Background and purpose. During the first wave of the epidemic caused by SARS-CoV-2, hospitals have come under significant pressure. This scenario of uncertainty, low scientific evidence, and insufficient resources, has generated significant variability in practice between different health organisations. In this context, it is proposed to develop a standards-based model for the evaluation of the preparedness and response system against COVID-19 in a tertiary hospital. Materials and methods. The study, carried out at the University Hospital of Vall d'Hebron in Barcelona (Spain), was designed in two phases: 1) development of the standards-based model, by means of a narrative review of the literature, analysis of plans and protocols implemented in the hospital, a review process by expert professionals from the centre, and plan of action, and 2) validation of usability and usefulness of the model through self-assessment and hospital audit. Results. The model contains 208 standards distributed into 9 criteria: leadership and strategy; prevention and infection control; management of professionals and skills; public areas; healthcare areas; areas of support for diagnosis and treatment; logistics, technology and works; communication and patient care; and information and research systems. The evaluation achieved 85.2% compliance, with 42 areas for improvement and 96 good practices identified. Conclusions. Implementing a standards-based model is a useful tool to identify areas for improvement and good practices in COVID-19 preparedness and response plans in a hospital. In the current context, it is recommended to repeat this methodology in other non-hospital and public health settings.
