Integration of point-of-care ultrasound in a nurse practitioner-led heart failure clinic.

BACKGROUND

Despite improved survival, one in five patients with heart failure (HF) is readmitted within 30 days of discharge. Assessing fluid status is challenging, with an estimated 50% accuracy when relying on physical examination alone. Pulmonary congestion is a risk factor for readmission and can manifest weeks before symptoms occur.

PURPOSE: To conduct a pilot study to assess for pleural effusion with point-of-care ultrasound (POCUS) and to evaluate inferior vena cava (IVC) noncollapsibility as a marker of volume status.

METHODS

A convenience sample of adults with HF ( n = 21) were seen in a nurse practitioner (NP)-led postdischarge clinic within 12 days of hospitalization. The setting was a large tertiary care hospital. Inclusion criteria were patients with an HF diagnosis and Medicare insurance. The NP measured IVC diameter, assessed for collapsibility, and examined pleural cavities using a VSCAN POCUS device. Data were analyzed descriptively.

RESULTS

Pleural effusions were identified in three (14.3%) patients with POCUS and referred for thoracentesis. Inferior vena cava was noncollapsible in 5 (23.8%) patients; each of these patients required intervention for volume overload.

CONCLUSIONS

Point-of-care ultrasound can be used by NPs to identify patients with pleural effusions who may benefit from thoracentesis. Inferior vena cava noncollapsibility may be a predictor for volume overload.

IMPLICATIONS: Point-of-care ultrasound equips NPs with an extra tool to effectively manage HF.
