The impact and challenges of implementing CTCA according to the 2019 ESC guidelines on chronic coronary syndromes: a survey and projection of CTCA services in the Netherlands

Background The 2019 ESC-guidelines on chronic coronary syndromes (ESC-CCS) recommend computed tomographic coronary angiography (CTCA) or non-invasive functional imaging instead of exercise ECG as initial test to diagnose obstructive coronary artery disease. Since impact and challenges of these guidelines are unknown, we studied the current utilisation of CTCA-services, status of CTCA-protocols and modeled the expected impact of these guidelines in the Netherlands. Methods and results A survey on current practice and CTCA utilisation was disseminated to every Dutch hospital organisation providing outpatient cardiology care and modeled the required CTCA capacity for implementation of the ESC guideline, based on these national figures and expert consensus. Survey response rate was 100% (68/68 hospital organisations). In 2019, 63 hospital organisations provided CTCA-services (93%), CTCA was performed on 99 CTCA-capable CT-scanners, and 37,283 CTCA-examinations were performed. Between the hospital organisations, we found substantial variation considering CTCA indications, CTCA equipment and acquisition and reporting standards. To fully implement the new ESC guideline, our model suggests that 70,000 additional CTCA-examinations would have to be performed in the Netherlands. Conclusions Despite high national CTCA-services coverage in the Netherlands, a substantial increase in CTCA capacity is expected to be able to implement the 2019 ESC-CCS recommendations on the use of CTCA. Furthermore, the results of this survey highlight the importance to address variations in image acquisition and to standardise the interpretation and reporting of CTCA, as well as to establish interdisciplinary collaboration and organisational alignment.

Impact of COVID-19 Measures on a Paediatric Oncology Outreach Program: Medical Perspectives

Background Paediatric oncology outreach programs have been effective development interventions to reduce inequalities in healthcare between high-income countries (HIC) versus low and middle-income countries (LMIC). But little is known about its sustainability during times of a pandemic. This study assesses the impact of COVID-19 government measures on a paediatric oncology outreach program between three large referral hospitals in the Netherlands, Indonesia and Kenya. Methods The head from each paediatric oncology outreach partner site was interviewed using a semi-structured questionnaire in June 2021. Results COVID-19 government measures impacted childhood cancer care at all three hospitals. However, disruptions in services are more prominent at partner sites in LMIC, increasing existing inequalities.The doctor from Dutch hospital, located in a HIC, reported only one disruption which is a decrease in surveillance evaluations for patients who completed cancer treatment. The doctors from Indonesian and Kenyan hospitals, located in LMIC, reported multiple disruptions. For example, reduced number of cancer diagnoses, delayed presentations, medical staff shortages, limited availability of chemotherapy and blood products, and delayed or modified treatment administration. Physical interaction between medical teams of all three participating institutions has slowed down. Hereby, adequate transfer of knowledge, skills and expertise have been adversely affected. Conclusion COVID-19 government measures have negatively impacted the intrinsic nature of the paediatric oncology outreach program. Disruptions in childhood cancer care services are more prominent at partner sites in LMIC. Government leaders and policy makers should take collateral damage of their policies and local settings into account to protect children with cancer

Induction of trained immunity by influenza vaccination - impact on COVID-19

Non-specific protective effects of certain vaccines have been reported, and long-term boosting of innate immunity, termed trained immunity, has been proposed as one of the mechanisms mediating these effects. Several epidemiological studies suggested cross-protection between influenza vaccination and COVID-19. In a large academic Dutch hospital, we found that SARS-CoV-2 infection was less common among employees who had received a previous influenza vaccination: relative risk reductions of 37% and 49% were observed following influenza vaccination during the first and second COVID-19 waves, respectively. The quadrivalent inactivated influenza vaccine induced a trained immunity program that boosted innate immune responses against various viral stimuli and fine-tuned the anti-SARS-CoV-2 response, which may result in better protection against COVID-19. Influenza vaccination led to transcriptional reprogramming of monocytes and reduced systemic inflammation. These epidemiological and immunological data argue for potential benefits of influenza vaccination against COVID-19, and future randomized trials are warranted to test this possibility.

Current Practice of Dutch Hospital-Based Palliative Care Teams: Advance Care Planning in Advanced Stages of Disease

Background: Specialist palliative care teams (PCT) are consulted during hospital admission for advice on complex palliative care. These consultations need to be timely to prevent symptom burden and maintain quality of life. Insight into specialist PCTs may help improve the outcomes of palliative care. Methods: In this retrospective observational study, we analyzed qualitative and quantitative data of palliative care consultations in a six-month period in four general hospitals in the northwestern part of the Netherlands. Data were obtained from electronic medical records. Results: We extracted data from 336 consultations. The most common diagnoses were cancer (54.8%) and organ failure (26.8%). 40.2% of patients were restricted to a chair or bed and 52.3% had an estimated life expectancy of less than three months. Within two weeks after consultation, 53.2% of the patients died, and the median time until death was 11 days (range 191) after consultation. Most patients died in hospital (49.4%) but only 7.5% preferred to die in hospital. Consultations were mostly requested for advance care planning (31.6%). End-of-life preferences focused on last wishes and maintaining quality of life. Conclusion: This study shows that palliative care consultations focus on terminal care and are more crisis-oriented than prevention-oriented. Death often occurs too quickly after consultation for end-of-life preferences to be met and these preferences tend to focus on dying. Educating healthcare professionals on when to initiate palliative care would promote a more prevention-oriented approach. Factors that indicate the need for timely PCT consultation should be defined.

Translation and transcultural validation of the Dutch hospital for special surgery paediatric functional activity brief scale (HSS Pedi-FABS)

Background There is a need for a validated simple Dutch paediatric activity scale. The purpose was to translate and transculturally validate the Dutch Hospital for Special Surgery Paediatric Functional Activity Brief Scale (HSS Pedi-FABS) questionnaire in healthy children and adolescents. Methods The original HSS Pedi-FABS was translated forward and backward and was transculturally adapted after performing a pilot study among children and professionals. The final version of the Dutch HSS Pedi-FABS was validated in healthy children and adolescents aged 10 to 18 years old. Children who had any condition or injury limiting their normal physical activity were excluded. The interval between the first questionnaire T0 (HSS Pedi-FABS, Physical Activity Questionnaire for children or adolescents (PAQ-C/A) and Tegner activity scale) and the second questionnaire T1 (HSS Pedi-FABS) was 2 weeks. Construct validity, interpretability and reliability were evaluated. Content validity was evaluated through cognitive interviews among a smaller group of children and through a questionnaire among professionals. Results To evaluate content validity, 9 children and adolescents were interviewed, and 30 professionals were consulted. Content validity among professionals showed a relevance of less than 85% for most items on construct. However, content validity among children was good with a 92% score for item relevance. Readability was scored at a reading level of 11- to 12-year-olds. The validation group consisted of 110 healthy children and adolescents (mean age of 13.9 years ±2.6). Construct validity was considered good as 8 out of 10 hypotheses were confirmed. The Dutch HSS Pedi-FABS showed no floor or ceiling effect. Analysis of the internal consistency in the validation group resulted in a Cronbach’s alpha of 0.82. Test-retest reliability was evaluated among 69 children and adolescents and revealed an Intraclass Correlation Coefficient (ICC) of 0.76. Conclusion The Dutch HSS Pedi-FABS showed good psychometric properties in a healthy Dutch paediatric and adolescent population. Limitations of the current Dutch HSS Pedi-FABS are content validity on construct of items reported by professionals.

Vitality, resilience and the need for support among hospital employees during the COVID-19 pandemic: study protocol of a mixed-methods study

IntroductionThe COVID-19 pandemic has had a significant impact on the physical and mental functioning of healthcare professionals, especially those working on the ‘frontline’, and other hospital workers. At the onset of the crisis, various interventions were introduced to promote resilience and offer mental support to these professionals. However, it is unknown whether the interventions will meet the needs of professionals as the COVID-19 pandemic continues.The goal of this exploratory study is to gain insight in factors that protect the vitality and resilience of Dutch hospital employees during the so-called ‘second wave’ of the COVID-19 pandemic. This paper describes the study protocol.Methods and analysisThis exploratory study applies a mixed-methods design, using both quantitative and qualitative methods of data collection and analysis. The first part of the study (substudy I) consists of surveys among doctors and nurses in COVID-19 departments and non-COVID-19 departments, and other professionals in the hospital (ie, managers and homeworkers) in 2020 and 2021. The second part of the study (substudy II) consists of focus groups and interviews among professionals of the intensive care unit, COVID-19 departments and infection prevention units.Ethics and disseminationThe research protocol for this study has been approved by the Medical Ethics Committee (MEC-2020-0705). The outcomes of this study will be used to develop and implement interventions to support hospital employees maintaining their vitality and resilience during and after the COVID-19 pandemic. Employees with vitality experience less work-related stress and make a positive contribution to healthcare quality.

Preparations of Dutch emergency departments for the COVID-19 pandemic: A questionnaire-based study

Background The onset of the COVID-19 pandemic was characterized by rapid increases in Emergency department (ED) patient visits. EDs required an appropriate transformation. The main challenges were: adapting capacity to respond to surges in the number of patient visits, protection of high risk (frontline) staff and the segregation of suspect-COVID-19 patients. To date, only a few studies have assessed the nation-wide response of EDs to the COVID-19 pandemic. This study was designed to review the preparations of Dutch EDs during the initial phase of this public health crisis. Methods The study was designed as a nation-wide, cross-sectional, questionnaire-based study of Dutch hospital organizations having one or more EDs. One respondent completed the questionnaire for each hospital. The questionnaire was conducted between the first and the second COVID-19 wave in the Netherlands. It contained close-ended and open-ended questions on changes in ED infrastructure, ED workforce adaptions and the role of emergency physicians (EPs) in each hospital crisis management team. Results The questionnaire was completed by 58 respondents. This represented 80% of the total number of EDs. All respondents had made preparations in anticipation of a COVID-19 patient surge. Treatment capacity was expanded in 70% of EDs, with a median increase of 49% (IQR 33–73%). Suspect-COVID-19 was segregated from non-COVID-19 patients in 89% of EDs. Alternative locations (such as outpatient departments) were more often used to assess non-COVID-19 patients, than for suspect-COVID-19 patients. Staff was expanded in 82% of EDs. This largely concerned nursing staff. A formal role for Emergency Physicians (EPs) in the hospital’s crisis management team was reported by 94% of hospital organizations employing EPs. Conclusion All Dutch EDs responded to the COVID-19 pandemic in a very short time span despite much uncertainty. Preparations predominantly concerned expansion of treatment capacity and segregation of COVID-19 ED care. EPs played a prominent role, both in direct COVID-19 care and in the hospital crises management team. It is vital for EDs to adapt to community needs swiftly. The ability of EDs to respond to the pandemic varied considerably.

COVID outcome prediction in the emergency department (COPE): using retrospective Dutch hospital data to develop simple and valid models for predicting mortality and need for intensive care unit admission in patients who present at the emergency department with suspected COVID-19

ObjectivesDevelop simple and valid models for predicting mortality and need for intensive care unit (ICU) admission in patients who present at the emergency department (ED) with suspected COVID-19.DesignRetrospective.SettingSecondary care in four large Dutch hospitals.ParticipantsPatients who presented at the ED and were admitted to hospital with suspected COVID-19. We used 5831 first-wave patients who presented between March and August 2020 for model development and 3252 second-wave patients who presented between September and December 2020 for model validation.Outcome measuresWe developed separate logistic regression models for in-hospital death and for need for ICU admission, both within 28 days after hospital admission. Based on prior literature, we considered quickly and objectively obtainable patient characteristics, vital parameters and blood test values as predictors. We assessed model performance by the area under the receiver operating characteristic curve (AUC) and by calibration plots.ResultsOf 5831 first-wave patients, 629 (10.8%) died within 28 days after admission. ICU admission was fully recorded for 2633 first-wave patients in 2 hospitals, with 214 (8.1%) ICU admissions within 28 days. A simple model—COVID outcome prediction in the emergency department (COPE)—with age, respiratory rate, C reactive protein, lactate dehydrogenase, albumin and urea captured most of the ability to predict death. COPE was well calibrated and showed good discrimination for mortality in second-wave patients (AUC in four hospitals: 0.82 (95% CI 0.78 to 0.86); 0.82 (95% CI 0.74 to 0.90); 0.79 (95% CI 0.70 to 0.88); 0.83 (95% CI 0.79 to 0.86)). COPE was also able to identify patients at high risk of needing ICU admission in second-wave patients (AUC in two hospitals: 0.84 (95% CI 0.78 to 0.90); 0.81 (95% CI 0.66 to 0.95)).ConclusionsCOPE is a simple tool that is well able to predict mortality and need for ICU admission in patients who present to the ED with suspected COVID-19 and may help patients and doctors in decision making.
