Background

The OrthoMiDaS (Orthopedic Minimal Data Set) Episode of Care (OME) database was developed in an effort to advance orthopedic outcome measurements on a national scale. This study was designed to evaluate if the OME data capture system would increase the quality of data collected in the context of primary and revision total hip arthroplasty (THA) compared to conventional operative notes.

Methods

This study includes data from the first 100 primary THAs and 100 revision THAs performed by 15 surgeons at a single institution from January through April 2016. Surgeons prospectively entered procedural details into OME following surgery. The OME database and operative notes were compared to evaluate completion rates and agreement. Completion rates were compared using McNemar’s test (with continuity correction), while agreement was analyzed using Cohen’s kappa (κ) and concordance correlation coefficient.

Results

The OME database had significantly higher completion rates for 41% (39/96) of the variables. Proportion of data points that matched between the operative notes and OME data revealed that 54% (52/96) had a proportion agreement >0.90, and 79% (76/96) had a proportion agreement >0.80. In regard to measured agreement, 25% (24/96) of variables had almost perfect agreement, 29% (28/96) had substantial agreement, and 14% (13/96) had moderate agreement. Only 4% (4/96) had fair agreement, 8% (8/96) had slight agreement, and 6% (6/96) had poor agreement.

Conclusion

The OME data capture system is an efficient tool to document procedural details following THA. The system is user-friendly, comprehensive, and accurate. It has the potential to be a valuable tool for future orthopedic research.
