Background:
Every year, more than 5 million patients seek medical care for chest pain.
Objective:
The goal of this study was to evaluate test utilization and outcomes of a nurse practitioner (NP)-based chest pain unit and compare results to data previously reported from our institution.
Design, Setting, And Participants:
The records from 814 consecutive patients with chest pain admitted to the NP-run unit were compared to the outcomes of 250 patients admitted to a separate hospitalist-run unit at a New York City hospital.
Results:
Forty-four percent of patients in the NP unit underwent stress myocardial perfusion imaging (MPI) as the primary diagnostic test (compared to 22% in the hospitalist unit, p < .0001). The average length of stay was shorter for patients in the NP unit (2.7 ± 3.6 days compared to 3.9 ± 3.4 days, p < .0001). Additionally, the 90-day readmission rate was less for patients in the NP unit (2.7% vs. 3.9%, p < .0006).
Conclusions:
An NP-run chest pain unit resulted in decreased length of stay and reduced readmission rates compared to a hospitalist-based unit.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
