The area under the curve of the score for the prediction of prolonged hospital stay is 0.960, and a cutoff point \u2265 3 predicts prolonged stay with a sensitivity of 84.5% and a specificity of 92.5% (95% CI 0.917\u20130.984). The AECOPD-F score was validated in a second group of 88 subjects admitted to the hospital for a COPD exacerbation. In the validation group, subjects with a score \u2265 3 required prolonged stay compared with those with a score &lt; 3 (8.0 [6.0\u201310.0] vs 6.5 [4.0\u20139.0] d, respectively,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .007).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>The AECOPD-F score could accurately predict stay in hospitalized COPD subjects.
