| dc.description.abstract | Introducción: En Colombia aumenta progresivamente la tasa de mortalidad de los pacientes con enfermedad renal crónica avanzada en terapia de reemplazo renal y aumenta las tasas de hospitalización, motivo por el cual se desarrollan y validan unos modelos pronósticos de mortalidad a tres años y de hospitalización a un año. Métodos: Búsqueda de literatura sobre factores pronósticos; selección de variables por panel de expertos con metodología Delphi modificada; cohortes retrospectivas de pacientes con enfermedad renal crónica avanzada del año 2014 para la creación de modelos pronósticos de mortalidad y hospitalización. Validación interna mediante bootstrapping y validación externa con cohortes retrospectivas de pacientes de los años 2015-2017; evaluación de discriminación (índice-C Harrell), calibración (gráficas de calibración), rendimiento diagnóstico (curva ROC) y utilidad clínica (análisis de decisiones); metodología según el marco de referencia PROGRESS. Resultados: Modelo de mortalidad a tres años: 2.343 pacientes, 983 (41,95%) mujeres, edad 61,6 años (IQR= 21,6); índice-C: 0,9404; Calibración: p=0,649; AUC-ROC: 0,7454 [IC95% 0,7199–0,7709]; beneficio neto con umbral de probabilidad: 12%. Validación interna: índice-C: 0,9447; Calibración: p=0,542; AUC-ROC: 0,7382 [IC95% 0,7117-0,7647]; beneficio neto con umbral de probabilidad: 11%. Validación externa: 3.688 pacientes, 560 (42,30%) mujeres, edad 61,5 años (IQR= 20,9); índice-C: 0,9463; Calibración: p=0,184; AUC-ROC: 0,7423 [IC95%: 0,7228–0,7619]; beneficio neto con umbral de probabilidad: 13,5%. Modelo de hospitalización a un año: 2.819 pacientes, edad 62,1 años (IQR: 21,6), 42,36% mujeres; índice-C: 0,8962; Calibración: p=0,948; AUC-ROC: 0,5958 [IC95% 0,5711–0,6204]; beneficio neto con umbral de probabilidad: 25%. Validación interna: índice-C: 0,8959; Calibración: p=0,776; AUC-ROC: 0,6060 [IC95% 0,5825–0,6313]; beneficio neto con umbral de probabilidad: 24%. Validación externa: 4.054 pacientes, edad 61,0 años (IQR: 20,6), 43,62 % mujeres; índice-C: 0,9089; Calibración: p=0,135; AUC-ROC: 0,6155 [IC95%: 0,5985–0,6325]; beneficio neto con umbral de probabilidad: 25%. Conclusión: Se obtiene un modelo de mortalidad con rendimiento diagnóstico moderado y un modelo de hospitalización con rendimiento diagnóstico leve, ambos elaborados y validados y muestras colombianas.

| dc.description.abstract | Introduction: In Colombia, death and hospitalization rates of patients with advanced chronic kidney disease undergoing renal replacement therapy are progressively increasing. Consequently, three-year mortality and one-year hospitalization prognostic models were developed and validated Methods: Literature search for prognostic factors, variable selection through a modified Delphi expert panel, retrospective cohorts of patients with advanced chronic kidney disease from 2014 for development of mortality and hospitalization prognostic models. Internal validation was performed using bootstrapping, external validation with retrospective patient cohorts from 2015-2017. Evaluation included discrimination (Harrell's C-index), calibration (calibration plots), diagnostic performance (ROC curve), and clinical utility (decision analysis). Based on the PROGRESS framework Results: Three-year mortality model: 2.343 patients, 983 (41,95%) women, median age 61,6 years (IQR= 21,6); C-index: 0,9404; Calibration: p=0,649; AUC-ROC: 0,7454 [95% CI 0,7199–0,7709]; net benefit with probability threshold: 12%. Internal validation: C-index: 0,9447; Calibration: p=0,542; AUC-ROC: 0,7382 [95% CI 0,7117-0,7647]; net benefit with probability threshold: 11%. External validation: 3.688 patients, 560 (42,30%) women, median age 61,5 years (IQR= 20,9); C-index: 0,9463; Calibration: p=0,184; AUC-ROC: 0,7423 [95% CI: 0,7228–0,7619]; net benefit with probability threshold: 13,5%. One-year hospitalization model: 2.819 patients, median age 62,1 years (IQR: 21,6), 42,36% women; C-index: 0,8962; Calibration: p=0,948; AUC-ROC: 0,5958 [95% CI 0,5711–0,6204]; net benefit with probability threshold: 25%. Internal validation: C-index: 0,8959; Calibration: p=0,776; AUC-ROC: 0,6060 [95% CI 0,5825–0,6313]; net benefit with probability threshold: 24%. External validation: 4.054 patients, mean age 61,0 years (IQR: 20,6), 43,62% women; C-index: 0,9089; Calibration: p=0,135; AUC-ROC: 0,6155 [95% CI: 0,5985–0,6325]; net benefit with probability threshold: 25% Conclusion: A mortality prognostic model with moderate diagnostic performance and a hospitalization prognostic model with mild diagnostic performance were obtained, both developed and validated in the Colombian samples. | eng |
