The Centers for Medicare and Medicaid Services has collected data as of July about healthcare providers that have attested that they meet the first stage of meaningful use, offering a glimpse of the experience of early adopters of certified electronic health records. One of the findings showed that providers used required EHR functions with a higher percentage of patients than was called for in the requirements, according to CMS officials. About 77,000 healthcare providers have registered for the Medicare and Medicaid EHR incentive program, according to CMS findings about meaningful use participation. Twenty-one states have launched their Medicaid EHR program, with Arizona, Connecticut, Rhode Island and West Virginia in the past month. Among preliminary data, 2,383 physicians and other eligible professionals had verified that they met meaningful use requirements under the Medicare program, with 137 attesting unsuccessfully. The analysis did not explain why those providers failed attestation, but the agency will drill down to find the reason behind the numbers. However, 100 hospitals have attested and all have done so successfully.
