COVID-19 and The Surgical Neonate

COVID-19 pandemic in 2020-2021 affected millions of people including children. Though uncommon, there are few reports of COVID in neonates also. COVID is primarily managed by pediatricians;however, they are involved when providing anesthesia to these neonates for surgery. The role of anesthetists, besides during surgery, has proven to be vital in COVID pandemic for their expertise in airway and ventilatory management, also putting them to the highest risk of exposure. Various testing methods are available, and TrueNAT and RTPCR have emerged as most reliable. Most neonates remain asymptomatic or have mild symptoms;however, RTPCR testing should be done in all at least 72 h of preoperative. Utmost care should be taken during the preoperative evaluation, and in the perioperative period, goal is to prevent transmission of COVID to noninfected HCW involved in the perioperative period, to other newborns and neonates, and also to avoid increasing the severity of the diseases in the positive neonates, while keeping in mind the vulnerability of these babies in combination with their surgical disease and the changing neonatal physiology. COVID care protocols should be followed at all times. Anesthetic considerations remain the same as described in other chapters in the book, in newborns and neonates, both term and preterm. All OT personnel need to don the PPE, which can be problematic especially for the anesthetist, as it restricts the normal unhindered movements, use of stethoscope for chest auscultation for heart rate, respiration, and ETT positioning. Hence, one needs to be very meticulous in IV line and ET placement and their securing to prevent accidental dislodging during positioning and under the drapes. All disposable and non-disposable equipment used for the covid positive baby, should be adequately treated or discarded, as the case may be, after each surgery. Only emergency surgery should be undertaken in COVID-positive neonates to prevent high postoperative morbidity and mortality. There is not much data available in neonates, and most guidelines have been introduced for children and adolescents. Neonatal care has emerged from the experience of the anesthesiologist and from extrapolation of the available pediatric guidelines. Here, we will be discussing COVID in neonates and anesthetic management in COVID-positive neonates undergoing surgery. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

ID: 219407 The Cardiac Patient and Neuromodulation, When Anticoagulation Dictates the Intervention

Introduction: Patients with cardiac comorbidities present unique challenges for undergoing interventional pain procedures. Consensus guidelines on safe anticoagulation management are categorized by procedure, patient specific bleeding risk factors, and class of anticoagulation (Table 1, Table 2).1 Specifically, some procedures occur in close proximity to the spinal cord, require large gauge needles and styletted leads, while others are in compressible locations with minimal tissue disruption. Further, pain-induced hypercoagulation increases the risk of thrombo-vascular events.1 This accentuates the importance of interdisciplinary perioperative coordination with the prescribing cardiologist. Case: A 71-year-old male with past-medical-history of CABG, bilateral femoral-popliteal bypass, atrial fibrillation on apixaban and ticagrelor, and multiple cardiac stents presented with intermittent shooting axial back pain radiating to right buttock, lateral thigh, and calf, worsened with activity. MRI demonstrated thoracic myelomalacia, multi-level lumbar disc herniation, and moderate central canal stenosis. An initial multi-model treatment approach utilizing pharmacologic agents, physical therapy, ESI's, and RFA failed to alleviate symptoms. After extensive discussion with his cardiologist, he was scheduled for a three-day SCS trial. Ticagrelor and apixaban were held throughout the 3-day trial and for 5 and 3 days prior, respectively, while ASA was maintained. Successful trial with tip placement at T6 significantly improved function and pain scores (Figure 1). Upon planned percutaneous implant, the cardiologist recommended against surgical implantation and holding anticoagulation. Alternatively, the patient underwent bilateral lumbar medial branch PNS implant with sustained improvement in lower back symptoms. However, he contracted COVID, resulting in delayed lead explanation (>60 days) without complication. Conclusion(s): Interventional pain practice advisories are well established for anticoagulation use in the perioperative period.1,2 However, there is limited high-quality research on the appropriate length to hold anticoagulation prior to surgery for high thrombotic risk patients. Collegial decision making with the cardiologist was required to avoid deleterious procedural complications. However, they may be unfamiliar with the nuances between interventions or between trial and implant. Prospective studies have shown that low risk procedures, such as the PNS, may not require holding anticoagulants.3 Other case data has demonstrated post-SCS epidural hematoma with ASA use after being held for 1-week prior to surgery. Our patient was unable to undergo SCS implant and instead elected for a lower risk procedure with excellent efficacy. 4 However, delayed PNS lead extraction due to COVID19 hospitalization presented further risk of infection and lead fracture.5 PNS may prove to be an appropriate treatment option for patients who are anticoagulated and are not SCS candidates.

Perioperative management in obstetric patients with suspected COVID-19 at Bali, Indonesia: Case series

The COVID-19 pandemic is a challenge for health practitioners, where there are many suspected and confirmed patients with COVID-19, including obstetric patients. Perioperative treatment of COVID-19 patients must be under applicable standards, for both patients and the medical personnel. Personal protective equipment is essential for health workers who treat patients with COVID-19 to prevent the transmission of the virus. The method of delivery ideally should be adapted to the clinical condition of the patient. At the same time, the management of anesthesia for patients with cesarean sections should also be adjusted to the patient's clinical condition by taking into consideration the availability of facilities and infrastructure that we have. Through this report, we want to show how we manage COVID-19 in obstetric cases using the available resources in a third-world country.Copyright © 2021 Bali Journal of Anesthesiology.

Extracorporeal membrane oxygenation for airway emergencies

Objectives: Extracorporeal membrane oxygenation (ECMO) is well established in cardiorespiratory failure. Here we report the use of ECMO in an airway emergency to provide respiratory support. Method(s): Informed consent was obtained from patient at the time of admission. Result(s): A 48-year-old with COVID-19 requiring venovenous ECMO (VVECMO) for 32 days and tracheostomy for 47 days had developed tracheal stenosis three months after tracheostomy removal, and undergone tracheal resection and reconstruction. He presented two weeks later with acute dyspnea, bloody drainage and a bulge in his neck with coughing. A computerized tomography (CT) of the cervical spine and chest showed dehiscence of the tracheal wound and a gap in the trachea. He was managed with High Flow Nasal Canula and supported on VVECMO support using 25 Fr. right femoral drainage cannula and 23 Fr. left IJ return cannula. A covered stent was placed, neck wound was irrigated and debrided. Patient was decannulated after 10 days on ECMO. Future therapeutic considerations include mediastinal tracheostomy, aortic homograft interposition of the disrupted segment of trachea with stent placement and permanent self-expandable stent with internal silicone stent. Conclusion(s): ECMO is increasingly used in complex thoracic surgery as well as in the perioperative period as salvage support. One of the areas where it has shown promising results is traumatic main bronchial rupture, airway tumor leading to severe airway stenosis, and other complex airway problems. The ease of cannulation, the technological advances and growing confidence in the management of ECMO patients are the main reasons for the expansion of ECMO use beyond conventional indications. The case described above is an example of the use of ECMO in the perioperative management of impending respiratory failure due to airway obstruction or disconnection. (Figure Presented).

Time Out: The Impact of Physician Burnout on Patient Care Quality and Safety in Perioperative Medicine.

Perioperative care delivery is a patient-centered, multidisciplinary process. It relies heavily on synchronized teamwork from a well-coordinated team. Perioperative physicians-surgeons and anesthesiologists-face enormous challenges in surgical care delivery due to changing work environments, post-COVID consequences, shift work disorder, value conflict, escalating demands, regulatory complexity, and financial uncertainties. Physician burnout in this working environment has become increasingly prevalent. It is not only harmful to physicians' health and well-being, but it also affects the quality and safety of patient care. Additionally, the economic costs associated with physician burnout are untenable due to the high turnover rate, high recruitment expenses, and potential early permanent exit from medical practice. In this deteriorating environment of unbalanced physician supply/demand, recognizing, managing, and preventing physician burnout may help preserve the system's most valuable asset and contribute to higher quality and safety of patient care. Leaders in government agencies, health care systems, and organizations must work together to re-engineer the health care system for better physicians and patient care.

Preoperative triage to detect SARS-CoV-2 infection in surgical patients: lessons learned for resuming surgery.

PURPOSE: To define the impact of the COVID-19 outbreak on hospital surgical activity and assess the incidence of perioperative COVID-19 within two protocolized screening pathways for elective and non-elective surgery. METHODS: We conducted a prospective cohort study of adults undergoing surgery during the COVID-19 outbreak. The elective pathway included telephone surveys and a quantitative polymerase-chain-reaction test (RT-PCR) only for patients who were asymptomatic and at low risk of infection. Only patients with negative screening underwent surgery. In the non-elective pathway, preoperative screening was performed during the hospital admission. RESULTS: Among 835 patients considered for the elective pathway, 725 had negative RT-PCR results and underwent surgery. This reflects an 83% reduction in surgical activity from 2019. Moreover, 596 patients underwent non-elective surgery, representing a 28% reduction. Preoperatively, 39 patients (6.5%) tested positive for SARS-CoV-2 and underwent surgery through the non-elective pathway, vs. none in the elective pathway (p < 0.001). Postoperatively, 1.4% of elective surgery patients and 2.2% of non-elective surgery patients tested positive (p > 0.05). Mortality was higher in non-elective surgery (0.6% vs. 2.9%, p < 0.001) and in patients with COVID-19 (0% vs. 14%, p < 0.001). CONCLUSIONS: The low incidence of COVID-19 in elective surgeries during the outbreak demonstrates the importance and effectiveness of preoperative screening, combining surveys and RT-PCR.

Pre-assessment and management of long COVID patients requiring elective surgery: challenges and guidance.

Whilst most patients infected with COVID-19 make a full recovery, around 1 in 33 patients in the UK report ongoing symptoms post-infection, termed 'long COVID'. Studies have demonstrated that infection with early COVID-19 variants increases postoperative mortality and pulmonary complications for around 7 weeks after acute infection. Furthermore, this increased risk persists for those with ongoing symptoms beyond 7 weeks. Patients with long COVID may therefore also be at increased postoperative risk, and despite the significant prevalence of long COVID, there are minimal guidelines on how best to assess and manage these patients perioperatively. Long COVID shares several clinical and pathophysiological similarities with conditions such as myalgic encephalitis/chronic fatigue syndrome and postural tachycardia syndrome; however, there are no current guidelines for the preoperative management of these patients to help develop something similar for long COVID patients. Developing guidelines for long COVID patients is further complicated by its heterogenous presentation and pathology. These patients can have persistent abnormalities on pulmonary function tests and echocardiography 3 months after acute infection, correlating with a reduced functional capacity. Conversely, some long COVID patients can continue to experience symptoms of dyspnoea and fatigue despite normal pulmonary function tests and echocardiography, yet demonstrating significantly reduced aerobic capacity on cardiopulmonary exercise testing even a year after initial infection. How to comprehensively risk assess these patients is therefore challenging. Existing preoperative guidelines for elective patients with recent COVID-19 generally focus on the timing of surgery and recommendations for pre-assessment if surgery is required before this time interval has elapsed. How long to delay surgery in those with ongoing symptoms and how to manage them perioperatively are less clear. We suggest that multidisciplinary decision-making is required for these patients, using a systems-based approach to guide discussion with specialists and the need for further preoperative investigations. However, without a better understanding of the postoperative risks for long COVID patients, it is difficult to obtain a multidisciplinary consensus and obtain informed patient consent. Prospective studies of long COVID patients undergoing elective surgery are urgently required to help quantify their postoperative risk and develop comprehensive perioperative guidelines for this complex patient group.

The Case for Improvement in Perioperative Medicine

Health care is undergoing major transformation with a shift from fee-for-service care to fee-for-value. Although there have been substantial advances in anesthesia care, perioperative complications and mortality after surgery remain a key concern. The impact of the COVID-19 pandemic on surgical and procedural practices further highlights the urgency and need for an expanded role of perioperative medicine to impact system improvement. The surgical experience is frequently the first touchpoint to reengage the patient in their own health care. Some of the key interventions that are being effectively instituted by the anesthesiologists include proactive engagement in preoperative optimization of patient's health;personalization and standardization of care delivery by segmenting patients based on their complexity and risk;and implementation of best practices that are data-driven and evidence-based and provide structure that allow patients to return to their optimal state of functional, cognitive, and psychological health. Through collaborative relationships with other perioperative stakeholders, anesthesiologists can consolidate their role as clinical leaders driving value-based care and healthcare transformation in the best interests of our patients. © 2023 Elsevier Inc.

Development and prospect of clinical research on lung transplantation in post-COVID-19 era

Lung transplantation has been advanced for nearly half a century around the globe, and it has been developed rapidly for over 20 years in China. The field of lung transplantation in China has been gradually integrated into the international community. The outbreak of novel coronavirus pneumonia (COVID-19) in 2020 brought big challenges, as well as diverted the worldwide attention to the development of lung transplantation in China, accelerating international communication and cooperation. With the steadily deepening of clinical and basic research on lung transplantation for severe cases of COVID-19, organ transplant physicians have deepened the understanding and thinking of the maintenance of donors, selection of elderly and pediatric candidates, and perioperative management of recipients, as the future perspective of lung transplantation in China. For interdisciplinary research related to lung transplantation, it is necessary to carry out multi-center clinical trials with qualified study design and constantly promote the theoretic and practical innovation.Copyright © 2021 The authors.

Equity and Perioperative Care

The COVID-19 pandemic, with its disproportionate impact on historically marginalized populations, highlighted underlying inequities in society that can lead to disparate health outcomes and increased attention to the need to address health disparities. Although different countries may have different issues relating to health disparities, this chapter describes approaches that can be broadly applied to improve health equity and reduce disparities in perioperative care. © 2023 Elsevier Inc.

Overview, Updates, and New Topics in Perioperative Care

The utilization of perioperative care within a healthcare system holds a critical role not only at the individual patient level but also at the scale of the hospital system. Perioperative care encompasses the care of a patient before, during, and after undergoing a surgical procedure. The aim of this chapter is to discuss the components of perioperative care, the methods for risk assessment of predictable complications and outcomes, and optimization of a patient's chronic medical conditions. The risk assessment process involves collecting information about surgical and anesthetic factors in conjunction with patient factors. This includes anesthesia type and the extent and duration of the surgical procedure. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Abstract Introduction: The current situation caused by COVID-19 demands the implementation of new techniques in anesthetic management and pre-existing risks in surgical services. Objective: to identify the anesthetic considerations for patients with COVID-19 to suggest interventions in the surgical area. Methodology: Integrative review of descriptive scope in conjunction with compliance with the methodological steps of Whittemore-Knafl and the PRISMA parameters. The search was performed in the following databases: PubMed, VHL, Coronavirus Research Database, SCOPUS, Elsevier, and SAGE. A total of 953 articles were obtained, which together with a critical analysis by CASPe, met the established inclusion and exclusion criteria. Results: Twenty-seven articles classified as: selection criteria for anesthetic techniques; general anesthesia and the use of specific medications for anesthetic management that reduce cough and prevent the release of aerosols; airway management to avoid failed intubations; regional anesthesia and nursing considerations in the preparation of elements and devices prior to the patient's admission to the operating room; identification and follow-up of symptomatic and asymptomatic patients during the perioperative process. Conclusion: Regarding the anesthetic technique, it is important to prioritize the use, as far as possible, of ultrasound-guided regional anesthesia. If general anesthesia is required, it is advisable to maintain precautions to prevent infection with the virus. For nursing, the role in preparing a safe surgical environment, knowledge of the anesthetic technique used and individualized care according to the required needs stand out.

Patient and Provider Satisfaction With Telehealth Preanesthesia Examinations.

PURPOSE: Telehealth has become commonplace in many healthcare systems across the United States. Due to the COVID-19 pandemic, a large academic medical center in the southeast USA has increased the use of telehealth in the anesthesia department to complete preanesthetic assessments before the patient's surgery. This has allowed high-risk patient populations to limit potential exposure to COVID-19 and limit the financial burden of traveling from neighboring counties to complete their preanesthetic assessment in person. The purpose of this quality improvement project was to evaluate the effectiveness of a preanesthetic assessment via telehealth among patients undergoing anesthesia. DESIGN: A quality improvement project. METHODS: Two separate surveys assessing patient and provider satisfaction with telehealth preanesthesia assessments were developed. Patients undergoing anesthesia at the medical center completed a telehealth preanesthesia assessment and received a satisfaction survey via email post-procedure. Certified registered nurse anesthetists (CRNAs) who cared for patients that completed a telehealth preanesthesia assessment also received an emailed satisfaction survey. FINDINGS: Results demonstrate high satisfaction scores for both patients and providers. CONCLUSIONS: Current telehealth preanesthetic assessments prompt high satisfaction scores, supporting continued, and expanded use.

Surgical site infections during the COVID-19 era: A retrospective, multicenter analysis.

BACKGROUND: Surgical site infections (SSIs) are an undesired perioperative outcome. Recent studies have shown increases in hospital acquired infections during the coronavirus disease 2019 (COVID-19) pandemic. The objective of this study was to evaluate postoperative SSIs in the COVID-19-era compared to a historical cohort at a large, multicenter, academic institution. METHODS: A retrospective review of all patients who underwent National Health and Safety Network (NHSN) inpatient surgical procedures between January 1, 2018 and December 31, 2020. Patients from the COVID-19-era (March-December 2020) were compared and matched 1:1 with historical controls (2018/2019) utilizing the standardized infection ratio (SIR) to detect difference. RESULTS/DISCUSSION: During the study period, 29,904 patients underwent NHSN procedures at our institution. When patients from the matched cohort (2018/2019) were compared to the COVID-19-era cohort (2020), a decreased risk of SSI was observed following colorectal surgery (RR = 0.94, 95% CI [0.65, 1.37], P = .76), hysterectomy (RR = 0.88, 95% CI [0.39, 1.99], P = .75), and knee prothesis surgery (RR = 0.95, 95% CI [0.52, 1.74], P = .88), though not statistically significant. An increased risk of SSI was observed following hip prosthesis surgery (RR 1.09, 95% CI [0.68, 1.75], P = .72), though not statistically significant. CONCLUSIONS: The risk of SSI in patients who underwent NHSN inpatient surgical procedures in 2020 with perioperative COVID-19 precautions was not significantly different when compared to matched controls at our large, multicenter, academic institution.

The Impact of the COVID-19 Pandemic on Emergency Surgical Operations in State Hospitals in Turkey: A Retrospective and Descriptive Study

Aim: Emergency surgery can be defined as surgical interventions and operations necessary to deal with an acute threat to life, organ, limb, or tissue. Our study examined the impact of the Coronavirus disease-2019 (COVID-19) pandemic on emergency surgical operations (ESOs) performed in state hospitals in Turkey. Materials and Methods: In this national, retrospective, and descriptive study, ESOs performed in 2nd and 3rd-level state hospitals in Turkey in 2021 were recorded for the study. ESOs performed in 2019 were taken as the control group, and the changes between the two groups were examined. Results: A total of 1,822,075 ESOs were included in the analysis. There was a 7.6% decrease in ESOs in 2021 compared to 2019. In both 2019 and 2021, cesarean section, surgical treatment of upper/lower extremity fractures and dislocations, and cholecystectomy were the most frequently performed ESOs. An increase in the number of ESOs in 2021 compared to 2019 was observed only in the urology department (7.1%) and orthopedics and traumatology department (2.7%). The surgical departments with the greatest decreases were neurosurgery (-28.1%), Otolaryngology-Head and Neck Surgery (-27.7%), and thoracic surgery (-20.9%) Conclusion: During the COVID-19 pandemic, the number of ESOs performed in the 2nd and 3rd-level state hospitals in Turkey decreased compared with the previous year.

Pulmonary Complications and Mortality in Patients with SARS-CoV-2 Undergoing Elective and Emergent Hand Surgery

Background Patients acutely infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may have increased risk for postsurgical pulmonary complications and mortality, particularly with general anesthesia. Surgery is often delayed to mitigate risk;however, excessive delays may result in morbidity. Optimal criteria for delaying surgery in patients with or without symptoms are unknown. This study aimed to evaluate any complications following hand surgery in patients testing positive for SARS-CoV-2.Methods We retrospectively reviewed patients with a positive polymerase chain reaction test within 60 days before or after hand surgery between March 31, 2020 and March 31, 2021. Patients were telephoned also to supplement records. Type of surgery, type of anesthesia, comorbidities, timing of surgery, onset of symptoms, and complications were recorded.Results We identified 21 patients undergoing 26 procedures, of which 21 (81%) were emergency procedures and 5 (19%) were elective. Mean age was 37 years (range: 17-71). General anesthesia was used in 88% of cases, with mean duration of 110 minutes. SARS-CoV-2 was diagnosed on average 6 days preoperatively (range: 39 days preop-14 days postop). Positive tests were usually identified preoperatively (50%), versus day-of-surgery (25%) or postoperatively (25%). Patients were symptomatic in only 27% of cases, and completely asymptomatic in 73%. No asymptomatic patients developed complications. One patient suffered a fracture malunion after delayed surgery. Pulmonary complications were noted in 3 patients;all had prior pulmonary disease and underwent emergency surgeries under general anesthesia. Overall mortality rate was 0%.Conclusion Pulmonary complications and mortality are low following hand surgery in asymptomatic patients with a positive SARS-CoV-2 test.

Practice Changing Updates in Perioperative Medicine Literature 2022. A Systematic Review.

Perioperative medicine is a rapidly growing multidisciplinary field with significant advances published each year. In this review, we highlight important perioperative publications in 2022. A multi-database literature search from January to December of 2022 was undertaken. Original research articles, systematic reviews, meta-analyses, and guidelines were included. Abstracts, case reports, letters, protocols, pediatric and obstetric articles, and cardiac surgery literature were excluded. Two authors reviewed each reference using the Distiller SR systematic review software (Evidence Partners Inc., Ottawa, Ont, Canada). A modified Delphi technique was used to identify 8 practice-changing articles. We identified another 10 articles for tabular summaries. We highlight why these articles have the potential to change clinical perioperative practice and areas where more information is needed.

Give full play to the role of pharmacists in the safety management of direct oral anticoagulants.

Direct oral anticoagulants (DOACs) are recommended as first-line therapy in patients with atrial fibrillation and venous thromboembolic diseases in relevant guidelines at home and abroad. Compared with warfarin, DOACs have relatively fixed dose, fewer drug interactions, and no need of routine therapeutic drug monitoring in clinic. DOACs bring much convenience to anticoagulant therapy, but they also raise a series of new medication safety challenges. Pharmacists should ensure the safe use of DOAC through improving corresponding pharmaceutical care mechanism, such as assisting doctors to improve the suitability of dose in prescription, standardizing laboratory monitoring process, setting up early warning of potential drug interaction, and strengthening anticoagulant conversion and perioperative anticoagulant therapy management. In the post-coronavirus disease 2019 era, incorporating DOACs into the standardized manage- ment at anticoagulation clinics is an important work extension of the traditional anticoagulation clinics and may reduce the risk of exposure to the novel coronavirus. In addition, considering the limit in labour and work energy of clinical pharmacists, the application of DOAC-related clinical decision support system may help improve the appropriateness of prescription and reduce the adverse drug events.Copyright © 2020 Chinese Medical Journals Publishing House Co.Ltd.

Higher Complication Rate in COVID-19 Recovered Patients Undergoing Primary Total Joint Arthroplasty.

BACKGROUND: There is limited data reviewing complication risks associated with total joint arthroplasty (TJA) after recovering from COVID-19. This study evaluated complications within 90 days of TJA in patients who had a COVID-19 diagnosis at varying intervals prior to surgery versus a non-COVID-19 cohort. METHODS: A large national database was used to identify patients diagnosed with COVID-19 in the six months prior to total hip arthroplasty (THA) or total knee arthroplasty. The incidence of complications within 90 days of surgery was recorded and compared to a COVID-19 negative control group matched 1:3 for age range in 5-year intervals, Charlson Comorbidity Index, and sex. There were 7,780 patients included in the study; 5,840 (75.1%) never diagnosed with COVID-19, 1,390 (17.9%) who had a COVID-19 diagnosis 0 to 3 months prior to surgery, and 550 (7.1%) who had a COVID-19 diagnosis 3 to 6 months prior to surgery. RESULTS: When compared to their COVID negative controls, patients who had a COVID-19 diagnosis 0 to 3 months prior to surgery had significantly higher rates of readmission (14.0 versus 11.1%, P = .001), pneumonia (2.2 versus 0.7%, P < .001), deep vein thrombosis (DVT) (3.3 versus 1.9%, P = .001), kidney failure (2.4 versus 1.4%, P = .006), and acute respiratory distress syndrome (1.4 versus 0.7%, P = .01). Patients who had a COVID-19 diagnosis 3 to 6 months prior to surgery had significantly higher rates of pneumonia (2.0 versus 0.7%, P = .002) and DVT (3.6 versus 1.9%, P = .005) when compared to their COVID negative controls. CONCLUSION: Patients diagnosed with COVID-19 within three months prior to TJA have an increased risk of 90-day postoperative complications. Risk for pneumonia and DVT remains elevated even when surgery was performed as far as 3 to 6 months after COVID-19 diagnosis.
