Validation of a modified South African triage scale in a high-resource setting: a retrospective cohort study

BACKGROUND

Triage systems are widely used in emergency departments, but are not always validated. The South African Triage Scale (SATS) has mainly been studied in resource-limited settings. The aim of this study was to determine the validity of a modified version of the SATS for the general population of patients admitted to an ED at a tertiary hospital in a high-income country. The secondary objective was to study the triage performance according to age and patient categories.

METHODS

We conducted a retrospective cohort study of patients presenting to the Emergency Department of Haukeland University Hospital in Norway during a four-year period. We used short-term mortality, ICU admission, and the need for immediate surgery and other interventions as the primary endpoints.

RESULTS

A total of 162,034 emergency department visits were included in the analysis. The negative predictive value of a low triage level to exclude severe illness was 99.1% (95% confidence interval: 99.0-99.2%). The level of overtriage, defined as the proportion of patients assigned to a high triage level who were not admitted to the hospital, was 4.1% (3.9-4.2%). Receiver operating characteristic (ROC) curves showed an area under the ROC for the detection of severe illness of 0.874 (95% confidence interval: 0.870-0.879) for all patients and 0.856 (0.837-0.875), 0.884 (0.878-0.890) and 0.869 (0.862-0.876) for children, adults and elderly individuals respectively.

CONCLUSION

We found that the modified SATS had a good sensitivity to identify short-term mortality, ICU admission, and the need for rapid surgery and other interventions. The sensitivity was higher in adults than in children and higher in medical patients than in surgical patients. The over- and undertriage rates were acceptable.

Development of outcomes for evaluating emergency care triage: a Delphi approach

BACKGROUND

Triage is used as standard of care for prioritization and identification of time-critical patients in the emergency department (ED) globally, but it is unclear what outcomes should be used to evaluate triage. Currently used outcomes do not include important time-critical diagnoses and conditions.

METHOD

We used 18 Swedish triage experts to collect and assess outcomes for the evaluation of 5-level triage systems. The experts suggested 68 outcomes which were then tested through a modified Delphi approach in three rounds. The outcomes aimed to identify correctly prioritized red patients (in need of a resuscitation team), and orange patients (other time critical conditions). Consensus was pre-defined as 70% dichotomized (positive/negative) concordance.

RESULTS

Diagnoses, interventions, mortality, level of care and lab results were included in the outcomes. Positive consensus was reached for 49 outcomes and negative consensus for 7 outcomes, with an 83% response rate. The five most approved outcomes were the interventions Percutaneous coronary intervention, Surgical airway and Massive transfusion together with the diagnoses Tension pneumothorax and Intracerebral hemorrhage that received specific interventions. The outcomes with the clearest disapproval included Admittance to a ward, Treatment with antihistamines and The ordering of a head computed tomography scan. The outcomes were considered valid only if occurring in or from the ED.

CONCLUSION

This study proposes a standard of 49 outcomes divided into two sets tied to red and orange priority respectively, to be used when evaluating 5-level priority triage systems; Lund Outcome Set for Evaluation of Triage (LOSET). The proposed outcomes include diagnoses, interventions and laboratory results. Before widespread implementation of LOSET, prospective testing is needed, preferably at multiple sites.

Beyond objective measurements: Danish nurses' identification of hospitalized pediatric patients at risk of clinical deterioration - A qualitative study

PURPOSE

While the use of Pediatric Track and Trigger Tools as a standard to discriminate high level of urgency in pediatric care has received considerable attention, less focus has been given to other important factors such as nurses' clinical observations and judgement. The purpose of this study was to explore nurses' observational practice and focus on which non-measurable signs and symptoms nurses find important when identifying inpatient pediatric patients at risk of clinical deterioration.

DESIGN AND METHODS

This was an inductive qualitative study based on an interpretive description methodology. Data were obtained through participant observation of experienced nurses working in a Danish pediatric unit and focus group interviews with pediatric nurses. Field notes were taken, and focus group interviews were audio taped and transcribed. A thematic text condensation method was used to analyse data.

RESULTS

Findings revealed the following four main themes of non-measurable signs and symptoms that nurses find important when identifying children at risk of clinical deterioration: Colour and skin tone; sounds; movement patterns; behavioural signs.

CONCLUSIONS

This study suggest that pediatric patients show signs and symptoms that go beyond the objective measurements integrated in Pediatric Track and Trigger Tools and they should not be ignored as they are highly valuable to nurses who are responsible for observing inpatient pediatric patients at risk of clinical deterioration.

IMPLICATIONS

More empirical research on nurses' observational practice is recommended, especially research to identify the signs and symptoms - both measurable and non-measurable - that are significant to nurses at the bedside.
