Review: Casefinding Sources

Here is what we have learned from Casefinding Sources:

  • There are many casefinding sources; reliance on multiple sources is necessary to obtain a complete description of the patient's cancer experience.
  • Daily or weekly review of all inpatient and outpatient admissions and discharges facilitates quick casefinding process since these documents present clinical or pathological diagnosis of cancer.
  • Using disease indices as the source documents in casefinding, the registrar must determine what the hospital-specific guidelines are for coding certain diagnoses to ensure the accuracy of the codes used to identify cancer cases in the hospital.
  • The accuracy of surgery schedules as a source of casefinding depends on appropriate documentation of orders and diagnoses at the time of surgery.
  • One of the methods of casefinding in the pathology department is to review a computer listing of coded final histologic diagnoses.
  • If the pathology department is not computerized or does not use ICD-O codes to code histology, the registrar must manually review each pathology report.
  • Both computerized and manual methods of reviewing pathology reports must include a way to track reports to ensure that each report has been included in the registrar's review.
  • Other casefinding sources include cytology and autopsy reports, nuclear medicine documents, radiation oncology and medical oncology logs.
