The Use of Unlisted Billing Codes for Microsurgical Breast Reconstruction and Implications for Code Consolidation.

BACKGROUND: Private insurers have considered consolidating the billing codes presently available for microvascular breast reconstruction. There is a need to understand how these different codes are currently distributed and used to help inform how coding consolidation may impact patients and providers. METHODS: Using the Massachusetts All-Payer Claims Database between 2016 and 2020, patients who underwent microsurgical breast reconstruction following mastectomy for cancer-related indications were identified. Multivariable logistic regression was used to test whether an S2068 claim was associated with insurance type and median household income by patient ZIP code. The ratio of S2068 to CPT19364 claims for privately insured patients was calculated for providers practicing in each county. Total payments for professional fees were compared between billing codes. RESULTS: There were 272 claims for S2068 and 209 claims for CPT19364. An S2068 claim was associated with age < 45 years (OR: 1.89, 95% CI: 1.11-3.20, p = 0.019), more affluent ZIP codes (OR: 1.11, 95% CI: 1.03-1.19, p = 0.004), and private insurance (OR: 16.13, 95% CI: 7.81-33.33, p < 0.001). Median total payments from private insurers were 101% higher for S2068 than for CPT19364. In all but two counties (Worcester and Hampshire), the S-code was used more frequently than CPT19364 for their privately insured patients. CONCLUSION: Coding practices for microsurgical breast reconstruction lacked uniformity in Massachusetts, and payments differed greatly between S2068 and CPT19364. Patients from more affluent towns were more likely to have S-code claims. Coding consolidation could impact access, as the majority of providers in Massachusetts might need to adapt their practices if the S-code were discontinued.

Impact of Prepectoral vs. Subpectoral Tissue Expander Placement on Post-mastectomy Radiation Therapy Delivery: A Retrospective Cohort Study.

Background: Implant-based reconstruction is the most common method of postmastectomy reconstruction. Many patients require postmastectomy radiation (PMRT). Tissue expanders (TEs), typically inserted as a first stage, have historically been placed subpectorally. More recently, prepectoral reconstruction has gained popularity, but its impact on PMRT is unknown. Prior studies focus on complication rates and aesthetic outcomes. This study examines whether there is a difference in radiation dosimetry among patients undergoing prepectoral versus subpectoral TE reconstruction. Methods: Electronic medical records and radiation plans of 50 patients (25 prepectoral, 25 subpectoral) who underwent mastectomy with immediate TE reconstruction at our institution or affiliate site were reviewed. Pectoralis major muscle and chest wall structures were contoured and mean percentage volumes of these structures receiving less than 95%, 100%, and more than 105% target radiation dose were calculated, as were heart and ipsilateral lung doses. Welch two sample t test, Fisher exact test, and Pearson chi-squared tests were performed. Results: The groups had comparable patient and tumor characteristics and underwent similar ablative and reconstructive procedures and radiation dosimetry. Subpectoral patients had larger mean areas receiving less than 95% target dose ("cold spots"); prepectoral patients had larger mean areas receiving greater than 105% ("hot spots") and 100% target doses. There were no differences in chest wall, heart, and lung doses. Conclusions: Our results demonstrate an increased mean percentage area of pectoralis cold spots with subpectoral reconstruction and increased area of hot spots and 100% dose delivery to the pectoralis in prepectoral patients. Larger studies should analyze long-term effects of prepectoral reconstruction on radiation dosing and recurrence rates.

Excess mortality among non-COVID-19 surgical patients attributable to the exposure of French intensive and intermediate care units to the pandemic.

PURPOSE: The mobilization of most available hospital resources to manage coronavirus disease 2019 (COVID-19) may have affected the safety of care for non-COVID-19 surgical patients due to restricted access to intensive or intermediate care units (ICU/IMCUs). We estimated excess surgical mortality potentially attributable to ICU/IMCUs overwhelmed by COVID-19, and any hospital learning effects between two successive pandemic waves. METHODS: This nationwide observational study included all patients without COVID-19 who underwent surgery in France from 01/01/2019 to 31/12/2020. We determined pandemic exposure of each operated patient based on the daily proportion of COVID-19 patients among all patients treated within the ICU/IMCU beds of the same hospital during his/her stay. Multilevel models, with an embedded triple-difference analysis, estimated standardized in-hospital mortality and compared mortality between years, pandemic exposure groups, and semesters, distinguishing deaths inside or outside the ICU/IMCUs. RESULTS: Of 1,870,515 non-COVID-19 patients admitted for surgery in 655 hospitals, 2% died. Compared to 2019, standardized mortality increased by 1% (95% CI 0.6-1.4%) and 0.4% (0-1%) during the first and second semesters of 2020, among patients operated in hospitals highly exposed to pandemic. Compared to the low-or-no exposure group, this corresponded to a higher risk of death during the first semester (adjusted ratio of odds-ratios 1.56, 95% CI 1.34-1.81) both inside (1.27, 1.02-1.58) and outside the ICU/IMCU (1.98, 1.57-2.5), with a significant learning effect during the second semester compared to the first (0.76, 0.58-0.99). CONCLUSION: Significant excess mortality essentially occurred outside of the ICU/IMCU, suggesting that access of surgical patients to critical care was limited.

Control Charts Usage for Monitoring Performance in Surgery: A Systematic Review.

OBJECTIVES: The control chart is a graphical tool for data interpretation that detects aberrant variations in specific metrics, ideally leading to the identification of special causes that can be resolved. A clear assessment of control chart utilization and its potential impact in surgery is required to justify recommendations for its dissemination. This review aims to describe how performance monitoring using control charts was used over time in surgery. METHODS: A systematic search of PubMed regarding statistical process control in surgery from its inception until December 2019 was performed using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Information extracted from selected publications included study aim and population setting, monitored indicators, control charts methodological parameters, and implementation strategy. RESULTS: One hundred thirteen studies met the selection criteria with a median of 1916 monitored patients. Overall, 57.5% of studies focused on control chart methodology, 24.8% aimed at evaluating performance changes using control charts retrospectively, and 17.7% implemented control charts for continuous quality improvement prospectively. Although there was a great diversity of used indicators and charting tools, the evaluation of patient safety (72.6%) or efficiency (15.9%) metrics based on Shewhart control chart (33.6%) or cumulative sum chart (54.9%) were common. To foster control charts implementation, 14 studies promoted their periodic review, but only three assessed their impact on patient outcomes. CONCLUSIONS: The scientific literature supports the feasibility and utility of control chart to improve patient safety in multiple surgical settings. Additional studies are necessary to reveal the optimal manner in which to implement this affordable tool in surgical practice.

Optimal Timing of Delayed Microvascular Breast Reconstruction after Radiation Therapy.

BACKGROUND: The purpose of this study was to determine the optimal timing of delayed microvascular breast reconstruction after completion of postmastectomy radiation therapy (PMRT). The authors evaluated whether the timing of reconstruction after PMRT completion affects the development of major postoperative complications. We hypothesize that delayed microvascular breast reconstruction can be safely performed within 12 months of PMRT completion. METHODS: A retrospective chart review of microvascular, autologous breast reconstructions at Brigham and Women's Hospital from 2007 to 2019 was performed. Logistic regression analysis and marginal estimation methods were used to estimate the probability of any major complication (flap compromise requiring operative intervention, hematoma formation requiring evacuation, infection requiring readmission, and flap necrosis requiring operative debridement) occurring in 2-month intervals after PMRT. Patients were classified as having undergone reconstruction 0 to 12 months after PMRT (group 1), 12 to 18 months after PMRT (group 2), or 18 to 50 months after PMRT (group 3). RESULTS: A total of 303 patients were identified. All patients received postmastectomy radiation (n = 143 group 1, n = 57 group 2, n = 103 group 3). Mean follow-up time was 71.4 ± 38 months. Patients in group 1 were significantly younger and more likely to have undergone neoadjuvant chemotherapy (p < 0.05). Major complications occurred in 10% of patients. There was no significant difference in the development of major complications between the three groups (p = 0.57). Although not statistically significant, the probability of any major complication peaked 2 to 6 months after PMRT completion. CONCLUSION: There was no significant difference in major complications among patients who underwent delayed, microvascular breast reconstruction within versus beyond 1 year of PMRT completion. These findings suggest that delayed microvascular breast reconstruction can be safely performed beginning 6 months after PMRT completion.

Clinical viability of magnetic bead implants in muscle.

Human movement is accomplished through muscle contraction, yet there does not exist a portable system capable of monitoring muscle length changes in real time. To address this limitation, we previously introduced magnetomicrometry, a minimally-invasive tracking technique comprising two implanted magnetic beads in muscle and a magnetic field sensor array positioned on the body's surface adjacent the implanted beads. The implant system comprises a pair of spherical magnetic beads, each with a first coating of nickel-copper-nickel and an outer coating of Parylene C. In parallel work, we demonstrate submillimeter accuracy of magnetic bead tracking for muscle contractions in an untethered freely-roaming avian model. Here, we address the clinical viability of magnetomicrometry. Using a specialized device to insert magnetic beads into muscle in avian and lagomorph models, we collect data to assess gait metrics, bead migration, and bead biocompatibility. For these animal models, we find no gait differences post-versus pre-implantation, and bead migration towards one another within muscle does not occur for initial bead separation distances greater than 3 cm. Further, using extensive biocompatibility testing, the implants are shown to be non-irritant, non-cytotoxic, non-allergenic, and non-irritating. Our cumulative results lend support for the viability of these magnetic bead implants for implantation in human muscle. We thus anticipate their imminent use in human-machine interfaces, such as in control of prostheses and exoskeletons and in closed-loop neuroprosthetics to aid recovery from neurological disorders.

Coaching for Surgeons: A Scoping Review of the Quantitative Evidence.

To characterize quantitative studies on coaching interventions for professional surgeons to understand how surgical coaching is defined; examine how different coaching programs are designed, implemented, and evaluated; and identify any relevant research gaps. Background: Surgical coaching is gaining attention as an approach that could help surgeons optimize performance and improve overall wellbeing. However, surgical coaching programs and definitions of coaching vary widely between studies. Methods: A systematic literature search of PubMed, Scopus, Web of Science, CENTRAL, clinicaltrials.gov, and WHO ICTRP was conducted according to the PRISMA-ScR framework to identify studies and registered clinical trials written in English. Original quantitative studies on coaching interventions for professional surgeons were included. Characteristics of the coachees, coaching programs, study designs, outcomes, and findings were charted and analyzed. Results: From 2589 references, 8 studies (6 published; 2 registered trials) met inclusion criteria. Published studies targeted technical or nontechnical skills, included 2-26 surgeons as coachees, and used coaches who were surgeons. Two studies demonstrated that surgeons react positively to coaching. Studies showed inconsistent effects on technical/nontechnical skills. Only two studies measured patient adverse events and reported no significant positive impacts. The registered randomized trials targeted surgeons' physiological parameters or wellbeing and used professional coaches. These trials measure surgeon and patient outcomes. Conclusions: There is an emerging interest in coaching programs to improve surgeons' performance by targeting their professional skills and personal factors. However, more randomized trials are needed to evaluate the impact of coaching interventions on patient outcomes and surgeon wellness.

Targeted Nipple Areola Complex Reinnervation: Technical Considerations and Surgical Efficiency in Implant-based Breast Reconstruction.

Background: Despite promising pilot study results, adoption of neurotization of immediate implant-based reconstructions has not occurred. Methods: For surgeons interested in adopting breast reinnervation techniques, we present ways to overcome initial barriers by decreasing operative time and maximizing chances of sensory recovery. Results: We discuss the combined experience at two academic teaching hospitals, where neurotization of both immediate tissue expander cases and direct-to-implant reconstructions are performed through varying mastectomy incisions. Conclusion: Initial barriers can be overcome by shortening operative time and providing an individualized reinnervation approach that aims to increase the chance of meaningful sensation.

Safety of DIEP Flap Reconstruction in Patients with Factor V Leiden: A Retrospective Cohort Study.

Background: Factor V Leiden (FVL) is the most common inherited thrombophilia in White people. Thrombotic complications resulting from free flap breast reconstruction in FVL patients have been studied to a limited degree. We evaluated whether patients heterozygous for a FVL mutation undergoing deep inferior epigastric perforator flap reconstruction had increased risk of micro- or macrovascular thrombotic complications compared with patients without a diagnosed thrombophilia. Methods: We performed a retrospective cohort study of deep inferior epigastric perforator flap reconstructions at Brigham and Women's Hospital (1/2015-12/2020) comparing patients diagnosed as FVL heterozygotes compared with matched controls without a diagnosed thrombophilia. Patients were matched using coarsened exact matching algorithm based on clinical characteristics. The primary outcomes were micro- (return to OR for flap compromise, flap loss) and macrovascular (venous thromboembolism) complications. Results: A total of 506 patients (812 flaps) were included in this study. Eleven patients (17 flaps) were FVL heterozygotes. After matching, 10 patients (16 flaps) with FVL were matched to 55 patients (94 flaps). The return to OR for flap compromise was 0% in the FVL cohort compared with 5% (n = 5/94, 3/94 flaps lost, P = 1.00) in the matched controls (1.9%, n = 15/795 in unmatched controls, 0.6%, n = 5/795 loss rate). There were zero venous thromboembolism events among FVL patients compared with 2% of controls (n = 1/55). Conclusions: FVL heterozygosity did not increase the risk of micro- or macrovascular complications in patients undergoing deep inferior epigastric perforator flap breast reconstruction. This study supports the safety of microvascular reconstruction in this group of patients when appropriate venous thromboembolism prophylaxis is given.

Left Internal Mammary Vein Size and Its Impact on Microsurgical Breast Reconstruction.

The internal mammary vessels are the preferred recipient during free-flap breast reconstruction (FFBR). Previous studies have demonstrated that the left internal mammary vein (IMV) is consistently smaller than the right, but with unclear clinical implications. This study explores the impact of IMV size difference on FFBR complication rates. Methods: Abdominal-based FFBRs were retrospectively reviewed. Venous coupler size was considered a proxy for IMV diameter. Outcomes of three patient cohorts (all, unilateral, and bilateral reconstructions) were analyzed with univariate and multivariate analysis. Results: Our cohort consisted of 582 patients who underwent 874 abdominal-based FFBR, with a similar number of unilateral (n = 290) and bilateral (n = 292), and right (n = 424) and left (n = 450) reconstructions. Mean follow-up was over 4-years. For all reconstructions, the left IMV (2.7 ± 0.4 mm) was smaller than the right (3.0 ± 0.4 mm) (P < 0.0001). Complication rates between left- and right-sided FFBR were similar, but with a trend toward increased fat necrosis on the left (n = 17, 3.8% versus n = 8, 1.9%). Further subgroup analysis showed significantly higher fat necrosis in unilateral left-sided FFBR (n = 12 versus n = 2, P = 0.02), with left-sided FFBR being an independent risk factor for fat necrosis on multivariate analysis. Conclusions: The left-side IMV is significantly smaller than the right IMV. In bilateral reconstructions, the smaller size of the left IMV did not result in a greater risk of complications; however, in unilateral FFBR, fat necrosis was significantly higher on the left side.

The Agonist-antagonist Myoneural Interface.

Scientist and technologist have long sought to advance limb prostheses that connect directly to the peripheral nervous system, enabling a person with amputation to volitionally control synthetic actuators that move, stiffen and power the prosthesis, as well as to experience natural afferent sensations from the prosthesis. Recently, the agonist-antagonist myoneural interface (AMI) was developed, a mechanoneural transduction architecture and neural interface system designed to provide persons with amputation improved muscle-tendon proprioception and neuroprosthetic control. In this paper, we provide an overview of the AMI, including its conceptual framing and pre-clinical science, surgical techniques for its construction, and clinical efficacy related to pain mitigation, phantom limb range of motion, fascicle dynamics, central brain proprioceptive sensorimotor preservation, and prosthetic controllability. Following this broad overview, we end with a discussion of current limitations of the AMI and potential resolutions to such challenges.

The Agonist-Antagonist Myoneural Interface.

The agonist-antagonist myoneural interface is a novel surgical construct and neural interfacing approach designed to augment volitional control of adapted prostheses, preserve proprioception, and prevent limb atrophy in the setting of limb amputation.

The Plastic Surgeon's Role in the COVID-19 Crisis: Regarding Domestic Violence.

Pandemics are associated with increased rates of intimate partner violence (IPV). IPV-related physical abuse is most commonly inflicted through craniofacial assault and upper extremity injury. Plastic surgeons are frequently consulted for recommendations in the management of head-and-neck and hand trauma, thereby are uniquely positioned to encounter patients who have experienced IPV. However, IPV training is not routinely offered in surgical education. We provide a review of the increasing prevalence of IPV during the COVID-19 pandemic and its pertinence to plastic surgery consultation in the emergency room. This article aims to increase providers' confidence in recognizing IPV-suspicious injuries and propose an educational, interactive tool for discussing IPV with patients.

Neural interfacing architecture enables enhanced motor control and residual limb functionality postamputation.

Despite advancements in prosthetic technologies, patients with amputation today suffer great diminution in mobility and quality of life. We have developed a modified below-knee amputation (BKA) procedure that incorporates agonist-antagonist myoneural interfaces (AMIs), which surgically preserve and couple agonist-antagonist muscle pairs for the subtalar and ankle joints. AMIs are designed to restore physiological neuromuscular dynamics, enable bidirectional neural signaling, and offer greater neuroprosthetic controllability compared to traditional amputation techniques. In this prospective, nonrandomized, unmasked study design, 15 subjects with AMI below-knee amputation (AB) were matched with 7 subjects who underwent a traditional below-knee amputation (TB). AB subjects demonstrated significantly greater control of their residual limb musculature, production of more differentiable efferent control signals, and greater precision of movement compared to TB subjects (P < 0.008). This may be due to the presence of greater proprioceptive inputs facilitated by the significantly higher fascicle strains resulting from coordinated muscle excursion in AB subjects (P < 0.05). AB subjects reported significantly greater phantom range of motion postamputation (AB: 12.47 ± 2.41, TB: 10.14 ± 1.45 degrees) when compared to TB subjects (P < 0.05). Furthermore, AB subjects also reported less pain (12.25 ± 5.37) than TB subjects (17.29 ± 10.22) and a significant reduction when compared to their preoperative baseline (P < 0.05). Compared with traditional amputation, the construction of AMIs during amputation confers the benefits of enhanced physiological neuromuscular dynamics, proprioception, and phantom limb perception. Subjects' activation of the AMIs produces more differentiable electromyography (EMG) for myoelectric prosthesis control and demonstrates more positive clinical outcomes.

Reinventing Extremity Amputation in the Era of Functional Limb Restoration.

BACKGROUND: Recent progress in biomechatronics and vascularized composite allotransplantation have occurred in the absence of congruent advancements in the surgical approaches generally utilized for limb amputation. Consideration of these advances, as well as of both novel and time-honored reconstructive surgical techniques, argues for a fundamental reframing of the way in which amputation procedures should be performed. METHODS: We review sentinel developments in external prosthetic limb technology and limb transplantation, in addition to standard and emerging reconstructive surgical techniques relevant to limb modification, and then propose a new paradigm for limb amputation. RESULTS: An approach to limb amputation based on the availability of native tissues is proposed, with the intent of maximizing limb function, limiting neuropathic pain, restoring limb perception/proprioception and mitigating limb atrophy. CONCLUSIONS: We propose a reinvention of the manner in which limb amputations are performed, framed in the context of time-tested reconstructive techniques, as well as novel, state-of-the-art surgical procedures. Implementation of the proposed techniques in the acute setting has the potential to elevate advanced limb replacement strategies to a clinical solution that perhaps exceeds what is possible through traditional surgical approaches to limb salvage. We therefore argue that amputation, performed with the intent of optimizing the residuum for interaction with either a bionic or a transplanted limb, should be viewed not as a surgical failure, but as an alternative form of limb reconstruction.

Effect of monitoring surgical outcomes using control charts to reduce major adverse events in patients: cluster randomised trial.

OBJECTIVE: To determine the effect of introducing prospective monitoring of outcomes using control charts and regular feedback on indicators to surgical teams on major adverse events in patients. DESIGN: National, parallel, cluster randomised trial embedding a difference-in-differences analysis. SETTING: 40 surgical departments of hospitals across France. PARTICIPANTS: 155 362 adults who underwent digestive tract surgery. 20 of the surgical departments were randomised to prospective monitoring of outcomes using control charts with regular feedback on indicators (intervention group) and 20 to usual care only (control group). INTERVENTIONS: Prospective monitoring of outcomes using control charts, provided in sets quarterly, with regular feedback on indicators (intervention hospitals). To facilitate implementation of the programme, study champion partnerships were established at each site, comprising a surgeon and another member of the surgical team (surgeon, anaesthetist, or nurse), and were trained to conduct team meetings, display posters in operating rooms, maintain a logbook, and devise an improvement plan. MAIN OUTCOME MEASURES: The primary outcome was a composite of major adverse events (inpatient death, intensive care stay, reoperation, and severe complications) within 30 days after surgery. Changes in surgical outcomes were compared before and after implementation of the programme between intervention and control hospitals, with adjustment for patient mix and clustering. RESULTS: 75 047 patients were analysed in the intervention hospitals (37 579 before and 37 468 after programme implementation) versus 80 315 in the control hospitals (41 548 and 38 767). After introduction of the control chart, the absolute risk of a major adverse event was reduced by 0.9% (95% confidence interval 0.4% to 1.4%) in intervention compared with control hospitals, corresponding to 114 patients (70 to 280) who needed to receive the intervention to prevent one major adverse event. A significant decrease in major adverse events (adjusted ratio of odds ratios 0.89, 95% confidence interval 0.83 to 0.96), patient death (0.84, 0.71 to 0.99), and intensive care stay (0.85, 0.76 to 0.94) was found in intervention compared with control hospitals. The same trend was observed for reoperation (0.91, 0.82 to 1.00), whereas severe complications remained unchanged (0.96, 0.87 to 1.07). Among the intervention hospitals, the effect size was proportional to the degree of control chart implementation witnessed. Highly compliant hospitals experienced a more important reduction in major adverse events (0.84, 0.77 to 0.92), patient death (0.78, 0.63 to 0.97), intensive care stay (0.76, 0.67 to 0.87), and reoperation (0.84, 0.74 to 0.96). CONCLUSIONS: The implementation of control charts with feedback on indicators to surgical teams was associated with concomitant reductions in major adverse events in patients. Understanding variations in surgical outcomes and how to provide safe surgery is imperative for improvements. TRIAL REGISTRATION: ClinicalTrials.gov NCT02569450.

Content Validity of the LIMB-Q: A Patient-Reported Outcome Instrument for Lower Extremity Trauma Patients.

BACKGROUND: Limb-threatening lower extremity traumatic injuries can be devastating events with a multifaceted impact on patients. Therefore, evaluating patient-reported outcomes (PROs) in addition to traditional surgical outcomes is important. However, currently available instruments are limited as they were not developed specific to lower extremity trauma patients and lack content validity. The LIMB-Q is being developed as a novel PRO instrument to meet this need, with the goal to measure all relevant concepts and issues impacting amputation and limb-salvage patients after limb-threatening lower extremity trauma. METHODS: This is a qualitative interview-based study evaluating content validity for the LIMB-Q. Patients aged 18 years and older who underwent amputation, reconstruction, or amputation after failed reconstruction were recruited using purposeful sampling to maximize variability of participant experiences. Expert opinion was solicited from a variety of clinical providers and qualitative researchers internationally. Preliminary items and scales were modified, added, or removed based on participant and expert feedback after each round of participant interviews and expert opinion. RESULTS: Twelve patients and 43 experts provided feedback in a total of three rounds, with changes to the preliminary instrument made between each round. One scale was dropped after round one, one scale was added after round two, and only minor changes were needed after round three. Modifications, additions and removal of items, instructions, and response options were made after each round using feedback gathered. CONCLUSION: The LIMB-Q was refined and modified to reflect feedback from patients and experts in the field. Content validity for the LIMB-Q was established. Following a large-scale field test, the LIMB-Q will be ready for use in research and clinical care.

All hands on deck: Hand replantation versus transplantation.

OBJECTIVES: Our hands play a remarkable role in our activities of daily living and the make-up of our identities. In the United States, an estimated 41,000 individuals live with upper limb loss. Our expanding experience in limb transplantation-including operative techniques, rehabilitation, and expected outcomes-has often been based on our past experience with replantation. Here, we undertake a systematic review of replantation with transplantation in an attempt to better understand the determinants of outcome for each and to provide a summary of the data to this point. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted PubMed searches from 1964 to 2013 for articles in English. In total, 53 primary and secondary source articles were found to involve surgical repair (either replantation or transplantation) for complete amputations at the wrist and forearm levels. All were read and analyzed. RESULTS: Hand replantations and transplantations were compared with respect to pre-operative considerations, surgical techniques, post-operative considerations and outcomes, including motor, sensation, cosmesis, patient satisfaction/quality of life, adverse events/side effects, financial costs, and overall function. While comparison of data is limited by heterogeneity, these data support our belief that good outcomes depend on patient expectations and commitment. CONCLUSION: When possible, hand replantation remains the primary option after acute amputation. However, when replantation fails or is not possible, hand transplantation appears to provide at least equal outcomes. Patient commitment, realistic expectations, and physician competence must coincide to achieve the best possible outcomes for both hand replantation and transplantation.

Identifying Factors Most Important to Lower Extremity Trauma Patients: Key Concepts from the Development of a Patient-Reported Outcome Instrument for Lower Extremity Trauma, The LIMB-Q.

BACKGROUND: Severe lower extremity injuries are challenging to treat. The aspects of limb salvage and amputation most important to patients are not well-defined. This study's aim is to develop a conceptual framework for a patient-reported outcome instrument for lower extremity trauma patients, by defining issues and concepts most important to this patient population. METHODS: This is an interpretative description of transcripts collected from semistructured qualitative interviews at a single institution. High-energy lower extremity trauma patients were recruited by means of purposeful sampling to maximize variability. Thirty-three participant interviews were needed to reach content saturation. These participants were aged 19 to 79 years; 21 were men (63.6 percent); participation was after reconstruction [n= 15 (45.5 percent)], after amputation [n = 11 (33.3 percent)], or after amputation after failed reconstruction [n = 7 (21.2 percent)]. Interviews were recorded, transcribed, and coded line-by-line. Concepts were labeled with major and minor themes and refined through a process of constant comparison. Analysis led to the development of a conceptual framework and item pool to inform the development of a patient-reported outcome measure. RESULTS: In total, 2430 unique codes were identified and used to generate the conceptual framework covering 10 major themes: appearance, environment, finances, physical, process of care, prosthesis, psychological, sexual, social, and treatment. CONCLUSIONS: This study establishes a comprehensive set of concepts, identifying what is most important to severe lower extremity trauma patients. These findings can be used to inform and focus research and clinical care, and provides the framework to develop a lower extremity trauma-specific patient-reported outcome instrument: the LIMB-Q.
