Abstract
Importance Falls are reported by more than 14 million US adults aged 65 years or older annually and can result in substantial morbidity, mortality, and health care expenditures. Observations Falls result from age-related physiologic changes compounded by multiple intrinsic and extrinsic risk factors. Major modifiable risk factors among community-dwelling older adults include gait and balance disorders, orthostatic hypotension, sensory impairment, medications, and environmental hazards. Guidelines recommend that individuals who report a fall in the prior year, have concerns about falling, or have gait speed less than 0.8 to 1 m/s should receive fall prevention interventions. In a meta-analysis of 59 randomized clinical trials (RCTs) in average-risk to high-risk populations, exercise interventions to reduce falls were associated with 655 falls per 1000 patient-years in intervention groups vs 850 falls per 1000 patient-years in nonexercise control groups (rate ratio [RR] for falls, 0.77; 95% CI, 0.71-0.83; risk ratio for number of people who fall, 0.85; 95% CI, 0.81-0.89; risk difference, 7.2%; 95% CI, 5.2%-9.1%), with most trials assessing balance and functional exercises. In a meta-analysis of 43 RCTs of interventions that systematically assessed and addressed multiple risk factors among individuals at high risk, multifactorial interventions were associated with 1784 falls per 1000 patient-years in intervention groups vs 2317 falls per 1000 patient-years in control groups (RR, 0.77; 95% CI, 0.67-0.87) without a significant difference in the number of individuals who fell. Other interventions associated with decreased falls in meta-analysis of RCTs and quasi-randomized trials include surgery to remove cataracts (8 studies with 1834 patients; risk ratio [RR], 0.68; 95% CI, 0.48-0.96), multicomponent podiatry interventions (3 studies with 1358 patients; RR, 0.77; 95% CI, 0.61-0.99), and environmental modifications for individuals at high risk (12 studies with 5293 patients; RR, 0.74; 95% CI, 0.61-0.91). Meta-analysis of RCTs of programs to stop medications associated with falls have not found a significant reduction, although deprescribing is a component of many successful multifactorial interventions. Conclusions and Relevance More than 25% of older adults fall each year, and falls are the leading cause of injury-related death in persons aged 65 years or older. Functional exercises to improve leg strength and balance are recommended for fall prevention in average-risk to high-risk populations. Multifactorial risk reduction based on a systematic clinical assessment for modifiable risk factors may reduce fall rates among those at high risk.

Central nervous system medication use around hospitalization. J Am Geriatr Soc 2024. [PMID: 38600620 DOI: 10.1111/jgs.18915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 03/07/2024] [Accepted: 03/15/2024] [Indexed: 04/12/2024]
Abstract
BACKGROUND Central nervous system (CNS) medication use is common among older adults, yet the impact of hospitalizations on use remains unclear. This study details CNS medication use, discontinuations, and user profiles during hospitalization periods. METHODS Retrospective cohort study using electronic health records on patients ≥65 years, from three hospitals (2018-2020), and prescribed a CNS medication around hospitalization (90 days prior to 90 days after). Latent class transitions analysis (LCTA) examined profiles of CNS medication class users across four time points (90 days prior, admission, discharge, 90 days after hospitalization). RESULTS Among 4666 patients (mean age 74.3 ± 9.3 years; 63% female; 70% White; mean length of stay 4.6 ± 5.6 days (median 3.0 [2.0, 6.0]), the most commonly prescribed CNS medications were antidepressants (56%) and opioids (49%). Overall, 74% (n = 3446) of patients were persistent users of a CNS medication across all four time points; 7% (n = 388) had discontinuations during hospitalization, but of these, 64% (216/388) had new starts or restarts within 90 days after hospitalization. LCTA identified three profile groups: (1) low CNS medication users, 54%-60% of patients; (2) mental health medication users, 30%-36%; and (3) acute/chronic pain medication users, 9%-10%. Probability of staying in same group across the four time points was high (0.88-1.00). Transitioning to the low CNS medication use group was highest from admission to discharge (probability of 9% for pain medication users, 5% for mental health medication users). Female gender increased (OR 2.4, 95% CI 1.3-4.3), while chronic kidney disease lowered (OR 0.5, 0.2-0.9) the odds of transitioning to the low CNS medication use profile between admission and discharge. CONCLUSIONS CNS medication use stays consistent around hospitalization, with discontinuation more likely between admission and discharge, especially among pain medication users. Further research on patient outcomes is needed to understand the benefits and harms of hospital deprescribing, particularly for medications requiring gradual tapering.

Improving shared decision-making for osteoporosis pharmacologic therapy in nursing homes: a qualitative analysis. Arch Osteoporos 2022; 17:11. [PMID: 34981246 PMCID: PMC9479090 DOI: 10.1007/s11657-021-01050-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 12/16/2021] [Indexed: 02/03/2023]
Abstract
Decisions on whether to use pharmacologic osteoporosis therapy in skilled nursing facility residents are complex and require shared decision-making. Residents, proxies, and staff desire individualized fracture risk estimates that consider advanced age, dementia, and mobility. They want options for reducing administration burden, monitoring instructions, and periodic reassessment of risk vs. benefit. PURPOSE Decisions about pharmacologic osteoporosis treatment in nursing home (NH) residents with advanced age and multimorbidity are complex and should occur using shared decision-making. Our objective was to identify processes and tools to improve shared decision-making about pharmacologic osteoporosis treatment in NHs. METHODS Qualitative analysis of data collected in three NHs from residents at high fracture risk, their proxies, nursing assistants, nurses, and one nurse practitioner (n = 28). Interviews explored participants' stories, attitudes, and experiences with oral osteoporosis medication management. Framework analysis was used to identify barriers to shared decision-making regarding osteoporosis treatment in this setting. RESULTS Participants wanted individualized fracture risk estimates that consider immobility, advanced age, and comorbid dementia. Residents and proxies expected nursing staff to be involved in the decision-making; nursing staff wished to be informed on the relative risks vs. benefits of medications and given monitoring instructions. Two important competing demands to address during the shared decision-making process were burdensome administration requirements and polypharmacy. Participants wanted to reassess pharmacologic treatment appropriateness over time as clinical status or goals of care change. CONCLUSIONS Shared decision-making using strategies and tools identified in this analysis may move osteoporosis pharmacologic treatment in NHs and for other older adults with multimorbidity from inappropriate inertia to appropriate prescribing or appropriate inaction.

Strengthening Resident, Proxy, and Staff Engagement in Injury Prevention in Skilled Nursing Facilities. THE GERONTOLOGIST 2021; 62:1112-1123. [PMID: 34971374 PMCID: PMC9451018 DOI: 10.1093/geront/gnab193] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Engaging residents, their proxies, and skilled nursing facility (SNF) staff through effective communication has potential for improving fall-related injury prevention. The purpose of this study was to understand how multiple stakeholders develop and communicate fall-related injury prevention plans to enhance sustained implementation. RESEARCH DESIGN AND METHODS Descriptive qualitative study using framework analysis applied to open-ended semistructured interviews (n = 28) regarding experiences of communication regarding fall-related injury prevention, guided by the Patient and Family Engaged Care framework. Participants included residents at high risk of injury and their proxies, nursing assistants, nurses, and a nurse practitioner from 3 SNFs in the Eastern United States (Massachusetts and North Carolina). RESULTS Interdisciplinary teams were viewed as essential for injury prevention. However, the roles of the interdisciplinary team members were sometimes unclear. Communication structures were often hierarchical, which reduced engagement of nursing assistants and frustrated proxies. Practices that enhanced engagement included knowing the residents, active listening skills, and use of strategies for respecting autonomy. Engagement was inhibited by time constraints, lack of proactive communication among staff, and by challenges eliciting the perspectives of residents with dementia. Resident barriers included desire for autonomy, strong preferences, and language differences. DISCUSSION AND IMPLICATIONS Strengthening team meeting processes and cultivating open communication and collaboration could facilitate staff, resident, and proxy engagement in injury prevention planning and implementation. Skill building and targeting resources to improve communication can address barriers related to staff practices, resident characteristics, and time constraints.

Protocol for the models of primary osteoporosis screening in men (MOPS) cluster randomized trial. Contemp Clin Trials 2021; 112:106634. [PMID: 34844000 DOI: 10.1016/j.cct.2021.106634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 11/15/2021] [Accepted: 11/22/2021] [Indexed: 11/25/2022]
Abstract
Current guidelines recommend primary osteoporosis screening for at-risk men to reduce the morbidity, mortality, and cost associated with osteoporotic fractures. However, analyses in a national Veterans Health Administration cohort of over 4,000,000 men demonstrated that primary osteoporosis screening as it is currently operationalized does not benefit most older Veterans due to inefficient targeting and low subsequent treatment and adherence rates. The overall objective of this study is to determine whether a new model of primary osteoporosis screening reduces fracture risk compared to usual care. We are conducting a pragmatic group randomized trial of 38 primary care teams assigned to usual care or a Bone Health Service (BHS) screening model in which screening and adherence activities are managed by a centralized expert team. The study will: 1) compare the impact of the BHS model on patient-level outcomes strongly associated with fracture rates (eligible proportion screened, proportion meeting treatment criteria who receive osteoporosis medications, medication adherence, and femoral neck bone mineral density); 2) quantify the impact on provider and facility-level outcomes including change in DXA volume, change in metabolic bone disease clinic volume, and PACT provider time and satisfaction; and 3) estimate the impact on health system and policy outcomes using Markov models of screening program cost per quality adjusted life year based from health system and societal perspectives.

Towards "mobility is medicine": Socioecological factors and hospital mobility in older adults. J Am Geriatr Soc 2021; 69:1846-1855. [PMID: 33755991 DOI: 10.1111/jgs.17109] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 02/11/2021] [Accepted: 02/19/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Understanding the factors that influence hospital mobility, especially in the context of a heightened focus on falls prevention, is needed to improve care. OBJECTIVE This qualitative study uses a socioecological framework to explore factors that influence hospital mobility in older adults. DESIGN Qualitative research PARTICIPANTS: Semi-structured interviews and focus groups were conducted with medically-ill hospitalized older adults (n = 19) and providers (hospitalists, nurses, and physical and occupational therapists (n = 48) at two hospitals associated with an academic health system. APPROACH Interview and focus group guides included questions on perceived need for mobility, communication about mobility, hospital mobility culture, and awareness of patients' walking activity. Data were analyzed thematically and mapped onto the constructs of the socioecological model. KEY RESULTS A consistent theme among patients and providers was that "mobility is medicine." Categories of factors reported to influence hospital walking activity included intrapersonal factors (patients' health status, fear of falls), interpersonal factors (patient-provider communication about mobility), organizational factors (clarity about provider roles and responsibilities, knowledge of safe patient handling, reliance on physical therapy for mobility), and environmental factors (falls as a never event, patient geographical locations on hospital units). Several of these factors were identified as potentially modifiable targets for intervention. Patients and providers offered recommendations for improving awareness of patient's ambulatory activity, assigning roles and responsibility for mobility, and enhancing education and communication between patients and providers across disciplines. CONCLUSION Patients and providers identified salient factors for future early mobility initiatives targeting hospitalized older adults. Consideration of these factors across all stages of intervention development and implementation will enhance impact and sustainability.

Machine Learning Algorithms to Predict Mortality and Allocate Palliative Care for Older Patients With Hip Fracture. J Am Med Dir Assoc 2021; 22:291-296. [PMID: 33132014 PMCID: PMC7867606 DOI: 10.1016/j.jamda.2020.09.025] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 09/18/2020] [Accepted: 09/21/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVES To evaluate a machine learning model designed to predict mortality for Medicare beneficiaries aged >65 years treated for hip fracture in Inpatient Rehabilitation Facilities (IRFs). DESIGN Retrospective design/cohort analysis of Centers for Medicare & Medicaid Services Inpatient Rehabilitation Facility-Patient Assessment Instrument data. SETTING AND PARTICIPANTS A total of 17,140 persons admitted to Medicare-certified IRFs in 2015 following hospitalization for hip fracture. MEASURES Patient characteristics include sociodemographic (age, gender, race, and social support) and clinical factors (functional status at admission, chronic conditions) and IRF length of stay. Outcomes were 30-day and 1-year all-cause mortality. We trained and evaluated 2 classification models, logistic regression and a multilayer perceptron (MLP), to predict the probability of 30-day and 1-year mortality and evaluated the calibration, discrimination, and precision of the models. RESULTS For 30-day mortality, MLP performed well [acc = 0.74, area under the receiver operating characteristic curve (AUROC) = 0.76, avg prec = 0.10, slope = 1.14] as did logistic regression (acc = 0.78, AUROC = 0.76, avg prec = 0.09, slope = 1.20). For 1-year mortality, the performances were similar for both MLP (acc = 0.68, AUROC = 0.75, avg prec = 0.32, slope = 0.96) and logistic regression (acc = 0.68, AUROC = 0.75, avg prec = 0.32, slope = 0.95). CONCLUSION AND IMPLICATIONS A scoring system based on logistic regression may be more feasible to run in current electronic medical records. But MLP models may reduce cognitive burden and increase ability to calibrate to local data, yielding clinical specificity in mortality prediction so that palliative care resources may be allocated more effectively.

Cost trajectories as a measure of functional resilience after hospitalization in older adults. Aging Clin Exp Res 2020; 32:2595-2601.

Abstract
BACKGROUND Administrative data sets lack functional measures. AIM We examined whether trajectories of cost can be used as a marker of functional recovery after hospitalization. METHODS Secondary analysis of the National Health and Aging Trends Study merged with Centers for Medicare and Medicaid Services data. Community-dwelling participants with a first hospitalization occurring after any annual survey were included (N = 937). Monthly total cost trajectories were constructed for the 3 months before and 3 months following hospitalization. Growth mixture models identified groups of patients with similar trajectories. The association of cost classes with five functional outcomes was examined using multivariate models, controlling for pre-hospitalization function and lead time. RESULTS Four cost trajectory classes describing common recovery patterns were identified-persistently high, persistently moderate, low-spike-recover, and low variable. Cost class membership was significantly associated with change in Activities of Daily Living (ADL), instrumental ADL, Short Physical Performance Battery, and grip strength (p < 0.005), but not gait speed (p = 0.08). The proportion of patients who maintained or improved SPPB score was 46.8% in the persistently high, 49.2% in the persistently moderate, 52.7% in the low-spike-recover, and 57.2% in the low-variable groups. In models adjusted for known predictors of functional outcome, the magnitude and direction of association was maintained but significance was lost, indicating that cost trajectories' mirror is mediated by predictors of recovery not available in administrative data. CONCLUSION Cost trajectories and total costs are associated with functional recovery following hospitalization in older adults. Cost may be useful as a measure of recovery in administrative data.

Abstract
PURPOSE Patient priorities for quality of life change with age. We conducted a qualitative study to identify quality of life themes of importance to older adults receiving dialysis and the extent to which these are represented in existing quality of life instruments. METHODS We conducted semi-structured interviews with 12 adults aged ≥ 75 years receiving hemodialysis to elicit participant perspectives on what matters most to them in life. We used framework analysis methodology to process interview transcripts (coding, charting, and mapping), identify major themes, and compare these themes by participant frailty status. We examined for representation of our study's subthemes in the Kidney Disease Quality of Life (KDQOL-36) and the World Health Organization Quality of Life for Older Adults (WHOQOL-OLD) instruments. RESULTS Among the 12 participants, average age was 81 (4.2) years, 7 African-American, 6 women, and 6 met frailty criteria. We identified two major quality of life themes: (1) having physical well-being (subthemes: being able to do things independently, having symptom control, maintaining physical health, and being alive) and (2) having social support (subthemes: having practical social support, emotional social support, and socialization). Perspectives on the subthemes often varied by frailty status. For example, being alive meant surviving from day-to-day for frail participants, but included a desire for new life experiences for non-frail participants. The majority of the subthemes did not correspond with domains in the KDQOL-36 and WHOQOL-OLD instruments. CONCLUSION Novel instruments are likely needed to elicit the dominant themes of having physical well-being and having social support identified by older adults receiving dialysis.

Determinants of Maintenance and Recovery of Function in a Representative Older Community-Resident Biracial Sample. J Am Med Dir Assoc 2020; 21:1141-1147.e1. [PMID: 32037299 DOI: 10.1016/j.jamda.2019.12.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 12/19/2019] [Accepted: 12/20/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVES Focus on decline in performance of activities of daily living (ADL) has not been matched by studies of recovery of function. Advised by a broad conceptual model of physical resilience, we ascertain characteristics that identify (1) maintenance, (2) decline, and (3) recovery of personal self-maintenance activities over six years in an older, community representative, African American and white sample. DESIGN Longitudinal study, analyses included descriptive statistics and repeated measures proportional hazards. SETTING/PARTICIPANTS Community-representative participants of the Duke Established Populations for Epidemiologic Studies of the Elderly (EPESE), unimpaired at baseline (n = 3187; 46% white, 54% African American; 64% female, 36% male), followed annually for up to 6 years. MEASURES Data included information on basic activities of daily living (BADL), demographic characteristics, health status, social services provided and received, household size, neighborhood safety, and survival status. RESULTS Over 6 years, ∼75% remained unimpaired, of whom 30% were unimpaired when they dropped out or died. Of ∼25% who became impaired, just under half recovered. Controlled analyses indicated that those who became impaired were in poorer health, younger, and more likely to be African American. Characteristics of recovery included younger age, not hospitalized in the previous year, and larger household size. CONCLUSIONS/IMPLICATIONS Maintenance of health status facilitated continued unimpaired BADL. While decline was associated with poorer health, younger age, and being African American, recovery was also associated with younger age, together with larger household size, and no further deterioration in health as measured here. Maintenance of good health is preferred, but following decline in functioning, increased effort to improve health and avoid further decline, which takes into account not only physical but also personal social conditions, is needed.

Abstract
BACKGROUND Hospital-acquired disability (HAD) is common and often related to low physical activity while in the hospital. OBJECTIVE To examine whether wearable hospital activity trackers can be used to predict HAD. DESIGN A prospective observational study between January 2016 and March 2017. SETTING An academic medical center. PARTICIPANTS Community-dwelling older adults, aged 60 years or older, enrolled within 24 hours of admission to general medicine (n = 46). MAIN MEASURES Primary outcome was HAD, defined as having one or more new activity of daily living deficits, decline of four or greater on the Late-Life Function and Disability Instrument (calculated between baseline and discharge), or discharge to a skilled nursing facility. Hospital activity (mean active time, mean sedentary time, and mean step counts per day) was measured using ankle-mounted accelerometers. The association of the literature-based threshold of 900 steps/day with HAD was also evaluated. RESULTS Mean age was 73.2 years (SD = 9.5 years), 48% were male, and 76% were white. Median length of stay was 4 days (interquartile range [IQR] = 2.0-6.0 days); 61% (n = 28) reported being able to walk without assistance of another person or walking aid at baseline. Median daily activity time and step counts were 1.1 h/d (IQR = 0.7-1.7 h/d) and 1455.7 steps/day (IQR = 908.5-2643 steps/day), respectively. Those with HAD (41%; n = 19) had lower activity time (0.8 vs 1.4 h/d; P = .04) and fewer step counts (1186 vs 1808 steps/day; P = .04), but no difference in sedentary time, compared to those without HAD. The 900 steps/day threshold had poor sensitivity (40%) and high specificity (85%) for detecting HAD. CONCLUSIONS Low hospital physical activity, as measured by wearable accelerometers, is associated with HAD. Clinicians can utilize wearable technology data to refer patients to physical/occupational therapy services or other mobility interventions, like walking programs. J Am Geriatr Soc 68:261-265, 2020.

Abstract
Rationale & Objective Timely recognition of functional decline in older adults receiving dialysis will allow clinicians to pursue interventions to prevent further disability and/or lead patient-centered goals of care discussions. Annual change in the 12-Item Short Form Health Survey (SF-12) physical component score (PCS) could identify patients with functional decline. Our objectives were to assess SF-12 PCS change over a year, risk factors associated with SF-12 PCS change, and the association of SF-12 PCS change with mortality in a survivor cohort of older adults receiving dialysis. Study Design Retrospective study. Setting & Participants 1,371 adults 65 years or older receiving hemodialysis for 6 or more months who completed SF-12 PCSs 300 or more days apart from 2012 to 2013. Exposures Serum albumin level; hemodialysis access type; SF-12 PCS change (for mortality analyses). Outcomes SF-12 PCS change and mortality. Analytical Approach Multivariable-adjusted linear regression model; Cox proportional hazards model. Results We excluded 24% (n = 801) of our cohort for death before the second SF-12 PCS. Among the 1,371 with sufficient SF-12 PCS data, mean age was 79.9 ± 4.5 years. Average SF-12 PCS change in 1 year was minimal (−0.9 ± 9.6), but 39.3% (n = 539) and 32.2% (n = 442) had clinically relevant SF-12 PCS decline and improvement, respectively. Albumin level and access type were not statistically associated with SF-12 PCS change. SF-12 PCS change was not associated with mortality (adjusted HR, 0.98; 95% CI, 0.96-1.00). Limitations 2 time points to assess SF-12 PCS change; covariate assessment only at baseline; survivor bias. Conclusions In this cohort of older adults receiving hemodialysis, nearly one-fourth died, while among survivors, it was more common for SF-12 PCS to decline than improve in a year. Annual SF-12 PCS change was not associated with traditional risk factors for functional impairment or mortality risk. Additional research is needed to identify appropriate measures and frequency of assessment for functional decline.

Abstract
OBJECTIVE To determine the association between dual-energy x-ray absorptiometry (DXA) testing for osteoporosis and subsequent fractures in US male veterans without a previous fracture. PATIENTS AND METHODS This is a propensity score-matched observational study using Centers for Medicare and Medicaid Services and Veterans Affairs (VA) data from January 1, 2000, through December 31, 2010, with a mean follow-up time of 4.7 years (range, 0-10 years). Men receiving VA primary care aged 65 to 99 years without a previous fracture (N=2,539,812) were included. Men undergoing DXA testing were propensity score matched with untested controls in a 1:3 ratio, indicating the probability of DXA testing within the next year. Time to first clinical fracture was the primary outcome. Comorbidities, demographic characteristics, medications, DXA results, and osteoporosis treatment were defined using administrative data and natural language processing. A landmark analysis contingent on surviving to 12 months after screening was completed, accounting for competing risk of mortality. RESULTS During follow-up of 153,311 men tested by DXA and 390,158 controls, 56,083 (10.3%) had sustained a fracture and 111,774 (20.6%) died. Overall, DXA testing was not associated with a decrease in fractures; conclusions are limited by unmeasured confounders and low medication initiation and adherence in those meeting treatment thresholds (12% of follow-up time). In contrast, DXA testing in prespecified subgroups was associated with a lower risk of fracture in comparison to the overall population who underwent DXA testing: androgen deprivation therapy (hazard ratio [HR], 0.77; 95% CI, 0.66-0.89), glucocorticoids (HR, 0.77; 95% CI, 0.72-0.84), age 80 years and older (HR, 0.85; 0.81-0.90), 1 or more VA guideline risk factors (HR, 0.91; 95% CI, 0.87-0.95), and high Fracture Risk Assessment Tool using body mass index score (HR, 0.90; 95% CI, 0.86-0.95). CONCLUSION Current VA DXA testing practices are ineffective overall; interventions to improve treatment adherence are needed. Targeted DXA testing in higher-risk men was associated with a lower fracture risk.

Automated versus Manual Data Extraction of the Padua Prediction Score for Venous Thromboembolism Risk in Hospitalized Older Adults. Appl Clin Inform 2018; 9:743-751. [PMID: 30257260 PMCID: PMC6158031 DOI: 10.1055/s-0038-1670678] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Accepted: 08/09/2018] [Indexed: 10/28/2022] Open
Abstract
OBJECTIVE Venous thromboembolism (VTE) prophylaxis is an important consideration for hospitalized older adults, and the Padua Prediction Score (PPS) is a risk prediction tool used to prioritize patient selection. We developed an automated PPS (APPS) algorithm using electronic health record (EHR) data. This study examines the accuracy of APPS and its individual components versus manual data extraction. METHODS This is a retrospective cohort study of hospitalized general internal medicine patients, aged 70 and over. Fourteen clinical variables were collected to determine their PPS; APPS used EHR data exports from health system databases, and a trained abstractor performed manual chart abstractions. We calculated sensitivity and specificity of the APPS, using manual PPS as the gold standard for classifying risk category (low vs. high). We also examined performance characteristics of the APPS for individual variables. RESULTS PPS was calculated by both methods on 311 individuals. The mean PPS was 3.6 (standard deviation, 1.8) for manual abstraction and 2.8 (1.4) for APPS. In detecting patients at high risk for VTE, the sensitivity and specificity of the APPS algorithm were 46 and 94%, respectively. The sensitivity for APPS was poor (range: 6-34%) for detecting acute conditions (i.e., acute myocardial infarction), moderate (range: 52-74%) for chronic conditions (i.e., heart failure), and excellent (range: 94-98%) for conditions of obesity and restricted mobility. Specificity of the automated extraction method for each PPS variable was > 87%. CONCLUSION APPS as a stand-alone tool was suboptimal for classifying risk of VTE occurrence. The APPS accurately identified high risk patients (true positives), but lower scores were considered indeterminate.

Abstract
OBJECTIVE To document changes in 30-day hospital readmission rates and causes for returning to the hospital for care in THR patients. DESIGN Retrospective cross-sectional descriptive design. SETTING Community-based acute care hospitals. PARTICIPANTS Total sample size (N=142,022) included THR patients (identified as ICD-9-CM procedure code 81.51) in 2009 (n=31,232) and (n=32,863) in 2014. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES 30-Day hospital readmission. RESULTS The overall readmission rate decreased by 1.3% from 2009 to 2014. The decrease in readmission rates varied by groups, with lesser improvements seen in THR patients who were younger, with private insurance, and residing in lower-income and rural communities. Device complications were the leading cause of readmission in THR patients, increasing from 19.8% in 2009 to 23.9% in 2014. CONCLUSIONS There has been little decrease in hospital 30-day readmission rates for US community hospitals between 2009 and 2014. Findings from this brief report indicate patient groups at greater risk for 30-day hospital readmission as well as leading causes for readmission in THR patients which can inform the development of tailored interventions for reduction.

Association of Kidney Disease Quality of Life (KDQOL-36) with mortality and hospitalization in older adults receiving hemodialysis. BMC Nephrol 2018; 19:11. [PMID: 29334904 PMCID: PMC5769495 DOI: 10.1186/s12882-017-0801-5] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2017] [Accepted: 12/18/2017] [Indexed: 11/17/2022] Open
Abstract
Background For older adults receiving dialysis, health-related quality of life is not often considered in prognostication of death or future hospitalizations. To determine if routine health-related quality of life measures may be useful for prognostication, the objective of this study is to determine the extent of association of Kidney Disease Quality of Life (KDQOL-36) subscales with adverse outcomes in older adults receiving dialysis. Methods This is a longitudinal study of 3500 adults aged ≥75 years receiving dialysis in the United States in 2012 and 2013. We used Cox and Fine and Gray models to evaluate the association of KDQOL-36 subscales with risk of death and hospitalization. We adjusted for sociodemographic variables, hemodialysis access type, laboratory values, and Charlson index. Results Three thousand one hundred thirty-two hemodialysis patients completed the KDQOL-36. From KDQOL-36 completion date in 2012, 880 (28.1%) died and 2023 (64.6%) had at least one hospitalization over a median follow-up of 512 and 203 days, respectively. Cohort members with a SF-12 physical component summary (PCS) in the lowest quintile had an increased adjusted risk of death [hazard ratio (HR), 1.55, 95% confidence interval (CI) 1.19–2.03] and hospitalization (HR, 1.29, 95% CI 1.09–1.54) compared with those with scores in the highest quintile. Cohort members with a SF-12 mental component summary in the lowest quintile had an increased risk of hospitalization (HR, 1.39, 95% CI 1.17–1.65) compared with those in the highest quintile. In adjusted analyses, there was no association between the symptoms of kidney disease, effects of kidney disease, and burden of kidney disease subscales with time to death or first hospitalization. Competing risk models showed similar HRs. Conclusions Among the KDQOL-36 subscales, the SF-12 PCS demonstrates the strongest association with both death and future hospitalizations in older adults receiving hemodialysis Further research is needed to assess the value this subscale may add to prognostication.

Abstract
IMPORTANCE New approaches are needed to enhance implementation of complex interventions for geriatric syndromes such as falls. OBJECTIVE To test whether a complexity science-based staff training intervention (CONNECT) promoting high-quality staff interactions improves the impact of an evidence-based falls quality improvement program (FALLS). DESIGN, SETTING, AND PARTICIPANTS Cluster-randomized trial in 24 nursing homes receiving either CONNECT followed by FALLS (intervention), or FALLS alone (control). Nursing home staff in all positions were asked to complete surveys at baseline, 3, 6, and 9 months. Medical records of residents with at least 1 fall in the 6-month pre- and postintervention windows (n = 1794) were abstracted for fall risk reduction measures, falls, and injurious falls. INTERVENTIONS CONNECT taught staff to improve their connections with coworkers, increase information flow, and use cognitive diversity in problem solving. Intervention components included 2 classroom sessions, relationship mapping, and self-monitoring. FALLS provided instruction in the Agency for Healthcare Research and Quality's Falls Management Program. MAIN OUTCOMES AND MEASURES Primary outcomes were (1) mean number of fall risk reduction activities documented within 30 days of falls and (2) median fall rates among residents with at least 1 fall during the study period. In addition, validated scales measured staff communication quality, frequency, timeliness, and safety climate. RESULTS Surveys were completed by 1545 staff members, representing 734 (37%) and 811 (44%) of eligible staff in intervention and control facilities, respectively; 511 (33%) respondents were hands-on care workers. Neither the CONNECT nor the FALLS-only facilities improved the mean count of fall risk reduction activities following FALLS (3.3 [1.6] vs 3.2 [1.5] of 10); furthermore, adjusted median recurrent fall rates did not differ between the groups (4.06 [interquartile range {IQR}, 2.03-8.11] vs 4.06 [IQR, 2.04-8.11] falls/resident/y). A modest improvement in staff communication measures was observed overall (mean, 0.03 [SE, 0.01] points on a 5-point scale; P = .03) and for communication timeliness (mean, 0.8 [SE, 0.03] points on a 5-point scale; P = .02). There was wide variation across facilities in intervention penetration. CONCLUSIONS AND RELEVANCE An intervention targeting gaps in staff communication and coordination did not improve the impact of a falls quality improvement program. New approaches to implementing evidence-based care for complex conditions in the nursing home are urgently needed. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00636675.

Choice of Hemodialysis Access in Older Adults: A Cost-Effectiveness Analysis. Clin J Am Soc Nephrol 2017; 12:947-954.

Abstract
BACKGROUND AND OBJECTIVES Although arteriovenous fistulas have been found to be the most cost-effective form of hemodialysis access, the relative benefits of placing an arteriovenous fistula versus an arteriovenous graft seem to be least certain for older adults and when placed preemptively. However, older adults' life expectancy is heterogeneous, and most patients do not undergo permanent access creation until after dialysis initiation. We evaluated cost-effectiveness of arteriovenous fistula placement after dialysis initiation in older adults as a function of age and life expectancy. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Using a hypothetical cohort of patients on incident hemodialysis with central venous catheters, we constructed Markov models of three treatment options: (1) arteriovenous fistula placement, (2) arteriovenous graft placement, or (3) continued catheter use. Costs, utilities, and transitional probabilities were derived from existing literature. Probabilistic sensitivity analyses were performed by age group (65-69, 70-74, 75-79, 80-84, and 85-89 years old) and quartile of life expectancy. Costs, quality-adjusted life-months, and incremental cost-effectiveness ratios were evaluated for up to 5 years. RESULTS The arteriovenous fistula option was cost effective compared with continued catheter use for all age and life expectancy groups, except for 85-89 year olds in the lowest life expectancy quartile. The arteriovenous fistula option was more cost effective than the arteriovenous graft option for all quartiles of life expectancy among the 65- to 69-year-old age group. For older age groups, differences in cost-effectiveness between the strategies were attenuated, and the arteriovenous fistula option tended to only be cost effective in patients with life expectancy >2 years. For groups for which the arteriovenous fistula option was not cost saving, the cost to gain one quality-adjusted life-month ranged from $2294 to $14,042. CONCLUSIONS Among older adults, the cost-effectiveness of an arteriovenous fistula placed within the first month of dialysis diminishes with increasing age and lower life expectancy and is not the most cost-effective option for those with the most limited life expectancy.

Abstract
OBJECTIVES Little is known about how nursing home staff use resident characteristics to individualize care delivery or whether care is affected by implicit bias. DESIGN Randomized factorial clinical vignette survey. SETTING Sixteen nursing homes in North Carolina. PARTICIPANTS Nursing, rehabilitation, and social services staff (n = 433). MEASUREMENTS Vignettes describing hypothetical residents were generated from a matrix of clinical and demographic characteristics. Resident age, race and gender were suggested by a photo. Participants completed up to four randomly assigned vignettes (n = 1615), rating the likelihood that 12 fall prevention activities would be used for the resident. Fixed and random effects mixed model analysis examined the impact of vignette resident characteristics and staff characteristics on four intervention categories. RESULTS Staff reported a higher likelihood of fall prevention activities in all four categories for residents with a prior fall (0.2-0.5 points higher, 10 point scale, P < 0.05), but other risk factors did not affect scores. There was little evidence of individualization; only dementia increased the reported likelihood of environmental modification (0.3, P < 0.001, 95% CI 0.2-0.5). Individualization did not vary with staff licensure category or clinical experience. Registered nurses consistently reported higher likelihoods of all fall prevention activities than did licensed practical nurses, unlicensed staff and other professional staff (1.0-2.7 points, P < 0.001 to 0.005). There was a small degree of implicit racial bias; staff indicated that environmental modification would be less likely to occur in otherwise identical vignettes including a photo of a black rather than a white resident (-0.2 points, 95% CI -0.3 to -0.1). CONCLUSION Nursing home staff report a standardized approach to fall prevention without individualization. We found a small impact from implicit racial bias that should be further explored.

Abstract
PURPOSE OF THE STUDY Postmenopausal osteoporosis can impact quality-of-life even prefracture. To determine whether osteoporosis should be a greater concern in women Veterans versus non-Veterans, we compared fracture rates and bone mineral density (BMD) for Veterans and non-Veterans using Women's Health Initiative data. DESIGN AND METHODS In this cohort study, participants were women aged 50-79 years. Outcomes were hip, central body, and limb fractures occurring during up to 19 years of follow-up and hip, spine, and whole body BMD collected three times over a 6-year period in a participant subsample. Covariates comprised risk factors for fracture, including fall history and other components of the World Health Organization Fracture Risk Assessment Tool (FRAX). Cox Proportional Hazards models were used to examine fracture rates for Veterans compared with non-Veterans. RESULTS Of 161,808 women, 145,521 self-identified as Veteran (n = 3,719) or non-Veteran (n = 141,802). Baseline FRAX scores showed that Veterans had higher 10-year probabilities for any major fracture (13.3 vs 10.2; p < .01) and hip fracture (4.1 vs 2.2; p < .01) compared with non-Veterans. The age-adjusted rate of hip fracture per 1,000 person-years for Veterans was 3.3 versus 2.4 for non-Veterans (p < .01). After adjustment, the hazards ratio for hip fracture was 1.24 (95% confidence interval 1.03-1.49) for Veterans versus non-Veterans. Hazards ratios at other anatomic sites did not differ by Veteran status. Mean BMD at baseline and at Years 3 and 6 also did not differ by Veteran status at any site. IMPLICATIONS Women Veterans had an increased hip fracture rate not explained by differences in well-recognized fracture risk factors.

Abstract
Older adults with advanced chronic kidney disease (CKD) experience functional impairment that can complicate CKD management. Failure to recognize functional impairment may put these individuals at risk of further functional decline, nursing home placement, and missed opportunities for timely goals-of-care conversations. Routine geriatric assessment could be a useful tool for identifying older adults with CKD who are at risk of functional decline and provide contextual information to guide clinical decision-making. Two innovative programs were implemented in the Veterans Health Administration that incorporate geriatric assessment into a nephrology visit. In one program, a geriatrician embedded in a nephrology clinic used standardized geriatric assessment tools with individuals with CKD aged 70 and older (Comprehensive Geriatric Assessment for CKD) (CGA-4-CKD). In the second program, a nephrology clinic used comprehensive appointments for individuals aged 75 and older to conduct geriatric assessments and CKD care (Renal Silver). Data on 68 veterans who had geriatric assessments through these programs between November 2013 and May 2015 are reported. In CGA-4-CKD, difficulty with one or more activities of daily living (ADLs), history of falls, and cognitive impairment were each found in 27.3% of participants. ADL difficulty was found in 65.7%, falls in 28.6%, and cognitive impairment in 51.6% of participants in Renal Silver. Geriatric assessment guided care processes in 45.4% (n = 15) of veterans in the CGA-4-CKD program and 37.1% (n = 13) of those in Renal Silver. Findings suggest there is a significant burden of functional impairment in older adults with CKD. Knowledge of this impairment is applicable to CKD management.

Abstract
Observational studies are an important source of evidence for evaluating treatment benefits and harms in older adults, but lack of comparability in the outcome risk factors between the treatment groups leads to confounding. Propensity score (PS) analysis is widely used in aging research to reduce confounding. Understanding the assumptions and pitfalls of common PS analysis methods is fundamental to applying and interpreting PS analysis. This review was developed based on a symposium of the American Geriatrics Society Annual Meeting on the use and interpretation of PS analysis in May 2014. PS analysis involves two steps: estimation of PS and estimation of the treatment effect using PS. Typically estimated from a logistic model, PS reflects the probability of receiving a treatment given observed characteristics of an individual. PS can be viewed as a summary score that contains information on multiple confounders and is used in matching, weighting, or stratification to achieve confounder balance between the treatment groups to estimate the treatment effect. Of these methods, matching and weighting generally reduce confounding more effectively than stratification. Although PS is often included as a covariate in the outcome regression model, this is no longer a best practice because of its sensitivity to modeling assumption. None of these methods reduce confounding by unmeasured variables. The rationale, best practices, and caveats in conducting PS analysis are explained in this review using a case study that examined the effective of angiotensin-converting enzyme inhibitors on mortality and hospitalization in older adults with heart failure.

Abstract
BACKGROUND Resilience has been described in the psychosocial literature as the capacity to maintain or regain well-being during or after adversity. Physical resilience is a newer concept that is highly relevant to successful aging. Our objective was to characterize the emerging construct of resilience as it pertains to physical health in older adults, and to identify gaps and opportunities to advance research in this area. METHODS We conducted a systematic review to identify English language papers published through January 2015 that apply the term "resilience" in relation to physical health in older adults. We applied a modified framework analysis to characterize themes in implicit or explicit definitions of physical resilience. RESULTS Of 1,078 abstracts identified, 49 articles met criteria for inclusion. Sixteen were letters or concept papers, and only one was an intervention study. Definitions of physical resilience spanned cellular to whole-person levels, incorporated many outcome measures, and represented three conceptual themes: resilience as a trait, trajectory, or characteristic/capacity. CONCLUSIONS Current biomedical literature lacks consensus on how to define and measure physical resilience. We propose a working definition of physical resilience at the whole person level: a characteristic which determines one's ability to resist or recover from functional decline following health stressor(s). We present a conceptual framework that encompasses the related construct of physiologic reserve. We discuss gaps and opportunities in measurement, interactions across contributors to physical resilience, and points of intervention.

Abstract
This study examined whether chronic kidney disease (CKD) is associated with recurrent falls in older adults in nursing homes (NHs). We used data abstracted over a six month period from 510 NH residents with a history of falls. Thirty-five percent of the NH residents had CKD. In adjusted analyses, the incidence of recurrent falls was similar in those with and without CKD [fall rate ratio (FRR) 1.00, 95% confidence interval (CI) 0.97-1.02]. Orthostatic hypotension (FRR 1.52, 95% CI 1.12-2.05), history of falls during the prior six month period (FRR 1.25, 95% CI 1.05-1.49), cane or walker use (FRR 1.64, 95% CI 1.16-2.33), and ambulatory dysfunction (FRR 1.47, 95% CI 1.23-1.75) were independently associated with increased fall rate. CKD was not an important predictor of falls in this cohort of nursing home residents with prior falls. Instead, traditional fall risk factors were much more strongly associated with recurrent falls.

Abstract
Minimizing post-fracture bone loss is an important aspect of recovery from hip fracture, and determination of factors that affect bone mineral density (BMD) response to treatment after hip fracture may assist in the development of targeted therapeutic interventions. A post hoc analysis of the HORIZON Recurrent Fracture Trial was done to determine the effect of zoledronic acid (ZOL) on total hip (TH) and femoral neck (FN) BMD in subgroups with low-trauma hip fracture. A total of 2127 patients were randomized (1:1) to yearly infusions of ZOL 5 mg (n = 1065) or placebo (n = 1062) within 90 days of operation for low-trauma hip fracture. The 1486 patients with a baseline and at least one post-baseline BMD assessment at TH or FN (ZOL = 745, placebo = 741) were included in the analyses. Percentage change from baseline in TH and FN BMD was assessed at months 12 and 24 and compared across subgroups of hip fracture patients. Percentage change from baseline in TH and FN BMD at months 12 and 24 was greater (p < 0.05) in ZOL-treated patients compared with placebo in most subgroups. Treatment-by-subgroup interactions (p < 0.05) indicated that a greater effect on BMD was observed for TH BMD at month 12 in females, in patients in the lower tertile body mass index at baseline (≤22.6 kg/m(2) ), and in patients with baseline FN BMD T-score of ≤ -2.5; for FN BMD in patients who received ZOL for >6 weeks post-surgery; and for TH and FN BMD in patients with a history of one or more prior fractures. All interactions were limited to the first 12 months after treatment with none observed for the 24-month comparisons. (Clinical trial registration number NCT00046254.)

Abstract
PURPOSE OF THE STUDY To describe key adaptive challenges and leadership behaviors to implement culture change for person-directed care. DESIGN AND METHODS The study design was a qualitative, observational study of nursing home staff perceptions of the implementation of culture change in each of 3 nursing homes. We conducted 7 focus groups of licensed and unlicensed nursing staff, medical care providers, and administrators. Questions explored perceptions of facilitators and barriers to culture change. Using a template organizing style of analysis with immersion/crystallization, themes of barriers and facilitators were coded for adaptive challenges and leadership. RESULTS Six key themes emerged, including relationships, standards and expectations, motivation and vision, workload, respect of personhood, and physical environment. Within each theme, participants identified barriers that were adaptive challenges and facilitators that were examples of adaptive leadership. Commonly identified challenges were how to provide person-directed care in the context of extant rules or policies or how to develop staff motivated to provide person-directed care. IMPLICATIONS Implementing culture change requires the recognition of adaptive challenges for which there are no technical solutions, but which require reframing of norms and expectations, and the development of novel and flexible solutions. Managers and administrators seeking to implement person-directed care will need to consider the role of adaptive leadership to address these adaptive challenges.

Abstract
Osteoporosis and related fractures disproportionately impact patients with advanced age, those with the frailty phenotype, and those with multiple comorbidities. Recent studies report a changing incidence in fracture type among the oldest old throughout the world, a finding not satisfactorily explained by advances in treatment of lifestyle factors. A growing recognition of the importance of muscle and bone interaction is leading to improved understanding of the underlying biochemical pathways linking them and new therapeutic targets. New models of care for frail older populations, particularly after hip fracture, are being developed but have been challenged to identify appropriate outcomes to target. An appreciation for the relationship between age-related comorbidities, fracture risk, and competing mortality risk is essential for practitioners caring for the oldest-old population.

Functional decline in older adults. Am Fam Physician 2013; 88:388-394.

Abstract
Functional disability is common in older adults. It is often episodic and is associated with a high risk of subsequent health decline. The severity of disability is determined by physical impairments caused by underlying medical conditions, and by external factors such as social support, financial support, and the environment. When multiple health conditions are present, they often result in greater disability than expected because the patient's ability to compensate for one problem may be affected by comorbid conditions. Evaluation of functional disability is most effective when the physician determines the course of the disability, associated symptoms, effects on specific activities, and coping mechanisms the patient uses to compensate for the functional problem. Underlying health conditions, impairments, and contextual factors (e.g., finances, social support) should be identified using validated screening tools. Interventions should focus on increasing the patient's capacity to cope with task demands and reducing the demands of the task itself. Interventions for functional decline in older adults are almost always multifactorial because they must address multiple conditions, impairments, and contextual factors.

Abstract
PURPOSE OF THE STUDY The CONNECT intervention is designed to improve staff connections, communication, and use of multiple perspectives for problem solving. This analysis compared staff descriptions of the learning climate, use of social constructivist learning processes, and outcomes in nursing facilities receiving CONNECT with facilities receiving a falls education program alone. DESIGN AND METHODS Qualitative evaluation of a randomized controlled trial was done using a focus group design. Facilities (n = 8) were randomized to a falls education program alone (control) or CONNECT followed by FALLS (intervention). A total of 77 staff participated in 16 focus groups using a structured interview protocol. Transcripts were analyzed using framework analysis, and summaries for each domain were compared between intervention and control facilities. RESULTS Notable differences in descriptions of the learning climate included greater learner empowerment, appreciation of the role of all disciplines, and seeking diverse viewpoints in the intervention group. Greater use of social constructivist learning processes was evidenced by the intervention group as they described greater identification of communication weaknesses, improvement in communication frequency and quality, and use of sense-making by seeking out multiple perspectives to better understand and act on information. Intervention group participants reported outcomes including more creative fall prevention plans, a more respectful work environment, and improved relationships with coworkers. No substantial difference between groups was identified in safety culture, shared responsibility, and self-reported knowledge about falls. IMPLICATIONS CONNECT appears to enhance the use of social constructivist learning processes among nursing home staff. The impact of CONNECT on clinical outcomes requires further study.

Abstract
Bisphosphonates have been shown to reduce mortality in patients with osteoporotic fractures, but the mechanism is unclear. Bisphosphonates have immunomodulatory effects that may influence the development of vascular disease. We sought to determine if bisphosphonate use is associated with a reduced risk of myocardial infarction (MI) in a rheumatoid arthritis (RA) population with high prevalence of bisphosphonate use and vascular disease. Adult patients with RA enrolled in the National Data Bank for Rheumatic Diseases, a longitudinal study of RA patients enrolled continuously from U.S. rheumatology practices between 2003 and 2011, were included in the analysis (n = 19,281). Patients completed questionnaires every 6 months. including questions on medication use, demographic information, clinical information, and health status. MIs were confirmed by a central adjudicator. Among the 5689 patients who were treated with bisphosphonates at some time during the study period, the risk of MI while on bisphosphonate compared to when not on bisphosphonate was 0.56 (95% confidence interval [CI], 0.37-0.86; p < 0.01) after adjustment for multiple confounders. In models including all 19,281 treated and untreated patients, the adjusted risk of first MI was 0.72 (95% CI, 0.54-0.96; p = 0.02) and of all MIs it was 0.72 (95% CI, 0.53-0.97; p = 0.03) in bisphosphonate users compared to nonusers. This finding suggests a potential mechanism for the mortality reduction observed with bisphosphonate medications.

Abstract
OBJECTIVES/INTRODUCTION Demand for nursing home (NH) care by patients with end-stage renal disease (ESRD) is likely to increase with growing numbers of older adults initiating chronic dialysis. We completed a systematic review to summarize the literature on NH residents with ESRD. METHODS MEDLINE, CINAHL, EMBASE, and relevant conference proceedings were searched to identify articles using the following MESH terms or related key words in the title or abstract: "residential facilities", "renal dialysis", "renal replacement therapy", and "chronic kidney failure". We selected case control, cohort studies, and clinical trials that included older adults with ESRD (defined as those receiving chronic dialysis or those with stage 5 chronic kidney disease) living in residential care facilities. We abstracted information on study design, quality, and results. RESULTS Of 198 unique citations identified by the search strategy, 14 articles met eligibility criteria. Most articles were multicenter studies that were conducted in the 1990 s. One study focused on patients with stage 5 chronic kidney disease, and the remaining 13 studies focused on patients receiving chronic dialysis, of which eight studies included only those receiving peritoneal dialysis, four studies included patients receiving both peritoneal dialysis and hemodialysis, and one study included only patients receiving hemodialysis. All studies were observational, no clinical trials were identified, and study design limitations and heterogeneity within study populations were common. Summarizing results across these studies suggests that NH residents with ESRD have limited survival, particularly early after dialysis initiation. Functional impairment is highly prevalent in this population and independently associated with poor outcomes. CONCLUSIONS NH residents with ESRD appear to be a particularly vulnerable population, but current information on their prevalence, characteristics, and outcomes is limited. Further research is needed to provide a better understanding of modifiable predictors of survival and functional decline in this population.

Postoperative management of hip fractures: interventions associated with improved outcomes. BONEKEY REPORTS 2012; 1:241. [PMID: 24340216 PMCID: PMC3727802 DOI: 10.1038/bonekey.2012.241] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2012] [Revised: 11/16/2012] [Accepted: 11/16/2012] [Indexed: 11/09/2022]
Abstract
The annual number of hip fractures worldwide is expected to exceed 6 million by 2050. Currently, nearly 50% of hip fracture patients will develop at least one short-term complication including infection, delirium, venous thromboembolism (VTE), pressure ulcers or cardiovascular events. More than half will experience an adverse long-term outcomes including worsened ambulation or functional status, additional fractures and excess mortality. This paper summarizes current evidence for postoperative interventions attempting to improve these outcomes, including pain management, anemia management, delirium prevention strategies, VTE prophylaxis, rehabilitation type, nutritional supplements, anabolic steroids and secondary fracture prevention. Models of care that have been tested in this population including interdisciplinary orthogeriatric services, clinical pathways and hospitalist care are summarized. In general, good quality evidence supports routine use of VTE prophylaxis, and moderate quality evidence supports multifactorial delirium prevention protocols, and a conservative transfusion strategy. Aggressive pain control with higher doses of opiates and/or regional blocks are associated with lower delirium rates. Low-moderate quality evidence supports the use of clinical pathways, and dedicated orthogeriatric consultative services or wards. After hospital discharge, good quality evidence supports the use of bisphosphonates for secondary fracture prevention and mortality reduction. Rehabilitation services are important, but evidence to guide quantity, type or venue is lacking. Additional research is needed to clarify the role of nutritional supplements, anabolic steroids, home care and psychosocial interventions.

Abstract
Peer-mentoring groups are purported to enhance faculty productivity and retention, but the literature about implementation is sparse. Nominal Group Sessions (n=5) with 66 faculty members in different tracks developed prioritized lists of unmet professional development needs and potential group activities. Common items included mentor relationships, research skills, informal peer discussions of successes and challenges, and professional skills workshops. Items particular to specific academic tracks included integration of non-clinical faculty, and gaining recognition in non-research tracks.

Abstract
OBJECTIVES To assess the efficacy of once-yearly zoledronic acid (ZOL) 5 mg in increasing bone mineral density (BMD) in men with a recent hip fracture participating in the Health Outcomes and Reduced Incidence with Zoledronic Acid Once- Yearly Recurrent Fracture Trial and to compare the efficacy with that in women from the same study. DESIGN Randomized, placebo-controlled, double-blind trial. SETTING International multicenter. PARTICIPANTS Five hundred and eight men and 1,619 women within 90 days of surgical repair of low-trauma hip fracture in the same study (for comparison). INTERVENTION Once-yearly intravenous (IV) ZOL 5 mg (n = 248) or placebo (n = 260), loading dose of vitamin D, daily calcium, and vitamin D supplements. MEASUREMENT Changes in BMD. RESULTS Percentage change from baseline in total hip BMD at Months 12 and 24 was significantly higher with ZOL than with placebo (between-group difference, 2.0%, P = .003, and 3.8%, P = .002, respectively). Percentage change from baseline in femoral neck BMD at Month 24 was significantly higher with ZOL than with placebo (3.8%, P = .003). The BMD benefit was comparable with that observed in women in this study. New clinical fractures occurred in 36 (7.1%) participants (ZOL, n = 16; placebo, n = 20; P = .64). The ZOL safety profile was comparable with that of placebo, with no significant differences in cardiovascular or long-term renal function and a trend toward lower mortality in ZOL-treated men. CONCLUSION Once-yearly IV ZOL 5 mg increases bone mass at the hip and femoral neck in men within 90 days of repair of a low-trauma hip fracture. Increases were of a similar magnitude to those observed in women in the same study.

Abstract
UNLABELLED This study evaluated the benefits of ZOL versus placebo on health-related quality of life (HRQoL) among patients from HORIZON-RFT. At month 24 and end of the study visit, ZOL significantly improved patients' overall health state compared to placebo as assessed by the EQ-5D VAS. INTRODUCTION To evaluate the benefits of zoledronic acid (ZOL) versus placebo on health-related quality of life (HRQoL) among patients from The Health Outcomes and Reduced Incidence With Zoledronic Acid Once Yearly Recurrent Fracture Trial (HORIZON-RFT). METHODS In this randomized, double-blind, placebo-controlled trial, 2,127 patients were randomized to receive annual infusion of ZOL 5 mg (n = 1,065) or placebo (n = 1,062) within 90 days after surgical repair of low-trauma hip fracture. HRQoL was measured using EQ-5D Visual Analogue Scale (VAS) and utility scores (EuroQol instrument) at months 6, 12, 24, 36, and end of the study visit. Analysis of covariance model included baseline EQ-5D value, region, and treatment as explanatory variables. RESULTS At baseline, patients (mean age 75 years; 24% men and 76% women) were well matched between treatment groups with mean EQ-5D VAS of 65.82 in ZOL and 65.70 in placebo group. At the end of the study, mean change from baseline in EQ-5D VAS was greater for ZOL vs. placebo in all patients (7.67 ± 0.56 vs. 5.42 ± 0.56), and in subgroups of patients experiencing clinical vertebral fractures (8.86 ± 4.91 vs. -1.69 ± 3.42), non-vertebral fractures (5.03 ± 2.48 vs. -1.07 ± 2.16), and clinical fractures (5.19 ± 2.25 vs. -0.72 ± 1.82) with treatment difference significantly in favor of ZOL. EQ-5D utility scores were comparable for ZOL and placebo groups, but more patients on placebo consistently had extreme difficulty in mobility (1.74% for ZOL vs. 2.13% for placebo; p = 0.6238), self-care (4.92% vs. 6.69%; p = 0.1013), and usual activities (10.28% vs. 12.91%; p = 0.0775). CONCLUSION ZOL significantly improves HRQoL in patients with low-trauma hip fracture.

Abstract
OBJECTIVES To evaluate the cost-effectiveness of oral bisphosphonate therapy for osteoporosis in women at different ages and life expectancies. DESIGN A Markov model was used to analyze oral bisphosphonate treatment for 5 years compared to no intervention. Women at each age were divided into life expectancy quartiles: the lowest 1% to 25% (sickest group), the two middle 26% to 75% (average health group), and the highest 76% to 100% of life expectancy (healthiest group). Simulations were performed for hypothetical cohorts at 5-year intervals with starting ages between 50 and 90 and for each life expectancy group and followed for up to 100 years or until death. Data sources included published fracture rates, costs, utility values, and mortality risks. SETTING Computer simulation using a societal perspective. PARTICIPANTS Hypothetical cohort of women with various life expectancies beginning osteoporosis treatment between the age of 50 and 90 years. MEASUREMENTS Cost per quality-adjusted life years (QALY) gained for 5 years of bisphosphonate therapy compared to no treatment. Cost-effectiveness was defined at a willingness-to-pay of $50,000. RESULTS In the healthiest group, all costs were less than $18,000 per QALY. In the median quartiles of life expectancy, lifetime costs per QALY were less than $27,000 for patients at all ages; treatment became cost-saving at a starting age of 75 and remained so through a starting age of 85. Even in the sickest group, although osteoporosis treatment was not cost-saving, it remained cost-effective through a starting age of 90 with lifetime costs of less than $43,000 per QALY. CONCLUSION Treatment with an oral bisphosphonate for 5 years was cost-effective for all women, regardless of quartile of life expectancy. Advanced age should not prevent consideration of osteoporosis treatment based on cost effectiveness, and strategies to improve care, such as nurse-led screening programs or electronic medical record tools, are needed.

Abstract
Additional fractures after hip fracture are common, but little is known about the risk factors associated with these events. We determined the clinical risk factors associated with fracture following a low-trauma hip fracture and whether clinical risk factors for subsequent fracture were modified by zoledronic acid (ZOL). In this post hoc analysis of the HORIZON Recurrent Fracture trial, 2,127 men and women were randomized within 90 days of surgical hip fracture repair to receive intravenous ZOL 5 mg yearly or placebo. All patients received a loading dose of vitamin D and daily oral calcium and vitamin D supplements. In the multivariable model age, sex, BMI, femoral neck T score, and one or more fall risk factors were significant predictors of subsequent fracture. Race, history of prior fracture other than the index hip fracture, T score < -2.5 as a dichotomous variable, and type of index hip fracture were not associated with a different risk of subsequent fractures. Treatment with ZOL did not modify the impact of these risk factors. Well-established risk factors for fracture risk such as age, sex, BMI, and fall risk factors will also contribute to fracture risk in patients who have already suffered a hip fracture, while other prior fractures and T score < -2.5 are not predictive of subsequent fractures. Baseline risk factors in hip fracture patients were predictive of fracture in both ZOL- and placebo-treated participants, and there is no difference in the risk of subsequent fractures based on index hip fracture type.

Abstract
Regulatory oversight is intended to improve the health outcomes of nursing home residents, yet evidence suggests that regulations can inhibit mindful staff behaviors that are associated with effective care. We explored the influence of regulations on mindful staff behavior as it relates to resident health outcomes, and offer a theoretical explanation of why regulations sometimes enhance mindfulness and other times inhibit it. We analyzed data from an in-depth, multiple-case study including field notes, interviews, and documents collected in eight nursing homes. We completed a conceptual/thematic description using the concept of mindfulness to reframe the observations. Shared facility mission strongly impacted staff perceptions of the purpose and utility of regulations. In facilities with a resident-centered culture, regulations increased mindful behavior, whereas in facilities with a cost-focused culture, regulations reduced mindful care practices. When managers emphasized the punitive aspects of regulation we observed a decrease in mindful practices in all facilities.

Abstract
BACKGROUND Although an increased risk for death after hip fracture is well established, whether this excess mortality persists over time is unclear. PURPOSE To determine the magnitude and duration of excess mortality after hip fracture in older men and women. DATA SOURCES Electronic search of MEDLINE and EMBASE for English and non-English articles from 1957 to May 2009 and manual search of article references. STUDY SELECTION Prospective cohort studies were selected by 2 independent reviewers. The studies had to assess mortality in women (22 cohorts) or men (17 cohorts) aged 50 years or older with hip fracture, carry out a life-table analysis, and display the survival curves of the hip fracture group and age- and sex-matched control groups. DATA EXTRACTION Survival curve data and items relevant to study validity and generalizability were independently extracted by 2 reviewers. DATA SYNTHESIS Time-to-event meta-analyses showed that the relative hazard for all-cause mortality in the first 3 months after hip fracture was 5.75 (95% CI, 4.94 to 6.67) in women and 7.95 (CI, 6.13 to 10.30) in men. Relative hazards decreased substantially over time but did not return to rates seen in age- and sex-matched control groups. Through use of life-table methods, investigators estimated that white women having a hip fracture at age 80 years have excess annual mortality compared with white women of the same age without a fracture of 8%, 11%, 18%, and 22% at 1, 2, 5, and 10 years after injury, respectively. Men with a hip fracture at age 80 years have excess annual mortality of 18%, 22%, 26%, and 20% at 1, 2, 5, and 10 years after injury, respectively. LIMITATIONS Cohort studies varied, sometimes markedly, in size, duration of observation, selection of control populations, ascertainment of death, and adjustment for comorbid conditions. Only published data that displayed findings with survival curves were examined. Publication bias was possible. CONCLUSION Older adults have a 5- to 8-fold increased risk for all-cause mortality during the first 3 months after hip fracture. Excess annual mortality persists over time for both women and men, but at any given age, excess annual mortality after hip fracture is higher in men than in women.

Abstract
OBJECTIVES To determine the efficacy of once-yearly intravenous zoledronic acid (ZOL) 5 mg in reducing risk of clinical vertebral, nonvertebral, and any clinical fractures in elderly osteoporotic postmenopausal women. DESIGN A post hoc subgroup analysis of pooled data from the Health Outcome and Reduced Incidence with Zoledronic Acid One Yearly (HORIZON) Pivotal Fracture Trial and the HORIZON Recurrent Fracture Trial. SETTING Multicenter, randomized, double-blind, placebo-controlled trials. PARTICIPANTS Postmenopausal women (aged > or =75) with documented osteoporosis (T-score < or =-2.5 at femoral neck or >/=1 prevalent vertebral or hip fracture) or a recent hip fracture. INTERVENTION Patients were randomized to receive an intravenous infusion of ZOL 5 mg (n=1,961) or placebo (n=1,926) at baseline and 12 and 24 months. MEASUREMENTS Primary endpoints were incidence of clinical vertebral and nonvertebral and any clinical fracture after treatment. RESULTS At 3 years, incidence of any clinical, clinical vertebral, and nonvertebral fracture were significantly lower in the ZOL group than in the placebo group (10.8% vs 16.6%, 1.1% vs 3.7%, and 9.9% vs 13.7%, respectively) (hazard ratio (HR)=0.65, 95% confidence interval (CI)=0.54-0.78, P<.001; HR=0.34, 95% CI=0.21-0.55, P<.001; and HR=0.73, 95% CI=0.60-0.90, P=.002, respectively). The incidence of hip fracture was lower with ZOL but did not reach statistical significance. The incidence rate of postdose adverse events were higher with ZOL, although the rate of serious adverse events and deaths was comparable between the two groups. CONCLUSION Once-yearly intravenous ZOL 5 mg was associated with a significant reduction in the risk of new clinical fractures (vertebral and nonvertebral) in elderly postmenopausal women with osteroporosis.

Abstract
OBJECTIVES To develop order entry algorithms for five common nursing home problems and to test their acceptance, use, and preliminary effect on nine quality indicators and resource utilization. DESIGN Pre-post, quasi-experimental study. SETTING Two Department of Veterans Affairs nursing homes. PARTICIPANTS Randomly selected residents (N=265) with one or more target conditions and 42 nursing home providers. INTERVENTION Expert panels developed computerized order entry algorithms based on clinical practice guidelines. Each was displayed on a single screen and included an array of diagnostic and treatment options and means to communicate with the interdisciplinary team. MEASUREMENTS Medical records were abstracted for the 6 months before and after deployment for quality indicators and resource utilization. RESULTS Despite positive provider attitudes toward the computerized order entry algorithms, their use was infrequent and varied according to condition: falls (73.0%), fever (9.0%), pneumonia (8.0%), urinary tract infection (7.0%), and osteoporosis (3.0%). In subjects with falls, trends for improvements in quality measures were observed for six of the nine measures: measuring orthostatic blood pressure (17.5-30.0%, P=.29), reducing neuroleptics (53.8-75.0%, P=.27), reducing sedative-hypnotics (16.7-50.0%, P=.50), prescription of calcium (22.5-32.5%, P=.45), vitamin D (20.0-35.0%, P=.21), and external hip protectors (25.0-47.5%, P=.06). Little improvement was observed in the other conditions (documentation of vital signs, physical therapy referrals, or reduction of benzodiazepines or antidepressants). There was no change in resource utilization. CONCLUSION Computerized order entry algorithms were used infrequently, except for falls. Further study may determine whether their use leads to improved care.

Antifracture efficacy and reduction of mortality in relation to timing of the first dose of zoledronic acid after hip fracture. J Bone Miner Res 2009; 24:1308-13. [PMID: 19257818 PMCID: PMC5770985 DOI: 10.1359/jbmr.090209] [Citation(s) in RCA: 95] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2008] [Revised: 12/19/2008] [Accepted: 02/11/2009] [Indexed: 11/18/2022]
Abstract
Annual infusions of zoledronic acid (5 mg) significantly reduced the risk of vertebral, hip, and nonvertebral fractures in a study of postmenopausal women with osteoporosis and significantly reduced clinical fractures and all-cause mortality in another study of women and men who had recently undergone surgical repair of hip fracture. In this analysis, we examined whether timing of the first infusion of zoledronic acid study drug after hip fracture repair influenced the antifracture efficacy and mortality benefit observed in the study. A total of 2127 patients (1065 on active treatment and 1062 on placebo; mean age, 75 yr; 76% women and 24% men) were administered zoledronic acid or placebo within 90 days after surgical repair of an osteoporotic hip fracture and annually thereafter, with a median follow-up time of 1.9 yr. Median time to first dose after the incident hip fracture surgery was approximately 6 wk. Posthoc analyses were performed by dividing the study population into 2-wk intervals (calculated from time of first infusion in relation to surgical repair) to examine effects on BMD, fracture, and mortality. Analysis by 2-wk intervals showed a significant total hip BMD response and a consistent reduction of overall clinical fractures and mortality in patients receiving the first dose 2-wk or later after surgical repair. Clinical fracture subgroups (vertebral, nonvertebral, and hip) were also reduced, albeit with more variation and 95% CIs crossing 1 at most time points. We concluded that administration of zoledronic acid to patients suffering a low-trauma hip fracture 2 wk or later after surgical repair increases hip BMD, induces significant reductions in the risk of subsequent clinical vertebral, nonvertebral, and hip fractures, and reduces mortality.
