The impact of interoperability of electronic health records on ambulatory physician practices: a discrete-event simulation study

Background The effect of health information technology (HIT) on efficiency and workload among clinical and nonclinical staff has been debated, with conflicting evidence about whether electronic health records (EHRs) increase or decrease effort. None of this paper to date, however, examines the effect of interoperability quantitatively using discrete event simulation techniques.Objective To estimate the impact of EHR systems with various levels of interoperability on day-to-day tasks and operations of ambulatory physician offices.Methods Interviews and observations were used to collect workflow data from 12 adult primary and specialty practices. A discrete event simulation model was constructed to represent patient flows and clinical and administrative tasks of physicians and staff members.Results High levels of EHR interoperability were associated with reduced time spent by providers on four tasks: preparing lab reports, requesting lab orders, prescribing medications, and writing referrals. The implementation of an EHR was associated with less time spent by administrators but more time spent by physicians, compared with time spent at paper-based practices. In addition, the presence of EHRs and of interoperability did not significantly affect the time usage of registered nurses or the total visit time and waiting time of patients.Conclusion This paper suggests that the impact of using HIT on clinical and nonclinical staff work efficiency varies, however, overall it appears to improve time efficiency more for administrators than for physicians and nurses

Medical and nursing staff highly value clinical pharmacists in the emergency department

Despite the potential impact that emergency pharmacist (EPh) programmes could have on medication safety and quality of care in the emergency department (ED), very few programmes exist. This descriptive survey study aimed to assess staff perceptions of an EPh programme. A random sample of medical and nursing staff in an academic medical centre ED with a dedicated EPh programme received a 26‐item survey (82% return rate). 99% of respondents felt the EPh improves quality of care, 96% feel they are an integral part of the team, and 93% had consulted the EPh at least a few times during their last five shifts. Staff felt that the EPh should be available for consults, attend resuscitations, and check orders. This study reinforced the value of many specific duties of the EPh programme and found that doctors and nurses overwhelmingly favour the presence of an EPh in the ED, frequently seek their advice, and feel they improve quality of care. Staff acceptance is clearly not a barrier to implementation of this programme

A Usability and Safety Analysis of Electronic Health Records: A Multi-center Study

To characterize the variability in usability and safety of EHRs from two vendors across four healthcare systems (2 Epic and 2 Cerner). Twelve to 15 emergency medicine physicians participated from each site and completed six clinical scenarios. Keystroke, mouse click, and video data were collected. From the six scenarios, two diagnostic imaging, laboratory, and medication tasks were analyzed. There was wide variability in task completion time, clicks, and error rates. For certain tasks, there were an average of a nine-fold difference in time and eightfold difference in clicks. Error rates varied by task (X-ray 16.7% to 25%, MRI: 0 to 10%, Lactate: 0% to 14.3%, Tylenol: 0 to 30%; Taper: 16.7% to 50%). The variability in time, clicks, and error rates highlights the need for improved implementation optimization. EHR implementation, in addition to vendor design and development, is critical to usable and safe products
