Abstract
Description
Technical Field
[0001] This invention relates to the field of medical data processing technology, specifically to a multi-parameter accelerated recovery assessment method for postoperative ERAS management of gastric cancer. Background Technology
[0002] Enhanced Recovery After Surgery (ERAS), proposed and implemented by Danish researchers, refers to a series of evidence-based optimized treatment measures adopted during the perioperative period to promote rapid patient recovery. These measures aim to reduce psychological and physiological trauma and stress responses, thereby reducing complications, shortening hospital stays, lowering in-hospital risks, and ultimately reducing medical costs. ERAS is a multidisciplinary management model that integrates optimized clinical pathways throughout the entire treatment process—pre-hospitalization, pre-operative, intra-operative, and post-operative—with a core emphasis on a patient-centered approach to care.
[0003] The recovery process for patients after gastric cancer surgery is complex, involving multiple dimensions such as physiological function recovery, nutritional status, pain management, and complication prevention. Traditional ERAS management often relies on the clinical experience of medical staff and manual records, which has the following problems:
[0004] It is highly subjective, lacks quantitative standards for judging whether patients have met the criteria, is easily influenced by the doctor's personal experience, and is difficult to comprehensively consider multi-dimensional data such as laboratory indicators, vital signs, pain scores and activity levels, resulting in poor postoperative rehabilitation management for gastric cancer patients. Summary of the Invention
[0005] The purpose of this invention is to provide a multi-parameter accelerated recovery assessment method for postoperative ERAS management of gastric cancer. This method eliminates the lack of quantitative standards for judging whether a patient has met the target criteria. It can simultaneously consider multi-dimensional data such as laboratory indicators, vital signs, pain scores, and activity levels, thereby improving the postoperative rehabilitation management effect of gastric cancer patients and solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] After acquiring multi-source data from patients following gastric cancer surgery using a data acquisition terminal, the multi-source data is preprocessed and fused using edge computing to form fused data from patients following gastric cancer surgery.
[0009] A multi-parameter accelerated recovery assessment model is constructed based on artificial intelligence. The fusion data of patients after gastric cancer surgery is analyzed and identified according to the multi-parameter accelerated recovery assessment results of patients after gastric cancer surgery, so as to realize dynamic risk assessment of patients' postoperative gastric cancer recovery.
[0010] Preferably, multi-source data from patients after gastric cancer surgery is acquired based on a data acquisition terminal, including:
[0011] Real-time monitoring of heart rate, respiratory rate, blood pressure, blood oxygen saturation, body temperature, electrocardiogram waveform, blood routine, C-reactive protein, procalcitonin, electrolytes and liver and kidney function of patients after gastric cancer surgery, to obtain vital signs and physiological signals of patients after gastric cancer surgery;

[0015] Real-time monitoring of patients' emotional state, confidence in recovery, cognitive function and social support after gastric cancer surgery to obtain the patients' psychosocial psychological state after gastric cancer surgery.
[0016] Based on the patient's vital signs, physiological signals, activity level, functional indicators, nutritional status, metabolic indicators, subjective reports of pain symptoms, and psychosocial status after gastric cancer surgery, multi-source data on the patient's postoperative gastric cancer surgery are generated.

[0023] The missing and outlier values in the multi-source data of patients after gastric cancer surgery were evaluated to determine whether the missing and outlier values in the multi-parameter accelerated recovery assessment of patients after gastric cancer surgery were valuable.
[0024] When missing values and outliers in multi-source data after gastric cancer surgery are valuable for the patient's multi-parameter accelerated recovery assessment, missing values are filled and outliers are corrected; otherwise, missing values and outliers are deleted.
[0025] The multi-source data of patients after gastric cancer surgery were standardized. Specifically, the multi-source data of patients after gastric cancer surgery with different dimensions were normalized and mapped to the [0,1] interval to remove the dimensional differences between the multi-source data of patients after gastric cancer surgery, thus forming standardized multi-source data of patients after gastric cancer surgery.
[0026] Preferably, the following operations are performed to fuse and analyze multi-source data from patients after gastric cancer surgery based on edge computing:

[0032] The multi-parameter accelerated recovery assessment model was tested using a test set to evaluate its generalization performance and determine whether it could achieve the expected effect of automating the assessment of multi-parameter accelerated recovery after gastric cancer surgery.
[0033] When the multi-parameter accelerated recovery assessment model fails to achieve the expected effect of automatically assessing the multi-parameter accelerated recovery status of patients after gastric cancer surgery, the parameters of the multi-parameter accelerated recovery assessment model are adjusted and optimized until the multi-parameter accelerated recovery assessment model can achieve the expected effect of automatically assessing the multi-parameter accelerated recovery status of patients after gastric cancer surgery, and the optimal multi-parameter accelerated recovery assessment model is determined.
