Disease control in chronic rhinosinusitis: a qualitative study of patient perspectives.

BACKGROUND: The definition of disease control in chronic rhinosinusitis (CRS) is an active area of study. However, investigations have not engaged CRS patients in how they think about disease control. This study seeks to understand the patient perspective on CRS disease control. METHODS: Qualitative phenomenological study using constant comparative methodology was applied. The research team conducted 10, one-on-one interviews with CRS patients ranging from 22 to 55 minutes in length. The content of the interview protocol was determined through iterative discussion amongst all authors. Two authors served as coders to identify recurrent themes. Themes were analyzed for meaning and conclusions were summarized. RESULTS: Three recurring themes determined from patients were that (1) use of the terminology control adequately represents this phenomenon, (2) components of control could be classified into four main themes relating to CRS symptomatology, exacerbation of comorbid disease, quality of life and acute exacerbations of CRS, and (3) when patients deem their CRS is uncontrolled they are more willing to escalate their treatment to include escalating their daily maintenance regimen, seeking otolaryngology referral, taking rescue medication or undergoing endoscopic sinus surgery. CONCLUSIONS: CRS patients consider their daily symptoms, the severity and frequency of CRS exacerbations, impact on quality of life as well as exacerbation of comorbid disease when thinking about their disease control. Disease control is a goal of treatment for patients and uncontrolled disease motivates patients to seek further treatment. Physicians should explore all components of CRS control when considering disease status and need for further treatment.

[Olfactory and gustatory disorders]. / Riech- und Schmeckstörungen.

This manuscript aims to provide an overview of the etiology and diagnosis of olfactory and gustatory disorders. Not only are they common with about 5% of the population affected, but olfactory and gustatory disorders have recently gained attention in light of the rising SARS-CoV­2 pandemic: sudden loss of smell and/or taste is regarded as one of the cardinal symptoms. Furthermore, in the early diagnostics of neurodegenerative diseases, olfactory disorders are of great importance. Patients with olfactory dysfunction often show signs of depression. The impact of olfactory/gustatory disorders is thus considerable, but therapeutic options are unfortunately still limited. Following a description of the etiology, the diagnostic and therapeutic options are discussed on the basis of current literature. Potential future treatments are also addressed, e.g. autologous mucosal grafts or olfactory implants.

EPOS 4 Patients.

EPOS2020 is the 4th and most recent version of the European Position Paper on Rhinosinusitis and Nasal Polyps which was first published in 2005. It aims to provide the most up to date scientifically robust information on the topic published in the literature which has been critically analysed by an international group of clinicians drawn from all disciplines dealing with these problems together with patients. The guidelines offer evidence-based recommendations and care pathways for acute and chronic rhinosinusitis in both adults and children. Management of these diseases from the patients' perspective is an important part of EPOS2020. Not only is this included in the main document but, for the first time, we have produced a separate supplement dedicated to and in collaboration with patients, EPOS4Patients, which aims to provide information in an accessible format, to answer frequently asked questions about these diseases and their treatment options as well as including useful patient resources and websites. It has never been more important for patients to be actively involved in their care. Being well informed helps you to make the best decisions together with your doctor.

Individual importance of olfaction decreases with duration of smell loss.

BACKGROUND: The personal importance of a lost neurologic - motor or sensory - function in several conditions has been shown to decrease as the afflicted patient becomes accustomed to not having that function. It is unknown how the importance of olfaction changes with duration of olfactory dysfunction (OD). The aim of this study was to evaluate the association between duration of smell loss and individual significance of olfaction, and whether this relationship would be modulated by other factors, such as etiology of smell loss. METHODS: This is a retrospective study including a total 163 subjects with different degrees of olfactory function. Individual significance of olfaction was measured using the Importance of Olfaction Questionnaire (IOQ). Demographics, olfactory function, duration and etiology of OD were evaluated. Group comparisons, bivariate correlations, analyses of variance and multivariate linear regression were applied to detect differences and associations with the outcome measure of IOQ. RESULTS: A significant negative correlation was found between duration of OD and the IOQ. Other important findings include a significantly higher IOQ in patients with posttraumatic- compared to idiopathic OD and in patients with higher aggravation scores compared to the lower aggravation group. Multivariate regression analysis further confirmed that duration of smell loss was independently associated with IOQ. CONCLUSIONS: The duration of smell loss is negatively correlated with the individual importance of olfaction, suggesting that patients develop coping mechanisms for adjusting to OD.

Validity of systemic antibiotics and systemic corticosteroid usage for chronic rhinosinusitis as metrics of disease burden.

BACKGROUND: The frequencies of systemic antibiotics and oral corticosteroids taken for chronic rhinosinusitis (CRS) indicate poor CRS disease control. We sought to determine the validity and responsiveness of these metrics as reflections of CRS disease burden. METHODOLOGY: One hundred and eighty-seven patients undergoing medical management for CRS were recruited. Participants were assessed at two time points: enrollment and a follow-up appointment three to nine months later. At each time point, CRS related antibiotic and oral corticosteroid usage in the previous three months was measured, while general and disease-specific quality of life (QOL) was measured using the visual analog scale of the 5-dimension EuroQol questionnaire (EQ-5D VAS) and the 22-item Sinonasal Outcome Test (SNOT-22), respectively. RESULTS: The frequency of CRS-related antibiotics and oral corticosteroids use was cross-sectionally correlated with EQ-5D VAS and SNOT-22 at the corresponding time points. For participants reporting usage of these medications at enrollment, there was a decrease of 1 course per 3 months for both CRS-related antibiotics and oral corticosteroids. Change in CRS-related antibiotics from enrollment to follow-up was correlated with change in both EQ-5D and SNOT-22 over the same timeframe. The change in CRSrelated oral corticosteroids was correlated with change in both EQ-5D VAS and SNOT-22). These correlations were stronger in the subset of patients who had a change in these metrics over the study period. CONCLUSIONS: The frequencies of CRS-related antibiotic use and oral corticosteroid use are valid and responsive measures of CRS disease burden.

Responsiveness and minimal clinically important difference for the EQ-5D in chronic rhinosinusitis.

BACKGROUND: The 5-dimensional EuroQol questionnaire (EQ-5D) is validated to measure general health-related quality of life (QOL). Our objective was to determine the responsiveness and minimal clinically important difference (MCID) of the EQ-5D health utility value (EQ-5D HUV) and visual analog scale (EQ-5D VAS) in chronic rhinosinusitis (CRS). METHODS: 203 adults undergoing medical management for CRS were prospectively recruited. General health-related QOL (using EQ-5D HUV and EQ-5D VAS) and CRS-specific QOL (using the 22-item Sinonasal Outcome Test [SNOT-22]) were measured at enrollment and a subsequent follow-up time point 2-12 months later. At follow-up, participants also rated change in general health as Much worse, A little worse, About the same, A little better or Much better compared to enrollment. The EQ-5D HUV and EQ-5D VAS MCIDs were calculated using distribution-based, anchor-based, and receiver operator characteristic (ROC) curve-based methods. RESULTS: Change in SNOT-22 score was correlated with EQ-5D HUV and EQ-5D VAS change. Using the different methods of calculating MCID, we find the EQ-5D HUV MCID to be 0.04 and EQ-5D VAS MCID to be 8.0. The calculated EQ-5D MCIDs had approximately a sensitivity of 40-50% and specificity of 80% in detecting patients experiencing noticeable improvement in general health. CONCLUSIONS: The EQ-5D responds well to changing CRS symptomatology. We propose MCIDs for EQ-5D HUV of 0.04 and EQ-5D VAS of 8 in CRS patients, which although specific, are not sensitive for detecting patients experiencing improvement in general health.
