SAMPAP Trial -Impact of a Novel Sleep Apnea Management Group Intervention on Positive Airway Pressure Adherence

To examine the impact of the sleep apnea management (SAM) group-based intervention on Positive Airway Pressure (PAP) adherence compared to a patient group managed by non-sleep medicine physicians (patients who follow usual care and are receptive to the SAM Clinic but do not participate in a SAM group) on changes from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence.

Greater than 4 hours average daily use is considered adherent.

To examine the impact of the sleep apnea management (SAM) group-based intervention on Positive Airway Pressure (PAP) adherence compared to a patient group managed by non-sleep medicine physicians (patients who follow usual care and are receptive to the SAM Clinic but do not participate in a SAM group) on changes from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence.

Greater than 70% usage of days used is considered adherent.

To examine and compare changes in patient reported outcomes daytime sleepiness between the SAM Clinic and the usual care arms from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence. To examine the correlation between changes in daytime sleepiness to changes in PAP adherence at each time point (secondary analyses).

The Epworth Sleepiness Scale (ESS) is an 8-question scale that measures subjective daytime sleep propensity. Each question is scored on a scale of 0-3, with a total score possible of 0-24. Greater scores indicate greater daytime sleep propensity, with a score of ≥10 indicating excessive daytime sleep propensity.

Investigators hypothesize that greater improvement in daytime sleepiness will be noted with the SAM clinic intervention compared to usual care.

To compare changes in patient reported outcomes depressive symptoms between the SAM Clinic and the usual care arms from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence. To examine the correlation between changes in depressive symptoms to changes in PAP adherence at each time point (secondary analyses). The Patient Health Questionnaire 9 (PHQ-9) is a self-administered survey that assesses each of the 9 DSM-IV criteria for depression in a separate question. Each question is scored from 0-3, with a total possible score of 0-27. Higher scores indicate greater severity of depressive symptoms; a score of 20-27 is indicative of severe depressive symptoms warranting active treatment, 15-19 moderately severe warranting active treatment, 10-14 moderate, 5-9 mild, and 0-4 none/minimal depressive symptoms.

Investigators hypothesize that greater improvement in depressive symptoms will be noted with the SAM clinic intervention compared to usual care.

To compare changes in patient reported outcomes global health between the SAM Clinic and the usual care arms from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence. To examine the correlation between changes in global health to changes in PAP adherence at each time point (secondary analyses). The PROMIS Global Health (10 questions) short form measures health. Higher score indicate greater perceived health. The raw sum score is rescaled by a t-score into a standardized score, where a standard score of 50 is the general population average (with a standard deviation of 10). If not all questions were answered, a raw score can be calculated (and later standardized) from the following formula: (Score sum of questions answered * number of questions on the form) ÷Number of questions answered.

Investigators hypothesize that greater improvement in global health will be noted with the SAM clinic intervention compared to usual care.

To compare changes in patient reported outcomes in fatigue between the SAM Clinic and the usual care arms from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence. To examine the correlation between changes in fatigue to changes in PAP adherence at each time point (secondary analyses). The PROMIS Fatigue (8 questions) short form measures fatigue. Higher score indicate greater perceived fatigue. The raw sum score is rescaled by a t-score into a standardized score, where a standard score of 50 is the general population average (with a standard deviation of 10). If not all questions were answered, a raw score can be calculated (and later standardized) from the following formula: (Score sum of questions answered * number of questions on the form) ÷Number of questions answered.

Investigators hypothesize that greater improvement in fatigue will be noted with the SAM clinic intervention compared to usual care.

Compare changes in patient reported outcomes in sleep impairment between the SAM Clinic and the usual care arms from baseline to 1 and 3 months in those with moderate to severe OSA with suboptimal PAP adherence. To examine the correlation between changes in sleep impairment to changes in PAP adherence at each time point (secondary analyses). The PROMIS Sleep Related Impairment form measures sleep impairment. Higher score indicate greater perceived impairment. The raw sum score is rescaled by a t-score into a standardized score, where a standard score of 50 is the general population average (with a standard deviation of 10). If not all questions were answered, a raw score can be calculated (and later standardized) from the following formula: (Score sum of questions answered * number of questions on the form) ÷Number of questions answered.

Investigators hypothesize that greater improvement in sleep impairment will be noted with the SAM clinic intervention compared to usual care.

Examine the impact of the SAM Clinic on changes in barriers to PAP adherence compared to usual care from baseline contact to 3 months in those with moderate to severe OSA with suboptimal PAP adherence.

The Barriers questionnaire is a 12-question scale that measures subjective barriers to using a PAP machine. Each question is scored on a scale of 0-1, with a total score possible of 0-12. Greater scores indicate greater difficulty with wearing a PAP machine. Each yes answer can be addressed to improve the patient's use of the PAP.

Investigators hypothesize that the SAM Clinic intervention will be able to address PAP barriers more effectively compared to usual care. This questionnaire is in the yes/no format. This questionnaire is in the survey that will be completed by the patient.
