New Recommendations on the Critical Appraisal of Systematic Reviews With Cost and Cost-Effectiveness Outcomes

Published Apr 13, 2021

Global Panel Developed New ISPOR Good Practices Report

Value in HealthLawrenceville, NJ, USA—April 13, 2021—ISPOR, the professional society for health economics and outcomes research, announced today the publication of new guidance on how to evaluate the quality and risk of bias in systematic reviews with cost and cost-effectiveness outcomes. The report, “Critical Appraisal of Systematic Reviews With Cost and Cost-Effectiveness Outcomes: An ISPOR Good Practices Task Force Report” and the accompanying ISPOR Criteria for Cost-Effectiveness Review Outcomes (CiCERO) Checklist was published in the April 2021 issue of Value in Health, the official journal is ISPOR.

This ISPOR Good Practices Report provides guidance to researchers, producers of health technologies, decision makers, and evidence users, on how to minimize the risk of bias as well as improve the quality of methods and reporting for conducting systematic reviews with cost and cost-effectiveness outcomes. “With the increasing number of systematic reviews with cost and cost-effectiveness outcomes, standardizing the preparation, reporting, and interpretation of their findings is incredibly important because it can improve their overall quality, providing better information on the economic value of a health technology, ultimately, improving healthcare decision making,” said task force co-chair J.L. (Hans) Severens, Erasmus University, Rotterdam, The Netherlands.

A systematic review can provide rigorous and complete evidence to support decision makers who consider both the effectiveness and cost-effectiveness of health interventions. First, such reviews help to identify strengths and weaknesses in health economic studies, modelling methodologies, and data for modelling inputs. Second, they can inform decisions in resource allocation for health interventions, especially in countries with limited capacity for health technology assessment. However, it is difficult to appropriately interpret systematic reviews with cost- and cost-effectiveness outcomes due to the differences in methodology and due to variability in clinical and health settings in the original studies that are included.

“We initiated this task force to address the differences in methodological guidance. Moreover, assessing the quality and risk of bias using CiCERO will identify the review’s critical weaknesses and give the user a feeling of overall confidence in the results of the systematic review,” said Olena (Lena) Mandrik, PhD, task force co-chair The University of Sheffield, Sheffield, England, UK. She added, “Developing good practices and a standardized approach to conduct these reviews helps all of the healthcare stakeholders involved.”

The report describes good practice recommendations organized in 6 stages. Based on these stages, the international task force developed and extensively tested the ISPOR CiCERO Checklist. There are 3 versions of the CiCERO checklist for (1) reviews of cost and cost-effectiveness studies; (2) reviews that summarize methods of cost and cost-effectiveness studies; and (3) systematic reviews with cost and cost-effectiveness outcomes that use the AMSTAR-2 instrument to assess quality in included studies.

With healthcare costs rising every year, providing decision makers with the best possible tools for assessing the quality and risk of bias in systematic reviews with cost and cost-effectiveness outcomes will only grow in importance.
