Patients with preoperative cognitive dysfunction and dementia were excluded. The incidence of POD was compared between the CT and routine care (RC) groups as the primary outcome.

The overall incidence of POD was 8.2% (10 out of 122), with no significant difference between the two groups (9.8% for CT group vs. 6.6% for RC group; P\u00a0=\u2009.509). Secondary outcomes also showed no significant difference between the two groups. The training time was less, and the compliance rate was poor in the CT group (4.0%). Nonetheless, the results revealed a significant difference in POD rates among CT subgroups, and a robust correlation was identified between CT sessions lasting less than the median duration of 12\u00a0minutes and the incidence of POD (P\u00a0=\u2009.043).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The incidence of POD in older patients undergoing total hip or knee arthroplasty may not be mitigated by CT.
