- Abstract
Background: Intraoperative bronchospasm in pediatric patients supported through laryngeal mask airways (LMAs) is commonly treated with pressurized metered-dose inhaler (pMDI) albuterol. The aim of the study was to evaluate delivery of pMDI albuterol through LMAs under different conditions in a model of infant/child supported with a ventilator., Methods: We compared drug delivery efficiency of 4 actuations of albuterol pMDI (captured on a filter placed between the LMA and a test lung), drug deposition in the circuit (elbow) and in the LMA under different experimental conditions. Outcomes were expressed of percentage of nominal dose. We compared devices (valved holding chamber [VHC] and adapter), timing of administration (inspiration and expiration), tidal volumes (50 mL and 100 mL), mode of actuation (single and multiple), and LMA sizes (1, 1.5, and 2). Multiple regression analysis was used to evaluate the contribution of each to these components to the outcomes. P < .05 was considered statistically significant., Results: Results are expressed as median (interquartile range) of pooled data. Drug delivery efficiency was 0% (0-1.1) and 6.3% (3.2-14.7) for adapter and VHC, respectively. Elbow deposition was 25.8% (19.2-63.3) and 2.9% (1.4-6.4) for adapter and VHC, respectively. LMA deposition was 2.6% (1.3-4.6) and 4.6% (2.9-6.1) for adapter and VHC, respectively. Multiple regression analysis showed that device, timing of actuation, and LMA size explained 33%, 17%, and 8% of the observed variation in delivery efficiency (R
2 0.63), respectively. Multiple regression analysis showed that device and timing of actuation explained 52% and 16% of the observed variation, respectively (R2 0.70). Multiple regression analysis poorly explained factors associated with LMA deposition (R2 0.22)., Conclusions: Using a VHC, actuating the pMDI during exhalation, and using a small LMA size increased drug delivery efficiency. The adapter was an inefficient add-on device for aerosol delivery with a pMDI through an LMA that caused significant circuit deposition., (Copyright © 2024 by Daedalus Enterprises.)- Published

- Abstract
Tracheostomized children have higher mortality compared to adults due to smaller airway anatomy and greater medical complexity and are at high risk for life-threatening complications. Following new tracheostomy placement, caregivers are required to successfully complete extensive training before discharge home. Training for tracheostomy emergencies such as tube obstruction and accidental decannulation is challenging without real-life, hands-on experience, but simulation training has shown promising effects on improving caregiver knowledge and comfort in preparing for emergency situations. Readmissions and emergency department visits are common following discharge, with many due to respiratory illness. Inhaled antibiotics are frequently prescribed to treat bacterial respiratory infection. However, guidelines for standardized management of tracheostomy-related respiratory illness are not available. Although standardized decannulation protocols are utilized, evidence-based guidelines are lacking, and the role of routine polysomnogram prior to decannulation is unresolved. Several knowledge gaps in management of pediatric tracheostomy present the opportunity for future research to improve patient outcomes., Competing Interests: Ms Willis is a section editor for Respiratory Care., (Copyright © 2024 by Daedalus Enterprises.)

- Abstract
The methods section of a manuscript is one of the most important parts of a research paper because it provides information on the validity of the study and credibility of the results. Inadequate description of the methods has been reported as one of the main reasons for manuscript rejection. The methods section must include sufficient detail so that others could repeat the study and reproduce the results. The structure of the methods section should flow logically and chronologically. There are multiple components of methods sections, including study design, materials used, study procedures, and data analysis. Each element must be adequately described and thoroughly detailed to provide an understanding of how the results were obtained and how to interpret the findings. Studies that involved humans or animals must include an ethics statement of approval from the appropriate governing body. The methods section should explain how subjects were identified and should state inclusion and exclusion criteria. All materials used to complete the study should be described in detail, including equipment, drugs, gases, chemicals, treatments, interventions, or other items. Study procedures should outline all steps taken to obtain the results and clearly state the outcome measures. Subheadings might be helpful for organizing the methods section into subsections when there is a considerable amount of information to report. A well-written methods section will guide the reader through the research process and provide adequate information to evaluate study validity and reproduce the work. The purpose of this paper is to provide guidance for writing the methods section of a manuscript., Competing Interests: Ms Willis is a Section Editor for Respiratory Care., (Copyright © 2023 by Daedalus Enterprises.)

- Abstract
Background: Caregivers of tracheostomized children must learn and demonstrate multiple tracheostomy care skills. At our hospital, caregiver education is provided through a combination of written instructions, classroom sessions, hands-on practice with a manikin, and bedside demonstration. As part of a quality improvement initiative, caregivers were provided a training doll to practice skills., Methods: A training doll was provided to caregivers of children within the first week of tracheostomy placement to practice skills. Two questionnaires were utilized during the education process to evaluate utility of the training dolls, skills practiced, and confidence in performing skills. The first questionnaire was completed at the time of the classroom session and the second questionnaire after training was completed. A chart review was conducted to compare outcomes for children whose caregivers did and did not receive a training doll., Results: Caregivers of 33 children with a tracheostomy received training dolls, and 28 were not provided dolls. The majority of caregivers felt the training doll was helpful for practicing skills (initial 93%, second questionnaire 85%). Some caregivers reported a lack of confidence in changing the tracheostomy tube (47%) and using a self-inflating bag (21%) in the initial questionnaire. Confidence increased for all skills in the second questionnaire. Few caregivers reported not using the training doll (initial 21%, second 11%). There were no significant differences in hospital length of stay (LOS) ( P = .21) or time to complete training ( P = .21) for children whose caregivers were and were not provided a doll., Conclusions: The majority of caregivers utilized the training doll to practice tracheostomy skills and found it helpful for training. The training doll did not significantly impact hospital LOS or time to complete training. Use of a training doll to practice tracheostomy skills is an additional tool to assist caregivers with learning required skills prior to discharge home., Competing Interests: Ms Willis is a section editor for Respiratory Care.

Willis LD
- Abstract
The next step following acceptance of an abstract submitted for a scientific meeting is to create the poster. Poster presentations provide an avenue for dissemination of research findings as well as the opportunity to highlight the work and network with other clinicians. Requirements for poster presentations vary among scientific meetings. Therefore, it is important to follow instructions set forth by the specific conference at which the work will be presented. Important considerations for poster design include the elements it should contain, font type and size, use of tables and figures, and poster size. Research indicates visual appeal has a greater influence in attracting attention than content. In addition to creating the poster, preparing for presentation is an essential step in the process. Practicing the presentation prior to the meeting, anticipating questions, and being familiar with the poster content are principal factors in preparing for the presentation. Oral presentations for posters are typically brief and should only focus on the key points. The purpose of this paper is to review poster design and provide general guidelines for presenting an abstract at a scientific meeting., (Copyright © 2023 by Daedalus Enterprises.)

Berlinski A and Willis LD
- Abstract
Background: Patients receiving mechanical ventilation often require airway clearance and inhaled therapies. Intrapulmonary percussive ventilation (IPV) combines a high-frequency percussive ventilator with a jet nebulizer. Data on aerosol delivery efficiency of the device are scarce. We evaluated albuterol delivery efficiency while using an IPV in-line adapter under different conditions., Methods: A pediatric lung model of invasive mechanical ventilation was used. The following independent variables were evaluated: lung condition (normal vs ARDS), ventilator mode (adaptive pressure ventilation vs pressure control), percent opening of adapter (0% vs 25% vs 50%), IPV driving pressure (25 psi vs 40 psi), IPV percussion setting (easy vs hard), and endotracheal tube (ETT) size (3.5 mm vs 5.5 mm). Albuterol delivery efficiency (mass captured in the filter expressed as percentage of loading dose) was selected as the dependent variable. Albuterol was captured on a filter at the tip of the ETT and quantified via spectrophotometry (276 nm)., Results: Albuterol delivery efficiency ranged from 0-2.89%. Median (interquartile range) and 95% CI around the median were 0.54% (0.37-1.00) and 0.50-0.63%, respectively. The coefficient of determination (R
2 ) for the model including all variables was 0.363. The 2 main contributors were percent of adapter opening (R2 0.30) and IPV setting (R2 0.039)., Conclusions: Albuterol delivery during invasive mechanical ventilation via in-line IPV in a pediatric lung model was inefficient. Alternative methods of delivering bronchodilators and other inhaled medications should be considered when IPV is used., (Copyright © 2023 by Daedalus Enterprises.)- Published

- Abstract
Background: Essential skills for respiratory therapists extend beyond the traditional scope of therapy. Respiratory therapists are expected to communicate effectively, deliver bedside education, and practice within interprofessional teams. Respiratory therapy entry-to-practice program accreditation standards require evaluation of student competence in communication and interprofessional practice. This study aimed to determine if entry into practice programs include curriculum and competency evaluation for oral communication, patient education, telehealth, and interprofessional activities., Methods: The primary objective was to identify the curriculum and method of competency evaluation. The secondary objective was to compare degree programs. Directors of accredited respiratory therapy programs were invited to complete an anonymous survey with regard to degree program type, oral communication, patient education, learning strategies, telehealth, and interprofessional activities. Degree programs were classified as associate's of science 2 year, associate's of science < 2 year, or bachelor's of science., Results: Of 370 invited programs, respondents in 136 programs (37%) completed the survey. Oral communication competence was evaluated by 82%. Patient education curriculum and competency evaluation were reported by 86% and 73%, respectively. Telehealth was rarely included or evaluated. Interprofessional activities were included by 74%, of whom 67% evaluated competency. Bachelor's of science programs were more likely to include a specific patient education course ( P = .004), evaluate oral communication competency with unpaid preceptors ( P = .036), and evaluate interprofessional competence through formal interprofessional programs ( P = .005). Associate's degree 2-year programs used laboratory proficiency for patient education competency evaluation more often than other programs ( P = .01). associate's of science < 2-year programs were more likely to include simulation experiences that involved motivational interviewing ( P = .01)., Conclusions: Differences exist among program types for curriculum and competency evaluation. Telehealth was rarely included or evaluated at any degree level. Programs should evaluate the need for enhanced patient education and telehealth instruction., Competing Interests: Ms Willis is a section editor for Respiratory Care.

- Abstract
Background: Best practice guidelines for asthma management recommend education and spirometry at specific intervals. A written asthma action plan with education and spirometry is ordered at the discretion of physicians at our institution. An initial chart review revealed that asthma education and spirometry were not consistently ordered in the pediatric primary care clinics. This quality improvement study aimed to increase frequency of spirometry and asthma education in children with asthma seen in pediatric primary care through use of a respiratory therapist (RT)-driven protocol., Methods: The protocol established that spirometry and education would be done annually for children ≥ 6 y of age with intermittent asthma and every 6 months for persistent asthma. RTs identified eligible subjects and placed the electronic medical record orders before the clinic visit. Physicians were invited to complete a questionnaire before and after protocol implementation to assess barriers and protocol satisfaction., Results: Nine hundred and thirty-two children were included. Prior to protocol implementation, spirometry and education were completed in 64.9% and 62.6% of eligible children, respectively. Following protocol implementation, spirometry and education were significantly increased to 92.7% ( P < .001) and 88.5% ( P < .001), respectively. Physicians identified interruption in clinic flow as the primary barrier for ordering spirometry and were satisfied with the protocol. Physicians stated that communication with RT improved through use of this protocol., Conclusions: Implementation of an RT-driven protocol in an out-patient pediatric primary care setting significantly increased utilization of spirometry and education for children with asthma. RTs working in the pediatric out-patient primary care setting played a vital role in achieving best practices for asthma management. The implementation of the protocol enhanced interdisciplinary communication., Competing Interests: Ms Willis is a section editor for Respiratory Care.

- Abstract
Background: Respiratory therapists (RTs) are in a unique position to positively impact patient outcomes through respiratory care research. Research plays a key role in evidence-based medicine; however, few RTs perform and publish research. Identification of barriers experienced by RTs may help increase RT-driven research. Thus, we aimed to identify barriers and research interests for RTs., Methods: American Association for Respiratory Care (AARC) members were invited to anonymously complete a survey via an electronic link posted on AARC Connect. Survey domains included research training, experience, reasons for doing research, important respiratory topics, and barriers to conduct research., Results: Responses from 82 surveys were analyzed. The majority were female (56%), and most had a graduate degree (61%), with a mean working experience of 25.3 ± 13.6 y. Fifty-seven percent of respondents reported at least one publication in a peer-reviewed journal. The desire to improve patient outcomes was the top-ranked reason for doing research. Most received research training through a graduate-level program (56%), but few had a formal research mentor (26%). Clinical research (67%) and quality improvement (63%) were the most common types of research. Data collection was the most common research role (51%). Invasive ventilation, advanced monitoring, and airway clearance were identified as the most important research topics. The primary barriers for RTs to conduct research were lack of protected time for research, opportunities to participate, training, departmental support, and mentorship., Conclusions: Lack of time, resources, and opportunities were identified as the primary barriers to RT research, and many RTs have not received formal research training. Resources such as formal mentorship, funding, and protected time may help increase RT participation in research., Competing Interests: Ms Willis, Mr Miller, and Dr Li are section editors for Respiratory Care.

- Abstract
An understanding of the research process is an essential skill for designing a study and developing the research protocol. Poor study design can lead to fatal flaws in research methodology, ultimately resulting in rejection for publication or limiting the reliability of the results. Following the steps of the research process and devising the research question and hypothesis prior to study initiation can avoid common problems encountered with research questions and study design. Formulating the research question is the first step in the research process and provides the foundation for framing the hypothesis. Research questions should be feasible, interesting, novel, ethical, and relevant (FINER). Application of the FINER criteria can assist with ensuring the question is valid and will generate new knowledge that has clinical impact. Utilization of the population, intervention, comparison, and outcome (PICO) format helps to structure the question as well as refine and narrow the focus from a broad topic. The hypothesis is derived from the research question and is used to determine the experiments or interventions that will answer the question. This aim of this paper is to provide guidance for developing research questions and forming a testable hypothesis through application of the FINER criteria and the PICO process., Competing Interests: Ms Willis is a section editor for Respiratory Care., (Copyright © 2023 by Daedalus Enterprises.)

- Abstract
Background: Regular care and cleaning of positive airway pressure (PAP) devices are important for maintaining equipment in the home. Illness and hospitalization have occurred from inadequate cleaning and use of tap water in the humidifier. In recent years, ozone and ultraviolent-light disinfection devices have been advertised for cleaning home PAP equipment. Our clinic provides instructions; however, cleaning practices performed in the home are unknown., Methods: A survey of home cleaning practices for PAP equipment was conducted in a pediatric sleep clinic during 2019-2020. Survey domains were method, cleaning and replacement frequency for each component, type of water used, instruction preferences, and demographics. The primary aim was to identify home PAP cleaning practices and compare with provided instructions. The secondary aim was to determine if respiratory-related symptoms (eg, congestion, runny nose, sneezing, coughing) occurred or increased with PAP use or inadequate cleaning., Results: The survey was completed by 96 respondents. Most reported weekly cleaning of mask (36, 38%), tubing (41, 43%), and humidifier (31, 33%) with soap and water as the primary method for each. The majority used distilled water in the humidifier (74, 77%) and reported respiratory symptoms did not occur with PAP use (64, 67%). Very few indicated a device was used to clean equipment. No associations were found between length of time for PAP use and cleaning practices. There was a moderately low correlation between age and cleaning. Increased age was associated with decreased cleaning frequency (r = 0.20, P = .048)., Conclusions: Care and cleaning practices of home PAP equipment varied from instructions provided in clinic. Most reported at least weekly cleaning of items for which daily cleaning is recommended. Few reported using a device for cleaning or having respiratory symptoms from PAP treatment., Competing Interests: Ms Willis is a section editor for Respiratory Care.

- Abstract
Background: Standardized acute asthma management with score-based, respiratory therapist (RT)-driven pathways and protocols improves outcomes including decreased length of stay (LOS) and time on continuous albuterol therapy. Limited data are available for the safety of continuous albuterol used outside of pediatric ICU (PICU). We use a modified pediatric asthma score (PAS) for the asthma pathway at our institution. The safety and effectiveness of using PAS to initiate/stop continuous albuterol as part of a score-based, RT-driven asthma pathway were evaluated., Methods: A retrospective review of children ≥ 2 y admitted for asthma exacerbation to the PICU and step-down unit who received continuous albuterol as part of the asthma pathway during 2017-2019 was completed. Demographic and clinical data were extracted including PAS, dose and duration of continuous albuterol, LOS, and complications. Outcomes of subjects admitted to the PICU and step-down unit were compared., Results: Results are expressed as median (interquartile range). The study included 412 children (61% male, 59.9% Black, 92.7% non-Hispanic, 44.9% moderate persistent asthma) with age and weight of 6.4 (4.0-10.0) y and 24.8 (17.3-39.5) kg, respectively. Most children were admitted to step-down unit (71.1%). Initial albuterol dose, duration, and LOS were 15 (10-20) mg/h, 9.1 (5.7-16.0) h, and 1.4 (0.9-2.3) d, respectively. Respiratory support was required by 29% of subjects. Need to restart therapy (2.9%), transfer to PICU (1.7%), and intubation (0.5%) were infrequent. No pneumothoraces or deaths were reported. Emergency department visits (3.9%) or readmissions (0.7%) within 30 d of discharge were low. Subjects admitted to the PICU were sicker and required more therapies and respiratory support than those admitted to the step-down unit., Conclusions: Use of an RT-driven, score-based pathway for initiation and discontinuation of continuous albuterol for treatment of pediatric asthma exacerbation was safe and effective in the PICU and step-down unit., Competing Interests: Dr Berlinski discloses relationships with Cystic Fibrosis Foundation, Mylan, National Institutes of Health, Therapeutic Development Network, Trudell Medical International, Vertex, and the International Pharmaceutical Aerosol Consortium on Regulation and Science.

- Abstract
Background: Obstructive sleep apnea (OSA) is diagnosed through polysomnography (PSG) testing and commonly treated with positive airway pressure (PAP). The initial recommended treatment for pediatric OSA is adenotonsillectomy, but when this is contraindicated or ineffective, PAP is the next option. Children followed in our pediatric sleep disorders center who are diagnosed with OSA and meet criteria for therapy are empirically prescribed a PAP device, usually auto-titrating PAP (APAP), to avoid delays in therapy. Titration PSG is performed later to assess adequacy of settings. The aims of this study were to determine how often PSG titration results in changes to empirically prescribed PAP and to assess adherence to therapy before and after PSG titration., Methods: A retrospective medical records review was completed for children diagnosed with OSA, prescribed PAP, and had a titration PSG within a 5-y consecutive period of 2008-2012. Demographic data, type of device, pressure settings, and adherence downloads were reviewed. Adherence was assessed before and after titration overall and compared for those who did and did not have therapy changes following titration., Results: The study included 121 participants. Median age at the time of the diagnostic PSG was 11 (interquartile range [IQR] 8-14) y. Most (106, 88%) were initially prescribed APAP. Median length of time between initial and follow-up PSG was 6.4 (IQR 4.4-10.1) months. The majority (94, 78%) had therapy changes following titration. Overall, adherence percentage > 4 h per night was not significantly increased post titration (P = .47). There were no statistically significant differences in adherence between those who had therapy changes and those who did not (P = .26)., Conclusions: Titration studies resulted in therapy modifications for most children. Adherence was not increased following the titration PSG. Changes in therapy did not result in increased adherence. Titration PSGs may optimize empirically prescribed settings., Competing Interests: Ms Willis serves as Section Editor for Respiratory Care.

- Abstract
Background: Face coverings are recommended to help mitigate the spread of COVID-19. Guidelines regarding face mask use have evolved from the time when COVID-19 first emerged. Practices for face mask use in the United States vary widely., Methods: Clinical and nonclinical staff from a pediatric health care system were invited to complete a survey regarding perceptions and practices of face mask use during the COVID-19 pandemic. Overall results were analyzed, and subgroup analyses were conducted to compare clinical and nonclinical staff, and clinical staff who do and do not provide direct patient care., Results: The response rate was approximately 24% (1,128 of 4,698). Most respondents were clinical staff who provide patient care. A surgical/procedure mask was most often worn for patient care by 72% ( P < .001). Most respondents (70%) reported wearing a cloth mask when not in the hospital ( P < .001). Cloth masks were worn for a mean of 3.4 ± 3.9 d before washing. Frequent hand hygiene before putting on the mask, before removing, and after removing was reported as 56%, 44%, and 62%, respectively. The most common challenges reported were glasses fogging (69%), skin irritations (45%), and headaches (31%). Qualitative data revealed themes of feeling unsafe, beliefs and practices about COVID-19 and masks, mandates and enforcement of wearing masks, availability of personal protective equipment, and care delivery challenges., Conclusions: Practices and perceptions of face masks varied among staff in a pediatric health care system. Some staff did not feel that masks are effective in preventing virus spread, and others did not feel safe in performing job duties. Hand hygiene for mask handling was not practiced consistently. A large number of staff reported having experienced challenges or health issues when wearing a mask. Clinical staff who provide direct patient care reported more issues than both nonclinical and clinical staff who do not provide care., Competing Interests: The authors have disclosed no conflict of interests., (Copyright © 2021 by Daedalus Enterprises.)

- Abstract
Advances in medicine and technology have led to improved survival rates of children with chronic respiratory disease such as cystic fibrosis, neuromuscular disease, and ventilator dependence. Survival into adulthood has created the need for adult specialists for conditions originating in childhood. Transition from pediatric to adult health care is a process that requires advanced planning and preparation and is not a one-time transfer event. Transition should be standard practice, but many children with special health care do not experience successful transition outcomes. Barriers to successful transition include lack of a standardized process, inadequate planning, and poor communication. Adverse outcomes have occurred in cases of abrupt or haphazard transfers. A successful transition process includes early introduction and ongoing discussion that engages the adolescent to plan and prepare for the eventual transfer of care. Care responsibilities should be gradually shifted from the parent to the adolescent in a manner appropriate for the adolescent's age and developmental status. Good communication and collaboration between pediatric and adult care teams is crucial to ensure a smooth transfer of care. Incorporating the 6 core elements of transition can be helpful in developing a successful transition program. This narrative review summarizes the literature for health care transition from pediatric to adult care including the rationale, barriers, factors associated with successful transition, and special considerations. The intent of this review is to increase clinician awareness of health care transitions and the components necessary for an effective transfer of young adults with chronic respiratory disease. Understanding the transition process is an important consideration for both pediatric and adult clinicians, including respiratory therapists., Competing Interests: Ms Willis has disclosed no conflicts of interest., (Copyright © 2020 by Daedalus Enterprises.)

- Abstract
Background: The transition from an ICU ventilator to a portable home ventilator (PHV) for children requiring long-term mechanical ventilation is a crucial step in preparing for discharge home and may not be successful on the first attempt. A review of this process at our institution revealed that some children required multiple trials before they were able to tolerate a PHV. A protocol was developed to standardize the transition process and reduce the number of failed attempts. Key features of the protocol included a transition readiness assessment and criteria for changing to the PHV., Methods: A retrospective chart review was completed to evaluate the process of changing to a PHV before and after the protocol was in place during the time period of 2011-2018. Primary outcome measures included the number of transition attempts and the length of time to achieve successful transition. A successful transition attempt was defined as the ability to tolerate a PHV for 14 d., Results: The study included 56 children ≤ 3 y old with a tracheostomy who required long-term ventilator support. The majority of subjects were from the neonatal ICU and had a diagnosis of bronchopulmonary dysplasia. There was a significant decrease in the number of attempts ( P = .005) and in the length of time ( P = .01) to successfully transition to a PHV for those who underwent the protocol., Conclusions: The process of changing from an ICU ventilator to a PHV in children requiring long-term mechanical ventilation was improved through the use of a standardized protocol. Both the number of failed attempts and the length of time to achieve successful transition were reduced when the protocol was applied. Further study is needed to evaluate other medical and nonmedical factors that may affect successful transition to a PHV., Competing Interests: The authors have disclosed no conflicts of interests., (Copyright © 2020 by Daedalus Enterprises.)

- Abstract
Background: Use of antibiotics to treat humans and animals is increasing worldwide, but evidence from low- and middle-income countries (LMICs) is limited. We conducted cross-sectional surveys in households and farms in Uganda to assess patterns of antibiotic use among humans and animals., Methods: Between May and December 2018, a convenience sample of 100 households in Nagongera (rural), 174 households in Namuwongo (urban) and 115 poultry and piggery farms in Wakiso (peri-urban) were selected and enrolled. Using the 'drug bag' method, participants identified antibiotics they used frequently and the sources of these medicines. Prevalence outcomes were compared between different sites using prevalence ratios (PRs) and chi-squared tests., Results: Nearly all respondents in Nagongera and Namuwongo reported using antibiotics to treat household members, most within the past month (74.7% Nagongera versus 68.8% Namuwongo, P = 0.33). Use of metronidazole was significantly more common in Namuwongo than in Nagongera (73.6% versus 40.0%, PR 0.54, 95% CI: 0.42-0.70, P < 0.001), while the opposite was true for amoxicillin (33.3% versus 58.0%, PR 1.74, 95% CI: 1.33-2.28, P < 0.001).Veterinary use of antibiotics within the past month was much higher in Wakiso than in Nagongera (71.3% versus 15.0%, P < 0.001). At both sites, oxytetracycline hydrochloride was the most frequently used veterinary antibiotic, but it was used more commonly in Wakiso than in Nagongera (76.5% versus 31.0%, PR 0.41, 95% CI: 0.30-0.55, P < 0.001)., Conclusions: Antibiotics are used differently across Uganda. Further research is needed to understand why antibiotics are relied upon in different ways in different contexts. Efforts to optimize antibiotic use should be tailored to specific settings., (© The Author(s) 2020.

- Abstract
Background: Therapeutic inhaled aerosols are often delivered to spontaneously breathing tracheostomized children. Although aerosol delivery can be affected by several factors, no recommendations for device/drug formulation choice are available. We hypothesized that practice modalities will vary among different institutions., Methods: The respiratory care departments in institutions in the United States that train pediatric pulmonologists were surveyed regarding their practices of delivering aerosols to spontaneously breathing tracheostomized children. Characteristics of the institution; use of metered-dose inhalers (MDIs), nebulizers, and dry powder inhalers; use of a resuscitation bag to aid aerosol delivery (assisted); types of medication used; and factors affecting choice of delivery method were recorded., Results: Of the invited institutions, 81% (38/47) participated, with 68% of them being freestanding children's hospitals. MDIs were used by 92% of the institutions surveyed, with similar use of unassisted (32%, with 83% of them using spacers), assisted (34%, with 100% of them using non-valved spacers), and both techniques (34%). Nebulizers were used by 97% of the institutions surveyed, with all using unassisted and 32% also using assisted technique. Tracheostomy aerosol mask was the most commonly used interface (89%). Assisted technique for either MDI or nebulizer was used by 68% of the institutions surveyed, with similar use of flow-inflating bag, self-inflating bag, and both devices. Types of inhaled medications utilized by surveyed institutions included aerosolized antibiotics (82%), corticosteroids (100%), short-acting β agonists (100%), combination therapy (32%), and mucolytics (84%). Dry powders were not used. Patient cooperation was the most frequent and single most important factor influencing the choice of delivery method., Conclusions: A wide variation in practice of delivering aerosols to spontaneously breathing tracheostomized children was noted. In-vivo and in-vitro studies are needed to support clinical recommendations.

- Abstract
An 11-year-old child with cerebral palsy required hospital admission for respiratory distress following administration of high-frequency chest wall compression (HFCWC). The child had severe neurologic impairment and an ineffective cough effort. HFCWC is effective in treating cystic fibrosis, but its use has not been widely studied in other diagnoses. Although highly effective in mobilizing mucus, HFCWC does not assist in removing airway secretions. In the absence of an effective cough, additional devices or techniques may be required.
