Nursing Model and Health Outcomes of Elderly People with Multimorbidity: a Quasi-experimental Study

The goal of this quasi-experimental study is to analyze the effect of organizing nursing care according to the primary nursing model on therapeutic self-care and satisfaction with nursing care for elderly people with multimorbidity in hospital. Participants were patients of both sexes aged over 65 years with at least two chronic diseases admitted to an acute hospital ward. The main questions it aims to answer are: * Does the use of the primary nursing model increase participants' perceived ability for therapeutic self-care? * Does the use of the primary care model increase participants' satisfaction with nursing care? The researchers are comparing whether implementing the primary nursing model with the usual care model increases patients' capacity for therapeutic self-care. Participants: * Complete a self-care skills questionnaire on admission to the inpatient unit; * Complete the same self-care questionnaire on discharge from hospital; * Complete the same self-care questionnaire by telephone one month after discharge from hospital * Complete a nursing care satisfaction questionnaire on discharge from hospital;
