Insights
Actigraphy is a promising tool for identifying sleep issues in children with severe illnesses and neurological impairments receiving palliative care. This method showed similar results to polysomnography for sleep metrics.
Area of Science:
- Pediatric Sleep Medicine
- Neurology
- Palliative Care
Background:
- Assessing sleep patterns in children with life-limiting conditions and severe neurological impairment is challenging.
- The utility of actigraphy, a non-invasive sleep monitoring technique, in this specific population remains unclear.
- Benchmarking actigraphy against polysomnography (PSG), the gold standard, is crucial for validating its use.
Purpose of the Study:
- To evaluate the accuracy of actigraphy in measuring sleep parameters in children receiving pediatric palliative care (PPC).
- To compare actigraphy data with polysomnography (PSG) findings in a cohort of N=8 PPC patients.
- To determine the applicability of actigraphy for detecting sleep disturbances in this complex pediatric group.
Main Methods:
- Actigraphy devices were used concurrently with one-night polysomnography (PSG) in a sleep laboratory setting.
- Data from N=8 pediatric palliative care patients were collected and analyzed.
- Bland-Altman plots were employed to assess the agreement between actigraphy and PSG for various sleep metrics, including sleep onset, offset, wake after sleep onset (WASO), total sleep time (TST), and sleep efficiency.
Main Results:
- PSG identified sleep stage 2 as the predominant sleep stage (46.6%) and revealed frequent central apneas (28.7%) and irregular hypopneas (14.5%).
- Actigraphy demonstrated comparable results to PSG for sleep onset, sleep offset, WASO, TST, and sleep efficiency.
- Actigraphy tended to slightly overestimate TST and sleep efficiency, while underestimating other parameters; Actiwatch 2 at low and medium sensitivity settings showed the best agreement with PSG.
Conclusions:
- Actigraphy appears to be a viable and promising method for monitoring sleep in children with severe illnesses and neurological impairments.
- The findings support the use of actigraphy as a practical tool for identifying sleep problems in pediatric palliative care settings.
- Further research can refine actigraphy protocols for this vulnerable population.
Abstract:
In children with life-limiting conditions and severe neurological impairment receiving pediatric palliative care (PPC), the degree to which actigraphy generates meaningful sleep data is uncertain. Benchmarked against the gold standard polysomnography (PSG), the applicability of actigraphy in this complex population was to be assessed. An actigraph was placed on N = 8 PPC patients during one-night polysomnography measurement in a pediatric tertiary care hospital's sleep laboratory. Patient characteristics, sleep phase data, and respiratory abnormalities are presented descriptively. Bland-Altman plots evaluated actigraphy's validity regarding sleep onset, sleep offset, wake after sleep onset (WASO), number of wake phases, total sleep time (TST) and sleep efficiency compared to PSG. PSG revealed that children spent most of their time in sleep stage 2 (46.6%) and most frequently showed central apnea (28.7%) and irregular hypopnea (14.5%). Bland-Altman plots showed that actigraphy and PSG gave similar findings for sleep onset, sleep offset, wake after sleep onset (WASO), total sleep time (TST) and sleep efficiency. Actigraphy slightly overestimated TST and sleep efficiency while underestimating all other parameters. Generally, the Actiwatch 2 low and medium sensitivity levels showed the best approximation to the PSG values. Actigraphy seems to be a promising method for detecting sleep problems in severely ill children.
