Flow chart showing positive airway pressure (PAP) therapy use during three distinct time periods. Flow chart showing positive airway pressure (PAP) therapy use during three distinct time periods. Initial = period immediately after the first or only re-titration; Transitional = period where subjects either used PAP but had no further re-titrations, used PAP and had one or more additional re-titrations, or were not using PAP but completed one or more additional re-titrations; Final = user status as of chart review end date. Final users (sum of all dark gray boxes) and Final non-users (sum of all dashed line boxes). *Of the 77 final non-users, 58 re-initiated PAP therapy either after initial or repeat re-titration studies but once again failed for various reasons (mask issues: 9, pressure intolerance: 9, lost to follow-up: 9, general adaptation problems: 7, money/insurance: 6, nasal congestion/allergy exacerbation: 4, no appreciable benefit: 4, claustrophobia: 3, physical side effects: 2, believed PAP was no longer needed: 2, focus on other health issues: 1). The remaining 19 subjects never re-initiated PAP. Of all 77 final PAP non-users, 21 pursued oral appliance therapy, and 9 elected to have surgery. Barry Krakow et al.
