Compliance with continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea among privately paying patients- a cross sectional study

Background: To evaluate the compliance, benefits and side effects associated with continuous positive airway pressure (CPAP) therapy among Pakistani patients treated for obstructive sleep apnea (OSA) in private sector.Methods: Patients diagnosed to have OSA based on overnight study who were recommended for CPAP therapy, between 1998 and 2003, were evaluated by telephonic survey and review of hospital notes. Compliance, benefits and side effects associated with CPAP therapy were assessed.Results: Out of 135 patients who were prescribed CPAP therapy, 75 could be contacted. Sixty (80%) started using CPAP within one month of diagnosis and 46 (61%) continued to use it long-term (beyond one year). Compliance with CPAP therapy was associated with higher body mass index, higher Epworth sleepiness scale score, history of witnessed apnea, and reduction in daytime sleepiness with CPAP therapy. OSA severity as assessed by apnea-hypopnea index did not affect compliance with CPAP therapy. Use of anti-depressants and CPAP induced sleep disturbances were associated with poor compliance with CPAP therapy.CONCLUSIONS: Obesity, excessive daytime sleepiness, witnessed apnea and improvement of daytime symptoms following use of CPAP were predictors of improved compliance. Use of antidepressants and CPAP induced sleep disturbances were predictors of poor compliance

Consenso brasileiro de ronco e apneia do sono: aspectos de interesse aos ortodontistas Brazilian consensus of snoring and sleep apnea: aspects of interest for orthodontists

O objetivo deste artigo é explicitar o posicionamento das sociedades médicas que, reunidas, estabeleceram consenso sobre os parâmetros clínico-laboratoriais que envolvem os distúrbios respiratórios do sono, em especial o ronco e a síndrome da apneia obstrutiva do sono (SAOS). Os ortodontistas, que vêm ocupando gradativamente seu espaço em equipes multidisciplinares que atuam na área do sono humano, pouco conhecem sobre essa uniformização coordenada pela Associação Brasileira de Sono. Os trabalhos clínicos e as pesquisas científicas oriundos da Odontologia, e em particular da Ortodontia, também devem observar e seguir esses critérios de diagnóstico e tratamento estabelecidos pela comunidade médica brasileira.<br>The objective of this article is to clarify the positions of the medical societies that have worked together to establish a consensus regarding the clinical and laboratory parameters involved in sleep-disordered breathing, particularly snoring and obstructive sleep apnea syndrome (OSAS). Orthodontists have gradually come to take part in multidisciplinary teams that act in the area of human sleep, but few know about the uniformity coordinated by the Brazilian Association of Sleep. Clinical and scientific studies from the field of dentistry (particularly orthodontics) also must observe and follow these diagnosis and treatment criteria established by the Brazilian medical community
