An analysis of referral patterns for dizziness in the primary care setting.

BACKGROUND: The majority of balance disorders are non life-threatening and symptoms will resolve spontaneously. However, some patients require further investigation and many disorders may benefit from specialist treatment it is unclear whether appropriate identification and referral of this group of patients presently occurs. AIM: To review the management of patients with symptoms of dizziness within primary care.
METHOD: A retrospective review of the management of 503 patients who visited their general practitioner (GP) complaining of dizziness between August 1993 and July 1995. Management was then compared with local criteria.
RESULTS: On average, 2.2% of patients per year at the practices studied consulted their GP about dizziness, amounting to 0.7% of all consultations. The most common GP diagnosis was of an ear, nose, and throat (ENT) disorder (33.8%). Similarly, many of the 16% referred were directed to ENT (36%) specialists. The proportion of patients referred was significantly higher in those seeing their GP at least twice, those with symptoms lasting a year or more, or where there were additional symptoms associated with the dizziness, indicative of a cardiac, ENT, or neurological disorder. Compared with the local criteria, 17% of management decisions were deemed inappropriate. The major failing was not referring appropriate patients. This group comprised patients with chronic, non-urgent symptoms, and were significantly older than those appropriately referred.
CONCLUSION: Patients with chronic symptoms of dizziness, particularly the elderly, are under-referred for specialist consultation and, therefore, do not have access to appropriate treatment regimes. This suggests a need for further training of GPs and evaluation of therapeutic needs of elderly dizzy patients.
