Preventive interventions to improve older people's health outcomes: systematic review and meta-analysis

BACKGROUND

Systematic reviews of preventive, non-disease-specific primary care trials for older people often report effects according to what is thought to be the intervention's active ingredient.

AIM

To examine the effectiveness of preventive primary care interventions for older people and to identify common components that contribute to intervention success.

DESIGN AND SETTING

A systematic review and meta-analysis of 18 randomised controlled trials (RCTs) published in 22 publications from 2009 to 2019.

METHOD

A search was conducted in PubMed, MEDLINE, Embase, Web of Science, CENTRAL, CINAHL, and the Cochrane Library. Inclusion criteria were: sample mainly aged ≥65 years; delivered in primary care; and non-disease-specific interventions. Exclusion criteria were: non-RCTs; primarily pharmacological or psychological interventions; and where outcomes of interest were not reported. Risk of bias was assessed using the original Cochrane tool. Outcomes examined were healthcare use including admissions to hospital and aged residential care (ARC), and patient-reported outcomes including activities of daily living (ADLs) and self-rated health (SRH).

RESULTS

Many studies had a mix of patient-, provider-, and practice-focused intervention components (13 of 18 studies). Studies included in the review had low-to-moderate risk of bias. Interventions had no overall benefit to healthcare use (including admissions to hospital and ARC) but higher basic ADL scores were observed (standardised mean difference [SMD] 0.21, 95% confidence interval [CI] = 0.01 to 0.40) and higher odds of reporting positive SRH (odds ratio [OR] 1.17, 95% CI = 1.01 to 1.37). When intervention effects were examined by components, better patient-reported outcomes were observed in studies that changed the care setting (SMD for basic ADLs 0.21, 95% CI = 0.01 to 0.40; OR for positive SRH 1.17, 95% CI = 1.01 to 1.37), included educational components for health professionals (SMD for basic ADLs 0.21, 95% CI = 0.01 to 0.40; OR for positive SRH 1.27, 95% CI = 1.05 to 1.55), and provided patient education (SMD for basic ADLs 0.28, 95% CI = 0.09 to 0.48). Additionally, admissions to hospital in intervention participants were fewer by 23% in studies that changed the care setting (incidence rate ratio [IRR] 0.77, 95% CI = 0.63 to 0.95) and by 26% in studies that provided patient education (IRR 0.74, 95% CI = 0.56 to 0.97).

CONCLUSION

Preventive primary care interventions are beneficial to older people's functional ability and SRH but not other outcomes. To improve primary care for older people, future programmes should consider delivering care in alternative settings, for example, home visits and phone contacts, and providing education to patients and health professionals as these may contribute to positive outcomes.

Pragmatic Delphi study aimed at determining practical components for a tool designed to assist Dutch primary care-givers in opioid deprescribing for non-cancer pain

BACKGROUND

Over the past decades, opioid prescriptions have increased in the Netherlands. The Dutch general practitioners' guideline on pain was recently updated and now aims to reduce opioid prescriptions and high-risk opioid use for non-cancer pain. The guideline, however, lacks practical measures for implementation.

OBJECTIVE

This study aims to determine practical components for a tool that should assist Dutch primary care prescribers and implements the recently updated guideline to reduce opioid prescriptions and high-risk use.

METHODS

A modified Delphi approach was used. The practical components for the tool were identified based on systematic reviews, qualitative studies, and Dutch primary care guidelines. Suggested components were divided into Part A, containing components designed to reduce opioid initiation and stimulate short-term use, and Part B, containing components designed to reduce opioid use among patients on long-term opioid treatment. During three rounds, a multidisciplinary panel of 21 experts assessed the content, usability, and feasibility of these components by adding, deleting, and adapting components until consensus was reached on the outlines of an opioid reduction tool.

RESULTS

The resulting Part A consisted of six components, namely education, opioid decision tree, risk assessment, agreements on dosage and duration of use, guidance and follow-up, and interdisciplinary collaboration. The resulting Part B consisted of five components, namely education, patient identification, risk assessment, motivation, and tapering.

CONCLUSIONS

In this pragmatic Delphi study, components for an opioid reduction tool for Dutch primary care-givers are identified. These components need further development, and the final tool should be tested in an implementation study.

Accuracy of physicians' intuitive risk estimation in the diagnostic management of pulmonary embolism: an individual patient data meta-analysis

BACKGROUND

In patients clinically suspected of having pulmonary embolism (PE), physicians often rely on intuitive estimation ("gestalt") of PE presence. Although shown to be predictive, gestalt is criticized for its assumed variation across physicians and lack of standardization.

OBJECTIVES

To assess the diagnostic accuracy of gestalt in the diagnosis of PE and gain insight into its possible variation.

METHODS

We performed an individual patient data meta-analysis including patients suspected of having PE. The primary outcome was diagnostic accuracy of gestalt for the diagnosis of PE, quantified as risk ratio (RR) between gestalt and PE based on 2-stage random-effect log-binomial meta-analysis regression as well as gestalts' sensitivity and specificity. The variability of these measures was explored across different health care settings, publication period, PE prevalence, patient subgroups (sex, heart failure, chronic lung disease, and items of the Wells score other than gestalt), and age.

RESULTS

We analyzed 20 770 patients suspected of having PE from 16 original studies. The prevalence of PE in patients with and without a positive gestalt was 28.8% vs 9.1%, respectively. The overall RR was 3.02 (95% CI, 2.35-3.87), and the overall sensitivity and specificity were 74% (95% CI, 68%-79%) and 61% (95% CI, 53%-68%), respectively. Although variation was observed across individual studies (I2, 90.63%), the diagnostic accuracy was consistent across all subgroups and health care settings.

CONCLUSION

A positive gestalt was associated with a 3-fold increased risk of PE in suspected patients. Although variation was observed across studies, the RR of gestalt was similar across prespecified subgroups and health care settings, exemplifying its diagnostic value for all patients suspected of having PE.

The Role of a Composite Fitness Score in the Association Between Low-Density Cholesterol and All-Cause Mortality in Older Adults: An Individual Patient Data Meta-Analysis

BACKGROUND

In the general population, an increase in low-density lipoprotein cholesterol (LDL-C) predicts higher cardiovascular disease risk, and lowering LDL-C can prevent cardiovascular disease and reduces mortality risk. Interestingly, in cohort studies that include very old populations, no or inverse associations between LDL-C and mortality have been observed. This study aims to investigate whether the association between LDL-C and mortality in the very old is modified by a composite fitness score.

METHODS

A 2-stage meta-analysis of individual participant data from the 5 observational cohort studies. The composite fitness score was operationalized by performance on a combination of 4 markers: functional ability, cognitive function, grip strength, and morbidity. We pooled hazard ratios (HR) from Cox proportional-hazards models for 5-year mortality risk for a 1 mmol/L increase in LDL-C. Models were stratified by high/low composite fitness score.

RESULTS

Composite fitness scores were calculated for 2 317 participants (median 85 years, 60% females participants), of which 994 (42.9%) had a high composite fitness score, and 694 (30.0%) had a low-composite fitness score. There was an inverse association between LDL-C and 5-year mortality risk (HR 0.87 [95% CI: 0.80-0.94]; p < .01), most pronounced in participants with a low-composite fitness score (HR 0.85 [95% CI: 0.75-0.96]; p = .01), compared to those with a high composite fitness score (HR = 0.98 [95% CI: 0.83-1.15]; p = .78), the test for subgroups differences was not significant.

CONCLUSIONS

In this very old population, there was an inverse association between LDL-C and all-cause mortality, which was most pronounced in participants with a low-composite fitness scores.

Towards optimal use of antithrombotic therapy of people with cancer at the end of life: A research protocol for the development and implementation of the SERENITY shared decision support tool

BACKGROUND

Even though antithrombotic therapy has probably little or even negative effects on the well-being of people with cancer during their last year of life, deprescribing antithrombotic therapy at the end of life is rare in practice. It is often continued until death, possibly resulting in excess bleeding, an increased disease burden and higher healthcare costs.

METHODS

The SERENITY consortium comprises researchers and clinicians from eight European countries with specialties in different clinical fields, epidemiology and psychology. SERENITY will use a comprehensive approach combining a realist review, flash mob research, epidemiological studies, and qualitative interviews. The results of these studies will be used in a Delphi process to reach a consensus on the optimal design of the shared decision support tool. Next, the shared decision support tool will be tested in a randomised controlled trial. A targeted implementation and dissemination plan will be developed to enable the use of the SERENITY tool across Europe, as well as its incorporation in clinical guidelines and policies. The entire project is funded by Horizon Europe.

RESULTS

SERENITY will develop an information-driven shared decision support tool that will facilitate treatment decisions regarding the appropriate use of antithrombotic therapy in people with cancer at the end of life.

CONCLUSIONS

We aim to develop an intervention that guides the appropriate use of antithrombotic therapy, prevents bleeding complications, and saves healthcare costs. Hopefully, usage of the tool leads to enhanced empowerment and improved quality of life and treatment satisfaction of people with advanced cancer and their care givers.

Anticholinergic burden measures, symptoms, and fall-associated risk in older adults with polypharmacy: Development and validation of a prognostic model

BACKGROUND

Anticholinergic burden has been associated with adverse outcomes such as falls. To date, no gold standard measure has been identified to assess anticholinergic burden, and no conclusion has been drawn on which of the different measure algorithms best predicts falls in older patients from general practice. This study compared the ability of five measures of anticholinergic burden to predict falls. To account for patients' individual susceptibility to medications, the added predictive value of typical anticholinergic symptoms was further quantified in this context.

METHODS AND FINDINGS

To predict falls, models were developed and validated based on logistic regression models created using data from two German cluster-randomized controlled trials. The outcome was defined as "≥ 1 fall" vs. "no fall" within a 6-month follow-up period. Data from the RIME study (n = 1,197) were used in model development, and from PRIMUM (n = 502) for external validation. The models were developed step-wise in order to quantify the predictive ability of anticholinergic burden measures, and anticholinergic symptoms. In the development set, 1,015 patients had complete data and 188 (18.5%) experienced ≥ 1 fall within the 6-month follow-up period. The overall predictive value of the five anticholinergic measures was limited, with neither the employed anticholinergic variable (binary / count / burden), nor dose-dependent or dose-independent measures differing significantly in their ability to predict falls. The highest c-statistic was obtained using the German Anticholinergic Burden Score (0.73), whereby the optimism-corrected c-statistic was 0.71 after interval validation using bootstrapping and 0.63 in the external validation. Previous falls and dizziness / vertigo had the strongest prognostic value in all models.

CONCLUSIONS

The ability of anticholinergic burden measures to predict falls does not appear to differ significantly, and the added value they contribute to risk classification in fall-prediction models is limited. Previous falls and dizziness / vertigo contributed most to model performance.

Vascular disease and apathy symptoms in the very old: A cross-sectional and longitudinal meta-analysis of individual participant data

OBJECTIVES

Previous findings suggest a vascular foundation underlying apathy, but transdiagnostic and prospective evidence on vascular apathy is scarce. This study examines the association between vascular disease and the presence and development of apathy symptoms in the very old.

METHODS

Four cohorts of the Towards Understanding Longitudinal International older People Studies (TULIPS)-consortium were included in a two-staged, individual participant data meta-analysis using generalized linear mixed models. Vascular disease was defined as a history of any clinical atherosclerotic pathology (angina pectoris, myocardial infarction, intermittent claudication, transient ischemic attack, stroke or related surgeries) and was related to apathy symptoms as repeatedly measured by the Geriatric Depression Scale (GDS-3A ≥2) over a maximum of 5 years.

RESULTS

Of all 1868 participants (median age 85 years old), 53.9% had vascular disease and 44.3% experienced apathy symptoms. Participants with vascular disease had a 76% higher risk of apathy symptoms at baseline (odds ratio (OR) 1.76, 95% confidence interval (CI) 1.32-2.35), irrespective of depressive symptoms and only partially explained by stroke. Conversely, there was no association of vascular disease with the occurrence of apathy symptoms longitudinally, both in those with apathy at baseline (OR 1.00, 95% CI 0.84-1.20) and without (OR 0.96, 95% CI 0.84-1.09).

CONCLUSIONS

Vascular disease in the very old is associated with apathy symptoms cross-sectionally, but not proven longitudinally, independent of depressive symptoms. These findings query a vascular cause underlying apathy symptoms. However, the consistency of our cross-sectional findings in direction and magnitude across the TULIPS-consortium do emphasize international relevance of the interplay of vascular factors and apathy in advanced age, which meaning needs further unravelling.

Self-perceived functioning and (instrumental) activities of daily living questionnaires after a hip fracture: Do they tell the same story?

BACKGROUND

(Instrumental) activities of daily living ((I)ADL) questionnaires are often used as a measure of functioning for different purposes. Depending on the purpose, a measurement of functioning that includes subjective patient perspectives can be relevant. However, it is unclear to what extent (I)ADL instruments capture self-perceived functioning.

OBJECTIVE

Explore what functioning means to older persons after a hip fracture and assess the extent to which (I)ADL instruments align with self-perceived functioning.

DESIGN

Qualitative interview study with framework analysis.

SETTING

Prospective cohort study on recovery after a hip fracture among older persons in a hospital in a large city in the west of the Netherlands.

SUBJECTS

Eighteen home-dwelling older persons (≥70 years) who had a hip fracture 6-12 months ago.

METHODS

Telephone interviews about functioning before and after the hip fracture were coded and analysed using the framework method.

RESULTS

The activities mentioned by participants to be part of their self-perceived functioning could be split into activities necessary to maintain the desired level of independence, and more personal activities that were of value to participants. Both the 'independence activities' and the 'valued activities' mentioned went beyond the activities included in (I)ADL questionnaires. Due to various coping strategies, limitations in activities that are measured in the (I)ADL questionnaires did not necessarily lead to worse self-perceived functioning.

CONCLUSION

Self-perceived functioning differs from functioning measured with (I)ADL questionnaires in the items included and the weighing of limitations in activities. Thus, (I)ADL instruments alone are not enough to measure functioning from the perspective of the older person.

Disentangling the varying associations between systolic blood pressure and health outcomes in the very old: an individual patient data meta-analysis

OBJECTIVES

While randomized controlled trials have proven the benefits of blood pressure (BP) lowering in participating octogenarians, population-based observational studies suggest an association between low systolic blood pressure (SBP) and faster overall decline. This study investigates the effects of BP-lowering treatment, a history of cardiovascular diseases (CVD), and cognitive and physical fitness on the associations between SBP and health outcomes in the very old.

METHODS

Five cohorts from the Towards Understanding Longitudinal International older People Studies (TULIPS) consortium were included in a two-step individual participant data meta-analysis (IPDMA). We pooled hazard ratios (HR) from Cox proportional-hazards models for 5-year mortality and estimates of linear mixed models for change in cognitive and functional decline. Models were stratified by BP-lowering treatment, history of CVD, Mini-Mental State Examination scores, grip strength (GS) and body mass index (BMI).

RESULTS

Of all 2480 participants (59.9% females, median 85 years), median baseline SBP was 149 mmHg, 64.3% used BP-lowering drugs and 47.3% had a history of CVD. Overall, higher SBP was associated with lower all-cause mortality (pooled HR 0.91 [95% confidence interval 0.88-0.95] per 10 mmHg). Associations remained irrespective of BP-lowering treatment, history of CVD and BMI, but were absent in octogenarians with above-median MMSE and GS. In pooled cohorts, SBP was not associated with cognitive and functional decline.

CONCLUSION

While in the very old with low cognitive or physical fitness a higher SBP was associated with a lower all-cause mortality, this association was not evident in fit octogenarians. SBP was not consistently associated with cognitive and functional decline.

Declining daily functioning as a prelude to a hip fracture in older persons-an individual patient data meta-analysis

BACKGROUND

Daily functioning is known to decline after a hip fracture, but studies of self-reported functioning before the fracture suggest this decline begins before the fracture.

OBJECTIVE

Determine whether change in functioning in the year before a hip fracture in very old (80+) differs from change in those without a hip fracture.

DESIGN

Two-stage individual patient data meta-analysis including data from the Towards Understanding Longitudinal International older People Studies (TULIPS)-consortium.

SETTING

Four population-based longitudinal cohorts from the Netherlands, New Zealand and the UK.

SUBJECTS

Participants aged 80+ years.

METHODS

Participants were followed for 5 years, during which (instrumental) activities of daily living [(I)ADL] scores and incident hip fractures were registered at regular intervals. Z-scores of the last (I)ADL score and the change in (I)ADL in the year before a hip fracture were compared to the scores of controls, adjusted for age and sex.

RESULTS

Of the 2,357 participants at baseline, the 161 who sustained a hip fracture during follow-up had a worse (I)ADL score before the fracture (0.40 standard deviations, 95% CI 0.19 to 0.61, P = 0.0002) and a larger decline in (I)ADL in the year before fracture (-0.11 standard deviations, 95% CI -0.22 to 0.004, P = 0.06) compared to those who did not sustain a hip fracture.

CONCLUSIONS

In the very old a decline in daily functioning already starts before a hip fracture. Therefore, a hip fracture is a sign of ongoing decline and what full recovery is should be seen in light of the pre-fracture decline.

The effects of single and a combination of determinants of anaemia in the very old: results from the TULIPS consortium

Background and objectives

Nutritional deficiencies, renal impairment and chronic inflammation are commonly mentioned determinants of anaemia. The aim of this study was to investigate the effects of these determinants, singly and in combination, on anaemia in the very old.

Method

The TULIPS Consortium consists of four population-based studies in oldest-old individuals: Leiden 85-plus Study, LiLACS NZ, Newcastle 85+ study, and TOOTH. Five selected determinants (iron, vitamin B12, and folate deficiency; low estimated glomerular filtration rate (eGFR); and high C-reactive protein (CRP)) were summed. This sum score was used to investigate the association with the presence and onset of anaemia (WHO definition). The individual study results were pooled using random-effects models.

Results

In the 2216 participants (59% female, 30% anaemia) at baseline, iron deficiency, low eGFR and high CRP were individually associated with the presence of anaemia. Low eGFR and high CRP were individually associated with the onset of anaemia.

In the cross-sectional analyses, an increase per additional determinant (adjusted OR 2.10 (95% CI 1.85–2.38)) and a combination of ≥2 determinants (OR 3.44 (95% CI 2.70–4.38)) were associated with the presence of anaemia. In the prospective analyses, an increase per additional determinant (adjusted HR 1.46 (95% CI 1.24–1.71)) and the presence of ≥2 determinants (HR 1.95 (95% CI 1.40–2.71)) were associated with the onset of anaemia.

Conclusion

Very old adults with a combination of determinants of anaemia have a higher risk of having, and of developing, anaemia. Further research is recommended to explore causality and clinical relevance.

Primary Care Variation in Rates of Unplanned Hospitalizations, Functional Ability, and Quality of Life of Older People

PURPOSE

To investigate variability in older people's outcomes according to general practitioner (GP) and practice characteristics in New Zealand and the Netherlands.

METHODS

We used data from 2 primary care-based, cluster-randomized, controlled trials to separately fit mixed models of unplanned admission rates, functional ability, and quality of life (QOL) and examine variation according to GP- and practice-level characteristics after adjusting for participant-level characteristics. For the New Zealand sample (n = 3,755 aged 75+ years in 60 practices), we modeled 36-month unplanned admission rates, Nottingham Extended Activities of Daily Living (NEADL) scale, and QOL domain ratings from the brief version of the World Health Organization Quality of Life assessment tool. For the Netherlands sample (n = 3,141 aged 75+ years in 59 practices), we modeled 12-month unplanned admission rates, Groningen Activity Restriction Scale scores, and EuroQOL 5 dimensions (EQ-5D) summary index.

RESULTS

None of the GP or practice characteristics were significantly associated with rates of unplanned admissions in the New Zealand sample, but we found greater rates of admission in larger practices (incidence rate ratio [IRR], 1.45; 95% CI, 1.15-1.81) and practices staffed with a practice nurse (IRR, 1.74; 95% CI, 1.20-2.52) in the Netherlands sample. In both samples, differences were consistently small where there were significant associations with function (range, -0.26 to 0.19 NEADL points in the New Zealand sample; no associations in the Netherlands sample) and QOL (range, -1.64 to 0.97 QOL points in New Zealand; -0.01 EQ-5D points in the Netherlands).

CONCLUSIONS

In the absence of substantial differences in older people's function and QOL, it remains unclear whether intriguing GP- or practice-related variations in admission rates represent low- or high-quality practice.

Coded diagnoses from general practice electronic health records are a feasible and valid alternative to self-report to define diabetes cases in research

AIMS

To examine the feasibility and validity of obtaining International Classification of Primary Care (ICPC)-coded diagnoses of diabetes mellitus (DM) from general practice electronic health records for case definition in epidemiological studies, as alternatives to self-reported DM.

METHODS

The Netherlands Epidemiology of Obesity study is a population-based cohort study of 6671 persons aged 45-65 years at baseline, included between 2008-2012. Data from electronic health records were collected between 2012-2014. We defined a reference standard using diagnoses, prescriptions and consultation notes and investigated its agreement with ICPC-coded diagnoses of DM and self-reported DM.

RESULTS

After a median follow-up of 1.8 years, data from 6442 (97%) participants were collected. With the reference standard, 506 participants (79/1000 person-years) were classified with prevalent DM at baseline and 131 participants (11/1000 person-years) were classified with incident DM during follow-up. The agreement of prevalent DM between self-report and the reference standard was 98% (kappa 0.86), the agreement between ICPC-coded diagnoses and the reference standard was 99% (kappa 0.95). The agreement of incident DM between ICPC-coded diagnoses and the reference standard was >99% (kappa 0.92).

CONCLUSIONS

ICPC-coded diagnoses of DM from general practice electronic health records are a feasible and valid alternative to self-reported diagnoses of DM.

Predicting negative health outcomes in older general practice patients with chronic illness: Rationale and development of the PROPERmed harmonized individual participant data database

The prevalence of multimorbidity and polypharmacy increases significantly with age and are associated with negative health consequences. However, most current interventions to optimize medication have failed to show significant effects on patient-relevant outcomes. This may be due to ineffectiveness of interventions themselves but may also reflect other factors: insufficient sample sizes, heterogeneity of population. To address this issue, the international PROPERmed collaboration was set up to obtain/synthesize individual participant data (IPD) from five cluster-randomized trials. The trials took place in Germany and The Netherlands and aimed to optimize medication in older general practice patients with chronic illness. PROPERmed is the first database of IPD to be drawn from multiple trials in this patient population and setting. It offers the opportunity to derive prognostic models with increased statistical power for prediction of patient-relevant outcomes resulting from the interplay of multimorbidity and polypharmacy. This may help patients from this heterogeneous group to be stratified according to risk and enable clinicians to identify patients that are likely to benefit most from resource/time-intensive interventions. The aim of this manuscript is to describe the rationale behind PROPERmed collaboration, characteristics of the included studies/participants, development of the harmonized IPD database and challenges faced during this process.

Are Anticholinergic Symptoms a Risk Factor for Falls in Older General Practice Patients With Polypharmacy? Study Protocol for the Development and Validation of a Prognostic Model

Background: Cumulative anticholinergic exposure, also known as anticholinergic burden, is associated with a variety of adverse outcomes. However, studies show that anticholinergic effects tend to be underestimated by prescribers, and anticholinergics are the most frequently prescribed potentially inappropriate medication in older patients. The grading systems and drugs included in existing scales to quantify anticholinergic burden differ considerably and do not adequately account for patients’ susceptibility to medications. Furthermore, their ability to link anticholinergic burden with adverse outcomes such as falls is unclear. This study aims to develop a prognostic model that predicts falls in older general practice patients, to assess the performance of several anticholinergic burden scales, and to quantify the added predictive value of anticholinergic symptoms in this context.

Methods: Data from two cluster-randomized controlled trials investigating medication optimization in older general practice patients in Germany will be used. One trial (RIME, n = 1,197) will be used for the model development and the other trial (PRIMUM, n = 502) will be used to externally validate the model. A priori, candidate predictors will be selected based on a literature search, predictor availability, and clinical reasoning. Candidate predictors will include socio-demographics (e.g. age, sex), morbidity (e.g. single conditions), medication (e.g. polypharmacy, anticholinergic burden as defined by scales), and well-being (e.g. quality of life, physical function). A prognostic model including sociodemographic and lifestyle-related factors, as well as variables on morbidity, medication, health status, and well-being, will be developed, whereby the prognostic value of extending the model to include additional patient-reported symptoms will be also assessed. Logistic regression will be used for the binary outcome, which will be defined as “no falls” vs. “≥1 fall” within six months of baseline, as reported in patient interviews.

Discussion: As the ability of different anticholinergic burden scales to predict falls in older patients is unclear, this study may provide insights into their relative importance as well as into the overall contribution of anticholinergic symptoms and other patient characteristics. The results may support general practitioners in their clinical decision-making and in prescribing fewer medications with anticholinergic properties.

Anaemia and physical and mental health in the very old: An individual participant data meta-analysis of four longitudinal studies of ageing

OBJECTIVE

To determine the physical and mental health of very old people (aged 80+) with anaemia.

METHODS

Individual level meta-analysis from five cohorts of octogenarians (n = 2,392): LiLACS NZ Māori, LiLACS NZ non-Māori, Leiden 85-plus Study, Newcastle 85+ Study, and TOOTH. Mixed models of change in functional ability, cognitive function, depressive symptoms, and self-rated health over time were separately fitted for each cohort. We combined individual cohort estimates of differences according to the presence of anaemia at baseline, adjusting for age at entry, sex, and time elapsed. Combined estimates are presented as differences in standard deviation units (i.e. standardised mean differences-SMDs).

RESULTS

The combined prevalence of anaemia was 30.2%. Throughout follow-up, participants with anaemia, on average, had: worse functional ability (SMD -0.42 of a standard deviation across cohorts; CI -0.59,-0.25); worse cognitive scores (SMD -0.27; CI -0.39,-0.15); worse depression scores (SMD -0.20; CI -0.31,-0.08); and lower ratings of their own health (SMD -0.36; CI -0.47,-0.25). Differential rates of change observed were: larger declines in functional ability for those with anaemia (SMD -0.12 over five years; CI -0.21,-0.03) and smaller mean difference in depression scores over time between those with and without anaemia (SMD 0.18 over five years; CI 0.05,0.30).

CONCLUSION

Anaemia in the very old is a common condition associated with worse functional ability, cognitive function, depressive symptoms, and self-rated health, and a more rapid decline in functional ability over time. The question remains as to whether anaemia itself contributes to worse outcomes or is simply a marker of chronic diseases and nutrient deficiencies.

End-of-Life Care Preferences of Older Patients with Multimorbidity: A Mixed Methods Systematic Review

Unpredictable disease trajectories make early clarification of end-of-life (EoL) care preferences in older patients with multimorbidity advisable. This mixed methods systematic review synthesizes studies and assesses such preferences. Two independent reviewers screened title/abstracts/full texts in seven databases, extracted data and used the Mixed Methods Appraisal Tool to assess risk of bias (RoB). We synthesized findings from 22 studies (3243 patients) narratively and, where possible, quantitatively. Nineteen studies assessed willingness to receive life-sustaining treatments (LSTs), six, the preferred place of care, and eight, preferences regarding shared decision-making processes. When unspecified, 21% of patients in four studies preferred any LST option. In three studies, fewer patients chose LST when faced with death and deteriorating health, and more when treatment promised life extension. In 13 studies, 67% and 48% of patients respectively were willing to receive cardiopulmonary resuscitation and mechanical ventilation, but willingness decreased with deteriorating health. Further, 52% of patients from three studies wished to die at home. Seven studies showed that unless incapacitated, most patients prefer to decide on their EoL care themselves. High non-response rates meant RoB was high in most studies. Knowledge of EoL care preferences of older patients with multimorbidity increases the chance such care will be provided.

Older individuals' views on their personal screening results for complex health problems: a qualitative study

Background

Providing older persons with information about their health status may increase their involvement in their own health and enhance self-management. However, we need a better understanding of how older persons view their personal results after completing a screening questionnaire on complex health, of their (lack of) motivation and their subsequent action.

Methods

In this qualitative study community-dwelling older persons (≥80 years, n = 13) who completed a screening questionnaire on complex health problems were interviewed regarding their perception of the results, the actions they considered taking and their personal motivations. Data were analysed thematically (qualitative content analyses).

Results

Participants expressed interest in feedback, as an objective questionnaire might substantiate their own views regarding their personal health. They were mostly unsurprised by the results and/or had already taken precautions and were therefore not inclined to undertake additional action. They admitted difficulty with and appreciated advice from a professional regarding preparation of an action plan. Unexpected negative results would lead them to discuss matters with family and/or their general practitioner, provided they had a good relationship with their GP.

Conclusion

Older people were interested in direct feedback regarding their screening questionnaire results and in subsequent advice on possible additional measures. General practices could consider inviting older persons to complete a screening questionnaire and discuss activities and personal goals. This information could serve to better shape future interventions aimed at increasing self-management amongst older persons.

Cost-utility and cost-effectiveness analysis of a clinical medication review focused on personal goals in older persons with polypharmacy compared to usual care: Economic evaluation of the DREAMeR study

AIMS

The ageing society may lead to increasing healthcare expenditure. A clinical medication review (CMR) could potentially reduce costs. The aim of this study is to perform a cost-utility and cost-effectiveness analysis from a societal perspective of a patient-centred CMR.

METHODS

A trial-based cost-utility and cost-effectiveness analysis was performed as part of the DREAMeR study, a pragmatic controlled trial that randomised patients aged ≥70 years using at least seven drugs to either CMR or usual care. Over six months, healthcare consumption and drug use were collected to estimate costs, and effects were collected in terms of quality-adjusted life years (QALYs) measured with EQ-5D-5 L and EQ-VAS and as reduced health-related complaints with impact on patients' daily lives.

RESULTS

The total mean costs per patient (n = 588) over six months were €4,189 ± 6,596 for the control group (n = 294) and €4,008 ± 6,678 for the intervention group (n = 294), including estimated intervention costs of €199 ± 67, which resulted in a mean incremental total cost savings of €181 for the intervention group compared to the control group. Compared to the control group, for the intervention group, the mean incremental QALYs over six months were: -0.00217 measured with EQ-5D and 0.003 measured with EQ-VAS. The incremental effect of reduced health-related complaints with impact was -0.34. There was a likelihood of >90% that the intervention was cost-saving.

CONCLUSIONS

The benefits of a patient-centred CMR were inconsistent with no benefits on HR-QoL measured with EQ-5D-5 L and small benefits on HR-QoL measured with EQ-VAS and health-related complaints with impact on patients' daily lives. Additionally, a CMR could potentially be cost saving from a societal perspective.

Recommendations of older adults on how to use the PROM 'TOPICS-MDS' in healthcare conversations: A Delphi study

In shared decision making, the exploration of preferred personal health outcomes is important. Patient-reported outcome measures (PROMs) provide input for discussions between patients and healthcare professionals. The Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS) PROM is a multidimensional questionnaire on the physical and mental health and wellbeing of older adults. This study investigates how the TOPICS-MDS could be used in individual healthcare conversations. We explored views of older adults regarding 1) whether the health domains they want to discuss are included in the TOPICS-MDS and 2) the comprehensibility of the TOPICS-MDS for healthcare conversations with older adults. A three-round Delphi study was conducted. A total of 57 older adults participated in the study, the mean (SD) age was 71.5 (8.5) years, and 78.9% of the participants were female. The participants were divided into four panels based on educational level and cultural background. We used online questionnaires and focus groups. Consensus was pre-defined to be the point when ≥75% of the participants agreed that a domain was important or very important (scored on a 5-point Likert scale). The inter-expert agreement was computed for Round 1 and 3 with Kendall's W. Round 2 was a focus-group. Qualitative data were analyzed by content analysis. Older adults considered 'functional limitations', 'emotional wellbeing', 'social functioning' and 'quality of life' to be important domains of the TOPICS-MDS to discuss in healthcare conversations. The participants added 'coping with stress', 'dealing with health conditions and the effects on life' as extra domains for healthcare conversations. Challenges regarding the comprehensibility of the TOPICS-MDS included difficult words and lengthy or sensitive questions. Questions that included multiple topics were difficult to understand. The TOPICS-MDS covers the domains of life that older adults value as important to discuss with healthcare professionals, and two additional domains were identified. For older adults with a low level of education or a culturally diverse background, the TOPICS-MDS needs to be adjusted for comprehensibility.

Validation and impact of a simplified clinical decision rule for diagnosing pulmonary embolism in primary care: design of the PECAN prospective diagnostic cohort management study

INTRODUCTION

Combined with patient history and physical examination, a negative D-dimer can safely rule-out pulmonary embolism (PE). However, the D-dimer test is frequently false positive, leading to many (with hindsight) 'unneeded' referrals to secondary care. Recently, the novel YEARS algorithm, incorporating flexible D-dimer thresholds depending on pretest risk, was developed and validated, showing its ability to safely exclude PE in the hospital environment. Importantly, this was accompanied with 14% fewer computed tomographic pulmonary angiography than the standard, fixed D-dimer threshold. Although promising, in primary care this algorithm has not been validated yet.

METHODS AND ANALYSIS

The PECAN (Diagnosing Pulmonary Embolism in the context of Common Alternative diagNoses in primary care) study is a prospective diagnostic study performed in Dutch primary care. Included patients with suspected acute PE will be managed by their general practitioner according to the YEARS diagnostic algorithm and followed up in primary care for 3 months to establish the final diagnosis. To study the impact of the use of the YEARS algorithm, the primary endpoints are the safety and efficiency of the YEARS algorithm in primary care. Safety is defined as the proportion of false-negative test results in those not referred. Efficiency denotes the proportion of patients classified in this non-referred category. Additionally, we quantify whether C reactive protein measurement has added diagnostic value to the YEARS algorithm, using multivariable logistic and polytomous regression modelling. Furthermore, we will investigate which factors contribute to the subjective YEARS item 'PE most likely diagnosis'.

ETHICS AND DISSEMINATION

The study protocol was approved by the Medical Ethical Committee Utrecht, the Netherlands. Patients eligible for inclusion will be asked for their consent. Results will be disseminated by publication in peer-reviewed journals and presented at (inter)national meetings and congresses.

Changes in patient satisfaction related to their perceived health state during implementation of improved integrated care for older persons

Patient satisfaction with the general practitioner (GP) is lower in older persons with a higher level of complexity of health problems. This study investigates whether, in these older persons, changes in satisfaction with their GP, on receiving improved integrated care, is related to their perceived health state.Using the Integrated Systematic Care for Older People (ISCOPE) trial (aimed at improving person- centered integrated care) this study compared changes in satisfaction with the GP in older persons (aged ≥75 years) with a high level of complex health problems on receiving integrated care, stratified for perceived health state at baseline. Satisfaction with the GP was registered on a 5-point Likert scale. Perceived health state was estimated with the Older Persons and Informal Caregivers Survey-Composite End Point (TOPICS-CEP) at baseline, stratified into 33% percentiles. Differences in satisfaction change between the intervention and usual care/control groups (overall and stratified for perceived health state) are presented by percentages of 'very satisfied' participants and improving or deteriorating 1 or more points on the Likert scale. At baseline, the intervention (n = 151) and control group (n = 603) were mainly female (75%) and living alone (62%); mean age was 83 years. Medical status, perceived health state and characteristics of participants were similar. Overall, at baseline 44.4% of respondents in the intervention group were 'very satisfied' compared with 37.1% at follow-up, (difference -7.3%). In the control group, 'very satisfied' at baseline was 32% and at follow up 29.2% (difference -2.8%). The p-value for this difference in change is 0.56. After stratification for TOPICS-CEP the results were the same. In older persons with a high level of complexity of health problems, implementation of person- centered integrated healthcare did not influence their satisfaction with the GP, also not among those with the highest or lowest perceived health state.

Effects of a clinical medication review focused on personal goals, quality of life, and health problems in older persons with polypharmacy: A randomised controlled trial (DREAMeR-study)

BACKGROUND

Clinical medication reviews (CMRs) are increasingly performed in older persons with multimorbidity and polypharmacy to reduce drug-related problems (DRPs). However, there is limited evidence that a CMR can improve clinical outcomes. Little attention has been paid to patients' preferences and needs. The aim of this study was to investigate the effect of a patient-centred CMR, focused on personal goals, on health-related quality of life (HR-QoL), and on number of health problems.

METHODS AND FINDINGS

This study was a randomised controlled trial (RCT) performed in 35 community pharmacies and cooperating general practices in the Netherlands. Community-dwelling older persons (≥70 years) with polypharmacy (≥7 long-term medications) were randomly assigned to usual care or to receive a CMR. Randomisation was performed at the patient level per pharmacy using block randomisation. The primary outcomes were HR-QoL (assessed with EuroQol [EQ]-5D-5L and EQ-Visual Analogue Scale [VAS]) and number of health problems (such as pain or dizziness), after 3 and 6 months. Health problems were measured with a self-developed written questionnaire as the total number of health problems and number of health problems with a moderate to severe impact on daily life. Between April 2016 and February 2017, we recruited 629 participants (54% females, median age 79 years) and randomly assigned them to receive the intervention (n = 315) or usual care (n = 314). Over 6 months, in the intervention group, HR-QoL measured with EQ-VAS increased by 3.4 points (95% confidence interval [CI] 0.94 to 5.8; p = 0.006), and the number of health problems with impact on daily life decreased by 12% (difference at 6 months -0.34; 95% CI -0.62 to -0.044; p = 0.024) as compared with the control group. There was no significant difference between the intervention group and control group for HR-QoL measured with EQ-5D-5L (difference at 6 months = -0.0022; 95% CI -0.024 to 0.020; p = 0.85) or total number of health problems (difference at 6 months = -0.30; 95% CI -0.64 to 0.054; p = 0.099). The main study limitations include the risk of bias due to the lack of blinding and difficulties in demonstrating which part of this complex intervention (for example, goal setting, extra attention to patients, reducing health problems, drug changes) contributed to the effects that we observed.

CONCLUSIONS

In this study, we observed that a CMR focused on personal goals improved older patients' lives and wellbeing by increasing quality of life measured with EQ-VAS and decreasing the number of health problems with impact on daily life, although it did not significantly affect quality of life measured with the EQ-5D. Including the patient's personal goals and preferences in a medication review may help to establish these effects on outcomes that are relevant to older patients' lives.

Systolic Blood Pressure and Cognitive Decline in Older Adults With Hypertension

PURPOSE

Hypertension trials often exclude patients with complex health problems and lack generalizability. We aimed to determine if systolic blood pressure (SBP) in patients undergoing antihypertensive treatment is associated with 1-year changes in cognitive/daily functioning or quality of life (QoL) in persons aged ≥75 years with or without complex health problems.

METHODS

We analyzed data from a population-based prospective cohort study (Integrated Systematic Care for Older Persons [ISCOPE]) with a 1-year follow-up. Stratified by SBP level in the year before baseline, we used mixed-effects linear regression models to evaluate the change from baseline to 1-year follow-up in outcome measures (Mini-Mental State Examination [MMSE], Groningen Activity Restriction Scale [GARS], and EQ-5D-3L). We adjusted for age, sex, and baseline MMSE/GARS/EQ-5D-3L scores and stratified for complex health problems as a proxy for frailty.

RESULTS

Participant (n = 1,266) age averaged 82.4 (SD 5) years, and 874 (69%) were women. For participants undergoing antihypertensive therapy (1,057; 83.5%) and with SBP <130 mm Hg, crude cognitive decline was 0.90 points MMSE, whereas in those with SBP >150 mm Hg, it was 0.14 points MMSE (ie, 0.76-point less decline; P for trend = .013). Complex health problems modified the association of SBP with cognition; the association was seen in those with antihypertensive treatment (P for trend <.001), not in those without (P for trend = .13). Daily functioning/QoL did not differ across the strata of SBP or antihypertensive treatment.

CONCLUSIONS

Participants aged ≥75 years undergoing antihypertensive treatment, with SBP ≥130 mm Hg compared to <130 mm Hg, showed less cognitive decline after 1 year, without loss of daily functioning or QoL. This effect was strongest in participants with complex health problems. More studies should be conducted to determine if there is a causal relation and to understand the mechanism of the association observed.

Evidence supporting the best clinical management of patients with multimorbidity and polypharmacy: a systematic guideline review and expert consensus

The complexity and heterogeneity of patients with multimorbidity and polypharmacy renders traditional disease-oriented guidelines often inadequate and complicates clinical decision making. To address this challenge, guidelines have been developed on multimorbidity or polypharmacy. To systematically analyse their recommendations, we conducted a systematic guideline review using the Ariadne principles for managing multimorbidity as analytical framework. The information synthesis included a multistep consensus process involving 18 multidisciplinary experts from seven countries. We included eight guidelines (four each on multimorbidity and polypharmacy) and extracted about 250 recommendations. The guideline addressed (i) the identification of the target population (risk factors); (ii) the assessment of interacting conditions and treatments: medical history, clinical and psychosocial assessment including physiological status and frailty, reviews of medication and encounters with healthcare providers highlighting informational continuity; (iii) the need to incorporate patient preferences and goal setting: eliciting preferences and expectations, the process of shared decision making in relation to treatment options and the level of involvement of patients and carers; (iv) individualized management: guiding principles on optimization of treatment benefits over possible harms, treatment communication and the information content of medication/care plans; (v) monitoring and follow-up: strategies in care planning, self-management and medication-related aspects, communication with patients including safety instructions and adherence, coordination of care regarding referral and discharge management, medication appropriateness and safety concerns. The spectrum of clinical and self-management issues varied from guiding principles to specific recommendations and tools providing actionable support. The limited availability of reliable risk prediction models, feasible interventions of proven effectiveness and decision aids, and limited consensus on appropriate outcomes of care highlight major research deficits. An integrated approach to both multimorbidity and polypharmacy should be considered in future guidelines.

Development of a Patient-Reported Outcome Measure for Geriatric Care: The Older Persons and Informal Caregivers Survey Short Form

BACKGROUND

The Older Persons and Informal Caregivers Minimum Data Set (TOPICS-MDS) is a standardized data set that was developed to evaluate the quality of multidimensional geriatric care. There is an inherent need to reduce the number of TOPICS-MDS survey items to core outcomes to allow it to be more easily applied as a patient-reported outcome measure in clinical settings.

OBJECTIVES

To create a TOPICS-short form (TOPICS-SF) and examine its validity.

METHODS

Data in the TOPICS-MDS from persons aged 65 years and older in the Netherlands were used for the following analyses. Multiple linear regression analyses were performed to select the items and to derive domain weights of TOPICS-SF. A priori hypotheses were made on the basis of psychometric properties of the full-length TOPICS-MDS preference-weighted score (TOPICS-CEP). The validity of TOPICS-SF was evaluated by 1) examining the meta-correlation of the TOPICS-SF score with TOPICS-CEP and two quality-of-life measures, that is, the Cantril Ladder score and the EuroQol five-dimensional questionnaire utility index, and 2) performing mixed multiple regression of TOPICS-SF scores across key sociodemographic characteristics.

RESULTS

TOPICS-SF scores were strongly correlated with the TOPICS-CEP (r = 0.96) and had stronger correlation with the EuroQol five-dimensional questionnaire utility index compared with the Cantril Ladder (r = 0.61 and 0.38, respectively). TOPICS-SF scores were higher among older persons who were married, living independently, and having higher levels of education.

CONCLUSIONS

We have developed the 22-item TOPICS-SF and demonstrated its validity, supporting its use as a patient-reported outcome measure in geriatric care.

Wishes and needs of community-dwelling older persons concerning general practice: A qualitative study

INTRODUCTION

Community-dwelling older persons often experience hindering health complaints that disturb daily activities. If general practitioners (GPs) are unaware of such complaints, this could lead to a mismatch in provided care and needed or expected care. In this qualitative study with community-dwelling older persons we investigated how older persons experience hindering health complaints, how they deal with them, and what they expect from their GP.

METHODS

Participants (aged ≥80 years) with pain and/or problems with walking/standing were invited to participate in a (group)interview about hindering health problems and expectations from general practice. Data were analysed using the framework method and results were discussed with a client panel.

RESULTS

Participants experienced various hindering health complaints in addition to pain and/or problems with walking/standing. Complaints affecting social activities were experienced as the most hindering. Participants actively tried to remain independent and, to achieve this, GPs were expected to be involved and be easily accessible. However, they did not expect specific help from their GP for pain or problems with walking/standing. Suggestions for improvement of care from GPs included optimisation of accessibility (continuous availability by telephone), a yearly check including medication review, open communication, and empathy and support during major life events.

CONCLUSIONS

According to older persons with hindering health complaints, GPs could improve their accessibility/relationship with patients by: 1) continuous telephonic availability, 2) initiating regular contact with medication reviews, and 3) initiating support during major life events. This might lower the reported barriers to contact the GP for hindering health complaints.

The effectiveness of functional task exercise and physical therapy as prevention of functional decline in community dwelling older people with complex health problems

Background

A physically active lifestyle in older people contributes to the preservation of good health. We assessed the influence of physiotherapy on daily functioning among community dwelling older people (75+) with complex health problems identified with screening, versus usual care. We also compared functional task exercise (FTE), with problems prioritized by older people, trained in the home environment, versus usual preventive physical therapy (PPT).

Methods

Design: FTE and PPT were compared in a randomized controlled trial (RCT). Both interventions were compared with daily functioning in an observational study: control group.

Setting/Participants: Community-dwelling persons aged ≥75 years with daily activity limitations enlisted in 83 general practices (n = 155).

Interventions: Both intervention groups (FTE, n = 76 and PPT, n = 79) received individual, 30 min treatments. The control group (n = 228) did not get any experimental intervention offered.

Measurements: Groningen Activities of Daily Living Restriction Scale (GARS).

Statistical analyses: Linear Mixed Model analysis, correcting for age, sex, baseline scores and clustering by physiotherapist were used to compare the different groups.

Results

At baseline, 74% percent of the intervention trial group was female vs 79% in the control group. Median ages were 83.9 and 84.7 respectively.

The median baseline GARS-score for the control group was 41.0 (25 and 75 percentile): 35.0; 48.0) and 40.0 (25 and 75 percentile: 32.3; 46.0) for the intervention group (FTE + PPT). The mean change over time was 3.3 (2.5; 4.1) for the control group. Mean difference in change over time between the intervention (FTE + PPT) and the control group was − 2.5 (− 4.3; − 0.6) (p = .009).

Between FTE and PPT the difference in change was − 0.4 (95% CI: -2.3; 3.0, p = 0.795).

Conclusion

An exercise intervention led by physiotherapists may slow down decline in self-reported daily functioning in older persons with daily activity limitations, identified by pro-active case finding.

Effectiveness and cost-effectiveness of proactive and multidisciplinary integrated care for older people with complex problems in general practice: an individual participant data meta-analysis

Purpose

to support older people with several healthcare needs in sustaining adequate functioning and independence, more proactive approaches are needed. This purpose of this study is to summarise the (cost-) effectiveness of proactive, multidisciplinary, integrated care programmes for older people in Dutch primary care.

Methods design

individual patient data (IPD) meta-analysis of eight clinically controlled trials.

Setting

primary care sector.

Interventions

combination of (i) identification of older people with complex problems by means of screening, followed by (ii) a multidisciplinary integrated care programme for those identified.

Main outcome

activities of daily living, i.e. a change on modified Katz-15 scale between baseline and 1-year follow-up.

Secondary outcomes

quality of life (visual analogue scale 0–10), psychological (mental well-being scale Short Form Health Survey (SF)-36) and social well-being (single item, SF-36), quality-adjusted life years (Euroqol-5dimensions-3level (EQ-5D-3L)), healthcare utilisation and cost-effectiveness.

Analysis

intention-to-treat analysis, two-stage IPD and subgroup analysis based on patient and intervention characteristics.

Results

included were 8,678 participants: median age of 80.5 (interquartile range 75.3; 85.7) years; 5,496 (63.3%) women. On the modified Katz-15 scale, the pooled difference in change between the intervention and control group was −0.01 (95% confidence interval −0.10 to 0.08). No significant differences were found in the other patient outcomes or subgroup analyses. Compared to usual care, the probability of the intervention group to be cost-effective was less than 5%.

Conclusion

compared to usual care at 1-year follow-up, strategies for identification of frail older people in primary care combined with a proactive integrated care intervention are probably not (cost-) effective.

Prediction of functional decline in community-dwelling older persons in general practice: a cohort study

BACKGROUND

A first step to offer community-dwelling older persons proactive care is to identify those at risk of functional decline within a year. This study investigates the predictive value of registered information, questionnaire and GP-opinion on functional decline.

METHODS

In this cohort study, embedded within the ISCOPE-trial, participants (≥75 years) completed the ISCOPE-screening questionnaire on four health domains. GPs gave their opinion on vulnerability of participants. Functional status was measured at baseline and 12 months (Groningen Activities Restriction Scale [GARS]). The outcome was functional decline (death, nursing home admission, 10% with greatest functional decline). The predictive value of pre-selected variables (age, sex, polypharmacy, multimorbidity, living situation; GPs' opinion on vulnerability, number of domains with problems [ISCOPE-score]) was compared with the area under the curves (AUC) for logistic regression models.

RESULTS

2018 of the 2211 participants (median age 82.1 years [IQR 78.8-86.5], 68.0% female, median GARS 31 [IQR 24-41]) were visited at 12 months (median GARS 34 [IQR 26-44]). 394 participants (17.8%) had functional decline (148 died, 45 nursing home admissions, 201 with greatest functional decline). The AUC for age and sex was 0.602, increasing to 0.620 (p = 0.029) with polypharmacy, multimorbidity and living situation. The GPs' opinion added more (AUC 0.672, p < 0.001) than the ISCOPE-score (AUC 0.649, p = 0.007). AUC with all variables was 0.686 (p = 0.016), and 0.643 for GPs' opinion alone.

CONCLUSIONS

The GPs' opinion and ISCOPE-score improve this prediction model for functional decline based on readily available variables. GPs could identify older patients for further assessment with their clinical judgement.

The frail older person does not exist: development of frailty profiles with latent class analysis

Background

A fundamental issue in elderly care is targeting those older people at risk and in need of care interventions. Frailty is widely used to capture variations in health risks but there is no general consensus on the conceptualization of frailty. Indeed, there is considerable heterogeneity in the group of older people characterized as frail. This research identifies frailty profiles based on the physical, psychological, social and cognitive domains of functioning and the severity of the problems within these domains.

Methods

This research was a secondary data-analysis of older persons derived from The Older Person and Informal Caregiver Minimum Dataset. Selected respondents were 60 years and older (n = 43,704; 59.6% female). The following variables were included: self-reported health, cognitive functioning, social functioning, mental health, morbidity status, and functional limitations. Using latent class analysis, the population was divided in subpopulations that were subsequently discussed in a focus group with older people for further validation.

Results

We distinguished six frailty profiles: relatively healthy; mild physically frail; psychologically frail; severe physically frail; medically frail and multi-frail. The relatively healthy had limited problems across all domains. In three profiles older people mostly had singular problems in either the physical or psychological domain and the severity of the problems differed. Two remaining profiles were multidimensional with a combination of problems that extended to the social and cognitive domains.

Conclusions

Our research provides an empirical base for meaningful frailty profiles. The profiles showed specific patterns underlying the problems in different domains of functioning. The heterogeneous population of frail older people has differing needs and faces different health issues that should be considered to tailor care interventions. Evaluation research of these interventions should acknowledge the heterogeneity of frailty by profiling.

Deprescribing preventive cardiovascular medication in patients with predicted low cardiovascular disease risk in general practice - the ECSTATIC study: a cluster randomised non-inferiority trial

BACKGROUND

The use of cardiovascular medication for the primary prevention of cardiovascular disease (CVD) is potentially inappropriate when potential risks outweigh the potential benefits. It is unknown whether deprescribing preventive cardiovascular medication in patients without a strict indication for such medication is safe and cost-effective in general practice.

METHODS

In this pragmatic cluster randomised controlled non-inferiority trial, we recruited 46 general practices in the Netherlands. Patients aged 40-70 years who were using antihypertensive and/or lipid-lowering drugs without CVD and with low risk of future CVD were followed for 2 years. The intervention was an attempt to deprescribe preventive cardiovascular medication. The primary outcome was the difference in the increase in predicted (10-year) CVD risk in the per-protocol (PP) population with a non-inferiority margin of 2.5 percentage points. An economic evaluation was performed in the intention-to-treat (ITT) population. We used multilevel (generalised) linear regression with multiple imputation of missing data.

RESULTS

Of 1067 participants recruited between 7 November 2012 and 18 February 2014, 72% were female. Overall, their mean age was 55 years and their mean predicted CVD risk at baseline was 5%. Of 492 participants in the ITT intervention group, 319 (65%) quit the medication (PP intervention group); 135 (27%) of those participants were still not taking medication after 2 years. The predicted CVD risk increased by 2.0 percentage points in the PP intervention group compared to 1.9 percentage points in the usual care group. The difference of 0.1 (95% CI -0.3 to 0.6) fell within the non-inferiority margin. After 2 years, compared to the usual care group, for the PP intervention group, systolic blood pressure was 6 mmHg higher, diastolic blood pressure was 4 mmHg higher and total cholesterol and low-density lipoprotein-cholesterol levels were both 7 mg/dl higher (all P < 0.05). Cost and quality-adjusted life years did not differ between the groups.

CONCLUSIONS

The results of the ECSTATIC study show that an attempt to deprescribe preventive cardiovascular medication in low-CVD-risk patients is safe in the short term when blood pressure and cholesterol levels are monitored after stopping. An attempt to deprescribe medication can be considered, taking patient preferences into consideration.

Unravelling complex primary-care programs to maintain independent living in older people: a systematic overview

OBJECTIVES

Complex interventions are criticized for being a "black box", which makes it difficult to determine why they succeed or fail. Recently, nine proactive primary-care programs aiming to prevent functional decline in older adults showed inconclusive effects. The aim of this study was to systematically unravel, compare, and synthesize the development and evaluation of nine primary-care programs within a controlled trial to further improve the development and evaluation of complex interventions.

STUDY DESIGN AND SETTING

A systematic overview of all written data on the nine proactive primary-care programs was conducted using a validated item list. The nine proactive primary-care programs involved 214 general practices throughout the Netherlands.

RESULTS

There was little or no focus on the (1) context surrounding the care program, (2) modeling of processes and outcomes, (3) intervention fidelity and adaptation, and (4) content and evaluation of training for interventionists.

CONCLUSIONS

An in-depth analysis of the context, modeling of the processes and outcomes, measurement and reporting of intervention fidelity, and implementation of effective training for interventionists is needed to enhance the development and replication of future complex interventions.

Functional Impairment and Risk of Venous Thrombosis in Older Adults

OBJECTIVES

To determine the role of age-specific risk factors for thrombosis in older age, such as functional impairment.

DESIGN

Case-control study.

SETTING

The Age and Thrombosis-Acquired and Genetic risk factors in the Elderly Study, a two-center study conducted in the Netherlands and the United States from 2008 to 2011.

PARTICIPANTS

Individuals aged 70 and older with a first-time deep venous thrombosis in the leg or pulmonary embolism (n = 401) and controls aged 70 and older (n = 431) without a history of thrombosis. Exclusion criteria were active malignancy and severe cognitive disorders.

MEASUREMENTS

The thrombotic risk associated with functional impairment, defined as impairment in two or more activities of daily living (ADLs), impaired mobility (inability to walk outside), sedentary lifestyle (≥20 h/d sleeping or sitting), and low handgrip strength (<15th percentile), was assessed. Odds ratios (ORs) adjusted for age, sex, and study center with 95% confidence intervals (95% CI) and population attributable risks (PAR) were calculated.

RESULTS

Risk of venous thrombosis was 2.9 times greater (OR = 2.9, 95% CI = 1.6-5.3) in individuals with impairment in ADLs, three times as great (OR = 3.0, 95% CI = 1.9-4.7) in those with impaired mobility, four times as great (OR = 4.0, 95% CI = 2.5-6.3) in those with a sedentary life style, and 2.3 times as great (OR = 2.3, 95% CI = 1.5-3.4) in those with weak handgrip strength. PARs were 8% for ADL disability, 13% for inability to walk outside for 15 minutes, 29% for sedentary lifestyle, and 13% for weak hand grip strength.

CONCLUSION

In individuals aged 70 and older, functional impairments are a major risk factor for venous thrombosis. These findings may help providers caring for older people be more aware of venous thrombosis risk.

Treatment duration of febrile urinary tract infection: a pragmatic randomized, double-blind, placebo-controlled non-inferiority trial in men and women

BACKGROUND

In adults with febrile urinary tract infection (fUTI), data on optimal treatment duration in patients other than non-pregnant women without comorbidities are lacking.

METHODS

A randomized placebo-controlled, double-blind, non-inferiority trial among 35 primary care centers and 7 emergency departments of regional hospitals in the Netherlands. Women and men aged ≥ 18 years with a diagnosis of fUTI were randomly assigned to receive antibiotic treatment for 7 or 14 days (the second week being ciprofloxacin 500 mg or placebo orally twice daily). Patients indicated to receive antimicrobial treatment for at least 14 days were excluded from randomization. The primary endpoint was the clinical cure rate through the 10- to 18-day post-treatment visit with preset subgroup analysis including sex. Secondary endpoints were bacteriologic cure rate at 10-18 days post-treatment and clinical cure at 70-84 days post-treatment.

RESULTS

Of 357 patients included, 200 were eligible for randomization; 97 patients were randomly assigned to 7 days and 103 patients to 14 days of treatment. Overall, short-term clinical cure occurred in 85 (90%) patients treated for 7 days and in 94 (95%) of those treated for 14 days (difference -4.5%; 90% CI, -10.7 to 1.7; P _{non-inferiority} = 0.072, non-inferiority not confirmed). In women, clinical cure was 94% and 93% in those treated for 7 and 14 days, respectively (difference 0.9; 90% CI, -6.9 to 8.7, P _{non-inferiority} = 0.011, non-inferiority confirmed) and, in men, this was 86% versus 98% (difference -11.2; 90% CI -20.6 to -1.8, P _superiority = 0.025, inferiority confirmed). The bacteriologic cure rate was 93% versus 97% (difference -4.3%; 90% CI, -9.7 to 1.2, P _{non-inferiority} = 0.041) and the long-term clinical cure rate was 92% versus 91% (difference 1.6%; 90% CI, -5.3 to 8.4; P _{non-inferiority} = 0.005) for 7 days versus 14 days of treatment, respectively. In the subgroups of men and women, long-term clinical cure rates met the criteria for non-inferiority, indicating there was no difference in the need for antibiotic retreatment for UTI during 70-84 days follow-up post-treatment.

CONCLUSIONS

Women with fUTI can be treated successfully with antibiotics for 7 days. In men, 7 days of antibiotic treatment for fUTI is inferior to 14 days during short-term follow-up but it is non-inferior when looking at longer follow-up.

Statin Use and Self-Reported Hindering Muscle Complaints in Older Persons: A Population Based Study

Purpose

Statins are widely used by older persons in primary and secondary prevention of cardiovascular disease. Although serious adverse events are rare, many statin users report mild muscle pain and/or muscle weakness. It’s unclear what impact statins exert on a patient’s daily life. Research on statin related side effects in older persons is relatively scarce. We therefore investigated the relation between statin use and self-reported hindering muscle complaints in older persons in the general population.

Methods

The present research was performed within the Integrated Systematic Care for Older Persons (ISCOPE) study in the Netherlands (Netherlands trial register, NTR1946). All registered adults aged ≥ 75 years from 59 participating practices (n = 12,066) were targeted. Information about the medical history and statin use at baseline and after 9 months was available for 4355 participants from the Electronic Patient Records of the general practitioners. In the screening questionnaire at baseline we asked participants: ‘At the moment, which health complaints limit you the most in your day-to-day life?’ Answers indicating muscle or musculoskeletal complaints were coded as such. No specific questions about muscle complaints were asked.

Results

The participants had a median age of 80.3 (IQR 77.6–84.4) years, 60.8% were female and 28.5% had a history of CVD. At baseline 29% used a statin. At follow-up, no difference was found in the prevalence of self-reported hindering muscle complaints in statin users compared to non-statin users (3.3% vs. 2.5%, OR 1.39, 95% CI 0.94–2.05; P = 0.98). Discontinuation of statin use during follow-up was independent of self-reported hindering muscle complaints.

Conclusion

Based on the present findings, prevalent statin use in this community-dwelling older population is not associated with self-reported hindering muscle complaints; however, the results might be different for incident users.

[Coping strategies of older people with low mood]

BACKGROUND

To gain new insights for support for older people with low mood, we explored the perceptions of 'screenpositive' older people on underlying causes and possible solutions.

DESIGN AND METHOD

We conducted two in-depth interviews with 38 participants (≥77 years) who screened positive for depressive symptoms in general practice. To investigate the influence of the presence of complex health problems, we included 19 persons with and 19 without complex problems. Complex problems were defined as a combination of functional, somatic, psychological or social problems.

RESULTS

All participants used several cognitive, social or practical coping strategies. Four patterns emerged: mastery, acceptance, ambivalence, and need for support. Some participants, especially those with complex problems, were ambivalent about possible interventions.

CONCLUSION

Most older participants perceived their coping strategies as sufficient. General practitioners can support self-management by exploring the (effectiveness of) personal coping strategies, providing information, elaborating on perceptions of risks and discussing alternative options with older persons.

Reporting of patient-centred outcomes in heart failure trials: are patient preferences being ignored?

Older people often suffer from multiple diseases. Therefore, universal cross-disease outcomes (e.g. functional status, quality of life, overall survival) are more relevant than disease-specific outcomes, and a range of potential outcomes are needed for medical decision-making. To assess how patient-relevant outcomes have penetrated randomized controlled trials (RCTs), reporting of these outcomes was reviewed in heart failure trials that included patients with multimorbidity. We systematically reviewed RCTs (Jan 2011–June 2012) and evaluated reported outcomes. Heart failure was chosen as condition of interest as this is common among older patients with multimorbidity. The main outcome was the proportion of RCTs reporting all-cause mortality, all-cause hospital admission, and outcomes in four domains of health, i.e. functional, signs and symptoms, psychological, and social domains. Of the 106 included RCTs, 50 (47 %) reported all-cause mortality and cardiovascular mortality and 29 (27 %) reported all-cause hospitalization and cardiovascular hospitalization. Of all trials, 68 (64 %) measured outcomes in the functional domain, 80 (75 %) in the domain of signs and symptoms, 65 (61 %) in the psychological domain, and 59 (56 %) in the social domain. Disease-specific instruments were more often used than non-disease-specific instruments. This review shows increasing attention for more patient-relevant outcomes; this is promising and indicates more awareness of the importance of a variety of outcomes desirable for patients. However, patients’ individual goal attainments were universally absent. For continued progress in patient-centred care, efforts are needed to develop these outcomes, study their merits and pitfalls, and intensify their use in research.

Problems experienced by informal caregivers with older care recipients with and without cognitive impairment

The care of older persons can have negative impact on the caregiver. The objective of this population-based observational study is to identify problems experienced by informal caregivers, and the extent of related difficulties, in their care of older care-dependent recipients with and without cognitive impairment. Caregivers (n = 2,704) caring for a home-dwelling person aged ≥ 75 years responded to a questionnaire with 23 questions on problems and related difficulties by mail. Prevalence of self-reported problems and related difficulties was calculated. The impact of the problem was estimated by weighing the percentage of problems reported as being difficult against the prevalence of problems. The median number of problems was 12 (range 0–23), with 5 (range 0–23) reported as difficult. Informal caregivers experience a variety of problems, with the impossibility to engage in joint social activities having the highest impact. The impact of problems increased when the care recipient had a cognitive problem.

Overweight can be used as a tool to guide case-finding for cardiovascular risk assessment

BACKGROUND

In general practice, it is too time-consuming to invite all patients for cardiovascular risk assessment.

OBJECTIVE

To examine how many patients with an indication for treatment with cardiovascular medication can be identified by ad hoc case-finding when all patients with overweight/obesity are invited for risk assessment.

METHODS

A cross-sectional analysis of the baseline measurements of the Netherlands Epidemiology of Obesity study, a population-based prospective cohort study in 6673 persons aged 45-65 years. We calculated the proportion of participants with a treatment indication using the risk prediction Systematic COronary Risk Evaluation (SCORE-NL 2011), for lean, overweight and obese participants. Participants with a history of cardiovascular disease, diabetes mellitus or rheumatoid arthritis or using cardiovascular medication were not eligible for ad hoc case-finding because they were already identified as being at risk and/or had been treated.

RESULTS

Of the study population, 30% had already been identified and/or treated with cardiovascular medication and were therefore not eligible for ad hoc case-finding. Of the eligible participants, 47% were lean, 41% overweight and 12% obese. Of the participants with overweight, 12% had a treatment indication and of the participants with obesity, 19% had a treatment indication. Of all participants with a treatment indication 24% were not yet treated. Of all participants with a new treatment indication, 70% had overweight or obesity.

CONCLUSIONS

Of the participants with a treatment indication, 24% were not yet treated. Inviting patients with overweight/obesity for cardiovascular risk assessment may help to detect 70% of these residual patients with a treatment indication.

Advantages and disadvantages of unstructured cardiovascular risk factor screening for follow-up in primary care

BACKGROUND

In contrast to structured, integrated risk assessment in primary care, unstructured risk factor screening outside primary care and corresponding recommendations to consult a general practitioner (GP) are often based on one abnormal value of a single risk factor. This study investigates the advantages and disadvantages of unstructured screening of blood pressure and cholesterol outside primary care.

METHODS

After the baseline visit of the Netherlands Epidemiology of Obesity study (population-based prospective cohort study in persons aged 45-65 years, recruited 2008-2012) all participants received a letter with results of blood pressure and cholesterol, and a recommendation to consult a GP if results were abnormal. Four years after the start of the study, participants received a questionnaire about the follow-up of their results.

RESULTS

The study population consisted of 6343 participants, 48% men, mean age 56 years, mean body mass index 30 kg/m(2). Of all participants 66% had an abnormal result and, of these, 49% had a treatment indication based on the risk estimation system SCORE-NL 2006. Of the 25% of the participants who did not consult a GP, 40% had a treatment indication. Of the participants with an abnormal result 19% were worried, of whom 60% had no treatment indication.

CONCLUSIONS

In this population 51% of the participants with an abnormal result had unnecessarily received a recommendation to consult a GP, and 10% were unnecessarily worried. GPs should be informed about the complete risk assessment, and only participants at intermediate or high risk should receive a recommendation to consult a GP.

Self-Reported Hindering Health Complaints of Community-Dwelling Older Persons: A Cross-Sectional Study

Purpose

Proactive care for community-dwelling older persons targeting self-reported hindering health complaints might prevent a decline in function. We investigated the spectrum of self-reported hindering complaints of community-dwelling older persons, the association with functional outcomes, and help-seeking behavior for these complaints.

Methods

Within the ISCOPE trial, participants (aged ≥75 years) received the ISCOPE screening questionnaire, including the open-ended question “At the moment, which health complaints limit you the most in your day-to-day life?”. After coding the answers with the ICPC-1-NL, we examined the prevalence and the association between the number and type of complaints and functional outcomes (Groningen Activities Restriction Scale, quality of life measured on Cantril’s Ladder, Mini-Mental State Examination, Geriatric Depression Scale-15, and De Jong Gierveld Loneliness Scale). Electronic patient registers were searched for the most reported complaints.

Results

7285 participants (median age: 81.0 years [IQR 77.8–85.3], 38.6% males) reported 13,524 hindering complaints (median 1, range 0–18); 32.7% reported no complaints. Participants mostly reported problems with walking/standing (22.1%), pain (20.8%) or weakness/tiredness (8.5%). These complaints were mentioned in the electronic patient registers in 28.3%, 91.3% and 55.5%, respectively. Higher numbers of hindering complaints were related to poorer scores on the number of domains with problems, Cantril’s Ladder for quality of life, Groningen Activities Restriction Scale, Geriatric Depression Scale, and De Jong Gierveld Loneliness Scale. Self-reported weakness, problems with walking/standing, visual limitations, cognitive problems, dyspnea and back complaints were associated with poorer scores on the number of domains with problems, Groningen Activities Restriction Scale, MMSE or Geriatric Depression Scale.

Conclusion

One third of the participants reported no hindering complaints. Problems with walking/standing, pain, and weakness/tiredness were most reported, but not always found in electronic patient registers. A higher number of, and specific self-reported hindering complaints, were associated with poorer scores on functional outcomes. It may be helpful for general practitioners to ask about these complaints and their influence on daily life.

Change in calculated cardiovascular risk due to guideline revision: A cross-sectional study in the Netherlands

BACKGROUND

Guidelines and accompanying risk charts concerning cardiovascular risk management (CVRM) are regularly revised worldwide.

OBJECTIVE

To evaluate whether revision of the Dutch CVRM guideline has led to the reclassification of patients and, accordingly, to changes in drug recommendations.

METHODS

All medical records (year 2011) of patients aged 40-65 years with no history of cardiovascular disease (CVD) but using antihypertensive and/or lipid-lowering drugs, were selected from the Registration Network of General Practices associated with Leiden University Medical Center. Multiple imputation techniques for missing determinants were used. The individual cardiovascular risk was calculated and the resulting drug recommendation was assessed according to both the 2006 and 2012 versions of the guideline.

RESULTS

In total, 2075 patients were selected, of whom 1248 fulfilled the guideline criteria (systolic blood pressure 115-180 mmHg and total cholesterol/high-density-lipoprotein-cholesterol ratio 3.5-8). According to the 2012 guideline, 58.2% of the patients had low risk and 249 patients (20.0%) shifted to a different risk category. For 150 of these patients (12.0%), this category shift implied a shift in drug recommendation. The probability of shifting in drug recommendation increased with increasing age, cholesterol level, and blood pressure, and by being male.

CONCLUSION

Guideline revision may have important implications: based on identical values for risk factors, according to the latest revision of the Dutch CVRM guideline 20% of patients shifted in risk category and 12% of the patients shifted in drug recommendation.

Clinical features of venous insufficiency and the risk of venous thrombosis in older people

Venous thrombosis is common in older age, with an incidence of 0·5-1% per year in those aged >70 years. Stasis of blood flow is an important contributor to the development of thrombosis and may be due to venous insufficiency in the legs. The risk of thrombosis associated with clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, obtained with a standardized interview was assessed in the Age and Thrombosis Acquired and Genetic risk factors in the Elderly (AT-AGE) study. The AT-AGE study is a case-control study in individuals aged 70 years and older (401 cases with a first-time venous thrombosis and 431 control subjects). We calculated odds ratios (ORs) and corresponding 95% confidence intervals (CI) adjusted for age, sex and study centre. Varicose veins and leg ulcer were associated with a 1·6-fold (95% CI 1·2-2·3) and 3·3-fold increased risk of thrombosis (95% CI 1·6-6·7), respectively, while the risk was increased 3·0-fold (95% CI 2·1-4·5) in the presence of leg oedema. The risk of thrombosis was highest when all three risk factors occurred simultaneously (OR: 10·5; 95% CI 1·3-86·1). In conclusion, clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, are risk factors for venous thrombosis in older people.

Prognostic value of pro-adrenomedullin, procalcitonin and C-reactive protein in predicting outcome of febrile urinary tract infection

Bacterial infections such as febrile urinary tract infection (fUTI) may run a complicated course that is difficult to foretell on clinical evaluation only. Because the conventional biomarkers erythrocyte sedimentation rate (ESR), leucocyte count, C-reactive protein (CRP) and procalcitonin (PCT) have a limited role in the prediction of a complicated course of disease, a new biomarker-plasma midregional pro-adrenomedullin (MR-proADM)-was evaluated in patients with f UTI. We conducted a prospective multicentre cohort study including consecutive patients with f UTI at 35 primary-care centres and eight emergency departments. Clinical and microbiological data were collected and plasma biomarker levels were measured at presentation to the physician. Survival was assessed after 30 days. Of 494 fUTI patients, median age was 67 (interquartile range 49-78) years, 40% were male; two-thirds of them had significant co-existing medical conditions. Median MR-proADM level was 1.42 (interquartile range 0.67-1.57) nM; significantly elevated MR-proADM levels were measured in patients with bacteraemia, those admitted to the intensive care unit, and in 30-day and 90-day non-survivors, compared with patients without these characteristics. The diagnostic accuracy for predicting 30-day mortality in fUTI, reflected by the area-under-the-curve of receiver operating characteristics were: MR-proADM 0.83 (95% CI 0.71-0.94), PCT 0.71 (95% CI 0.56-0.85); whereas CRP, ESR and leucocyte count lacked diagnostic value in this respect. This study shows that MR-proADM assessed on first contact predicts a complicated course of disease and 30-day mortality in patients with fUTI and in this respect has a higher discriminating accuracy than the currently available biomarkers ESR, CRP, PCT and leucocyte count.

Comparing the health state preferences of older persons, informal caregivers and healthcare professionals: a vignette study

Background

The Older Persons and Informal Caregivers Survey—Minimum Dataset (TOPICS-MDS) collects uniform information from research projects funded under the Dutch National Care for the Elderly Programme. To compare the effectiveness of these projects a preference-weighted outcome measure that combined multidimensional TOPICS-MDS outcomes into a composite endpoint (TOPICS-CEP) was developed based on the health state preferences of older persons and informal caregivers.

Objectives

To derive preference weights for TOPICS-CEP’s components based on health state preferences of healthcare professionals and to investigate whether these weights differ between disciplines and differ from those of older persons and informal caregivers.

Materials and Methods

Vignette studies were conducted. Participants assessed the general wellbeing of older persons described in vignettes on a scale (0-10). Mixed linear analyses were used to obtain and compare the preference weights of the eight TOPICS-CEP components: morbidities, functional limitations, emotional wellbeing, pain experience, cognitive problems, social functioning, self-perceived health, and self-perceived quality of life (QOL).

Results

Overall, 330 healthcare professionals, 124 older persons and 76 informal caregivers participated. The preference weights were not significantly different between disciplines. However, the professionals’ preference weights differed significantly from those of older persons and informal caregivers. Morbidities and functional limitations were given more weight by older persons and informal caregivers than by healthcare professionals [difference between preference weights: 0.12 and 0.07] while the opposite was true for pain experience, social functioning, and self-perceived QOL [difference between preference weights: 0.13, 0.15 and 0.26].

Conclusion

It is important to recognize the discrepancies between the health state preferences of various stakeholders to (1) correctly interpret results when studying the effectiveness of interventions in elderly care and (2) establish appropriate healthcare policies. Furthermore, we should strive to include older persons in our decision making process through a shared decision making approach.
