In this study, the objective was to identify the degree of intra- and inter-observer concordance in the identification of in-patient polypathological patients between the standard clinical identification method and a new automatic method, using the basic minimum data set of ICD-9-CM codes in the digital medical history. For this, a cross-sectional multicenter study with 1518 administratively discharged patients from Andalusian hospitals during the period of 2013-2014 has been carried out. For the concordance between the clinical definition of a polypathological patient and the polypathological patient classification according to ICD-9-CM coding, a 0.661 kappa was obtained (95% confidence interval (CI); 0.622-0.701) with penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/ICD-9-CMcost effectivenessmultimorbiditymultiple chronic conditionspatient safetypolypathological patientpopulation health managementresearch article31064157open access10.3390/jcm8050613PMC6572229https://www.mdpi.com/2077-0383/8/5/613/pdf?version=1557154983https://pmc.ncbi.nlm.nih.gov/articles/PMC6572229/pdf
