Addressing Administrative and System-Level Challenges to Implementation of Long-Acting Reversible Contraceptives in Adolescent Medicine and Pediatric and Adolescent Gynecology Practices: A Qualitative Study.

STUDY OBJECTIVE: Adolescents use long-acting reversible contraceptive (LARC) methods less than adults. Practices that specialize in adolescent medicine, including Adolescent Medicine (AM) and Pediatric and Adolescent Gynecology (PAG), may be well positioned to help improve adolescent access to these methods. We describe administrative and system-level barriers encountered when implementing LARCs for adolescents and strategies that practices have successfully used to address these barriers. DESIGN/SETTING/PARTICIPANTS: We conducted a qualitative study with physicians and staff at AM and PAG practices that provide LARCs to adolescents. INTERVENTIONS: Semi-structured telephone interviews MAIN OUTCOME MEASURES: Interview guides were based on the Consolidated Framework for Implementation Research (CFIR), an implementation science methodology designed to understand the following aspects of settings adopting new practices: innovation characteristics, external environment, institutional and practice settings, the stakeholders involved, and the implementation process. RESULTS: Seventeen interviews were performed. When examining administrative and system-level challenges encountered by interviewees, the four CFIR constructs identified most frequently were cost, readiness for implementation-available resources, planning, and engaging. Interviewees shared strategies used to overcome these common barriers, including for billing and working with insurance companies, space and equipment needed to introduce LARCs, scheduling and use of telemedicine, and staff training and engagement. CONCLUSION: Sites used many strategies to address these common challenges to implementation. Examples could help with implementation of LARC provision in practices serving adolescent populations.

Validating Lung Models Using the ASL 5000 Breathing Simulator.

OBJECTIVE: This study sought to validate pediatric models with normal and altered pulmonary mechanics. METHODS: PubMed and CINAHL databases were searched for studies directly measuring pulmonary mechanics of healthy infants and children, infants with severe bronchopulmonary dysplasia and neuromuscular disease. The ASL 5000 was used to construct models using tidal volume (VT), inspiratory time (TI), respiratory rate, resistance, compliance, and esophageal pressure gleaned from literature. Data were collected for a 1-minute period and repeated three times for each model. t tests compared modeled data with data abstracted from the literature. Repeated measures analyses evaluated model performance over multiple iterations. Statistical significance was established at a P value of less than 0.05. RESULTS: Maximum differences of means (experimental iteration mean - clinical standard mean) for TI and VT are the following: term infant without lung disease (TI = 0.09 s, VT = 0.29 mL), severe bronchopulmonary dysplasia (TI = 0.08 s, VT = 0.17 mL), child without lung disease (TI = 0.10 s, VT = 0.17 mL), and child with neuromuscular disease (TI = 0.09 s, VT = 0.57 mL). One-sample testing demonstrated statistically significant differences between clinical controls and VT and TI values produced by the ASL 5000 for each iteration and model (P < 0.01). The greatest magnitude of differences was negligible (VT < 1.6%, TI = 18%) and not clinically relevant. CONCLUSIONS: Inconsistencies occurred with the models constructed on the ASL 5000. It was deemed accurate for the study purposes. It is therefore essential to test models and evaluate magnitude of differences before use.
