“…Various health care delivery models have been studied in the literature suggesting solutions to access challenges. Standardizing appointment slot lengths ( Huang, 2016a ), analyzing no-show rates with predictive overbooking ( Creps & Lotfi, 2017 ; Huang & Hanauer, 2014 , 2016 ; Reid et al, 2015 ), reviewing scheduling methods including open access scheduling ( Ansell et al, 2017 ; Cruz et al, 2018 ; Kopach et al, 2007 ; O'Connor et al, 2006 ; Stubbs et al, 2012 ), scheduling groups ( Huang, 2016b ), shared appointments ( Edelman et al, 2015 ; Jhagroo et al, 2016 ), appointment slot times ( Huang & Verduzco, 2015 ; Huang & Marcak, 2015 ; Qu et al, 2013 ), and appointment systems ( Vissers, 1979 ), have all been evaluated. Most studies have utilized simulation or analytical modeling to predict access outcomes ( Creps & Lotfi, 2017 ; Huang, 2016a , 2016b ; Huang & Hanauer, 2015 , 2016 ; Kopach et al, 2007 ; Qu et al, 2013 ; Reid et al, 2015 ; Vissers, 1979 ), with a paucity of case-specific reports.…”
