Introduction. Neurology consultations requested by other services in in-patients are performed through intrahospital consultations. This study aims to make a descriptive study of the intrahospital consultations (IHC) requests received by a Neurology service. Material and methods. We conducted a retrospective study of the requests for consultations received in the Neurology Service in the Hospital Universitario Clínico San Carlos in Madrid during the year 2007. The following endpoints were analyzed: number of consultations, number of visits made, date, delay in attention, specialties involved, syndromic diagnosis, final diagnosis and complementary tests requested. Results. A total of 390 intrahospital consultations corresponding to 351 patients were made. Total number of visits was 687. Internal Medicine was the specialty making the most requests with 31%, followed by Psychiatry (13.4 %) and Oncology (8 %). The most frequent syndromic diagnoses were neurological deficit (31.6%), seizures (18.2%) and awareness level disturbance (11.7%). The most frequent final diagnoses were epilepsy (19.9 %), cerebrovascular disease (15%) and movement disorders (10.5 %). Complementary tests were requested for 37% of the patients, the most common ones being cranial and spinal magnetic resonance imaging, Head CT and EEG. Conclusions. Because of its complexity and care load, intrahospital consultation should be considered an independent unit in the organization of a neurological service. As it involves a significant number of patients, it should be subject to evaluation and quality improvement programs.
