A Systematic Review of Methods to Incorporate External Evidence into Trial-Based Survival Extrapolations for Health Technology Assessment.

ABSTRACT:

Background

External evidence is commonly used to inform survival modeling for health technology assessment (HTA). While there are a range of methodological approaches that have been proposed, it is unclear which methods could be used and how they compare.

Purpose

This review aims to identify, describe, and categorize established methods to incorporate external evidence into survival extrapolation for HTA.

Data sources

Embase, MEDLINE, EconLit, and Web of Science databases were searched to identify published methodological studies, supplemented by hand searching and citation tracking.

Study selection

Eligible studies were required to present a novel extrapolation approach incorporating external evidence (i.e., data or information) within survival model estimatio
