Key Findings from a Transformative Quality Improvement Initiative on Advancing CAR T-Cell Treatment in Non-Hodgkin Lymphoma

Background

Chimeric antigen receptor (CAR) T-cell therapy can transform outcomes for eligible patients with relapsed/refractory non-Hodgkin lymphoma (NHL). However, community-based care teams face challenges, including identifying eligible patients and coordinating referral and care, hindering integration into clinical practice. PRIME conducted a quality improvement (QI) initiative to better understand the challenges community oncology teams encounter in coordinating CAR T-cell therapy for patients with NHL and to bridge the gap between tertiary referral centers and large CAR T-cell centers.

Methods

This QI initiative included baseline provider surveys (n = 60), pre- and post-surveys of providers (n = 55) participating in team-based audit-feedback (AF) sessions (Table 1) and 90-day follow-up surveys. Survey questions were designed to evaluate practice patterns, challenges, and barriers to providing CAR T cell therapy to NHL patients. Care teams from each clinic, along with a CAR T-cell expert from the regional academic center and nationally renowned expert NHL CAR T-cell physician, participated in AF sessions to (a) assess system-specific practice gaps identified via the provider surveys, (b) prioritize areas for improvement, and (c) develop action plans for addressing root causes.

Results

Provider Surveys: Providers' top reported challenges managing patients with NHL were individualizing treatment plans (33%), patient nonadherence/lack of follow-up (23%), and patient health literacy (20%). Specific barriers to using CAR T-cell therapy included identifying patients eligible for treatment (45%), gaining approval from the insurance company (40%), and transferring the patient to a CAR T-cell center for infusion (27%). When asked about clinical practices, 48% of providers reported discussing novel therapies for NHL in detail with their patients, and 51% of providers often or always refer eligible patients for CAR T-cell therapy. While 45% of providers rated the level of collaboration/communication between CAR T-cell centers and oncology clinics as very good/excellent, more than half felt it could be better, citing insufficient sharing of patient information (38%), and lack of expertise in CAR T-cell administration among clinic staff (18%) as common challenges.

Small Group AF Sessions: HCPs participating in the A/F sessions reported key challenges of treatment with CAR T-cell therapy as gaining approval from insurance companies (33%), managing patients post-treatment (26%), and identifying patients eligible for treatment (22%) (Figure 1).Improvement in very high/high confidence were noted in identifying eligible patients for CAR T-cell therapy (51% to 84%) and managing adverse/late effects of CAR T-cell therapy in patients with NHL (46% to 85%). Action plans outlined to achieve CAR T-Cell therapy goals included: increase efforts to facilitate timely patient referrals for CAR T-cell therapy, improve communication between referral centers and CAR T-cell therapy performing centers, and enhance patient knowledge and expand supportive care discussions for CAR T-cell therapy.

Follow-up Surveys: In 90-day follow up surveys (n = 12), 92% of respondents reported good/very good/excellent communication and collaboration between CAR T-cell centers and oncology clinics. Additionally, 75% report improved identification of eligible patients for CAR T-cell therapy. Despite these improvements, clinics top challenge of gaining approval from the insurance company for CAR T-cell therapy (33%) persists.

Conclusions

Through this QI initiative, clinical teams created and implemented action plans to close gaps in identifying eligible patients, coordinating CAR T-cell therapy referral and approval, and providing counseling and obtaining consent among hematology/oncology team members. Following the initiative, meaningful confidence gains were noted in identifying eligible patients for CAR T-cell therapy and managing adverse/late effects of treatment. Action plans developed by HCPs following this QI initiative, will be addressed in future initiatives to support evidence-based integration of CAR T-cell therapies into NHL care to optimize patient outcomes.
