.. While some studies suggest improvements in patient safety can be made, others have found no effect. Instances of health IT–associated harm have been reported. However, little published evidence could be found quantifying the magnitude of the risk.
Several reasons health IT–related safety data are lacking include the absence of measures and a central repository (or linkages among decentralized repositories) to collect, analyze, and act on information related to safety of this technology. Another impediment to gathering safety data is contractual barriers (e.g., nondisclosure, confidentiality clauses) that can prevent users from sharing information about health IT–related adverse events. These barriers limit users’ abilities to share knowledge of risk-prone user interfaces, for instance through screenshots and descriptions of potentially unsafe processes. In addition, some vendors include language in their sales contracts and escape responsibility for errors or defects in their software (i.e., “hold harmless clauses”). The committee believes these types of contractual restrictions limit transparency, which significantly contributes to the gaps in knowledge of health IT–related patient safety risks. These barriers to generating evidence pose unacceptable risks to safety.[IOM (Institute of Medicine). 2012. Health IT and Patient Safety: Building Safer Systems for Better Care (PDF). Washington, DC: The National Academies Press, pg. S-2.]

… “For example, the number of patients who receive the correct medication in hospitals increases when these hospitals implement well-planned, robust computerized prescribing mechanisms and use barcoding systems. But even in these instances, the ability to generalize the results across the health care system may be limited. For other products— including electronic health records, which are being employed with more and more frequency— some studies find improvements in patient safety, while other studies find no effect.
More worrisome, some case reports suggest that poorly designed health IT can create new hazards in the already complex delivery of care. Although the magnitude of the risk associated with health IT is not known, some examples illustrate the concerns. Dosing errors, failure to detect life-threatening illnesses, and delaying treatment due to poor human–computer interactions or loss of data have led to serious injury and death.”

... In summary, the results of this data review suggest significant clinical implications and public safety issues surrounding Health Information Technology. The most commonly reported H-IT safety issues included wrong patient/wrong data, medication administration issues, clinical data loss/miscalculation, and unforeseen software design issues; all of which have varying impact on the patient’s clinical care and outcome, which included 6 death and 43 injuries. The absence of mandatory reporting enforcement of H-IT safety issues limits the number of relevant MDRs and impedes a more comprehensive understanding of the actual problems and implications.

Limitations of the MAUDE search and final subset of MDRs include the following:

1. Not all H-IT safety issue MDRs can be captured due to limitations of reporting practices including

... (a) Vast number of H-IT systems that interface with multiple medical devices currently assigned to multiple procodes making it difficult to identify specific procodes for H-IT safety issues;
... (b) Procode assignments are also affected by the ability of the reporter/contractor to correctly identify the event as a H-IT safety issue;
... (c) Correct identification by the reporter of the suspect device brand name is challenged by difficulties discerning the actual H-IT system versus the device it supports.
2. Due to incomplete information in the MDRs, it is difficult to unduplicate similar reports, potentially resulting in a higher number of reports than actual events.
3. Reported death and injury events may only be associated with the reported device but not necessarily attributed to the device.

4 Correct identification by the reporter of the manufacturer name is convoluted by the inability to discern the manufacturer of the actual H-IT system versus the device it supports.
5 The volume of MDR reporting to MAUDE may be impacted by a lack of understanding the reportability of H-IT safety issues and enforcement of such reporting.

... In the past two years, we have received 260 reports of HIT-related malfunctions with the potential for patient harm – including 44 reported injuries and 6 reported deaths. Because these reports are purely voluntary, they may represent only the tip of the iceberg in terms of the HIT-related problems that exist.

Even within this limited sample, several serious safety concerns have come to light. The reported adverse events have largely fallen into four major categories: (1) errors of commission, such as accessing the wrong patient’s record or overwriting one patient’s information with another’s; (2) errors of omission or transmission, such as the loss or corruption of vital patient data; (3) errors in data analysis, including medication dosing errors of several orders of magnitude; and (4) incompatibility between multi-vendor software applications and systems, which can lead to any of the above.
