Physicians in small physician-owned practices in the United States have been slower to adopt EHRs than physicians in large practices or practices owned by large organizations. The Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 included provisions intended to address many of the potential barriers to EHR adoption cited in the literature, including a financial incentives program that has paid physicians and other professionals $13 billion through December 2015.
Given the range of factors that may be influencing physicians' decisions on whether to adopt an EHR, and given the level of HITECH expenditures to date, there is significant policy value in assessing whether the HITECH incentives have actually had an impact on EHR adoption decisions among U.S. physicians in small, physician-owned practices. This study addresses this question by analyzing physicians' own views on the influence of the HITECH incentives as well as other potential considerations in their decision-making on whether to adopt an EHR.
Using data from a national survey of physicians, five composite scales were created from groups of survey items to reflect physician views on different potential facilitators and barriers for EHR adoption as of 2011, after the launch of the HITECH incentives program. Multinomial and binary logistic regression models were specified to test which of these physician-reported considerations have a significant relationship with EHR adoption status among 1043 physicians working in physician-owned practices with no more than 10 physicians.
Physicians' views on the importance of the HITECH financial incentives are strongly associated with EHR adoption during the first three years of the HITECH period (2010-2012). In the study's primary model, a one-point increase on a three-point scale for physician-reported influence of the HITECH financial incentives increases the relative risk of being in the process of adoption in 2011, compared to the risk of remaining a non-adopter, by a factor of 4.02 (p<0.001, 95% CI of 2.06-7.85). In a second model which excludes pre-HITECH adopters from the data, a one-point increase on the incentives scale increases the relative risk of having become a new EHR user in 2010 or 2011, compared to the risk of remaining a non-adopter, by a factor of 3.98 (p<0.01, 95% CI of 1.48-10.68) and also increases the relative risk of being in the process of adoption in 2011 by a factor of 5.73 (p<0.001, 95% CI of 2.57-12.76), compared to the risk of remaining a non-adopter in 2011. In contrast, a composite scale that reflects whether physicians viewed choosing a specific EHR vendor as challenging is not associated with adoption status.
This study's principal finding is that the HITECH financial incentives were influential in accelerating EHR adoption among small, physician-owned practices in the United States. A second finding is that physician decision-making on EHR adoption in the United States has not matched what would be predicted by the literature on network effects. The market's failure to converge on a dominant design in the absence of interoperability means it will be difficult to achieve widespread exchange of patients' clinical information among different health care provider organizations.
在美国,个体医生开办的小型诊所的医生采用电子健康记录(EHR)的速度比大型诊所或大型机构所有的诊所的医生要慢。2009年的《经济和临床健康的健康信息技术(HITECH)法案》包含了一些条款,旨在解决文献中提到的许多采用EHR的潜在障碍,其中包括一项财政激励计划,到2015年12月已向医生和其他专业人员支付了130亿美元。
鉴于可能影响医生是否采用EHR的因素众多,且考虑到迄今为止HITECH的支出水平,评估HITECH激励措施是否真的对美国个体医生开办的小型诊所的医生采用EHR的决策产生了影响具有重要的政策价值。本研究通过分析医生对HITECH激励措施的影响以及他们在决定是否采用EHR时的其他潜在考虑因素的自身看法来解决这个问题。
利用一项全国性医生调查的数据,从调查项目组中创建了五个综合量表,以反映截至2011年(HITECH激励计划启动后)医生对采用EHR的不同潜在促进因素和障碍的看法。指定多项和二元逻辑回归模型来测试这些医生报告的考虑因素中哪些与在不超过10名医生的个体医生开办的诊所工作的1043名医生的EHR采用状况有显著关系。
在HITECH时期的前三年(2010 - 2012年),医生对HITECH财政激励措施重要性的看法与EHR采用密切相关。在该研究的主要模型中,医生报告的HITECH财政激励措施影响的三分制量表上增加一分,与2011年仍未采用EHR的风险相比,采用过程中的相对风险增加4.02倍(p<0.001,95%置信区间为2.06 - 7.85)。在第二个模型中,数据排除了HITECH之前就采用的医生,激励措施量表上增加一分,与仍未采用EHR的风险相比,在2010年或2011年成为新的EHR用户的相对风险增加3.98倍(p<0.01,95%置信区间为1.48 - 10.68),并且与2011年仍未采用EHR的风险相比,2011年采用过程中的相对风险增加5.73倍(p<0.001,95%置信区间为2.57 - 12.76)。相比之下,一个反映医生是否认为选择特定的EHR供应商具有挑战性的综合量表与采用状况无关。
本研究的主要发现是,HITECH财政激励措施对加速美国个体医生开办的小型诊所采用EHR有影响。第二个发现是,美国医生在EHR采用方面的决策与网络效应文献所预测的情况不符。在缺乏互操作性的情况下,市场未能趋同于主导设计意味着难以在不同的医疗服务提供机构之间广泛交换患者的临床信息。
