“…Olfactory evaluation, however, is not common in routine health assessments. From our findings, clinicians could ask current and perceived changes in smell and flavor to identify severe olfactory dysfunction and could follow up with additional assessments (Croy et al 2011; Pusswald et al 2012) and evaluation if the dysfunction interferes with health, nutritional status, and/or well-being (quality of life). There are many qualitative aspects of smell impairments, such as presence of phantom or distorted smells, which are not captured by routine olfactory testing.…”

Introduction The 2011–14 US National Health and Nutrition Examination Survey chemosensory protocol asks adults to self-rate their orthonasal (via nostrils) and retronasal (via mouth) smell abilities for subsequent odor identification testing. From data collected with a similar protocol, we aimed to identify a self-reported olfactory index that showed the best sensitivity (correctly identifying dysfunction) and specificity (correctly indentifying normosmia) with measured olfaction. Methods In home-based testing, 121 independent-living older women (age 73±7 years) reported their olfactory function by interviewer-administered survey. Olfactory function was measured orthonasally via composite (odor threshold, identification task) or identification task alone. Results Only 16 % of women self-rated “below average” smell function. More women perceived loss of smell (38 %) or flavor (30 %) with aging. The rate of measured dysfunction was 30 % by composite (threshold and identification) and 21.5 % by identification task, the latter misclassifying some mild dysfunction as normosmia. An index of self-rated smell function and perceived loss yielded the most favorable sensitivity (65 %) and specificity (77 %) to measured function. Self-rated olfaction showed better agreement with severe measured dysfunction; mild dysfunction was less noticed. Conclusions Self-reported indices that query about current and perceived changes in smell and flavor with aging showed better sensitivity estimates than those previously reported. Specificity was somewhat lower—some older adults may correctly perceive loss unidentified in a single assessment, or have a retronasal impairment that was undetected by an orthonasal measure. Implications Our findings should inform self-rated measures that screen for severe olfactory dysfunction in clinical/community settings where testing is not routine.

“…Usually patients with olfactory loss attach less importance to their current sense of smell in daily life than do individuals with normal olfactory function. 22 Although these individuals adapt, the scope of olfactory sensing is restricted by the degree of olfactory loss. We thought that this restricted olfactory scope is the reason why BDI scores were inversely correlated with TDI scores There was a statistically significant correlation.…”

“…Neuland et al 36 found that patients with congenital anosmia indicated no loss (0%) in QoL, while acquired hyposmia affected QoL more than acquired anosmia. Croy et al 37 reported that patients with OD duration of more than 1 year tended to use their sense of olfaction less often than patients with shorter disorder duration, indicating adjustment.…”

Introduction: Olfactory dysfunction (OD) is a frequent medical condition which might determine an important reduction of the patient's quality of life (QoL). The analysis of OD-related QoL may play an important role in clinical practice since the patient's perspectives may influence clinical decisions and could be used to monitor the longitudinal course of individual outcomes. Evidence acquisition: Only a limited number of specific instrument able to evaluate OD-related QoL have been proposed so far and their clinical application is limited. The aim of this review was to analyze the available instruments useful for OD-related QoL measurement in order to increase clinicians' awareness of OD and their ability to evaluate its impact. Evidence synthesis: The Questionnaire of Olfactory Disorders (QOD) is the more widely used but its internal consistency is poor. The Importance of Olfaction Questionnaire demonstrated a good internal consistency but no information regarding its reliability are available. The Self-Administered Odor Questionnaire (SAOQ) demonstrated satisfactory clinical validity and responsiveness to changes but no information regarding its internal consistency and reliability are available. The Scandinavian adaptation of the Multi-Clinic Smell and Taste Questionnaire (MCSTQ-Sc) appears too time consuming. Finally, the Modified Short version of the QOD (MS-QOD) demonstrated satisfactory internal consistency, optimal test re-test reliability and satisfactory discriminant and convergent validity. Conclusions: There is a need for a psychometrically robust, time-and cost-efficient, easy-to-use instrument to be used in everyday clinical practice for the evaluation of the impact of OD on patient's QoL
