Progressing to Objective Measures of Daily Mobility in Hospitalized Older Adults.

Accurate mobility assessment of hospitalized older adults is necessary to aid nurses in planning and providing appropriate mobility support; however, nurses cite lack of resources and time limitations as barriers. Accelerometry enables a detailed objective measurement of predominant hospital mobility activities in the older adult population, such as percent time sitting, and the sit-to-stand (STS) transition. The current exploratory study examined the use of a novel, unobtrusive accelerometry technique to obtain postural and STS metrics on 27 older adults during their hospital stay. Total device wear time in the hospital was 96.2%. Participants spent 60.3% time lying, 20.3% time sitting, 5.3% time standing, and 2% time stepping during hospitalization, and, on average, completed the STS transition 20 times (SD = 13) per 24-hour period. There were no participant complaints about wearing the device. Our exploratory study shows accelerometry provides automated, continuous data and may support accurate nursing assessment of patient mobility. [Journal of Gerontological Nursing, 48(5), 35-41.].

Tailored physical activity behavior change interventions: challenges and opportunities.

A physically active lifestyle provides innumerable benefits; yet, few individuals are physically active enough to reap those benefits. Tailored physical activity interventions may address low rates of physical activity by offering individualized strategies that consider a person's characteristics, needs, preferences, and/or context, rather than the traditional one-size-fits-all approach. However, the tailoring methodology is in its nascency, and an understanding of how best to develop such interventions is needed. In this commentary, we identify future directions to enhance the impact of tailored interventions designed to increase physical activity participation. A multi-country collaborative was established to review the literature and discuss an agenda for future research. Two overarching research opportunities are suggested for improving the development of tailored, behavioral physical activity interventions: (a) optimize the engagement of diverse knowledge users in intervention co-design and (b) examine ethical considerations that may impact the use of technology to support tailored physical activity delivery. Specifically, there is a need for better reporting and evaluation of knowledge user involvement alongside targeting diversity in the inclusion of knowledge users. Furthermore, while technology boasts many opportunities to increase the scale and precision of interventions, examinations of how it impacts recipients' experiences of and participation in tailored interventions are needed to ensure the benefits of technology use outweigh the risks. A better understanding of these research areas will help ensure that the diverse needs of individuals are met, technology is appropriately used to support tailoring, and ultimately it improves the effectiveness of tailored physical activity interventions.

Being physically active has many social, emotional, and health benefits, but very few individuals are active enough to see those benefits. Using interventions that are tailored, in other words, individualized to a person's characteristics, needs, preferences, and/or situation, may help improve physical activity participation rates. However, a better understanding of how to do tailoring is needed. Our collaboration reviewed the literature and convened to suggest two key opportunities to better understand how tailored approaches to physical activity can be done: (a) improve engagement of those who the research is intended for and (b) understand the ethical impacts and patient/provider experience of using technology to support tailoring.

Exploring the Relationship Between Contact Frequency, Leader-Member Relationships, and Patient Safety Culture.

OBJECTIVE: This study uses Leader-Member Exchange theory to explore the associations between contact frequency (CF) of nurse leaders and their team members, leader-member relationship, and patient safety culture. BACKGROUND: Leader-member relationships are an important part of patient safety culture development. The behaviors of leaders to achieve these relationships are unknown. This study explores CF as a leader behavior to improve patient safety culture. METHODS: Cross-sectional survey of bedside nurses (N = 746) from an 8-hospital system. RESULTS: A significant association was found between relationship strength and patient safety culture; CF's effect on relationship and patient safety culture was demonstrated. CONCLUSION: Contact frequency may support relationships between leaders and members and improve patient safety culture on nursing units. Future studies should explore factors that could be enhancing and limiting CF.

STepped exercise program for patients with knee OsteoArthritis (STEP-KOA): protocol for a randomized controlled trial.

BACKGROUND: Physical therapy (PT) and other exercise-based interventions are core components of care for knee osteoarthritis (OA), but both are underutilized, and some patients have limited access to PT services. This clinical trial is examining a STepped Exercise Program for patients with Knee OsteoArthritis (STEP-KOA). This model of care can help to tailor exercise-based interventions to patient needs and also conserve higher resource services (such as PT) for patients who do not make clinically relevant improvements after receiving less costly interventions. METHODS / DESIGN: Step-KOA is a randomized trial of 345 patients with symptomatic knee OA from two Department of Veterans Affairs sites. Participants are randomized to STEP-KOA and Arthritis Education (AE) Control groups with a 2:1 ratio, respectively. STEP-KOA begins with 3 months of access to an internet-based exercise program (Step 1). Participants not meeting response criteria for clinically meaningful improvement in pain and function after Step 1 progress to Step 2, which involves bi-weekly physical activity coaching calls for 3 months. Participants not meeting response criteria after Step 2 progress to in-person PT visits (Step 3). Outcomes will be assessed at baseline, 3, 6 and 9 months (primary outcome time point). The primary outcome is the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), and secondary outcomes are objective measures of physical function. Linear mixed models will compare outcomes between the STEP-KOA and AE control groups at follow-up. We will also evaluate patient characteristics associated with treatment response and conduct a cost-effectiveness analysis of STEP-KOA. DISCUSSION: STEP-KOA is a novel, efficient and patient-centered approach to delivering exercise-based interventions to patients with knee OA, one of the most prevalent and disabling health conditions. This trial will provide information on the effectiveness of STEP-KOA as a novel potential model of care for treatment of OA.

Composite measures of physical activity and pain associate better with functional assessments than pain alone in knee osteoarthritis.

INTRODUCTION: Recent research showed that physical activity (PA)-adjusted pain measures were more strongly associated with radiographic osteoarthritis (OA) severity than an unadjusted pain measure. This exploratory study examined whether PA-adjusted pain measures were more closely associated with other key OA-related measures, compared to unadjusted pain scores. METHOD: Participants were 122 Veterans (mean age = 61.2 years, 88.5% male) with knee OA. Baseline Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores were adjusted for accelerometer-derived daily: (1) step counts, (2) minutes of any activity, (3) minutes of moderate or greater intensity activity, (4) minutes of light intensity activity, and (5) energy expenditure. Partial correlations, adjusted for age, sex, and body mass index, estimated associations of unadjusted and PA-adjusted WOMAC pain scores with functional assessments (6-minute walk test, 8-foot walk test, chair stand test, satisfaction with physical function), fatigue (Brief Fatigue Inventory), and anxiety/depressive symptoms (single item). RESULTS: Significant (p < 0.05) associations were found in 29 of 36 of models. For the four function-related assessments, step count and energy expenditure-adjusted WOMAC pain scores had stronger associations (partial rs = 0.24-0.48) than WOMAC pain score (partial rs = 0.19-0.25). For fatigue and anxiety/depressive symptoms, WOMAC pain score had stronger, positive associations than most PA-adjusted pain scores. Of the PA-adjusted measures, the strongest associations overall were observed for step count and energy expenditure. CONCLUSION: PA-adjusted pain scores may have particular value for OA studies involving functional assessments, whereas unadjusted WOMAC pain scores are more closely associated with psychological symptoms. This has implications for measurement in clinical OA studies. TRIAL REGISTRATION: NCT01058304 KEY POINTS: • Among patents with osteoarthritis, physical activity-adjusted pain measures (particularly those adjusted for step count and energy expenditure) were more strongly associated with measures of physical function, compared to unadjusted pain scores, whereas unadjusted pain score was more strongly associated with a measure of psychological symptoms. • In clinical osteoarthritis research, the most appropriate or sensitive symptom measure (pain vs. physical activity-adjusted pain) may depend on the type of intervention or outcome being studied.

A pilot study examining activity monitor use in older adults with heart failure during and after hospitalization.

Our study examined feasibility and acceptability of continuous objective activity monitoring during hospitalization and after discharge in older adults with heart failure. Recruitment rate was 49.2% of eligible patients with a 93.1% retention rate. Twenty-seven older patients admitted with heart failure (78 ±â€¯9.8 years; 51.8% female) wore two inclinometric accelerometers to record posture in-hospital and an ankle accelerometer to record ambulatory activity in-hospital and 30-days after discharge. During hospitalization, participants had 96.2% recorded wear time for postural accelerometers, and 99% for the ankle accelerometer. During the post-discharge period, there was 92% recorded wear time of the ankle accelerometer. Themes identified by participants were ease of wear, compatibility with hospital technology, remembering device/device use, and need for feedback/curiosity. Our study demonstrates feasibility and acceptability of continuous objective monitoring during hospitalization and at home in this clinical population.

Factors associated with physical activity in African Americans with hypertension.

BACKGROUND: Pharmacological management only controls 58% of those with hypertension. Combining pharmacological therapy with physical activity is important in controlling hypertension. AIM: To examine factors associated with physical activity (PA) adherence in African Americans (AAs) with hypertension and antihypertensive medication adherence. METHODS: A cross-sectional descriptive correlational design was used to examine if systolic BP, co-morbidities, serum creatinine and potassium, education, depression, locus of control, and social support explained PA adherence in a convenience sample of AAs (N = 77) aged 55 to 84. All completed: demographic data, PA visual analog scale (VAS-PA); Multidimensional Health Locus of Control Scale; Patient Health Question-9 Depression Instrument. Physiological data and co-morbidities were also collected. RESULTS: A third (n = 26) had systolic BP over 140 mm/Hg. The model explained 26% variance in adherence to PA (F = 3.378 [8, 68]; p = .003) with creatinine (p < .05), depression (p < .01), and social support (p < .05) as significant. Differences in VAS-PA scores between levels of depression were significant (F = 4.707 [269], p = .012; Eta2 = 0.12). Those with no depression had significantly higher PA adherence (M = 88.26, SD = 18.97) compared to mildly depressed (M = 70.24, SD 27.71) and moderately depressed (M = 66.83, SD = 23.31). CONCLUSIONS: Clinicians should promote PA as an adjunct to medications for effective control of hypertension in AAs. Screening and intervening for depression are important when examining adherence to PA in AAs with hypertension.

Association of Posture and Ambulation With Function 30 Days After Hospital Discharge in Older Adults with Heart Failure.

PURPOSE: The aim of this work was to investigate the predictive value of in-hospital posture and ambulatory activity for 30 days following discharge on functional status in older patients with heart failure. METHODS AND RESULTS: We undertook a prospective observational pilot study of 27 patients (78 ± 9.8 y, 51.8% female) admitted with heart failure. Participants wore 2 inclinometric accelerometers to record posture in-hospital and an ankle accelerometer to record ambulatory activity in-hospital and 30 days after discharge. Function was assessed on the day after discharge (Timed Up and Go [TUG], Short Physical Performance Battery [SPPB], hand grip strength) and 30 days after discharge. Length of stay was 5.1 ± 3.9 days. Participants spent 63.0 ± 19.2% of their hospital time lying down, 30.2 ± 18.7% sitting, 5.3 ± 4.2% standing, and 1.9 ± 8.6% ambulating. Thirty-day mean post-discharge stepping was 4890 ± 2285 steps/day. Each 10% increase in hospital lying time was associated with 0.7 s longer TUG time (95% confidence interval [CI] 0.2-1.9) at 30 days. Each 1000 additional daily steps in the post-discharge period was associated with a 0.8-point higher SPPB score (95% CI 0.1-1.0) at 30 days. Handgrip strength was unchanged. CONCLUSIONS: Older patients with heart failure were sedentary during hospitalization, which may contribute to decreased functional performance. Physical activity after discharge may minimize this negative effect.

Early Mobility in the Hospital: Lessons Learned from the STRIDE Program.

Immobility during hospitalization is widely recognized as a contributor to deconditioning, functional loss, and increased need for institutional post-acute care. Several studies have demonstrated that inpatient walking programs can mitigate some of these negative outcomes, yet hospital mobility programs are not widely available in U.S. hospitals. STRIDE (assiSTed eaRly mobIlity for hospitalizeD older vEterans) is a supervised walking program for hospitalized older adults that fills this important gap in clinical care. This paper describes how STRIDE works and how it is being disseminated to other hospitals using the Replicating Effective Programs (REP) framework. Guided by REP, we define core components of the program and areas where the program can be tailored to better fit the needs and local conditions of its new context (hospital). We describe key adaptations made by four hospitals who have implemented the STRIDE program and discuss lessons learned for successful implementation of hospital mobility programs.

Validation of Consumer-Based Hip and Wrist Activity Monitors in Older Adults With Varied Ambulatory Abilities.

BACKGROUND: The accuracy of step detection in consumer-based wearable activity monitors in older adults with varied ambulatory abilities is not known. METHODS: We assessed the validity of two hip-worn (Fitbit One and Omron HJ-112) and two wrist-worn (Fitbit Flex and Jawbone UP) activity monitors in 99 older adults of varying ambulatory abilities and also included the validity results from the ankle-worn StepWatch as a comparison device. Nonimpaired, impaired (Short Physical Performance Battery Score < 9), cane-using, or walker-using older adults (62 and older) ambulated at a self-selected pace for 100 m wearing all activity monitors simultaneously. The criterion measure was directly observed steps. Intraclass correlation coefficients (ICC), mean percent error and mean absolute percent error, equivalency, and Bland-Altman plots were used to assess accuracy. RESULTS: Nonimpaired adults steps were underestimated by 4.4% for StepWatch (ICC = 0.87), 2.6% for Fitbit One (ICC = 0.80), 4.5% for Omron HJ-112 (ICC = 0.72), 26.9% for Fitbit Flex (ICC = 0.15), and 2.9% for Jawbone UP (ICC = 0.55). Impaired adults steps were underestimated by 3.5% for StepWatch (ICC = 0.91), 1.7% for Fitbit One (ICC = 0.96), 3.2% for Omron HJ-112 (ICC = 0.89), 16.3% for Fitbit Flex (ICC = 0.25), and 8.4% for Jawbone UP (ICC = 0.50). Cane-user and walker-user steps were underestimated by StepWatch by 1.8% (ICC = 0.98) and 1.3% (ICC = 0.99), respectively, where all other monitors underestimated steps by >11.5% (ICCs < 0.05). CONCLUSIONS: StepWatch, Omron HJ-112, Fitbit One, and Jawbone UP appeared accurate at measuring steps in older adults with nonimpaired and impaired ambulation during a self-paced walking test. StepWatch also appeared accurate at measuring steps in cane-users.

An integrative review of physical activity/exercise intervention effects on function and health-related quality of life in older adults with heart failure.

This paper reviews randomized, controlled trials (RCTs) that have used a physical activity/exercise intervention in older adults with heart failure and reported outcomes of physical function and/or health-related quality of life. An integrative review was necessary because a literature search indicated no reviews have been done regarding these outcomes which are deemed very important by the older adult population. Computerized database search strategies by authors between 2002 and 2015 resulted in 163 studies, with 12 meeting inclusion criteria. Interventions were performed in clinic and home-based, group and/or individual settings with durations from three to 12 months. Interventions were varied. Common methodological weaknesses of the studies include lack of theory guiding the intervention, small sample and low minority representation. Strengths included detailed intervention methods. There was a moderate effect of interventions with no reported adverse effects. Further work is essential to identify successful strategies to support older adults with heart failure to increase their physical activity levels.

Intervention markers of physical activity maintenance in older adults.

OBJECTIVES: To identify intervention components that may promote longterm changes of physical activity among older adults in a behavioral theory-based physical activity trial. METHODS: Participants (N = 24; aged 65 ± 8.79 years) shared perceptions of intervention components at the end of the intervention and physical activity was assessed at 18 months. Mixed-methods analyses using a pragmatic content analysis of interview data were conducted. RESULTS: Active study participants (25%) cited more specific goals/actions to achieve goals and more social support from family/friends, and had significantly higher self-determined motivation mean scores at 18 months than insufficiently active study participants (75%). CONCLUSIONS: Specific goal-setting behaviors and social support from family/friends may be key elements of physical activity maintenance in older adults.
