Recruitment of older adults from long-term care settings for a longitudinal clinical trial

Recruitment of residents for research from long-term care settings is known to be difficult. The purpose of this study was to summarize the effectiveness and cost in terms of time and dollars of recruitment methods for a cluster-randomized controlled clinical trial conducted in long-term care settings. This study was a retrospective, exploratory, descriptive analysis of recruitment data. After recruitment of 15 independent and assisted living communities, residents at each site were recruited to participate in the study using combinations of 12 different recruitment methods. Recruitment methods, time spent screening, and enrollment data were collected. Recruitment data were analyzed at the levels of site, research staff member, and participant. Over the study period, 279 older adults were screened and 172 enrolled from the 15 sites. Many participants were cognitively impaired. Research staff spent 39-89 h recruiting at each site and utilized an average of four different recruitment methods per site. Introductions of participants by site contacts yielded the most consented participants compared to other recruitment methods. Sites that had a dedicated recruiter utilized more recruiting methods and enrolled more participants than those without a dedicated recruiter. The cost of recruiting averaged $1490 per site and $93-$258 per enrollee (mean $144, standard deviation $58), but was more costly in larger facilities. Recruitment of older adults from long-term care communities requires multiple methods of recruitment, skilled recruitment staff, and trust with the staff and potential participants.

Influence of Risk Factors on the Well-Being of Elderly Women with Knee Osteoarthritis

Background and Objectives: Knee osteoarthritis (KOA) is a widespread chronic joint disease characterized by functional limitations and pain. Functioning restrictions exert a detrimental impact on societal integration, relationships, and psychological well-being, resulting in significant emotional distress in KOA patients. The objective of this study is to examine how various risk factors impact the emotional well-being of individuals with KOA. Materials and Methods: This prospective cross-sectional study involved 154 postmenopausal women treated at the Special Hospital for Rheumatic Diseases in Novi Sad, Serbia. The experimental group comprised 97 individuals with chronic knee pain and structural knee damage (Kellgren-Lawrence (KL) scale II-IV), while the control group had 53 individuals with chronic knee pain but no structural knee damage (KL scale 0-I). The collected data consisted of sociodemographic factors, general characteristics, associated diseases, and laboratory results. Adequate anthropometric measurements were conducted, and all subjects were required to complete the SF-36 RAND questionnaire. Results: The analysis identified several variables that independently influenced emotional well-being. These included pain intensity (beta (β) 0.21; 95% CI: 0.03-0.20; p < 0.01), social functioning (beta (β) 0.47; 95% CI: 0.23-0.43; p < 0.001), physical functioning (beta (β) 0.23; 95% CI: 0.04-0.21; p < 0.01), and education level (8-12 years: beta (β) 0.25; 95% CI: 1.47-9.41; p < 0.01; >12 years: beta (β) 0.27; 95% CI: 2.51-12.67; p < 0.01). However, the multivariate model revealed that only social functioning (beta (β) 0.57; 95% CI: 0.27-0.53; p < 0.001) and education level (8-12 years: beta (β) 0.21; 95% CI: 1.10-8.260; p < 0.05; >12 years: beta (β) 0.21; 95% CI: 1.18-10.30; p < 0.05) were significantly associated with emotional well-being in KOA patients. Conclusions: The findings of this study indicate that a reduced social functioning and a lower educational attainment are linked to a poorer emotional well-being among patients with KOA.

Mental Health Clinical Research Innovations during the COVID-19 Pandemic: The Future Is Now

The COVID-19 pandemic put an unprecedented strain on clinical research worldwide. As in-person clinical trials came to a screeching halt, we sought new ways to move forward, or as Bob Dylan put it, "start swimmin' or sink like a stone." Telemedicine has long been a part of medicine and clinical research, but fully remote clinical trials were few and far between. In the midst of the pandemic, at the Washington University School of Medicine we successfully conducted a fully remote clinical trial for a potential COVID-19 therapy, demonstrating the feasibility of fully remote or decentralized clinical trials.

[Diagnostic and therapeutic approach to sarcopenia]

Die Sarkopenie beschreibt einen generalisierten Verlust von Muskelkraft, -masse und -funktion. Sie geht mit reduzierter Lebensqualität und erhöhter Mortalität einher. Zur Identifizierung gefährdeter Patienten in der Primärversorgung dient der Screeningfragebogen für Sarkopenie (SARC-F), welcher fünf Funktionsbereiche des alltäglichen Lebens erfasst. Im Fall einer relevanten Einschränkung sollte die Messung der Handkraft mithilfe eines Dynamometers und/oder die Beinkraft mithilfe des Chair-Rising-Test erfolgen. Bei pathologischen Ergebnissen sollte der relative Skelettmuskelindex z. B. per Dual-Röntgen-Absorptiometrie bestimmt werden. Unterschreitet dieser den geschlechtsspezifischen Grenzwert, ist die Diagnose einer Sarkopenie zu stellen. Bei normwertiger Muskelmasse liegt eine Präsarkopenie vor. In beiden Fällen sollten die Ursachen abgeklärt und eine Therapie begonnen werden. Eine Verlaufsuntersuchung wird zur Differenzierung zwischen akuter und chronischer Sarkopenie und zur Beurteilung der Krankheitsprogression empfohlen.

Willingness to Participate in Health Research Among Community-Dwelling Middle-Aged and Older Adults: Does Race/Ethnicity Matter?

INTRODUCTION

Older adults, including racial and ethnic minorities, are underrepresented in research. As the US population ages, the number of older racial and ethnic minority individuals will increase. Including these individuals in research is an important step towards reducing health disparities.

METHODS

We used data from HealthStreet, a University of Florida community engagement program which uses community health workers to assess the health of the community, to assess willingness to participate in different types of health research by race/ethnicity. Descriptive statistics and logistic regression models were used to assess willingness to participate among adults aged 50 and older, by race/ethnicity (n = 4694).

RESULTS

Our sample was 42.0% non-Hispanic White, 52.8% non-Hispanic Black, and 5.2% Hispanic. Non-Hispanic White participants reported more past research participation than non-Hispanic Black and Hispanic participants (28.7% vs. 19.0% and 19.2%, respectively). Compared with non-Hispanic White participants, non-Hispanic Black participants were less willing to participate in most types of studies, while Hispanic participants were less willing to participate in studies that might be seen as invasive (required blood sample, genetic sample, or participants to take medicine, or use of medical equipment).

CONCLUSIONS

Our study provides investigators with a general profile of research preferences by race/ethnicity; compared with non-Hispanic White individuals, non-Hispanic Black individuals are less willing to participate in most studies, while Hispanic individuals are less willing to participate in studies that may be seen as invasive or demanding. It is imperative to include diverse older adults in health research. By tailoring research based on preferences we can improve recruitment in underrepresented populations.

Correlates related to follow-up in a community engagement program in North Central Florida

AIMS

This analysis identifies the correlates of 60- and 120-day telephone-based study follow-ups among community-dwelling adults in North Central Florida.

METHODS

Six thousand three hundred and forty participants were recruited by Community Health Workers from the University of Florida's community engagement program with a face-to-face baseline and two phone follow-ups assessing indicators of health.

RESULTS

Physical disability versus none (adjusted odds ratio [aOR], 1.5; 95% confidence interval [CI], 1.2─1.9), high trust in research versus none (aOR, 1.5; 95% CI, 1.1─2.1), history of research participation versus none (aOR, 1.6; 95% CI, 1.3─2.0), having health insurance versus none (aOR, 1.4; 95% CI, 1.1─1.7), interest in research participation versus none (aOR, 1.8; 95% CI, 1.3─2.7), and no drug use versus drug use (aOR, 0.5; 95% CI, 0.3─0.9) significantly predicted completion of follow-up.

CONCLUSIONS

Health and social factors such as disability, insurance, history of and interest in research, trust and no drug use significantly predicted completing two follow-ups. These findings can facilitate efforts to minimize attrition in the research enterprise.

Well-Being, Self-Efficacy and Independence in older adults: A Randomized Trial of Occupational Therapy

OBJECTIVE

The main objective of the research was to analyze whether there were differences in the effects of individual and group occupational therapy (OT) treatment on psychological well-being, self-efficacy and personal independence.

METHOD

A randomized clinical trial (N = 70; age = 85 years, SD = 4) comparing individual versus group occupational therapy treatment for 6 months was conducted. The evaluation was performed with the Barthel Index (Personal Independence), the Ryff Wellness Index (Well-being), the Global Self-Efficacy Scale (Self-efficacy) and the Geriatric Depression Scale (Affective state Scale).

RESULTS

Results showed a decrease in individual treatment scores in the variables autonomy, environmental mastery, personal growth and purpose in life, reflecting worse self-acceptance and negative well-being as well as a lower ability to maintain stable relationships. By contrast, group treatment users maintained more stable social relationships and exhibited a greater ability to resist social pressure, to develop their potential skills and to define their goals in life. There were statistically significant differences in overall self-efficacy (p < 0.001), emotional well-being (p < 0.001) and personal independence (p = 0.013), with better scores in group versus individual treatment.

CONCLUSIONS

Group occupational therapy interventions in older adults could be the treatment of choice in people with depressed state, improving their emotional well-being, sense of self-efficacy and level of personal independence in basic activities of daily living.

Occupational Therapy, Self-Efficacy, Well-Being in Older Adults Living in Residential Care Facilities: A Randomized Clinical Trial

Introduction: Choosing the type of treatment approach is as important as the treatment itself, also giving and important value to internal variables in the individual that can determine the evolution of the intervention. The main aim of this study is to determine whether individual and/or group occupational therapy leads to changes in generalized self-efficacy and psychological well-being, and to identify the type of therapy that has the best effects on older adults. Method: Prospective, randomized, comparing two treatment groups: individual and group therapy during 6 months. A total sample of 70 patients institutionalized in residential care homes for older adults with a mean age of 85 (SD = 4). Assessment was conducted using the General Self-Efficacy Scale and Ryff's Well-being Scale. For analyze the main dependent variables we used ANOVA for intra-subject and inter-subject factors and Pearson correlation between well-being and self-efficacy by type of treatment. Results: Groups were equivalent at baseline. The results show statistically significant differences between the two types of therapy, showing a positive correlation between well-being and self-efficacy, being greater at a group level than at and individual level. At the group level, practically all of variables measured in the participants were increased as shown in the results tables, including a better adaptation and predisposition to work four participants died while the study was being conducted. Conclusion: The clinical trial shows that older people in residential centers achieve an increase in emotional well-being and self-efficacy when they receive occupational therapy group, rather than individual treatment not being significant changes. Treatment group participants reported a positive experience and clinical benefits from training program. The clinical trial was registered in the U.S. National Institutes of Health (ClinicalTrials.gov) with NCT02906306 identifier.

A randomized control trial feasibility evaluation of an mHealth intervention for wheelchair skill training among middle-aged and older adults

BACKGROUND

Providing mobility skills training to manual wheelchair (MWC) users can have a positive impact on community participation, confidence and quality of life. Often such training is restricted or not provided at all because of the expense of, and limited access to, occupational and physical therapists before and after discharge. This is particularly true among middle-aged and older adults, who often have limited access to rehabilitation services and require more time to learn motor skills. A monitored MWC skills training home program, delivered using a computer tablet (mHealth), was developed as an alternative approach to service delivery. The purpose of this study was to evaluate the feasibility of implementing this mHealth MWC skills training program among middle-aged and older adults.

METHODS

A 2 × 2 factorial design randomized controlled trial (RCT) was used to compare the mHealth intervention and control groups, with additional wheeling time as a second factor. Community-dwelling MWC users aged 55 and older, who had used their MWC for less than two years and propelled with two hands, were recruited. Feasibility outcomes related to process, resources, management and treatment criteria were collected.

RESULTS

Eighteen participants were recruited, with a retention rate of 94%. Mean (±SD) duration for the first and second in-person training sessions were 90.1 ± 20.5 and 62.1 ± 5.5 min, respectively. In the treatment group, 78% achieved the minimum amount of home training (i.e., 300 min) over four weeks and 56% achieved the preferred training threshold (i.e., 600 min). Trainers reported only seven minor protocol deviations. No tablets were lost or damaged and there was one incident of tablet malfunction. No injuries or adverse incidents were reported during data collection or training activities. Participants indicated 98% agreement on the post-treatment benefit questionnaire.

DISCUSSION

Overall, the study protocol enabled implementation of the intervention in a safe, efficient and acceptable manner. Participant recruitment proved to be challenging, particularly gaining access to individuals who might benefit. Resource issue demands were acceptable for administration of the intervention; data collection was more time-consuming than anticipated but could be reduced with minor revisions. Participant retention and home program treatment adherence was high; both participant and trainer burden was acceptable. Treatment group participants reported a positive experience and clinical benefits from training program. The findings suggest a full-scale RCT evaluating the clinical impact of the Enhancing Participation In the Community by improving Wheelchair Skills (EPIC Wheels) intervention is warranted, provided the recruitment issues are addressed through collaborative partnerships and active recruitment strategies.

Efficacy of an Exercise and Nutritional Supplement Program on Physical Performance and Nutritional Status in Older Adults With Mobility Limitations Residing at Senior Living Facilities

This cluster-randomized trial was designed to determine the efficacy of a 6-month exercise-nutritional supplement program (ENP) on physical function and nutritional status for older adults and the feasibility of implementing this program in a senior living setting. Twenty senior-living facilities were randomized to either a 3 day per week group-based ENP led by a trained facility staff member or a health education program (SAP). Participants (N = 121) completed a short physical performance battery, 400-m walk, handgrip strength test, and mini-nutrition assessment. 25-hydroxyvitamin D [25(OH)D], insulin-like growth-factor 1 (IGF-1), and activity level were also measured. The ENP did not significantly improve physical function or nutritional status compared with the SAP. Compared with baseline, participants in the ENP engaged in 39 min less physical activity per week at 6 months. Several facility characteristics hindered implementation of the ENP. This study highlights the complexity of implementing an evidence-based program in a field setting.

Effect of Structured Physical Activity and Nutritional Supplementation on Physical Function in Mobility-Limited Older Adults: Results from the VIVE2 Randomized Trial

OBJECTIVES

The interactions between nutritional supplementation and physical activity on changes in physical function among older adults remain unclear. The primary objective of this study was to examine the impact of nutritional supplementation plus structured physical activity on 400M walk capacity in mobility-limited older adults across two sites (Boston, USA and Stockholm, Sweden).

DESIGN

All subjects participated in a physical activity program (3x/week for 24 weeks), involving walking, strength, balance, and flexibility exercises. Subjects were randomized to a daily nutritional supplement (150kcal, 20g whey protein, 800 IU vitamin D) or placebo (30kcal, non-nutritive).

SETTING

Participants were recruited from urban communities at 2 field centers in Boston MA USA and Stockholm SWE.

PARTICIPANTS

Mobility-limited (Short Physical Performance Battery (SPPB) ≤9) and vitamin D insufficient (serum 25(OH) D 9 - 24 ng/ml) older adults were recruited for this study.

MEASUREMENTS

Primary outcome was gait speed assessed by the 400M walk.

RESULTS

149 subjects were randomized into the study (mean age=77.5±5.4; female=46.3%; mean SPPB= 7.9±1.2; mean 25(OH)D=18.7±6.4 ng/ml). Adherence across supplement and placebo groups was similar (86% and 88%, respectively), and was also similar across groups for the physical activity intervention (75% and 72%, respectively). Both groups demonstrated an improvement in gait speed with no significant difference between those who received the nutritional supplement compared to the placebo (0.071 and 0.108 m/s, respectively (p=0.06)). Similar effects in physical function were observed using the SPPB. Serum 25(OH)D increased in supplemented group compared to placebo 7.4 ng/ml versus 1.3 ng/ml respectively.

CONCLUSION

Results suggest improved gait speed following physical activity program with no further improvement with added nutritional supplementation.
