Furthermore, contrive incentive mechanisms in the "sampling audit and payment process" to make the healthcare providers willing to apply for their medical claim payments straightforwardly. A framework of "medical claim payment auditing by double sampling plan (MCPAD)" procedure based on the lot-by-lot double sampling plan was proposed to curb the growth of medical expenses. The proposed procedure entertains several advantages, including: (1) it meets international standards of sampling plan; (2) it simplifies the auditing process; (3) it reduces sample size and auditing costs; and (4) it encourages healthcare providers using an honest medical claim payment through the incentive mechanisms.

Practically, the proposed MCPAD procedure is also applied to healthcare provider. It is anticipated that the proposed procedure in other nations in the future.
