that focused on ageing or the health of older adults (≥60 years). There were no restrictions by setting, but language was limited to English and French.

DATA EXTRACTION AND SYNTHESIS

We used a modified Reporting Guideline for Priority Setting of Health Research (REPRISE) guideline to assess the transparency of the reported methods. Population-intervention-control-outcome (PICO) priorities were categorised according to their associated International Classification of Health Interventions (ICHI) and International Classification of Functioning (ICF) outcomes. Broad research topics were categorised thematically.

RESULTS

Sixty-four studies met our inclusion criteria. The studies gathered opinions from various stakeholder groups, including clinicians (n=56 studies) and older adults (n=35), and caregivers (n=24), with 75% of the initiatives involving multiple groups. None of the included priority-setting initiatives reported gathering opinions from stakeholders located in low-income or middle-income countries. Of the priorities extracted, 272 were identified as broad research topics, while 217 were identified as PICO priorities. PICO priorities that involved clinical outcomes (n=165 priorities) and interventions concerning health-related behaviours (n=59) were identified most often. Broad research topics on health services and systems were identified most often (n=60). Across all these included studies, the reporting of six REPRISE elements was deemed to be critically low.

CONCLUSION

Future priority setting initiatives should focus on documenting a more detailed methodology with all initiatives eliciting opinions from caregivers and older adults to ensure priorities reflect the opinions of all key stakeholder groups.

Advancing clinical trials in nursing homes: A proposed roadmap to success

An effective clinical research effort in nursing homes to address prevention and treatment of COVID-19 faced overwhelming challenges. Under the Health Care Systems Research Network-Older Americans Independence Centers AGING Initiative, a multidisciplinary Stakeholder Advisory Panel was convened to develop recommendations to improve the capability of the clinical research enterprise in US nursing homes. The Panel considered the nursing home as a setting for clinical trials, reviewed the current state of clinical trials in nursing homes, and ultimately developed recommendations for the establishment of a nursing home clinical trials research network that would be centrally supported and administered. This report summarizes the Panel's recommendations, which were developed in alignment with the following core principles: build on available research infrastructure where appropriate; leverage existing productive partnerships of researchers with groups of nursing homes and nursing home corporations; encompass both efficacy and effectiveness clinical trials; be responsive to a broad range of stakeholders including nursing home residents and their care partners; be relevant to an expansive range of clinical and health care delivery research questions; be able to pivot as necessary to changing research priorities and circumstances; create a pathway for industry-sponsored research as appropriate; invest in strategies to increase diversity in study populations and the research workforce; and foster the development of the next generation of nursing home researchers.

Psychometric Properties, Feasibility, and Acceptability of the Self-Reported interRAI Check-Up Assessment

OBJECTIVES

To assess the feasibility, acceptability, and psychometric properties of the self-report version of the interRAI Check-Up (CUSR).

DESIGN

Cross-sectional study of participant ratings of item content and difficulty completing the CUSR. Participants were also randomly assigned to complete the assessment by themselves or with help from a lay interviewer.

SETTINGS AND PARTICIPANTS

A total of 184 older adults from diverse backgrounds, served by 6 Canadian organizations in Ontario and Nova Scotia were recruited. Settings ranged from retirement communities for healthy older adults to assisted living facilities.

MEASURES/METHODS

Time to complete the interRAI CUSR was tracked automatically. Participants self-reported on what items they wanted to have modified, added, or deleted. The also rated whether items were embarrassing or difficult to complete. Psychometric properties were examined between the 2 approaches to completion and were benchmarked against existing reports on psychometric properties of clinician-led home care assessments.

RESULTS

The interRAI CUSR takes about 28 minutes to complete with both self-administered and lay interviewer approaches. The convergent validity and reliability of CUSR is comparable to those of clinician-based assessments like the Resident Assessment Instrument-Home Care. Most participants had no difficulty completing the assessment, and none rated the task as very difficult. Poor self-rated health and difficulty with phone use were predictive of any difficult in completing the assessment in a multivariate logistic regression. Most participants reported that CUSR adequately described their health needs, but arthritis, hypertension, and mental health issues were identified as items to be added by participants.

CONCLUSIONS AND IMPLICATIONS

The CUSR is an appropriate, feasible assessment system with good psychometric properties for use with general populations, including primary care, community services, and patient-reported outcome measurement studies. Interoperability with other interRAI assessments makes it an ideal system to use to obtain a longitudinal view of the person's needs over time.

The Combined Burden of Hearing Loss and Cognitive Impairment in a Group Care Setting for Older Adults

Purpose The purpose of the current study is to better characterize the medical and social health characteristics of older adults in a long-term group care setting and consider the impact of the dual burden of hearing loss and cognitive impairment. Method This descriptive analysis of a convenience sample of 160 adults (M _age = 74 years, age range: 59.8-99.7) participating in Program for All-inclusive Care for the Elderly programs in Massachusetts and Rhode Island included data from hearing testing, questionnaires, and medical chart review. Using descriptive statistics, groups are compared across a range of demographic and health variables on the categorical bases of hearing loss and cognitive status. Results Results suggest that hearing loss and cognitive impairment are highly prevalent among this sample of older adults. Forty-three percent of this sample has at least a mild hearing loss in the better hearing ear in addition to cognitive impairment. Descriptive analyses across demographic and health variables suggest there are few differences between those with and without cognitive impairment when compared within degree of hearing loss categories in this convenience sample. Across all participants, there was a high prevalence of other chronic conditions, most notably diabetes (59%), hypertension (90%), cardiovascular disease (80%), and depression (67%). Conclusions In this sample, there were not significant differences on demographic and health variables between the cognitive impairment groups when considered within their degree of hearing loss; however, the prevalence of the dual burden of hearing loss and cognitive impairment in this sample is high. Clinicians serving older adults, especially those accessing group care services, should be cognizant of the high burden of multiple chronic conditions and plan care that can be integrated into a comprehensive approach.

Beneficial Effects of Physical Activity on Subjects with Neurodegenerative Disease

Studies on the effectiveness of physical exercise to treat and/or prevent mental disorders are essential and particularly appropriate, given the rapid growth of the elderly population and the consequent increase in the prevalence of neurodegenerative diseases. The onset of neurodegenerative diseases is subtle, and progression is irreversible, as there is still no cure capable of stopping them permanently. Therefore, we should not underestimate these diseases and should immediately begin to combine the treatment with physical activity adapted to specific needs. Indeed, it is well known that physical activity has positive effects on mobility, autonomy, and functional capacity, improving not only cognitive functions, but also reducing the risk of developing dementia. Despite several studies in this field, to date there are no specific and effective protocols that promote physical exercise in people with dementia. Based on this evidence, the aim of the present work was to verify whether an adapted physical exercise regimen could promote the maintenance of psychomotor functions in elderly subjects and, therefore, delay the irreversible effects of combinations of dementia and other pathologies associated with aging. Our results clearly show that exercise is very effective in improving psychomotor functions and delaying the progress of neurodegenerative diseases in humans, since we observed that the subjects maintained their cognitive skills after 8 months of physical activity, moreover, two patients presented an amelioration. Based on the results obtained, we recommend that the motor practice, in any chosen form, be considered an integral part of prevention programs based on an active lifestyle in older people. Future studies will be necessary to establish how long lasting the benefits of a specific physical activity are and whether they are enough to delay cognitive decline.

The Metabolomic Underpinnings of Symptom Burden in Patients With Multiple Chronic Conditions

Over 25% of the adult population in the United States suffers from multiple chronic conditions, with numbers continuing to rise. Those with multiple chronic conditions often experience symptoms or symptom clusters that undermine their quality of life and ability to self-manage. Importantly, symptom severity in those with even the same multiple chronic conditions varies, suggesting that the mechanisms driving symptoms in patients with multiple chronic conditions are not fixed but may differ in ways that could make them amenable to targeted interventions. In this manuscript we describe at a metabolic level, the symptom experience of persons with multiple chronic conditions, including how symptoms may synergize or cluster across multiple chronic conditions to augment one's symptom burden. To guide this discussion, we consider the metabolites and metabolic pathways known to span multiple adverse health conditions and associate with severe symptoms of fatigue, depression, and anxiety and their cluster. We also describe how severe versus mild symptoms, and their associated metabolites and metabolic pathways, may vary, depending on the presence of covariates; two of which, sex as a biological variable and the contribution of gut microbiota dysbiosis, are discussed in additional detail. Intertwining metabolomics and symptom science into nursing research, offers the unique opportunity to better understand how the metabolites and metabolic pathways affected in those with multiple chronic conditions may initiate or exacerbate symptom presence within a given individual, ultimately allowing clinicians to develop targeted interventions to improve the health quality of patients their families.

Accelerating the Search for Interventions Aimed at Expanding the Health Span in Humans: The Role of Epidemiology

BACKGROUND

Extensive work in basic and clinical science suggests that biological mechanisms of aging are causally related to the development of disease and disability in late life. Modulation of the biological mechanisms of aging can extend both life span and health span in animal models, but translation to humans has been slow.

METHODS

Summary of workshop proceedings from the 2018-2019 Epidemiology of Aging Workshop hosted by the Intramural Research Program at the National Institute on Aging.

RESULTS

Epidemiologic studies play a vital role to progress in this field, particularly in evaluating new risk factors and measures of biologic aging that may influence health span, as well as developing relevant outcome measures that are robust and relevant for older individuals.

CONCLUSIONS

Appropriately designed epidemiological studies are needed to identify targets for intervention and to inform study design and sample size estimates for future clinical trials designed to promote health span.

Measuring biological aging in humans: A quest

The global population of individuals over the age of 65 is growing at an unprecedented rate and is expected to reach 1.6 billion by 2050. Most older individuals are affected by multiple chronic diseases, leading to complex drug treatments and increased risk of physical and cognitive disability. Improving or preserving the health and quality of life of these individuals is challenging due to a lack of well-established clinical guidelines. Physicians are often forced to engage in cycles of "trial and error" that are centered on palliative treatment of symptoms rather than the root cause, often resulting in dubious outcomes. Recently, geroscience challenged this view, proposing that the underlying biological mechanisms of aging are central to the global increase in susceptibility to disease and disability that occurs with aging. In fact, strong correlations have recently been revealed between health dimensions and phenotypes that are typical of aging, especially with autophagy, mitochondrial function, cellular senescence, and DNA methylation. Current research focuses on measuring the pace of aging to identify individuals who are "aging faster" to test and develop interventions that could prevent or delay the progression of multimorbidity and disability with aging. Understanding how the underlying biological mechanisms of aging connect to and impact longitudinal changes in health trajectories offers a unique opportunity to identify resilience mechanisms, their dynamic changes, and their impact on stress responses. Harnessing how to evoke and control resilience mechanisms in individuals with successful aging could lead to writing a new chapter in human medicine.

Physical Functioning Decline and Mortality in Older Adults With Multimorbidity: Joint Modeling of Longitudinal and Survival Data

Background

Multimorbidity is common among older adults and strongly associated with physical functioning decline and increased mortality. However, the full spectrum of direct and indirect effects of multimorbidity on physical functioning and survival has not been quantified. We aimed to determine the longitudinal relationship of multimorbidity on physical functioning and quantify the impact of multimorbidity and multimorbidity-attributed changes in physical functioning on mortality risk.

Methods

The Health and Retirement Study (HRS) is a nationally representative population-based prospective cohort of adults aged 51 or older. In 2000, participants were interviewed about physician-diagnosed chronic conditions, from which their multimorbidity-weighted index (MWI) was computed. Between 2000 and 2011, participants reported their current physical functioning using a modified Short Form-36. With MWI as a time-varying exposure, we jointly modeled its associations with physical functioning and survival.

Results

The final sample included 74,037 observations from 18,174 participants. At baseline, participants had a weighted mean MWI of 4.6 ± 4.2 (range 0-36.8). During follow-up, physical functioning declined: -1.72 (95% confidence interval [CI] -1.77, -1.67, p < .001) HRS physical functioning units per point MWI in adjusted models. Over follow-up, 6,362 (34%) participants died. Mortality risk increased 8% (hazard ratio 1.08, 95% CI 1.07-1.08, p < .001) per point MWI in adjusted models. Across all population subgroups, MWI was associated with greater physical functioning decline and mortality risk.

Conclusions

Multimorbidity and its associated decline in physical functioning were significantly associated with increased mortality. These associations can be predicted with an easily interpreted and applied multimorbidity index that can better identify and target adults at increased risk for disability and death.

Associations between prevalent multimorbidity combinations and prospective disability and self-rated health among older adults in Europe

Background

Multimorbidity is associated with greater likelihood of disability, health-related quality of life, and mortality, greater than the risk attributable to individual diseases. The objective of this study is to examine the association between unique multimorbidity combinations and prospective disability and poor self-rated health (SRH) in older adults in Europe.

Methods

We conducted a prospective analysis using data from the Survey of Health, Ageing and Retirement in Europe in 2013 and 2015. We used hierarchical models to compare respondents with multiple chronic conditions to healthy respondents and respondents reporting only one chronic condition and made within-group comparisons to examine the marginal contribution of specific chronic condition combinations.

Results

Less than 20% of the study population reported having zero chronic conditions, while 50% reported having at least two chronic conditions. We identified 380 unique disease combinations among people who reported having at least two chronic conditions. Over 35% of multimorbidity could be attributed to five specific multimorbidity combinations, and over 50% to ten specific combinations. Overall, multimorbidity combinations that included high depressive symptoms were associated with increased odds of reporting poor SRH, and increased rates of ADL-IADL disability.

Conclusions

Multimorbidity groups that include high depressive symptoms may be more disabling than combinations that include only somatic conditions. These findings argue for a continued integration of both mental and somatic chronic conditions in the conceptualization of multimorbidity, with important implications for clinical practice and healthcare delivery.

Profiling the hospital-dependent patient in a large academic hospital: Observational study

BACKGROUND

In older patients with acute illness, a condition of "hospital-dependence" may arise: patients get adapted to the hospital care and, once discharged, may experience health status decline, requiring repeated readmissions despite appropriate treatments.

AIMS

The objective of this case-series study was to describe the characteristics of 118 patients (72 F) aged ≥75 (mean 83.7 ± 4.9) who were urgently admitted to our institution at least 4 times in 2015.

METHODS

For each patient and admission, data on multimorbidity (Cumulative Illness Rating Scale Comorbidity Score and Severity Index), frailty (Rockwood Clinical Frailty Scale), functional dependence, functional status, polypharmacy, length of stay and interval between admissions were extrapolated from clinical records. Mortality during the years 2015 and 2016 was assessed on the institutional database.

RESULTS

At the first admission, patients had a high burden of polypharmacy (median number of drugs 8.5, IQR 6-11) and multimorbidity (Comorbidity Score 15.8 ± 4.1, Severity Index 2.9 ± 1.1). However, most (55.5%) were fit or pre-frail according to Clinical Frailty Scale (score 1-4). At multivariate models, Severity Index was significantly correlated with the length of stay (β ± SE 2.23 ± 0.89, p = .01) and readmission interval (β ± SE -22.49 ± 9.27, p = .02). Significantly increasing trends of multimorbidity and disability occurred across admissions. By the end of 2016, 66% of patients had died. Frailty (RR 2.005, 95%CI 1.054-3.814, p = .007) and cancer were the only predictors of mortality.

CONCLUSIONS

Hospital-dependent patients had severe multimorbidity, but exhibited an unexpectedly low prevalence of frailty/disability at baseline, though increasing across admissions. Trends of frailty and multimorbidity are paramount for profiling the hospital-dependence risk.

Symptom Burden and Palliative Care Needs Among High-Risk Veterans With Multimorbidity

CONTEXT

Palliative care research has focused on patients with disease-specific conditions. However, older patients with multimorbidity may have unmet palliative care needs.

OBJECTIVES

We assessed symptom burden and quality of life among veterans with multimorbidity and sought to determine if their bothersome symptoms were addressed and treated in the primary care setting. We sought to identify specific diagnoses that may account for greater symptom burden. We hypothesized that patients with a higher number of diagnoses would experience greater symptom burden and poorer quality of life.

METHODS

We identified veterans at high risk of hospitalization or death using a validated prognostic model. We administered cross-sectional surveys via telephone, The Memorial Symptom Assessment Scale-Short Form and Veterans RAND 12, to randomly selected patients in primary care in the VA Health Care System from May to December 2015. We assessed if their most bothersome symptom was addressed and treated during their most recent visit. Regression models identified specific diagnoses accounting for greater symptom burden and patient predictors of high symptom burden and poor quality of life.

RESULTS

Patients (n = 503) reported (10.6 ± 5.5) active symptoms and poor physical quality of life. Patients reported pain and dyspnea as their most bothersome symptoms (n = 145 [29%] and n = 57 [11%], respectively). Most patients acknowledged their clinicians assessed (n = 348 [74%]) and treated (n = 330 [70%]) their most bothersome symptom. Physical symptoms (78%, P < 0.0001) were more likely to be addressed than psychological symptoms (55%, P < 0.001). Patients diagnosed with obesity or depression experienced greater physical symptom burden. Younger patients reported greater symptom severity than older patients (P < 0.01). Younger patients and those with greater multimorbidities reported lower self-perceived quality of health than older patients and those with fewer multimorbidities (P = 0.01 and P < 0.01, respectively).

CONCLUSION

Outpatients with multimorbidity have high symptom burden, unaddressed symptoms, poor quality of life, and unmet palliative care needs. Our findings support standardization of comprehensive symptom assessment and management in primary care for veterans with multimorbidities, which may ameliorate symptoms and improve quality of life.

Priorities for research in multiple conditions in later life (multi-morbidity): findings from a James Lind Alliance Priority Setting Partnership

INTRODUCTION

multiple conditions in later life (multi-morbidity) is a major challenge for health and care systems worldwide, is of particular relevance for older people, but has not (until recently) received high priority as a topic for research. We have identified the top 10 research priorities from the perspective of older people, their carers, and health and social care professionals using the methods of a James Lind Alliance Priority Setting Partnership.

METHODS

in total, 354 participants (162 older people and carers, 192 health professionals) completed a survey and 15 older people and carers were interviewed to produce 96 'unanswered questions'. These were further refined by survey and interviews to a shortlist of 21 topics, and a mix of people aged 80+ living with three or more conditions, carers and health and social care providers to prioritised the top 10.

RESULTS

the key priorities were about the prevention of social isolation, the promotion of independence and physical and emotional well-being. In addition to these broad topics, the process also identified detailed priorities including the role of exercise therapy, the importance of falls (particularly fear of falling), the recognition and management of frailty and Comprehensive Geriatric Assessment.

CONCLUSION

these topics provide a unique perspective on research priorities on multiple conditions in later life and complement existing UK and International recommendations about the optimisation of health and social care systems to deliver essential holistic models of care and the prevention and treatment of multiple co-existing conditions.

Collaborating on Data, Science, and Infrastructure: The 20-Year Journey of the Cancer Research Network

The Cancer Research Network (CRN) is a consortium of 12 research groups, each affiliated with a nonprofit integrated health care delivery system, that was first funded in 1998. The overall goal of the CRN is to support and facilitate collaborative cancer research within its component delivery systems. This paper describes the CRN's 20-year experience and evolution. The network combined its members' scientific capabilities and data resources to create an infrastructure that has ultimately supported over 275 projects. Insights about the strengths and limitations of electronic health data for research, approaches to optimizing multidisciplinary collaboration, and the role of a health services research infrastructure to complement traditional clinical trials and large observational datasets are described, along with recommendations for other research consortia.

Patterns of Co-Occurrence of Chronic Disease Among Older Adults in Tokyo, Japan

Introduction

Multimorbidity, the co-occurrence of 2 or more disorders in a patient, can complicate treatment planning and affect health outcomes. Improvements in prevention and management strategies for patients with 3 or more or more co-occurring chronic diseases requires an understanding of the epidemiology of common 3-way disease patterns and their interactions. Our study aimed to describe these common 3-way disease patterns and examine the factors associated with the co-occurrence of 3 or more diseases in elderly Japanese patients.

Methods

We included all Japanese citizens aged 75 or older living in Tokyo who used medical care between September 2013 and August 2014 (N = 1,311,116) in our analysis. The 15 most common 3-way patterns of 22 target diseases according to sex and age were identified from among all possible combinations by using an anonymized medical claims database. We examined the associations of sociodemographic characteristics and health care use with the presence of 1 or 2 co-occurring diseases and 3 or more co-occurring diseases by using multinomial logistic regression.

Results

Approximately 65% of patients had 3 or more co-occurring diseases. The most common 3-way pattern was hypertension, coronary heart disease, and peptic ulcer disease in men (12.4%) and hypertension, dyslipidemia, and peptic ulcer disease in women (12.8%). The prevalence of 3 or more diseases was positively associated with men, patients aged 85 to 90, the use of home medical care services, the number of outpatient facilities visited, and hospital admissions.

Conclusion

The common 3-way disease patterns and multimorbidity factors identified in our study may facilitate the recognition of high-risk patients and support the development of clinical guidelines for multimorbidity.

A Person-Centered Approach to Poststroke Care: The COMprehensive Post-Acute Stroke Services Model

Many individuals who have had a stroke leave the hospital without postacute care services in place. Despite high risks of complications and readmission, there is no standard in the United States for postacute stroke care after discharge home. We describe the rationale and methods for the development of the COMprehensive Post-Acute Stroke Services (COMPASS) care model and the structure and quality metrics used for implementation. COMPASS, an innovative, comprehensive extension of the TRAnsition Coaching for Stroke (TRACS) program, is a clinician-led quality improvement model providing early supported discharge and transitional care for individuals who have had a stroke and have been discharged home. The effectiveness of the COMPASS model is being assessed in a cluster-randomized pragmatic trial in 41 sites across North Carolina, with a recruitment goal of 6,000 participants. The COMPASS model is evidence based, person centered, and stakeholder driven. It involves identification and education of eligible individuals in the hospital; telephone follow-up 2, 30, and 60 days after discharge; and a clinic visit within 14 days conducted by a nurse and advanced practice provider. Patient and caregiver self-reported assessments of functional and social determinants of health are captured during the clinic visit using a web-based application. Embedded algorithms immediately construct an individualized care plan. The COMPASS model's pragmatic design and quality metrics may support measurable best practices for postacute stroke care.

Multimorbidity in Chronic Conditions: Public Primary Care Patients in Four Greater Mekong Countries

The aim of this study was to explore the prevalence, pattern, and social determinants of chronic conditions multimorbidity among chronic disease primary care patients in four Greater Mekong countries (Cambodia, Myanmar, Thailand, and Vietnam). In a cross-sectional survey, chronic disease patients accessing primary care were recruited if they had been diagnosed with any of 21 chronic conditions in the past 12 months, and were interviewed with a structured questionnaire on anxiety, depression, alcohol use, tobacco use, dietary behaviour, physical activity, and quality of life. The sample included 6236 public primary care patients (32.8% men and 67.2% women), with a mean age of 53.0 years (SD = 16.8). From 21 chronic conditions, the three most common were hypertension (37.4%), depression (34.4%), and digestive diseases (32.0%). In all, 27.4% had one chronic condition, 28.6% had two, 22.4% had three, and 21.6% had four or more chronic conditions. The percentage with the highest comorbidity was depression (47.3%), hypertension (43.4%), and digestive diseases (34.1%). The highest mean multimorbidity reported was for mental illness (4.44), kidney disease (4.11), and Parkinson’s disease (4.10), and the lowest multimorbidity for epilepsy (2.43) and cancer (2.80). Compared to those who had only one chronic condition, being male, older age, lower education, and lower quality of life were associated with having two and three or more chronic conditions. Multimorbidity is a prevalent problem among chronic condition primary care patients—a finding with implications for health care delivery, management, and research.
