Correction to “Prospective comparison of three methods for detecting peri-operative neurocognitive disorders in older adults undergoing cardiac and non-cardiac surgery”

van Zuylen ML, Kampman JM, Turgman O, et al. Prospective comparison of three methods for detecting peri-operative neurocognitive disorders in older adults undergoing cardiac and non-cardiac surgery. Anaesthesia 2023; 78: 577–586. https://doi.org/10.1111/anae.15965.

In the article cited above, it has come to our attention that an inadvertent data processing error occurred during the merging of our datasets. Specifically, the column containing preoperative BNT-30 test scores was erroneously duplicated into the postoperative speed and attention cognitive domain column. Consequently, several erroneous outcomes were reported, including an inflated number of patients diagnosed with peri-operative neurocognitive disorders (PNCD).

After discovering this error, we repeated all statistical analyses with the correct data, taking utmost care to rectify the erroneous data. Despite the revised findings indicating a lower incidence of PNCD, all conclusions drawn in the original manuscript remain unchanged. The lower PNCD incidence remains appropriate for the population studied.

Revised supplementary materials have been posted to the original article; text corrections are outlined below. Corrected versions of Table 2 and Figure 3 appear following the text corrections.

Page 577, Summary:

“Postoperative Modified Telephone Interview for Cognitive Status and cognitive domain scores were very weakly to weakly correlated (r = 0.09–0.36).”

should be changed to “Postoperative Modified Telephone Interview for Cognitive Status and cognitive domain scores were very weakly to weakly correlated (r = 0.10–0.36).”

Page 580, Results:

“Postoperative Modified Telephone Interview for Cognitive Status scores showed very weak to weak correlations with postoperative scores on the complete neuropsychological assessment (r = 0.09–0.36).”

should be changed to “Postoperative Modified Telephone Interview for Cognitive Status scores showed very weak to weak correlations with postoperative scores on the complete neuropsychological assessment (r = 0.10–0.36).”

Page 582:

“showed moderate to good test–retest reliability, except for the ‘speed and attention’ cognitive domain (see online Supporting Information Appendix S10).”

should be changed to “showed moderate to good test–retest reliability (see online Supporting Information Appendix S10).”

“Of the included patients, 21 (27%) had postoperative neurocognitive disorders”.

should be changed to “Of the included patients, 14 (18%) had postoperative neurocognitive disorders”.

Page 583:

“The exceptions to this were pre-operative Montreal Cognitive Assessment scores, which were higher in the postoperative neurocognitive disorder group (p = 0.032) and the ‘memory’ cognitive domain, which was higher in the postoperative neurocognitive disorders group (p = 0.006).”

Should be changed to “The exceptions to this were the postoperative ‘memory’ cognitive domain scores, which were lower in the postoperative neurocognitive disorders group (p = 0.001).”

“compared with those identified by Modified Telephone Interview for Cognitive Status (p = 0.193) and Montreal Cognitive Assessment (p = 0.320).”

Should be changed to “compared with those identified by Modified Telephone Interview for Cognitive Status (p = 0.920) and Montreal Cognitive Assessment (p = 0.616).”

“The sensitivity and specificity of postoperative neurocognitive disorders identified by Modified Telephone Interview for Cognitive Status compared with neuropsychological assessment was 0.14 (95%CI 0.04–0.37) and 0.95 (95%CI 0.84–0.99), respectively.”

Should be changed to “The sensitivity and specificity of postoperative neurocognitive disorders identified by Modified Telephone Interview for Cognitive Status compared with neuropsychological assessment was 0.07 (95%CI 0.04–0.28) and 0.92 (95%CI 0.84–0.97), respectively.”

“the Modified Telephone Interview for Cognitive Status was 0.61 (95%CI 0.37–0.85) and for the Montreal Cognitive Assessment was 0.60 (95%CI 0.41–0.79).”

should be changed to “the Modified Telephone Interview for Cognitive Status was 0.50 (95%CI 0.33–0.66) and for the Montreal Cognitive Assessment was 0.53 (95%CI 0.36–0.70).”

We apologise for these errors.
