Background:
Placenta accreta spectrum (PAS) refers to a disease of morbidly adherent trophoblastic tissue invading into the myometrium of the gravid uterus. The incidence of PAS has been rapidly increasing in recent years. Risk factors include previous uterine surgery, including cesarean delivery, and placenta previa. Patients with antenatally suspected PAS often undergo planned hysterectomy at cesarean delivery. Surgery for PAS is associated with significant maternal morbidity and mortality.
The 2018 joint consensus statement by the American College of Obstetricians and Gynecologists (ACOG) and Society for Maternal-Fetal Medicine (SMFM) recommends the delivery timing for patients with PAS at 34 0/7–35 6/7 weeks of gestation as a Level 1A, strong recommendation based on high-quality evidence (Obstetric Care Consensus No.7, published 12/2018). The objective of this study was to examine the influence of their recommendation on delivery timing for PAS in real-world practice.

Methods:
This retrospective cohort study queried the Healthcare Utilization Cost and Utilization Project’s National Inpatient Sample. The study population was 5,655 patients with a diagnosis of both PAS and placenta previa who underwent cesarean delivery from 1/2016-12/2019. The study period was grouped into pre-consensus period (1/2016-12/2018) and post-consensus period (1/2019-12/2019). A quasi-experimental method with Difference-in-Difference analysis was fitted to examine the change in delivery timing, grouped as early-delivery (&lt;34 weeks), recommended-delivery (34 0/7-35 6/7 weeks), and late-delivery (≥36 weeks).

Results:
At the cohort level, the number of late-delivery decreased by 15.1% and the number of early- delivery increased by 12.8% in the post-consensus period (P=0.001). When stratified by the severity of PAS, more prominent change occurred in severe forms of PAS (increta/percreta) with 37.7% relative-decrease in late-delivery and 13.2% relative-increase in recommended-delivery (P=0.002). When increta/percreta cases were further restricted to the elective admission cases, a marked shift in delivery timing occurred towards recommended-delivery from 32.2% to 51.3% (59.3% relative-increase) whereas late-delivery decreased significantly from 23.5% to &lt;10% (78.3% relative-decrease; P&lt;0.001).

Discussion:
This national-level assessment in the United States suggests that the delivery timing of patients with severe PAS is rapidly shifting to 34 0/7-35 6/7 weeks following the ACOG-SMFM consensus recommendation. Delivery beyond this recommended timing appears to rarely be planned in suspected placenta increta/percreta.
Key limitations of the study included unmeasured bias with a lack of information on exact shared decision-making discussion for the timing of surgery and preoperative diagnosis. Generalizability in different populations was not assessed.

Abstract Title: Postpartum Contraception Decision Making Among Adolescent Mothers 

Background 

Adolescent mothers are more likely to experience short-interval repeat pregnancies than their non-adolescent counterparts, placing them at risk for both pregnancy-related morbidity and adverse socioeconomic outcomes. A previous study in our dyadic adolescent-mother baby medical home showed an association between long-acting contraception (LARC) use and decreased repeat pregnancy, but the reasons that adolescent mothers choose their subsequent contraceptive methods is not well elucidated. 

Methods 

We conducted semi-structured, in-depth phone interviews of 6 month postpartum adolescent women regarding contraceptive choice between 6/16/2020 and 11/16/2020. We recruited participants during their 6 week postpartum visit at the Young Mother’s Clinic, a dyadic primary care medical home located at the Children’s Hospital Colorado. All women who presented for their 6 week postpartum visit during the study period were invited to enroll. 

Twenty-one patient interviews were completed. Each interview was independently coded by two reviewers. All interview transcripts were coded to create a matrix outlining common themes related to contraceptive choice. These codes were then looked at further based on subgroup of contraceptive type and race/ethnicity. 

Results 

Multiple themes emerged upon performing rapid qualitative analysis. Most participants cited an inability to remember to take a daily pill as the reason they did not choose OCPs as their birth control method. Those who did not choose an IUD or implant cited invasiveness as reason for refusal. Participants chose methods other than Depo Provera because they felt that frequent appointments were inconvenient. Conversely, participants who chose the IUD/Implant cited its efficacy, convenience, and menses suppression as reasons for their decision. Those who chose Depo Provera favored its ease of use and menses suppression as well. Pregnancy plans were mentioned by several Hispanic/Latino participants as influencing selection of contraceptive methods, but never by non-Hispanic/Latino participants. Perceived efficacy, duration, and positive side effects were mentioned relatively more frequently by non-Hispanic/Latino participants as compared to Hispanic/Latino participants. 

Conclusion 

The data provided by this study highlights factors that influence adolescent mothers’ contraception decisions. This insight can be used to inform patient-centered contraception counseling specific to this population. 



Postpartum Contraception Decision Making Among Adolescent Mothers

Introduction: Multiple studies have demonstrated racial and ethnic disparities in pregnancy-related outcomes in the United States, and disparities in opioid pain management among different races and ethnicities have also been thoroughly documented. However, few studies have evaluated these disparities in the postpartum setting. We evaluated racial and ethnic disparities in postpartum opioid prescription at a high-volume tertiary care center before and after standardized opioid prescription guidelines were implemented. 

Methods: We conducted a retrospective study of all vaginal deliveries between August 14, 2017 and September 17, 2017, before guideline implementation, and between April 9, 2018 and May 4, 2018, after guideline implementation. We categorized patients into: Non-Hispanic Black, Non-Hispanic White, Hispanic, and Non-Hispanic Other. From medical records we collected demographic information, pain score data, inpatient opioid consumption, and oxycodone prescribed (in morphine milligram equivalents [MME]) upon discharge. 

Results: 560 patients were included, 282 pre-intervention and 278 post-intervention. Opioids administered in the first 24 hours of postpartum admission were 12.6 MME pre-intervention and 6.70 MME post-intervention, and the amount of opioids prescribed for home use were 125 MME pre-intervention and 28 MME post-intervention. There were no statistically significant differences in these measures between racial-ethnic groups before or after the intervention, and there were no significant differences between racial-ethnic groups in how often post-intervention guidelines were followed. 

Conclusion: Standardized prescription guidelines successfully decreased both inpatient and outpatient opioid consumption while maintaining equity among racial groups. Future studies may explore disparities in cesarean section patients, as these patients typically require larger amounts of opioids.

Background 

Near-term follow-up after evaluation in the emergency room for minor ophthalmic concerns can impose logistical challenges for patients and ophthalmology practices. While ophthalmic telemedicine has been used for screening and triage, its feasibility and safety for follow-up after presentation to the emergency department (ED) has not been reported. This study describes the initial results of a novel, newly-implemented Virtual Emergency Department Follow-Up (VEDFU) clinic at Mass Eye and Ear (MEE), a tertiary eye care center in Boston, MA. 

Methods

This was a retrospective, cross-sectional study of 145 clinical encounters from December 6, 2021 to July 1, 2022 in the VEDFU. Inclusion criteria included patients discharged from the MEE ED who required near-term follow-up for diagnoses deemed suitable for the virtual clinic, lived within Massachussets, and consented to virtual care. The primary outcome measures included mode of telemedicine encounter (video or phone call), missed appointment rate, documentation of clinical exam findings, clinical diagnoses, time interval between ED encounter and subsequent virtual follow-up, and referrals after initial telemedicine follow-up (stratified by urgency, subspecialty, and reason for follow-up). 

Results

A total of 145 visits scheduled in the EDFU were included. The mean age was 38.1 years (SD 14.2) and 78 (53.8%) were men. The no-show rate was 31.7%. The mean interval time between ED evaluation and virtual follow-up was 8.3 days (SD 3.9). Of the 99 completed visits, 15 were telephone calls and 84 were video visits. The most common diagnoses were conjunctivitis, chalazion, corneal abrasion, and subsequent encounter after removal of corneal foreign body. After virtual follow-up, 23 patients (23.2%) had subsequent referrals, and no patients returned to the ophthalmic ED.

Conclusion

A novel virtual follow-up program for ophthalmic ED patients enabled safe and timely telemedical re-examination for a range of minor indications without any patients necessitating return to the ED. To our knowledge, this is the first program of its kind and may serve as a model for other medical and surgical subspecialties with high rates of ED referrals, limited clinic availability, and diagnoses that can be managed safely through virtual visits. Larger, longitudinal studies are warranted to further validate ophthalmic telemedicine as an alternative avenue for post-acute near-term follow-up care.

Background
In the field of orthopedic surgery, women have been historically underrepresented. In this analysis, we sought to determine the relative proportion of women amongst active orthopedic surgeons by graduation year and explore related trends.
Methods
Utilizing the Centers for Medicare and Medicaid Services, the investigators were able to acquire the Physician Compare National Downloadable File July 2022 dataset for active physicians who indicated “orthopedic surgery” as their primary specialty. Physicians were queried by graduation year, gender, and state of practice, of which duplicates were removed. Physicians who graduated within the past 7 years (from 2016-2022) were excluded from this analysis to retain only the attending physician population. This query yielded 21,320 orthopedic surgeons. Five-year intervals were used to measure the average proportion of female orthopedic surgeons.
Results
There were 1,477 (6.92%) female and 19,843 male (93.1%) practicing orthopedic surgeons in the United States with medical school graduation dates between 1953-2015. Between graduation years 2011-2015, 12.2% (421/3463) were female. From 2006-2010, 10.7% (346/3224) were
female; 2001-2005, 8.40% (160/2656) were female; 1996-2000, 6.02% (160/2656) were female; 1991-1995, 5.05% (135/2674) were female; 1986-1990, 3.52% (87/2475); 1981-1985, 2.47% (48/1945) were female; 1976-1980, 1.39% (15/1080) were female; 1971-1975, 2.14% (11/515) were female; 1966-1970, 0.93% (2/215) were female; 1961-1965 1.39% (1/72) were female; and before 1961, 0% (0/12) graduates were female. Additionally, geographic trends were recognized by state, with the highest proportions of active female orthopedic surgeons in Hawaii (14.1%, 12/85) and the District of Columbia (13.6%), and the lowest proportions in Nebraska (2.7%, 4/148) and Alaska (0%, 0/72) .
Conclusion
These basic results indicate the proportion of female orthopedic surgery graduates is increasing, yet longstanding gender inequities in orthopedic surgery training remain.

Background
Acoustic neuromas, also known as vestibular schwannomas, are benign tumors of the vestibulocochlear nerve typically presenting with hearing loss. More common in adults, these are also associated with neurofibromatosis type 2 in children. Once diagnosed via audiogram and MRI, options include conservative management, radiotherapy, or surgical resection. Prior studies have demonstrated disparities such as Black patients tending to be managed conservatively despite larger tumor size at diagnosis and having increased mortality when managed surgically. Given such disparities, this study aims to investigate further socioeconomic factors potentially impacting acoustic neuroma management to facilitate systemic healthcare changes for equitable outcomes.

Methods
Acoustic Neuroma patient data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database and analyzed using binary logistic regression in SPSS 27.0. Demographic variables including sex, age, race, income, and county attributes were analyzed with respect to the dependent variable of initial management with surgery. Demographic groupings were determined using preset SEER coding and United States demographic data.

Results
This was a retrospective analysis of 19,624 patients diagnosed with acoustic neuroma from 2000 to 2019, which consisted of 9,426 males (48.1%) and 10,198 females (51.9%). Factors that predicted whether a patient’s initial treatment was surgery included age between 18 and 64 (p<0.001), race other than Black (p<0.001), income between $60,000 and $75,000 (p<0.001), and living in a county with a population less than one million (p<0.001).

Conclusion
This study indicates that multiple demographic factors predict the course of care for patients with acoustic neuromas. Noticeably, Black patients were treated more conservatively, as they were less likely to be treated with surgery. Other demographic variables in this study indicate that there are likely other factors that play a role in determining a patient’s clinical course, which may include clinical judgment, coexisting comorbidities, and access to non-surgical modalities of care. These findings can inform health system policy on potential shortcomings of care provided to at-risk populations.

Manuscript - Sounds Like Surgery: Socioeconomic and Demographic Predictors of Acoustic Neuroma Treatment

Objective: Biologic medications are novel therapeutics in the treatment of Autoimmune Inner Ear Disease (AIED), an etiology of Sensorineural Hearing Loss (SNHL). The goal of this study is to review the currently available literature on the efficacy of biologic medications on autoimmune-mediated hearing loss and associated symptomology among patients with AIED. 

Methods: A systematic review of Pubmed, Scopus, Cochrane, and Web of Science databases was conducted to identify studies investigating the impact of biologic medications on hearing outcomes. Bias assessment was independently conducted by three authors and studies were stratified based on risk of bias. 

Results: Of 174 unique abstracts screened, 13 articles met inclusion criteria for formal review. One randomized control trial, eight prospective cohort studies, and four retrospective cohort studies were included. Seven biologic medications, Etanercept, Infliximab, Adalimumab, Golimumab, Rituximab, Anakinra, and Canakinumab, were identified targeting three unique molecular targets, TNF-a, CD20, and IL-1. 

Conclusion: The effects of biologic medications in treating SNHL was highly variable without clear efficacy of a drug or drug category, likely due to rarity of disease, multifactorial etiologies of AIED, and cohort heterogeneity. However, several medications alleviate symptoms associated with AIED, such as vertigo and tinnitus. While biologic medications may be promising therapeutics in AIED patients, the evidence is currently inconclusive. Large-scale randomized control trials and prospective cohort reviews are required to establish the efficacy of biologic medications in treating hearing loss.

Introduction: Endoscopic surveillance guidelines for patients with repaired esophageal atresia (EA) rely primarily on expert opinion. Prior to embarking on a prospective EA surveillance registry, we sought to understand EA surveillance practices within the Eastern Pediatric Surgery Network (EPSN). 
Methods: An anonymous, 23-question Qualtrics survey was emailed to 181 physicians (surgeons and gastroenterologists) at 19 member institutions. Likert scale questions gauged agreement with international EA surveillance guideline-derived statements. Multiple-choice questions assessed individual and institutional practices.
Results: The response rate was 77%. Most respondents (80%) strongly agree or agree that EA surveillance endoscopy should follow a set schedule, while only 36% claimed to perform routine upper GI endoscopy regardless of symptoms. Many institutions (77%) have an aerodigestive clinic, even if some lack a multi-disciplinary EA team. Most physicians (72%) expressed strong interest in helping develop evidence-based guidelines. 
Conclusions: Our survey reveals physician agreement with current guidelines but weak adherence. Surveillance methods vary greatly, underscoring the lack of evidence-based data to guide EA care. Aerodigestive clinics may help implement surveillance schedules. Respondents support evidence-based protocols, which bodes well for care standardization. Results will inform the first multi-institutional EA databases in the United States (US), which will be essential for evidence-based care.

Background
Preoperative marking is an essential safety practice to prevent ‘never’ events, including wrong site surgery. Moreover, the Joint Commission regulations of Universal Protocol require that patients be marked to indicate the operative site. Marking typically occurs with a pen or marker that may be disposable or reusable. Previous studies have demonstrated that methicillin-resistant staphylococcus aureus (MRSA) can survive in the dark, moist, capped environment of the marking pen and thus, could plausibly be a nidus for transmission from patient to patient. The Joint Commission has established no increased risk of postoperative infection with these markings. With this study, we aimed to determine the colonization of surgical marking pens in the plastic surgery population.

Methods
Two marking pens from five different attending plastic surgeons at a single institution were cultured in standard fashion for aerobic and anaerobic growth. All pens were used repeatedly in office settings for performing patient markings. Those same ten marking pens were then used to mark incision sites on mock patients. Standard povidone-iodine prepping was then performed in a paint only fashion over the skin markings and cultures were again taken. A control group consisted of cultures from five sterile pens from the operating room. Each sterile pen was opened, uncapped, and then swabbed. All twenty-five cultures were analyzed in the hospital laboratory in a blinded fashion.

Results
The five control pens revealed no bacterial growth. Of the ten direct pen cultures, two samples grew coagulase-negative staphylococci and one culture contained pseudomonas aeruginosa. The ten-patient marked and prepped specimens showed 8 negative cultures and two with coagulase-negative staphylococci. Although pseudomonas was detected on standard pen culture, no pseudomonal growth was present in any of the samples after patient marking and prepping with povidone-iodine.

Conclusion
Our findings reaffirm that marking pens may be vehicles for bacterial transmission and expands upon previous studies by describing the presence of bacterial colonization on marking pens even after surgical site preparation with povidone-iodine.
