[Variability in hospital care. Nasosinus surgery in Spain].

Objectives: To describe variations in the management of nasosinus disorders among the Autonomous Communities and hospitals of Spain.

Methods: We analyzed the Minimum Basic Data Set of the public health system from 1998-2000 for the diagnoses of nasosinus polyps and chronic sinusitis. We studied the distribution by regions of the rate of hospitalizations and of 4 indicators of quality of care and efficiency: mean length of stay, percentage of discharges without surgery, percentage of functional endoscopic sinus surgery and surgical complications.
