Disparities in seeking care for olfactory and gustatory dysfunction: A population analysis

Despite effects on quality of life from olfactory and gustatory dysfunction (OD and GD), screening practices are limited, and patients' self-reporting of symptoms remains the only way to understand the burden of chemosensory dysfunction (CSD). Using a large population-based database, we sought to understand factors leading to reduced likelihood of discussing CSD with a provider.

The 2013‒2014 National Health and Nutrition Examination Survey (NHANES) chemosensory protocol was queried for factors influencing discussion of OD/GD with a healthcare provider. Sociodemographic, comorbidity, and objective OD/GD testing results were assessed with a multivariate analysis.

Out of 146.1 million US adults, there were an estimated 41.4 million individuals with self-reported OD/GD in the prior 12 months (28.3%). A total of 86.8% of participants did not discuss their problem with a healthcare provider. Men were about half as likely to speak with a healthcare provider (odds ratio [OR] 0.42; 0.26-0.66; p < 0.001) and those with a college education were about nine times more likely to discuss the problem compared to those with less than a ninth-grade educational achievement (OR 8.83; 1.86-41.98; p = 0.02). Those with objective confirmation of CSD were still unlikely to speak with a provider (OR 0.77; 0.44-1.33; p = 0.36).

Men and those with less education are less likely to discuss OD/GD with a healthcare provider. These populations tend to be at increased risk for CSD, and there are severe downstream health and quality of life implications related to CSD. Dedicated screening and increased public awareness are critical to ensure more equitable care.
