More harmful errors are reported in ICU than non-ICU settings. Medication errors occur frequently in the administration phase in the ICU. When errors occur, patients and their caregivers are rarely informed. Consideration should be given to developing additional safeguards against ICU errors, particularly during drug administration, and eliminating barriers to error disclosures.

Background: In 2016, the World Health Organization (WHO) strongly recommended the use of a high fraction of inspired oxygen (FiO 2 ) in adult patients undergoing general anaesthesia to reduce the risk of surgical site infection (SSI). Since then, further trials have been published, trials included previously have come under scrutiny, and one article was retracted. We updated the systematic review on which the recommendation was based. Methods: We performed a systematic literature search from January 1990 to April 2018 for RCTs comparing the effect of high (80%) vs standard (30e35%) FiO 2 on the incidence of SSI. Studies retracted or under investigation were excluded. A random effects model was used for meta-analyses; the sources of heterogeneity were explored using meta-regression. Results: Of 21 RCTs included, six were newly identified since the publication of the WHO guideline review; 17 could be included in the final analyses. Overall, no evidence for a reduction of SSI after the use of high FiO 2 was found [relative risk (RR): 0.89; 95% confidence interval (CI): 0.73e1.07]. There was evidence that high FiO 2 was beneficial in intubated patients [RR: 0.80 (95% CI: 0.64e0.99)], but not in non-intubated patients [RR: 1.20 (95% CI: 0.91e1.58); test of interaction; P¼0.048]. Conclusions: The WHO updated analyses did not show definite beneficial effect of the use of high perioperative FiO 2 , overall, but there was evidence of effect of reducing the SSI risk in surgical patients under general anaesthesia with tracheal intubation. However, the evidence for this beneficial effect has become weaker and the strength of the recommendation needs to be reconsidered.

IMPORTANCE Eye trauma is a common cause of vision loss and a substantial public health problem.OBJECTIVE To determine the changes in the incidence of eye trauma hospitalizations in the United States and compare the demographics of affected patients and outcomes of eye trauma as a primary or secondary admitting diagnosis. DESIGN, SETTING, AND PARTICIPANTSThis retrospective longitudinal cohort study used the National Inpatient Sample, a representative sample of all US community hospitals, to determine the incidence, characteristics, and causes of primary and secondary inpatient eye trauma admissions from 2001 through 2014. All inpatients with relevant diagnoses were included. Linear regression was used to estimate changes in incidence. Logistic regression was used to compare demographics and outcomes between primary and secondary diagnoses, including age, sex, race, income, primary payer, region, year of admission, length of stay, cost, and disposition at discharge. EXPOSURES Eye trauma.MAIN OUTCOMES AND MEASURES Incidence and characteristics of inpatient primary and secondary eye trauma. RESULTSFrom 2001 to 2014, there were an estimated 939 608 inpatient admissions (of whom 556 886 were male patients [59.3%]; overall mean [SD] age, 49.4 [25.2] years) in the United States because of eye trauma diagnoses, with 778 967 of these (82.9%) as a secondary diagnosis. The incidence of primary eye trauma decreased from 3.9 to 3.0 per 100 000 population (difference, 0.9 [95% CI, 0.2-1.6] per 100 000 population; P = .001). The incidence of eye trauma as a secondary admitting diagnosis increased from 14.5 to 19.0 per 100 000 population (difference, 4.5 [95% CI, 1.9-7.2] per 100 000 population; P = .004). This was largely attributed to an increasing number of falls in individuals older than 65 years. The most frequent diagnosis was orbital fracture (64 149 [39.9%]) for primary trauma and contusion of eye and adnexa (19 301 [37.8%]) for secondary trauma. Primary trauma was more common in children (adjusted odds ratio [aOR], 2.21 [95% CI, 2.09-2.32]) and adolescents (aOR, 1.25 [95% CI,) than adults (reference), African American individuals (aOR, 1.89 [95% CI, 1.81-1.97]) and Hispanic individuals (aOR, 1.52 [95% CI, 1.45-1.59]) than white individuals, and uninsured patients (aOR, 1.14 [95% CI, 1.07-1.22]) and those receiving Medicaid (aOR, 1.12 [95% CI, 1.05-1.19]) than Medicare beneficiaries. Patients with a primary diagnosis were more likely to have a stay of less than 3 days (patients with a primary diagnosis: 101 796 [63.4%]; secondary diagnosis: 274 538 [35.2%]), more likely to have costs in the lowest quartile (patients with a primary diagnosis: 51 212 [31.9%]; secondary diagnosis: 166 260 [21.3%]), and less likely to die (patients with a primary diagnosis: 526 [0.3%]; secondary diagnosis: 20 929 [2.7%]).CONCLUSIONS AND RELEVANCE These findings suggest that the increasing number of falls in individuals older than 65 years and the high risk of primary eye trauma in populations such as children and adolescents warrant the devel...

Background: Evidence-based guidelines from the World Health Organization (WHO) have recommended a high (80%) fraction of inspired oxygen (FiO 2 ) to reduce surgical site infection in adult surgical patients undergoing general anaesthesia with tracheal intubation. However, there is ongoing debate over the safety of high FiO 2 . We performed a systematic review to define the relative risk of clinically relevant adverse events (AE) associated with high FiO 2 . Methods: We reviewed potentially relevant articles from the WHO review supporting the recommendation, including an updated (July 2018) search of EMBASE and PubMed for randomised and non-randomised controlled studies reporting AE in surgical patients receiving 80% FiO 2 compared with 30e35% FiO 2 . We assessed study quality and performed meta-analyses of risk ratios (RR) comparing 80% FiO 2 against 30e35% for major complications, mortality, and intensive care admission. Results: We included 17 moderateegood quality trials and two non-randomised studies with serious-critical risk of bias. No evidence of harm with high FiO 2 was found for major AE in the meta-analysis of randomised trials: atelectasis RR 0.91 [95% confidence interval (CI) 0.59e1.42); cardiovascular events RR 0.90 (95% CI 0.32e2.54); intensive care admission RR 0.93 (95% CI 0.7e1.12); and death during the trial RR 0.49 (95% CI 0.17e1.37). One non-randomised study reported that high FiO 2 was associated with major respiratory AE [RR 1.99 (95% CI 1.72e2.31)]. Conclusions: No definite signal of harm with 80% FiO 2 in adult surgical patients undergoing general anaesthesia was demonstrated and there is little evidence on safety-related issues to discourage its use in this population.

Even a modest reduction in the proportion of emergent procedures for 3 conditions is estimated to save nearly $1 billion over 10 years. Preventing emergency surgery through improved care coordination and screening offers a tremendous opportunity to save lives and decrease costs.

When clinical and laboratory parameters are included, a model predicting intraoperative MT in patients undergoing liver transplantation is sufficiently accurate that its predictions could guide the blood order schedule for individual patients based on institutional data, thereby reducing the impact on blood bank resources. Ongoing evaluation of model accuracy and transfusion practices is required to ensure continuing performance of the predictive model.

Background Clinical monitoring of cerebral blood flow (CBF) autoregulation in patients undergoing liver transplantation may provide a means for optimizing blood pressure to reduce the risk of brain injury. The purpose of this pilot project is to test the feasibility of autoregulation monitoring with transcranial Doppler (TCD) and near infrared spectroscopy (NIRS) in patients undergoing liver transplantation and to assess changes that may occur perioperatively. Methods We performed a prospective observational study in 9 consecutive patients undergoing orthotopic liver transplantation. Patients were monitored with TCD and NIRS. A continuous Pearson’s correlation coefficient was calculated between mean arterial pressure (MAP) and CBF velocity and between MAP and NIRS data, rendering the variables mean velocity index (Mx) and cerebral oximetry index (COx), respectively. Both Mx and COx were averaged and compared during the dissection phase, anhepatic phase, first 30 mins of reperfusion, and remaining reperfusion phase. Impaired autoregulation was defined as Mx ≥ 0.4. Results Autoregulation was impaired in one patient during all phases of surgery, in two patients during the anhepatic phase, and in one patient during reperfusion. Impaired autoregulation was associated with a MELD score > 15 (p=0.015) and postoperative seizures or stroke (p<0.0001). Analysis of Mx categorized in 5-mmHg bins revealed that MAP at the lower limit of autoregulation (MAP when Mx increased to ≥ 0.4) ranged between 40 and 85 mmHg. Average Mx and average COx were significantly correlated (p=0.0029). The relationship between COx and Mx remained when only patients with bilirubin > 1.2 mg/dL were evaluated (p=0.0419). There was no correlation between COx and baseline bilirubin (p=0.2562) but MELD score and COx were correlated (p=0.0458). Average COx was higher for patients with a MELD score > 15 (p=0.073) and for patients with a neurologic complication than for patients without neurologic complications (p=0.0245). Conclusions These results suggest that autoregulation is impaired in patients undergoing liver transplantation, even in the absence of acute, fulminant liver failure. Identification of patients at risk for neurologic complications after surgery may allow for prompt neuroprotective interventions, including directed pressure management.

Socio-demographic and injury factors, such as age, race, hypotension on admission, and severity and mechanism of injury predict post-traumatic sepsis significantly. Further exploration to explain why these patient groups are at increased risk is warranted in order to understand better and potentially prevent this life-threatening complication.
