Surveillance was consistently the predominant APN function across the five different patient
groups, and health teaching, guidance, and counseling was the next most frequent APN
function in four of the five groups. In all five groups, treatments and procedures accounted
for less than 1% of total APN interventions. In the original findings from the randomized
trials, the APN-followed participants in each of the five study groups had consistently fewer
rehospitalizations compared to the controls. Although not statistically significant in several of the studies, consistent differences in health care cost savings were documented. The
APN-followed participants, if rehospitalized, were rehospitalized for fewer hospital days at
less cost. Documentation of the amount of APN surveillance, and early detection of health
problems, plus focused health teaching of patients regarding prevention and early detection
of problems specific to these patient groups provides evidence to help explain the reduced
rehospitalizations and reduced health care costs. These study findings provide strong support
for the APNs' well-developed assessment skills and targeted, effective patient teaching in
reducing morbidity and health care costs.
