INTRODUCTION: Nurse-managed health centers face increasing obstacles to financial viability. Efficient use of clinic resources and timely and appropriate patient care are necessary for sustainability. A registered nurse with adequate education and support can provide high-quality triage and advice in community-based practice sites. The purpose of this program evaluation was to examine the effect of a telephone advice nurse service on parent/caregiver satisfaction and access to care. METHODS: A quasi-experimental separate pre-post sample design study investigated parent/caregiver satisfaction with a telephone advice nurse in an urban pediatric nurse-managed health center. The clinic medical information system was used to retrieve client visit data prior to the service and in the first year of the program. RESULTS: Statistically significant differences were found on two items from the satisfaction with the advice nurse survey: the reason for calling (P < .05), and the importance of being involved in decision making (P < .05). DISCUSSION: A telephone advice nurse may increase both parent/caregiver and provider satisfaction and access to care.
