Repatriations and 28-day mortality of ill and injured travellers: 12 years of experience in a Swiss emergency department

QUESTIONS UNDER STUDY Many persons are travelling all over the world; the elderly with pre-existing diseases also travel to places with less developed health systems. Reportedly, fewer than 0.5% of all travellers need repatriation. We aimed to analyse and examine people who are injured or ill while abroad, where they travelled to and by what means they were repatriated. METHODS Retrospective cross-sectional study with adult patients repatriated to a single level 1 trauma centre in Switzerland (2000-2011). RESULTS A total of 372 patients were repatriated, with an increasing trend per year. Of these, 67% were male; the median age was 56 years. Forty-nine percent sustained an injury, and 13% had surgical and 38% medical pathologies. Patients with medical conditions were older than those with injuries or surgical emergencies (p <0.001). Seventy-three percent were repatriated from Europe. For repatriation from Africa trauma was slightly more frequent (53%, n = 17) than illnesses, whereas for most other countries illnesses and trauma were equally distributed. Injured patients had a median Injury Severity Score of 8. The majority of illnesses involved the nervous system (38%), mainly stroke. Forty-five percent were repatriated by Swiss Air Ambulance, 26% by ground ambulance, 18% by scheduled flights with or without medical assistance and two patients injured near the Swiss boarder by helicopter. The 28-day mortality was 4%. CONCLUSIONS The numbers of travellers repatriated increased from 2000 to 2011. About half were due to illnesses and half due to injuries. The largest group were elderly Swiss nationals repatriated from European countries. As mortality is relatively high, special consideration to this group of patients is warranted.

Comparison of Bispectral Index (BIS) and Patient State Index (PSI) as objective measures of sedation and analgesia in critically ill/injured patients

Critically ill and injured patients require pain relief and sedation to reduce the body's stress response and to facilitate painful diagnostic and therapeutic procedures. Presently, the level of sedation and analgesia is guided by the use of clinical scores which can be unreliable. There is therefore, a need for an objective measure of sedation and analgesia. The Bispectral Index (BIS) and Patient State Index (PSI) were recently introduced into clinical practice as objective measures of the depth of analgesia and sedation. ^ Aim. To compare the different measures of sedation and analgesia (BIS and PSI) to the standard and commonly used modified Ramsay Score (MRS) and determine if the monitors can be used interchangeably. ^ Methods. MRS, BIS and PSI values were obtained in 50 postoperative cardiac surgery patients requiring analgesia and sedation from June to December 2004. The MRS, BIS and PSI values were assessed hourly for up to 6-h by a single observer. ^ The relationship between BIS and PSI values were explored using scatter plots and correlation between MRS, BIS and PSI was determined using Spearman's correlation coefficient. Intra-class correlation (ICC) was used to determine the inter-rater reliability of MRS, BIS and PSI. Kappa statistics was used to further evaluate the agreement between BIS and PSI at light, moderate and deep levels of sedation. ^ Results. There was a positive correlation between BIS and PSI values (Rho = 0.731, p<0.001). Intra-class correlation between BIS and PSI was 0.58, MRS and BIS 0.43 and MRS and PSI 0.27. Using Kappa statistics, agreement between MRS and BIS was 0.35 (95% CI: 0.27–0.43) and for MRS and PSI was 0.21 (95% CI: 0.15–0.28). The kappa statistic for BIS and PSI was 0.45 (95% CI: 0.37–0.52). Receiver operating characteristics (ROC) curves constructed to detect undersedation indicated an area under the curve (AUC) of 0.91 (95% CI = 0.87 to 0.94) for the BIS and 0.84 (95% CI = 0.79 to 0.88) for the PSI. For detection of oversedation, AUC for the BIS was 0.89 (95% CI = 0.84 to 0.92) and 0.80 (95% CI = 0.75 to 0.85) for the PSI. ^ Conclusions. There is a statistically significant positive correlation between the BIS and PSI but poor correlation and poor test agreement between the MRS and BIS as well as MRS and PSI. Both the BIS and PSI demonstrated a high level of prediction for undersedation and oversedation; however, the BIS and PSI can not be considered interchangeable monitors of sedation. ^

Risk factors of pneumonia in traumatic spinal-cord-injured patients

Pneumonia is a well-documented and common respiratory infection in patients with acute traumatic spinal cord injuries, and may recur during the course of acute care. Using data from the North American Clinical Trials Network (NACTN) for Spinal Cord Injury, the incidence, timing, and recurrence of pneumonia were analyzed. The two main objectives were (1) to investigate the time and potential risk factors for the first occurrence of pneumonia using the Cox Proportional Hazards model, and (2) to investigate pneumonia recurrence and its risk factors using a Counting Process model that is a generalization of the Cox Proportional Hazards model. The results from survival analysis suggested that surgery, intubation, American Spinal Injury Association (ASIA) grade, direct admission to a NACTN site and age (older than 65 or not) were significant risks for first event of pneumonia and multiple events of pneumonia. The significance of this research is that it has the potential to identify patients at the time of admission who are at high risk for the incidence and recurrence of pneumonia. Knowledge and the time of occurrence of pneumonias are important factors for the development of prevention strategies and may also provide some insights into the selection of emerging therapies that compromise the immune system. ^
