Background: Over the last 20 years, cancer care has transitioned from long hospitalizations to short inpatient stays or outpatient settings. As patients and their family members increasingly turn to the Internet for health information, cancer hospitals have the opportunity to provide clear, credible information on their websites to cancer patients, families, and informal caregivers. Objective: Recommend improved web content and organization of caregiver information for patients and families at our local comprehensive cancer center. Methods: One librarian and two library science students conducted a cognitive walk-through to assess websites of two cancer hospitals in the Mid-Atlantic Region. Each evaluator independently performed seven tasks distributed among three different caregiver personas to evaluate the presence and accessibility of caregiver information on these cancer hospital websites.Results: Our findings indicate that these websites are not conducive to providing information for cancer caregiver support because of the following: key information is unavailable, navigation on the landing page is limited, broken links, ambiguous page titles, page titles that do not match the content of the page, and lack of contact information (phone number, email) for service access. Conclusion: Opportunities are available to improve cancer caregiver information on cancer hospital websites. Library professionals can help cancer hospitals improve caregiver information on their websites with recommendations for additional content and clearer organization. This is a way to build partnerships between library professionals and cancer hospitals.
