Novice-performed point-of-care ultrasound for home-based imaging

Area of Science:

• Point-of-care ultrasound (POCUS)
• Medical imaging
• Healthcare technology

Background:

• Home-based healthcare is expanding.
• Patient-performed point-of-care ultrasound (POCUS) offers potential for remote monitoring.
• Lung ultrasound (LUS) is a key diagnostic tool.

Purpose of the Study:

• To evaluate if novice users can obtain interpretable, expert-quality lung ultrasound (LUS) images through self-scanning at home.
• To compare the quality and interpretability of LUS images obtained by novice users versus POCUS experts.

Main Methods:

• Adult volunteers without prior medical or POCUS training were recruited.
• Participants received minimal training and then performed self-scans of 8-zone LUS at home using a handheld POCUS device.
• Images were compared to LUS scans performed by POCUS experts, with both sets independently scored by blinded experts.

Main Results:

• No significant difference in image quality was found between novice and expert scans (p=0.09).
• Individual zone quality also showed no significant difference (p>0.05).
• Interpretability was similar, with both groups achieving a median of 7 interpretable zones out of 8 (p=0.42).

Conclusions:

• Novice users can successfully obtain interpretable, expert-quality LUS images with minimal training.
• Patient-performed LUS is a feasible option for outpatient home monitoring.
• This technology could enhance remote patient care and diagnostics.
