More than 90 per cent of cholecystectomies are performed laparoscopically and this has resulted in concern that surgeons will not have sufficient experience to perform open procedures when clinical circumstances require it. We reviewed the open cholecystectomies (OCs) of Medicare patients from 2010 to 2012 in hospitals with 20 or more cases, created risk-adjusted models for adverse outcomes which were evaluated for 90-days after discharge, and compared the hospital-level outcomes with laparoscopic cholecystectomy performed in the same hospitals for the same period of time. Results demonstrated that inpatient deaths, inpatient prolonged length-of-stay outliers, 90-day postdischarge deaths without readmission, and 90-day readmissions were statistically the same with an overall adverse outcome rate of 21.6 per cent in OC versus 20.9 per cent in laparoscopic cholecystectomy. Conversion of laparoscopic to open procedures was not associated with increased adverse outcomes. Laparoscopic cholecystectomy provides patients with many advantages, but when clinical circumstances are necessary, OC continues to be performed with the same overall adverse outcome rates, and the conversion process is not associated with poorer results in this high-risk population of patients.

Objectives. Extended time in the emergency department (ED) has been related to adverse outcomes among stroke patients. We examined the associations of ED nursing shift change (SC) and length of stay in the ED with outcomes in patients with intracerebral hemorrhage (ICH). Methods. Data were collected on all spontaneous ICH patients admitted to our stroke center from 7/1/08–6/30/12. Outcomes (frequency of pneumonia, modified Rankin Scale (mRS) score at discharge, NIHSS score at discharge, and mortality rate) were compared based on shift change experience and length of stay (LOS) dichotomized at 5 hours after arrival. Results. Of the 162 patients included, 60 (37.0%) were present in the ED during a SC. The frequency of pneumonia was similar in the two groups. Exposure to an ED SC was not a significant independent predictor of any outcome. LOS in the ED ≥5 hours was a significant independent predictor of discharge mRS 4–6 (OR 3.638, 95% CI 1.531–8.645, and P = 0.0034) and discharge NIHSS (OR 3.049, 95% CI 1.491–6.236, and P = 0.0023) but not death. Conclusions. Our study found no association between nursing SC and adverse outcome in patients with ICH but confirms the prior finding of worsened outcome after prolonged length of stay in the ED.

Abstract Background/Introduction According to the European Society of Cardiology (ESC) 2014 guideline, systemic hypotension (HT) is the critical variable defining high-risk in patients with pulmonary embolism (PE). However, signs of organ hypoperfusion might more adequately identify PE patients with cardiogenic shock due to right ventricular (RV) failure. Purpose We investigated whether hypoperfusion markers provide superior prognostic information for identifying PE patients at highest risk of early adverse outcomes. Methods Consecutive PE patients enrolled in a prospective single-centre registry between 09/2008 and 03/2018 were included. We analysed the predictive value of symptoms and findings suggesting hypoperfusion for in-hospital adverse outcome (catecholamine treatment, resuscitation or PE-related death) and in-hospital all-cause mortality. Results We analysed 814 patients, including 83 (10.2%) ESC 2014 high-risk patients. Patients presenting with cardiac arrest (CA, 4.5%) were a priori defined as high risk. Markers suggesting hypoperfusion of the brain (altered metal status, odds ratio [OR] 8.2 [95% CI, 4.2–16.0]), lung (respiratory insufficiency, 25.0 [9.4–66.7]) and tissue (venous lactate ≥2.2 mmol/l, 6.4 [3.2–12.9]) as well as HT (13.5 [6.7–27.2]) predicted an adverse outcome. The risk for an adverse outcome increased with the number of positive markers (AUC 0.86 [0.80–0.93]). Patients with ≥3 positive hypoperfusion markers had an OR of 42.9 (11.0–167.3) and patients defined as high-risk by the ESC 2014 an OR of 17.2 (8.8–33.3) with regard to an adverse outcome (Figure 1; Table 1). A new definition of high-risk (CA or ≥3 hypoperfusion markers) was associated with an OR of 73.2 (31.3–171.1) for an in-hospital adverse outcome and 26.2 (12.1–56.7) for in-hospital mortality. Table 1.

Risk increases with the number of positive markers and is critically elevated in patients presenting with CA or ≥3 markers.

Background: Little is known about clinical outcomes of patients with acute myocardial infraction (AMI) complicated by cardiogenic shock (CS) requiring mechanical ventilation (MV). The aim of this study was to identify the characteristics, risk factors, and outcomes associated with the provision of MV in this specific high-risk population. Methods: Patients with CS complicating AMI and multivessel coronary artery disease from the CULPRIT-SHOCK trial were included. We explored 30 days of clinical outcomes in patients not requiring MV, those with MV on admission, and those in whom MV was initiated within the first day after admission. Results: Among 683 randomized patients included in the analysis, 17.4% received no MV, 59.7% were ventilated at admission and 22.8% received MV within or after the first day after admission. Patients requiring MV had a different risk-profile. Factors independently associated with the provision of MV on admission included higher body weight, resuscitation within 24 h before admission, elevated heart rate and evidence of triple vessel disease. Conclusions: Requiring MV in patients with CS complicating AMI is common and independently associated with mortality after adjusting for covariates. Patients with delayed MV initiation appear to be at higher risk of adverse outcomes. Further research is necessary to identify the optimal timing of MV in this high-risk population.

PurposeObstetric adverse outcomes (AOs) are an important topic and the use of composite measures may favor the understanding of their impact on patient safety. The aim of the present study was to estimate AO frequency and obstetric care quality in low and high-risk maternity hospitals.Design/methodology/approachA one-year longitudinal follow-up study in two public Brazilian maternity hospitals. The frequency of AOs was measured in 2,880 randomly selected subjects, 1,440 in each institution, consisting of women and their newborn babies. The frequency of 14 AOs was estimated every two weeks for one year, as well as three obstetric care quality indices based on their frequency and severity as follows: the Adverse Outcome Index (AOI), the Weighted Adverse Outcome Score and the Severity Index.FindingsA significant number of mothers and newborns exhibited AOs. The most prevalent maternal AOs were admission to the ICU and postpartum hysterectomy. Regarding newborns, hospitalization for > seven days and neonatal infection were the most common complications. Adverse outcomes were more frequent at the high-risk maternity, however, they were more severe at the low-risk facility. The AOI was stable at the high-risk center but declined after interventions during the follow-up year.Originality/valueHigh AO frequency was identified in both mothers and newborns. The results demonstrate the need for public patient safety policies for low-risk maternity hospitals, where AOs were less frequent but more severe.

Introduction: Delirium is a frequent pathology in the elderly presenting to the emergency department (ED) and is seldom recognised. This condition is associated with many medical complications and has been shown to increase the hospital length-of-stay. The objective of this study was to identify the predictor factors of developing delirium in this high-risk population. Methods: Design: This study was part of the multicenter prospective cohort INDEED study. Participants: Patients aged 65 and older, initially free of delirium and with an ED stay of 8h or longer, were followed up to 24h after ward admission. Measures: Clinical and demographic variables were collected by interview and chart review. A research professional assessed their delirium status twice daily using the Confusion Assessment Method (CAM). Analyses: A classification tree was used to select predictors and cut-points that minimized classification error of patients with incident delirium. After literature review, nineteen predictors were considered for inclusion in the model (eight non-modifiable and eleven modifiable factors). Results: Among the 605 patients included in this study, incident delirium was detected by the CAM in 69 patients (11.4%). In total, fourteen variables were included in a preliminary model, of which six were intrinsic to the patient and eight were modifiable in the ED. Variables with the greatest impact in the prediction of delirium includes age, cognitive status, ED length of stay, autonomy in daily activities, fragility and mobility during their hospital stay. The diagnostic performance of the model applied to the study sample gave a sensitivity of 78.3% (95% CI: 66.7 to 87.3), a specificity of 100.0% (95% CI: 99.3 to 100.0), a PPV of 100.0% (95% CI: 93.4 to 100.0) and a NPV of 97.3% (95% CI: 95.6 to 98.5). Conclusion: The delirium risk model developed in this study shows promising results with elevated sensitivity and specificity values. Considering the limited ability to predict and detect delirium among physicians, the potential increase in sensitivity provided by this tool could be beneficial to patients. This model will ultimately serve to identify high-risk patients with the goal of developing strategies to alter modifiable risk factors and subsequently decrease the incidence of delirium in this population.

Background—Malignant colorectal polyps are defined as endoscopically removed polyps with cancerous tissue which has invaded the submucosa. Various histological criteria exist for managing these patients.Aims—To determine the significance of histological findings of patients with malignant polyps.Methods—Five pathologists reviewed the specimens of 85 patients initially diagnosed with malignant polyps. High risk malignant polyps were defined as having one of the following: incomplete polypectomy, a margin not clearly cancer-free, lymphatic or venous invasion, or grade III carcinoma. Adverse outcome was defined as residual cancer in a resection specimen and local or metastatic recurrence in the follow up period (mean 67 months).Results—Malignant polyps were confirmed in 70 cases. In the 32 low risk malignant polyps, no adverse outcomes occurred; 16 (42%) of the 38 patients with high risk polyps had adverse outcomes (p<0.001). Independent adverse risk factors were incomplete polypectomy and a resected margin not clearly cancer-free; all other risk factors were only associated with adverse outcome when in combination.Conclusion—As no patients with low risk malignant polyps had adverse outcomes, polypectomy alone seems sufficient for these cases. In the high risk group, surgery is recommended when either of the two independent risk factors, incomplete polypectomy or a resection margin not clearly cancer-free, is present or if there is a combination of other risk factors. As lymphatic or venous invasion or grade III cancer did not have an adverse outcome when the sole risk factor, operations in such cases should be individually assessed on the basis of surgical risk.

To externally validate the prognostic impact of copeptin, either alone or integrated in risk stratification models, in pulmonary embolism (PE), we performed a post hoc analysis of 843 normotensive PE patients prospectively included in three European cohorts.Within the first 30 days, 21 patients (2.5%, 95% CI 1.5–3.8) had an adverse outcome and 12 (1.4%, 95% CI 0.7–2.5) died due to PE. Patients with copeptin ≥24 pmol·L−1 had a 6.3-fold increased risk for an adverse outcome (95% CI 2.6–15.5, p<0.001) and a 7.6-fold increased risk for PE-related death (95% CI 2.3–25.6, p=0.001). Risk classification according to the 2014 European Society of Cardiology (ESC) guideline algorithm identified 248 intermediate-high-risk patients (29.4%) with 5.6% (95% CI 3.1–9.3) at risk of adverse outcomes. A stepwise biomarker-based risk assessment strategy (based on high-sensitivity troponin T, N-terminal pro-brain natriuretic peptide and copeptin) identified 123 intermediate-high-risk patients (14.6%) with 8.9% (95% CI 4.5–15.4) at risk of adverse outcomes. The identification of patients at higher risk was even better when copeptin was measured on top of the 2014 ESC algorithm in intermediate-high-risk patients (adverse outcome OR 11.1, 95% CI 4.6–27.1, p<0.001; and PE-related death OR 13.5, 95% CI 4.2–43.6, p<0.001; highest risk group versus all other risk groups). This identified 85 patients (10.1%) with 12.9% (95% CI 6.6–22.0) at risk of adverse outcomes and 8.2% (95% CI 3.4–16.2) at risk of PE-related deaths.Copeptin improves risk stratification of normotensive PE patients, especially when identifying patients with an increased risk of an adverse outcome.

Objective: Compare the risk of recurrent adverse delivery outcome (ADO) or adverse neonatal outcome (ANO) between consecutive gestational diabetes (GDM) pregnancies. Design: Retrospective cohort Setting: Sydney, Australia Population or Sample: 424 pairs of consecutive singleton GDM pregnancies, 2003-2015 Main Outcome Measures:. ADO: instrumental delivery and emergency Caesarean. ANO: large for gestational age (LGA), small for gestational age (SGA), and composite ANO (LGA/SGA/stillbirth/neonatal death/shoulder dystocia). Methods: Using each pregnancy pair (“index” and “subsequent” pregnancy), we calculated ADO and ANO rates and determined risk factors for subsequent pregnancy outcomes (multivariate regression). Results: Subsequent pregnancies had higher rates of elective Caesarean (30.4% vs 17.0%, p<0.001) and lower rates of instrumental delivery (5% vs 13.9%, p<0.001), emergency Caesarean (7.1% vs 16.3%, p<0.001) and vaginal delivery (62.3% vs 66.3%, p=0.01). ANO rates in index and subsequent pregnancies did not differ. Index pregnancy adverse outcome was associated with a higher risk of repeat outcome: RR 3.09 (95%CI:1.30, 7.34) for instrumental delivery, RR 2.20 (95%CI:1.06, 4.61) for emergency Caesarean, RR 4.55 (95%CI:3.03, 6.82) for LGA, RR 5.01 (95%CI:2.73, 9.22) for SGA and RR 2.10 (95%CI:1.53, 2.87) for composite ANO). The greatest risk factor for subsequent LGA (RR 3.13 (95%CI:2.20, 4.47)), SGA (RR 4.71 (95%CI:2.66, 8.36)) or composite ANO (RR 2.01 (95%CI:1.46, 2.78)) was having the same outcome in the index pregnancy. Conclusions: Women with GDM and an adverse outcome are at very high risk of the same complication in their subsequent GDM pregnancy, representing a high-risk group that should be targeted for directed management over routine care.
