Evaluation of the efficacy of a dedicated table to improve CPAP adherence in children: a pilot study.

Only a few studies have addressed strategies to improve continuous positive airway pressure (CPAP) adherence in children with obstructive sleep apnea. The aim of our study was to assess the efficacy of a table based on token economy to improve CPAP adherence. A table was proposed to children nonadherent to CPAP (<3 h per night of CPAP use), eight days after CPAP initiation (D8). The child has to fill the table on a daily basis with green (I used my CPAP this night) or red (I did not use my CPAP) tokens. Objectives of CPAP use and rewards were decided between the child and their parents. An assessment of CPAP adherence was performed one month after initiation of table filling (M1) and compared to CPAP adherence at D8, and to data of adherent children. Data of six nonadherent and nine adherent children were gathered (age 5 ± 5 vs. 5 ± 3 years, p = 0.953; apnea-hypopnea index 20 ± 15 vs. 25 ± 16 events/h, p = 0.550, respectively). Mean CPAP adherence at D8 was 4.7 ± 1.6 nights/wk and 1h00 ± 0h33 in the nonadherent children, vs. 6.9 ± 0.4 nights/wk and 7h16 ± 1h51 in the adherent group (p < 0.01). The mean number of nights per week at M1 was 6.4 ± 0.6 nights in nonadherent children (p = 0.086), and was equivalent to that in adherent children (6.8 ± 0.6 nights, p = 0.126). Mean adherence at M1 increased to 4h31 ± 1h12 in non-adherent children (p < 0.001), but was still lower when compared to that in adherent children (7h27 ± 2h00, p = 0.007). The study findings imply that use of a simple table by a child appears to be effective in improving CPAP adherence at one month.
