African American Recruitment in Early Heart Failure Palliative Care Trials: Outcomes and Comparison With the ENABLE CHF-PC Randomized Trial

BACKGROUND

Palliative care trial recruitment of African Americans (AAs) is a formidable research challenge.

OBJECTIVES

Examine AA clinical trial recruitment and enrollment in a palliative care randomized controlled trial (RCT) for heart failure (HF) patients and compare patient baseline characteristics to other HF palliative care RCTs.

METHODS

This is a descriptive analysis the ENABLE CHF-PC (Educate, Nurture, Advise, Before Life Ends: Comprehensive Heartcare for Patients and Caregivers) RCT using bivariate statistics to compare racial and patient characteristics and differences through recruitment stages. We then compared the baseline sample characteristics among three palliative HF trials.

RESULTS

Of 785 patients screened, 566 eligible patients with NYHA classification III-IV were approached; 461 were enrolled and 415 randomized (AA = 226). African Americans were more likely to consent than Caucasians (55%; P FDR = .001), were younger (62.7 + 8; P FDR = .03), had a lower ejection fraction (39.1 + 15.4; PFDR = .03), were more likely to be single (P FDR = .001), and lack an advanced directive (16.4%; P FDR < .001). AAs reported higher goal setting (3.3 + 1.3; P FDR = .007), care coordination (2.8 + 1.3; P FDR = .001) and used more "denial" coping strategies (0.8 + 1; P FDR = .001). Compared to two recent HF RCTs, the ENABLE CHF-PC sample had a higher proportion of AAs and higher baseline KCCQ clinical summary scores.

CONCLUSION

ENABLE CHF-PC has the highest reported recruitment rate and proportion of AAs in a palliative clinical trial to date. Community-based recruitment partnerships, recruiter training, ongoing communication with recruiters and clinician co-investigators, and recruiter racial concordance likely contributed to successful recruitment of AAs. These important insights provide guidance for design of future HF palliative RCTs.

Effect of an Early Palliative Care Telehealth Intervention vs Usual Care on Patients With Heart Failure: The ENABLE CHF-PC Randomized Clinical Trial

IMPORTANCE

National guidelines recommend early palliative care for patients with advanced heart failure, which disproportionately affects rural and minority populations.

OBJECTIVE

To determine the effect of an early palliative care telehealth intervention over 16 weeks on the quality of life, mood, global health, pain, and resource use of patients with advanced heart failure.

DESIGN, SETTING, AND PARTICIPANTS

A single-blind, intervention vs usual care randomized clinical trial was conducted from October 1, 2015, to May 31, 2019, among 415 patients 50 years or older with New York Heart Association class III or IV heart failure or American College of Cardiology stage C or D heart failure at a large Southeastern US academic tertiary medical center and a Veterans Affairs medical center serving high proportions of rural dwellers and African American individuals.

INTERVENTIONS

The ENABLE CHF-PC (Educate, Nurture, Advise, Before Life Ends Comprehensive Heartcare for Patients and Caregivers) intervention comprises an in-person palliative care consultation and 6 weekly nurse-coach telephonic sessions (20-40 minutes) and monthly follow-up for 48 weeks.

MAIN OUTCOMES AND MEASURES

Primary outcomes were quality of life (as measured by the Kansas City Cardiomyopathy Questionnaire [KCCQ]: score range, 0-100; higher scores indicate better perceived health status and clinical summary scores ≥50 are considered "fairly good" quality of life; and the Functional Assessment of Chronic Illness Therapy-Palliative-14 [FACIT-Pal-14]: score range, 0-56; higher scores indicate better quality of life) and mood (as measured by the Hospital Anxiety and Depression Scale [HADS]) over 16 weeks. Secondary outcomes were global health (Patient Reported Outcome Measurement System Global Health), pain (Patient Reported Outcome Measurement System Pain Intensity and Interference), and resource use (hospital days and emergency department visits).

RESULTS

Of 415 participants (221 men; baseline mean [SD] age, 63.8 [8.5] years) randomized to ENABLE CHF-PC (n = 208) or usual care (n = 207), 226 (54.5%) were African American, 108 (26.0%) lived in a rural area, and 190 (45.8%) had a high-school education or less, and a mean (SD) baseline KCCQ score of 52.6 (21.0). At week 16, the mean (SE) KCCQ score improved 3.9 (1.3) points in the intervention group vs 2.3 (1.2) in the usual care group (difference, 1.6; SE, 1.7; d = 0.07 [95% CI, -0.09 to 0.24]) and the mean (SE) FACIT-Pal-14 score improved 1.4 (0.6) points in the intervention group vs 0.2 (0.5) points in the usual care group (difference, 1.2; SE, 0.8; d = 0.12 [95% CI, -0.03 to 0.28]). There were no relevant between-group differences in mood (HADS-anxiety, d = -0.02 [95% CI, -0.20 to 0.16]; HADS-depression, d = -0.09 [95% CI, -0.24 to 0.06]).

CONCLUSIONS AND RELEVANCE

This randomized clinical trial with a majority African American sample and baseline good quality of life did not demonstrate improved quality of life or mood with a 16-week early palliative care telehealth intervention. However, pain intensity and interference (secondary outcomes) demonstrated a clinically important improvement.

Effects of a Telehealth Early Palliative Care Intervention for Family Caregivers of Persons With Advanced Heart Failure: The ENABLE CHF-PC Randomized Clinical Trial

IMPORTANCE

Family caregivers of persons with advanced heart failure perform numerous daily tasks to assist their relatives and are at high risk for distress and poor quality of life.

OBJECTIVE

To determine the effect of a nurse-led palliative care telehealth intervention (Educate, Nurture, Advise, Before Life Ends Comprehensive Heart Failure for Patients and Caregivers [ENABLE CHF-PC]) on quality of life and mood of family caregivers of persons with New York Heart Association Class III/IV heart failure over 16 weeks.

DESIGN, SETTING, AND PARTICIPANTS

This single-blind randomized clinical trial enrolled caregivers aged 18 years and older who self-identified as an unpaid close friend or family member who knew the patient well and who was involved with their day-to-day medical care. Participants were recruited from outpatient heart failure clinics at a large academic tertiary care medical center and a Veterans Affairs medical center from August 2016 to October 2018.

INTERVENTION

Four weekly psychosocial and problem-solving support telephonic sessions lasting between 20 and 60 minutes facilitated by a trained nurse coach plus monthly follow-up for 48 weeks. The usual care group received no additional intervention.

MAIN OUTCOMES AND MEASURES

The primary outcomes were quality of life (measured using the Bakas Caregiver Outcomes Scale), mood (anxiety and/or depressive symptoms measured using the Hospital Anxiety and Depression Scale), and burden (measured using the Montgomery-Borgatta Caregiver Burden scales) over 16 weeks. Secondary outcomes were global health (measured using the PROMIS Global Health instrument) and positive aspects of caregiving.

RESULTS

A total of 158 family caregivers were randomized, 82 to the intervention and 76 to usual care. The mean (SD) age was 57.9 (11.6) years, 135 (85.4%) were female, 82 (51.9%) were African American, and 103 (65.2%) were the patient's spouse or partner. At week 16, the mean (SE) Bakas Caregiver Outcomes Scale score was 66.9 (2.1) in the intervention group and 63.9 (1.7) in the usual care group; over 16 weeks, the mean (SE) Bakas Caregiver Outcomes Scale score improved 0.7 (1.7) points in the intervention group and 1.1 (1.6) points in the usual care group (difference, -0.4; 95% CI, -5.1 to 4.3; Cohen d = -0.03). At week 16, no relevant between-group differences were observed between the intervention and usual care groups for the Hospital Anxiety and Depression Scale anxiety measure (mean [SE] improvement from baseline, 0.3 [0.3] vs 0.4 [0.3]; difference, -0.1 [0.5]; d = -0.02) or depression measure (mean [SE] improvement from baseline, -0.2 [0.4] vs -0.3 [0.3]; difference, 0.1 [0.5]; d = 0.03). No between-group differences were observed in the Montgomery-Borgatta Caregiver Burden scales (d range, -0.18 to 0.0). Differences in secondary outcomes were also not significant (d range, -0.22 to 0.0).

CONCLUSIONS AND RELEVANCE

This 2-site randomized clinical trial of a telehealth intervention for family caregivers of patients with advanced heart failure, more than half of whom were African American and most of whom were not distressed at baseline, did not demonstrate clinically better quality of life, mood, or burden compared with usual care over 16 weeks. Future interventions should target distressed caregivers and assess caregiver effects on patient outcomes.
