Comparison of methods for detecting medication errors in 36 hospitals and skilled-nursing facilities.

The validity and cost-effectiveness of three methods for detecting medication errors were examined. A stratified random sample of 36 hospitals and skilled-nursing facilities in Colorado and Georgia was selected. Medication administration errors were detected by registered nurses (R.N.s), licensed practical nurses (L.P.N.s), and pharmacy technicians from these facilities using three methods: incident report review, chart review, and direct observation. Each dose evaluated was compared with the prescriber's order. Deviations were considered errors. Efficiency was measured by the time spent evaluating each dose. A pharmacist performed an independent determination of errors to assess the accuracy of each data collector. Clinical significance was judged by a panel of physicians. Observers detected 300 of 457 pharmacist-confirmed errors made on 2556 doses (11.7% error rate) compared with 17 errors detected by chart reviewers (0.7% error rate), and 1 error detected by incident report review (0.04% error rate). All errors detected involved the same 2556 doses. All chart reviewers and 7 of 10 observers achieved at least good comparability with the pharmacist's results. The mean cost of error detection per dose was $4.82 for direct observation and $0.63 for chart review. The technician was the least expensive observer at $2.87 per dose evaluated. R.N.s were the least expensive chart reviewers at $0.50 per dose. Of 457 errors, 35 (8%) were deemed potentially clinically significant; 71% of these were detected by direct observation. Direct observation was more efficient and accurate than reviewing charts and incident reports in detecting medication errors. Pharmacy technicians were more efficient and accurate than R.N.s and L.P.N.s in collecting data about medication errors.

Survey of primary care physicians and home care clinicians.

CONTEXT: Providing home care in the United States is expensive, and significant geographic variation exists in the utilization of these services. However, few data exist on how well physicians and home care providers communicate and coordinate care for patients. OBJECTIVE: To assess communication and collaboration between primary care physicians (PCPs) and home care clinicians (HCCs) within 1 primary care network. DESIGN: Mail survey. SETTING: Boston. PARTICIPANTS: Sixty-seven PCPs from 1 academic medical center-affiliated primary care network and 820 HCCs from 8 regional home care agencies. MEASUREMENTS: Provider responses RESULTS: Ninety percent of PCPs and 63% of HCCs responded. The majority (54%) of PCPs reported that they only "rarely" or "occasionally" read carefully the home care order forms sent to them for signature. Further, when asked to rate their prospective involvement in the decision making about home care, only 24% of PCPs and 25% of HCCs rated this as "excellent" or "very good." Although more HCCs (79%) than PCPs (47%) reported overall satisfaction with communication and collaboration, 28% of HCCs felt they provided more services to patients than clinically necessary. CONCLUSIONS: PCPs from 1 provider network and the HCCs with whom they coordinate home care were both dissatisfied with many aspects of communication and collaboration regarding home care services. Moreover, neither group felt in control of home care decision making. These findings are of concern because poor coordination of home care may adversely affect quality and contribute to inappropriate utilization of these services.

End of visit: design considerations for an ambulatory order entry module.

Current paper-based processes for performing billing documentation and test ordering at the end of a clinic visit are fraught with problems, resulting in numerous workflow inefficiencies and significant revenue losses for a healthcare organization. Paper forms are often filled out inaccurately or incompletely, or can be misrouted or lost. Computerizing these processes can alleviate many of these problems. We are building a new module for our ambulatory electronic medical record system to automate these "end of visit" (EOV) activities, which includes completing encounter forms, ordering lab and diagnostic tests, and printing patient visit summaries. An EOV module must be carefully designed to incorporate the needs of clinicians, front office staff, ancillary labs, medical records, and finance departments. An optimally designed EOV system should be customizable to fit into the clinician's workflow, and should help reduce financial losses, improve clinical documentation, and reduce workflow inefficiencies.

Detecting adverse events for patient safety research: a review of current methodologies.

Promoting patient safety is a national priority. To evaluate interventions for reducing medical errors and adverse event, effective methods for detecting such events are required. This paper reviews the current methodologies for detection of adverse events and discusses their relative advantages and limitations. It also presents a cognitive framework for error monitoring and detection. While manual chart review has been considered the "gold-standard" for identifying adverse events in many patient safety studies, this methodology is expensive and imperfect. Investigators have developed or are currently evaluating, several electronic methods that can detect adverse events using coded data, free-text clinical narratives, or a combination of techniques. Advances in these systems will greatly facilitate our ability to monitor adverse events and promote patient safety research. But these systems will perform optimally only if we improve our understanding of the fundamental nature of errors and the ways in which the human mind can naturally, but erroneously, contribute to the problems that we observe.

A tiered approach is more cost effective than traditional pharmacist-based review for classifying computer-detected signals as adverse drug events.

OBJECTIVE: To develop a cost-efficient method for identifying adverse drug events (ADEs) and medication errors (MEs) identified using outpatient electronic medical records within ambulatory settings. DESIGN: Comparison of sensitivity and cost of "traditional" pharmacist based approach to identifying ADEs and MEs during a 4 month period with a tiered approach. RESULTS: The proportion of computer generated signals analyzed identified as ADEs were similar using the two approaches while the number of MEs was nearly double with tiered reviews suggesting the same or better sensitivity. Traditional pharmacist review cost $68.70 US dollars to detect an ADE and tiered approach cost only $42.40. CONCLUSION: Tiered review of ADEs and MEs by personnel with increasing clinical capability is more cost-efficient than pharmacist review.

Design and implementation of a comprehensive outpatient Results Manager.

Prior research has demonstrated that clinicians often fail to review and act upon outpatient test results in a timely and appropriate manner. To address this patient safety and quality of care issue, Partners Healthcare has developed a browser-based, provider-centric, comprehensive results management application to help clinic physicians review and act upon test results in a safe, reliable, and efficient manner. The application, called the Results Manager, incorporates extensive decision support features to classify the degree of abnormality for each result, presents guidelines to help clinicians manage abnormal results, allows clinicians to generate result letters to patients with predefined, context-sensitive templates and prompts physicians to set reminders for future testing. In this paper, we outline the design process and functionality of Results Manager. We also discuss its underlying architectural design, which revolves around a clinical event monitor and a rules engine, and the methodological challenges encountered in designing this application.

Effective drug-allergy checking: methodological and operational issues.

Adverse drug events cause a large number of injuries, and adverse events caused by medications administered in the face of known allergies represent an important preventable cause of patient harm. Computerized systems can effectively prevent reactions due to known allergies, but building an effective allergy prevention feature is challenging and presents many interesting informatics issues that have both methodological and operational implications. In this paper, we present the experiences from one large delivery system in delivering allergy-related decision support, discuss some of the different approaches that we have used, and then propose a future approach. We also discuss the methodological, behavioral, and operational issues that have arisen which have a major impact on success. Key factors in drug-allergy checking include storing patient allergy data in a single common repository, representing allergy data using suitable terminologies and creating groups of allergies for inferencing purposes, being judicious about which allergy warnings to display, conveying the reaction that the patient has experienced when exposed to the drug to inform the provider of the importance of the warning, and perhaps most important, implementing strategies to optimize the likelihood that allergy information will be entered.

Communicating health information to an alarmed public facing a threat such as a bioterrorist attack.

Considerable literature exists on the communication of risk to the public through channels such as television, radio, and newspapers. However, little has been written on the communication of risk through less traditional communication forms, such as the Internet. The purpose of this study was to investigate the role of the Internet as an additional source of health information to that provided by the traditional news media in managing the public's response to an emerging health risk such as a bioterrorist attack. Despite some of the Internet's advantages over traditional media, including the depth and speed in which information can be conveyed to different audiences, the Internet was underutilized during fall 2001, when it became important to convey information on the risks of anthrax. A number of developments are required if the health care system is to capitalize on the Internet's potential as a risk communication device. These developments include research into public Internet searching behavior and further development in the role of search engines and government agencies in organizing quality health information.

Intravenous medication safety and smart infusion systems: lessons learned and future opportunities.

The Institute of Medicine report To Err Is Human: Building a Safe Health System greatly increased national awareness of the need to improve patient safety in general and medication safety in particular. Infusion-related errors are associated with the greatest risk of harm, and "smart" (computerized) infusion systems are currently available that can avert high-risk errors and provide previously unavailable data for continuous quality improvement (CQI) efforts. As healthcare organizations consider how to invest scarce dollars, infusion nurses have a key role to play in assessing need, evaluating technology, and selecting and implementing specific products. This article reviews the need to improve intravenous medication safety. It describes smart infusion systems and the results they have achieved. Finally, it details the lessons learned and the opportunities identified through the use of smart infusion technology at Brigham and Women's Hospital in Boston, Massachusetts.

Clinician use of a palmtop drug reference guide.

OBJECTIVE: Problems involving drug knowledge are one of the most common causes of serious medication errors. Although the information that clinicians need is often available somewhere, retrieving it expeditiously has been problematic. At the same time, clinicians are faced with an ever-expanding pharmacology knowledge base. Recently, point-of-care technology has become more widely available and more practical with the advent of handheld, or palmtop, computing. Therefore, the authors evaluated the clinical contribution of a drug database developed for the handheld computer. ePocrates Rx (formerly known as qRx; ePocrates, San Carlos, California) is a comprehensive drug information guide that is downloadable free from the Internet and designed for the Palm OS platform align="right". DESIGN: A seven-day online survey of 3,000 randomly selected ePocrates Rx users was conducted during March 2000. MEASUREMENTS: User technology experience, product evaluation and usage patterns, and the effects of the drug reference database on information-seeking behavior, practice efficiency, decision making, and patient care. RESULTS: The survey response rate was 32 percent (n=946). Physicians reported that ePocrates Rx saves time during information retrieval, is easily incorporated into their usual workflow, and improves drug-related decision making. They also felt that it reduced the rate of preventable adverse drug events. CONCLUSIONS: Self-reported perceptions by responding clinicians endorse improved access to drug information and improved practice efficiency associated with the use of handheld devices. The clinical and practical value of using these devices in clinical settings will clearly grow further as wireless communication becomes more ubiquitous and as more applications become available.

Real-time notification of laboratory data requested by users through alphanumeric pagers.

The authors developed a novel feature in their clinical information systems, which allows clinicians to request notification about laboratory results. Clinicians who are expecting a particular laboratory result for a particular patient can request a report of the result via an alphanumeric pager as soon as the result is filed into the patient database. This feature has gained popularity and is heavily used in both inpatient and outpatient settings, at a rate of about 2,300 times per month. This event-monitor-based feature illustrates one way that information technology can be applied to improve communication in health care.

Detecting adverse events using information technology.

CONTEXT: Although patient safety is a major problem, most health care organizations rely on spontaneous reporting, which detects only a small minority of adverse events. As a result, problems with safety have remained hidden. Chart review can detect adverse events in research settings, but it is too expensive for routine use. Information technology techniques can detect some adverse events in a timely and cost-effective way, in some cases early enough to prevent patient harm. OBJECTIVE: To review methodologies of detecting adverse events using information technology, reports of studies that used these techniques to detect adverse events, and study results for specific types of adverse events. DESIGN: Structured review. METHODOLOGY: English-language studies that reported using information technology to detect adverse events were identified using standard techniques. Only studies that contained original data were included. MAIN OUTCOME MEASURES: Adverse events, with specific focus on nosocomial infections, adverse drug events, and injurious falls. RESULTS: Tools such as event monitoring and natural language processing can inexpensively detect certain types of adverse events in clinical databases. These approaches already work well for some types of adverse events, including adverse drug events and nosocomial infections, and are in routine use in a few hospitals. In addition, it appears likely that these techniques will be adaptable in ways that allow detection of a broad array of adverse events, especially as more medical information becomes computerized. CONCLUSION: Computerized detection of adverse events will soon be practical on a widespread basis.

A proposal for electronic medical records in U.S. primary care.

Delivery of excellent primary care-central to overall medical care-demands that providers have the necessary information when they give care. This paper, developed by the National Alliance for Primary Care Informatics, a collaborative group sponsored by a number of primary care societies, argues that providers' and patients' information and decision support needs can be satisfied only if primary care providers use electronic medical records (EMRs). Although robust EMRs are now available, only about 5% of U.S. primary care providers use them. Recently, with only modest investments, Australia, New Zealand, and England have achieved major breakthroughs in implementing EMRs in primary care. Substantial benefits realizable through routine use of electronic medical records include improved quality, safety, and efficiency, along with increased ability to conduct education and research. Nevertheless, barriers to adoption exist and must be overcome. Implementing specific policies can accelerate utilization of EMRs in the U.S.

The use of computers for clinical care: a case series of advanced U.S. sites.

OBJECTIVE: To describe advanced clinical information systems in the context in which they have been implemented and are being used. DESIGN: Case series of five U.S. hospitals, including inpatient, ambulatory and emergency units. Descriptive study with data collected from interviews, observations, and document analysis. MEASUREMENTS: The use of computerized results, notes, orders, and event monitors and the type of decision support; data capture mechanisms and data form; impact on clinician satisfaction and clinical processes and outcomes; and the organizational factors associated with successful implementation. RESULTS: All sites have implemented a wide range of clinical information systems with extensive decision support. The systems had been well accepted by clinicians and have improved clinical processes. Successful implementation required leadership and long-term commitment, a focus on improving clinical processes, and gaining clinician involvement and maintaining productivity. CONCLUSION: Despite differences in approach there are many similarities between sites in the clinical information systems in use and the factors important to successful implementation. The experience of these sites may provide a valuable guide for others who are yet to start, or are just beginning, the implementation of clinical information systems.
