Summary of "The cost-effectiveness of metformin in pre-diabetics: a systematic literature review of health economic evaluations."

ObjectivesOur aim was to systematically identify and appraise cost-effectiveness studies of metformin in prediabetic subjects.MethodsA systematic literature review was conducted and reported according to standard guidlines. The search was conducted in PubMed, Embase, International Society for Pharmacoeconomics and Outcomes Research (ISPOR) presentation database and the Cost-Effectiveness Analysis (CEA) and Centre for Reviews and Dissemination (CRD) registries. All cost-effectiveness studies assessing metformin in prediabetic patients were included.ResultsTwenty-three reports were included. Metformin and intensive lifestyle changes (ILC) interventions were always cost-effective compared to placebo. ILC was cost-effective and sometimes dominant compared to metformin. Metformin was cost-saving compared to ILC in the short and medium-term. Although, in the long term, metformin was more expensive than ILC in terms of direct medical costs, when indirect non-medical costs are included, metformin less expensive than ILC. One study reported that for patients with Body Mass Index (BMI) higher than 30 kg/m2, metformin is a cost-effective strategy compared to placebo and ILC. However, this finding was not confirmed by other retrieved studies.ConclusionILC is cost-effective compared to metformin and, both of them are cost-effective compared to placebo. Metformin may be cost-saving in the short- to medium-term and possibly in the long-term.

Medical and Biotech [MESH] Definitions

Organizations representing designated geographic areas which have contracts under the PRO program to review the medical necessity, appropriateness, quality, and cost-effectiveness of care received by Medicare beneficiaries. Peer Review Improvement Act, PL 97-248, 1982.

Published materials which provide an examination of recent or current literature. Review articles can cover a wide range of subject matter at various levels of completeness and comprehensiveness based on analyses of literature that may include research findings. The review may reflect the state of the art. It also includes reviews as a literary form.

Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.

An article or book published after examination of published material on a subject. It may be comprehensive to various degrees and the time range of material scrutinized may be broad or narrow, but the reviews most often desired are reviews of the current literature. The textual material examined may be equally broad and can encompass, in medicine specifically, clinical material as well as experimental research or case reports. State-of-the-art reviews tend to address more current matters. A review of the literature must be differentiated from HISTORICAL ARTICLE on the same subject, but a review of historical literature is also within the scope of this publication type.

The personal cost of acute or chronic disease. The cost to the patient may be an economic, social, or psychological cost or personal loss to self, family, or immediate community. The cost of illness may be reflected in absenteeism, productivity, response to treatment, peace of mind, QUALITY OF LIFE, etc. It differs from HEALTH CARE COSTS, meaning the societal cost of providing services related to the delivery of health care, rather than personal impact on individuals.
