  • carries a procedural risk, and/or
  • carries an anaesthetic risk, and/or
  • requires specialised training, and/or
  • requires special facilities or equipment only available in an acute care setting.

Number of procedures

Among the 23,445 patients in the cohort, there were almost 66,800 procedures administered (an average of 2.8 procedures each) during patients' initial TBI hospitalisations. However, half the patients in the cohort (11,700; 50%) did not receive any procedures (for example, where the patient only required observation). Among the 11,750 (50%) who received at least one procedure, the average number of procedures was 5.7 per patient.

The average number of procedures per patient varied by TBI diagnosis (Figure 13; Table S7). Among patients with a TBI as a principal diagnosis, patients with a concussive TBI received many fewer procedures than patients with other types of TBIs as a principal diagnosis. The same pattern occurred among patients with an additional diagnosis TBI, but those patients received more procedures on average than patients with a principal diagnosis TBI. Note, that it is not possible to say whether or to what extent procedures were for treatment of the TBI or, in the case of patients who had other non-TBI diagnoses, for other conditions.

This column graph shows that patients in the cohort with an additional diagnosis of non-concussive TBI received, on average, the most procedures during their initial hospitalisation (8.7 procedures each). The diagnosis groups with the next highest average number of procedures were those with a principal diagnosis of traumatic subdural haemorrhage (6.7), traumatic subarachnoid haemorrhage (6.3), and other TBI (5.8). Those with a principal diagnosis of concussion had the fewest average number of procedures (0.5).

Types of procedure

Half (51%; 34,250) of procedures performed during initial TBI admissions were allied health interventions and 11.5% were for general anaesthesia or sedation (Figure 14; Table S8).

This column graph shows that allied health interventions were the most common type of procedure patients in the cohort received during initial TBI hospitalisations. (34,251). 7,704 general anaesthesia/sedation procedures, 2,161 ventilatory support procedures, and 2,093 blood products were administered.

Among the 34,250 allied health interventions provided, physiotherapy was the most common procedure (14% of procedures; 9,100), followed by occupational therapy (12%; 8,200) and social work (8.3%; 5,600) (Figure 15; Table S7).

This column graph shows that among allied health interventions, physiotherapy (9,125), occupational therapy (8,171), social work (5,570), pharmacy (3,572), dietetics (2,608), speech pathology (2,345) and prosthetics/orthotics (1,113) were the most common.
