Does combining ExciteOSA with Positive Airway Pressure (PAP) therapy improve outcomes over PAP therapy alone for patients with Obstructive Sleep Apnea (OSA)?

Combining ExciteOSA with PAP Therapy for Obstructive Sleep Apnea

There is no evidence available to support combining ExciteOSA with PAP therapy, and current guidelines do not address this combination; therefore, PAP therapy alone remains the evidence-based standard of care for OSA treatment.

Current Evidence Base for PAP Therapy

The American Academy of Sleep Medicine strongly recommends PAP therapy as first-line treatment for adults with OSA and excessive sleepiness, based on high-quality evidence demonstrating clinically significant improvements in sleepiness 1. PAP therapy also provides conditional benefits for patients with impaired sleep-related quality of life and comorbid hypertension 1.

Absence of Combination Therapy Evidence

No studies in the provided evidence base evaluate ExciteOSA as an adjunct to PAP therapy. The 2019 AASM guidelines comprehensively reviewed interventions to augment PAP therapy outcomes, including 1:

• Educational interventions (strongly recommended prior to PAP initiation)
• Behavioral and troubleshooting interventions (conditionally recommended during initial PAP period)
• Telemonitoring-guided interventions (conditionally recommended)
• Alternative PAP modes (APAP, BPAP)

ExciteOSA is notably absent from these evidence-based adjunctive strategies.

Proven Strategies to Optimize PAP Outcomes

If the goal is to improve outcomes beyond PAP therapy alone, the following evidence-based interventions should be implemented 1:

Pre-Initiation Phase

• Educational interventions focusing on OSA pathophysiology, downstream consequences of untreated OSA, PAP mechanism of action, and potential benefits (STRONG recommendation) 1

Initial Treatment Phase

• Behavioral interventions using cognitive behavioral therapy or motivational enhancement strategies (CONDITIONAL recommendation) 1
• Troubleshooting interventions with close patient communication to identify and solve PAP-related problems early (CONDITIONAL recommendation) 1
• Telemonitoring-guided interventions to remotely monitor PAP parameters and trigger early interventions, which demonstrated a clinically significant improvement in adherence (CONDITIONAL recommendation) 1

Device Optimization

• Consider heated humidification to reduce nasal dryness and improve adherence, particularly in patients with nasal congestion 2
• Ensure proper mask interface selection and fitting to minimize leaks and maximize comfort 2
• Use CPAP or APAP as first-line therapy (equivalent efficacy), reserving BPAP for specific indications such as pressure intolerance >15-20 cm H₂O 1, 3

Critical Follow-Up Requirements

Adequate follow-up with objective monitoring is essential and non-negotiable 1. This includes:

• Close monitoring in initial weeks to months after PAP initiation, as early adherence predicts long-term adherence 1
• Objective PAP usage data monitoring to complement patient self-reporting (patients typically overestimate adherence) 1
• Yearly evaluation by trained healthcare providers for adherent patients with sustained symptom resolution 1
• More frequent follow-up for patients with persistent complaints or poor adherence 1

Clinical Outcomes with Proven Interventions

Studies demonstrate that PAP adherence is associated with significant improvements in patient-centered outcomes 4, 5:

• 57% decrease in hospitalizations and 36% decrease in emergency room visits in adherent patients with heart failure and OSA 4
• Lower total healthcare costs ($12,732 vs $15,610) in adherent versus non-adherent patients 4
• Fewer self-harm events and reduced healthcare resource utilization in patients with depression and comorbid OSA who maintain PAP adherence 5

Important Caveats

The absence of evidence for ExciteOSA as a PAP adjunct means its safety and efficacy in combination therapy are unknown. Adding unproven interventions may 6:

• Increase treatment complexity and cost without demonstrated benefit
• Potentially reduce adherence to the proven PAP therapy
• Delay implementation of evidence-based adherence strategies

Focus clinical efforts on the proven interventions outlined above rather than unvalidated combination approaches.
