The classification of sleep state in preterm infants, particularly in distinguishing between active sleep (AS) and quiet sleep (QS), has been investigated using cardiorespiratory information such as electrocardiography (ECG) and respiratory signals. However, accurately differentiating between AS and wake remains challenging; therefore, there is a pressing need to include additional information to further enhance the classification performance. To address the challenge, this study explores the effectiveness of incorporating video-based actigraphy analysis alongside cardiorespiratory signals for classifying the sleep states of preterm infants. The study enrolled eight preterm infants, and a total of 91 features were extracted from ECG, respiratory signals, and video-based actigraphy. By employing an extremely randomized trees (ET) algorithm and leave-one-subject-out cross-validation, a kappa score of 0.33 was achieved for the classification of AS, QS, and wake using cardiorespiratory features only. The kappa score significantly improved to 0.39 when incorporating eight video-based actigraphy features. Furthermore, the classification performance of AS and wake also improved, showing a kappa score increase of 0.21. These suggest that combining video-based actigraphy with cardiorespiratory signals can potentially enhance the performance of sleep-state classification in preterm infants. In addition, we highlighted the distinct strengths and limitations of video-based actigraphy and cardiorespiratory data in classifying specific sleep states.

Background: It is important to provide the necessary sleep for the growth of preterm infants in the neonatal intensive care unit. The purpose of this study was to determine the effect of 3-stair positioning pillows (TSPPs) developed for preterm infants with postnatal age 28 to 35 weeks on physiologic parameters and sleep-wakefulness status. Methods: This research was conducted as a randomized controlled experimental study. The CONSORT flowchart was used in the implementation of the randomized controlled trial. The preterm infants in the experimental group were placed in the prone position with TSPPs, whereas the preterm infants in the control group were followed in the routine prone position given in the neonatal intensive care unit. Preterm infants were followed for a total of 3 hours. Results: The sample of the study consisted of 60 preterm infants (experiment group = 30; control group = 30) who were hospitalized in the neonatal intensive care unit and met the selection criteria. Compared with the infants in the control group, the preterm infants in the experimental group were determined to have significantly lower heart rates, higher oxygen saturations, lower respiratory rates, longer sleep durations, and shorter wakefulness times (P < .001). Conclusion: It was found that positioning preterm infants using TSPP had positive effects on physiological parameters (heart rate, oxygen saturation, and respiratory rate) and sleep-wakefulness status in favor of the experimental group. Implications for Practice: It is recommended to use a TSPP that supports the prone position to improve the physiologic parameters and sleep-wakefulness status of preterm infants in the neonatal intensive care unit. Larger studies need to be conducted utilizing longer follow-up protocols. Examining the effectiveness of TSPPs with different positioning materials in preterm infants is needed.
