Objective: The aim of this study was to explore the relationship between hospital characteristics and certified electronic health record (EHR) adoption in psychiatric hospitals in the US.
Methods: Data were drawn from the American Hospital Association Annual Survey Database and the Centers for Medicare and Medicaid Services Hospital Compare data sets in 2016. Binary logistic regression analysis and χ 2 tests were performed to examine the relationship between certified EHR adoption and hospital characteristics.
Results: Of 1,059 psychiatric hospitals in the US, 502 (47.4%) have adopted certified EHR technology. Large hospitals (OR 2.29, 95% CI 1.52– 3.44; p< 0.001), not-for-profit hospitals (OR 1.74, 95% CI 1.22– 2.49; p=0.008), and hospitals participating in a network (OR 1.78, 95% CI 1.34– 2.37; p< 0.001) were more likely to adopt certified EHRs. Hospitals in the northeast were less likely to implement certified EHRs compared to other regions. However, there was no significant association found between EHR utilization and system affiliation, urban location, teaching status, or participation of health-maintenance organizations and preferred provider organizations.
Conclusion: The study results suggested variations in EHR adoption according to hospital location, size, ownership, and network participation. This study fills a gap in previous work on certified EHR adoption that focused exclusively on general hospitals, but overlooked psychiatric hospitals. Future policies designed to influence the implementation of certified EHRs should take into consideration how hospital size, ownership, and network-affiliation status affect certified EHR adoption among psychiatric hospitals.

Unprecedented progress has been made in the utilization of certified electronic health records (EHRs) in US health settings, especially since the implementation of EHR incentive programs authorized by the Health Information Technology for Economic and Clinical Health Act in 2009,1 which have demonstrated substantial influences on the health industry.2–4 According to published studies, positive impacts of EHR utilization can be found on therapeutic communications,5,6 hospital readmission,7 adverse drug events,8 and psychiatrist–patient relationships,9–11 as well as other quality measures12–14 based on psychiatric patient or practitioner level. Despite these significant benefits, psychiatric hospitals are still ineligible for the financial incentive programs, and see much lower rates of EHR adoption15,16 than other hospitals. In 2015, only 15% of psychiatric hospitals adopted at least a basic EHR system produced by different vendors, while >80%of general hospitals did.17 Lag in certified EHR adoption among psychiatric hospitals might not only limit quality improvement of psychiatric care but also stymie efforts to achieve targeted benefits, such as interoperability, across the health-care continuum.16,18 It is thus crucial to explore the reasons for less adoption of certified EHRs among psychiatric hospitals.
A body of studies have addressed concerns about factors associated with the adoption of EHRs among general hospitals, nursing homes,19,20 office settings,21 cancer hospitals,22 critical-access hospitals,23 obstetrician/gynecologists,24 and ophthalmologists.25 Commonly included factors are initial cost of implementing a system,19,20,23,26–31 maintenance/ongoing costs,19,27,30,32 financial incentives,20,23,24,33 technical support,19,20,23,26,28,30 privacy concerns,19,21 perception of hospital staff,24,28,31–34 and workload/workflow change.20,23,24,26,30,33 Factors concerning facility characteristics have also been mentioned, such as practice setting,35 teaching status,36 system affiliation,37–39 location,22,35,36,40,41 ownership,39 and hospital size.30,37,39,40
However, psychiatric hospitals have not yet been specifically examined. Furthermore, due to the stress on confidentiality of psychiatric records and the special reliance on information for psychiatric diagnosis and treatment, the findings of previous works in nonpsychiatric hospitals may not apply equally to psychiatric hospitals.11,42 Exploring the relationship between hospital characteristics and certified EHR adoption in psychiatric hospitals may be helpful inbetter understanding factors that facilitate or impede certified EHR adoption, which hopefully will have positive influences on future policies of certified EHR adoption among psychiatric facilities. The purpose of this study was to examine the association between hospital characteristics and adoption of EHRs in psychiatric hospitals.
This study was a cross-sectional, secondary analysis based on data from two open and freely available primary databases: the American Hospital Association Annual Survey Database and the Centers for Medicare and Medicaid Services Hospital Compare data sets. The Annual Survey Database provided hospital characteristics information for 6,251 hospitals, including teaching status, bed numbers, location, ownership, and system affiliation. The Hospital Compare datasets provided data for 1,655 psychiatric hospitals on the adoption of certified EHRs from the Inpatient Psychiatric Facility Quality Reporting (IPFQR) program in 2016. Using Medicare identification numbers, data from those two sources were merged into one data set, and 596 hospitals were excluded because of missing data. The current study included 1,059 psychiatric hospitals. Because the information was anonymous and no personal information collected, this study was exempt from requirement for institutional review board approval.
Certified EHR Adoption and Cohorts
In the IPFQR program, there was a structural measure evaluating the degree to which hospitals adopted certified EHRs in health services. Hospitals were required to attest to one of three statements that best represented their highest level of adoption of EHRs: certified EHR technology is employed most commonly to exchange health information at times of transitions in care, uncertified EHR technology is used most commonly to transfer health information at times of transitions in care, and paper or other form (eg, email) is the most common approach to conduct information exchange not involving the transfer of health information using EHR technology at times of transitions in care. Two groups were categorized to these hospitals based on their EHR-adoption status. Psychiatric hospitals choosing the first statement were defined as hospitals with certified EHRs, whereas those responding with “uncertified EHRs” or “paper or other form” were categorized as hospitals with uncertified EHRs.
Hospitals were classified based on their bed numbers (small, <200 beds; medium, 200–400 beds; large, ≥400 beds), system affiliation (no/yes), teaching status (nonteaching/teaching), location (urban/rural), and region (northeast, south, west, midwest). Hospital ownership was classified as government, non-government, nonprofit, or for profit. Additional factors used for this study were network-affiliation status (no/yes), health-maintenance organization (HMO) participation (no/yes), and preferred provider organization (PPO) participation (no/yes). "Network" here refers to a group of hospitals, physicians, other providers, insurers, and/or community agencies that voluntarily work together to coordinate and deliver health services. Participation of HMOs/PPOs means having a formal written contract with an HMO or PPO.
Descriptive statistics were derived for hospital characteristics to report frequencies and percentages for each categorical variable, and χ2-tests were employed to examine bivariate associations between certified EHR-adoption and hospital characteristics among psychiatric hospitals. Correlation analyses (Pearson’s R) were derived among EHR-adoption and hospital characteristics. To determine independent associations, binary logistic regression analysis was conducted. All p-values were two-tailed and p<0.05 considered statistically significant. Data analyses were conducted using SPSSversion 24.0.
Hospital characteristics, represented by certified EHR-adoption status, are summarized in Table 1. Of the 1,059 psychiatric hospitals in the US included, 502 (47.4%) had adopted certified EHR technology. The majority of these hospitals were system-affiliated (66.4%) and located in rural areas (78.9%). Slightly more than half were non-government and nonprofit entities (57.6%) and 57.5% teaching hospitals. In addition, hospitals with <200 beds accounted for 48.5%.
Table 1 Psychiatric hospital characteristics (n=1,059)
On univariate analysis, psychiatric hospitals with certified EHRs were more likely to be larger (62.2% vs 41.8%, p<0.001), system-affiliated (70.5% vs 62.7%, p=0.007), not-for-profit (70.3% vs 46.1%, p<0.001), and teaching hospitals (66.3% vs 49.6%, p<0.001) than those with uncertified EHRs. Moreover, compared to hospitals not using certified EHRs, those using certified EHRs were also more likely to be a member of a network (52.6% vs 30.5%, p<0.001), HMO (82.7% vs 66.4%, p<0.001), and PPO (87.8% vs 70.7%, p<0.001). Furthermore, there was an association between hospital region and certified EHR adoption, while no significant relationship was found between urban/rural location and certified EHR utilization. In addition, results from Pearson's correlation analysis showed there was an association between certified EHR implementation and most of the aforementioned variables, excluding urban location and region (Appendix 1).
Binary logistic regression was conducted to explore independent associations between hospital characteristics and certified EHR adoption (Table 2). The logistic regression model was statistically significant (χ2=175.71, p<0.001) and explained 20.4% (Nagelkerke R2) of the variation in the outcome variable. Four variables in this model were significant at the p<0.05 level. Consistently with results from univariate analysis, large hospitals (OR 2.29, 95% CI 1.52–3.44; p<0.001), not-for-profit hospitals (OR 1.74, 95% CI 1.22–2.49; p=0.008), and thoseaffiliated with a network (OR 1.78, 95% CI 1.34–2.37; p<0.001) were more likely to adopt certified EHRs. Hospitals in the Northeast region were less likely to implement certified EHRs compared to the midwest (OR 1.96, 95% CI 1.35–2.84; p<0.001), south (OR 2.49, 95% CI 1.67–3.72; p<0.001), or west (OR 2.88, 95% CI 1.77–4.66; p<0.001). However, no significant association was found between certified EHR utilization and system affiliation, urban location, teaching status, and participation in HMOs/PPOs.
Table 2 Multivariate associations between certified EHR adoption and hospital characteristics among psychiatric hospitals (n=1,059)
Despite the large number of studies demonstrating how environmental factors influence adoption of certified EHRs among general hospitals, no study has specifically examined the impact ofhospital characteristics on certified EHR utilization in psychiatric hospitals. This study focused on psychiatric hospitals, with their special structures and unique challenges, and the results added specific understanding of the relationship between hospital characteristics and certified EHR implementation. The overall findings of this study showed that hospital characteristics played an important role in certified EHR adoption for psychiatric facilities, which echoes previous studies among general hospitals. Hospital characteristics, including region of hospital, bed numbers, ownership, and network participation, were significant predictors of certified EHR adoption. These findings have practical implications for policy-makers and hospital administrators who are tasked with strategy development for certified EHR adoption in psychiatric settings.
First, our findings suggest that the relationship of a hospital with a health network/system is associated with the adoption of certified EHRs in psychiatric hospitals. Specifically, psychiatric hospitals without involvement in a health network were less likely to use certified EHRs. Independent hospitals that have not formed a coalition or joined a health system may not have access to the benefits of economies of scale. As a multientity network/system, EHR networks can increase the value of individual EHR investment by minimizing infrastructure redundancy, employing bargaining power, and drawing upon operational and technical efficiencies.43
Second, hospital bed numbers were also found to be a predictor of certified EHR adoption, confirming prior findings.39,40 Large hospitals were more likely to implement certified EHRs, which require significant investment in hardware and software. Small hospitals are more challenged in terms of financial or human resources available to set up or run certified EHRs, which is consistent with prior findings that cost is a great barrier to certified EHR implementation.31,36,40 Requirements for providing quality of care, supporting routine operations, and renovating facilities may be much more pressing than investment in certified EHRs. On the contrary, large, revenue-rich hospitals with have the flexible capital to purchase EHRs. Therefore, it may be more challenging to promote the meaningful use of EHRs in small psychiatric facilities.
Third, the empirical findings of this study show that not-for-profit psychiatric hospitals were more likely to use EHRs than for-profit ones. Psychiatric hospitals that are ineligible for Health Information for Technological and Clinical Health incentives face the challenge of initial investment to implement certified EHRs. As costs of providing care are steadily increasing, additional investments in certified EHRs may not be a priority among for-profit hospitals. It might also be possible that for-profit psychiatric hospitals have calculated that the implementation cost of certified EHRs exceeds their potential benefits. Policy-makers should draw attention to and address hospitals’ concerns for return on investment, especially for for-profit psychiatric hospitals.
Moreover, this study suggests that certified EHR adoption in psychiatric hospitals was related to geographic location, which potentially indicates that market-level factors may influence psychiatric hospitals' decisions on adoption of health-information technology. Those factors include market competition,22,41,44 number of ophthalmologists per capita,41 managed care penetration,22,41 HMO penetration,45 munificence (availability of critical resources in the environment),44–46 population >65 years of age,22 and unemployment and poverty rates.44–46 Further studies are needed to explore associations among these multiple factors, and specifically on how geographic factors influence adoption of certified EHRs among psychiatric hospitals. Additionally, in the regression model, even though teaching status, system affiliation, and urban location were not significant predictors of certified EHR adoption in psychiatric hospitals, they were included in the analysis as control variables to reduce the chance of confounding influencs on hospitals’ behavior. It appears that certified EHR adoption in psychiatric hospitals is not very responsive to urban location or teaching status, which is inconsistent with previous findings.47,48
This study has several limitations worth noting. Findings in this cross-sectional research design are unable to indicate causal associations and can only be interpreted as associations. Another limitation of this work is the approach to identify psychiatric hospitals that have adopted certified EHRs. EHRs from different vendors or manufacturers varied in features and functions. Even though the IPFQR program clearly defined a structural measure to evaluate the degree to which hospitals adopted certified EHRs in health services, the responses may contain reporting bias. In addition, cases with missing values for some variables were excluded from the model in the current study, which imposes a potential selection bias on the findings. With available data, comparison studies between general and psychiatric hospitals should be conducted to explore the particular effect of organizational factors on EHR adoption among psychiatric hospitals.
Hospital characteristics, such as regional location, bed numbers, ownership, and network participation, were associated with certified EHR adoption in psychiatric hospitals in the US. This research fills a gap in previous work focusing on general hospitals, but largely overlooking psychiatric hospitals. To inform these adoption decisions, this study provides evidence on hospital features that are associated with adoption of certified EHRs for psychiatric hospitals. Future policies targeting implementation of certified EHRs should take into consideration economies of scale and return on investment of psychiatric-facility network affiliation and ownership status. More efforts may be needed to promote small psychiatric hospitals to utilize EHRs. Further research is necessary to explore factors that influence certified EHR adoption among psychiatric hospitals, such as market-level environmental factors. In addition, studies applying conceptual and theoretical frameworks to explore such variables as interactions among technological, organizational, and environmental factors should be undertaken.
