Procedure types The breakdown of procedure by type during 2021 is shown in Figure 4A and by month in Figure 4B. Combined, DSA and emergency NI represented the majority (75.6%) of the procedure types performed by the unit over this period. Figure 4B shows that there was a high proportion of emergency neurointerventional procedures for May; contributing to the unusually high number of total procedures for this month. It should be noted that the ‘other/non-neuro’ procedure type category includes sclerothrapy, vertebroplasty, lumber puncture, non-neuro angiograms (renal, spinal), nerve block including sphenopalatine ganglion block, and non-neuro embolisation procedures.
Neurointerventional Procedures
Total number of procedures A total of 852 NI procedures were performed by the RNSH NI consultants in 2021, this number includes both diagnostic and treatment procedures.
Figure 3 shows the total number of procedures in 2021 compared to 2020 (n=863) across each month.
In 2020, there was a substantial decrease in procedures in April to May (attributed to the impact of COVID-19 on procedural activity) and a significant increase in numbers for July, August and December when compared to the other months over this period and the same period for 2019.
From 2020 to 2021, the total procedural workload decreased by 1.3%.
