This questionnaire was developed for the EPOCHAL study (Effects of Pollen on Cardiorespiratory Health and Allergic symptoms). The study was sponsored and led by Swiss TPH in Basel, Switzerland and approved by the local ethics committee (Ethikkomission Nordwest- und Zentralschweiz EKNZ, project ID 2021-00151). Written informed consent was obtained from every participant prior to study inclusion. This is the "nurse home visit form" which was administered 6 times for each participant during weekly home visits by our study nurses during the pollen season. It includes questions about the following topics: 1) Potential for Covid-19 infection, changes in vaccination status 2) Overall health status 3) Allergic symptoms: nose, eyes, lungs 4) Sleep, mood and quality of life 5) Medication use 6) Time spent outdoors 7) Daily covariate information: coffee and alcohol intake, eating, smoking, vigorous exercise 8) Blood pressure measurements 9) Heart rate variability recording 10) Exhaled nitric oxide measurements 11) Pulmonary function testing (spirometry) 12) Comments The questionnaire is also available in German under the same DOI. Please note that this questionnaire was administered electronically on a tablet, and contains: Form logic, which determines the relevance of some questions based on previous answers. Affected questions are typically shown in grey color. Instructions (in bold blue font) to the participant/study nurse to guide the process of data collection (e.g. “please hand over the tablet to the participant/nurse”). Warnings (in large red font) and directions (in large grey font) to warn nurses against performance of spirometry measurements if contraindications were present. For example, when the nurse entered high blood pressure in Topic #8, or when recent surgery was indicated in Topic #11. Warnings and directions also flag incidental findings (e.g., high blood pressure ≥160 mmHg (systolic) or ≥100 mmHg (diastolic) requiring urgent action.
