[en] Background:(1) The model attributes were classified as: pain assessment, interventions and reassessment. Background:(2) Greater importance is given to pain assessment and pharmacological interventions. Background:(3) There was greater variability in the pain care measures prescribed by nurses. Background:(4) Absence of multidimensional instruments for pain assessment was identified. Background:(5) Pain care interventions were prescribed recurrently in aged people at risk of falls. to develop an information model on pain management in hospitalized aged people. a Big Data retrospective and observational study guided by the Applied Healthcare Data Science Roadmap. The sample included all Electronic Health Records related to pain management in older adults aged at least 75 years old considered vulnerable in the institution and admitted to clinical and surgical units. Data science packages were used in Python ® for data analysis. a total of 9,635 hospitalizations were found for 4,753 patients, with a mean age of 81 years old and 54% belonging to the female gender. The main reasons for hospitalization were diseases of the circulatory system (n=1,593; 28.6%), neoplasms (n=893; 16%) and diseases of the genitourinary system (n=508; 9.1%). A total of 60 attributes related to pain were identified and organized into groups: current pain, assessment instruments and characteristics, Nursing diagnosis, etiology of the Nursing diagnosis, interventions for relief, consultations to specialties and pain reassessment. The groups were classified into four large panels that constituted the information model. the information model developed presented an overview of the healthcare reality of pain management in vulnerable aged people, supporting decision-making for pain management in this population segment.

Se identificaron 60 atributos relacionados con el dolor, organizados en los siguientes grupos: dolor actual, instrumentos y características de evaluación, diagnóstico de enfermería, etiología del diagnóstico de enfermería, intervenciones para el alivio, consultoría de especialidades y reevaluación del dolor. Los grupos se clasificaron en cuatro grandes paneles que conformaron el modelo de información. el modelo de información desarrollado presentó una visión general de la realidad asistencial del manejo del dolor en adultos mayores vulnerables, que contribuye a la toma de decisiones para el manejo del dolor en esta población.
