Adherence to national trauma triage criteria in Norway: a cross-sectional study.

Abstract

Background: Norwegian hospitals employed individual trauma triage criteria until 2015 when nationwide criteria were implemented. There is a lack of empirical evidence regarding adherence to Norwegian national criteria for activation of the trauma team (NTrC) and the decision-making processes regarding trauma team activation (TTA) within Norwegian trauma hospitals. The objectives of this study were to investigate institutional adherence to the NTrC and to investigate similarities and differences in the decision-making process leading to TTA in Norwegian trauma hospitals.

Methods: A digital semi-structured questionnaire regarding adherence to criteria, TTA decision-making and criteria documentation was distributed to all Norwegian trauma hospitals (n = 38) in the spring of 2022. Contact details of trauma coordinators and registrars were provided by the Norwegian Trauma Registry secretariat. Follow-up telephone interviews were conducted at the investigator's discretion in cases of non-respondents or need to clarify answers.

Results: Thirty-eight trauma hospitals were invited to answer the survey, where 35 hospitals responded (92%), making 35 the denominator of the results. Thirty-four (97.1%) hospitals stated that they followed NTrC. Thirty-three (94.3%) of the responding hospitals provided documentation of their criteria in use, of which twenty-eight (80%) of responding hospitals adhered to the NTrC. Three (8.6%) hospitals employed a tiered TTA approach with different sized teams. In addition four hospitals (11.4%) used specialized teams to meet the needs of defined patient groups (e.g. geriatric patients, traumatic brain injury). Twenty-one (60%) of the responding hospitals had written guidelines on who could perform TTA and in 18 hospitals (51.4%) TTA could be performed by pre-hospital personnel. Twenty-three (65.7%) of the hospitals documented which criteria that were used for TTA.

Conclusion: There is good adherence to the national criteria for activation of the trauma team among Norwegian trauma hospitals after implementation of national guidelines. Individual hospitals argue the use of certain local criteria and trauma team activation decision-making processes to increase their precision in specific patient populations and demographics. Further steps should be done to reduce the variation in TTA decision-making processes among hospitals and improve documentation quality.
