Standardized measurement of the Modified Early Warning Score results in enhanced implementation of a Rapid Response System: A quasi-experimental study

Purpose

To study the effect of protocolized measurement (three times daily) of the Modified Early Warning Score (MEWS) versus measurement on indication on the degree of implementation of the Rapid Response System (RRS).

Methods

A quasi-experimental study was conducted in a University Hospital in Amsterdam between September and November 2011. Patients who were admitted for at least one overnight stay were included. Wards were randomized to measure the MEWS three times daily (“protocolized”) versus measuring the MEWS “when clinically indicated” in the control group. At the end of each month, for an entire seven-day week, all vital signs recorded for patients were registered. The outcomes were categorized into process measures including the degree of implementation and compliance to set monitoring standards and secondly, outcomes such as the degree of delay in physician notification and Rapid Response Team (RRT) activation in patients with raised MEWS (MEWS ≥ 3).

Results

MEWS calculations from vital signs occurred in 70% (2513/3585) on the protocolized wards versus 2% (65/3013) in the control group. Compliance with the protocolized regime was presents in 68% (819/1205), compliance in the control group was present in 4% (47/1232) of the measurements. There were 90 calls to primary physicians on the protocolized and 9 calls on the control wards. Additionally on protocolized wards, there were twice as much RRT calls per admission.

Conclusions

Vital signs and MEWS determination three times daily, results in better detection of physiological abnormalities and more reliable activations of the RRT.     

Rapid response teams,do not resuscitate orders,and potential opportunities to improve end-of-life care: a multicentre retrospective study

Purpose

Rapid response teams (RRTs) were created to stabilize acutely ill patients on the ward, but recent studies suggest that RRTs may improve end-of-life care (EOLC). To learn more about the role of the RRT in EOLC at our institutions, we conducted a retrospective review.

Methods

Retrospective review of 300 RRT consultations at 3 academic hospitals in Toronto, Canada.

Results

The typical consultation was for an elderly patient with chronic illness. More than 90% had a “full resuscitation” order at the time of consultation. One third were admitted to the intensive care unit within 48 hours of the RRT consultation, and 24.7% ultimately died. Twenty-seven (9.3%) had a patient/family conference on the ward within 48h of the RRT consultation, 24 (8.3%) of whom changed their resuscitation order as a result. Among those who changed their resuscitation order, fewer than 20% were referred to the palliative care or spiritual care service, or prescribed comfort medications as needed (pro re nata), within 48h of the RRT consultation; 2 patients died without receiving any common EOLC orders, and 15 (63%) died before discharge.

Conclusions

RRT consultation is an important milestone for many patients approaching EOL. RRTs frequently participate in EOL discussions and decision-making, but they may miss opportunities to facilitate EOLC.     

Rapid Response Team composition, resourcing and calling criteria in Australia

Introduction

Rapid Response Teams (RRTs) have been introduced into at least 60% of Intensive Care Unit (ICU) – equipped Australian hospitals to review deteriorating ward patients. Most studies have assessed their impact on patient outcome and less information exists on team composition or aspects of their calling criteria.

Methods

We obtained information on team composition, resourcing and details of activation criteria from 39 of 108 (36.1%) RRT-equipped Australian hospitals.

Results

We found that all 39 teams operated 24/7 (h/days), but only 10 (25.6%) had received additional funding for the service. Although 38/39 teams, were physician-led medical emergency teams, in 7 (17.9%) sites the most senior member would be unlikely to have advanced airway skills. Three quarters of calling criteria were structured into “ABCD”, and approximately 40% included cardiac and/or respiratory arrest as a calling criterion. Thresholds for calling criteria varied widely (particularly for respiratory rate and heart rate), as did the wording of the worried/concerned criterion. There was also wide variation in the number and nature of additional activation criteria.

Conclusions

Our findings imply the likelihood of significant practice variation in relation to RRT composition, staff skill set and activation criteria between hospitals. We recommend improved resourcing of RRTs, training of the team members, and consideration for improved standardisation of calling criteria across institutions.     

Toward Spanning the Quality Chasm: An Examination of Team Functioning Measures

Objective

To examine the effect of 5 measures of team functioning on patient outcomes.

Design

Observational, exploratory, measurement. Team functioning surveys and patient outcomes collected 1 year apart in a clinical trial were analyzed. The findings are discussed in context of the domains of team functioning, team effectiveness, and quality improvement.

Setting

27 Veterans Affairs medical centers.

Participants

Staff (t1: N=356; t2: N=273) on inpatient teams and patients (t1: N=4266; t2: N=3213) treated by the teams.

Interventions

Not applicable.

Main Outcome Measures

Five measures of team functioning (Physician Engagement, Shared Leadership, Supervisor Team Support, Teamness, and Team Effectiveness scales) and 3 measures of patient outcomes (functional improvement, discharge destination, and length of stay) were assessed at 2 time points with hierarchical generalized linear models to evaluate the association between team functioning measures and changes in patient outcomes.

Results

Associations (P<.05) between team functioning measures and patient outcomes were found for 3 of the 15 analyses over the study period. Higher Physician Engagement scale score was associated with lower length of stay (P=.017), and increased scores on Teamness and Team Effectiveness scales correlated with higher rates of community discharge (P=.044 and .049, respectively).

Conclusions

This exploratory analysis revealed trends that team functioning corresponds with patient outcomes in clinically relevant patterns. An increase in community discharge and a decrease in length of stay were associated with higher scores of team functioning. Here, we find evidence that modifiable attributes of team functioning have a measurable effect on patient outcomes. Such findings are promising and support the need for further research on team effectiveness.     

A systematic review of teamwork in the intensive care unit: What do we know about teamwork,team tasks,and improvement strategies?

Purpose

Teamwork is essential for ensuring the quality and safety of health care delivery in the intensive care unit (ICU). This article addresses what we know about teamwork, team tasks, and team improvement strategies in the ICU to identify the strengths and limitations of the existing knowledge base to guide future research.

Methods

A keyword search of the PubMed database was conducted in February 2013. Keyword combinations focused on 3 areas: (1) teamwork, (2) the ICU, and (3) training/quality improvement interventions. All studies that investigated teamwork, team tasks, or team interventions within the ICU (ie, intradepartment) were selected for inclusion.

Results

Teamwork has been investigated across an array of research contexts and task types. The terminology used to describe team factors varied considerably across studies. The most common team tasks involved strategy and goal formulation. Team training and structured protocols were the most widely implemented quality improvement strategies.

Conclusions

Team research is burgeoning in the ICU, yet low-hanging fruit remains that can further advance the science of teams in the ICU if addressed. Constructs must be defined, and theoretical frameworks should be referenced. The functional characteristics of tasks should also be reported to help determine the extent to which study results might generalize to other contexts of work.     

Response to a bolus of conivaptan in patients with acute hyponatremia after brain injury

Purpose

The aim of the study was to analyze the response to the vasopressin-receptor antagonist conivaptan in a large cohort of brain-injured patients with acute hyponatremia.

Materials and Methods

The natremic response (rise in serum sodium) to an initial bolus of conivaptan was retrospectively evaluated in 124 patients over a 3-year period in our neurosciences intensive care unit. Variables associated with this response were identified using linear regression.

Results

Median pretreatment sodium was 132 mEq/L, and duration of hyponatremia before dose was 1 day. Median natremic response was +4 mEq/L (interquartile range, 2-7 mEq/L), measured a median of 9 hours (interquartile range, 6-12 hours) after conivaptan administration. This was associated with significant urine output (median, 2.6 L over 12 hours), with degree of aquaresis associated with natremic response (regression coefficient, B = 1.8 change in sodium per liter; 95% confidence interval, 1.3-2.4; P < .001). Seventy-four patients (60%) responded with a rise of at least 4 mEq/L. Response was predicted by higher baseline urine output (B = 0.018 per mL; 0.004-0.032; P = .01) and lack of oral fluid intake (B = 2.06; 0.44-3.68; P = .01) but not tonicity of intravenous fluids or creatinine clearance.

Conclusions

Conivaptan given as a bolus can effectively treat acute hyponatremia in brain-injured patients.     

Human factors in resuscitation teaching

Introduction

There is an increasing interest in human factors within the healthcare environment reflecting the understanding of their impact on safety. The aim of this paper is to explore how human factors might be taught on resuscitation courses, and improve course outcomes in terms of improved mortality and morbidity for patients. The delivery of human factors training is important and this review explores the work that has been delivered already and areas for future research and teaching.

Method

Medline was searched using MESH terms Resuscitation as a Major concept and Patient or Leadership as core terms. The abstracts were read and 25 full length articles reviewed.

Results

Critical incident reporting has shown four recurring problems: lack of organisation at an arrest, lack of equipment, non functioning equipment, and obstructions preventing good care. Of these, the first relates directly to the concept of human factors. Team dynamics for both team membership and leadership, management of stress, conflict and the role of debriefing are highlighted. Possible strategies for teaching them are discussed.

Conclusions

Four strategies for improving human factors training are discussed: team dynamics (including team membership and leadership behaviour), the influence of stress, debriefing, and conflict within teams. This review illustrates how human factor training might be integrated further into life support training without jeopardising the core content and lengthening the courses.     

Regular in situ simulation training of paediatric Medical Emergency Team improves hospital response to deteriorating patients

Aim of the study

The introduction of a paediatric Medical Emergency Team (pMET) was accompanied by integration of weekly in situ simulation team training into routine clinical practice. On a rotational basis, all key ward staff participated in team training, which focused on recognition of the deteriorating child, teamwork and early consultant review of patients with evolving critical illness. This study aimed to evaluate the impact of regular team training on the hospital response to deteriorating in-patients and subsequent patient outcome.

Methods

Prospective cohort study of all deteriorating in-patients of a tertiary paediatric hospital requiring admission to paediatric intensive care (PICU) the year before, and after, the introduction of pMET and concurrent team training.

Results

Deteriorating patients were: recognised more promptly (before/after pMET: median time 4/1.5 h, p < 0.001), more often reviewed by consultants (45%/76%, p = 0.004), more often transferred to high dependency care (18%/37%, p = 0.021) and more rapidly escalated to intensive care (median time 10.5/5 h, p = 0.024). These improved responses by ward staff extended beyond direct involvement of pMET.There was a trend towards fewer PICU admissions, reduced level of sickness at the time of PICU admission, reduced length of PICU stay and reduced PICU mortality. Introduction of pMET coincided with significantly reduced hospital mortality (p < 0.001).

Conclusions

These results indicate that lessons learnt by ward staff during regular in situ team training led to significantly improved recognition and management of deteriorating in-patients with evolving critical illness. Integration of in situ simulation team training in clinical care has potential applications beyond paediatrics.     

The inability of emergency physicians to adequately clinically estimate the underlying hemodynamic profiles of acutely ill patients

Objective

Emergency physicians (EPs) estimate the underlying hemodynamics of acutely ill patients and use them to help both diagnose and formulate a treatment plan. This trial compared the EP clinically derived estimates of cardiac output (CO) and systemic vascular resistance (SVR) to those measured noninvasively.

Methods

Forty acutely ill emergency department patients with a broad range of diagnosis and blood pressure (BP) and pulse were monitored for 2 hours using novel noninvasive finger cuff technology (Nexfin; BMEYE, Amsterdam, The Netherlands). The Nexfin device provides continuous BP monitoring and, from the resulting pulse pressure waveform, calculates beat-to-beat CO and SVR. At baseline assessment and after 2 hours of testing and therapy, treating EPs were asked to estimate the CO and SVR (low, normal, or high), and these were compared with Nexfin measurements.

Results

Twenty-five men and 15 women were enrolled with a mean age of 62.2 years (SD, 12.6 years). Eighteen had acute shortness of breath; 11, with probable stroke syndrome; 3, with suspected sepsis; and 8, with a systolic BP greater than 180 or less than 100 mm Hg. Concordance tables showed that there was very little agreement (κ values) between either the compared initial CO (−0.0873) and SVR (−0.0645) or the 2-hour values (−0.0645 and −0.1949, respectively).

Conclusions

Emergency physicians cannot accurately estimate the underlying hemodynamic profiles of acutely ill patients when compared with more objective measurements. This inaccuracy may have important clinical ramifications. Further study is needed to determine how to use these measured continuous CO and SVR monitoring values.     

Nurse staffing,medical staffing and mortality in Intensive Care: An observational study

Objectives

To investigate whether the size of the workforce (nurses, doctors and support staff) has an impact on the survival chances of critically ill patients both in the intensive care unit (ICU) and in the hospital.

Background

Investigations of intensive care outcomes suggest that some of the variation in patient survival rates might be related to staffing levels and workload, but the evidence is still equivocal.

Data

Information about patients, including the outcome of care (whether the patient lived or died) came from the Intensive Care National Audit & Research Centre (ICNARC) Case Mix Programme. An Audit Commission survey of ICUs conducted in 1998 gave information about staffing levels. The merged dataset had information on 65 ICUs and 38,168 patients. This is currently the best available dataset for testing the relationship between staffing and outcomes in UK ICUs.

Design

A cross-sectional, retrospective, risk adjusted observational study.

Methods

Multivariable, multilevel logistic regression.

Outcome Measures

ICU and in-hospital mortality.

Results

After controlling for patient characteristics and workload we found that higher numbers of nurses per bed (odds ratio: 0.90, 95% confidence interval: [0.83, 0.97]) and higher numbers of consultants (0.85, [0.76, 0.95]) were associated with higher survival rates. Further exploration revealed that the number of nurses had the greatest impact on patients at high risk of death (0.98, [0.96, 0.99]) whereas the effect of medical staffing was unchanged across the range of patient acuity (1.00, [0.97, 1.03]). No relationship between patient outcomes and the number of support staff (administrative, clerical, technical and scientific staff) was found. Distinguishing between direct care and supernumerary nurses and restricting the analysis to patients who had been in the unit for more than 8 h made little difference to the results. Separate analysis of in-unit and in-hospital survival showed that the clinical workforce in intensive care had a greater impact on ICU mortality than on hospital mortality which gives the study additional credibility.

Conclusion

This study supports claims that the availability of medical and nursing staff is associated with the survival of critically ill patients and suggests that future studies should focus on the resources of the health care team. The results emphasise the urgent need for a prospective study of staffing levels and the organisation of care in ICUs.     

Depressive Symptoms in Women With Physical Disabilities: Identifying Correlates to Inform Practice

Objective

To examine correlates of depressive symptomatology in a sample of women with diverse physical disabilities to inform practice of modifiable risk factors that warrant attention and intervention.

Design

Interview survey.

Setting

Outpatient chronic care clinics.

Participants

Racially and ethnically diverse women (N=415) aged 18 to 64 years living with physical disabilities.

Interventions

Not applicable.

Main Outcome Measure

Center for Epidemiologic Studies Depression Scale.

Results

Depressive symptoms were high with more than half the women exceeding an established cutoff for clinically significant depressive symptomatology. In hierarchical multiple regression analyses, demographic, disability, and health variables explained significant variance in depressive symptoms; however, modifiable variables (pain interference, social support, abuse) contributed significantly to depression scores over and above demographic, disability, and health variables. Analyses examining predictors of depression classification revealed similar findings.

Conclusions

Depression is a significant problem for many women with physical disabilities. Modifiable contributors to depressive symptoms may provide intervention opportunities for researchers and clinicians. Clinicians need to attend closely to pain, particularly perceptions of pain interference; social support and social isolation; and abuse among women with physical disabilities. It may be valuable to include pain self-management, social networking and social skill development, and safety and abuse prevention training when designing depression intervention programs for this population.     

Use of an abnormal laboratory value-drug combination alert to detect drug-induced thrombocytopenia in critically Ill patients

Purpose

The aim of this study was to assess the performance of a commercially available clinical decision support system (CDSS) drug-laboratory result alert in detecting drug-induced thrombocytopenia in critically ill patients.

Materials and Methods

Adult patients admitted to the medical and cardiac intensive care unit during an 8-week period and identified by 1 of 3 signals in the CDSS, TheraDoc, were eligible. Alerts were generated when the patient had a low platelet count and was ordered a potentially causal drug. Patients were evaluated in real time for the occurrence of an adverse drug reaction using 3 causality instruments. Positive predictive values were calculated for the alert.

Results

Sixty-four patients with a mean age of 54 years met the inclusion criteria, generating 350 alerts. Positive predictive values were 0.36, 0.83, and 0.40 for signals 1, 2, and 3, respectively. Overall, there were 137 adverse drug reactions identified in the 350 alerts, with heparin, vancomycin, and famotidine as the 3 most common potential causes.

Conclusions

A commercial CDSS drug-laboratory alert is effective at identifying drug-induced thrombocytopenia in the intensive care unit and may improve patient safety. Compared with previous studies, the combination alert performs better than alerts based exclusively on laboratory values and should be considered to reduce alert fatigue.     

Impact of checklists on peri-intubation care in ED trauma patients

Background

Checklists have successfully been used in intensive care units (ICUs) to improve metrics of critical care. Proper peri-intubation care including use of appropriate induction agents and postintubation sedation is crucial when performing endotracheal intubation (ETI) on critically ill patients, especially in the emergency department (ED). We sought to evaluate the impact of checklists on peri-intubation care in ED trauma patients.

Methods

We performed a retrospective review of all trauma patients intubated in the ED of an urban, level 1 academic center from November 2010 to October 2012. As part of a quality improvement project, a peri-intubation checklist was instituted on November 1, 2011 to guide peri-intubation care.Using a predesign and postdesign, we compared peri-intubation parameters using parametric and nonparametric statistics when appropriate to evaluate the impact of a checklist on peri-intubation care.We also evaluated outcome measures including mortality and lengths of stay.

Results

During the 2-year study period, 187 trauma patients underwent ETI in the ED, 90 prechecklist and 97 postchecklist. Rapid sequence intubation (RSI) use was greater with the checklist than without (90.7% vs 75.6%, P = .005). No difference was found between the number of ETI attempts per patient, hemodynamic parameters (heart rate, blood pressure, and oxygen saturation), postintubation anxiolysis, median number of ventilator days, length of ED stay, length of ICU stay, or mortality.

Conclusion

Peri-intubation checklists result in higher rates of RSI in ED trauma patients but do not alter other measured metrics of peri-intubation care.     

Managing intensive care units: Make LOVE,not war!

Objective

Describe a program set up in a French intensive care unit (ICU) aimed at improving communication inside the team and communication information given to patients and their relatives; explain how those actions can improve communication inside the ICU and ultimately why it could improve patient's outcome.

Design and Methods

Position paper.

Intervention

Progressive implementation of multifaceted quality improvement program.

Results

The program Leadership, Ownership, Values, and Evaluation (LOVE) was developed over 10 years. It was usually well accepted by the members of the team, patients, and relatives, in particular the 24-hour visiting program that was prospectively evaluated. Information and decisions were shared with the patients or more often with the relatives, who became for some of them really “part of the team.” Additional actions such as participation to some of the simplest cares by the families are under investigation. A prospective evaluation of such programs, although difficult to perform, remains probably necessary.

Conclusion

Quality of life within the ICU is based on many factors including a strong and positive leadership, an absolute respect of individuals, and a rigorous evaluation of quality of care, which could influence heavily the quality of life in the ICU for patients, relatives, and health care professionals and facilitate team work. Whether this could really influence outcome remains to be demonstrated.     

Emergency Department Medication History Taking: Current Inefficiency and Potential for a Self-Administered Form

Background

Emergency Departments (EDs) struggle with obtaining accurate medication information from patients.

Objective

Our aim was to estimate the proportion of urban ED patients who are able to complete a self-administered medication form and record patient observations of the medication information process.

Methods

In this cross-sectional study, we consecutively sampled ED patients during various shifts between 8 am and 10 pm. We created a one-page medication questionnaire that included a list of 49 common medications, categorized by general indications. We asked patients to circle any medications they took and write the names of those not on the form in a dedicated area on the bottom of the page. After their visit, we asked patients to recall which providers had asked them about their medications.

Results

Research staff approached 354 patients; median age was 45 years (interquartile range 29–53 years). Two hundred and forty-nine (70%) completed a form, 61 (17%) were too ill, 19 (5%) could not read it, and 25 (7%) refused to participate. Excluding refusals, 249 of 329 (76%; 95% confidence interval 70–80%) were able to complete the form. Of 209 patients recalling their visit, 180 (86%) indicated that multiple providers took a history, including 103 in which every provider did so, and 9 (4%) indicated that no provider took a medication history.

Conclusions

The process of ED medication information transfer often involves redundant efforts by the health care team. More than 70% of patients presenting for Emergency care were able to complete a self-administered medication information form.     

Clinical evaluation compared to the pulse indicator continuous cardiac output system in the hemodynamic assessment of critically ill patients

Objective

The objective was to assess the effects of pulse indicator continuous cardiac output catheterization on the management of critically ill patients and the alteration of therapy in intensive care units.

Methods

One hundred thirty-two patients with primary physiological abnormalities of hypotension or hypoxemia were evaluated. Prior to catheterization, physicians were asked to complete a questionnaire that collected information regarding predictions of the ranges of several hemodynamic variables and plans for therapy. After catheterization, each chart was reviewed by a panel of intensive care attending physicians to determine the possibility of altering the therapy.

Results

Overall correct classification of the key variables ranged from 46.0% to 65.4%. Catheterization results prompted alterations in therapy for 45.5% of patients. The fellows were less accurate in predicting hemodynamic values for patients whose diagnoses were unknown, and the primary abnormality was hypotension. There was significant difference in the physicians’ abilities to predict the hemodynamics for the subgroups with and without acute myocardial infarction. When the patients were divided into 3 subgroups by Acute Physiology and Chronic Health Evaluation II and Sepsis-related Organ Failure Assessment scores, the fellows had the most difficulty predicting the variables of the moderately ill patients in the middle subgroup, which led to the greatest percentage of therapy alterations for this subgroup; and this difference was significant.

Conclusions

The hemodynamic variables obtained from pulse indicator continuous cardiac output catheterization improved the accuracy of bedside evaluations and led to alterations in therapeutic plans, particularly among the moderately ill patients with hypotension or unknown diagnoses.     

Effects of the hospital-based palliative care team on the care for cancer patients: An evaluation study

Background

The hospital-based palliative care team model has been implemented in most Western countries, but this model is new in Taiwan and there is little research to evaluate its outcomes.

Objectives

The purpose of this study was to evaluate the effects of the hospital-based palliative care team on the care for cancer patients.

Design

The design was a quasi-experimental study with a pretest–posttest design.

Setting

A medical center, National Taiwan University Hospital in Taipei, Taiwan.

Participants

Cancer patients were excluded after the hospital-based palliative care team visited if they were unable to give informed consent, were not well enough to finish the baseline assessment, were likely to die within 24 h or would be discharged within 24 h, or could not communicate in Mandarin or Taiwanese. A sample of 60 patients who consulted the hospital-based palliative care team was recruited.

Methods

Patients recruited to the study were divided to receive the usual care only (control group, n = 30) or the usual care plus visits from the hospital-based palliative care team (intervention group, n = 30). Data were collected using questionnaires including the Symptom Distress Scale, Hospital Anxiety and Depression Scale, Spiritual Well-Being Scale, and Social Support Scale at the initial assessment and one week later.

Results

Comparison between groups revealed that the degree change for edema, fatigue, dry mouth, abdominal distention, and spiritual well-being in the intervention group showed significant improvement compared to the control group (p < 0.05). However, there was no difference between groups on measures of anxiety, depression and feeling of social support. Within group analysis showed patients’ pain score, dyspnea, and dysphagia improved in both groups (p < 0.05). In addition, the average degree of constipation and insomnia in the control group declined from baseline (p < 0.05), while the degree of edema, fatigue, dry mouth, appetite loss, abdominal distention, and dizziness decreased significantly in the intervention group (p < 0.05).

Conclusion

The findings indicated the hospital-based palliative care team can improve the care for patients in relation to symptom management and spiritual well-being. The hospital-based palliative care team is a good care model for patients and worth implementing in clinical practice in Taiwan. The results also provide a general understanding about how the hospital-based palliative care team works in Taiwanese culture.     

Medical emergency team response for the non-hospitalized patient

Objectives

Rapid response systems (RRS) evolved to care for deteriorating hospitalized patients outside of the ICU. However, emergent critical care needs occur suddenly and unexpectedly throughout the hospital campus, including areas with non-hospitalized persons. The efficacy of RRS in this population has not yet been described or tested. We hypothesize that non-hospitalized patients accrue minimal benefit from ICU physician participation in the RRS.

Design

A retrospective review of all RRS events in non-hospitalized patients for a 28 month period was performed in a large, urban university medical center. Location, patient type and age, activation trigger, interventions performed, duration of event and disposition were recorded. Admission diagnosis and length of stay were also recorded for patients admitted to the hospital.

Setting

Academic medical center.

Patients

Non-hospitalized persons requiring evaluation by the medical emergency team.

Interventions

None.

Measurements and main results

There were a total of 1778 RRS activations during the study period. 232 (13%) of activations were for non-hospitalized patients. The patient cohort consisted of outpatients, visitors, and staff. Triggers for RRS activation were neurologic change (42%), cardiac (27%), respiratory (16%), and staff concerns (16%). The mean duration of the response was 38 min. The most common interventions performed included administration of oxygen (46%), intravenous fluids (13%) and dextrose (6%). 82% of patients were taken to the emergency department and 32% of the ED cohort were admitted to the hospital.

Conclusions

Perceived emergencies in non-hospitalized patients occur commonly but require minimal emergent intervention. Restriction of critical care physician involvement to inpatient deteriorations should be considered when designing a RRS. Future studies are needed to evaluate the utility of non-physician provider led rapid response teams with protocol-driven interventions for similar populations.     

Relationship between diurnal patterns in Rapid Response Call activation and patient outcome

Background

The Rapid Response Call (RRC) is a system designed to escalate care to a specialised team in response to the detection of patient deterioration. To date, there have been few studies which have explored the relationship between time of day of RRC and patient outcome.
