Hence, this study aims to predict neonatal resuscitation and affecting factors by applying machine learning. Methods: The design employed for this study was a retrospective cohort study. Data for all deliveries is gathered from the electronic health record system at a tertiary Hospital, in Bandar Abbas, Iran, between January 2020 and December 2022. Women with a single cephalic pregnancy were included, while fetal malformations were used as exclusion criteria. Twenty-eight potential factors were initially selected as a feature selection. The input data were used to train eight machine learning models. In our evaluation, we utilized accuracy, the area under the curve (AUC) of the receiver operating characteristic, precision, and recall to assess the performance. Results: During the study period, 230 (7.5%) newborns required resuscitation. The likelihood of requiring resuscitation was higher for preterm newborns, babies born to multiparous women, and those delivered via cesarean section. Conversely, mothers who received support from a doula during labor had reduced odds of neonatal resuscitation. Conditions such as preeclampsia, hypothyroidism, fetal distress, intrauterine growth retardation, and lower fetal weight were found to be linked with an increased likelihood of neonatal resuscitation. Additionally, it was observed that male newborns required more frequent resuscitation. The area under the curve (AUC) for each model turned out to be: Deep learning feed-forward (0.90), random forest classification (0.87), XGBoost classification (0.85), decision tree classification (0.85), permutation classification - knn (0.80), linear regression (0.79), light gradient-boosting (0.75), and logistic regression (0.72). All eight models showed a high accuracy ranging between 0.72-0.87. However, random forest classification performed best with AUC: 087, accuracy: 0.87, precision: 0.84, and recall: 0.90. Conclusions Employing a clinical database and multiple machine learning algorithms to assess the requirement for neonatal resuscitation shows potential benefits. Further prospective research involving intrapartum clinical attributes is necessary to enhance prediction accuracy neonatal resuscitation artificial intelligence machine learning neonatal outcome Figures Figure 1 Figure 2 Background The majority of newborns adjust to life outside the womb without any assistance. Approximately 10% may require some help, while less than 1% might need cardiac compression or medication in the delivery room [ 1 ]. Every year, approximately 1 million newborns globally lose their lives due to birth asphyxia [ 2 ]. The World Health Organization's basic newborn resuscitation guideline states that despite birth asphyxia accounting for about one-fourth of neonatal deaths, timely cardiopulmonary resuscitation during childbirth can prevent around 30% of these fatalities [ 3 ]. The data from various countries also indicates that the likelihood of mortality rises by 16% for every 30-second postponement in starting ventilation for up to six minutes and increases by 6% for every minute of delay in providing bag and mask ventilation [ 4 ]. Hence, it is evident that the initial moments following birth play a crucial role in lowering neonatal mortality rates. Research indicates that adequate resuscitation of newborns by competent, well-trained healthcare professionals, is essential in delivering suitable and sufficient intervention with the capacity to avert nearly two million neonatal deaths annually due to intrapartum-related asphyxia [ 5 ]. Usually, there is enough advance notice for a team of providers to prepare for a potential resuscitation when a newborn is born. Before birth, known risk factors can help assess the probability of requiring resuscitation [ 6 ]. Therefore, a decision-support system that accurately predicts the necessity for resuscitation would be valuable to patients and healthcare providers. This system could inform obstetricians in advance about the need for resuscitation in newborns, allowing them to carry out the required procedures immediately after birth. This would enhance the effectiveness of care provided and lower medical errors. According to our information, only one study used machine learning techniques to predict resuscitation and its risk factors in the neonatal population [ 7 ]. Hence, this study aims to predict neonatal resuscitation and affecting factors by applying machine learning. Methods The design employed for this study was a retrospective cohort study. The study's primary outcome was resuscitation, defined as a set of interventions during birth to help the newborn start breathing and establish circulation. After reviewing the literature [ 8 , 9 ], twenty eight potential factors linked to the necessity for neonatal resuscitation were initially recognized. These factors included age, place of residency, maternal education, medical insurance, nationality, history of infertility, history of neonatal death, the onset of labor, gestational age, parity, attendance of prenatal education courses, having a doula during the process in labor, method of childbirth, maternal anemia, cardiovascular disease, substances use, prolonged rupture of membrane, diabetes, maternal body mass index, preeclampsia, hypothyroidism, placenta abruption, meconium amniotic fluid, fetal distress, intrauterine growth retardation, chronic hypertension, newborn weight, and newborn sex. The abovementioned data was collected from the electronic health record system at Khaleej-e-Fars Hospital, a medical center providing specialized care in Bandar Abbas, Iran. Electronic health data for all deliveries is gathered and managed by midwives as a regular part of clinical care. The Research Committee Board of Hormozgan University of Medical Sciences approved the study. We received electronic health records for all deliveries between January 2020 and December 2022. Women with a single cephalic pregnancy were included, while fetal malformations were used as exclusion criteria. The initial step of the analysis entailed comparing no resuscitation needed with resuscitated newborns based on the listed variables. Variables with a noteworthy p-value (below 0.5) were selected as features for the machine learning method. The provided data was utilized to develop eight machine learning models. All machine learning models underwent L2 normalization for feature normalization except for tree-based models. The output of each machine-learning model fell within the range of 0 to 1. Given that neonatal resuscitation is infrequent, it was anticipated that the non-resuscitated newborns would have a significantly larger size compared to the resuscitated newborns. To prevent bias in model development and performance evaluation caused by excessively imbalanced datasets, random undersampling was conducted with a 1:10 ratio of the critical group to the non-critical group. The entire dataset was used for model development and testing, employing a five-fold cross-validation technique. This method ensured that the training and test datasets were separated appropriately, reducing any potential result distortion caused by specific divisions. Specifically, the data was split into five parts, with four used for learning and one for testing, and this five-fold testing process was conducted without any overlap. In our assessment, we employed accuracy, reflecting the ratio of correct predictions to the total predictions made. Furthermore, we evaluated the area under the curve (AUC) of the receiver operating characteristic, precision (the count of accurate predictions for a class divided by the overall predictions for that class), and recall (the count of accurate predictions for a class divided by the total actual occurrences of that class) to measure the effectiveness. For all the statistical analyses, we utilized SPSS (version 25.0, IBM Corp, Armonk, NY, United States) and Python software (version 3.7.0). Results During the study period, 2832 out of 3062 deliveries at our center (92.5%) did not require resuscitation for the newborns, while 230 newborns (7.5%) needed resuscitation. In Table 1 , you can find the maternal demographic characteristics linked to the necessity for neonatal resuscitation. None of the maternal demographic factors were found to be related to the need for neonatal resuscitation.

Discussion Machine learning (ML) falls under the category of artificial intelligence and is experiencing quick growth within the technical domain. Due to the immense volume of structured and unstructured data (big data), ML has become essential, as traditional methods are impractical for handling such data [ 10 ]. Big data allows machine learning algorithms to discover previously unknown patterns, which in turn influences the decision-making process. Machine learning involves teaching machines to mimic human behavior. Machine learning is widely used in many different fields in today’s society. Its main applications involve classification and prediction [ 11 – 13 ]. So far, fewer machine-learning models have been released in the neonatology field. In this study, we carried out a cohort study to assess how effective machine learning models are in predicting the need for neonatal resuscitation. We applied eight different machine learning models to identify the predictors of the neonatal need for resuscitation. All eight models showed a high accuracy ranging between 0.72–0.87. However, random forest classification performed best with AUC: 087, accuracy: 0.87, precision: 0.84, and recall: 0.90. Based on our findings, 7.5% of newborns required resuscitation. The likelihood of requiring resuscitation was higher for preterm newborns, babies born to multiparous women, and those delivered via cesarean section. Conversely, mothers who received support from a doula during labor had reduced odds of neonatal resuscitation. Conditions such as preeclampsia, hypothyroidism, fetal distress, intrauterine growth retardation, and lower fetal weight were found to be linked with an increased likelihood of neonatal resuscitation. Not much prior research has delved into the predictions for neonatal resuscitation needs. Aziz et al. discovered that maternal hypertension, maternal infection, multiple pregnancies, and oligohydramnios are distinct factors that independently increase the risk of requiring positive pressure ventilation and/or endotracheal intubation [ 6 ]. In a research conducted by Afjeh et al., it was found that low birth weight, meconium-stained amniotic fluid, and chorioamnionitis are separate risk factors for needing endotracheal intubation [ 14 ]. De Almeida and colleagues discovered that multiple pregnancies, maternal hypertension, mal-presentation, cesarean section, and lower gestational age were all predictors of neonatal need for resuscitation [ 15 ]. Recently a study by Lee et al., indicated that extensive resuscitation at birth was linked to lower gestational age, lower birth weight, birth weight below the third percentile, being male, maternal hypertension, abnormal levels of amniotic fluid, lack of antenatal steroid use, being born outside the hospital, and chorioamnionitis [ 16 ]. Among all predictors defined by previous studies using both traditional statistical analysis and machine learning models, gestational age was considered the primary indicator in determining the likelihood of infant mortality and the necessity for resuscitation. Our research aligns with the majority of studies in this area, showing that both pre-term and late-term babies required resuscitation more frequently than full-term babies [ 17 , 18 ]. Lung immaturity in preterm newborns and the potential for co-complications in late-term pregnancy, such as the presence of meconium in the amniotic fluid, raises the likelihood of need for resuscitation [ 19 , 20 ]. One previous study using data mining to predict the need for neonatal resuscitation showed sensitivity results higher than 90% and specificity and accuracy results superior to 98%, which were considered satisfactory [ 7 ]. Our findings also showed a high accuracy. Our model has the potential to significantly change neonatal care by providing clinicians with accurate predictions and enabling timely interventions, which has a significant clinical impact. The application ML in multiple fields of medicine is certainly demonstrating significant potential to enhance healthcare. ML algorithms find applications in various tasks, including diagnosis and treatment, as well as drug discovery and personalized healthcare. ML's capability to examine large datasets and detect intricate patterns is resulting in improved diagnoses, enhanced treatments, and streamlined healthcare systems [ 21 – 27 ]. Our study's use of eight different machine-learning models is a key strength. However, our study has several limitations. One limitation is the retrospective design. To reduce selection bias, we made efforts to include all consecutive mothers who gave birth during the study period. Essential variables that would allow assessment of the fetus, such as biophysical profile, amniotic fluid index, and corticosteroid use before childbirth in cases of preterm births, were not included in the machine learning database. Male sex and newborn weight were associated with extensive resuscitation at birth but were not used in the predictive model because those factors cannot be determined before labor. These limitations should be considered in further studies. Conclusion The probability of needing resuscitation was greater for preterm infants, infants born to multiparous mothers, and those born through cesarean delivery. In contrast, mothers assisted by a doula during labor experienced lower chances of needing neonatal resuscitation. Conditions like preeclampsia, hypothyroidism, fetal distress, intrauterine growth restriction, and reduced fetal weight were associated with a higher chance of neonatal resuscitation. Moreover, it was noted that male infants needed resuscitation more often. Employing a clinical database and multiple machine learning algorithms to assess the requirement for neonatal resuscitation shows potential benefits. If confirmed in other cohorts, a prediction system that effectively forecasts the need for resuscitation could offer significant benefits to both patients and healthcare professionals. Further prospective research involving intrapartum clinical attributes is necessary to enhance prediction accuracy.

resuscitation","fulltext":[{"header":"Background","content":"\u003cp\u003eThe majority of newborns adjust to life outside the womb without any assistance. Approximately 10% may require some help, while less than 1% might need cardiac compression or medication in the delivery room [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. Every year, approximately 1\u0026nbsp;million newborns globally lose their lives due to birth asphyxia [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. The World Health Organization's basic newborn resuscitation guideline states that despite birth asphyxia accounting for about one-fourth of neonatal deaths, timely cardiopulmonary resuscitation during childbirth can prevent around 30% of these fatalities [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. The data from various countries also indicates that the likelihood of mortality rises by 16% for every 30-second postponement in starting ventilation for up to six minutes and increases by 6% for every minute of delay in providing bag and mask ventilation [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. Hence, it is evident that the initial moments following birth play a crucial role in lowering neonatal mortality rates. Research indicates that adequate resuscitation of newborns by competent, well-trained healthcare professionals, is essential in delivering suitable and sufficient intervention with the capacity to avert nearly two million neonatal deaths annually due to intrapartum-related asphyxia [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eUsually, there is enough advance notice for a team of providers to prepare for a potential resuscitation when a newborn is born. Before birth, known risk factors can help assess the probability of requiring resuscitation [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Therefore, a decision-support system that accurately predicts the necessity for resuscitation would be valuable to patients and healthcare providers. This system could inform obstetricians in advance about the need for resuscitation in newborns, allowing them to carry out the required procedures immediately after birth. This would enhance the effectiveness of care provided and lower medical errors. According to our information, only one study used machine learning techniques to predict resuscitation and its risk factors in the neonatal population [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. Hence, this study aims to predict neonatal resuscitation and affecting factors by applying machine learning.\u003c/p\u003e"},{"header":"Methods","content":"\u003cp\u003eThe design employed for this study was a retrospective cohort study. The study's primary outcome was resuscitation, defined as a set of interventions during birth to help the newborn start breathing and establish circulation. After reviewing the literature [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e], twenty eight potential factors linked to the necessity for neonatal resuscitation were initially recognized. These factors included age, place of residency, maternal education, medical insurance, nationality, history of infertility, history of neonatal death, the onset of labor, gestational age, parity, attendance of prenatal education courses, having a doula during the process in labor, method of childbirth, maternal anemia, cardiovascular disease, substances use, prolonged rupture of membrane, diabetes, maternal body mass index, preeclampsia, hypothyroidism, placenta abruption, meconium amniotic fluid, fetal distress, intrauterine growth retardation, chronic hypertension, newborn weight, and newborn sex. The abovementioned data was collected from the electronic health record system at Khaleej-e-Fars Hospital, a medical center providing specialized care in Bandar Abbas, Iran. Electronic health data for all deliveries is gathered and managed by midwives as a regular part of clinical care. The Research Committee Board of Hormozgan University of Medical Sciences approved the study. We received electronic health records for all deliveries between January 2020 and December 2022. Women with a single cephalic pregnancy were included, while fetal malformations were used as exclusion criteria.\u003c/p\u003e \u003cp\u003eThe initial step of the analysis entailed comparing no resuscitation needed with resuscitated newborns based on the listed variables. Variables with a noteworthy p-value (below 0.5) were selected as features for the machine learning method. The provided data was utilized to develop eight machine learning models. All machine learning models underwent L2 normalization for feature normalization except for tree-based models. The output of each machine-learning model fell within the range of 0 to 1.\u003c/p\u003e \u003cp\u003eGiven that neonatal resuscitation is infrequent, it was anticipated that the non-resuscitated newborns would have a significantly larger size compared to the resuscitated newborns. To prevent bias in model development and performance evaluation caused by excessively imbalanced datasets, random undersampling was conducted with a 1:10 ratio of the critical group to the non-critical group. The entire dataset was used for model development and testing, employing a five-fold cross-validation technique. This method ensured that the training and test datasets were separated appropriately, reducing any potential result distortion caused by specific divisions. Specifically, the data was split into five parts, with four used for learning and one for testing, and this five-fold testing process was conducted without any overlap.\u003c/p\u003e \u003cp\u003eIn our assessment, we employed accuracy, reflecting the ratio of correct predictions to the total predictions made. Furthermore, we evaluated the area under the curve (AUC) of the receiver operating characteristic, precision (the count of accurate predictions for a class divided by the overall predictions for that class), and recall (the count of accurate predictions for a class divided by the total actual occurrences of that class) to measure the effectiveness. For all the statistical analyses, we utilized SPSS (version 25.0, IBM Corp, Armonk, NY, United States) and Python software (version 3.7.0).\u003c/p\u003e"},{"header":"Results","content":"\u003cp\u003eDuring the study period, 2832 out of 3062 deliveries at our center (92.5%) did not require resuscitation for the newborns, while 230 newborns (7.5%) needed resuscitation.

The neonatal need for resuscitation was linked to gestational age, parity, the presence of a doula, and the method of childbirth. The likelihood of requiring resuscitation was higher for preterm newborns, babies born to multiparous women, and those delivered via cesarean section. Conversely, mothers who received support from a doula during labor had reduced odds of neonatal resuscitation.\u003c/p\u003e\n\u003cp\u003e\u003c/p\u003e\u0026nbsp;\u003ctable id=\"Tab2\"

Big data allows machine learning algorithms to discover previously unknown patterns, which in turn influences the decision-making process. Machine learning involves teaching machines to mimic human behavior. Machine learning is widely used in many different fields in today\u0026rsquo;s society. Its main applications involve classification and prediction [\u003cspan additionalcitationids=\"CR12\" citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. So far, fewer machine-learning models have been released in the neonatology field. In this study, we carried out a cohort study to assess how effective machine learning models are in predicting the need for neonatal resuscitation. We applied eight different machine learning models to identify the predictors of the neonatal need for resuscitation. All eight models showed a high accuracy ranging between 0.72\u0026ndash;0.87. However, random forest classification performed best with AUC: 087, accuracy: 0.87, precision: 0.84, and recall: 0.90.\u003c/p\u003e \u003cp\u003eBased on our findings, 7.5% of newborns required resuscitation. The likelihood of requiring resuscitation was higher for preterm newborns, babies born to multiparous women, and those delivered via cesarean section. Conversely, mothers who received support from a doula during labor had reduced odds of neonatal resuscitation. Conditions such as preeclampsia, hypothyroidism, fetal distress, intrauterine growth retardation, and lower fetal weight were found to be linked with an increased likelihood of neonatal resuscitation. Not much prior research has delved into the predictions for neonatal resuscitation needs. Aziz et al. discovered that maternal hypertension, maternal infection, multiple pregnancies, and oligohydramnios are distinct factors that independently increase the risk of requiring positive pressure ventilation and/or endotracheal intubation [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. In a research conducted by Afjeh et al., it was found that low birth weight, meconium-stained amniotic fluid, and chorioamnionitis are separate risk factors for needing endotracheal intubation [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. De Almeida and colleagues discovered that multiple pregnancies, maternal hypertension, mal-presentation, cesarean section, and lower gestational age were all predictors of neonatal need for resuscitation [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Recently a study by Lee et al., indicated that extensive resuscitation at birth was linked to lower gestational age, lower birth weight, birth weight below the third percentile, being male, maternal hypertension, abnormal levels of amniotic fluid, lack of antenatal steroid use, being born outside the hospital, and chorioamnionitis [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eAmong all predictors defined by previous studies using both traditional statistical analysis and machine learning models, gestational age was considered the primary indicator in determining the likelihood of infant mortality and the necessity for resuscitation. Our research aligns with the majority of studies in this area, showing that both pre-term and late-term babies required resuscitation more frequently than full-term babies [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e, \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]. Lung immaturity in preterm newborns and the potential for co-complications in late-term pregnancy, such as the presence of meconium in the amniotic fluid, raises the likelihood of need for resuscitation [\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e, \u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e].

However, our study has several limitations. One limitation is the retrospective design. To reduce selection bias, we made efforts to include all consecutive mothers who gave birth during the study period. Essential variables that would allow assessment of the fetus, such as biophysical profile, amniotic fluid index, and corticosteroid use before childbirth in cases of preterm births, were not included in the machine learning database. Male sex and newborn weight were associated with extensive resuscitation at birth but were not used in the predictive model because those factors cannot be determined before labor. These limitations should be considered in further studies.\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003eThe probability of needing resuscitation was greater for preterm infants, infants born to multiparous mothers, and those born through cesarean delivery. In contrast, mothers assisted by a doula during labor experienced lower chances of needing neonatal resuscitation. Conditions like preeclampsia, hypothyroidism, fetal distress, intrauterine growth restriction, and reduced fetal weight were associated with a higher chance of neonatal resuscitation. Moreover, it was noted that male infants needed resuscitation more often. Employing a clinical database and multiple machine learning algorithms to assess the requirement for neonatal resuscitation shows potential benefits. If confirmed in other cohorts, a prediction system that effectively forecasts the need for resuscitation could offer significant benefits to both patients and healthcare professionals.

Hence, this study aims to predict neonatal resuscitation and affecting factors by applying machine learning.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods: \u003c/strong\u003eThe design employed for this study was a retrospective cohort study. Data for all deliveries is gathered from the electronic health record system at a tertiary Hospital, in Bandar Abbas, Iran, between January 2020 and December 2022. Women with a single cephalic pregnancy were included, while fetal malformations were used as exclusion criteria. Twenty-eight potential factors were initially selected as a feature selection. The input data were used to train eight machine learning models. In our evaluation, we utilized accuracy, the area under the curve (AUC) of the receiver operating characteristic, precision, and recall to assess the performance.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults:\u003c/strong\u003e During the study period, 230 (7.5%) newborns required resuscitation. The likelihood of requiring resuscitation was higher for preterm newborns, babies born to multiparous women, and those delivered via cesarean section. Conversely, mothers who received support from a doula during labor had reduced odds of neonatal resuscitation. Conditions such as preeclampsia, hypothyroidism, fetal distress, intrauterine growth retardation, and lower fetal weight were found to be linked with an increased likelihood of neonatal resuscitation. Additionally, it was observed that male newborns required more frequent resuscitation. The area under the curve (AUC) for each model turned out to be: Deep learning feed-forward (0.90), random forest classification (0.87), XGBoost classification (0.85), decision tree classification (0.85), permutation classification - knn (0.80), \u0026nbsp;linear regression (0.79), light gradient-boosting (0.75), and logistic regression (0.72). All eight models showed a high accuracy ranging between 0.72-0.87. However, random forest classification performed best with AUC: 087, accuracy: 0.87, precision: 0.84, and recall: 0.90.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusions\u003c/strong\u003e Employing a clinical database and multiple machine learning algorithms to assess the requirement for neonatal resuscitation shows potential benefits.
