Regional/National Ele ctronic Health Records Cost-benefit analysis: a systematic review

1. Regional/National Electronic Health RecordsCost-benefit analysis:a systematic review Class 4 aturma4@gmail.com 4th June 2012

2. CONCEPTS: Electronic Health Records Introduction  “Media that facilitate transportability of pertinent information concerning patient's illness across varied providers and geographic locations. Some versions include direct linkages to online consumer health information that is relevant to the health conditions and treatments related to a specific patient” PubMed - MeSH, 2010  “Electronically stored and transmitted medical record that contains patientdemographics, medical history, lab tests, X-rays, scans, prescription lists, and any other relevant information” Wulsin, L. and Dougherty, A., 2008 Wulsin, L. and Dougherty, A., Health information technology - Electronic health records: a primer, California State Library, 2008 (http://www.library.ca.gov/crb/08/08-013.pdf) http://www.ncbi.nlm.nih.gov/mesh/68057286

3. CONCEPTS: Cost-Benefit Analysis Introduction “a method of comparing the cost of a program with its expected benefits in dollars (or other currency); the benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. Cost effectiveness compares alternative ways to achieve a specific set of results.”(PubMed – MeSH, 1976) http://mavit.kabunzo.com/tag/dolar/

4. EHR: Why so delayed? Introduction It is generally agreed that EHRs hold great promise for improving healthcare quality and efficiency But healthcare is decades behind other industries dealing with Information Technology adoption There is an urgent need for hospitals to adopt general EHR systems. However, the efforts of government and other EHR advocates have not sufficiently accelerated the diffusion trajectory. Lori T. Peterson et al., Assessing Differences Between Physicians’ Realized and Anticipated Gains from Electronic Health Record Adoption, 2009

8. Research Questions What is the return per unit of money spent on regional or national EHR systems?  Is this system financially supported by the government of each country where it was implemented? http://aep.ist.utl.pt/divulgacao/publicacoes/

9. Aim •  To review the published literature regarding the financial costs and benefits of regional or national Electronic Health Records. •  Find out which records characteristics are associated to a bigger investment return. •  Measure the differences relating to the return of investment between all regions. With this, we intend to…

10. Methods Systematic Review A systematic review is a method of identifying, appraising, and synthesising research evidence. The aim is to evaluate and interpret all available research that is relevant to a particular review question. In a systematic review, the scope (for example, the review question and any sub-questions and/or sub-group analyses) is defined in advance, and the methods to be used at each step are specified. The steps include: a comprehensive search to find all relevant studies; the use of criteria to include or exclude studies; and the application of established standards to appraise study quality.

31. Initial Investment and Cost Savings Results

32. Conclusions • In terms of cost savings, we studied them per year. • The investment from government or other entities was, in mean, 24 billion dollars, being the highest value from the USA, 77.8 billion dollars and the lowest 36500, also from USA (Massachusetts and New York). • Our data related to cost savings came from 13 articles that referred values varying from 81 billion dollars to 42000 dollars. • In mean, 22 billion dollars were saved per year with EHR. • With two exceptions (Korea and UK), all of this was related to USA medical institutions.

33. Conclusions • From this point of view, EHR appear as advantageous. However, when compared to the mean of investment, which is 24 billion, we observe that this is not that linear. • In terms of profit, the target articles almost didn’t contain this type of information. Just some of them stated that the profit was 11billion, 20-30 billion, 1-2 million or 154,900 per year.

34. Conclusions • One of the main limitations to our project was the lack of relevant information in the final articles selected • The access to the full-text of many articles was denied and when asking the authors to provide us their articles, the majority did not answer us • The variables related to monetary values, such as initial cost investment, cost savings and profit, did not gathered information in every article

35. Conclusion From our systematic review, because the major barriers to adoption of EHRs are financial, we suggest that hospitals in better financial position with regard to liquidity, profitability and human resources efficiency will be more likely to adopt EHRs.
