We thank Dr Yik Keng Yeong (Restart practice of random audits on clinics; May 20) and Mr Edmund Khoo Kim Hock (Use computer algorithms to find patterns indicating Chas fraud; May 18) for their suggestions to increase the audit capabilities of the authorities on private general practitioner and dental clinics.

The Ministry of Health (MOH) conducts regular audits on claims made under MOH schemes such as Medisave and the Community Health Assist Scheme (Chas) to ensure compliance with its rules and guidelines.

Random clinic inspections are also held to ensure compliance with MOH's guidelines on safety and standards of care.

The majority of Medisave- and Chas-accredited clinics audited comply with the rules.

When non-compliant claims are detected, MOH works with the clinics to rectify any issues.

Clinics with more severe non-compliance issues, such as irregular or fictitious claims, are flagged for further investigation. Appropriate course of action is taken, depending on the nature of the non-compliance.

Apart from clinic inspections and audits, MOH engages Medisave- and Chas-accredited clinics regularly via circulars, manuals, talks and on-site training sessions at the clinics, to familiarise them with the guidelines.

These will ensure that Medisave and Chas are used appropriately to support the needs of patients.
