RESUMEN

OBJECTIVE: To determine whether implementation of an education-based intervention can sustainably improve upstream and downstream outcomes in intubated patients in a pediatric intensive care unit (PICU) in a low-resource country. DESIGN: Quality improvement study comparing airway-related morbidity in two previously studied patient cohorts pre-intervention (Epoch 1) and immediately post-intervention (Epoch 2) with a third cohort thirty-six months post-intervention (Epoch 3). SETTING: PICU of the largest public children's hospital in El Salvador. PATIENTS: 147 patients under 18 years requiring intubation and mechanical ventilation (MV) met inclusion criteria in the long-term follow-up period and were consecutively sampled without exclusion (Epoch 3) (compared to 98 previously studied patients in the short-term follow-up period (Epoch 2)). INTERVENTION: A low-cost, education-based intervention to close knowledge gaps, improve communication among PICU doctors, nurses, and respiratory therapists, and optimize patient outcomes. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was change in unplanned extubation (UE) between Epochs 2 and 3. Other outcomes included use of cuffed endotracheal tubes (ETT), rate of elective ETT change and days of MV. The 17 % decrease in UE previously reported for Epoch 2 was sustained in Epoch 3. There was a statistically significant increase in use of cuffed ETT from 35.7 % in Epoch 2-55.1 % in Epoch 3 (p = 0.003, z-score -2.99). There was also a statistically significant mean difference in rate of elective ETT change per 100 MV days from Epoch 2 to Epoch 3 of 1.7 (p = 0.007; 95 % CI 0.15-0.84). There was no change in MV days from Epoch 2 to Epoch 3 (p-value 0.764; 95 % CI -1.48-2.02). Beyond these quantifiable results, many unanticipated practice changes were observed three years after the initial intervention. CONCLUSIONS: Sustained improvement in upstream and downstream outcomes (UE, cuffed ETT use, elective ETT change) for intubated patients in a low-resource PICU were observed three years after a low-cost, low-touch, education-based intervention.

RESUMEN

Background: This work describes a sustainable and replicable initiative to optimize multi-disciplinary care and uptake of clinical best practices for patients in a pediatric intensive care unit in Low/Middle Income Countries and to understand the various factors that may play a role in the reduction in child mortality seen after implementation of the Quality Improvement Initiative. Methods: This was a longitudinal assessment of a quality improvement program with the primary outcome of intubated pediatric patient mortality. The program was assessed 36 months following implementation of the quality improvement intervention using a t-test with linear regression to control for co-variates. An Impact Pathway model was developed to describe potential pathways for improvement, and context was added with an exploratory analysis of adoption of the intervention and locally initiated interventions. Results: 147 patients were included in the sustainability cohort. Comparing the initial post-implementation cohort to the sustainability cohort, the overall PICU unexpected extubations per 100 days mechanical ventilation decreased significantly from baseline (6.98) to the first year post intervention (3.52; p < 0.008) but plateaued without further significant decrease in the final cohort (3.0; p = 0.73), whereas the mortality decreased from 22.4 (std 0.42) to 9.5% (std 0.29): p value: 0.002 (confidence intervals: 0.05;0.21). The regression model that examined age, sex, diagnosis and severity of illness (via aggregate Pediatric Risk of Mortality (PRISM) scores between epochs) yielded an adjusted R-squared (adjusting for the number of predictors) value of 0.046, indicating that approximately 4.6% of the variance in mortality was explained by the predictors included in the model. The overall significance of the regression model was supported by an F-statistic of 3.198 (p = 0.00828). age, weight, diagnosis, and severity of illness. 15 new and locally driven quality practices were observed in the PICU compared to the initial post-implementation time period. The Impact Pathway model suggested multiple unique potential pathways connecting the improved patient outcomes with the intervention components. Conclusion: Sustained improvements were seen in the care of intubated pediatric patients. While some of this improvement may be attributable to the intervention, it appears likely that the change is multifactorial, as evidenced by a significant number of new quality improvement projects initiated by the local clinical team. Although currently limited by available data, the use of Driver Diagram and Impact Pathway models demonstrates several proposed causal pathways and holds potential for further elucidating the complex dynamics underlying such improvements.

RESUMEN

OBJECTIVE: To identify the prevalence of hearing impairment and associated risk factors in children living with human immunodeficiency virus (HIV) in Haiti. METHODS: A validated smartphone-based platform with pure-tone audiometry was used to screen 341 HIV-infected children for hearing impairment in Port-au-Prince, Haiti from March 2019 to September 2020. If screening was failed, a more comprehensive pure-tone audiometric evaluation was administered. Demographic, otologic, and HIV-related data were obtained through caregiver surveys and medical charts. Statistical analysis included univariate and multivariate logistic regression. RESULTS: Sixty (18%) of 341 HIV-infected children (ages 7-18 years) had hearing impairment. Of those failing their hearing assessment, 17 (28%) had moderate and 5 (8%) had severe or profound hearing loss. Hearing impairment was associated with frequent ear infections (OR 3.37; 95% CI 1.76-6.46; p < 0.001) and family history of hearing loss (OR 5.12; 95% CI 2.14-12.23; p = 0.001) but not viral load (OR 1.00; 95% CI 0.73-1.02; p = 0.28) or antiretroviral therapy duration (OR 0.96; 95% CI 0.79-1.17; p = 0.66). Only 35% of caregivers correctly perceived their child's hearing loss. CONCLUSIONS: Hearing impairment occurs at a higher prevalence in HIV-infected children in Haiti than what is expected for those living without HIV. Frequent ear infections were significantly associated with hearing loss while antiretroviral therapy duration was not. Despite their potential ototoxicity, antiretroviral therapies should be continued and may decrease incidence of otitis media. Low caregiver perception of hearing loss emphasizes the need for routine hearing screening for HIV-infected children.

RESUMEN

Children are more likely to experience recurrent laryngeal nerve (RLN) injury during thyroid surgery. Intraoperative nerve monitoring (IONM) may assist in nerve identification and surgical decision making. A literature review of pediatric IONM was performed and used to inform a monitoring technique guide and expert opinion statements. Pediatric IONM is achieved using a variety of methods. When age-appropriate endotracheal tubes with integrated surface electrodes are not available, an alternative method should be used. Patient age and surgeon experience with laryngoscopy influence technique selection; four techniques are described in detail. Surgeons must be familiar with the nuances of monitoring technique and interpretation; opinion statements address optimizing this technology in children. Adult IONM guidelines may offer strategies for surgical decision making in children. In some cases, delay of second-sided surgery may reduce bilateral RLN injury risk.

RESUMEN

INTRODUCTION: Unplanned extubation (UE) is orders of magnitude worse in low-income Pediatric Intensive Care Units (PICUs) than their high-income counterparts. Furthermore, a significant percent (20 %) of UEs result in a destabilizing event or cardiac collapse that negatively contributes to morbidity and mortality. As the principles of safe airway management are universal, we hypothesize that a multi-disciplinary educational intervention bundle which included provision of low-cost cuffed endotracheal tubes (ETT) and ETT tape will decrease the rate of unplanned extubation (UE) in a low-resourced PICU. METHODS: This is a pre-post interventional study powered to evaluate UE of intubated pediatric patients in an El Salvadorian PICU after a multi-disciplinary educational effort and provision of low-cost disposable materials. A multidisciplinary (otolaryngologists, intensivists, anesthesiologists, respiratory therapists, and nurses) educational curriculum involving hands on training, online video modules readily available via bedside QR codes, and pre- and post-testing was administered. The cost of the intervention materials was $1.32 per child. PICU mortality was evaluated as an exploratory outcome. RESULTS: Nine-hundred and fifty-seven (859 pre-intervention and 98 post-intervention) patients met inclusion criteria. Patients with one or more UEs decreased significantly from 29.4 % to 17.3 % post-intervention (p = 0.01; CI: 0.28-0.88) with an odds ratio of 0.51. The use of a cuffed ETT increased from 12 % to 36 % (p < 0.001; CI: 0.17-0.44; OR:3.74) and cuffed ETT use was associated with a reduction in UE with an odds ratio of 0.40 (p < 0.001; CI: 0.24-0.66). Finally, there was a 4.3 % decrease in pediatric mortality from 26.7 % to 22.4 % that equates to a number needed to treat to prevent a single child mortality of 23. Therefore, the ICER per mortality prevented is $30.7 and the ICER per Disability Adjusted Life Year (DALY) is $0.44. CONCLUSION: This multi-faceted intervention bundle is an accessible, scalable, cost-effective means to reduce UE and has implications in reducing global pediatric mortality.

RESUMEN

Systemic disease is an uncommon cause of subglottic stenosis (SGS). We report a case of severe SGS due to underlying eosinophilic granulomatosis with polyangiitis (EGPA) in a child presenting with isolated stridor. EGPA is a rare systemic vasculitis with very limited cases reported in the pediatric population. While surgical intervention was required given the degree of stenosis in this case, medical management of the underlying systemic disease process is critical when there is clinical suspicion of SGS in the context of systemic vasculitis.

RESUMEN

The goal of this prospective cohort study was to characterize the ability of teachers to identify schoolchildren at risk of hearing loss in order to maximize hearing screening efficiency in low-resource settings. At 4 semirural schools in Malindi, Kenya, preselected schoolchildren perceived as hearing impaired were compared to children thought to have normal hearing using portable audiometry. Eight of 127 children (54% male) failed hearing screening, all of who were identified by schoolteachers as having a high risk of hearing loss. Thus, for every 5 children prescreened by schoolteachers, an average of 1 child would be identified as having hearing loss. Overall, teacher prescreening had a 100% hearing loss identification rate and a 20% referral rate. In conclusion, in resource-limited settings, where universal hearing screening is challenging, teachers can effectively identify children with hearing loss for early intervention.

RESUMEN

OBJECTIVE/HYPOTHESIS: To assess the long-term decannulation outcomes of bioresorbable microplates as an external stent for pediatric tracheostomy patients with suprastomal collapse. STUDY DESIGN: Retrospective cohort study. METHODS: Hospital records of all patients who underwent a bioresorbable microplate for suprastomal collapse from 2016 to 2019 were reviewed at a single institution. The primary outcome measure was tracheostomy decannulation. RESULTS: A total of nine patients underwent placement of bioabsorbable microplates to treat suprastomal collapse. After initial tracheostomy, four patients received a laryngotracheal reconstruction prior to their external stent placement, and one patient received a mandibular distraction. The average age at the time of external stent placement was 32 (±21) months, excluding one patient who received a stent at the age of 29 years. Eight patients (88.9%) were successfully decannulated following the procedure. Decannulated patients were followed for an average of 21 (±12.5) months postoperatively, and all these patients have remained decannulated since their initial procedure. This is a total of 173 months (14.4 years) of observation postprocedure in which these patients have remained decannulated. One patient experienced postoperative crepitus requiring washout but still maintained decannulation. CONCLUSION: Bioabsorbable microplates have a reasonable chance of long-term successful decannulation when an appropriate patient is selected. Decannulation is maintained beyond the 6-month time frame in which the 85:15 poly(L-lactide-co-glycolide) polymer that comprises the external stent takes to bioabsorb. This procedure should be considered for the often difficult problem of pediatric tracheostomy with isolated suprastomal collapse. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E631-E634, 2021.

RESUMEN

OBJECTIVES/HYPOTHESIS: Patients with Down syndrome have a high incidence of obstructive sleep apnea (OSA) and limited treatment options. Hypoglossal stimulation has shown efficacy but has not yet been approved for pediatric populations. Our objective is to characterize the therapy response of adolescent patients with down syndrome and severe OSA who underwent hypoglossal stimulation. STUDY DESIGN: Prospective longitudinal trial. METHODS: We are conducting a multicenter single-arm trial of hypoglossal stimulation for adolescent patients with Down syndrome and severe OSA. Interim analysis was performed to compare objective sleep and quality of life outcomes at 12 months postoperatively for the first 20 patients. RESULTS: The mean age was 15.5 and baseline AHI 24.2. Of the 20 patients, two patients (10.0%) had an AHI under 1.5 at 12 months; nine patients of 20 (45.0%) under five; and 15 patients of 20 (75.0%) under 10. The mean decrease in AHI was 15.1 (P < .001). Patients with postoperative AHI over five had an average baseline OSA-18 survey score of 3.5 with an average improvement of 1.7 (P = .002); in addition, six of these patients had a relative decrease of apneas compared to hypopneas and seven had an improvement in percentage of time with oxygen saturation below 90%. CONCLUSIONS: Patients with persistently elevated AHI 12 months after hypoglossal implantation experienced improvement in polysomnographic and quality of life outcomes. These results suggest the need for a closer look at physiologic markers for success beyond reporting AHI as the gold standard. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:1663-1669, 2021.

RESUMEN

OBJECTIVE: To address whether a multidisciplinary team of pediatric otolaryngologists, anesthesiologists, pediatric intensivists, speech-language pathologists, and nurses can achieve safe and sustainable surgical outcomes in low-resourced settings when conducting a pediatric airway surgical teaching mission that features a program of progressive autonomy. STUDY DESIGN: Consecutive case series with chart review. SETTING: This study reviews 14 consecutive missions from 2010 to 2019 in Ecuador, El Salvador, and the Dominican Republic. METHODS: Demographic data, diagnostic and operative details, and operative outcomes were collected. A country's program met graduation criteria if its multidisciplinary team developed the ability to autonomously manage the preoperative huddle, operating room discussion and setup, operative procedure, and postoperative multidisciplinary pediatric intensive care unit and floor care decision making. This was assessed by direct observation and assessment of surgical outcomes. RESULTS: A total of 135 procedures were performed on 90 patients in Ecuador (n = 24), the Dominican Republic (n = 51), and El Salvador (n = 39). Five patients required transport to the United States to receive quaternary-level care. Thirty-six laryngotracheal reconstructions were completed: 6 single-stage, 12 one-and-a-half-stage, and 18 double-stage cases. We achieved a decannulation rate of 82%. Two programs (Ecuador and the Dominican Republic) met graduation criteria and have become self-sufficient. No mortalities were recorded. CONCLUSION: This is the largest longitudinal description of an airway reconstruction teaching mission in low- and middle-income countries. Airway reconstruction can be safe and effective in low-resourced settings with a thoughtful multidisciplinary team led by local champions.

RESUMEN

Congenital nasal piriform aperture stenosis and choanal atresia are types of nasal obstructions that can be life threatening to infants if left untreated. While there has been numerous reports on both of them there has not been a single reported case of congenital nasal piriform aperture atresia. Here, we present the first case of piriform aperture atresia that includes the diagnostic and clinical approach.

RESUMEN

SARS-CoV-2, the novel coronavirus resulting in the present COVID-19 pandemic, has increased the otolaryngologist's reliance on telemedicine to manage outpatient pathology. The nature of telemedicine, however, limits a provider's ability to obtain a comprehensive physical examination, specifically of the tympanic membrane. Various smartphone-based otoscopic attachments are now available that facilitate patient-obtained otoscopic image capture of the tympanic membrane. Here, we present 3 cases in which a patient-purchased, over-the-counter otoscope was utilized to alter otologic management during the time of social distancing. Further research is necessary to improve our understanding the safety and efficacy of patient-based "at-home" otoscopic examination and to optimize the use of these devices.

RESUMEN

Significant misinformation about COVID-19 has been spread on the internet. Parents of children with complex aerodigestive problems have a hard time understanding the information they encounter on the internet and the news media and interpreting how it relates to their child's complex needs. Our multidisciplinary team, at the suggestion of a parent, hosted 3 virtual "town halls" in which families could ask questions directly of pediatric otolaryngology, pediatric pulmonology and case management in order to efficiently obtain factual evidence-based up-to-date advice. The information discussed at the town halls was then annotated and disseminated via active, parent-run aerodigestive social media forums. The information disseminated via the town halls reached 4787 Facebook participants.

RESUMEN

OBJECTIVE: The prevalence of chronic rhinosinusitis (CRS), defined by mucosal thickening on imaging, approaches 100% in the cystic fibrosis (CF) population. CRS is associated with significant morbidity in CF, including its ability to trigger pulmonary exacerbations. CRS in CF is typically managed by pediatricians, otolaryngologists and pulmonologists. This survey evaluates the variance in practice patterns of CRS in CF amongst specialists. METHODS: This is a cross-sectional, electronic survey in which maximum variation purposive sampling was used by a multi-disciplinary group of pediatric, otolaryngology and pulmonology providers in order to select a survey population with expertise in CRS in CF patients. The survey was distributed to 381 practitioners from September to October 2019. RESULTS: 175 participants responded (45% response rate). Ten (of 54) statements achieved 75% consensus agreement. Consensus statements included: The decision to pursue surgical intervention for CRS in CF is a multi-disciplinary approach (94%; n = 146); maximal medical management should include nasal saline irrigation (93%; n = 142), topical steroids (75%; n = 117), maximal medical management should not include intravenous steroids (79%; n = 122); image guidance in surgery is necessary for all surgery involving the frontal sinuses (77%; n = 43), and all revision surgery(80%, n = 45); the appropriate setting for sinus surgery in a CF patient varies depending on patient presentation (89%; n = 133); post-operative regimen should include nasal saline (93%; n = 137); but does depend on the severity of disease discovered intra-operatively (84%; n = 124); post-operative antibiotics should be guided by intra-operative culture data (82%; n = 121). CONCLUSIONS: There is a great deal of variation amongst specialists in the treatment of CRS in CF, however 10 statements met consensus criteria and should be considered when forming clinical care guidelines in this population.
