Introduction: The objective was to study the operational impact of an intervention comprised of simultaneous process improvements to triage, patient inflow, and physician scheduling patterns on emergency department (ED) patient flow. The intervention did not require any increase in ED resources or expenditures. Methods: A 36-month pre-/post-intervention retrospective chart review at an urban community emergency department from January 2010 to December 2012. The ED process improvements started on June 6, 2011 and involved streamlining triage, parallel processing, flexible nurse-patient ratios, flexible exam spaces, and flexible physician scheduling. The main outcomes were ED length-of-stay (LOS). Secondary outcomes included time to physician-initial-assessment (PIA), left-without-being-seen (LWBS) rates, and left-against-medical-advice (LAMA) rates. Segmented regression of interrupted time series analysis was performed on Canadian Triage and Acuity Scale (CTAS) 2 to 5 patients to quantify the immediate impact of the intervention on the outcome levels, and whether there were changes in the trend between pre-intervention and post-intervention segments. Results: 251,899 patients attended the ED during the study period. Daily patient volumes increased 17.3% during the post-intervention period. Post-intervention, for CTAS 2-5 patients, there was a reduction in average LOS by 0.64 hours (p<0.001), and 90th-percentile LOS by 0.81 hours (p=0.024). When separated by acuity and disposition, there were reductions in LOS for non-admitted CTAS 2 (-0.58 hours, p <0.001), 3 (-0.75 hours, p <0.001), 4 (-0.32 hours, p=0.002), and 5 (-0.28 hours, p=0.008) patients. For secondary outcomes, there was a decrease in overall average PIA by 43.81 minutes (p<0.001), and 90th-percentile PIA by 91.39 minutes (p<0.001). LWBS and LAMA rates decreased by 35.2% (p<0.001) and 61.9% (p<0.001), respectively. Conclusion: A series of process improvements meant to optimize flow in the ED without the addition of resources was associated with clinically significant reductions in LOS, PIA, LWBS and LAMA rates for non-resuscitative patients.

AbstractObjectiveTo study the operational impact of process improvements on emergency department (ED) patient flow. The changes did not require any increase in resources or expenditures.MethodsThis was a 36-month pre- and post-intervention study to evaluate the effect of implementing process improvements at a community ED from January 2010 to December 2012. The intervention comprised streamlining triage by having patients accepted into internal waiting areas immediately after triage. Within the ED, parallel processes unfolded, and there was no restriction on when registration occurred or which health care provider a patient saw first. Flexible nursing ratios allowed nursing staff to redeploy and move to areas of highest demand. Last, demand-based physician scheduling was implemented. The main outcome was length of stay (LOS). Secondary outcomes included time to physician initial assessment (PIA), left-without-being-seen (LWBS) rates, and left-against-medical-advice (LAMA) rates. Segmented regression of interrupted time series analysis was performed to quantify the impact of the intervention, and whether it was sustained.ResultsPatients totalling 251,899 attended the ED during the study period. Daily patient volumes increased 17.3% during the post-intervention period. Post-intervention, mean LOS decreased by 0.64 hours (p<0.005). LOS for non-admitted Canadian Triage and Acuity Scale 2 (-0.58 hours, p<0.005), 3 (-0.75 hours, p<0.005), and 4 (-0.32 hours, p<0.005) patients also decreased. There were reductions in PIA (43.81 minutes, p<0.005), LWBS (35.2%, p<0.005), and LAMA (61.9%, p<0.005).ConclusionA combination of process improvements in the ED was associated with clinically significant reductions in LOS, PIA, LWBS, and LAMA for non-resuscitative patients.

Abstract Background: Ischemic Cerebrovascular Accident (CVA) is the second cause of death and one of the leading causes of disability in the world. In Colombia, there is a prevalence of 0.16% and a mortality rate of 16.82 deaths per 100,000 inhabitants. This study assessed the Colombian Ministry of Health’s Emergency Department Triage Policy (TP) on the timeliness of hospital care, the mortality, and change in reperfusion therapy of patients with the first episode of an CVA in the Emergency Department (ED) of a hospital in the city of Medellín.Methods: A controlled interrupted time series analysis between January 2011 and November 2017 was performed in one emergency department using segmented regression analysis. The emergency department of other hospital was used as a control. Data were aggregated by month for both ED, including 60 pre-intervention and 23 intervention points.Results: No decrease in the timeliness of care in the ED was found in patients with a stroke after implementing the Colombian Ministry of Health’s TP (12.55 minutes, IC -17.07, 42.17; p: 0.4). The TP intervention produced a level change in the timeliness of care in Triage I and II subgroups, of 28.34 minutes (IC 95% 16.9, 39.79; p valor 0.00), there was no change in the trend. The classification of Triage I and II was more frequent in the post-intervention period. There was evidence of the increase in reperfusion therapy with tissue plasminogen activator (rTPA) in 4% (95% CI – 0.08, - 0.01; p value 0.01). Mortality increased 4% in the post-intervention period without being statistically significant (0.04, IC 95% - 0.08 – 0; p valor 0.06). There were no significant changes in the same outcomes in the control group.Conclusions: The implementation of the triage policy allowed improving the timeliness of ED care only in patients with ischemic CVA classified as Triage I and II, in an Emergency Department in the city of Medellín, Colombia.

Introduction: The Physician Navigator (PN) is a novel position created to manage patient flow in real-time at a very-high volume emergency department (ED). When paired with an emergency physician, PNs actively track patient wait times, and direct the physician to see and re-assess patients in a particular order to improve measures of emergency department efficiency, and maximize patient flow. Anecdotal evidence has shown that PNs decrease length-of-stay times for non-resuscitative patients in the setting of increased patient volumes, and without additional nursing or physician hours. The objective was to study the operational impact of PN on emergency department patient flow. Methods: A 48-month pre-/post-intervention retrospective chart review at an urban community emergency department from September 2011 to September 2015. The PN program started on March 1, 2013. The main outcome is emergency department length-of-stay (LOS). Secondary outcomes include time to physician-initial-assessment (PIA), left-without-being-seen rates (LWBS), left-against-medical-advice (LAMA), and physician satisfaction rates. Autoregressive integrated moving average models were generated for Canadian Triage and Acuity Scale (CTAS) 2 to 5 patients to quantify the immediate impact of the intervention on the outcome levels, and whether the impact was sustained over time. Results: Interim results are provided. 399,958 patients attended the ED during the study period. Daily patient volumes increased 11.2% during the post-intervention period. There were no significant increases in the number of physicians shifts/day, and physician hours/day during the post-intervention period. Post-intervention, for CTAS 2-5 patients, there was a reduction in average LOS by 0.04 hours/PN (p<0.05), and 90th-percentile LOS by 0.14 hours/PN (p<0.05). For secondary outcomes, there was a decrease in overall average PIA by 6.37 minutes/PN (p<0.05), and 90th-percentile PIA by 8.29 minutes/PN (p<0.05). LWBS rates decreased by 40.8% (p<0.05). There were no significant changes in LAMA rates. Conclusion: The implementation of Physician Navigators is associated with significant reductions in LOS, PIA, and LWBS rates for non-resuscitative patients at a very-high volume emergency department.

The Impact

Purpose: Assess the impact of 24/7/365 emergency trauma radiology (ETR) coverage on Emergency Department (ED) patient flow in an urban, quaternary-care teaching hospital. Methods: Patient ED visit and imaging information were extracted from the hospital patient care information system for 2008 to 2018. An interrupted time-series approach with a comparison group was used to study the impact of 24/7/365 ETR on average monthly ED length of stay (ED-LOS) and Emergency Physician to disposition time (EP-DISP). Linear regression models were fit with abrupt and permanent interrupts for 24/7/365 ETR, a coefficient for comparison series and a SARIMA error term; subgroup analyses were performed by patient arrival time, imaging type and chief complaint. Results: During the study period, there were 949,029 ED visits and 739,796 diagnostic tests. Following implementation of 24/7/365 coverage, we found a significant decrease in EP-DISP time for patients requiring only radiographs (-29 min;95%CI:-52,-6) and a significant increase in EP-DISP time for major trauma patients (46 min;95%CI:13,79). No significant change in patient throughput was observed during evening hours for any patient subgroup. For overnight patients, there was a reduction in EP-DISP for patients with symptoms consistent with stroke (-78 min;95%CI:-131,-24) and for high acuity patients who required imaging (-33 min;95%CI:-57,-10). Changes in ED-LOS followed a similar pattern. Conclusions: At our institution, 24/7/365 in-house ETR staff radiology coverage was associated with improved ED flow for patients requiring only radiographs and for overnight stroke and high acuity patients. Major trauma patients spent more time in the ED, perhaps reflecting the required multidisciplinary management.

Objective: The opioid epidemic is frequently discussed including the staggering numbers involved with coprescribing opioids and benzodiazepines associated with death. Community pharmacists, with the help of a system intervention, have a unique opportunity to help reduce the coprescribing of benzodiazepines and opioids and reduce the associated risk of death.Design: A single center retrospective chart review was conducted after a system intervention was placed, as a quality improvement project, from November 2019 to May 2020.Setting: Independent community pharmacy.Patients/participants: Data included demographics, dosing of each medication pre- and post-intervention, and naloxone status.Main outcome(s) measures: The primary outcome evaluated was reduction in dose/discontinuation of these prescriptions. The secondary outcome evaluated was the number of naloxone prescriptions ordered per protocol and picked up.Results: The primary outcome did not show statistical difference; however, the secondary outcomes showed statistical significance.Conclusion: In conclusion, community pharmacists, with the help of evolving technologies, can reduce harm associated with the coprescribing of benzodiazepines and opioids.

The Impact

Background/aims Despite epistaxis being a common presentation to emergency departments there is a lack of guidelines, both nationally and internationally, for its management. The authors reviewed the current management of epistaxis and then introduced a new pathway for management to see if care could be improved. The aims were to evaluate the impact of the pathway on reduction of emergency department breaches, emergency ambulance transfers and hospital admissions. Methods The study was an interrupted time series analysis over 29 months and included 903 participants. A pathway for the management of adults with non-traumatic epistaxis was designed and implemented in a university teaching hospital with an emergency department annual attendance rate of 105 495 in 2019–20. Results The pathway led to a 14-minute longer stay in the emergency department, a 5% increase in emergency department breaches, an 8.2% reduction in admissions, a 3.6% reduction in emergency ambulance transfers, a 14.1% increase in nasal cautery and a 3.2% reduction in nasal packing. Conclusions The authors calculate that these results equate to roughly 56 hospital bed days saved, providing better care closer to home for patients, in addition to beneficial knock-on effects for other emergency department and admitted patients.

ObjectiveTo investigate the association between the implementation of an integrated care (IC) system in Norrtälje municipality and changes in trends of the rate of emergency department (ED) visits.DesignInterrupted time series analysis from 2000 to 2015.SettingStockholm County.ParticipantsAll inhabitants 65+ years in Stockholm County on 31 December of each study year.InterventionIC was established by combining the funding, administration and delivery of health and social care for older persons in Norrtälje municipality, within Stockholm County.OutcomeRates of hospital-based ED visits.ResultsIC was associated with a decrease in the rate of ED visits (incidence rate ratio: 0.997, 95% CI 0.995 to 0.998) among inhabitants 65+ years in Norrtälje. However, the rate of ED visits remained higher in Norrtälje than the rest of Stockholm in the preintervention and postintervention periods. Stratified analyses showed that IC was associated with a decline in the trend of the rate of ED visits among those 65–79 years, the lowest income group and born outside of Sweden. However, there was no significant decrease in the trend among those 80+ years.ConclusionThe implementation of IC was associated with a modest change in the trend of ED visits in Norrtälje, though the rate of ED visits remained higher than in the rest of Stockholm. Changes in the composition of the population and contextual changes may have impacted our findings. Further research, using other outcome measures is needed to assess the impact of IC on healthcare utilisation.

Introduction: London Health Sciences Centre (LHSC) includes two academic, urban hospitals in London, Canada. The hospital-standardized mortality ratio (HSMR) is consistently higher than provincial and national averages. Unpublished data reveals that sepsis contributes the largest number of statistically unexpected deaths to LHSC’s HSMR calculation. Factors contributing to in-hospital sepsis mortality are hypothesized to include demography, emergency department (ED) flow or sepsis treatment. Methods: Retrospective chart review of patients aged &gt;=18 years, presenting to an LHSC ED between 01 Nov 2014 and 31 Oct 2015, with &gt;=2 SIRS criteria and/or ED suspicion of infection and/or ED or hospital discharge sepsis diagnosis (ICD-10 diagnostic codes A4xx and R65). Data were abstracted from electronic health records. Regional, provincial and national data was retrieved from CIHI and Statistics Canada. Results: Median age and sex in London and across Canada are similar (48.2 years vs 48.9 years; 48% male vs 49% male). Baseline prevalences of diabetes, hypertension, COPD and mood disorders were similar in the Local Health Integration Network and Ontario (6% vs 7%, 19% vs 19%, 3% vs 4%, and 10% vs 8%). Median “Physician Initial Assessment,” (PIA) times for sepsis patients at LHSC were faster than median Canadian PIA times for CTAS I and II patients (CTAS I: 7 min vs 11 min, CTAS II: 34 min vs 54 min), and slower for CTAS III-V patients (CTAS III: 98 min vs 79 min, CTAS IV: 99 min vs 66 min, CTAS V: 132 min vs 53 min). Median ED length of stay for admitted, high acuity (CTAS I-III) patients was 6 h at LHSC versus 10 h across Canada.Median [IQR] time to intravenous fluid resuscitation was 60.5 min [29.8-101.2] for septic shock patients and 77.0 min [36.0-127.0] for expired patients. Median [IQR] time to antibiotics was 130 min [73.0-229.0] for sepsis patients, 106 min [60.0-189.0] for severe sepsis patients, and 82 min [42.2-142] for septic shock patients. Conclusion: Excess sepsis-related mortality at LHSC is not convincingly related to patient demographics or ED flow. Gains may be made by improving time to antibiotics and IV fluids.

Abstract Background In Germany a new reimbursement system for psychiatric clinics was proposed in 2009 based on the § 17d KHG Psych-Entgeltsystem. The system can be voluntary implemented by clinics since 2013 but therapists are frequently afraid it might affect treatment negatively. Objectives To evaluate whether the new system has a negative impact on treatment success by analysing routinely collected data in a Bavarian clinic. Material and methods Aggregated data of 1760 patients treated in the years 2007–2016 was analysed with segmented regression analysis of interrupted time series to assess the effects of the system on treatment success, operationalized with three outcome variables. A negative change in level after a lag period was hypothesized. The robustness of results was tested by sensitivity analyses. Results The percentage of patients with treatment success tends to increase after the new system but no significant change in level was observed. The sensitivity analyses corroborate results for 2 outcomes but when the intervention point was shifted, the positive change in level for the third outcome became significant. Conclusions Our initial hypothesis is not supported. However, the sensitivity analyses disclosed uncertainties and our study has limitations, such as a short observation time post intervention. Results are not generalizable as data of a single clinic was analysed. Nevertheless, we show the importance of collecting and analysing routine data to assess the impact of policy changes on patient outcomes.
