Data collected from 1st January to 30th June of 2025

No intervention applied: data will only be collected in the indicated sampling periods from patients admitted to the participating hospitals.

Levels obtained in the health outcomes identified as study variables: anxiety, measured with the Golberg scale; sleep quality, measured with the Athens Sleep Scale; frailty status, measured with the Tilburg Index; level of pain, measured with the Visual Analogue Pain Scale; level of care dependency, measured with the INICIARE scale; and the variables of mortality, falls, venous catheter infection and pressure injuries, which will be asked with items created ad-hoc. We will also study the association between the results obtained with the aforementioned scales and the variables of organisational context and structure of the centre: management leadership, measured with the Leadership Scale; nurse-patient relationship, measured with the NIC_CA Scale; work stress, measured with the Nursing Stress Scale; work conditions, measured with the PES-NWI Scale; and the variables of turnover intention and nurse-patient ratio, measured with questions designed ad hoc.

Design of a predictive model based on regression models of the occurrence of adverse events (falls, mortality, venous catheter infection pressure injuries, which will be asked with items created ad-hoc) and their relationship with the rest of the study variables (assessed with the scales used for outcome 1).
