Hospitals face challenges in maintaining these metrics due to operational constraints and unexpected emergent cases. Our goal was to compare TOT, FST, and total admission time for elective cases performed in angiography suites at an ambulatory neurosurgery center (ANSC) versus a tertiary hospital (TH).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>We conducted a retrospective analysis of data for patients who underwent elective diagnostic or interventional neuroendovascular procedures at the TH or ANSC from January 2024 through October 2024. TOT was defined as the time between the end of one case and the start of the next. FST was defined as the time the first patient of the day entered the suite. In addition, digital subtraction angiography cases at the ANSC were age- and indication-matched with same-day discharge digital subtraction angiography cases from the TH to compare total admission, preprocedural wait, procedural, and postprocedural times (minutes).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      A total of 1174 procedures were performed at the TH and 155 at the ANSC. Mean TOT was longer at the TH (30.6\u2009\u00b1\u200925 minutes) than the ANSC (12\u2009\u00b1\u20092.8 minutes;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.0001).
