Medical record retrieval for validating adverse events of special interest (AESI) algorithms in Medicare had a 47.9% success rate. Procedures used may improve future retrieval efforts for these important patient safety indicators.

Area of Science:

  • Health Services Research
  • Pharmacovigilance
  • Data Science in Healthcare

Background:

  • Claims-based algorithms are crucial for identifying adverse events of special interest (AESI) in large populations.
  • Validating these algorithms with medical records is essential for ensuring accuracy and reliability.
  • Medicare data offers a valuable resource for studying health outcomes in diverse patient groups.

Purpose of the Study:

  • To describe the process and outcomes of medical record retrieval for a study validating claims-based algorithms.
  • To assess the feasibility of identifying seven AESI in a Medicare population using claims data.
  • To inform future research on improving medical record retrieval rates.

Main Methods:

  • Analysis of 2010-2011 Medicare claims data for beneficiaries with specific conditions.
Keywords:

  • Random selection of beneficiaries identified by AESI algorithms for medical record retrieval.
  • Direct request for medical records from healthcare providers, without patient contact.

    • Main Results:

    • A total of 3331 beneficiaries were selected, with 3625 medical records requested.
    • An overall medical record retrieval rate of 47.9% was achieved.
    • Higher retrieval rates were observed from hospitals (54.7%) compared to physician offices (26.3%).

    Conclusions:

    • The national study achieved a modest medical record retrieval rate for validating claims-based AESI algorithms.
    • The described medical record retrieval procedures may enhance future retrieval success.
    • Accurate identification of AESI through claims data requires robust medical record validation.
