Oral Feeding Readiness Assessment Tools for Preterm Infants

Due to their underdeveloped physiological maturity, preterm infants often face challenges related to sucking, breathing, and swallowing coordination during initial feeding. This lack of coordination may lead to episodes of apnea and choking, resulting in unstable vital signs. Preterm infants with this issue must gradually learn oral feeding skills appropriate to their developmental stage. Registered nurses play a critical role in assessing the right time to transition from tube to oral feeding and in providing a safe and positive oral feeding experience. In this article, three validated assessment tools for feeding premature infants are introduced, accompanied by clinical research data demonstrating their use in clinical practice. These three tools include: (1) the Neonatal Oral Motor Assessment Scale, which is applied to evaluate oral motor skills using observations of nonnutritive sucking and the sucking state during the two minutes before feeding; (2) the Premature Oral Feeding Readiness Assessment Scale, which is used to assess readiness for oral feeding in preterm infants; and (3) the Early Feeding Skills assessment, which is used to evaluate the oral feeding skills of preterm infants. These tools aid nurses in helping preterm infants achieve independent oral feeding, facilitating earlier discharge and return to home. The clinical implications and effectiveness of these tools are also discussed to provide to nurses the means and confidence necessary to apply them appropriately in clinical settings.

Turkish adaptation of the Neonatal Eating Assessment Tool-Bottle-Feeding in preterm infants discharged to home.

Preterm infants often continue to have feeding difficulties after hospital discharge. Parental use of assessment tools and collaboration with health professionals are important for the early diagnosis of postdischarge feeding difficulties. This methodological study examined the validity and reliability of the Turkish version of the Neonatal Eating Assessment Tool (NeoEAT)-Bottle-feeding in postdischarge preterm infants in Türkiye. A Turkish version of the NeoEAT-Bottle-feeding was developed and applied to 321 mothers of preterm infants younger than 7 months of corrected age between August 2021 and December 2022. Cronbach's alpha, exploratory factor, confirmatory factor, item-total correlation, test-retest, and known-groups validity analyses were performed. The Turkish NeoEAT-Bottle-feeding has 60 items in five factors explaining 55.785% of the total variance. Exploratory factor analysis indicated that the item factor loading ranged from 0.320 to 0.792. The known-group validity analysis confirmed that preterm infants with diagnosed feeding problems had higher total and subscale scores than those without (p = 0.001). The Cronbach's alpha (α) of the entire scale was 0.96. The item-total correlation coefficients were between 0.31 and 0.77 (p = 0.001). There was excellent agreement between test values and retest values obtained after a 2-week interval (intraclass correlation coefficient: 0.930-1.000). The Turkish NeoEAT-Bottle-feeding was shown to be a reliable and valid parent-reported assessment tool for oral feeding skills and difficulties after neonatal intensive care unit discharge in bottle-fed preterm infants younger than 7 months of corrected age. Healthcare professionals can use this assessment tool during the initial evaluation of risk factors contributing to problematic feeding and to determine the effectiveness of planned interventions in preterm infants.

A parent-administered sensorimotor intervention for oral feeding in infants born preterm: A randomized clinical study.

To evaluate the effect of a parent-administered sensorimotor intervention (PASI) program on developmental outcomes of infants born preterm during their stay in the neonatal intensive care unit (NICU). A randomized clinical study was conducted with 94 infants (mean gestational age 31 weeks [SD 2.2 weeks]; 1658 g [SD 478 g]; 49 males, 45 females) initially enrolled and randomly assigned to an experimental or a control group. Infants in the experimental group received a PASI, consisting of tactile input to oral structures, trunk/limbs, and non-nutritive sucking for 15 minutes, once a day, for 10 days. Infants in the control group received standard care. Outcomes included attainment of complete oral feeds, occurrence of direct breastfeeding at hospital discharge, and motor function assessed using the Test of Infant Motor Performance (TIMP). A total of 80 infants completed the study. Infants in the experimental group achieved complete oral feeds sooner (11.9 [SD 4.3] vs 15.3 [SD 6.5] days, p = 0.013), and a greater number of them received direct breastfeeds (22 vs 12, p = 0.010) than controls. Infants in both groups had equivalent motor functions scores on the TIMP (46.9 [SD 4.8], 46.8 [SD 8.4], p = 0.961). A PASI program may enhance an infant's oral feeding skills. These findings provide evidence to advocate for the institution of PASI in NICUs.

A Scoping Review on the Effects of Kinesio Taping on Oropharyngeal Function Related to Swallowing and Feeding.

Following the expansion of interdisciplinary communication among rehabilitative service providers, new techniques have been introduced for treating swallowing disorders. Kinesio taping (KT) is one of the recently noticed techniques in the rehabilitation of swallowing and feeding disorders. Given the novelty of this technique in research and practice, the present scoping review aimed to summarize the available evidence on the effects of KT on the oropharyngeal function related to swallowing, and to identify current knowledge gaps to guide future studies. The initial comprehensive search was conducted in the six databases in November 2022 and then was updated in June 2023. Studies were independently reviewed by two authors to exclude all types of reviews and study protocols, studies published only in an abstract form and also studies that used KT for improving voice and dysarthria symptoms. The methodology of the included studies was also critically appraised using Joanna Briggs Institute (JBI) standard tools by two authors. The results of the studies were categorized and reported based on their overall objectives. In final analysis, 21 articles were described. Study designs ranged from randomized control trials (RCTs) to the case reports. The effects of KT had been investigated on drooling, oral feeding skills of infants, immediate activation of swallowing muscles, and management of dysphagia in patients with stroke or cerebral palsy (CP). Although innovative approaches to use KT as a therapeutic method in swallowing disorders have been investigated in the studies, there are many methodological limitations that affected validity of the results. In general, it seems there is not enough evidence to add KT to the usual management of feeding and swallowing disorders yet. Further studies, therefore, are required to achieve more accurate conclusions in each of the objectives summarized in this study.

The transition from tube feeding to oral feeding algorithm in preterm infants: case-control study

BackgroundOral feeding is a complex sensorimotor process influenced by many variables, making it challenging for healthcare providers to introduce and manage it. Feeding practice guided by tradition or a trial-and-error approach may be inconsistent and potentially delay the progression of oral feeding skills.AimTo apply a new feeding approach that assesses early oral feeding independence skills of preterm infants in the neonatal intensive care unit (NICU). To prove its effectiveness, compare two approaches of oral feeding progression based on clinical outcomes in preterm infants, the traditional approach used in the NICU of Mansoura University Children Hospital (MUCH) versus the newly applied approach.MethodsA quasi-experimental, exploratory, and analytical design was employed using two groups, control and intervention groups, with 40 infants for the first group and 41 infants for the second one. The first group (the control) was done first and included observation of the standard practice in the NICU of MUCH for preterm oral feeding, in which oral feeding was dependent on post-menstrual age (PMA) and weight for four months. The second group (the intervention) included early progression to oral feeding depending on early assessment of Oral Feeding Skills (OFS) and early supportive intervention and/or feeding therapy if needed using the newly developed scoring system, the Mansoura Early Feeding Skills Assessment “MEFSA” for the other four months. Infants in both groups were studied from the day of admission till discharge.ResultsIn addition to age and weight criteria, other indicators for oral feeding readiness and oral motor skills were respected, such as oral feeding readiness cues, feeding practice, feeding maintenance, and feeding techniques. By following this approach, preterm infants achieved earlier start oral feeding (SOF) and full oral feeding (FOF) and were discharged with shorter periods of tube feeding. Infants gained weight without increasing their workload to the NICU team.ConclusionThe newly applied approach proved to be a successful bedside scoring system scale for assessing preterm infants’ early oral feeding independence skills in the NICU. It offers an early individualized experience of oral feeding without clinical complications.

The effect of oral motor intervention with different initiation times to improve feeding outcomes in preterm infants: protocol for a single-blind, randomized controlled trial

BackgroundPremature infants commonly encounter difficulties with oral feeding, a complication that extends hospital stays, affects infants’ quality of life, and imposes substantial burdens on families and society. Enhancing preterm infants’ oral feeding skills and facilitating their transition from parenteral or nasal feeding to full oral feeding pose challenges for neonatal intensive care unit (NICU) healthcare professionals. Research indicates that oral motor interventions (OMIs) can enhance preterm infants’ oral feeding capabilities and expedite the transition from feeding initiation to full oral feeding. Nonetheless, the most suitable timing for commencing these interventions remains uncertain.MethodsThis is a single-blind, randomized controlled trial. Preterm with a gestational age between 29+0 to 34+6 weeks will be eligible for the study. These infants will be randomized and allocated to one of two groups, both of which will receive the OMIs. The intervention commences once the infant begins milk intake during the early OMIs. Additionally, in the late OMIs group, the intervention will initiate 48 h after discontinuing nasal continuous positive airway pressure.DiscussionOMIs encompass non-nutritive sucking and artificial oral stimulation techniques. These techniques target the lips, jaw, muscles, or tongue of premature infants, aiming to facilitate the shift from tube feeding to oral feeding. The primary objective is to determine the ideal intervention timing that fosters the development of oral feeding skills and ensures a seamless transition from parenteral or nasal feeding to full oral feeding among preterm infants. Furthermore, this study might yield insights into the long-term effects of OMIs on the growth and neurodevelopmental outcomes of preterm infants. Such insights could bear substantial significance for the quality of survival among preterm infants and the societal burden imposed by preterm birth.Trial registrationchictr.org.cn ChiCTR2300076721.

Acceptance of bite presentations and feeding behaviors of 8 to 12-month-old infants: A reflection of typical feeding development

PurposeThe lack of age-appropriate expectations for feeding acceptance patterns in early childhood is a barrier to early and accurate identification of pediatric feeding disorder (PFD). The objective of the study was to describe the process by which typically developing children 8–12 months of age accept or refuse bite presentations and their corresponding feeding behaviors, aiming to establish age-appropriate normative data for feeding acceptance. MethodUsing cross-sectional methodology, we studied the proportion of bite presentations accepted, the type of feeding behaviors-passive, disruptive, expulsion, feeding concerns- observed at presentation and acceptance or refusal, and the duration between presentation to acceptance or refusal in 63 healthy infants between 8 and 12 months of age. Descriptive statistics and a one-way ANOVA were conducted to compare the effect of age and texture. ResultsFindings reveal high levels of bite acceptance of 80 % or > for children across ages, but with lower texture-specific differences. Both passive and disruptive behaviors were present even during acceptance of bites without any expulsion. Feeding concerns showed developmental trends with rapid reduction by 12 months suggesting improvement in oral feeding skills. The duration of acceptance and refusals revealed clear patterns by age and texture with an average of 3 s for acceptance but <1 s for refusal. ConclusionsThis study describes bite acceptance patterns in a cohort of typically developing infants between 8 and 12 months of age by examining the acceptance of bites, frequency and type of feeding behaviors, and duration differences when children accept versus refuse a bite. Findings may be applied in the future to provide more sensitive detection of problematic feeding patterns to aid in the detection of pediatric feeding disorder.

Lung ultrasound supports clinical evaluation of feeding competence development in preterm neonates.

The achievement of alimentary competencies is a milestone in the development of preterm neonates. Ten percent of neonates <37 weeks of gestational age and 25% of those VLBW experience swallowing disorders, with an increased risk of problems in the early phase of life (failure to thrive, growth retardation, inhalation, and consequent risk of pulmonary infection) and later in life due to delayed development of oromotor skills.The main diagnostic tools for swallowing disorders are endoscopic (fiber-optic endoscopic examination of swallowing, FEES) or radiographic (videofluoroscopic swallowing study, VFSS) exams. Given the invasiveness of these methods and the bias due to rheologic differences between bolus and contrast medium, FEES and VFSS are poorly reproducible. Moreover, neither of the technique is capable of detecting post-meal inhalations, especially microinhalations or those consequent to a whole meal rather than to a single swallowing.Lung ultrasound (LUS) is a widespread, repeatable, safe, fast point-of-care tool and we reported previous encouraging results in detecting silent and overt inhalation related to the meal in children with dysphagia/gastroesophageal reflux disease (GERD) risk factors. We report a pilot study, that investigated LUS approach (performing imaging before and after meals) to assess feeding competence development in a cohort of n. 19 newborns <32 weeks of age. Meal monitoring by LUS did not show any significant difference in scoring before/after eating. The achievement of full enteral feeding correlates with GA at birth (p < 0.001) but not with LUS scoring. The introduction of the first meal by bottle correlates both with gestational age (p < 0.001) and ultrasound scores (p = 0.004). LUS score at 7 days of life resulted predictive for length of invasive/non-invasive respiratory support (p = 0.002) and length of oxygen supply (p = 0.001), while LUS score at 48 h of life did not (p n.s.). Our study suggests that the development of oral feeding skills is not strictly dependent on gestational age. Moreover, our research suggests the predominant role of LUS in predicting the time of readiness to oral feeding, as the LUS score can be a marker of respiratory and lung wellness, and consequently a predictor of neonate stability during deglutitory apnea.

Effects of oral stimulation on feeding readiness of preterm infants: A randomized controlled study

BackgroundFeeding readiness is an indicator to assess whether preterm infants can tolerate oral feeding. The Preterm Infant Oral Motor Intervention (PIOMI) may improve infant oral motor function and feeding skills. MethodsTo determine the PIOMI effect on feeding readiness, 46 preterm infants were randomly assigned to either the oral stimulation or standard care group. The Preterm Oral Feeding Readiness Assessment Scale (POFRAS) was used to repeatedly assess participants’ feeding readiness on Day 1 (baseline), Day 3, and Day 7. FindingsThe two groups had similar demographic characteristics. While the baseline POFRAS scores showed non-significant differences between the two groups, the oral stimulation group performed better on Days 3 and 7. DiscussionThe group-by-time interaction assessment indicated a marginally significant difference in the time trend of the POFRAS scores between the two groups. Application to practiceThese results can be helpful for achieving full oral feeding in the NICU.

The Evaluation of Oral Feeding in Preterm Infants: Turkish Validation of the Early Feeding Skills Assessment Tool

Objective:The Early Feeding Skills Assessment Tool (EFS) is a valid and reliable tool for evaluating preterm infants’ oral feeding skills and readiness during the transition to oral feeding. There is currently no instrument with tested validity and reliability available to evaluate the oral feeding skills and readiness of preterm infants in Turkey. The aim of this study was to fill the need for such an instrument for use in the Turkish population by adapting and validating the EFS for the assessment of Turkish preterm infants during the transition to oral feeding.Material and Methods:This methodological, cross-sectional study included 107 preterm infants. Validity of the EFS-Turkish was tested with linguistic, content, and construct validity analyses, and its reliability was tested using internal consistency and item analyses.Results:A panel of experts confirmed the content validity of the items in the EFS-Turkish (content validity index = 0.97). Cronbach’s alpha for the total instrument was 0.95, supporting its internal consistency reliability. Item–total correlations ranged from 0.58 to 0.83 (P < .001). Confirmatory factor analysis confirmed the established EFS structure of 19 items and 5 factors. The tool demonstrated good model fit statistics (χ2/df = 2.24; P < .001).Conclusion:The EFS-Turkish is a valid and reliable instrument for use in neonatal intensive care units to evaluate the feeding skills of preterm infants during the transition to oral feeding. The use of the EFS-Turkish is recommended to facilitate the safe and successful development of preterm infants’ oral feeding skills and to plan evidence-based initiatives.

Infant Bottle-Feeding: A Prospective Study of Infant Physiology and Parental Report Metrics

ABSTRACT The aim of this study was to examine associations between parent reports of bottle-feeding behaviors and infant non-nutritive suck (NNS) on a pacifier as well as oral feeding skills during bottle-feeding. A prospective study was conducted. Full-term infants with no prior diagnosed feeding disorders were recruited at 3-months. Parents reported their infant’s bottle-feeding behaviors using the Neonatal Eating Assessment Tool-Bottle-Feeding (NeoEAT-Bottle-Feeding), consisting of five domains: Infant Regulation, Energy and Physiologic Stability, Gastrointestinal Tract Function, Sensory Responsiveness, and Compelling Symptoms of Problematic Feeding. Infant NNS was measured using a custom pacifier, pressure transducer device, which yields the following NNS variables: duration (sec), frequency (Hz), amplitude (cmH20), cycles per burst, cycle amount, and burst amount. The Oral Feeding Skills (OFS) scale was used to measure the initial volume, transfer volume, proficiency, and rate of milk transfer during bottle feeding. Fifty-two infants (58% male) with reported prior bottle experience completed this study. NeoEAT-Bottle-Feeding Total score was significantly positively associated with NNS burst duration and NNS cycles per burst. The NeoEAT-Bottle-Feeding Energy and Physiologic Stability domain was significantly positively correlated with NNS cycles per burst. NeoEAT-Bottle-Feeding Gastrointestinal Tract Function domain score was significantly positively correlated with NNS duration, amplitude, and cycles per burst. There were no significant associations between NeoEAT-Bottle-Feeding domains and the OFS scale. The findings demonstrate that parent reports of problematic feeding at 3 months of age are associated with aspects of infant NNS physiology and not with oral feeding metrics during bottle-feeding. Parent reports of bottle-feeding behaviors, particularly pertaining to gastrointestinal issues, were associated with aspects of infant NNS. These data together will allow for a more nuanced understanding of infant feeding and will be beneficial in determining if infants have a feeding delay.

Developing the Mansoura Early Feeding Skills Assessment Scale for Preterm Infants.

This study aimed to develop a new bedside scoring system scale that assesses preterm infants' oral feeding skills (OFS) in the neonatal intensive care unit (NICU). A literature review and critical appraisal of available oral feeding assessment tools/scores were performed. Subsequently, we developed the "Mansoura Early Feeding Skills Assessment" (MEFSA) scale, an 85-item observational measure of oral feeding skills with three main sections. Forty-one preterm infants who did not receive oral feeding but were clinically stable enough to initiate oral feeding were included in the study. Next, we applied and interpreted the MEFSA to describe and score their feeding skills. Applying the MEFSA resulted in a smooth feeding transition, early start of oral feeding, full oral feeding, and discharge with a shorter period of tube feeding in preterm infants. The MEFSA is a successful bedside scoring system that assesses the OFS of preterm infants in the NICU.

Evaluation of the Effect of Oral Motor Stimulation Exercises on Feeding Skills in Premature Infants.

Oral feeding in preterm infants is a complex and dynamic process involving oral motor development and interaction between the neurological, cardiorespiratory, and gastrointestinal systems. Oral motor stimulation (OMS) is defined as stimulating the oropharyngeal components such as the lips, jaw, tongue, and soft palate with fingers in preterm infants to increase their feeding skills. In this study, we aimed to evaluate the effect of OMS exercises on the sucking and swallowing skills of preterm infants and demonstrate the utility of objective scales to evaluate infants' readiness for oral feeding. This single-center, prospective cohort study was conducted between June 1st and December 31st, 2020, which included preterm infants born at ≤34 weeks of gestation and admitted to the neonatal intensive care unit of our hospital. All procedures of the OMS program were performed once a day, 5 times a week by a language and speech therapist who is an expert in oral feeding skills (OFS) staging and non-nutritive sucking (NNS) scoring. All infants were followed up until discharge with a weekly evaluation of OFS staging and NNS scoring. A total of 50 infants were included in this prospective cohort study. The mean birth weight was 1376.9±372 g, and the median gestational age was 30 weeks (interquartile range: 25-34). The comparison of OFS stages on day 5 and day 10 of OMS revealed a significant increase (p<0.001). Similarly, there was a significant improvement in the NNS scores on days 5 and 10 compared to the baseline. In preterm infants, OMS during the transition from gavage feeding to oral feeding improves feeding skills.

Assessment and management of feeding difficulties for infants with complex CHD.

Early surgical intervention in infants with complex CHD results in significant disruptions to their respiratory, gastrointestinal, and nervous systems, which are all instrumental to the development of safe and efficient oral feeding skills. Standardised assessments or treatment protocols are not currently available for this unique population, requiring the clinician to rely on knowledge based on neonatal literature. Clinicians need to be skilled at evaluating and analysing these systems to develop an appropriate treatment plan to improve oral feeding skill and safety, while considering post-operative recovery in the infant with complex CHD. Supporting the family to re-establish their parental role during the hospitalisation and upon discharge is critical to reducing parental stress and oral feeding success.

The home environment and its relation to bottle feeding outcomes in the first year of life

BackgroundThe home environment and caregiver interactions have an impact on infant development. However, there is a paucity of research surrounding the home environment and its relation to early feeding outcomes within the first year of life. Therefore, the aim of this study was to examine the relationship between the home environment and infant bottle feeding outcomes at 3 and 12 months of age. MethodsSeventy-two full-term infants completed this study at 3 months of age and fifty-five infants completed the study at 12 months. Data in the current study were collected from a larger, ongoing study completed in the infant's home at 3 and 12 months of age. The Infant-Toddler Home Observation for Measurement of Environment Inventory (IT-HOME) was utilized to assess the infant's home environment. The Oral Feeding Skills (OFS) scale was completed while the infant was observed during a bottle feed. Caregivers completed a questionnaire about their infant's feeding abilities via the Neonatal Eating Assessment Tool (Neo-EAT) at 3 months and Pediatric Eating Assessment Tool (Pedi-EAT) at 12 months. ResultsAt 3 months of age, the IT-HOME Involvement subscale was associated with an increase in the amount of milk provided in the infant's bottle. There were no significant associations between the IT-HOME and caregiver report of feeding at 3 months of age. At 12 months of age, the IT-HOME Acceptance subscale was associated with an increase in oral transfer rate and the IT-HOME Variety subscale was associated with a decrease in oral transfer rate. Additionally, the IT-HOME Organization subscale was associated with caregiver report of feeding on the following Pedi-EAT scales: Mealtime Behaviors, Selective Restrictive Eating, and Oral Processing at 12 months. ConclusionsThese findings reveal that the home environment is significantly related to different infant bottle feeding outcomes over the first year of life. At 3 months, IT-HOME Involvement was associated with the amount of milk offered in the bottle, whereas at 12 months of age, subscales of the IT-HOME were associated with oral feeding transfer rate and caregiver report of feeding. Clinically, these findings point to the importance of considering the infant's bottle feeding skills in conjunction with certain aspect within the infant's environment. Additional research is needed to further explore these relationships in greater detail, with a larger sample size and across patient populations.

Effect of oral motor facilitation technique on oral motor and feeding skills in children with cerebral palsy : a case study

Background:Deficiencies in oral motor function and feeding skills are common in children with cerebral palsy (CP). Oral motor therapy is a useful method to improve oral motor function and feeding skills. Oral motor facilitation technique (OMFT) is a newly designed comprehensive oral motor therapy, including postural control, sensory adaptation, breathing control, sensorimotor facilitation, and direct feeding.Methods:This study was performed to identify the effect of OMFT on oral motor function and feeding skills in children with CP. A total of 21 children with CP (3–10 years, GMFCS III–V) participated in 16 weeks (16 sessions) of OMFT. The effects on oral motor function and feeding skills were assessed using the Oral Motor Assessment Scale (OMAS) before the treatment, 8 and 16 weeks after OMFT. Data were analyzed using the Friedman test and post-hoc analysis.Results:Significant improvement was found in oral motor function and feeding skills including mouth closure, lip closure on the utensil, lip closure during deglutition, control of the food during swallowing, mastication, straw suction, and control of liquid during deglutition after OMFT. Mouth closure was the most effective and mastication was the least effective item. Sixteen weeks is more effective than 8 weeks of OMFT.Conclusion:OMFT could be an effective and useful oral motor therapy protocol to improve oral motor function and feeding skills in children with CP.

Effects of Swaddling During Bottle Feeding in Preterm Infants.

Preterm infants have immature oral feeding skills, affecting length of hospital stay and long-term feeding outcomes. Swaddling has positive effects on pain and stress responses, state regulation, and physiological stability in preterm infants in the neonatal intensive care unit (NICU). Swaddling during bottle feeding may support preterm infant behavioral organization and oral feeding skills. Swaddling is used inconsistently during feeding in the NICU and has not been critically examined for effects on bottle feeding performance in preterm infants. To examine the effects of swaddling on bottle feeding quality and efficiency in preterm infants. A convenience sample of 30 infants born before 34 weeks of gestation was selected in an urban level IV NICU. Using an experimental, randomized crossover design, each infant was swaddled for one feeding and unswaddled for one feeding. Feeding efficiency was measured by rate and volume consumed. Feeding quality was examined by the Early Feeding Skills Assessment and frequency of physiological changes. Data were analyzed using dependent t tests and Wilcoxon signed rank test. When swaddled, participants demonstrated significantly better scores on all related subtests of the Early Feeding Skills Assessment ( P ≤ .001). Infants demonstrated no difference in frequency of bradycardia or oxygen desaturations greater than 4 seconds. No significant differences were found in feeding efficiency outcomes. Swaddling can be used in the NICU to improve bottle feeding quality in preterm infants. Future investigation is needed on long-term effects of swaddling during bottle feeding on feeding performance, weight gain, and length of stay.

A Unique Clinical Tool for the Evaluation of Oral Feeding Skills in Infants.

Background. Occupational therapy practice for oral feeding assessment is based on clinical observation of infants' sucking, swallowing, and breathing ability, which is influenced by clinical experience and provides poor evidence on explanatory factors. Purpose. To test the clinical utility and safety of a nipple monitoring device for the quantitative evaluation of oral feeding skills. Method. Sixteen infants, with no severe medical complications, participated in a pre-experimental pilot study. Oral feeding performances (duration, intake volume, and rate of transfer), and occurrence of adverse events (apnea, bradycardia, and oxygen desaturations) were recorded to ensure the tool does not interfere with infant's feeding ability or does not create any adverse effects. Findings. There was no significant difference in duration, intake volume, rate of transfer between the two monitored sessions, and no occurrence in adverse events. Implications. The findings suggest that the nipple monitoring device may be used for quantitative assessment and intervention planning of oral feeding difficulties in infants.
