Assessment of treatment burden and complexity in cystic fibrosis: A quality improvement project.

Background: Treatment regimens for cystic fibrosis (CF) continue to evolve and grow in complexity. Treatment regimen burden, and associated sequelae, are incompletely understood.

Objective: Quality improvement (QI) methods were used to investigate treatment burden of CF care, family and care team partnerships, and potential interventions to reduce burden.

Methods: Patients 6-24 years with CF and caregivers of patients 6-13 years were surveyed. Portions of validated tools and existing surveys measured burden and family-care team partnership. An automated report calculated treatment complexity. Plan-do-study-act cycles tested survey administration during CF visits and run charts tracked progress. Interventions to reduce burden were tracked, and bidirectional assessments explored partnerships among patients, families and clinicians.

Results: Over 6 months, 110 patients and 62 caregivers completed assessments. Caregivers reported lower burden/higher quality of life (74.0, range 22.2-100) than patients (66.5, range 16.7-100). The mean treatment complexity score was 17.2 (range 6-34). Treatment complexity and burden increased with patient age (p < .05 and p < .01 respectively). Lower lung function correlated with higher patient-reported burden (p < .01) and higher treatment complexity (p < .0001). As burden increased, providers more often performed select interventions (discussed combining treatments, simplified regimens, or involved other team members (p < .05 for each)). Families reported high partnership (mean scores 4.7-4.8, 5 = high), and providers reported high utilization of partnership tools (tool used in 77% of encounters).

Conclusion: We assessed, quantified, and responded to treatment burden and complexity in real-time during outpatient CF visits. Systematic and individualized assessments of treatment complexity and burden may enhance treatment adherence while preserving quality of life.
