Introduction of a mobile device based tertiary survey application reduces missed injuries: A multi-center prospective study.

BACKGROUND: Missed injuries during the initial assessment are a major cause of morbidity after trauma. The tertiary survey is a head-to-toe exam designed to identify any injuries missed after initial resuscitation. We designed a novel mobile device application (Physician Assist Trauma Software [PATS]) to standardize performance and documentation of the tertiary survey. This study was undertaken to assess the feasibility of introducing PATS into routine clinical practice, as well as its capacity to reduce missed injuries. METHODS: Prior to implementation of PATS, the missed injury rates at a higher-volume and a medium-volume level I trauma center were assessed. The PATS program was implemented simultaneously at both centers. Missed injuries were tracked during the study period. Compliance and tertiary survey completion rates were evaluated as a marker of feasibility. RESULTS: At the higher-volume trauma center, the missed injury rated decreased from 1% to 0% with the introduction of the PATS program (p = 0.04). At the medium-volume trauma center, the missed injury rate decreased from 9% to 1% (p < 0.001). Compliance and documentation increased from 68% to 100%, and from no formal documentation to 60% compliance at the higher- and medium-volume centers respectively. CONCLUSIONS: The implementation of a mobile tertiary survey application significantly reduced missed injuries at both a higher- and medium-volume trauma center. The use of this application resulted in a significant improvement in compliance with documentation of the tertiary survey.

Are retrievable vena cava filters placed in trauma patients really retrievable?

PURPOSE: Concerns have arisen regarding the use of retrievable inferior vena cava filters (rIVCFs) in trauma patients due to increasing reports of low retrieval rates. We hypothesized that complete follow-up with a dedicated trauma nurse practitioner would be associated with a higher rate of retrievability. This study was undertaken to determine the rate of retrievability of rIVCFs placed in a Canadian Lead Trauma Centre, and to compare the rate of retrievability in our trauma population to our non-trauma patients. METHODS: We performed a retrospective cohort study of all patients with rIVCF placed between Jan 1 2000 and June 30 2014. Data were collected on demographics, indication for filter placement, retrieval status, and reasons for non-retrieval. Comparison was made between trauma patients and non-trauma patients. RESULTS: A total of 374 rIVCFs were placed (61 in trauma patients and 313 in non-trauma patients) and follow-up was complete for the entire cohort. Filter retrieval was achieved in 86.9 % of trauma patients. Reasons for non-retrieval were technical in two patients, and death before retrieval in six patients. Retrieval was successful in 48.9 % of non-trauma patients. CONCLUSIONS: This study demonstrates that rIVCFs can be successfully retrieved amongst trauma patients. We demonstrated a higher rate of successful retrieval amongst trauma patients than non-trauma patients in our institution. Careful patient follow-up may play a role in successful retrieval of rIVCFs.

The use of trauma transfusion pathways for blood component transfusion in the civilian population: a systematic review and meta-analysis.

This study was undertaken to determine if, amongst civilian trauma patients requiring massive transfusion (MT), the use of a formal trauma transfusion pathway (TTP), in comparison with transfusion without a TTP, is associated with a reduction in mortality, or changes in indices of coagulation, blood product utilisation and complications. A systematic review of three bibliographic databases, reference lists and conference proceedings was conducted. Studies were included if comparisons were made between patients receiving transfusion with and without a TTP. Data were extracted by two independent reviewers on population characteristics, transfusion strategies, blood product utilisation, indices of coagulation, clinical outcomes and complications. Data were pooled using a random effects model and heterogeneity explored. Seven observational studies met all eligibility criteria. Amongst 1801 patients requiring MT, TTPs were associated with a significant reduction in mortality (RR 0·69, 95% CI 0·55, 0·87). No significant increase in the mean number of PRBC transfused between TTP and control patients was seen (MD -1·17 95% CI -2·70, 0·36). When studies assessing only trauma patients were considered, TTPs were associated with a reduction in the mean number of units of plasma transfused (MD -2·63, 95% CI -4·24, -1·01). In summary, the use of TTPs appears to be associated with a reduction in mortality amongst trauma patients requiring MT without a clinically significant increase in the number of PRBC transfused and a potential reduction in plasma transfusion. Effects of TTPs on platelet transfusion, indices of coagulation and complications remain unclear. A randomised controlled trial is warranted.
