What does the term "non-analytic" specifically refer to in terms of patient treatment?

The term "non-analytic" specifically refers to patients who are diagnosed and treated entirely outside the registry facility. This classification is important for several reasons within cancer registries. Non-analytic cases do not contribute to the analysis of treatment and outcomes within the registry, as they were not treated in the reporting facility. This distinction helps ensure that the data captured in the registry accurately reflects the treatment outcomes of patients who were treated within that specific healthcare system.

Patients receiving treatment exclusively in the registry facility are considered "analytic" cases because their diagnosis and treatment are fully encompassed within the facility's records. Understanding the definitions of analytic and non-analytic cases is crucial for registrars when coding and reporting case data for cancer statistics and research. It allows for clearer demographic and outcome analyses based on where patients received their care.
