Liver tumours are a leading cause of global morbidity and mortality. Current diagnostic tools, including computed tomography (CT), magnetic resonance imaging (MRI) and intraoperative ultrasound (IOUS), have limitations in detecting liver neoplasms. Indocyanine green (ICG) has emerged as a promising tool for improving liver tumour detection. This study aims to assess the impact of preoperative ICG on intraoperative tumour detection in minimally invasive surgery and develop a machine-learning algorithm to enhance tumour detection using ICG fluorescence.

This prospective, multicentre, phase IV clinical trial adheres to Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines. Patients with liver tumours eligible for minimally invasive surgery and a preoperative imaging test will be included. ICG will be administered intravenously 24 hours before surgery. Intraoperative procedures will include IOUS, ICG mapping and photographic documentation. Patients will be followed for 90 days to assess tumour progression, morbidity and mortality. The photographic analysis will enable the development of an artificial intelligence algorithm using machine learning and neural networks to identify lesions based on ICG fluorescence. The estimated sample size is 173 patients and the trial is predicted to accrue in 3 years.

The trial will be conducted in accordance with the Declaration of Helsinki and the Spanish Agency of Medicines and Medical Devices (AEMPS) guidelines. Approved by the local institutional Ethics Committee and the AEMPS, the results will be shared with the scientific community through publications and conferences.

Safety culture is essential to improving healthcare quality. Paediatric emergency departments are high-risk environments where evaluating safety culture helps identify areas for improvement. This study aimed to analyse the safety culture among professionals in paediatric emergency departments, according to job category and gender.

Multicentre cross-sectional study using the Hospital Survey on Patient Safety Culture (HSOPSC).

19 paediatric emergency departments, covering all levels of care.

1843 healthcare professionals were invited to participate; the response rate was 63.8%, and 33% of respondents were nurses. All clinical staff in paediatric emergency departments were eligible. Professionals from other specialties and non-clinical staff were excluded.

The primary outcome was the assessment of patient safety culture using the HSOPSC, following the methodology of the Agency for Healthcare Research and Quality. Secondary outcomes included comparisons by job category and gender, and an exploratory cluster analysis.

In terms of patient safety, the main strength was ‘teamwork within units’ (83.65% positive), while the main weakness was ‘staffing’ (61.92% negative). Patient safety was rated with an average score of 7.21 by the participants. Paediatricians rated ‘manager expectations’ significantly higher than nurses (p=0.023) and residents (p=0.026). Paediatricians gave more positive responses overall, with significant differences in ‘communication openness’, ‘feedback and communication’, ‘non-punitive response’ and ‘teamwork across units’, though none were classified as strengths. Cluster analysis showed that the group with more paediatricians identified more strengths and no weaknesses, while the group with more nurses and nursing assistants showed no strengths and significant weaknesses in ‘overall safety perception’, ‘staffing’ and ‘management support’.

Safety culture in paediatric emergency departments is acceptable, but still far from excellent, indicating ample room for improvement. Differences between professional categories, especially between paediatricians and nurses, highlight the need for targeted safety strategies and leadership involvement.
