PURPOSE: CPAP is the therapeutic modality of choice for the treatment of Obstructive Sleep Apnea. Regular use of CPAP is effective in improving polysomnographic variables and long term complications of OSA. The impact of CPAP therapy on the Quality of life of the OSA patient still remains unclear despite several studies.
METHODS: We assessed the Quality of life of 65 OSA patients using the Calgary sleep apnea quality of life index (SAQLI) on the morning following the polysomnography study. Forty five of these 65 diagnosed patients used CPAP regularly. After about 3 years of CPAP use patients were interviewed and subjected to the same Questionnaire again. Twenty two patients turned up for the interview and Paired t test was used to compare the Quality of life before and after treatment.
RESULTS: Of the 22 subjects (19 Males, 3 Females) who completed the study the mean age was 47.36 years (+10.48 years), height 164.86 cm (+8.29cm) and BMI (Body mass Index) was 28.69 (+6.25). Mean apnea-hypopnea index was 22.46+13.09. Mean scores of the four SAQLI domains Daily function, Social Interaction, Emotional and Symptoms were 3.20(+0.78), 3.67(+0.68), 3.79(+0.52) and 4.5(+0.77) before the CPAP and 3.42(+0.76), 3.71(+0.74), 3.92(+0.54) and 5.03(+0.82) after the CPAP. The total mean SAQLI score increased from 3.79 (+0.40) to 4.02(+0.41) after CPAP therapy.
CONCLUSIONS: Compared to the general population, patients with OSA had a lower Quality of life, which improved after 3 years of CPAP therapy. There was significant improvement in Daily function, Emotional and Symptoms domains of SAQLI as well as total SAQLI score.
CLINICAL IMPLICATIONS: CPAP not only ameliorates the symptoms of OSA but also improves Quality of Life also. It doesnt only prevent long term complications of OSA but improves overall wellbeing of patient.
