Proficiency based progression simulation training significantly reduces utility strikes: A prospective, randomized and blinded study

Objectives: We evaluated a simulation-based training curriculum with quantitatively defined performance benchmarks for utility workers location and excavation of utility services.
Background: Damaging buried utilities is associated with considerable safety risks to workers and substantial cost to employers.
Methods: In a prospective, randomized and blinded study we assessed the impact of Proficiency Based Progression (PBP) simulation training on the location and excavation of utility services work.
Results: PBP simulation training reduced performance errors (33%, p = 0.006) in comparison a standard trained group. When implemented across all workers in the same division there was a 35-61% reduction in utility strikes (p = 0.028) and an estimated cost saving of £116,000 – £2,175,000 in the 12 months (47,000 work hours) studied.
Conclusions: The magnitude of the training benefit of PBP simulation training in the utilities sector appears to be the same as it is in surgery, cardiology and procedure-based medicine.
Application: Quality-assured utility worker simulation training significantly reduces utility damage and associated costs.
