Validation of Emergency Nurse Practitioner Competencies: Patient Complexity and Clinical Decision Making.

Over the past 15 years, the emergency nurse practitioner has been recognized as a nursing specialty role with dedicated scope and standards of practice. However, a paucity of objective data exists to validate the actual practice of emergency nurse practitioners in the emergency care setting. The purpose of this pilot study was to describe the initial acuity of patients assigned to emergency nurse practitioners, actions, decisional complexity, and disposition decisions of advanced practice nurses as they function in emergency departments in a single system. This descriptive exploratory study used retrospective chart data to gain understanding. The most common Emergency Severity Index level seen by emergency nurse practitioners was Emergency Severity Index 3. Of 8513 encounters with Emergency Severity Index level data, 21% were triaged at Emergency Severity Index 2, 56% at Emergency Severity Index 3, 21% at Emergency Severity Index 4, and only 2% at Emergency Severity Index 5. Half of encounters resulted in a Current Procedural Terminology code of 99825 or higher and 94% were coded at 99824 or higher. There were a high percentage of admissions including intensive care unit admissions. Although descriptive, this study is highly illustrative of the broad scope of complex skills and clinical decision making required to perform as an advanced practice nurse in the emergency department. Further examination of education and training is warranted.
