A simple protocol avoids unnecessary invasive proceduresMay 18, 2006When a patient comes to the emergency room with a severe headache, this may be a sign of a Subarachnoid Hemorrhage (SAH), an extremely serious condition caused by a bleeding brain aneurysm. On the other hand, there may be less threatening explanations for the pain. Until now, there has been no way to rule out the more serious condition and a series of tests involving some risk to the patient would have had to be done. In a paper presented at the 2006 Society for Academic Emergency Medicine Annual Meeting, May 18-21, 2006 in San Francisco, a group of Canadian researchers reported on their investigation of a protocol which could minimize invasive testing. In a study conducted at 6 university Emergency Departments involving nearly 2000 patients, 80% underwent head computed tomography (CT), 45% received lumbar puncture (LP, i.e. a spinal tap), 83% had either CT and/or LP, and 6.4% had a final diagnosis of SAH. By using 4 simple clinical observations, the authors were able to predict whether a patient was at high risk for SAH. For example, of those who arrived by ambulance, 57% were later diagnosed with SAH, while only 17% of those who arrived by ambulance did not have SAH. Vomiting was a symptom in 58% of the patients with SAH and only in 26% of those without SAH. A diastolic blood pressure "100mmHg or age 45" were also strong predictors of SAH.
By using these simple observations, the authors developed a clinical rule that any patient showing 1 or more of these symptoms would then be a candidate for further investigation, via CT and/or LP. This rule would identify all the patients with SAH, while reducing the investigation rate to 66%. According to Jeffrey Perry, MD, "While we do not recommend an immediate change in management until after a validation study is complete, this study will have a tremendous impact on patient care. It will improve our ability to determine which patients require investigations for their headache and which ones just need pain control without costly and invasive testing."
