In this contract, the HealthRecord struct represents a patient's health record, and it includes various data points such as recordID, patientName, age, diagnosis, treatment, medications, and isAdmitted. The addHealthRecord function allows adding a new health record to the repository, while the getPatientRecords and getRecordByID functions enable retrieving records for a specific patient or by a specific record ID.
The patientRecords mapping stores an array of HealthRecord for each patient's address, allowing the contract to store health records for multiple patients.
