This study examined the association of potentially modifiable characteristics, including treatment delay, with KC defect size after Mohs micrographic surgery (MMS). A stratified random sample of patients treated for KC with MMS were selected for telephone interview. Two hundred and nineteen interviews were completed (refusal rate 24% ). Regression models were used to examine the predictors to defect size and delay. Anatomic site, age, histology, and gender predicted defect size(R2 =0.39) and were used as control variables. Selfreported delay between initial physician examination and MMS predicted defect size (P=0.0004), with greater than 1 y delay being associated with a doubling of defect size (adjusted odds ratio (OR) 2.0; 95% confidence interval (CI) 1.3- 3.1). Delays of this duration were associated with initial examination by a primary provider (unadjusted OR 3.9; 95% CI 1.7- 8.8), misdiagnosis (unadjusted OR 6.8; 95% CI 2.5- 18.7), being treated without biopsy (unadjusted OR 23.3; 95% CI 6.5- 83.7), and multiple surgical removals (unadjusted OR 6.2; 95% CI 2.5- 15.5). All but provider specialty were independent predictors of delay. Attention to processes of care delivery for KC may have a greater impact on morbidity than efforts are earlier detection by the public.展开更多
