Validation of Algorithms to Identify Bone Metastases Using Administrative Claims Data in a Japanese Hospital.

ABSTRACT:

Background

Validated coding algorithms are essential to generate high-quality, real-world evidence from claims data studies.

Objective

We aimed to evaluate the validity of the algorithms to identify patients with bone metastases using claims data from a Japanese hospital.

Patients and methods

This study used administrative claims data and electronic medical records at Juntendo University Hospital from April 2017 to March 2019. We developed two candidate claims-based algorithms to detect bone metastases, one based on diagnosis codes alone (Algorithm 1) and the other based on the combination of diagnosis and imaging test codes (Algorithm 2). Of the patients identified by Algorithm 1, 100 patients were randomly sampled. Among these 100 patients, 88 patients met the condi
