Integration of smartphone-based mobile health technology into perioperative care-the patient's perspective.

Although numerous use cases demonstrate the value of mobile health technology, there is limited knowledge regarding patient perceptions of such technology, which may explain the lack of broader implementation of mobile health technology. Achieving meaningful, sustained, and equitable use of mobile health technology in surgery necessitates a human-centered design approach with consideration given to end users. This review article draws on evidence from prior qualitative studies of both surgeons and patients to make recommendations that may assist health care systems in realizing the full potential of mobile health technology for delivering high-quality, patient-centered surgical care.

A Pilot Study Using Machine Learning Algorithms and Wearable Technology for the Early Detection of Postoperative Complications After Cardiothoracic Surgery.

OBJECTIVE: To evaluate whether a machine learning algorithm (i.e. the "NightSignal" algorithm) can be used for the detection of postoperative complications prior to symptom onset after cardiothoracic surgery. SUMMARY BACKGROUND DATA: Methods that enable the early detection of postoperative complications after cardiothoracic surgery are needed. METHODS: This was a prospective observational cohort study conducted from July 2021 to February 2023 at a single academic tertiary care hospital. Patients aged 18 years or older scheduled to undergo cardiothoracic surgery were recruited. Study participants wore a Fitbit watch continuously for at least 1 week preoperatively and up to 90-days postoperatively. The ability of the NightSignal algorithm-which was previously developed for the early detection of Covid-19-to detect postoperative complications was evaluated. The primary outcomes were algorithm sensitivity and specificity for postoperative event detection. RESULTS: A total of 56 patients undergoing cardiothoracic surgery met inclusion criteria, of which 24 (42.9%) underwent thoracic operations and 32 (57.1%) underwent cardiac operations. The median age was 62 (IQR: 51-68) years and 30 (53.6%) patients were female. The NightSignal algorithm detected 17 of the 21 postoperative events a median of 2 (IQR: 1-3) days prior to symptom onset, representing a sensitivity of 81%. The specificity, negative predictive value, and positive predictive value of the algorithm for the detection of postoperative events were 75%, 97%, and 28%, respectively. CONCLUSIONS: Machine learning analysis of biometric data collected from wearable devices has the potential to detect postoperative complications-prior to symptom onset-after cardiothoracic surgery.

Haemosuccus pancreaticus and seven episodes of recurrent unlocalised upper gastrointestinal bleeding.

Upper gastrointestinal (GI) bleeding is a common medical condition that results in extensive morbidity and mortality, as well as substantial healthcare costs. While there is variation among society and consensus guidelines, the approaches to assessment and evaluation are generally consistent. Our case describes a man in his 40s who presented with seven episodes of recurrent upper GI bleeding over 2 years secondary to haemosuccus pancreaticus. While rare, this case study highlights key principles to the initial diagnostic approach that, in appropriate clinical contexts, should be applied to patients with unlocalised upper GI bleeding. We further perform a complete systematic review of similar cases available in PubMed (36 patients in 24 case reports) to further refine these diagnostic principles.

Real-life Clinical Outcomes of Low-voltage Isolation and Spatiotemporal Dispersion Ablation Strategies for Persistent Atrial Fibrillation.

Multiple techniques have been developed in addition to pulmonary vein isolation (PVI) to improve the outcomes of catheter ablation in patients with persistent atrial fibrillation (AF). We sought to evaluate the long-term efficacy of alternative techniques used in our laboratory for the treatment of persistent AF, including spatiotemporal dispersion (SD) and low-voltage isolation (LVI). Consecutive patients with persistent AF who underwent catheter ablation with the studied techniques between July 2016 and December 2019 were included in the study. PVI alone was compared with PVI plus SD and PVI plus LVI in terms of long-term freedom from atrial tachycardia (AT) and AF recurrence. Follow-up data were obtained from clinical records and hospital visits, which included a 7-day Holter monitor and electrocardiograms. The study was approved by the institutional review board of Rhode Island Hospital. A total of 382 patients underwent catheter ablation at our institution during the study period. One hundred seventy-two patients had paroxysmal AF and were excluded from the study. The remaining 210 patients had persistent AF and were included in the study. One hundred and three patients underwent PVI alone, while 48 had the addition of LVI and 59 had SD. Additionally, freedom from AT/AF recurrence at 18 months was 68% in the group that underwent LVI, 49% in the SD group, and 40% in the group that underwent PVI alone (log-rank P = .014). Freedom from AF recurrence was 74% in the LVI group, 71% in the SD group, and 43% in the PVI-alone group (log-rank P = .002). On multivariate Cox regression, LVI and left atrial size were found to be independent predictors of recurrence (hazard ratio, 0.39; 95% confidence interval, 0.206-0.760; P = .005 and hazard ratio, 1.4; 95% confidence interval, 1.105-1.923; P = .008, respectively). LVI and SD in addition to PVI were associated with greater freedom from AT/AF recurrence at 18 months compared to PVI alone.

A national survey of occupational musculoskeletal injuries in cardiothoracic surgeons.

OBJECTIVE: There is growing concern that surgeons are at increased risk for work-related orthopedic injuries due to poor ergonomics. We conducted a survey of North American cardiothoracic surgeons to evaluate the prevalence of occupational injury, as well as perceptions and use of ergonomic techniques. METHODS: Cardiothoracic surgeons identified through the Cardiothoracic Surgery Network were asked to complete a 33-question survey assessing their musculoskeletal health, as well as their perceptions and use of ergonomic techniques in the operating room and office. RESULTS: Among 600 cardiothoracic surgeons, the prevalence of occupational musculoskeletal injuries was 64%, with 30% of affected surgeons requiring time away from work and 20% requiring surgery or the use of narcotics. Cervical spine injury (35%, n = 216) was the most common injury due to operating, followed by lumbar spine injury (30%, n = 180). In multivariable-adjusted analysis, cardiac surgeons were more likely than thoracic surgeons to experience occupational musculoskeletal injuries (adjusted odds ratio, 1.8 [1.2-2.8], P < .01). Notably, 90% of surgeons (n = 536) reported thinking that their institution did not provide sufficient ergonomics education or support, and only 35% (n = 205) thought that the cardiothoracic surgical community is supportive of implementing ergonomics techniques in the operating room and office. CONCLUSIONS: In this survey analysis, cardiothoracic surgeons reported experiencing work-related orthopedic injuries at an alarmingly high rate, leading to significant time away from work and for many to retire from surgery over a decade early. These findings underline a critical need for institutions to prioritize ergonomics education and implement ergonomics-directed techniques in the operating room and office.

Efficacy and Safety of Supraclavicular Thoracic Outlet Decompression.

OBJECTIVES: We aimed to report efficacy, safety, and health-related quality of life (HRQoL) outcomes of a multidisciplinary treatment approach including supraclavicular thoracic outlet decompression among patients with thoracic outlet syndrome (TOS). BACKGROUND: TOS is a challenging condition where controversy remains in diagnosis and treatment, primarily given a lack of data exploring various treatment approaches and associated patient outcomes. METHODS: Patients who underwent unilateral, supraclavicular thoracic outlet decompression, or pectoralis minor tenotomy for neurogenic, venous, or arterial TOS were identified from a prospectively maintained database. Demography, use of preoperative botulinum toxin injection, and participation in multidisciplinary evaluation were measured. The primary endpoints were composite postoperative morbidity and symptomatic improvement compared with baseline. RESULTS: Among 2869 patients evaluated (2007-2021), 1032 underwent surgery, including 864 (83.7%) supraclavicular decompressions and 168 (16.3%) isolated pectoralis minor tenotomies. Predominant TOS subtypes among surgical patients were neurogenic (75.4%) and venous TOS (23.4%). Most patients (92.9%) with nTOS underwent preoperative botulinum toxin injection; 56.3% reported symptomatic improvement. Before surgical consultation, few patients reported participation in physical therapy (10.9%). The median time from first evaluation to surgery was 136 days (interquartile range: 55, 258). Among 864 patients who underwent supraclavicular thoracic outlet decompression, complications occurred in 19.8%; the most common complication was chyle leak (8.3%). Four patients (0.4%) required revisional thoracic outlet decompression. At a median follow-up of 420 days (interquartile range: 150, 937) 93.3% reported symptomatic improvement. CONCLUSION: Based on low composite morbidity, need for very few revisional operations, and high rates of symptomatic improvement, a multidisciplinary treatment approach including primarily supraclavicular thoracic outlet decompression is safe and effective for patients with TOS.

Recurrence After Complete Resection for Non-Small Cell Lung Cancer in the National Lung Screening Trial.

BACKGROUND: The objective of this study was to evaluate patterns, predictors, and long-term outcomes of recurrent disease after complete resection for early-stage non-small cell lung cancer (NSCLC) using the National Lung Screening Trial (NLST). METHODS: The frequency of recurrence in patients with pathologic stage I-II NSCLC who underwent complete resection (lobectomy or bilobectomy) in the NLST was evaluated. Predictors of increased risk of recurrence were assessed by Fine-Gray competing risks regression. RESULTS: Of the 497 patients meeting study inclusion criteria, 94 experienced a recurrence-a rate of 4.9 (95% CI, 4.0-6.0) per 100 person-years. The 5-year cumulative incidence of recurrence was 20.1% (95% CI, 16.5%-23.9%). Most patients experienced recurrences at distant sites alone (n = 47 [50.0%]) or at both locoregional and distant sites (n = 30 [31.9%]). The median time from resection to recurrence was 18.8 (10.6-30.7) months. The incidence rate of recurrence was significantly lower among patients with lung cancer detected by low-dose computed tomography screening during one of the three screening rounds of the NLST when compared with patients with lung cancer detected by chest radiography screening and patients with lung cancer not detected by any form of screening (ie, those diagnosed after a negative or missed screening exam and those diagnosed during follow-up after the three screening rounds of the NLST were completed) (P < .001). Median survival (from the date of recurrence) of patients with pathologic stage I and stage II disease who had recurrences at locoregional, distant, or both sites was 63.0, 23.1, and 9.8 months and 28.9, 8.7, and 10.2 months, respectively. CONCLUSIONS: In this analysis of NLST participants with completely resected stage I-II NSCLC, the 5-year cumulative incidence of recurrence was 20%. Nearly 82% of recurrences were at distant sites and associated with poor survival.

Surgical Approach to Esophagectomy Post CheckMate 577: Do Lymph Nodes Matter if Everyone Gets Adjuvant Immunotherapy?

Following the results of the CheckMate 577 trial, the Food and Drug Administration approved adjuvant immune checkpoint inhibitor therapy for patients with locally advanced esophageal cancer without a pathologic complete response following neoadjuvant chemoradiotherapy and esophagectomy. This innovation in systemic therapy has rekindled the debate around the clinical value of an extended lymphadenectomy at the time of esophagectomy. In this article, we provide a review of the oncologic principles and potential risks and benefits of extended lymphadenectomy at the time of esophagectomy with acknowledgments to current and forthcoming innovations in thoracic surgery.

Postoperative radiotherapy with modern techniques does not improve survival for operable stage IIIA-N2 non-small cell lung cancer.

OBJECTIVES: This study aims to evaluate whether postoperative radiotherapy using newer techniques (intensity-modulated radiotherapy [IMRT]) is associated with improved survival for patients with stage IIIA-N2 non-small cell lung cancer (NSCLC) who underwent complete resection. METHODS: The overall survival of patients with stage IIIA-N2 NSCLC who received postoperative IMRT versus no postoperative IMRT following induction chemotherapy and lobectomy in the National Cancer Database from 2010-2018 was assessed via Kaplan-Meier analysis, Cox proportional hazards analysis and propensity score-matched analysis. Additional survival analyses were also conducted in patients with completely resected stage IIIA-pN2 NSCLC who had upfront lobectomy (without induction therapy) followed by adjuvant chemotherapy alone or adjuvant chemotherapy with postoperative IMRT. Only patients receiving IMRT, which is a newer, more conformal radiotherapy technique, were included. Patients with positive surgical margins were excluded. RESULTS: A total of 3203 patients with stage IIA-N2 NSCLC who underwent lobectomy were included. Five hundred eighty-eight (18.4%) patients underwent induction chemotherapy followed by lobectomy, and 2615 (82%) underwent lobectomy followed by chemotherapy. In unadjusted, multivariable-adjusted, and propensity score--matched analyses, there were no significant differences in overall survival between the patients who also received postoperative IMRT versus those who did not. CONCLUSIONS: In this national analysis, the use of postoperative IMRT was not associated with improved survival in patients with completely resected stage IIIA-N2 NSCLC with or without induction chemotherapy.

Perceptions of Mobile Health Technology in Elective Surgery: A Qualitative Study of North American Surgeons.

OBJECTIVES: To explore the surgeon-perceived added value of mobile health technologies (mHealth), and determine facilitators of and barriers to implementing mHealth. BACKGROUND: Despite the growing popularity of mHealth and evidence of meaningful use of patient-generated health data in surgery, implementation remains limited. METHODS: This was an exploratory qualitative study following the Consolidated Criteria for Reporting Qualitative Research. Purposive sampling was used to identify surgeons across the United States and Canada. The Consolidated Framework for Implementation Research informed development of a semistructured interview guide. Video-based interviews were conducted (September-November 2020) and interview transcripts were thematically analyzed. RESULTS: Thirty surgeons from 8 specialties and 6 North American regions were interviewed. Surgeons identified opportunities to integrate mHealth data pre- operatively (eg, expectation-setting, decision-making) and during recovery (eg, remote monitoring, earlier detection of adverse events) among higher risk patients. Perceived advantages of mHealth data compared with surgical and patient-reported outcomes included easier data collection, higher interpretability and objectivity of mHealth data, and the potential to develop more patientcentered and functional measures of health. Surgeons identified a variety of implementation facilitators and barriers around surgeon- and patient buy-in, integration with electronic medical records, regulatory/reimbursement concerns, and personnel responsible for mHealth data. Surgeons described similar considerations regarding perceptions of mHealth among patients, including the potential to address or worsen existing disparities in surgical care. CONCLUSIONS: These findings have the potential to inform the effective and equitable implementation of mHealth for the purposes of supporting patients and surgical care teams throughout the delivery of surgical care.

Open, Video- and Robot-Assisted Thoracoscopic Lobectomy for Stage II-IIIA Non-Small Cell Lung Cancer.

BACKGROUND: This study compares the short- and long-term outcomes of open vs robotic vs video-assisted thoracoscopic surgery (VATS) lobectomy for stage II-IIIA non-small-cell lung cancer (NSCLC). METHODS: Outcomes of patients with stage II-IIIA NSCLC (excluding T4 tumors) who received open and minimally invasive surgery (MIS) lobectomy in the National Cancer Database from 2010 to 2017 were assessed using propensity score-matched analysis. RESULTS: A propensity score-matched analysis of 4652 open and 4652 MIS patients demonstrated a decreased median length of stay associated with MIS compared with open lobectomy (5 vs 6 days; P < .001). There were no significant differences in 30-day mortality, 30-day readmission, or overall survival between the open and MIS groups. A propensity score-matched analysis of 1186 VATS and 1186 robotic patients showed that compared with VATS, the robotic approach was associated with no significant differences in 30-day mortality, 30-day readmission, and overall survival. However, the robotic group had a decreased median length of stay compared with VATS (4 vs 5 days; P < .001). The conversion rate was also significantly lower for robotic compared with VATS lobectomy (8.9% vs 15.9%, P < .001). CONCLUSIONS: No significant differences were found in long-term survival between open and MIS lobectomy and between VATS and robotic lobectomy for stage II-IIIA NSCLC. However, the MIS approach was associated with a decreased length of stay compared with the open approach. The robotic approach was associated with decreased length of stay and decreased conversion rate compared with the VATS approach.

Enhancing Patient-Centered Surgical Care With Mobile Health Technology.

From smartphones or wearables to portable physiologic sensors and apps, healthcare is witnessing an exponential growth in mHealth-digital health tools used to support medical and surgical care, as well as public health. In surgery, there is interest in harnessing the capabilities of mHealth to improve the quality of patient-centered care delivery. Digitally delivered surveys have enhanced patient-reported outcome measurement and patient engagement throughout care. Wearable devices and sensors have allowed for the assessment of physical fitness before surgery and during recovery. Smartphone-based digital phenotyping has introduced novel methods of integrating multiple data streams (accelerometer, global positioning system, call and text logs) to create multidimensional digital health footprints for patients following surgery. Yet, with all the technological sophistication and 'big data' mHealth provides, widespread implementation has been elusive. Do clinicians and patients find these data valuable or clinically actionable? How can mHealth become integrated into the day-to-day workflows of surgical systems? Do these data represent opportunities to address disparities of care or worsen them? In this review, we discuss experiences and future opportunities to use mHealth to enhance patient-centered surgical care.

Smartphone-based Assessment of Preoperative Decision Conflict and Postoperative Physical Activity Among Patients Undergoing Cancer Surgery: A Prospective Cohort Study.

OBJECTIVE: To determine the prevalence of clinically significant decision conflict (CSDC) among patients undergoing cancer surgery and associations with postoperative physical activity, as measured through smartphone accelerometer data. BACKGROUND: Patients with cancer face challenging treatment decisions, which may lead to CSDC. CSDC negatively affects patient-provider relationships, psychosocial functioning, and health-related quality of life; however, physical manifestations of CSDC remain poorly characterized. METHODS: Adult smartphone-owners undergoing surgery for breast, skin-soft-tissue, head-and-neck, or abdominal cancer (July 2017-2019) were approached. Patients downloaded the Beiwe application that delivered the Decision Conflict Scale (DCS) preoperatively and collected smartphone accelerometer data continuously from enrollment through 6 months postop-eratively. Restricted-cubic-spline regression, adjusting for a priori potential confounders (age, type of surgery, support status, and postoperative complications) was used to determine trends in postoperative daily physical activity among patients with and without CSDC (DCS score >25/100). RESULTS: Among 99 patients who downloaded the application, 85 completed the DCS (86% participation rate). Twenty-three (27%) reported CSDC. These patients were younger (mean age 48.3 years [standard deviation 14.2]-vs-55.0 [13.3], P = 0.047) and more frequently lived alone (22%-vs-6%, P = 0.042). There were no differences in preoperative physical activity (115.4 minutes [95%CI 90.9, 139.9]-vs-110.8 [95%CI 95.7, 126.0], P = 0.753). Adjusted postoperative physical activity was lower among patients reporting CSDC at 30 days (difference 33.1 minutes [95%CI 5.93,60.2], P = 0.017), 60 days 35.5 [95%CI 8.50, 62.5], P = 0.010 and 90 days 31.8 [95%CI 5.44, 58.1], P = 0.018 postoperatively. CONCLUSIONS: CSDC was prevalent among patients who underwent cancer surgery and associated with lower postoperatively daily physical activity. These data highlight the importance of addressing modifiable decisional needs of patients through enhanced shared decision-making.

Surgeons' Coaching Techniques in the Surgical Coaching for Operative Performance Enhancement (SCOPE) Program.

OBJECTIVE: To evaluate coaching techniques used by practicing surgeons who underwent dedicated coach training in a peer surgical coaching program. BACKGROUND: Surgical coaching is a developing strategy for improving surgeons' intraoperative performance. How to cultivate effective coaching skills among practicing surgeons is uncertain. METHODS: Through the Surgical Coaching for Operative Performance Enhancement (SCOPE) program, 46 surgeons within 4 US academic medical centers were assigned 1:1 into coach/coachee pairs. All attended a 3-hour Surgical Coaching Workshop-developed using evidence from the fields of surgery and education-then received weekly reminders. We analyzed workshop evaluations and audio transcripts of postoperative debriefs between coach/coachee pairs, co-coding themes based on established principles of effective coaching: (i) self-identified goals, (ii) collaborative analysis, (iii) constructive feedback, and (iv) action planning. Coaching principles were cross-referenced with intraoperative performance topics: technical, nontechnical, and teaching skills. RESULTS: For the 8 postoperative debriefs analyzed, mean duration was 24.4 min (range 7-47 minutes). Overall, 326 coaching examples were identified, demonstrating application of all 4 core principles of coaching. Constructive feedback (17.6 examples per debrief) and collaborative analysis (16.3) were utilized more frequently than goal-setting (3.9) and action planning (3.0). Debriefs focused more often on nontechnical skills (60%) than technical skills (32%) or teaching-specific skills (8%). Among surgeons who completed the workshop evaluation (82% completion rate), 90% rated the Surgical Coaching Workshop "good" or "excellent." CONCLUSIONS: Short-course coach trainings can help practicing surgeons use effective coaching techniques to guide their peers' performance improvement in a way that aligns with surgical culture.

Drivers of Cost Associated With Minimally Invasive Esophagectomy.

BACKGROUND: In this era of value-based healthcare, costs must be measured alongside patient outcomes to prioritize quality improvement and inform performance-based reimbursement strategies. We sought to identify drivers of costs for patients undergoing minimally invasive esophagectomy for esophageal cancer. METHODS: Patients who underwent minimally invasive esophagectomy for esophageal cancer from December 2008 to March 2020 were included. Our institutional Society of Thoracic Surgeons database was merged with financial data to determine inpatient direct accounting costs in 2020 US dollars for total, operative (surgery and anesthesia), and postoperative (intensive care, floor, radiology, laboratory, etc) services. A supervised machine learning quantitative method, the lasso estimator with 10-fold cross-validation, was applied to identify predictors of costs. RESULTS: In the study cohort (n = 240) most had ≥cT2 pathology (82%), adenocarcinoma histology (90%), and received neoadjuvant therapy (78%). Mean length of stay was 8.00 days (SD, 4.13) with 45% inpatient morbidity rate and no deaths. The largest proportions of cost were from the operating room (30%), inpatient floor (30%), and postanesthesia care/intensive care units (20%). Preoperative predictors of operative costs were age (-5.18% per decade [95% confidence interval {CI}, -9.95 to -0.27], P = .039), body mass index ≥ 30 (+12.9% [95% CI, 0.00-27.5], P = .050), forced expiratory volume in 1 second (-3.24% per 10% forced expiratory volume in 1 second [95% CI, -5.80 to -0.61], P = .017), and year of surgery (+2.55% [95% CI, 0.97-4.15], P = .002). Predictors of postoperative costs were postoperative renal failure (+91.6% [95% CI, 9.93-233.8], P = .022), respiratory failure (+414.6% [95% CI, 158.7-923.6], P < .001), pneumonia (+136.1% [95% CI, 71.1-225.8], P < .001), and reoperation (+60.5% [95% CI, 21.5-111.9], P = .001). CONCLUSIONS: Costs associated with minimally invasive esophagectomy are driven by preoperative risk factors and postoperative outcomes. These data enable surgeons and policymakers to reduce cost variation, improve quality through standardization, and ultimately provide greater value to patients.

Feasibility and performance of smartphone-based daily micro-surveys among patients recovering from cancer surgery.

AIMS: Daily micro-surveys, or the high-frequency administration of patient-reported outcome measures (PROMs), may provide real-time, unbiased assessments of health-related quality of life (HRQoL). We evaluated the feasibility and accuracy of daily micro-surveys using a smartphone platform among patients recovering from cancer surgery. METHODS: In a prospective study (2017-2019), patients undergoing cancer surgery downloaded a smartphone application that administered daily micro-surveys comprising five randomly selected items from the Short Form-36 (SF-36). Micro-surveys were administered without replacement until the entire SF-36 was administered weekly. The full-length SF-36 was also administered preoperatively and 4, 12, and 24 weeks postoperatively. We assessed response and completion rates between the micro-surveys and full-length SF-36, as well as agreement of responses using Bland-Altman (B&A) analyses. RESULTS: Ninety-five patients downloaded the application and were followed for a mean of 131 days [SD ± 85]. Response rates for the full-length SF-36 and micro-surveys was 76% [95%CI 69, 83], and 34% [95%CI 26, 39]. Despite lower response rates, more SF-36 surveys were collected using the daily micro-surveys compared to the intermittent full-length SF-36 (9.9 [95%CI 8.4, 12.6] vs. 3.0 [95%CI 2.8, 3.3], respectively). B&A analyses demonstrated lack of agreement between micro-surveys and SF-36. However, agreement improved with higher micro-survey completion rate. Eighty-five percent of participants reported that daily micro-surveys were not burdensome. CONCLUSION: This study suggests that collection of daily micro-surveys among patients recovering from cancer surgery is feasible using smartphones in the early postoperative period. Future implementation of daily micro-surveys may more granularly describe momentary HRQoL changes through a greater volume of self-reported survey data.

The Risk of Postoperative Complications After Major Elective Surgery in Active or Resolved COVID-19 in the United States.

OBJECTIVE: To assess the association between the timing of surgery relative to the development of Covid-19 and the risks of postoperative complications. SUMMARY BACKGROUND DATA: It is unknown whether patients who recovered from Covid-19 and then underwent a major elective operation have an increased risk of developing postoperative complications. METHODS: The risk of postoperative complications for patients with Covid-19 undergoing 18 major types of elective operations in the Covid-19 Research Database was evaluated using multivariable logistic regression. Patients were grouped by time of surgery relative to SARS-CoV-2 infection; that is, surgery performed: (1) before January 1, 2020 ("pre-Covid-19"), (2) 0 to 4 weeks after SARS-CoV-2 infection ("peri-Covid-19"), (3) 4 to 8 weeks after infection ("early post-Covid-19"), and (4) ≥8 weeks after infection ("late post-Covid-19"). RESULTS: Of the 5479 patients who met study criteria, patients with peri-Covid-19 had an elevated risk of developing postoperative pneumonia [adjusted odds ratio (aOR), 6.46; 95% confidence interval (CI): 4.06-10.27], respiratory failure (aOR, 3.36; 95% CI: 2.22-5.10), pulmonary embolism (aOR, 2.73; 95% CI: 1.35-5.53), and sepsis (aOR, 3.67; 95% CI: 2.18-6.16) when compared to pre-Covid-19 patients. Early post-Covid-19 patients had an increased risk of developing postoperative pneumonia when compared to pre-Covid-19 patients (aOR, 2.44; 95% CI: 1.20-4.96). Late post-Covid-19 patients did not have an increased risk of postoperative complications when compared to pre-Covid-19 patients. CONCLUSIONS: Major, elective surgery 0 to 4 weeks after SARS-CoV-2 infection is associated with an increased risk of postoperative complications. Surgery performed 4 to 8 weeks after SARS-CoV-2 infection is still associated with an increased risk of postoperative pneumonia, whereas surgery 8 weeks after Covid-19 diagnosis is not associated with increased complications.

Association Between USMLE Step 1 Scores and In-Training Examination Performance: A Meta-Analysis.

PURPOSE: On February 12, 2020, the sponsors of the United States Medical Licensing Examination announced that Step 1 will transition to pass/fail scoring in 2022. Step 1 performance has historically carried substantial weight in the evaluation of residency applicants and as a predictor of subsequent subject-specific medical knowledge. Using a systematic review and meta-analysis, the authors sought to determine the association between Step 1 scores and in-training examination (ITE) performance, which is often used to assess knowledge acquisition during residency. METHOD: The authors systematically searched Medline, EMBASE, and Web of Science for observational studies published from 1992 through May 10, 2020. Observational studies reporting associations between Step 1 and ITE scores, regardless of medical or surgical specialty, were eligible for inclusion. Pairs of researchers screened all studies, evaluated quality assessment using a modified Newcastle-Ottawa Scale, and extracted data in a standardized fashion. The primary endpoint was the correlation of Step 1 and ITE scores. RESULTS: Of 1,432 observational studies identified, 49 were systematically reviewed and 37 were included in the meta-analysis. Overall study quality was low to moderate. The pooled estimate of the correlation coefficient was 0.42 (95% confidence interval [CI]: 0.36, 0.48; P < .001), suggesting a weak-to-moderate positive correlation between Step 1 and ITE scores. The random-effects meta-regression found the association between Step 1 and ITE scores was weaker for surgical (versus medical) specialties (beta -0.25 [95% CI: -0.41, -0.09; P = .003]) and fellowship (versus residency) training programs (beta -0.25 [95% CI: -0.47, -0.03; P = .030]). CONCLUSIONS: The authors identified a weak-to-moderate positive correlation between Step 1 and ITE scores based on a meta-analysis of low-to-moderate quality observational data. With Step 1 scoring transitioning to pass/fail, the undergraduate and graduate medical education communities should continue to develop better tools for evaluating medical students.

Expected Versus Experienced Health-Related Quality of Life Among Patients Recovering From Cancer Surgery: A Prospective Cohort Study.

Patient expectations of the impact of surgery on postoperative health-related quality of life (HRQL) may reflect the effectiveness of patient-provider communication. We sought to compare expected versus experienced HRQL among patients undergoing cancer surgery. METHODS: Adults undergoing cancer surgery were eligible for inclusion (2017-2019). Preoperatively, patients completed a smartphone-based survey assessing expectations for HRQL 1 week and 1, 3, and 6 months postoperatively based on the 8 short-form 36 (SF36) domains (physical functioning, physical role limitations, pain, general health, vitality, social functioning, emotional role limitations, and mental health). Experienced HRQL was then assessed through smartphone-based SF36 surveys 1, 3, and 6 months postoperatively. Correlations between 1- and 6-month trends in expected versus experienced HRQL were determined. RESULTS: Among 101 consenting patients, 74 completed preoperative expectations and SF36 surveys (73%). The mean age was 54 years (SD 14), 49 (66%) were female, and the most common operations were for breast (34%) and abdominal (31%) tumors. Patients expected HRQL to worsen 1 week after surgery and improve toward minimal disability over 6 months. There was poor correlation (≤±0.4) between 1- and 6-month trends in expected versus experienced HRQL in all SF36 domains except for moderate correlation in physical functioning (0.50, 95% confidence interval [0.22-0.78], P < 0.001) and physical role limitations (0.41, 95% confidence interval [0.05-0.77], P = 0.024). Patients expected better HRQL than they experienced. CONCLUSIONS: Preoperative expectations of postoperative HRQL correlated poorly with lived experiences except in physical health domains. Surgeons should evaluate factors which inform expectations around physical and psychosocial health and use these data to enhance shared decision-making.

Redeployment of Health Care Workers in the COVID-19 Pandemic: A Qualitative Study of Health System Leaders' Strategies.

OBJECTIVES: This study aimed to determine the strategies used and critical considerations among an international sample of hospital leaders when mobilizing human resources in response to the clinical demands associated with the COVID-19 pandemic surge. METHODS: This was a cross-sectional, qualitative research study designed to investigate strategies used by health system leaders from around the world when mobilizing human resources in response to the global COVD-19 pandemic. Prospective interviewees were identified through nonprobability and purposive sampling methods from May to July 2020. The primary outcomes were the critical considerations, as perceived by health system leaders, when redeploying health care workers during the COVID-19 pandemic determined through thematic analysis of transcribed notes. Redeployment was defined as reassigning personnel to a different location or retraining personnel for a different task. RESULTS: Nine hospital leaders from 9 hospitals in 8 health systems located in 5 countries (United States, United Kingdom, New Zealand, Singapore, and South Korea) were interviewed. Six hospitals in 5 health systems experienced a surge of critically ill patients with COVID-19, and the remaining 3 hospitals anticipated, but did not experience, a similar surge. Seven of 8 hospitals redeployed their health care workforce, and 1 had a redeployment plan in place but did not need to use it. Thematic analysis of the interview notes identified 3 themes representing effective practices and lessons learned when preparing and executing workforce redeployment: process, leadership, and communication. Critical considerations within each theme were identified. Because of the various expertise of redeployed personnel, retraining had to be customized and a decentralized flexible strategy was implemented. There were 3 concerns regarding redeployed personnel. These included the fear of becoming infected, the concern over their skills and patient safety, and concerns regarding professional loss (such as loss of education opportunities in their chosen profession). Transparency via multiple different types of communications is important to prevent the development of doubt and rumors. CONCLUSIONS: Redeployment strategies should critically consider the process of redeploying and supporting the health care workforce, decentralized leadership that encourages and supports local implementation of system-wide plans, and communication that is transparent, regular, consistent, and informed by data.
