Objective:
To compare two different methods of clinical outcomes prospective documentation after revision hip arthroplasty: external and internal.
Methods:
Chi-squared test, Fisher's exact test and binary logistic regression analyses were performed.
Results:
Eighty one patients experienced a complication (520 arthroplasties). A significant difference was found between the two documentation methods in the variable "hematoma and postoperative hemorrhage", and a significant reduction of the internally and externally documented "total complication rate". Furthermore, the "length of hospital stay" and "duration of operation" predicted independently the occurrence of complications.
Conclusion:
Further improvement of documentation methods is required to measure the perioperative morbidity.

Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
