Blinding data collectors can enhance construct validity. External validity can also be increased through the implementation of more RCTs. Topics should be expanded to include long-term patient outcomes, cost-effectiveness, staffing, funding, and adherence to the HELP model. Cost-effectiveness and funding particularly require future examination. It has not been shown that hospitals can all afford a HELP coordinator fully implement the HELP protocol. The expansion of research to include these topics can increase the strength of the clinical outcomes of HELP. It also can assist hospitals to understand the necessary staffing and funding to implement HELP. Future research can strengthen HELP's evidence and assist in the implementation of HELP.
