Pet Ownership and Maintenance of Physical Function in Older Adults-Evidence From the Baltimore Longitudinal Study of Aging (BLSA).

Background and Objectives: Pet ownership or human-animal interaction has been associated with better health outcomes in individuals with disease or disability. We hypothesized that pet ownership, as well as dog ownership and cat ownership separately, are associated with maintaining physical function, and leisure time physical activity and that among dog owners, dog walking is associated with maintaining these outcomes for generally healthy community-dwelling older adults participating in the Baltimore Longitudinal Study of Aging. Research Design and Methods: A total of 637 men (44.1%) and women aged 50-100 years (M = 68.3, standard deviation [SD] = 9.6) completed a comprehensive pet ownership questionnaire that ascertained pet ownership history 10-13 years and had serial assessments of physical function every 1-4 years prior. Linear or generalized linear mixed models with time varying pet ownership were used to examine change in physical function over a mean of 7.5 years (range 1-13, SD = 3.6) according to pet ownership. Results: Pet owners (n = 185) were significantly younger (p < .001) and had fewer comorbidities (p = .03) than nonowners; thus, age and comorbidities were included as covariates in the longitudinal analyses. Physical function and leisure time physical activity declined with aging across all outcomes (p < .001); the decline was slower among pet owners in overall physical performance (p < .001), rapid gait speed (p = .03), usual gait speed (p = .032), cardiorespiratory fitness (p < .001), and physical well-being (p = .002) controlling for age and comorbidities. Changes in leisure time physical activities with aging did not differ between pet owners and nonowners. Dog walking was not independently related to the maintenance of physical function or leisure time physical activity with aging. Discussion and Implications: This study provides the first longitudinal evidence that pet ownership is associated with maintained physical function among community-dwelling generally healthy older adults.

Intimate Partner Violence Training and Readiness to Respond among Students, Staff, and Faculty in Three Institutions in the United States.

Intimate partner violence (IPV) is a significant public health concern; however, limited studies have explored perceptions and experiences towards IPV among students, staff, administrators, and faculty across diverse disciplines at institutions of higher education. The purposes of this study were to (1) assess experiences of IPV among a sample of students, staff/administrators, and faculty and (2) examine the relationship among attitudes, actual and perceived knowledge, awareness, training, readiness, and personal experiences with IPV in this sample. Participants were recruited from an urban university and two university-affiliated medical institutions to participate in an online survey. Bivariate and multivariate associations were assessed. Structural Equation Modeling (SEM) was used to examine direct and indirect effects of perceived and actual knowledge and personal experiences with IPV. Of the 216 respondents, 42.6% reported personally experiencing IPV and 34.3% reported having witnessed IPV. Over 34% of participants never received training on IPV. The sub-sample with training received between one and more than 15 hours of training. Standardized total effect of training on attitudes and awareness was ß = 0.42 (95% confidence interval [CI] = 0.30-0.51), the combined indirect effects was ß = 0.18 (95% CI = 0.10-0.27) and the direct effects of ß=0.23 (95% CI = 0.12-0.34), indicating that hours of training was highly associated with the participants' perceived knowledge and actual knowledge, which improved their attitudes and awareness towards IPV survivors. Our findings suggest the need for campus-wide formal training on IPV to better prepare members in higher education to accurately identify, assess, and intervene to protect victims of abuse. Interprofessional approaches are needed that focus on the multiple and intersecting needs of victims of violence and should also enhance professional self-efficacy and increase readiness to respond to IPV survivors.

A National Survey of Medication Dosage Calculation Teaching Methods and Competency Criteria on Nursing Student Success: Recommendations for Nurse Educators.

AIM: The purpose of this study was to synthesize the current landscape of medication dosage calculation (MDC) education for prelicensure nursing students in the United States. BACKGROUND: There is little consistency in the format of MDC education and evaluation in prelicensure nursing education, yet consequences of not passing MDC exams can affect the number of graduating nurses. Consequences can include withdrawal from the course, delayed progression of a semester or more, or dismissal from the nursing program. METHOD: An electronic survey was emailed to prelicensure administrators of 1,620 associate, bachelor's, and master's entry programs in the United States. RESULTS: Surveys were received from 210 programs. Results confirmed inconsistent methods used to teach and evaluate MDC competency. CONCLUSION: Inconsistent teaching methods and competency criteria can affect retention and subsequent growth of the nursing workforce. Based on the characteristics associated with MDC success, recommendations are made for nurse educators.

Racial Differences in Antidepressant Use in Nursing Facility Residents With Moderate to Severe Cognitive Impairment.

Objective To describe and compare the use of antidepressants between Black or African descent and White nursing facility residents with moderate to severe cognitive impairment. Design This was a secondary data analysis using baseline data from the Function and Behavior Focused Care for Nursing Facility Residents with Dementia randomized control trial. Setting Participants were recruited from 10 urban and two rural nursing facilities from Maryland. Methods Participants had to be 55 years of age or older, English-speaking, reside in long-term care at time of recruitment, and score a 15 or less on the Mini Mental-State Examination. A total of 336 residents participated at baseline. Data were collected by a research evaluator through observation, proxy report from staff caring for the resident the day of testing, and patient charts. Main Outcomes A significant difference of antidepressant use between Black or African descent and White nursing facility residents with moderate to severe cognitive impairment would be noted when controlling for depression, age, gender, functional status, agitation, and number of co-morbidities. Results In adjusted models, Black or African descent residents were less likely to be prescribed antidepressants compared with White residents. Conclusion Racial differences were noted regarding antidepressant use among nursing facility residents with moderate to severe cognitive impairment, but it is unknown if race could impact prescribing practices when indications for use are known. Further research is needed to ascertain if knowing the specific indications for use might contribute to racial disparities with antidepressant prescribing in nursing facility residents with moderate to severe cognitive impairment.

Giving birth during the COVID-19 pandemic, perspectives from a sample of the United States birthing persons during the first wave: March-June 2020.

BACKGROUND: The COVID-19 pandemic forced hospitals in the United States to adjust policy and procedure in order to provide safe care and prevent the spread of disease. At the beginning of the pandemic, media and case reports described pressure for medical interventions, visitor restrictions, separation from newborns, and an increase in patient demand for community birth (home and birth center). The purpose of this study was to describe birth experiences during the COVID-19 pandemic centering the birthing person's perspective. METHODS: A survey was e-mailed to users of the Ovia Pregnancy app reaching a national convenience sample who gave birth between March 1, 2020, and June 11, 2020. Survey topics included birth location, the Mothers on Respect index, and open-ended questions capturing patient perspectives on the pandemic's effect on their birth experiences. Differences were assessed based on state-level COVID rate and by race. Content analysis was performed to analyze open-ended responses. RESULTS: Respondents from highly impacted COVID-19 states more frequently changed or considered changing their birth location. Racial differences were also found with Black respondents reporting significantly more preterm births and lower respect scores when compared to White respondents. Six themes emerged from the content analysis: Institutional Policies, Changes in Care, Hospital Staff Interactions, Sub-par Care, Issues of Support, and Mental Health. DISCUSSION: The health care community must continue to adapt policies and procedures to best support birthing patients during the COVID-19 pandemic. The community must also continue to address the reality that Black patients receive less respectful care compared with White patients.

Challenges in the Triage Care of Low-Risk Laboring Patients: A Comparison of 2 Models of Practice.

Triage and the timing of admission of low-risk pregnant women can affect the use of augmentation, epidural, and cesarean. The purpose of this analysis was to explore these outcomes in a community hospital by the type of provider staffing triage. This was a retrospective cohort study of low-risk nulliparous women with a term, vertex fetus laboring in a community hospital. Bivariate and multivariable statistics evaluated associations between triage provider type and labor and birth outcomes. Patients in this sample (N = 335) were predominantly White (89.5%), with private insurance (77.0%), and married (71.0%) with no significant differences in these characteristics by triage provider type. Patients admitted by midwives had lower odds of oxytocin augmentation (adjusted odds ratio [aOR] = 0.50, 95% confidence interval [CI] = 0.29-0.87), epidural (aOR = 0.29, 95% CI = 0.12-0.69), and cesarean birth (aOR = 0.308, 95% CI = 0.14-0.67), compared with those triaged by physicians after controlling for patient characteristics and triage timing. This study provides additional context to midwives as labor triage providers for healthy, low-risk pregnant individuals; however, challenges persisted with measurement. More research is needed on the specific components of care during labor that support low-risk patients to avoid medical interventions and poor outcomes.

A Cluster Randomized Controlled Trial Testing the Impact of Function and Behavior Focused Care for Nursing Home Residents With Dementia.

OBJECTIVE: The purpose of this study was to test the effectiveness of the Function and Behavior Focused Care for the Cognitively Impaired (FBFC-CI) intervention on function, physical activity, and behavioral symptoms among nursing home residents with dementia, and to explore the adoption of the intervention at the facility level. DESIGN: This study was a clustered, randomized controlled trial with a repeated measures design that was implemented in 12 nursing homes randomized to either treatment (FBFC-CI) or educational control [Function and Behavior Focused Care Education (FBFC-ED)]. SETTING AND PARTICIPANTS: Twelve nursing homes (6 treatment and 6 control) and 336 residents (173 treatment and 163 control) with moderate to severe cognitive impairment. MEASURES: Outcomes included functional ability (Barthel Index), physical activity (actigraphy and survey), behavioral symptoms (Resistiveness to Care Scale, Cohen-Mansfield Agitation Inventory, Cornell Scale for Depression in Dementia), and psychotropic medication use. RESULTS: The participants were 82.6 (SD = 10.1) years of age, mostly female, and were moderate to severely cognitively impaired (Mini-Mental State Exam of 7.8, SD = 5.1). There was a significantly greater increase in time spent in total activity (P = .004), moderate activity (P = .012), light activity (P = .002), and a decrease in resistiveness to care (P = .004) in the treatment versus control group at 4 months. There was no change in mood, agitation, and the use of psychotropic medications. There was some evidence of adoption of the intervention at treatment sites. CONCLUSIONS AND IMPLICATIONS: This study provides some support for the use of the FBFC-CI Intervention to increase time spent in physical activity and decrease resistive behaviors during care commonly noted among nursing home residents with moderate to severe cognitive impairment.

Mobile Technology Care Coordination of Long-Term Services and Support: Cluster Randomized Clinical Trial.

The purpose of the study was to assess whether the effects of a mobile predictive intervention used by Service Coordinators (SCs) reduce hospital utilization in a Medicaid Long-Term Services and Supports (LTSS) population in Baltimore city during a 5-month intervention. SC participants (n = 11) were recruited to treatment or control groups. LTSS clients (n = 420) followed their SC randomization assignment. Utilization data were obtained from the Maryland Chesapeake Regional Information System for our Patients (CRISP) Health Information Exchange (HIE) system and linked to service coordination records. Study groups were similar in age, gender, race, and years receiving LTSS. SCs' satisfaction with use of the mobile tool was surveyed. SC perceptions were neutral (mean scores ranged from 2.3 to 3.3 on a 5-point scale). No significant differences between groups were observed for all utilization metrics. The mobile technology software system used in this study did not improve health care utilization for a LTSS population needing ongoing clinical and social services coordinated care.

Risk of Renal Failure Within 10 or 20 Years of Systemic Lupus Erythematosus Diagnosis.

OBJECTIVE: The frequency of endstage renal disease (ESRD) from systemic lupus erythematosus (SLE) in the United States has not improved over the last few decades in large population datasets. Understanding the risk factors for renal failure in SLE could lead to earlier detection of lupus nephritis and potentially more effective treatments in those with markers of poor prognosis. METHODS: The Hopkins Lupus Cohort, comprising 2528 patients was used. One hundred fifty-one patients experienced renal failure after SLE diagnosis, defined as dialysis or renal transplant. We estimated the risk of renal failure in subgroups defined by demographics, laboratory tests, and the American College of Rheumatology/Systemic Lupus International Collaborating Clinics (ACR/SLICC) classification criteria satisfied within 1 year of SLE diagnosis. RESULTS: The overall incidence of renal failure within 20 years of SLE diagnosis was 8.4%. The risk was much higher (20.0%) among those who experienced proteinuria within the first year of diagnosis. Demographic predictors included African American ethnicity [rate ratio (RR) 1.82, P = 0.0012] and age ≥ 40 years at SLE diagnosis (RR 0.51 vs those with diagnosis at < 30 yrs of age, P = 0.019). Among immunologic markers, low C3 was a strong predictor of renal failure (RR 2.00, P = 0.0011). CONCLUSION: Proteinuria within the first year of diagnosis of SLE is one of the most important predictors of ESRD. Our data also confirm African American ethnicity, younger age at SLE diagnosis, and low C3 as strong predictors of renal failure.

Testing the Impact of FFC-AL-EIT on Psychosocial and Behavioral Outcomes in Assisted Living.

BACKGROUND: This study tested the impact of Function Focused Care for Assisted Living Using the Evidence Integration Triangle (FFC-AL-EIT) on: (1) care interactions between residents and direct care staff; and (2) behavior and psychological symptoms associated with dementia among residents. DESIGN: This was a randomized controlled trial. SETTING: A total of 59 assisted living facilities in Maryland, Pennsylvania, and Massachusetts participated. PARTICIPANTS: The sample included 550 mostly White (98%), female (69%) residents with a mean age of 89.30 (standard deviation = 7.63) years. INTERVENTION: The four-step FFC-AL-EIT intervention was implemented by a function focused care nurse facilitator working with a facility champion over 12 months. The steps included: (1) environment and policy assessments; (2) education; (3) establishing resident function focused care service plans; and (4) mentoring and motivating. MEASURES: Resident descriptive data (e.g., age, sex, education, and comorbidities), depression, agitation, resistiveness to care, and the quality of care interactions were obtained at baseline and 4 and 12 months. Treatment fidelity data included environment and policy assessments, performance of function focused care by staff, and service plan assessments. RESULTS: There was a significant positive treatment effect related to depression, agitation, resistiveness to care, and quality of care interactions with either less decline or some improvement in these behaviors and symptoms in the treatment versus control group. CONCLUSION: The study provides some statistical support, which may not necessarily be clinically significant evidence, for psychosocial outcomes of residents and care interactions between staff and residents in assisted living settings.

Pet Ownership Patterns and Successful Aging Outcomes in Community Dwelling Older Adults.

Introduction: Diminishing cognitive and physical functions, worsening psychological symptoms, and increased mortality risk and morbidity typically accompany aging. The aging population's health needs will continue to increase as the proportion of the population aged > 50 years increases. Pet ownership (PO) has been linked to better health outcomes in older adults, particularly those with chronic conditions. Much of the evidence is weak. Little is known about PO patterns as people age or the contribution of PO to successful aging in community-dwelling older adults. This study examines PO patterns among healthy community-dwelling older adults and the relationship of PO to cognitive and physical functions and psychological status. Methods: Participants in the Baltimore Longitudinal Study of Aging (> 50 years old, N = 378) completed a battery of cognitive, physical function, and psychological tests, as well as a PO questionnaire. Descriptive and non-parametric or general/generalized linear model analyses were conducted for separate outcomes. Results: Most participants (82%) had kept pets and 24% have pets: 14% dogs, 12% cats, 3% other pets. The most frequent reasons for having pets included enjoyment (80%) and companionship (66%). Most owners had kept the pet they had the longest for over 10 years (70%). PO was lower in older decades (p < 0.001). Pet owners were more likely to live in single-family homes and reside with others (p = 0.001) than non-owners. Controlling for age, PO was associated independently with better cognitive function (verbal leaning/memory p = 0.041), dog ownership predicted better physical function (daily energy expenditure, p = 0.018), and cat ownership predicted better cognitive functioning (verbal learning/memory, p = 0.035). Many older adults who did not own pets (37%) had regular contact with pets, which was also related to health outcomes. Conclusion: PO is lower at older ages, which mirrors the general pattern of poorer cognitive and physical function, and psychological status at older ages. PO and regular contact with pets (including PO) are associated with better cognitive status compared with those who did not own pets or had no regular contact with pets independent of age. Dog ownership was related to better physical function. Longitudinal analysis is required to evaluate the association of PO and/or regular contact with maintenance of health status over time.

Circadian activity rhythms and fatigue of adolescent cancer survivors and healthy controls: a pilot study.

STUDY OBJECTIVES: The primary objective of this study was to compare circadian activity rhythms (CARs) of adolescents within 5 years of completing cancer treatment (survivors) with that of healthy adolescent controls. Secondary objectives were to explore differences in the relationship of CARs and fatigue between survivors and controls and between early survivors (<12 months posttreatment) and late survivors (≥12 months posttreatment). METHODS: Twenty-nine survivors and 30 controls, aged 13-18 years, participated in this prospective, descriptive pilot study. Adolescents and their parents completed a baseline measure of adolescents' fatigue. Adolescents wore a wrist actigraph continuously for 7 days and concurrently kept a sleep diary. Activity data recorded by actigraphy were fitted to an extended cosine model to calculate six CAR variables: acrophase, amplitude, midline estimating statistic of rhythm (MESOR), up-MESOR, down-MESOR, and F-statistic. Linear mixed models explored the relationship between CARs and fatigue. RESULTS: There were no group differences on CAR or fatigue measures. Among survivors, earlier down-MESOR was associated with greater parent-reported fatigue (P = .020), and earlier acrophase (P = .023) and up-MESOR (P = .025) were associated with greater adolescent-reported fatigue. Significant CAR-by-time posttreatment interaction effects were found on fatigue between early and late survivors. Among controls, greater parent-reported fatigue was associated with greater MESOR (P = .0495). CONCLUSIONS: Survivors within the first 5 years posttreatment were similar to controls in CARs and fatigue, suggesting robust recovery of circadian rhythms posttreatment. Different CAR characteristics were associated with fatigue in survivors and controls. Time posttreatment influenced the relationship between CARs and fatigue for survivors, with significant effects only for early survivors.

Systematic Review and Meta-Analysis of the Effect of Nutrients on Blood Lead Levels in Pregnancy.

OBJECTIVE: To synthesize experimental and nonexperimental research on the relationship between nutrients and blood lead levels in pregnant women. We also performed a meta-analysis on a subgroup of studies on calcium and blood lead levels. DATA SOURCES: PubMed, Embase, and CINAHL databases were searched in July 2019. STUDY SELECTION: We included articles published in English in any year that reported the results of experimental or observational studies on the effect of nutrients on blood lead levels in pregnancy. DATA EXTRACTION: Three nurse reviewers extracted data and appraised the studies using tools from the Joanna Briggs Institute. DATA SYNTHESIS AND META-ANALYSIS: We included 28 studies from 16 countries. Study authors examined 14 distinct nutrients, with calcium being the most frequent. The metaregression included nine analyses of the effect of calcium on blood lead levels and showed a small but significant inverse relationship. The quality of evidence for the effect of calcium on lead levels was high. Eleven analyses were related to the effect of iron on blood lead levels. The quality of evidence was high, and we found mostly negative associations between iron intake and blood lead levels. The quality of evidence for the remaining nutrients was moderate, with few significant findings. CONCLUSION: Targeted nutritional interventions may be beneficial for pregnant women with current lead exposure or a history of elevated lead levels, particularly those with calcium- or iron-deficient diets. More rigorously designed studies are needed in this area.

Assessment of Parkinson disease quality measures on 12-month patient outcomes.

BACKGROUND: Quality measures (QMs) exist to operationalize guidelines by measuring adherence to guidelines through documentation, ultimately leading to improved patient outcomes. Studies are rare looking at the relationship between adherence to Parkinson disease (PD) QMs and patient outcomes. METHODS: We assessed adherence of our movement disorders specialists (MDSs) to the American Academy of Neurology's 2010 PD QM set through chart review using the measure set work group's criteria of documentation. We then evaluated patient outcomes to see whether there was a correlation with adherence to these QMs. RESULTS: Ninety-seven consecutive patients met the inclusion criteria. The mean disease duration was 9.3 (5.8) years. All patients were assessed by 1 of 4 MDSs. A total of 68% of QMs were documented across all patients. There was a small positive correlation between the number of documented QMs the year before the index visit and the number of calls/emails both the year before and after the index visit (r = 0.20, p = 0.04 and r = 0.26, p = 0.01, respectively.) There was a small negative correlation between the number of documented QMs and the number of PD follow-up visits the year after the index visit (r = -0.19, p = 0.05.) No other outcome showed a statistically significant correlation with the adherence to documented QMs. CONCLUSIONS: We found no clinically important improvement in patient outcomes with higher adherence levels. It is important that QM developers validate QMs to ensure that they fulfill the intended goal of improved patient outcomes.

Gender Differences and Other Factors Associated with Weight Gain Following Initiation of Infliximab: A Post Hoc Analysis of Clinical Trials.

BACKGROUND: In our clinical practice, women often report excess weight gain with infliximab (IFX) use. There are currently no studies investigating weight gain after antitumor necrosis factor therapy in patients with inflammatory bowel disease. The objective of this study was to evaluate the association of clinical factors, with a particular focus on sex and weight gain in patients with moderate to severe Crohn's disease (CD) or ulcerative colitis (UC) initiating IFX. METHODS: Data was extracted from ACCENT I, ACCENT II, ACT 1, and SONIC; included patients received IFX for induction or maintenance of remission of CD or UC. Patients treated with azathioprine (IFX 0 mg/kg) were included as controls. Baseline demographics, clinical characteristics, and weight at each follow-up for the study duration were collected. In addition to descriptive statistics, adjusted mixed effects models were used to test the association between clinical variables and weight gain. RESULTS: There were 1273 patients included for analysis; the majority was white (91%), with CD (81%), and half of patients (50%) were women. Upon univariate analysis, IFX dose, African American race, diagnosis of CD, elevated C-reactive protein, and low hematocrit and albumin were associated with weight gain (P < 0.001). Upon adjusted analysis, sex was significantly associated with weight gain (P = 0.009), with women experiencing a lower percentage increase from baseline weight than men (3.9% increase vs 4.3% increase). CONCLUSIONS: When starting IFX, those with markers of severe disease and with a diagnosis of CD are likely to gain more weight. Adjusting for confounding variables, women actually gain less weight than men after IFX treatment, although this difference is not clinically relevant.

Development of a systemic lupus erythematosus cardiovascular risk equation.

OBJECTIVE: Accelerated atherosclerosis remains the major cause of late death (after 5 years) in SLE. Yet, the 'traditional' cardiovascular risk equations (such as Framingham) consistently underestimate the risk. We sought to construct a data-driven formula for cardiovascular risk in SLE, based on data collected during the first year in a longitudinal cohort, for research purposes. METHODS: Two risk formulas were derived: one was for a broad set of cardiovascular outcomes (myocardial infarction, stroke, onset of angina, coronary procedures such as bypass or stent, claudication, peripheral artery disease or congestive heart failure); and the other for hard outcomes (myocardial infarction or stroke). Traditional and SLE-specific risk factors for cardiovascular disease were measured during the first year of cohort participation. Using Cox proportional hazards modelling, SLE formulas to calculate the 10-year risk of a subsequent cardiovascular event were derived and compared with the Framingham (for the broader outcome) and American College of Cardiology formulas (for the hard outcomes). RESULTS: SLE-related risk factors for each model included mean disease activity score (as measured by the SELENA revision of the SLE Disease Activity Index), low C3 and history of lupus anticoagulant. In those with SLE-related risk factors, the estimated 10-year risk based on our formula was substantially higher than the risk estimated based on the formulas for the general population. CONCLUSIONS: The excess cardiovascular risk among patients with SLE varies substantially depending on the SLE-related risk factors, age and traditional risk factors. Cardiovascular risk formulas based on individual data from patients with SLE may better estimate 10-year cardiovascular risk among patients with SLE than the Framingham or American College of Cardiology equations.

Sex differences in Parkinson's disease presentation and progression.

INTRODUCTION: Females have a reduced risk of Parkinson's disease (PD). However, it is unclear if sex is a prognostic factor. We aimed to examine differences in presentation, physician- and patient-reported PD outcomes, and progression by sex in a large clinical cohort. METHODS: This study was a secondary analysis of a cohort of PD patients seen at a tertiary care center. Sociodemographic and clinical characteristics, treatment, care timing, and outcomes were examined by sex. Sex differences in progression of impairment, disability, and health-related quality of life (HRQoL) were tested with five-year piecewise linear mixed-effects models. A mediation analysis assessed drivers of sex differences. RESULTS: The study included 914 males and 549 females. Females had significantly less social support, more psychological distress, and worse self-reported (but not physician-reported) disability and HRQoL at initial PD care visits, compared to males. Addressing anxiety symptoms may attenuate this difference. PD progression sex differences were minimal. CONCLUSION: PD progression does not differ by sex, yet patient-reported measures of disease severity are worse in females than males. To attenuate this sex difference in disease experience, psychological distress screening and management, particularly targeting females, should be implemented as part of PD clinical care.

Mobile Support for Older Adults and Their Caregivers: Dyad Usability Study.

BACKGROUND: Evaluation of digital health applications to support older adults' independence and family caregiving is needed. Digital health is increasingly providing opportunities for older adults and their family caregivers to educate, engage, and share health information across digital platforms. Few apps have documented evidence of usability by older adults and their caregivers. OBJECTIVE: The objective of this study was to determine the usability of a mobile app in a community-based older adult population aged ≥65 years. The app was designed to improve engagement of the patient-informal caregiver team. METHODS: This observational usability study was conducted in participants' homes and independent living facilities in Baltimore, Maryland. Community-dwelling older adults aged ≥65 years and their caregivers enrolled as a dyad (n=24, 12 dyads). The usability evaluation was a mobile and Web-based app that allowed older adult users to record social and health information and share this information with their caregivers. The older adult-caregiver dyad downloaded the app to a smart phone or accessed the Web version, participated in training and onboarding, and used the app for a 1-month period. Participants responded to weekly surveys sent by app push notifications and to the usability and satisfaction surveys at the end of the study. Participant satisfaction and usability were assessed using the Modified Mobile Application Rating Scale (M-MARS) and the System Usability Scale (SUS). RESULTS: The final sample comprised 16 people (8 dyads). Responses to the M-MARS were comparable between older adults and caregiver respondents in terms of engagement and functionality. Caregivers rated aesthetics slightly higher (mean 3.7) than older adult participants did (mean 3.3). Although most responses to the SUS were around the mean (2.3-3.4), older adults and their caregivers differed with regard to integration of app features (mean 3.7 vs 2.8) and the need to learn more before using the app (mean 2.3 vs 3.1). CONCLUSIONS: Technology ownership and use among older adults and caregivers was high. Usability and engagement of the mobile app was average. Additional training is recommended for older adults and their caregivers, including that on targeted behaviors for digital health record keeping.

Residual Disability, Mortality, and Nursing Home Placement After Hip Fracture Over 2 Decades.

OBJECTIVE: To examine trends in 12-month postfracture residual disability, nursing home placement, and mortality among patients with a hip fracture between 1990 and 2011. DESIGN: Secondary analysis of 12-month outcomes from 3 cohort studies and control arms of 2 randomized controlled trials. SETTING: Original studies were conducted as part of the Baltimore Hip Studies (BHS). PARTICIPANTS: Community-dwelling patients ≥65 years of age hospitalized for surgical repair of a nonpathologic hip fracture (N=988). MAIN OUTCOME MEASURES: Twelve-month residual disability, mortality, and nursing home residency were examined in case-mix adjusted models by sex and study. Residual disability was calculated by subtracting prefracture scores of Lower Extremity Physical Activities of Daily Living from scores at 12 months postfracture. We also examined the proportion of individuals with a 12-month score higher than their prefracture score (residual disability>0). RESULTS: Only small improvements were seen in residual disability between 1990 and 2011. No significant differences were seen for men between BHS2 (enrollment 1990-1991; mean residual disability=3.1 activities; 95% confidence interval [CI], 2.16-4.10) and BHS7 (enrollment 2006-2011; mean=3.1 activities; 95% CI, 2.41-3.82). In women, residual disability significantly improved from BHS2 (mean=3.5 activities; 95% CI, 2.95-3.99) to BHS3 (enrollment 1992-1995; mean=2.7 activities; 95% CI, 2.01-3.30) with no significant improvements in later studies. After adjustment, a substantial proportion (91% of men and 79% of women) had a negative outcome (residual disability, died, or nursing home residence at 12 months) in the most recently completed study (BHS7). CONCLUSIONS: Over 2 decades, patients undergoing usual care post-hip fracture still had substantial residual disability. Additional clinical and research efforts are needed to determine how to improve hip fracture treatment, rehabilitation, and subsequent outcomes.

An mHealth Diabetes Intervention for Glucose Control: Health Care Utilization Analysis.

BACKGROUND: Type 2 diabetes (T2D) is a major chronic condition requiring management through lifestyle changes and recommended health service visits. Mobile health (mHealth) is a promising tool to encourage self-management, but few studies have investigated the impact of mHealth on health care utilization. OBJECTIVE: The objective of this analysis was to determine the change in 2-year health service utilization and whether utilization explained a 1.9% absolute decrease in glycated hemoglobin (HbA1c) over 1-year in the Mobile Diabetes Intervention Study (MDIS). METHODS: We used commercial claims data from 2006 to 2010 linked to enrolled patients' medical chart data in 26 primary care practices in Maryland, USA. Secondary claims data analyses were available for 56% (92/163) of participants. In the primary MDIS study, physician practices were recruited and randomized to usual care and 1 of 3 increasingly complex interventions. Patients followed physician randomization assignment. The main variables in the analysis included health service utilization by type of service and change in HbA1c. The claims data was aggregated into 12 categories of utilization to assess change in 2-year health service usage, comparing rates of usage pre- and posttrial. We also examined whether utilization explained the 1.9% decrease in HbA1c over 1 year in the MDIS cluster randomized clinical trial. RESULTS: A significant group by time effect was observed in physician office visits, general practitioner visits, other outpatient services, prescription medications, and podiatrist visits. Physician office visits (P=.01) and general practitioner visits (P=.02) both decreased for all intervention groups during the study period, whereas prescription claims (P<.001) increased. The frequency of other outpatient services (P=.001) and podiatrist visits (P=.04) decreased for the control group and least complex intervention group but increased for the 2 most complex intervention groups. No significant effects of utilization were observed to explain the clinically significant change in HbA1c. CONCLUSIONS: Claims data analyses identified patterns of utilization relevant to mHealth interventions. Findings may encourage patients and health providers to discuss the utilization of treatment-recommended services, lab tests, and prescribed medications.
