¹Workload variables adjusted for the employment period and weekly hours worked (1-40). Visits during each PS’s employment period were divided by the total number of hours worked, then multiplied by 40 to calculate adjusted values for both operationalizations of Reach and total number of services (Adoption) provided per a 40-h work week
