The objective of this study was to describe and compare the timing of cervical spine clearance in trauma patients with an unreliable physical examination. We prospectively included adult trauma patients admitted with a cervical collar and an unreliable clinical examination (as defined by the NEXUS criteria) at two level 1 trauma centers: one in the USA (US) and one in Denmark (DK). We excluded patients with cervical spine injuries requiring a collar or surgery as treatment and patients with a collar placed after hospital arrival. The primary outcome was time from emergency department (ED) arrival to collar removal. Secondary outcomes included time to CT of the cervical spine (CTCS). At the US trauma center, an institutional protocol allowing cervical spine clearance exclusively by CTCS was in place. At the Danish trauma center, cervical spine clearance was based on a clinical evaluation by an orthopedic surgeon, usually after CTCS. A total of 113 patients were included (US: n = 56; DK: n = 57). The median age was 47 years, and 68% were males. The main reasons for an unreliable physical examination were a Glasgow Coma Scale score below 14 (35%), distracting injuries (26%), cervical spine tenderness (13%) and intoxication (13%). The injury severity score at the US trauma center was higher than at the DK trauma center (median: 17 vs. 11, p = 0.03). Both time to CTCS (median: 41 vs. 18 min, p

Spontaneous retroperitoneal and rectus sheath hemorrhage (SRRSH) is associated with high mortality in the literature, but studies on the subject are lacking. The objective of this study was to identify early predictors of the need for angiographic or surgical intervention (ASI) in patients with SRRSH and define risk factors for mortality. We conducted a retrospective cohort study at a tertiary academic hospital. All patients with computed tomography-identified SRRSH between 2012 to 2017 were included. Exclusion criteria were age below 18 years, possible mechanical cause of SRRSH, aortic aneurysm rupture or dissection, and traumatic or iatrogenic sources of SRRSH. The primary outcome was the incidence of ASI and/or mortality. Of 100 patients included (median age 70 years, 52% males), 33% were transferred from another hospital, 82% patients were on therapeutic anticoagulation, and 90% had serious comorbidities. Overall mortality was 22%, but SRRSH-related mortality was only 6%. Sixteen patients underwent angiographic intervention (n = 10), surgical intervention (n = 5), or both (n = 1). Flank pain (OR 4.15, 95% CI 1.21–14.16, p = 0.023) and intravenous contrast extravasation (OR 3.89, 95% CI 1.23–12.27, p = 0.020) were independent predictors of ASI. Transfer from another hospital (OR 3.72, 95% CI 1.30–10.70, p = 0.015), age above 70 years (OR 4.24, 95% CI 1.25–14.32, p = 0.020), and systolic blood pressure below 110 mmHg at the time of diagnosis (OR 4.59, 95% CI 1.19–17.68, p = 0.027) were independent predictors of mortality. SRRSH is associated with high mortality but is typically not the direct cause. Most SRRSHs are self-limited and require no intervention. Pattern identification of ASI is hard.

The impact of immunosuppression on the outcomes of emergent surgery remains poorly described. We aimed to quantify the impact of chronic immunosuppression on outcomes of patients undergoing emergent colectomy (EC). The Colectomy-Targeted ACS-NSQIP database 2012–2016 was queried for patients who underwent colectomy for an emergent indication. As per NSQIP, chronic immunosuppression was defined as the use of corticosteroid or immunosuppressant medication within the prior 30 days. Patients undergoing EC for any indication were divided into two groups: immunosuppressant use (IMS) and no immunosuppressant use (NIS). Patients were propensity-score-matched on demographics, comorbidities, preoperative laboratory values, and operative variables in a 1:1 ratio to control for confounding factors. The primary outcome was 30-day mortality. Secondary outcomes included overall 30-day morbidity, individual postoperative complications (e.g., wound dehiscence, anastomotic leak, and sepsis), and hospital length of stay. Out of a total of 130,963 patients, 17,707 patients underwent an EC, of which 15,422 were NIS and 2285 were IMS. Totally, 2882 patients were matched (1441 NIS; 1441 IMS). The median age was 66 [IQR 56–76]; 56.8% were female; patients more frequently underwent a diversion procedure rather than primary anastomosis (68.4% vs 31.6%). Overall, as compared to NIS, IMS patients had higher 30-day mortality (21.4% vs 18.5%, p = 0.045) and overall morbidity (79.7% vs 75.7%, p = 0.011). Particularly, IMS patients had increased rates of unplanned intubations (11.5% vs 7.9%, p = 0.001), wound dehiscence (5.7% vs 3.5%, p = 0.006), progressive renal insufficiency 2.2% vs 1.2%, p = 0.042), pneumonia (12.6% vs 10.0%, p = 0.029), and longer median hospital length of stay [12.0 (8.0–21.0) vs 11.0 (7.0–19.0), p
