Evaluation of SINERGIAPS, an intervention to improve patient safety in primary healthcare centers in Spain based on patients' perceptions and experiences: a protocol for a hybrid type I randomized clinical trial.

Background: Adverse events in the primary care setting result in a direct cost equivalent to at least 2.5% of total healthcare spending. Across OECD countries, they lead to more than seven million avoidable hospital admissions annually.

Relationship between adverse events prevalence, patient safety culture and patient safety perception in a single sample of patients: a cross-sectional and correlational study.

Objective: To assess the relationship between adverse events prevalence (AEP), patient safety culture (PSC) and patient safety perception (PSP).

Design: Cross-sectional, ex post facto comparative study on a single sample of patients.

Setting: Four medium-high-level hospitals were included in the study-two public and two private from Zulia State in Venezuela.
