Examining online international health professions education: a mixed methods review of barriers, facilitators, and early outcomes☠.

BACKGROUND: Access to quality healthcare education across the world is disproportionate. This study explores the potential for Cardiovascular Perfusion education to be delivered online to reach international students. METHODS: Exploratory mixed methods were used to identify the barriers, facilitators, and early outcomes of online international health professions education. RESULTS: Qualitative analysis yielded four primary and nine subthemes. Multiple interventions were implemented in the planning of a novel online international Extracorporeal Science (ECS) program based on these themes. Quantitative data from the first semester of the new ECS program was collected along with data from the traditional entry-level program and historic data from previous entry-level cohorts. No significant correlations or differences were found between students. Student satisfaction surveys were determined to be equivalent for each group. Mixed data analysis revealed exceptional student satisfaction in areas where qualitative feedback was incorporated into the program design. CONCLUSIONS: Online international education may be a viable option in the health professions. Barriers and facilitators to this mode of education were identified and utilized in designing one such program. Early outcomes from the novel ECS program reveal that student performance and satisfaction are equivalent to those of a traditional in-person training program.

The impact of heart valve and partial heart transplant models on the development of banking methods for tissues and organs: A concise review.

Cryopreserved human heart valves fill a crucial role in the treatment for congenital cardiac anomalies, since the use of alternative mechanical and xenogeneic tissue valves have historically been limited in babies. Heart valve models have been used since 1998 to better understand the impact of cryopreservation variables on the heart valve tissue components with the ultimate goals of improving cryopreserved tissue outcomes and potentially extrapolating results with tissues to organs. Cryopreservation traditionally relies on conventional freezing, employing cryoprotective agents, and slow cooling to sub-zero centigrade temperatures; but it is plagued by the formation of ice crystals and cell damage upon thawing. Researchers have identified ice-free vitrification procedures and developed a new rapid warming method termed nanowarming. Nanowarming is an emerging method that utilizes targeted application of energy at the nanoscale level to rapidly rewarm vitrified tissues, such as heart valves, uniformly for transplantation. Vitrification and nanowarming methods hold great promise for surgery, enabling the storage and transplantation of tissues for various applications, including tissue repair and replacement. These innovations have the potential to revolutionize complex tissue and organ transplantation, including partial heart transplantation. Banking these grafts addresses organ scarcity by extending preservation duration while preserving biological activity with maintenance of structural fidelity. While ice-free vitrification and nanowarming show remarkable potential, they are still in early development. Further interdisciplinary research must be dedicated to exploring the remaining challenges that include scalability, optimizing cryoprotectant solutions, and ensuring long-term viability upon rewarming in vitro and in vivo.

Advancing cardiotomy suction practices for coronary surgery via multidisciplinary collaborative learning.

Objective: Professional standards recommend stopping cardiotomy suction at the termination of cardiopulmonary bypass before protamine administration based on perceived safety concerns. This study evaluated a multidisciplinary collaborative quality-improvement intervention promoting this agreed-upon cardiotomy suction practice during coronary artery bypass grafting (CABG). Methods: A statewide intervention (eg, unblinded surgeon and perfusionist feedback, evidence-based lectures, evaluating barriers to change) involved 32 centers participating in the PERForm (ie, Perfusion Measures and Outcomes) Registry to standardize cardiotomy suction practices at cardiopulmonary bypass termination during CABG. Four non-Michigan registry participating centers were not exposed to collaborative learning. Cardiotomy suction practice was defined as the absence of or stopping cardiotomy suction before protamine administration. The practice changes attributed to the intervention, including Michigan and non-Michigan comparisons, were evaluated with the change of time effect modeled using splines. Multivariable regression was used to evaluate the intervention's associated impact (eg, mortality, reoperation, transfusion). Results: Among 10,394 patients undergoing CABG at Michigan centers, 80.7% achieved agreed-upon cardiotomy suction practices. The Michigan centers had nonsignificant changes in agreed-upon cardiotomy suction practices during the preintervention period (P = .24), with significant increased monthly change in practice thereafter, absent adjusted morbidity and mortality increases. The Michigan centers achieved a significantly greater adjusted monthly improvement in agreed-upon practices relative to non-Michigan centers within 7 months after the intervention (adjusted odds ratio for change of trends: 2.53, P < .001). Conclusions: This initiative demonstrates the effectiveness of multidisciplinary collaborative quality improvement in advancing agreed-upon cardiotomy suction practices without negatively impacting clinical outcomes.

Birinapant selectively enhances immunotoxin-mediated killing of cancer cells conditional on the IAP protein levels within target cells.

Immunotoxins (ITs) target cancer cells via antibody binding to surface antigens followed by internalization and toxin-mediated inhibition of protein synthesis. The fate of cells responding to IT treatment depends on the amount and stability of specific pro-apoptotic and pro-survival proteins. When treated with a pseudomonas exotoxin-based immunotoxin (HB21PE40), the triple-negative breast cancer (TNBC) cell line MDA-MB-468 displayed a notable resistance to toxin-mediated killing compared to the epidermoid carcinoma cell line, A431, despite succumbing to the same level of protein synthesis inhibition. In a combination screen of ~1912 clinically relevant and mechanistically annotated compounds, we identified several agents that greatly enhanced IT-mediated killing of MDA-MB-468 cells while exhibiting only a modest enhancement for A431 cells. Of interest, two Smac mimetics, birinapant and SM164, exhibited this kind of differential enhancement. To investigate the basis for this, we probed cells for the presence of inhibitor of apoptosis (IAP) proteins and monitored their stability after the addition of immunotoxin. We found that high levels of IAPs inhibited immunotoxin-mediated cell death. Further, TNFα levels were not relevant for the combination's efficacy. In tumor xenograft studies, combinations of immunotoxin and birinapant caused complete regressions in MDA-MB-468tumor-bearing mice but not in mice with A431 tumors. We propose that IAPs constitute a barrier to immunotoxin efficacy which can be overcome with combination treatments that include Smac mimetics.

del Nido versus blood cardioplegia in cardiac surgery: A multicenter analysis of over 40,000 patients.

OBJECTIVES: The use of del Nido cardioplegia in adult cardiac surgery is rising in popularity. The objective of this large multicenter study was to evaluate the use and associated outcomes of del Nido versus blood cardioplegia in adult cardiac surgery. METHODS: Patients undergoing coronary artery bypass grafting (CABG) and/or valve (mitral, aortic), and/or nondescending thoracic aortic surgery (July 2014 to March 2022) across 39 centers were extracted from the Perfusion Measures and Outcomes registry. Patients were stratified by cardioplegia type for unadjusted analysis and multivariable mixed-effects models were used for risk adjustment. RESULTS: Of 44,175 patients, 42.5% used del Nido, with use increasing 48% over time. Overall, the del Nido group had shorter median crossclamp time (74 minutes vs 87 minutes, P < .001) and lower median peak intraoperative glucose levels (161 mg/dL vs 180 mg/dL, P < .001). Use of del Nido was not associated with operative mortality (adjusted odds ratio [ORadj], 1.16; P = .075) nor major morbidity (ORadj, 1.05; P = .25). Findings for valve cases were similar, except crossclamp time differences were variable by type of valve procedure. Within the CABG subgroup there was a trend toward increased operative mortality with del Nido (ORadj, 1.24; P = .069), whereas the risk of renal failure approaches statistical significance in the aortic subgroup (ORadj, 1.54; P = .056). CONCLUSIONS: In this large, multicenter study, the use of del Nido was associated with variable crossclamp time differences, lower intraoperative glucose levels, and no significant difference in major morbidity or mortality. Efficiency benefits of del Nido may be limited in valve cases, whereas outcomes in CABG and aortic cases warrant further study.

Nontechnical Skills for Intraoperative Team Members.

Nontechnical skills, defined as the set of cognitive and social skills used by individuals and teams to reduce error and improve performance in complex systems, have become increasingly recognized as a key contributor to patient safety. Efforts to characterize, quantify, and teach nontechnical skills in the context of perioperative care continue to evolve. This review article summarizes the essential behaviors for safety, described in taxonomies for nontechnical skills assessments developed for intraoperative clinical team members (eg, surgeons, anesthesiologists, scrub practitioners, perfusionists). Furthermore, the authors describe emerging methods to advance understanding of the impact of nontechnical skills on perioperative outcomes.

A quality improvement initiative to increase adult ECMO decision-making abilities in a perfusion education program: The use of 3D ECMO simulation.

INTRODUCTION: Adult and pediatric ECMO procedures have been increasingly established as conventional life-saving modalities in critical care services across the world. Since 2017, a multidisciplinary team of program advisors for our perfusion education program have aimed to increase cardiovascular perfusion (CVP) student ECMO exposure and improve clinical decision-making. In this QI intervention, the use of 3D computer-based simulation was assessed in establishing a standardized process to improve the diagnosis and treatment of adult ECMO complications among first year CVP students. METHODS: The Califia 3D Patient Simulator was incorporated into the curriculum for first year CVP students (n = 26) along with traditional lecture for the adult ECMO complication laboratory session. Pre-class knowledge assessments using de-identified polling software were compared to post-class assessments following the first assigned learning activity. Assessments from students that received simulation before lecture (SIM, n = 15) were compared to students receiving lecture before simulation (LEC, n = 11). User experience questionnaires (UEQ) consisting of 26 questions for six scales of simulation instruction were administered to measure the comprehensive impression of the student experience. RESULTS: Overall median [IQR] pre- and -post knowledge assessment scores were 74% [11] and 84% [11], respectively (p = 0.01). There were no significant differences in pre-class assessment scores between the SIM and LEC groups (74.0% and 74.0%, respectively, p = 0.959). The LEC group achieved higher median post-assessment scores than the SIM group (84% vs 79%, p = 0.032). Among the 26 UEQ survey scales, 23 were positively evaluated (>0.8), and three were a neutral evaluation (-0.8 to 0.8). Cronbach Alpha-Coefficients of >0.78 were measured for attractiveness, perspicuity, efficacy, and stimulation. The coefficient for dependability was 0.37. 25 (96.2%) students indicated that 3D simulation was beneficial to improving ECMO clinical decision-making. CONCLUSIONS: In this QI intervention, the implementation of computer-based 3D simulation following lecture was perceived by learners to help improve the diagnosis and treatment of ECMO-related complications.

Adult Clinical Perfusion Practice Survey: 2020 results.

Background: Cardiovascular perfusion is a dynamic healthcare profession where new practices are frequently introduced. Despite the emergence of evidence-based clinical practice guidelines, little is known about their dissemination at the institutional level. Clinical practice surveys have been used to identify current trends in perfusion practice in the areas of equipment, techniques, and staffing. This survey aims to describe clinical perfusion practices across adult cardiac surgical programs located in a large, single, geographical region of the United States. Methods: Following Institutional Review Board (IRB) approval, an 81-question survey was distributed to 167 adult perfusion programs across the Zone IV region of the American Society of Extracorporeal Technology (AmSECT), a non-profit professional society representing the extracorporeal technology community. Surveys were distributed to chief perfusionists through the Research Electronic Data Capture (REDCap) web-based survey response system. Results: Responses were received from 58 of 167 centers across (34.7% response rate). Centrifugal pumps were used at 81% (n = 47) of centers and 96.6% (n = 56) use an open venous system or hard-shell venous reservoir. Del Nido was the most frequently used cardioplegia strategy with 62.1% (n = 36) of centers reporting its use. The use of electronic medical records was reported in 43% (n = 25) of centers, while 84.5% (n = 49) reported using Cardiopulmonary Bypass (CPB) protocols (>75% of all CPB activities). Extracorporeal Membrane Oxygenation (ECMO) support was reported in 93.1% (n = 54) of programs, with 59.2% of programs (n = 34) employing a perfusionist as ECMO Coordinator. The n + 1 staffing model was reported by 50% (n = 29), with 24% supporting the n + 1 staffing for after-hours and on-call procedures. Conclusion: Clinical practice surveys can be effective tools to inform clinicians about contemporary perfusion practice and identify deviations from professional standards and guidelines. Subsequent surveys may describe trends over time, assess standardization of practice, measure adherence to evidence-based guidelines, and foster improved patient care and outcomes.

Cell-specific cargo delivery using synthetic bacterial spores.

Delivery of cancer therapeutics to non-specific sites decreases treatment efficacy while increasing toxicity. In ovarian cancer, overexpression of the cell surface marker HER2, which several therapeutics target, relates to poor prognosis. We recently reported the assembly of biocompatible bacterial spore-like particles, termed "SSHELs." Here, we modify SSHELs with an affibody directed against HER2 and load them with the chemotherapeutic agent doxorubicin. Drug-loaded SSHELs reduce tumor growth and increase survival with lower toxicity in a mouse tumor xenograft model compared with free drug and with liposomal doxorubicin by preferentially accumulating in the tumor mass. Target cells actively internalize and then traffic bound SSHELs to acidic compartments, whereupon the cargo is released to the cytosol in a pH-dependent manner. We propose that SSHELs represent a versatile strategy for targeted drug delivery, especially in cancer settings.

A tool to assess nontechnical skills of perfusionists in the cardiac operating room.

OBJECTIVES: This study aimed to develop the Perfusionists' Intraoperative Non-Technical Skills tool, specifically to the perfusionists' context, and test its inter-rater reliability. METHODS: An expert panel was convened to review existing surgical nontechnical skills taxonomies and develop the Perfusionists' Intraoperative Non-Technical Skills tool. During a workshop held at a national meeting, perfusionists completed the Perfusionists' Intraoperative Non-Technical Skills ratings after watching 4 videos displaying simulated cardiac operations. Two videos showed "good performance," and 2 videos showed "poor performance." Inter-rater reliability analysis was performed and intraclass correlation coefficient was reported. RESULTS: The final version of the Perfusionists' Intraoperative Non-Technical Skills taxonomy contains 4 behavioral categories (decision making, situation awareness, task management and leadership, teamwork and communication) with 4 behavioral elements each. Categories and elements are rated using an 8-point Likert scale ranging from 0.5 to 4.0. A total of 60 perfusionist raters were included and the comparison between rating distribution on "poor performance" and "good performance" videos yielded a statistically significant difference between groups, with a P value less than .001. A similar difference was found in all behavioral categories and elements. Reliability analysis showed moderate inter-rater reliability across overall ratings (intraclass correlation coefficient, 0.735; 95% confidence interval, 0.674-0.796; P < .001). Similar inter-rater reliability was found when raters were stratified by experience level. CONCLUSIONS: The Perfusionists' Intraoperative Non-Technical Skills tool presented moderate inter-rater reliability among perfusionists with varied levels of experience. This tool can be used to train and assess perfusionists in relevant nontechnical skills, with the potential to enhance safety and improve surgical outcomes.

An investigation of the use of app technology to support clinical management of patients with chronic myeloid leukaemia (CML).

INTRODUCTION: The availability of healthcare apps to support patient self-management of various medical conditions, including cancer, has increased considerably in the past decade. However, there are limited published data on the role of apps in the management of chronic myeloid leukaemia (CML). The primary aim of this study was to investigate the current and future role of apps as a means of supporting patients with CML. METHODS: A 31-item questionnaire was developed and distributed to patients via three on-line CML support groups. RESULTS: Responses were received from 286 patients. There was an approximate 2:1 female: male split and the majority (54%, n = 155) resided in the United Kingdom. 91% (n = 260) of respondents were currently receiving drug treatment for their CML. 23.4% (n = 67) of respondents were aware that apps were available to support their CML management and 11.5% (n = 33) had experience of using such an app. 94.1% (n = 238) of those who had not used a patient support app in the past stated that they would consider using an app in the future to help manage their disease. App awareness was significantly higher amongst male patients (30.3% vs. 19.9%). Likelihood of being a current or previous app user was higher amongst younger patients (16.3% for <55 years old vs. 5.6% for ≥55 years old) whilst younger patients and those with a more recent diagnosis of CML were both more likely to be interested in using an app in the future. When asked about potential app functionality, a drug interaction checker was the feature of greatest interest to respondents. CONCLUSIONS: We have identified both a lack of awareness of and a low uptake of patient support apps amongst CML patients. Importantly, we have demonstrated a clear interest in CML-specific apps amongst this population. Based on the functionality that study participants were most interested in, we will work with health care professionals, app developers and patients to develop a new app to deliver holistic support to CML patients.

Antibody drug conjugates, targeting cancer-expressed EGFR, exhibit potent and specific antitumor activity.

The monoclonal antibody '40H3' binds to EGFRvIII and to full-length EGFR when it is overexpressed on cancer cells. To generate candidate cytotoxic antibody-drug conjugates (ADCs), 40H3 was modified by the addition of small molecular weight payloads that included two tubulin-modifying agents, two topoisomerase inhibitors and a pyrrolobenzodiazepine (PBD) dimer. Conjugates retained antigen binding activity comparable to the unmodified 40H3 antibody. The cytotoxicity of five distinct ADCs was evaluated on a variety of EGFR-expressing cells including three triple negative breast cancer (TNBC) lines. Generally, the 40H3 conjugate with the PBD dimer (40H3-Tesirine) was the most active killing agent. The killing of EGFR-positive cells by 40H3-Tesirine correlated with the number of surface binding sites for 40H3. However, bystander killing was also evident in experiments with antigen-negative cells. In vivo tumor xenograft experiments were conducted on two TNBC tumor lines. Three treatments with the 40H3-Tesirine ADC at 1 mg/kg were sufficient to achieve complete remissions without evidence of mouse toxicity. Data support the development of ADCs derived from the 40H3 antibody for the treatment of cancers that express EGFRvIII or high levels of EGFR.

Managing the TME to improve the efficacy of cancer therapy.

The tumor microenvironment (TME) influences tumor growth, metastatic spread and response to treatment. Often immunosuppression, mediated by the TME, impairs a beneficial response. The complexity of the tumor composition challenges our abilities to design new and more effective therapies. Going forward we will need to 'manage' the content and or functionality of the TME to improve treatment outcomes. Currently, several different kinds of treatments are available to patients with cancer: there are the traditional approaches of chemotherapy, radiation and surgery; there are targeted agents that inhibit kinases associated with oncogenic pathways; there are monoclonal antibodies that target surface antigens often delivering toxic payloads or cells and finally there are antibodies and biologics that seek to overcome the immunosuppression caused by elements within the TME. How each of these therapies interact with the TME is currently under intense and widespread investigation. In this review we describe how the TME and its immunosuppressive components can influence both tumor progression and response to treatment focusing on three particular tumor types, classic Hodgkin Lymphoma (cHL), Pancreatic Ductal Adenocarcinoma (PDAC) and Glioblastoma Multiforme (GBM). And, finally, we offer five approaches to manipulate or manage the TME to improve outcomes for cancer patients.

Impact of hidradenitis suppurativa-specific wound dressing system on patient quality of life and dressing-related pain: pilot study.

OBJECTIVE: It is theorised that adhesive-free wound care developed specifically for patients with hidradenitis suppurativa (HS) can improve their quality of life (QoL). Our study aimed to investigate the impact of a novel wound care device on Dermatology Life Quality Index (DLQI) scores, and other factors related to experienced pain, time spent changing dressings, comfort, ease of use and body image. METHOD: A 21-day, single-arm, unblinded, pilot trial was conducted to assess ease of use and the impact of effective wound care on various aspects of wound management in patients with HS. Participants were provided two trial garments and trial dressings as required, to use over a 21-day period in the home setting. A seven-item questionnaire and the DLQI questionnaire was completed on days 0, 7, 14 and 21. RESULTS: All 15 participants were female, aged >18 years old and with a diagnosis of HS. Mean DLQI score at baseline (day 0) was 19.3, which was reduced to 4.53 on day 21, a significant improvement in 100% of participants (p<0.001). High levels of dressing-related pain, assessed using an 11-point Visual Analogue Scale, reduced from 5.53 at baseline to 0.8 on day 21. Other significant improvements in terms of patient comfort, time spent on changing dressings, body confidence and the dressing's ability to retain exudate were also noted. CONCLUSION: The results illustrated the improvement made to study participants' day-to-day activities and QoL when effective HS-specific wound care products were provided. Wound care is an essential component in the treatment journey of patients.

The Role of Race on Acute Kidney Injury After Cardiac Surgery.

BACKGROUND: Acute kidney injury (AKI) frequently complicates cardiac surgery and is more common among Black patients. We evaluated determinants of race-based differences in AKI rates. METHODS: Serum creatinine-based criteria were used to identify adult cardiac surgical patients having postoperative AKI in the Perfusion Measures and Outcomes (PERForm) Registry (July 1, 2014, to June 30, 2019). Patient characteristics, operative details, and outcomes were compared by race (Black vs White) after excluding patients with preoperative dialysis, missing preoperative or postoperative creatinine, or other races. A mixed effects model (adjusting for demographics, comorbidities, surgical factors) used hospital as a random effect to predict postoperative stage 2 or 3 AKI. Propensity score analyses were conducted to evaluate robustness of the primary analyses. RESULTS: The study cohort included 34 520 patients (8% Black). More Black patients than White patients were female (43% vs 27%, P < .001), and had hypertension (93% vs 87%, P < .001) and diabetes mellitus (51% vs 41%, P < .001). Acute kidney injury of stage 2 or greater occurred in 1697 patients (5%), more often among Black than White patients (8% vs 5%, P < .001). Intraoperatively, Black patients had lower nadir hematocrits (23 vs 26, P < .001), and were more likely to be given transfusions (22% vs 14%, P < .001). After adjustment, Black race (compared with White) independently predicted odds for postoperative AKI (adjusted odds ratio 1.50; 95% confidence interval, 1.26 to 1.78). The multivariable findings were similar in propensity score analyses. CONCLUSIONS: Despite accounting for differences in risk factors and intraoperative practices, Black patients had a 50% increased odds for having moderate-severe postoperative AKI compared with White patients. Additional evaluations are warranted to identify potential targets to address racial disparities in AKI outcomes.

Determinants of hospital variability in perioperative red blood cell transfusions during coronary artery bypass graft surgery.

OBJECTIVE: To identify to what extent distinguishing patient and procedural characteristics can explain center-level transfusion variation during coronary artery bypass grafting surgery. METHODS: Observational cohort study using the Perfusion Measures and Outcomes Registry from 43 adult cardiac surgical programs from July 1, 2011, to July 1, 2017. Iterative multilevel logistic regression models were constructed using patient demographic characteristics, preoperative risk factors, and intraoperative conservation strategies to progressively explain center-level transfusion variation. RESULTS: Of the 22,272 adult patients undergoing isolated coronary artery bypass surgery using cardiopulmonary bypass, 7241 (32.5%) received at least 1 U allogeneic red blood cells (range, 10.9%-59.9%). When compared with patients who were not transfused, patients who received at least 1 U red blood cells were older (68 vs 64 years; P < .001), were women (41.5% vs 15.9%; P < .001), and had a lower body surface area (1.93 m2 vs 2.07 m2; P < .001), respectively. Among the models explaining center-level transfusion variability, the intraclass correlation coefficients were 0.07 for model 1 (random intercepts), 0.12 for model 2 (patient factors), 0.14 for model 3 (intraoperative factors), and 0.11 for model 4 (combined). The coefficient of variation for center-level transfusion rates were 0.31, 0.29, 0.40, and 0.30 for models 1 through 4, respectively. The majority of center-level variation could not be explained through models containing both patient and intraoperative factors. CONCLUSIONS: The results suggest that variation in center-level red blood cells transfusion cannot be explained by patient and procedural factors alone. Investigating organizational culture and programmatic infrastructure may be necessary to better understand variation in transfusion practices.

The Effect of Aerobic Exercise on Concussion Recovery: A Pilot Clinical Trial.

OBJECTIVE: The purpose of this study was to pilot safety and tolerability of a 1-week aerobic exercise program during the post-acute phase of concussion (14-25 days post-injury) by examining adherence, symptom response, and key functional outcomes (e.g., cognition, mood, sleep, postural stability, and neurocognitive performance) in young adults. METHOD: A randomized, non-blinded pilot clinical trial was performed to compare the effects of aerobic versus non-aerobic exercise (placebo) in concussion patients. The study enrolled three groups: 1) patients with concussion/mild traumatic brain injury (mTBI) randomized to an aerobic exercise intervention performed daily for 1-week, 2) patients with concussion/mTBI randomized to a non-aerobic (stretching and calisthenics) exercise program performed daily for 1-week, and 3) non-injured, no intervention reference group. RESULTS: Mixed-model analysis of variance results indicated a significant decrease in symptom severity scores from pre- to post-intervention (mean difference = -7.44, 95% CI [-12.37, -2.20]) for both concussion groups. However, the pre- to post-change was not different between groups. Secondary outcomes all showed improvements by post-intervention, but no differences in trajectory between the groups. By three months post-injury, all outcomes in the concussion groups were within ranges of the non-injured reference group. CONCLUSIONS: Results from this study indicate that the feasibility and tolerability of administering aerobic exercise via stationary cycling in the post-acute time frame following post-concussion (14-25 days) period are tentatively favorable. Aerobic exercise does not appear to negatively impact recovery trajectories of neurobehavioral outcomes; however, tolerability may be poorer for patients with high symptom burden.

Models of care for chronic myeloid leukemia patients during the COVID-19 pandemic in the United Kingdom: Changes in patient attitudes to remote consultations and future implications.

The ongoing COVID-19 pandemic has presented numerous challenges to the provision of patient care within hematology. We undertook a questionnaire-based study investigating the experiences and opinions of patients with chronic myeloid leukemia (CML) in the UK in relation to the different models of follow-up care received during the pandemic. One hundred fifty-four patients completed the online questionnaire. Only 19% of patients had experienced remote clinics prior to the pandemic compared with 91% afterward. After having experience of remote clinics, the proportion of patients who were positive about the remote clinic concept increased from 34% to 52% (P < .05). However, when asked to compare their experiences with face to face versus remote clinics, 48% preferred face-to-face clinics compared with 17% preferring remote clinics (35% expressed no preference). During the pandemic, frequency of blood tests was unchanged for 71% of patients, although they were performed in a number of different locations. The majority of patients (57%) had medication delivered to their home, with a small number (8%) having difficulty obtaining their medication. In terms of future models of care, 72% of patients were in favor of building remote appointments into the clinic model with 61% expressing a preference for a mixture of remote and face-to-face appointments. There was also interest in greater utilization of primary care for blood testing. Our findings should help optimize future models of care for CML patients.
