Abstract
Introduction: A sizeable minority of commercially available blood glucose monitoring (BGM) systems fail to satisfy regulatory accuracy requirements, such as ISO 15197:2013, after approval. This study assessed whether the BGMs tested could consistently meet these ISO requirements by investigating their accuracy in a non-standardized setting.
Methods: In this 18-month post-market performance study, using the ISO criteria, healthcare professionals tested the accuracy of four CE-marked BGM systems (Roche Diabetes Care, Mannheim, Germany) on European adults with diabetes mellitus. ISO criteria included 95% of blood glucose (BG) values being within ± 15 mg/dl of a reference measurement for BG < 100 mg/dl or ± 15% for BG ≥ 100 mg/dl and, in the Parkes Consensus Error grid for type 1 diabetes comparing capillary BGM measurements versus reference method, 99% of BG values falling within zone A (no effect on clinical action or outcome) and zone B (altered clinical action with little or no effect on clinical outcome).
Results: BGM readings were obtained from 1650 participants, and the number of readings per BGM system was between 1712 and 2376. The percentage of BGM readings that fell within ISO 15197:2013 limits ranged from 99.4 to 99.9%. For all meter types, 100% of data points fell within zone A or zone B, and most data points for each meter (≥ 99.9%) were in zone A.
Conclusion: All four CE-marked BGM models showed results within the accuracy limits defined by ISO 15197 in a non-standardized setting and thus consistently met regulatory accuracy requirements.
期刊介绍:
Diabetes Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all areas of diabetes. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Diabetes Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
