Evaluation of the COVID-19 Infection Rate in the Perioperative Period of Elective Surgeries of the Hand and Microsurgery.

BACKGROUND: After the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (coronavirus disease 2019 [COVID-19]), the world started reducing the number of elective surgeries to reduce the transmission of the coronavirus. Some priority elective surgeries were performed, and there was no increase in contagion rates due to safety protocols and protection measures. The study aims to present the coronavirus infection rate of elective hand surgeries and microsurgery performed during pandemics. METHODS: A retrospective study evaluating 188 patients submitted to elective surgical procedures. The exclusion criteria were patients infected by COVID-19 before the surgery and patients who submitted to trauma surgery. Only 108 patients were eligible for this study. The mean age was 47.8 years (range: 15 days-81 years). There were 63 females and 45 males. They were divided into 2 groups: outpatient (n = 49) and inpatient (n = 59) procedures. RESULTS: The overall COVID infection rate was 6.48%. The outpatient infection rate was 2.08%, whereas the inpatient infection rate was 10.17% (Student t test: P = .089). The main factor correlated with infection in the postoperative period was the number of postoperative outpatient visits (Student t test: P = .089). No statistical differences were observed between the variables studied, but there was a tendency for patients who submitted to inpatient surgery to get infected by COVID-19 (P = .089). The statistical power was 0.8 (Cohen's d test), showing that large samples are needed to analyze the correlation better. CONCLUSION: We concluded that the safety of performing elective hand surgery during the pandemic remains unclear, and more studies with larger samples are needed.

Comparison of Patient Perception and Satisfaction of Face-to-Face Versus Telemedicine Encounters in Hand Surgery.

BACKGROUND: The coronavirus disease 2019 (COVID-19) surge has enabled the widespread usage of telemedicine (TM) and presents a unique opportunity to determine the hand surgery patients' perception of care using validated patient satisfaction scores. METHODS: Electronic surveys were distributed to patients aged 18 years and older who underwent a video TM encounter with a single surgeon at an academic medical center during the initial COVID-19 surge (March 23 to October 22, 2020). The study-specific questions were derived from the Press Ganey (PG) Medical Practice TM Survey and compared with institutional PG Outpatient Medical Practice Survey data. Three cohorts were defined: pre-COVID face-to-face, post-COVID TM, and post-COVID face-to-face. RESULTS: Thirty of 65 TM patients (46.2%) responded. No differences in sex, age, or visit type were identified between cohorts. The TM cohort was more likely to live greater than 300 miles from the institution. Median response for all cohorts for the PG care provider and overall experience responses were "very good," and no differences were identified between cohorts. Patient satisfaction with their TM experience was high with median satisfaction scores for arranging and connecting to a TM visit, talking with the provider over a video connection, and having the provider understand the clinical problem were "very good." Patients in the TM cohort reported no difference in preference for face-to-face or TM visits. CONCLUSIONS: Patients are satisfied with TM as a substitute for face-to-face visits suggesting that TM can possibly be used to deliver comparable patient experience for hand surgery encounters.

Implementation of Clean Hospital Strategy and Prioritizing Covid-19 Prevention Factors Using Best-Worst Method.

Many nations have suffered the catastrophe of COVID-19, and one of the first countries affected by the pandemic was Iran; all industries and individuals have been adversely affected by the pandemic. Health care systems and patients' conditions, in particular, were disrupted due to canceling elective surgery. To put it more sharply, a delay in performing elective surgery may potentially impact patients' survival and the quality of their lives. To cope with the new situation, in the first stage, the Clean Hospital strategy was proposed in order to minimize the effects of this pandemic on elective surgical services. The mentioned strategy is a try to provide a solution and resume elective surgeries in the pandemic period. In the second stage, panel discussion, Delphi method, and the best-worst method (BWM) were employed to prioritize the factors that inhibit Coronavirus transmission. The proposed strategy and the results of this study could be used by policymakers and health departments to resume elective surgeries and control the infection to maintain a hospital or a section of it clear. The overall result of the study showed that the most important Covid-19 prevention factors in Clean Hospitals were personal protection (w = 0.212), screening checklist (w = 0.182), and check body temperature (w = 0.126), respectively (C1 > C2 > C3). According to the financial, time, and human resource limitations, first, resources were allocated to higher priority criteria, and in order of priority, all items (C1, C2, …., C9) were used in the Clean hospital strategy.

The COVID-19 pandemic and follow-up for shoulder surgery: The impact of a shift toward telemedicine on validated patient-reported outcomes.

INTRODUCTION: The emergence of COVID-19 and its ensuing restrictions on in-person healthcare has resulted in a sudden shift towards the utilization of telemedicine. The purpose of this study is to assess patient satisfaction and patient-reported outcome measures (PROMs) for individuals who underwent follow-up for shoulder surgery using telemedicine compared to those who received traditional in-person clinic follow-up. METHODS: Patients who underwent either rotator cuff repair or total shoulder arthroplasty during a designated pre-COVID-19 (traditional clinic follow-up) or peri-COVID-19 (telemedicine follow-up) span of time were identified. PROMs including the American Shoulder and Elbow Surgeons standardized assessment form, the three-level version of the EQ-5D form, the 12-Item Short Form survey, and a modified version of a published telemedicine survey were administered to participants six months post-operatively via phone call. RESULTS: Sixty patients agreed to participate. There was no significant difference between the pre-COVID-19 and peri-COVID-19 groups in patient satisfaction with their follow-up visit (p = 0.289), nor was there a significant difference in PROMs between the two groups. In total, 83.33% of the telemedicine group and 70.37% of the in-person clinic group preferred traditional in-person follow-up over telemedicine. DISCUSSION: In a cohort of patients who underwent telemedicine follow-up for shoulder surgery during the COVID-19 pandemic, there was no difference in patient satisfaction and PROMs compared to traditional in-person clinic follow-up. This study indicates that while the majority of participants preferred face-to-face visits, patients were relatively satisfied with their care and had similar functional outcome scores in both groups, despite the large disruption in healthcare logistics caused by COVID-19.

Telemedicine in Spine Surgery: Global Perspectives and Practices.

STUDY DESIGN: Cross-sectional, anonymous, international survey. OBJECTIVES: The COVID-19 pandemic has resulted in the rapid adoption of telemedicine in spine surgery. This study sought to determine the extent of adoption and global perspectives on telemedicine in spine surgery. METHODS: All members of AO Spine International were emailed an anonymous survey covering the participant's experiences with and perceptions of telemedicine. Descriptive statistics were used to depict responses. Responses were compared among regions. RESULTS: 485 spine surgeons participated in the survey. Telemedicine usage rose from <10.0% to >39.0% of all visits. A majority of providers (60.5%) performed at least one telemedicine visit. The format of "telemedicine" varied widely by region: European (50.0%) and African (45.2%) surgeons were more likely to use phone calls, whereas North (66.7%) and South American (77.0%) surgeons more commonly used video (P < 0.001). North American providers used telemedicine the most during COVID-19 (>60.0% of all visits). 81.9% of all providers "agreed/strongly agreed" telemedicine was easy to use. Respondents tended to "agree" that imaging review, the initial appointment, and postoperative care could be performed using telemedicine. Almost all (95.4%) surgeons preferred at least one in-person visit prior to the day of surgery. CONCLUSION: Our study noted significant geographical differences in the rate of telemedicine adoption and the platform of telemedicine utilized. The results suggest a significant increase in telemedicine utilization, particularly in North America. Spine surgeons found telemedicine feasible for imaging review, initial visits, and follow-up visits although the vast majority still preferred at least one in-person preoperative visit.

The Virtual Interview Experience for MATCH 2021: A Pilot Survey of General Surgery Residency Program Directors.

BACKGROUND: Virtual interviews (VIs) for the 2020 residency application season were mandated as a result of the COVID-19 pandemic. We aimed to determine the perspectives of general surgery (GS) program directors (PDs) on the benefits and drawbacks of VIs. METHODS: A 14-item survey was emailed to all GS PDs from programs identified on the American Council for Graduate Medical Education website. Program directors were asked about the cost-time benefit of VIs, its ability to assess candidates, and their thoughts on the future of VIs for evaluating residency applicants. RESULTS: 60 PDs responded corresponding to a response rate of 21%. While 93% agreed/strongly agreed that VIs were less expensive, only 35% found VIs to be less time-consuming. 75% and 67%, respectively, disagreed/strongly disagreed that VIs allowed for an easier assessment of an applicant's fit, and personality and communication skills. Almost one-half of our survey respondents suggested that VIs made the selection committee rely more heavily on objective applicant data. Almost two-thirds of GS PDs suggested that they would adopt both VI and in-person interview formats for future application cycles. The median [interquartile range] cost saved through the implementation of VIs was US$ 4500 [1625 - 10 000]. CONCLUSION: Remarkably, VIs have been swiftly imbibed by all residency programs and many aspects of the VI experience were positive. While MATCH 2021 has definitely proved to be one of its kind, the implementation of VIs has been met with overall broad success and a promising future awaits this novel modality of resident selection to GME programs in the United States.

Hand Surgery in New Zealand.

Hand surgery in New Zealand has steadily grown from its origins in plastic surgery and orthopaedic surgery into its own discipline. There has been much progress and innovation in hand surgery that has originated from New Zealand and this review acknowledges the historical figures and events that have led to our present position. The current and future directions of hand surgery in our country are also discussed. As a small and remote country, we are very fortunate to have close relationships with other international hand societies. Through these relationships and the efforts of committed regional hand surgeons, the art and science of hand surgery in New Zealand continues to progress.

Impact of COVID-19 Governmental Restrictions on Emergency General Surgery Operative Volume and Severity.

BACKGROUND: To describe the effect of the COVID-19 pandemic on emergency general surgery operative volumes during governmental shutdowns secondary to the pandemic and characterize differences in disease severity, morbidity, and mortality during this time compared to previous years. METHODS: This retrospective cohort study compares patients who underwent emergency general surgery operations at a tertiary hospital from March 1st to May 31st of 2020 to 2019. Average emergent cases per day were analyzed, comparing identical date ranges between 2020 (pandemic group) and 2019 (control group). Secondary analysis was performed analyzing disease severity, morbidity, and mortality. RESULTS: From March 1st to May 31st, 2020, 2.5 emergency general surgery operations were performed on average daily compared to 3.0 operations on average daily in 2019, a significant decrease (P = .03). No significant difference was found in presenting disease severity, morbidity, or mortality between the pandemic and control groups. DISCUSSION: This study demonstrates a decrease of 65% in emergency general surgery operations during governmental restrictions secondary to the COVID-19 pandemic. This decrease in operations was not associated with worse disease severity, morbidity, or mortality.

Impact of the Coronavirus (COVID-19) Pandemic on the Care of Pediatric Acute Appendicitis.

BACKGROUND: Appendicitis is the most common abdominal surgical emergency in children. With the rise of the Coronavirus-19 pandemic, quarantine measures have been enforced to limit the viral transmission of this disease. The purpose of this study was to identify differences in the clinical presentation and outcomes of pediatric acute appendicitis during the Coronavirus-19 pandemic. METHODS: A single-institution retrospective assessment of all pediatric patients (<18 years old) with acute appendicitis from December 2019 to June 2020 was performed at a tertiary care children's hospital. Patients were divided into two groups: (1) the Pre-COVID group presented on or before March 15, 2020, and (2) the COVID group presented after March 15, 2020. Demographic, preoperative, and clinical outcomes data were analyzed. RESULTS: 45 patients were included with a median age of 13 years [IQR 9.9 - 16.2] and 35 males (78%). 28 patients were in the Pre-COVID group (62%) and 17 in the COVID group (38%). There were no differences in demographics or use of diagnostic imaging. The COVID group did have a significantly delayed presentation from symptom onset (36 vs 24 hours, P < .05), higher Pediatric Appendicitis Scores (8 vs 6, P = .003), and longer hospital stays (2.2 vs 1.3 days, P = .04). There were no significant differences for rates of re-admission, re-operation, surgical site infection, perforation, or abscess formation. CONCLUSION: During the Coronavirus-19 pandemic, the incidence of pediatric acute appendicitis was approximately 40% lower. These children presented in a delayed fashion with longer hospital stays. No differences were noted for postoperative complications.

Stereotactic Ablative radiotherapy before resection to avoid delay for early-stage lung cancer or oligometastases during the COVID-19 pandemic: Pathologic outcomes from the SABR-BRIDGE protocol.

BACKGROUND: During coronavirus disease 2019 (COVID-19)-related operating room closures, some multidisciplinary thoracic oncology teams adopted a paradigm of stereotactic ablative radiotherapy (SABR) as a bridge to surgery, an approach called SABR-BRIDGE. This study presents the preliminary surgical and pathological results. METHODS: Eligible participants from four institutions (three in Canada and one in the United States) had early-stage presumed or biopsy-proven lung malignancy that would normally be surgically resected. SABR was delivered using standard institutional guidelines, with surgery >3 months following SABR with standardized pathologic assessment. Pathological complete response (pCR) was defined as absence of viable cancer. Major pathologic response (MPR) was defined as ≤10% viable tissue. RESULTS: Seventy-two patients underwent SABR. Most common SABR regimens were 34 Gy/1 (29%, n = 21), 48 Gy/3-4 (26%, n = 19), and 50/55 Gy/5 (22%, n = 16). SABR was well-tolerated, with one grade 5 toxicity (death 10 days after SABR with COVID-19) and five grade 2-3 toxicities. Following SABR, 26 patients underwent resection thus far (13 pending surgery). Median time-to-surgery was 4.5 months post-SABR (range, 2-17.5 months). Surgery was reported as being more difficult because of SABR in 38% (n = 10) of cases. Thirteen patients (50%) had pCR and 19 (73%) had MPR. Rates of pCR trended higher in patients operated on at earlier time points (75% if within 3 months, 50% if 3-6 months, and 33% if ≥6 months; p = .069). In the exploratory best-case scenario analysis, pCR rate does not exceed 82%. CONCLUSIONS: The SABR-BRIDGE approach allowed for delivery of treatment during a period of operating room closure and was well-tolerated. Even in the best-case scenario, pCR rate does not exceed 82%.

The Impact of COVID-19 on Plastic Surgery Residents Across the World: A Country-, Region-, and Income-level Analysis.

BACKGROUND: The COVID-19 pandemic has upended graduate medical education globally. We investigated the COVID-19 impact on learning inputs and expected learning outputs of plastic surgery residents across the world. METHODS: We administered an online survey capturing training inputs before and during the pandemic and retrieved residents' expected learning outputs compared with residents who completed their training before COVID. The questionnaire reached residents across the world through the mobilization of national and international societies of plastic surgeons. RESULTS: The analysis included 412 plastic surgery residents from 47 countries. The results revealed a 44% decline (ranging from - 79 to 10% across countries) and an 18% decline (ranging from - 76 to across 151% countries) in surgeries and seminars, respectively, per week. Moreover, 74% (ranging from 0 to 100% across countries) and 43% (ranging from 0 to 100% across countries) of residents expected a negative COVID-19 impact on their surgical skill and scientific knowledge, respectively. We found strong correlations only between corresponding input and output: surgeries scrubbed in with surgical skill (ρ = -0.511 with p < 0.001) and seminars attended with scientific knowledge (ρ = - 0.274 with p = 0.006). CONCLUSIONS: Our ranking of countries based on their COVID-19 impacts provides benchmarks for national strategies of learning recovery. Remedial measures that target surgical skill may be more needed than those targeting scientific knowledge. Our finding of limited substitutability of inputs in training suggests that it may be challenging to make up for lost operating room time with more seminars. Our results support the need for flexible training models and competency-based advancement. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Operative Case Volume for Vascular Integrated Residents and Fellows Following the Elective Surgery Shutdown due to COVID-19.

In response to the COVID-19 pandemic, nonemergent surgery was postponed in efforts to limit disease spread. To determine whether these changes affected vascular integrated resident (VR) and fellow (VF) operative volume, Accreditation Council for Graduate Medical Education (ACGME) case log data was reviewed. Case volume and standard deviation for each major category was for graduates of 2020 and 2021 were compared to the year prior to the pandemic, 2019. There were only 3 significant changes when comparing 2020/2021 to the prepandemic baseline of 2019, with increase in abdominal obstructive cases for VRs (8.1 in 2021 vs 5.9 in 2019, P = .021), an increase in upper extremity cases for VFs (18.9 in 2021 from 15.8 in 2019, P = .029), and a decrease in venous cases for VFs (39.6 in 2021 from 48.4 in 2019, P = .011). Postponing nonemergent surgery did not translate to significant changes in operative cases for graduating VRs and VFs.

[Use of thoracic and lung ultrasound in general anesthesia]. / A mellkas és a tüdo ultrahangvizsgálatának szerepe az általános érzéstelenítés során.

The use of ultrasound became an essential tool in the everyday practice of anesthesiology and intensive care as an indispensable prerequisite for the precise guidance of invasive procedures and also as a point-of-care diagnostic method. Despite the limitations of imaging the lung and thoracic structures, the COVID-19 pandemic and recent advances made this technology an evolving field. The intensive therapy applies these methods with important experience for differential diagnosis and assessment of disease severity or prognosis. Minor modifications of these results make the method beneficial for anesthesia and perioperative medicine. In the present review, the authors accentuate the most important imaging artefacts of lung ultrasonography and the principles of lung ultrasound diagnostic steps. Methods and artefacts of high importance supported by evidence for the assessment of airway management, attuning of intraoperative mechanical ventilation, respiratory disorders during surgery, and postoperative prognosis are articulated. This review intends to focus on evolving subfields in which technological or scientific novelties are expected. Orv Hetil. 2023; 164(22): 864-870.

Necrotizing Skin and Soft Tissue Infection after Gluteal Augmentation in a Perioperatively Asymptomatic COVID-19 Patient-Complications of the Post-Lockdown Era? A Case Report.

Introduction: Aesthetic surgery procedures are generally done in a relatively healthy population and carry a rather low risk compared to other surgical specialties. The incidence of complications in aesthetic surgery varies greatly depending on the type, wound cleanliness regarding the anatomical site, complexity of the surgery, patient's age, and comorbidities but is generally considered low. The overall incidence of surgical site infections (SSIs) in all aesthetic surgical procedures is around 1% in most of the literature while cases of necrotizing soft tissue infections are mostly found as individual reports. In contrast, treating COVID-19 patients is still challenging with many diverse outcomes. Surgical stress and general anesthesia are known mediators of cellular immunity impairment while studies regarding COVID-19 infection unquestionably have shown the deterioration of adaptive immunity by SARS-CoV-2. Adding COVID-19 to the modern surgical equation raises the question of immunocompetence in surgical patients. The main question of the modern post-lockdown world is: what could be expected in the postoperative period of perioperatively asymptomatic COVID-19 patients after aesthetic surgery? Case report: Here, we present a purulent, complicated, necrotizing skin and soft tissue infection (NSTI) after gluteal augmentation most likely triggered by SARS-CoV-2-induced immunosuppression followed by progressive COVID-19 pneumonia in an otherwise healthy, young patient. To the best of our knowledge, this is the first report of such adverse events in aesthetic surgery related to COVID-19. Conclusion: Aesthetic surgery in patients during the incubation period of COVID-19 or in asymptomatic patients could pose a significant risk for surgical complications, including severe systemic infections and implant loss as well as severe pulmonary and other COVID-19-associated complications.

Neuraxial anesthesia for abdominal surgery, beyond the pandemic: a feasibility pilot study of 70 patients in a suburban hospital.

The aim of this study is to establish the feasibility of awake laparotomy under neuraxial anesthesia (NA) in a suburban hospital. A retrospective analysis of the results of a consecutive series of 70 patients undergoing awake abdominal surgery under NA at the Department of Surgery of our Hospital from February 11th, 2020 to October 20th, 2021 was conducted. The series includes 43 cases of urgent surgical care (2020) and 27 cases of elective abdominal surgery on frail patients (2021). Seventeen procedures (24.3%) required sedation to better control patient discomfort. Only in 4/70 (5.7%) cases, conversion to general anesthesia (GA) was necessary. Conversion to GA was not related to American Society of Anesthesiology (ASA) score or operative time. Only one of the four cases requiring conversion to GA was admitted to the Intensive Care Unit (ICU) postoperatively. Fifteen patients (21.4%) required postoperative ICU support. A statistically non-significant association was observed between conversion to GA and postoperative ICU admission. The mortality rate was 8.5% (6 patients). Five out of six deaths occurred while in the ICU. All six were frail patients. None of these deaths was related to a complication of NA. Awake laparotomy under NA has confirmed its feasibility and safety in times of scarcity of resources and therapeutic restrictions, even in the most frail patients. We believe that this approach should be considered as an useful asset, especially for suburban hospitals.

The Importance of General Surgery Residency Program's Online Presence Varies Among Applicant Groups.

INTRODUCTION: The COVID-19 pandemic necessitated an exclusively virtual 2021 residency application cycle. We hypothesized that residency programs' online presence would have increased utility and influence for applicants. METHODS: Substantial surgery residency website modifications were undertaken in the summer of 2020. Page views were gathered by our institution's information technology office for comparison across years and programs. An anonymous, voluntary, online survey was sent to all interviewed applicants for our 2021 general surgery program match. Five-point Likert-scale questions evaluated applicants' perspective on the online experience. RESULTS: Our residency website received 10,650 page views in 2019 and 12,688 in 2020 (P = 0.14). Page views increased with a greater margin compared to a different specialty residency program's (P < 0.01). From 108 interviewees, 75 completed the survey (69.4%). Respondents indicated our website was satisfactory or very satisfactory compared to other programs (83.9%), and none found it unsatisfactory. Applicants overall stated our institution's online presence impacted their decision to interview (51.6%). Programs' online presence impacted the decision to interview for nonWhite applicants (68%) but significantly less for white applicants (31%, P < 0.03). We observed a trend that those with fewer than this cohort's median interviews (17 or less) put more weight on online presence (65%), compared to those with 18 or greater interviews (35%). CONCLUSIONS: Applicants utilized program websites more during the 2021 virtual application cycle; our data show most applicants depend on institutions' websites to supplement their decision-making; however, there are subgroup differences in the influence online presence has on applicant decisions. Efforts to enhance residency webpages and online resources for candidates may positively influence prospective surgical trainees, and especially those underrepresented in medicine, to decide to interview.

Comparative evaluation using PRO of an algorithm of one-stage immediate alloplastic breast reconstruction versus two-stage reconstruction.

BACKGROUND: One-stage direct-to-implant (DTI) immediate breast reconstruction has proven to be an oncologically safe technique, but there are some conditions that do not allow its performance. The introduction of new surgical techniques and the recent COVID-19 pandemic have pushed us to introduce a breast reconstruction algorithm in our clinical practice. This allows a one-stage immediate reconstruction for all patients, regardless of their anatomical characteristics, the type of implants used, and the need for postoperative radiotherapy. METHODS: A total of 40 patients were recruited and divided into two cohorts, 20 patients underwent immediate one-stage breast reconstruction in the period between October 2019 and January 2021, and 20 patients completed the two-stage reconstructive process in the period prior to October 2019. During the follow-up at 6 months, all patients who had completed the reconstructive process filled out the Breast-Q Reconstruction Module Pre and Postoperative scales questionnaire. The outcomes of the questionnaires were compared between the two cohorts, and statistical analysis was carried out using SPSS Statistics 20 (IBM Corporation, Armonk, NY, USA). RESULTS: The analysis of patient-reported outcomes showed that patients from the one-stage group reported better outcomes in all items evaluated. We did not find statistically significant differences concerning the rate of complications and length of hospital stay between the two groups. CONCLUSIONS: The analysis of the results shows that the outcomes reported by patients who completed breast reconstruction according to our algorithm are statistically better than those with the two-stage technique.

COVID-19-induced Esophageal Necrosis Requiring Emergent Total Esophagectomy in a Vaccinated Patient.

Acute esophageal necrosis may be a potential complication of Coronavirus Disease 2019 (COVID-19). COVID-19 has been associated with a variety of sequelae, including acute respiratory distress syndrome, myocarditis, and thromboembolic events. Here, we present a case of a 43-year-old male who was admitted for acute necrotizing pancreatitis and found to have COVID-19 pneumonia. He subsequently developed acute esophageal necrosis requiring a total esophagectomy. Currently, there are at least five other reported cases of esophageal necrosis with concomitant COVID-19 infection. This case is the first requiring esophagectomy. Future studies may establish esophageal necrosis as a known complication of COVID-19.

Impact of the COVID-19 pandemic on the incidence of surgical site infection after orthopaedic surgery: an interrupted time series analysis of the nationwide surveillance database in Japan.

BACKGROUND: During the COVID-19 pandemic, hygiene awareness was increased in communities and hospitals. However, there is controversy regarding whether such circumstances affected the incidence of surgical site infections (SSIs) in the orthopaedic surgical field. AIM: To examine the impact of the COVID-19 pandemic on the incidence of SSIs after orthopaedic surgery. METHODS: The medical records of patients having undergone orthopaedic surgery were extracted from the nationwide surveillance database in Japan. The primary outcomes were the monthly incidences of total SSIs, deep or organ/space SSIs, and SSIs due to meticillin-resistant Staphylococcus aureus (MRSA). Interrupted time series analysis was conducted between pre-pandemic (January 2017 to March 2020) and pandemic (April 2020 to June 2021) periods. RESULTS: A total of 309,341 operations were included. Interrupted time series analysis adjusted for seasonality showed no significant changes in the incidence of total SSIs (rate ratio 0.94 and 95% confidence interval 0.98-1.02), deep or organ/space SSIs (0.91, 0.72-1.15), or SSIs due to MRSA (1.07, 0.68-1.68) along with no remarkable slope changes in any parameter (1.00, 0.98-1.02; 1.00, 0.97-1.02; and 0.98, 0.93-1.03, respectively). CONCLUSIONS: Awareness and measures against the COVID-19 pandemic did not markedly influence the incidence of total SSIs, deep or organ/space SSIs, or SSIs due to MRSA following orthopaedic surgery in Japan.
