Abstract
This case–control study aimed to investigate the association of peripheral vestibular disorders (PVD) with subsequent land transport accidents. Data for this study were obtained from Taiwan’s National Health Insurance (NHI) dataset. We retrieved 8704 subjects who were newly found to have land transport accidents as cases. Their diagnosis date was used as their index date. Controls were identified by propensity score matching (one per case, n = 8704 controls) from the NHI dataset with their index date being the date of their first health service claim in 2017. Multiple logistic regressions were performed to calculate the prior PVD odds ratio of cases vs. controls. We found that 2.36% of the sampled patients had been diagnosed with PVD before the index date, 3.37% among cases and 1.36% among controls. Chi-square test revealed that there was a significant association between land transport accident and PVD (p < 0.001). Furthermore, multiple logistic regression analysis suggested that cases were more likely to have had a prior PVD diagnosis when compared to controls (OR = 2.533; 95% CI = 2.041–3.143; p < 0.001). After adjusting for age, gender, hypertension, diabetes, coronary heart disease, and hyperlipidemia, cases had a greater tendency to have a prior diagnosis of PVD than controls (OR = 3.001, 95% CI = 2.410–3.741, p < 0.001). We conclude that patients with PVD are at twofold higher odds for land transport accidents.
Highlights
We found that after using propensity score matching, there were significant differences between patients who had received a diagnosis of land transport accident and controls regarding age (p < 0.001), gender (p = 0.025), monthly income (p < 0.001), geographic location (p < 0.001), and residential urbanization level (p < 0.001)
Because we used propensity score matched controls, it was expected that we would find small but statistically significant differences in the variables used to match controls with patients who had received a diagnosis of land transport accident
The mean age was 43.21 and 45.68 years for patients who had received a diagnosis of land transport accident and controls, respectively
Summary
Peripheral vestibular disorders (PVD) are very common in clinic settings [1] with an estimated one-year prevalence of 1.2–6.5% in the adult population [2]. The disease entity comes from mismatched sensations of vestibular afferents, the visual system, and somatosensory and proprioceptive receptors with a plethora of pathogenesis, including. Meniere’s disease (MD), benign paroxysmal positional vertigo (BPPV), vestibular neuritis (VN), and other or unspecified peripheral vestibular dizziness. Vestibular function is involved in spatial orientation and navigation [3,4]. Patients with PVD often experience vertigo as a hallucination of motion; some describe this as self-motion and others as motion
