[Management and improvement of the process of outpatient treatment of transient ischemic attacks in Neurology departments].

AIMS
To describe our experience in the ambulatory treatment of transient ischemic attacks (TIA) in a second-level hospital with the implementation of an example of process management within the different services involved in attending such conditions.


PATIENTS AND METHODS
The following aspects of the process--mission, limits, flowchart, eligibility criteria and performance indicators (process, sentinel and effectiveness)--were defined by multidisciplinary consensus (Emergency, Vascular Surgery, Cardiology, Neurology and Radiology departments). This process was implemented from April 2002 to May 2004, and monthly assessments were carried out to check for problems and to introduce corrective measures. After ending the process, patients with TIA were admitted as inpatients for a hospital study.


RESULTS
Definition of the process: medical care (diagnosis and treatment) of TIA patients who are eligible for a complete outpatient study within seven days. Patients evaluated: 254. Indicator 1 (percentage of suitable referrals): 2002: 53%, 2003: 75%, 2004: 73%. Indicator 2 (percentage of complete studies in less than one week): 2002: 35%, 2003: 57%, 2004: 50%; hospitalised: 90%. Indicator 3 (infarcts during the study): 2002: 4.3%, 2003: 0%, 2004: 0%; hospitalised: 0%. Indicator 4 (percentage of adjustments made to treatment): 2002: 39%, 2003: 31%, 2004: 62%; hospitalised: 72%. Mean delay before visit: in February 2002: 90 days, in April 2002: 7.67 days and in April 2003: 5.37. Problems detected: delays in referrals, failure to fit hospitalisation criteria, delays in carrying out examinations not included in the protocol, unsuitable indicator design. Steps taken: redefinition of indicators, modification of the referral system, adjustments made to the circuits involved in carrying out tests, review of hospitalisation criteria.


CONCLUSIONS
Process management is an ideal tool for achieving ongoing improvements in clinical praxis. Early monitoring makes it possible to detect problems and to implement corrective measures. In our area, the study of TIA must be performed in a hospital inpatient regimen in order to comply with the guidelines for clinical practice.
