The Learning Curves of Adelaide- and Gan-Modified Lim-Tsai Flexor Tendon Repair Techniques.

PURPOSE: Surgical performance that improves with experience is often depicted as representing a "learning curve." Although numerous studies examine the tensile properties of various flexor tendon repairs, few compare the associated learning curves. This study aims to address this gap by comparing the learning curves of Adelaide- and Gan-modified Lim-Tsai repairs. Emphasizing the difference in learning curves is crucial because it highlights the tension between achieving biomechanically superior repairs, which may be challenging to many surgeons, and opting for possibly incrementally less strong but more feasible techniques. METHODS: We organized a workshop attended by 20 medical students whose experience in surgery was limited to a few suturing exercises. Each participant repaired five porcine tendons in situ either with Adelaide- or Gan-modified Lim-Tsai, followed by a peripheral suture. We tested all tendons with linear static testing to measure ultimate and yield loads. In addition, repair times were recorded for each repair. We used a linear mixed model to compare learning between the techniques. RESULTS: Ultimate loads increased with experience and were higher in Adelaide technique during the first two repairs, compared with Gan-modified Lim-Tsai (80 N vs 63 N and 79 N vs 66 N, respectively). Yield loads also increased with experience but did not differ between the repair techniques at any time point. Mean repair times decreased from 44 to 28 minutes and from 46 to 25 minutes with Adelaide- and Gan-modified Lim-Tsai repairs, respectively. CONCLUSIONS: The Adelaide core suture had a higher initial ultimate load capacity despite fewer suture strands, possibly indicating better tension consistency. The ultimate load of the Gan-modified Lim-Tsai repair increased between the first and fifth repair, and repeats were needed to achieve comparable results with the Adelaide repair. CLINICAL RELEVANCE: The results of this study suggest that both repair methods are suitable for novice surgeons, but Adelaide tends to result in higher strength from the first repair. Generalizability to other repairs should be made with caution.

Revision Surgery Following Primary Reconstruction for Hand Syndactyly.

PURPOSE: Web creep and scar contracture are established complications of syndactyly reconstruction; however, few reports characterize risk factors for revision surgery. The purpose of this investigation was to examine the rate and risk factors of reoperation for congenital hand syndactyly. METHODS: Patients undergoing syndactyly reconstruction from 2007 to 2021 at a single children's hospital were reviewed. Cases with less than 1 year of follow-up were excluded. Demographic, surgical, and outcomes data were recorded by each web space to account for mixed treatments. RESULTS: In total, 514 web spaces in 231 children were reviewed with a mean follow-up of 6.0 years after primary reconstruction; 66 (12.8%) web spaces in 51 (22.1%) children underwent revision. The most common procedures were web space deepening due to web creep (57.9% of cases) and digital scar contracture release (45.6%); these were augmented in a minority (17.5%) of cases by other aesthetic/functional procedures. Revisions occurred at a median of 1.7 years after primary reconstruction. First web spaces (thumb-index finger) were most frequently reoperated (33.3%). On multivariable analysis, first web space involvement, complete syndactyly, and complications after the primary reconstruction significantly increased odds of revision. Age at primary reconstruction was not a significant predictor. Following revision, 10.5% of cases had recurrent web creep, and 14.0% had recurrent scar contracture. Eight (1.6%) web spaces in seven (3.0%) children required multiple revisions. CONCLUSIONS: Approximately 13% of syndactyly reconstructions (22% of patients) require reoperation. Most revisions occur within 4 years of primary reconstruction. Complete syndactyly, complications after the primary reconstruction, and first web space involvement increase the risk of revision; age at primary reconstruction is not a risk factor. Revision outcomes mirror the index procedure, with 10% to 14% of revised web spaces experiencing recurrent web creep or contracture. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Prevalence and Practice Characteristics of Advanced Practice Providers in Upper-Extremity Surgery, 2013-2021.

PURPOSE: This study evaluated the prevalence, characteristics, and reimbursement of advanced practice providers, including nurse practitioners and physician assistants, who provide care related to the diagnosis and treatment of diseases and conditions of the hand, wrist, and upper extremities in the United States from 2013 to 2021. METHODS: Our analysis was a retrospective cohort study evaluating the diagnostic, procedural, and therapeutic services provided by advanced practice providers from 2013 to 2021 using the Medicare Provider Utilization and Payment Data Public Use Files from the Centers for Medicare and Medicare Services. The reported provider type and billing codes were used to identify health care professionals providing upper-extremity care such as ordering radiographs, applying casts and splints, and performing procedures on the hand, wrist, or other anatomic regions of the upper extremity. Trends over the study period and available data about services provided were analyzed. RESULTS: From 2013 to 2021, providers of upper-extremity care included 19,525 (64.7%) doctor of medicine or doctor of osteopathic medicine upper-extremity surgeons, 7,612 (25.2%) physician assistants, and 3,042 (10.1%) nurse practitioners. The nonsurgeon providers were more likely to be women and provide care in micropolitan areas with less than 50,000 people compared with upper-extremity surgeons. Overall, the number of advanced practice providers who billed for upper-extremity care increased by 170.9% from 1,965 in 2013 to 5,324 in 2021. Based on these trends, the growth of APPs providing upper-extremity care is expected to continue. CONCLUSIONS: There is a growing prevalence of advanced practice providers in upper-extremity care, and this trend is expected to continue. CLINICAL RELEVANCE: With a growing need for upper-extremity care and predicted shortages in the surgeon workforce, the scope of practice and integration of advanced practice providers merits further discussion and evaluation.

Prevalence and Effect of Cannabinoids in Pain Management for Hand Pathologies.

BACKGROUND: Cannabinoids are a diverse group of compounds under investigation for various medical purposes, including analgesia. Given the evolving landscape of cannabinoid use, we aimed to analyze their prevalence and effect in pain management among urban orthopedic hand patients. METHODS: An electronic survey was administered to 122 new patients presenting to the orthopedic hand clinic of a major urban academic hospital. Demographic data, numerical rating scale pain scores, cannabinoid usage, and other concomitant pain regimens were recorded. RESULTS: Approximately half of the new patients were dissatisfied with current pain management for their hand pathology. Prescription (Rx) and over-the-counter (OTC) pain medications were used by 58% (71/122) of patients, while cannabinoids were used by 15% (18/122) of patients. Compared with pre-usage pain scores, both cannabinoids and Rx/OTC medications induced significant reductions in pain associated with patients' hand pathologies (Cannabinoid: Δ4.4, P = .002; Rx/OTC: Δ3.0, P < .001). Cannabinoids induced a larger analgesic effect, but this difference was not statistically or clinically significant (P = .06). Subjectively, cannabinoid users either preferred their cannabinoid over Rx/OTC medications or liked both equally. Opioid use was higher among cannabinoid users (22.2% vs 12.5%), although this was not statistically significant (P = .28). CONCLUSION: Approximately 15% of new urban hand patients use cannabinoids for pain control, and these compounds have similar analgesic efficacy in hand pathologies as Rx/OTC medications. Cannabinoids are equally liked or preferred relative to traditional medications in this cohort, and they may play an important role in pain management for hand patients.

Vehicles for Consolidation and Expansion of Physician Practices: Private Equity, Medical Services Organizations, and Strategic Partnerships.

As reimbursements decline and the health care sector experiences consolidation, running a small practice is increasingly difficult. The past 15 years has seen a significant rise in practice consolidation, private equity investment, and regional health system affiliation. In a rapidly changing health care landscape, positioning one's practice for the future is challenging. The trade-off between financial stability and loss of control over the business and physician autonomy is often front and center in choosing our strategic partnerships. The long-term effects of these changes in practice dynamics on the quality and cost of care remain unknown but are concerning.

Hand Surgical Operating Room Size Allocation: A Comparative Space Utilisation Study.

Background: This study evaluated operating room (OR) space required for various hand surgical procedures. We analysed the size requirements for hand surgical cases divided into four settings: (1) large OR setting requiring fluoroscopy and microsurgical equipment, (2) medium-sized OR setting for cases requiring fluoroscopy, (3) smaller OR setting and (4) minor procedural room without anaesthesia with the aim to describe room size requirements for hand surgery practices. Methods: A variety of hand surgical cases were selected: large cases (microvascular digit replantation), medium-sized cases (closed reduction percutaneous pinning [CRPP] of phalangeal fractures) and smaller cases (carpal tunnel release [CTR]) with and without anaesthesia. Space requirements were compared to general surgery cases (laparoscopic appendectomy) and general orthopaedic surgery cases (cephalomedullary nail [CMN]). Necessary operative equipment was measured (ft2) to calculate requirements for each procedure. Results: Large hand cases such as digit replantation necessitated the most OR space (125 ft2), followed by general orthopaedic cases (CMN; 118 ft2), medium-sized hand cases (CRPP phalanx; 107 ft2), general surgery laparoscopic appendectomy (68 ft2), small hand cases (CTR; 85 ft2) and minor procedures (49 ft2). Conclusions: Hand procedures can be divided into major procedures requiring significant OR space (125 ft2), medium procedures in standard OR suites (107 ft2), procedures in small ORs with anaesthesia (81 ft2) or office-based setting without anaesthesia (49 ft2). These findings help define space utilisation for hand procedures and may have practical implications related to efficiency, cost and patient safety in the hospital and outpatient setting. Level of Evidence: Level IV (Economic and Decision Analyses).

Mixed Neuroendocrine-Squamous Cell Carcinoma of the Hand With Metastatic Dissemination: A Case Report.

Cutaneous manifestations of mixed neuroendocrine non-neuroendocrine neoplasms remain a diagnostic rarity. Predominantly identified within internal glandular organs, the digestive tract, and in the hepatobiliary system, this case report illustrates a unique occurrence of a mixed squamous cell and neuroendocrine tumor in the index finger of a justice-affected patient. We discuss the complexities of diagnosis and complications as well as emphasize the importance for hand surgeons to recognize presentations like this and the need for vigilant follow-up and improved care coordination.

The Learning Curve in Digital Replant Surgery: 46 Prospectively Collected Cases From a Single Surgeon Over a 10-Year Period.

PURPOSE:  Digital replantation is a technically difficult microsurgery requiring significant surgical skill. The aim of this study was to investigate postoperative outcomes associated with the surgical learning curve for microvascular digital replantation. METHODS:  A prospectively maintained surgical database of consecutive patients who underwent digital replantation from 2002 to 2012 was reviewed. All cases were performed by a single surgeon and began immediately after the surgeon's fellowship. A total of 46 patients were identified. Outcomes of digital replantation were tested for association with time since fellowship, total microvascular operative experience, and location and type of injury. RESULTS:  Overall, 38/46 (82.6%) of patients underwent a successful digital replantation. There was a significant difference between survival percentages over the years (p=0.04), with improvement seen over time. Total microvascular experience was significantly associated with successful outcomes (p<0.001). After 100 hours of microvascular experience, there was a significant increase in the survival odds ratio (OR 8.5, 95% CI 1.5-47.9). Crush and thumb injuries were more likely to have detrimental outcomes. CONCLUSIONS:  There was marked improvement in replant survival over time, with a significant increase in odds of survival after 100 hours of microvascular experience. One hundred operating hours under the microscope occurred around 2 years in practice for this high-volume surgeon. There is strong evidence that a steep learning curve occurs in microvascular digit replantation surgery.

Hospital transfers for evaluation and treatment of hand infections: Are all transfers necessary?

Background: Hand infections represent a common hand condition in the emergency department and one that frequently requires a hand specialist. The purpose of our study is to analyze hospital transfers for hand infections with a primary outcome being potential clinically avoidable transfers and to identify areas for improvement in the care of hand infections. Methods: Retrospective review of The Texas Healthcare Information Collection Database from 2015 to 2019. We analyzed all transfers for hand infections. Statistical analyses included: Transfer diagnosis, surgical interventions, length of stay (LOS), the day of the week that the transfer was initiated and whether or not the transfer or centralization was necessary or potentially avoidable. Results: A total of 3489 patients were transferred from one hospital to another for the management of a hand infection. 1628 (46.6 â€‹%) underwent at least one surgical intervention and 1861 (53.3 â€‹%) were treated non-operatively. Patients undergoing operative interventions had a lower LOS compared to those non-operatively. Transfers admitted during the weekend had decreased average LOS relative to non-weekend transfers, but a 94.7 â€‹% increased odds of receiving a relevant surgical intervention during the hospital admission. Nearly all patients were transferred to urban region hospitals. Of total, 1194 (34.22 â€‹%) were considered potentially avoidable centralizations, which we defined as transfer that resulted in no surgical intervention and discharge to home within 72 â€‹h. Conclusions: Although the reason for centralization was unknown, our analysis showed a high number of transfers that could have been potentially avoidable. We propose the development of specific guidelines, and perhaps the use of remote consultations for areas where hand specialist are not reliably available to help optimize the care of patient with hand infections.

A cross-sectional quantitative analysis of the readability and quality of online resources regarding thumb carpometacarpal joint replacement surgery.

Background: Thumb carpometacarpal (CMC) joint osteoarthritis is a common degenerative condition that affects up to 15 â€‹% of the population older than 30 years. Poor readability of online health resources has been associated with misinformation, inappropriate care, incorrect self-treatment, worse health outcomes, and increased healthcare resource waste. This study aims to assess the readability and quality of online information regarding thumb carpometacarpal (CMC) joint replacement surgery. Methods: The terms "thumb joint replacement surgery", "thumb carpometacarpal joint replacement surgery", "thumb cmc joint replacement surgery", "thumb arthroplasty", "thumb carpometacarpal arthroplasty", and "thumb cmc arthroplasty" were searched in Google and Bing. Readability was determined using the Flesch Reading Ease Score (FRES) and the Flesch-Kincaid Reading Grade Level (FKGL). FRES >65 or a grade level score of sixth grade and under was considered acceptable. Quality was assessed using the Patient Education Materials Assessment Tool (PEMAT) and a modified DISCERN tool. PEMAT scores below 70 were considered poorly understandable and poorly actionable. Results: A total of 34 websites underwent qualitative analysis. The average FRES was 54.60 â€‹± â€‹7.91 (range 30.30-67.80). Only 3 (8.82 â€‹%) websites had a FRES score >65. The average FKGL score was 8.19 â€‹± â€‹1.80 (range 5.60-12.90). Only 3 (8.82 â€‹%) websites were written at or below a sixth-grade level. The average PEMAT percentage score for understandability and actionability was 76.82 â€‹± â€‹9.43 (range 61.54-93.75) and 36.18 â€‹± â€‹24.12 (range 0.00-60.00) respectively. Although 22 (64.71 â€‹%) of websites met the acceptable standard of 70 â€‹% for understandability, none of the websites met the acceptable standard of 70 â€‹% for actionability. The average total DISCERN score was 32.00 â€‹± â€‹4.29 (range 24.00-42.00). Conclusions: Most websites reviewed were written above recommended reading levels. Most showed acceptable understandability but none showed acceptable actionability. To avoid the negative outcomes of poor patient understanding of online resources, providers of these resources should optimise accessibility to the average reader by using simple words, avoiding jargon, and analysing texts with readability software before publishing the materials online. Websites should also utilise visual aids and provide clearer pre-operative and post-operative instructions.

The Comparative Performance of Large Language Models on the Hand Surgery Self-Assessment Examination.

BACKGROUND: Generative artificial intelligence (AI) models have emerged as capable of producing human-like responses and have showcased their potential in general medical specialties. This study explores the performance of AI systems on the American Society for Surgery of the Hand (ASSH) Self-Assessment Exams (SAE). METHODS: ChatGPT 4.0 and Bing AI were evaluated on a set of multiple-choice questions drawn from the ASSH SAE online question bank spanning 5 years (2019-2023). Each system was evaluated with 999 questions. Images and video links were inserted into question prompts to allow for complete AI interpretation. The performance of both systems was standardized using the May 2023 version of ChatGPT 4.0 and Microsoft Bing AI, both of which had web browsing and image capabilities. RESULTS: ChatGPT 4.0 scored an average of 66.5% on the ASSH questions. Bing AI scored higher, with an average of 75.3%. Bing AI outperformed ChatGPT 4.0 by an average of 8.8%. As a benchmark, a minimum passing score of 50% was required for continuing medical education credit. Both ChatGPT 4.0 and Bing AI had poorer performance on video-type and image-type questions on analysis of variance testing. Responses from both models contained elements from sources such as PubMed, Journal of Hand Surgery, and American Academy of Orthopedic Surgeons. CONCLUSIONS: ChatGPT 4.0 with browsing and Bing AI can both be anticipated to achieve passing scores on the ASSH SAE. Generative AI, with its ability to provide logical responses and literature citations, presents a convincing argument for use as an interactive learning aid and educational tool.

Combined Distal Interphalangeal Joint Arthrodesis With Proximal Interphalangeal Joint Arthroplasty or Arthrodesis: Technical Considerations.

Combined distal interphalangeal joint (DIP) arthrodesis with proximal interphalangeal joint (PIP) arthroplasty or arthrodesis presents unique challenges. Although less common than isolated surgery for the DIP and PIP joints, with an aging population, combined DIP and PIP procedures are an increasingly encountered occurrence. Anatomical and morphological studies have provided length and width measurement standards for the middle and distal phalanges, allowing for planning to assess the compatibility of strategies. Besides reviewing anatomical studies to provide length and width guidelines for hardware placement, we will also discuss optimal hardware combinations for combined surgical intervention in the DIP and PIP joints. Conflict may exist between hardware used for the DIP arthrodesis and implants used for the PIP arthroplasty. As an example, if K-wires are used for DIP arthrodesis, any intervention in the PIP joint will be compatible. However, if headless screws are used for DIP arthrodesis, these should ideally not reach proximal to the midpoint of the middle phalanx. Other techniques, such as single or multiple oblique screws, and tension bands are compatible with PIP arthroplasty. Hence, options for management of the PIP joint are dependent on the technique used for DIP arthrodesis.

Trauma-induced dual-plane hemangioma in the hand: A case report.

INTRODUCTION AND IMPORTANCE: Hemangioma is a neoplastic disorder of vascular structures that can manifest at any site of the body. It is a rare ailment in general, and the intramuscular type is particularly uncommon and accounts for approximately 1 % of all hemangiomas. The presentation of hand hemangioma differs from other sites due to the restricted space and compression of vital structures, which frequently manifests as pain and functional impairment alongside mass. In this article, we present a case of trauma-induced dual-plane hemangioma in the hand. CASE PRESENTATION: A 55-year-old right-handed individual, without any significant medical background, sought medical attention for a painful mass on his right hand that had developed over the past year. He indicated a history of blunt trauma to the hand, with the mass becoming apparent two months post-injury. With the growth of the mass, the severity of pain progressively escalates; however, there is no loss of function observed. The diagnosis was established through duplex ultrasonography, and the patient received surgical excision utilizing the WALANT technique. Intraoperatively, the hemangioma was identified in two planes: one beneath the skin over the thenar eminence and another within the adductor pollicis muscle. The follow-up period proceeded without any complications or recurrence of the condition. CLINICAL DISCUSSION: Hand hemangiomas are relatively rare, and a history of trauma may lead to misdiagnosis as other conditions. There are various management strategies that are not suitable for hand hemangiomas. While surgical excision can alleviate symptoms, it carries the risk of increasing disability if muscle tissue is excised. CONCLUSION: Trauma-induced dual-plane hemangioma in the hand is a phenomenal condition that has been successfully treated surgically. Despite the removal of a portion of the adductor pollicis, both functional and aesthetic satisfaction was achieved. Hence, it is advisable to employ surgical management for such a presentation.

Expected outcome for reconstructive hand surgery after spinal cord injuries related to level of injury and sex.

This retrospective, multicentre study maps grip strength and grasp ability after tendon transfer surgery in patients with tetraplegia. Data were analysed in the whole group and in subgroups stratified into the International Classification for Surgery of the Hand in Tetraplegia (ICSHT) and sex. In total, 200 arms (143 patients) had tendon transfer surgery to restore grip and pinch function, 74% were men, 42% were ICSHT group ≤3 and 58% ICSHT were group ≥4. The one-year outcome across all participants for grip strength was 5.2 kg, pinch strength 2.1 kg and a score of 108 for the Grasp and Release test. Men had significantly higher grip and pinch strength compared to women, while there was no significant difference with respect to grasp ability. ICSHT group ≥4 had significantly higher grip strength and grasp ability compared to ICSHT group ≤3, whereas no significant difference in pinch strength between ICSHT groups was seen.Level of evidence: III.

Direct Variable Cost Comparison of Monitored Anesthesia Care Versus Wide Awake Local Anesthesia No Tournique Carpal Tunnel Release: A Time-Driven Activity-Based Costing Analysis.

PURPOSE: Time-driven activity-based costing (TDABC) provides a more accurate and granular estimation of direct variable costs compared with traditional accounting methods. This study used TDABC to quantitatively compare the same-day facility costs of open carpal tunnel release (CTR) performed under monitored anesthesia care (MAC) versus wide awake local anesthesia no tourniquet (WALANT). METHODS: We retrospectively identified 474 unilateral CTR (182 MAC and 292 WALANT) performed at an orthopedic specialty hospital between 2015 and 2021. Itemized facility costs were calculated using a TDABC algorithm. Patient demographics, surgical characteristics, and itemized costs were compared between those treated under MAC (MAC-CTR) and WALANT (WALANT-CTR). Multivariable regression was performed to determine the independent effect of MAC on true facility costs. RESULTS: Total facility costs were $170 higher in MAC-CTR compared with WALANT-CTR ($652 vs $482). Monitored anesthesia care-CTR cases had higher personnel costs ($537 vs $394), likely because of higher surgery personnel ($303 vs $185) and postanesthesia care unit personnel costs ($117 vs $95). Monitored anesthesia care-CTR cases also had higher supply costs ($119 vs $81). When controlling for demographics and comorbidities, MAC-CTR was independently associated with an increase in personnel costs by $150.65 (95% CI, $131.09-$170.21), supply costs by $24.99 (95% CI, $9.40-$40.58), and total facility costs by $175.66 (95% CI, $150.18-$201.09) per case. CONCLUSIONS: Using TDABC, MAC-CTR was found to be 35% more costly to the facility compared with WALANT-CTR. Notably, WALANT-CTR facility costs presented here do not include additional cost savings from anesthesiologist service fees or preoperative laboratory clearance required for MAC-CTR surgeries. To reduce costs related to CTR surgery, greater efforts should be made to reduce the number of intraoperative personnel and maximize the use of WALANT-CTR in an outpatient setting. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic and Decision Analysis II.

Wide-Awake Local Anesthesia No Tourniquet in hand surgery: A systematic review and meta-analysis.

WALANT (Wide Awake Local Anesthesia No Tourniquet) has been widely implemented in hand surgery. We conducted a systematic review from 1979 to 2022, led by a team of anesthesiologist. Only randomized studies comparing WALANT to other types of regional anesthesia were included. The outcomes studied were pain, duration of the procedure, intraoperative bleeding, complications, and patient satisfaction. Twelve articles were included in the analysis. We found a reduction of 2.77 on the VAS (95% CI -3.79; -1.75, I² 93%) for intraoperative pain in the WALANT group. There was no significant difference (MD 0.79, 95% CI 95% -0.11; 1.69, I² 73%) for duration of surgery. Patient satisfaction was consistently high in the WALANT group. Intraoperative bleeding was minimal and not clinically relevant. Compared to other types of regional anesthesia in hand surgery, the WALANT technique decreases pain for the patients without increasing the length of surgery.

Optimizing Outcomes in the Management of the Burned Hand.

Burns of the hand are prevalent and must be managed aggressively in the acute phase to prevent deformity and disability. Proper early wound management, achieving durable soft tissue coverage, and appropriate positioning in the acute period offer substantial benefits to patients long-term. When contractures occur, secondary procedures are often indicated, and they range from laser therapy to local/regional flap coverage; rarely free flaps are used. Boutonniere deformities are common, and unfortunately, at times finger amputation renders the hand more functional than further efforts at reconstruction.

RSTN COVID-19 Hand Recovery: Two years on, where are we now?

Hand surgery services were required to rapidly adapt to the coronavirus disease 2019 (COVID-19). Two years following the initial wave, hand surgery units continue to adapt and recover from the pandemic. The aim of the RSTN COVID-19 Hand Recovery survey was to evaluate what adaptions made to hand surgery services during COVID-19 have been maintained in the COVID recovery phase. A survey was distributed to hand surgery units, across the UK and Ireland. The survey was completed by consultant hand surgeons across 39 hospitals. Most practices returned to pre-pandemic standards. The main changes that endured were the increase in consultant-led triaging for referrals and utilisation of video conferencing platforms for teaching and meetings. Changes made during the pandemic, such as increased use of WALANT, out of theatre operating and use of telemedicine were not sustained during the recovery period. The COVID-19 pandemic allowed the opportunity for hand surgery services to adapt their services. Several changes that were implemented have since been proven to be more efficient and equally effective for patients. However, these changes have not been sustained and the barriers preventing permanent implementation should be scrutinised. We call on hand surgery units to evaluate their current practice to ensure that patients are provided a streamlined and sustainable service.

UK Trainee Experience with WALANT - An Audit of 102 Cases.

Background: WALANT has gained much popularity in recent years, especially with COVID-19. However, a recent survey of the American Society for Surgery of the Hand membership (i.e. attendings/consultants) showed that only 17% were exposed to WALANT during residency or fellowship training. There is much interest in WALANT from trainees, but interpretation of the type and volume to be administered is highly varied. Methods: The aims of this study were (1) to survey a group of plastic surgery trainees in the UK about their knowledge of WALANT formulas, and (2) to compare trainee logbook records of WALANT procedures (if available) with published data from the UK. Results: All trainees were familiar with the 'standard' WALANT formula (1% lidocaine, 1:100,000 adrenaline ± 8.4% NaHCO3) described by Lalonde. However, because of local formularies, rather than 1:100,000 adrenaline, all used 1:200,000 adrenaline as it comes premixed in the UK. Other formulas used by UK trainees included 0.5% bupivacaine + 1:200,000 adrenaline, and mixing 1% lidocaine + 1:200,000 adrenaline with 1% lidocaine 1:1. In comparing available trainee WALANT records with published UK data, the average volume of WALANT used was 6.6 mls in the current study versus 12.9 mls for similar procedures (wound debridement and skin closure ± local flap, digital nerve repair, fingertip reconstruction, thenar injuries, phalangeal fracture and single digit extensor repair); specifically, for single digit flexor tendon repairs, this was 10 mls versus 16.3 mls. Conclusions: While the British Society for Surgery of the Hand (BSSH) have developed official guidance for the use of WALANT in the UK, it appears there remains much variation in interpretation and hence, application. Comparison of trainee logbook records of common hand surgery procedures suggests that most can be done with much less WALANT administered than previously reported, with safe and reproducible results. Level of Evidence: Level IV (Therapeutic).

Simple, Office-Based Intervention Improves Patient-Provider Relationship in New Patient Hand Visits.

Purpose: Effective patient-doctor communication is linked to improved patient functional and physiological health status, better adherence to physician recommendations, and increased patient satisfaction. However, studies show that patients have difficulty understanding and recalling information discussed during a medical encounter. The purpose of this study was to assess patient engagement, patient-doctor communication, and patient-doctor interactions with the utilization of a patient encounter card to help aid in communication. Methods: New patients presenting to a single hand surgeon during an 8-month period between 2019 and 2020 were recruited for this study. Patients were recruited in pre and postintervention phases, defined by the rollout of a patient encounter card. Patients studied in the preintervention group were defined as the control population and experienced a typical office visit. The postintervention group experienced a typical office visit with the addition of a patient encounter card distributed to patients prior to meeting with the physician and screened by the physician during the visit to guide the encounter. Patient satisfaction and engagement surveys were collected during patient checkout process. Results: Two hundred eighty-seven patients (70% participation rate) were enrolled in the preintervention (145) and postintervention (142) phases. The utilization of a patient encounter card for setting a visit agenda resulted in a significant increase in self-reported patient engagement, improving from 74% to 88%. In both phases, 98% of patients felt that the physician listened well or very well and reported high levels of confidence in the provider being able to address their primary health concerns (72% and 79%, respectively). Overall, patient satisfaction was maintained pre and postintervention (96% and 98%, respectively). Conclusions: Use of the encounter card improved patients' feelings of engagement during their visits. Further research is required to determine the impact of these tools on providers' engagement and patient outcomes to improve quality of care in hand surgery. Type of study/level of evidence: Therapeutic II.
