Evidence-based Sterility: The Evolving Role of Field Sterility in Skin and Minor Hand Surgery

WALANT Decreases Costs of Surgery to Increase Access and Help Alleviate Poverty in East Africa

Surgery is essential to help people regain health and get back to work. Many Africans cannot afford traditional surgery because the sedation and main operating room sterility components are much too expensive. This often results in crushing debt for African families. Lack of access to surgery leads to poverty and poverty leads to lack of access to surgery. Wide-awake local anesthesia no tourniquet surgery, minimal pain tumescent local anesthesia, and evidence-based sterility are 3 disruptive game-changing innovations that eliminate the expensive general anesthesia and/or main operating room sterility components for many operations. Eliminating the tourniquet removes its need for sedation. Minimal pain tumescent local anesthesia enables comfortable numbing of large areas of the body to perform sedation-free operations such as soft tissue facial reconstruction, long bone fracture fixation, breast surgery, hernia repair, extremity surgery, and skin grafting. Evidence-based sterility has proven that many operations can be performed with field sterility outside of the main operating room environment with no significant increase in infection rates. No sedation also means no need for the main operating room environment. Moving some surgery out of the main operating room increases access for other operations that need full sterility to be accomplished. Since January 2020, these 3 disruptive changes have been adopted in 75 hospitals in 8 East African countries. This article documents how these changes have decreased the costs of surgery for the patients and, therefore, increased access to surgery, which helps alleviate poverty.

Main Operating Room Versus Field Sterility in Hand Surgery: A Review of the Evidence

Introduction: Many of the guidelines that are generally accepted as main operating room best practices are not evidence based. They are based on the concept that if some sterility is good, more must be better. They are not derived from evidence-based sterility. Evidence-based sterility is the study of which of our various sterility practices increase or decrease our infection rates, as opposed to guidelines based on how many bacteria are in the operating room. Methods: This article adds the most important evidence we could find that is not included in the first paper on evidence-based sterility in hand surgery published in 2019. In this review, we also balance the evidence with common sense opinion. Results: The 21st century has seen a rapid rise in the number and reports of hand surgery procedures performed with field sterility outside the main operating room. There is now an abundance of good evidence to support that the rate of infection is not higher when many hand operations are performed with field sterility in minor procedure rooms. Conclusion: Moving hand surgery out of the main operating room to minor procedure rooms should be supported by healthcare providers. The higher cost, increased solid waste, and inconvenience of main operating room surgery are not justifiable for many procedures because it does not reduce the risk of postoperative infection.

New Frontiers in Wide-Awake Surgery

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Explain the most important benefits of wide-awake surgery to patients. 2. Tumesce large parts of the body with minimal pain local anesthesia injection technique to eliminate the need for sedation for many operations. 3. Apply tourniquet-free surgery to upper and lower limb operations to avoid the sedation required to tolerate tourniquet pain. 4. Move many procedures out of the main operating room to minor procedure rooms with no increase in infection rates to decrease unnecessary cost and solid waste in surgery.

SUMMARY

Three disruptive innovations are changing the landscape of surgery: (1) minimally painful injection of large-volume, low-concentration tumescent local anesthesia eliminates the need for sedation for many procedures over the entire body; (2) epinephrine vasoconstriction in tumescent local anesthesia is a good alternative to the tourniquet and proximal nerve blocks in extremity surgery (sedation for tourniquet pain is no longer required for many procedures); and (3) evidence-based sterility and the elimination of sedation enable many larger procedures to move out of the main operating room into minor procedure rooms with no increase in infection rates. This continuing medical education article explores some of the new frontiers in which these changes affect surgery all over the body.

WALANT surgery of the hand: state of the art

Wide-awake local anesthesia no tourniquet is named the WALANT technique. WALANT has had a major positive impact on cost, convenience, ecology, patient satisfaction, access to surgical care, and outcomes in hand surgery in the last 20 years. Safe and efficient application of the technique is based on two principles. The first principle is the tumescent injection of a large volume low concentration 0.25-1% lidocaine, with 1:100 000-1:400 000 epinephrine. The second principle of WALANT is that the proper injection should be almost painless, with the patient only feeling the first needle poke of a tiny 30G needle. This wide awake patient approach reduces pain, neuropraxia, and systemic side effects of sedation with preservation of motor control, thereby aiding balanced reconstruction in hand surgery.

Current Trends in Use of Epinephrine in Hand Surgery

BACKGROUND

Epinephrine use during hand surgery has been stigmatized due to a fear of digital necrosis. Clinical experience in the past 2 decades has shown epinephrine in local anesthetic to be safe. We sought to analyze the use of epinephrine among hand surgeons and identify variables associated with it.

METHODS

A deidentified 21-question survey was distributed via email to the 914 and 415 members of the American Association for Hand Surgery and the Canadian Society for Surgery of the Hand, respectively. Questions included residency type, years of practice, practice setup/ownership, practice leadership, usage of epinephrine, availability of reversal agents, and reasons for or against usage.

RESULTS

Of 188 responders, 170 (90%) used epinephrine in local anesthetic for hand surgery procedures. By nationality, 100% (43) of Canadian surgeons and 89% (108) of US surgeons use epinephrine (P = .01). Among surgeons with practice ownership, 88% (102) used epinephrine compared with 93% (85) of those surgeons that we employed (P = .28). Comparing surgeons with teaching responsibilities versus those without training responsibilities showed that surgeons who did not teach used epinephrine at a higher rate (87% vs 98%, P = .04). In addition, plastic surgery-trained surgeons (111) used epinephrine in 97.2% of cases while orthopedic surgery-trained surgeons (57) used epinephrine in 80.2% of cases (P = .0003). No difference was found when examining the use of epinephrine and surgeon age (P = .28).

CONCLUSIONS

Most respondents believe that epinephrine is safe. Training background, location, and practice setup are significant factors in the use of epinephrine, whereas practice ownership and physician age are not major factors.

Tips, Tricks, and Pearls for a Superior Patient and Surgeon Experience for Wide-awake Dupuytren Surgery

Fasciectomy for Dupuytren disease is a common procedure traditionally performed with a tourniquet under general or regional anesthesia. Since the year 2001, the wide-awake local anesthesia no tourniquet (WALANT) approach has been applied successfully to Dupuytren surgery, with current excellent surgeon and patient satisfaction. However, using WALANT for Dupuytren surgery may be intimidating for hand surgeons who want to begin using this method. The purpose of this article is to offer a series of tips and tricks the authors have learned after having performed hundreds of WALANT fasciectomies, to make this technique easier for surgeons and a more pleasurable experience for patients.

With mindful use of resources, both profitability and the well-being of patients and doctors can align with environmental protection.

Greening Hand Surgery: Targeted Measures to Reduce Waste in Ambulatory Trigger Finger and Carpal Tunnel Decompression

BACKGROUND

Operating rooms (ORs) produce approximately 70% of hospital waste. Greening strategies in the OR aim to reduce the environmental impact of surgery while maintaining patient safety and outcomes. The aim of this study was to strategically reduce waste and cost associated with common ambulatory hand procedures by implementing a 3-stage "green case" plan over a 1-year period in a high-volume tertiary referral hand surgery division.

METHODS

A 3-stage greening initiative for hand surgery was designed and implemented in ambulatory open carpal tunnel release (CTR) and trigger finger release (TFR) cases, including: (1) introduction of minor field sterility; (2) implementation of a lean and green minor hand surgery pack and reduced instrument set; and (3) elimination of gown use by surgeons and OR staff. Surgical supply usage and costs were tracked during the study period and compared with control.

RESULTS

Each "green case" resulted in savings of $105 compared with the control cases from the preceding year, excluding cost savings associated with reduced waste processing. There was a 64% and 75% reduction in waste and costs after greening, respectively. This equates to a minimum institutional annual savings of $51 000 when used for CTR and TFR. There was no observed increase in surgical site infections or complications after the introduction of greening.

CONCLUSION

Greening initiatives can be successfully implemented by surgeons to reduce waste and costs. With targeted greening of CTR and TFR procedures, we significantly reduced waste and decreased costs while maintaining patient safety and outcomes.

Successful Shoulder Disarticulation under Local Anesthesia in the COVID-19 Era

The use of the wide-awake local anesthesia no tourniquet, a tumescent local anesthetic technique in recent years, emerged as a powerful tool primarily in hand surgery. It has been adopted in many low- and middle-income countries where it was applied to an increasingly broad group of procedures. We report the case of an older patient with an arm liposarcoma for which surgery under general or regional anesthesia was deemed unsafe, but was successfully managed with a curative right shoulder disarticulation using tumescent local anesthesia.

How Ophthalmologists Can Decarbonize Eye Care: A Review of Existing Sustainability Strategies and Steps Ophthalmologists Can Take

TOPIC

Understanding approaches to sustainability in cataract surgery and their risks and benefits.

CLINICAL RELEVANCE

In the United States, health care is responsible for approximately 8.5% of greenhouse gas (GHG), and cataract surgery is one of the most commonly performed surgical procedures. Ophthalmologists can contribute to reducing GHG emissions, which lead to a steadily increasing list of health concerns ranging from trauma to food instability.

METHODS

We conducted a literature review to identify the benefits and risks of sustainability interventions. We then organized these interventions into a decision tree for use by individual surgeons.

RESULTS

Identified sustainability interventions fall into the domains of advocacy and education, pharmaceuticals, process, and supplies and waste. Existing literature shows certain interventions may be safe, cost-effective, and environmentally friendly. These include dispensing medications at home to patients after surgery, multi-dosing appropriate medications, training staff to properly sort medical waste, reducing the number of supplies used during surgery, and implementing immediate sequential bilateral cataract surgery where clinically appropriate. The literature was lacking on the benefits or risks for some interventions, such as switching specific single-use supplies to reusables or implementing a hub-and-spoke-style operating room setup. Many of the advocacy and education interventions have inadequate literature specific to ophthalmology but are likely to have minimal risks.

CONCLUSIONS

Ophthalmologists can engage in a variety of safe and effective approaches to reduce or eliminate dangerous GHG emissions associated with cataract surgery.

Gut Microbiota and Liver Transplantation: Immune Mechanisms behind the Rejection

Liver transplantation (LT) is the treatment of choice for patients with cirrhosis, decompensated disease, acute liver failure, and hepatocellular carcinoma (HCC). In 3-25% of cases, an alarming problem is acute and chronic cellular rejection after LT, and this event can lead to the need for new transplantation or the death of the patient. On the other hand, gut microbiota is involved in several mechanisms sustaining the model of the "gut-liver axis". These include modulation of the immune response, which is altered in case of gut dysbiosis, possibly resulting in acute graft rejection. Some studies have evaluated the composition of the gut microbiota in cirrhotic patients before and after LT, but few of them have assessed its impact on liver rejection. This review underlines the changes in gut microbiota composition before and after liver transplantation, hypothesizing possible immune mechanisms linking dysbiosis to transplantation rejection. Evaluation of changes in the gut microbiota composition in these patients is therefore essential in order to monitor the success of LT and eventually adopt appropriate preventive measures.

Is Hand Surgery in the Procedure Room Setting Associated with Increased Surgical Site Infection? A Cohort Study of 2,717 Patients in the Veterans Affairs Population

PURPOSE

Procedure rooms (PRs) are increasingly used for hand surgeries, but few studies have directly compared surgical site infection (SSI) rates between the PR and operating room. We tested the hypothesis that procedure setting is not associated with an increased SSI incidence in the VA population.

METHODS

We identified carpal tunnel, trigger finger, and first dorsal compartment releases performed at our VA institution from 1999 to 2021 of which 717 were performed in the main operating room and 2,000 were performed in the PR. The incidence of SSI, defined as signs of wound infection within 60 days of the index procedure, which was treated with oral antibiotics, intravenous antibiotics, and/or operating room irrigation and debridement, was compared. We constructed a multivariable logistic regression analysis to assess the association between procedure setting and SSI incidence, adjusting for age, sex, procedure type, and comorbidities.

RESULTS

Surgical site infection incidence was 55/2,000 (2.8%) in the PR cohort and 20/717 (2.8%) in the operating room cohort. In the PR cohort, five (0.3%) cases required hospitalization for intravenous antibiotics of which two (0.1%) cases required operating room irrigation and debridement. In the operating room cohort, two (0.3%) cases required hospitalization for intravenous antibiotics of which one (0.1%) case required operating room irrigation and debridement. All other SSIs were treated with oral antibiotics alone. The procedure setting was not independently associated with SSI (adjusted odds ratio, 0.84 [95% confidence interval, 0.49, 1.48]). The only risk factor for SSI was trigger finger release (odds ratio, 2.13 [95% confidence interval, 1.32, 3.48] compared with carpal tunnel release), which was independent of setting.

CONCLUSIONS

Minor hand surgeries can be performed safely in the PR without an increased rate of SSI.

Optimizing the Use of Operating Rooms by Transitioning Common Hand Surgeries Into the Office Setting

PURPOSE

The purpose of this study was to examine the true monetary implications, at the health system level, of moving simple hand procedures, performed with wide-awake local anesthesia no tourniquet surgery, from the ambulatory surgery center (ASC) to office setting.

METHODS

We analyzed the costs, revenues, case times, and patient demographics for 2 cohorts of patients who underwent hand and non-hand surgical procedures over a 2-year period. We calculated the mean margin per minute for the top 5 procedures in non-hand orthopedic surgery subgroups, complex plastics hand, and non-hand plastic surgery. We then calculated the following: (1) hours operating room or ASC time gained by moving hand procedures to the office, (2) additional subgroup patients theoretically treated by using the ASC hours gained, and (3) net margin (in dollars) because of additional procedures.

RESULTS

Six board-certified hand surgeons performed 623 simple ASC and 808 in-office procedures, consisting of 795 carpal tunnel releases, 84 first dorsal compartment releases, and 446 trigger finger releases. The net margin per minute for simple ASC and in-office hand procedures was $25.01/min and $5.63/min, respectively. In the office setting, hand surgery freed up 821 hours of ASC time, which could be theoretically used to treat over 300 additional patients awaiting outpatient orthopedic hand or plastic surgery. Depending on the subspecialty and type of substituted cases, the theoretical net margin varied from -$150,413 to $3.9 million.

CONCLUSIONS

Transitioning simple hand operations out of ASCs realized a mean cost savings of 82% per case ($1,137 vs $206) and effectively opened 821 additional hours of operating room time over a 2-year period.

CLINICAL RELEVANCE

Transitioning simple hand operations out of the operating room setting and into the office setting reduces the cost of hand surgical care, improves operating room access for alternate procedures or patients, and validates the sustainability of safe and effective wide-awake local anesthesia no tourniquet surgery from a hospital system's financial standpoint.

Guidelines for Wide-Awake Local Anesthesia Surgery with No Tourniquet in the Office Setting Using Field Preparation Sterility

SUMMARY

Wide-awake local anesthesia surgery with no tourniquet, or WALANT, has become popular in surgery, especially among hand surgeons. With the increasing number of surgeons performing office-based procedures, this article provides guidelines that may be used in the office setting to help transition more traditional hospital operating room-based procedures to the office setting. This article outlines the benefits of performing office-based wide-awake local anesthesia surgery with no tourniquet and provides a step-by-step guide to performing procedures that can be easily incorporated into any hand surgeon's practice successfully and safely.

Future studies are needed to further these initiatives on quantifying and decreasing environmental impact and furthering sustainable use of our resources.

Thinking Outside the Operating Room: Guidance on Designing a Safe and Effective Minor Procedure Room

The minor procedure room (MPR) offers numerous advantages over the traditional operating room for performing many common hand surgeries. MPRs require less space, are subject to more practical architectural design standards, and facilitate more judicious use of disposable materials and unnecessary instruments than common hand surgeries. MPRs reduce costs to the system and patient at every step of the surgical workflow and improve efficiency by removing preoperative and postoperative monitoring requirements. Hand surgeons sometimes face resistance when attempting surgery in MPRs, often because of confusion about their design characteristics and capabilities. This article aims to clarify many of the major requirements for establishing an MPR and provide a guide to hand surgeons for performing safe, efficient surgery outside the operating room.

Internal Fixation of Finger Fractures: Field Sterility for Surgery and Earlier Removal of K-Wires Are Safe

Field sterility for K-wire insertion outside the main operating room is much cheaper and greener (ie, there is less waste). It permits increased access to more affordable surgery because unnecessary sedation and full sterility are eliminated. Early pain-guided protected movement of K-wired finger fractures at 3 to 5 days leads to less stiffness. It will not result in loss of reduction or infection around K-wires if patients avoid "pain" (ie, do not perform movements that hurt). Early protected movement and early removal of K-wires at 2 to 4 weeks contribute to less stiffness after operative hand/finger fracture reduction and stabilization.

Optimization of Carpal Tunnel Syndrome Using WALANT Method

As surgical management of carpal tunnel release (CTR) becomes ever more common, extensive research has emerged to optimize the contextualization of this procedure. In particular, CTR under the wide-awake, local-anesthesia, no-tourniquet (WALANT) technique has emerged as a cost-effective, safe, and straightforward option for the millions who undergo this procedure worldwide. CTR under WALANT is associated with considerable cost savings and workflow efficiencies; it can be safely and effectively executed in an outpatient clinic under field sterility with less use of resources and production of waste, and it has consistently demonstrated standard or better post-operative pain control and satisfaction among patients. In this review of the literature, we describe the current findings on CTR using the WALANT technique.

WALANT: A Discussion of Indications, Impact, and Educational Requirements

Wide-awake, local anesthesia, no tourniquet (WALANT) is a technique that removes the requirement for operations to be performed with a tourniquet, general/regional anesthesia, sedation or an anesthetist. We reviewed the WALANT literature with respect to the diverse indications and impact of WALANT to discuss the importance of future surgical curriculum integration. With appropriate patient selection, WALANT may be used effectively in upper and lower limb surgery; it is also a useful option for patients who are unsuitable for general/regional anesthesia. There is a growing body of evidence supporting the use of WALANT in more complex operations in both upper and lower limb surgery. WALANT is a safe, effective, and simple technique associated with equivalent or superior patient pain scores among other numerous clinical and cost benefits. Cost benefits derive from reduced requirements for theater/anesthetic personnel, space, equipment, time, and inpatient stay. The lack of a requirement for general anesthesia reduces aerosol generating procedures, for example, intubation/high-flow oxygen, hence patients and staff also benefit from the reduced potential for infection transmission. WALANT provides a relatively, but not entirely, bloodless surgical field. Training requirements include the surgical indications, volume calculations, infiltration technique, appropriate perioperative patient/team member communication, and specifics of each operation that need to be considered, for example, checking of active tendon glide versus venting of flexor tendon pulleys. WALANT offers significant clinical, economic, and operative safety advantages when compared with general/regional anesthesia. Key challenges include careful patient selection and the comprehensive training of future surgeons to perform the technique safely.

Infection Rate Comparison during Transition from Hospital to Office WALANT Enabled by Virtual Reality

We transitioned our hand practice from the operating room (OR) to our office-based procedure room (OPR) to offer wide-awake, local anesthesia, no tourniquet (WALANT). We have established that using wide-awake virtual reality improves patient comfort and anxiety during wide-awake procedures and helps facilitate our patients’ choice of venue. We aimed to assess the effect of this transition on infection rates for procedures performed by a single surgeon in the OR versus the OPR.

Ten Questions About Wide Awake Local Anaesthesia No Tourniquet (WALANT) Surgery

The aim of this review article is to provide many important tips and tricks for surgeons to start Wide Awake Local Anaesthesia No Tourniquet (WALANT) hand surgery in their practice. The massive cost reduction of this disruptive new approach will enable them to increase access to hand surgery for their patients who cannot afford unnecessary sedation or unnecessary sterility of the expensive main operating room environment. Evidence-based sterility will permit surgeons to move a lot of their surgery out of the main operating room to minor procedure rooms without a significant increase in infection rates. Important pointers on how to inject minimally painful local anaesthesia will have patients thinking the surgeon injector is a bit of a magician. WALANT enables surgeons to improve the outcomes of many hand surgery procedures. Level of Evidence: Level V (Therapeutic).

Variability in personal protective equipment in cross-sectional interventional abdominal radiology practices

Purpose

To determine institutional practice requirements for personal protective equipment (PPE) in cross-sectional interventional radiology (CSIR) procedures among a variety of radiology practices in the USA and Canada.

Methods

Members of the Society of Abdominal Radiology (SAR) CSIR Emerging Technology Commission (ETC) were sent an eight-question survey about what PPE they were required to use during common CSIR procedures: paracentesis, thoracentesis, thyroid fine needle aspiration (FNA), superficial lymph node biopsy, deep lymph node biopsy, solid organ biopsy, and ablation. Types of PPE evaluated were sterile gloves, surgical masks, gowns, surgical hats, eye shields, foot covers, and scrubs.

Results

26/38 surveys were completed by respondents at 20/22 (91%) institutions. The most common PPE was sterile gloves, required by 20/20 (100%) institutions for every procedure. The second most common PPE was masks, required by 14/20 (70%) institutions for superficial and deep procedures and 12/12 (100%) institutions for ablation. Scrubs, sterile gowns, eye shields, and surgical hats were required at nearly all institutions for ablation, whereas approximately half of institutions required their use for deep lymph node and solid organ biopsy. Compared with other types of PPE, required mask and eye shield use showed the greatest increase during the SARS-CoV-2 pandemic.

Conclusion

PPE use during common cross-sectional procedures is widely variable. Given the environmental and financial impact and lack of consensus practice, further studies examining the appropriate level of PPE are needed.

Important updates of finger fractures, entrapment neuropathies and wide-awake surgery of the upper extremity

Hand surgery is rapidly changing. The wide-awake approach, minimum dissection surgery and early protected movement have changed many things. This is an update of some of the important changes regarding early protected movement with K-wired finger fracture management, simplification of nerve decompression surgery, such as elbow median and ulnar nerve releases, and some new areas in performing surgery with wide-awake local anaesthesia without tourniquet.

How to Minimize the Pain of Local Anesthetic Injection for Wide Awake Surgery

After reading this article, the participant should be able to (1) almost painlessly inject tumescent local anesthesia to anesthetize small or large parts of the body, (2) improve surgical safety by eliminating the need for unnecessary sedation in patients with multiple medical comorbidities, and (3) convert many limb and face operations to wide awake surgery. We recommend the following 13 tips to minimize the pain of local anesthesia injection: (1) buffer local anesthetic with sodium bicarbonate; (2) use smaller 27- or 30-gauge needles; (3) immobilize the syringe with two hands and have your thumb ready on the plunger before inserting the needle; (4) use more than one type of sensory noise when inserting needles into the skin; (5) try to insert the needle at 90 degrees; (6) do not inject in the dermis, but in the fat just below it; (7) inject at least 2 ml slowly just under the dermis before moving the needle at all and inject all local anesthetic slowly when you start to advance the needle; (8) never advance sharp needle tips anywhere that is not yet numb; (9) always inject from proximal to distal relative to nerves; (10) use blunt-tipped cannulas when tumescing large areas; (11) only reinsert needles into skin that is already numb when injecting large areas; (12) always ask patients to tell you every time they feel pain during the whole injection process so that you can score yourself and improve with each injection; (13) always inject too much volume instead of not enough volume to eliminate surgery pain and the need for "top ups."

WALANT Hand and Upper Extremity Procedures Performed With Minor Field Sterility Are Associated With Low Infection Rates

Background:

The use of minor field sterility in hand/upper extremity cases has been shown to improve workflow efficiency while maintaining patient safety. As this finding has been limited to specific procedures, we investigated the safety of performing a wide array of hand/upper extremity procedures outside the main operating room using minimal field sterility with Wide-Awake Local Anaesthesia No Tourniquet (WALANT) anaesthesia by evaluating superficial and deep infection rates across a diverse series of cases.

Methods:

This study was a case series conducted between October 2017 and June 2020. Of all, 217 patients underwent hand/upper extremity procedures performed in a minor procedure room via WALANT technique with field sterility. Primary outcome measures include superficial and deep surgical site infections within 14 days post-surgery.

Results:

Of all, 217 patients were included in this study; 265 consecutive hand/upper extremity operations were performed by a single surgeon, with notable case diversity. The majority of patients (n = 215, 99.1%) did not report or present with signs of infection before or after their operation. We report 0% 14-day and 0.37% 30-day surgical site infection rates for such hand/upper extremity procedures performed in a minor procedure room with field sterility.

Conclusion:

Hand/upper extremity procedures performed via WALANT technique with field sterility in a minor procedure room are associated with low surgical site infection rates. These rates are comparable to surgical site infection rates for similar surgeries performed in main operating rooms with standard sterilization procedures. Thus, the implementation of this technique may allow for improved workflow efficiency and reduced waste, all while maintaining patient safety.

Outcomes of Orthopedic Hand Surgeries in Minor Procedure Rooms at a Veterans Affairs Medical Center

Purpose

There is a high demand for minor hand surgeries within the veteran population. The objective of this study was to compare clinical outcomes and resource use at a Veterans Affairs Medical Center (VAMC) of hand surgeries performed in minor procedure rooms (MPR) and operating rooms using local anesthesia with or without monitored anesthesia care.

Methods

We retrospectively evaluated all patients undergoing carpal tunnel release, de Quervain's release, foreign body removal, soft tissue mass excision, or A1 pulley release at a VAMC over a 5-year period. Data collected included demographic information, mental health comorbidities, presence of preoperative and postoperative pain, complications after surgery, time to surgery, number of personnel in surgery, turnover time between cases, and time spent in the postanesthesia care unit. Statistical analysis included Fisher exact or chi-square analysis to compare MPR versus operating room groups and Student t test or Mann-Whitney test to compare continuous variables.

Results

In this cohort of 331 cases, 123 and 208 patients underwent surgery in MPRs and operating rooms, respectively. Preoperative and postoperative pain were similar between the MPR and operating room groups. Complications were slightly lower in the MPR group versus the operating room group (0% MPR vs 2.9% operating room). Median time from surgical consult to surgery was 6 days less for MPR patients (15 vs 21). The MPR cases also used fewer personnel during surgery, averaging 4.76 versus 4.99 people. The MPR patients spent 9 minutes less in the postanesthesia care unit (median, 36 vs 45 minutes) and turnover time between cases was nearly 8 minutes faster in MPRs than in operating rooms (median, 20 vs 28 minutes).

Conclusions

Minor procedure rooms at a VAMC allow more veteran patients to be scheduled for minor hand surgeries within a shorter time frame, utilize less staff and postoperative monitoring, and maintain excellent outcomes with limited complications.

Clinical relevance

Minor hand surgeries in MPRs have outcomes equivalent to those of operating rooms with improved time savings and resource use.

Carbon footprint of dermatologic surgery

Healthcare is a potent emitter of greenhouse gases amounting up to 7% of total estimated greenhouse gas emissions (CO₂ e) for Australia. Australia has one of the highest incidences of skin cancer in the world but there is a paucity of data on the ecological impact of skin cancer excision/dermatologic surgery. The authors reviewed the various impact inventories in order to perform a life cycle assessment of skin cancer excision. A total of 8641 tonnes of estimated CO₂ e are produced from dermatologic surgery annually in Australia (6751 tonnes from private clinical rooms and 1890 tonnes from hospitals) and the waste generated contributes significantly to terrestrial ecotoxicity and acidification of land and water. Various means can be carried out to reduce this impact, ranging from simple behavioural changes to larger, policy changes.

Incorporating Office-Based Surgery Into Your Practice With WALANT

Office-based surgery (OBS) with wide-awake local anesthesia no tourniquet (WALANT) surgery is a safe and cost-effective care model that is convenient for patient and provider alike. Currently, the practice is growing, but in the majority of North America the ambulatory-care center is still the most common setting for hand surgery. This article discusses the practical issues of implementing OBS with WALANT including clinical setup and workflows for OBS, negotiating payor contracts, and managing liability.

Four Ways Plastic Surgeons Can Fight Climate Change

The climate crisis demands that surgeons reduce their environmental impact. Operating rooms are resource-intensive and are often wasteful. This makes them fitting targets for climate-conscious decision making.

Doing Our Part to Conserve Resources: Determining Whether All Personal Protective Equipment Is Mandatory for Closed Reduction and Percutaneous Pinning of Supracondylar Humeral Fractures

BACKGROUND

Closed reduction and percutaneous pinning (CRPP) of supracondylar humeral fractures is one of the most common procedures performed in pediatric orthopaedics. The use of full, standard preparation and draping with standard personal protective equipment (PPE) may not be necessary during this procedure. This is of particular interest in the current climate as we face unprecedented PPE shortages due to the current COVID-19 pandemic.

METHODS

This is a retrospective chart review of 1,270 patients treated with CRPP of a supracondylar humeral fracture at 2 metropolitan pediatric centers by 10 fellowship-trained pediatric orthopaedic surgeons. One surgeon in the group did not wear a mask when performing CRPP of supracondylar humeral fractures, and multiple surgeons in the group utilized a semisterile preparation technique (no sterile gown or drapes). Infectious outcomes were compared between 2 groups: full sterile preparation and semisterile preparation. We additionally analyzed a subgroup of patients who had semisterile preparation without surgeon mask use. Hospital cost data were used to estimate annual cost savings with the adoption of the semisterile technique.

RESULTS

In this study, 1,270 patients who underwent CRPP of a supracondylar humeral fracture and met inclusion criteria were identified. There were 3 deep infections (0.24%). These infections all occurred in the group using full sterile preparation and surgical masks. No clinically relevant pin-track infections were noted. There were no known surgeon occupational exposures to bodily fluid. It is estimated that national adoption of this technique in the United States could save between 18,612 and 22,162 gowns and masks with costs savings of $3.7 million to $4.4 million annually.

CONCLUSIONS

We currently face critical shortages of PPE due to the COVID-19 pandemic. Data from this large series suggest that a semisterile technique during CRPP of supracondylar humeral fractures is a safe practice. We anticipate that this could preserve approximately 20,000 gowns and masks in the United States over the next year. Physicians are encouraged to reevaluate their daily practice to identify safe opportunities for resource preservation.

Sterility and cost of gloves during Mohs micrographic surgery: Sterile or peril?

In recent years, the focus in the field of health care has shifted toward cost-saving strategies without the sacrifice of patient safety and clinical outcomes. Therefore, we decided to look into the use of nonsterile gloves and sterile gloves during Mohs micrographic surgery. This practice varies widely between Mohs surgeons. However, studies have shown no differences in infection rates. Here, we review the pertinent studies and also combine the data to offer readers an overall financial analysis.
