Building a Cohort of Transgender and Nonbinary Patients from the Electronic Medical Record.

Purpose: Sexual orientation, gender identity, and sex recorded at birth (SOGI) have been routinely excluded from demographic data collection tools, including in electronic medical record (EMR) systems. We assessed the ability of adding structured SOGI data capture to improve identification of transgender and nonbinary (TGNB) patients compared to using only International Classification of Diseases (ICD) codes and text mining and comment on the ethics of these cohort formation methods. Methods: We conducted a retrospective chart review to classify patient gender at a single institution using ICD-10 codes, structured SOGI data, and text mining for patients presenting for care between March 2019 and February 2021. We report each method's overall and segmental positive predictive value (PPV). Results: We queried 1,530,154 EMRs from our institution. Overall, 154,712 contained relevant ICD-10 diagnosis codes, SOGI data fields, or text mining terms; 2964 were manually reviewed. This multipronged approach identified a final 1685 TGNB patient cohort. The initial PPV was 56.8%, with ICD-10 codes, SOGI data, and text mining having PPV of 99.2%, 47.9%, and 62.2%, respectively. Conclusion: This is one of the first studies to use a combination of structured data capture with keyword terms and ICD codes to identify TGNB patients. Our approach revealed that although structured SOGI documentation was <10% in our health system, 1343/1685 (79.7%) of TGNB patients were identified using this method. We recommend that health systems promote patient EMR documentation of SOGI to improve health and wellness among TGNB populations, while centering patient privacy.

A Single Center Review of COVID-19 Testing and Vaccination in the Transgender and Nonbinary Population.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected transgender and nonbinary (TGNB) persons. We evaluated COVID-19 testing and vaccination rates among TGNB patients at our institution. Methods: We compared COVID-19 testing and vaccination rates between TGNB patients and a cisgender population matched by age, race, and ethnicity. Data were collected through September 22, 2021. Demographic variables, testing rates, and vaccination rates were collected. Descriptive statistics were calculated, and regression was performed on outcomes of interest: any vaccination dose, at least one test, and at least one positive test. Gender modality was the exposure of interest. Results: There were 5050 patients: 1683 cisgender men, 1682 cisgender women, and 1685 TGNB individuals. TGNB patients were more likely to be on Medicaid/Medicare and more likely to be single. The number of patients with at least one test was similar between TGNB (n = 894, 53.1%) and cisgender (n = 1853, 55.1%) groups. The number of patients who had at least one positive test was higher among cisgender patients (n = 238, 7.1%) compared with TGNB patients (n = 73, 4.3%). Vaccination rates were significantly greater among TGNB patients. Compared with cisgender patients, TGNB patients had greater odds of vaccination (adjusted odds ratio [aOR] = 1.25 [95% confidence interval; CI 1.06-1.48]). Compared with cisgender patients, TGNB patients had lower odds of having at least one positive COVID-19 test (aOR = 0.51 [95% CI 0.36-0.72]). Conclusion: Our institutional experience found that vaccination rates for TGNB patients were higher and COVID-19 positivity lower than for cisgender patients.

Top Surgery and Chest Dysphoria Among Transmasculine and Nonbinary Adolescents and Young Adults.

Importance: Transgender and nonbinary (TGNB) adolescents and young adults (AYA) designated female at birth (DFAB) experience chest dysphoria, which is associated with depression and anxiety. Top surgery may be performed to treat chest dysphoria. Objective: To determine whether top surgery improves chest dysphoria, gender congruence, and body image in TGNB DFAB AYA. Design, Setting, and Participants: This is a nonrandomized prospective cohort study of patients who underwent top surgery between December 2019 and April 2021 and a matched control group who did not receive surgery. Patients completed outcomes measures preoperatively and 3 months postoperatively. This study took place across 3 institutions in a single, large metropolitan city. Patients aged 13 to 24 years who presented for gender-affirming top surgery were recruited into the treatment arm. Patients in the treatment arm were matched with individuals in the control arm based on age and duration of testosterone therapy. Exposures: Patients in the surgical cohort underwent gender-affirming mastectomy; surgical technique was at the discretion of the surgeon. Main Outcomes and Measures: Patient-reported outcomes were collected at enrollment and 3 months postoperatively or 3 months postbaseline for the control cohort. The primary outcome was the Chest Dysphoria Measure (CDM). Secondary outcomes included the Transgender Congruence Scale (TCS) and Body Image Scale (BIS). Baseline demographic and surgical variables were collected, and descriptive statistics were calculated. Inverse probability of treatment weighting (IPTW) was used to estimate the association of top surgery with outcomes. Probability of treatment was estimated using gradient-boosted machines with the following covariates: baseline outcome score, age, gender identity, race, ethnicity, insurance type, body mass index, testosterone use duration, chest binding, and parental support. Results: Overall, 81 patients were enrolled (mean [SD] age, 18.6 [2.7] years); 11 were lost to follow-up. Thirty-six surgical patients and 34 matched control patients completed the outcomes measures. Weighted absolute standardized mean differences were acceptable between groups with respect to body mass index, but were not comparable with respect to the remaining demographic variables baseline outcome measures. Surgical complications were minimal. IPTW analyses suggest an association between surgery and substantial improvements in CDM (-25.58 points; 95% CI, -29.18 to -21.98), TCS (7.78 points; 95% CI, 6.06-9.50), and BIS (-7.20 points; 95% CI, -11.68 to -2.72) scores. Conclusions and Relevance: Top surgery in TGNB DFAB AYA is associated with low complication rates. Top surgery is associated with improved chest dysphoria, gender congruence, and body image satisfaction in this age group.

National Trends in Gender-Affirming Surgical Procedures: A Google Trends Analysis.

BACKGROUND: There has been a significant increase in the volume of gender-affirming surgical (GAS) procedures over the past decade. The objective of this paper is to use online search data from Google Trends (GT) to describe national search trends for GAS procedures. METHODS: GT was queried for search terms relating to GAS from January 2004 to February 2021. The 19 selected keywords covered a broad range of GAS topics. United States (US) search interest was collected as relative search volumes (RSVs) and then analyzed by geographic region. The number of plastic surgery providers offering GAS and academic surgery centers was collected from the World Professional Association for Transgender Health (WPATH) and Trans-health.com. RSVs were analyzed by metro area to determine the relationship between search demand and personal income. State Medicaid policies for transgender health services were also collected. RESULTS: All search terms demonstrated a positive increase in RSVs over time except "sex reassignment surgery" and "penectomy". The Mountain/Pacific and East South Central/West South Central had the greatest search volume for GAS and most providers offering care. The East South Central/West South Central region​​ ranked last for providers offering care, despite the relatively high search interest. This region also had no states with explicit Medicaid policies covering gender-affirming care. Metro areas in the top five for RSV but bottom quartile for per capita personal income were identified. CONCLUSIONS: Online search interest for GAS-related terms has increased. Search interest for GAS has regional variation and did not show a specific pattern with provider availability.

A Single-Center Study of Adherence to Breast Cancer Screening Mammography Guidelines by Transgender and Non-Binary Patients.

BACKGROUND: Adherence to screening guidelines among transgender and non-binary (TGNB) populations is not well studied. This study examines breast cancer screening patterns among TGNB patients at an urban academic medical center. METHODS: Demographic information, risk factors, and screening mammography were collected. Mammography rates were calculated in populations of interest according to national guidelines, and mammogram person-years were also calculated. Univariate and multivariate logistic regression was performed. RESULTS: Overall, 253 patients were analyzed: 193 transgender women and non-binary people designated male at birth (TGNB DMAB) and 60 transgender men and non-binary people designated female at birth (TGNB DFAB). The median (interquartile range) age was 53.2 years (42.3-62.6). Most patients had no family history of breast cancer (n = 163, 64.4%) and were on hormone therapy (n = 191, 75.5%). Most patients where White (n = 164, 64.8%), employed (n = 113, 44.7%), and had public insurance (n = 128, 50.6%). TGNB DFAB breast screening rates were low, ranging from 2.0 to 50.0%, as were TGNB DMAB screening rates, ranging from 7.1 to 47.6%. The screening rates among the TGNB DFAB and TGNB DMAB groups did not significantly differ from one another. Among TGNB DFAB patients, univariate analyses showed no significant predictors for mammography. Among TGNB DMAB patients, not being on hormone therapy resulted in fewer odds of undergoing mammography. There were no significant findings on multivariate analyses. CONCLUSION: Mammography rates in the TGNB population are lower than institutional and national rates for cisgender patients, which are 77.3% and 66.7-78.4%, respectively. Stage of transition, organs present, hormone therapy, and risk factors should be considered to guide screening.

Implantation and Control of Wireless, Battery-free Systems for Peripheral Nerve Interfacing.

Peripheral nerve interfaces are frequently used in experimental neuroscience and regenerative medicine for a wide variety of applications. Such interfaces can be sensors, actuators, or both. Traditional methods of peripheral nerve interfacing must either tether to an external system or rely on battery power that limits the time frame for operation. With recent developments of wireless, battery-free, and fully implantable peripheral nerve interfaces, a new class of devices can offer capabilities that match or exceed those of their wired or battery-powered precursors. This paper describes methods to (i) surgically implant and (ii) wirelessly power and control this system in adult rats. The sciatic and phrenic nerve models were selected as examples to highlight the versatility of this approach. The paper shows how the peripheral nerve interface can evoke compound muscle action potentials (CMAPs), deliver a therapeutic electrical stimulation protocol, and incorporate a conduit for the repair of peripheral nerve injury. Such devices offer expanded treatment options for single-dose or repeated dose therapeutic stimulation and can be adapted to a variety of nerve locations.

Surgical management of female genital mutilation-related morbidity: A scoping review.

BACKGROUND: Over 200 million women and girls worldwide have suffered from the partial to total removal of external female genitalia for nonmedical purposes, referred to as female genital mutilation (FGM). Survivors of FGM may develop debilitating physical and psychological long-term sequelae. This is the first study to examine the scope of the extant surgical literature on the management of FGM-related morbidity. METHODS: A systematic scoping review of five major research citation databases was conducted. RESULTS: A total of 190 articles from 29 countries met the inclusion criteria. The majority (76%) were primary source articles and from obstetrics and gynecology literature (71%). Reported interventions for FGM-related morbidity were defibulation, cyst excision, clitoral and vulvar reconstruction, urological reconstruction, peripartum procedures, labial adhesion release, and reinfibulation. CONCLUSIONS: Surgery for FGM complications spans multiple specialties, which suggests multidisciplinary collaboration benefit. Plastic and reconstructive surgeons have a clear role in the multidisciplinary care team for these patients. This scoping review identified a paucity of high-quality evidence with respect to functional quality of life outcomes and long-term follow-up.

Association of Chest Dysphoria With Anxiety and Depression in Transmasculine and Nonbinary Adolescents Seeking Gender-Affirming Care.

PURPOSE: The purpose of this study was to determine the existence and strength of association between chest dysphoria and mental health in transmasculine and nonbinary adolescents. METHODS: This is a cross-sectional cohort study of transmasculine and nonbinary adolescents designated female at birth between 12 and 18 years old. None had undergone prior top surgery. Patients complete the Chest Dysphoria Measure and Youth Inventory-4 (YI-4) upon presentation to our institution. Outcomes were retrospectively reviewed. The primary outcome of interest was the association between chest dysphoria and anxiety and depression symptom severity, as measured by the YI-4. RESULTS: One hundred fifty-six patients met inclusion criteria. Mean age was 15.3 years (standard deviation [SD] = 1.7). Most patients identified as transmasculine (n = 132); 18 identified as nonbinary and 6 as questioning. Mean (SD) YI-4 symptom severity scores were 10.67 (6.64) for anxiety and 11.99 (7.83) for depression. Mean (SD) Chest Dysphoria Measure composite score was 30.15 (9.95); range 2-49. Chest dysphoria was positively correlated with anxiety (r = .146; p = .002) and depression (r = .207; p < .001). In multivariate linear regression models, chest dysphoria showed a significant, positive association with anxiety and depression, after accounting for gender dysphoria, degree of appearance congruence, and social transition status. CONCLUSIONS: Chest dysphoria is associated with higher anxiety and depression in transmasculine and nonbinary adolescents designated female at birth. This association is independent of level of gender dysphoria, degree of appearance congruence, and social transition status. Treatment options aimed at alleviating chest dysphoria should be made accessible to adolescents and tailored to individual needs.

Mastectomy and Chest Masculinization in Transmasculine Minors: A Case Series and Analysis by Ethical Principles.

ABSTRACT: Mastectomy for chest masculinization is a commonly performed gender-affirming surgery in minor patients, a vulnerable population with unique developmental and psychosocial needs. We aimed to use principles of medical ethics (eg, autonomy, beneficence, nonmaleficence, and justice) as a framework to analyze preoperative clinical decision making by pediatric plastic surgeons who work with transmasculine and nonbinary adolescents designated female at birth presenting for chest masculinization. Two patients were selected for inclusion in this case series based on the senior author's (J.F.C.) clinical experience. A retrospective chart review was conducted to extract relevant psychosocial and clinical information from clinic notes and supplemental documentation (eg, letters from outside providers) available in the electronic medical record. In case A, a 17-year-old patient presented to a plastic surgery clinic with mixed parental support and restrictive insurance requirements. In case B, a 16-year-old patient presented to the emergency room after an attempt to remove his own breasts. The cases highlight the role of the plastic surgeon in advocating for adolescent autonomy and justice by facilitating shared family decision making and navigating barriers to care. In addition, we recommend multidisciplinary care, including trusted, transcompetent mental health professionals, to ensure beneficence and nonmaleficence by providing timely care when appropriate.

Influence of Self-Perceived Vulvar Appearance on Female Sexual Function.

BACKGROUND: Female sexual function is a complex model of biological and nonbiological factors. The impact of self-perceived vulvar appearance on female sexual function is not well understood. OBJECTIVES: The aim of this study was to determine the influence of vulvar appearance on sexual function in adult women. The primary aim was to assess the relation between self-perceived vulvar appearance and sexual function. The secondary aim was to assess the influence of prior genital procedures on vulvar appearance and sexual function. METHODS: An observational study of adult women was conducted utilizing Amazon Mechanical Turk, an online crowdsourcing platform. The survey instrument included demographic information, subjective vulvar appearance measures, and the Female Sexual Function Index (FSFI) questionnaire. RESULTS: Out of 398 respondents, 148 (37.2%) reported concern about their vulvar appearance and 134 (33.7%) reported a history of genital cosmetic procedures. Women who were uncomfortable with their vulvar appearance had lower FSFI scores than those comfortable with their vulvar appearance, 24.6 vs 27.0 (P = 0.01), respectively. Among women uncomfortable with their vulvar appearance, 70.9% of subjects met the criteria for sexual dysfunction. Women who were uncomfortable with their vulvar appearance were significantly more at risk of sexual dysfunction (adjusted odds ratio: 2.43; 95% CI: 1.46-4.10; P < 0.001). Women with a history of cosmetic genital procedures were significantly more at risk of sexual dysfunction (adjusted odds ratio: 2.46; 95% CI: 1.43-4.23). CONCLUSIONS: Women who are uncomfortable with their vulvar appearance had higher rates of sexual dysfunction. Women seeking cosmetic genital procedures should be screened for sexual dysfunction to facilitate realistic expectations and optimal care.

Advanced Materials in Wireless, Implantable Electrical Stimulators That Offer Rapid Rates of Bioresorption for Peripheral Axon Regeneration.

Injured peripheral nerves typically exhibit unsatisfactory and incomplete functional outcomes, and there are no clinically approved therapies for improving regeneration. Post-operative electrical stimulation (ES) increases axon regrowth, but practical challenges from the cost of extended operating room time to the risks and pitfalls associated with transcutaneous wire placement have prevented broad clinical adoption. This study presents a possible solution in the form of advanced bioresorbable materials for thin, flexible, wireless implant that provides precisely controlled ES of the injured nerve for a brief time in the immediate post-operative period. Afterward, rapid, complete and safe modes of bioresorption naturally and quickly eliminate all of the constituent materials in their entirety, without the need for surgical extraction. The unusually high rate of bioresorption follows from the use of a unique, bilayer enclosure that combines two distinct formulations of a biocompatible form of polyanhydride as an encapsulating structure, to accelerate the resorption of active components and confine fragments until complete resorption. Results from mouse models of tibial nerve transection with re-anastomosis indicate that this system offers levels of performance and efficacy that match those of conventional wired stimulators, but without the need to extend the operative period or to extract the device hardware.

Targeted Muscle Reinnervation at the Time of Upper-Extremity Amputation for the Treatment of Pain Severity and Symptoms.

PURPOSE: Targeted muscle reinnervation (TMR) is a technique for the management of peripheral nerves in amputation. Phantom limb pain (PLP) and residual limb pain (RLP) trouble many patients after amputation, and TMR has been shown to reduce this pain when performed after the initial amputation. We hypothesize that TMR at the time of amputation may improve pain for patients after major upper-extremity amputation. METHODS: We conducted a retrospective review of patients who underwent major upper-extremity amputation with TMR performed at the time of the index amputation (early TMR). Phantom limb pain and RLP intensity and associated symptoms were assessed using the numeric rating scale (NRS), the Patient-Reported Outcome Measurement Information System (PROMIS) Pain Intensity Short-Form 3a, the Pain Behavior Short-Form 7a, and the Pain Interference Short-Form 8a. The TMR cohort was compared with benchmarked data from a sample of upper-extremity amputees. RESULTS: Sixteen patients underwent early TMR and were compared with 55 benchmark patients. More than half of early TMR patients were without PLP (62%) compared with 24% of controls. Furthermore, half of all patients were free of RLP compared with 36% of controls. The median PROMIS PLP intensity score for the general sample was 47 versus 38 in the early TMR sample. Patients who underwent early TMR reported reduced pain behaviors and interference specific to PLP (50 vs 53 and 41 vs 50, respectively). The PROMIS RLP intensity score was lower in patients with early TMR (36 vs 47). CONCLUSIONS: This study demonstrates that early TMR is a promising strategy for treating pain and improving the quality of life in the upper-extremity amputee. Early TMR may preclude the need for additional surgery and represents an important technique for peripheral nerve surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Targeted Muscle Reinnervation as a Solution for Nerve Pain.

LEARNING OBJECTIVES: After reading this article, the participants should be able to: 1. List current nonsurgical and surgical strategies for addressing postamputation neuroma pain and discuss their limitations. 2. Summarize the indications and rationale for targeted muscle reinnervation. 3. Develop an operative plan for targeted muscle reinnervation in an acute or delayed fashion for upper and lower extremity amputations. 4. Propose a management algorithm for treatment of symptomatic neuromas in an intact limb. 5. Discuss the risk of neuroma development after primary revision digital amputation or secondary surgery for a digital neuroma. 6. Compare and contrast targeted muscle reinnervation to the historical gold standard neuroma treatment of excision and burying the involved nerve in muscle, bone, or vein graft. 7. Interpret and discuss the evidence that targeted muscle reinnervation improves postamputation neuroma and phantom pain when performed either acutely or in a delayed fashion to treat existing pain. SUMMARY: Symptomatic injured nerves resulting from amputations, extremity trauma, or prior surgery are common and can decrease patient quality of life, thus necessitating an effective strategy for management. Targeted muscle reinnervation is a modern surgical strategy for prevention and treatment of neuroma pain that promotes nerve regeneration and healing rather than neuroma formation. Targeted muscle reinnervation involves the transfer of cut peripheral nerves to small motor nerves of adjacent, newly denervated segments of muscle and can be easily performed without specialized equipment. Targeted muscle reinnervation strategies exist for both upper and lower extremity amputations and for symptomatic neuromas of intact limbs. Targeted muscle reinnervation has been shown in a prospective, randomized, controlled trial to result in lower neuroma and phantom pain when compared to the historical gold standard of burying cut nerves in muscle.

Targeted muscle reinnervation at the time of amputation in the management of complex regional pain syndrome of the lower extremity.

BACKGROUND: Complex regional pain syndrome (CRPS) is a chronic, posttraumatic condition defined by severe pain and sensorimotor dysfunction. In cases of severe CRPS, patients request amputation, which may cause phantom limb pain (PLP) and residual limb pain (RLP). Targeted muscle reinnervation (TMR) reduces the risk of PLP and RLP. This report describes the use of TMR at the time of amputation in a series of patients with CRPS. PATIENTS AND METHODS: Four patients (ages 38-71 years) underwent TMR at the time of amputation for CRPS between April 2018 and January 2019. Three patients had a history of trauma and surgery to the affected limb. All patients attempted pharmacologic and interventional treatments for 1-7 years before requesting amputation. Three patients underwent below-knee amputations (BKA) and one had an above-knee amputation (AKA). Target muscles included the soleus, gastrocnemius, and flexor hallucis longus (BKA), and semitendinosus, biceps femoris, and vastus medialis (AKA). Postoperative phantom and residual limb pain symptoms were collected via a telephone survey adapted from the Patient-Reported Outcomes Measurement Information System (PROMIS). RESULTS: There were no complications related to the TMR procedure. Average follow-up time was 12.75 months. Patients reported varied outcomes: two had RLP and PLP, one had RLP only, and one had PLP only. All patients reported successful prosthetic use. CONCLUSION: TMR may be performed at the time of amputation for CRPS. Further study is necessary to determine the effect of TMR on pain, pain medication use, prosthesis use, and other domains of function.

Benchmarking Residual Limb Pain and Phantom Limb Pain in Amputees through a Patient-reported Outcomes Survey.

More than 75% of major limb amputees experience chronic pain; however, data on severity and experience of pain are inconsistent. Without a benchmark using quantitative patient-reported outcomes, it is difficult to critically assess the efficacy of novel treatment strategies. Our primary objective is to report quantitative pain parameters for a large sample of amputees using the validated Patient-reported Outcomes Measurement System (PROMIS). Secondarily, we hypothesize that certain patient factors will be associated with worse pain. METHODS: PROMIS and Numerical Rating Scales for residual limb pain (RLP) and phantom limb pain (PLP) were obtained from a cross-sectional survey of upper and lower extremity amputees recruited throughout North America via amputee clinics and websites. Demographics (gender, age, race, and education) and clinical information (cause, amputation level, and time since amputation) were collected. Regression modeling identified factors associated with worse pain scores (P < 0.05). RESULTS: Seven hundred twenty-seven surveys were analyzed, in which 73.4% reported RLP and 70.4% reported PLP. Median residual PROMIS scores were 46.6 [interquartile range (IQR), 41-52] for RLP Intensity, 56.7 (IQR, 51-61) for RLP Behavior, and 55.9 (IQR, 41-63) for RLP Interference. Similar scores were calculated for PLP parameters: 46.8 (IQR, 41-54) for PLP Intensity, 56.2 (IQR, 50-61) for PLP Behavior, and 54.6 (IQR, 41-62) for PLP Interference. Female sex, lower education, trauma-related amputation, more proximal amputation, and closer to time of amputation increased odds of PLP. Female sex, lower education, and infection/ischemia-related amputation increased odds of RLP. CONCLUSION: This survey-based analysis provides quantitative benchmark data regarding RLP and PLP in amputees with more granularity than has previously been reported.

Cell Phone Application to Monitor Pain and Quality of Life in Neurogenic Pain Patients.

Management of postoperative pain is a challenge for healthcare providers in all surgical fields, especially in the context of the current opioid epidemic. We developed a cell phone application to monitor pain, medication use, and relevant quality of life domains (eg, mood, mobility, return to work, and sleep) in patients with neurogenic pain, including those with limb loss. A literature review was conducted to define application length and design parameters. The final application includes 12 questions for patients with limb loss and 8 for patients with neurogenic pain without limb loss. Pilot testing with 21 participants demonstrates acceptable time to complete the application (mean = 158 seconds, SD = 81 seconds) and usability, based on the mHealth App Usability Questionnaire. We aim for our application to serve as an outcome measure for evaluation of an evolving group of peripheral nerve procedures, including targeted muscle reinnervation. In addition, the application could be adapted for clinical use in patients undergoing these procedures for neurogenic pain and thus serve as a tool to monitor and manage pain medication use.
