Safety of day-case paediatric tonsillectomy in England: an analysis of administrative data for the Getting It Right First Time programme.

We used the Hospital Episodes Statistics database to investigate unwarranted variation in the rates Trusts discharged children the same day after scheduled tonsillectomy and associations with adverse postoperative outcomes. We included children aged 2-18 years who underwent tonsillectomy between 1 April 2014 and 31 March 2019. We stratified analyses by category of Trust, non-specialist or specialist, defined as without or with paediatric critical care facilities, respectively. We adjusted analyses for age, sex, year of surgery and aspects of presentation and procedure type. Of 101,180 children who underwent tonsillectomy at non-specialist Trusts, 62,926 (62%) were discharged the same day, compared with 24,138/48,755 (50%) at specialist Trusts. The adjusted proportion of children discharged the same day as tonsillectomy ranged from 5% to 100% at non-specialist Trusts and 9% to 88% at specialist Trusts. Same-day discharge was not independently associated with an increased rate of 30-day emergency re-admission at non-specialist Trusts but was associated with a modest rate increase at specialist Trusts; adjusted probability 8.0% vs 7.7%, odds ratio (95%CI) 1.14 (1.05-1.24). Rates of adverse postoperative outcomes were similar for Trusts that discharged >70% children the same day as tonsillectomy compared with Trusts that discharged <50% children the same day, for both non-specialist and specialist Trust categories. We found no consistent evidence that day-case tonsillectomy is associated with poorer outcomes. All Trusts, but particularly specialist centres, should explore reasons for low day-case rates and should aim for rates >70%.

The Surgical Treatment of Peritonsillar Abscess: A Retrospective Analysis in 584 Patients.

OBJECTIVES: There are three surgical treatment options for patients with peritonsillar abscess (PTA): needle aspiration, incision and drainage (ID), and abscess tonsillectomy (ATE). The updated German national guideline (2015) included changes in the treatment of PTA. The indication for tonsillectomy (TE) in patients became more stringent and preference was given to ID in certain cases. STUDY DESIGN: Retrospective analysis. METHODS: We performed a retrospective systematic analysis of patient data using the in-house electronic patient records and considered a 4-year period from 2014 to 2017. About 584 patients were identified. Our aim was to analyze the influence of the updated guideline on clinical practice. RESULTS: 236 of 584 patients (40.4%) underwent ATE with contralateral TE. In 225 patients (38.5%), unilateral ATE was performed. Mean surgery time was significantly shortened when only unilateral ATE was performed. Concerning postoperative bleeding, we noted a tendency toward a lower incidence after ATE in comparison to ATE with contralateral TE. Less than 1% of patients who underwent ATE had to be revised surgically due to postoperative hemorrhage. After the revision of the guideline, unilateral ATE and ID were conducted more frequently. CONCLUSION: These results support that ATE in an inpatient setting is a considerably safe and effective primary therapeutic option. ID represents a favorable treatment option for patients with PTA and comorbidities, nevertheless, patient compliance is required and insufficient drainage or recurrence of PTA may occur. The revision of the guideline had a significant impact on the choice of interventions (P < .001), which is reflected by the increased number of unilateral ATE.

Reduction in Pediatric Ambulatory Adenotonsillectomy Length of Stay Using Clinical Care Guidelines.

OBJECTIVE: Standardization of postoperative care using clinical care guidelines (CCG) improves quality by minimizing unwarranted variation. It is unknown whether CCGs impact patient throughput in outpatient adenotonsillectomy (T&A). We hypothesize that CCG implementation is associated with decreased postoperative length of stay (LOS) in outpatient T&A. METHODS: A multidisciplinary team was assembled to design and implement a T&A CCG. Standardized discharge criteria were established, including goal fluid intake and parental demonstration of medication administration. An order set was created that included a hard stop for discharge timeframe with choices "meets criteria," "4-hour observation," and "overnight stay." Consensus was achieved in June 2018, and the CCG was implemented in October 2018. Postoperative LOS for patients discharged the same day was tracked using control chart analysis with standard definitions for centerline shift being utilized. Trends in discharge timeframe selection were also followed. RESULTS: Between July 2015 and August 2017, the average LOS was 4.82 hours. This decreased to 4.39 hours in September 2017 despite no known interventions and remained stable for 17 months. After CCG implementation, an initial trend toward increased LOS was followed by centerline shifts to 3.83 and 3.53 hours in March and October 2019, respectively. Selection of the "meets criteria" discharge timeframe increased over time after CCG implementation (R2  = 0.38 P = .003). CONCLUSIONS: Implementation of a CCG with standardized discharge criteria was associated with shortened postoperative LOS in outpatient T&A. Concurrently, surgeons shifted practice to discharge patients upon meeting criteria rather than after a designated timeframe. LEVEL OF EVIDENCE: NA Laryngoscope, 131:2610-2615, 2021.

Can Tonsillectomy Be Safely Performed by Residents? A Comparative Retrospective Study.

OBJECTIVE: To assess whether a surgeon's level of training is associated with outcomes in pediatric tonsillectomy. DESIGN: A retrospective cohort study of the outcomes of pediatric tonsillectomies performed between 2006 and 2016 by senior surgeons versus resident surgeons under the supervision of senior surgeons. SETTING: An otolaryngology department in a tertiary academic hospital. PATIENTS: Children younger than 18 years who underwent bilateral tonsillectomy with or without adenoidectomy. MAIN OUTCOME MEASURES: Intraoperative bleeding, initiation of oral intake, and intraoperative and postoperative complications. RESULTS: Of 785 children, 397 (50.5%) were operated on by a resident surgeon and 388 (49.5%) by a senior surgeon. Patient demographics and surgical techniques were similar between the groups. The mean surgical time was 33.2 minutes in the residents' group and 27.1 minutes in the seniors' group (P = .032). The groups were similar in intraoperative bleeding, while same-day initiation of oral intake was 71% for children in the residents' group versus 61% in the seniors' group (P = .28). Reports of postoperative bleeding necessitating readmission and revised operations were similar for both groups (3.0% and 0.7%, respectively, in the residents' group; and 2.5% and 1.0%, respectively, in the seniors' group). CONCLUSION: Children undergoing tonsillectomy showed similar short-term outcomes, whether the operations were performed by a senior surgeon or a resident surgeon supervised by an attending surgeon. This study demonstrates the safety of pediatric tonsillectomy performed by resident surgeons supervised by attending physicians.

Impact of Diabetes Mellitus Following Tonsillectomy in Adults: A National Surgical Quality Improvement Program Analysis.

OBJECTIVES: To identify 30-day complication rates specific to patients with diabetes mellitus following tonsillectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing tonsillectomy between 2005 and 2018. Patients were stratified into 3 cohorts: insulin-dependent diabetes mellitus (IDDM), non-insulin-dependent diabetes mellitus (NIDDM), and non-diabetes mellitus (NODM). Coarsened-exact-matching was utilized to account for baseline differences between cohorts. Outcomes studied included post-operate complications, prolonged hospitalization, and unplanned readmissions. RESULTS: A total of 986 DM and 26 774 NODM patients were included, and the mean age of patients undergoing tonsillectomy was 29.5 ± 11.6 and 28.7 ± 11.0 years, respectively. The majority of patients were female (70.5% for both DM and NODM cohorts) and White/Caucasian (89.2% vs 89.3%). Among patients undergoing tonsillectomy, a greater proportion of DM patients experienced an operative time greater than or equal to the 75th percentile (35 minutes; 25.9% vs 22.8%, P = .024), overall morbidity (12.6% vs 5.4%, P < .001), pneumonia (0.6% vs 0.2%, P = .036), and reoperation (10.2% vs 3.5% P < .001) in comparison to NODM patients. In an analysis between IDDM (n = 379) and NIDDM (n = 211) patients, IDDM patients were at an increased risk for prolonged hospitalization (1.4% vs 0.0%, P = .045), pneumonia (5.2% vs 0.5%, P < .001), urinary tract infections (3.3% vs 0.3% P = .004), major complications (15.6% vs 7.7%, P = .002), minor complications (19.9% vs 8.2%, P < .001), and overall complications (10.0% vs 1.3%, P < .001). CONCLUSION: DM patients are at a heightened risk for complications following tonsillectomy. Standardized protocols, careful pre-operative planning, and stringent glycemic management may help optimize patient outcomes.

The embodiment of practice thresholds: from standardization to stabilization in surgical education.

Surgeons practice their own variations on a procedure. Residents experience shifting thresholds between variations that one surgeon holds firmly as principle and another takes more lightly as preference. Such variability has implications for surgical education, but the impact is not well understood. This is a critical problem to investigate as programs seek to define procedures for competency-based medical education (CBME) and improve learning through deliberate practice. Our study analyzes the emergence of procedural variation in an early-adopter CBME program through a situational analysis of tonsillectomy, a foundation level procedure in this otolaryngology, head and neck surgical program. An earlier phase of the study identified frequent variations (n = 12) on tonsillectomy among co-located surgeons who routinely perform this procedure (n = 6). In the phase reported here we interviewed these surgeons (n = 4) and residents at different stages of training (n = 3) about their experiences of these variations to map the relations of contributing social and material actors. Our results show that even a basic procedure resists standardization. This study contributes a sociomaterial grounded theory of surgical practice as an embodied response to conditions materialized by intra-relations of human and more-than-human actors. Shifting root metaphors about practice in surgical education from standardization to stabilization can help residents achieve stable-for-now embodiments of performance as their practice thresholds continue to emerge.

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.

The impact of new evidence on regional variation in paediatric tonsillectomy and adenoidectomy: a historical review.

BACKGROUND: Tonsillectomy and adenoidectomy have been among the most commonly performed procedures in children for approximately 100 years. These procedures were the first for which unwarranted regional variation was discovered, in 1938. Indications for these procedures have become stricter over time, which might have reduced regional practice variation. METHODS: This paper presents a historical review on practice variation in paediatric tonsillectomy and adenoidectomy rates. Data on publication year, region, level of variation, methodology and outcomes were collected. RESULTS: Twenty-one articles on practice variation in paediatric tonsil surgery were included, with data from 12 different countries. Significant variation was found throughout the years, although a greater than 10-fold variation was observed only in the earliest publications. CONCLUSION: No evidence has yet been found that better indications for tonsillectomy and adenoidectomy have reduced practice variation. International efforts are needed to reconsider why we are still unable to tackle this variation.

Effects of adenotonsillectomy on the growth of children with obstructive sleep apnoea-hypopnea syndrome (OSAHS): protocol for a systematic review.

INTRODUCTION: Obstructive sleep apnoea-hypopnea syndrome (OSAHS) is characterised by recurring episodes of complete or partial upper airway collapse during sleep. Persistent OSAHS is associated with long-term consequences, such as growth failure, cardiovascular and neurocognitive problems in children. Different from the aetiology of OSAHS in adults, the most common cause of paediatric OSAHS is adenotonsillar hypertrophy. Adenotonsillectomy (AT) has been recommended as the first-line treatment of paediatric OSAHS. Several studies have suggested that retarded growth caused by OSAHS can improve after AT during the prepubertal period. This review will systematically search and summarise the available evidence on the effects of AT on children's growth. METHODS AND ANALYSIS: We will conduct electronic searches in MEDLINE (via PubMed), Embase, Google Scholar and the Cochrane Central Register of Controlled Trials for randomised controlled trials (RCTs) or cohort studies that included a control group. Additional records will be searched by checking the references included in the selected studies and relevant reviews. At least two authors will undertake selection of studies and data extraction independently and in duplicate. The Cochrane Risk of Bias tool and Risk Of Bias In Non-randomised Studies-of Interventions will be used to assess the risk of bias of RCT and cohort studies, respectively. A random-effects model will be used for meta-analyses. Data synthesis and other analyses will be carried out using the RevMan V.5.3 software. The Grades of Recommendation, Assessment, Development and Evaluation will be used to assess the quality of the supporting evidence behind each main comparison. ETHICS AND DISSEMINATION: There is no ethical issue in this systematic review given that we will only include published studies. The results will be disseminated via peer-reviewed publications and social networks. PROSPERO REGISTRATION NUMBER: CRD42019125882.

The development of an opioid sparing anesthesia protocol for pediatric ambulatory tonsillectomy and adenotonsillectomy surgery-A quality improvement project.

Pain management following pediatric tonsillectomy and adenotonsillectomy surgery is challenging and traditionally involves perioperative opioids. However, the recent national opioid shortage compelled anesthesiologists at Bellevue Surgery Center to identify an alternative perioperative analgesic regimen that minimizes opioids yet provides effective pain relief. We assembled an interdisciplinary quality improvement team to trial a series of analgesic protocols using the Plan-Do-Study-Act cycle. Initially, we replaced intraoperative morphine and acetaminophen (M/A protocol) with intraoperative dexmedetomidine and preoperative ibuprofen (D/I protocol). However, when results were not favorable, we rapidly transitioned to intraoperative ketorolac and dexmedetomidine (D/K protocol). The following measures were evaluated using statistical process control chart methodology and interpreted using Shewhart's theory of variation: maximum pain score in the postanesthesia care unit, postoperative morphine rescue rate, postanesthesia care unit length of stay, total anesthesia time, postoperative nausea and vomiting rescue rate, and reoperation rate within 30 days of surgery. There were 333 patients in the M/A protocol, 211 patients in the D/I protocol, and 196 patients in the D/K protocol. With the D/I protocol, there were small increases in maximum pain score and postanesthesia care unit length of stay, but no difference in morphine rescue rate or total anesthesia time compared to the M/A protocol. With the D/K protocol, postoperative pain control and postanesthesia care unit length of stay were similar compared to the M/A protocol. Both the D/I and D/K protocols had reduced nausea and vomiting rescue rates. Reoperation rates were similar between groups. In summary, we identified an intraoperative anesthesia protocol for pediatric tonsillectomy and adenotonsillectomy surgery utilizing dexmedetomidine and ketorolac that provides effective analgesia without increasing recovery times or reoperation rates.

Clinical Practice Guideline: Tonsillectomy in Children (Update)-Executive Summary.

OBJECTIVE: This update of a 2011 guideline developed by the American Academy of Otolaryngology-Head and Neck Surgery Foundation provides evidence-based recommendations on the pre-, intra-, and postoperative care and management of children 1 to 18 years of age under consideration for tonsillectomy. Tonsillectomy is defined as a surgical procedure performed with or without adenoidectomy that completely removes the tonsil, including its capsule, by dissecting the peritonsillar space between the tonsil capsule and the muscular wall. Tonsillectomy is one of the most common surgical procedures in the United States, with 289,000 ambulatory procedures performed annually in children <15 years of age, based on the most recent published data. This guideline is intended for all clinicians in any setting who interact with children who may be candidates for tonsillectomy. PURPOSE: The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing children under consideration for tonsillectomy and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to educate clinicians, patients, and/or caregivers regarding the indications for tonsillectomy and the natural history of recurrent throat infections. Additional goals include the following: optimizing the perioperative management of children undergoing tonsillectomy, emphasizing the need for evaluation and intervention in special populations, improving the counseling and education of families who are considering tonsillectomy for their children, highlighting the management options for patients with modifying factors, and reducing inappropriate or unnecessary variations in care. Children aged 1 to 18 years under consideration for tonsillectomy are the target patient for the guideline. For this guideline update, the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of nursing, anesthesiology, consumers, family medicine, infectious disease, otolaryngology-head and neck surgery, pediatrics, and sleep medicine. KEY ACTION STATEMENTS: The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should recommend watchful waiting for recurrent throat infection if there have been <7 episodes in the past year, <5 episodes per year in the past 2 years, or <3 episodes per year in the past 3 years. (2) Clinicians should administer a single intraoperative dose of intravenous dexamethasone to children undergoing tonsillectomy. (3) Clinicians should recommend ibuprofen, acetaminophen, or both for pain control after tonsillectomy. The guideline update group made recommendations for the following KASs: (1) Clinicians should assess the child with recurrent throat infection who does not meet criteria in KAS 2 for modifying factors that may nonetheless favor tonsillectomy, which may include but are not limited to multiple antibiotic allergies/intolerance, PFAPA (periodic fever, aphthous stomatitis, pharyngitis, and adenitis), or history of >1 peritonsillar abscess. (2) Clinicians should ask caregivers of children with obstructive sleep-disordered breathing and tonsillar hypertrophy about comorbid conditions that may improve after tonsillectomy, including growth retardation, poor school performance, enuresis, asthma, and behavioral problems. (3) Before performing tonsillectomy, the clinician should refer children with obstructive sleep-disordered breathing for polysomnography if they are <2 years of age or if they exhibit any of the following: obesity, Down syndrome, craniofacial abnormalities, neuromuscular disorders, sickle cell disease, or mucopolysaccharidoses. (4) The clinician should advocate for polysomnography prior to tonsillectomy for obstructive sleep-disordered breathing in children without any of the comorbidities listed in KAS 5 for whom the need for tonsillectomy is uncertain or when there is discordance between the physical examination and the reported severity of obstructive sleep-disordered breathing. (5) Clinicians should recommend tonsillectomy for children with obstructive sleep apnea documented by overnight polysomnography. (6) Clinicians should counsel patients and caregivers and explain that obstructive sleep-disordered breathing may persist or recur after tonsillectomy and may require further management. (7) The clinician should counsel patients and caregivers regarding the importance of managing posttonsillectomy pain as part of the perioperative education process and should reinforce this counseling at the time of surgery with reminders about the need to anticipate, reassess, and adequately treat pain after surgery. (8) Clinicians should arrange for overnight, inpatient monitoring of children after tonsillectomy if they are <3 years old or have severe obstructive sleep apnea (apnea-hypopnea index ≥10 obstructive events/hour, oxygen saturation nadir <80%, or both). (9) Clinicians should follow up with patients and/or caregivers after tonsillectomy and document in the medical record the presence or absence of bleeding within 24 hours of surgery (primary bleeding) and bleeding occurring later than 24 hours after surgery (secondary bleeding). (10) Clinicians should determine their rate of primary and secondary posttonsillectomy bleeding at least annually. The guideline update group made a strong recommendation against 2 actions: (1) Clinicians should not administer or prescribe perioperative antibiotics to children undergoing tonsillectomy. (2) Clinicians must not administer or prescribe codeine, or any medication containing codeine, after tonsillectomy in children younger than 12 years. The policy level for the recommendation about documenting recurrent throat infection was an option: (1) Clinicians may recommend tonsillectomy for recurrent throat infection with a frequency of at least 7 episodes in the past year, at least 5 episodes per year for 2 years, or at least 3 episodes per year for 3 years with documentation in the medical record for each episode of sore throat and ≥1 of the following: temperature >38.3°C (101°F), cervical adenopathy, tonsillar exudate, or positive test for group A beta-hemolytic streptococcus. DIFFERENCES FROM PRIOR GUIDELINE: Incorporating new evidence profiles to include the role of patient preferences, confidence in the evidence, differences of opinion, quality improvement opportunities, and any exclusion to which the action statement does not apply. There were 1 new clinical practice guideline, 26 new systematic reviews, and 13 new randomized controlled trials included in the current guideline update. Inclusion of 2 consumer advocates on the guideline update group. Changes to 5 KASs from the original guideline: KAS 1 (Watchful waiting for recurrent throat infection), KAS 3 (Tonsillectomy for recurrent infection with modifying factors), KAS 4 (Tonsillectomy for obstructive sleep-disordered breathing), KAS 9 (Perioperative pain counseling), and KAS 10 (Perioperative antibiotics). Seven new KASs: KAS 5 (Indications for polysomnography), KAS 6 (Additional recommendations for polysomnography), KAS 7 (Tonsillectomy for obstructive sleep apnea), KAS 12 (Inpatient monitoring for children after tonsillectomy), KAS 13 (Postoperative ibuprofen and acetaminophen), KAS 14 (Postoperative codeine), and KAS 15a (Outcome assessment for bleeding). Addition of an algorithm outlining KASs. Enhanced emphasis on patient and/or caregiver education and shared decision making.

Why Is There No Statement Regarding Partial Intracapsular Tonsillectomy (Tonsillotomy) in the New Guidelines?

Partial intracapsular tonsillectomy (PIT) was revisited in 2003 as an alternate surgical option to total tonsillectomy for the treatment of tonsillar hypertrophy. However, evaluation of the existing literature on PIT reveals that it is largely focused on comparing perioperative outcomes after PIT and total tonsillectomy, with few data regarding long-term outcomes. The goal of this commentary is to explain why PIT was not incorporated into the 2019 American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline for tonsillectomy, while acknowledging its use and potential advantages and disadvantages and outlining future research opportunities.

Obstructive sleep disordered breathing in children - an important problem in the light of current European guidelines.

Obstructive sleep-disordered breathing (SDB) is a common clinical problem. An unrecognized and untreated SDB is a serious threat for an intensively developing organism of a child. The consequences of SDB include cardiovascular and neurological complications, growth disorders and enuresis. Therefore, SDB in children becomes an important subject of many scientific investigations, publications, and congresses. In 2015 the European Respiratory Society Task Force published a document concerning the conclusions about the diagnostics and treatment of SDB in children and youth from 2 to 18 years of age (Fig. 1). The scientific data from 362 publications were presented in a condensed form of "seven steps", very useful in diagnosing and treatment planning (1). The authors underline the limited number of reliable evidence about SDB: prospective studies, randomized double-blinded studies with placebo. The presented evidence was categorized depending on their quality according to the classification of the American Academy of Neurology (ANN) into classes I - IV. Previously, in 2012, the guidelines of the American Academy of Pediatrics on obstructive sleep apnea syndrome (OSAS) in children with tonsillar hypertrophy and/or obesity were published (2, 3) and they were a valuable diagnostic and therapeutic compendium. The European guidelines discussed in this article result from the progress of knowledge in recent years, they cover the subject broadly, consider rare and difficult cases and present the spectrum of potential therapeutic actions. The aim of the guidelines is a better recognition of SDB, a systematization of diagnosis and treatment at every stage of medical care, including the causes of this disorder and its complications.

An analysis of the literature addressing tonsillectomy knowledge gaps.

IMPORTANCE: The ability of clinical practice guidelines to improve patient outcomes depends on the quality of evidence that they are built upon. Research into tonsillectomy in children is lacking, and the gaps in evidence were identified by guideline authors. OBJECTIVE: The objective of this study is to evaluate the extent that new research is addressing the gaps identified in the AAO-HNS Tonsillectomy in Children Guideline. DESIGN: For each recommendation in the AAO-HNS guideline Tonsillectomy In Children, we created PICO (Participants, Intervention, Comparator, Outcome) questions and search strings. PubMed was searched to locate studies undertaken after the final literature search performed by the AAO-HNS work group. These studies were then extracted and analyzed. SETTING: This study is relevant to all invested in focusing otolaryngological research on questions which currently lack strong evidence. PARTICIPANTS: Trials in tonsillectomy that started after the development of the AAO-HNS clinical practice guidelines. MAIN OUTCOME MEASURES: The main outcome measures of this study is the extent to which tonsillectomy research is addressing the evidence gaps listed in the clinical practice guideline. RESULTS: Of the 2519 studies included in our sample, 276 (11%) were relevant to the 18 recommendations made within the Tonsillectomy in Pediatric Patients clinical practice guideline. All but one of the recommendations was met by at least one study. CONCLUSIONS: and Relevance: Our findings indicate that knowledge gaps within the guideline at publication may have since been addressed and a guideline update may thus be warranted. LEVEL OF EVIDENCE: NA.

Incidence of allergic rhinitis in children with residual snoring and sleep symptoms after adenotonsillectomy.

BACKGROUND AND OBJECTIVES: Allergic rhinitis may contribute to sleep disordered breathing (SDB) in children. Although adenotonsillectomy is commonly performed to treat SDB, some patients will return to their primary practitioners with residual sleep symptoms. The aim of this study was to assess the incidence of allergic rhinitis via radioallergosorbent testing (RAST) in children undergoing adenotonsillectomy who had residual snoring or sleep symptoms. METHOD: A retrospective analysis of 500 patients post-adenotonsillectomy was undertaken. The incidence of residual snoring, residual sleep symptoms and results of RAST, as well as total immunoglobulin E (IgE) after surgical intervention, were documented. RESULTS: Children with positive RAST results or elevated total IgE had a significantly greater incidence of residual snoring post-adenotonsillectomy (P = 0.049) and residual sleep symptoms after surgery (P <0.0001). DISCUSSION: A positive RAST or elevated IgE in children with SDB was associated with incomplete resolution of snoring and residual sleep symptoms after adenotonsillectomy. Thus, there should be raised suspicion of allergic rhinitis in this population.

Day case paediatric tonsillectomy: a quality improvement project.

Tonsillectomy is one of the commonest ENT paediatric procedures. Recovery is best achieved at home, and cost-effectiveness of the day case pathway is significant in tonsillectomy. This project scrutinised the local practice regarding the effectiveness of day case pathway in paediatric tonsillectomy in a large regional teaching hospital. The project aimed to improve the rates of day case tonsillectomy discharges, to increase compliance of postoperative care with guidelines, and to assess long-term sustainability of the new practice. The project looked prospectively at the pre-existing paediatric tonsillectomy day case practice (cycle 1) prior to implementing a multifaceted intervention. The intervention consisted of an evidence-based change to local day case tonsillectomy guidelines, improved lists' planning/management, and clinicians' education. Thereafter, the outcomes were measured in the short term (cycle 2-prospective data collection) and in the long term (cycle 3-retrospective data collection). The gathered data revealed an improvement in post-tonsillectomy day case discharge rates (both short and long term), without an increase in postoperative complications. Moreover, our intervention had effectively reduced sleep study requests and resulted in a significant increase in list profitability.Conclusion: The departmental practice in paediatric day case tonsillectomy was improved via evidence-based relaxation of day case criteria, improved list management, and clinicians' education. The interventions resulted also in a positive significant financial impact with no increase in postoperative complications. What is Known: • Tonsillectomy is a common paediatric ENT procedure, with significant applicability and cost-effectiveness of the day case pathway. • There is a lack of a clear general consensus on criteria for patients' suitability for day case tonsillectomy. What is New: • This quality improvement project carried out a methodical relaxation of day case criteria of day case tonsillectomy. • The new criteria along with enhanced list management and clinician education had safely improved the local post-tonsillectomy day case care.

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.

Reducing Readmissions Post-tonsillectomy: A Quality Improvement Study on Intravenous Hydration.

INTRODUCTION: Dehydration is a potentially preventable complication post-tonsillectomy and can result in an Emergency Department visit and/or readmission. Our objectives were to identify risk factors for dehydration readmissions and develop interventions to prevent them. METHODS: We used retrospective chart reviews to determine if increased intravenous (IV) hydration post-tonsillectomy prevented hospital readmissions for dehydration. All children aged 1-18 years who underwent tonsillectomy between July 1, 2007 and September 30, 2015 were included in this quality improvement study. Using the Pediatric Health Information System database, patients who experienced a readmission for dehydration within 72 hours of surgery were identified and validated with internal data. We analyzed the pre-implementation and post-implementation readmission rates after standardization of increased IV fluids (1.5 times maintenance). An interrupted time series analysis was used to estimate the effects of our hydration initiative. RESULTS: Of 11,157 patients who underwent tonsillectomy during the study period, 96 (0.9%) met the criteria for readmissions for dehydration. The pre-implementation readmission rate was 1% compared to 0.2% post-implementation, a reduction of 82%. CONCLUSIONS: The hydration initiative was associated with a significant decrease in hospital readmissions. This safe, low-cost, easy-to-implement approach to preventing dehydration post-tonsillectomy could be explored at other institutions.

Impact of a pediatric anesthesiologist on operating room efficiency during pediatric tonsillectomies and adenotonsillectomies.

We conducted a retrospective case review to determine if the presence of an Accreditation Council for Graduate Medical Education (ACGME) fellowship-trained pediatric anesthesiologist improves efficiency during pediatric tonsillectomies and adenotonsillectomies in hospitals that do not have dedicated pediatric operating rooms and, if so, to determine which specific anesthesia practices might account for such a difference. We reviewed the charts of all patients aged 12 years and younger who had undergone a tonsillectomy or adenotonsillectomy from Jan. 1, 2008, through Aug. 1, 2013, at San Francisco General Hospital. A total of 75 cases met our eligibility criteria. We compiled information on patient demographics, surgical time, anesthesia time, and anesthesia practices. Our primary study outcome was the amount of anesthesia-controlled time (ACT), which is the sum of time spent in induction and emergence. Cases were grouped according to whether the operation was staffed by an ACGME fellowship-trained pediatric anesthesiologist or a general anesthesiologist. Data were analyzed for 1 pediatric anesthesiologist and 23 general anesthesiologists. We found that ACT was significantly shorter during the cases staffed by the ACGME fellowship-trained pediatric anesthesiologist, although there were no major differences in anesthesia practices between the types of anesthesiologist. We suggest that staffing pediatric tonsillectomy operations with a fellowship-trained pediatric anesthesiologist may be an effective strategy for increasing operating room efficiency.
