E-prescribing: a focused review and new approach to addressing safety in pharmacies and primary care

A Taxonomy for Health Information Systems

The health sector is highly digitized, which is enabling the collection of vast quantities of electronic data about health and well-being. These data are collected by a diverse array of information and communication technologies, including systems used by health care organizations, consumer and community sources such as information collected on the web, and passively collected data from technologies such as wearables and devices. Understanding the breadth of IT that collect these data and how it can be actioned is a challenge for the significant portion of the digital health workforce that interact with health data as part of their duties but are not for informatics experts. This viewpoint aims to present a taxonomy categorizing common information and communication technologies that collect electronic data. An initial classification of key information systems collecting electronic health data was undertaken via a rapid review of the literature. Subsequently, a purposeful search of the scholarly and gray literature was undertaken to extract key information about the systems within each category to generate definitions of the systems and describe the strengths and limitations of these systems.

Stakeholder perspectives on electronic prescribing in primary care: A scoping review

BACKGROUND

Electronic prescribing (e-prescribing) provides a convenient, efficient, paperless mechanism for the legal transfer of prescriptions between service users, prescribers, and dispensers. There have been advances in e-prescribing processes and increased uptake of e-prescribing globally, in recent years.

OBJECTIVE

To explore stakeholder perspectives on e-prescribing in primary care settings.

METHODS

A scoping review was conducted by systematically searching Medline, EMBASE, Scopus, and International Pharmaceutical Abstracts databases, using the key concepts "primary care", "e-prescribing", and "perspectives". Publications were selected by screening for eligibility against inclusion and exclusion criteria, whereby any publication written in English exploring e-prescribing in primary care settings from the perspective(s) of at least one type of stakeholder was eligible for inclusion. Following a systematic screening process, relevant data were extracted, collated, and synthesized.

RESULTS

Two thousand publications were identified and systematically screened, rendering 44 publications (e.g., primary research articles, abstracts) eligible for inclusion in this review. Most publications reported on studies conducted in the USA, the UK, and Europe and explored the views of pharmacists, pharmacy technicians, and pharmacy staff. Barriers to e-prescribing included system design and technical issues, lack of adequate training and communication issues between stakeholders. Enablers for e-prescribing included time savings, convenience, and increased legibility of prescriptions.

CONCLUSIONS

This review highlights many benefits of e-prescribing such as time efficiency, convenience, increased legibility, and less mishandling. Despite this, key barriers to e-prescribing within primary care settings were also recognized, including system design, technical issues, and lack of adequate training. As such, forcing functions, prescription tracking technologies, and better training have been identified as potential ways to address these barriers. While some negative experiences were reported, stakeholders were generally satisfied and had positive experiences with e-prescribing.

Electronic transmission of prescriptions in primary care: transformation, timing and teamwork

INTRODUCTION During the coronavirus disease 2019 (COVID-19) pandemic lockdown in New Zealand in March 2020, there was a rapid shift to virtual consultations in primary care. This change was supported by system adjustments to enable electronic transmission of prescriptions without a handwritten signature if they met certain security criteria. International research suggests potential for unintended consequences with such changes, so it is important to understand the effect on professional practice in New Zealand general practice and community pharmacy. AIM The purpose of this study was to undertake a preliminary exploration of the experiences of New Zealand general practitioners and community pharmacists when prescriptions are transmitted electronically directly from prescriber to pharmacy. METHODS Semi-structured interviews with a purposive sample of four pharmacists and four general practitioners gathered qualitative data about their experiences of the shift to electronic transmission of prescriptions. Participants' perceptions of effect on professional workflow, interprofessional interactions between general practitioners and pharmacists, and interactions with patients were explored. Interviews were audio-recorded, and the data analysed thematically using an inductive approach. RESULTS Four themes were identified: workflow transformation; mixed impact on interactions with patients; juggling timing and expectations; and new avenues for interprofessional communication (with some cul-de-sacs). DISCUSSION Both general practitioners and pharmacists experienced transformational changes to workflow. This was positive for general practitioners due to saved time and increased work flexibility. Pharmacists noted potential benefits but also some challenges. To fully reap teamwork benefits, more work is needed on managing the timing issues and patient expectations, and to refine the new modes of communication between health-care practitioners.

Implementation of a shared medication list in primary care - a controlled pre-post study of medication discrepancies

Background

Access to medicines information is important when treating patients, yet discrepancies in medication records are common. Many countries are developing shared medication lists across health care providers. These systems can improve information sharing, but little is known about how they affect the need for medication reconciliation. The aim of this study was to investigate whether an electronically Shared Medication List (eSML) reduced discrepancies between medication lists in primary care.

Methods

In 2018, eSML was tested for patients in home care who received multidose drug dispensing (MDD) in Oslo, Norway. We followed this transition from the current paper-based medication list to an eSML. Medication lists from the GP, home care service and community pharmacy were compared 3 months before the implementation and 18 months after. MDD patients in a neighbouring district in Oslo served as a control group.

Results

One hundred eighty-nine patients were included (100 intervention; 89 control). Discrepancies were reduced from 389 to 122 (p <  0.001) in the intervention group, and from 521 to 503 in the control group (p = 0.734). After the implementation, the share of mutual prescription items increased from 77 to 94%. Missing prescriptions for psycholeptics, analgesics and dietary supplements was reduced the most.

Conclusions

The eSML greatly decreases discrepancies between the GP, home care and pharmacy medication lists, but does not eliminate the need for medication reconciliation.

Human factors and ergonomics methods for pharmacy research and clinical practice

BACKGROUND

Human factors and ergonomics (HFE) is a scientific and practical human-centered discipline that studies and improves human performance in sociotechnical systems. HFE in pharmacy promotes the human-centered design of systems to support individuals and teams performing medication-related work.

OBJECTIVE

To review select HFE methods well suited to address pharmacy challenges, with examples of their application in pharmacy.

METHODS

We define the scope of HFE methods in pharmacy as applications to pharmacy settings, such as inpatient or community pharmacies, as well as medication-related phenomena such as medication safety, adherence, or deprescribing. We identify and present seven categories of HFE methods suited to widespread use for pharmacy research and clinical practice.

RESULTS

Categories of HFE methods applicable to pharmacy include work system analysis; task analysis; workload assessment; medication safety and error analysis; user-centered and participatory design; usability evaluation; and physical ergonomics. HFE methods are used in three broad phases of human-centered design and evaluation: study; design; and evaluation. The most robust applications of HFE methods involve the combination of HFE methods across all three phases. Two cases illustrate such a comprehensive application of HFE: one case of medication package, label, and information design and a second case of human-centered design of a digital decision aid for medication safety.

CONCLUSIONS

Pharmacy, including the places where pharmacy professionals work and the multistep process of medication use across people and settings, can benefit from HFE. This is because pharmacy is a human-centered sociotechnical system with an existing tradition of studying and analyzing the present state, designing solutions to problems, and evaluating those solutions in laboratory or practice settings. We conclude by addressing common concerns about the implementation of HFE methods and urge the adoption of HFE methods in pharmacy.

Digital Health in Physicians' and Pharmacists' Office: A Comparative Study of e-Prescription Systems' Architecture and Digital Security in Eight Countries

e-Prescription systems are key components and drivers of digital health. They can enhance the safety of the patients, and are gaining popularity in health care systems around the world. Yet, there is little knowledge on comparative international analysis of e-Prescription systems' architecture and digital security. We report, in this study, original findings from a comparative analysis of the e-Prescription systems in eight different countries, namely, Canada, United States, United Kingdom, Australia, Spain, Japan, Sweden, and Denmark. We surveyed the databases related to pharmacies, eHealth, e-Prescriptions, and related digital health websites for each country, and their system architectures. We also compared the digital security and privacy protocols in place within and across these digital systems. We evaluated the systems' authentication protocols used by pharmacies to verify patients' identities during the medication dispensing process. Furthermore, we examined the supporting systems/services used to manage patients' medication histories and enhance patients' medication safety. Taken together, we report, in this study, original comparative findings on the limitations and challenges of the surveyed systems as well as in adopting e-Prescription systems. While the present study was conducted before the onset of COVID-19, e-Prescription systems have become highly relevant during the current pandemic and hence, a deeper understanding of the country systems' architecture and digital security that can help design effective strategies against the pandemic. e-Prescription systems can help reduce physical contact and the risk of exposure to the virus, as well as the wait times in pharmacies, thus enhancing patient safety and improving planetary health.

Implementation fidelity of patient-centered prescription label to promote opioid safe use

PURPOSE

Patient-centered labels may improve safe medication use, but implementation challenges limit use. We assessed implementation of a patient-centered "PRN" (as needed) label entitled "Take-Wait-Stop" (TWS) with three deconstructed steps replacing traditional wording.

METHODS

As part of a larger investigation, patients received TWS prescriptions (eg, Take: 1 pill if you have pain; Wait: at least 4 h before taking again; Stop: do not take more than 6 pills in 24 h). Prescriptions labels recorded at follow-up were classified into three categories: (1) one-step wording (Take 1 pill every 4 h [without daily limits]), (2) two-step wording (Take 1 pill every 4 h; do not exceed 6 pills/day), and (3) three-step wording. There were three subtypes of three-step wording: (3a) three-step, not TWS (three deconstructed steps, not necessarily TWS wording), (3b) TWS format, employing three steps with leading verbs, but "with additions or replacements" (eg, replaced "do not take" with "do not exceed"), and (3c) verbatim TWS.

RESULTS

Two hundred eleven participants completed follow-up. Mean age was 44.3 years (SD 14.3); 44% were male. One-step bottles represented 12% (n = 25) of the sample, whereas 26% (n = 55) had two-step wording. The majority (44%, n = 93) had three-deconstructed steps, not TWS (3a); 16% (n = 34) retained TWS structure, but not verbatim (3b). Only 2% (n = 4) displayed verbatim TWS wording (3c). All category three labels (utilizing deconstructed instructions) were considered adequate implementation (62%).

CONCLUSIONS

Exact intervention adherence was not achieved in the majority of cases, limiting impact. Nonetheless, community pharmacies were responsive to new instructions, but higher implementation reliability requires additional supports.

A Quantitative and Qualitative Analysis of Electronic Prescribing Incidents Reported by Community Pharmacists

BACKGROUND

Electronic prescribing (e-prescribing) technology was introduced as an alternative to handwritten prescriptions allowing health care professionals to send prescriptions directly to pharmacies. While the technology has many advantages, such as improving pharmacy workflow and reducing medication errors, some limitations have been realized.

OBJECTIVE

The objective of this study was to examine the frequency, type, and contributing factors of e-prescribing quality-related incidents reported to two national error-reporting databases in the United States.

METHODS

This was a retrospective analysis of voluntarily reports of e-prescribing quality-related incidents. A quantitative and qualitative analysis was conducted of incidents reported between 2011 and 2015 to the Pharmacy Quality Commitment (PQC) and the Pharmacy Provider e-prescribing Experience Reporting Portal (PEER) databases. For the qualitative analysis, events were combined from the PQC and PEER portal and a 10% random sample of events were analyzed.

RESULTS

A total of 589 events were reported to the PEER Portal. Of these, problems with patient directions were the most frequent incident type (n = 210) of which 10% (n = 21) reached the patient. Quantity selection (n = 158) and drug selection (n = 96) were the next most frequently reported events, 20% of which reached the patient. The PQC system received 550 reports. The most frequent event type reported to this system was incorrect directions (23.3%, n = 128) followed by incorrect prescriber (17%), incorrect drug (15%), and incorrect strength (12%). The most common theme in the qualitative analysis was a perceived increased likelihood of patient receiving incorrect drug therapy due to e-prescribing. Another theme identified included confusion and frustration of pharmacy personnel as result of e-prescription quality-related events.

CONCLUSION

The use of qualitative and quantitative incident data revealed that patient directions and quantity selection were the most common quality issues with e-prescribing. In turn, this may increase the likelihood of patients receiving incorrect drug therapy.

Patient Perceptions of Electronic Prescriptions in Belgium: An Exploratory Policy Analysis

In today’s world, digitalization and automation are ubiquitous and different countries have different strategies for implementing information technology in health care. In Belgium, these plans include the dematerialization of prescriptions, following the implementation of a system of electronic prescribing. In the light of these changes, we studied the attitudes of patients toward a paperless prescription. We collected the opinions of 273 patients by survey. Older people, or people with more complex medical needs, expressed a clear desire to keep receiving a paper version of the prescription. Younger people foresaw practical advantages, and expressed a willingness to buy prescription-only medicines online. Knowledge about the planned changes was, however, limited. Privacy and autonomy issues were expressed by a large fraction of people. The problem of what happens when a third person wants to pick up medicines for a patient, a frequent occurrence, was often mentioned. We conclude that, at present, patients have inadequate knowledge and understanding about the planned changes. In light of these considerations and the recent technical problems encountered by the system, we feel that an updated risk/benefit analysis of the planned policy is urgently needed.

Assessing the Physicians' Acceptance of E-Prescribing in a Developing Country

This article describes how physicians in developing countries spend much time and effort in handling manual prescriptions, which can be easily reduced with the help of online technology. Although different theoretical models for technology acceptance have been thoroughly explored, there is as yet sparse literature regarding its use in the context of healthcare in developing countries, especially with innovative models. To this end, this article uses an integrative model of Unified Theory of Acceptance and Use of Technology (UTAUT) extended by perceived credibility to better understand the acceptance of e-prescribing among physicians in a developing Asian country. In addition, the article uses perceived organizational support as a moderator between behavioral intentions and usage of technology. Using a survey method, the article collects data from 295 physicians in the capital city of Pakistan and analyzes the data through structural equation modeling (SEM) to evaluate relationships among the identified constructs. The authors' results supply empirical evidence that performance expectancy, effort expectancy, facilitating conditions, social influence, and perceived credibility all have a positive and significant impact on physicians' behavioral intentions to adopt e-prescribing. The article also concludes that the higher the perceived organizational support, the higher the use of e-prescribing. The study enriches theory and practice by giving implications for both academicians and practitioners.

Factors Affecting Rural Patients' Primary Compliance with e-Prescription: A Developing Country Perspective

Background:The electronic prescription system has emerged to reduce the ambiguity and misunderstanding associated with handwritten prescriptions. The opportunities and challenges of e-prescription system, its impact on reducing medication error, and improving patient's safety have been widely studied. However, not enough studies were conducted to explore and quantify the factors that affect rural patients' compliance with e-prescription, especially from the perspective of Asian developing countries where most of the world's population resides.

Objective:The objective of this study is to explore and assess the factors that affect rural patients' primary compliance with e-prescription in Bangladesh.

Methods:Data were collected from 95 randomly selected rural patients who received e-prescription through a field survey with a structured questionnaire from Bheramara subdistrict, Bangladesh, during June and July 2016. Logistic regression analysis was performed to test the research hypotheses.

Results:The study found patients' gender as the most significantly influential factor (regression coefficient [Coef.] = 2.02, odds ratio [OR] = 7.51, p < 0.05) followed by visiting frequency (Coef. = 0.99, OR = 2.70, p < 0.05); education (Coef. = 0.92, OR = 2.51, p < 0.05); and distance to healthcare facility (Coef. = 0.82, OR = 2.26, p < 0.01). However, patients' age, monthly family expenditure, and use of cell phone were found insignificant. The model explains 59.40% deviance (R² = 0.5940) in the response variable with its constructs. And the “Hosmer–Lemeshow” goodness-of-fit score (0.99) is also above the standard threshold (0.05), which indicates the data fit well with the model.

Conclusions:The findings of this study are expected to be helpful for e-health service providers to gain a better understanding of the factors that influence their patients to comply with e-prescriptions.

Factors Influencing the Total Inpatient Pharmacy Cost at a Tertiary Hospital in Malaysia: A Retrospective Study

The steady growth of pharmaceutical expenditures is a major concern for health policy makers and health care managers in Malaysia. Our study examined the factors affecting the total inpatient pharmacy cost (TINPC) at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC). In this retrospective study, we used 2011 administration electronic prescriptions records and casemix databases at UKMMC to examine the impact of sociodemographic, diagnostic, and drug variables on the TINPC. Bivariate and multivariate analyses of the factors associated with TINPC were conducted. The mean inpatient pharmacy cost per patient was USD 102.07 (SD = 24.76). In the multivariate analysis, length of stay (LOS; B = 0.349, P < .0005) and severity level III (B = 0.253, P < .0005) were the primary factors affecting the TINPC. For each day increase in the LOS and each increase of a case of severity level III, there was an increase of approximately USD 11.97 and USD 171.53 in the TINPC per year, respectively. Moreover, the number of prescribed items of drugs and supplies was positively associated with the TINPC (B = 0.081, P < .0005). Gender appears to have affected the TINPC; male patients seem to be associated with a higher TINPC than females (mean = 139.55, 95% confidence interval [CI]: 112.97-166.13, P < .001). Surgical procedures were associated with higher cost than medical cases (mean = 87.93, 95% CI: 61.00-114.85, P < .001). Malay (MYR 242.02, SD = 65.37) and Chinese (MYR 214.66, SD = 27.99) ethnicities contributed to a lower TINPC compared with Indian (MYR 613.93, SD = 98.41) and other ethnicities (MYR 578.47, SD = 144.51). A longer hospitalization period accompanied by major complications and comorbidities had the greatest influence on the TINPC.

Community health integration through pharmacy process and ergonomics redesign (CHIPPER)

As the expansion and utilisation of community pharmacy systems increases, so does the risk for an adverse drug event to occur. In attempts to mitigate this risk, many community pharmacies implement health information technology (IT); however, there are challenges in integrating the wider systems components necessary for a successful implementation with minimal unintended consequences. The purpose of this paper is to introduce a Community Health Integration through Pharmacy Process and Ergonomics Redesign (CHIPPER) framework, which explores the multiple angles of health IT integration to support medication delivery processes in community pharmacy systems. Specifically, CHIPPER identifies the information flows that occur between different parts of the system (initiation, upstream, midstream and downstream) with varying end-users and tasks related to medication delivery processes. In addition to the justification and presentation of the CHIPPER model, this paper reviews several broad applications for CHIPPER and presents two example studies that demonstrate the CHIPPER framework. Practitioner Summary: Most medication delivery in the US occurs through outpatient-based community pharmacy practice. Community pharmacies are challenged by inconsistent and incomplete information flow and technology integration between providers, pharmacy practitioners and patients. This paper presents a framework for improved healthcare systems engineering analysis of pharmacy practice, with case study examples.

e-Prescribing in the Acute Care Setting: Determining the Educational and Motivational Needs of Healthcare Providers

The study sought to determine the barriers to e-prescribing particular to the acute care setting, the educational and motivational needs of acute care providers, and the optimal process for incentive, education, and implementation of e-prescribing. A theoretically based survey instrument was adapted from previous work. Four domains were assessed: finesse, intent to use, perceived usefulness, and perceived ease of use. The survey was offered to a group of acute care providers. The educational and motivational needs of acute care providers are different from those in primary care. Perceived barriers centered on uncertain pharmacy hours, unconfirmed transmittal, and accidental transmission to wrong pharmacy. Healthcare providers with more self-assessed knowledge of e-prescribing are more likely to use e-prescribing. Providers with fewer years in practice seem to have greater knowledge of e-prescribing. Providing education and exposure to e-prescribing has the potential to decrease perception of barriers and increase perceived usefulness for acute care providers. Software redesign may be needed to remove barriers associated with uncertain pharmacy hours, controlled substance prescribing, transmittal confirmation, and bidirectional communication needs, thereby improving motivation to e-prescribe.

Quality and Safety in Health Care, Part IX: Computerized Provider Order Entry

One of the most important technologic advances to reduce medication errors is computerized provider order entry linked with clinical decision support. These systems also have the potential to improve the adherence of clinicians to best practices, decrease the turnaround time for laboratory tests and radiology examinations, speed transmission of prescriptions to the pharmacy, decrease medication costs, and increase the frequency of vaccinations.

Patient perceptions of e-prescribing and its impact on their relationships with providers: a qualitative analysis

OBJECTIVE

To describe patients' perceptions of electronic (e)-prescribing and its impact on patients' quality of care, interactions with prescribers and pharmacists, and engagement in health care overall, particularly in regard to medication use.

METHODS

Semistructured, one-on-one interviews with 12 patients.

RESULTS

Patients were generally unfamiliar with the functions of integrated e-prescribing systems and did not perceive that use of such technology affected their relationships with providers. Those respondents having positive perceptions of, and experiences with e-prescribing mostly cited convenience and improvements in safety and quality, while patients with negative e-prescribing perceptions and experiences primarily expressed concern about loss of control in the medication-use process, misdirected prescriptions, and reduced communication with prescribers and pharmacists.

CONCLUSION

Patients generally felt unaffected by the use of e-prescribing technology; however, there may be opportunities to better engage and educate patients, particularly at the point of prescribing.

The impacts of second generation e-prescribing usability on community pharmacists outcomes

BACKGROUND

The results from past studies about the effects of second-generation e-prescribing systems on community pharmacists' outcomes and practices are inconclusive, and the claims of effectiveness and efficiency of such systems have not been supported in all studies. There is a strong need to study the factors that lead to positive outcomes for the users of these systems.

OBJECTIVE

This paper intends to bridge the above gaps by empirically examining the impacts of user interface usability on the community pharmacists' outcomes.

METHODS

A quantitative survey research method was used and the data was collected from the community pharmacists, who use an e-prescribing system. Data from 152 questionnaires collected in a national survey were used to for the study. Partial Least Squares (PLS) path modeling was used to examine scale reliability, validity and hypotheses.

RESULTS

The scale was found to test well for reliability and validity. Examining the hypotheses illustrated that ease of use (P < 0.01, t = 5.79) and information quality (P < 0.01, t = 6.24) of an e-prescribing system improved pharmacists' outcomes (including communication, facilitation of care, reduction of workload and medical errors) while ease of use of the system was influenced by user interface consistency (P < 0.01, t = 7.35) and system error prevention (P < 0.01, t = 5.29).

CONCLUSION

To improve community pharmacists' outcomes and practices, the ease of use, information quality, consistency and error prevention features of e-prescribing systems should be improved. It was found that information quality had a stronger impact on the outcomes and hence improving the quality of the generated information would have higher impacts on users' outcomes.

Using a conflict conceptual framework to describe challenges to coordinated patient care from the physicians' and pharmacists' perspective

BACKGROUND

In an effort to increase cost-effectiveness of health care and reduce overall costs, patient-centered medical homes have been proposed to spur fundamental changes in the way primary care is delivered. One of the chief principles that describe a patient-centered medical home is that care is organized across all elements of the broader health care system, including community pharmacies.

OBJECTIVES

To identify and describe challenges derived from a conflict management framework to a physician-pharmacist approach to coordinating patient care.

METHODS

A descriptive, exploratory, non-experimental study was conducted in Wisconsin (U.S. State) from June to December, 2011. Data were collected through two rounds of face-to-face interviews with physicians and community pharmacists. The first round involved one-on-one interviews with pharmacists and physicians. The second round brought pharmacist-physician dyads together in an open-ended interview exploring issues raised in the first round. Content analysis was guided by a conflict management conceptual framework using NVivo 10 qualitative software.

RESULTS

A total of four major themes emerged from the conflict analysis of interviews that illustrate challenges to coordinated patient care: Scarce resources, technology design and usability, insurance constraints, and laws and policy governing patient care. The study findings indicate that both groups of health care professionals work within an environment of conflict and have to negotiate the challenges and strains that exist in the current health care system. Their need to work together, or interdependence, is primarily challenged by scarce resources and external interference.

CONCLUSIONS

Efforts to coordinate patient care through teams of inter-professional health care providers will be more successful if they acknowledge the inherent conflict that exists. Efforts should be made to provide an infrastructure for interdependence and to support interpersonal communication.
