The Value of Health Information Technology: Filling the Knowledge Gap

Robert S. Rudin, PhD; Spencer S. Jones, PhD; Paul Shekelle, MD, PhD; Richard J. Hillestad, PhD; and Emmett B. Keeler, PhD
Studies of health information technology have not kept up with the evolving needs of the healthcare system. We explain how to set them straight.
Unfortunately, we have found that few studies include both costs and benefits in their definitions of value. Most studies look at only short-term time horizons, which ignore many of the downstream benefits of the HIT, and many studies don’t even explicitly state to whom the value is accruing. To illustrate this, we present in Table 1 a sample of recent HIT articles, and whether and how they reported information on value (columns A through D). These articles are a purposive sample to capture a diversity of study types, including those that focus on 1 particular HIT installation as well as broader cross-sectional studies.

In this sample of 10 articles, 3 reported only on costs, without mention of any benefits, while 1 reported only on benefits, with no reporting on costs (which can include utilization). Thus, 4 of the 10 studies do not report both costs and benefits, and therefore cannot provide information about value (since value includes both costs and benefits). All of the studies are relatively short term, most having a time horizon of 1 to 3 years, and thus any downstream benefits or costs that might accrue due to better care today will not be captured. Only 1 study was explicit about “To whom does the value accrue?”, although in 3 others this could be inferred. These studies clearly show room for improvement in terms of how they measure value.

Even when information on costs, benefits, and perspective are presented, studies of HIT must then present sufficient information for readers to know what the intervention is, if readers are to be able to reach conclusions about whether the HIT system is something that could be implemented in another context. However, most evaluations of HIT do not adequately report such information. Few studies explain how the technology works, let alone how it was implemented. Furthermore, most studies don’t even report basic contextual information such as under what payment system the users were paid.

Studies need to open up the “black box” of HIT and do a better job explaining how HIT contributed to the results, including the role of key contextual factors. The need for particulars about the intervention details and implementation details has been noted by others for several years.4,34,35 All of these authorities recommend including at least 3 descriptors of the intervention: what the functionality does, contextual information, and implementation information. HIT evaluation studies need to describe this information so that a reader can understand what was being evaluated and assess whether or not they might be able to realize that value if they were to try to implement the same intervention in a different context.

To show how studies currently achieve this benchmark, we assessed the same 10 studies as above along these dimensions (Table 1, columns E, F, and G). All the studies had some description of the HIT functionalities, although for some this was at a very general and basic level (“a hospital EHR with CPOE [computerized physician order entry],” otherwise unspecified). Four studies report no contextual information at all, while in another 3, the only contextual data are the size of the organizations (usually a hospital). Only 3 studies reported some aspect of the financial status or payer mix. In 8 studies, there was no information about implementation. These data support, broadly, conclusions similar to those reached in a recent systematic review of HIT covering the years 2010-2013. In that review of 225 studies, only about a third of studies reported any information about context and implementation beyond the simplest measures.6

A PROPOSAL TO IMPROVE FUTURE HIT EVALUATIONS OF VALUE

Without more attention to the necessary measuring and reporting of the data needed to assess value, we risk the possibility of 3 more years’ worth of published studies, which we estimate would be more than 300 hypothesis-testing articles,6 that do not give us appreciably better knowledge about this crucial aspect of HIT: how best to realize value. We propose in Table 2 criteria that should be met by all reports of HIT studies that are intended to improve our understanding of value. These include using evaluations to include both costs and benefits, using longer time horizons, considering the perspectives of different stakeholders, and reporting implementation details and contextual variables.

Making these changes may require especially imaginative study designs, and research teams that have both quantitative and qualitative expertise. For example, more qualitative research will be required to assess such questions as: How were users of the HIT trained? Was the training likely effective? What kind of support was provided from organizational leadership? What exactly was the HIT product intended to do? To what extent were the end users involved in the design of the technology? Details like these are critical to determining the applicability of any particular study’s results to other settings. While an extensive body of qualitative literature shows how HIT may achieve benefits or result in unintended consequences, this literature is almost completely distinct from studies that assess value in terms of quantitative measures of efficiency, quality, and safety. It is therefore largely impossible, using the current literature, to both identify the successful implementations of HIT and understand how to replicate them.

Making such changes will not be easy, as ideas about what constitutes HIT research are entrenched. However, if research is to align with the current needs of the healthcare system, researchers should take on this challenge and produce results that not only prove what is possible, but also show how to achieve it.
