“I like SRDR’s use of the Tabs and the separation by topic area of the Tabs; it allows for focus on sections of a paper at a time. SRDR is powerful and adaptable, provides a way to standardize diverse results, and provides structure.“

“SRDR is one of the few data systems designed specifically for producing and archiving systematic reviews with the intention to share the data with the public. It’s extremely flexible and it allows users to design their forms (and data items on the forms) in a way that best suit their needs and workflow.”

“The structure of SRDR lends itself well to teaching metacognitive processes associated with linking the discrete steps of the evidence analysis process. Another benefit is the flexibility of SRDR to handle diagnostic accuracy as well as etiology, treatment, and prognosis questions during systematic reviews.”

Obstructive Sleep Apnea: CPAP and AHI vs. outcomes
73 Studies • 2 Key Questions • 2 Extraction Forms
Objectives: Purpose of the Review: The Centers for Medicare and Medicaid Services (CMS) nominated the topic to the Agency for Healthcare Research and Quality for a Technology Assessment. The scope of the report’s protocol was developed to inform CMS’s coverage decisions. The report will address contextual questions (CQs) and conduct a systematic review (SR). The CQs cover background material to help to understand the findings of the SR, including information on currently-used treatment modalities for OSA, the postulated rationales for use of CPAP, currently-used measures of AHI and related measures in contemporary research and clinical settings, validated sleep questionnaires. The CQs also cover discussion of the ideal study designs for establishing validity of surrogate or intermediate measures. The CQs will be addressed using a, best-evidence, but nonsystematic approach. The SR will (1) summarize evidence on the validity of measures of sleep and breathing as surrogates (or intermediate outcomes) for clinically significant outcomes in patients with OSA, effectively assessing the linkage between the former and the latter, and (2) synthesize evidence on the (comparative) efficacy, effectiveness and safety of CPAP to prevent clinically important outcomes. The SR will attempt to describe heterogeneity of treatment effects in terms of diversity of patient populations, devices and treatment protocols, outcome definitions and study design characteristics. For included randomized controlled trials (RCT), we will examine the concordance among AHI (and similar measures), validated sleep questionnaires, and clinical outcomes. The intended audience includes CMS and non-CMS stakeholders including guideline developers, clinicians and other providers of care for patients with OSA, healthcare policy makers, and patients.
