HARmonized Protocol Template to Improve Reproducibility (HARPER) – Healthcare Economist


Scientific trials have detailed research protocols and are registered on ClinicalTrials.gov. What degree of particulars are wanted for real-world knowledge (RWD) analyses that goal to estimate therapy results? In Europe, the European Medicines Company (EMA) requires registration of many research protocols utilizing a template for observational post-authorization security research (PASS) carried out by advertising and marketing authorization holders. Different efforts embrace ISPE’s tips for good pharmacoepidemiology follow (GPP) part on protocol improvement, Nationwide Analysis System for well being Expertise (NEST) protocol steerage, and the Structured Template and Reporting Instrument for Actual World Proof (STaRT-RWE).

The Worldwide Society for Pharmacoepidemiology (ISPE) and the Worldwide Society for Pharmacoeconomics and Outcomes Analysis (ISPOR) convened a joint activity pressure to supply requirements for RWD protocols. They developed the HARmonized Protocol Template to Improve Reproducibility (HARPER). The Desk beneath compares HARPER towards PASS, GPP, NEST and STaRT-RWE.

The authors correctly be aware just a few limitations of HARPER.

  • Structured vs. Flexibility. HARPER’s structured method enhances readability for stakeholders and consistency throughout research. Nonetheless, some complicated research designs could also be fully cheap, however could not match throughout the HARPER construction. Lots of the sections, nonetheless, comprise free textual content sections.
  • Minimal, not most transparency. HARPER doesn’t cowl each side of transparency over the lifecycle of a analysis research, which can contain sharing of protocol, code, knowledge, in addition to outcomes. Thus, HARPER ought to be seen because the minimal necessities for research protocol transparency.
  • Knowledge evolution. As knowledge assortment evolves and new strategies are developed, HARPER’s method could must adapt over time.
