Original ArticleContinuous positive airway pressure and noninvasive ventilation adherence in children
Introduction
Noninvasive continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) are effective treatments for obstructive sleep apnea (OSA) and nocturnal hypoventilation, respectively. By maintaining a constant positive pressure in the airways during the whole breathing cycle, CPAP is able to correct the complete (apnea) or partial (hypopnea) closure of the upper airways during sleep. By delivering a positive pressure or a volume during the patient’s inspiration, NIV is able to reverse nocturnal alveolar hypoventilation in patients who experience hypoventilation during sleep, such as patients with restrictive or neuromuscular disease or patients with lung disease. Adherence to these treatments is essential for their efficacy. Indeed, a study performed in 52 children with OSA showed a correlation between CPAP use and the improvement in daytime sleepiness assessed by the change in the Epworth Sleepiness Scale [1]. Moreover, regular overnight use of NIV treatment has been shown to correct nocturnal and daytime gas exchange in children with neuromuscular disease [2], [3]. However, the minimal hours of CPAP or NIV use for an optimal effectiveness in children is not known and may vary by the age of the patient and by the type and the severity of the underlying disease.
Adherence has to be assessed on objective data. Indeed, initial studies reported adherence to be high when using self-reported or parent-reported measures of CPAP use [4], [5]. However, adherence proved to be lower when objective adherence was gathered from the ventilators [6]. Nowadays, objective adherence is accessible from most of the ventilators not only as an hour meter recording (i.e., when the ventilator is switched on), but also from built-in software that delivers a detailed report of all the parameters of the ventilator, such as airway pressure, leaks, and several respiratory parameters, thus allowing a more comprehensive approach of observing the patient’s sleep with CPAP or NIV treatment [7], [8].
Numerous factors, such as age [9], [10], type of interface [9], and the association of an educational program may influence treatment adherence [11]. With the rapid increase of children needing CPAP or NIV treatment [12], together with continuous improvements in ventilators and interfaces, adherence may change in children. The primary objective of our study was to assess the objective compliance in children treated with long-term CPAP or NIV treatment at home with a standardized medical follow-up in a tertiary pediatric NIV unit. The secondary objective was to determine the variables significantly associated with CPAP/NIV adherence.

Subjects
Between June 2012 and January 2013, data from all consecutive patients older than the age of 2 years, who were receiving CPAP or NIV treatment at home for at least 1 month and who were hospitalized for a routine CPAP/NIV overnight control in the hospital, were analyzed. Nocturnal gas exchange with CPAP/NIV was recorded in all the patients. Demographic data and ventilator and interface equipment were obtained. Patients were classified in three groups according to the underlying disease: OSA,
Results
The data of 62 patients (ages, 2–18 years) were analyzed (Table 1). The majority of the patients had OSA (82%). Most patients (61%) were ventilated with a nasal mask; these patients were significantly younger than the patients ventilated with a facial mask or nasal cannula (P < .001).
Mean objective adherence was extremely high with a mean use of 8:17 ± 2:30 h:min per night and 72% of the patients using their CPAP or NIV >8 h:min per night (Table 1). The mean number of nights of CPAP or NIV use during
Discussion
Our study shows that objective adherence to home CPAP and NIV use was extremely high in children in whom CPAP or NIV treatment was initiated in a pediatric NIV unit. Treatment adherence was not affected by the underlying disease, the age of the patient, the type of ventilation (CPAP or NIV), the type of interface, the duration of CPAP or NIV, or the efficacy of treatment assessed by nocturnal gas exchange. This finding may be explained by the high level of adherence, which is close to the
Conclusion
Our observational study revealed a high level of adherence in a large group of children older than the age of 2 years who were treated at home with long-term CPAP or NIV, with a mean nighttime use close to that of the normal sleep duration. These adequate results underline the importance of a dedicated pediatric NIV unit for the initiation and follow-up of these patients. This availability provides strong, positive, and continuous support of the patient and his or her family by the expert team

2022, Neuromuscular DisordersCitation Excerpt :NIV/CPAP was initiated on “other criteria” in 20% of the patients, comprising: abnormal blood gases, clinical criteria, the relay of invasive ventilation and/or the impossibility to wean the patient from NIV/CPAP initiated during a respiratory exacerbation, prior to elective surgery [22], restrictive lung disease on lung function tests, or thoracic deformity. The mean objective adherence was good as reported by other French studies [23–25]. This may be explained by the therapeutic education of the patients and caregivers and the expertise of the centres, associated with a well organised national home care provider network.
