Lean techniques for the improvement of patients' flow in emergency department

BACKGROUND: Emergency departments(EDs) face problems with overcrowding, access block, cost containment, and increasing demand from patients. In order to resolve these problems, there is rising interest to an approach called "lean" management. This study aims to(1) evaluate the current patient flow in ED,(2) to identify and eliminate the non-valued added process, and(3) to modify the existing process.METHODS: It was a quantitative, pre- and post-lean design study with a series of lean management work implemented to improve the admission and blood result waiting time. These included structured re-design process, priority admission triage(PAT) program, enhanced communication with medical department, and use of new high sensitivity troponin-T(hsTnT) blood test. Triage waiting time, consultation waiting time, blood result time, admission waiting time, total processing time and ED length of stay were compared.RESULTS: Among all the processes carried out in ED, the most time consuming processes were to wait for an admission bed(38.24 minutes; SD 66.35) and blood testing result(mean 52.73 minutes, SD 24.03). The triage waiting time and end waiting time for consultation were significantly decreased. The admission waiting time of emergency medical ward(EMW) was significantly decreased from 54.76 minutes to 24.45 minutes after implementation of PAT program(P<0.05).CONCLUSION: The application of lean management can improve the patient flow in ED. Acquiescence to the principle of lean is crucial to enhance high quality emergency care and patient satisfaction.

High-flow nasal cannula oxygen therapy during anesthesia recovery for older orthopedic surgery patients: A prospective randomized controlled trial

BACKGROUND Hypoxemia is a common complication in older patients during postoperative recovery and can cause pulmonary complications.Therefore,reducing the incidence of postoperative hypoxemia is a clinical concern.AIM To investigate the clinical efficacy of high-flow nasal cannula oxygen(HFNCO)in the resuscitation period of older orthopedic patients.METHODS In this prospective randomized controlled trial,60 older patients who underwent orthopedic surgery under general anesthesia were randomly divided into two groups:those who used conventional face mask and those who used HFNCO.All patients were treated with 60%oxygen for 1 h after extubation.Patients in the conventional face mask group were treated with a combination of air(2 L)and oxygen(2 L)using a traditional mask,whereas those in the HFNCO group were treated with HFNCO at a constant temperature of 34℃ and flow rate of 40 L/min.We assessed the effectiveness of oxygen therapy by monitoring the patients’arterial blood gas,peripheral oxygen saturation,and postoperative complications.RESULTS The characteristics of the patients were comparable between the groups.One hour after extubation,patients in HFNCO group had a significantly higher arterial partial pressure of oxygen(paO_(2))than that of patients in conventional face mask group(P<0.001).At extubation and 1 h after extubation,patients in both groups showed a significantly higher arterial partial pressure of carbon dioxide(paCO_(2))than the baseline levels(P<0.001).There were no differences in the saturation of peripheral oxygen,paO_(2),and paCO_(2) between the groups before anesthesia and before extubation(P>0.05).There were statistically significant differences in paO_(2) between the two groups before anesthesia and 1 h after extubation and immediately after extubation and 1 h after extubation(P<0.001).However,there were no significant differences in the oxygen tolerance score before leaving the room,airway humidification,and pulmonary complications 3 d after surgery between the two groups(P>0.05).CONCLUSION HFNCO can improve oxygen partial pressure and respiratory function in elderly patients undergoing orthopedic surgery under general endotracheal anesthesia.Thus,HFNCO can be used to prevent postoperative hypoxemia.

CEREBRAL BLOOD FLOW AND METABOLISM EVALUATION IN COMATOSE PATIENTS BY DYNAMIC SPECT

Thirty patients in coma state underwent dynamic SPECT with 133Xe, a validated technique for the quantitation of CBF by SPECT, using a new brain dedicated tomograph: CERTO-96. CMRO2 was computed by multiplying the mean CBF by AVDO2 according to the Fick’s principle. The mean values of CBF, AVDO2 and CMRO2 in patients with good outcome were significantly different from those with worse outcome. On the basis of the best "discriminant threshold", CBF and AVDO2 demonstrated an intermediate accuracy in separating the two groups, while CMRO2 showed a satisfactory accuracy.

Feedback of inter-hospital transfer of patients under high-flow nasal cannula oxygen therapy

Severe forms of coronavirus disease 2019 (COVID-19)can lead to hypoxemic pneumonia and the need for treatment with high-flow nasal cannula (HFNC) oxygen therapy.This treatment decreases the need for subsequent invasive ventilation in patients with hypoxemic pneumonia.The oxygen flow in the nasal cannula is driven pneumatically or using a turbine.Oxygen and air are mixed (giving the fraction of inspired oxygen[FiO;]) and propelled at up to 80L·min;.The propelled gases must be heated and humidified.HFNC system is not intended for use outside a hospital environment.

End-of-life home care of an interstitial pneumonia patient supported by high-flow nasal cannula therapy:A case report

BACKGROUND High-flow nasal cannula(HFNC)therapy and morphine continuous subcutaneous infusion(CSI)have been used to ameliorate dyspnea in non-cancer patients with end-stage respiratory diseases,including chronic obstructive pulmonary disease and interstitial pneumonia,primarily in hospital settings.However,it is rare to perform home-based medical treatment using these.We observe a case to assess the feasibility of this treatment strategy.CASE SUMMARY Here,we report a case of a 75-year-old man who was diagnosed with interstitial pneumonia 11 years ago and was successfully nursed at home during his terminal phase for over 10 mo without hospitalization,by introducing domiciliary uses of HFNC and morphine CSI with a patient-controlled analgesia device.CONCLUSION Active utilization of HFNC and morphine CSI with patient-controlled analgesia device would substantiate successful end-of-life palliative home care of idiopathic interstitial pneumonia patients.

Lessons learned from the TIMI trials in rescue interventions for elderly patients after failed fibrinolytic therapy:look beyond the TIMI flow

In ST-segment elevation myocardial infarction (STEMI), acute reperfusion of the infarct-related artery (IRA)is the main goal in the early minutes after the patient seeks medical attention. Fibrinolytic therapy (FT) and/or primary coronary intervention (PCI) were proven to be effective in opening the IRA.

Forecasting patient demand at urgent care clinics using explainable machine learning

Urgent care clinics and emergency departments around the world periodically suffer from extended wait times beyond patient expectations due to surges in patient flows.The delays arising from inadequate staffing levels during these periods have been linked with adverse clinical outcomes.Previous research into forecasting patient flows has mostly used statistical techniques.These studies have also predominately focussed on short‐term forecasts,which have limited practicality for the resourcing of medical personnel.This study joins an emerging body of work which seeks to explore the potential of machine learning algorithms to generate accurate forecasts of patient presentations.Our research uses datasets covering 10 years from two large urgent care clinics to develop long‐term patient flow forecasts up to one quarter ahead using a range of state‐of‐the‐art algo-rithms.A distinctive feature of this study is the use of eXplainable Artificial Intelligence(XAI)tools like Shapely and LIME that enable an in‐depth analysis of the behaviour of the models,which would otherwise be uninterpretable.These analysis tools enabled us to explore the ability of the models to adapt to the volatility in patient demand during the COVID‐19 pandemic lockdowns and to identify the most impactful variables,resulting in valuable insights into their performance.The results showed that a novel combination of advanced univariate models like Prophet as well as gradient boosting,into an ensemble,delivered the most accurate and consistent solutions on average.This approach generated improvements in the range of 16%-30%over the existing in‐house methods for esti-mating the daily patient flows 90 days ahead.

Experimental Investigation on Cavitating Flow Shedding over an Axisymmetric Blunt Body

Nowadays,most researchers focus on the cavity shedding mechanisms of unsteady cavitating flows over different objects,such as 2D/3D hydrofoils,venturi-type section,axisymmetric bodies with different headforms,and so on.But few of them pay attention to the differences of cavity shedding modality under different cavitation numbers in unsteady cavitating flows over the same object.In the present study,two kinds of shedding patterns are investigated experimentally.A high speed camera system is used to observe the cavitating flows over an axisymmetric blunt body and the velocity fields are measured by a particle image velocimetry（PIV）technique in a water tunnel for different cavitation conditions.The U-type cavitating vortex shedding is observed in unsteady cavitating flows.When the cavitation number is 0.7,there is a large scale cavity rolling up and shedding,which cause the instability and dramatic fluctuation of the flows,while at cavitation number of 0.6,the detached cavities can be conjunct with the attached part to induce the break-off behavior again at the tail of the attached cavity,as a result,the final shedding is in the form of small scale cavity and keeps a relatively steady flow field.It is also found that the interaction between the re-entrant flow and the attached cavity plays an important role in the unsteady cavity shedding modality.When the attached cavity scale is insufficient to overcome the re-entrant flow,it deserves the large cavity rolling up and shedding just as that at cavitation number of 0.7.Otherwise,the re-entrant flow is defeated by large enough cavity to induce the cavity-combined process and small scale cavity vortexes shedding just as that of the cavitation number of0.6.This research shows the details of two different cavity shedding modalities which is worthful and meaningful for the further study of unsteady cavitation.

Passive control of cavitating flow around an axisymmetric projectile by using a trip bar

Quasi-periodical evolutions such as shedding and collapsing of unsteady cloud cavitating flow, induce strong pressure fluctuations, what may deteriorate maneuvering stability and corrode surfaces of underwater vehicles. This paper analyzed effects on cavitation stability of a trip bar arranged on high-speed underwater projectile. Small scale water tank experiment and large eddy simulation using the open source software Open FOAM were used, and the results agree well with each other. Results also indicate that trip bar can obstruct downstream re-entrant jet and pressure wave propagation caused by collapse, resulting in a relatively stable sheet cavity between trip bar and shoulder of projectiles.

Effects of Micro Vibration Therapy Nursing Care on Muscle Hardness and Skin Blood Flow: A Pre/Post Group Comparison Study

Purpose: The purpose of this study was to investigate the effects of Micro Vibrational therapy (MVT) on muscle stiffness and blood flow in the skin before and after Micro Vibrational therapy in healthy subjects in order to scientifically verify the effects of MVT. Methods: Micro Vibrational therapy is nurse care use in Japan. It was performed on the backs of 30 subjects (8 males and 22 females) in their 20 s to 50 s according to the eligibility criteria. The resting state before implementation was set as the baseline for the control group, and after 30 seconds of MVT was set as the intervention group. The effects of the MVT were statistically analyzed by these factors and subjective sensation by Visual Analog Scale. Results: The muscle hardness of the area where the MVT was applied for 30 seconds decreased to 29.54 (SD 5.04) after the application, compared to 30.45 (SD 5.05) before. A corresponding t-test showed a significant difference (p = 0.019). Skin blood flow increased from a median of 0.76 (variance 0.062) before to a median of 0.86 (variance 0.16) after the procedure. The Wilcoxon rank test showed a significant difference (p = 0.000). Circulatory response was confirmed by SBP, DBP, and HR. SBP of 108.6 mmHg (SD 14.8) before the study decreased to 105.7 mmHg (SD 15.0) after the study, and DBP of 65.6 mmHg (SD 11.1) before the study decreased to 62.7 mmHg (SD 11.8) after the study. HR decreased from 71.6 beats per minute (SD 10.3) before to 69.2 beats per minute (SD 11.7) after. There was a significant difference in all cardiovascular indices (p < 0.05). VAS (pain, stiffness, and fatigue) was significantly decreased after MVT (p < 0.05). Conclusion: Micro Vibrational therapy tended to decrease muscle hardness and increase skin blood flow even in the short time of 30 seconds. The results suggest that local vibration stimulation is not likely to cause a sudden increase in blood pressure or pulse rate fluctuation. These results suggest that hand vibration nursing care may be applicable to acute patients with unstable circulatory conditions.
