Randomized controlled trial of an informatics-based intervention to increase statin prescription for secondary prevention of coronary disease.

OBJECTIVE: Suboptimal treatment of hyperlipidemia in patients with coronary artery disease (CAD) is well documented. We report the impact of a computer-assisted physician-directed intervention to improve secondary prevention of hyperlipidemia. DESIGN AND SETTING: Two hundred thirty-five patients under the care of 14 primary care physicians in an academically affiliated practice with an electronic health record were enrolled in this proof-of-concept physician-blinded randomized, controlled trial. Each patient with CAD or risk equivalent above National Cholesterol Education Program-recommended low-density lipoprotein (LDL) treatment goal for greater than 6 months was randomized, stratified by physician and baseline LDL. Physicians received a single e-mail per intervention patient. E-mails were visit independent, provided decision support, and facilitated "one-click" order writing. MEASUREMENTS: The primary outcomes were changes in hyperlipidemia prescriptions, time to prescription change, and changes in LDL levels. The time spent using the system was assessed among intervention patients. RESULTS: A greater proportion of intervention patients had prescription changes at 1 month (15.3% vs 2%, P=.001) and 1 year (24.6% vs 17.1%, P=.14). The median interval to first medication adjustment occurred earlier among intervention patients (0 vs 7.1 months, P=.005). Among patients with baseline LDLs >130 mg/dL, the first postintervention LDLs were substantially lower in the intervention group (119.0 vs 138.0 mg/dL, P=.04). Physician processing time was under 60 seconds per e-mail. CONCLUSION: A visit-independent disease management tool resulted in significant improvement in secondary prevention of hyperlipidemia at 1-month postintervention and showed a trend toward improvement at 1 year.

Prescribing errors resulting in adverse drug events: how can they be prevented?

As approximately 19% of medical errors occurring in hospitals are related to medication errors, reduction of these is one of the major goals to be achieved by healthcare providers. Medication errors may occur at different levels: i) prescribing; ii) transcription; iii) dispensing; and iv) administration. Whereas errors in transcription can be significantly reduced by computerised physician order systems, improvement of prescribing appears to be a much larger problem. Continuous support by ward pharmacists may be feasible in some hospitals, but not in the setting of ambulatory prescribing. Much hope relies on computerised physician order systems with a knowledge database for interactions, warnings on allergies and other intelligent alerts. However, these systems still have some shortcomings and it has not yet convincingly been shown that the use of this technology really improves patient safety.

Hospital implementation of computerized provider order entry systems: results from the 2003 leapfrog group quality and safety survey.

A critical element of The Leapfrog Group's strategy for advancing improvements in healthcare is its ongoing survey of hospital patient safety and quality improvement activities, including computerized provider order entry (CPOE) systems. This survey is distinct from other surveys of CPOE adoption because individual hospital responses are publicly disseminated. Furthermore, this survey offers an opportunity to explore the drivers of hospital CPOE adoption before financial incentives for patient safety proliferate, as well as an opportunity to compare the characteristics of participating and non-participating hospitals. Results from the 2003 survey show that only 3.7 percent of the 842 participating hospitals located in The Leapfrog Group's targeted regions had fully implemented a CPOE system consistent with the Leapfrog standard, although 92 percent reported at least planned or partial implementation of a CPOE system. While prior research suggests that a hospital's financial condition should be positively correlated with decisions to invest in CPOE, the analysis generally failed to detect such a relationship.

Parenteral nutrition in neonatology--to standardize or individualize?

Premature very low birth weight (< 1500 g) infants comprise one of the largest groups receiving parenteral nutrition. PN should be optimized to answer their high nutritional requirements and suit their metabolic status, but should also be validated pharmaceutically. PN can be provided as a standard, usually commercial, formulation, representing the average needs of a large group of patients. Alternatively, an individualized PN compound adapted to the patient's needs can be prescribed and prepared, usually on a daily basis. The main advantage of individually prescribed PN is that it is tailored to suit a specific patient, thereby assuring the best possible nutrition and biochemical control. Batch-produced standardized PN bags can be readily available as ward stocks in neonatal intensive care units, enabling initiation of early PN immediately after the delivery of a premature infant. Moreover, standard PN solutions incorporate expert nutritional knowledge and support. A combination of standardized PN bags, prepared under strict standardization criteria, for most neonates, with a small number of specifically tailored individualized PN formulations for those in need for them, could reduce pharmacy workload and costs and increase safety, while maintaining the desired clinical flexibility. For those in need of the individualized PN formulations, a computerized ordering system can save time, decrease prescription and compounding errors, and improve quality of nutritional care.

Physician characteristics, attitudes, and use of computerized order entry.

BACKGROUND: Computerized physician order entry (CPOE) is a widely advocated patient safety intervention, yet little is known about its adoption by attending physicians or community hospitals. METHODS: We calculated the order entry rates of attending physicians at 2 hospitals by measuring the number of orders entered directly and dividing this by the sum of orders entered directly and those written by hand. These findings were paired with the results of a survey that assessed attitudes concerning the impact of CPOE on personal efficiency, quality of care, and patient safety. RESULTS: Three hundred and fifty-six (71%) of the 502 surveys were returned by physicians, whose median order entry rate was 66%. Forty-two percent of respondents placed at least 80% of their orders electronically (high use), 26% placed 21%-79% of their orders electronically (intermediate use), and 32% placed 20% or less of their orders electronically (low use). Sex, years since medical school graduation, years in practice at the study institution, and use of computers in the outpatient arena were not meaningfully different among the 3 groups. However, use of the system to place orders varied by specialty, and those with intermediate or high use of the system were more likely than low users to have used CPOE during training and to be regular users of computers for personal activities. These physicians were more likely to believe that CPOE enabled orders to be placed efficiently, that directly entered orders were carried out more rapidly, and that such orders were associated with fewer errors. CONCLUSIONS: The adoption of CPOE by attending physicians at community hospitals varies widely. In addition to purchasing systems that support physician work flow, hospitals intent on successfully implementing CPOE should emphasize the benefits in safety and quality of this new technology.

The effect of physicians' long-term use of CPOE on their test management work practices.

OBJECTIVE: To explore physicians' work practices in relation to their long-term use of a computerized physician order entry system (CPOE). DESIGN: A cross-sectional qualitative study was conducted in four clinical units in two large Australian teaching hospitals. One hospital had used CPOE for over 10 years to order all clinical laboratory and radiology tests and view test results and the other had used the computerized viewing facility of the system for over seven years with tests ordered manually. Data were collected by non-participatory observations of physicians (55 sessions) and 28 interviews. MEASUREMENTS: Content analysis of the observation field notes, reflections on observations and interview transcripts were conducted by two researchers independently. A thematic grounded theory approach was used to derive key themes that would explain physicians work practices associated with CPOE use. RESULTS: Three themes relating to physicians' established use of CPOE were identified: (1) the effect of the hospital and clinical environment; (2) changes to work practices; and (3) physicians' management of information. Physicians' test management work practices using CPOE were related to diversity between: the hospitals; the clinical units' environment, and the users of the system. CONCLUSION: Hospitals need to understand and analyze physicians' test management work practices prior to and during the implementation of CPOE to accommodate their diverse ways of working with computerized information systems. In the current mixed media environment, physicians' use of manual and computerized information systems for sourcing and recording information impacts on efficiency and patient safety.

Overriding of drug safety alerts in computerized physician order entry.

Many computerized physician order entry (CPOE) systems have integrated drug safety alerts. The authors reviewed the literature on physician response to drug safety alerts and interpreted the results using Reason's framework of accident causation. In total, 17 papers met the inclusion criteria. Drug safety alerts are overridden by clinicians in 49% to 96% of cases. Alert overriding may often be justified and adverse drug events due to overridden alerts are not always preventable. A distinction between appropriate and useful alerts should be made. The alerting system may contain error-producing conditions like low specificity, low sensitivity, unclear information content, unnecessary workflow disruptions, and unsafe and inefficient handling. These may result in active failures of the physician, like ignoring alerts, misinterpretation, and incorrect handling. Efforts to improve patient safety by increasing correct handling of drug safety alerts should focus on the error-producing conditions in software and organization. Studies on cognitive processes playing a role in overriding drug safety alerts are lacking.

An anesthesia information system designed to provide physician-specific feedback improves timely administration of prophylactic antibiotics.

Surgical site infections are a frequent cause of morbidity and mortality and add significantly to the cost of care. One component of the national Surgical Infection Prevention (SIP) program is to ensure timely administration of prophylactic antibiotics, a key factor to reduce postoperative infection. Our anesthesia department decided to assume the responsibility for timing and administration of antibiotic prophylaxis and we initiated a multitiered approach to remind the anesthesiologist to administer the prophylactic antibiotics. We used our anesthesia clinical information system to implement practice guidelines for timely antibiotic administration and to generate reports from the database to provide specific feedback to individual care providers with the goal of ensuring that patients receive antibiotic prophylaxis within 1 h of incision. Before the initiation of this project, 69% of eligible patients received antibiotics within 60 min of the incision. After the program began, there was a steady increase in compliance to 92% 1 yr later. Provider-specific feedback increases compliance with practice guidelines related to timely administration of prophylactic antibiotics. Anesthesia information systems hold promise for implementing and monitoring new practice guidelines and the anesthesiologist may play a key role in influencing surgical outcomes by ensuring appropriate therapy that may not be directly related to anesthesia care.

Horus meets Nightingale in the modern age: How nursing communicates with pharmacy in HCIT era.

In 2002 The Australia council for Safety and Quality in Healthcare determined that problems with medicines were responsible 2-3% of all hospital admissions in Australia EMR's with codified datasets lay the foundation for significantly reducing the number of these adverse events. CPOE has well documented benefits in the reduction of order related errors. The use of information technology in pharmacy has long provided proven benefits in the diminution of pharmacy errors. The use of an electronic medication chart and positive patient identification functionality and technology (5 rights) ensures a reduction in errors at administration. Decision support at all stages of an electronic medication process reduces errors and promotes evidence based medicine. This functionality all provides a basis for addressing medication errors, however it is the seamless integration of all these components into a homogenous system that really addresses these errors. This research focuses on the communication gap between pharmacy and nursing. It is a multi-disciplinary study that defines that lack of research in this are and proposes the important questions that need to be answered in order to ensure that HCIT advancement in this area is focussed to eliminate medication errors.

E-Prescribing collaboration in Massachusetts: early experiences from regional prescribing projects.

Massachusetts payers and providers have encouraged clinician usage of e-Prescribing technology to improve patient safety, enhance office practice efficiencies, and reduce medical costs. This report describes three early pilot e-Prescribing projects as case studies. These projects identified the e-Prescribing needs of clinicians, illustrated key issues that made implementation difficult, and clarified the impact of various types of functionality. The authors identified ten key barriers: (1) previous negative technology experiences, (2) initial and long-term cost, (3) lost productivity, (4) competing priorities, (5) change management issues, (6) interoperability limitations, (7) information technology (IT) requirements, (8) standards limitations, (9) waiting for an "all-in-one solution," and (10) confusion about competing product offerings including hospital/Integrated Delivery System (IDN)-sponsored projects. In Massachusetts, regional projects have helped to address these barriers, and e-Prescribing activities are accelerating rapidly within the state.

Of lobsters, electronic medical records, and neonatal total parenteral nutrition.

At the Mayo Health System in LaCrosse, Wisconsin, there are >1000 infant total parenteral nutrition (TPN) orders placed per year. It is the most complicated order that the pharmacy fills, so a recent peer-review article in Pediatrics moved a group of us to action at our center to buy or develop a TPN calculator. We did this because no stand-alone commercial calculators were available to us, and expensive electronic medical records typically do not include TPN calculators for neonatal patients. The new software includes decision support, and the orders are consistently legible. The physician performs fewer calculations, and there are no mathematical errors. This article examines the broader significance of providers having to write their own TPN software.

e-Prescribing, efficiency, quality: lessons from the computerization of UK family practice.

Nearly all general practice physicians (GPs) in the United Kingdom (UK) have electronic health record (EHR) systems in their practices compared with perhaps 15% of primary care physicians in the United States (U.S.). Based on interviews of 13 general GPs and review of current literature, the authors argue that the historical experience of widespread electronic health record uptake in the UK provides insight into features that might motivate broad adoption in the United States. These features include electronic prescribing, improved quality and consistency of care, practice efficiencies that have both timesaving and revenue generating effects, and potential shielding from malpractice claims.

Clinical information technology gaps persist among physicians.

Physicians in smaller practices continue to lag well behind physicians in larger practices in reporting the availability of clinical information technology (IT) in their offices, according to a new national study from the Center for Studying Health System Change (HSC). The proportion of physicians reporting access to IT for each of five clinical activities increased across all practice settings between 2000-01 and 2004-05. Adoption gaps between small and large practices persisted, however, for two of the clinical activities--obtaining treatment guidelines and exchanging clinical data with other physicians--and widened for the other three--accessing patient notes, generating preventive care reminders and writing prescriptions. In contrast, clinical IT was generally as likely or more likely to be available to physicians in practices treating larger proportions of vulnerable and underserved patients as other physicians, a pattern that did not change between the two periods

The effects of creating psychological ownership on physicians' acceptance of clinical information systems.

OBJECTIVE: Motivated by the need to push further our understanding of physicians' acceptance of clinical information systems, we propose a relatively new construct, namely, psychological ownership. We situated the construct within a nomological net using a prevailing and dominant information technology adoption behavior model as a logical starting point. DESIGN: A mail survey was sent to the population of users of a regional physician order entry (POE) system aimed at speeding up the transmission of clinical data, mainly laboratory tests and radiology examinations, within a community health network. MEASUREMENTS: All scales, but one, were measured using previously validated instruments. For its part, the psychological ownership scale was developed using a multistage iterative procedure. RESULTS: Ninety-one questionnaires were returned to the researchers, for a response rate of 72.8%. Our findings reveal that, in order to foster physicians' adoption of a clinical information system, it is important to encourage and cultivate a positive attitude toward using the new system. In this connection, positive perception of the technology's usefulness is crucial. Second, results demonstrate that psychological ownership of a POE system is positively associated with physicians' perceptions of system utility and system user friendliness. Last, through their active involvement and participation, physicians feel they have greater influence on the development process, thereby developing feelings of ownership toward the clinical system. CONCLUSION: Psychological ownership's highly significant associations with user participation and crucial beliefs driving technology acceptance behaviors among physicians affirm the value of this construct in extending our understanding of POE adoption.

[Designing a module for the prevention of hypersensitivity reactions in an assisted electronic prescription system].

OBJECTIVE: To develop a module for the prevention of drug-related allergies to be integrated within the assisted electronic prescription software PRISMA. METHOD: On module design potential sources of medication errors regarding drug allergies were first analyzed, and ideal module characteristics were defined. Then a review of the literature was performed to define "group allergies", and last of all master archives were created, with their required relations being established. RESULTS: A module for the prevention of drug-related allergies in the setting of an assisted electronic prescription software was designed. By interrelating tables listing active ingredients, excipients, chemical structures/functional groups, and "group allergies" prescriptions may be interactively checked, and useful information is provided to the prescribing practitioner--as well as the whole multidisciplinary team--to help him make his/her decisions.

Will decision support in medications order entry save money? A return on investment analysis of the case of the Hong Kong hospital authority.

The computerized medications order entry system currently used in the public hospitals of Hong Kong does not have decision support features. Plans are underway to add decision support to this system to alert physicians on drug-allergy conflicts, drug-lab result conflicts, drug-drug interactions and atypical dosages. A return on investment analysis is done on this enhancement, both as an examination of whether there is a positive return on the investment and as a contribution to the ongoing discussion of the use of return on investment models in health care information technology investments. It is estimated that the addition of decision support will reduce adverse drug events by 4.2 - 8.4%. Based on this estimate, a total net saving of $44,000 - $586,000 is expected over five years. The breakeven period is estimated to be between two to four years.
