PEM was assessed using serum albumin and total lymphocyte count (TLC). Studied outcome parameters were length of pre-operative and post-operative stay, complications up to six months after surgery and 12-month mortality.

Length of pre-operative stay differed significantly (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.001) between PEM (median 7, range 1\u201336\u00a0days) and non PEM (median 1, range 1\u201322\u00a0days). In the PEM group, 12 (44.4%) patients had post-operative complications within six months after OP and 15 (7.8%) patients in the non PEM group (HR\u2009=\u20096.3, 95% CI 1.7\u201323.1).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>We observed a higher post-operative complication rate for malnourished patients undergoing elective THA.
