Impact of a Laser Service Line for Burn Scar on a Dedicated Burn OR’s Flow and Productivity

: Our group began performing erbium-YAG 2940 wavelength fractional resurfacing of burn scar in our burn center's dedicated burn operating room (OR) in January 2016. The impact of these procedures on the performance of a mature, dedicated burn OR is unknown. All burn OR cases performed between January 1, 2015 and December 31, 2015 served as a pre-laser (PRE-LSR) historical control. A postintervention cohort of laser-only cases (LSR) performed between January 1, 2016 and August 17, 2016 was then identified. PRE-LSR and LSR cases were retrospectively reviewed for OR component times, and work relative value units (wRVU) billed. A total of 628 burn OR cases were done in 2015 (PRE-LSR), while 488 burn OR cases were done between January 1 and August 17, 2016. Of these 488, 59 cases were LSR (12.1%). Calculated on a monthly basis, significantly more cases were done per day in the LSR era (2.2 ± 0.4 cases/d) than PRE-LSR (1.6 ± 2.0 cases/d; P < .0001). The LSR group was significantly shorter than the PRE-LSR group for all OR component times (induction, prep, and procedure all P < .0001; transport out, P = .01; room turnover, P = .004). Aggregate OR component time was 79.2 ± 33.4 minutes for LSR and 157.5 ± 65.0 minutes for PRE-LSR (P < .0001). LSR yielded 6.9 ± 3.2 wRVU/h, while PRE-LSR generated 12.2 ± 8.9 wRVU/h (P < .0001). Despite significantly shorter OR component times and more cases being done per day, laser treatment of burn scar using a single 17108 Current Procedural Terminology code cuts wRVUs generated per hour in a mature burn OR roughly in half.
