ROYAL COLLEGE OF OPHTHALMOLOGISTS' NATIONAL DATABASE STUDY OF VITREORETINAL SURGERY: Report 7, Intersurgeon Variations in Primary Rhegmatogenous Retinal Detachment Failure.

Background/purpose: To audit variations in primary rhegmatogenous retinal detachment (RD) anatomical failure rates between surgeons, grades of surgeons, and techniques of RD surgery.

Methods: Clinical data of a total of 5,857 eyes undergoing primary RD surgery, from 2000 to 2013 were retrospectively extracted from 15 centers using the same commercially available electronic medical record system, from three vitreoretinal units using an in-house electronic medical record, and from the British and Eire Association of Vitreoretinal Surgeons online registry.

Results: The 5,857 primary RD operations were performed by 117 surgeons: 3,349 (57.2%) by consultants, 520 (8.9%) by independent nonconsultants, and 1,988 (33.9%) by trainees. Surgery comprised pars plana vitrectomy for 4,666 (79.7%) operations, scleral buckle for 815 (13.9%), and pars plana vitrectomy + scleral buckle for 376 (6.4%). The RD reoperation rate at 6 months after primary surgery was 13.9% (725/5,202) and did not differ significantly between consultants and trainees (P = 0.382). For surgeons contributing ≥50 cases, the mean (range) reoperation rates were 13.1% (6.7%-26.8%), 15.1% (11.3%-18.2%), and 15.3% (9.4%-22.1%) for consultants, independent nonconsultants, and trainee surgeons, respectively. The scleral buckle failure rate was not significantly different from pars plana vitrectomy (P = 0.095). Data were not adjusted for case-mix complexity.

Conclusion: The grades of surgeons and the technique of surgery were not associated with a significant difference in primary unadjusted RD failure rates.
