How can I design a query using SOQL for designing medical records of patients?
I am a Salesforce developer currently working on a custom search functionality for a healthcare organization’s patient management system. The system includes a custom object called “Medical_Record__C” which stores detailed information about patients' medical history. How can I use THE SOQL contains keyword for constructing a query to search for patients who are taking “Aspirin” medicine for their treatment?
In the context of Salesforce, you can construct a SOQL query by using the CONTAINS” keyword to search for the patient who is currently taking the medication “Aspirin” within their medic records by using the following approach:-
Firstly, you won't need to create an apex class called “PatientSearchController” –
Public class PatientSearchController {
Public List searchPatientsWithAspirin() {
// Perform the SOQL query to search for patients with Aspirin in their medical records
List patientsWithAspirin = [
SELECT Id, Name,
(SELECT Id, Medication__c FROM Medical_Records__r WHERE CONTAINS(Medication__c, ‘Aspirin’))
FROM Patient__c
];
Return patientsWithAspirin;
}
}Next, you would be need to create a Visualforce page ‘PatientSearchPage’ for displaying the search results:-
Here is the java based coding structure given:-
Import java.util.ArrayList;
Import java.util.List;
Class Patient {
Private String id;
Private String name;
Private List medicalRecords;
Public Patient(String id, String name) {
This.id = id;
This.name = name;
This.medicalRecords = new ArrayList<>();
}
Public void addMedicalRecord(MedicalRecord record) {
medicalRecords.add(record);
}
Public List getMedicalRecords() {
Return medicalRecords;
}
Public String getId() {
Return id;
}
Public String getName() {
Return name;
}
}
Class MedicalRecord {
Private String id;
Private String medication;
Public MedicalRecord(String id, String medication) {
This.id = id;
This.medication = medication;
}
Public String getId() {
Return id;
}
Public String getMedication() {
Return medication;
}
}
Public class PatientSearch {
Public List searchPatientsWithMedication(List patients, String medicationName) {
List patientsWithMedication = new ArrayList<>();
For (Patient patient : patients) {
For (MedicalRecord record : patient.getMedicalRecords()) {
If (record.getMedication().toLowerCase().contains(medicationName.toLowerCase())) {
patientsWithMedication.add(patient);
break; // Break to avoid adding the same patient multiple times if they have multiple matching records
}
}
}
Return patientsWithMedication;
}
Public static void main(String[] args) {
// Create sample patients and medical records
Patient patient1 = new Patient(“P001”, “John Doe”);
Patient1.addMedicalRecord(new MedicalRecord(“MR001”, “Aspirin”));
Patient1.addMedicalRecord(new MedicalRecord(“MR002”, “Ibuprofen”));
Patient patient2 = new Patient(“P002”, “Jane Smith”);
Patient2.addMedicalRecord(new MedicalRecord(“MR003”, “Paracetamol”));
Patient2.addMedicalRecord(new MedicalRecord(“MR004”, “Aspirin”));
List patients = new ArrayList<>();
Patients.add(patient1);
Patients.add(patient2);
// Search for patients taking a specific medication
PatientSearch patientSearch = new PatientSearch();
List patientsTakingAspirin = patientSearch.searchPatientsWithMedication(patients, “Aspirin”);
// Display the search results
System.out.println(“Patients taking Aspirin:”);
For (Patient patient : patientsTakingAspirin) {
System.out.println(“Patient ID: “ + patient.getId() + “, Name: “ + patient.getName());
}
}
}
Here is the Python based coding structure given:-
Class Patient:
Def __init__(self, id, name):
Self.id = id
Self.name = name
Self.medical_records = []
Def add_medical_record(self, medical_record):
Self.medical_records.append(medical_record)
Class MedicalRecord:
Def __init__(self, id, medication):
Self.id = id
Self.medication = medication
Class PatientSearch:
Def search_patients_with_medication(self, patients, medication_name):
Patients_with_medication = []
For patient in patients:
For record in patient.medical_records:
If medication_name.lower() in record.medication.lower():
Patients_with_medication.append(patient)
Break # Break to avoid adding the same patient multiple times if they have multiple matching records
Return patients_with_medication
# Create sample patients and medical records
Patient1 = Patient(“P001”, “John Doe”)
Patient1.add_medical_record(MedicalRecord(“MR001”, “Aspirin”))
Patient1.add_medical_record(MedicalRecord(“MR002”, “Ibuprofen”))
Patient2 = Patient(“P002”, “Jane Smith”)
Patient2.add_medical_record(MedicalRecord(“MR003”, “Paracetamol”))
Patient2.add_medical_record(MedicalRecord(“MR004”, “Aspirin”))
Patients = [patient1, patient2]
# Search for patients taking a specific medication
Patient_search = PatientSearch()
Patients_taking_aspirin = patient_search.search_patients_with_medication(patients, “Aspirin”)
# Display the search results
Print(“Patients taking Aspirin:”)
For patient in patients_taking_aspirin:
Print(“Patient ID:”, patient.id, “, Name:”, patient.name)
