Health care for older adults in Europe: how has it evolved and what are the challenges?

Geriatric medicine has evolved to an accepted specialty in 23 European countries. Despite much heterogeneity of postgraduate geriatric curricula, European societies have succeeded in defining a common core curriculum with a list of minimum training requirements for obtaining the specialty title of geriatric medicine. Geriatricians play a leading role in finding solutions for the challenges of health care of multimorbid older patients. One of these challenges is the demographic shift with the number of adults aged 80 years and older in Europe expected to double by 2050. Although geriatric units will play a role in the care of frail older patients, new care models are needed to integrate the comprehensive geriatric assessment approach for the care of the vast majority of older patients admitted to non-geriatric hospital units. Over the last few years, co-management approaches have been developed to address this gap. Innovative models are also in progress for ambulatory care, prevention and health promotion programs, and long-term care. Efforts to implement geriatric learning objectives in undergraduate training, and the generation of practice guidelines for geriatric syndromes may help to improve the quality of care for older patients

Reducing hip fracture risk with risedronate in elderly women with established osteoporosis

Tahir Masud1, Michael McClung2, Piet Geusens31Nottingham University Hospitals NHS Trust, Nottingham, UK; 2Oregon Osteoporosis Center, Portland, Oregon, USA; 3Department of Internal Medicine, Subdivision of Rheumatology, Maastricht University Medical Center, BelgiumBackground: There is limited evidence to support the efficacy of current pharmaceutical agents in reducing the risk of hip fracture in older postmenopausal women with established osteoporosis.Objective: To clarify the efficacy of risedronate in reducing the risk of hip fracture in elderly postmenopausal women aged ≥70 years with established osteoporosis, i.e., those with bone mineral density-defined osteoporosis and a prevalent vertebral fracture.Methods: Post hoc analysis of the Hip Intervention Program (HIP) study, a randomized controlled trial comparing risedronate with placebo for reducing the risk of hip fracture in elderly women. Women aged 70 to 100 years with established osteoporosis (baseline femoral neck T-score ≤ −2.5 and ≥ 1 prior vertebral fracture) were included. The main outcome measure was 3-year hip fracture incidence in the risedronate and placebo groups.Results: A total of 1656 women met the inclusion criteria. After 3 years, hip fracture had occurred in 3.8% of risedronate-treated patients and 7.4% of placebo-treated patients (relative risk 0.54; 95% confidence interval 0.32–0.91; P = 0.019).Conclusion: Risedronate significantly reduced the risk of hip fracture in women aged up to 100 years with established osteoporosis.Keywords: osteoporosis, postmenopausal, hip fracture, risedronat

Vibration therapy

Whole body vibration training (WBV) involves standing or exercising on a vibrating platform. WBV has been suggested to benefit bone strength and neuromuscular function, so could potentially reduce risk of fracture by preventing falls as well as increasing bone strength. Whilst some potential has been demonstrated, findings have been mixed, perhaps in part due to the variation in vibration interventions that have been delivered and the groups of participants studied

Does bone mineral density improve the predictive accuracy of fracture risk assessment?: a prospective cohort study in Northern Denmark

Objective: To evaluate the added predictive accuracy of bone mineral density (BMD) to fracture risk assessment.Design Prospective cohort study using data between 01 January 2010 and 31 December 2012. Setting: North Denmark Osteoporosis Clinic of referred patients presenting with at least one fracture risk factor to the referring doctor.Participants Patients aged 40–90 years; had BMD T-score recorded at the hip and not taking osteoporotic preventing drugs for more than 1 year prior to baseline. Main outcome measures: Incident diagnoses of osteoporotic fractures (hip, spine, forearm, humerus and pelvis) were identified using the National Patient Registry of Denmark during 01 January 2012–01 January 2014. Cox regression was used to develop a fracture model based on predictors in the Fracture Risk Assessment Tool (FRAX®), with and without, binary and continuous BMD. Change in Harrell’s C-Index and Reclassification tables were used to describe the added statistical value of BMD. Results: Adjusting for predictors included in FRAX®, patients with osteoporosis (T-score ≤−2.5) had 75% higher hazard of a fracture compared with patients with higher BMD (HR: 1.75 (95% CI 1.28 to 2.38)). Forty per cent lower hazard was found per unit increase in continuous BMD T-score (HR: 0.60 (95% CI 0.52 to 0.69)).Accuracy improved marginally, and Harrell’s C-Index increased by 1.2% when adding continuous BMD (0.76 to 0.77). Reclassification tables showed continuous BMD shifted 529 patients into different risk categories; 292 of these were reclassified correctly (57%; 95% CI 55% to 64%). Adding binary BMD however no improvement: Harrell’s C-Index decreased by 0.6%. Conclusions: Continuous BMD marginally improves fracture risk assessment. Importantly, this was only found when using continuous BMD measurement for osteoporosis. It is suggested that future focus should be on evaluation of this risk factor using routinely collected data and on the development of more clinically relevant methodology to assess the added value of a new risk factor

Novel use of the Nintendo Wii board as a measure of reaction time: a study of reproducibility in older and younger adults

BACKGROUND: Reaction time (RT) has been associated with falls in older adults, but is not routinely tested in clinical practice. A simple, portable, inexpensive and reliable method for measuring RT is desirable for clinical settings. We therefore developed a custom software, which utilizes the portable and low-cost standard Nintendo Wii board (NWB) to record RT. The aims in the study were to (1) explore if the test could differentiate old and young adults, and (2) to study learning effects between test-sessions, and (3) to examine reproducibility. METHODS: A young (n = 25, age 20–35 years, mean BMI of 22.6) and an old (n = 25, age ≥65 years, mean BMI of 26.3) study-population were enrolled in this within- and between-day reproducibility study. A standard NWB was used along with the custom software to obtain RT from participants in milliseconds. A mixed effect model was initially used to explore systematic differences associated with age, and test-session. Reproducibility was then expressed by Intraclass Correlation Coefficients (ICC), Coefficient of Variance (CV), and Typical Error (TE). RESULTS: The RT tests was able to differentiate the old group from the young group in both the upper extremity test (p < 0.001; −170.7 ms (95%CI −209.4;-132.0)) and the lower extremity test (p < 0.001; −224.3 ms (95%CI −274.6;-173.9)). Moreover, the mixed effect model showed no significant learning effect between sessions with exception of the lower extremity test between session one and three for the young group (−35,5 ms; 4.6 %; p = 0.02). A good within- and between-day reproducibility (ICC: 0.76-0.87; CV: 8.5-12.9; TE: 45.7-95.1 ms) was achieved for both the upper and lower extremity test with the fastest of three trials in both groups. CONCLUSION: A low-cost and portable reaction test utilizing a standard Nintendo wii board showed good reproducibility, no or little systematic learning effects across test-sessions, and could differentiate between young and older adults in both upper and lower extremity tests

Association between number of medications and mortality in geriatric inpatients : a Danish nationwide register-based cohort study

Purpose: To explore the association between the number of medications and mortality in geriatric inpatients taking activities of daily living and comorbidities into account. Methods: A nationwide population-based cohort study was performed including all patients aged C65 years admitted to geriatric departments in Denmark during 2005-2014. The outcome of interest was mortality. Activities of daily living using Barthel-Index (BI) were measured at admission. National health registers were used to link data on an individual level extracting data on medications, and hospital diseases. Patients were followed to the end of study (31.12.2015), death, or emigration, which ever occurred first. Kaplan-Meier survival curves were used to estimate crude survival proportions. Univariable and multivariable analyses were performed using Cox regression. The multivariable analysis adjusted for age, marital status, period of hospital admission, BMI, and BI (model 1), and further adding either number of diseases (model 2) or Charlson comorbidity index (model 3). Results: We included 74603 patients (62.8% women), with a median age of 83 (interquartile range [IQR] 77-88) years. Patients used a median of 6 (IQR 4-9) medications. Increasing number of medications was associated with increased overall, 30-days, and 1-year mortality in all 3 multivariable models for both men and women. For each extra medication the mortality increased by 3% in women and 4% in men in the fully adjusted model. Conclusion: Increasing number of medications was associated with mortality in this nationwide cohort of geriatric inpatients. Our findings highlight the importance of polypharmacy in older patients with comorbidities

Induced frailty and acute sarcopenia are overlapping consequences of hospitalisation in older adults

OBJECTIVES: To determine the effects of hospitalisation upon frailty and sarcopenia. METHODS: Prospective cohort study at single UK hospital including adults ≥70 years-old admitted for elective colorectal surgery, emergency abdominal surgery, or acute infections. Serial assessments for frailty (Fried, Frailty Index, Clinical Frailty Scale [CFS]), and sarcopenia (handgrip strength, ultrasound quadriceps and/or bioelectrical impedance analysis, and gait speed and/or Short Physical Performance Battery) were conducted at baseline, 7 days post-admission/post-operatively, and 13 weeks post-admission/post-operatively. RESULTS: Eighty participants were included (mean age 79.2, 38.8% females). Frailty prevalence by all criteria at baseline was higher among medical compared to surgical participants. Median and estimated marginal CFS values and Fried frailty prevalence increased after 7 days, with rates returning towards baseline at 13 weeks. Sarcopenia incidence amongst those who did not have sarcopenia at baseline was 20.0%. However, some participants demonstrated improvements in sarcopenia status, and overall sarcopenia prevalence did not change. There was significant overlap between diagnoses with 37.3% meeting criteria for all four diagnoses at 7 days. CONCLUSIONS: Induced frailty and acute sarcopenia are overlapping conditions affecting older adults during hospitalisation. Rates of frailty returned towards baseline at 13 weeks, suggesting that induced frailty is reversible
