In 2008, Public Procurement Law (PPL) was amended to implement and regulate e-Procurement in Turkey. Non-private, public purchaser hospitals are obliged to enter tender results of their medical device purchases into e-procurement system (EPS) to be eligible for a reimbursement by the Social Security Institution (SSI) in Turkey. Objectives of this research are to examine the impact of the EPS that is currently being used for medical device purchases in Turkey since 2011; and to investigate how the system is being used to define ceiling prices for reimbursement, concurrently assessing the quality and quantity of data uploaded by hospitals. EPS data is downloaded on a GMDN basis from Turkish National Database for Medical Devices, (TITUBB) which is an e-catalogue system that was launched to provide barcode level product registration, search and the e-procurement results. In accordance with the objectives, assessment is conducted on more than ten GMDNs and results are utilized to see the effect of EPS on pricing, comparing the prices on officially published SSI positive lists. Our study shows that a lowest price detected on EPS could be set as the reimbursement price, as was the case for the product; aortic stent graft, contralateral limb, where a defined SSI positive list price was reduced after determination of a lower price on EPS, on account of  a mispriced tender record. An extrapolation while searching out the reimbursement prices is needed instead of SSI’s calculations based on merely a retrospective and detection of lowest price practice. Effectiveness of this policy depends on resolving the weaknesses of EPS data in terms of quality and quantity; a misdated tender or a mispriced product could be a ground for an erroneous price setting and tenders that are not recorded at all or deferred might lead to incomplete EPS data to define reimbursement prices.
