Segmental infralesional pathological spontaneous activity in subacute traumatic spinal cord injury.

INTRODUCTION/AIMS: There is a dearth of knowledge regarding the status of infralesional lower motor neurons (LMNs) in individuals with traumatic cervical spinal cord injury (SCI), yet there is a growing need to understand how the spinal lesion impacts LMNs caudal to the lesion epicenter, especially in the context of nerve transfer surgery to restore several key upper limb functions. Our objective was to determine the frequency of pathological spontaneous activity (PSA) at, and below, the level of spinal injury, to gain an understanding of LMN health below the spinal lesion. METHODS: Ninety-one limbs in 57 individuals (53 males, mean age = 44.4 ± 16.9 years, mean duration from injury = 3.4 ± 1.4 months, 32 with motor complete injuries), were analyzed. Analysis was stratified by injury level as (1) C4 and above, (2) C5, and (3) C6-7. Needle electromyography was performed on representative muscles innervated by the C5-6, C6-7, C7-8, and C8-T1 nerve roots. PSA was dichotomized as present or absent. Data were pooled for the most caudal infralesional segment (C8-T1). RESULTS: A high frequency of PSA was seen in all infralesional segments. The pooled frequency of PSA for all injury levels at C8-T1 was 68.7% of the limbs tested. There was also evidence of PSA at the rostral border of the neurological level of injury, with 58.3% of C5-6 muscles in those with C5-level injuries. DISCUSSION: These data support a high prevalence of infralesional LMN abnormalities following SCI, which has implications to nerve transfer candidacy, timing of the intervention, and donor nerve options.

Variable effects of exposure to ionic silver in wound-associated bacterial pathogens.

Silver compounds are used in wound dressings to reduce bioburden. Where infection is not rapidly resolved, bacteria may be exposed to sub-therapeutic concentrations of antimicrobials over prolonged periods of time. In this study, a panel of chronic wound bacteria, Pseudomonas aeruginosa (two strains), Staphylococcus aureus, and Escherichia coli, were exposed to silver nitrate on agar. Phenotypic characterization was achieved using broth microdilution sensitivity testing, a crystal violet biofilm assay, and a wax moth pathogenesis model. Repeated exposure to ionic silver did not result in planktonic phenotypic silver resistance in any of the test panels, although S. aureus demonstrated reversible increases in minimum bactericidal concentration. An ulcer-derived P. aeruginosa exhibited marked reductions in biofilm eradication concentration as well as significantly increased biofilm formation and wax moth killing when compared to the same progenitor. These changes were reversible, trending towards baseline measurements following 10 passages on silver-free media. Changes in virulence and biofilm formation in the other test bacteria were generally limited. In summary, phenotypic adaptation following exposure to ionic silver was manifested other than through changes in planktonic susceptibility. Significant changes in pseudomonas biofilm formation and sensitivity could have implications for wound care regimes and therefore warrant further investigation.

Implications of the COVID-19 Pandemic on Immediate Breast Reconstruction Access.

AIMS: As a result of COVID-19, there have been restrictions on surgical interventions across Canada. Immediate breast reconstruction (IBR), while an essential component of cancer care, is classified as elective surgery and therefore has been restricted in access over the course of the pandemic. The purpose of this study was to compare wait times for breast cancer patients undergoing surgical intervention for IBR before and since the COVID-19 pandemic. METHODS: This was a retrospective cross-sectional study of consecutive patients who underwent IBR between July 2018 and October 2021 by 5 plastic surgeons at a single Canadian health center. Wait times to consultation and surgical intervention between pre- and post-COVID cohorts were analyzed. RESULTS: A total of 161 patients met inclusion criteria. For ablative surgery, there was no difference in wait times to surgical oncology consultation (14.0 ± 12.3 vs 14.0 ± 11.0 days, P = 0.991) and surgical intervention with IBR (41.0 ± 49.8 vs 35.0 ± 58.0 days, P = 0.621) between the pre- and post-COVID cohorts. For breast reconstruction, while time to consultation with plastic surgery (12.5 ± 14.8 vs 11.0 ± 12.8 days, P = 0.775) remained unchanged, usage of autologous techniques was reduced [n = 13 (16%) vs n = 2 (2%), P = 0.006], and time to second-stage alloplastic reconstruction increased (230 ± 102 vs 325 ± 224 days, P = 0.044) post-COVID. CONCLUSIONS: Swift adoption of evidence driven protocols has resulted in comparable wait times for breast cancer ablative procedures. However, utilization of autologous techniques and wait times to second-stage reconstructions have increased.

Comparing Flap Advancement and Wound Coverage of Anterograde Homodigital Neurovascular Island Flap Designs: A Cadaveric Model.

PURPOSE: Anterograde homodigital neurovascular island flaps are a reconstructive option for volar fingertip injuries and confer the advantage of preserving fingertip sensation after surgery. However, the amount of flap advancement and wound coverage provided by stepwise and triangular flap designs remains unknown. This study sought to investigate how incremental proximal dissection of the pedicle influences flap advancement and whether advancement and/or coverage differ between the triangular and stepwise flap designs using 22 paired cadaveric digits. METHODS: Flap advancement and wound coverage were evaluated in a pairwise design such that each pair of digits received 1 stepwise flap and 1 triangular flap. After creating a standardized injury to the volar fingertip, pedicled flaps were dissected from the middle phalanx and advanced distally under consistent tension. Advancement was measured for each 5 mm of proximal mobilization of the pedicle to a maximum of 30 mm. RESULTS: On average, 2.6 ± 0.2 mm of flap advancement could be achieved for every 10 mm of pedicle mobilization. With 30 mm of proximal mobilization of the pedicle, 11.8 ± 2.8 mm of advancement and 57.2% ± 16.1% of wound coverage could be expected. There were no significant differences between the flap designs. CONCLUSIONS: The stepwise and triangular anterograde homodigital neurovascular island flaps offer comparable and consistent reconstructive outcomes for volar fingertip injuries. CLINICAL RELEVANCE: The findings in this study suggest that the choice of flap design need not be influenced by the considerations of advancement or coverage; rather, surgeon preference or technical differences between the 2 flap designs may be of more importance.

Management of patients requiring reconstructive breast surgery during the COVID-19 pandemic: recommendations from the BC Regional Breast Reconstruction Network.

Summary: The COVID-19 pandemic has caused unprecedented challenges in health care, threatening access and delivery of medical services across all sectors. Patients with breast cancer desiring breast reconstruction require timely interdisciplinary care; resource limitations threaten access to this elective reconstructive element of cancer care. An expert panel was convened to identify challenges, recommend preliminary solutions, and identify important future directions in anticipation of prolonged restrictions. This paper presents consensus recommendations for care of breast cancer reconstruction patients during the pandemic based on expert opinion from the BC Breast Reconstruction Network.

Postoperative management and rehabilitation after the supercharged end-to-side anterior interosseous nerve to ulnar motor nerve transfer: A report of 3 cases.

INTRODUCTION: Compressive ulnar neuropathy at the elbow is the second most common compressive neuropathy. Nerve transfers are used for severe ulnar neuropathies as a means of facilitating recovery. Hand therapy and rehabilitation after nerve transfers have not been extensively explored. PURPOSE OF THE STUDY: The aim of this repeated case study was to describe the responses, functional outcome, and neuromuscular health of three participants after the supercharged end-to-side (SETS) anterior interosseous nerve (AIN) to ulnar motor nerve transfer do describe the hand therapy and recovery of 3 cases reflecting different recovery potential mediators, trajectories, and outcomes. STUDY DESIGN: Repeated case study. METHODS: Three participants of similar age (76-80 years) that had severe ulnar neuropathy who underwent surgical treatment including a SETS AIN to ulnar motor nerve surgery were purposively selected from an ongoing clinical trial, based on their response to the surgical and the rehabilitation intervention (large, moderate, and small improvements). Clinical evaluations included measuring range of motion, strength testing, and clinical tests (ie, Egawa's sign) and, subjective assessment of rehabilitation adherence., Quick Disability of Arm, Shoulder and Hand and decomposition-based quantitative electromyography were performed at >23 months to evaluate patients. RESULTS: All the three participants completed the surgical and hand therapy interventions, demonstrating a variable course of recovery and functional outcomes. The Quick Disability of Arm, Shoulder and Hand scores (>23 months) for participants A, B, and C were 68, 30, and 18, respectively. The person with the least improvement had idiopathic Parkinson's disease, dyslipidemia, history of depression, and gout. Comparison across cases suggested that the comorbidities, longer time from neuropathy to the surgical intervention, and psychosocial barriers to exercise and rehabilitation adherence influenced the recovery process. The participants with the best outcomes demonstrated improvements in his lower motor neurons or motor unit counts (109 and 18 motor units in the abductor digiti minimi (ADM) and first dorsal interosseous, respectively) and motor unit stability (39.5% and 37.6% near-fiber jiggle in the ADM and first dorsal interosseous, respectively). The participant with moderate response to the interventions had a motor unit count of 93 for the ADM muscle. We were unable to determine motor unit counts and measurements from the participant with the poorest outcomes due to his physical limitations. CONCLUSIONS: SETS AIN to ulnar motor nerve followed by multimodal hand therapy provides measurable improvements in neurophysiology and function, although engagement in hand therapy and outcomes appear to be mediated by comorbid physical and psychosocial health.

Trends in immediate breast reconstruction and radiation after mastectomy: A population study.

In the last decade, there has been an increase in women undergoing immediate breast reconstruction (IBR) at the time of mastectomy. Recent literature suggests a shift in practice: Surgeons are becoming more comfortable with IBR in the setting of possible postoperative adjuvant radiotherapy, despite the known complications. This study sought to investigate, at a population level, the patient and surgeon characteristics associated with the use of IBR and which of these factors were predictive of adjuvant radiotherapy. This retrospective population-based cohort study included all adult women who underwent mastectomy in the province of Ontario from 2007 to 2014. The Canadian Institute for Health Information (CIHI) administrative data base was used to generate patient demographic and clinical data. The Ontario Health Insurance Plan (OHIP) data base was used to elicit surgeon characteristics including clinical experience and volume of practice dedicated to breast surgery. Outcome variables included reconstruction concurrent with mastectomy, alloplastic vs autologous reconstruction, and use of radiation. A total of 25 861 patients underwent mastectomy and 2972 had IBR (11.5%). The rate of IBR after mastectomy increased over time from 7.2% in 2007 to 17.2% in 2014 (P < .001). There was also an increase in the proportion of patients with IBR who received radiation over the time period, from 19.4% in 2007 to 28.2% in 2014 (P = .003). In the first regression analysis, IBR was associated with younger patient age, residing in closer proximity to cancer clinics, absence of malignant breast disease (ie, prophylactic mastectomy), having a younger surgeon performing the mastectomy, and receiving care at a teaching hospital. A second analysis showed that patient variables predictive of radiation after IBR were a younger age and a more advanced cancer stage and no variables specific to surgeon or institution were predictive of radiation in patients with IBR. A significant increase in the rate of IBR as well as the use of radiation occurred over the 7-year study period. Multiple patient and surgeon factors were associated with IBR. Variables associated with radiation in IBR were harder to predict. Given the increase in the use of radiation in IBR, further research is needed to look at long-term outcomes in these patients at the population level.

Treatment of Cervical Spondylotic Amyotrophy With Nerve Transfers.

Cervical spondylotic amyotrophy is characterized by severe, proximal upper extremity weakness including an inability to abduct the shoulder and flex the elbow. Treatment using both medical and surgical decompression approaches has produced variable results. This paper reports the use of nerve transfers (spinal accessory to suprascapular, flexor carpi ulnaris fascicle of ulnar to biceps motor branch, radial nerve branch to triceps to axillary) to restore shoulder and elbow function in a case of unilateral cervical spondylotic amyotrophy involving C5 and C6 myotomes. Evidence of regeneration was observed on electromyography as well as clinically at 5 months postoperatively. At 3 years after surgery, recovery of elbow flexion and shoulder abduction was Medical Research Council grade 4/5 with improved external rotation and considerably improved patient-rated Disabilities of the Arm, Shoulder and Hand scores. We propose that nerve transfers be considered along with other reconstruction modalities in the treatment of cervical spondylotic amyotrophy.

Nerve transfers and neurotization in peripheral nerve injury, from surgery to rehabilitation.

Peripheral nerve injury (PNI) and recent advances in nerve reconstruction (such as neurotization with nerve transfers) have improved outcomes for patients suffering peripheral nerve trauma. The purpose of this paper is to bridge the gap between the electromyographer/clinical neurophysiologist and the peripheral nerve surgeon. Whereas the preceding literature focuses on either the basic science behind nerve injury and reconstruction, or the surgical options and algorithms, this paper demonstrates how electromyography is not just a 'decision tool' when deciding whether to operate but is also essential to all phases of PNI management including surgery and rehabilitation. The recent advances in the reconstruction and rehabilitation of PNI is demonstrated using case examples to assist the electromyographer to understand modern surgical techniques and the unique demands they ask from electrodiagnostic testing.

Incidence and Type of Errors in Microsurgical Technique in Surgical Trainees.

Background The purpose of our study was first to identify microsurgical errors and their incidence. Identifying these common errors and the theoretical approach to prevent or repair them may provide benefit to trainees in the laboratory setting and, ultimately, in the clinical setting. Methods Using a rat femoral artery anastomoses model for resident microsurgical training, direct staff observation with real-time feedback and error identification was employed. Types of microsurgical errors were recorded and instructor feedback relayed to five resident participants. Results Errors were cataloged into five main categories: insufficient approximation (26.1%), vessel backwall (21.7%), incomplete bites (19.6%), tissue tear (19.6%), and irregular widths (13.0%). Further subdivision of the incomplete bite error based on vessel layer violated was performed. Representative figures were created outlining these errors. Conclusions We present common microsurgical errors in trainees and a training model with synchronous feedback. Visual images were designed outlining these errors as an adjunct for teaching.

Prevalence and Severity of Chronic Pain in Patients Receiving Mastectomy with Alloplastic Immediate Breast Reconstruction: A Survey Study.

Introduction: Breast cancer is the most frequently diagnosed cancer worldwide. For those undergoing mastectomy, the choice of alloplastic immediate breast reconstruction (IBR) is increasingly favored. Post-operative chronic pain is an important consideration in this decision, but there is a paucity of data for those undergoing alloplastic IBR. We sought to examine the prevalence, severity, and risk factors for the development of chronic pain in this cohort using validated patient-reported outcome measures. Methods: A cross-sectional survey study was conducted among patients receiving mastectomy with alloplastic IBR. Participants completed 3 surveys querying chronic pain, specifically the Breast Cancer Pain Questionnaire (BCPQ), Brief Pain Inventory (BPI), and BREAST-Q. Participant medical records were reviewed for demographic and surgical variables. Results: A total of 118 patients participated in the study-a response rate of 33.6%. Chronic pain prevalence was high (52.5%), and only 29.0% of these patients had consulted a physician regarding their pain. Among those reporting chronic pain (n = 62), the median severity of pain was 3.1 on an 11-point scale. Chronic pain was associated with radiation (p = .018), bilateral reconstruction (p = .05), worse emotional health (p = .0003), less self (p = .022), and sexual confidence (p = .044). Inter-tool reliability was high, with no significant difference in responses between the 3 surveys. Conclusion: In this cohort, chronic pain is supported as a significant concern among patients who have undergone mastectomy with alloplastic IBR. Given the burden of chronic pain, there is an opportunity to intervene with preventative measures and support for its management.

Introduction: Le cancer du sein est le cancer le plus souvent diagnostiqué dans le monde. L'option de reconstruction mammaire immédiate (RMI) alloplastique est de plus en plus souvent choisie par les patientes subissant une mastectomie. La douleur chronique postopératoire est un important facteur à prendre en compte dans cette décision, mais nous ne disposons que peu de données pour les patientes ayant une RMI alloplastique. Nous avons cherché à étudier la prévalence, la sévérité et les facteurs de risque de survenue d'une douleur chronique dans cette population de patients au moyen de mesures validées de déclaration des résultats. Méthodes: Une enquête transversale a été réalisée parmi les patientes ayant bénéficié d'une RMI alloplastique. Les participants ont répondu à trois enquêtes portant sur la douleur chronique (plus spécifiquement le questionnaire sur la douleur dans le cancer du sein [BCPQ], le Questionnaire court sur la douleur [BPI ou Brief Pain Inventory] et le BREAST-Q). Les dossiers médicaux des participantes ont été examinés à la recherche des variables démographiques et chirurgicales. Résultats: Un total de 118 patientes a participé à l'étude, soit un taux de réponse de 33.6%. La prévalence de la douleur chronique était élevée (52.5%) et seulement 29.0% de ces patientes avaient consulté un médecin à propos de cette douleur. Parmi les participantes signalant une douleur chronique (n = 62), la sévérité médiane de la douleur était de 3,1 sur une échelle de 11 points. La douleur chronique a été associée à la radiothérapie (p = .018), à une reconstruction bilatérale (p = .05), à une aggravation de la santé émotionnelle (p = .0003), à une moindre confiance en soi (p = .022) et sur le plan de la sexualité (p = .044), La fiabilité inter-outils a été élevée, sans différence significative entre réponses dans les trois enquêtes. Conclusion: Il est confirmé que, dans cette cohorte, la douleur chronique est une préoccupation importante chez les patientes ayant subi une mastectomie avec RMI alloplastique. Considérant le fardeau que représente la douleur chronique, il y a une opportunité d'intervention en utilisant des mesures préventives et en apportant un soutien pour sa gestion.

Anti-biofilm effects and healing promotion by silver oxynitrate-based dressings.

Microbial growth within a wound often manifests as biofilms, which can prevent healing and is difficult to eradicate. Novel silver dressings claim to combat wound infection, but anti-biofilm efficacy and effects on healing independent of infection are often unclear. Using in vitro and in vivo S. aureus and P. aeruginosa biofilm models, we report the efficacy of a dressing which produces Ag1+ ions; an Ag1+ dressing containing ethylenediaminetetraacetic acid and benzethonium chloride (Ag1+/EDTA/BC), and a dressing containing silver oxynitrate (Ag Oxysalts) which produces Ag1+, Ag2+ and Ag3+ ions, against wound biofilms, and their effects on healing. Ag1+ dressings had minimal effect on in vitro and murine (C57BL/6j) wound biofilms. In contrast, Ag Oxysalts and Ag1+/EDTA/BC dressings significantly reduced viable bacteria within in vitro biofilms and demonstrated a visible reduction in bacteria and EPS components within murine wound biofilms. The dressings had different effects on the healing of biofilm-infected and uninfected wounds, with Ag Oxysalts dressings having a greater beneficial effect on re-epithelialisation, wound size and inflammation than the control treatment and the other silver dressings. The different physicochemical properties of the silver dressings result in varied effects on wound biofilms and healing which should be considered when selecting dressings to treat biofilm-infected wounds.

Modulation of Biofilm Formation and Permeability in Streptococcus mutans during Exposure To Zinc Acetate.

The penetration of biofilms by antimicrobials is a potential limiting factor in biofilm control. This is relevant to oral health, as compounds that are used to control microbial growth and activities could also affect the permeability of dental plaque biofilm with secondary effects on biofilm tolerance. We investigated the effects of zinc salts on the permeability of Streptococcus mutans biofilms. Biofilms were grown with low concentrations of zinc acetate (ZA), and a transwell transportation assay was applied to test biofilm permeability in an apical-basolateral direction. Crystal violet assays and total viable counts were used to quantify the biofilm formation and viability, respectively, and short time frame diffusion rates within microcolonies were determined using spatial intensity distribution analysis (SpIDA). While the diffusion rates within biofilm microcolonies were not significantly altered, exposure to ZA significantly increased the overall permeability of S. mutans biofilms (P < 0.05) through decreased biofilm formation, particularly at concentrations above 0.3 mg/mL. Transport was significantly lower through biofilms grown in high sucrose conditions. IMPORTANCE Zinc salts are added to dentifrices to improve oral hygiene through the control of dental plaque. We describe a method for determining biofilm permeability and show a moderate inhibitory effect of zinc acetate on biofilm formation, and that this inhibitory effect is associated with increases in overall biofilm permeability.

Evaluation of muscle strength following peripheral nerve surgery: A scoping review.

Peripheral nerve injury (PNI) can result in devastating loss of function, often with poor long-term prognosis. Increased use of peripheral nerve surgical techniques (eg, nerve transfer, nerve grafting, and nerve repair) has resulted in improved muscle strength and other functional outcomes in patients with PNI. Muscle strength has largely been evaluated with the British Medical Research Council (MRC) scale. MRC is convenient to use in clinical settings, but more robust measures of muscle function are necessary to fully elucidate patient recovery. This scoping review aims to examine alternative instruments used to assess muscle function in studies of peripheral nerve surgery for PNI of the upper and lower limbs. A scoping review was conducted using Ovid MEDLINE, CINAHL, EMBASE, and PubMed databases in May and December of 2020, yielding a total of 20 studies pertaining to the review question. Studies pertaining to handheld dynamometry, grip and pinch dynamometry, Rotterdam Intrinsic Hand Myometers, isokinetic dynamometry, ultrasonography, and electromyography were reviewed. We provide a synopsis of each method and current clinical applications and discuss potential benefits, disadvantages, and areas of future research.

Rehabilitation Following Nerve Transfer Surgery.

Nerve transfer surgery is an important new addition to the treatment paradigm following nerve trauma. The following rehabilitation plan has been developed over the past 15 years, in an interdisciplinary, tertiary peripheral nerve program at the "Roth|McFarlane Hand and Upper Limb Centre." This center evaluates more than 400 patients with complex nerve injuries annually and has been routinely using nerve transfers since 2005. The described rehabilitation program includes input from patients, therapists, physiatrists, and surgeons and has evolved based on experience and updated science. The plan is comprised of phases which are practical, reproducible and will serve as a framework to allow other peripheral nerve programs to adapt and improve the "Roth|McFarlane Hand and Upper Limb Centre" paradigm to enhance patient outcomes.

A systematic review and meta-analysis of patient-reported outcomes following nerve transfer surgery for brachial plexus injury.

OBJECTIVE: The purpose of this systematic review and meta-analysis was to determine the effect of nerve transfer surgery for brachial plexus injury (BPI) on patient-reported outcomes. LITERATURE SURVEY: MEDLINE, EMBASE, and CINAHL were searched and screened in duplicate for relevant studies on September 25, 2019 and repeated June 24, 2020. METHODOLOGY: The patient population included male and female patients who received nerve transfer surgery for BPI. Further inclusion criteria were: (1) all levels of evidence; (2) published in English; (3) conducted in humans; and (4) report of patient-reported outcome. Two reviewers independently abstracted data regarding injury type, surgical technique, surgical timing, follow-up duration, strength, and patient-reported outcome measures. Quality was assessed in duplicate using the Methodological Index for Non-Randomized Studies criteria. SYNTHESIS: Twenty-one studies involving 464 participants were included in analyses. The mean age ± SD was 32.4 ± 1.8 (range: 5-77) and 89.2% of included participants were male. The mean time to surgery was 5.6 ± 0.6 months and the mean follow-up time was 48.1 ± 8.4 months. The most used patient-reported outcome was the Disabilities of Arm, Shoulder and Hand (DASH), where scores variably improved postoperatively, although the degree of disability remained high. Return to work was reported in five studies, with 66.0% of participants returning to work. Patient satisfaction was assessed in four studies with an overall satisfaction proportion of 64.0%. Pain was assessed in 12 studies using various measures. In studies reporting pain intensity postoperatively, 29.3% of patients were "pain-free" or had "no pain." CONCLUSIONS: Patient-reported outcomes following nerve transfer for BPI are infrequently reported in the literature. Although patient-reported outcomes demonstrate variable postoperative improvement, there is evidence of ongoing limitations and postoperative DASH scores report a high degree of ongoing disability. Future studies with greater reporting as well as validation of patient-reported outcomes within BPI are warranted.

Surgical Management of Delayed Brachial Plexopathy After Clavicle Nonunion.

SUMMARY: Brachial plexopathy after conservative therapy or surgical treatment of clavicular fractures is an uncommon, yet serious complication that is associated with compression of the brachial plexus or the subclavian artery and vein because they traverse through the thoracic outlet. Surgical decompression of the brachial plexus is the recommended treatment if this condition is to occur. Although there are multiple reports of these cases in the literature, at present, there are no clear guidelines for their management. We are highlighting an institutional management algorithm, illustrated by a small retrospective case series, that uses a multidisciplinary approach in an effort to minimize complications associated with the management of clavicle nonunion.

Canadian Expert Opinion on Breast Reconstruction Access: Strategies to Optimize Care during COVID-19.

BACKGROUND: Breast reconstructive services are medically necessary, time-sensitive procedures with meaningful health-related quality of life benefits for breast cancer survivors. The COVID-19 global pandemic has resulted in unprecedented restrictions in surgical access, including access to breast reconstructive services. A national approach is needed to guide the strategic use of resources during times of fluctuating restrictions on surgical access due to COVID-19 demands on hospital capacity. METHODS: A national team of experts were convened for critical review of healthcare needs and development of recommendations and strategies for patients seeking breast reconstruction during the pandemic. Following critical review of literature, expert discussion by teleconference meetings, and evidenced-based consensus, best practice recommendations were developed to guide national provision of breast reconstructive services. RESULTS: Recommendations include strategic use of multidisciplinary teams for patient selection and triage with centralized coordinated use of alternate treatment plans during times of resource restrictions. With shared decision-making, patient-centered shifting and consolidation of resources facilitate efficient allocation. Targeted application of perioperative management strategies and surgical treatment plans maximize the provision of breast reconstructive services. CONCLUSIONS: A unified national approach to strategically reorganize healthcare delivery is feasible to uphold standards of patient-centered care for patients interested in breast reconstruction.
