The scenes of suffering in India are hard to comprehend. As of May 4, more than 20·2 million cases of COVID-19 had been reported, with a rolling average of 378ˆ000 cases a day, together with more than 222ˆ000 deaths, which experts believe are likely to be substantial underestimates. Hospitals are overwhelmed, and health workers are exhausted and becoming infected. Social media is full of desperate people (doctors and the public) seeking medical oxygen, hospital beds, and other necessities. Yet before the second wave of cases of COVID-19 began to mount in early March, Indian Minister of Health Harsh Vardhan declared that India was in the œendgame of the epidemic.

Respiratory syncytial virus (RSV) is one of the last remaining major causes of serious paediatric respiratory infection for which no vaccine or other wide-scale intervention is available. Although an effective prophylactic antibody (palivizumab) has been available for more than two decades,1 its effect on the overall disease burden has been modest. The relatively high cost of palivizumab and its narrow indication to only a small proportion of infants who are at high risk of infection1 has meant that the majority of infants at high risk from RSV do not receive palivizumab prophylaxis.

In LMICs with clear RSV seasonality, seasonal approaches to monoclonal antibody and maternal vaccine administration might optimise disease prevention by dose given compared with year-round administration. More data are needed to clarify if seasonal administration of RSV monoclonal antibodies or maternal immunisation is programmatically suitable and cost effective in LMICs.

Abstract
Objective
Rotavirus A (RVA) is a significant cause of severe diarrheal illness and one of the common causes of death in children under the age of five. This study was aimed at detecting the prevalence of RVA in Pakistan after rotavirus vaccines were introduced. Fecal samples were obtained from 813 children from different hospitals in Rawalpindi and Islamabad, Pakistan, from January 2018 to December 2018. To obtain additional information from the parents / guardians of the children, a standard questionnaire was used.
Results
Using an enzyme-linked immunosorbent assay kit (ELISA), rotavirus antigen was detected and ELISA positive samples were subjected to reverse transcription PCR (RT-PCR). The findings showed 22% prevalence of RVA in children with acute gastroenteritis (AGE) via ELISA and 21% prevalence via RT-PCR in children with AGE. There was no statistically significant difference between gender, age and RVA infections. The winter, spring and fall/autumn seasons were statistically significant for RVA prevalence.
Conclusion
The present study will provide post vaccine prevalence data for the health policy makers. The implementation of rotavirus vaccines, along with adequate nutrition for babies, clean water supply and maternal hygienic activities during infant feeding, is recommended. Furthermore, continuous surveillance is mandatory in the whole country to calculate the disease burden caused by RVA.

On March 2019 the World Health Organization declared Coronavirus disease (COVID-19) pandemic. Several recent reports disclose that the outcome of the infection is related to age, sex and can be influenced by underlying clinical conditions. Parkinson™s disease (PD) and other parkinsonisms are the most common chronic disease which can cause, directly or indirectly, the patient to be more exposed to other diseases, mostly respiratory system™s ones. Our primary outcome is to evaluate if PD patients are more susceptible than non-PD to take COVID-19 infection. Second, to detect if the infection course is worse in PD-COVID+ patients versus non-PD. This is a retrospective observational study on a cohort of 18 patients (13 PD- 5 non-PD), hospitalized in a Rehabilitative Unit during the occurrence of SARS-CoV2 epidemic outbreak. All patients performed laboratory tests, lung Computed Tomography (CT) and have been tested for COVID-19 thorough pharyngeal swab. PD and non-PD groups were comparable for age, gender and Hoehn and Yahr stage. Seventy-seven (77)% of PD and 60% of non-PD resulted positive for COVID-19. PD-COVID+ and PD-COVID- did not differ for age, disease duration and L-dopa daily dose. PD COVID-19+ subjects were mainly asymptomatic (50%) while non-PD ones were all symptomatic, mostly with respiratory difficulties. PD doesn™t seem to be a risk factor to take SARS-COV2 infection, even if our study is related to a limited sample size. Our results, together with those of other recent studies, highlight the need to evaluate the actual susceptibility of patients with Parkinson™s disease to develop COVID-19 disease, and how the infection may influence the risk of clinical worsening and increase of mortality.

Study hypothesis Cardiopulmonary resuscitation (CPR) training can increase the likelihood of patient survival and better neurological outcomes. However, conventional learning (CL) has cost, time, and space constraints. This study aimed to evaluate whether laypersons who completed instructor-led distance learning (DL) acquired a level of CPR skill comparable to that achieved via CL training.
Methods This randomized controlled study recruited students from 28 Korean high schools who were randomized to complete instructor-led DL or CL training. The CL training involved classroom-based face-to-face training, whereas the instructor-led DL training was provided online using a videoconferencing system.
Results The study enrolled 62 students who were randomized to the CL group (31 participants) or the DL group (31 participants). Relative to the CL group, the DL group achieved remarkably similar results in terms of most CPR variables. In addition, the DL group had a significant improvement in the mean compression depth (before: 46 mm [interquartile range: 37-52 mm] vs. after: 49 mm [interquartile range: 46-54 mm], p<0.001).
Conclusions Instructor-led DL can be a suitable alternative to CL for providing CPR training to laypersons. In settings like the current COVID-19 pandemic, where face-to-face CL is not practical, DL may be a useful tool for delivering CPR training.

Background Coronavirus disease (COVID-19), caused by Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV2), is the defining global health crisis of this time. It is responsible for significant morbidity and has had severe socioeconomic consequences. This study aims to assess the knowledge, preparedness and attitudes of medical students, physicians and faculty members in the United Arab Emirates (UAE) on COVID-19 and their perspective on the roles of educational and healthcare institution towards improving pandemic preparedness and enabling optimal care.
Methodology An exploratory, descriptive cross-sectional study was conducted with 444 participants, using a non-probability convenience sampling method. English-speaking participants from the medical field aged 18 and above were included in the study. The validated questionnaire was administered online and distributed across social media platforms from May-July 2020. T-test, ANOVA, Kruskal-Wallis test and Mann-Whitney-U test were used when appropriate. Responses were analysed and statistical tests applied using IBM SPSS, version 25.
Results The knowledge scores were calculated amongst different ages and professional status, and the mean was 59.08% (SD = 12.848%). Almost half of the participants obtained poor knowledge scores (less than 60%). Most of the participants followed the latest updates on COVID-19 (86.7%). The majority opted to obtain information from the national health authorities (63.4%). The mean preparedness score among the participants was 68.65% (SD = 17.456%). Being in contact with patients significantly increased the preparedness score (p < 0.001). Only 27.9% of the participants believed their college education provided adequate knowledge to deal with epidemics or pandemics. Several barriers affect willingness to work in a pandemic, with 80.6% of participants worried about posing a risk to family members.
Conclusion This study highlights the importance of establishing tailored COVID-19 related education programs to improve knowledge levels, especially in medical students. Efforts are still needed to promote effective control measures and address the barriers affecting willingness to work in a pandemic.

To optimize HIV testing resources, programs are moving away from universal testing strategies toward a risk-based screening approach to testing children/adolescents, but there is little consensus around what defines an optimal risk screening tool. This study aimed to validate a 12-item risk screening tool among children and adolescents and provide suggested fewer-item tool options for screening both facility out-patient and community populations by age strata (

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to a global pandemic, including Indonesia. However, there are only limited data regarding the precise prevalence of the COVID-19 pandemic in Indonesia. Here, to estimate the magnitude of SARS-CoV-2 infection in East Java, Indonesia, we investigated the prevalence of immunoglobulin G (IgG) antibodies. We enrolled 1,819 individuals from June to December 2020 and observed that the subjects™ overall prevalence of IgG antibody to SARS-CoV-2 was 11.4% (207/1,819). The prevalence of anti-SARS-CoV-2 antibodies differed significantly between the job/occupation groups (P = 0.0001). A greater prevalence of IgG was detected in laboratory technicians (who take samples from suspected cases and deal with polymerase chain reaction [PCR] procedures, 22.2%) compared to medical personnel who see and take direct care of patients with COVID-19 (e.g., physicians and nurses, 6.0%), other staff in medical facilities (2.9%), general population (12.1%) and non-COVID-19 patients (14.6%). The highest prevalence among age groups was in the 40-49-year-olds (14.8%), and the lowest prevalence was in the 20-29-year-olds (7.4%). However, the younger population still showed a higher prevalence than generally reported, suggesting greater exposure to the virus but less susceptibility to the disease. A geographical difference was also observed: a higher prevalence in Surabaya (13.1%) than in Jombang (9.9%). In conclusion, the COVID-19 outbreak among asymptomatic populations was characterized by a high prevalence of infection in East Java, Indonesia.

The demands of high-performance sport are exacerbated during the lead up to the Major Games (i.e., Paralympics). The purpose of this study was to better understand the challenges experienced and strategies utilized by Australian athletes (n = 7) and coaches (n = 5) preparing for the Tokyo Paralympic Games using semi-structured interviews. The thematic analysis highlighted challenges specific to participants™ sport (e.g., budgetary constraints, decentralized experiences, athletes with various impairments), personal life (e.g., moving cities to access coaching, postponing vocational/educational developments, isolation from social circles), and associated uncertainties (e.g., COVID-19, qualifications, accreditations). Participants managed these challenges by utilizing strategies to ˜anticipate and prepare™ (e.g., detailed planning, effective communication, contingency plans) and ˜manage expectations™ (e.g., understanding specific roles and boundaries, focusing on the process [i.e., effort over results]). Trust and communication between athletes and coaches was key in coaches™ better understanding of how athletes™ impairments interact with their training and competition environments and tailor support to each athlete™s unique needs. Last, participants reflected on the ˜pressure™ of the Games due to their performance having an impact on their career trajectory ˜post-Tokyo™ with some athletes contemplating retirement and others realizing the consequences of their performance on sport-related vocation and sponsorship. Coaches also accepted the success of their programs and job security will depend on outcomes at the Games. The findings from this study shed light on factors to consider to reduce challenges for teams preparing for major competitions but also highlight key practical implications to support athletes and coaches leading up, during, and post-major Games.

Introduction The recovery of other pathogens in patients with SARS-CoV-2 infection has been reported, either at the time of a SARS-CoV-2 infection diagnosis (co-infection) or subsequently (superinfection). However, data on the prevalence, microbiology, and outcomes of co-infection and superinfection are limited. The purpose of this study was to examine the occurrence of co-infections and superinfections and their outcomes among patients with SARS-CoV-2 infection.
Patients and methods We searched literature databases for studies published from October 1, 2019, through February 8, 2021. We included studies that reported clinical features and outcomes of co-infection or superinfection of SARS-CoV-2 and other pathogens in hospitalized and non-hospitalized patients. We followed PRISMA guidelines, and we registered the protocol with PROSPERO as: CRD42020189763.
Results Of 6639 articles screened, 118 were included in the random effects meta-analysis. The pooled prevalence of co-infection was 19% (95% confidence interval [CI]: 14%-25%, I2 = 98%) and that of superinfection was 24% (95% CI: 19%-30%). Pooled prevalence of pathogen type stratified by co- or superinfection were: viral co-infections, 10% (95% CI: 6%-14%); viral superinfections, 4% (95% CI: 0%-10%); bacterial co-infections, 8% (95% CI: 5%-11%); bacterial superinfections, 20% (95% CI: 13%-28%); fungal co-infections, 4% (95% CI: 2%-7%); and fungal superinfections, 8% (95% CI: 4%-13%). Patients with a co-infection or superinfection had higher odds of dying than those who only had SARS-CoV-2 infection (odds ratio = 3.31, 95% CI: 1.82-5.99). Compared to those with co-infections, patients with superinfections had a higher prevalence of mechanical ventilation (45% [95% CI: 33%-58%] vs. 10% [95% CI: 5%-16%]), but patients with co-infections had a greater average length of hospital stay than those with superinfections (mean = 29.0 days, standard deviation [SD] = 6.7 vs. mean = 16 days, SD = 6.2, respectively).
Conclusions Our study showed that as many as 19% of patients with COVID-19 have co-infections and 24% have superinfections. The presence of either co-infection or superinfection was associated with poor outcomes, including increased mortality. Our findings support the need for diagnostic testing to identify and treat co-occurring respiratory infections among patients with SARS-CoV-2 infection.

Objectives HCV infection status awareness is crucial in the HCV care continuum for both HCV-seropositive (HCV-positive status awareness) and seronegative (HCV-negative status awareness) populations. However, trends in the unawareness of HCV infection status (UoHCV) remain unknown in HIV-positive patients. This study investigated UoHCV prevalence, the associated factors of UoHCV, and its association with HCV-related knowledge in HIV-positive patients.
Methods For this cross-sectional, multicenter, questionnaire-based study, 844 HIV-infected participants were recruited from three hospitals in Taiwan from June 2018 to March 2020. Participants were grouped by HCV serostatus (HCV-seronegative [n = 734] and HCV-seropositive [n = 110]) and categorized by their HIV diagnosis date (before 2008, 2008-2013, and 2014-2020). Exploratory factor analysis was used to categorize the 15 items of HCV-related knowledge into three domains: route of HCV transmission, HCV course and complications, and HCV treatment.
Results The prevalence of UoHCV was 58.7%-62.6% and 15.1%-31.3% in the HCV-seronegative and HCV-seropositive groups, respectively, across 3 periods. More participants with UoHCV believed that HCV infection was only contracted by intravenous injection. In the HCV-seropositive group, participants with UoHCV were more likely to have HIV diagnosis before 2008 (vs. 2014-2020), be men who have sex with men (vs. people who inject drugs), and have hepatitis A virus seronegativity. In the HCV-seronegative group, participants with UoHCV were more likely to have a recent history of sexually transmitted diseases, but had a lower education level, had received less information on HCV infection from clinicians, and were less likely to have heard of HCV infection prior to the research. UoHCV was associated with lower scores for three domains of HCV-related knowledge in both groups.
Conclusions The negative association of UoHCV with HCV-related knowledge suggests that strategies targeting patients according to their HCV serostatus should be implemented to reduce UoHCV and eradicate HCV infection among HIV-positive patients.

Aims Limb and patient outcomes in people with diabetic foot complications including diabetic foot ulcer (DFU) provided virtual triage and personalized video consultations during COVID-19 pandemic are not known.
Methods Patients with foot complications attending the diabetic foot clinic prior to lockdown who sought teleconsultations during COVID-19 lockdown underwent virtual triage to include clinical history, visual inspection of feet, domiciliary wound care (community nurse assisted dressings) and offloading instructions. The subsequent ulcer, limb and mortality outcomes during the following 24 weeks of COVID-19 lockdown (April-September 2020, group 1) were assessed and compared with those who attended foot clinic during the same period in 2019 (April-September, group 2).
Results Group 1 included 561 participants with foot complications provided with teleconsultations, median age 57 (51 to 63) years and diabetes duration of 10 (5 to 16) years. Twelve patients with severe DFU were excluded and 549 patients [357 (65%) neuropathic foot, 104 (18.9%) ischemic foot and 88 (16%) chronic Charcot foot with deformities] were evaluated. There were 227 (41.3%) participants with active DFU at start of lockdown, 32 (5.8%) with new onset ulcer during lockdown (47.1%) and 290 patients without ulcers. Group 2 included 650 participants; active foot ulcer was present in 366 patients. Wound closed or reduced in area in 78.4% of participants of group 1 compared to 76.0% (p = 0.318) in group 2. Fourteen (5.4%) patients required amputations [3 major and 11 minor] in group 1 during the study period compared to 6.8% in group 2 (p = 0.191). Twenty-one (3.8%) and 28 (4.3%) patients died (p = 0.532) during 24 weeks of follow up in group 1 and 2, respectively.
Conclusions Targeted foot-care service through virtual triage and teleconsultations during COVID-19 pandemic for people with foot complications have similar ulcer and limb outcomes compared to face-to-face foot care delivery.

Introduction The SARS-CoV-2 coronavirus pandemic may cause significant morbidity and mortality in adults, yet severe cases are rare among children. The indirect impact of the pandemic on health care delivery in general and pediatric emergency department (PED) visits in particular has been widely reported.
Aims To assess the impact of the pandemic and the social restrictions imposed in its wake on PED visits and hospitalization rates in our Israeli medical center. We also sought to track these data in relation to the variation in pandemic severity and social restrictions over time. A comparison of this data with that of the adult emergency department was also performed.
Methods Data for this study were drawn from the Shaare Zedek Medical Center (SZMC), Jerusalem, Israel computerized databank. The daily number of PED and adult ER visits as well as hospitalizations resulting from these visits during the months January-July during the years 2018, 2019, 2020 were recorded. We compared the risk ratio for hospitalization in 2019 and 2020, as well as the incidence rate ratio.
Results During March and April there was a decrease in PED visits from 4,588 visits in 2019 to 2,527 visits in 2020 (ratio = .551, 95%CI [.52,.58]. Despite the drop in PED visits, the rate of hospitalizations rose with respect to 2019 (Risk Ratio = 1.31, p < .001, 95%CI [1.17,1.47]). Similar but more moderate trends were seen in the adult ED. From May-July 2020, after the lockdown was lifted, PED visits remained 30% below the same time period from 2018 and 2019, while the hospitalization rate returned to its pre-pandemic level.
Conclusions A significant drop in PED visits is seen to extend well beyond the peak of the pandemic and the lockdown period. This highlights the potential risk of children with serious emergencies becoming casualties of the pandemic by their not being brought to medical attention. Efforts should be made to raise public awareness among parents and other caretakers of children regarding this matter.

Clinical and laboratory predictors of COVID-19 severity are now well described and combined to propose mortality or severity scores. However, they all necessitate saturable equipment such as scanners, or procedures difficult to implement such as blood gas measures. To provide an easy and fast COVID-19 severity risk score upon hospital admission, and keeping in mind the above limits, we sought for a scoring system needing limited invasive data such as a simple blood test and co-morbidity assessment by anamnesis. A retrospective study of 303 patients (203 from Bordeaux University hospital and an external independent cohort of 100 patients from Paris Pitié-Salpêtrière hospital) collected clinical and biochemical parameters at admission. Using stepwise model selection by Akaike Information Criterion (AIC), we built the severity score Covichem. Among 26 tested variables, 7: obesity, cardiovascular conditions, plasma sodium, albumin, ferritin, LDH and CK were the independent predictors of severity used in Covichem (accuracy 0.87, AUROC 0.91). Accuracy was 0.92 in the external validation cohort (89% sensitivity and 95% specificity). Covichem score could be useful as a rapid, costless and easy to implement severity assessment tool during acute COVID-19 pandemic waves.

Purpose To understand what clinical presenting features of sepsis patients are historically associated with rapid treatment involving antibiotics and fluids, as appropriate.
Design This was a retrospective, observational cohort study using a machine-learning model with an embedded feature selection mechanism (gradient boosting machine).
Methods For adult patients (age ≥ 18 years) who were admitted through Emergency Department (ED) meeting clinical criteria of severe sepsis from 11/2007 to 05/2018 at an urban tertiary academic medical center, we developed gradient boosting models (GBMs) using a total of 760 original and derived variables, including demographic variables, laboratory values, vital signs, infection diagnosis present on admission, and historical comorbidities. We identified the most impactful factors having strong association with rapid treatment, and further applied the Shapley Additive exPlanation (SHAP) values to examine the marginal effects for each factor.
Results For the subgroups with or without fluid bolus treatment component, the models achieved high accuracy of area-under-receiver-operating-curve of 0.91 [95% CI, 0.86-0.95] and 0.84 [95% CI, 0.81-0.86], and sensitivity of 0.81[95% CI, 0.72-0.87] and 0.91 [95% CI, 0.81-0.97], respectively. We identified the 20 most impactful factors associated with rapid treatment for each subgroup. In the non-hypotensive subgroup, initial physiological values were the most impactful to the model, while in the fluid bolus subgroup, value minima and maxima tended to be the most impactful.
Conclusion These machine learning methods identified factors associated with rapid treatment of severe sepsis patients from a large volume of high-dimensional clinical data. The results provide insight into differences in the rapid provision of treatment among patients with sepsis.

Background Drug resistance tuberculosis (DR-TB) patients™ mortality and loss to follow-up (LTF) from treatment and care is a growing worry in Ethiopia. However, little is known about predictors of mortality and LTF among drug-resistant tuberculosis patients in Oromia region, Ethiopia. The current study aimed to identify predictors of mortality and loss to follow-up among drug resistance tuberculosis patients in Oromia Hospitals, Ethiopia.
Methods A retrospective follow up study was carried out from 01 November 2012 to 31 December 2017 among DR-TB patients after calculating sample size using single proportion population formula. Mean, median, Frequency tables and bar charts were used to describe patients™ characteristics in the cohort. The Kaplan-Meier curve was used to estimate the probability of death and LTF after the treatment was initiated. The log-rank test was used to compare time to death and time to LTF. The Cox proportional hazard model was used to determine predictors of mortality and LTF after DR-TB diagnosis. The Crude and adjusted Cox proportional hazard ratio was used to measure the strength of association whereas p-value less than 0.05 were used to declare statistically significant predictors.
Result A total of 406 DR-TB patients were followed for 7084 person-months observations. Among the patients, 71 (17.5%) died and 32 (7.9%) were lost to follow up (LTF). The incidence density of death and LTF in the cohort was 9.8 and 4.5 per 1000 person-months, respectively. The median age of the study participants was 28 years (IQR: 27.1, 29.1). The overall cumulative survival probability of patients at the end of 24 months was 77.5% and 84.5% for the mortality and LTF, respectively. The independent predictors of death was chest radiographic findings (AHR = 0.37, 95% CI: 0.17-0.79) and HIV serostatus 2.98 (95% CI: 1.72-5.19). Drug adverse effect (AHR = 6.1; 95% CI: 2.5, 14.34) and culture test result (AHR = 0.1; 95% CI: 0.1, 0.3) were independent predictors of LTF.
Conclusion This study concluded that drug-resistant tuberculosis mortality and LTF remains high in the study area. Continual support of the integration of TB/HIV service with emphasis and work to identified predictors may help in reducing drug-resistant tuberculosis mortality and LTF.

Dugan et al. utilize a multi-antigen bait sorting and single cell sequencing approach to profile B cell immunodominance upon SARS-CoV-2 infection, revealing a dynamic response that evolves toward internal virus proteins over time. Antibodies to internal proteins were non-protective in vivo, suggesting vaccination may generate superior anti-spike immunological memory.

Objective
To understand the outcome of hospitalised patients from Mumbai City, which had the highest number of COVID-19 cases in India.
Design
Observational study with follow-up.
Setting
Data extraction from medical records of patients with COVID-19 admitted to Nair Hospital & TN Medical College, Mumbai, India.
Participants
689 patients with COVID-19 were admitted in the hospital from 26 March 2020 to 11 May 2020.
Primary and secondary outcome measures
In-hospital mortality; joint effect of comorbidity and age on the risk of dying.
Results
A total of 689 patients (median age 44 years) admitted with RT-PCR-confirmed COVID-19 were included in the study. Of these, 77.36% of patients were discharged alive while 22.64% died. 11.61% required some kind of oxygen support while 2.8% of patients required intensive care unit admissions. Older age (HR 2.88, 95% CI 2.09 to 3.98), presence of comorbidities (HR 2.56, 95% CI 1.84 to 3.55), history of hypertension (HR 3.19, 95% CI 1.67 to 6.08), and presence of symptoms at the time of admission (HR 3.21, 95% CI 1.41 to 7.26) were associated with increased risk of in-hospital mortality. Treatment with a combination of azithromycin with hydroxychloroquine, antiviral or steroid compared with no treatment did not alter the disease course and in-hospital mortality. The combined effect of old age and presence of comorbid conditions was more pronounced in women than men.
Conclusions
In-hospital patients were younger, less symptomatic with lesser need of ventilators and oxygen support as compared with many western countries.
Trial registration
Not applicable (observational study, not a clinical trial).

Introduction
Sars-CoV-2 is a novel coronavirus responsible for COVID-19 officially declared pandemic in March 2020. Health systems worldwide responded with swift changes to increase workflow capacity while protecting the vulnerable, including those with cancer. This led to unprecedented and rapid restructuring of health service provision. Published data from the 2003 SARS pandemic focuses on medical and nursing staff, overlooking other departmental employees such as administration officers or food service workers. Our protocol aims to document directives and adjustments communicated to staff in two cancer care departments and correlate this with measures of distress and perceived preparedness across the spectrum of all staff involved in cancer care.
Methods and analysis
We use a semiqualitative approach comprising weekly diarising of events and simultaneous staff surveys. Principal investigators will document changes at a metropolitan quaternary cancer centre and a regional cancer centre. Communications, directives and changes will be diarised in real time in four executional domains. Simultaneously, prospective voluntary self-administered online surveys will be conducted at regular intervals by staff. The survey assesses the perceived institutional preparedness and personal well-being, with a combination of Likert scaled and open response questions. A semiquantitative self-assessment of distress adapted from National Comprehensive Cancer Network distress thermometer is incorporated. Additionally, open-text personal reflections on themes including difficult decisions will be invited. Survey participants will be drawn from various work areas of the cancer care departments: administrative staff, health professionals, for example, allied health, ancillary workers, nursing and medical.
Ethics and dissemination
The study has been reviewed and approved by the Human Research Ethics Committee (LNR/2020/QRBW/62982). Published literature on domains of distress neglects categories of healthcare worker who form an essential part of the care delivery team. Our study hopes to gather insights about psychosocial impact and adjustment which could direct responses in future emergencies.
