Designing the fostering inclusivity in research engagement for underrepresented populations in Parkinson's disease study

Sexual Orientation, Gender Identity, and Experiences During, Awareness of, and Attitudes Toward Research for People With Parkinson Disease

Background and Objectives

Presentation, progression, and treatment of Parkinson disease (PD) can differ based on sex and gender. However, knowledge on PD is limited by the characteristics of research participants, and most of the participants are men. In this study, we aimed to identify the attitudes toward and barriers to research participation for people with PD (PwP) based on their sexual orientation and gender identity.

Methods

Data were obtained from the Fox Insight on March 16, 2023, for PwP who completed the Attitudes and Beliefs Regarding Research and Genetic Testing for PD. Responses were compared between sexual and gender minorities (SGM) (n = 136), cisgender heterosexual women (n = 1,479), and cisgender heterosexual men (n = 1,445). Associations between age, socioeconomic variables, and the responses that differed between the groups were assessed with linear models.

Results

More than 68% of the participants were willing to participate in research; only 43.7% heard about research opportunities, and 52.3% knew where to find a study. Approximately 86.8% of the participants reported hearing about a study from their doctor would make them more likely to participate. A higher percentage of SGM were concerned about transportation and researchers not understanding or respecting their beliefs; a higher percentage of cisgender heterosexual women were concerned about transportation, data privacy, and their family's reaction to genetic results; and a higher percentage of cisgender heterosexual men were concerned about time required for research activities and complex forms. Age and socioeconomic variables were significantly associated with approach toward research that differed between the groups.

Discussion

PwP are willing to participate in research, and health care providers can facilitate their participation. Barriers to research participation related to sexual and gender identity exist and must be addressed to increase our understanding of PD in underrepresented populations.

Fostering Inclusivity in Research Engagement for Underrepresented Populations in Parkinson's Disease: The FIRE-UP PD study

BACKGROUND

Members of vulnerable populations are underrepresented in Parkinson's disease (PD) research. A complex web of research barriers perpetuates this gap. Community-based research methods are one approach to addressing this issue. The present PD study was designed to examine the effectiveness of community-based interventions to overcome barriers and increase research participation among underrepresented groups (URGs).

METHODS

Eight study sites across the US were selected and paired based on proposed interventions with specific URGs. Surveys assessed knowledge and attitudes toward PD research. Finally, researchers examined whether the present study affected recruitment to Fox Insight, an online PD research study also recruiting at each site.

RESULTS

In total, 474 participants were recruited. At post-intervention for the FIRE-UP PD Study, recruitment increased significantly in intervention compared to control sites among Black and African American non-Hispanic/Latino populations (p = 0.003), White Hispanic/Latino (p = 0.003) populations, and Not Listed Hispanic/Latino populations (p < 0.001) as well as those with an educational attainment of a high school diploma/General Education Diploma (GED) (p = 0.009), and an income <$20,000 (p = 0.005) or between $20,000-$34,999 (p < 0.001). Study surveys measuring changes in awareness and attitudes toward PD research had mixed results. In Fox Insight, 181 participants were passively recruited with a shift toward more diverse participant demographics.

CONCLUSION

Research participation demographics reflective of the general population are critical to PD investigation and treatment. The FIRE-UP PD Study showed the effectiveness of localized community engagement strategies in increasing URG recruitment to PD research. Therefore, further PD research employing community-based methods to improve diverse participant recruitment is needed.

Diversifying the research landscape: Assessing barriers to research for underrepresented populations in an online study of Parkinson's disease

Despite federal regulations mandating the inclusion of underrepresented groups in research, recruiting diverse participants remains challenging. Identifying and implementing solutions to recruitment barriers in real time might increase the participation of underrepresented groups. Hence, the present study created a comprehensive dashboard of barriers to research participation. Barriers to participation were recorded in real time for prospective participants. Overall, 230 prospective participants expressed interest in the study but were unable to join due to one or more barriers. Awareness of the most common obstacles to research in real time will give researchers valuable data to meaningfully modify recruitment methods.

Improving naturalistic neuroscience with patient engagement strategies

Introduction

The clinical implementation of chronic electrophysiology-driven adaptive deep brain stimulation (DBS) algorithms in movement disorders requires reliable representation of motor and non-motor symptoms in electrophysiological biomarkers, throughout normal life (naturalistic). To achieve this, there is the need for high-resolution and -quality chronic objective and subjective symptom monitoring in parallel to biomarker recordings. To realize these recordings, an active participation and engagement of the investigated patients is necessary. To date, there has been little research into patient engagement strategies for DBS patients or chronic electrophysiological recordings.

Concepts and results

We here present our concept and the first results of a patient engagement strategy for a chronic DBS study. After discussing the current state of literature, we present objectives, methodology and consequences of the patient engagement regarding study design, data acquisition, and study infrastructure. Nine patients with Parkinson's disease and their caregivers participated in the meeting, and their input led to changes to our study design. Especially, the patient input helped us designing study-set-up meetings and support structures.

Conclusion

We believe that patient engagement increases compliance and study motivation through scientific empowerment of patients. While considering patient opinion on sensors or questionnaire questions may lead to more precise and reliable data acquisition, there was also a high demand for study support and engagement structures. Hence, we recommend the implementation of patient engagement in planning of chronic studies with complex designs, long recording durations or high demand for individual active study participation.

IN-HOME-PD: The effects of longitudinal telehealth-enhanced interdisciplinary home visits on care and quality of life for homebound individuals with Parkinson's disease

INTRODUCTION

Homebound individuals with advanced Parkinson's disease (PD) are underrepresented in research and care. We tested the impact of interdisciplinary, telehealth-enhanced home visits (IN-HOME-PD) on patient quality of life (QoL) compared with usual care.

METHODS

Nonrandomized controlled trial of quarterly, structured, telehealth-enhanced interdisciplinary home visits focused on symptom management, home safety, medication reconciliation, and psychosocial needs (ClinicalTrials.gov NCT03189459). We enrolled homebound participants with advanced PD (Hoehn & Yahr (HY) stage ≥3). Usual care participants had ≥2 visits in the Parkinson's Outcomes Project (POP) registry. We compared within- and between-group one-year change in QoL using the Parkinson's Disease Questionnaire.

RESULTS

Sixty-five individuals enrolled in IN-HOME-PD (32.3% women; mean age 78.9 (SD 7.6) years; 74.6% white; 78.5% HY ≥ 4) compared with 319 POP controls, with differences in age, race, and PD severity (37.9% women; mean age 70.1 (7.8) years; 96.2% white; 15.1% HY ≥ 4). Longitudinally, the intervention group's QoL remained unchanged (within-group p = 0.74, Cohen's d = 0.05) while QoL decreased over time in POP controls (p < 0.001, Cohen's d = 0.27). The difference favored the intervention (between-group p = 0.04). POP participants declined in 7/8 dimensions while IN-HOME-PD participants' bodily discomfort improved and hospice use and death at home-markers of goal-concordant care-far exceeded national data.

CONCLUSIONS

Telehealth-enhanced home visits can stabilize and may improve the predicted QoL decline in advanced PD via continuity of care and facilitating goal-concordant care, particularly among diverse populations. Extrapolating features of this model may improve continuity of care and outcomes in advanced PD.
