Socio-economic disparity in risk of undergoing emergency laparotomy and postoperative mortality.

Aims: Socio-economic disparities in health and access to care are well documented, but socio-economic disparities in surgical care and outcomes have received less attention. The aim of the study was to determine if there are socio-economic disparities in the risk of undergoing emergency laparotomy and postoperative mortality in a universal health-care system with free and equal access to care. Methods: This was a nationwide case-control study including patients undergoing non-malignant emergency laparotomy involving resection, ostomy or open drainage between 2003 and 2014 and population references matched 1:1 on age and sex. Socio-economic disparities in one-year postoperative mortality were explored through a cohort study including all patients. Exposure measures were register-based household disposable income, educational level and employment status. Analyses were adjusted by age, sex, country of origin, marital status and co-morbidity. Results: A total of 11,962 cases and 11,962 population references were included. The highest odds ratios (OR) for undergoing surgery were found among those with the lowest income (OR=1.51; 95% confidence interval (CI) 1.39-1.63), those with elementary school education (OR=1.33; 95% CI 1.22-1.46) and those on early-retirement pension (OR=3.49; 95% CI 3.07-3.98). One-year postoperative mortality was highest among those with lowest income (hazard ratio (HR)=1.51; 95% CI 1.35-1.69), those with elementary school education (HR=1.39; 95% CI 1.22-1.59) and those on early-retirement pension (HR=2.12; 95% CI 1.73-2.61). Conclusions: Socio-economic disparities in health exist in relation to non-malignant emergency laparotomies and still exist after adjustment for confounders, including co-morbidity, indicating that mechanisms other than differences in disease burden are involved. There is a substantial need for exploration of mechanisms and preventive measures.

Delay of surgery after stent placement for resectable malignant colorectal obstruction is associated with higher risk of recurrence.

BACKGROUND: Self-expanding metal stents can be used as bridge to elective surgery for acute malignant colonic obstruction. However, the impact on long-term oncological outcome and the optimal timing of surgery are still unknown. METHOD: This was a retrospective multicenter study performed at four colorectal centers. Patients undergoing stent placement as bridge to surgery, between January 2010 and December 2013, were included in the study. Primary outcomes were survival and recurrence rates along with location of the metastases. Additionally, we recorded time from stent placement to elective surgery. Secondary outcomes were postoperative complication rates. Complications were classified according to the Clavien-Dindo classification score. A logistic regression model was used to describe impact of delayed stent removal on risk of recurrence. RESULTS: This study included 112 patients, with a median follow-up of 43 months. Survival rate was 70%. We found a recurrence rate of 37%, primarily local recurrences (17%). Procedure-related complications at the stent placement were seen in 18%, and complications after subsequent elective surgery were seen in 39%. A significantly higher risk of recurrence with increased time from stent placement to elective surgery (OR 5.1 [1.6-15.8], p = 0.005) was found. CONCLUSION: Delay of elective surgery after stent placement may have a negative influence on long-term oncologic outcomes.

Chronic Pain, Quality of Life, and Functional Impairment After Surgery Due to Small Bowel Obstruction.

BACKGROUND: Emergency laparotomy is a high-risk procedure regarding short-term outcomes; however, long-term outcomes are not well described. The aim of this study was to determine the frequency of chronic postoperative pain, pain-related functional impairment, and incisional hernias and to evaluate the gastrointestinal quality of life after emergency laparotomy due to small bowel obstruction. METHODS: This study was a questionnaire study, conducted at a major gastrointestinal-surgery department in a single tertiary university hospital in Denmark. Patients who had been through emergency laparotomy due to small bowel obstruction were included in the study. The extent of acute and chronic postoperative pain and the prevalence of incisional hernias were examined with specially designed questionnaires, while the pain quality was assed by the self-report version of the S-LANSS-questionnaire. Pain-related functional impairment and quality of life were measured using the AAS and the GIQLI questionnaire, respectively. RESULTS: A total of 90 patients returned the questionnaire (response rate 82 %). Nineteen patients (21 %) suffered from chronic postoperative pain. Seventeen patients (19 %) had pain-related functional impairment as a result of the surgery, and 17 patients (19 %) had an incisional hernia at follow-up. Patients with chronic postoperative pain had significantly lower gastrointestinal quality of life score compared with the remaining study population (109 (IQR 39) vs. 127 (IQR 19), P < 0.001). CONCLUSIONS: Chronic postoperative pain is a common long-term complication after emergency laparotomy, and it is related to decreased quality of life. These results should be confirmed in prospective studies.

A nationwide cohort study of short- and long-term outcomes following emergency laparotomy.

INTRODUCTION: Emergency laparotomy is a high-risk procedure associated with severe post-operative morbidity and high mortality. The aim was to conduct a nationwide cohort consisting of all patients undergoing emergency laparotomy during an 11-year period and to examine both short- and long-term outcomes. METHODS: Adult patients treated with emergency laparotomy due to gastrointestinal conditions from 2003 through 2013 were identified in the Danish National Patient Register. Demographic data and surgical outcomes were identified in nationwide registers. RESULTS: A total of 47,300 patients were included in the study. Hereof, 15,015 patients underwent minor laparotomy (open appendectomy or cholecystectomy) and the rest underwent major laparotomy (n = 32,285). In all, 8,193 patients (17.3%) were readmitted within 30 days from surgery, whereas 7,521 patients (15.9%) underwent gastrointestinal reoperation. A total of 10,944 patients (23.1%) experienced a post-operative complication. The post-operative mortality at 7, 30, 90 and 365 days was 8.5%, 13.3%, 16.9% and 21.9%, respectively. When excluding minor laparotomies (open appendectomy and cholecystectomy), the 7-, 30-, 90- and 365-day mortality was 12.1%, 18.7%, 23.6% and 30.5%, respectively. CONCLUSIONS: More than one in every five patients died within one year after undergoing emergency laparotomy, and mortality rates were even higher when excluding minor laparotomies as almost one in every three patients died within one year. FUNDING: This study received support from the Frimodt-Heinecke Foundation and from the foundation Manufacturer Frands Køhler Nielsens and wife memorial fund. TRIAL REGISTRATION: The study was registered with Researchregistry.com (Id no: researchregistry2930).

Risk factors affecting morbidity and mortality following emergency laparotomy for small bowel obstruction: A retrospective cohort study.

INTRODUCTIONS: To identify risk factors for increased 30-day morbidity and mortality, using standardized measuring tools for the characterization of complications after emergency surgery for small bowel obstruction. METHODS: A retrospective cohort study including patients treated with emergency laparotomy for small bowel obstruction at a Copenhagen University Hospital (2009-2013). Complications were evaluated according to the Clavien-Dindo classification. RESULTS: A total of 323 patients were included. The overall 30-day morbidity and mortality rates were 28% and 13%, respectively. Six covariates were identified as independent risk factors associated with morbidity by multiple logistic regression analysis. The highest odds for morbidity were seen in patients with chronic nephropathy (Odds Ratio [OR] = 3.9; 95% CI 1.3-15.1), and in patients with a daily use of steroids (OR = 3.5; 95% CI 1.2-10.4). Five independent risk factors were associated with increased odds for mortality. Patients with low physical performance (OR = 3.4; 95% CI 1.3-8.2) or metabolic disorders (OR = 3.2; 95% CI 1.2-8.5) had the highest risk of mortality. CONCLUSIONS: Morbidity and mortality rates were high in this study compared with other studies. Several comorbid conditions were associated with morbidity and mortality. These results may aid the acute care surgeon in identifying patients with a high-risk for postoperative complications and fatal outcomes.

Telephone reminders reduced the non-attendance rate in a gastroenterology outpatient clinic.

INTRODUCTION: Non-attendance is a global health-care problem. The aim of the present study was 1) to investigate if a telephone reminder could reduce the non-attendance rate, 2) to study reasons for non-attendance and 3) to evaluate if a permanent implementation would be economically advantageous in a gastroenterology outpatient clinic like ours. METHODS: This was a comparative intervention study with a historical control group in a gastroenterology outpatient clinic. The study lasted six months. Patients with a scheduled appointment in the first three-month period received no reminder (control group, n = 2,705). Patients in the following three-month period were reminded by telephone one weekday in advance of their appointment, when possible (intervention group, n = 2,479). Non-attending patients in the intervention group received a questionnaire. Based on the results, a financial cost-benefit analysis was made. RESULTS: In the intervention group, 1,577 (64%) patients answered the reminder telephone call. The non-attendance rate was significantly lower in the intervention group (6.1%) than in the control group (10.5%) (p < 0.00001). Only 1.3% of the patients who answered the reminder turned out to be non-attendees. The most common explanation for non-attendance in the intervention group was forgetfulness (39%). The reminder telephone call was cost-effective. CONCLUSION: In this outpatient clinic, telephone reminders were cost-effective and significantly reduced the non-attendance rate by 43%.

[Genetic variation may influence the development of persistent postsurgical pain].

Persistent postsurgical pain is a major clinical problem. It is not fully understood why some patients develop persistent postsurgical pain while others do not. The genetic profile might play an important role in this development. In this article, we summarize the existing studies examining the effects of single nucleotide polymorphisms on the development of persistent postsurgical pain. The evidence in this area is sparse and the results are heterogeneous. Further studies are needed before firm conclusions can be made.
