Objective:

To analyze the implementation fidelity of self-administered pulse oximetry and remote patient monitoring for high-risk COVID-19 patients in Honduras.

Approach:
  • Study Design: A retrospective fidelity of implementation analysis using Carroll’s Conceptual Framework for Implementation Fidelity.
  • Data Collection: Analysis of trial data, acceptability assessments, and implementation documentation.
Key Findings:
  • 98.9% coverage of eligible patients (1,821/1,841).
  • 97.7% completion of daily monitoring calls.
  • 97.7% utilization of pulse oximeters.
  • Participant satisfaction was 99.2%, with minimal withdrawal (0.3%) and loss to follow-up (2.0%).
  • Only 28% of participants sought additional care when referred for warning signs.
  • Unexpected benefits included reported positive impacts on participants’ mental health during isolation.
Interpretation:

The intervention achieved high fidelity in a lower-middle-income setting.

Limitations:
  • Limited generalizability due to the specific context of Honduras.
  • Only 28% of participants followed up on referrals for warning signs.
Conclusion:

The findings suggest that remote patient monitoring and self-administered pulse oximetry can enhance healthcare access during emergencies and routine circumstances.
