Impact of the pediatric tonsillectomy and polysomnography clinical practice guidelines

Impact of Clinical Practice Guidelines on Pediatric Tonsillectomy for Tonsillitis

OBJECTIVE

To determine the impact of the release of updated American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNSF) Clinical Practice Guidelines (CPG) for Tonsillectomy in Children in 2019 on adherence to evidence-based practice.

METHODS

Patients between ages 1 and 18 who had tonsillectomies and encounters for throat infection (tonsillitis or pharyngitis) between of February 5, 2015 and February 4, 2023 were identified by International Classification of Diseases and Current Procedural Terminology codes, excluding those with obstructive sleep-disordered breathing. Retrospective chart review was performed to determine adherence to evidence-based practice.

RESULTS

There was a significant increase in adherence to evidence-based practice post-CPG release compared to pre-CPG (85.4% vs 73.1%, P = .0088). There was an observed trend for improved adherence to evidence-based practice for pediatric tonsillectomy for recurrent infection for most of the post-CPG period. There were fewer tonsillectomies performed post-CPG, despite more total encounters for throat infection.

DISCUSSION

The publication of the updated AAO-HNSF CPG corresponded with improved adherence to evidence-based practice for tonsillectomy in children for recurrent infection and an observed decrease in overall rate of tonsillectomy. This suggests the CPG may be an effective quality improvement tool for reducing variation and unnecessary patient morbidity or harm.

IMPLICATIONS FOR PRACTICE

These findings suggest that the updated AAO-HNSF CPG for Tonsillectomy in Children may have effectively impacted practice patterns, and further work should be done to expand their reach to other specialties and settings. Consideration should also be given to further understand any balancing factors associated with reduced tonsillectomies for recurrent infections including quality of life impact on children managed expectantly.

Current Pediatric Tertiary Care Practices Following Adenotonsillectomy: An Update

OBJECTIVE

Adenotonsillectomy is a common procedure performed in children, and the practice patterns at academic centers have been evolving with the publication of updated societal guidelines. In this study, we assess perioperative practice patterns at tertiary care children's hospitals for children undergoing adenotonsillectomy.

METHODS

A cross-sectional 18-question survey distributed in July of 2022 recruited responses through August 25, 2022. The division chiefs of 70 pediatric otolaryngology groups at tertiary care children's hospitals across the United States and Canada were surveyed. Division chiefs submitted survey responses on behalf of the group practice patterns for children undergoing adenotonsillectomy. The main measure was survey responses from the division chiefs of pediatric otolaryngology reporting group practice.

RESULTS

The survey response rate was 46%. Eighty-eight percent of groups reported an official adenotonsillectomy admission policy. Commonly reported admission criteria included age (93%) and obesity (59%). Eighty-eight percent of groups defined severe obstructive sleep apnea as apnea-hypopnea index ≥10. Only 41% of groups required a child to be observed sleeping on room air prior to ambulatory discharge. Ninety-seven percent of groups reported routinely obtaining preoperative polysomnography in a variety of clinical settings.

CONCLUSIONS

Many children's hospitals report an official admission policy following adenotonsillectomy. Despite a decade passing since the initial publication of the American Academy of Otolaryngology-Head and Neck Surgery clinical practice guidelines, there remains great variability in the practice patterns for both preoperative polysomnography and postoperative monitoring and admission. These results highlight an opportunity for an improved unified approach to perioperative pediatric adenotonsillectomy practice.

Tonsillar-related pathologies: An analysis of the evidence underpinning management recommendations

OBJECTIVE

Evidence-based decision making is crucial in reducing the health and economic burdens imposed by tonsillar-related pathologies. Clinical practice guidelines are used to guide these decisions; however, uptake of recommendations in these guidelines is low. Systematic reviews are the highest level of evidence used to influence guideline recommendations; therefore, improving the reporting and methodological quality of systematic reviews related to tonsillar-related pathologies may improve guideline uptake and patient care.

METHODS

We used PubMed to search for all clinical practice guidelines related to tonsillar-related pathologies from 2010 to 2020. Included guidelines were then searched for all systematic reviews and meta-analyses. Study characteristics were extracted from each cited systematic review/meta-analysis before being evaluated using the PRISMA (Preferred Reporting Instrument for Systematic Reviews and Meta-Analyses) and AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews 2) instruments. We then compared systematic reviews conducted by a Cochrane systematic review group with non-Cochrane systematic reviews.

RESULTS

Seven clinical practice guidelines were included in our study and within these guidelines 98 SRs/MAs were cited, 80 of which were unique and included. Systematic reviews composed 9.1% (98/1082) of all guideline citations. Guideline PRISMA scores ranged from 0.47 to 0.83 with a mean score of 0.71 (n = 80) and guideline AMSTAR-2 scores ranged from 0.52 to 0.83 with a mean of 0.56 (7.29/13) and 0.75 (11.94/16) (n = 80). Cochrane systematic reviews displayed greater PRISMA (0.88 vs. 0.64: p < 0.001) and AMSTAR-2 (0.90 vs. 0.57; p < 0.001) scores compared to the non-Cochrane studies. We found PRISMA and AMSTAR-2 scores were positively correlated across guidelines (r = 0.93).

CONCLUSION

Wide variation exists in adherence to PRISMA and AMSTAR-2 guidelines among systematic reviews cited in clinical practice guidelines for tonsillar-related pathologies. Prior registration and adequate risk of bias assessment are two areas where improvements may be needed. Given the importance of guideline uptake, careful considerations to improve the methodological and reporting quality of evidence supporting tonsillar-related pathology recommendations are necessary.

Adherence to Subspecialty Guidelines in the Emergency Department

OBJECTIVES/HYPOTHESIS

The American Academy of Otolaryngology-Head and Neck Surgery has published clinical practice guidelines (CPGs) to guide management of common otolaryngologic (ENT) conditions. While these CPGs have been disseminated within specialty journals, many patients' first presentation of certain ENT complaints is to primary and acute care settings, including the emergency department (ED). It is less clear whether practice in these settings is concordant with specialty CPGs.

STUDY DESIGN

Retrospective cohort study.

METHODS

A retrospective review of medical records was performed at an academic tertiary care center with ED diagnoses of 1) Bell's palsy/facial weakness (BP) or 2) acute otitis externa (AOE) from May 2014-June 2018. Individual chart abstraction was performed for all encounters with these diagnoses for the purpose of assessing providers' adherence to CPGs.

RESULTS

During the study period, 224 patients were diagnosed with BP and 465 patients were diagnosed with AOE. Of the patients diagnosed with BP, 94% (n = 211/224) were prescribed oral steroids, concordant with guidelines, while 36% of these patients received head computed tomography (CT) scans and 43% received laboratory tests, counter to the guidelines. For those with a diagnosis of AOE, 28.6% received topical antibiotics only as primary treatment (n = 133/465) in accordance with guidelines while systemic antibiotics were prescribed in 42.2% (n = 196/465) discordant with the guidelines and 29.2% received both topical and systemic antibiotics (n = 136/465).

CONCLUSIONS

CPGs developed by subspecialty societies provide evidence-based recommendations for the care of patients with particular conditions, but may not be disseminated broadly outside of the specialty. Further research is required to understand the reasons behind divergent management of such conditions.

Clinician adherence to the clinical practice guideline: Acute otitis externa

OBJECTIVES/HYPOTHESIS

Over 10 years have passed since the Clinical Practice Guideline: Acute Otitis Externa (CPG-AOE) was first published, and it has been several years since its update. We sought to assess clinicians' adherence as well as referral patterns.

STUDY DESIGN

Survey.

METHODS

A 23-question survey was distributed to regional primary care clinicians evaluating demographic data, perception of the clinical practice guideline (CPG), adherence, and details of specialist referral. Statistical analysis was performed to compare adherence and referral patterns using the Fisher exact test or the χ2 test.

RESULTS

One hundred seventeen clinicians completed the survey. Fifteen respondents (12.8%) had reviewed the CPG. The recommendations with the least reported adherence were pain management (39.1%) and accounting for prior radiotherapy as a modifying factor (43.0%). The recommendations of prescribing ototopical therapy and avoiding systemic antimicrobials in uncomplicated acute otitis externa had adherence of 94.0% and 83.8%, respectively. When analyzed by provider type (e.g., resident, nurse practitioner/physician assistant), there were no significant differences in adherence. No significant differences in adherence were observed based on previous review of the CPG. When reporting frequency of specialist referral, the majority of respondents selected rarely (53.9%). The most favored reason for referral was symptoms >4 weeks (86.3%).

CONCLUSIONS

Of the providers who responded, very few had reviewed the CPG-AOE. Despite the added emphasis on pain management in the CPG update, this recommendation had the lowest adherence. Rates of adherence were similar across provider types and did not differ significantly if the CPG was reviewed. Efforts at improved provider education should be considered to increase adherence to the CPG.

Adherence to American Academy of Otolaryngology-Head and Neck Surgery Clinical Practice Guidelines: A Systematic Review

OBJECTIVE

Clinical practice guidelines synthesize and disseminate the best available evidence to guide clinical decisions and increase high-quality care. Since 2004, the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) has published 16 guidelines. The objective of this review was to evaluate clinicians' adherence to these guidelines' recommendations as measured in the literature.

DATA SOURCES

We searched PubMed, Embase, and Web of Science on August 29, 2019, for studies published after June 1, 2004.

REVIEW METHODS

We systematically identified peer-reviewed studies in English that reported clinician adherence to AAO-HNSF guideline recommendations. Two authors independently reviewed and abstracted study characteristics, including publication date, population, sample size, guideline adherence, and risk of bias.

RESULTS

The search yielded 385 studies. We excluded 331 studies during title/abstract screening and 32 more after full-text review. The remaining 22 studies evaluated recommendations from 8 of the 16 guidelines. The Otitis Media with Effusion, Polysomnography, Tonsillectomy, and Sinusitis guidelines were studied most. Study designs included retrospective chart reviews (7, 32%), clinician surveys (7, 32%), and health care database analyses (8, 36%). Studies reported adherence ranging from 0% to 99.8% with a mean of 56%. Adherence varied depending on the recommendation evaluated, type of recommendation, clinician type, and clinical setting. Adherence to the polysomnography recommendations was low (8%-65.3%). Adherence was higher for the otitis media with effusion (76%-90%) and tonsillectomy (43%-98.9%) recommendations.

CONCLUSIONS

Adherence to recommendations in the AAO-HNSF guidelines varies widely. These findings highlight areas for further guideline dissemination, research about guideline adoption, and quality improvement.

Differences in Tonsillectomy Use by Race/Ethnicity and Type of Health Insurance Before and After the 2011 Tonsillectomy Clinical Practice Guidelines

OBJECTIVE

To evaluate whether differences in pediatric tonsillectomy use by race/ethnicity and type of insurance were impacted by the American Academy of Otolaryngology-Head and Neck Surgery's 2011 tonsillectomy clinical practice guidelines.

STUDY DESIGN

We included children aged <15 years from Florida or South Carolina who underwent tonsillectomy in 2004-2017. Annual tonsillectomy rates within groups defined by race/ethnicity and type of health insurance were calculated using US Census data, and interrupted time series analyses were used to compare the guidelines' impact on utilization across groups.

RESULTS

The average annual tonsillectomy rate was greater among non-Hispanic white children (66 procedures per 10 000 children) than non-Hispanic black (38 procedures per 10 000 children) or Hispanic children (41 procedures per 10 000 children) (P < .001). From the year before to the year after the guidelines' release, tonsillectomy use decreased among non-Hispanic white children (-11.1 procedures per 10 000 children), but not among non-Hispanic black (-0.9 procedures per 10 000 children) or Hispanic children (+3.9 procedures per 10 000 children) (P < .05). Use was greater among publicly than privately insured children (75 vs 52 procedures per 10 000 children, P < .001). The guidelines were associated with a reversal of the upward trend in use seen in 2004-2010 among publicly insured children (-5.5 procedures per 10 000 children per year, P < .001).

CONCLUSIONS

Tonsillectomy use is greatest among white and publicly insured children. However, the American Academy of Otolaryngology-Head and Neck Surgery's 2011 clinical practice guideline statement was associated with an immediate decrease and change in use trends in these groups, narrowing differences in utilization by race/ethnicity and type of insurance.

Assessment of obstructive sleep apnoea (OSA) in children: an update

OSA is a condition characterised by episodes of complete or partial obstruction of the upper airway, associated with blood-gas changes and atypical sleep patterns. Early diagnosis of OSA may reduce the occurrence of systemic complications over time, although the diagnosis of OSA is, unfortunately, often late. The aim of the work is to review the current concepts in evaluation of paediatric obstructive sleep apnoea (OSA), with an updated revision of the literature considering risk factors, clinical manifestations, and basic and advanced assessment in the paediatric population. For this narrative review, PubMed, Embase and Cinahl databases were searched for the last 10 years, according to PRISMA criteria/guidelines. Assessment of paediatric OSA remains challenging and paediatric patients should always be carefully evaluated; polysomnography is the gold standard for diagnosis of paediatric OSA.

Impact of Clinical Guidelines on Revisits After Ambulatory Pediatric Adenotonsillectomy

BACKGROUND

Pediatric adenotonsillectomies are common and carry known risks of potentially severe complications. Complications that require a revisit, to either the emergency department or hospital readmission, increase costs and may be tied to lower reimbursements by federal programs. In 2011 and 2012, recommendations by pediatric and surgical organizations regarding selection of candidates for ambulatory procedures were issued. We hypothesized that guideline-associated changes in practice patterns would lower the odds of revisits. The primary objective of this study was to assess whether the odds of a complication-related revisit decreased after publication of guidelines after accounting for preintervention temporal trends and levels. The secondary objective was to determine whether temporal associations existed between guideline publication and characteristics of the ambulatory surgical population.

METHODS

This study employs an interrupted time series design to evaluate the longitudinal effects of clinical guidelines on revisits. The outcome was defined as revisits after ambulatory tonsillectomy for privately insured patients. Data were sourced from the Truven Health Analytics MarketScan database, 2008-2015. Revisits were defined by the most prevalent complication types: hemorrhage, dehydration, pain, nausea, respiratory problem, infection, and fever. Time periods were defined by surgeries before, between, and after guidelines publication. Unadjusted odds ratios estimated associations between revisits and clinical covariates. Multivariable logistic regression was used to estimate the impact of guidelines on revisits. Differences in revisit trends among pre-, peri-, and postguideline periods were tested using the Wald test. Results were statistically significant at P < .005.

RESULTS

A total of 326,993 surgeries met study criteria. The absolute revisit rate increased over time, from 5.9% (95% confidence interval [CI], 5.8-6.0) to 6.7% (95% CI, 6.6-6.9). The proportion of young children declined slightly, from 6.4% to 5.9% (P < .001). The proportion of patients having a tonsillectomy in an ambulatory surgery center increased (16.5%-31%; P < .001), as did the prevalence of obstructive sleep apnea (7.0%-14.0%; P < .001) and sleep-disordered breathing (20.6%-35.0%; P < .001). In a multivariable logistic regression model adjusted for age, sex, comorbidities, and surgical location, odds of a revisit increased during the preguideline period (0.4% increase per month; 95% CI, 0.24%-0.54%; P < .001). This monthly increase did not continue after guidelines (P = .002).

CONCLUSIONS

While odds of a postoperative revisit did not decline after guideline publication, there was a significant difference in trend between the pre- and postguideline periods. Changes in the ambulatory surgery population also suggest at least partial adherence to guidelines.

Diagnosis and perioperative management in pediatric sleep-disordered breathing

Sleep-disordered breathing has a prevalence of 12% in the pediatric population. It represents a spectrum of disorders encompassing abnormalities of the upper airway that lead to sleep disruption, including primary snoring, obstructive sleep apnea, central sleep apnea, and sleep-related hypoventilation. Sleep-disordered breathing is the most common indication for adenotonsillectomy, one of the most common procedures performed in children. In recent years, the American Academy of Otolaryngology-Head and Neck Surgery, American Academy of Pediatrics, and the American Society of Anesthesiologists have crafted guidelines to help safely manage children with sleep-disordered breathing. Each organization recommends in-laboratory polysomnography for definitive diagnosis of obstructive sleep apnea in certain cases. However, because this test is both costly and inconvenient, there has been significant interest in alternative methods for diagnosing clinically significant sleep-disordered breathing. Accurate diagnosis is critical because sleep-disordered breathing confers certain perioperative risks and increased mortality in some instances. Recent studies have elucidated the danger of anesthesia and opioids in worsening obstructive sleep apnea, and recommendations for alternative analgesia are being created. In addition, determining the most appropriate level and duration of monitoring in the postoperative period is actively being evaluated. This article presents an overview of the recent literature on the perioperative care of pediatric patients with sleep-disordered breathing. It highlights innovative modalities and limitations in diagnosing obstructive sleep apnea, the importance of a tailored anesthetic/analgesic approach to children with obstructive sleep apnea, and the need for postoperative monitoring. It also brings to focus that further studies on the perioperative care of these children are necessary.

Predictors of Obtaining Polysomnography Among Otolaryngologists Prior to Adenotonsillectomy for Childhood Sleep-Disordered Breathing

STUDY OBJECTIVES

(1) To assess the predictors for obtaining polysomnography (PSG) in children undergoing adenotonsillectomy (AT) for sleep-disordered breathing, and (2) to estimate the adherence to the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guideline recommendations for pre-AT PSG.

METHODS

This was a retrospective cohort study of children who were seen in the Pediatric Otolaryngology Clinic and underwent AT for sleep-disordered breathing over a 13-month period at a single tertiary care children's hospital. Patients with and without pre-AT PSG were compared using bivariate and logistic regression analysis to identify predictors for PSG. Electronic medical records were reviewed for demographic variables, medical comorbidities, and PSG data. Adherence to AAO-HNS guideline recommendations was estimated by calculating the proportion of patients who had a PSG among those who met the recommended criteria for pre-AT PSG.

RESULTS

Mean age was 6.6 ± 3.6 years with 53% male. A total of 65 of 324 children (20%) underwent PSG prior to AT. The only factor significantly associated with pre-AT PSG was age 1 to 3 years (odds ratio 4.5, 95% confidence interval [2.2, 9.0], P < .001). Among patients who met AAO-HNS criteria for pre-AT PSG, 28 of 128 (20%) underwent PSG compared to 35 of 186 (19%) who did not meet criteria (odds ratio 1.0, 95% confidence interval [0.6, 1.9], P = .87).

CONCLUSIONS

Among children who underwent AT, the only significant predictor of obtaining pre-AT PSG was age 1 to 3 years. The rate of adherence to the AAO-HNS guideline recommendations was low (20%), which represents an educational opportunity.

Are patients being evaluated for periprosthetic joint infection prior to referral to a tertiary care center?

Background

Patients with a painful or failed total joint arthroplasties should be evaluated for periprosthetic joint infection (PJI). The purpose of this study is to determine if patients referred to a tertiary care center had been evaluated for PJI according to the American Academy of Orthopaedic Surgeons (AAOS) clinical practice guidelines.

Methods

One hundred thirteen patients with painful hip (43) or knee (70) arthroplasties were referred to a single provider by orthopaedic surgeons outside our practice between 2012 and 2014. We retrospectively evaluated the workup by referring physicians, including measurement of serum erythrocyte sedimentation rate and C-reactive protein, performance of a joint aspiration if these values were abnormal, and obtainment of synovial fluid white blood cell count, differential, and cultures.

Results

Sixty-two of 113 patients (55%) did not have a workup that followed AAOS guidelines. Serum erythrocyte sedimentation rate and C-reactive protein were ordered for 64 of the 113 patients (57%). Of 25 patients with elevated inflammatory markers warranting aspiration, 15 (60%) had an aspiration attempted, with synovial fluid white blood cell, differential, and cultures obtained in 9 of 12 (75%) aspirations that yielded fluid. Of the 62 patients with an incomplete infection workup, 11 (18%) had a bone scan, 6 (10%) a computed tomography scan, and 3 (5%) a magnetic resonance imaging. Twelve of the 113 patients (11%) were ultimately diagnosed with PJI, with 5 undiagnosed prior to referral.

Conclusions

The AAOS guidelines to evaluate for PJI are frequently not being followed. Improving awareness of these guidelines may avoid unnecessary and costly evaluations and delay in the diagnosis of PJI.

Adherence to Swedish guidelines for pain treatment in relation to pediatric tonsil surgery: A survey of the multidisciplinary team

BACKGROUND

Pain management in children after tonsil surgery is essential, and optimal pain treatment has been discussed for many years. Data from the National Tonsil Register in Sweden (NTRS) and a national mapping have demonstrated the need for national pain treatment guidelines for pediatric tonsil surgery. As a result, Swedish national guidelines, together with updated patient information on the website tonsilloperation.se, were developed and implemented in 2013.

OBJECTIVES

The objective of this study was to evaluate the professionals' opinions of and adherence to pain treatment guidelines for pediatric tonsil surgery patients in a two-year follow-up.

METHOD

This descriptive cross-sectional study was based on data from an inter-professional questionnaire, which was validated by an expert group using a content validity index (S-CVI 0.93). The questionnaire was sent to all Swedish ear, nose and throat (ENT) departments (n = 49) that the NTRS identified as performing tonsil surgery on children younger than 18 years of age. In each clinic, we asked for responses from staff in each of the following professions: ENT physicians, anesthesia physicians, registered nurse anesthetists, and registered nurses in the ENT departments.

RESULTS

Respondents from 48 ENT departments participated, and 139/163 (85%) completed questionnaires were returned. The guidelines were reported as being clear, ensuring patient safety and providing optimal pharmacological treatment. Treatment was given according to the guidelines: Half of the departments gave pre- or intraoperative treatment with clonidine, betamethasone and high-dose paracetamol (acetaminophen). A multimodal pain approach (paracetamol and COX-inhibitors) after hospital discharge was prescribed by all departments after tonsillectomy and, extensively, after tonsillotomy. One-third of the departments prescribed paracetamol with a higher normal dose for the first three postoperative days. Half of the departments prescribed rescue analgesics, clonidine or opioids after tonsillectomy. None of the departments prescribed codeine or tramadol, drugs that are discouraged in the guidelines. The majority of the departments used the website tonsilloperation.se to provide information to the patients and their caregivers.

CONCLUSION

The respondents' opinions of and the ENT departments adherence to the Swedish national guidelines were considered to be good. The national implementation process in Sweden has impacted the manner in which ENT departments treat pain after tonsil surgery.

Adherence to Clinical Practice Guidelines

Clinical practice guidelines are designed to synthesize and disseminate the best available evidence to guide clinical practice. The goal is to increase high-quality care and reduce inappropriate interventions. Clinical practice guidelines that systematically review evidence and synthesize it into recommendations are important because the available scientific evidence is normally neither rapidly nor broadly incorporated into practice. It is important to understand and improve the impact of our American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guidelines on this uptake of scientific knowledge. Considering the barriers to guideline adherence is a central part of this. This understanding can guide clinicians, future guideline authors, and researchers when using guidelines, writing them, and planning clinically relevant research.

Acute care revisits after adenotonsillectomy in a pediatric Medicaid population in Ohio

INTRODUCTION

Guidelines for inpatient admission after pediatric tonsillectomy have been proposed to improve the safety of this procedure. This study examined the association between performing adenotonsillectomy in an inpatient setting and acute care revisits within 30 days among children enrolled in a Medicaid Accountable Care Organization in Ohio.

METHODS

The Accountable Care Organization's claims database was queried for adenotonsillectomies performed in children ages 0-18 years in 2008-2014. Procedures associated with an inpatient facility stay were classified as inpatient adenotonsillectomies. The primary outcome was emergency department visit or inpatient re-admission within 30 days. Secondary outcomes were revisits within 7 days and >7 days post-discharge. Logistic regression was used to test for association between inpatient procedure and need for revisits.

RESULTS

Adenotonsillectomies in 8835 girls and 7773 boys (age 6.8 ± 3.8 years) were analyzed, of which 842 (5%) were inpatient procedures. Revisits were required in 2511 (15%) cases and were primarily visits to the emergency department. In multivariable analysis, inpatient and outpatient procedures had comparable need for 30-day revisits (OR = 0.85; 95% CI: 0.69, 1.05; p = 0.124). In sub-analyses, inpatient adenotonsillectomy was associated with lower odds of early (≤7 days post-discharge; OR = 0.76; 95% CI: 0.58, 0.99; p = 0.045) but not later (≥8 days) revisits.

CONCLUSIONS

In a pediatric Medicaid population, inpatient adenotonsillectomy was not associated with greater odds of acute care revisits, compared to outpatient procedures. Appropriate risk stratification of children undergoing adenotonsillectomy can reduce the need for early acute care revisits by scheduling high-risk patients for prolonged observation.

Should obtaining a preoperative audiogram before tympanostomy tube placement be used as a quality metric? A survey of pediatric otolaryngologists

INTRODUCTION

Obtaining a preoperative audiogram prior to tympanostomy tube placement is recommended by the American Academy of Otolaryngology-Head and Neck Surgery clinical practice guideline (CPG): Tympanostomy tubes in Children, and this process measure is also used as a quality metric by payers. However, whether audiograms should be mandated in cases of tube placement for both chronic otitis media with effusion (COME) and recurrent acute otitis media (RAOM) is controversial. The objective of this study is to determine reports of practice patterns of pediatric otolaryngologists regarding obtaining audiograms before and after tympanostomy tube placement and opinions regarding utility of CPGs and use of this process measure as a quality metric.

METHODS

A 16-question cross-sectional survey of American Society of Pediatric Otolaryngology (ASPO) members was conducted. Per ASPO policy, no repeated requests or other enhanced response techniques were permitted. Independent t-tests for proportions were used to compare responses.

RESULTS

127 pediatric otolaryngologists completed the survey (response rate 26.9%). Nearly 70% of respondents reported being in practice for >10 years. 74% of respondents reported obtaining preoperative audiograms "always" or "most of the time" for COME, vs. 56.7% for RAOM (p < 0.0001). 76% agreed that obtaining a preoperative audiogram was representative of high quality for COME, vs. 52% for RAOM (p < 0.0001). 12% of respondents "completely agreed" that compliance with all aspects of CPGs represented high quality, while 68.8% responded that they somewhat agreed.

CONCLUSION

There is no consensus among pediatric otolaryngologists regarding the necessity of a preoperative audiogram in tympanostomy tube placement, especially for RAOM. Further evidence demonstrating the benefit of preoperative audiogram obtainment should be developed prior to inclusion as a guideline recommendation and as a quality metric.

Impact of Clinical Practice Guideline on the Treatment of Pediatric Femoral Fractures in a Pediatric Hospital

BACKGROUND

Clinical practice guidelines are being developed for a number of topics in medicine to decrease practice variability and to improve evidenced-based care. Within orthopaedic surgery, the American Academy of Orthopaedic Surgeons (AAOS) has a dedicated committee that produces these clinical practice guidelines on a variety of issues. One such issue was the treatment of pediatric diaphyseal femoral fractures, with the clinical practice guideline being published in 2009. We performed a retrospective review of the treatment of pediatric diaphyseal femoral fractures at a single institution from 2007 to 2012 to assess the clinical impact of this clinical practice guideline on the treatment of this condition.

METHODS

A retrospective review of all patients treated at a single pediatric hospital between 2007 and 2012 for a pediatric diaphyseal femoral fracture was conducted. The 2009 AAOS clinical practice guideline on the treatment of this condition was assessed and each patient record was analyzed to determine if the clinical practice guideline was followed, based on the age-specific recommendations. The percentage of treatment rendered adhering to the clinical practice guideline recommendations was compared in the pre-guideline group (prior to June 2009) and the post-guideline group (after June 2009).

RESULTS

A total of 361 patients were treated for a diaphyseal femoral fracture during this time frame and were included in this study. Overall, little change in treatment was found following the publication of this clinical practice guideline. The only significant change noted over this time period was a decrease (p = 0.03) in the percentage of patients between the ages of five and eleven years who were treated with flexible nails, at odds with this specific clinical practice guideline recommendation.

CONCLUSIONS

We found little direct clinical impact of the recently published AAOS clinical practice guideline on the treatment of pediatric diaphyseal femoral fractures. This analysis suggests an important role for clinical assessment after guideline publication to identify areas of potentially important future clinical research and to assess the utility of this guideline.

Association of National Guidelines With Tonsillectomy Perioperative Care and Outcomes

OBJECTIVE

To investigate the association of the 2011 American Academy of Otolaryngology Head and Neck Surgery guidelines with perioperative care processes and outcomes in children undergoing tonsillectomy.

METHODS

We conducted a retrospective cohort study of otherwise healthy children undergoing tonsillectomy between January 2009 and January 2013 at 29 US children's hospitals participating in the Pediatric Health Information System. We measured evidence-based processes suggested by the guidelines (perioperative dexamethasone and no antibiotic use) and outcomes (30-day tonsillectomy complication-related revisits). We analyzed rates aggregated over the preguideline and postguideline periods and then by month over time by using interrupted time series.

RESULTS

Of 111,813 children who underwent tonsillectomy, 54,043 and 57,770 did so in the preguideline and postguideline periods, respectively. Dexamethasone use increased from 74.6% to 77.4% (P < .001) in the preguideline to postguideline period, as did its rate of change in use (percentage change per month, -0.02% to 0.29%; P < .001). Antibiotic use decreased from 34.7% to 21.8% (P < .001), as did its rate of change in use (percentage change per month, -0.17% to -0.56%; P < .001). Revisits for bleeding remained stable; however, total revisits to the hospital for tonsillectomy complications increased from 8.2% to 9.0% (P < .001) because of an increase in revisits for pain. Hospital-level results were similar.

CONCLUSIONS

The guidelines were associated with some improvement in evidence-based perioperative care processes but no improvement in outcomes. Dexamethasone use increased slightly, and antibiotic use decreased substantially. Revisits for tonsillectomy-related complications increased modestly over time because of revisits for pain.
