The NELA risk prediction model for emergency laparotomies discriminates well between low- and high-risk patients and is suitable for producing risk-adjusted provider mortality statistics.

Background: Studies across healthcare systems have demonstrated between-hospital variation in survival after an emergency laparotomy. We postulate that this variation can be explained by differences in perioperative process delivery, underpinning organisational structures, and associated hospital characteristics. Methods: We performed this nationwide, registry-based, prospective cohort study using data from the National Emergency Laparotomy Audit organisational and patient audit data sets. Outcome measures were all-cause 30-and 90-day postoperative mortality. We estimated adjusted odds ratios (ORs) for perioperative processes and organisational structures and characteristics by fitting multilevel logistic regression models. Results: The cohort comprised 39 903 patients undergoing surgery at 185 hospitals. Controlling for case mix and clustering, a substantial proportion of between-hospital mortality variation was explained by differences in processes, infrastructure, and hospital characteristics. Perioperative care pathways [OR: 0.86; 95% confidence interval (CI): 0.76e0.96; and OR: 0.89; 95% CI: 0.81e0.99] and emergency surgical units (OR: 0.89; 95% CI: 0.80e0.99; and OR: 0.89; 95% CI: 0.81e0.98) were associated with reduced 30-and 90-day mortality, respectively. In contrast, infrequent consultant-delivered Quality and Patient Safety intraoperative care was associated with increased 30-and 90-day mortality (OR: 1.61; 95% CI: 1.01e2.56; and OR: 1.61; 95% CI: 1.08e2.39, respectively). Postoperative geriatric medicine review was associated with substantially lower mortality in older (!70 yr) patients (OR: 0.35; 95% CI: 0.29e0.42; and OR: 0.64; 95% CI: 0.55e0.73, respectively). Conclusions: This multicentre study identified low-technology, readily implementable structures and processes that are associated with improved survival after an emergency laparotomy. Key components of pathways, perioperative medicine input, and specialist units require further investigation.

In patients who require an emergency laparotomy with adhesiolysis or resection for SBO, a delay to surgery of more than 72 h is associated with a higher 30-day postoperative mortality rate.

ObjectivesThis study used national audit data to describe current management and outcomes of patients undergoing surgery for complications of peptic ulcer disease (PUD), including perforation and bleeding. It was also planned to explore factors associated with fatal outcome after surgery for perforated ulcers. These analyses were designed to provide a thorough understanding of current practice and identify potentially modifiable factors associated with outcome as targets for future quality improvement.DesignNational cohort study using National Emergency Laparotomy Audit (NELA) data.SettingEnglish and Welsh hospitals within the National Health Service.ParticipantsAdult patients admitted as an emergency with perforated or bleeding PUD between December 2013 and November 2015.InterventionsLaparotomy for bleeding or perforated peptic ulcer.Primary and secondary outcome measuresThe primary outcome was 60-day in-hospital mortality. Secondary outcomes included length of postoperative stay, readmission and reoperation rate.Results2444 and 382 procedures were performed for perforated and bleeding ulcers, respectively. In-hospital 60-day mortality rates were 287/2444 (11.7%, 95% CI 10.5% to 13.1%) for perforations, and 68/382 (17.8%, 95% CI 14.1% to 22.0%) for bleeding. Median (IQR) 2-year institutional volume was 12 (7–17) and 2 (1–3) for perforation and bleeding, respectively. In the exploratory analysis, age, American Society of Anesthesiology score and preoperative systolic blood pressure were associated with mortality, with no association with time from admission to operation, surgeon grade or operative approach.ConclusionsPatients undergoing surgery for complicated PUD face a high 60-day mortality risk. Exploratory analyses suggested fatal outcome was primarily associated with patient rather than provider care factors. Therefore, it may be challenging to reduce mortality rates further. NELA data provide important benchmarking for patient consent and has highlighted low institutional volume and high mortality rates after surgery for bleeding peptic ulcers as a target for future research and improvement.

Background: Socioeconomic circumstances can influence access to healthcare, the standard of care provided, and a variety of outcomes. This study aimed to determine the association between crude and risk-adjusted 30-day mortality and socioeconomic group after emergency laparotomy, measure differences in meeting relevant perioperative standards of care, and investigate whether variation in hospital structure or process could explain any difference in mortality between socioeconomic groups. Methods: This was an observational study of 58 790 patients, with data prospectively collected for the National Emergency Laparotomy Audit in 178 National Health Service hospitals in England between December 1, 2013 and November 31, 2016, linked with national administrative databases. The socioeconomic group was determined according to the Index of Multiple Deprivation quintile of each patient's usual place of residence. Results: Overall, the crude 30-day mortality was 10.3%, with differences between the most-deprived (11.2%) and leastdeprived (9.8%) quintiles (P<0.001). The more-deprived patients were more likely to have multiple comorbidities, were more acutely unwell at the time of surgery, and required a more-urgent surgery. After risk adjustment, the patients in the most-deprived quintile were at significantly higher risk of death compared with all other quintiles (adjusted odds ratio [95% confidence interval]: Q1 [most deprived]: reference; Q2: 0.83 [0.76e0.92]; Q3: 0.84 [0.76e0.92]; Q4: 0.87 [0.79e0.96]; Q5 [least deprived]: 0.77 [0.70e0.86]). We found no evidence that differences in hospital-level structure or patient-level performance in standards of care explained this association. Conclusions: More-deprived patients have higher crude and risk-adjusted 30-day mortality after emergency laparotomy, but this is not explained by differences in the standards of care recorded within the National Emergency Laparotomy Audit.

ObjectivesTo evaluate whether distance and estimated travel time to hospital for patients undergoing emergency laparotomy is associated with postoperative mortality.DesignNational cohort study using data from the National Emergency Laparotomy Audit.Setting171 National Health Service hospitals in England and Wales.Participants22 772 adult patients undergoing emergency surgery on the gastrointestinal tract between 2013 and 2016.Main outcome measuresMortality from any cause and in any place at 30 and 90 days after surgery.ResultsMedian on-road distance between home and hospital was 8.4 km (IQR 4.7–16.7 km) with a median estimated travel time of 16 min. Median time from hospital admission to operating theatre was 12.7 hours. Older patients live on average further from hospital and patients from areas of increased socioeconomic deprivation live on average less far away.We included estimated travel time as a continuous variable in multilevel logistic regression models adjusting for important confounders and found no evidence for an association with 30-day mortality (OR per 10 min of travel time=1.02, 95% CI 0.97 to 1.06, p=0.512) or 90-day mortality (OR 1.02, 95 % CI 0.97 to 1.06, p=0.472).The results were similar when we limited our analysis to the subgroup of 5386 patients undergoing the most urgent surgery. 30-day mortality: OR=1.02 (95% CI 0.95 to 1.10, p=0.574) and 90-day mortality: OR=1.01 (95% CI 0.94 to 1.08, p=0.858).ConclusionsIn the UK NHS, estimated travel time between home and hospital was not a primary determinant of short-term mortality following emergency gastrointestinal surgery.
