Variation in coded frailty syndromes in secondary care administrative data: an international retrospective exploratory study.

ABSTRACT:

Objectives

Challenges with manual methodologies to identify frailty, have led to enthusiasm for utilising large-scale administrative data, particularly standardised diagnostic codes. However, concerns have been raised regarding coding reliability and variability. We aimed to quantify variation in coding frailty syndromes within standardised diagnostic code fields of an international dataset.

Setting

Pooled data from 37 hospitals in 10 countries from 2010 to 2014.

Participants

Patients ≥75 years with admission of >24 hours (N=1 404 671 patient episodes).

Primary and secondary outcome measures

Frailty syndrome groups were coded in all standardised diagnostic fields by creation of a binary flag if the relevant diagnosis was present in the 12 months leading to inde
