Show moreBackground: In the Netherlands, the COVID-19 pandemic resulted in a temporary halt of population screening for cancer and limited hospital capacity for non-COVID care. We aimed to investigate the impact of the pandemic on the in-hospital diagnostic pathway of breast cancer (BC) and colorectal cancer (CRC).Methods: 71,159 BC and 48,900 CRC patients were selected from the Netherlands Cancer Registry. Patients, diagnosed between January 2020 and July 2021, were divided into six periods and compared to the average of patients diagnosed in the same periods in 2017-2019. Diagnostic procedures performed were analysed using logistic regression. Lead time of the diagnostic pathway was analysed using Cox regression. Analyses were stratified for cancer type and corrected for age, sex (only CRC), stage and region.Results: For BC, less mammograms were performed during the first recovery period in 2020. More PET-CTs were performed during the first peak, first recovery and third peak period. For CRC, less ultrasounds and more CT scans and MRIs were performed during the first peak. Lead time decreased the most during the first peak by 2 days (BC) and 8 days (CRC). Significantly fewer patients, mainly in lower stages, were diagnosed with BC (-47%) and CRC (-36%) during the first peak.Conclusion: Significant impact of the COVID-19 pandemic was found on the diagnostic pathway, mainly during the first peak. In 2021, care returned to the same standards as before the pandemic. Long-term effects on patient outcomes are not known yet and will be the subject of future research. Show less

Show moreObjectives: Hypertension is a common cause of cardiovascular morbidity and mortality. Although hypertension can be effectively controlled by blood pressure-lowering drugs, uncontrolled blood pressure is common despite use of these medications. One explanation is therapy non-adherence. Therapy non-adherence can be addressed at the individual level, the level of the healthcare provider and at the healthcare system level. Since the latter two levels are often overlooked, we wished to explore facilitators and barriers on each of these levels in relation to hypertension care for people with hypertension, with a specific focus on therapy adherence. Design: Qualitative study using focus groups of healthcare providers. Data were analysed using the theoretical domains framework (TDF) and the behaviour change wheel. Setting and participants: Participants were from a highly urbanised city environment (the Hague, Netherlands), and included nine primary care physicians, six practice nurses and five secondary care physicians involved in hypertension care. Results: Nine domains on the TDF were found to be relevant at the healthcare provider level ('knowledge', 'physical, cognitive and interpersonal skills', 'memory, attention and decision processes', 'professional, social role and identity', 'optimism', 'beliefs about consequences', 'intention', 'emotion' and 'social influences') and two domains ('resources' and 'goals') were found to be relevant at the system level. Facilitators for these domains were good interpersonal skills, paying attention to behavioural factors such as medication use, and the belief that treatment improves health outcomes. Barriers were related to time, interdisciplinary collaboration, technical and financial issues, availability of blood pressure devices and education of people with hypertension. Conclusions: This study highlighted a need for better collaboration between primary and secondary care, for more team-based care including pharmacists and social workers, tools to improve interpersonal skills and more time for patient-healthcare provider communication.

Show moreObjective To study the optimal cut-off value for anti-tissue transglutaminase type 2 IgA antibodies (TG2A) in serum to select for diagnostic small bowel biopsies for celiac disease in children with type 1 diabetes mellitus.Study design Children with type 1 diabetes mellitus with elevated TG2A titers and duodenal biopsies performed during the course of their diabetes treatment were included. Anti-endomysial antibodies were recorded if present. The optimal TG2A cut-off value, expressed as the ratio between obtained value and upper limit of normal (ULN), was determined using receiver operating characteristic curve analysis and compared with the cut-off value used in the European Society for Pediatric Gastroenterology, Hepatology and Nutrition guidelines in terms of sensitivity, specificity, positive and negative predictive value.Results We included 63 children. The optimal cut-off value for performing biopsies is demonstrated to be 11 times the ULN. Raising the cut-off value from 3 times the ULN to 11 times the ULN changed sensitivity from 96% to 87% and increased specificity from 36% to 73%, increased the positive predictive value from 88% to 94% and lowered negative predictive value from 67% to 53%. The percentage of normal histology was decreased from 12% to 6%.Conclusions Increasing the TG2A cut-off value for performing duodenal biopsies in children with type 1 diabetes mellitus and suspected celiac disease leads to a substantial reduction of unnecessary biopsies. We advocate to adapt the European Society for Pediatric Gastroenterology, Hepatology and Nutrition 2012 guidelines for this group of children, including monitoring patients with TG2A levels of less than 11 times the ULN over time.
