Description of Respiratory Microbiology of Children With Long-Term Tracheostomies.

BACKGROUND: There is little evidence in the medical literature to guide empiric treatment of pediatric patients with long-term tracheostomies who present with signs and symptoms of a bacterial respiratory infection. The overall goal of this study was to describe the respiratory microbiology in this study population at our institution. METHODS: This study was a retrospective chart review of all subjects with tracheostomies currently receiving care at the Arkansas Center for Respiratory Technology Dependent Children. Descriptive statistics were used to describe the respiratory microbiology of the full study group. Several subgroup analyses were conducted, including description of microbiology according to time with tracheostomy, mean time to isolation of specific organisms after the tracheostomy tube was placed, association between Pseudomonas aeruginosa or methicillin-resistant Staphylococcus aureus isolation and prescribed antibiotic courses, and description of microbiology according to level of chronic respiratory support. Available respiratory culture results up to July 2011 were collected for all eligible subjects. Descriptive statistics were used to describe subject characteristics, and chi-square analysis was used to analyze associations between categorical data. P < .05 was considered statistically significant. RESULTS: A total of 93 subjects met inclusion criteria for the study. The median (interquartile range) age at time of tracheotomy was 0.84 (0.36-3.25) y, and the median (interquartile range) time with tracheostomy was 4.29 (2.77-9.49) y. The most common organism isolated was P. aeruginosa (90.3%), with Gram-negative organisms predominating. However, 55.9% of the study population had a respiratory culture positive for methicillin-resistant S. aureus. The first organism isolated after tracheostomy placement was Methiciliin-sensitive S. aureus was isolated the soonest after tracheostomy placement. Specific organisms were not related to level of chronic respiratory support or likelihood of receiving antibiotics. CONCLUSIONS: This study provides an updated overview of the variety of potential pathogens isolated from respiratory cultures of pediatric subjects with long-term tracheostomies.

Improving knowledge, technical skills, and confidence among pediatric health care providers in the management of chronic tracheostomy using a simulation model.

OBJECTIVE: The results from a recent national survey about catastrophic complications following tracheostomy revealed that the majority of events involved a loss of airway. Most of the events due to airway loss involved potentially correctable deficits in caregiver education. Training in a simulated environment allows skill acquisition without compromising patient safety. We assessed the knowledge and confidence level of pediatric health care providers at a large tertiary care children's hospital in routine and emergency tracheostomy care and evaluated the efficacy of a comprehensive simulation-based tracheostomy educational program. METHODS: The prospective observational study was comprised of 33 subjects including pediatric residents, internal medicine-pediatric residents, pediatric hospitalist faculty physicians, and advanced practice registered nurses who are involved in the care of patients with tracheostomies within a tertiary-care children's hospital. The subjects completed self-assessment questionnaires and objective multiple-choice tests before and after attending a comprehensive educational course that employed patient simulation. The outcome measurements included pre- and post-course questionnaires, pre- and post-course test scores, and observational data from the simulation sessions. RESULTS: Before the education and simulation, the subjects' comfort and confidence levels on a five-point Likert scale in performing routine tracheostomy tube care, routine tracheostomy tube change, and an emergency tracheostomy tube change were as follows (median (Q1, Q3)): 1 (1, 2), 1 (1, 2), and 1 (1, 2), respectively (n = 28). The levels of comfort and confidence after completing the course improved significantly to 4 (4, 5), 4 (4, 5), 4 (4, 5), respectively (P < 0.001) (n = 20). For the knowledge assessment, the pre-course test mean score was 0.53 ± 0.50, and the scores on the post-course test improved significantly with a mean score of 0.82 ± 0.39 (P < 0.001). During the educational intervention, specific deficiencies observed included a lack of understanding or familiarity with different types of tracheostomy tubes (e.g., cuffed versus uncuffed), physiological significance of the cuff, mechanism of action and physiological significance of the speaking valve, and the importance of the obturator in changing the tracheostomy tube. CONCLUSION: There is a need for improved tracheostomy education among pediatric health care providers. Incorporation of patient-simulation into a tracheostomy educational program was effective in improving knowledge, confidence, and skills.

Transition of respiratory technology dependent patients from pediatric to adult pulmonology care.

OBJECTIVE: Recent advances in medicine have allowed children with chronic life-threatening disorders to survive longer than ever before with the use of complex medical device technology (e.g., mechanical ventilation, dialysis, etc.). The care of children with chronic pulmonary disorders and respiratory-technology dependence is often complex, involving a high level of ongoing interaction between caregivers and the health care team. Unmanaged, non-standardized transition of respiratory technology dependent (RTD) patients to adult care potentially increases the risk of adverse outcomes. Pediatric Pulmonary programs at US children's hospitals were surveyed to ascertain whether a standardized process is utilized for transitioning RTD patients from pediatric to adult subspecialty pulmonology care. METHODOLOGY: Pediatric pulmonology programs with Accreditation Council for Graduate Medical Education certification were invited to participate in an electronic survey inquiring about practices and processes used to transition RTD patients from pediatric to adult pulmonology. RESULTS: The majority of respondents, 78.1% (25/32), reported that they do not utilize a standard protocol for transition while 41.4% (12/29) have no process in place. No program surveyed uses a designated transition leader. Referral to an adult pulmonologist within the same health system occurs more frequently than referral to private practice. Forty-three percent are not satisfied with involvement from the adult pulmonology care team. Coordination of care with other specialty services such as adult otolaryngology is provided by 31% of respondents. Of respondents, 13.8% assessed "readiness to transition" to adult pulmonary for RTD patients. Pediatric pulmonary providers are not satisfied with their current practices or involvement from the adult team, and only 24% track the transition process until the first visit with the adult pulmonologist. CONCLUSION: The survey results highlight a lack of standardized transition programs at US children's hospitals for the transfer of RTD patients from a pediatric to an adult care setting. Improvement in the standardized management of transitions of complex RTD patients from pediatric to adult care may decrease the risk for adverse health outcomes and the stresses associated with changing the health care setting.

The dirty bomb: management of victims of radiological weapons.

A "dirty bomb," a conventional explosive packed with radioactive material, kills or injures through the initial blast and by airborne radiation and contamination. Adult-health nurses need an understanding of the consequences of blast injuries and radiation exposure, and the management of victims.
