[0002] Medical safety incidents refer to unsafe hazards, conditions or negative events with consequences that are discovered by staff in medical institutions or occur during the process of diagnosis and treatment of patients, which are caused by various factors other than the natural course of the patient's own disease. In the field of radiotherapy, research reports show that most of the incidents are currently caused by human errors during the execution of the radiotherapy process.

[0083] In a preferred embodiment of the present invention, the event reporting information includes: time of occurrence, patient name / ID (involving patient information), reporter information, department where the event occurred, event type, detailed description of the event information, reporting handler, etc.

[0084] Specifically, event reporting refers to the reporting of an incident by a person who has experienced a radiotherapy safety incident during the radiotherapy process. The reporting link is the most important and most difficult process to complete accurately in the entire management process. The quality and quantity of event reporting information are crucial to the implementation of subsequent processes. Therefore, the accuracy and authenticity of event reporting information must be guaranteed.

[0085] Specifically, this embodiment performs a database search on the fields of the event reporting information to ensure the authenticity of the information, performs an accuracy check on the event type field, and checks whether the field is accurate by checking whether there is patient information in the event reporting information. For untrue and inaccurate fields, an alarm message is fed back to prompt the reporter to confirm and conduct a secondary check.

[0086] S2, performing a word segmentation and summarization operation on the event report information to determine several event keywords of the event report information;

[0087] Preferably, the fields of the event reporting information further include: a detailed description of the event;

[0088] The performing of a word segmentation and summarization operation on the event report information to determine a number of event keywords of the event report information includes:

[0089] S21, segmenting the event detailed description to generate a number of keywords to be identified in the event report information, and determining the frequency of each keyword to be identified in the event detailed description;

[0093] In a preferred embodiment of the present invention, the subject keywords include: "death", "disability", "severe", "moderate", "injury", "dysfunctional disorder", "serious", "general", etc. When processing reported event information, the text needs to be segmented to facilitate information extraction and analysis. This embodiment adopts commonly used word segmentation algorithms, including: dictionary-based matching algorithms, statistics or machine learning-based algorithms, etc. The continuous text is divided into several keywords to be identified, and the word frequency of each keyword to be identified in the detailed description of the event is counted. Secondly, the keywords to be identified are converted into corresponding word vectors, and the cosine similarity between the word vectors of the keywords to be identified and the word vectors of the subject keywords is calculated, and then the keywords to be identified are classified according to the cosine similarity using the K-means clustering algorithm and the hierarchical clustering algorithm.

[0094] Finally, the weight of each keyword set is determined according to the word frequency of each keyword to be identified in each keyword set, and the subject keywords of the keyword set that are higher than a preset weight threshold are used as several event keywords of the event reporting information.

[0095] S3. According to the event keyword, determine a number of target historical event reporting information matching the event keyword from a preset event database;

[0096] Preferably, the determining, based on the event keyword, a number of target historical event reporting information matching the event keyword from a preset event database includes:

[0097] S31, obtaining historical event keywords of each historical event reporting information in the event database;

[0098] S32, traversing the event keywords, adding the historical event reporting information corresponding to the historical event keyword that is the same as the currently traversed event keyword to the event set of the currently traversed event keyword;

[0099] S33. When the traversal is completed, an event intersection of each of the event sets is generated, and the historical event reporting information in the event intersection is used as the target historical event reporting information.

[0100] In a preferred embodiment of the present invention, by generating an event set of each event keyword and then taking the union thereof, target historical event report information simultaneously containing all event keywords of the event report information is determined.

[0101] S4. Determine the event risk level, event occurrence probability, and event malignancy of the event reporting information according to the event reporting information and the target historical event reporting information;

[0102] Preferably, determining the event risk level, event occurrence probability, and event malignancy of the event reporting information according to the event reporting information and the target historical event reporting information includes:

[0103] S41, obtaining the historical risk level, historical occurrence time, and accident level of the security accident caused by each target historical event reporting information;

[0104] S42, calculating the risk average value of the historical event risk levels, and using the risk average value as the event risk level of the event reporting information;

[0106] S44, calculating the accident average value of the accident level, and generating the event malignancy degree of the event reporting information from the accident average value.

[0107] In a preferred embodiment of the present invention, the event risk levels and their corresponding expressions are shown in the following table:

[0108]

[0109] First, based on the historical risk level assessed by experts in the target historical event reporting information, the average value is calculated to determine the event risk level of the event reporting information; secondly, based on the event occurrence time of the target historical event reporting information, the number of target historical event reporting information reported weekly within one year is determined; when the average value of the number of target historical event reporting information reported weekly exceeds the preset high frequency threshold, the event occurrence probability of the event reporting information is determined to be high; when the average value of the number of target historical event reporting information reported weekly does not exceed the high frequency threshold but exceeds the preset low frequency threshold, the event occurrence probability of the event reporting information is determined to be medium; when the average value of the number of target historical event reporting information reported weekly does not exceed the low frequency threshold, the event occurrence probability of the event reporting information is determined to be low; finally, the event malignancy of the event reporting information is determined by the average value of the accident levels of the actual security accidents caused by each of the target historical event reporting information;

[0110] S5. Generate an event analysis result according to the event risk level, the event occurrence probability, the event malignancy, and the target historical event reporting information.

[0111] In a preferred embodiment of the present invention, an event analysis result is generated based on the event risk level, the event occurrence probability, the event malignancy, and the target historical event reporting information, so as to provide specific data basis for subsequent planning of rectification strategies for radiotherapy safety events, inferring root causes, or analyzing process loopholes.

[0112] Specifically, managers can use IDT decision tree analysis tools, RCA root cause analysis tools, fishbone diagram analysis tools, group voting analysis tools and other cause analysis tools to analyze the root causes of radiotherapy safety incidents based on the event analysis results and find loopholes or defects in safety management. When analyzing the responsibility of an incident, responsibilities should be divided differently based on the impact of the incident, the frequency of occurrence, etc. For incidents with higher risk levels, a special investigation team should be established to conduct investigation, analysis and handling.

[0113] When formulating quality management measures for corresponding events, we should prevent such events from happening or reduce their probability. Departments should formulate corresponding rectification measures and quality management plans based on the defects or loopholes in the causes of events, risk prevention and control, etc. reflected by (adverse) events, formulate special audit systems, and arrange for special personnel to audit the implementation of rectification plans. Rectification measures are generally divided into three types, namely correction, corrective measures and preventive measures. For events with a risk level of 0-1 points, corrections can be made. For events with a risk level of 2-4 points, corrective measures and preventive measures should be formulated.

[0114] Finally, the cause analysis, processing results and other information of the incident are announced to all department personnel and fed back to the department where the (adverse) incident occurred to enhance the safety awareness of relevant personnel and prevent such incidents from happening again. At the same time, all the processing information of the incident is entered into the database to provide a basis for the optimization of quality management measures or risk assessment in the future. The establishment of this link can make the (adverse) incident reporter feel the leadership, enhance everyone's enthusiasm for reporting (adverse) incidents, and play a positive role in creating a good department culture of defect management in the department.

[0115] This embodiment provides an event analysis method for radiotherapy safety events, which obtains event report information of radiotherapy safety events, and then performs word segmentation and induction operations on the event report information to determine several event keywords of the event report information; according to the event keywords, several target historical event report information matching the event keywords are determined from a preset event database; according to the event report information and the target historical event report information, the event risk level, event occurrence probability, and event malignancy of the event report information are determined, and finally, according to the event risk level, event occurrence probability, event malignancy, and target historical event report information, an event analysis result is generated. Therefore, the present invention matches several historical event report information related to the event report information through event keywords, and then generates an event analysis result of the event report information according to the target historical event report information, thereby improving the efficiency of event analysis and providing a data basis for the subsequent timely response and improvement of radiotherapy safety events.
