OBJECTIVE: To assess the performance of paramedics, in a newly-initiated prehospital program, during invasive airway management. METHODS: An audit of paramedic call reports for a 12-month period from January to December 1997 was performed. Call reports that documented invasive airway management were retrieved and relevant data were extracted using a preformulated data-entry form. RESULTS: Paramedics attempted tracheal intubation in 453 patients and were successful in 408 (90.1%); 331 of the patients were in cardiopulmonary arrest with vital signs absent (VSA), 101 had medical emergencies, and 21 had trauma-related problems. In the VSA cohort, the tracheas of 96% of the patients were intubated successfully; 80.1% on the first attempt, 10.6% on the second, 4.5% on the third, and 0.9% after more than three attempts. In the medical cohort, the tracheas of 74.3% of the patients were intubated; 60.4% on the first attempt, 11.9% on the second, and 2.9% on the third. In the trauma cohort, 71.4% of the intubations were successful; 66.6% on the first attempt, 26.6% on the second, and 6.6% on the third. There was a difference (p < 0.001) in the incidence of successful intubations comparing the VSA cohort with the medical/trauma cohorts. There was also a difference (p < 0.001) between the success rate for nasal intubations (43 of 68, 63% of patients successfully intubated) and that for oral intubation (365 of 385, 94% of patients). CONCLUSION: This study demonstrated a difference in the paramedics' success rates for tracheal intubation in VSA patients compared with those with preserved airway reflexes and a lower success rate for nasal vs oral tracheal intubation. These differences may be due to inadequate training, technical difficulties experienced in the field, or lack of sufficient exposure to medical/trauma scenarios to gain management experience. Future training to address these issues, both in the initial training phase and in the continuing education program, may be beneficial in improving performance.
