RESUMO
BACKGROUND: Resilience refers to the process in which people function well despite adversity. Persistent severe pain may be considered an adversity in people with lower limb osteoarthritis (LLOA). The objectives of this study are: (1) to identify what proportion of older adults with LLOA and persistent severe pain show good functioning; and (2) to explore predictors of resilience. METHODS: Data from the European Project on OSteoArthritis (EPOSA) were used involving standardized data from six European population-based cohort studies. LLOA is defined as clinical knee and/or hip osteoarthritis. Persistent severe pain is defined as the highest tertile of the pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index both at baseline and follow-up. Resilience is defined as good physical, mental or social functioning at follow-up despite having LLOA with persistent severe pain. RESULTS: In total, 95 (14.9%) out of 638 individuals with LLOA had persistent severe pain. Among these, 10 (11.0%), 54 (57.4%) and 49 (53.8%) had good physical, mental and social functioning, respectively. Only 4 individuals (4.5%) were resilient in all three domains of functioning. Younger age, male sex, higher education, higher mastery, smoking and alcohol use, higher physical activity levels, absence of chronic diseases, and more contacts with friends predicted resilience in one or more domains of functioning. CONCLUSIONS: Few people with LLOA and persistent severe pain showed good physical functioning and about half showed good mental or social functioning. Predictors of resilience differed between domains, and might provide new insights for treatment.

BACKGROUND: Late-life depression is common among older adults living in nursing homes (NHs). Over the last 30 years there has been an increase in the rates of prescription of antidepressant medications across all ages, with the largest rise reported in older adults. This study aimed to describe the pattern of antidepressant medication use among NH residents from 7 European countries and Israel and to examine patient and facilities characteristics that may account for it. METHODS: We conducted a cross-sectional analysis of data from the SHELTER study, an observational longitudinal cohort study that collected comprehensive resident data using the interRAI Long-Term Care Facility instrument in 7 European Countries and Israel. Descriptive statistics were used to examine sample characteristics. Potential correlates of antidepressant medication use were identified using multiple logistic regression modeling. RESULTS: Among 4023 residents entering the study, 32% had depressive symptoms and nearly half of these individuals used antidepressants. Antidepressant medication use varied by country, with a prevalence in the overall sample of 35.6% (n = 1431). Among antidepressant users, 59.9% were receiving selective serotonin reuptake inhibitors (SSRI). The strongest correlates of antidepressant use included reported diagnosis of anxiety, depression, bipolar disorder, pain, falls and high level of social engagement. Age over 85 years, living in facilities located in rural areas and a diagnosis of schizophrenia reduced the likelihood of being prescribed with an antidepressant. CONCLUSIONS: A large proportion of residents in European long-term care facilities receive antidepressant medications. The decision to prescribe antidepressants to NH residents seems to be influenced by both patient and facility characteristics. Future longitudinal studies should evaluate the efficacy and safety of antidepressant use in NHs thus providing evidence for recommendations for clinical practice.

BACKGROUND: Identifying those people at increased risk of early functional decline in activities of daily living (ADL) is essential for initiating preventive interventions. The aim of this study is to develop and validate a clinical prediction model for onset of functional decline in ADL in three years of follow-up in older people of 65-75 years old. METHODS: Four population-based cohort studies were pooled for the analysis: ActiFE-ULM (Germany), ELSA (United Kingdom), InCHIANTI (Italy), LASA (Netherlands). Included participants were 65-75 years old at baseline and reported no limitations in functional ability in ADL at baseline. Functional decline was assessed with two items on basic ADL and three items on instrumental ADL. Participants who reported at least some limitations at three-year follow-up on any of the five items were classified as experiencing functional decline. Multiple logistic regression analysis was used to develop a prediction model, with subsequent bootstrapping for optimism-correction. We applied internal-external cross-validation by alternating the data from the four cohort studies to assess the discrimination and calibration across the cohorts. RESULTS: Two thousand five hundred sixty community-dwelling people were included in the analyses (mean age 69.7 ± 3.0 years old, 47.4% female) of whom 572 (22.3%) reported functional decline at three-year follow-up. The final prediction model included 10 out of 22 predictors: age, handgrip strength, gait speed, five-repeated chair stands time (non-linear association), body mass index, cardiovascular disease, diabetes, chronic obstructive pulmonary disease, arthritis, and depressive symptoms. The optimism-corrected model showed good discrimination with a C statistic of 0.72. The calibration intercept was 0.06 and the calibration slope was 1.05. Internal-external cross-validation showed consistent performance of the model across the four cohorts. CONCLUSIONS: Based on pooled cohort data analyses we were able to show that the onset of functional decline in ADL in three years in older people aged 65-75 years can be predicted by specific physical performance measures, age, body mass index, presence of depressive symptoms, and chronic conditions. The prediction model showed good discrimination and calibration, which remained stable across the four cohorts, supporting external validity of our findings.

BACKGROUND: This study examines the association of both pain severity and within-person pain variability with physical activity (PA) in older adults with osteoarthritis (OA). METHODS: Data from the European Project on OSteoArthritis were used. At baseline, clinical classification criteria of the American College of Rheumatology were used to diagnose OA in older adults (65-85 years). At baseline and 12-18 months follow-up, frequency and duration of participation in the activities walking, cycling, gardening, light and heavy household tasks, and sports activities were assessed with the Longitudinal Aging Study Amsterdam Physical Activity Questionnaire. Physical activity was calculated in kcal/day, based on frequency, duration, body weight and the metabolic equivalent of each activity performed. At baseline and 12-18 months follow-up, pain severity was assessed using the pain subscales of the Western Ontario and McMaster Universities OA Index and the Australian/Canadian Hand OA Index. Within-person pain variability was assessed using two-week pain calendars that were completed at baseline, 6 months follow-up and 12-18 months follow-up. RESULTS: Of all 669 participants, 70.0% were women. Sex-stratified multiple linear regression analyses showed that greater pain severity at baseline was cross-sectionally associated with less PA in women (Ratio = 0.95, 95% CI = 0.90-0.99), but not in men (Ratio = 0.99, 95% CI = 0.85-1.15). The longitudinal analyses showed a statistically significant inverse association between pain severity at baseline and PA at follow-up in women (Ratio = 0.94, 95% CI = 0.89-0.99), but not in men (Ratio = 1.00, 95% CI = 0.87-1.11). Greater pain variability over 12-18 months was associated with more PA at follow-up in men (Ratio = 1.18, 95% CI = 1.01-1.38), but not in women (Ratio = 0.94, 95% CI = 0.86-1.03). CONCLUSIONS: Greater pain severity and less pain variability are associated with less PA in older adults with OA. These associations are different for men and women. The observed sex differences in the various associations should be studied in more detail and need replication in future research.

BACKGROUND: The Australian/Canadian hand Osteoarthritis Index (AUSCAN) and the Western Ontario and McMaster Universities knee and hip Osteoarthritis Index (WOMAC) are the most commonly used clinical tools to manage and monitor osteoarthritis (OA). Few studies have as yet reported longitudinal changes in the AUSCAN index regarding the hand. While there are published data regarding WOMAC assessments of the hip and the knee, the two sites have always evaluated separately. The current study therefore sought to determine the minimal clinically important difference (MCID) in decline in the AUSCAN hand and WOMAC hip/knee physical function scores over 1 year using anchor-based and distribution-based methods. METHODS: The study analysed data collected by the European Project on Osteoarthritis, a prospective observational study investigating six adult cohorts with and without OA by evaluating changes in the AUSCAN and WOMAC physical function scores at baseline and 12-18 months later. Pain and stiffness scores, the performance-based grip strength and walking speed and health-related quality of life measures were used as the study's anchors. Receiver operating characteristic curves and distribution-based methods were used to estimate the MCID in the AUSCAN and WOMAC physical function scores; only the data of those participants who possessed paired (baseline and follow up-measures) AUSCAN and WOMAC scores were included in the analysis. RESULTS: Out of the 1866 participants who were evaluated, 1842 had paired AUSCAN scores and 1845 had paired WOMAC scores. The changes in the AUSCAN physical function score correlated significantly with those in the AUSCAN pain score (r = 0.31). Anchor- and distribution-based approaches converged identifying 4 as the MCID for decline in the AUSCAN hand physical function. Changes in the WOMAC hip/knee physical function score were significantly correlated with changes in both the WOMAC pain score (r = 0.47) and the WOMAC stiffness score (r = 0.35). The different approaches converged identifying two as the MCID for decline in the WOMAC hip/knee physical function. CONCLUSIONS: The most reliable MCID estimates of decline over 1 year in the AUSCAN hand and WOMAC hip/knee physical function scores were 4 and 2 points, respectively.

Time spent out-of-home can increase physical activity (PA) levels. However, the association between the purpose for leaving home and the mode of transport on time out-of-home and PA are not straightforward. In a large sample of community-dwelling older adults (≥65 years), daily walking duration was measured prospectively over 1 week using body-fixed sensors and time-out-of-home questionnaires. Data from 1,277 participants yielded 6,500 full days for analysis. The following statistically significant associations were seen: public transport use increased the time spent out-of-home by 88 min and daily walking duration by 16 min. Social contacts or the use of a car increased the time out-of-home, but decreased PA. Shopping or "going by foot" decreased the time spent out-of-home by 19 and 62 min, respectively, while both increased the daily walking duration by 5 min. The association between time out-of-home and PA (daily walking duration) is strongly dependent on the activity and mode of transport.

Besides its known function as a transport protein for testosterone and other steroid hormones, sex hormone-binding globulin (SHBG) is a biomarker associated with many adverse health effects. The aim of this study was to investigate the association of physical activity with SHBG serum levels in older adults. The physical activity and SHBG values for 1,259 older adults (43.4% female; 56.6% male) with a mean age of 75.6 ± 6.5 years were included in the analysis. The average daily walking duration was 104.2 ± 40.4 (mean ± SD) min. A positive dose-response relationship of daily walking duration with quartiles of SHBG was seen after adjustment for age, sex, history of cardiovascular diseases, diabetes, smoking, γ-glutamyl transferase, and C-reactive protein (p for trend = .010). However, this relationship disappeared after adjustment for body mass index (p for trend = .977). Body mass index seems to be an important determinant of SHBG and a possible confounding factor in the relationship of physical activity and SHBG.

Aging-associated changes in the function of the immune system are referred to as senescent immune remodeling (SIR). Here we review the current understanding on the cellular and molecular mechanisms underlying SIR. We focus on aging-associated changes in T and B cells, and discuss recent evidence supporting the notion that aging of the hematopoietic stem cell (HSC) compartment directly contributes to SIR due to aging-associated alterations in stem cell differentiation. We conclude by outlining strategies to attenuate SIR, including approaches to rejuvenate HSCs, which may open new avenues for targeting SIR in the clinic.

Untreated high blood pressure in old age increases the risk of secondary diseases, especially stroke, coronary heart disease, myocardial infarction and heart failure and should be treated according to the guidelines. For slightly frail people up to the age of 80 years, a systolic blood pressure of 130-139â¯mmâ¯Hg (measured in the doctors surgery) should be the aim. According to the current European guidelines the same values are recommended for those over the age of 80 years but treatment should start at a systolic blood pressure of ≥160â¯mmâ¯Hg. In physically disabled and very frail older people an individually tailored approach is recommended, regardless of age. The authors recommend a target systolic value <150â¯mmâ¯Hg but not below 130/70â¯mmâ¯Hg. In the event of poor tolerance the treatment should be adapted further as necessary. Antihypertensive medication should be selected under the aspects of polypharmacy. In many cases arterial hypertension in old age can be treated in accordance with the guidelines, taking multimorbidity and the interaction of medications into consideration.

OBJECTIVE: Fear of falling (FOF) is an important threat to autonomy. Current interventions to reduce FOF have yielded conflicting results. A possible reason for this discrepancy could be its multicausality. Some risk factors may not have been identified and addressed in recent studies. The last systematic review included studies until 2006. METHODS: To identify additional risk factors for FOF and to test those mentioned previously, we conducted a systematic literature review. Studies examining FOF in community-dwelling older adults between 2006 and October 2013 were screened. RESULTS: Outcomes are summarized with respect to different constructs such as FOF, fall-related self-efficacy/balance confidence, and FOF-related activity restriction. Odds ratios and p values are reported. There is no clear pattern with regard to the different FOF-related constructs studied. The only parameters robustly associated across all constructs were female gender, performance-based and questionnaire-based physical function, the use of a walking aid, and, less robust, a history of falls and poor self-rated health. Conflicting results were identified for depression and anxiety, multiple drugs, and psychotropic drugs. Other potentially modifiable risk factors were only mentioned in one or two studies and warrant further investigation. Parameters with mainly negative results are also presented. CONCLUSION: Only few risk factors identified were robustly associated across all FOF-related constructs and should be included in future studies on FOF. Some newer factors have to be tested again in different cohorts. The comprehensive overview might assist in the conceptualization of future studies.

BACKGROUND AND AIMS: Several tests of physical performance like gait speed or standing balance are part of the geriatric assessment. Measures of physical activity like daily walking duration are more difficult to assess but may be of higher relevance for daily requirements. It is therefore of interest to what extent physical performance measures are associated with physical activity. METHODS: In a cohort study, baseline screening was performed in 1271 community-living people aged 65-90 years from Ulm, Germany. Average daily walking duration was assessed in all participants by accelerometers over a one-week period. Habitual gait speed, 5-Chair-Rise test, standing balance and handgrip strength served as measures of physical performance. The association between measures of physical performance and physical activity was calculated by linear regression analysis. RESULTS: The mean daily walking duration was 104.8 minutes in men and 103.0 minutes in women. A positive relationship between gait speed and walking duration was observed in men and women with low gait speed (≤0.8 m/s) but not in participants above this threshold. Standing balance and hand grip strength were positively and 5-Chair-Rise test inversely related with average daily walking duration. A relationship between hand grip strength and walking duration was only observed in women aged 75 years and more. CONCLUSIONS: Physical performance measures and objectively measured walking duration are related with each other but only a small percentage of the variance of daily walking duration was explained by physical performance measures. Therefore, factors other than physical performance seem to influence daily walking duration to a great extent.

OBJECTIVE: To validate a novel assessment of inpatient physical activity. DESIGN: Prospective cohort study for the evaluation of a novel questionnaire for physical activity in geriatric inpatients. SETTING: German geriatric inpatient rehabilitation unit. PARTICIPANTS: Patients (N=96; 67 [72%] women; median age, 81y) with a variety of main underlying diagnoses, including musculoskeletal diseases, hip fracture, cardiovascular diseases, stroke, and others. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Ceiling and floor effects and administration time were measured. For criterion-related concurrent validity (convergent and discriminative), the Physical Activity in Inpatient Rehabilitation Assessment (PAIR) was administered in parallel to self-rated, proxy-rated, and performance-based measures of physical function at admission. Measurements were repeated at discharge and 4-month follow-up in the home environment, including a standard physical activity questionnaire to determine predictive validity. Spearman correlation coefficients were calculated to describe associations between parameters. Sensitivity to change was estimated using standardized response means (SRMs). RESULTS: Administration time of the PAIR ranged from less than 1 to 4 minutes. Ceiling effects occurred mainly at discharge (5%-14%), and floor effects (5%-11%), at admission. There were no missing values. Associations between convergent and predictive validity measures and functional measures (r=.43-.53, r=.49-.54, respectively) were clearly better when cognition was intact. Discriminative validity expressed as effect sizes ranged from .27 to 1.44. The SRM to describe sensitivity to change was .65 for the total score. CONCLUSIONS: The PAIR is the first validated questionnaire to assess physical activity in geriatric inpatients. It is practical and its validity and sensitivity to change are similar to existing physical activity questionnaires for community-dwelling older persons.

OBJECTIVES: Many studies describing an association of drugs with falls focus mostly on drugs acting in the central nervous system. We aim to analyze the association of all drugs taken with falls in older adults. DESIGN: Prospective population-based study (ActiFE study). SETTING AND PARTICIPANTS: A total of 1377 community-dwelling older adults with complete recording of falls and baseline information on drug intake. METHODS: Negative binomial regression was used to analyze the association of 34 drug classes with a 12-month incidence rate ratio (IRR) of falls adjusting for age, sex, comorbidities, gait speed, balance, chair rise, kidney function, liver disease, and smoking. RESULTS: Participants took a median 3 drugs (interquartile range 1, 5), with 34.5% (n = 469) having ≥5 drugs. The median IRR for a fall per person-year was overall 0.72 [95% confidence interval (CI) 0.60-0.83] and 2.22 (95% CI 1.90-2.53) among those who experienced ≥1 fall. The following drug classes showed significant associations: antiparkinsonian medication [IRR 2.68 (95% CI 1.59-4.51)], thyroid therapy [IRR 1.40 (95% CI 1.08-1.81)], and systemic corticosteroids [IRR 0.33 (95% CI 0.13-0.81)]. Among fall-risk-increasing drugs only antiepileptics [IRR 2.16 (95% CI 1.10-4.24)] and urologicals [IRR 2.47 (95% CI 1.33-4.59)] were associated with falls in those participants without a prior fall history at baseline. CONCLUSION AND IMPLICATIONS: Additional drug classes, such as antiparkinsonian medication, thyroid therapy, and systemic corticosteroids, might be associated with falls in older adults, possibly representing pharmacological effects on the musculoskeletal and central nervous systems. Further evaluations in larger study populations are recommended.

BACKGROUND: Through the increasingly aging population, the health care system is confronted with various challenges such as expanding health care costs. To manage these challenges, mobile apps may represent a cost-effective and low-threshold approach to support older adults. OBJECTIVE: This systematic review aimed to evaluate the quality, characteristics, as well as privacy and security measures of mobile apps for older adults in the European commercial app stores. METHODS: In the European Google Play and App Store, a web crawler systematically searched for mobile apps for older adults. The identified mobile apps were evaluated by two independent reviewers using the German version of the Mobile Application Rating Scale. A correlation between the user star rating and overall rating was calculated. An exploratory regression analysis was conducted to determine whether the obligation to pay fees predicted overall quality. RESULTS: In total, 83 of 1217 identified mobile apps were included in the analysis. Generally, the mobile apps for older adults were of moderate quality (mean 3.22 [SD 0.68]). Four mobile apps (5%) were evidence-based; 49% (41/83) had no security measures. The user star rating correlated significantly positively with the overall rating (r=.30, P=.01). Obligation to pay fees could not predict overall quality. CONCLUSIONS: There is an extensive quality range within mobile apps for older adults, indicating deficits in terms of information quality, data protection, and security precautions, as well as a lack of evidence-based approaches. Central databases are needed to identify high-quality mobile apps.
RESUMO
OBJECTIVE: To investigate factors that together with hand or hip/knee osteoarthritis (OA) could contribute to functional decline over a year's time in elderly individuals. METHODS: The data of 1,886 individuals between ages 65 and 85 years in a prospective, observational population-based study with 12-18 months of follow-up in the context of the European Project on Osteoarthritis were analyzed. The outcome measures were self-reported hand and hip/knee functional decline, evaluated using a minimum clinically important difference of 4 on the Australian/Canadian Hand OA Index and of 2 on the Western Ontario and McMaster Universities Osteoarthritis Index hip/knee physical function subscales, both normalized to 0-100. Using regression models adjusted for sex, age, country, and education level, the baseline factors considered were clinical hand or hip/knee OA, pain, analgesic/antiinflammatory medications, comorbidities, social isolation, income, walking time, grip strength, physical activity time, and medical/social care. RESULTS: After a year, 453 participants were identified as having worse hand functionality and 1,389 as not worse. Hand OA, anxiety, walking time, and grip strength were risk factors for hand functional decline; pain was a confounder of the effect of hand OA. Analgesic/antiinflammatory medications mediated the combined effect of hip/knee OA plus pain on functional decline in the 554 individuals classified as having worse hip/knee functionality and the 1,291 persons who were not worse. Peripheral artery disease, obesity, and cognitive impairment were other baseline risk factors. CONCLUSION: Study findings showed that together with emotional status and chronic physical and cognitive conditions, OA affects hand and hip/knee functional decline.

BACKGROUND: A large number of studies have demonstrated a positive effect of increased physical activity (PA) on various health outcomes. In all large geriatric studies, however, PA has only been assessed by interview-based instruments which are all subject to substantial bias. This may represent one reason why associations of PA with geriatric syndromes such as falls show controversial results. The general aim of the Active-Ulm study was to determine the association of accelerometer-based physical activity with different health-related parameters, and to study the influence of this standardized objective measure of physical activity on health- and disability-related parameters in a longitudinal setting. METHODS: We have set up an observational cohort study in 1500 community dwelling older persons (65 to 90 years) stratified by age and sex. Addresses have been obtained from the local residents registration offices. The study is carried out jointly with the IMCA--Respiratory Health Survey in the Elderly implemented in the context of the European project IMCA II. The study has a cross-sectional part (1) which focuses on PA and disability and two longitudinal parts (2) and (3). The primary information for part (2) is a prospective 1 year falls calendar including assessment of medication change. Part (3) will be performed about 36 months following baseline. Primary variables of interest include disability, PA, falls and cognitive function. Baseline recruitment has started in March 2009 and will be finished in April 2010.All participants are visited three times within one week, either at home or in the study center. Assessments included interviews on quality of life, diagnosed diseases, common risk factors as well as novel cognitive tests and established tests of physical functioning. PA is measured using an accelerometer-based sensor device, carried continuously over a one week period and accompanied by a prospective activity diary. DISCUSSION: The assessment of PA using a high standard accelerometer-based device is feasible in a large population-based study. The results obtained from cross-sectional and longitudinal analyses will shed light on important associations between PA and various outcomes and may provide information for specific interventions in older people.

OBJECTIVE: The evaluation of rehabilitation success as measured by different tools is becoming increasingly important in terms of time and money allocation. We wanted to know whether functional change in the first week predicts subsequent improvement in a geriatric inpatient rehabilitation clinic. DESIGN: Observational longitudinal study. SETTING: Geriatric inpatient rehabilitation clinic in Germany. SUBJECTS: One hundred and sixty-one inpatients (117 women) with a median age of 82 years, capable of walking at baseline. MAIN MEASURES: Weekly assessments of physical function were performed from admission until three weeks later. We used a self-rated tool (the function component of the Short Form - Late Life Function and Disability Index), a proxy-rated tool (the Barthel Index) and a performance-based tool (gait speed). We set up linear regression models to estimate the predictive capacity of change in physical function within the first week on change in physical function within the following two weeks. RESULTS: Positive correlations were found between functional change within the first week and total change within three weeks. However, correlations of the same periods of change with subsequent change were negative. Correlations were highly significant for both analysis with P-values <0.0001 when the same measures for prediction and outcome were used. Correlations were inconsistent when prediction and outcome were different. CONCLUSIONS: Improvement within the first week of inpatient rehabilitation is negatively correlated with subsequent functional change.

OBJECTIVE: To determine whether there is an association between osteoarthritis (OA) and incident social isolation using data from the European Project on OSteoArthritis (EPOSA) study. DESIGN: Prospective, observational study with 12 to 18 months of follow-up. SETTING: Community dwelling. PARTICIPANTS: Older people living in six European countries. MEASUREMENTS: Social isolation was assessed using the Lubben Social Network Scale and the Maastricht Social Participation Profile. Clinical OA of the hip, knee, and hand was assessed according to American College of Rheumatology criteria. Demographic characteristics, including age, sex, multijoint pain, and medical comorbidities, were assessed. RESULTS: Of the 1967 individuals with complete baseline and follow-up data, 382 (19%) were socially isolated and 1585 were nonsocially isolated at baseline; of these individuals, 222 (13.9%) experienced social isolation during follow-up. Using logistic regression analyses, after adjustment for age, sex, and country, four factors were significantly associated with incident social isolation: clinical OA, cognitive impairment, depression, and worse walking time. Compared to those without OA at any site or with only hand OA, clinical OA of the hip and/or knee, combined or not with hand OA, led to a 1.47 times increased risk of social isolation (95% confidence interval = 1.03-2.09). CONCLUSION: Clinical OA, present in one or two sites of the hip and knee, or in two or three sites of the hip, knee, and hand, increased the risk of social isolation, adjusting for cognitive impairment and depression and worse walking times. Clinicians should be aware that individuals with OA may be at greater risk of social isolation. J Am Geriatr Soc 68:87-95, 2019.

When treating older adults, a main factor to consider is physical frailty. Because specific assessments in clinical trials are frequently lacking, critical appraisal of treatment evidence with respect to functional status is challenging. Our aim was to identify and categorize assessments for functional status given in clinical trials in older adults to allow for a retrospective characterization and indirect comparison of treatment evidence from these cohorts. We conducted 4 separate systematic reviews of randomized and nonrandomized controlled clinical trials in older people with hypertension, diabetes, depression, and dementia. All assessments identified that reflected functional status were analyzed. Assessments were categorized across 4 different functional status levels. These levels span from functionally not impaired, slightly impaired, significantly impaired, to severely impaired/disabled. If available from the literature, cut-offs for these 4 functioning levels were extracted. If not, or if the existing cut-offs did not match the predefined functional levels, cut-off points were defined by an expert group composed of geriatricians, pharmacists, pharmacologists, neurologists, psychiatrists, and epidemiologists using a patient-centered approach. We identified 51 instruments that included measures of functional status. Although some of the assessments had clearly defined cut-offs across our predefined categories, many others did not. In most cases, no cut-offs existed for slightly impaired or severely impaired older adults. Missing cut-offs or values to adjust were determined by the expert group and are presented as described. The functional status assessments that were identified and operationalized across 4 functional levels could now be used for a retrospective characterization of functional status in randomized controlled trials and observational studies. Allocated categories only serve as approximations and should be validated head-to-head in future studies. Moreover, as general standard, upcoming studies involving older adults should include and explicitly report functional impairment as a baseline characteristic of all participants enrolled.
