Which of the following is an accepted source for obtaining follow-up information?

Obituary listings are an accepted source for obtaining follow-up information, particularly in cancer registries and survival analysis. They provide vital information on patient outcomes, specifically regarding mortality. When patients pass away, obituary listings can help registries confirm vital status and the cause of death, which is essential for maintaining accurate records and contributing to cancer epidemiology research. This information can also be critical in evaluating long-term survival rates and the effectiveness of cancer treatments.

While other options may provide some information relevant to patient follow-up, obituary listings specifically address the need for clear and direct data regarding mortality, thus fitting the criteria as a reliable source for follow-up in the context of cancer data collection and analysis.
