title: Benign paroxysmal positional vertigo: opportunities squandered.
abstract: Benign paroxysmal positional vertigo (BPPV) presentations are unique opportunities to simultaneously improve the effectiveness and efficiency of care. The test and treatment for BPPV--the Dix-Hallpike test (DHT) and the canalith repositioning maneuver (CRM), respectively--are supported by two evidence-based guidelines (American Academy of Otolaryngology--Head and Neck Surgery and American Academy of Neurology). With these processes, patients can be readily identified and treated at the bedside, quickly and without expensive tests. Patients randomized to the CRM have a cure rate of 80% at 24 h, compared to only 10% of controls. Despite this large effect size, less than 10% of affected patients receive the treatment, which shows that the management of BPPV in routine care is suboptimal. Future research is necessary to disseminate and implement the DHT and the CRM into routine practice.
