RESUMEN
OBJECTIVE: To assess the reliability and construct validity of the Penetration-Aspiration Scale in children. STUDY DESIGN: This was a retrospective cohort study of pre- and postoperative video modified barium swallow studies from children who underwent interarytenoid injection augmentation for unexplained persistent pharyngeal dysphagia. Two pediatric speech and language pathologists reviewed each study twice in a blinded and randomized fashion. SETTING: Tertiary academic pediatric hospital. SUBJECTS AND METHODS: Thirty children were identified with adequate pre- and postoperative modified barium swallow studies within 4 weeks of intervention. Children were separated into clinical outcome groups based on ability to advance to thinner diet consistencies postoperatively. Construct validity was assessed with a mixed linear model to test the hypothesis that only the clinically improved group would receive better Penetration-Aspiration Scale scores after surgery. Reliability was assessed by calculating chance-corrected agreement between raters (interrater) and raters' repeat evaluations (intrarater). RESULTS: Inter- and intrarater reliabilities (Cohen's κ) were both excellent. Results of the mixed model revealed a significant interaction between outcome group and pre- and postoperative time interval. As hypothesized, this involved a significant improvement in Penetration-Aspiration Scale score only in the improved group. CONCLUSIONS: These findings suggest that the Penetration-Aspiration Scale is a reliable and valid measure of clinical response to interarytenoid injection augmentation in children.

OBJECTIVES: The clinical significance of the interarytenoid mucosal height (IAMH) in pediatric dysphagia, ranging from normal anatomy to a laryngeal cleft, is unknown. This study seeks to evaluate a cohort of patients who underwent evaluation of their IAMH during microdirect laryngoscopy (MDL) for associations between IAMH and dysphagia as diagnosed on preoperative videofluoroscopic swallow study (VFSS). METHODS: A retrospective case series of 1,351 patients who underwent MDL between 2011 and 2016 were reviewed for intraoperative evaluation of IAMH using our interarytenoid assessment protocol. After exclusions, 182 patients were divided into three groups: 1) thickened diet: VFSS with recommendation for thickened liquids (n = 82 of 182; 45.1%), 2) normal diet: VFSS with allowance of thin liquids (n = 19 of 182; 10.4%), and 3) control: no VFSS performed (n = 81 of 182; 44.5%). RESULTS: There was no difference in IAMH between groups (P = 0.35). Power analysis was able to achieve > 80% power to detect an effect size of ≥ 0.5 (1-5 mucosal height scale). The majority of patients in each group had an IAMH above the false vocal folds (thickened diet: 57.3%, normal diet: 57.9%, control: 64.2%). There were similar percentages of patients in each group with an IAMH at or below the true vocal folds (thickened diet: 4.9%, normal diet: 5.3%, control: 6.1%). CONCLUSION: There was no significant association between IAMH and preoperative thickened liquid recommendation in this cohort. This data fails to support the hypothesis that the IAMH is an independent etiological factor for pediatric pharyngeal dysphagia. Further studies comparing IAMH with outcomes after feeding therapy and surgery may better clarify this relationship between anatomy and physiology. LEVEL OF EVIDENCE: 4.

OBJECTIVES/HYPOTHESIS: Given the costs of healthcare, capitation, and desires for quality improvement (QI), there is a need to better assess healthcare value. Time-driven activity-based costing and the Quadruple Aim have evaluated value by assessing health outcomes and provider experiences relative to costs. The proposed OPPS/Cost method expands on this to examine value for aerodigestive clinic treatment of pediatric persistent pharyngeal dysphagia: O + P1 + P2 + S/Cost (O = objective health [video-fluoroscopic swallow study results], P1 = patient/family experience [Consumer Assessment of Healthcare Providers and Systems], P2 = provider experience [Copenhagen Burnout Inventory {CBI}], S = subjective health [Feeding/Swallowing-Impact Survey], C = cost [time-driven activity-based costing]). STUDY DESIGN: Use of QI time data, surveys, and retrospective chart review for 56 patient encounters. METHODS: Staff interviews were used to develop process maps, and monetary values were assigned to activities. OPPS/Cost outcomes were normalized amongst variables, and composite values were calculated. Comparisons were made using a Student t test for pre- and postclinic relocation over a 14-month period. RESULTS: Time reductions were check-in (13 minutes/patient), rooming (21 minutes/patient), and providers (4 minutes/patient). Patient in-room wait time increased (4 minutes/patient). The CBI identified burnout as an area for improvement. OPPS/Cost composite values increased by 14%, with a 1.7% cost reduction, improvement in objective and subjective health outcomes of 47.4% (P < .05) and 7.3%, respectively, and stable patient/family experience. CONCLUSIONS: OPPS/Cost is feasible in an interdisciplinary clinic and helped evaluate value during a clinic relocation. The QI opportunities identified are indicative of the potential of OPPS/Cost.
