[Delayed diagnosis of benign paroxysmal vertigo: economic impact].

Some time has passed since the early 1980's when a group of vestibologists with the same singular passion introduced in Italy the concept of Paroxysmal Positional Vertigo (PPV). Since then great advances have been made, but, despite the energy focused on improving and expanding the knowledge on this common disorder, PPV still frequently goes unrecognized. The direct consequence of delayed diagnosis is prolonged patient discomfort and the execution of useless, costly clinical examinations. Today, in most cases, delayed diagnosis is unjustified. Within the modern concept of health care economics, such delay is costly to the health care provider and has obvious psycho-physical repercussions for the patient who has to undergo a fruitless series of examinations and treatments of all types without reaping any benefits. In this light the Authors have performed a study to identify and quantify the relative costs of the most common errors made in the diagnosis of PPV. For a sample population of 100 patients, the clinical-instrumental tests performed before the disorder was correctly diagnosed were gathered and analyzed. Then the costs for the management of PPV patients diagnosed late were compared with those for patients whose diagnosis was reached early on. The results indicate that for each delay in PPV diagnosis the average cost was Euro 317.66 vs. Euro 64.04 for early diagnosis: a difference of Euro 253.06. The Authors underline how in this brief period of time (March-September 2000) the prescription of excessive testing led to a significant waste of money (Euro 10137.01).
