Hypothesis
This study aimed to analyse the utilisation of head CT scans for patients with minor head trauma in two major hospitals in Lithuania and Poland.
Conclusion
A significant number of head CT scans performed were not necessary according to existing head CT guidelines and risk calculators.
Supporting Evidence
- 611 patients were included in the study.
- 92% of patients with minimal trauma were younger than 65 years old.
- 83% of non-emergency medicine physicians ordered head CT scans compared to 62% of emergency medicine physicians.
- Only 8 (1%) of the CT scans were categorised as clinically significant.
- Patients over 65 were more likely to undergo a head CT scan.
Takeaway
Doctors are doing too many CT scans for people with minor head injuries, even though most of them don't need it.
Methodology
A retrospective, descriptive study of CT utilisation in minor head trauma patients presenting to two emergency departments.
Potential Biases
Defensive medicine may lead to unnecessary CT scans due to fear of medical error.
Limitations
The study was conducted in two hospitals for only 3 months, which may not represent the entire patient population.
Participant Demographics
Most patients were younger than 65 years old, with a significant portion being older adults who suffered falls.
