CO12 Development of Frailty Index Using ICD-10 Codes to Predict Mortality and Rehospitalization of Older Adults: An Update of the Multimorbidity Frailty Index

Several frailty indices have been constructed to identify frail older people at increased risk of mortality and admission. Previously, we have developed a claims-based multimorbidity frailty index (mFI) using Taiwan’s National Health Insurance Research Database (NHIRD). As the ICD-10 coding system was adopted to replace the previous ICD-9-CM system in Taiwan in 2016, it is necessary to renew the mFI using ICD-10 codes and assess the types of deficits and their association with clinical outcomes.
