Potential benefits of incentive spirometry following a rib fracture: a propensity score analysis.

CLINICIAN'S CAPSULEWhat is known about the topic?Literature regarding the impact of incentive spirometry on patients with rib fractures is unclear; there are no recommendations for its use in the emergency department (ED).What did this study ask?The objective of this study was to assess the impact of incentive spirometry on delayed complications in patients with rib fractures in the ED.What did this study find?Unsupervised incentive spirometry use does not have a protective effect against delayed pulmonary complications after a rib fracture.Why does this study matter to clinicians?Clear guidelines for incentive spirometry use for patients with rib fractures and further research to assess its usefulness in other ED populations are needed.

OBJECTIFS: La spirométrie incitative est parfois prescrite en vue d'encourager le rétablissement de la fonction respiratoire. Toutefois, peut de littérature est disponible sur la spirométrie incitative et ses effets chez les patients avec fracture de côtes, et il n'existe pas de recommandation sur son utilisation au département des urgences (DU), tout particulièrement pour les fractures de côtes, qui sont reconnues pour accroître le risque de complications pulmonaires. Cette étude visait donc à évaluer l'utilisation de la spirométrie incitative et à mesurer son impact sur l'incidence de complications tardives chez les patients ayant été libéré de l'urgence après une confirmation de fracture de côtes. MÉTHODE: Il s'agit d'une sous-étude planifiée d'une étude observationnelle de cohorte prospective, qui a eu lieu dans 4 DU au Canada, entre novembre 2006 et mai 2012. Des patients âgés de 16 ans et plus, non hospitalisés, avec au moins une fracture de côte confirmée par radiographie ont été sélectionnés. La décision de prescrire la spirométrie incitative était laissée à la discrétion du médecin traitant. Les principaux résultats consistaient en l'apparition d'une pneumonie, d'atélectasie ou d'un hémothorax dans les 14 jours suivant le traumatisme. Des analyses d'appariement des coefficients de propension ont été réalisées. RÉSULTATS: Un total de 439 patients ont participé à l'étude, dont 182 (41,5%) ont été reçu la spirométrie incitative. 99 cas d'hémothorax (22,6%), 103 cas d'atélectasie (23,5%) et 4 cas de pneumonie (0,9%) ont été observés. Nos résultats indiquent que la spirométrie incitative ne semble pas un moyen de protection contre l'hémothorax (risque relatif [RR] = 1,03 [0,66­1,64]) ni contre l'atélectasie ou la pneumonie (RR = 1,07 [0,68­1,72]). CONCLUSION: Nos résultats suggèrent que la spirométrie incitative non supervisée n'offrirait pas d'effet protecteur contre l'apparition tardive de complications pulmonaires à la suite d'une fracture de côtes. D'autres recherches sont nécessaires afin de valider la pertinence de prescrire la spirométrie incitative au DU, chez certains groupes de blessés plus spécifiques.

"One-way-street" streamlined admission of critically ill trauma patients reduces emergency department length of stay.

Emergency department (ED) overcrowding remains a significant problem in many hospitals, and results in multiple negative effects on patient care outcomes and operational metrics. We sought to test whether implementing a quality improvement project could decrease ED LOS for trauma patients requiring an ICU admission from the ED, specifically by directly admitting critically ill trauma patients from the ED CT scanner to an ICU bed. This was a retrospective study comparing patients during the intervention period (2013-2014) to historical controls (2011-2013). Critically ill trauma patients requiring a CT scan, but not the operating room (OR) or Interventional Radiology (IR), were directly admitted from the CT scanner to the ICU, termed the "One-way street (OWS)". Controls from the 2011-2013 Trauma Registry were matched 1:1 based on the following criteria: Injury Severity Score; mechanism of injury; and age. Only patients who required emergent trauma consult were included. Our primary outcome was ED LOS, defined in minutes. Our secondary outcomes were ICU LOS, hospital LOS and mortality. Paired t test or Wilcoxon signed rank test were used for continuous univariate analysis and Chi square for categorical variables. Logistic regression and linear regressions were used for categorical and continuous multivariable analysis, respectively. 110 patients were enrolled in this study, with 55 in the OWS group and 55 matched controls. Matched controls had lower APACHE II score (12 vs. 15, p = 0.03) and a higher GCS (14 vs. 6, p = 0.04). ED LOS was 229 min shorter in the OWS group (82 vs. 311 min, p < 0.0001). The time between CT performed and ICU disposition decreased by 230 min in the OWS arm (30 vs. 300 min, p < 0.001). There was no difference in ED arrival to CT time between groups. Following multivariable analysis, mortality was primarily predicted by the APACHE II score (OR 1.29, p < 0.001), and not ISS, mechanism of injury, or age. After controlling for APACHE II score, there was no difference in mortality between the two cohorts (OR = 0.49, p = 0.28). Expedited admission of critically ill trauma patients immediately following CT imaging significantly reduced ED LOS by 3.82 h (229 min), without a change in ICU LOS, hospital LOS, or mortality. Further studies are needed to assess the impact of expedited admission on morbidity and mortality.

Hypertonic saline in severe traumatic brain injury: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: Hypertonic saline solutions are increasingly used to treat increased intracranial pressure following severe traumatic brain injury. However, whether hypertonic saline provides superior management of intracranial pressure and improves outcome is unclear. We thus conducted a systematic review to evaluate the effect of hypertonic saline in patients with severe traumatic brain injury. METHODS: Two researchers independently selected randomized controlled trials studying hypertonic saline in severe traumatic brain injury and collected data using a standardized abstraction form. No language restriction was applied. We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, and BIOSIS databases. We searched grey literature via OpenGrey and National Technical Information Service databases. We searched the references of included studies and relevant reviews for additional studies. RESULTS: Eleven studies (1,820 patients) were included. Hypertonic saline did not decrease mortality (risk ratio 0.96, 95% confidence interval [CI] 0.83 to 1.11, I2=0%) or improve intracranial pressure control (weighted mean difference -1.25 mm Hg, 95% CI -4.18 to 1.68, I2=78%) as compared to any other solutions. Only one study reported monitoring for adverse events with hypertonic saline, finding no significant differences between comparison groups. CONCLUSIONS: We observed no mortality benefit or effect on the control of intracranial pressure with the use of hypertonic saline when compared to other solutions. Based on the current level of evidence pertaining to mortality or control of intracranial pressure, hypertonic saline could thus not be recommended as a first-line agent for managing patients with severe traumatic brain injury.

Acute minor thoracic injuries: evaluation of practice and follow-up in the emergency department.

OBJECTIVE: To review the management and follow-up of patients with minor thoracic injuries (MTI) treated by emergency or primary care physicians. DESIGN: A multicentre, retrospective study. SETTING: Three university-affiliated emergency departments of the metropolitan region of Quebec city, Que. PARTICIPANTS: Patients older than 16 years of age with suspected or proven rib fractures following traumatic events. MAIN OUTCOME MEASURES: Differences in admission and discharge proportions and disposition management following MTI. RESULTS: Four hundred and forty-seven charts were analyzed. Only 23 patients (5.2%) were admitted during the study period. Admission and discharge proportions were significantly different among the 3 surveyed hospitals, ranging from 1.3% to 15.2% (P < or = .001). There were no recommendations of follow-up noted in most (53.5%) of the charts and there were no differences after hospital stratification. Planned follow-up visits were scheduled for 5.7% of discharged patients. Being older than 65 years of age or having multiple rib fractures had no influence on management and follow-up recommendations. Eighty-two patients (18.6%) had unplanned follow-up visits in the emergency department, with inadequate pain relief as the principal reason for consultation (56.1%). There was no significant difference after stratification for age and type of analgesia. Other clinically significant delayed complications were recorded in 8.3% of all MTI patients. CONCLUSION: The proportion of patients admitted for rib fractures was lower than the expected 25%, based on previous publications, and varied across surveyed hospitals. A very low proportion of patients was offered planned follow-up visits or even any follow-up recommendations in view of possible delayed complications and disabilities. Further studies are needed to identify predictors of delayed MTI complications and enhance appropriate use of follow-up resources.
