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.
