Clinical information was used to calculate the Pneumonia Prognostic Index (PPI).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>RESULTS:<\/jats:bold>\n                    Eighty\u2010four (75%) patients were functionally independent (FI) before admission, with a SMAF score of 40 or lower. Dementia and aspiration history were higher in the group that was functionally dependent (FD) before admission (\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.001). The FI group had less\u2010severe pneumonia per the PPI and shorter mean LOS\u00b1standard deviation (5.62\u00b10.51 days) than the FD group (11.42\u00b12.58,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.004). The FI group had lower 1\u2010year mortality (19\/65, 23%) than the FD group (14\/28, 50%), and the difference remained significant after adjusting for Charlson Index and severity of illness (\n                    <jats:italic>P<\/jats:italic>\n                    =.009). All patients lost function after admission, with loss being more pronounced in the FI group (mean change 19.24\u00b112.9 vs 4.72\u00b16.55,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.001).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>CONCLUSION:<\/jats:bold>\n                    Older adults who were FI before admission were more likely to present with less\u2010severe pneumonia and have a shorter LOS. In addition, further loss of function was common in these patients. Assessment of function before and during hospitalization should be an integral part of clinical evaluation in all older adults with pneumonia.\n                  <\/jats:p>","DOI":"10.1111\/j.1532-5415.2006.00797.x","type":"journal-article","created":{"date-parts":[[2006,6,7]],"date-time":"2006-06-07T15:50:44Z","timestamp":1149695444000},"page":"1062-1067","source":"Crossref","is-referenced-by-count":56,"title":["Assessment of Pneumonia in Older Adults: Effect of Functional Status"],"prefix":"10.1111","volume":"54","author":[{"given":"Lona","family":"Mody","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongjun","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suzanne F.","family":"Bradley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,7,6]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"144","article-title":"National Hospital Discharge Survey","volume":"13","author":"Kozak LJ","year":"1999","journal-title":"Annual summary, 1997"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-118-3-199302010-00011"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02598279"},{"key":"e_1_2_6_5_2","first-page":"298","article-title":"Mortality from lower respiratory infection in nursing home residents.
