title: [The use of thoracic radiography in a third-level-care pediatric hospital].
abstract: OBJECTIVE
  1. To describe the frequency in which the thorax radiography is requested in a third-level pediatric hospital, 2. To identify the frequency of detected abnormalities in such a study by the radiology service, 3. To describe the frequency and the characteristics form the information considered as useful in a clinical way, not only in the radiography application but in the radiologic report and the clinical file as well, 4. To identify the frequency in which the thorax radiography result is associated with diagnosis changes and/or therapeutic ones. DESIGN OF THE INVESTIGATION: Descriptive survey.
  
  
  METHODS
  371 thorax X-rays completed during December 1990 and January 1991.
  
  
  RESULTS
  The thorax radiographies were 32% of the entire radiological study during the survey; 335 of the latter ones (90%) were requested for inpatients. The hospital services which had the highest request for such a study were the Intensive Care Unit (n = 149, 40%) and Medical Pediatrics (n = 116, 31%). The most frequent diagnosis leading to the application was pneumonia (n = 55, 15%) and solid neoplasia (n = 51, 14%). Three-hundred forty eight of the applications had diagnostic impression given by the physician in charge(94%); whereas only 127 (34%) mentioned clinical data. The radiology report was attached to the file in 162 (44%) of the cases. It was found that form the patients who had a radiology report and the thorax radiography as an initial study (n = 95), 48 (50%) suffered from abnormalities. The results of the study were transcribed in the file in 58 cases (16%); the physician's interpretation was written down in 229 cases (62%) and in 84 studies (23%) there was no reference to the results of the study (P < 0.0001). Changes in the therapeutic plan of 93 cases (50%) were identified from the studies with official report by the radiologist, other radiology studies were requested in 65 of the patients (35%), after the interpretation of such study.
  
  
  CONCLUSIONS
  Abnormalities in 50% were identified from the total thorax radiographies requested as the patient entered. The study application mentioned as a whole (94%) the diagnostic impression which led to the application, but only in 127 cases (34%) were supporting clinical data written down. The radiology report was attached to the file in less than half the cases (44%). In 63% of the cases the supporting reason of the study was written down whereas in 23% there was no reference to the result at all.
