Rating delirium severity in the presence of co-occurring dementia is challenging due to overlapping features of delirium and ADRD. The multi-site prospective Better ASsessment of ILlness (BASIL)-II study will develop and validate a new delirium severity instrument for use in patients with and without ADRD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>Describe an expert panel process used to rate delirium severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Clinical assessors conducted standardized cognitive tests. A separate panel of experts independently reviewed assessors\u2019 reports, rated delirium severity using a 0\u201310 scale, and assigned dementia diagnoses using DSM-5 criteria. Panel agreement was defined using\n                      <jats:italic toggle=\"yes\">a priori<\/jats:italic>\n                      criteria.

After initial review, 80% of cases were in agreement for delirium severity. Kappa was 0.86 (95% CI, 0.78, 0.82) before expert panel discussion and 0.90 (95%CI, 0.89, 0.92) after consensus. Final delirium severity ratings were no delirium (48%); subsyndromal (22%), mild-moderate (25%), or severe (6%). Disagreement in delirium severity was associated with ADRD (OR 3.02), nursing home setting (2.63), and vision impairment (2.42).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This rigorous process provides confidence that delirium severity can be rated accurately in patients with and without ADRD.
