Research has found that patients sometimes have trouble obtaining oral (by mouth) cancer medications, understanding how to take these pills, handling side effects related to these drugs, and remembering to take these medications. The purpose of this research study is to have direct care nurses (DCNs) in the Thoracic Oncology Program (TOP) clinic provide teaching and follow-up to patients starting erlotinib (using a teaching tool) and to test the feasibility of providing education and follow-up. This study will also evaluate if increasing knowledge about erlotinib helps participants manage side effects and stay on their erlotinib without interruptions.

• Participants with non-small cell lung cancer will be asked to join this study after they have decided with their health care provider to start treatment with erlotinib (a pill).
• Educational Session 1 (Day that erlotinib is prescribed): During this clinic visit the physician or nurse practitioner will provide the participant with the DFCI Erlotinib Fact Sheet that reviews how to take the oral cancer medication and possible side effects to watch for. The TOP nurse will discuss the study and consent the participant. The TOP nurse will also provide participants with an Erlotinib Drug Log and instruct them on how use it to keep track of taking the erlotinib.
• Educational Session 2 (Within 72 hours of starting erlotinib): During this educational session, participants will talk with the TOP nurse by phone or in the clinic. The TOP nurse will use an oral cancer medication teaching tool (MOATT - Parts 1-4) to provide additional education about erlotinib. The MOATT tool was developed by the Multinational Association for Supportive Care in Cancer. This session will take about 20-30 minutes. Feasibility information will also be recorded by the nurse.
• Educational Session 3 (Phone follow-up 72 hours after Session 2): During this phone session, the TOP nurse will administer Parts 3-4 of the MOATT and discuss any side effects the participant is experiencing. This session will take 15-30 minutes. Feasibility information will also be documented.
• Educational Session 4 (First clinic visit after starting on Erlotinib): The TOP nurse will meet with the participant during their first DFCI clinic visit (with their physician or nurse practitioner), after starting erlotinib. During this session the participant will complete the Morisky Medication Adherence Scale 8-Item (MMAS-8), a Knowledge Rating Scale, and a demographic form. Parts 3-4 of the MOATT will also be administered, the Erlotinib Drug Log will be collected, and side effects will be discussed/recorded. This meeting will add 30-40 minutes to the clinic visit.
• After the participant completes Educational Session 4, their participation in the study will end.
