Promotion of health in older people: a randomised controlled trial of health risk appraisal in British general practice

BACKGROUND there is inadequate evidence to support currently formulated NHS strategies to achieve health promotion and preventative care in older people through broad-based screening and assessment in primary care. The most extensively evaluated delivery instrument for this purpose is Health Risk Appraisal (HRA). This article describes a trial using HRA to evaluate the effect on health behaviour and preventative-care uptake in older people in NHS primary care. METHODS a randomised controlled trial was undertaken in three London primary care group practices. Functionally independent community-dwelling patients older than 65 years (n = 2,503) received a self-administered Health Risk Appraisal for Older Persons (HRA-O) questionnaire leading to computer-generated individualised written feedback to participants and general practitioners (GPs), integrated into practice information-technology (IT) systems. All primary care staff received training in preventative health in older people. The main outcome measures were self-reported health behaviour and preventative care uptake at 1-year follow-up. RESULTS of 2,503 individuals randomised, 2,006 respondents (80.1%) (intervention, n = 940, control n = 1,066) were available for analysis. Intervention group respondents reported slightly higher pneumococcal vaccination uptake and equivocal improvement in physical activity levels compared with controls. No significant differences were observed for any other categories of health behaviour or preventative care measures at 1-year follow-up. CONCLUSIONS HRA-O implemented in this way resulted in minimal improvement of health behaviour or uptake of preventative care measures in older people. Supplementary reinforcement involving contact by health professionals with patients over and above routine clinical encounters may be a prerequisite to the effectiveness of IT-based delivery systems for health promotion in older people.

A Randomized Trial of Effects of Health Risk Appraisal Combined With Group Sessions or Home Visits on Preventive Behaviors in Older Adults

BACKGROUND To explore effects of a health risk appraisal for older people (HRA-O) program with reinforcement, we conducted a randomized controlled trial in 21 general practices in Hamburg, Germany. METHODS Overall, 2,580 older patients of 14 general practitioners trained in reinforcing recommendations related to HRA-O-identified risk factors were randomized into intervention (n = 878) and control (n = 1,702) groups. Patients (n = 746) of seven additional matched general practitioners who did not receive this training served as a comparison group. Patients allocated to the intervention group, and their general practitioners, received computer-tailored written recommendations, and patients were offered the choice between interdisciplinary group sessions (geriatrician, physiotherapist, social worker, and nutritionist) and home visits (nurse). RESULTS Among the intervention group, 580 (66%) persons made use of personal reinforcement (group sessions: 503 [87%], home visits: 77 [13%]). At 1-year follow-up, persons in the intervention group had higher use of preventive services (eg, influenza vaccinations, adjusted odds ratio 1.7; 95% confidence interval 1.4-2.1) and more favorable health behavior (eg, high fruit/fiber intake, odds ratio 2.0; 95% confidence interval 1.6-2.6), as compared with controls. Comparisons between intervention and comparison group data revealed similar effects, suggesting that physician training alone had no effect. Subgroup analyses indicated favorable effects for HRA-O with personal reinforcement, but not for HRA-O without reinforcement. CONCLUSIONS HRA-O combined with physician training and personal reinforcement had favorable effects on preventive care use and health behavior.

Subgroups of refusers in a disability prevention trial in older adults: Baseline and follow-up analysis

OBJECTIVES This study explored differences between refusers and participants in a longitudinal study with extensive baseline and follow-up information. METHODS Results of a trial comparing 791 participants and 401 community-residing older adults who refused to participate in a study concerning preventive home visits were examined. Information was collected from interviews, insurance records, and government files. RESULTS Despite similarities in terms of age, sex, and self-perceived health at baseline, 3-year follow-up data indicated that refusers had a 1.58-fold higher risk of entering a nursing home than participants. There were additional differences between refusers and participants when refusers were categorized in 4 subgroups based on self-reported reason for refusal (too ill, too healthy, no interest, and other reasons). CONCLUSIONS Future studies should include follow-up data to allow comparisons between refusers and participants and should address the presence of multiple subgroups of refusers.

Age-dependent Decrease in 11β-Hydroxysteroid Dehydrogenase Type 2 (11β-HSD2) Activity in Hypertensive Patients

BACKGROUND The prevalence of arterial hypertension lacking a defined underlying cause increases with age. Age-related arterial hypertension is insufficiently understood, yet known characteristics suggest an aldosterone-independent activation of the mineralocorticoid receptor. Therefore, we hypothesized that 11beta-HSD2 activity is age-dependently impaired, resulting in a compromised intracellular inactivation of cortisol (F) with F-mediated mineralocorticoid hypertension. METHODS Steroid hormone metabolites in 24-h urine samples of 165 consecutive hypertensive patients were analyzed for F and cortisone (E), and their TH-metabolites tetrahydro-F (THF), 5alphaTHF, TH-deoxycortisol (THS), and THE by gas chromatography-mass spectroscopy. Apparent 11beta-HSD2 and 11beta-hydroxylase activity and excretion of F metabolites were assessed. RESULTS In 72 female and 93 male patients aged 18-84 years, age correlated positively with the ratios of (THF + 5alphaTHF)/THE (P = 0.065) and F/E (P < 0.002) suggesting an age-dependent reduction in the apparent 11beta-HSD2 activity, which persisted (F/E; P = 0.020) after excluding impaired renal function. Excretion of F metabolites remained age-independent most likely as a consequence of an age-dependent diminished apparent 11beta-hydroxylase activity (P = 0.038). CONCLUSION Reduced 11beta-HSD2 activity emerges as a previously unrecognized risk factor contributing to the rising prevalence of arterial hypertension in elderly. This opens new perspectives for targeted treatment of age-related hypertension.

Effect of Health Risk Assessment and Counselling on Health Behaviour and Survival in Older People: A Pragmatic Randomised Trial

Background Potentially avoidable risk factors continue to cause unnecessary disability and premature death in older people. Health risk assessment (HRA), a method successfully used in working-age populations, is a promising method for cost-effective health promotion and preventive care in older individuals, but the long-term effects of this approach are unknown. The objective of this study was to evaluate the effects of an innovative approach to HRA and counselling in older individuals for health behaviours, preventive care, and long-term survival. Methods and Findings This study was a pragmatic, single-centre randomised controlled clinical trial in community-dwelling individuals aged 65 y or older registered with one of 19 primary care physician (PCP) practices in a mixed rural and urban area in Switzerland. From November 2000 to January 2002, 874 participants were randomly allocated to the intervention and 1,410 to usual care. The intervention consisted of HRA based on self-administered questionnaires and individualised computer-generated feedback reports, combined with nurse and PCP counselling over a 2-y period. Primary outcomes were health behaviours and preventive care use at 2 y and all-cause mortality at 8 y. At baseline, participants in the intervention group had a mean ± standard deviation of 6.9 ± 3.7 risk factors (including unfavourable health behaviours, health and functional impairments, and social risk factors) and 4.3 ± 1.8 deficits in recommended preventive care. At 2 y, favourable health behaviours and use of preventive care were more frequent in the intervention than in the control group (based on z-statistics from generalised estimating equation models). For example, 70% compared to 62% were physically active (odds ratio 1.43, 95% CI 1.16–1.77, p = 0.001), and 66% compared to 59% had influenza vaccinations in the past year (odds ratio 1.35, 95% CI 1.09–1.66, p = 0.005). At 8 y, based on an intention-to-treat analysis, the estimated proportion alive was 77.9% in the intervention and 72.8% in the control group, for an absolute mortality difference of 4.9% (95% CI 1.3%–8.5%, p = 0.009; based on z-test for risk difference). The hazard ratio of death comparing intervention with control was 0.79 (95% CI 0.66–0.94, p = 0.009; based on Wald test from Cox regression model), and the number needed to receive the intervention to prevent one death was 21 (95% CI 12–79). The main limitations of the study include the single-site study design, the use of a brief self-administered questionnaire for 2-y outcome data collection, the unavailability of other long-term outcome data (e.g., functional status, nursing home admissions), and the availability of long-term follow-up data on mortality for analysis only in 2014. Conclusions This is the first trial to our knowledge demonstrating that a collaborative care model of HRA in community-dwelling older people not only results in better health behaviours and increased use of recommended preventive care interventions, but also improves survival. The intervention tested in our study may serve as a model of how to implement a relatively low-cost but effective programme of disease prevention and health promotion in older individuals.

Reduction of inappropriate medications among older nursing-home residents: a nurse-led, pre/post-design, intervention study

AbstractBackground: Medication-related problems are common in the growing population of older adults and inappropriate prescribing is a preventable risk factor. Explicit criteria such as the Beers criteria provide a valid instrument for describing the rate of inappropriate medication (IM) prescriptions among older adults. Objective: To reduce IM prescriptions based on explicit Beers criteria using a nurse-led intervention in a nursing-home (NH) setting. Study Design: The pre/post-design included IM assessment at study start (pre-intervention), a 4-month intervention period, IM assessment after the intervention period (post-intervention) and a further IM assessment at 1-year follow-up. Setting: 204-bed inpatient NH in Bern, Switzerland. Participants: NH residents aged ≥60 years. Intervention: The intervention included four key intervention elements: (i) adaptation of Beers criteria to the Swiss setting; (ii) IM identification; (iii) IM discontinuation; and (iv) staff training. Main Outcome Measure: IM prescription at study start, after the 4-month intervention period and at 1-year follow-up. Results: The mean±SD resident age was 80.3±8.8 years. Residents were prescribed a mean±SD 7.8±4.0 medications. The prescription rate of IMs decreased from 14.5% pre-intervention to 2.8% post-intervention (relative risk [RR] = 0.2; 95% CI 0.06, 0.5). The risk of IM prescription increased nonstatistically significantly in the 1-year follow-up period compared with post-intervention (RR = 1.6; 95% CI 0.5, 6.1). Conclusions: This intervention to reduce IM prescriptions based on explicit Beers criteria was feasible, easy to implement in an NH setting, and resulted in a substantial decrease in IMs. These results underscore the importance of involving nursing staff in the medication prescription process in a long-term care setting.

Geriatric Pain Measure Short Form: Development and Initial Evaluation

OBJECTIVES: To develop and evaluate a short form of the 24‐item Geriatric Pain Measure (GPM) for use in community‐dwelling older adults.

Social network assessment in community-dwelling older persons: results from a study of three European populations

Background and aims: In clinical practice, the status of living alone is often used as the only measure describing an older person’s social network. We evaluated whether additional use of a brief social network measure provides relevant additional information in relation to social support and engagement. Methods: Cross-sectional survey of 6982 community-dwelling adults 65 years or older living in London, UK; Hamburg, Germany; and Solothurn, Switzerland. Data were collected using the self-administered multidimensional Health Risk Appraisal Questionnaire. Multivariate models were used to analyse adjusted correlations between the two measures of social network (living alone status, risk for social isolation with marginal family and friend network subscales) and potential consequences of inadequate social network (marginal emotional or instrumental support, lack of social engagement). Results: Living alone status was more strongly associated with marginal instrumental support [OR=7.6 (95% CI 6.3, 9.1)] than with marginal emotional support [OR=4.2 (95% CI 3.4, 5.1)], and showed no statistically significant association with lack of social engagement [OR=0.9 (95% CI 0.8, 1.0)]. Risk of social isolation was more strongly related to marginal emotional support [OR=6.6 (95% CI 5.4, 8.0)] than to marginal instrumental support [OR=3.3 (95% CI 2.8, 4.0)], and was moderately related to lack of social engagement [OR=2.9 (95% CI 2.5, 3.4]. Marginal family and friend network subscales showed consistent and unique associations with social support and social engagement. Conclusion: Findings suggest that living alone status and a brief measure of social network identifies distinctive at-risk groups and potential pathways for intervention. Geriatric assessment programs including both social network measures may provide useful information about potentially modifiable social network risks in older persons.

Ein multidimensionaler Fragebogen als Bestandteil eines präventiven geriatrischen Assessments: Vergleich der Selbstausfüllerversion mit der Interviewversion

In an earlier study we have shown good internal consistency and test-retest-reliability of a newly developed German-language instrument in the interviewer-administered version. The aim of this study was to test the reliability of a self-administered version compared to the original interviewer-administered version of our newly developed German-language instrument. We recruited a group of 50 over 75-year-old community-dwelling persons in Hamburg, Germany (N = 25) and Berne, Switzerland (N = 25). The questionnaire contains items on: self-perceived health, chronic conditions, basic and instrumental activities of daily living, urinary incontinence, nutrition, recent falls, pain, the social support/network and preventive-care measures. In addition, the Functional Status Questionnaire, the Physical Activity Scale for the Elderly, the Geriatric Oral Health Assessment Index, the Visual Function Questionnaire, the Hearing Handicap Inventory for the Elderly and the Geriatric Depression Scale were administered. Cohens Kappa (self-administered version compared to the interviewer-administered version) was good to excellent (0.69-1.0) with only three exceptions (physical activity kappa = 0.49, basic activities kappa = 0.54 and oral health kappa = 0.54). For the domains activities of daily living, oral health, visual function and depression the self-administered version detected significantly more problems than the interview. In the future the self-administered version of this assessment instrument can be used for various purposes, e.g. (annual) preventive geriatric assessment for outpatients and other community-dwelling persons and epidemiological studies in older persons.

Test-Retest-Reliabilität eines deutschsprachigen multidimensionalen Assessmentinstruments bei älteren Personen

Zusammenfassung Viele geriatrische Assessment-Instrumente sind nur in ihrer englischen Version untersucht worden. Wir überprüften die Test-Retest-Reliabilität und die interne Konsistenz eines neu entwickelten multidimensionalen Fragebogens für geriatrisches Assessment.    Bei einer Gruppe von 100 über 75jährigen zu Hause lebenden Personen (Durchschnittsalter 83,0 Jahre, 81% Frauen) in Hamburg (n=26), Ulm (n=51) und Bern (n=23) wurden im Abstand von 1 Woche zwei identische Interviews mit einem multidimensionalen Fragebogen von jeweils der gleichen geschulten Interviewerin durchgeführt.    Der Fragebogen beinhaltete Fragen zum allgemeinen Gesundheitszustand, zu chronischen Krankheiten, zu den Grundaktivitäten (BADL), zu instrumentellen Aktivitäten (IADL), zur Ernährung, zur Urininkontinenz, zu Schmerzen, zur sozialen Situation und zu Vorsorgeuntersuchungen. Zusätzlich beinhaltete er den Fragebogen zu den Funktionen im Alltag (FSQ), die Körperliche Aktivitätsskala für ältere Personen (PASE), Fragebögen zur oralen Gesundheit (GOHAI), zur Sehfunktion (VFQ-25), zur Gehörfunktion (HHIE-S), zu Stürzen und die Geriatrische Depressionsskala (GDS).    Die Test-Retest-Reliabilität (Cohen’s Kappa) war für alle Bereiche gut bis sehr gut (0,64≤κ≤0,89) außer für die Schmerzfragen (κ=0,53), die Fragen nach den Vorsorgeuntersuchungen (κ=0,51) und für eine der Sturzfragen (κ=0,44). Die Werte des Cronbach Alpha (interne Konsistenz) waren für alle Bereiche gut bis sehr gut (0,76≤α≤0,95). Es fanden sich ähnliche Ergebnisse für Personen mit unterschiedlichem Ausbildungsstand und mit unterschiedlichen Scores beim Mini-Mental-Status.    Die Resultate dieser Studie zeigen, dass das neu zusammengefügte multidimensionale Instrument in der deutschen Sprache eine gute Test-Retest-Reliabilität und interne Konsistenz aufweist, und damit zum Beispiel für präventive Beratungen oder für epidemiologische Untersuchungen bei älteren Menschen eingesetzt werden kann.Summary Most geriatric assessment instruments have been developed in the English language. Translated versions might differ in their psychometric properties. We analyzed the test-retest reliability and internal consistency of a German instrument for multidimensional geriatric assessment that was based on a newly developed English version.    A group of 100 over 75-year-old community-dwelling persons (mean age 83.0 years, 81% women) in Hamburg (n=26) and Ulm (n=51), Germany, and Berne (n=23), Switzerland was interviewed twice by the same trained interviewers with a one week interval.     We administered questions on general health, chronic disorders, basic and instrumental activities of daily living, urinary incontinence, nutrition, falls, pain, the social support/network and preventive care measures. In addition, the Functional Status Questionnaire, the Physical Activity Scale for the Elderly, the Geriatric Oral Health Assessment Index, the Visual Function Questionnaire, the Hearing Handicap Inventory for the Elderly and the Geriatric Depression Scale were administered.    Cohen’s kappa was good to excellent (0.64≤κ≤0.89) with only three exceptions (pain questions, κ=0.53; questions on preventive care services, κ=0.51; and one of the questions on recent falls, κ=0.44). Cronbach alpha (internal consistency) was good to excellent for all domains (0.76≤α≤0.95).    The study results confirm good test-retest reliability of the German version of this multidimensional geriatric assessment instrument. Adapted versions of this instrument can be used for different purposes, e.g., preventive home visits, outpatient geriatric assessments or epidemiological studies in older persons.
