The RDC (retrospective data collection) Database is composed of administrative data from CHEER sites. It is the foundation for selecting sites to participate in studies or initiatives that fit a site’s practice profile. Thought leadership and design of the RDC is guided by the AAO-HNSF Task Force for Practice-based Research. RDC 1 was CHEER’s first data harvest and has been the basis for four publications and cited in numerous others. It is the largest database of otolaryngology data collected by and for otolaryngologists.
The RDC project was completed in 22 sites. Each site submitted one calendar year of patient de-identified data. The RDC database currently holds more than 261,484 unique patients with 650,716 unique encounters with ICD9, demographic, and CPT codes.
Value of the RDC
The RDC has proven its value by:
- Matching sites to initiatives
- Providing grant sample size feasibility
- Pilot data for investigators
- A big data research resource
An update of the site descriptor database (RDC2) is under way through a combined approach of traditional data capture and electronic sharing activities.
CHEER Applied is launching a collaborative project with DARTNet Institute to develop capability to extract data elements from the clinical record for research and physician quality reporting. If you are using one of a number of common EHRs (19 KB PDF), you could be eligible to receive full support for this powerful demonstration project. A limited number of sites will be selected for this trial.
DARTNet technology is HIPAA compliant and will ensure that the data extracted is analyzed and reported accurately to YOU. The aggregate data collected in this initiative will be used to refine the data extraction specifications and processes before being rolled out as a fee based service to other practices. Early adopter sites will be fully supported for a period of 3 years. Fees are expected to be very reasonable, based upon the complexity and frequency of the reporting each practice elects.
With the update, the AAO-HNSF Task Force on Practice-based Research will provide input on additional fields they advise are feasible to extract for the RDCs and value-added.
The current fields are:
- Patient Identifier (scrambled but unique so a patient can be followed)
- Encounter ID
- Month of visit
- Year of visit
- Age at time of visit
- Primary Dx
- All available secondary Dx
- Primary Px
- All available secondary Px
Through the AAO-HNSF Task Force on Practice-based Research, several manuscripts were prepared. RDC manuscripts for the feature issue of the Academy’s Journal include:
- Thyroid (submitted)
- Menieres (submitted)
- Tonsillectomy/bleed rates (close to final)
- Vestibular Testing (analyses complete; being written)
Manuscripts focus on practice variation and patterns. All task force members are listed as co-authors.
