RT Journal Article T1 Concordance between the Clinical Definition of Polypathological Patient versus Automated Detection by Means of Combined Identification through ICD-9-CM Codes A1 Gómez Salgado, Juan A1 Bernabeu Wittel, Máximo A1 Aguilera González, Carmen A1 Goicoechea Salazar, Juan Antonio A1 Larrocha, Daniel A1 Nieto Martín, María Dolores A1 Moreno Gaviño, Lourdes A1 Ollero Baturone, Aníbal AB It is unknown whether the digital application of automated ICD-9-CM codes recordedin the medical history are useful for a first screening in the detection of polypathological patients.In this study, the objective was to identify the degree of intra- and inter-observer concordance inthe identification of in-patient polypathological patients between the standard clinical identificationmethod and a new automatic method, using the basic minimum data set of ICD-9-CM codes inthe digital medical history. For this, a cross-sectional multicenter study with 1518 administrativelydischarged patients from Andalusian hospitals during the period of 2013–2014 has been carriedout. For the concordance between the clinical definition of a polypathological patient and thepolypathological patient classification according to ICD-9-CM coding, a 0.661 kappa was obtained(95% confidence interval (CI); 0.622–0.701) with p < 0.0001. The intraclass correlation coe cientbetween both methods for the number of polypathological patient categories was 0.745 (95% CI;0.721–0.768; p < 0.0001). The values of sensitivity, specificity, positive-, and negative predictive valuesof the automated detection using ICD-9-CM coding were 78%, 88%, 78%, and 88%, respectively.As conclusion, the automatic identification of polypathological patients by detecting ICD-9-CM codesis useful as a screening method for in-hospital patients.
