Risk of death at home or on hospital readmission after discharge with pediatric tracheostomy.

OBJECTIVE: To evaluate outcomes of patients discharged home following tracheostomy, including the timing and place of death for non-survivors. STUDY DESIGN: We retrospectively reviewed medical records of infants undergoing tracheostomy between 2006 and 2017, within the first year of life for congenital or acquired neonatal conditions. RESULTS: Of the 224 patients discharged after tracheostomy, 127 (57%) required home mechanical ventilation (MV). Overall, 40 (18%) patients died (65% were on MV); 38% of the deaths occurred at home and 63% at a subsequent hospitalization. Having tube feeding was identified as significantly associated with increased mortality on multivariate analysis. Having a tracheostomy for upper airway obstruction was the only variable significantly associated with increased risk of death at home on multivariate analysis. CONCLUSIONS: Having tube feeding was associated with increased risk of death overall and having the tracheostomy for obstructive airway conditions was associated with death occurring at home.

Previous missed visits and independent risk of loss to follow-up in the high-risk neonatal follow-up clinic.

BACKGROUND: Neonatal intensive care unit (NICU) patients are at high risk for developmental delays. As a result, many are seen in neonatal follow-up (NFU) clinics. Disparities in NFU follow-up rates by social determinants of health exist. AIMS: Determine how the number of missed visits (composed of patient-canceled visits and no-show visits) relates to risk of loss to follow-up in the NFU clinic. STUDY DESIGN: Retrospective cohort study at a regional specialty center in the United States. SUBJECTS: 262 patients born between January 1, 2014, and December 31, 2017, who were referred to the NFU clinic. OUTCOME MEASURES: Logistic binomial regression was used to model risk ratio of loss to follow-up over two years, defined as not attending a recommended follow-up visit and not informing the clinic of a reason for discontinued care. RESULTS: Of 262 infants, 220 patients (84 %) were seen for at least one visit and 143 (65 %) completed follow-up. Younger maternal age, maternal smoking during pregnancy, maternal drug use during pregnancy, and public insurance were all associated with missing more visits. For each additional missed visit, the risk of loss to follow-up was 1.73 times higher unadjusted (95 % CI: 1.33, 2.26) and 1.81 times higher (95 % CI: 1.36, 2.40) after adjusting for confounders. The risk ratio of loss to follow-up for no-show visits was three times higher than that for patient-canceled visits. CONCLUSIONS: Each missed visit was independently associated with higher risk of loss to follow-up from NFU clinic, even after adjusting for other risk factors.

Back Transfer of Infants with Tracheostomies: A Regional Center Experience.

We describe our center's experience with the back transfer of infants following tracheostomies. We conducted a retrospective cohort study of infants transferred to pediatric critical care units of our regional center with conditions originating in the neonatal period who underwent tracheostomy during the hospitalization within their first year of life between 2006 and 2017. Recovering patients are discharged home or transferred back to the referring hospitals. We evaluated patient characteristics, destination of discharge and type of pulmonary support at discharge, and mechanical ventilation (MV) or tracheotomy masks (TM). Of the 139 included patients, 72% were transferred to the neonatal intensive care unit, 21% to the pediatric cardiothoracic unit, and 7% to the pediatric intensive care unit. Their median gestational age was 35 weeks. They were admitted at a median 22 days of life and lived at a median distance of 56 miles from our center. Furthermore, 34 infants (24%) were back transferred closer to their homes (23 with MV and 11 with TM), and 84 (60%) were discharged home (53 on MV and 31 on TM). Twenty-one patients (15%) died in the hospital (before discharge or transfer). Back transferred patients on MV had a significantly shorter duration between tracheostomy and transfer compared with those discharged home from our center: MV (median = 22 vs. 103 days, p < 0.0001) and TM (median = 13 vs. 35 days, p < 0.0001). Back transfer of infants with tracheostomies closer to their homes was associated with a significantly shorter hospitalization and more efficient use of the subspecialized resources at the RC.

Pulmonary Support of Infants with Tracheotomies in a Regional Neonatal Intensive Care Unit.

OBJECTIVE: We evaluate patient characteristics, hospital course, and outcome by type discharge pulmonary support; mechanical ventilation (MV) or with tracheotomy masks (TM). STUDY DESIGN: We reviewed records of infants admitted to the neonatal intensive care unit (NICU) that underwent tracheotomy within their first year of life between 2006 and 2017. We evaluated patient characteristics, referral pattern, destination of discharge, and outcome by type of pulmonary support at discharge (MV vs. TM). RESULTS: Of the 168 patients, 63 (38%) were inborn, 91 (54%) transferred to our NICU, and 5 (3%) were readmitted after being home. Median gestational age at birth was 34 weeks. Twenty-three (14%) infants were transferred to hospitals closer to their homes (13 with MV and 10 with TM), and 125 (74%) were discharged home (75 on MV and 50 on TM). Twenty patients (12%) died in the regional center (RC). Among those discharged home from our RC, infants on MV were of lower birth weight and younger gestational age, had tracheostomies later in life, had longer duration between tracheostomy to discharge to home, and had longer total duration of hospitalization at the RC. In addition, infants in the MV group were more frequently dependent on MV at time of placement of tracheostomies, less frequently had congenital airway anomalies and more frequently having possibly acquired airway anomalies and more frequently having major congenital anomalies, more frequently treated with diuretics, inhaled medications and medications for pulmonary hypertension, and more frequently had gastrostomies for feeding compared with the TM group. CONCLUSION: Patients with tracheostomies in the NICU and discharged from RC on MV or TM vary by patient characteristic, timing of tracheostomy placement, timing of discharge from RC, type of upper airway anomalies, duration of stay in the hospital, and complexity of medical condition at discharge. KEY POINTS: · Infants on home mechanical ventilation have long hospital stay and complex conditions at discharge.. · We describe factors associated with the type of pulmonary support for infants with tracheostomies.. · Treatment strategy may influence type of discharge pulmonary support in infants with tracheostomies..

Fetal intervention for congenital chylothorax is associated with improved outcomes in early life.

BACKGROUND: Congenital chylothorax (CC) can have devastating consequences for neonates. We sought to determine the outcomes of cases treated at our institution and evaluate the role of fetal intervention. MATERIALS AND METHODS: With Institutional Review Board approval, patients treated at our institution 09/2006-04/2016 with CC were reviewed. History and outcomes were compared between patients undergoing fetal intervention (fetal group) and patients who did not (control group). RESULTS: Twenty-three patients were identified. Mean gestational age at birth was 35 wk. Overall mortality was 30% (7 patients). Nineteen patients (83%) were prenatally diagnosed, and 10 patients (43%) underwent fetal intervention. Birth weight was significantly lower in the fetal group compared to the control group (median interquartile range [IQR]; 2.5 [2.3-3.0] versus 3.3 [2.6-3.7] kg, P = 0.02). Apgar scores were significantly higher in the fetal group than the control group at 1 and 5 min (median [IQR]; 6 [4-8] versus 1 [1-2], P = 0.005 and 8 [7-9] versus 2 [2-6], P = 0.008, respectively). For those patients with prenatal diagnosis of CC and hydrops fetalis, thrombosis and lymphopenia were both improved in the fetal group (thrombosis 0% versus 40%, P = 0.03; lymphocyte nadir [median {IQR}] 1.5 [0.6-2.9] versus 0.1 [0.05-0.2], P = 0.02). Duration of support with mechanical ventilation was significantly shorter in the fetal group (median [IQR]; 1 [0-40] versus 41 [29-75] d, P = 0.04). CONCLUSIONS: Fetal intervention for CC is associated with improved Apgar scores and decreased ventilator days and complications in patients with hydrops fetalis. Fetuses with chylothorax, especially those with hydrops, should be referred to a fetal center for evaluation.

Evidence-based management of chylothorax in infants.

PURPOSE: Management guidelines for infants with chylothorax lack substantial evidence. We sought to identify variables that impact outcomes in these patients in order to develop an evidence-based management algorithm. METHODS: We retrospectively reviewed the medical records of all infants diagnosed with chylothorax from June 2005 to December 2014 at our institution. Data collected included demographics, chest tube output (CTO), medical and dietary interventions, surgical procedures, and absolute lymphocyte count (ALC). Outcomes analyzed included death, sepsis, necrotizing enterocolitis (NEC), requiring surgery, and success of therapy, defined as CTO decrease by >50% within 7days. RESULTS: Of 178 neonates with chylothorax, initial therapy was high medium chain triglyceride (MCT) feedings in 106 patients, nothing by mouth (NPO), total parenteral nutrition (TPN) in 21, and NPO/TPN plus octreotide in 45. Octreotide use in addition to NPO/TPN revealed no significant differences in any outcome including success (47% vs. 43%, p=0.77). Initial CTO and ALC correlated with needing surgery (p=0.002 and p=0.006, respectively), and with death (p=0.028 and p=0.043, respectively). ALC also correlated with sepsis (p<0.001). CONCLUSIONS: Octreotide has no advantage over NPO/TPN alone in infants with chylothorax. CTO and ALC predict requiring surgery. We propose a management guideline based on CTO and ALC without a role for octreotide. TYPE OF STUDY: Retrospective case-control study. LEVEL OF EVIDENCE: 3.

Congenital chylothorax.

Congenital chylothorax (CC) results from multiple lymphatic vessel anomalies or thoracic cavity defects and may accompany other congenital anomalies. Fetal chylothorax may increase the risk of death and complications from pleural space lymphatic fluid accumulation, which compromises lung development, pulmonary, and cardiovascular function and from complications arising from the loss of drained lymphatic contents. Prenatal interventions might improve survival in severe cases of fetal chylothorax. The neonatal treatment strategy is generally supportive with interventions that include thoracostomy drainage and attempts to decrease chyle flow using a stepwise approach that begins with the least invasive means. Evidence-based treatment choices are lacking and are much needed. Most cases of CC resolve with time even without specific lymphatic system studies to identify the exact pathology. Expertise in performing lymphatic studies is not universally available. Data on both efficacy and safety of the various therapeutic options are needed to determine the best approach to the treatment of CC.

Lung dose analysis in loco-regional hypofractionated radiotherapy of breast cancer.

OBJECTIVES: To report the ipsilateral lung dosimetry data of breast cancer (BC) patients treated with loco-regional hypofractionated radiotherapy (HFRT).  METHODS: Treatment plans of 150 patients treated in the Radiotherapy Unit, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia between January 2012 and March 2015 by HFRT for BC were retrospectively reviewed. All patients received 42.4 Gy in 16 fractions by tangential and supra-clavicular fields with 6 MV, 18 MV, or mixed energies. Ipsilateral lung dosimetric data V20Gy and mean lung dose (MLD) were recorded. Correlations between lung dose, patient characteristics, and treatment delivery parameters were assessed by a logistic regression test. RESULTS: The mean ipsilateral lung V20Gy was 24.6% and mean MLD was 11.9 Gy. A weak, but statistically significant correlation was found between lung dose and lung volume (p=0.043). The lung dose was significantly decreasing with patient separation and depth of axillary lymph node (ALN) and supra-claviculary lymph nodes (SCLN) (p less than 0.0001), and increasing with ALN (p=0.001) and SCLN (p=0.003) dose coverage. Lung dose significantly decreased with beam energy (p less than 0.0001): mean V20Gy was 27.8%, 25.4% for 6 MV, mixed energy, and 21.2% for 18 MV. The use of a low breast-board angle correlates with low lung dose. CONCLUSION: Our data suggest that the use of high energy photon beams and low breast-board angulation can reduce the lung dose.

Uterine perforation and its dosimetric implications in cervical cancer high-dose-rate brachytherapy.

PURPOSE: To retrospectively assess the incidence of sub-serosal and uterine perforation of intra-uterine tandem in intracavitary high-dose-rate (HDR) brachytherapy for cervical cancer, and to evaluate its dosimetric implications on computed tomography (CT)-based treatment planning. MATERIAL AND METHODS: Computed tomography images and brachytherapy plans of cervical cancer patients treated from February 2006 to December 2012 were reviewed for sub-optimal implants (sub-serosal and uterine perforation), and their correlation with cancer FIGO stage and patients' age. For each patient, the plans showing sub-optimal insertion of intra-uterine tandem were analyzed and compared to plans with adequate insertion. The difference in dose coverage of clinical-target-volume (CTV) and variation of the dose delivered to organs-at-risk (OARs) rectum and bladder were evaluated. RESULTS: A total of 231 brachytherapy plans for 82 patients were reviewed. We identified 12 (14.6%) patients and 14 (6%) applications with uterine perforation, and 12 (14.6%) patients and 20 (8.6%) applications with sub-serosal insertion of tandem. Data analysis showed that advanced stage correlates with higher incidence of sub-optimal implants (p = 0.005) but not the age (p = 0.18). Dose-volume-histograms (DVHs) analysis showed large variations for CTV dose coverage: D90 significantly decreased with average of -115.7% ± 134.9% for uterine perforation and -65.2% ± 82.8% for sub-serosal insertion (p = 0.025). The rectum and bladder dose assessed by D2cc increased up to 70.3% and 43.8%, respectively, when sub-optimal insertion of uterine tandem occurred. CONCLUSIONS: We report a low incidence of uterine perforation and sub-serosal insertion of uterine tandem in intracavitary HDR brachytherapy for cervical cancer. However, the effects on treatment plan dosimetry can be considerably detrimental. Therefore, we recommend image-guided insertion, at least for the challenging cases.

Evaluation of Heart Rate Assessment Timing, Communication, Accuracy, and Clinical Decision-Making during High Fidelity Simulation of Neonatal Resuscitation.

Objective. Accurate heart rate (HR) determination during neonatal resuscitation (NR) informs subsequent NR actions. This study's objective was to evaluate HR determination timeliness, communication, and accuracy during high fidelity NR simulations that house officers completed during neonatal intensive care unit (NICU) rotations. Methods. In 2010, house officers in NICU rotations completed high fidelity NR simulation. We reviewed 80 house officers' videotaped performance on their initial high fidelity simulation session, prior to training and performance debriefing. We calculated the proportion of cases congruent with NR guidelines, using chi square analysis to evaluate performance across HR ranges relevant to NR decision-making: <60, 60-99, and ≥100 beats per minute (bpm). Results. 87% used umbilical cord palpation, 57% initiated HR assessment within 30 seconds, 70% were accurate, and 74% were communicated appropriately. HR determination accuracy varied significantly across HR ranges, with 87%, 57%, and 68% for HR <60, 60-99, and ≥100 bpm, respectively (P < 0.001). Conclusions. Timeliness, communication, and accuracy of house officers' HR determination are suboptimal, particularly for HR 60-100 bpm, which might lead to inappropriate decision-making and NR care. Training implications include emphasizing more accurate HR determination methods, better communication, and improved HR interpretation during NR.

The effect of late preterm birth on mortality of infants with hypoplastic left heart syndrome.

OBJECTIVES: We evaluated the effect of late preterm (34 to 36 weeks' gestation) delivery on hospital mortality of infants with hypoplastic left heart syndrome (HLHS). STUDY DESIGN: Retrospective review of records of infants born at or after 34 weeks with no other lethal anomalies, cared for in a single tertiary perinatal center between 2002 and 2009. Factors associated with death prior to discharge from the hospital were ascertained using univariate and multivariate analyses. RESULTS: Of the 243 infants with HLHS, 35 were late preterm and 208 were ≥37 weeks (term). Using logistic regression analysis, late preterm delivery (odds ratio [OR] 2.95; 95% confidence interval [CI] 1.35 to 6.45), the presence of other major cardiac defects (OR 3.76; 95% CI 1.31 to 10.81), and the presence of noncardiac congenital anomalies (OR 6.13; 95% CI 1.43 to 26.22) were independently associated with hospital death. CONCLUSION: Late preterm birth of infants with HLHS was independently associated with an increased risk of hospital death compared with those delivered at term.

Back transport of neonates: effect on hospital length of stay.

INTRODUCTION: In a regionalized perinatal system, recovering neonates may be back transported from a regional Neonatal Intensive Care Unit (NICU) to community hospitals closer to their residence to convalesce prior to hospital discharge. OBJECTIVE: This study evaluates the practice of neonatal back transport for growth and the duration of total hospitalization. METHODS: We conducted a retrospective study comparing length of stay (LOS) for infants back transported from a regional NICU to a level II nursery for convalescent care (BT), with LOS for infants eligible for back transport discharged home from the Regional Center (RC). RESULTS: A total of 221 infants were studied. BT infants (n=104) had lower birth weights (median; 1955 vs 2700 g, p=0.001), more frequently needed mechanical ventilation (84 vs 65%, p=0.002) and parenteral nutrition (71 vs 55%, p=0.013), less frequently were evaluated by subspecialists (20 vs 59% p=0.0001), and had longer total LOS (median; 20 vs 11 days, p<0.0001) compared to infants discharged home from the RC (n=117). However, in the subgroup with birth weights

Barriers to screening infants for retinopathy of prematurity after discharge or transfer from a neonatal intensive care unit.

OBJECTIVE: To assess neonatal intensive care unit (NICU) practices affecting screening and follow-up for retinopathy of prematurity (ROP). METHODS: Retrospective study of infants at risk for ROP, eligible for back transport, admitted to a regional NICU from January 1, 1999 until May 31, 2002. Patients failed to receive needed follow-up for ROP after discharge or transfer from a NICU, if we could not verify their ROP screening follow-up within 1 month. RESULTS: A total of 74 infants were identified to need follow-up eye care. Infants who did not receive the follow-up care had greater mean gestational age (mean SD; 30.7+/-2.3 vs 29.6+/-2.5 weeks, p=0.05) and birth weights (mean SD; 1581+/-366 vs 1360+/-508 g, p=0.007), compared to infants who received the recommended care. Infants transported back to the community hospital were significantly more likely to miss follow-up eye care compared to infants discharged from the regional center (relative risk 2.81, 95% confidence interval (CI) (1.09 to 7.20)). Infants not screened for ROP in the NICU had greater risk for missing follow-up care compared to infants who had their first retinal examination in the NICU (relative risk 4.25, 95% CI (1.42 to 12.73)). CONCLUSIONS: Infants transferred back or discharged from the NICU before ROP screening represent a high-risk group for not receiving follow-up eye care.

Immediate changes in lung compliance following natural surfactant administration in premature infants with respiratory distress syndrome: a controlled trial.

OBJECTIVE: To compare immediate changes in lung compliance following the administration of two commercially available natural surfactants. METHOD: We conducted a prospective, randomized study of 40 preterm infants with respiratory distress syndrome requiring surfactant. Infants received either Infasurf or Survanta. The primary outcome measure was the change in compliance assessed by bedside pulmonary monitoring. RESULTS: There were no significant changes in dynamic lung compliance within or between the two groups 1 hour after surfactant administration. However, infants given Survanta required more doses per patient (4 vs 2, p=0.05) and were more likely to require >2 doses (57 vs 26%, p=0.05). Infants requiring >1 dose of surfactant had a greater change in airway pressure and improved oxygenation just before the second dose when treated with Infasurf. CONCLUSIONS: We found no significant difference in acute changes in lung compliance. However, treatment with Infasurf seems to be more long lasting than Survanta.
