Standardised early warning scores in rural interfacility transfers: A pilot study into their potential as a decision-making aid.

INTRODUCTION: While 12.4% of British Columbians live rurally, only 2.0% of specialists practise rurally, making interfacility transport of high-acuity patients vital. Decision-making aids have been identified as a way to improve the interfacility transfer process. We conducted a pilot study to explore the potential of the Standardised Early Warning Score (SEWS) as a decision-making aid for staff at sending facilities. METHODS: SEWSs were calculated from a database of 418 transfers from sending facilities in rural, small and medium population centres to larger receiving facilities. The SEWSs were compared against one another over time using McNemar's and the Wilcoxon signed-ranks tests. The SEWSs were then tested for their association with six outcomes using Pearson's or Fisher's Chi-squared test and the Mann-Whitney U-test. RESULTS: While at the sending facility, both the number of SEWSs that was four or greater and the average SEWS decreased over time (P < 0.001 for both). A first SEWS of four or greater was predictive of more intervention categories during transport (P = 0.047), an adverse event during transport (P = 0.004), an adverse event within 30 min of arrival at the receiving facility (P = 0.004) and death before discharge from the receiving facility (P = 0.043) but not deterioration during transport, or the length of stay at the receiving facility. CONCLUSION: Overall, the performance of the SEWS in the context of rural interfacility transport suggests that the tool will have utility in supporting decision-making.

Introduction: Alors que 12,4 % des résidents de la Colombie-Britannique vivent en milieu rural, seuls 2,0 % des spécialistes y pratiquent, ce qui rend essentiel le transport entre établissements des patients en état grave. Des outils de prise de décision ont été désignés comme méthode pour améliorer le processus de transfert entre établissements. Dans le cadre d'une étude pilote, nous nous sommes penchés sur le potentiel du score SEWS (Standardised Early Warning Score) comme outil de prise de décision à l'intention du personnel des établissements d'origine. Méthodes: Les scores SEWS ont été calculés dans une banque de données de 418 transferts d'établissements d'origine situés dans des agglomérations rurales de petite et moyenne taille vers des établissements de réception plus importants. Les scores SEWS ont été comparés entre eux dans le temps à l'aide des tests de McNemar et Wilcoxon Signed Ranks. L'association des scores SEWS à six paramètres d'évaluation a ensuite été testée à l'aide des tests de chi carré de Pearson ou de Fisher et du test de Mann-Whitney. Résultats: À l'établissement d'origine, le nombre de scores SEWS de quatre et plus et le score SEWS moyen se sont abaissés dans le temps (p < 0,001 dans les deux cas). Un score SEWS initial de quatre et plus prédisait un plus grand nombre de catégories d'interventions durant le transport (p = 0,047), la survenue d'un événement indésirable durant le transport (p = 0,004), la survenue d'un événement indésirable dans les 30 minutes après l'arrivée à l'établissement de réception (p = 0,004), et le décès avant le congé de l'établissement de réception (p = 0,043), mais il ne prédisait pas la détérioration durant le transport ni la durée du séjour à l'établissement de réception. Conclusion: Dans l'ensemble, le rendement du score SEWS dans le contexte du transport rural entre établissements laisse croire que l'outil serait utile à la prise de décision.

High acuity rural transport: findings from a qualitative investigation.

INTRODUCTION: The High Acuity Response Team (HART) was introduced in British Columbia (BC), Canada, to fill a gap in transport for rural patients that was previously being met by nurses and physicians leaving their communities to escort patients in need of critical care. The HART team consists of a critical care registered nurse (CCRN) and registered respiratory therapist (RRT) and attends acute care patients in rural sites by either stabilizing them in their community or transporting them. HART services are deployed in partnership with provincial ambulance services, which provide vehicles and coordination of all requests in the province for patient transport. This article presents the qualitative findings from a research evaluation of the efficacy of the HART model, including staffing and inter-organizational functioning. METHOD: Open-ended qualitative research interviewing was done with key stakeholders from 21 sites. Research participants included HART CCRNs, RRTs, administrative leads, as well as local emergency department (ED) physicians and nurses. Thematic analysis was done of the transcripts. RESULTS: A total of 107 interviews in 21 study sites were completed. Participants described characteristics of the model, perceptions of efficacy and areas for improvement. Rural sites reported a decrease in physician- and nurse-accompanied transports for high-acuity patients due to the HART team, but also noted challenges in delayed deployment, sometimes leading to adverse patient outcomes. CONCLUSIONS: The salient issues for the HART model were grounded in a somewhat artificial distinction between pre-hospital and interfacility transport for rural patients, which leads to a lack of service coordination and potentially avoidable delays. A beneficial systems change would be to move towards dedicated integration of high-acuity transport services into hospital organizational structures and community health services in rural areas.
