Background: Observation and repeated examination may lead to favourable clinical outcomes in the ever-challenging diagnosis of appendicitis. The goal of this study was to evaluate clinical performance in the diagnosis of suspected appendicitis in a centre with limited access to medical imaging technologies and to identify factors associated with complicated cases.Methods: A retrospective review of the medical records of 211 consecutive surgical cases of suspected appendicitis, spanning an 11-year period, was performed. The delays before treatment and the subsequent patient outcomes were evaluated.Results: There were 8.1% of cases with negative findings on appendectomy, 75.8% with uncomplicated appendicitis, 12.3% with complicated appendicitis and 3.8% with other surgical conditions. The delay before the first medical consultation was significantly longer in patients with complicated appendicitis. The various delays after the first medical consultation did not differ significantly between the groups.Conclusions: In the context of limited available medical imaging modalities, clinical observation was not associated with an increased incidence of complicated appendicitis. The presence of complicated appendicitis was associated with the delay before the patient's first medical consultation. Clinical judgment can be prioritized and can lead to good clinical performance in the management of patients with suspected appendicitis, with no significant increase in rates of complicated appendicitis and negative findings on appendectomy.

BACKGROUND: Length of hospitalization is a good indicator of resource utilization. Older patients are increasingly suffering trauma, and comorbid medical conditions are also increasing. Our objective was to determine the separate and combined effect of these 2 factors on length of hospital stay for trauma patients in a tertiary trauma centre. METHODS: All 994 consecutive trauma patients surviving to hospital discharge between Apr. 1, 2000, and Mar. 31, 2001, were identified. Patient characteristics, injury severity and length of hospitalization were obtained from the hospital trauma registry. Each medical record was then reviewed for completeness of information and assessment of comorbid conditions. A multivariate linear regression model was developed to predict logarithmic length of stay from age and presence of a cormorbid condition while adjusting for the Injury Severity Score (ISS). RESULTS: The mean age of the patients was 49.7 (range from 14-100) years and median ISS was 9 (range from 1-50). At least 1 comorbid condition was present in 321 (32%) patients. Mean length of hospital stay was 15.3 days. The proportion of patients with a comorbid condition increased steadily with age, from 8.7% before the age of 55 years to 92% at 85 or more years of age (p < 0.001). According to the multivariate model, the presence of comorbidity, age and ISS were all independent predictors of hospital stay (p < 0.001). When applied to patients with the mean ISS value of 9, the model showed an increase in length of hospitalization for patients with a comorbid condition over those without; (3.6 v. 13.1 d for patients < 55 and > or = 85 yr respectively). Length of hospital stay increased particularly with neurologic and pulmonary problems. CONCLUSIONS: Comorbidity and age were both independently significant predictors of length of hospitalization over and beyond that which is expected based on the severity of the injuries. With an aging population, this phenomenon should severely affect resource utilization in trauma centres in the near future. Researchers should take account of both age and comorbidity in order to compare trauma populations. [ABSTRACT FROM AUTHOR]

BACKGROUND: The frequency of penetrating trauma is low in Canada. Current recommendations for the care of patients with penetrating injuries originate from inner city trauma centres with a high volume of such injuries and may not apply to Canada. The purpose of this study was to review the incidence and treatment of penetrating thoracoabdominal injuries in the 4 tertiary trauma centres in Quebec. METHODS: We identified all patients with penetrating thoracic or abdominal injuries who were taken to any of the 4 tertiary trauma centres in the province of Quebec between Apr. 1, 1998, and Mar. 31, 2001. Patients who were dead on arrival were excluded. Only patients with an Abbreviated Injury Scale of 2 or greater for the thoracic or abdominal regions were included. RESULTS: In total, 245 patients meeting our inclusion criteria were identified. Of these 223 (91%) were male. The mean (and standard deviation) age was 33.8 (13.2) years; range 15-90 years. The median Injury Severity Score was 10 (range 4-75). Overall in-hospital mortality was 6.9%. There were 203 patients (82.8%) with thoracic injuries and 192 patients (78.4%) with abdominal injuries. Fifty (20.4%) of these patients had injuries to both regions. A thoracotomy was carried out in 48 (31.4%) of 153 patients who had injuries to the thorax, and the abdomen was explored in 133 (93.7%) of the 142 patients with abdominal injuries. The incidence of these injuries in the study period varied from 3 to 49 cases per centre. CONCLUSIONS: The annual incidence of penetrating thoracoabdominal injuries is extremely low in all 4 of Quebec's tertiary trauma centres, and the number of thoracoabdominal procedures is even lower. Such a low exposure may jeopardize education and clinical competence. We need to rethink our educational strategies both for residents and for continuing medical education. New approaches to training and maintenance of competence must be developed. [ABSTRACT FROM AUTHOR]
