The adoption of health information technology (HIT), such as electronic health records and clinical decision support systems, has transformed medicine and healthcare and will continue to do so, especially with the rise of new technologies like artificial intelligence (AI). HIT, which can be defined as “any automated or computerized system implemented to aid in the management of health information” [1], is supposed to reduce costs while improving the quality and effectiveness of healthcare [2, 3]. The implementation of HITs can have positive effects on patient outcomes, such as a reduction in adverse events and mortality; however, many studies have found non-significant or mixed results for their benefits [1, 4]. At the same time, the introduction of HITs into complex healthcare systems can be disruptive and might even lead to errors that can cause serious harm and death [3, 5]. So far, most studies have focused on HITs’ effects on practitioner performance and patient outcomes. However, it is also important to understand the effect HITs have on psychological and organizational variables that might influence users’ performance and patient outcomes in turn.
HITs can be cumbersome and frustrating to use [6, 7] and might result in an adverse condition called technostress [8]. Technostress has been defined as the “inability to adapt or cope with new computer technologies in a healthy manner” [9] and “an IT user’s experience of stress when using technologies” [8]. Technostress has been associated with several adverse organizational outcomes, such as lower productivity, reduced job performance, and increased turnover intention [8]. These negative consequences are influenced by two variables often studied as consequences of technostress: strain and job satisfaction. Scholars have argued that experiencing technostress can lead to psychological strain [10–12], which is a person’s response to the exposure to stressors [13]. Examples of techno-stressors are situations in which HITs force the user to work faster and longer or constantly adapt to new technology. However, not every person who is exposed to techno-stressors is affected in the same manner. Technology self-efficacy, which is a person’s perceived capability to successfully perform a technologically-related task [14], has been shown to influence the level of technostress a user experiences [15]. Therefore, technology self-efficacy might moderate the relationship between technostress and IT-related strain. People higher in technology self-efficacy experience lower levels of strain when exposed to techno-stressors and vice versa.
It is well established that higher levels of strain are associated with lower job satisfaction [16–18]. Therefore, healthcare workers’ job satisfaction might also be negatively impacted by the strain caused by exposure to techno-stressors when working with HITs, as has been previously shown in teleworkers [11]. Job satisfaction is the overall evaluative judgment a person has about their job [19] and is one of the most widely researched organizational variables. Previous studies have also investigated the direct effect of technostress on job satisfaction [8, 20–22]. Being exposed to more information than can be handled, having to keep up with rapidly changing and increasingly more complex technology, as well as constant connectivity can leave the user feeling frustrated and dissatisfied. According to one review, the stressor techno-overload, which is the technology’s tendency to force a person to work faster and longer, has been especially associated with lower job satisfaction [8].
The level of technostress experienced by a person can be influenced by individual factors, job-related factors, and technology characteristics. One important technology characteristic associated with technostress, which is also a common problem for health ITs, is poor usability [3, 5, 23, 24]. According to the ISO 9241-11:2018, usability is defined as “the extent to which a system, product or service can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use” [25]. Scholars have argued that the three usability features are especially important for technology users: usefulness, ease of use, and reliability [10]. While poor usability, which can create information overload, might cause higher levels of technostress, perceiving the technology as useful, easy to use, and reliable has been associated with lower levels of technostress [10]. Additionally, poor usability is a source of strain [26–28]. However, health ITs with good usability might reduce the user’s perceived strain because they are supposed to make task attainment as easy as possible and therefore decrease workload. Finally, the usability of technology in everyday use might also affect staff job satisfaction [22, 29, 30]. Users who must interact with poorly designed HITs are likely to be dissatisfied because they might experience workflow interruptions and increased workload. Per its definition, good usability should allow the user to achieve specified goals with satisfaction.
Both work-related strain and job satisfaction are crucial organizational variables. Previous research has identified numerous negative health consequences resulting from persistent work-related strain such as burnout, substance abuse, sleep disturbance, concentration deficits, and many others [31, 32]. Strain and these related outcomes can affect workers’ performance [12] and have been associated with medical errors [18, 33, 34]. Medical errors are defined as “an act of omission or commission in planning or execution that contributes or could contribute to an unintended result” [35] and include medication mistakes, wrong diagnoses, and avoidable delays in treatment, among others. Both directions of the relationship between strain and medical errors are plausible: On the one hand, the negative consequences of strain, such as concentration problems, might cause mistakes. On the other hand, realizing that a medical error has occurred might lead to even higher levels of strain. Medical errors are estimated to be among the leading causes of morbidity and mortality among patients [36–38] and therefore a substantial threat to patient safety. Hence, it is crucial to identify predictors for medical errors, especially factors that have received little attention so far, such as strain caused by the interaction with health IT.
Job satisfaction is another potential factor contributing to medical errors that has not been well-researched. What has been established is the association between job satisfaction and job performance [39, 40]. Again, there is evidence for both directions of the relationship: job satisfaction leading to better performance and the other way around. Additionally, low job satisfaction is commonly cited as one of the strongest predictors for counterproductive work behavior [41–43], which are deliberate and potentially harmful acts towards an organization or its stakeholders such as supervisors, clients, co-workers [44], and patients. Since both job performance and counterproductive work behavior are related to making mistakes, it might be speculated that there is a direct association between job satisfaction and medical errors.
Naturally, healthcare facilities try to prevent errors altogether to minimize risks and avoid negative consequences. However, realistically, medical errors can never be completely prevented. Error management is an approach aiming to reduce the negative outcomes of errors and increase long-term positive consequences such as learning, innovation, and resilience [45, 46]. An organization with a positive error management culture fosters communication about errors, knowledge sharing, and strategies to detect and effectively handle errors [45, 46]. In turn, an effective error management culture should lead to better performance [45] and reduce avoidable errors by applying lessons learned from previous mistakes to improve processes [secondary error prevention 45, 46]. A good error management culture might also have a positive effect on staff members’ job satisfaction because it should reduce their fear of being punished for causing and/or reporting errors [47].
The goal of the present study is to investigate the associations between HIT characteristics (usability and techno-stressors), healthcare workers’ IT-related strain, and job satisfaction. While strain and job satisfaction are important outcome variables themselves, we also want to test if they, combined with healthcare workers’ perceived error management culture, can help to explain self-reported medical errors. These insights might lead to a better understanding of why many studies did not find improvements in patient outcomes after the implementation of HITs. To test the proposed hypotheses (Fig. 1), a nation-wide survey among healthcare workers in German hospitals was conducted.
