Although the popularity of unlicensed assistive personnel (UAP) models is evident by their implementation across the country, there has been very little scientifically based evaluation of their effectiveness. To facilitate better program evaluation, the authors review the current literature and outline a variety of data elements essential to effective UAP model evaluation. Major concepts that are addressed include program cost-effectiveness, customer satisfaction, patient outcomes, and evaluation of the success of both the training and implementation processes. Research questions that are pertinent to the model and need investigation also are presented. It is only through more thorough program evaluations that nurse executives can make informed decisions regarding the outcomes of care delivery restructuring efforts.
