Dementia status was determined using validated cognitive assessments (Hurd method); hip fracture and pneumonia were identified from Medicare claims. Outcomes were 1\u2010year mortality and function, defined as a summary score of requiring assistance with 6 ADL's and 5 IADL's, with higher scores indicating better function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among people with dementia, predicted 1\u2010year mortality was higher among those with hip fracture (35.4%) versus those without hip fracture (14.8%), with similar patterns for pneumonia (49.6% vs. 13.0%). Among people with dementia, function declined abruptly at time of hip fracture (\u22122.09 [95% CI \u22122.94, \u22121.25]) and continued to decline after (\u22120.48 [95% CI \u22120.87, \u22120.09]). There were similar patterns for pneumonia (drop at time of pneumonia of \u22121.49 [95% CI \u22122.0, \u22120.97] and after \u22120.05 [95% CI, \u22120.29, 0.19]). Compared to people without dementia with hip fracture, people with dementia had higher 1\u2010year mortality (35.4%) versus people without dementia (24%), with similar patterns for pneumonia (49.6% vs. 39.7%). Function stabilized for people without dementia after hip fracture (\u22120.03, 95% CI \u22120.22, 0.16), which was significantly different than people without dementia (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001).
