• Emergency override permissions for critical care situations

Application Constants (constants.tsx)

• Core application configuration
• RESULTS_PER_PAGE_LIMIT for API pagination
• LocalStorageKeys for secure browser storage

Validation Utilities (validation.tsx)

• Form validation schemas using zod
• Healthcare system password and identifier validation

Implementation Patterns

Medical Permission Checking

// Role-based permission example
export const canAccessPatientData = (user: UserRead, patientId: string) => {
  return (
    hasPermission(user, "view_patient") ||
    isAssignedToPatient(user, patientId) ||
    isEmergencyOverride(user)
  );
};

Form Validation

// Vital signs validation example
export const validateVitalSigns = (vitals: VitalSigns) => {
  const schema = z.object({
    temperature: z.number().min(95).max(110),
    heartRate: z.number().min(30).max(200),
    bloodPressure: z.object({
      systolic: z.number().min(60).max(250),
      diastolic: z.number().min(40).max(150),
    }),
  });
  return schema.safeParse(vitals);
};
