Advanced practice providers and children's hospital-based pediatric otolarynology practices.

INTRODUCTION: Advanced practice providers (APPs), including nurse practitioners and physician assistants, have been deployed in children's hospital-based academic pediatric otolaryngology practices for many years. However, this relationship in terms of prevalence, roles, financial consequences and satisfaction has not been examined. The objective of this study is to explore how APPs impact healthcare delivery in this setting. METHODS: Pediatric otolaryngology chiefs of all academic children's hospitals in the US were electronically surveyed about the ways APPs intersected clinically and financially in their respective practice. RESULTS: A total of 29 of 36 children's hospital-based pediatric otolaryngology practices completed the survey, of which 26 practices (90%) utilized APP. There were large variances within the APP practice cohort in faculty size (mean/median/range = 9.4/8.5/3-29); annual patient visits (mean/median = 18,373/17,600); number of practice site (mean/median/range = 4.3/4/2-9) and number of outpatient APP (mean/median/range = 6.3/5/1-30). No factors (faculty size, annual visits and number of practice sites) differentiated between the APP and non-APP practices. Among APP practices, significant correlation (p<.00001) was observed between size of APP cohort to faculty size and annual visits. 69% of the practices did not differentiate job functions of nurse practitioners and physician assistants. 85% of the practices utilized APPs in all practice sites and 19% utilized APPs in the operating room. 77% of APPs billed independently and 46% had on-site supervision. The most prevalent APP salary bracket based on 0-5, 6-10 and > 11 years of tenure were $76-100K (65%), $100-150K (77%) and $100-150K (86%), respectively. In 46% of the practices, APPs were able to generate enough revenue to cover more than 75% of their salary and 23% of practices generated a profit. 81% of the chiefs ranked the effectiveness of APPs as high (4 and 5) on a 5-point Likert scale. DISCUSSION: The majority of academic pediatric otolaryngology practices employed APPs. Despite the diversity seen in practice complexity, APP functionality and financial impact, most found the APP model to be beneficial in improving patient care, patient access and faculty productivity.

Risk indicators for congenital and delayed-onset hearing loss.

OBJECTIVE: To evaluate risk indicators for congenital and delayed onset hearing loss in a cohort of newborns who underwent newborn hearing screening, and to evaluate the impact of use of the Joint Committee on Infant Hearing (JCIH) recommendations on requirements for ongoing monitoring of infants identified as at risk for hearing loss. PATIENTS AND METHODS: Cohort of 26,341 newborns entered in a prospectively collected database as part of the University of Michigan Universal Newborn Hearing Screening program, with 90 patients identified. Logistic regression analysis was used to evaluate putative risk indicators for congenital and delayed onset hearing loss. An estimate of the cost burden of ongoing monitoring imposed by the use of differing risk indicators was performed. RESULTS: After controlling for the impact of other risk indicators, intensive care unit length of stay greater than 5 days and exposure to loop diuretics are not associated with an increased risk of congenital or delayed onset hearing loss. Inclusion of these risk indicators as a requirement for ongoing audiologic monitoring results in a high monitoring cost per additional case identified. DISCUSSION: This study confirms that the majority of the risk indicators currently recommended by the JCIH are effective at identifying infants at increased risk of congenital and delayed onset hearing loss. However, use of neonatal intensive care unit length of stay greater than 5 days and exposure to ototoxic medications are associated with small gains in the number of infants correctly identified as at risk of hearing loss. Further evaluation of the utility of these risk indicators, preferably with a diversity of patient population and healthcare settings, is warranted.

Pediatric deep space neck infections in U.S. children, 2000-2009.

OBJECTIVE: Deep space neck infections (DNI) are common pediatric illnesses, which can lead to significant morbidity and healthcare expenditures. Recent studies suggest that the incidence of pediatric DNI in the United States is increasing, but no nationally representative studies exist. This study sought to characterize pediatric DNI at the national level over the past decade and to determine whether U.S. incidence of pediatric DNI and associated resource utilization changed from 2000 to 2009. METHODS: The Kids' Inpatient Database (KID) was used to evaluate pediatric DNI incidence, demographics, and outcomes from 2000 to 2009. Cases were identified using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes for peritonsillar abscess (475), parapharyngeal abscess (478.22), and retropharyngeal abscess (478.24). Regression analyses within each year and across the entire study period were performed on variables of interest including performance of imaging studies, operative intervention, length of hospital stay and total hospital charges. RESULTS: The incidence of retropharyngeal abscess increased significantly from 0.10 cases per 10,000 in 2000 to 0.22 in 2009 (p=0.02). There was no significant change during this time period in the incidence of combined DNI (1.07-1.37 cases per 10,000, p=0.07), peritonsillar abscess (0.82-0.94 cases per 10,000, p=0.12) or parapharyngeal abscess (0.08-0.14 cases per 10,000, p=0.13). The percentage of retropharyngeal abscess patients managed surgically decreased (48-38%, p=0.04) and the average length of hospital stay also decreased during this time (4.6-3.9 days, p=0.03). There was a marked increase in the total inflation-corrected hospital charges per case for all DNI ($9,486-16,348, p=0.005). CONCLUSIONS: The incidence of pediatric retropharyngeal abscess has increased significantly from 2000 to 2009, without concurrent increases in the incidence of combined DNI, peritonsillar, or parapharyngeal abscesses. There has been a change in management of retropharyngeal abscesses during this time with a decrease in operative intervention and a decrease in the length of hospital stay. Hospital charges associated with all pediatric DNI have nearly doubled during this timeframe, warranting future epidemiologic resource utilization studies in this population.

Blinded evaluation of interrater reliability of an operative competency assessment tool for direct laryngoscopy and rigid bronchoscopy.

OBJECTIVES To confirm interrater reliability using blinded evaluation of a skills-assessment instrument to assess the surgical performance of resident and fellow trainees performing pediatric direct laryngoscopy and rigid bronchoscopy in simulated models. DESIGN Prospective, paired, blinded observational validation study. SUBJECTS Paired observers from multiple institutions simultaneously evaluated residents and fellows who were performing surgery in an animal laboratory or using high-fidelity manikins. The evaluators had no previous affiliation with the residents and fellows and did not know their year of training. INTERVENTIONS One- and 2-page versions of an objective structured assessment of technical skills (OSATS) assessment instrument composed of global and a task-specific surgical items were used to evaluate surgical performance. RESULTS Fifty-two evaluations were completed by 17 attending evaluators. The instrument agreement for the 2-page assessment was 71.4% when measured as a binary variable (ie, competent vs not competent) (κ = 0.38; P = .08). Evaluation as a continuous variable revealed a 42.9% percentage agreement (κ = 0.18; P = .14). The intraclass correlation was 0.53, considered substantial/good interrater reliability (69% reliable). For the 1-page instrument, agreement was 77.4% when measured as a binary variable (κ = 0.53, P = .0015). Agreement when evaluated as a continuous measure was 71.0% (κ = 0.54, P < .001). The intraclass correlation was 0.73, considered high interrater reliability (85% reliable). CONCLUSIONS The OSATS assessment instrument is an effective tool for evaluating surgical performance among trainees with acceptable interrater reliability in a simulator setting. Reliability was good for both the 1- and 2-page OSATS checklists, and both serve as excellent tools to provide immediate formative feedback on operational competency.

Pathologic evaluation of routine pediatric tonsillectomy specimens: analysis of cost-effectiveness.

OBJECTIVE: Evaluate the utility and explore the cost-effectiveness of mandatory gross or pathologic analysis of routine tonsillectomy specimens in children. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care children's hospital. SUBJECTS AND METHODS: Retrospective case series of results of pathologic analysis of tonsillectomy specimens from all pediatric patients who underwent tonsillectomy between 1996 and 2008 (n = 5235). The results of pathologic evaluation of routine and nonroutine specimens were evaluated, and an economic analysis of alternative methods of specimen handling was performed. RESULTS: Zero cases of unsuspected pathology were identified on planned gross specimen evaluation (n = 4186), resulting in an estimated prevalence of 0 to 0.00088 (95% confidence interval [CI]). Positive pathologic findings on microscopic analysis (n = 1066) were only identified in posttransplant patients (10/63; 95% CI, 0.079-0.27) and cases of surgeon suspicion (8/78; 0.045-0.19). No cases were identified among the 17 undergoing microscopic pathologic analysis on the basis of pathologist suspicion on gross evaluation (95% CI, 0-0.20). From an economic standpoint, microscopic evaluation of routine pediatric tonsillectomy specimens appears to be superior to gross evaluation but with an estimated cost of $766,500 per case of unsuspected lymphoma identified. CONCLUSIONS: This study identifies a very low prevalence of unsuspected pathology on gross pathologic analysis of routine tonsillectomy specimens in children. Exploration of the cost implications suggests that such a practice is not a cost-effective use of limited health care resources. Microscopic examination is appropriate for posttransplantation patients and in cases of surgeon suspicion.
