Abstract
Background
There is considerable international interest in exploiting the potential of digital solutions to enhance the quality and safety of health care. Implementations of transformative eHealth technologies are underway globally, often at very considerable cost. [I believe it would be more accurate to write "always at considerable cost, with generous profits being made by the IT merchants, implementers and consultants"- ed.] In order to assess the impact of eHealth solutions on the quality and safety of health care, and to inform policy decisions on eHealth deployments, we undertook a systematic review of systematic reviews assessing the effectiveness and consequences of various eHealth technologies on the quality and safety of care.
Methods and Findings
We developed novel search strategies, conceptual maps of health care quality, safety, and eHealth interventions, and then systematically identified, scrutinised, and synthesised the systematic review literature. Major biomedical databases were searched to identify systematic reviews published between 1997 and 2010. Related theoretical, methodological, and technical material was also reviewed. We identified 53 systematic reviews that focused on assessing the impact of eHealth interventions on the quality and/or safety of health care and 55 supplementary systematic reviews providing relevant supportive information. This systematic review literature was found to be generally of substandard quality with regards to methodology, reporting, and utility. We thematically categorised eHealth technologies into three main areas: (1) storing, managing, and transmission of data; (2) clinical decision support; and (3) facilitating care from a distance. We found that despite support from policymakers, there was relatively little empirical evidence to substantiate many of the claims made in relation to these technologies. Whether the success of those relatively few solutions identified to improve quality and safety would continue if these were deployed beyond the contexts in which they were originally developed, has yet to be established. Importantly, best practice guidelines in effective development and deployment strategies are lacking.
Conclusions
There is a large gap between the postulated and empirically demonstrated benefits of eHealth technologies. [You've heard that here before - ed.]
In addition, there is a lack of robust research on the risks [I believe it would be more accurate to say there's been a suppression of research and/or of publicity on the risks - ed.] of implementing these technologies and their cost-effectiveness has yet to be demonstrated [in other words, healthcare IT is an experimental technology. You've heard that here before, too - ed.], despite being frequently promoted by policymakers and “techno-enthusiasts” as if this was a given.
[In other words, there's an irrational - or contrived - exuberance. You've heard that here before, too - ed.]
In the light of the paucity of evidence in relation to improvements in patient outcomes, as well as the lack of evidence on their cost-effectiveness, it is vital that future eHealth technologies are evaluated against a comprehensive set of measures, ideally throughout all stages of the technology's life cycle. [You've heard that here before, too - ed.]
Such evaluation should be characterised by careful attention to socio-technical factors to maximise the likelihood of successful implementation and adoption.
[You've heard that here before, too, as well as at my site "Contemporary Issues in Medical Informatics: Common Examples of Healthcare Information Technology Difficulties", as a matter of fact previously entitled "Sociotechnologic Issues in Medical Informatics...", started in 1999 - ed.]
