Linking electronic health data in pharmacoepidemiology: Appropriateness and feasibility

Abstract

Purpose: To provide guidance on data linkage appropriateness and feasibility to plan purposeful and sustainable new linkages that advance pharmacoepidemiology and healthcare research. Planning a new data linkage requires careful evaluation to weigh the resources required with the potential overall benefits. Methods:In response to an International Society for Pharmacoepidemiology (ISPE) call for manuscripts, a working group comprised of members from academic, industry, and government determined priority content areas; appropriateness and feasibility of data linkage was selected. Within this topic, scientific and operational considerations were determined, reviewed, and formulated into key areas, and translated into 12 consensus recommendations.Results: Guidance for feasibility assessment was categorized into five key areas:(1) research objectives and justification; (2) data quality and completeness; (3) the linkage process; (4) data ownership and governance; and (5) overall value added by linkage. Within these key areas, recommendations to consider prior to initiation were developed to evaluate suitability of the linkage to meet research objectives, assess source data completeness and population coverage, and ensure well-defined data governance standards and protections. When creating novel linked datasets, researchers must assess the feasibility of both scientific (data quality and linkage methods) and operational (access, data use and transfer, governance, and cost) aspects. Conclusions:The data linkage feasibility assessment considerations outlined can be used as a guide when designing sustainable linked data resources to generate actionable evidence in healthcare research. These recommendations were constructed for wide applicability and can be adapted depending on the geographic, structural, and data components of the linkage.

Linking cohort-based data with electronic health records: a proof-of-concept methodological study in Hong Kong

“…It is also very important to assess the validity and practicability of the record-linkage beforehand to make sure that it is useful for researchers. 6 In many countries including Australia, 7 the USA, 8 Scotland, 9 New Zealand, 10 China 11 etc, data linkage has been practised in medical and social research.…”

The Certainty Framework for Assessing Real‐World Data in Studies of Medical Product Safety and Effectiveness

“…Numerous groups, including regulatory agencies, have published guidance and best practices on the conduct of observational studies in support of or for regulatory purposes 36–44 . Others have made clear the need for transparency in studies to the degree that they can be replicated (e.g., design diagrams with very clear documentation, code lists, covariate definitions, the assessment windows used for baseline characteristics, and risk windows) 45,46 .…”

Data linkage in pharmacoepidemiology: A call for rigorous evaluation and reporting

“…Because of the structure of the US health care system, a final linked dataset from such a scenario will include a highly selected population of patients who are (a) younger than age 65, (b) able to maintain enrollment in commercial health insurance after cancer diagnosis, (c) treated by oncology practices using certain interoperable software, and (d) living in states with cancer registries and data use agreements allowing linkage for research. Impacts for these selection factors could be managed through initial feasibility assessment (eg, recruiting additional partners/data sources to fill gaps for important populations of interest where linkage was poor relative to reference) or, where appropriate, statistically adjusting the final model with frequency weights to address over or under representation of particular patient populations.…”

“…The three topics of (a) planning and feasibility of data linkage, (b) evaluation of data linkage performance, and (c) reporting of data linkage in peer‐reviewed publications were identified as priority topics. A companion paper titled Linking Electronic Health Data in Pharmacoepidemiology: Appropriateness and Feasibility addresses the first topic . This paper addresses the latter two topics with the aim of developing a checklist for evaluation of data linkage performance and reporting data linkage specifically for pharmacoepidemiologic research.…”
