A pilot study of direct care nurse (DCN) education to improve adherence and knowledge of erlotinib in patients with non-small cell lung cancer.
e19637 Background: Adherence for oral anticancer agents is a major concern for patients in the ambulatory setting. Adherence rates for oral medication regimens are associated with proper knowledge and monitoring for adverse side effects including symptom management. To improve patient-reported adherence we studied feasibility of a DCN educational intervention to enhance participant knowledge and adherence to erlotinib while monitoring for side effects. Methods: A prospective, pilot study with 30 NSCLC patients was conducted. The study included a DCN structured education session utilizing an adapted educational tool (MOATT) from the Multinational Association of Supportive Care in Cancer (MASCC); followed within 72 hours by a DCN phone call to assess patient learning, adherence, and adverse side effects. Primary endpoints included participant-reported Knowledge Rating Scale (KRS) scores and adherence behaviors measured by the Morisky Medication Adherence Scale (MMAS-8). Adverse side effects and feasibility data were analyzed for each DCN/patient encounter. Results: MMAS-8 adherence scores indicated medium (n=11) to high (n=14) adherence rates and high KRS scores (mean 8.9, range of 7.5-10). Mean age of patients was 67 years (range 45-84 years), majority were female (81%), with race/ethnicity as Caucasian 80%, Asian 10%, and Black 10%. Mean number of erlotinib adverse events was 2.48 per patient and 22% reported 4 or more side effects. Patients contacted DCN 60 times between start and end of protocol. Feasibility included 90% (n=27/30) completing the protocol, mean time 30 minutes to administer educational session and 14 minutes for DCN 72-hour follow-up phone call. Documentation of visits indicated nurse education and follow-up, including monitoring side effects, provided valued supportive care. Conclusions: Data supports the need for and feasibilty of a nurse-led structured protocol to enhance adherence, knowledge, and symptom management. Further study of this education/monitoring intervention for patients initiating oral anticancer agents in the ambulatory setting is recommended.
