In order to address the confounder of TBSA on burn outcomes, we sought to analyze our experience with the use of autologous skin cell suspensions (ASCS) in a cohort of subjects with hand burns whose TBSA totaled 20% or less. We hypothesized that the use of ASCS in conjunction with 2:1 meshed autograft for the treatment of hand burn injuries would provide comparable outcomes to hand burns treated with sheet or minimally meshed autograft alone. A retrospective review was conducted for all deep partial and full-Thickness hand burns treated with split-Thickness autograft (STAG) at our urban verified burn center between April 2018 and September 2020. The exclusion criterion was a TBSA greater than 20%. The cohorts were those subjects treated with ASCS in combination with STAG (ASCS(+)) vs those treated with STAG alone (ASCS(-)). All ASCS(+) subjects were treated with 2:1 meshed STAG and ASCS overspray while all ASCS(-) subjects had 1:1, piecrust, or unmeshed sheet graft alone. Outcomes measured included demographics, time to wound closure, proportion returning to work (RTW), and length of time to RTW. Mann-Whitney U test was used for comparisons of continuous variables and Fisher's exact test for categorical variables. Values are reported as medians and 25th and 75th interquartile ranges. Fifty-one subjects fit the study criteria (ASCS(+) n = 31, ASCS(-) n = 20). The ASCS(+) group was significantly older than the ASCS(-) cohort (44 [32-54] vs 32 years [27.5-37], P =. 009) with larger %TBSA burns (15% [9.5-17] vs 2% [1-4], P <. 0001) and larger size hand burns (190 [120-349.5] vs 126 cm2 [73.5-182], P =. 015). Comparable results were seen between ASCS(+) and ASCS(-), respectively, for time to wound closure (9 [7-13] vs 11.5 days [6.75-14], P =. 63), proportion RTW (61% vs 70%, P =. 56), and days for RTW among those returning (35 [28.5-57] vs 33 [20.25-59], P =. 52). The ASCS(+) group had two graft infections with no reoperations, while ASCS(-) had one infection with one reoperation. No subjects in either group had a dermal substitute placed. Despite being significantly older, having larger hand wounds, and larger overall wounds within the parameters of the study criteria, patients with 20% TBSA burns or smaller whose hand burns were treated with 2:1 mesh and ASCS overspray had comparable time to wound closure, proportion of RTW, and time to return to work as subjects treated with 1:1 or piecrust meshed STAG. Our group plans to follow this work with scar assessments for a more granular picture of pliability and reconstructive needs.
