The Impact

ABSTRACT Objective: We sought to assess the impact of the integration of the new roles of primary health care nurse practitioners (NPs) and physician assistants (PAs) on patient flow, wait times and proportions of patients who left without being seen in 6 Ontario emergency departments (EDs). Methods: We performed a retrospective review of health records data on patient arrival time, time of initial assessment by a physician, time of discharge from the ED and discharge status. Results: Whether a PA or NP was directly involved in the care of patients or indirectly involved by being on duty, the wait times, lengths of stay and proportion of patients who left without being seen were significantly reduced. When a PA or NP were directly involved in patients' care, patients were 1.6 (95% confidence interval [CI] 1.3–2.1, p < 0.05) and 2.1 (95% CI 1.6–2.8, p < 0.05) times more likely to be seen within the wait time benchmarks, respectively. Lengths of stay were 30.3% (95% CI 21.6%–39.0%, p < 0.01) and 48.8% (95% CI 35.0%–62.7%, p < 0.01) lower when PAs and NPs, respectively, were involved. When PAs and NPs were not on duty, the proportion of patients who left without being seen were 44% (95% CI 31%–63%, p < 0.01) and 71% (95% CI 53%–96%, p < 0.05), respectively. Conclusion: The addition of PAs or NPs to the ED team can improve patient flow in medium-sized community hospital EDs. Given the ongoing shortage of physicians, use of alternative health care providers should be considered. These results require validation, as their generalizability to other locations or types of EDs is not known.

BackgroundRecent policy has encouraged emergency departments (EDs) to deploy nurses to stream patients from the ED front door to GPs working in a separate GP service operating within or alongside an ED. We aimed to describe mechanisms relating to effectiveness of streaming in different primary care service models identified in EDs. We explored perceptions of whether patients were perceived to be appropriately streamed to emergency care, primary care, other hospital services or community primary care services; and effects on patient flow (waiting times and length of stay in the ED); and safe streaming outcomes.MethodsWe used realist evaluation methodology to explore perceived streaming effectiveness. We visited 13 EDs with different primary care service models (purposively selected across England & Wales; 8 streamed primary care patients to a primary care clinician) and carried out observations of triage/streaming and patient flow and interviews with key members of staff (consultants, GPs, nurses). Field notes and audio-recorded interviews were transcribed and analysed by creating context, mechanism and outcome configurations to refine and develop theories relating to streaming effectiveness.ResultsWe identified five contexts (nurses’ knowledge and experience, streaming guidance, teamwork and communication, operational management and strategic management) that facilitated mechanisms that influenced the effectiveness of streaming (streaming to an appropriate service, patient flow, delivering safe care). We integrated a middle range psychological theory (cognitive continuum theory) with our findings to recommend a focus for training nurses in streaming and service improvements.ConclusionsWe identified key mechanisms relating to the effectiveness of primary care streaming in different models of service. We recommend a collaborative approach to service development, guidance and training (including input from ED clinicians and primary care clinicians) and a range of training strategies that are suitable for less experienced junior nurses and more experienced senior nurses and nurse practitioners.

Abstract Background This paper describes and compares patient flow characteristics of adult high system users (HSUs) and control groups in Alberta and Ontario emergency departments (EDs), Canada. Methods Annual cohorts of HSUs were created by identifying patients who made up the top 10% of ED users (by count of ED presentations) in the National Ambulatory Care Reporting System during 2011–2016. Random samples of patients not in the HSU groups were selected as controls. Presentation (e.g., acuity) and ED times (e.g., time to physician initial assessment [PIA], length of stay) data were extracted and described. The length of stay for 2015/2016 data was decomposed into stages and Cox models compared time between stages. Results There were 20,343,230 and 18,222,969 ED presentations made by 7,032,655 and 1,923,462 individuals in the control and HSU groups, respectively. The Ontario groups had higher acuity than the Alberta groups: about 20% in the Ontario groups were from the emergent level whereas Alberta had 11–15%. Time to PIA was similar across provinces and groups (medians of 60 min to 67 min). Lengths of stay were longest for Ontario HSUs (median = 3 h) and shortest for Alberta HSUs (median = 2.2 h). HSUs had shorter times to PIA (hazard ratio [HR] = 1.03; 95% confidence interval [CI] 1.02,1.03), longer times from PIA to decision (HR = 0.84; 95%CI 0.84,0.84), and longer times from decision to leaving the ED (HR = 0.91; 95%CI 0.91,0.91). Conclusions Ontario HSUs had higher acuity and longer ED lengths of stay than the other groups. In both provinces, HSU had shorter times to PIA and longer times after assessment.

Objectives: To identify effective facility design strategies to improve the performance of healthcare providers and patient flow during mass casualty incidents (MCIs) in emergency departments. Background: Emergency departments (EDs) are the first line of medical care in MCIs. While operational surge management plans are well described in literature, physical design strategies to improve performance and patient flow during disasters are discussed scarcely. Method: An online questionnaire was sent to EDs’ caregivers nationwide asking them to rate the effectiveness of nine physical design strategies, discussed in the literature, to improve caregivers’ performance and patient flow during MCIs. Assessed strategies were about providing expandable departments and care areas, alternate care facilities for the least sick to maximize care areas for critical patients, care areas from nonemergency units, increased number of decontamination units, dedicated isolation units, within-hospital and close emergency operation centers, and within-hospital media areas. Results: All suggested strategies were rated as effective. The most effective and agreed-upon solution was identified as maximizing the care area for critical patients by establishing an alternate care facility with separate entrance and exit doors from the emergency department for the least critical patients. The least effective and agreed-upon strategy was identified as locating a media unit within the hospital outside of the ED. Conclusions: Caregivers who work in EDs consider design strategies to be effective in surge management during disasters. Designers can consider implementing identified strategies in designing new emergency departments or expansion and renovation projects.
