Rates of Female Sterilization, Vasectomy, and LARC Placement Before and After the Dobbs Decision: A Retrospective Cohort Study [ID 2683404

INTRODUCTION: Immediately after the Dobbs decision in Ohio, abortion was restricted after detection of a fetal heartbeat. The objective of this study was to characterize changes in utilization of long-acting reversible contraception (LARC) and permanent sterilization (PS) after the abrupt enactment of restrictive abortion legislation. METHODS: We conducted a retrospective cohort study of female and male patients aged 15–55 who underwent permanent sterilization (tubal ligation, salpingectomy, vasectomy) or LARC placement (IUD, contraceptive implant) at a large Northeast Ohio hospital system from January 1, 2022 to December 31, 2022; 6 months before and after Dobbs. Contraception procedure volumes were compared, and patient characteristics were assessed. RESULTS: Pre-Dobbs, 4,247 procedures were identified among females, including 725 (17.1%) PS and 7,449 (81.3%) LARC. Post-Dobbs, the total number of female procedures increased by 15.5% (4,916) and there was a significant increase in the proportion of PS procedures, representing 20.1% of all female procedures (P<.001). Males showed a similar trend, with vasectomies rising from 1,193 to 1,590 procedures. Post-Dobbs, patients undergoing procedures were younger (women, 30.9 years [24.5, 36.8] versus 31.5 [25.2, 36.9]; P=.011; men, 36.6 years [32.9, 39.6] versus 37.2 [34.2, 40.4]; P<.001). Among patients undergoing procedures post-Dobbs, the proportion that reported single relationship status significantly increased for women (57.4% versus 55.9%; P=.028) and men (23.0% versus 18.1%; P=.002). CONCLUSION: This study demonstrates increased utilization of LARC and PS following the Dobbs decision. This rise in PS and demographic changes implies concerns about abortion access, especially among younger reproductive-aged patients. Further research is warranted to understand the driving factors behind these trends.

Projections of Single-level and Multilevel Spinal Instrumentation Procedure Volume and Associated Costs for Medicare Patients to 2050.

Instrumented spinal fusions can be used in the treatment of vertebral fractures, spinal instability, and scoliosis or kyphosis. Construct-level selection has notable implications on postoperative recovery, alignment, and mobility. This study sought to project future trends in the implementation rates and associated costs of single-level versus multilevel instrumentation procedures in US Medicare patients aged older than 65 years in the United States. Data were acquired from the Centers for Medicare & Medicaid Services from January 1, 2000, to December 31, 2019. Procedure costs and counts were abstracted using Current Procedural Terminology codes to identify spinal level involvement. The Prophet machine learning algorithm was used, using a Bayesian Inference framework, to generate point forecasts for 2020 to 2050 and 95% forecast intervals (FIs). Sensitivity analyses were done by comparing projections from linear, log-linear, Poisson and negative-binomial, and autoregressive integrated moving average models. Costs were adjusted for inflation using the 2019 US Bureau of Labor Statistics' Consumer Price Index. Between 2000 and 2019, the annual spinal instrumentation volume increased by 776% (from 7,342 to 64,350 cases) for single level, by 329% (from 20,319 to 87,253 cases) for two-four levels, by 1049% (from 1,218 to 14,000 cases) for five-seven levels, and by 739% (from 193 to 1,620 cases) for eight-twelve levels (P < 0.0001). The inflation-adjusted reimbursement for single-level instrumentation procedures decreased 45.6% from $1,148.15 to $788.62 between 2000 and 2019, which is markedly lower than for other prevalent orthopaedic procedures: total shoulder arthroplasty (-23.1%), total hip arthroplasty (-39.2%), and total knee arthroplasty (-42.4%). By 2050, the number of single-level spinal instrumentation procedures performed yearly is projected to be 124,061 (95% FI, 87,027 to 142,907), with associated costs of $93,900,672 (95% FI, $80,281,788 to $108,220,932). The number of single-level instrumentation procedures is projected to double by 2050, while the number of two-four level procedures will double by 2040. These projections offer a measurable basis for resource allocation and procedural distribution.

Earned outcomes correlate with reliability-adjusted surgical mortality after abdominal aortic aneurysm repair and predict future performance

ObjectiveCumulative, probability-based metrics are regularly used to measure quality in professional sports, but these methods have not been applied to health care delivery. These techniques have the potential to be particularly useful in describing surgical quality, where case volume is variable and outcomes tend to be dominated by statistical “noise.” The established statistical technique used to adjust for differences in case volume is reliability-adjustment, which emphasizes statistical “signal” but has several limitations. We sought to validate a novel measure of surgical quality based on earned outcomes methods (deaths above average [DAA]) against reliability-adjusted mortality rates, using abdominal aortic aneurysm (AAA) repair outcomes to illustrate the measure’s performance. MethodsEarned outcomes methods were used to calculate the outcome of interest for each patient: DAA. Hospital-level DAA was calculated for non-ruptured open AAA repair and endovascular aortic repair (EVAR) in the Vascular Quality Initiative database from 2016 to 2019. DAA for each center is the sum of observed – predicted risk of death for each patient; predicted risk of death was calculated using established multivariable logistic regression modeling. Correlations of DAA with reliability-adjusted mortality rates and procedure volume were determined. Because an accurate quality metric should correlate with future results, outcomes from 2016 to 2017 were used to categorize hospital quality based on: (1) risk-adjusted mortality; (2) risk- and reliability-adjusted mortality; and (3) DAA. The best performing quality metric was determined by comparing the ability of these categories to predict 2018 to 2019 risk-adjusted outcomes. ResultsDuring the study period, 3734 patients underwent open repair (106 hospitals), and 20,680 patients underwent EVAR (183 hospitals). DAA was closely correlated with reliability-adjusted mortality rates for open repair (r = 0.94; P < .001) and EVAR (r = 0.99; P < .001). DAA also correlated with hospital case volume for open repair (r = −.54; P < .001), but not EVAR (r = 0.07; P = .3). In 2016 to 2017, most hospitals had 0% mortality (55% open repair, 57% EVAR), making it impossible to evaluate these hospitals using traditional risk-adjusted mortality rates alone. Further, zero mortality hospitals in 2016 to 2017 did not demonstrate improved outcomes in 2018 to 2019 for open repair (3.8% vs 4.6%; P = .5) or EVAR (0.8% vs 1.0%; P = .2) compared with all other hospitals. In contrast to traditional risk-adjustment, 2016 to 2017 DAA evenly divided centers into quality quartiles that predicted 2018 to 2019 performance with increased mortality rate associated with each decrement in quality quartile (Q1, 3.2%; Q2, 4.0%; Q3, 5.1%; Q4, 6.0%). There was a significantly higher risk of mortality at worst quartile open repair hospitals compared with best quartile hospitals (odds ratio, 2.01; 95% confidence interval, 1.07-3.76; P = .03). Using 2016 to 2019 DAA to define quality, highest quality quartile open repair hospitals had lower median DAA compared with lowest quality quartile hospitals (−1.18 DAA vs +1.32 DAA; P < .001), correlating with lower median reliability-adjusted mortality rates (3.6% vs 5.1%; P < .001). ConclusionsAdjustment for differences in hospital volume is essential when measuring hospital-level outcomes. Earned outcomes accurately categorize hospital quality and correlate with reliability-adjustment but are easier to calculate and interpret. From 2016 to 2019, highest quality open AAA repair hospitals prevented >40 perioperative deaths compared with the average hospital, and >80 perioperative deaths compared with lowest quality hospitals.

The effect of Medicaid expansion on rates of carpal tunnel release: an interrupted time series analysis.

Medicaid expansion through the Affordable Care Act (ACA) has been associated with greater access and utilization of surgical services in underserved populations. However, its impact on use of hand surgical care is less understood. The purpose of this study was to evaluate the association between New York State adoption of the ACA and carpal tunnel release (CTR) procedural volume in Medicaid beneficiaries. We conducted a pooled cross-sectional analysis of patients who underwent CTR using the Healthcare Cost and Utilization Project New York State all-payer database (2010-2018). An interrupted time series (ITS) analysis using an autoregressive integrated moving average model estimated the immediate and long-term impact of Medicaid expansion in January 2014 on CTR procedural volume in Medicaid beneficiaries and uninsured individuals. A total of 112,569 patients were included in the sample. After expansion, we observed an absolute increase of 6% in the share of CTR procedures provided to Medicaid beneficiaries. Policy implementation was associated with an immediate 1.81% increase (95% CI=0.0085, 0.0277; p<0.001) in the probability of Medicaid as the primary payer and an annual increase of 1.68% (95% CI=0.0134, 0.0202; p<0.001) after reform. ITS analysis found this resulted in 4,190 additional CTR procedures in Medicaid beneficiaries than predicted without expansion. Study results suggest New York's adoption of the ACA was associated with an immediate and steady increase in use of outpatient CTR in Medicaid beneficiaries. Most of this increase represented newly treated patients rather than those who were previously uninsured.

Disparities in Access to Outpatient Surgery Related to Removal of Procedures from Medicare's Inpatient Only List.

We assessed the shift from inpatient to outpatient surgical care related to changes to the Inpatient Only List in 2020 and 2021 compared to 2019. The extent to which procedures shift from the inpatient to outpatient setting following removal from Medicare's Inpatient Only List is unknown. Many health systems also encouraged a shift from inpatient to outpatient surgery during the COVID-19 pandemic. Assessing the relative change in outpatient surgical utilization for procedures removed from the Inpatient Only List during COVID-19 would provide empirical data on whether reimbursement policy changes or inpatient capacity needs during the pandemic were more likely to shift care from the inpatient to outpatient setting. We used administrative data from the PINC AI Healthcare Database across 723 hospitals to determine the within-facility relative change in outpatient vs inpatient procedural volume in 2020 and 2021 compared to 2019 using a multivariable conditional fixed-effects Poisson regression model. We also assessed whether outpatient surgical utilization varied by race and ethnicity. Using a multivariable linear probability model, we assessed the absolute change in risk-adjusted 30-day complication, readmission, and mortality rates for inpatient and outpatient surgical procedures. In 2020 and 2021 compared to 2019 respectively, there was a 5.3% (95% CI, 1.4% to 9.5%) and 41.3% (95% CI 33.1% to 50.0%) relative increase in outpatient elective procedural volume. Outpatient procedural volume increased most significantly for hip replacement which was removed from the Inpatient Only List in 2020 (increase in outpatient surgical utilization of 589.3% (95% CI, 524.9% to 660.3%)). The shift to outpatient hip replacement procedures was concentrated among White patients; in 2021, hip replacement procedural volume increased by 271.1% (95% CI, 241.2% and 303.7%) for White patients and 29.5% (95% CI, 24.4% and 34.9%) for Black patients compared to 2019 levels. There were no consistent or large changes in 30-day complication, readmission, or mortality risk in 2020 and 2021 compared to 2019. There was a modest increase in elective outpatient surgeries and a pronounced increase in outpatient orthopedic surgeries which were removed from the Inpatient Only List during the COVID-19 pandemic. Utilization of outpatient surgical procedures was concentrated among White patients.

Work-Related Musculoskeletal Injury Rates, Risk Factors, and Ergonomics in Different Endoscopic Specialties: A Review.

Endoscopy-related musculoskeletal injuries (ERIs) are frequent among gastrointestinal, pulmonary, nasal, and urologic endoscopists, impacting the healthcare system. The present review aims to compare the ERI rates, risk factors, and ergonomic recommendations in the different endoscopic fields. A review was conducted using PubMed and Cochrane Library for articles based on surveys and published until 10 January 2024. Demographic, work, and ERI data from 46 publications were included, covering 10,539 responders. The ERI incidence ranged between 14% and 97%, highlighting the need of intervention independent of the specialties. The neck, back, and shoulder were the most frequent ERI locations, while gender, age, years of experience, and procedure volume the most common risk factors. Ergonomic recommendations suggest concentrating on endoscope design changes, especially in gastrointestinal endoscopy, to increase the comfort, adaptability of the equipment in the operating room, and workflow/institutional policy changes. The inclusion of an ergonomic timeout guarantees the correct equipment positioning, the neutralisation of the endoscopist's posture, and an indirect break between procedures. Ergonomic training to increase awareness and best practice should be promoted, also using new technologies. Future research should concentrate on intervention and comparative studies to evaluate to which extent prevention measures and newly designed equipment could reduce ERI incidence.

Permanent and long-acting reversible contraception volumes at a multihospital system in Ohio before and after Dobbs

ObjectivesImmediately following the Dobbs decision, Ohio prohibited abortion after the detection of fetal cardiac activity. We aimed to characterize changes in the uptake of long-acting reversible contraception (LARC) and permanent contraception following the abrupt enactment of restrictive abortion legislation. Study designWe conducted a retrospective cohort study using electronic medical record data of patients aged 15 to 55 who underwent permanent contraception (tubal ligation, vasectomy) or LARC placement (intrauterine device, contraceptive implant) at a multihospital system in northeast Ohio from January 1, 2022 to Decemeber 31, 2022, 6 months before and after Dobbs. We compared procedure volumes and patient characteristics. ResultsWe identified 4247 tubal ligation and LARC procedures pre-Dobbs, including 725 (17.1%) permanent contraception and 3522 (82.9%) LARC. Post-Dobbs, the total number of tubal ligation and LARC procedures increased by 15.8% (4916), and there was a significant increase in the proportion of permanent contraception, (p < 0.001). Vasectomy volume increased by 33.3% post-Dobbs, from 1193 to 1590 procedures. Compared to pre-Dobbs, patients undergoing contraceptive procedures post-Dobbs were younger (tubal ligation and LARC, 30.9 median years [24.5, 36.8] vs 31.5 [25.2, 36.9], p = 0.011; vasectomy, median 36.6 years [32.9, 39.6] vs 37.2 [34.2, 40.4], p < 0.001) and more likely to report single relationship status (57.4% vs 55.9% for tubal ligation and LARC, p = 0.028% and 23.0% vs 18.1% for vasectomy, p = 0.002). ConclusionsThis study demonstrates increased uptake of contraceptive procedures following the Dobbs decision. This rise in permanent contraception suggests a relationship between abortion policy and contraceptive decision-making, especially among younger patients. ImplicationsIncreased permanent and long-acting reversible contraception procedures following Dobbs reveal shifting contraceptive choices, particularly among younger individuals, indicating a connection between abortion policy and reproductive decisions.

Apheresis practice variation during the COVID-19 pandemic: Results of a survey.

The COVID-19 pandemic affected healthcare delivery across all specialties including apheresis. To describe the changes in apheresis service practices that occurred during the pandemic, the American Society for Apheresis (ASFA) Apheresis Medicine Attending Physician Subcommittee conducted a survey study. A 32-question survey was designed and distributed to 400 ASFA physician members on September 7, 2022. Attending physicians responded to questions about whether and how apheresis service practices changed during the COVID-19 pandemic compared with the time period prior to the pandemic in terms of: (1) procedure types and volumes, (2) patient consultation workflow, and (3) the use of telemedicine. Descriptive analyses were reported as number and frequency of responses. The survey response rate was 13.8% (55/400). Of these respondents, 96.4% (53/55) were attending physicians. The majority of respondents (42/53, 79.2%) indicated that the types of procedures performed during COVID-19 compared to pre-pandemic did not change. Most frequently for apheresis procedure volume, respondents reported: no change in their monthly inpatient volume (21/47, 44.7%) and a decrease in their monthly outpatient volume (28/46, 60.9%). Prior to COVID-19, 75.0% (30/40) of respondents performed consultations at bedside for inpatients and 67.4% (29/43) performed consultations at bedside for outpatients. Bedside consultations decreased in both settings during the pandemic but were still most frequently performed by attending physicians. At the same time, the use of telemedicine increased for 15.4% of survey respondents during COVID-19. Some, but not all, respondents observed or made changes to their apheresis service during the COVID-19 pandemic. A subset of changes, such as increased utilization of telemedicine, may persist.

A 16-Year Analysis of Aesthetic Surgery Volume and Its Association with U.S. Economic Performance

Abstract Goals/Purpose Historically, demand for plastic surgery has been associated with the performance of the United States (US) economy. Over the past two decades, the US has weathered a recession, several presidential election cycles, and has seen a rise in the use and influence of social media. Each of these events has led to varying effects on the economy, which undoubtedly have had an impact on plastic surgery demand and expenditures. Thus, this study aims to evaluate the relationship between indicators of economic performance and the popularity and profitability of aesthetic surgery from 2006 to 2022. Methods/Technique Data from the Aesthetic Society’s (AS) Aesthetic Plastic Surgery National Databank and the American Society of Plastic Surgeons’ (ASPS) Plastic Surgery Statistics Report was collected from 2006 to 2022. Surgical procedures analyzed included the most commonly performed cosmetic surgeries: breast augmentation, breast reduction, mastopexy, abdominoplasty, liposuction, blepharoplasty, facelift, and rhinoplasty. The non-surgical botox injections and dermal fillers were also included. A total of 24 variables were examined, including the 10 procedures and two composite variables—total surgical procedures and total injectables; case change percent difference and patient expenditures percent difference were recorded for each of these. Within the corresponding period, economic indices were collected, including personal disposable income per capita (PDI), consumer price index (CPI), medical care services CPI, average gross domestic product per capita (GDP), and annual average closing prices of the NASDAQ, S&amp;P 500, and the Dow Jones (DOW). Pearson correlation tests were used to analyze the strength of association between each financial indicator and case volumes and expenditures for each procedure included in the ASPS and AS reports. Results/Complications From 2006 to 2020 ASPS data demonstrated GDP year-over-year (YOY) change that was positively correlated with case volume and expenditures across 13 out of the 24 different procedure metrics (54.2%). From 2006 to 2016, AS data was positively correlated with the performance of NASDAQ, S&amp;P500, and DOW in 12 of the 24 procedure metrics (50%). GDP YOY change closely followed suit with positive correlations to 11 variables (45.8%). YOY change of PDI, CPI, and medical care services CPI were less frequently associated amongst both data sets. For ASPS data, YOY medical services CPI change was negatively associated with five variables, indicating that as medical services CPI increased, volume of procedures and expenditures decreased. PDI YOY change was not significantly associated with any variables. In the AS dataset between 2006 and 2016, CPI YOY change was not found to be significantly associated with any variables. Across 2019–2022, CPI YOY and disposable YOY change were found to be significantly associated with three variables each. Conclusion Our study suggests that aesthetic plastic surgery procedures and expenditures are most positively correlated with GDP. Stock market indices are additional financial indicators which have significant positive correlations with plastic surgery case volume and expenditures. Inflation indicators were less frequently correlated. Over this timeframe, several important financial events have occurred including the Great Recession, a stock market selloff in 2015 and 2016, and the COVID-19 pandemic. Each of these events, along with several election cycles and the increasing influence of social media and popular culture, have had variable impacts on consumers and the demand for aesthetic plastic surgery. Plastic surgeons should be familiar with US and global financial markets as they fluctuate with current events. While plastic surgery prices and demand may be difficult to anticipate, this study elucidates several factors that may be used by plastic surgeons as a bellwether for their practice.

Center-level outcomes following elective fenestrated endovascular aortic aneurysm repair in the Vascular Quality Initiative database

ObjectiveHospital volume is associated with mortality after open aortic aneurysm repair. Fenestrated and branched endovascular aortic repair (B-FEVAR) has been increasingly used for repair of complex thoracoabdominal and juxtarenal aneurysms, but evidence of a center-volume relationship is limited. We aimed to measure the association of center volume with in-hospital mortality, postoperative outcomes, and 1-year survival following B-FEVAR. MethodsPatients undergoing elective endovascular thoracoabdominal and complex abdominal aneurysm repair with branch intervention (2014-2021) listed within the national Vascular Quality Initiative Thoracic Endovascular Aortic Repair/Complex EVAR database were analyzed. Centers were grouped into quartiles by mean annual procedure volume. Multivariable regression was used to evaluate the effect of center volume on in-hospital mortality adjusting for baseline and procedural characteristics. Kaplan-Meier estimation, log rank test, and mixed effects Cox regression were used to evaluate 1-year survival. ResultsA total of 4302 adult elective F-BEVAR procedures were identified at a total of 163 centers. In-hospital mortality did not differ by hospital volume (quartile [Q]1 = 35/1059 [3.3%]; Q2 = 30/1063 [2.8%]; Q3 = 33/1120 [2.9%]; and Q4 = 44/1060 [4.2%]; P = .308). The high volume group had a higher rate of major complication (Q1 = 14.9%; Q2 = 12.8%; Q3 = 13.3%; and Q4 = 20.1%; adjusted P < .001). Physician-modified grafts were more frequently employed in high-volume centers (Q1 = 4.5%; Q2 = 18.7%; Q3 = 11.3%; and Q4 = 19.2%; P < .001), with a decreased incidence of any endoleak noted at the end of the procedure (Q1 = 34.9%; Q2 = 32.8%; Q3 = 30.0%; and Q4 = 29.0%; P = .003). In the multivariable analysis, in-hospital mortality was not associated with center volume, comparing very low volume to medium- and high-volume centers (odds ratio [95% confidence interval] vs Q4: Q1 = 1.1 [0.6-1.9], Q2 = 0.6 [0.4-1.1], and Q3 = 0.9 [0.5-1.5]; all P > .05). No significant difference was found in 1-year survival between center volume groups. ConclusionsIn-hospital mortality is not associated with procedure volume within centers performing complex endovascular aortic repair. However, complication rates and endoleak may be associated with procedure volume. Long-term outcomes by annualized procedure volume, specifically graft durability and sac expansion, should be investigated.

Volume and Practice-Setting Shift of Laryngology Procedures During the COVID-19 Pandemic: A Reg-ENT Database Analysis.

The onset of the coronavirus disease 2019 (COVID-19) pandemic changed practice patterns throughout medicine. The purpose of this study is to evaluate changes in the volume and location setting of laryngology procedures after the onset of COVID-19. Retrospective database cohort study. Reg-ENT registry. Retrospective review from 2017 to 2022 of patients who underwent a laryngology procedure identified by procedure code categorized by site of service code-"ambulatory surgical" versus "office" setting. Based on March 2020 as the cutoff point, the procedures were designated as pre-COVID versus COVID time period. A total of 5989 patients underwent laryngology procedures. Forty-two percent more procedures were performed in the COVID period (n = 3780) versus pre-COVID (n = 2209). Pre-COVID, the procedure distribution between office and ambulatory surgical setting was 70% (n = 1546) compared with 30% (663). This shifted to 77% (n = 2920) and 23% (n = 860) during COVID, P = .9. The most common diagnoses associated with laryngology procedures during the study period were vocal fold paralysis 47% (n = 2831), dysphonia 33% (n = 1392), and laryngotracheal stenosis 14% (n = 838). These trends remained in both pre-COVID and COVID time periods. After the start of the pandemic, among patients undergoing laryngology procedures, there was a 93% increase (n = 284-549) in the diagnosis of laryngotracheal stenosis, 70% increase (n = 520-882 patients) in dysphonia and 69% increase (n = 1054-1777) in vocal fold paralysis. An increase in laryngology procedures performed after the onset of the COVID-19 pandemic was identified with an overall procedural shift to the office-setting.

Adoption of a gastroenterology hospitalist model and the impact on inpatient endoscopic practice volume: a controlled interrupted time-series analysis

Background and AimsThe gastroenterology (GI) hospitalist staffing model has multiple potential benefits for the inpatient and outpatient care of GI patients. The GI hospitalist model may improve inpatient endoscopy efficiency via better provider familiarity with management of GI emergencies, hospital systems and workflow, and may also increase outpatient endoscopy capacity by decreasing the need for inpatient coverage by outpatient providers. However, the real-world impact of this model on inpatient and outpatient endoscopic volume remains uncertain. MethodsWe conducted a controlled interrupted time series analysis from September 2018 to March 2020 comparing inpatient endoscopy volume at two high-acuity hospitals within the same academic health system, one of which adopted a two-physician GI hospitalist model in July 2019. We also performed a single interrupted time series analysis of outpatient endoscopic volume of the practice employing GI hospitalists. ResultsAfter implementation of the GI hospitalist model, weekly volume of inpatient endoscopic procedures increased by 10.9 (95% CI: [0.6, 21.2]; p=0.024) compared to a hospital using traditional staffing. Outpatient endoscopic procedure volume also increased by 39.8 per week (95% CI: [-5.78, 85.44]; p=0.09), with no change in the number of physicians performing endoscopy. ConclusionsOur findings demonstrate that introduction of a GI hospitalist model increased inpatient and outpatient endoscopic volume in a large academic center.

Practices and perspectives on advanced diagnostic and interventional bronchoscopy among pediatric pulmonologists in the United States.

Advanced diagnostic bronchoscopy includes endobronchial ultrasound (EBUS) guided transbronchial lung and lymph node biopsies, CT navigation and robotic bronchoscopy. Interventional bronchoscopy refers to procedures performed for therapeutic purposes such as balloon dilation of the airway, tissue debulking, cryotherapy, removal of foreign bodies and insertion of endobronchial valves [1]. For adult patients, these procedures are standard of care [2, 3]. Despite a lack of formalized training, there are numerous case reports and case series describing the use of advanced diagnostic and interventional bronchoscopy techniques in children. The safety and feasibility of EBUS-TBNA, cryotherapy techniques, endobronchial valves among other techniques have been demonstrated in these publications [1, 4-9]. We sought to better understand the current practices and perspectives on interventional and advanced bronchoscopy among pediatric pulmonologists through surveys sent to pediatric teaching hospitals across the United States. We received 43 responses representing 28 programs from 25 states. The highest bronchoscopy procedure volume occurred in the 0-5 years age group. Among our respondents, 31% self-identified as a pediatric interventional/advanced bronchoscopist. 79% believe that advanced and interventional training is feasible in pediatric pulmonology and 77% believe it should be offered to pediatric pulmonary fellows. This is the first study to characterize current practices and perspectives regarding advanced diagnostic and interventional bronchoscopy procedures among pediatric pulmonologists in the United States. Pediatric interventional pulmonology (IP) is in its infancy and its beginnings echo those of the adult IP where only certain centers were performing these procedures.

1075 The Effect of Regional Procedural Preference on Outcomes After Posterior Decompression for Degenerative Cervical Myelopathy: Individual Participant Data Meta-Analysis of a Prospective, Multinational Dataset of 1047 Cases

INTRODUCTION: There is considerable debate regarding the relative effectiveness of laminoplasty vs. laminectomy and fusion for posterior surgical decompression of degenerative cervical myelopathy (DCM). METHODS: Subjects with DCM that underwent posterior decompression was derived from three independent, prospective, multicentre clinical trials (CSM-NA, CSM-I, CSM-Protect). Primary endpoint was change in SF36-PCS (minimum clinically important difference [MCID] 4) at 1yr compared to pre-operative assessment. Secondary endpoints were change in mJOA (MCID 2) score, Neck Disability Index (NDI; MCID 15) score, NDI Pain Intensity score, and SF36-MCS (MCID 4) score. Two comparison cohorts were created: i) laminoplasty (LP) and ii) laminectomy and fusion (LF). One-stage hierarchical mixed-effects meta-analyses with study and treatment exposure as random effects were performed. As subgroup analysis, the influence of procedural volume between LP-predominant sites, LF-predominant sites, and volume-equivalent sites was investigated. RESULTS: From a total of 1047 patients with DCM, 369 patients met eligibility criteria. There was geographic variability in surgical choice with higher rates of laminectomy and fusion in Brazil and Canada and higher laminoplasty rates in Japan and India. USA had similar rates of LF and LP. When compared to LF-predominant sites, LP-predominant sites achieved greater rates of MCID for mJOA at 1yr (85.4% v. 68.7%, p=0.036) with their predominant technique. There were no significant differences in MCID rates of NDI, SF36-PCS, or SF36-MCS. When comparing LF-predominant and LP-predominant sites with USA, a volume equivalent site, there were no significant differences in MCID rates of all outcomes. CONCLUSIONS: Sites that primarily used LP achieved greater rate of MCID in mJOA with laminoplasty than laminectomy with fusion from primarily LF sites. This suggests that experience with either LP or LF can drive outcomes which has interesting healthcare delivery implications.

Aesthetic Surgery &amp; the Indications at A Sub-Urban Tertiary Hospital in Edo State, Nigeria

Background: Aesthetic surgery though growing at an exponential rate in developed countries is still not well developed in Nigeria. Though lately, there has been an increasing demand for cosmetic procedures in Nigeria but still, the practice is still slow growing. Objective: Few reports of the scope of aesthetic surgery are available from the sub region and Nigeria as a whole. In this study we seek to determine the aesthetic procedures and its indications in our centre, a sub urban teaching hospital in Irrua, Edo State, Southern Nigeria. Methods: A retrospective study of all aesthetic surgery cases carried out over a 5-year period – Jan 2019 to December 2023 at Irrua Specialist Teaching Hospital. Data from theatre records and case notes were analysed with respect to age, sex, procedure and indications for surgery done. Descriptive analysis of variables, means and percentages were considered. Results: In the period of study, 1,066 plastic surgery procedures were documented: 34 (3.19%) were for aesthetic indications. Sixteen of the patients (47.1%) were male and 18 (52.9%) female. Age range of patients that had aesthetic surgery was 1 - 60 years and the mean age was 24.1 + 18.08 years. The commonest aesthetic procedure was cleft repair 14 (41.17%) following cleft lip/palate, the rest were scar revisions 6 (17.65%) with the commonest indication being unsightly scar, otoplasties 5 (14.70%) following traumatic injury to the ear, liposuction 3 (8.82%) indicated by lipodystrophy, rhinoplasties 3 (8.82%) post traumatic injury to the nose, mammoplasties 2 (5.88%) which were done post mastectomy, and one (2.94%) cranioplasty following gun-shot orbital injury. Conclusion: There is paucity in the volume of cosmetic procedures in Irrua and the pattern of requests here differs in many respects from western centres. With the current reduced pool of aesthetic surgery, it is advisable to establish an aesthetic surgery sub-unit in most tertiary institutions. This sub-unit should be fully functional including special clinic days, as this could help attract future clients and develop this branch of Plastic Surgery.

Surgical treatment of degenerative stenotic lesions of the lumbar spine. Own experience of using minimally invasive techniques

Lumbar spinal stenosis is a multifactorial progressive condition mainly affecting older individuals, characterized by narrowing of the natural anatomical pathways passage of nerve structures, resulting in typical clinical symptoms. The disease affects about 103 million people in worldwide with an incidence of absolute lumbar spinal stenosis 19.4% among individuals aged 60-69 years. In the United States, about 600,000 surgical interventions for lumbar spinal stenosis are performed annually. This disease is one of the most common causes of lumbar pain and lower limbs in the elderly individuals, accompanied by claudication and ultimately leading to disability. The main cause of clinical symptoms of the lumbar spinal stenosis is the discrepancy between the sizes of nerve structures and their osteofibrous sheaths, resulting from gradually developing degenerative-dystrophic changes. Objective: To compare the outcomes of surgical treatment of patients with degenerative stenotic lesions of the lumbar spine using open and minimally invasive methods. Materials and methods. The results of surgical treatment of 97 patients with lumbar spinal stenosis aged from 28 to 81 years on the basis of the Department of Minimally Invasive and Laser Spinal Neurosurgery of the State Institution " A.P. Romodanov Neurosurgery Institute, Ukraine", " Neurosurgical Department №20 of Vinnytsia Regional Clinical Psychoneurological Hospital named after Acad. O.I. Yushchenko" of Vinnytsia Regional Council and "Spinex" Medical Center following all clinical research protocols. Patients were divided into four groups depending on the surgical intervention method. Results. The development of concepts regarding the mechanisms of occurrence and treatment methods of lumbar spinal stenosis are highlighted, as well as personal experience of using minimally invasive treatment techniques for this pathology in combination with the use of the ERAS (Enhanced Recovery After Surgery) protocol of perioperative patient management. It was found that the duration of hospital stay for patients with lumbar spinal stenosis statistically significantly desreased when using minimally invasive decompression (p≤0.05) and the ERAS rehabilitation protocol (p≤0.05). When comparing the average length of stay in the hospital of patients of the four groups, a statistically significant (p≤0.05) shorter length of stay in the hospital was observed for patients who underwent minimally invasive decompression using the ERAS rehabilitation protocol. The greatest reduction in pain intensity (according to the Numeric Pain Scale (NPS)) at 6 months post- intervention and rehabilitation was also noted in patients of this group. Conclusions. The use of minimally invasive techniques, the correct choice of surgical procedure volume (interbody fusion is desirable in surgery for degenerative spinal diseases) combined with Enhanced Recovery after Surgery protocol (ERAS) significantly improves postoperative well-being of patients, accelerates patient mobilization, and reduces the length of stay in the hospital.
