Expert Consensus Statement: Management of Dysphagia in Head and Neck Cancer Patients.

To develop an expert consensus statement (ECS) on the management of dysphagia in head and neck cancer (HNC) patients to address controversies and offer opportunities for quality improvement. Dysphagia in HNC was defined as swallowing impairment in patients with cancers of the nasal cavity, paranasal sinuses, nasopharynx, oral cavity, oropharynx, larynx, or hypopharynx. Development group members with expertise in dysphagia followed established guidelines for developing ECS. A professional search strategist systematically reviewed the literature, and the best available evidence was used to compose consensus statements targeted at providers managing dysphagia in adult HNC populations. The development group prioritized topics where there was significant practice variation and topics that would improve the quality of HNC patient care if consensus were possible. The development group identified 60 candidate consensus statements, based on 75 initial proposed topics and questions, that focused on addressing the following high yield topics: (1) risk factors, (2) screening, (3) evaluation, (4) prevention, (5) interventions, and (6) surveillance. After 2 iterations of the Delphi survey and the removal of duplicative statements, 48 statements met the standardized definition for consensus; 12 statements were designated as no consensus. Expert consensus was achieved for 48 statements pertaining to risk factors, screening, evaluation, prevention, intervention, and surveillance for dysphagia in HNC patients. Clinicians can use these statements to improve quality of care, inform policy and protocols, and appreciate areas where there is no consensus. Future research, ideally randomized controlled trials, is warranted to address additional controversies related to dysphagia in HNC patients.

Blood culture collection practices in NICU; A national survey.

Sepsis is the leading cause of mortality and morbidity in neonates. Blood cultures are the gold standard in diagnosing neonatal sepsis; however, there are currently no consensus guidelines for blood culture collection in neonates and significant practice variation exists in Neonatal Intensive Care Units (NICUs) globally. To examine current practices in obtaining blood cultures in the evaluation of neonatal sepsis in NICUs across Canada. A nine-item electronic survey was sent to each of the 29 level-3 NICUs in Canada, which are equipped to provide highly specialized care for newborns. Responses were received from 90% (26/29) of sites. Sixty-five percent (17/26) of sites have blood culture collection guidelines for the investigation of neonatal sepsis. Forty-eight percent (12/25) of sites routinely target 1.0 mL per culture bottle. In late-onset sepsis (LOS), 58% (15/26) of sites process one aerobic culture bottle, whereas four sites routinely add anaerobic culture bottles. In early-onset sepsis (EOS) in very low birth weight infants (BW <1.5 kg), 73% (19/26) of sites use umbilical cord blood, and 72% (18/25) use peripheral venipuncture. Two sites routinely collect cord blood for culture in EOS. Only one site applies the concept of differential time-to-positivity to diagnose central-line-associated bloodstream infection. There is significant practice variation in methods used to obtain blood cultures in level-3 NICUs across Canada. Standardization of blood culture collection practices can provide reliable estimates of the true incidence of neonatal sepsis and help to develop appropriate antimicrobial stewardship strategies.

A94 EXPLORING THE SOCIOECONOMIC BURDEN OF PEDIATRIC INFLAMMATORY BOWEL DISEASE: A SURVEY OF FAMILIES AND PEDIATRIC PROVIDERS

Abstract Background Rates of pediatric inflammatory bowel disease (IBD) have been increasing significantly over recent decades, contributing to the rising chronic disease burden across pediatrics. Currently, there is very limited literature exploring the financial burden on families of children with IBD. In fact, there is only one Canadian study in this area despite Canada having one of the highest rates of pediatric IBD in the world. Purpose The goal of this study is to better understand the socioeconomic burden of pediatric IBD at our institution and compare institutional practices across the country. Method The study took place at a large, tertiary care pediatric centre in Edmonton, Alberta, Canada between October 2022 and January 2023. Two separate electronic surveys were developed and distributed to all families of children with IBD at our institution (N= ~400) and pediatric IBD providers across the country (N= ~45) respectively. Surveys explored demographic information, financial impacts of IBD diagnosis and perceptions around pediatric IBD care and financial support. Result(s) Interim results (N=3) indicate dietary therapy costs, missed time off work and school and time off for IBD treatment as considerable burdens on families. Across the country, initial provider data (N=6) suggests significant variability in clinical practice, allied health support and financial support for families. There is overwhelming agreement among providers that the socioeconomic burdens on families is significant. Further data and regression analysis is ongoing. Conclusion(s) This is the first study in Canada to directly explore the socioeconomic burden on families of children with IBD. Results indicate good correlation between provider awareness and the increased financial burden on families but also considerable variation in practice across the country. Data suggest further research and advocacy is required to better support patients, however various quality improvement opportunities exist both locally and beyond.

Current Practice Patterns in the Surgical Management of Benign Prostatic Hyperplasia

ObjectiveTo use American Board of Urology (ABU) case log data to elucidate practice patterns for benign prostatic hyperplasia (BPH) surgery. Several surgical modalities have been introduced in recent decades causing significant practice variation. Materials and MethodsWe retrospectively analyzed ABU case logs from 2008-2021 to assess trends in BPH surgery. We created logistic regression models to identify surgeon-sided factors associated with utilization of each surgical modality. ResultsWe identified 6,632 urologists who logged 73,884 surgeries for BPH. Transurethral resection of the prostate (TURP) was the most commonly performed BPH surgery in all but 1 year, and odds of performing a TURP increased year-over-year (OR 1.055, 95% CI [1.013,1.098], P = .010). The use of holmium laser enucleation of the prostate (HoLEP) did not change over time. HoLEP was more likely to be performed by urologists with higher BPH surgical volume (OR 1.017, CI [1.013, 1.021], P < .001) and with endourology subspecialization (OR 2.410, CI [1.45, 4.01], P = .001). Prostatic urethral lift (PUL) utilization increased significantly since its introduction in 2015 (OR 1.663, CI [1.540, 1.796], P < .001). PUL currently comprises over one third of all BPH surgeries logged. ConclusionIn the face of newer technologies, TURP remains the most common surgery for BPH in the United States. PUL has been rapidly adopted while HoLEP comprises a consistent minority of cases. Surgeon age, patient age, and urologist subspecialization were associated with use of certain BPH surgical approaches.

A National Survey Assessing the Variability in the Management of Traumatic Cardiac Arrest.

Resuscitation of traumatic cardiac arrest (TCA) is variable, with approaches that overlap Advanced Trauma Life Support (ATLS) and Advanced Cardiac Life Support (ACLS) algorithms. There is no standard algorithm for TCA, with some withholding ACLS protocols given abysmal outcomes. This study aims to assess surgeon practices and attitudes toward resuscitation practices in TCA. A 16-question web-based survey was distributed to the membership of a national trauma association. Respondent demographics and management of TCA were analyzed. Chi-squared tests determined statistical significance. Open-ended responses were coded and analyzed inductively. Two hundred and three surveys were completed. 73.4% of respondents reported utilizing ACLS, while 26.6% reported they never utilized ACLS. A statistically significant difference in the performance of ACLS was found based on number of years in practice (P = .025) and the state of practice (P = .006). There was no significant difference in self-reported survival rates or legal, ethical, or interpersonal conflicts. Qualitative data highlighted themes of interpersonal conflict and futility. This study shows that one-quarter of respondents never utilize ACLS in TCA. Of those that utilize ACLS, there was variability in the technique, indication, and duration of resuscitation. Despite significant variability in technique, there appears to be similar survival rates and incidence of conflict. The association between years in practice and ACLS use suggests this may represent an emerging change in practice. The low response rate limits generalizability; however, there is significant variability in practice, highlighting a need for evidence-based guidelines.

Management practices in hospitals: A public-private comparison.

We use information on management practices in 1,183 hospitals in 7 different countries, collected in 2010 within the "World Management Survey" initiative, to estimate the role of public ownership on different management dimensions, such as monitoring performance, setting targets and incentivizing employees. A significant variation in management practices both between countries and, within countries, across hospitals is found. We show that managers in public sector hospitals tend to underperform, relative to private hospitals, in all the countries considered. Larger hospitals appear to be better managed, while there is no difference between teaching and other type of hospitals. Publicly owned hospitals appear less efficient in the provision of incentive schemes to promote and reward highly motivated employees, or remove poor performers. Overall, public ownership is associated with a reduction of about 10% in management score, which corresponds approximately to a half-standard deviation.

Hospital variability in adoption of alcohol and drug screening in adult trauma patients.

Despite recommendations to screen all injured patients for substance use, single-center studies have reported underscreening. This study sought to determine if there was significant practice variability in adoption of alcohol and drug screening of injured patients among hospitals participating in the Trauma Quality Improvement Program. This was a retrospective observational cross-sectional study of trauma patients 18 years or older in Trauma Quality Improvement Program 2017-2018. Hierarchical multivariable logistic regression modeled the odds of screening for alcohol and drugs via blood/urine test while controlling for patient and hospital variables. We identified statistically significant high and low-screening hospitals based on hospitals' estimated random intercepts and associated confidence intervals (CIs). Of 1,282,111 patients at 744 hospitals, 619,423 (48.3%) were screened for alcohol, and 388,732 (30.3%) were screened for drugs. Hospital-level alcohol screening rates ranged from 0.8% to 99.7%, with a mean rate of 42.4% (SD, 25.1%). Hospital-level drug screening rates ranged from 0.2% to 99.9% (mean, 27.1%; SD, 20.2%). A total of 37.1% (95% CI, 34.7-39.6%) of variance in alcohol screening and 31.5% (95% CI, 29.2-33.9%) of variance in drug screening were at the hospital level. Level I/II trauma centers had higher adjusted odds of alcohol screening (adjusted odds ratio [aOR], 1.31; 95% CI, 1.22-1.41) and drug screening (aOR, 1.16; 95% CI, 1.08-1.25) than Level III and nontrauma centers. We found 297 low-screening and 307 high-screening hospitals in alcohol after adjusting for patient and hospital variables. There were 298 low-screening and 298 high-screening hospitals for drugs. Overall rates of recommended alcohol and drug screening of injured patients were low and varied significantly between hospitals. These results underscore an important opportunity to improve the care of injured patients and reduce rates of substance use and trauma recidivism. Prognostic and Epidemiological; Level III.

The management of developmental dysplasia of the hip in children aged under three months : a consensus study from the British Society for Children's Orthopaedic Surgery.

A national screening programme has existed in the UK for the diagnosis of developmental dysplasia of the hip (DDH) since 1969. However, every aspect of screening and treatment remains controversial. Screening programmes throughout the world vary enormously, and in the UK there is significant variation in screening practice and treatment pathways. We report the results of an attempt by the British Society for Children's Orthopaedic Surgery (BSCOS) to identify a nationwide consensus for the management of DDH in order to unify treatment and suggest an approach for screening. A Delphi consensus study was performed among the membership of BSCOS. Statements were generated by a steering group regarding aspects of the management of DDH in children aged under three months, namely screening and surveillance (15 questions), the technique of ultrasound scanning (eight questions), the initiation of treatment (19 questions), care during treatment with a splint (ten questions), and on quality, governance, and research (eight questions). A two-round Delphi process was used and a consensus document was produced at the final meeting of the steering group. A total of 60 statements were graded by 128 clinicians in the first round and 132 in the second round. Consensus was reached on 30 out of 60 statements in the first round and an additional 12 in the seond. This was summarized in a consensus statement and distilled into a flowchart to guide clinical practice. We identified agreement in an area of medicine that has a long history of controversy and varied practice. None of the areas of consensus are based on high-quality evidence. This document is thus a framework to guide clinical practice and on which high-quality clinical trials can be developed.Cite this article: Bone Joint J2023;105-B(2):209-214.

1234 IMPROVING HEART FAILURE MANAGEMENT WITHIN HOSPITAL AT HOME

Abstract Introduction Heart failure (HF) is a common problem managed in our West Lothian multi-disciplinary hospital at home (HaH) service, however significant variation in practice was noted with considerable resource implications. We aimed to standardise and improve this by developing a dedicated protocol. Methods We developed a protocol to guide the assessment and management of HF within HaH. We collected baseline (n=25) and follow-up data (n=10) after protocol introduction from patients referred to HaH with heart failure. Outcomes reviewed included anticipatory care planning (ACP) decisions, length of stay (LOS) and treatment strategy. We held staff education sessions and surveyed staff confidence regarding HF management. Results ACP discussion rates improved after protocol introduction, with decision rates improving for both escalation of care (28% to 80%) and resuscitation (44% to 60%). LOS reduced after protocol introduction (mean 6.3 days to 5.9 days). Titration of oral diuretics alone (71%) was associated with a shorter LOS (mean 5.4 days) compared to IV (29%, mean 8.1 days), with no difference in 28 day outcome. In those with HF with reduced ejection fraction, the rates of beta-blocker prescription increased (57% to 80%) however ACE-inhibitor prescription decreased (29% to 20%). Use of add-on therapy (e.g. thiazide diuretics) increased (12% to 30%) with a decrease in complication rates (12% to 0%). All staff found the protocol helpful with an improvement in confidence levels. Conclusions Through introducing a standardised protocol, we observed an improvement in anticipatory care discussion rates and a trend towards shorter LOS. Oral diuretic titration was less resource intensive without an adverse impact on outcome. Future plans include ongoing education and data collection, trialling a joint multi-disciplinary meeting with cardiology for discussion of complex patients and embedding a treatment strategy of oral diuretic titration with a ‘discharge with planned review' approach in appropriate patients.

The timing of drain removal in parotidectomies: outcomes of removal at 4 h post-operatively and a Canadian survey of practice patterns

BackgroundThe post-operative management of parotidectomies is highly provider dependent. No guidelines are currently available for timing of parotid drain removal. This study aimed to assess: (1) outcomes and complications after early drain removal (< 4 h, post-operative day [POD] 0) versus late drain removal (POD ≥ 1); (2) current Canadian provider practices.MethodsA single surgeons ten-year parotidectomy practice was reviewed, spanning his practice change from routine POD ≥ 1 drain removal to POD 0 removal, with extraction of patient demographic, disease, and complication variables. An anonymous, cross-sectional survey on parotid drain practices was distributed to Canadian Society of Otolaryngology-Head and Neck Surgery members. Descriptive statistics, Wilcoxon Rank Sum, and unpaired student’s t-tests were calculated.ResultsIn total, 526 patients were included and 44.7% (235/526) had drains removed POD 0. There was no significant difference in hematoma or seroma rates between the POD 0 and POD ≥ 1 drain removal cohorts. The national survey on parotid drain management had 176 responses. The majority (67.9%) reported routinely using drains after parotidectomy and 62.8% reported using a drain output based criteria for removal. The most common cut-off output was 30 ml in 24 h (range 5–70 ml).ConclusionThere was no difference in hematoma or seroma rates for patients with parotid drains removed on POD 0 versus POD ≥ 1. Our national survey found significant variation in Canadian parotidectomy drain removal practices, which may be an area that can be further assessed to minimize hospital resources and improve patient care.Graphic abstract

The DEFINITE Audit: a prospective audit of diabetic foot debridement in theatre – a protocol

Background: People with diabetes are commonly affected by foot ulceration (DFU) and subsequent or concurrent infection (DFI). Surgical debridement is often needed to contain infection. Despite international guidelines, there remains significant variation in surgical practice of diabetic foot wound debridement in the operating theatre. Methods: Diabetic Foot Ulcer Debridement in Theatre Audit (DEFINITE) is a global multicentre, prospective audit of consecutive patients undergoing a debridement or minor amputation in theatre for a diabetic foot complication. DEFINITE is led by the Vascular and Endovascular Research Network (VERN). The primary outcome is adherence to recommended practice as outlined in the International Working Group on the Diabetic Foot and Global Vascular Guidelines. Secondary outcomes are incidence of healing, re-admission, further amputation (minor and major) and mortality at 90 days. Anonymised data will be collected via REDCap. Eligibility and study registration at all hospital institutions performing in-theatre management of diabetic foot complications are eligible to participate after obtaining appropriate institutional level audit approvals. A lead clinician will be responsible for approvals and data management. Pathway to impact: This audit addresses shared patient-clinician priorities and is supported by the UK Vascular Society multidisciplinary Special Interest Group on the Diabetic Foot. The results will be presented at international scientific meetings and submitted for publication in peer-reviewed publications. The results will also be used to initiate improvement in patient care.

Natural Cycle Frozen Embryo Transfer: Evaluating Optimal Protocols for Preparation and Timing.

While natural cycle frozen embryo transfer (NC-FET) is becoming increasingly common, significant practice variation exists in the use of ovulation induction medications, administration of ovulation trigger, and timing of embryo transfer without consensus as to the optimal protocol. The objective of this study is to evaluate the association of key aspects of the NC-FET protocol with implantation, pregnancy and live birth. This was a retrospective cohort study of blastocyst stage NC-FET cycles from October 2019 to July 2021 at a single academic fertility centre. Protocols varied between cycles across three key parameters which were evaluated as primary predictors of cycle outcomes: (1) use of letrozole for mild ovarian stimulation/ovulation induction, (2) administration of exogenous ovulation trigger versus spontaneous luteinising hormone surge and (3) transfer timing based on ovulation trigger versus sequential progesterone monitoring. Primary outcomes included implantation rate, clinical pregnancy and ongoing pregnancy. Generalised estimating equations were fitted to obtain adjusted odds ratios or rate ratios as appropriate with 95% confidence intervals for each outcome across the three primary predictors. A total of 183 cycles from 170 unique patients were eligible for inclusion. The average implantation rate was 0.58, resulting in an overall clinical pregnancy and ongoing pregnancy rate of 59.0% and 51.4%, respectively. After adjusting for age at embryo freeze and history of a failed embryo transfer, there were no significant associations between any predictor and implantation rate, clinical pregnancy, ongoing pregnancy, or live birth. In NC-FET, a variety of preparation and timing protocols may lead to comparable cycle outcomes, potentially allowing for flexibility on the basis of patient and physician preference. These findings warrant validation in a larger, randomised trial.

Nd:YAG Laser Capsulotomy Rates in the Netherlands; Practice Variation and Association with Physician Practice Styles.

To determine the practice variation in rate of Nd:YAG laser capsulotomy within one year after cataract surgery and to identify possible associations with physician practice styles. All hospitals and private clinics in The Netherlands. Retrospective observational study. In the national medical claims database, we identified all laser capsulotomies performed in the Netherlands within a year after cataract surgery in the years 2016 and 2017. Centres with the lowest and highest percentages of Nd:YAG laser capsulotomies were interviewed on their physician practice styles related to the development of posterior capsule opacification. The incidence of Nd:YAG laser capsulotomy varied between 1.2% and 26.0% in 2016 (median 5.0%) and between 0.9% and 22.7% in 2017 (median 5.0%). The rate of capsulotomy was highly consistent over time for each centre (Pearson correlation coefficient, 0.89, P < 0.001). In general, ophthalmology centres with a high rate of Nd:YAG laser capsulotomy more often did not (routinely) polish the posterior lens capsule, performed cortex removal with coaxial irrigation/aspiration (instead of bimanual), and more often used hydrophilic IOLs (compared to only using hydrophobic IOLs). We found a significant practice variation in performing Nd:YAG laser capsulotomy within one year after cataract surgery in the Netherlands. Routinely polishing the posterior capsule, using bimanual I/A, and the use of hydrophobic IOLs are associated with a lower incidence in Nd:YAG laser capsulotomy. Incorporating these practice styles may lower the practice variation and thus prevent added medical burden for the patient and decrease costs.

Developing Cardiothoracic Surgical Critical Care Intensivists: A Case for Distinct Training.

Cardiothoracic surgical critical care medicine is practiced by a diverse group of physicians including surgeons, anesthesiologists, pulmonologists, and cardiologists. With a wide array of specialties involved, the training of cardiothoracic surgical intensivists lacks standardization, creating significant variation in practice. Additionally, it results in siloed physicians who are less likely to collaborate and advocate for the cardiothoracic surgical critical care subspeciality. Moreover, the current model creates credentialing dilemmas, as experienced by some cardiothoracic surgeons. Through the lens of critical care anesthesiologists, this article addresses the shortcomings of the contemporary cardiothoracic surgical intensivist training standards. First, we describe the present state of practice, summarize past initiatives concerning specific training, outline why standardized education is needed, provide goals of such training standardization, and offer a list of desirable competencies that a trainee should develop to become a successful cardiothoracic surgical intensivist.

Recommendation to update the British Society for Cutaneous Allergy corticosteroid series.

Patch testing is an important investigation when dermatitis is unresponsive to, or worsened by, topical corticosteroid treatment. There is a balance to be struck between testing too many allergens, which is expensive, time consuming and risks causing sensitization, and testing too few, which risks missing the diagnosis. The current British Society for Cutaneous Allergy (BSCA) corticosteroid series comprises eight allergens and was last updated in February 2007. To review and update the BSCA corticosteroid series. We retrospectively analysed data from 16 patch test centres in the UK and Ireland for all patients who were patch tested to a corticosteroid series between August 2017 and July 2019. We recorded the allergens tested, the number and percentage tested to a corticosteroid series and the number of positive results for each allergen. We identified the allergens that test positive in ≥ 0.1% of selectively tested patients. Overall, 3531 patients were tested to a corticosteroid series in the 16 centres. The number of allergens tested ranged from 7 to 18 (mean 10). The proportion of patch test patients who were tested to a corticosteroid series ranged from 1% to 99%. Six allergens in the 2017 BSCA series tested positive in ≥ 0.1% of patients. Nine allergens not in the BSCA corticosteroid series tested positive in ≥ 0.1% of patients. This audit demonstrates the importance of regular review of recommended series and the significant variations in practice. The new BSCA corticosteroid series that we recommend contains 13 haptens, with the addition of the patient's own steroid creams as appropriate.

HPB P27 Stereotactic Ablative Radiotherapy in Colorectal Liver Metastases: A Systematic Review and Descriptive Summary of Practice

Abstract Background Treatment options for unresectable Colorectal Liver Metastases (CRLM) have, until recently, been mostly limited to radiofrequency or microwave ablation though there are some limitations. Stereotactic Ablative Radiotherapy (SABR) is being used increasingly to overcome these limitations with control rates and survival outcomes, reported to be comparable to ablation. However, there are several unknown factors regarding the use of SABR in CRLM, including the criteria for patient selection, optimal dose delivery and target volumes. This systematic review aims to summarise and describe the patient selection, indications, treatment regimens and survival outcomes for SABR in CRLM. Methods The literature was searched systematically to identify all articles reporting on SABR for CRLM, from inception until 1st January 2021. Primary research studies were included if they described the patient inclusion criteria, treatment regimens and outcomes from inoperable CRLM. Studies with extra-hepatic colorectal metastases were included if the metastases were deemed treatable with local therapies. Recommendations from the UK SABR consortium was used to categorise radiation dosage and fractionation. Data were collected on patient demographics, selection criteria, radiotherapy delivery and dosage and survival outcomes. Results Fifteen studies were included with a total of 522 patients and 770 liver metastases. Most studies (9/15) included patients with three or fewer metastases, however the tumour size varied from 4–15cm. Eleven studies stipulated that CRLM must be unresectable, with only one study defining unresectability according to patient or disease characteristics. Three quoted inoperability after multidisciplinary or tumour board decision, the remainder did not justify inoperability. Of these eleven, six studies stipulated that they must also be unsuitable for ablation. Patients with extra-hepatic metastases were included in ten studies, but the justification was inconsistent across all studies. Total radiation dose and fractionation varied across all studies, ranging from 16–75Gy and 3–8 fractions respectively. No studies pre-determined a target dosage for any cohort. Approximately half (149/301) of all patients received regimens in accordance with the UK SABR Consortium recommendations. Immobilisation methods were reported in eleven studies with nine different permutations including moulds, frames, abdominal compressions or breath control techniques. One year local control was reported at 48–96%, 2 years: 36–91% and 3 years: 26–85%. Overall survival at 1 year ranged from 53–100%, 2 years: 26–81% and 3 years: 21–65%. Conclusions There are significant variations in practice for delivering SABR for CRLM. There is no absolute consensus determining patient selection or treatment regimens. Although outcomes may seem promising in a selection of studies, the wide range of results and heterogeneity of studies means that truly reliable conclusions cannot be synthesised. Consensus statements to inform high-quality prospective studies are urgently needed to optimise treatment and improve patient outcomes.

Regional Differences in Procedural Care of Hemorrhoid Management in Medicare Patients; Unwarranted Variation in Clinical Practice for a Medical-First Problem

IntroductionHemorrhoid disease is very common problem in the Medicare population. Prior work has shown significant variation in county-level practices of hemorrhoidectomy; however, regional variation of rubber band ligation (RBL) has yet to be assessed. This is important as many different practitioners from different specialties can perform this procedure repeatedly in an office-based setting. We aim to evaluate the variation of RBL and hemorrhoidectomy over a 7-y period. MethodsUsing Medicare part B claims data, we identified all beneficiaries >65 y seen for hemorrhoid disease between 2006 and 2013. Current Procedural Terminology (CPT) codes were used to identify all events for hemorrhoidectomy (46083, 46250, 46255, 46257, 46260, and 46261) or RBL (46221) by hospital referral region (HRR). We determined HRR-level rates of hemorrhoidectomy and RBL per 1000 beneficiaries adjusted for age, sex, and race. We calculated annual coefficients of variation (SD × 100/mean) for hemorrhoidectomy and RBL. Results1.2 to 1.3 million fee-for-service Medicare beneficiaries were seen annually for evaluation of hemorrhoid disease. Mean-adjusted annual rates for hemorrhoidectomy by HRRs varied from 4.34 to 63.03 per 1000 beneficiaries. Mean-adjusted rates of RBL by HRRs varied from 7.06 to 163 per 1000 beneficiaries. Annual procedural coefficients of variation over the study period were 41-48 (high) for hemorrhoidectomy and 69-74 (very high) for RBL. ConclusionsWhile continued high variation exists for hemorrhoidectomy, there is very high variation for RBL between HRRs in treating hemorrhoid disease among Medicare beneficiaries. There are substantial Medicare expenditures in this high-volume population that are likely unwarranted.

Management of routine postoperative pain for children undergoing cardiac surgery: a Paediatric Acute Care Cardiology Collaborative Clinical Practice Guideline.

Pain following surgery for cardiac disease is ubiquitous, and optimal management is important. Despite this, there is large practice variation. To address this, the Paediatric Acute Care Cardiology Collaborative undertook the effort to create this clinical practice guideline. A panel of experts consisting of paediatric cardiologists, advanced practice practitioners, pharmacists, a paediatric cardiothoracic surgeon, and a paediatric cardiac anaesthesiologist was convened. The literature was searched for relevant articles and Collaborative sites submitted centre-specific protocols for postoperative pain management. Using the modified Delphi technique, recommendations were generated and put through iterative Delphi rounds to achieve consensus. 60 recommendations achieved consensus and are included in this guideline. They address guideline use, pain assessment, general considerations, preoperative considerations, intraoperative considerations, regional anaesthesia, opioids, opioid-sparing, non-opioid medications, non-pharmaceutical pain management, and discharge considerations. Postoperative pain among children following cardiac surgery is currently an area of significant practice variability despite a large body of literature and the presence of centre-specific protocols. Central to the recommendations included in this guideline is the concept that ideal pain management begins with preoperative counselling and continues through to patient discharge. Overall, the quality of evidence supporting recommendations is low. There is ongoing need for research in this area, particularly in paediatric populations.

Red Blood Cell Utilization Among Patients with Sickle Cell Disease: A Single Center Experience

Introduction: Red blood cell (RBC) transfusion remains a mainstay of treatment for both acute and chronic complications of sickle cell disease (SCD). RBC transfusions improve oxygen-carrying capacity of blood, decrease hemoglobin S levels, and are indicated for the treatment of complications such as stroke, acute chest syndrome, sickle cell hepatopathy and multiorgan failure syndrome. RBC transfusions may also be considered to reduce the frequency of pain crises for those intolerant or non-responsive to hydroxyurea. Prior practice surveys havedemonstrated significant practice variation in the management of patients with SCD with respect to RBC transfusions. The utilization of both simple RBC transfusions and red cell exchange (RCE) is poorly described, and unknown in the Canadian context, including at our center. The objective of this study is to describe RBC utilization at our center in a cohort of patients with SCD. Methods: All adult patients with SCD who have received care [inpatient, outpatient, or emergency department (ED)] at the Ottawa Hospital, from January 2006 to May 2019 were identified for study inclusion. Transfusion and health care utilization data was obtained through to December 2021 from clinical, administrative and laboratory databases at the Ottawa Hospital. Results: A total of 273 patients with SCD were identified. The median age for the cohort was 25 years (IQR 19,33) at first visit, with females comprising 53.9% of the cohort. The median duration of follow-up was 8.1 years (IQR 5,12.4). O-positive was the most frequent blood type (41.8%), and 8 (2.9%) individuals were O-negative. The annual RBC and health care utilization for the study cohort is depicted in Figure 1. The total number of hospital visits during the study period was 23127, with a median of 45 visits (IQR 18,100) per patient. 165 patients (60.4%) received 22538 RBC units with a median of 2 units (IQR 1,19) per patient, per year. 86.5% of the RBC units were infused in the outpatient setting, 12.1% in the inpatient setting and 0.8% in the ED. 40.3% of inpatient hospital visits were associated with an RBC transfusion event, compared to 2.4% of ED encounters. The proportion of RBC units transfused that were O-negative was 29.1% (6557 units). 147 patients received 2205 (9.7%) as simple RBC transfusions. The median number of simple RBC units transfused per patient, per year was 1 unit (IQR 1,2). 88 patients received 20333 RBC units during 2702 RCE sessions (median of 14.5 RCE sessions per patient), with 91.5% occurring in the outpatient setting. Of the 88 patients who received RCE, 64 patients (72.7%) had more than one RCE session, 54 patients (61.4%) had more than 5 RCE sessions and 48 patients (54.5%) had more than 10 RCE sessions. The median number of RBC units transfused per RCE session was 7 (IQR 6,9), with a median duration of 30 days (IQR 28,40) between RCE sessions. Conclusions: RBC transfusion was common in our cohort, with the majority of patients having received at least one RBC transfusion. The largest proportion of transfused RBC units stem from RCE use, which represents a small proportion of on our SCD cohort. O-negative units represented a large proportion of units transfused, despite the predominance of non-group O patients, likely due to both differences in donor and patient blood group phenotypes, and recommendations for extended phenotype matching. With pressure on transfusion medicine to provide appropriately matched units and the scarcity of O-negative units, further data accrual on RBC utilization, particularly assessment of indications, requirements for matching, and review of RCE procedures will define further quality improvement interventions to ensure optimal utilization of RBCs.

Clinical approach to mechanical circulatory support in the transplant patient from the Pediatric Heart Transplant Society.

The use of mechanical circulatory support (MCS) for pediatric patients who have undergone heart transplant has grown rapidly in the past decade. This includes support in the immediate post-transplant period and "rescue" therapy for patient later in their transplant course. Extracorporeal membrane oxygenation (ECMO) remains a standard modality of support for intraoperative concerns and for acute decompensation in the immediate post-transplant period. However, both pulsatile and continuous flow ventricular assist devices (VADs) have been used with increasing success in transplant patients for longer durations of support. Centers participating in the Pediatric Heart Transplant Society (PHTS) were queried to provide their internal protocols and rationale for mechanical circulatory support following heart transplant. These protocols coupled with evidence-based literature were used to provide the following description of clinical approaches to MCS in the transplant patient highlighting areas of both broad consensus and significant practice variation.
