Impact of an Electronic Decision-Support System on Nursing Triage Process: A Usability and Workflow Analysis.

PURPOSE: To qualitatively contrast emergency department triage workflow using a paper-based triage system and an electronic decision-support tool (electronic Canadian Triage and Acuity Scale (eCTAS)). METHODS: Triage nurses from a single institution were invited to perform triage assessments of mock patients using a paper-based triage system and eCTAS. These assessments were completed using simulation scenarios, some of which involved facilitators probing triage nurses' thoughts on the design of the eCTAS system. Participants were asked to "think aloud," describing their thought patterns as they completed the triage process. Similar patient scenarios with the same Canadian Emergency Department Information System (CEDIS) presenting complaint and triage score were used for comparison between paper-based triage and electronic decision-support tool (eCTAS) conditions. RESULTS: Eight participants completed at least two simulation scenarios for each condition and at least one usability scenario with eCTAS. The simulated encounters showed eCTAS provided several advantages to paper-based triage assessment process by shortlisting possible CEDIS complaints and preselecting relevant modifiers. However, usability concerns were identified with eCTAS including challenges related to data entry and eCTAS score overrides. CONCLUSIONS: Our study highlights several positive features of eCTAS and usability issues that should be addressed to enhance the intended use of eCTAS and support user adoption.

Introduction of Group Electronic Monitoring of Hand Hygiene on Inpatient Units: A Multicenter Cluster Randomized Quality Improvement Study.

BACKGROUND: The current approach to measuring hand hygiene (HH) relies on human auditors who capture <1% of HH opportunities and rapidly become recognized by staff, resulting in inflation in performance. Group electronic monitoring is a validated method of measuring HH adherence, but data demonstrating the clinical impact of this technology are lacking. METHODS: A stepped-wedge cluster randomized quality improvement study was performed on 26 inpatient medical and surgical units across 5 acute care hospitals in Ontario, Canada. The intervention involved daily HH reporting as measured by group electronic monitoring to guide unit-led improvement strategies. The primary outcome was monthly HH adherence (percentage) between baseline and intervention. Secondary outcomes included transmission of antibiotic-resistant organisms such as methicillin-resistant Staphylococcus aureus (MRSA) and other healthcare-associated infections. RESULTS: After adjusting for the correlation within inpatient units and hospitals, there was a significant overall improvement in HH adherence associated with the intervention (incidence rate ratio [IRR], 1.73 [95% confidence interval {CI}, 1.47-1.99]; P < .0001). Monthly HH adherence relative to the intervention increased from 29% (1 395 450/4 544 144) to 37% (598 035/1 536 643) within 1 month, followed by consecutive incremental increases up to 53% (804 108/1 515 537) by 10 months (P < .0001). There was a trend toward reduced healthcare-associated transmission of MRSA (IRR, 0.74 [95% CI, .53-1.04]; P = .08). CONCLUSIONS: The introduction of a system for group electronic monitoring led to rapid, significant improvements in HH performance within a 2-year period. This method offers significant advantages over direct observation for measurement and improvement of HH.

Prevention of respiratory outbreaks in the rehabilitation setting.

BACKGROUND: Respiratory viral (RV) outbreaks in rehabilitation facilities can jeopardise patient safety, interfere with patient rehabilitation goals and cause unit closures that impede patient flow in referring facilities. PROBLEM: Despite education about infection prevention practices, frequent RV outbreaks were declared each year at our rehabilitation facility. METHODS: Before and after study design. The primary outcome was the number of bed closure days due to outbreak per overall bed days. Process measures included delays in initiation of transmission-based precautions, RV testing and reporting of staff to occupational health and safety (OHS). Balancing measures included the number of isolation days and staff missed work hours. INTERVENTIONS: Based on comprehensive analysis of prior outbreaks, the following changes were implemented: (1) clear criteria for initiation of transmission-based precautions, (2) communication to visitors to avoid visitation if infectious symptoms were present, (3) exemption of staff absences if documented due to infectious illness, (4) development of an electronic programme providing guidance to staff about whether they should be excluded from work due to infectious illness. RESULTS: The number of bed closure days due to outbreak per overall bed days dropped from 2.8% to 0.5% during the intervention season and sustained at 0.6% during the postintervention season (p<0.001). There were fewer delays in initiation of droplet and contact precautions (28.8% to 15.5%, p=0.005) and collection of RV testing (42.9% to 20.3%, p<0.001), better reporting to OHS (9 vs 28.8 reports per 100 employees; p<0.001) and fewer isolation days (7.8% vs 7.3%; p=0.02) without a significant increase in missed work hours per 100 hours worked (4.0 vs 3.9; p=0.12). CONCLUSION: This Quality Improvement study highlights the process changes that can prevent respiratory outbreaks in the rehabilitation setting.
