RESUMEN
OBJECTIVE: Previous studies have shown that treatment of obstructive sleep apnea (OSA) with positive airway pressure (PAP) therapy in patients with depression may improve depression symptoms and response to antidepressant therapy. We investigated the association between PAP therapy adherence, self-harm events, healthcare resource utilization (HCRU), and costs over 2 years in a national sample of patients with pre-existing depression and newly diagnosed comorbid OSA. METHODS: Administrative claims data were linked to objective PAP therapy usage. Inverse probability treatment weighting was used to compare outcomes over 2 years across PAP adherence levels. The predicted numbers of emergency room (ER) visits and hospitalizations by adherence level were assessed using risk-adjusted generalized linear models. RESULTS: 37,459 patients were included. Relative to non-adherent patients, consistently adherent patients had fewer self-harm events (0.04 vs 0.05, p < 0.001) after 1 year, and significantly (all p < 0.001) fewer ER visits (0.66 vs 0.86) and all-cause hospitalizations (0.13 vs 0.17), and lower total ($11,847 vs $11,955), inpatient hospitalization ($1634 vs $2274), and ER visit ($760 vs $1006) costs per patient in the second year of PAP therapy. Consistently adherent patients showed lower risk for hospitalizations and ER visits. LIMITATIONS: Using observational claims data, we were unable to assess clinical characteristics including sleep, sleepiness, and daytime symptoms, or important social determinants of health. We were limited in assessing care received outside of the included health plans. CONCLUSION: Consistent adherence to PAP therapy over 2 years was associated with improved HCRU outcomes for patients with pre-existing depression newly diagnosed with comorbid OSA.

AIMS: The aim of this study was to evaluate the impact of systemic lupus erythematosus (SLE) on the lives of patients in order to inform the development of a conceptual model. METHODS: Twenty-two participants with SLE (defined as meeting four of the 11 ACR criteria) were recruited for this study. Semi-structured, in-person interviews were conducted with each participant, exploring the symptoms experienced and the impact on the patient's life. Thematic analysis of interview transcripts was conducted in ATLAS.ti software to identify areas of impact and explore the interrelationships between concepts to inform the development of a conceptual model. RESULTS: Almost all participants were female (95%); the sample was diverse in terms of age (mean age of 45.5 years; age range of 20-60 years), ethnicity (59% black/African American) and disease duration. Commonly reported symptoms were pain, fatigue/tiredness and skin problems. Qualitative analysis revealed seven themes relating to the impact of SLE symptoms on patient's Health Related Quality of Life (HRQL): emotions, social, family and leisure activities, daily activities, cognition, appearance, employment activities and independence. The interrelationships between symptoms, impacts and symptom triggers are illustrated in a conceptual model. CONCLUSIONS: The conceptual model illustrates the wide-reaching impact of SLE symptoms on a patient's HRQL, and the potential broad impact of a treatment that improves SLE symptoms.
