Brief Summary
BACKGROUND: Each year, over 13,000 patients in Catalonia and more than 4 million worldwide experience last-minute surgery cancellations (LMC) due to preoperative inefficiencies. As anaesthesia services struggle to meet surgical demands, thorough preoperative evaluations become challenging. Current resource-intensive pre-anaesthetic assessments are undermined by high demand, causing inefficiency. However, proper assessment identifies that most patients (\>70%) are low-risk and ensures high-risk patients are adequately prepared by analyzing risk profiles, health status, medical history, treatment, and lab results. RATIONALE: Previous attempts to improve preoperative risk assessment have mainly relied on self-administered questionnaires to detect at-risk patients. The investigators have identified a care model that enhances quality by adding value to preoperative risk assessment. By combining anaesthesiology expertise with AI techniques, the investigators developed an automated digital environment to detect risks, optimize visits, avoid cancellations, and reduce postoperative complications. This system uses parameterized medical knowledge to verify responses and objectively assess patient risk by integrating multiple data sources. The investigators have developed a Class IIa active diagnostic and monitoring product, a Medical Device Software (MDSW, EMDN V92), to support clinical decision-making in an automated digital preoperative environment. It helps assess patients and flags low-risk from medium/high-risk individuals, reporting personalized needs to the medical team. The software was developed exclusively by independent researchers from Bellvitge University Hospital and the Bellvitge Biomedical Research Institute (IDIBELL). HYPOTHESIS: The tool has been tested successfully on fictitious patients in controlled preclinical scenarios. The aim now is a proof-of-concept study to verify its performance with real patients in uncontrolled, real-world settings. This is a Clinical Performance Research Study, aligned with MDSW Clinical Evaluation Guidelines (MDR, MDCG 2020-1) for (EU) 2017/745, and authorized by the Spanish Agency of Medicines and Medical Devices (AEMPS) and the local Ethics Committee. MAIN OBJECTIVE: The clinical trial aims to verify that the software (aiinane), supporting preanesthetic assessment and preoperative risk estimation, is fit for its intended purpose and performs as expected under normal conditions of use. This is an observational, non-interventional, single-center, prospective, longitudinal adult cohort study. The target population is any adult (\>18 years) of any gender undergoing breast cancer surgery.

Outcome Measures
Primary Outcomes (1)
The aiinane tool is able to create a final report/document with the clinical information required for preoperative assessment
The present clinical trial aims to verify that the software (hereinafter aiinane) for the support of pre-anesthetic assessment in the estimation of preoperative risk, is adequate for its established purposes and offers the expected performance under normal conditions of use. Therefore the outcome measure is the total number of complete anesthesia reports generated.
From enrollment to 2 weeks after surgery has been performed.
Secondary Outcomes (4)
Patient Satisfaction
From enrollment to 2 weeks after surgery
Clinical usefulness

Study Arms (1)
Breast cancer surgery
Adult patients diagnosed with breast cancer that require surgery as part of their treatment plan and have planed surgery in the following weeks.
Eligibility Criteria
Target population: patients who will undergo preanesthetic evaluation at Bellvitge University Hospital for breast cancer surgery. An internal analysis performed on all types of surgical procedures in 2019 (2020 to 2022 skewed due to the COVID-19 pandemic) identified 4 types of surgery with 80% of patients categorized preoperatively as ASA I-II (low risk). From those, breast cancer surgery was the only one with a short intervention period between diagnosis, surgical indication and surgery. Patients who will undergo breast cancer surgery go through multiple visits, tests and treatments between diagnosis and surgery. Sparing them visits generates a high impact on their emotional state.
You may qualify if:
- Adult patients (age ≥18 years) of both sexes. Although breast neoplasia is a pathology with high prevalence in the female biological gender, we do not rule out recruiting patients of male biological gender.
- Who have been indicated for breast surgery to resolve breast cancer pathology.
- Subjects must understand the nature of the study procedures and provide written informed consent prior to any study-related procedures.
You may not qualify if:
- Surgery scheduled for \<7 days from enrollment
- Inability to participate in the study, in the opinion of the investigator, due to, for example, severe brain damage, language barrier, dementia, or other clinically significant or unstable conditions.
- Subject's participation in any other clinical study.
- Subjects dependent (as employee or relative) of the promoter or researcher.
- Subjects placed in an institution by virtue of an order issued by either judicial or administrative authorities.
- Limited legal capacity or incapacity.
- Pregnancy.
