Patient Name field is accepting numeric values

Issue Summary

The Patient Name field is accepting numeric values, which is invalid. Users can enter numbers (e.g., 211) without any validation, whereas the field should only accept alphabetic characters.

Problem Statement

• Patient Name field allows numeric input
• No validation to restrict numbers
• Invalid data is being stored in the system

Screenshot Steps to Reproduce:

1. Open the patient form
2. Enter "211" in the Patient Name field
3. Submit the form
4. Observe that it is accepted

Impact:

• Incorrect patient data
• Poor data quality

Proposed Solution

• Add validation to allow only alphabetic characters (A–Z, a–z)
• Reject numeric input using regex: ^[A-Za-z\s]+$
• Show error message: "Patient name must contain only letters"

Test-Driven Development

Acceptance Criteria

Scenario 1: Reject numeric input Given the user is on the patient form When the user enters "211" in the Patient Name field Then a validation error should be shown And the form should not be submitted

Scenario 2: Accept valid input Given the user is on the patient form When the user enters "Laxmi" in the Patient Name field Then the input should be accepted And the form should be submitted successfully

Test Cases

Test ID	Description	Steps	Expected Result
TC-001	Numeric input	Enter 211	Error shown
TC-002	Valid input	Enter Laxmi	Accepted
TC-003	Mixed input	Enter Laxmi123	Error shown

Implementation Details

• Add validation in PatientForm component
• Update frontend and backend validation
• Add unit tests for validation

Definition of Done

• Numeric values are rejected
• Validation error is shown
• Valid names are accepted
• Tests are passing
