HospitalOPD

This dataset contains anonymized event log records of patients who visited the Outpatient Department (OPD) of a healthcare facility for medical consultation and related clinical services. The dataset captures the chronological progression of patients through different healthcare service points and records timestamps associated with each activity performed during the patient journey. The primary objective of this dataset is to support research in process mining, workflow analysis, healthcare operations management, bottleneck identification, workflow graph construction, and predictive process monitoring. The dataset consists of 62,422 patient-event records collected between April 2024 and April 2026. Each record represents a patient's interaction with one or more OPD services and includes activity start and completion timestamps, enabling the reconstruction of complete patient pathways.Patient Workflow Every patient enters the OPD through an appointment or registration process and subsequently follows one or more healthcare service pathways depending on clinical requirements. The possible workflow activities include: Appointment/Registration Consultation (Prescription Issuance) Laboratory Investigation Medical Imaging Pharmacy/Medication Dispensing Patients may follow different process variants, including: Appointment → Consultation Appointment → Consultation → Laboratory Appointment → Consultation → Imaging Appointment → Consultation → Laboratory + Imaging Appointment → Consultation → Pharmacy Appointment → Consultation → Laboratory + Pharmacy Appointment → Consultation → Imaging + Pharmacy The dataset explicitly stores these variants using workflow codes and workflow names. Data Characteristics Domain: Healthcare Process Management Data Type: Event Log Records: 62,422 Observation Period: April 2024 – April 2026 Process Instances: Patient visits Activities: Appointment, Consultation, Laboratory, Imaging, Pharmacy Format: CSV Privacy: All patient identifiers have been anonymized and no personally identifiable information (PII) is included.本数据集收录了某医疗机构门诊部（Outpatient Department，简称OPD）患者就医及相关临床服务的匿名化事件日志记录，记录对象为前往该门诊部接受医疗咨询与临床服务的患者。该数据集记录了患者在不同医疗服务节点间的时序就诊路径，并留存了患者就医全流程中每一项操作的关联时间戳。 本数据集的核心应用目标为支撑流程挖掘、工作流分析、医疗运营管理、瓶颈识别、工作流图谱构建以及预测性流程监控领域的相关研究。 本数据集共包含62422条患者事件记录，采集周期为2024年4月至2026年4月。每条记录对应一名患者与一项或多项门诊部服务的交互行为，同时记录了对应操作的启动与完成时间戳，可完整复现患者的就医路径。 ## 患者就诊工作流 所有患者均通过预约或挂号流程进入门诊部，后续将根据临床需求选择一条或多条医疗服务路径。可支持的工作流操作类型包括： - 预约/挂号（Appointment/Registration） - 问诊（含处方开具）（Consultation (Prescription Issuance)） - 实验室检验（Laboratory Investigation） - 医学影像检查（Medical Imaging） - 药房配药/药品发放（Pharmacy/Medication Dispensing） 患者可遵循多种流程变体，具体如下： - 预约 → 问诊 - 预约 → 问诊 → 实验室检验 - 预约 → 问诊 → 医学影像检查 - 预约 → 问诊 → 实验室检验与医学影像检查 - 预约 → 问诊 → 药房配药 - 预约 → 问诊 → 实验室检验与药房配药 - 预约 → 问诊 → 医学影像检查与药房配药 本数据集通过工作流编码与工作流名称的形式，显式存储了上述各类流程变体。 ## 数据特征 - 应用领域：医疗流程管理 - 数据类型：事件日志（Event Log） - 记录条数：62422 - 观测周期：2024年4月至2026年4月 - 流程实例：患者就诊行为 - 操作类型：预约、问诊、实验室检验、医学影像、药房配药 - 数据格式：CSV - 隐私保护：所有患者标识均已完成匿名化处理，未包含任何个人可识别信息（Personally Identifiable Information，简称PII）。
