Authors ' conclusions There is a paucity of evidence regarding how best to reduce corruption .
Promising interventions include improvements in the  detection and punishment of corruption  , especially efforts that are coordinated by an independent agency .
Other promising interventions include guidelines that prohibit doctors from accepting benefits from the pharmaceutical industry , internal control practice s in community health centres , and increased transparency and accountability for co-payments combined with reduced incentives for informal payments .
Key messages The review suggests that some strategies to fight corruption in the health sector can have an effect on corruption .
This study shows that these strategies may have led to fewer patients giving their doctors informal payments ( low certainty evidence ) . •
The study suggests that this may have changed doctors ' attitudes about the influence of pharmaceutical companies on their choice of medicines ( low certainty evidence ) . •
We do n't know what the effects of these strategies have on healthcare or people 's health , or if these strategies had any harmful effects .
Background Corruption is the abuse or complicity in abuse , of public or private position , power or authority to benefit oneself , a group , an organisation or others close to oneself ; where the benefits may be financial , material or non- material .
It is wide-spread in the health sector and represents a major problem .
Objectives Our primary objective was to systematic ally summarise empirical evidence of the effects of strategies to reduce corruption in the health sector .
Our secondary objective was to describe the range of strategies that have been tried and to guide future evaluations of promising strategies for which there is insufficient evidence .
The extent to which increased transparency alone reduces corruption is uncertain .
Interventions to reduce corruption in the health sector What is the aim of this review ?
The aim of this Cochrane review is to assess the effectiveness of strategies to reduce corruption in the health sector .
Corruption can occur in any area of the health sector , and happens when people abuse their own position to benefit themselves , their organisation , or other people close to them .
It can take many forms , including bribes , theft , or giving incorrect or inaccurate information deliberately .
It can take money away from healthcare , lead to poorer quality care and make access to healthcare unfair , and often affects poor people the hardest .
PQRS Participation, Inappropriate Utilization of Health Care Services, and Medicare Expenditures
Medicare ’s Physician Quality Reporting System ( PQRS ) is the largest quality -reporting system in the U.S. health care system and a basis for the new value-based modifier system for physician payment . The PQRS allows health care providers to report measures of quality of care that include both the process of care and physiological outcomes . Using a multivariate difference-in-differences model , we examine the relationship of PQRS participation to three cl aims -computable measures of inappropriate utilization of health care services and risk-adjusted per capita Medicare expenditures . The data are a national r and om sample of PQRS-participating providers matched to nonparticipating providers by zip code and caseload . We found few significant relationships in the overall analysis . However , the magnitude and statistical significance of the desirable associations increased in subgroups of providers and beneficiaries more prone to overutilization ( e.g. , males , older beneficiaries , beneficiaries treated in larger medical practice s or by nonphysicians , and practice s in rural areas ) , and among beneficiaries with heart conditions , diabetes , and eye problems
