Effect of a multi-faceted rapid response system re-design on repeat calling of the rapid response team.

BACKGROUND: Repeat Rapid Response Team (RRT) calls are associated with increased in-hospital mortality risk and pose an organisation-level resource burden. Use of Non-Technical Skills (NTS) at calls has the potential to reduce potentially preventable repeat calling. NTS are usually improved through training, although this consumes time and financial resources. Re-designing the Rapid Response System (RRS) to promote use of NTS may provide a feasible alternative. METHODS: A pre-post observational study was undertaken to assess the effect of an RRS re-design that aimed to promote use of NTS during RRT calls. The primary outcome was the proportion of admissions each month subject to repeat RRT calling, and the average number of repeat calls per admission each month was the secondary outcome of interest. Univariate and multivariable interrupted time series analyses compared outcomes between the two study phases. RESULTS: The proportion of admissions with repeat calls each month increased across both phases of the study period, but the increase was lower in the post re-design phase (change in regression slope -0.12 (standard error 0.07) post versus pre re-design). The multivariable model predicted a 6% reduction (95% confidence interval -15.1-3.1; P = 0.19) in the proportion of admissions having repeat calls at the end of the post redesign phase study compared to the predicted proportion in the absence of the re-design. The average number of calls per admission was also predicted to decrease in the post re-design phase, with an estimated difference of -0.07 calls per admission (equivalent to one fewer repeat call per 14 patients who had RRT calls) at the end of the post re-design phase (95% confidence interval -0.23-0.08, P = 0.35). CONCLUSION: This study of an RRS re-design showed modest, but not statistically significant, reductions in the proportion of admissions with repeat calls and the mean number of repeat calls per admission. Given the economic and workforce capacity issues that all health care systems now face, even small improvements in the RRS may have lasting impact across the organisation. For the potential interest of RRS managers, this paper presents a pragmatic, low-cost initiative intended to enhance communication and cooperation at RRT calls.

Re-designing a rapid response system: effect on staff experiences and perceptions of rapid response team calls.

BACKGROUND: Rapid Response Team (RRT) calls are clinical crises. Clinical and time pressures can hinder effective liaison between staff who call the RRT ('users') and those responding as part of the RRT ('members'). Non-technical skills (NTS) training has been shown to improve communication and cooperation but requires time and financial resources that may not be available in acute care hospitals. Rapid Response System (RRS) re-design, aiming to promote use of NTS, may provide an alternative approach to improving interactions within RRTs and between members and users. METHODS: Re-design of an existing mature RRS was undertaken in a tertiary, metropolitan hospital incorporating the addition of: 1) regular RRT meetings 2) RRT role badges and 3) a structured member-to-user patient care responsibility "hand-off" process. To compare experiences and perceptions of calls, users and members were surveyed pre and post re-design. RESULTS: Post re-design there were improvements in members' understanding of RRT roles (P = 0.03) and responsibilities (P < 0.01), and recollection of introducing themselves to users (P = 0.02). For users, after the re-design, there were improvements in identification of the RRT leader (P < 0.01), and in the development of clinical plans for patients remaining on the ward at the end of an RRT call (P < 0.01). However, post-re-design, fewer users agreed that the structured hand-off was useful or that they should be involved in the process. Both members and users reported fewer experiences of conflict at RRT calls post-re-design (both P < 0.01). CONCLUSION: The RRS re-design yielded improvements in interactions between members in RRTs and between RRT members and users. However, some unintended consequences arose, particularly around user satisfaction with the structured hand-off. These findings suggest that refinement and improvement of the RRS is possible, but should be an ongoing iterative effort, ideally supported by staff training. TRIAL REGISTRATION: NCT01551160.

Modifications to predefined rapid response team calling criteria: prevalence, characteristics and associated outcomes.

OBJECTIVE: Standardised rapid response team (RRT) calling criteria may not be applicable to all patients, and thus, modifications of these criteria may be reasonable to prevent unnecessary calls. Little data are available regarding the efficacy or safety of modifying RRT calling criteria; therefore, this study aimed to detail the prevalence and characteristics of modifications to RRT call triggers and explore their relationship with patient outcomes. DESIGN AND OUTCOME MEASURES: A pilot retrospective cohort study within a convenience sample of patients attended by a hospital RRT between July and December 2014; rates of repeat RRT calling and in-hospital mortality were compared between patients with and without modifications to standard calling criteria. Secondary analyses examined four different types of modifications, narrowing or widening of existing physiological calling criteria, to observations without defined calling criteria, and others. All analyses were performed using multivariable regression. RESULTS: During the study period, 673 patients had RRT calls, of whom 620 (91.2%) had data available for analysis. The majority of study patients (393; 63.4%) had modifications documented. Patients with modifications were more likely to have repeat RRT calls (odds ratio [OR], 2.86; 95% CI, 1.69-4.85) and experience in-hospital mortality (OR, 2.16; 95% CI, 1.31-3.57) versus patients without modifications. In the secondary analyses, although all classes of modification had higher rates of repeat calling, none reached statistical significance. Mortality was associated with having modifications that were more conservative than the standard calling criteria (adjusted OR, 2.81; 95% CI, 1.31-6.08). CONCLUSION: Modifications to standard calling criteria were frequently made, but did not seem to prevent further RRT calls and were associated with increased mortality. These findings suggest that modifications should be made with caution.

Reasons for Repeat Rapid Response Team Calls, and Associations with In-Hospital Mortality.

BACKGROUND: Previous publications noted increased mortality risk in patients subject to repeat rapid response team (RRT) calls. These patients were examined as a homogenous group, but there may be many reasons for repeat calls. Those potentially preventable by the rapid response system have not been investigated. METHODS: In a retrospective cohort study, patients with potentially preventable repeat calls were classified into two categories: type 1 (patients who had a repeat call following an initial call that ended despite the patient still triggering RRT calling criteria [T1-PRC]) and type 2 (patients with a repeat call within 24 hours of an initial call and for the same reason [T2-PRC]). In-hospital mortality for these patients and for those with repeat calls for all other reasons (ORC) were compared to patients with only a single call during their admission (SC). RESULTS: Mortality occurred in 31 (43.7%) T1-PRC, 13 (15.1%) T2-PRC, 56 (28.9%) ORC, and 289 (13.9%) SC patients. Univariate odds ratios (ORs), in comparison to SC patients, were 4.81 (95% confidence interval [CI]: 2.96-7.81; p < 0.001), 1.10 (95% CI: 0.60-2.02; p = 0.75), and 2.52 (95% CI: 1.80-3.52; p < 0.001), respectively. Mortality effects persisted for the T1-PRC and ORC groups after adjustment for patient, admission, and initial call characteristics with ORs of 4.07 (95% CI: 2.36-7.01; p < 0.001) and 2.29 (95% CI: 1.57-3.34; p < 0.001), respectively. CONCLUSION: This study found that repeat calls following an initial call that ended with ongoing breach of predefined calling criteria were strongly associated with increased mortality. This highlights the risk to patients when the RRT leaves reversible clinical deterioration unresolved at the end of a call.

Participant perceptions of a rapid response team training course.

BACKGROUND: Rapid response team (RRT) responders would benefit from training, to ensure competent and efficient management of the deteriorating patient. DESIGN, SETTING AND PARTICIPANTS: We obtained delegate feedback on a pilot training course for RRTs, commissioned by the Australian and New Zealand Intensive Care Society (ANZICS), at the second ANZICS: The Deteriorating Patient Conference. METHODS: We surveyed participants on their perceptions of the course overall, and their perceptions of sessions containing presentations and videotaped and live demonstrations of simulated scenarios of patients whose conditions were deteriorating. RESULTS: The survey response rate was 64% (96 of 150 potential attendees). Responses were positive, with 79.8% of responses (912/1143) agreeing that the participants had learnt something new, that the course would increase their confidence and competence during RRT calls, and that it had assisted them as an educator. The course was well received overall, with the interactive and live demonstration components of the course garnering positive feedback in the comments section of surveys. CONCLUSIONS: There was unanimous agreement by participants for further development of a formalised RRT training course for responding to the deteriorating patient. Participants who were RRT educators also supported the development of an RRT train-the-trainer course.

Perceptions of interactions between staff members calling, and those responding to, rapid response team activations for patient deterioration.

Objectives The aim of the present study was to investigate experiences of staff interactions and non-technical skills (NTS) at rapid response team (RRT) calls, and their association with repeat RRT calls. Methods Mixed-methods surveys were conducted of RRT members and staff who activate the RRT (RRT users) for their perceptions and attitudes regarding the use of NTS during RRT calls. Responses within the survey were recorded as Likert items, ranked data and free comments. The latter were coded into nodes relating to one of four NTS domains: leadership, communication, cooperation and planning. Results Two hundred and ninety-seven (32%) RRT users and 79 (73.8%) RRT members provided responses. Of the RRT user respondents, 76.5% had activated the RRT at some point. Deficits in NTS at RRT calls were revealed, with 36.9% of users not feeling involved during RRT calls and 24.7% of members perceiving that users were disinterested. Unresolved user clinical concerns, or persistence of RRT calling criteria, were reasons cited by 37.6% and 23%, respectively, of RRT users for reactivating an RRT to the same patient. Despite recollections of conflict at previous RRT calls, 92% of users would still reactivate the RRT. The most common theme in the free comments related to deficiencies in cooperation (52.9%), communication (28.6%) and leadership (14.3%). Conclusions This survey of RRT users and members revealed problems with RRT users' and members' interactions at the time of an RRT call. Both users and members considered NTS to be important, but lacking. These findings support NTS training for RRT members and users. What is known about the topic? Previous surveying has related experiences of criticism and conflict between clinical staff at RRT activations. This leads to reluctance to call the RRT when indicated, with risks to patient safety, especially if subsequent RRT activation is necessary. Training in NTS has improved clinician interactions in simulated emergencies, but the exact role of NTS during RRT calls has not yet been established. What does this paper add? The present survey examined experienced clinicians' perceptions of the use of NTS at RRT calls and the effect on subsequent calling. A key finding was a disparity between perceptions of how RRT members interact with those activating the RRT (RRT users) and their performance of NTS. This was reflected with unresolved RRT user clinical concern at the time of a call. In turn, this affected RRT users' attitudes and intentions to reactivate the RRT. Formal handover was considered desirable by both RRT users and members. What are the implications for practitioners? The interface between the RRT and those who call the RRT is crucial. This survey shows that RRT users desire to be included in the management of the deteriorating patient and have their concerns addressed before completion of RRT attendance. Failure to do so results in repeat activations to the same patient, with the potential for adverse patient outcomes. Training to include NTS, especially around handover, for RRT members may address this issue and should be explored further.

Crisis resource management, simulation training and the medical emergency team.

Recently there has been increased focus on improved detection and management of deteriorating patients in Australian hospitals. Since the introduction of the medical emergency team (MET) model there has been an increased role for intensive care unit staff in responding to deterioration of patients in hospital wards. Review and management of MET patients differs from the traditional model of ward patient review, as ICU staff may not know the patient. Furthermore, assessment and intervention is often time-critical and must occur simultaneously. Finally, about 10% of MET patients require intensive care-level interventions to be commenced on the ward, and this requires participation of non-ICU-trained ward staff. • To date, the interventions performed by MET staff and approaches to training responders have been relatively under investigated, particularly in the Australian and New Zealand context. In this article we briefly review the principles of the MET and contend that activation of the MET by ward staff represents a response to a medical crisis. We then outline why MET intervention differs from traditional ward-based doctor-patient encounters, and emphasise the importance of non-technical skills during the MET response. Finally, we suggest ways in which the skills required for crisis resource management within the MET can be taught to ICU staff, and the potential benefits, barriers and difficulties associated with the delivery of such training in New Zealand and Australia.

Propofol infusion for the retrieval of the acutely psychotic patient.

Transporting acutely psychotic patients is hazardous because of the risks they present to themselves, escorting staff, and aircraft. Various strategies have been proposed, usually involving combinations of sedating drugs and physical restraint. Thus far, none guarantees safe retrieval while completely mitigating risks. This case proposes the use of propofol as an alternative to more traditionally used agents. An infusion facilitated the uneventful and safe retrieval of a patient who had demonstrated resistance and tolerance to other drugs. Discussion is also presented on the potential utility of propofol for the retrieval of acutely psychotic patients.

Extracorporeal membrane oxygenation (ECMO) reconsidered.

The role of extracorporeal membrane oxygenation (ECMO) in the treatment of the acute respiratory distress syndrome (ARDS) is controversial, notwithstanding the recent publication of the results of the CESAR (Conventional Ventilation or ECMO for Severe Adult Respiratory Failure) trial. Using Bayesian meta-analytic methods from three randomised controlled trials (RCTs) of ECMO in ARDS, we estimate the mortality odds ratio to be 0.78 (95% credible interval, 0.25-3.04), P (OR > 1) = 30%. Thus, a null effect of ECMO is not excluded and there appears only weak evidence of efficacy. We survey particular problems associated with the conduct of the "pragmatic" CESAR trial: composite endpoints, sample size estimation under uncertainty of baseline mortality rates, the generation of unbiased treatment comparisons, the impact of treatment non-compliance, and the uncertainty associated with cost-effectiveness and cost-utility analysis. We conclude that the CESAR trial is problematic in terms of both the clinical and economic outcomes, although observational series suggest plausible efficacy. We suggest that ECMO finds rationale as rescue therapy and that the current uncertainty of its role mandates a further RCT.

Fatal thrombosis with activated factor VII in a paediatric patient on extracorporeal membrane oxygenation.

Bleeding remains a potential complication for patients requiring extracorporeal life support systems. Recombinant activated factor VII (rFVIIa) is one of the drugs used in controlling bleeding. Its use is generally found to be safe. We report a paediatric patient who developed fatal thrombosis with the use of rFVIIa whilst on extracorporeal membrane oxygenation and discuss the possible factors that lead to fatal thrombosis.
