ObjectiveTo review international policies to control expenditure on pharmaceuticals by influencing the behaviour of patients and providers and regulating the pharmaceutical industry.MethodSystematic review of experimental and quasi-experimental studies. Published studies were identified with an electronic search strategy using MEDLINE and EMBASE from 1980 to May 2012. Studies were eligible if they assessed the effect of policies aimed at influencing the behaviour of patients and providers, and regulating the pharmaceutical industry. Outcome measures included pharmaceutical expenditure, prices or utilization; other resource use relating to pharmaceuticals; and health outcomes and patients’ or providers’ behaviour relating to pharmaceutical use. Quality assessment criteria for each study design were developed based on the standard criteria recommended by the Cochrane Effective Practice and Organisation of Care (EPOC) group.The review includes studies based on randomized controlled trials and rigorous quasi-experimental designs (interrupted time-series and controlled before-and-after studies). Studies were excluded if they were conducted within a single hospital or practice; related to pharmaceutical care services or disease management; had less than 6 months of follow-up period (or less than 12 months overall for interrupted time series); if data in controlled before-and-after studies were not collected contemporaneously or if no rationale was stated for the choice of control group; or if relevant and interpretable data were not presented.ResultsA total of 255 studies met the inclusion criteria for this review. The majority of the studies relating to patients evaluated cost sharing interventions such as user charges (52 studies). User charges do reduce utilization of pharmaceuticals, and reduce public expenditure by shifting costs to patients. But they reduce the use of essential as well as non-essential drugs, and without adequate exemptions they affect vulnerable groups disproportionately.The majority of studies relating to doctors evaluated the effects of educational approaches (78 studies), reimbursement restrictions (48 studies) and incentive systems (22 studies). Evidence on these policies is of mixed quality. It appears possible to influence prescribing modestly, through various means, but it is essential that messages to prescribers are based on good evidence of effectiveness and cost-effectiveness.Twenty-nine studies related to industry regulation, and they were of mixed quality. Evidence from studies of reference pricing suggests that this may result in cost savings. These are, however, achieved not by companies reducing or restraining prices, or by reductions in the overall volume of prescriptions, but by some shifts in use and shifting costs to patients, with consequent adverse effects on the equity of access to medicines. Other price and profit controls remain almost completely lacking in evaluative evidence.ConclusionsIt may be that the undesirable consequences of policies influencing patients, partic...

A high portion of AF/AFL patients with CHADS2 score ≥2 were undertreated with warfarin. As ischemic stroke is one of the leading causes of death in Korea, a more aggressive approach to prevent stroke in patients with AF/AFL is required.

The term continuity of care (COC) reflects how patients experience healthcare over time in a coherent and connected manner (Haggerty et al., 2003). Existing evidence suggests that implementation of COC could be associated with improvements in preventive services, chronic disease management, and patient or doctor satisfaction; moreover, it could lower specialist services use, mortality and healthcare costs (
