A Quality Improvement Initiative to Improve Patient Adherence to Vitamin Supplementation in Cystic Fibrosis.

OBJECTIVES: Patients with cystic fibrosis (CF) and pancreatic insufficiency are prescribed fat-soluble vitamins, although compliance remains low. Our objective was to identify patient and caregiver knowledge deficits regarding vitamin supplementation, provide targeted education, and examine serum vitamin levels pre-and posteducation.

METHODS: This prospective quality improvement study involved 118 patients. A vitamin knowledge survey was given to patients/caregivers during a clinic visit, education was provided targeting knowledge deficits, and the survey was re-administered at the next clinic visit. Serum vitamin levels were collected at pre- and postsurvey.

RESULTS: Results showed significant pre-post increases for patient and caregiver knowledge scores, and significant decreases in self-reported nonadherence to vitamin use and number of reported barriers affecting adherence. A significant change in vitamin E level to therapeutic range post-education was demonstrated.

CONCLUSIONS: Our brief, targeted educational interventions regarding vitamin supplementation showed utility in a routine clinic setting.
