Physicians' experiences using commercial e-prescribing systems

Challenges and advantages of electronic prescribing system: a survey study and thematic analysis

INTRODUCTION

Electronic prescribing (e-prescribing) systems can bring many advantages and challenges. This system has been launched in Iran for more than two years. This study aimed to investigate the challenges and advantages of the e-prescribing system from the point of view of physicians.

METHODS

In this survey study and thematic analysis, which was conducted in 2023, a researcher-made questionnaire was created based on the literature review and opinions of the research team members and provided to the physician. Quantitative data were analyzed using SPSS software, and qualitative data were analyzed using ATLAS.ti software. Rank and point biserial, Kendall's tau b, and Phi were used to investigate the correlation between variables.

RESULTS

Eighty-four physicians participated in this study, and 71.4% preferred to use paper-based prescribing. According to the results, 53.6%, 38.1%, and 8.3% of physicians had low, medium, and high overall satisfaction with this system, respectively. There was a statistically significant correlation between the sex and overall satisfaction with the e-prescribing system (p-value = 0.009) and the computer skill level and the prescribing methods (P-value = 0.042). Physicians face many challenges with this system, which can be divided into five main categories: technical, patient-related, healthcare providers-related, human resources, and architectural and design issues. Also, the main advantages of the e-prescribing system were process improvement, economic efficiency, and enhanced prescribing accuracy.

CONCLUSION

The custodian and service provider organizations should upgrade the necessary information technology infrastructures, including hardware, software, and network infrastructures. Furthermore, it would be beneficial to incorporate the perspectives of end users in the system design process.

E-prescribing and medication safety in community settings: A rapid scoping review

Background

Medication prescribing is essential for the treatment, curing, maintenance, and/or prevention of an illness and disease, however, medication errors remain common. Common errors including prescribing and administration, pose significant risk to patients. Electronic prescribing (e-prescribing) is one intervention used to enhance the safety and quality of prescribing by decreasing medication errors and reducing harm. E-prescribing in community-based settings has not been extensively examined.

Objective

To map and characterize the current evidence on e-prescribing and medication safety in community pharmacy settings.

Methods

We conducted a rapid scoping review of quantitative, qualitative, and mixed methods studies reporting on e-prescribing and medication safety. MEDLINE All (OVID), Embase (Elsevier), CINAHL Full Text (EBSCOHost), and Scopus (Elsevier) databases were searched December 2022 using keywords and MeSH terms related to e-prescribing, medication safety, efficiency, and uptake. Articles were imported to Covidence and screened by two reviewers. Data were extracted by a single reviewer and verified by a second reviewer using a standardized data extraction form. Findings are reported in accordance with JBI Manual for Evidence Synthesis following thematic analysis to narratively describe results.

Results

Thirty-five studies were included in this review. Most studies were quantitative (n = 22), non-experimental study designs (n = 16) and were conducted in the United States (n = 18). Half of included studies reported physicians as the prescriber (n = 18), while the remaining reported a mix of nurse practitioners, pharmacists, and physician assistants (n = 6). Studies reported on types of errors, including prescription errors (n = 20), medication safety errors (n = 9), dispensing errors (n = 2), and administration errors (n = 1). Few studies examined patient health outcomes, such as adverse drug events (n = 5).

Conclusions

Findings indicate that most research is descriptive in nature and focused primarily on rates of prescription errors. Further research, such as experimental, implementation, and evaluation mixed-methods research, is needed to investigate the effects of e-prescribing on reducing error rates and improving patient and health system outcomes.

Overcoming institutionalised barriers to digital health systems: an autoethnographic case study of the judicialization of a digital health tool

BACKGROUND

The deployment of digital health systems may be impeded by barriers that are, or are linked to underlying enduring institutions. Attempting to challenge the barriers without addressing the underpinning institution may be ineffective. This study reflects on ways actors may surmount institutionalised barriers to the uptake of digital tools in health systems.

METHODS

I applied Institutional theory concepts to an autoethnographic case study of efforts to introduce a digital tool to provide citizens with medicines information.

RESULTS

The tool's uptake was impeded because of state regulators' institutionalised interpretation of pharmaceutical advertising laws, which rendered the tool illegal. I, along with allies beyond the health sector, successfully challenged the regulators' institutionalised interpretation of pharmaceutical advertising laws through various actions. These actions included: framing the tool as legal and constitutional, litigation, and redefining these concepts: 'advertising', 'health institution', and the role of regulatory bodies vis a vis innovation.

CONCLUSION

After identifying a barrier as being institutionalised or linked to an institution, actors might challenge such barriers by engaging in institutional work; i.e. deliberate efforts to challenge the relevant institution (e.g. a law, norm or shared belief). Institutional work may require the actions of multiple actors within and beyond the health sector, including judicial actors. Such cross-sectoral alliances are efficacious because they provide institutional workers with a broader range of strategies, framings, concepts and forums with which to challenge institutionalised barriers. However, actors beyond the health system (e.g. the judiciary) must be inquisitive about the potential implications of the digital health interventions they champion. This case justifies recent calls for more deliberate explorations within global health scholarships and practice, of synergies between law and health.

Clinical decision support systems-based interventions to improve medication outcomes: A systematic literature review on features and effects

Background: Clinical decision support systems (CDSSs) interventions were used to improve the life quality and safety in patients and also to improve practitioner performance, especially in the field of medication. Therefore, the aim of the paper was to summarize the available evidence on the impact, outcomes and significant factors on the implementation of CDSS in the field of medicine. Methods: This study is a systematic literature review. PubMed, Cochrane Library, Web of Science, Scopus, EMBASE, and ProQuest were investigated by 15 February 2017. The inclusion requirements were met by 98 papers, from which 13 had described important factors in the implementation of CDSS, and 86 were medicated-related. We categorized the system in terms of its correlation with medication in which a system was implemented, and our intended results were examined. In this study, the process outcomes (such as; prescription, drug-drug interaction, drug adherence, etc.), patient outcomes, and significant factors affecting the implementation of CDSS were reviewed. Results: We found evidence that the use of medication-related CDSS improves clinical outcomes. Also, significant results were obtained regarding the reduction of prescription errors, and the improvement in quality and safety of medication prescribed. Conclusion: The results of this study show that, although computer systems such as CDSS may cause errors, in most cases, it has helped to improve prescribing, reduce side effects and drug interactions, and improve patient safety. Although these systems have improved the performance of practitioners and processes, there has not been much research on the impact of these systems on patient outcomes.

Main Elements of National Model of Electronic Prescription System from Physicians' Point of View: A Case Study in a Developing Country

Identifying the factors and components of an electronic prescription system is of utmost importance in effective designing and implementation of this system. In this regard, the current study was conducted to determine the main factors affecting the national model of electronic prescription from the physicians' point of view. This is a cross-sectional, descriptive-analytical research carried out in 2015. Based on the census sampling method, 104 members of the board of directors of the Iranian general practitioners' associations, general practitioners' alumni association of Iran, and physicians owner of a website or weblog were selected as samples for this study. Data were collected using a valid and reliable questionnaire. After analyzing the data with SPSS software (v.16), a model was proposed using a regression algorithm. The findings indicated that accessing the current medication data and medication history of patients during prescription, and also creating the electronic patient medication record (ePMR) are the most important selective components for physicians with frequency percent of 92.1%. Moreover, from the physicians' viewpoint, the method of "transmission of prescriptions to the central national database and retrieving prescriptions information from the selected pharmacy of the patient" had the highest priority (weight coefficient) in the model of the national electronic prescription system. Therefore, the Iranian prescription system is required to be developed based on the centralized architecture and national electronic prescription database.

The usability aspects of medication-related decision support systems in the inpatient setting: A systematic review

Effort has been made to study the effect of medication-related clinical decision support systems in the inpatient setting; however, there is not much known about the usability of these systems. The goal of this study is to systematically review studies that focused on the usability aspects such as effectiveness, efficiency, and satisfaction of these systems. We systematically searched relevant articles in Scopus, Embase, and PubMed from 1 January 2000 to 1 January 2016, and found 22 articles. Based on Van Welie’s usability model, we categorized usability aspects in terms of usage indicators and means. Our results showed that evidence was mainly found for effectiveness and efficiency. They showed positive results in the usage indicators errors and safety and performance speed. The means warnings and adaptability also had mostly positive results. To date, the effects satisfaction of clinical decision support system remains understudied. Aspects such as memorability, learnability, and consistency require more attention.

Physicians' Perceptions of Electronic Prescribing with Electronic Medical Records in Kuwaiti Primary Healthcare Centres

Objectives

This study aimed to evaluate physicians' perceptions of electronic prescribing in Kuwaiti primary healthcare centres.

Methods

This cross-sectional study was conducted between June and August 2017 among 368 physicians from 25 primary healthcare centres in Kuwait. Data were collected from the participants using a self-reported questionnaire, including sociodemographic characteristics, previous experience with computers and awareness, knowledge and use of e-prescribing systems and their functional features. In addition, perceptions of the benefits and levels of satisfaction associated with e-prescribing were explored.

Results

A total of 306 physicians completed the survey (response rate: 83%). The majority had positive perceptions regarding the use of e-prescribing, particularly in terms of time-savings (86%), healthcare quality (84%), productivity (80%) and clinical workflow and efficiency (83%). However, many respondents indicated that e-prescribing systems required additional improvements in terms of functionality.

Conclusion

Most physicians in primary healthcare centres in Kuwait recognised the importance of e-prescribing to improve the quality of patient care, streamline workflow, increase productivity and reduce medical errors. However, there is a need to improve the design and infrastructure of e-prescribing systems, which may aid in the adoption of such systems in Kuwait.

Interruptions in community pharmacies: Frequency, sources, and mitigation strategies

BACKGROUND

Interruptions constitute a key part of the communication strategy for healthcare providers, including community pharmacy personnel. Previous research in other healthcare environments has shown that interruptions are very common and may present as patient safety hazards. One 1999 study, conducted in community pharmacy settings, found that interruptions were prevalent and associated with dispensing errors. In the last 20 years, pharmacies have expanded patient services and implemented new technology. Yet, it is unknown how these changes have affected interruption sources and frequency.

OBJECTIVE

The objective was to characterize the frequency and sources of pharmacist task interruptions that occur in community pharmacies.

METHODS

A cross-sectional qualitative study design was used to evaluate the frequency and sources of pharmacist task interruptions in Wisconsin community pharmacies. The participants included 9 pharmacists and 9 technicians working in 2 independently-owned, 2 mass merchandise, and 2 hospital/clinical-affiliated pharmacies.

RESULTS

Interruption rates ranged from 3 to 7 per hour across the 6 pharmacies. Sources of interruptions included: patients, technicians, self-initiated interruptions, technology used in the pharmacy, and a second pharmacist.

CONCLUSIONS

Interruptions are common in community pharmacies and the causes are multifactorial. Prudent management of interruptions in these work environments may involve improved technician training and better designs of pharmacy technology.

Improving medication-related clinical decision support

PURPOSE

Current uses of medication-related clinical decision support (CDS) and recommendations for improving these systems are reviewed.

SUMMARY

Using a systematic approach, articles published from 2007 through 2014 were identified in MEDLINE and EMBASE using MeSH terms and keywords relating to the 5 basic medication-related CDS functionalities. A total of 156 full-text articles and 28 conference abstracts were reviewed across each of the 5 areas: drug-drug interaction (DDI) checks (n = 78), drug allergy checks (n = 20), drug dose support (n = 55), drug duplication checks (n = 11), and drug formulary support (n = 20). The success of medication-related CDS depends on users finding the alerts valuable and acting on the information received. Improving alert specificity and sensitivity is important for all domains. Tiering is important for improving the acceptance of DDI alerts. The ability to perform appropriate cross-sensitivity checks is key to producing appropriate drug allergy checks. Drug dosage alerts should be individualized and deliver practical recommendations. How the system is configured to identify certain drug duplications is important to prevent possible patient toxicity. Accurate knowledge databases are needed to produce relevant drug formulary alerts and encourage formulary adherence. Medication-related CDS is still relatively immature in some organizations and has substantial room for improvement. For example, decision support should consider more patient-specific factors, human factors principles should always be considered, and alert specificity must be improved in order to reduce alert fatigue.

CONCLUSION

Standardization, integration of patient-specific parameters, and consideration of human factors design principles are central to realizing the potential benefits of medication-related CDS.

How Physician Perspectives on E-Prescribing Evolve over Time. A Case Study Following the Transition between EHRs in an Outpatient Clinic

BACKGROUND

Physicians are expending tremendous resources transitioning to new electronic health records (EHRs), with electronic prescribing as a key functionality of most systems. Physician dissatisfaction post-transition can be quite marked, especially initially. However, little is known about how physicians' experiences using new EHRs for e-prescribing evolve over time. We previously published a qualitative case study about the early physician experience transitioning from an older to a newer, more robust EHR, in the outpatient setting, focusing on their perceptions of the electronic prescribing functionality.

OBJECTIVE

Our current objective was to examine how perceptions about using the new HER evolved over time, again with a focus on electronic prescribing.

METHODS

We interviewed thirteen internists at an academic medical center-affiliated ambulatory care clinic who transitioned to the new EHR two years prior. We used a grounded theory approach to analyze semi-structured interviews and generate key themes.

RESULTS

We identified five themes: efficiency and usability, effects on safety, ongoing training requirements, customization, and competing priorities for the EHR. We found that for even experienced e-prescribers, achieving prior levels of perceived prescribing efficiency took nearly two years. Despite the fact that speed in performing prescribing-related tasks was highly important, most were still not utilizing system short cuts or customization features designed to maximize efficiency. Alert fatigue remained common. However, direct transmission of prescriptions to pharmacies was highly valued and its benefits generally outweighed the other features considered poorly designed for physician workflow.

CONCLUSIONS

Ensuring that physicians are able to do key prescribing tasks efficiently is critical to the perceived value of e-prescribing applications. However, successful transitions may take longer than expected and e-prescribing system features that do not support workflow or require constant upgrades may further prolong the process. Additionally, as system features continually evolve, physicians may need ongoing training and support to maintain efficiency.

Triamterene Enhances the Blood Pressure Lowering Effect of Hydrochlorothiazide in Patients with Hypertension

BACKGROUND

Triamterene, because of its potassium-sparing properties, is frequently used in combination with hydrochlorothiazide (HCTZ) to treat patients with hypertension. By inhibiting the epithelial sodium channel (ENaC) in the cortical collecting duct, triamterene reduces potassium secretion, thus reducing the risk of hypokalemia. Whether triamterene has an independent effect on blood pressure (BP) has not been well studied.

OBJECTIVE

To determine if triamterene provides an effect to further lower BP in patients treated with HCTZ.

DESIGN

We conducted an observational study using electronic medical record data from the Indiana Network for Patient Care. Participants were 17,291 patients with the diagnosis of hypertension between 2004 and 2012.

MAIN MEASURES

BP was the primary outcome. We compared the BP between patients who were taking HCTZ, with and without triamterene, either alone or in combination with other antihypertensive medications, by using a propensity score analysis. For each medication combination, we estimated the propensity score (i.e., probability) of a patient receiving triamterene using a logistic regression model. Patients with similar propensity scores were stratified into subclasses and BP was compared between those taking triamterene or not within each subclass; the effect of triamterene was then assessed by combining BP differences estimated from all subclasses.

KEY RESULTS

The mean systolic BP in the triamterene + HCTZ group was 3.8 mmHg lower than in the HCTZ only group (p < 0.0001); systolic BP was similarly lower for patients taking triamterene with other medication combinations. Systolic BP reduction was consistently observed for different medication combinations. The range of systolic BP reduction was between 1 and 4 mm Hg, depending on the concurrently used medications.

CONCLUSIONS

In the present study, triamterene was found to enhance the effect of HCTZ to lower BP. In addition to its potassium-sparing action, triamterene's ability to lower BP should also be considered.

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.

Challenges to the implementation of a nationwide electronic prescribing network in primary care: a qualitative study of users' perceptions

BACKGROUND AND OBJECTIVE

The objective of this study was to identify physicians' and pharmacists' perceptions of the challenges and benefits to implementing a nationwide electronic prescribing network linking medical clinics and community pharmacies in Quebec, Canada.

METHODS

Forty-nine people (12 general practitioners, 2 managers, 33 community pharmacists, and 2 pharmacy staff members) from 40 points of care (10 primary care clinics (42% of all the connected sites) and 30 community pharmacies (44%)) were interviewed in 2013. Verbatim transcripts were analyzed using thematic analysis.

RESULTS

A low level of network use was observed. Most pharmacists processed e-prescriptions by manual entry instead of importing electronically. They reported concerns about potential errors generated by importing e-prescriptions, mainly due to the instruction field. Paper prescriptions were still perceived as the best means for safe and effective processing of prescriptions in pharmacies. Speed issues when validating e-prescription messages were seen as an irritant by physicians, and resulted in several of them abandoning transmission. Displaying the medications based on the dispensing data was identified as the main obstacle to meaningful use of medication histories.

CONCLUSIONS

Numerous challenges impeded realization of the benefits of this network. Standards for e-prescription messages, as well as rules for message validation, need to be improved to increase the potential benefits of e-prescriptions. Standard drug terminology including the concept of clinical medication should be developed, and the implementation of rules in local applications to allow for the classification and reconciliation of medication lists from dispensing data should be made a priority.

Evaluation of electronic prescription implications in Turkey: an investigation of the perceptions of physicians

BACKGROUND

Electronic prescribing (e-prescribing) is an evolving area of healthcare information technology that aims to support physician decision-making by capturing, reviewing, and issuing medical prescriptions with high potential for improving the quality and safety of the process.

PURPOSE

To describe physician perception of e-prescription use in healthcare organizations that work with social security and to evaluate their infrastructures for MEDULA (an information system for billing and other health informatics) in healthcare organizations in Turkey.

METHODS

A cross-sectional survey design was used for this study. A convenience sample of physicians in eight general hospitals and in two oral and dental health centers of the Ministry of Health in Turkey were surveyed.

RESULTS

Survey response rate was 47% (248/425). The majority of physicians (62%) support e-prescribing but have not used an electronic signature for prescriptions (78.2%). Almost half of them believe that e-prescriptions would positively contribute to patient safety (43%)

LINKING EVIDENCE TO ACTION

Our study provides a first look at the perceptions of physicians regarding the implications of e-prescriptions, which became mandatory on January 15, 2013, in Turkey. Advocates of e-prescribing have suggested that additional efforts are needed to strengthen clinical decision systems. Physicians and nurses are better able to adopt e-prescribing systems and to view them positively if they recognize the limitations of paper-based prescribing and understand the utility of electronic systems in addressing some of these limitations. This study represents a starting point for government and related organizations to improve their knowledge on how well the implied benefits of e-prescriptions are realized in their acquisition, appraisal, and use in health policy decision-making and health systems.

Towards creating the perfect electronic prescription

Significant strides have been made in electronic (e)-prescribing standards and software applications that have further fueled the adoption and use of e-prescribing. However, for e-prescribing to realize its full potential for improving the safety, effectiveness, and efficiency of prescription drug delivery, important work remains to be carried out. This perspective describes the ultimate goal of all e-prescribing stakeholders including prescribers and dispensing pharmacists: a clear, complete, and unambiguous e-prescription order that can be seamlessly received, processed, and fulfilled at the dispensing pharmacy without the need for additional clarification from the prescriber. We discuss the challenges to creating the perfect e-prescription by focusing on selected data segments and data fields that are available in the new e-prescription transaction as defined in the NCPDP SCRIPT Standard and suggest steps that could be taken to move the industry closer to achieving this vision.

The effects of electronic prescribing by community-based providers on ambulatory medication safety

BACKGROUND

US federal policies are incentivizing use of electronic prescribing (e-prescribing) to improve safety. However, little is known about e-prescribing's actual impact on medication safety over time. A study was conducted to assess the effect of implementing a commercial electronic health record (EHR) with e-prescribing on rates and types of prescribing errors. Understanding safety effects from e-prescribing will be important as providers increasingly e-prescribe.

METHODS

Prescriptions written by 20 community-based primary care providers in the Hudson Valley region of New York from November 2008 to November 2009 were retrospectively studied. All providers adopted a commercial EHR with robust clinical decision support and extensive technical support to aid in prescribing. Errors were identified by standardized prescription and chart review.

RESULTS

Some 1,629 prescriptions were analyzed at three months postimplementation, and 1,738 prescriptions were analyzed at one year postimplementation. Use of e-prescribing resulted in relatively low error rates (6.0 errors per 100 prescriptions). These rates were sustained over time but without further improvement (6.0 versus 4.5 errors per 100 prescriptions, p = .15). Antibiotics were the class of medications most frequently involved (12.7% of overall errors), and direction errors were most common (24% of errors).

CONCLUSIONS

This study is the first, as far as known, to quantitatively evaluate prescribing errors early after EHR implementation and after sustained use among community-based primary care providers. Relatively low rates of errors with e-prescribing were found early and after prolonged use. Extensive support for providers before, during, and after implementation may mitigate potential safety threats from implementation of an EHR system and result in sustained safety benefits over the long-term.

Implementing an E-prescribing system in outpatient mental health programs

This study describes the implementation and evaluation of an electronic prescription ordering system and feedback report in three community-based mental health outpatient agencies and the usefulness of the system in improving psychiatrists' prescribing behavior. Using the e-prescribing system as a data collection tool, feedback on evidence based prescribing practices for patients diagnosed with schizophrenia spectrum disorder or major affective disorder was provided to agency directors and prescribers via a monthly report. The results of the project were that e-prescribing tools can be installed at a reasonable cost with a short start up period. Although the feedback intervention did not show a significant reduction in questionable prescribing patterns, we should continue to investigate how to best use HIT to improve safety, reduce costs, and enhance the quality of healthcare. A better understanding of what prescribers find useful and the reasons why they are prescribing non-evidenced based medications is needed if interventions of this type are to be effective. Given the availability of administrative claims data and electronic prescribing technology, considerable potential exists to provide useful information for monitoring and clinical decision making in public mental health systems.

User experiences with different regional health information exchange systems in Finland

PURPOSE

The interest in cross-organizational Health Information Exchange (HIE) is increasing at regional, national and cross-European levels. The purpose of our study was to compare user experiences (usability) of different regional health information exchange system (RHIE) types as well as the factors related to the experienced level of success of different RHIE system types.

METHODS

A web-based questionnaire was sent to 95% of Finnish physicians aged between 25 and 65 years of age. RHIE systems were mainly available in the public sector and only in certain regions. Those 1693 physicians were selected from the 3929 respondents of the original study, who met these criteria. The preferred means (paper/fax vs. electronic) of cross-organizational HIE, and replies to the 11 questions measuring RHIE success were used as the main dependent variables.

RESULTS

Two thirds (73%) of the primary care physicians and one third (33%) of the specialized care physicians replied using an electronic RHIE system rather than paper or fax as a primary means of cross-organizational HIE. Respondents from regions where a regional virtual EHR (type 3) RHIE system was employed had used electronic means rather than paper HIE to a larger extend compared to their colleagues in regions where a master patient index-type (type 1) or web distribution model (type 2) RHIE system was used. Users of three local EHR systems preferred electronic HIE to paper to a larger extend than users of other EHR systems. Experiences with an integrated RHIE system (type 3) were more positive than those with other types or RHIE systems.

CONCLUSIONS

The study revealed User preferences for the integrated virtual RHIE-system (type 3) over the master index model (type 1) or web distribution model (type 2). Success of individual HIE tasks of writing, sending and reading were impacted by the way these functionalities were realized in the EHR systems. To meet the expectations of increased efficiency, continuity, safety and quality of care, designers of HIE systems also need to take into account the different HIE needs of primary care clinicians and their secondary care colleagues in hospitals. Both national legislation and local interpretations of data protection possibly hinder the full use of any RHIE systems. These findings should be taken into account when designing usable HIE systems. More qualitative research is needed on specific features of those local systems that are associated with positive or negative user experience.

Barriers and facilitators to implementing electronic prescription: a systematic review of user groups' perceptions

OBJECTIVE

We conducted a systematic review identifying users groups' perceptions of barriers and facilitators to implementing electronic prescription (e-prescribing) in primary care.

METHODS

We included studies following these criteria: presence of an empirical design, focus on the users' experience of e-prescribing implementation, conducted in primary care, and providing data on barriers and facilitators to e-prescribing implementation. We used the Donabedian logical model of healthcare quality (adapted by Barber et al) to analyze our findings.

RESULTS

We found 34 publications (related to 28 individual studies) eligible to be included in this review. These studies identified a total of 594 elements as barriers or facilitators to e-prescribing implementation. Most user groups perceived that e-prescribing was facilitated by design and technical concerns, interoperability, content appropriate for the users, attitude towards e-prescribing, productivity, and available resources.

DISCUSSION

This review highlights the importance of technical and organizational support for the successful implementation of e-prescribing systems. It also shows that the same factor can be seen as a barrier or a facilitator depending on the project's own circumstances. Moreover, a factor can change in nature, from a barrier to a facilitator and vice versa, in the process of e-prescribing implementation.

CONCLUSIONS

This review summarizes current knowledge on factors related to e-prescribing implementation in primary care that could support decision makers in their design of effective implementation strategies. Finally, future studies should emphasize on the perceptions of other user groups, such as pharmacists, managers, vendors, and patients, who remain neglected in the literature.

A theoretical approach to electronic prescription system: lesson learned from literature review

CONTEXT

The tendency to use advanced technology in healthcare and the governmental policies have put forward electronic prescription. Electronic prescription is considered as the main solution to overcome the major drawbacks of the paper-based medication prescription, such as transcription errors. This study aims to provide practical information concerning electronic prescription system to a variety of stakeholders.

EVIDENCE ACQUISITION

In this review study, PubMed, ISI Web of Science, Scopus, EMBASE databases, Iranian National Library Of Medicine (INLM) portal, Google Scholar, Google and Yahoo were searched for relevant English publications concerning the problems of paper-based prescription, and concept, features, levels, benefits, stakeholders and standards of electronic prescription system.

RESULTS

There are many problems with the paper prescription system which, according to studies have jeopardized patients' safety and negatively affected the outcomes of medication therapy. All of these problems are remedied through the implementation of e-prescriptions.

CONCLUSIONS

The sophistication of electronic prescription and integration with EHR will become a reality, if all its stakeholders collaborate in developing fast and secure electronic prescription systems. It is plausible that the required infrastructure should be provided for implementation of the national integrated electronic prescription systems in countries without the system. Given the barriers to the implementation and use, policymakers should consider multiple strategies and offer incentives to encourage e-prescription initiatives. This will result in widespread adoption of the system.

Impacts of second-generation electronic prescriptions on the medication management process in primary care: a systematic review

OBJECTIVE

To describe second-generation electronic prescription (eRx) technologies and identify their impacts on the medication management process in primary care. Second-generation eRx technologies have focused on networking various stakeholders so that they can communicate electronically.

METHOD

Using key words, a search was conducted of the relevant databases up to January 2011. A manual search was conducted of the bibliographies of the studies as well as the prior systematic reviews found. The tables of contents of the major periodicals in the field were also searched. This included studies of the impacts of eRx technologies that allow electronic circulation of information between prescription sites and dispensing sites, independent of the methodology used. A structured form was used to extract the data. The studies' impacts were classified by stage in the medication management process (prescription, transmission of the prescription, execution of the prescription and use of the medication).

RESULTS

Nineteen observational studies were included in this review. Most of them (10/19) have evaluated users' perceptions using interviews, focus groups or questionnaires. Two technology models stand out: the push model, under which the prescriber directs the prescription toward a specific pharmacy, and the pull model, under which any authorized pharmacy can download a given prescription into its system. The push model is the most widely used, particularly in the United States. Communication between prescribers and dispensers is usually unidirectional, and communications standards have to be refined. The only demonstrated impacts of second-generation eRx technologies were found at two levels: positive impacts on the quality of the pharmacological profile available to professionals, and negative impacts on the execution of prescriptions in pharmacies. Stakeholders' perceptions were mixed and reflected considerable differences according to context, the type of technology used, the intensity of its use and its maturity. Electronic transmission of prescriptions provides a new way to monitor patient compliance.

CONCLUSION

There is little empirical data demonstrating benefits to second-generation eRx technologies, even if it is a highly promoted model for improving primary care quality. More research is required, with studies that measure the impacts of second-generation technologies using empirical data and conducted in the context of actual use. Future studies should also employ the same terminology and provide full descriptions of context, type of technology and intensity of use.

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

E-prescribing, the health information technology (HIT) that enables prescribers to electronically transmit prescriptions to community pharmacies, has been touted as a solution for improving patient safety and overall quality of care. However, the impact of HIT, such as e-prescribing on medication errors in acute care settings, has been widely studied and shows that if poorly designed or implemented, HIT can pose a risk to patient safety by introducing a source of medication errors. Unlike acute care settings, safety issues related to e-prescribing in primary care settings (where e-prescriptions are generated and transmitted) and pharmacies (where e-prescriptions are received) have not received as much attention in the literature. This paper provides a focused review of patient safety issues related to using e-prescribing systems in primary care and pharmacies. In addition, the paper proposes using human factors engineering concepts to study e-prescribing safety in pharmacies and primary care settings to identify safety problems and possible mechanisms for improvement.

Adoption of and experience with e-prescribing by primary care physicians

BACKGROUND

The impetus of electronic prescribing (e-prescribing) is the reduction of preventable medication errors by generating a legible prescription checked via e-prescribing software for drug-drug and other interactions. Although the adoption of e-prescribing among physicians is growing, the Institute of Medicine's recommendations that all prescriptions be routed electronically by 2010 certainly has not been met.

OBJECTIVES

To provide an update on e-prescribing use among primary care physicians (PCPs), describe their experience with e-prescribing, and provide insight into prescribers' decisions to implement e-prescribing in their practices.

METHODS

An Internet-based survey was administered to a national convenience sample of physicians. The respondents were categorized into e-prescribers or non-e-prescribers. Data to describe demographic characteristics, respondents' experiences with e-prescribing, and respondents' decision to implement e-prescribing were collected. Nonparametric tests were used to test differences in the factors influencing e-prescribers' and traditional prescribers' decisions about electronic prescription implementation.

RESULTS

Four hundred forty-three PCPs participated in the study. There were no significant differences in the demographic characteristics of e-prescribers and non-e-prescribers. Most e-prescribers (83%) reported satisfaction with their e-prescribing system and a preference for e-prescribing over traditional prescribing. Although 22% of respondents indicated that they have started and stopped e-prescribing, most have resumed or intended to resume e-prescribing in the near future. More than half of the respondents reported that they are experiencing problems with their e-prescribing software.

CONCLUSIONS

E-prescribing appears to be present in many types of primary care practices and geographic areas of the country. Despite their satisfaction with and preference for e-prescribing, PCPs still appear to be experiencing problems with e-prescribing software. Implications of these study results for the pharmacy profession are discussed.

Transmitting and processing electronic prescriptions: experiences of physician practices and pharmacies

OBJECTIVE

A core feature of e-prescribing is the electronic exchange of prescription data between physician practices and pharmacies, which can potentially improve the efficiency of the prescribing process and reduce medication errors. Barriers to implementing this feature exist, but they are not well understood. This study's objectives were to explore recent physician practice and pharmacy experiences with electronic transmission of new prescriptions and renewals, and identify facilitators of and barriers to effective electronic transmission and pharmacy e-prescription processing.

DESIGN

Qualitative analysis of 114 telephone interviews conducted with representatives from 97 organizations between February and September 2010, including 24 physician practices, 48 community pharmacies, and three mail-order pharmacies actively transmitting or receiving e-prescriptions via Surescripts.

RESULTS

Practices and pharmacies generally were satisfied with electronic transmission of new prescriptions but reported that the electronic renewal process was used inconsistently, resulting in inefficient workarounds for both parties. Practice communications with mail-order pharmacies were less likely to be electronic than with community pharmacies because of underlying transmission network and computer system limitations. While e-prescribing reduced manual prescription entry, pharmacy staff frequently had to complete or edit certain fields, particularly drug name and patient instructions.

CONCLUSIONS

Electronic transmission of new prescriptions has matured. Changes in technical standards and system design and more targeted physician and pharmacy training may be needed to address barriers to e-renewals, mail-order pharmacy connectivity, and pharmacy processing of e-prescriptions.

Electronic prescribing within an electronic health record reduces ambulatory prescribing errors

BACKGROUND

Health policy forces are promoting the adoption of interoperable electronic health records (EHRs) with electronic prescribing (e-prescribing). Despite the promise of EHRs with e-prescribing to improve medication safety in ambulatory care settings--where most prescribing occurs and where errors are common--few studies have demonstrated its effectiveness. A study was conducted to assess the effect of an e-prescribing system with clinical decision support, including checks for drug allergies and drug-drug interactions, that was integrated within an EHR on rates of ambulatory prescribing errors.

METHODS

In a prospective study using a nonrandomized, pre-post design with concurrent controls, 6 providers who used a commercial e-prescribing system were compared with 15 providers who remained paper-based from September 2005 through July 2008. Prescribing errors were identified by a standardized prescription and chart review.

RESULTS

Some 2,432 paper prescriptions at baseline and 2,079 prescriptions at one year were analyzed. Error rates for e-prescribing adopters decreased 1.5-fold--from 26.0 errors per 100 prescriptions at baseline (95% confidence interval [CI], 17.4-38.9) to 16.0 errors per 100 prescriptions at one year (95% CI, 12.7-20.2; p = .09). Error rates remained unchanged for nonadopters (37.3 per 100 prescriptions at baseline, 95% CI, 27.6-50.2, versus 38.4 per 100 prescriptions at one year, 95% CI 27.4-53.9; p = .54). Error rates for e-prescribing adopters were significantly lower than for nonadopters at one year (p < .001). Illegibility errors were high at baseline and eliminated by e-prescribing.

CONCLUSIONS

The preliminary findings from this small group of providers suggest that e-prescribing systems may decrease ambulatory prescribing errors, which are occurring at high rates among community-based providers.

Developing public health clinical decision support systems (CDSS) for the outpatient community in New York City: our experience

BACKGROUND

Developing a clinically relevant set of quality measures that can be effectively used by an electronic health record (EHR) is difficult. Whether it is achieving internal consensus on relevant priority quality measures, communicating to EHR vendors' whose programmers generally lack clinical contextual knowledge, or encouraging implementation of EHR that meaningfully impacts health outcomes, the path is challenging. However, greater transparency of population health, better accountability, and ultimately improved health outcomes is the goal and EHRs afford us a realistic chance of reaching it in a scalable way.

METHOD

In this article, we summarize our experience as a public health government agency with developing measures for a public health oriented EHR in New York City in partnership with a commercial EHR vendor.

RESULTS

From our experience, there are six key lessons that we share in this article that we believe will dramatically increase the chance of success. First, define the scope and build consensus. Second, get support from executive leadership. Third, find an enthusiastic and competent software partner. Fourth, implement a transparent operational strategy. Fifth, create and test the EHR system with real life scenarios. Last, seek help when you need it.

CONCLUSIONS

Despite the challenges, we encourage public health agencies looking to build a similarly focused public health EHR to create one both for improved individual patient as well as the larger population health.

Meaningful use of electronic prescribing in 5 exemplar primary care practices

PURPOSE

Successful use of electronic prescribing (e-prescribing) is a key requirement for demonstrating meaningful use of electronic health records to qualify for federal incentives. Currently, many physicians who implement e-prescribing fail to make substantial use of these systems, and little is known about factors contributing to successful e-prescribing use. The objective of this study was to identify successful implementation and use techniques.

METHODS

We conducted a multimethod qualitative case study of 5 ambulatory primary care practices identified as exemplars of effective e-prescribing. The practices were identified by a group of e-prescribing experts. Field researchers conducted in-depth interviews and observed prescription-related workflow in these practices.

RESULTS

In these exemplar practices, successful use of e-prescribing required practice transformation. Practice members reported extensive efforts to redesign work processes to take advantage of e-prescribing capabilities and to create specific e-prescribing protocols to distribute prescription-related work among practice team members. These practices had substantial resources to support e-prescribing use, including local physician champions, ongoing training for practice members, and continuous on-site technical support. Practices faced considerable challenges during use of e-prescribing, however, deriving from problems coordinating new work processes with pharmacies and ineffective health information exchange that required workarounds to ensure the completeness of patient medical records.

CONCLUSIONS

More widespread implementation and effective use of e-prescribing in ambulatory care settings will require practice transformation efforts that focus on work process redesign while being attentive to effects on patient and pharmacy involvement in prescribing. Improved health information exchange is required to fully realize expected quality, safety, and efficiency gains of e-prescribing.

Transitioning between electronic health records: effects on ambulatory prescribing safety

BACKGROUND

Healthcare providers previously using older electronic health records (EHRs) with electronic prescribing (e-prescribing) are transitioning to newer systems to be eligible for federal meaningful use incentives. Little is known about the safety effects of transitioning between systems.

OBJECTIVE

To assess the effect of transitioning between EHR systems on rates and types of prescribing errors, as well as provider perceptions about the effect on prescribing safety.

DESIGN, PARTICIPANTS

Prospective, case study of 17 physicians at an academic-affiliated ambulatory clinic from February 2008 through August 2009. All physicians transitioned from an older EHR with minimal clinical decision support (CDS) for e-prescribing to a newer EHR with more robust CDS.

MAIN MEASUREMENTS

Prescribing errors were identified by standardized prescription and chart review. A novel survey instrument was administered to evaluate provider perceptions about prescribing safety.

KEY RESULTS

We analyzed 1298 prescriptions at baseline, 1331 prescriptions 12 weeks post-implementation, and 1303 prescriptions one year post-implementation. Overall prescribing error rates were highest at baseline (35.7 per 100 prescriptions, 95% confidence interval (CI) 23.2-54.8) and lowest one year post-implementation (12.2 per 100 prescriptions, 95% CI 8.6-17.4) (p < 0.001). Improvement in prescribing safety was mainly a result of reducing inappropriate abbreviation errors. However, rates for non-abbreviation prescribing errors were significantly higher at 12 weeks post-implementation than at baseline (17.7 per 100 prescriptions, 95% CI 9.5-33.0 versus 8.5 per 100 prescriptions, 95% CI 4.6-15.9) (p <0.001) and no different at baseline than one year (10.2 per 100 prescriptions, 95% CI 6.2-18.6) (p = 0.337). Survey results complemented quantitative findings.

CONCLUSIONS

Results from this case study suggest that transitioning between systems, even to those with more robust CDS, may pose important safety threats. Recognizing the challenges associated with transitions and refining CDS within systems may help maximize safety benefits.

Perceptions of e-prescribing efficiencies and inefficiencies in ambulatory care

INTRODUCTION

Recent studies have demonstrated that e-prescribing takes longer than handwriting. Additional studies documenting the perceived efficiencies realized from e-prescribing from those who have implemented electronic prescribing are warranted.

METHODS

We used a mixed method study design. We report on qualitative date from 64 focus groups with clinicians and office staff from six US states. Participants used one of six e-prescribing software packages. Qualitative data from the focus groups (276 participants) were coded and analyzed using NVivo software. Quantitative data regarding perceived efficiencies were extracted from a survey of 157 clinicians using e-prescribing.

RESULTS

Perceptions of e-prescribing included 64% reporting e-prescribing as very efficient. The next closest method was computer generated fax and prescriptions in which ∼25% rated the method as very efficient. Improvements in workflow and record keeping were noted. Perceived efficiencies were realized by decreased errors, availability of formularies at the point of prescribing and refill processing. Perceived inefficiencies noted included the need for dual systems owing to regulations preventing e-prescribing of scheduled medications as well as those introduced with incorrect information on formularies, pharmacy used, and warnings.

DISCUSSION

Overwhelmingly, clinicians and their staff confirmed the perceived efficiencies realized with the adoption of e-prescribing. Perceived efficiencies were realized in knowing formularies, processing refills, and decreasing errors. Opportunities to improve efficiencies could be realized by assuring correct information in the system.

Prescriber and staff perceptions of an electronic prescribing system in primary care: a qualitative assessment

BACKGROUND

The United States (US) Health Information Technology for Economic and Clinical Health Act of 2009 has spurred adoption of electronic health records. The corresponding meaningful use criteria proposed by the Centers for Medicare and Medicaid Services mandates use of computerized provider order entry (CPOE) systems. Yet, adoption in the US and other Western countries is low and descriptions of successful implementations are primarily from the inpatient setting; less frequently the ambulatory setting. We describe prescriber and staff perceptions of implementation of a CPOE system for medications (electronic- or e-prescribing system) in the ambulatory setting.

METHODS

Using a cross-sectional study design, we conducted eight focus groups at three primary care sites in an independent medical group. Each site represented a unique stage of e-prescribing implementation - pre/transition/post. We used a theoretically based, semi-structured questionnaire to elicit physician (n = 17) and staff (n = 53) perceptions of implementation of the e-prescribing system. We conducted a thematic analysis of focus group discussions using formal qualitative analytic techniques (i.e. deductive framework and grounded theory). Two coders independently coded to theoretical saturation and resolved discrepancies through discussions.

RESULTS

Ten themes emerged that describe perceptions of e-prescribing implementation: 1) improved availability of clinical information resulted in prescribing efficiencies and more coordinated care; 2) improved documentation resulted in safer care; 3) efficiencies were gained by using fewer paper charts; 4) organizational support facilitated adoption; 5) transition required time; resulted in workload shift to staff; 6) hardware configurations and network stability were important in facilitating workflow; 7) e-prescribing was time-neutral or time-saving; 8) changes in patient interactions enhanced patient care but required education; 9) pharmacy communications were enhanced but required education; 10) positive attitudes facilitated adoption.

CONCLUSIONS

Prescribers and staff worked through the transition to successfully adopt e-prescribing, and noted the benefits. Overall impressions were favorable. No one wished to return to paper-based prescribing.

Results of the Arizona Medicaid health information technology pharmacy focus groups

BACKGROUND

In 2007, a federal Medicaid Transformation Grant was awarded to design, develop, and deploy a statewide Health Information Exchange and Electronic Health Record in Arizona, United States.

OBJECTIVE

To explore the health information technology needs, knowledge, and expectations of Arizona's health care professionals, moderated focus groups were conducted. This article describes the results of the pharmacist focus groups.

METHODS

Focus group activities included a brief presentation, completion of a paper-based survey, and group discussion. The methods included solicitation by invitation, participant selection, meeting content, collaterals, focus group execution, recording, analysis, and discerning comparability among groups.

RESULTS

Pharmacy focus group discussions centered on electronic prescribing, including the anticipated advantages: reducing handwriting interpretation errors, improving formulary compliance, improving communication with prescribers, increasing efficiency, and ensuring data accuracy. Disadvantages included: medication errors, inadequate training and knowledge of software applications, and inflated patient expectations.

CONCLUSIONS

Pharmacists ranked e-prescribing as the highest priority feature of an electronic health system.

E-prescribing and primary noncompliance: physician and patient experience

PURPOSE/OBJECTIVES

The success of medication therapy, regardless of how it is prescribed, hinges on patient adherence starting with primary compliance (filling prescriptions.) This study examined primary noncompliance (PNC) in the context of e-prescribing (e-Rx).

PRIMARY PRACTICE SETTING

An e-Rx-promotion project was supplemented by mailed alerts to clinicians in private practice regarding PNC to improve adherence to therapy. We included physicians who were willing to participate and plan members who received prescriptions from these providers. Physicians and patients were surveyed about their experience with e-Rx and PNC.

FINDINGS/CONCLUSIONS

The rate of PNC was 15%. Provider survey respondents indicated satisfaction with e-Rx (83%.) Most of them were satisfied with improved office efficiency (74%) and certain e-Rx features. Patient survey results indicated that the top 2 reasons for PNC were perception of lack of efficacy and concern about side effects. High cost and absence of symptoms ranked next. Only 34% of patients felt that e-Rx improves medication safety significantly, and many of them were not aware of e-Rx use by their physicians. Most patients and physicians reported being comfortable discussing PNC.

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

PNC is a significant cause of poor adherence to drug therapy, and nonfinancial patient concerns are the primary reason. Mailed PNC alerts to providers are resource intensive and may be supplanted by certain e-Rx standards. Clinicians who adopted e-Rx report a largely positive experience with e-Rx. Recent changes in Medicare rules will impact the use of this technology but challenges remain and require continued support to hasten the adoption of e-Rx. Case management programs may improve primary compliance by incorporating exchange of e-Rx data.

eHealth usage patterns of European general practitioners: a five-year (2002-2007) comparative study

PURPOSE

This paper provides a five-year (2002-2007) comparative segmentation analysis of how the Internet and dedicated health networks are used by European general practitioners (GPs) and the extent to which external factors affect their use of various eHealth services.

METHODS

Two cross-national sets of survey data collected in 2002 (n=3512) and 2007 (n=3948) have been analyzed. These databases provide information on physicians' eHealth uses in EU-15 countries, including sociodemographic indicators such as country, age, sex, location, and size of the medical practice.

RESULTS

A total of 3512 and 3948 physicians, respectively, participated in the 2002 and 2007 studies. The percentage of GPs accessing the Internet or a dedicated health network increased from 64.5% in 2002 to 77.1% in 2007. Only these physicians were included in the latent class cluster analyses performed on both datasets, yielding three segments of eHealth users plus a group of non-Internet users. Thus, the following four final segments were identified in the years 2002 and 2007: 'Information Searchers/Average Users', 'Advanced Users/Adv. Users (ePrescribers)', 'Laggards', and 'Non-Internet Users'. Contingency table analyses relating external indicators to physicians' usage patterns of eHealth services confirmed strong country differences, low to moderate age influences reflecting a cohort effect, and moderate effects of practice size, both in 2002 and 2007. Conversely, very weak influences were observed for physicians' sex and location of the medical practice.

CONCLUSION

A positive evolution is clearly observable in European primary care physicians' use of eHealth, mainly with regard to online medical information searches, use of electronic health care records, and (to a lesser extent) electronic transfers of patient data. The international comparative profiling of European GPs' eHealth usage patterns contributes to more efficient and continually adapted promotion strategies, aimed at fostering the diffusion of eHealth applications among medical professionals of the analyzed EU-15 countries.

Electronic prescribing improves medication safety in community-based office practices

BACKGROUND

Although electronic prescribing (e-prescribing) holds promise for preventing prescription errors in the ambulatory setting, research on its effectiveness is inconclusive.

OBJECTIVE

To assess the impact of a stand-alone e-prescribing system on the rates and types of ambulatory prescribing errors.

DESIGN, PARTICIPANTS

Prospective, non-randomized study using pre-post design of 15 providers who adopted e-prescribing with concurrent controls of 15 paper-based providers from September 2005 through June 2007.

INTERVENTION

Use of a commercial, stand-alone e-prescribing system with clinical decision support including dosing recommendations and checks for drug-allergy interactions, drug-drug interactions, and duplicate therapies.

MAIN MEASURES

Prescribing errors were identified by a standardized prescription and chart review.

KEY RESULTS

We analyzed 3684 paper-based prescriptions at baseline and 3848 paper-based and electronic prescriptions at one year of follow-up. For e-prescribing adopters, error rates decreased nearly sevenfold, from 42.5 per 100 prescriptions (95% confidence interval (CI), 36.7-49.3) at baseline to 6.6 per 100 prescriptions (95% CI, 5.1-8.3) one year after adoption (p < 0.001). For non-adopters, error rates remained high at 37.3 per 100 prescriptions (95% CI, 27.6-50.2) at baseline and 38.4 per 100 prescriptions (95% CI, 27.4-53.9) at one year (p = 0.54). At one year, the error rate for e-prescribing adopters was significantly lower than for non-adopters (p < 0.001). Illegibility errors were very high at baseline and were completely eliminated by e-prescribing (87.6 per 100 prescriptions at baseline for e-prescribing adopters, 0 at one year).

CONCLUSIONS

Prescribing errors may occur much more frequently in community-based practices than previously reported. Our preliminary findings suggest that stand-alone e-prescribing with clinical decision support may significantly improve ambulatory medication safety.

Showing Your Work: Impact of annotating electronic prescriptions with decision support results

e-Prescribing systems with decision support do not routinely communicate an adequate amount of information regarding the prescribers' decision to pharmacists. To address this communication gap in the e-prescribing process, we implemented a system called Show Your Work (SYW) that appends alerts and override comments to e-prescriptions generated by an e-prescribing system. To assess the quantitative impact of this system, we conducted a randomized, double-blinded, controlled study to assess pharmacy callback rates and types, and to uncover any unintended consequences of the annotations. Each day, SYW output across the enterprise was turned "on" or "off" randomly for all e-prescriptions. A convenience sample of three pharmacies, blinded to SYW status, submitted callback logs each day. These logs were used to calculate the rate of and reason for callbacks. At the conclusion of the study, we surveyed the 50 most frequently used pharmacies in our area to assess the impact of SYW on satisfaction and communication. A total of 202 callbacks had occurred yielding a callback rate of 45 callbacks/1000 prescriptions for SYW "on" days and 40 callbacks/1000 prescriptions for "off" days (p=0.4). We received 38 surveys (76% response rate) with 33 respondents commenting about SYW. Most respondents agreed (69%) that SYW favorably impacted callbacks--especially with pediatric prescriptions (82%). Comments suggested that SYW increased callbacks where necessary and decreased them in other situations, but did not contribute to unnecessary callbacks. These findings support the continued and potentially expanded use of SYW by e-prescribing systems to enhance communication with pharmacists.

E-prescribing: clinical implications for patients with diabetes

With the recent Center for Medicare and Medicaid Services and stimulus package incentives for health information technology, many clinicians are expected to adopt or enhance their use of e-prescribing systems. E-prescribing has nearly eradicated medication errors resulting from prescriber handwriting interpretations, yet several other patient-care and workflow benefits still remain a promise. As prescribers select or update their e-prescribing systems (whether stand-alone or integrated with electronic health records), close attention is needed to the e-prescribing application features and level of clinical decision support to avoid clinical blind spots, including incomplete or inaccurate patient medication lists, poor drop-down menu or screen design, and lack of clinically relevant and actionable drug interaction and drug allergy alerts. This article presents three case studies that highlight common e-prescribing problems involving diabetes patients.

Perceptions of standards-based electronic prescribing systems as implemented in outpatient primary care: a physician survey

OBJECTIVE To compare the experiences of e-prescribing users and nonusers regarding prescription safety and workload and to assess the use of information from two e-prescribing standards (for medication history and formulary and benefit information), as they are implemented. DESIGN Cross-sectional survey of physicians who either had installed or were awaiting installation of one of two commercial e-prescribing systems. MEASUREMENTS Perceptions about medication history and formulary and benefit information among all respondents, and among e-prescribing users, experiences with system usability, job performance impact, and amount of e-prescribing. RESULTS Of 395 eligible physicians, 228 (58%) completed the survey. E-prescribers (n = 139) were more likely than non-e-prescribers (n = 89) to perceive that they could identify clinically important drug-drug interactions (83 versus 67%, p = 0.004) but not that they could identify prescriptions from other providers (65 versus 60%, p = 0.49). They also perceived no significant difference in calls about drug coverage problems (76 versus 71% reported getting 10 or fewer such calls per week; p = 0.43). Most e-prescribers reported high satisfaction with their systems, but 17% had stopped using the system and another 46% said they sometimes reverted to handwriting for prescriptions that they could write electronically. The volume of e-prescribing was correlated with perceptions that it enhanced job performance, whereas quitting was associated with perceptions of poor usability. CONCLUSIONS E-prescribing users reported patient safety benefits but they did not perceive the enhanced benefits expected from using standardized medication history or formulary and benefit information. Additional work is needed for these standards to have the desired effects.

Evaluating User Satisfaction with an Electronic Prescription System in a Primary Care Group

Introduction: Electronic prescribing has been proposed as an important strategy to reduce medication errors, improve the quality of patient care and create savings in health care costs. Despite these potential advantages, user satisfaction plays a significant role in the success of its implementation. Hence, this study aims to examine users’ satisfaction and factors associated with satisfaction regarding an electronic prescription system implemented in the National Healthcare Group Polyclinics in Singapore. Materials and Methods: An anonymous survey was administered in October 2007 to all physicians, pharmacists and pharmacy technicians working in the 9 National Healthcare Group Polyclinics. Results: Respondents included 118 doctors and 61 pharmacy staff. The overall level of satisfaction with electronic prescribing was high. Doctors and pharmacists reported a high degree of agreement that electronic prescribing reduces prescribing errors and interventions, and they did not want to go back to the paper-based system. Users were generally satisfied with the functionality of the system but there was some degree of workflow interference particularly for the pharmacy staff. Only 56.9% of the pharmacy respondents expressed satisfaction with the review function of the electronic prescription system and only 51.8% and 60% were satisfied when processing prescriptions that included items to be purchased from an external pharmacy or prescriptions with amendments. The results also revealed that satisfaction with the system was more associated with users’ perceptions about the electronic prescription system’s impact on productivity than quality of care. Conclusion: The survey results indicate that the implementation of the electronic prescription system has gone reasonably well. The survey findings provide opportunities for system and workflow enhancement, which is important as these issues could affect the acceptability of a new technology and the speed of diffusion within an organisation.
