The frequency and nature of barriers to escalation of care in two Australian teaching hospitals.

BACKGROUND: Nurses and junior doctors are often the first clinicians to recognise signs of deterioration in patients. However, there can be barriers to having conversations about escalation of care. OBJECTIVES: The aim of this study was to study the frequency and nature of barriers encountered during discussions related to escalation of care for deteriorating hospitalised patients. METHODS: This was a prospective observational study with daily experience sampling surveys related to escalation of care discussions. The study setting involved two teaching hospitals in Victoria, Australia. Consented doctors, nurses, and allied health staff members involved in routine care of adult ward patients participated in the study. The main outcome measures included the frequency of escalation conversations and the frequency and nature of barriers encountered during such conversations. RESULTS/FINDINGS: 31 clinicians participated in the study and completed an experience sampling survey 294 times, mean (standard deviation) = 9.48 (5.82). On 166 (56.6%) days, staff members were on clinical duties, and escalation of care discussions occurred on 67 of 166 (40.4%) of these days. Barriers to escalation of care occurred in 25 of 67 (37.3%) of discussions and most frequently involved lack of staff availability (14.9%), perceived stress in the contacted staff member (14.9%), perceptions of criticism (9.0%), being dismissed (7.5%), or indication of lack of clinical appropriateness in the response (6.0%). CONCLUSIONS: Discussions related to escalation of care by ward clinicians occur in almost half of clinical days and are associated with barriers in one-third of discussions. Interventions are needed to clarify roles and responsibilities and outline behavioural expectations on both sides of the conversation and enable respectful communication amongst individuals involved in discussions of escalation of patient care.

Frequency and nature of medical emergency team afferent limb failure in patients with documented vital sign abnormalities: A retrospective point prevalence study.

BACKGROUND: Medical emergency team (MET) afferent limb failure is the presence of MET triggers and the absence of a documented MET call. OBJECTIVES: The aim of this study was to measure and understand the frequency and nature of MET afferent limb failure in patients with documented vital sign abnormalities in an Australian major teaching hospital. METHODS: A retrospective point prevalence study was conducted at a 600-bed teaching hospital in Melbourne, Australia. Data were collected for all adult inpatients (aged ≥18 years) on 13 wards (three general medicine, three surgical, and seven specialist wards) during a randomly selected 24-h period. Data were extracted from the electronic medical record. RESULTS: There were 357 patients included in the study, with a median age of 72 y. Of the 9716 vital sign measures extracted, 0.9% fulfilled patient-specific MET activation criteria. There were 93 MET triggers documented in 36 patients: 25 patients experienced MET afferent limb failure. The major issues related to MET afferent limb failure were MET trigger modification processes, resolution of vital sign abnormalities, alternative escalation of care, and limitations of medical treatment orders without specific modifications to MET triggers. CONCLUSIONS: Mandating MET activation for one aberrant vital sign at a single point in time warrants further assessment: lack of timely vital sign resolution may be a more appropriate trigger for MET calls and should be formally tested in future research. The frequency and effectiveness of alternative escalation pathways and local management of patients with MET triggers also warrant further investigation.

Clinical documentation requirements for the accurate coding of hospital-acquired urinary tract infections in Australia.

Aims We evaluated the accuracy of medical coders in distinguishing the aetiology of urinary tract infection according to clinical documentation. Methods The clinical documentation of patients coded as having had a hospital-acquired urinary tract infection from January to June 2020 at two Melbourne hospitals were assessed for community or hospital acquisition. Results We found that 48.89% of cases were inaccurately categorised as hospital-acquired, due to insufficient detail in clinical documentation. Risk factors for hospital-acquired urinary tract infection were present in at least 30% of correctly categorised cases. Conclusions Clinical documentation is not filled out with sufficient detail or in a timely enough manner for clinical coders to distinguish between hospital or community origin.

Post resuscitation management of cardiac arrest patients in the critical care environment: A retrospective audit of compliance with evidence based guidelines.

BACKGROUND: There is a clear relationship between evidence-based post resuscitation care and survival and functional status at hospital discharge. The Australian Resuscitation Council (ARC) recommends protocol driven care to enhance chance of survival following cardiac arrest. Healthcare providers have an obligation to ensure protocol driven post resuscitation care is timely and evidence based. OBJECTIVES: The aim of this study was to examine adherence to best practice guidelines for post resuscitation care in the first 24h from Return of Spontaneous Circulation for patients admitted to the intensive care unit from the emergency department having suffered out of hospital or emergency department cardiac arrest and survived initial resuscitation. METHOD: A retrospective audit of medical records of patients who met the criteria for survivors of cardiac arrest was conducted at two health services in Melbourne, Australia. Criteria audited were: primary cardiac arrest characteristics, oxygenation and ventilation management, cardiovascular care, neurological care and patient outcomes. FINDINGS: The four major findings were: (i) use of fraction of inspired oxygen (FiO2) of 1.0 and hyperoxia was common during the first 24h of post resuscitation management, (ii) there was variability in cardiac care, with timely 12 lead Electrocardiograph and majority of patients achieving systolic blood pressure (SBP) greater than 100mmHg, but delays in transfer to cardiac catheterisation laboratory, (iii) neurological care was suboptimal with a high incidence of hyperglycaemia and failure to provide therapeutic hypothermia in almost 50% of patients and (iv) there was an association between in-hospital mortality and specific elements of post resuscitation care during the first 24h of hospital admission. CONCLUSION: Evidence-based context-specific guidelines for post resuscitation care that span the whole patient journey are needed. Reliance on national guidelines does not necessarily translate to evidence based care at a local level, so strategies to ensure effective guideline implementation are urgently required.

A national survey of Australian Intensive Care Unit (ICU) Liaison Nurse (LN) services.

BACKGROUND: The Intensive Care Unit (ICU) Liaison Nurses (LNs) emerged as a member of the multidisciplinary team to: assist in the transition of patients from ICU to the ward, respond to the deteriorating patient in an appropriate and timely manner, and in some instances act as an integral member of Rapid Response Teams (RRT). PURPOSE: To identify the common core aspects and diversity within the ICU LN role across Australia and to determine whether the ICU LN hours of operation and the participation in MET teams has any impact on the activities undertaken by the ICU LN. METHOD: This descriptive survey of 152 Australian ICUs was conducted in April 2010. The Advanced Practice Nurse (APN) framework was used to develop the survey instrument, which comprised of four scales, education (5 items), collaboration (6 items), practice (8 items) research and quality (6 items) and a number of demographic questions. Descriptive statistics (mean, standard deviation (SD), median, interquartile ranges (IQR) and frequency) were used to summarise the data. Student's t-tests and Pearson's correlations were used to test the hypotheses. RESULTS: Surveys were received from 113 hospitals (55 metropolitan, 58 regional): a 74% response rate. ICU LN services operated in 31 (27%) of these hospitals. LN services tended to operate in larger hospitals with higher ICU admission rates. The median weekly hours of operation was 56 (IQR 30; range 7-157), delivered by a median of 1.4 (IQR 0.9; range 0.0-4.2) Full Time Equivalent (FTE) staff. The median weekly patient visits made by the LN was 25 (IQR 44; range 2-145). The LN was reported to be a member of the Medical Emergency Team (MET) in 17 (68%) of the 25 hospitals that provided both MET and ICU LN services. The ICU LN activities were grouped under four key Advanced Practice Nurse (APN) domains: education, collaboration, practice and research/quality. Mean scale scores were calculated for each APN domain. The ICU LN reported being involved in activities associated with all four APN domains, and more frequently they were involved in education and expert practice during their daily work. Neither the presence of a MET nor the weekly operational hours of the LN service significantly affected the key activities undertaken by ICU LNs (education, collaboration, practice, research and quality). CONCLUSION: Whilst many hospitals across Australia have introduced an ICU LN service, the staffing, hours of service, job classifications, reporting lines, referral processes and APN activities undertaken by the ICU LN, vary between hospitals, highlighting the diverse nature of ICU LN services across Australia.

The impact of an ICU liaison nurse service on patient outcomes.

OBJECTIVE: To determine the effect an intensive care unit liaison nurse service had on ICU patient discharges, readmissions and outcomes. METHODS: We evaluated the impact of our ICU liaison nurse service in a 36-month before-and-after study on ICU and hospital length of stay (LOS) and mortality, and ICU step-down days (time spent in ICU in a 1 : 2 nurse to patient ratio). RESULTS: There was a 13% increase in patient throughput after the introduction of the ICU liaison nurse service (835 ICU admissions in the 18 months before v 943 in the 18 months after). Despite trends to an improvement, there was no significant change in median ICU LOS (2.2 days before v 2.1 days after) or median hospital LOS (12.0 days before v 11.5 days after), or in ICU or hospital mortality (ICU, 15% before v 14% after; hospital, 23% before v 22% after). ICU step-down days were significantly decreased by 48% (71 +/- 14.2 days v 37 +/- 15.5 days; P < 0.001). In the patient group readmitted to the ICU (49 patients before v 55 patients after), there was a 25% (1 day) decrease in median ICU LOS (4.0 v 3.0 days), and a trend to decreased mortality in both the ICU (18% before v 16% after) and hospital (35% before v 26% after). CONCLUSIONS: The introduction of our ICU liaison nurse service was associated with a trend towards more efficient ICU discharges (increased throughput, decreased ICU step-down days and ICU readmission LOS) and improved survival for ICU patients requiring readmission, but overall ICU and hospital LOS and mortality, and ICU readmission rates were unchanged.
