Emergency department overcrowding: analysis of the factors of renege rate.

BACKGROUND: Reneging (i.e., leaving without being seen) is an important outcome of emergency department (ED) overcrowding. The input-throughput-output conceptualization of ED patient flow is helpful in understanding and measuring the impact of various factors on this outcome. OBJECTIVES: To quantify the impact of input and output factors on ED renege rate. METHODS: The authors used patient-level and system-level data from multiple sources in their institution to build logistic regression models, with reneging as the dependent variable. This approach provides the impact of each input and output factor on renege rate expressed as an odds ratio (OR). RESULTS: The OR for reneging attributable to the difference between the 80th and 20th percentile values for inpatient bed utilization is 1.05. Comparing 80th and 20th percentile values for boarded ED admits as of 7 AM, the OR is 1.73; for daily ED arrivals, the OR is 2.00; and for admission percentage, the OR is 1.12. The OR for evening versus morning patient arrival time is 3.9 and for patient arrival on a Monday versus a Sunday is 2.7. The OR for reneging for a patient presenting on Monday evening versus Sunday morning is 10.5. CONCLUSIONS: The effects of ED input and output factors on renege rate are significant and quantifiable. At least some of the variation in these factors and subsequently their effects are predictable, suggesting that further refinement in the management of ED and inpatient resources could affect improvement in ED renege rate. Continued efforts at quantifying the effects are warranted.

Embedded guideline information without patient specificity in a commercial emergency department computerized order-entry system.

BACKGROUND: Clinical practice guidelines and computerized provider order entry (CPOE) have potential for improving clinical care. Questions remain about feasibility and effectiveness of CPOE in the emergency department (ED). However, successful implementations in other settings typically incorporate decision support functions that are lacking in many commercially available ED information systems. OBJECTIVES: To compare acute coronary syndrome (ACS) guideline compliance before and after implementation of a locally implemented ACS guideline, first on paper and then in a commercially available ED information system without patient-specific clinical decision support. METHODS: Clinical data were abstracted retrospectively on patients seen before and after introduction of paper and, subsequently, CPOE versions of ACS guideline-based order-sets. Order-set use was determined. Risk category assignments were made retrospectively using guideline criteria and compliance with the guideline regarding beta-blockers, heparin, and aspirin was determined. Association between order-set use and compliance was determined. RESULTS: The authors found increasing use of order-sets over the period of study. However, there was poor association between the order-sets used and risk stratification category. Some association between ED beta-blocker use and use of CPOE order-sets was found, but there was no improvement in overall compliance with any of the guideline recommendations. CONCLUSIONS: Adherence to an ACS guideline did not improve with implementation of a commercial ED information system without provision for patient-specific decision support. This suggests that the lack of patient-specific decision-support functionality in most current ED information system products may hamper progress in the development of effective decision support.

Effects of implementing computerized practitioner order entry and nursing documentation on nursing workflow in an emergency department.

Nurses'perceptions of effective use of their time are critical to the successful implementation of information system changes. We examined the effects of implementing computerized practitioner order entry and nursing documentation in our emergency department with an anonymous survey of nurses and repeated time-motion studies. Emergency care nurses were positive about effects of CPOE, reporting needing less time to complete medication, laboratory, and radiology orders and less time spent clarifying orders. Their perceptions of time spent were congruent with observations from time-motion studies where combined computer-and-paper time and direct-patient-care time did not change significantly. Nurses also reported supplementing template options with free text, and those who were more comfortable using computers reported supplementing template options more often than their counterparts, suggesting that assessments of users' expertise in computer use may influence their ability to maximize their use of the functionality of emergency department information systems.

Physician perspective on computerized order-sets with embedded guideline information in a commercial emergency department information system.

Computerized provider order entry (CPOE) is a promising conduit for medical knowledge in support of guideline-consistent decision-making at the point of care. While there are many published examples of successful implementations of CPOE with decision support, there remain questions about the effectiveness of commercially available information system products, particularly in the emergency department (ED). We describe an attempt at using the available CPOE functionality in a commercial ED information system to deliver guideline knowledge and report the results of physician surveys regarding paper-based guideline/order-sets and the corresponding CPOE order-sets that replaced them. Physicians reported that they liked the CPOE order-sets better than the paper version and did use the order-sets, but guide-line compliance did not improve. Cultural and organizational issues as well as limitations in the functionality of the commercial system appear to have limited the effectiveness of this implementation.

Handheld computer application for time-motion studies in the emergency department.

Urban academic emergency departments face significant challenges of increasing patient volumes and sicker patients. Better understanding of the timing and interactions between provider activities may assist in efforts directed toward improving patient-care processes to decrease length of stay. Rapidly chang-ing and overlapping activities in the emergency department make time-motion study difficult. This poster describes a handheld computer application that enables synchronized capture of task description and times across multiple patient care providers in the emergency department.
