While the explicit approach is appealing in many ways, most systematic reviewers fear that bias adjustments will introduce subjectivity and error rather than improve transparency. When the investigators have a belief about the magnitude and direction of bias, the default approach (depicted in the box) is to put forward a numerical estimate they believe to be wrong and then qualify it-for example, "We think the estimate may be high because these are the first trials of this intervention, and early trials tend to have exaggerated effect sizes." This approach makes it difficult to justify putting out a numerical estimate.Įxplicit adjustment for bias means that the pooled effect size estimate would take into account concerns about quality and be interpretable as the authors' best estimate of the effect. Judging by the effect size, they seem to be saying that an intervention decreases mortality, but they also seem to be saying not to trust that estimate. In the example in Box 1, the investigators have pooled five studies and propose a "fair" rating for the overall quality of this evidence. a Most systematic reviews take a less transparent approach. The idea is not new-in fact, it was proposed and debated at length in the late 1980s and early 1990s. These guidelines encourage Evidence-based Practice Centers to quantify biases. US payers were then asked specific questions about each section of the AMCP dossier.This is a chapter from " Methods Guide for Effectiveness and Comparative Effectiveness Reviews." Editors' Foreword US payers were asked to rate the usefulness of each section of the AMCP dossier on a scale of 0 to 10, where 0 is not useful at all and 10 is extremely useful. Interviews focused on how AMCP dossiers inform decision making and the usefulness of each dossier section. Participants included 7 medical directors and 3 pharmacy directors who were voting members or chairs of Pharmacy and Therapeutics (P&T) committees at a range of US health plans (national, regional, integrated) (Table 1). We then developed a discussion guide for use in one-on-one interviews. To characterize decision makers’ use of AMCP dossiers in granting reimbursement and formulary placement for new health technologies, we reviewed the published literature and third-party websites to identify how health care decision makers employ AMCP dossiers. Limited information has been published on the role of these dossiers in health care decision making. The dossier format guides manufacturers in presenting evidence for new pharmaceuticals, biologics, and vaccines to gain reimbursement and/or formulary placement in the United States (US) health care system. The Academy of Managed Care Pharmacy (AMCP) dossier format was introduced in 2000. ![]()
