We appreciate Kumar et al. for their thoughtful observation and comments[1] on our published study.[2]
The conclusion in the abstract meant to emphasise that the hypothesis was proved right, and the hypothesis was that frailty would be associated with postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). The higher odds ratio (OR) of frailty with POD (OR: 2.93) and POCD (OR: 5.38) displays the strength of this association, as rightly identified by Kumar et al. However, in no possible way was causation implicated. Similarly, Fu et al.[3] demonstrated a pooled adjusted OR of 3.23 for delirium in frail patients.
This was discussed in detail in the current study, and, in fact, it concluded that frailty could predict POD and POCD in elderly patients undergoing non-cardiac surgery; therefore, routine frailty assessment should be considered in such patients.
