Environmental drivers of increased ecosystem respiration in a warming tundra

Arctic and alpine tundra ecosystems are large reservoirs of organic carbon1,2. Climate warming may stimulate ecosystem respiration and release carbon into the atmosphere3,4. The magnitude and persistency of this stimulation and the environmental mechanisms that drive its variation remain uncertain5-7. This hampers the accuracy of global land carbon-climate feedback projections7,8. Here we synthesize 136 datasets from 56 open-top chamber in situ warming experiments located at 28 arctic and alpine tundra sites which have been running for less than 1 year up to 25 years. We show that a mean rise of 1.4 °C [confidence interval (CI) 0.9-2.0 °C] in air and 0.4 °C [CI 0.2-0.7 °C] in soil temperature results in an increase in growing season ecosystem respiration by 30% [CI 22-38%] (n = 136). Our findings indicate that the stimulation of ecosystem respiration was due to increases in both plant-related and microbial respiration (n = 9) and continued for at least 25 years (n = 136). The magnitude of the warming effects on respiration was driven by variation in warming-induced changes in local soil conditions, that is, changes in total nitrogen concentration and pH and by context-dependent spatial variation in these conditions, in particular total nitrogen concentration and the carbon:nitrogen ratio. Tundra sites with stronger nitrogen limitations and sites in which warming had stimulated plant and microbial nutrient turnover seemed particularly sensitive in their respiration response to warming. The results highlight the importance of local soil conditions and warming-induced changes therein for future climatic impacts on respiration.

A Process Evaluation of a Fall Prevention Intervention Using the RE-AIM Framework

BACKGROUND

Home hazard removal programs are effective in reducing falls among older adults, but delivery in the United States is limited.

OBJECTIVES

We completed a process evaluation of the Home Hazard Removal Program (HARP), an intervention delivered by occupational therapists.

METHODS

Using the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance), we examined outcomes using descriptive statistics and frequency distribution. We examined differences between covariates using Pearson correlation coefficients and two-sample t tests.

RESULTS

79.1% of eligible older adults participated (reach); they experienced a 38% reduction in fall rates (effectiveness). Ninety percent of recommended strategies were completed (adoption), 99% of intervention elements were delivered (implementation), and 91% of strategies were still used at 12 months (maintenance). Participants received an average of 258.6 minutes of occupational therapy. An average of US$765.83 was spent per participant to deliver the intervention.

CONCLUSIONS

HARP has good reach, effectiveness, adherence, implementation, and maintenance and is a low-cost intervention.

Examining the impact of a health report card on follow through with fall risk recommendations: an observational study

BACKGROUND

Increasing older adults' awareness of their personal fall risk factors may increase their engagement in fall prevention. The purpose of this study was to explore the impact of and participant satisfaction with a comprehensive occupational therapy fall risk screening and recommendations for evidence-based fall prevention strategies based on personalized fall risk results for community-dwelling older adults.

METHODS

Cognitively normal participants (Clinical Dementia Rating = 0) were recruited from an ongoing longitudinal study of memory and aging. Participants completed 2 annual in-home visits, fall risk questionnaires, and 12 months of fall monitoring between visits. Participants received a health report card with their fall risks and tailored recommendations in 6 domains. Participants completed follow-up questions at their next annual in-home visit about the fall risk recommendations and their satisfaction with receiving their fall risk results.

RESULTS

Two hundred five participants completed 2 annual visits and 12 months of fall monitoring. Of the 6 domains of recommendations provided, participants were most likely to follow through with getting an annual eye exam and reviewing their medications with their doctor or pharmacist. Older adults who fell were significantly more likely to receive recommendations for finding fall prevention classes (p = 0.01) and having a doctor or pharmacist review their medications (p = 0.004). The majority of participants were satisfied receiving their fall risk results (92%) and believed it to be beneficial (90%), though few participants shared their results with their doctor (20%).

CONCLUSIONS

An occupational therapy fall risk screening and tailored recommendations were not sufficient to encourage follow through with fall risk recommendations. Older adults may benefit from additional support and encouragement to reduce their fall risk. Additional research is needed to examine awareness of fall risks and follow through with fall risk recommendations among community-dwelling older adults.

Influence of falls, fall-related injuries, and fear of falling on social participation in people aging with long-term physical disability: a cross-sectional study

PURPOSE

This study examined prevalence and relationships among falls, injuries, fear of falling, and social participation in people aging with long-term physical disability (PAwLTPD).

MATERIALS AND METHODS

A convenience sample of 474 PAwLTPD recruited from community agencies and social media as baseline of a longitudinal cohort study. Inclusion criteria: 45-65 years, self-reported physical disability for ≥5 years, and English-speaking. Self-report surveys of physical/mental health, falls in the past year, fear of falling, and Patient-Reported Outcomes Measurement Information System (PROMIS) ability and satisfaction with participation in social roles and activities measures were collected.

RESULTS

Mean age 56.8 years; participants were mostly female (66.7%) and White (61.4%). Nearly 65% reported a fall; 56.6% of falls resulted in injury. Falls and fall-related injuries were associated with worse physical/mental health and presence of >5 health conditions. Seventy-five percent of participants reported fear of falling. Lower ability and satisfaction with participation were found in participants who fell and worried about falls.

CONCLUSIONS

PAwLTPD are at increased risk of falls, fall-related injuries, and fear of falling, which affects their ability to engage in social activities. Future research is needed to understand circumstances associated with falls and to develop effective interventions to address falls in PAwLTPD.

Aging with long-term physical disability: Cohort analysis of survey sample in the U.S

Background

Chronic health conditions, secondary conditions, and decreasing functional ability related to aging and/or changes in underlying impairment may influence participation for persons aging with long-term physical disability (AwD).

Objective

To examine sample integrity and baseline findings through exploration of associations of sociodemographic, health, and disability factors with social participation for persons AwD.

Methods

This is a longitudinal cohort study following persons AwD over three years, reporting baseline cohort study data. A convenience sample of 474 persons AwD aged 45-65 reporting physical disability of ≥5 years' duration was recruited through community organizations and social media. The cohort was majority female (66.7%) and single (62.0%), and over one-third (38.6%) was non-White. Pain, fatigue, depression, ability to participate in, and satisfaction with, social roles and activities were measured with the Patient Reported Outcomes Measurement Information System. Results were manually compared against AwD study samples identified through a focused literature review and national census data.

Results

Participants aged 55-60 and 61-65 had significantly lower rates of employment and marriage and higher rates of living alone than participants aged 45-54. Participants reported higher rates of fatigue, pain, and depression and lower ability to participate in, and satisfaction with, participation in, social roles and activities than the general population. Ability to participate and satisfaction with participation were highest among Black/African American participants.

Conclusions

Participants reported higher rates of common AwD symptoms and lower ability to participate and satisfaction with participation than the general population, consistent with prior studies of AwD samples. This cohort reflects the AwD population and can be considered an AwD sample, comparable to those found in existing literature. The focus of future analyses will be to gain a greater understanding of chronic health conditions, incidence of falls, engagement in everyday life activities, and the impact of the environment.

Efficacy, feasibility, and acceptability of in-home stroke education for stroke survivors

Barriers to learning after a stroke may prevent stroke survivors from acquiring helpful information regarding stroke prevention and preparedness. The objective of this study was to evaluate the efficacy, feasibility, and acceptability of a novel in-home stroke education program for survivors in the acute phase following a stroke. Study participants completed four in-home education sessions about stroke prevention and preparedness following their discharge home from inpatient rehabilitation. Sessions were designed to be completed within an 8-week period. Sessions were presented with evidence-based teaching methods and could be tailored to individual needs. Participants completed short quizzes before and after each education session to measure knowledge attainment. Forty-nine participants were included in this study. On average, the program was completed in 10 weeks, or 69.5 days (SD 29.6), and visits lasted 66.26 minutes; 81.5% of participants completed Visit 1, 77.5% completed Visit 2, and 73.5% completed Visits 3 and 4. Statistically significant changes from pretest-to-posttest scores were found for all races and genders and for ages 50-79. There was no significant change in pretest-to-posttest scores for participants over age 80 (n = 3). Results show that delivering a stroke education program can be accomplished, on an expanded timeline. The program was effective in increasing stroke knowledge for participants recently discharged from inpatient rehabilitation following a stroke.

Exploring the Perspectives of Adults Aging With Long-Term Physical Disabilities on Physical Activity: A Qualitative Study

BACKGROUND

Adults aging with long-term physical disabilities (AAwPD) face personal and environmental barriers to living independently, but little is known about their perspectives on and experiences with physical activity (PA).

PURPOSE

The purpose of this study was to explore the perspectives of AAwPD on PA.

RESEARCH DESIGN

Qualitative semi-structured interviews with AAwPD were conducted virtually via phone or videoconference.

STUDY SAMPLE

A convenience sample of AAwPD aged 45-65 and living with a physical disability for at least 5 years was recruited through aging organizations, disability organizations, and social media in St. Louis, Missouri until thematic saturation was reached (n = 20).

DATA COLLECTION AND ANALYSIS

Participants were asked semi-structured interview questions about their perspectives and experiences with PA following an interview guide developed by disability, aging, and qualitative research experts. Data were analyzed using text analysis in NVivo 12. Codes were developed into themes by the research team and validated using member checking methods.

RESULTS

Four themes emerged from the data: barriers and facilitators to engaging in PA, motivations and beliefs regarding PA, benefits of PA, and PA routines and habits. Participants reported a desire to engage in more PA but described barriers such as pain and fatigue symptoms, secondary health conditions, lack of social support, and fear of falling. Accessibility of facilities and equipment (eg, lack of ramps or equipment not at wheelchair height) and transportation barriers (eg, inconvenient schedules or excessive wait times) were specifically described as major environmental barriers.

CONCLUSION

Most participants' reported PA routines did not meet the quantity or intensity levels recommended by current guidelines. These results may help inform healthcare providers, community programs, and future interventions to improve PA levels for AAwPD, an underserved but growing demographic.

COVID-19: Factors Predicting Depressive Symptoms in People Aging With Long-Term Physical Disabilities

The mental health impact of the COVID-19 pandemic may be greater than that of the viral infection. This impact is likely greater for disadvantaged groups such as people with long-term physical disabilities (PwLTPD). This cross-sectional study used a multiple linear regression model to examine factors associated with depressive symptoms and to understand their relative importance during the onset of the COVID-19 pandemic. The model explained 58% of the variance in depressive symptoms. Anxiety was the most important predictor, accounting for 8% of variance. Higher levels of anxiety, loneliness, and financial stress; prior diagnosis of depression; and non-Black race predicted a higher level of depressive symptoms in PwLTPD during the onset of the COVID-19 pandemic. Occupational therapy practitioners should strategically acknowledge predictors of depression that cannot be modified and actively address those that can be modified through evidence-based interventions to improve depressive symptoms in PwLTPD.

Tailored medication management intervention delivered by occupational therapists for older adults: A study protocol

Introduction:

Medication management is an essential instrumental activity of daily living for older adults; however, 40–70% of older adults fail to take their medications correctly. Addressing medication management falls under the scope of occupational therapy, but there is a lack of evidence supporting occupational therapy interventions to improving medication management. This study’s primary aims are to examine the feasibility, acceptability, and preliminary efficacy of a Tailored Intervention for Medication Management delivered by occupational therapists to improve medication management.

Method/Design:

Single-blind, parallel-group randomized controlled equivalency trial, with two phases. Thirty community-dwelling older adults will be enrolled in this study. In Phase 1, participants in the treatment group will receive Tailored Intervention for Medication Management delivered remotely; those in the waitlist control will receive attention visits. In Phase 2, waitlist control participants will receive Tailored Intervention for Medication Management in person. The primary outcomes are feasibility and acceptability; secondary outcomes include preliminary efficacy of the intervention delivered by an occupational therapist remotely and in person. Additionally, the remote and in-person delivery methods will be compared to each other for equivalency.

Discussion:

Inability to manage medication and inappropriate polypharmacy are significant and prevalent problems that must be addressed so older adults can safely perform this essential instrumental activity of daily living.

Trial Registration:

ClinicalTrials.gov identifier NCT04717297.

Environmental interventions for preventing falls in older people living in the community

BACKGROUND

Falls and fall-related injuries are common. A third of community-dwelling people aged over 65 years fall each year. Falls can have serious consequences including restricting activity or institutionalisation. This review updates the previous evidence for environmental interventions in fall prevention.

OBJECTIVES

To assess the effects (benefits and harms) of environmental interventions (such as fall-hazard reduction, assistive technology, home modifications, and education) for preventing falls in older people living in the community.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, other databases, trial registers, and reference lists of systematic reviews to January 2021. We contacted researchers in the field to identify additional studies.

SELECTION CRITERIA

We included randomised controlled trials evaluating the effects of environmental interventions (such as reduction of fall hazards in the home, assistive devices) on falls in community-residing people aged 60 years and over.   DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Our primary outcome was rate of falls.

MAIN RESULTS

We included 22 studies from 10 countries involving 8463 community-residing older people. Participants were on average 78 years old, and 65% were women. For fall outcomes, five studies had high risk of bias and most studies had unclear risk of bias for one or more risk of bias domains. For other outcomes (e.g. fractures), most studies were at high risk of detection bias. We downgraded the certainty of the evidence for high risk of bias, imprecision, and/or inconsistency.  Home fall-hazard reduction (14 studies, 5830 participants) These interventions aim to reduce falls by assessing fall hazards and making environmental safety adaptations (e.g. non-slip strips on steps) or behavioural strategies (e.g. avoiding clutter).  Home fall-hazard interventions probably reduce the overall rate of falls by 26% (rate ratio (RaR) 0.74, 95% confidence interval (CI) 0.61 to 0.91; 12 studies, 5293 participants; moderate-certainty evidence); based on a control group risk of 1319 falls per 1000 people a year, this is 343 (95% CI 118 to 514) fewer falls. However, these interventions were more effective in people who are selected for higher risk of falling, with a reduction of 38% (RaR 0.62, 95% CI 0.56 to 0.70; 9 studies, 1513 participants; 702 (95% CI 554 to 812) fewer falls based on a control risk of 1847 falls per 1000 people; high-certainty evidence). We found no evidence of a reduction in rate of falls when people were not selected for fall risk (RaR 1.05, 95% CI 0.96 to 1.16; 6 studies, 3780 participants; high-certainty evidence). Findings were similar for the number of people experiencing one or more falls. These interventions probably reduce the overall risk by 11% (risk ratio (RR) 0.89, 95% CI 0.82 to 0.97; 12 studies, 5253 participants; moderate-certainty evidence); based on a risk of 519 per 1000 people per year, this is 57 (95% CI 15 to 93) fewer fallers. However, for people at higher risk of falling, we found a 26% decrease in risk (RR 0.74, 95% CI 0.65 to 0.85; 9 studies, 1473 participants), but no decrease for unselected populations (RR 0.99, 95% CI 0.92 to 1.07; 6 studies, 3780 participants) (high-certainty evidence). These interventions probably make little or no important difference to health-related quality of life (HRQoL) (standardised mean difference 0.09, 95% CI -0.10 to 0.27; 5 studies, 1848 participants; moderate-certainty evidence). They may make little or no difference to the risk of fall-related fractures (RR 1.00, 95% 0.98 to 1.02; 2 studies, 1668 participants), fall-related hospitalisations (RR 0.96, 95% CI 0.87 to 1.06; 3 studies, 325 participants), or in the rate of falls requiring medical attention (RaR 0.91, 95% CI 0.58 to 1.43; 3 studies, 946 participants) (low-certainty evidence). The evidence for number of fallers requiring medical attention was unclear (2 studies, 216 participants; very low-certainty evidence). Two studies reported no adverse events. Assistive technology Vision improvement interventions may make little or no difference to the rate of falls (RaR 1.12, 95% CI 0.84 to 1.50; 3 studies, 1489 participants) or people experiencing one or more falls (RR 1.09, 95% CI 0.79 to 1.50) (low-certainty evidence). We are unsure of the evidence for fall-related fractures (2 studies, 976 participants) and falls requiring medical attention (1 study, 276 participants) because the certainty of the evidence is very low. There may be little or no difference in HRQoL (mean difference 0.40, 95% CI -1.12 to 1.92) or adverse events (falls while switching glasses; RR 1.00, 95% CI 0.98 to 1.02) (1 study, 597 participants; low-certainty evidence). Results for other assistive technology - footwear and foot devices, and self-care and assistive devices (5 studies, 651 participants) - were not pooled due to the diversity of interventions and contexts.  Education  We are uncertain whether an education intervention to reduce home fall hazards reduces the rate of falls or the number of people experiencing one or more falls (1 study; very low-certainty evidence). These interventions may make little or no difference to the risk of fall-related fractures (RR 1.02, 95% CI 0.96 to 1.08; 1 study, 110 participants; low-certainty evidence).  Home modifications We found no trials of home modifications that measured falls as an outcome for task enablement and functional independence.

AUTHORS' CONCLUSIONS

We found high-certainty evidence that home fall-hazard interventions are effective in reducing the rate of falls and the number of fallers when targeted to people at higher risk of falling, such as having had a fall in the past year and recently hospitalised or needing support with daily activities. There was evidence of no effect when interventions were targeted to people not selected for risk of falling. Further research is needed to examine the impact of intervention components, the effect of awareness raising, and participant-interventionist engagement on decision-making and adherence.  Vision improvement interventions may or may not impact the rate of falls. Further research is needed to answer clinical questions such as whether people should be given advice or take additional precautions when changing eye prescriptions, or whether the intervention is more effective when targeting people at higher risk of falls. There was insufficient evidence to determine whether education interventions impact falls.

Interventions to promote independent participation among community-dwelling middle-aged adults with long-term physical disabilities: a systematic review

PURPOSE

People aging with long-term physical disabilities (PAwLTPD) are aging at an accelerated rate beginning in middle-age. They face age-related challenges in conjunction with their existing disabilities; thus, maintaining independence as they age is often difficult. The aim of this systematic review was to examine the effectiveness of rehabilitation interventions for middle-aged PAwLTPD to participate independently in the home and community.

MATERIALS AND METHODS

We searched four databases - MEDLINE, CINAHL, Web of Science, and EMBASE - for studies published from January 2005 to December 2020. Information from included studies was extracted using a critical appraisal form. Studies were categorized based on common themes, assigned level of evidence, and assessed for risk of bias.

RESULTS

Fourteen articles were included. Common themes derived were fall risk reduction, functional capacity, community mobility, and function within the home. The strongest evidence supports wheelchair skills training programs (WSTPs) among manual wheelchair users and targeted paretic limb exercise post-stroke. Moderate evidence supports exercise and multicomponent interventions for those with multiple sclerosis, adaptive strategy training and WSTPs to improve satisfaction with mobility for power wheelchair users, and home modifications/assistive technology for mobility-impaired individuals.

CONCLUSION

Interventions with strong and moderate evidence should be routinely offered for middle-aged PAwLTPD. Future research should focus on developing evidence-based interventions for middle-aged PAwLTPD.IMPLICATIONS FOR REHABILITATIONMiddle-aged PAwLTPD face the same aging-related challenges as people without disabilities but will experience additional difficulties due to compounding effects of long-term health conditions and aging.Current effective interventions to promote participation for middle-aged PAwLTPD have been measured over a wide range of outcomes, and many interventions should be used by clinicians on a case-by-case basis.Wheelchair skills training was found to have the strongest evidence and is recommended for use with middle-aged PAwLTPD who use manual and power wheelchairs.

World guidelines for falls prevention and management for older adults: a global initiative

BACKGROUND

falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. Current guidelines are inconsistent, with no up-to-date, globally applicable ones present.

OBJECTIVES

to create a set of evidence- and expert consensus-based falls prevention and management recommendations applicable to older adults for use by healthcare and other professionals that consider: (i) a person-centred approach that includes the perspectives of older adults with lived experience, caregivers and other stakeholders; (ii) gaps in previous guidelines; (iii) recent developments in e-health and (iv) implementation across locations with limited access to resources such as low- and middle-income countries.

METHODS

a steering committee and a worldwide multidisciplinary group of experts and stakeholders, including older adults, were assembled. Geriatrics and gerontological societies were represented. Using a modified Delphi process, recommendations from 11 topic-specific working groups (WGs), 10 ad-hoc WGs and a WG dealing with the perspectives of older adults were reviewed and refined. The final recommendations were determined by voting.

RECOMMENDATIONS

all older adults should be advised on falls prevention and physical activity. Opportunistic case finding for falls risk is recommended for community-dwelling older adults. Those considered at high risk should be offered a comprehensive multifactorial falls risk assessment with a view to co-design and implement personalised multidomain interventions. Other recommendations cover details of assessment and intervention components and combinations, and recommendations for specific settings and populations.

CONCLUSIONS

the core set of recommendations provided will require flexible implementation strategies that consider both local context and resources.

Association of a Perioperative Multicomponent Fall Prevention Intervention With Falls and Quality of Life After Elective Inpatient Surgical Procedures

IMPORTANCE

Falls after elective inpatient surgical procedures are common and have physical, emotional, and financial consequences. Close interactions between patients and health care teams before and after surgical procedures may offer opportunities to address modifiable risk factors associated with falls.

OBJECTIVE

To assess whether a multicomponent intervention that incorporates education, home medication review, and home safety assessment is associated with reductions in the incidence of falls after elective inpatient surgical procedures.

DESIGN, SETTING, AND PARTICIPANTS

This prospective propensity score-matched cohort study was a prespecified secondary analysis of data from the Electroencephalography Guidance of Anesthesia to Alleviate Geriatric Syndromes (ENGAGES) randomized clinical trial, which was conducted at a single academic medical center between January 16, 2015, and May 7, 2018. Patients in the intervention group of the present study were enrolled in either arm of the ENGAGES clinical trial. Patients in the control group were selected from the Systematic Assessment and Targeted Improvement of Services Following Yearly Surgical Outcomes Surveys prospective observational cohort study, which created a registry of patient-reported postoperative outcomes at the same single center. The propensity score-matched cohort in the present study included 1396 patients (698 pairs) selected from a pool of 2013 eligible patients. All patients underwent elective surgical procedures with general anesthesia and had a hospital stay of 2 or more days. Data were analyzed from January 2, 2020, to January 11, 2022.

INTERVENTIONS

The multicomponent safety intervention (offered to all patients in the ENGAGES clinical trial) included patient education on fall prevention techniques, home medication review by a geriatric psychiatrist (with communication of recommended changes to the surgeon), a self-administered home safety assessment, and targeted occupational therapy home visits with home hazard removal (offered to patients with a preoperative history of falls).

MAIN OUTCOMES AND MEASURES

The primary outcome was patient-reported falls within 1 year after an elective inpatient surgical procedure. The secondary outcome was quality of life 1 year after an elective surgical procedure, which was measured using the physical and mental composite summary scores on the Veterans RAND 12-item health survey (score range, 0-100 points, with 0 indicating lowest quality of life and 100 indicating highest quality of life).

RESULTS

Among 1396 patients, the median age was 69 years (IQR, 64-75 years), and 739 patients (52.9%) were male. With regard to race, 5 patients (0.4%) were Asian, 97 (6.9%) were Black or African American, 2 (0.1%) were Native Hawaiian or Pacific Islander, 1237 (88.6%) were White, 3 (0.2%) were of other race, and 52 (3.7%) were of unknown race; with regard to ethnicity, 12 patients (0.9%) were Hispanic or Latino, 1335 (95.6%) were non-Hispanic or non-Latino, and 49 (3.5%) were of unknown ethnicity. Adherence to individual intervention components was modest (from 22.9% for completion of the self-administered home safety assessment to 28.2% for implementation of the geriatric psychiatrist's recommended medication changes). Falls within 1 year after surgical procedures were reported by 228 of 698 patients (32.7%) in the intervention group and 225 of 698 patients (32.2%) in the control group. No significant difference was found in falls between the 2 groups (standardized risk difference, 0.4%; 95% CI, -4.5% to 5.3%). After adjusting for preoperative quality of life, patients in the intervention group had higher physical composite summary scores (3.8 points; 95% CI, 2.4-5.1 points) and higher mental composite summary scores (5.7 points; 95% CI, 4.7-6.7 points) at 1 year compared with patients in the control group.

CONCLUSIONS AND RELEVANCE

In this cohort study, a multicomponent safety intervention was not associated with reductions in falls within the first year after an elective surgical procedure; however, an increase in quality of life at 1 year was observed. These results suggest a need for other interventions, such as those designed to increase adherence, to lower the incidence of falls after surgical procedures.

Aging with long-term physical disability: Cohort analysis of survey sample in the U.S

Background: Chronic health conditions, secondary conditions, and decreasing functional ability related to aging and/or changes in underlying impairment may influence participation for persons aging with long-term physical disability (AwD). Objective: To examine sample integrity and baseline findings through exploration of associations of sociodemographic, health, and disability factors with social participation for persons AwD. Methods: This is a longitudinal cohort study following persons AwD over three years, reporting baseline cohort study data. A convenience sample of 474 persons AwD aged 45–65 reporting physical disability of ≥5 years’ duration was recruited through community organizations and social media. The cohort was majority female (66.7%) and single (62.0%), and over one-third (38.6%) was non-White. Pain, fatigue, depression, ability to participate in, and satisfaction with, social roles and activities were measured with the Patient Reported Outcomes Measurement Information System. Results: Participants aged 55–60 and 61–65 had significantly lower rates of employment and marriage and higher rates of living alone than participants aged 45–54. Participants reported higher rates of fatigue, pain, and depression and lower ability to participate in, and satisfaction with, participation in, social roles and activities than the general population. Ability to participate and satisfaction with participation were highest among Black/African American participants. Conclusions: Participants reported higher rates of common AwD symptoms and lower ability to participate and satisfaction with participation than the general population, consistent with prior studies of AwD samples. This cohort reflects the AwD population and can be considered an AwD sample, comparable to those found in existing literature. The focus of future analyses will be to gain a greater understanding of chronic health conditions, incidence of falls, engagement in everyday life activities, and the impact of the environment.

Factors influencing participation among adults aging with long-term physical disability

BACKGROUND

People aging with long-term physical disability (AwPD) experience barriers to participation and independent living. There are currently limited evidence-based interventions that address issues regarding participation for people AwPD.

OBJECTIVE

This study examined factors influencing participation in personal and life activities among people AwPD to inform future interventions.

METHODS

A cross-sectional study within an ongoing, community-based cohort study of participation was conducted. A purposive sample of people AwPD aged 45-65, living with a physical disability for at least five years, and who speak English was recruited through disability organizations, aging organizations, and social media. Participants answered open-ended questions about what supports they needed to successfully participate in nine activity categories derived from the Health and Retirement Study participation items (e.g., employment, community leisure). A content analysis was conducted using NVivo to categorize responses, and member checking occurred with four additional people AwPD.

RESULTS

A total of 215 participants completed the survey. Eight categories of factors emerged from the data: physical environment factors, social factors, symptoms, economic factors, policy factors, body structure and functions, mental and emotional state, and temporal factors. Participant responses illuminated a combination of environmental and individual factors. Physical effects of disability and accelerated aging, such as pain and fatigue, paired with environmental factors, such as accessibility of transportation, were reported as influencing participation.

CONCLUSIONS

People AwPD experience a range of factors that substantially impact their ability to remain independent and participate in society. By identifying barriers to participation, new interventions addressing these barriers may be developed, resulting in more effective service provision, enhanced participation in personal and life activities, and improved health and well-being.

A protocol for Removing Environmental Barriers to Independent Living (REBIL): An adapted evidence-based occupational therapy intervention to increase community participation for individuals aging with long-term physical disabilities

Background

People aging with long-term physical disabilities (PAwLTPD) are living longer and experiencing the challenges of aging, including the onset of secondary and age-related health conditions. PAwLTPD are at high risk of falls, fall injuries, diminished functional abilities, and compromised participation. However, no available programs support PAwLTPD to participate safely at home and in the community. The proposed study is to examine the feasibility and efficacy of an adapted intervention: Removing Environmental Barriers to Independent Living (REBIL).

Method/Design

A single-blinded randomized controlled trial (RCT) will be conducted. Participants who are 45-65 years old; self-report difficulty with ≥2 daily activities; have had a physical disability for ≥5 years; and live within 60 miles of the research lab are eligible. All participants will receive an initial in-home evaluation before randomization. The treatment group will receive REBIL (total five visits), which is tailored. The waitlist control group will be offered the same intervention after 6-month follow-up. Expected outcomes are high acceptability, fidelity, and adherence; low safety risk; improved community participation and daily activities performance; and fewer environmental barriers and fall hazards.

Discussion

Findings will serve as preliminary evidence for occupational therapy community practice. Outcomes will also inform future large, pragmatic trials.

Sociodemographic Differences in Respondent Preferences for Survey Formats: Sampling Bias and Potential Threats to External Validity

Objective

To explore sampling bias as a result of survey format selection by examining associations between characteristics of people aging with long-term physical disability (PAwLTPD) and their preferences for phone or web-based survey format.

Design

A cross-sectional study using a secondary data analysis approach.

Setting

Data were from an ongoing longitudinal cohort study conducted in the community.

Participants

Convenience sampling was used. PAwLTPD who participated in year 2 of the longitudinal cohort study were included. Inclusion criteria were age 45-65 years, English speaking, and self-reported onset of a physical disability at least 5 years prior to study recruitment. Two participants completed the survey using both phone and web formats and were thus excluded; 387 participants (N=387) were included in the analysis.

Interventions

Not applicable.

Main Outcome Measures

Choice of survey format and demographics (age, sex, race and ethnicity, marital status, living arrangement, socioeconomic status) were collected in addition to self-rated physical health.

Results

Participants were on average 58.2±5.6 years old. A total of 33% were male, and 62% were White. Approximately 40% of participants completed phone surveys. The phone survey group was significantly older (t=−4.76, P<.001) and had lower education (U=11133, z=−6.65, P<.001) and lower self-rated physical health (U=15420, z=−2.38, P=.017) than the web survey group. Participants who were White (χ²=60.69; df=1; P<.001; odds ratio [OR], 0.18) or were in a long-term relationship were less likely to choose phone surveys (χ²=42.20; df=1; P<.001; OR, 0.21). Those who earned $10,008 or less annually (χ²=53.90; df=1; P<.001; OR, 5.22) or who lived alone (χ²=36.26; df=1; P<.001; OR, 3.64) were more likely to choose phone surveys. Participants with paid work (χ²=16.81, df=1, P<.001) tended to select web-based surveys, while those on disability leave (χ²=9.61, df=1, P<.01) were more likely to choose phone surveys.

Conclusions

Sociodemographics are associated with survey format choice in PAwLTPD. Findings largely support the existing understanding of digital literacy but also provide insight into the potential occurrence of sampling bias when multiple survey format options are not offered. These findings have implications for investigators who aim to reach a more representative sample of people with disabilities.

Feasibility of an Automated Bidet Intervention to Decrease Caregiver Burden

IMPORTANCE

Informal caregivers often receive limited training and support, especially in providing assistance with toileting, a physically and emotionally demanding activity of daily living. This increases caregivers' risk for physical injury and burnout and jeopardizes older adults' ability to age in place.

OBJECTIVE

To assess the feasibility, acceptability, and preliminary efficacy of a toileting intervention using an automated bidet to reduce the amount of physical assistance required from caregivers.

DESIGN

Randomized wait-list control feasibility study.

SETTING

Caregiver's home.

PARTICIPANTS

Ten informal caregivers.

INTERVENTION

An occupational therapy intervention to educate and train caregiving dyads to use an automated bidet system. Outcomes and Measures: Feasibility was measured in terms of recruitment and retention, bidet installation, ability to operate the bidet, acceptability (a process evaluation), preliminary efficacy (physical barriers and impact on caregiver outcomes of performance, satisfaction, and self-efficacy), and adverse events.

RESULTS

All bidets were installed successfully. All caregivers reported that the intervention made toileting easier and increased their confidence. Physical barriers decreased for the treatment group. The bidet had a large effect on self-efficacy for the treatment group.

CONCLUSIONS AND RELEVANCE

The results suggest that the automated bidet intervention is feasible and acceptable and can have a positive impact on caregiver outcomes when assisting with toileting. What This Article Adds: A toileting intervention using an automated bidet is feasible and acceptable for caregivers of older adults and can reduce the amount of physical assistance required from caregivers.

Home Hazard Removal to Reduce Falls Among Community-Dwelling Older Adults: A Randomized Clinical Trial

IMPORTANCE

Falls are the leading preventable cause of morbidity, mortality, and premature institutionalization for community-dwelling older adults.

OBJECTIVE

To test the effectiveness of a behavioral intervention on fall risk among older adults receiving services from an Area Agency on Aging.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial examined a home hazard removal intervention in the community using a race- and sex-stratified randomization design. Older adults receiving services from the Area Agency on Aging in urban St Louis, Missouri, were assigned to a home hazard removal intervention delivered over 2 weeks with a 6-month booster or usual care control. Eligible participants were adults aged 65 years or older who did not have dementia, were at high risk for falling, and resided in the community. Enrollment occurred from January 2015 to September 2016; 12-month follow-up occurred from February 2016 to October 2017. Data were analyzed from February 2019 to July 2021.

INTERVENTIONS

The intervention was a home hazard removal program delivered by an occupational therapist in the home that included a comprehensive clinical assessment and a tailored hazard removal plan. Usual care control consisted of annual assessments and community referral.

MAIN OUTCOMES AND MEASURES

The primary outcome was the hazard of a fall over 12 months. Prespecified secondary outcomes included the rate of falls over 12 months, daily activity performance, falls self-efficacy, and self-reported quality of life.

RESULTS

A total of 310 participants (mean [SD] age, 75 [7.4] years; 229 [74%] women; 161 Black participants [52%]) were randomized, with 155 participants assigned to the intervention and 155 participants assigned to usual care. Retention was 127 participants (82%) in the intervention group and 126 participants (81%) in the control group. There was no difference for our primary outcome of fall hazard (hazard ratio, 0.90; 95% CI, 0.66-1.27). There was a 38% reduction in the rate of falling in the intervention group compared with the control group (relative risk, 0.62; 95% CI, 0.40-0.95; P = .03). At 12 months, the rate of falls per person-year was 1.5 (95% CI, 1.32-1.75) in the intervention group and 2.3 (95% CI, 2.08-2.60) in the control group. There was no difference in daily activity performance (adjusted difference, -0.20; 95% CI, -0.95 to 0.55; P = .60), falls self-efficacy (adjusted difference, -0.12; 95% CI, -1.25 to 1.01; P = .84), or quality of life (adjusted difference, 0.84; 95% CI, -0.95 to 2.64; P = .35).

CONCLUSIONS AND RELEVANCE

This randomized clinical trial found that a brief home hazard removal program did not reduce the hazard of falls among community-dwelling older adults at high risk for falling. The intervention was effective in achieving a reduced rate of falls, a prespecified secondary outcome. This effectiveness study has the potential for delivery through the national aging services network.

Evaluation of Race as a Predictor of Fear of Falling in Black Older Adults

Fear of falling (FOF) is a common issue and health concern reported by adults 65 years of age and older.There is mixed evidence about potential disparity in fall incident rates due to race and FOF, and it is unclear if and under what circumstance falls rates and risks differ by racial ethnicity. The purpose of this study is to determine if race predicts fear of falling in older adults at greater risk for falls; and to examine the relationship between activities of daily living (ADL) and mobility performance measures with FOF. A cross-sectional observational study was used to examine predictors of FOF among community dwelling-older adults using data from two longitudinal randomized clinical trials (RCT). Participants (N=259) had a mean age of 75.7 ±7.4, 78.8% female, 80.64% Black, and 77.03% White or Other, with ≥ 1 fall in the last 12 months. Subjects completed a demographic profile; the Tinetti and Short Falls Efficacy Scale to assess FOF; and activities of daily living (ADL) and mobility performance scales to assess function. The chi square analysis revealed Black older adults were two times more likely to report FOF (OR = 2.17, 95% CI = 1.14, 4.15; p=.05) in comparison to White older adults. The regression analysis demonstrated that race is a significant factor to predict FOF (OR = .67, 95% CI = 1.21, 3.24; p=.05); and the descriptive analysis revealed significantly worse ADL and mobility function scores within the high FOF group.

Underrepresentation of Adults and Older Adults With Disabilities in Behavioral Clinical Trials: A Scoping Review

A lack of evidence-based interventions for people aging with long-term physical disabilities exists. To examine the exclusion of people with disabilities in behavioral clinical trials, a scoping review was conducted. ClinicalTrials.gov was searched for interventional behavioral studies from the United States completed from 2008–2018, with results focused on adults (18–64) and older adults (65+). In total, 158 clinical trials were included. In 129 articles, health conditions were excluded 697 times. Seventy-one clinical trials excluded at least one health condition with strong justification, 11 with poor justification, and 115 without justification. There is strong evidence that people with disabilities are excluded from behavioral clinical trials, often without justification. To help close this gap, our presentation will discuss how translational research strategies, focused on adapting existing EB behavioral trials, can be used to increase the availability of interventions that address the needs of individuals aging with and into long-term disabilities.

Longitudinal Impact of an Interdisciplinary Course on Aging for First-Year Students

Undergraduate courses on aging have the potential to counteract negative stereotypes about older adults and to shift students’ academic plans as they learn about aging-related opportunities. For six years we have taught an interdisciplinary course on aging for first-year undergraduate students. We present longitudinal data on students’ attitudes and academic trajectories after taking the course. Students who took the course (n = 314) and comparable students who were not in the course (n = 353) were surveyed prior to and at the end of their first semester and at the end of each subsequent academic year. At each time point students rated the degree to which aging issues are relevant to their personal and professional lives. Students also reported aging-related curricular and extracurricular activities they pursued. Multivariate repeated-measures analyses revealed a significant interaction such that personal and professional relevance of aging issues were lower and remained stable for students not in the class, and were higher and increased for students in the class, F(2,226) = 13.18, F(2,226) = 14.94, p’s < .01. However, for course students, relevance returned to baseline levels by the end of their first year and remained constant in subsequent years. Results from chi-square analyses revealed that students in the class reported more engagement in aging-related courses, χ2(1) = 8.3, research projects, χ2(1) = 90.1, and extracurriculars, χ2(2) = 20.6, p’s < .01. Results suggest that exposing students to information about aging early has the potential to alter academic trajectories, highlighting the importance of early education.

Perspective on the "African American participation in Alzheimer disease research: Effective strategies" workshop, 2018

The Washington University School of Medicine Knight Alzheimer Disease Research Center's "African American Participation in Alzheimer Disease Research: Effective Strategies" Workshop convened to address a major limitation of the ongoing scientific progress regarding Alzheimer's disease and related dementias (ADRD): participants in most ADRD research programs overwhelmingly have been limited to non-Hispanic white persons, thus precluding knowledge as to how ADRD may be represented in non-white individuals. Factors that may contribute to successful recruitment and retention of African Americans into ADRD research were discussed and organized into actionable next steps as described within this report.

Preoperative Cognitive Abnormality, Intraoperative Electroencephalogram Suppression, and Postoperative Delirium: A Mediation Analysis

BACKGROUND

Postoperative delirium is a common complication that hinders recovery after surgery. Intraoperative electroencephalogram suppression has been linked to postoperative delirium, but it is unknown if this relationship is causal or if electroencephalogram suppression is merely a marker of underlying cognitive abnormalities. The hypothesis of this study was that intraoperative electroencephalogram suppression mediates a nonzero portion of the effect between preoperative abnormal cognition and postoperative delirium.

METHODS

This is a prespecified secondary analysis of the Electroencephalography Guidance of Anesthesia to Alleviate Geriatric Syndromes (ENGAGES) randomized trial, which enrolled patients age 60 yr or older undergoing surgery with general anesthesia at a single academic medical center between January 2015 and May 2018. Patients were randomized to electroencephalogram-guided anesthesia or usual care. Preoperative abnormal cognition was defined as a composite of previous delirium, Short Blessed Test cognitive score greater than 4 points, or Eight Item Interview to Differentiate Aging and Dementia score greater than 1 point. Duration of intraoperative electroencephalogram suppression was defined as number of minutes with suppression ratio greater than 1%. Postoperative delirium was detected via Confusion Assessment Method or chart review on postoperative days 1 to 5.

RESULTS

Among 1,113 patients, 430 patients showed evidence of preoperative abnormal cognition. These patients had an increased incidence of postoperative delirium (151 of 430 [35%] vs.123 of 683 [18%], P < 0.001). Of this 17.2% total effect size (99.5% CI, 9.3 to 25.1%), an absolute 2.4% (99.5% CI, 0.6 to 4.8%) was an indirect effect mediated by electroencephalogram suppression, while an absolute 14.8% (99.5% CI, 7.2 to 22.5%) was a direct effect of preoperative abnormal cognition. Randomization to electroencephalogram-guided anesthesia did not change the mediated effect size (P = 0.078 for moderation).

CONCLUSIONS

A small portion of the total effect of preoperative abnormal cognition on postoperative delirium was mediated by electroencephalogram suppression. Study precision was too low to determine if the intervention changed the mediated effect.

A scoping review of fall hazards in the homes of older adults and development of a framework for assessment and intervention

INTRODUCTION

Comprehensive evaluation and intervention provided by occupational therapists is effective in reducing the presence of fall hazards in the homes of older adults. The purpose of this study was to document known environmental hazards and to update a previous content analysis. A secondary goal reviewed a framework for evaluation and practice.

METHODS

A comprehensive scoping review of published academic articles was performed from 1996 to 2019 to answer: What environmental hazards have been associated with falls in the homes of community-dwelling older adults? Data was extracted in a standardised critical appraisal worksheet and content analysis was conducted. A review of a conceptual framework for assessment and intervention was conducted by international experts (n = 6) in face-to-face interviews.

RESULTS

Fourteen studies met the inclusion criteria for the scoping study. The studies reported 17 in-home environmental hazards: throw rugs/carpets, clutter, cords/wires, poorly placed light switches, items placed too low, items placed too high, no grab bars, toilet seats too low, uneven floor surfaces, slippery/wet surfaces, snowy/icy surfaces, backless/unsupportive shoes, unsteady stairs, inadequate lighting, inadequate heating/cooling, step stools without railings, and pets.

CONCLUSION

A comprehensive list of specific fall hazards in and around the homes of older adults and a guiding framework offers occupational therapists an evidence-based foundation for fall prevention efforts.

Examination of Community Participation of Adults With Disabilities: Comparing Age and Disability Onset

Objective: Explore community participation between adults with disabilities ⩽50 and >50 years and between early-(⩽40) and late-(>40) onset disability. Method: A survey examining participation was conducted with a national convenience sample of 692 community-dwelling adults with disabilities. Results: Participants ⩽50 reported presence of more (p < .05) environmental supports for work/volunteer/education and use of transportation. Participants >50 had higher (p < .01) visits to pharmacies; higher (p < .05) evaluative quality of participation (EQOP) at gas stations, exercise facilities, beauty salons/barbers, and use of transportation (p < .01); and more difficulty participating without assistance at grocery stores (p < .05) and gas stations (p < .01). The early-onset group reported higher (p < .05) EQOP at work/volunteer/education and homes of family/friends. The late-onset group reported higher (p < .01) EQOP at exercise facilities; more (p < .05) environmental supports at pharmacies, restaurants, grocery stores (p < .01), doctors' offices (p ⩽ .01), and beauty salons/barbers (p < .01); greater (p < .01) influence of pain/fatigue; and more difficulty without assistance at grocery stores (p < .05) and gas stations (p < .01). Discussion: Understanding these differences can improve interventions to support community participation of individuals aging with disabilities.

Evidence to Improve Physical Activity among Medically Underserved Older adults: A Scoping Review

BACKGROUND AND OBJECTIVES

Participation in leisure physical activity (PA) and engagement in PA interventions among older adults is influenced by socioeconomic status (SES), race/ethnicity, and environment. However, studies of PA for medically underserved older adults have not yet been systematically evaluated. The objective of this study is to map the nature and extent of research conducted on PA participation, interventions, and components of effective leisure PA programs for medically underserved older adults.

RESEARCH DESIGN AND METHODS

The five-stage approach was used to conduct this scoping review. We searched PubMed, CINAHL, and Cochrane Library for peer-reviewed studies published between 2006 and 2016. Data extracted from selected studies included study population, study type, purpose of intent, evidence level, barriers to PA participation, and components of PA intervention.

RESULTS

Three hundred and ninety-two articles were identified, and 60 studies were included in the final data charting. Existing literature showed that most studies remained descriptive in nature, and few intervention studies have achieved a high level of evidence. Among 21 intervention studies, only 4 were explicitly conducted for older adults. Culturally adapted materials, race/ethnicity-specific barriers and facilitators, and form of intervention were important components for intervention programs.

DISCUSSION AND IMPLICATIONS

Findings indicate that more studies are needed to reduce health disparities related to PA participation for medically underserved older adults. Intervention components such as race/ethnicity-relevant barriers and facilitators and culturally sensitive materials are also needed for PA interventions targeting underserved older adults in order to provide evidence for best practices.

INNOVATIONS IN HOME MODIFICATION RESEARCH: THE STATE OF THE ART

The overwhelming preference of older adults is to stay in their homes for as long as possible (AARP). However, most housing lacks supportive features and presents barriers that jeopardize residents’ ability to successfully age in place. Only 1% of houses have five key features to ensure accessibility: no-step entry, single-floor living, lever door handles, accessible electrical controls, and extra-wide doors and hallways (Harvard Joint Center for Housing Studies), making the vast majority unsuitable for persons who use wheelchairs and problematic for the growing number of people with activity limitations. Persons least likely to have such features in their homes need them the most: old-old, low income, frail, and residents in older housing stock. Although home modification can support people as their needs change and preclude the need to move, often to institutional settings, the majority of older adults lack these supports. Recent studies have demonstrated the role of home modification in health, safety, and cost effectiveness. This symposium will convene a panel of researchers to share evidence-base in home modification, recent cost-saving innovations including the CAPABLE Program, and policy change to improve service delivery.

Effect of a Novel Transition Program on Disability After Stroke: A Trial Protocol

IMPORTANCE

A gap in care for stroke survivors exists at the point of transition from inpatient rehabilitation to home, when survivors encounter new environmental barriers because of the cognitive and sensorimotor sequelae of stroke. Resolving these barriers and improving independence in the community have the potential to significantly improve stroke survivors' long-term morbidity.

OBJECTIVE

To investigate the efficacy and safety of a novel enhanced rehabilitation transition program to reduce environmental barriers and improve daily activity performance and community participation among stroke survivors.

DESIGN, SETTING, AND PARTICIPANTS

This is a phase 2b, single-blind, parallel-group, randomized clinical trial. Participants will be randomized using a 1:1 allocation ratio, stratified by Functional Independence Measure and age, to either attentional control or the intervention. Community Participation Transition After Stroke (COMPASS) is a complex intervention that uses 2 complementary evidence-based interventions: home modifications and strategy training delivered in the home. Community participation after stroke, measured by the Reintegration to Normal Living Index, is the primary outcome. Secondary outcomes include quality of life after stroke, measured by the Stroke Impact Scale, and daily activity performance and magnitude of environmental barriers in the home, both measured by the In-Home Occupational Performance Evaluation. An intention-to-treat analysis will be used. A total of 180 participants, who are 50 years or older, were independent in activities of daily living prior to stroke, and are undergoing inpatient rehabilitation following stroke with a plan to be discharged home, will be included in the study.

DISCUSSION

Stroke is a leading cause of serious long-term disability in the United States. The COMPASS study is ongoing. To date, 99 participants have been recruited and 77 randomized, with 37 in the treatment group and 40 in the control group. Resumption of previous activities immediately after discharge can improve immediate and long-term community participation. Results from this study will fill a critical gap in stroke rehabilitation evidence by providing important information about the long-term community participation and daily activity performance among stroke survivors as well as environmental barriers in their homes.

Achieving Milestones as a Prerequisite for Proceeding With a Clinical Trial

BACKGROUND

Although the National Institutes of Health (NIH) invests $30 billion in research annually, many funded studies fail to generate results that can inform practice. The National Institutes of Health introduced a phased funding mechanism as one potential solution. Study-specific milestones are established for an initial pilot phase. We assess the utility of this phased approach through the ongoing Electroencephalography (EEG) Guidance of Anesthesia to Alleviate Geriatric Syndromes (ENGAGES) pragmatic clinical trial. The hypothesis of the trial is that EEG guidance of general anesthesia, through prevention of EEG suppression, can decrease postoperative delirium and its downstream negative sequelae.

METHODS

In collaboration with study stakeholders, we identified critical milestones for the ENGAGES study, with themes common to many clinical trials. These themes include: regulatory tasks; enrollment targets; feasibility and impact of study intervention; primary outcome incidence; measurement reliability of primary outcome; and follow-up. Progress in achieving the milestones was assessed at regular intervals during the pilot phase by ENGAGES investigators, a National Institute on Aging program officer, and a nonpartisan research organization (Westat).

RESULTS

Regulatory tasks, including institutional review board approval, infrastructure establishment, and trial registration, were completed on schedule. A total of 117 patients were randomized, exceeding the target by 51. The EEG-guided protocol was successfully implemented, and a relevant effect on anesthetic practice was demonstrated (decrease in median age-adjusted minimum alveolar anesthetic concentration from 0.93 to 0.78 [P < .001] and increase in median proportion of zero EEG suppression time from 87% to 94% [P < .01]). Nearly all patients (115 of 117, 98.3%) were assessed for delirium using the Confusion Assessment Method, and the delirium incidence was similar (28.1%; 95% CI, 20%-37%) to the estimate (25%) used for the sample size calculation. Good interrater reliability of delirium assessment was demonstrated (κ = 0.94 [95% CI, 0.86-1]). Finally, 1-month follow-up vital status data were obtained for 96.9% of patients, with 85.7% of patients completing at least 1 survey.

CONCLUSIONS

With the ENGAGES trial, we demonstrated that key milestones can be identified and progressively assessed during a pilot phase. Success in attaining appropriate milestones hypothetically predicts meaningful completion of a study, and can provide justification for proceeding beyond a pilot phase. The impact of this phased approach on return on investment and scientific yield requires additional study.

Scoring, Clinical Utility, and Psychometric Properties of the In-Home Medication Management Performance Evaluation (HOME-Rx)

IMPORTANCE

Forty percent to 75% of community-dwelling older adults are not able to adhere to their medication routine. A medication management assessment can correctly identify the reasons for nonadherence and the barriers contributing to it.

OBJECTIVE

To further develop the HOME-Rx, an in-home medication management assessment, by modifying scoring metrics, improving clinical utility, and establishing psychometric properties.

DESIGN

In Phase 1, the scoring metrics were modified, and the clinical procedures were evaluated. In Phase 2, the psychometric properties were established.

SETTING

The homes of older adults.

PARTICIPANTS

Older adults who took three or more medications, managed their own medications, and lived in their own home were eligible. Older adults with cognitive impairment were ineligible.

OUTCOMES AND MEASURES

We assessed concurrent validity with the Performance Assessment for Self-Care Skills (PASS) and Medication Management Instrument for Deficiencies in the Elderly (MedMaIDE) and established interrater reliability.

RESULTS

The PASS was positively correlated with the HOME-Rx Performance and Safety subscales; the MedMaIDE was negatively correlated with the HOME-Rx Performance subscale and positively correlated with the Barriers subscale. Interrater reliability was excellent (ICCs = .87-1.00).

CONCLUSIONS AND RELEVANCE

All relationships were as predicted: The HOME-Rx is a valid and reliable performance-based assessment that provides clinicians and researchers with a measure of older adults' actual medication management ability in the home using their medications. The results can potentially be used to guide treatment planning and improve medication management.

WHAT THIS ARTICLE ADDS

Occupational therapy practitioners can use the HOME-Rx to adequately determine performance problems, safety concerns, and environmental barriers and potentially to guide treatment planning and improve medication management for older adults.

Environmental interventions for preventing falls in older people living in the community

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To assess the effects (benefits and harms) of environmental interventions (such as assistive devices, and reduction of fall hazards in home, outdoors, and public places) for preventing falls in older people living in the community.

Effect of Electroencephalography-Guided Anesthetic Administration on Postoperative Delirium Among Older Adults Undergoing Major Surgery: The ENGAGES Randomized Clinical Trial

IMPORTANCE

Intraoperative electroencephalogram (EEG) waveform suppression, often suggesting excessive general anesthesia, has been associated with postoperative delirium.

OBJECTIVE

To assess whether EEG-guided anesthetic administration decreases the incidence of postoperative delirium.

DESIGN, SETTING, AND PARTICIPANTS

Randomized clinical trial of 1232 adults aged 60 years and older undergoing major surgery and receiving general anesthesia at Barnes-Jewish Hospital in St Louis. Recruitment was from January 2015 to May 2018, with follow-up until July 2018.

INTERVENTIONS

Patients were randomized 1:1 (stratified by cardiac vs noncardiac surgery and positive vs negative recent fall history) to receive EEG-guided anesthetic administration (n = 614) or usual anesthetic care (n = 618).

MAIN OUTCOMES AND MEASURES

The primary outcome was incident delirium during postoperative days 1 through 5. Intraoperative measures included anesthetic concentration, EEG suppression, and hypotension. Adverse events included undesirable intraoperative movement, intraoperative awareness with recall, postoperative nausea and vomiting, medical complications, and death.

RESULTS

Of the 1232 randomized patients (median age, 69 years [range, 60 to 95]; 563 women [45.7%]), 1213 (98.5%) were assessed for the primary outcome. Delirium during postoperative days 1 to 5 occurred in 157 of 604 patients (26.0%) in the guided group and 140 of 609 patients (23.0%) in the usual care group (difference, 3.0% [95% CI, -2.0% to 8.0%]; P = .22). Median end-tidal volatile anesthetic concentration was significantly lower in the guided group than the usual care group (0.69 vs 0.80 minimum alveolar concentration; difference, -0.11 [95% CI, -0.13 to -0.10), and median cumulative time with EEG suppression was significantly less (7 vs 13 minutes; difference, -6.0 [95% CI, -9.9 to -2.1]). There was no significant difference between groups in the median cumulative time with mean arterial pressure below 60 mm Hg (7 vs 7 minutes; difference, 0.0 [95% CI, -1.7 to 1.7]). Undesirable movement occurred in 137 patients (22.3%) in the guided and 95 (15.4%) in the usual care group. No patients reported intraoperative awareness. Postoperative nausea and vomiting was reported in 48 patients (7.8%) in the guided and 55 patients (8.9%) in the usual care group. Serious adverse events were reported in 124 patients (20.2%) in the guided and 130 (21.0%) in the usual care group. Within 30 days of surgery, 4 patients (0.65%) in the guided group and 19 (3.07%) in the usual care group died.

CONCLUSIONS AND RELEVANCE

Among older adults undergoing major surgery, EEG-guided anesthetic administration, compared with usual care, did not decrease the incidence of postoperative delirium. This finding does not support the use of EEG-guided anesthetic administration for this indication.
