Ecological momentary assessment of outcomes in allergic rhinitis and chronic rhinosinusitis: A review.

backgroundAllergic rhinitis (AR) and chronic rhinosinusitis (CRS) rely on patient-reported symptoms and quality-of-life measures, which are subject to bias. Ecological momentary assessment (EMA) captures data in real time through repeated short surveys, thus reducing errors/biases. EMA's use in sinonasal conditions has not been well described, and the goal of this study was to examine the literature on EMA and AR/CRS. 

methodsA literature review was performed using the following search terms: AR, CRS, and EMA. Inclusion criteria were the use of EMA reporting of sinonasal symptoms at more than one time point. Systematic reviews and non-full text articles were excluded. Population demographics, sinonasal disease, type of EMA platform used, type and severity of symptoms reported, medication use and symptom correlation with location/pollen/pollution were collected.

resultsEight studies met the inclusion criteria, and all focused on AR. All studies were conducted outside the United States in both children and adults. Seven studies used a smartphone application for reporting symptoms, and one used WeChat surveys. EMA data collection varied, with repetitive survey intervals determined either by patients (n = 6) or research team (n = 2). All studies reported sinonasal severity scores, while six reported additional symptoms (e.g., ocular, pulmonary, sleep, general health). Five collected self-reported allergy medication use. Seven studies correlated symptoms with location, pollen, or pollution.

conclusionsFew studies in AR and no studies in CRS assessed the use of EMA. EMA may provide a better understanding of the real-time relationship of environmental triggers with symptoms, in turn guiding treatment decisions.
