Independent Predictors of In-Hospital Mortality in Elderly and Non-elderly Adult Patients Undergoing Emergency Admission for Hemorrhoids

Background The study explored determinants of mortality of admitted emergently patients with the primary diagnosis of hemorrhoids, during the years 2005-2014. Methods Demographics, clinical data, and outcomes were obtained from the National Inpatient Sample, 2005-2014, in elderly (65+ years) and non-elderly adult patients (18-64 years) with hemorrhoids who underwent emergency admission. Multivariable logistic regression model with backward elimination was used to identify predictors of mortality. Results 25 808 adult and 26 978 elderly patients were included. Female patients consisted of 42.5% and 59.3% in adult and elderly, respectively. 42 (.2%) adults died, of which 50% were female and 125 (.5%) elderly patients died, of which 60% were female. Mean (SD) age of the adult patients was 47.8 (11) years and in elderly patients was 78.7 (8) years. 82.2% and 85.7% had internal hemorrhoids in adult and elderly patients, respectively. 9326 (36.1%) adult and 7282 (27%) elderly patients underwent an operation. In the final multivariable logistic regression model for adult patients with operation, delayed operation and invasive diagnostic procedures increased the odds of mortality, whereas in elderly patients, delayed operation and frailty index were the risk factors of mortality. In both adults and elderly with no operation, increased hospital length of stay (HLOS) significantly increased the odds of mortality, and undergoing an invasive diagnostic procedure significantly decreased the odds of mortality. Conclusion In all operated patients, increased time to operation and undergoing an invasive diagnostic procedure were the risk factors for mortality. On the other hand, in non-operated emergency hemorrhoids patients, increased age and increased HLOS were the risk factors for mortality while undergoing an invasive diagnostic procedure decreased the odds of mortality.

Risk Factors of Mortality in Patients Hospitalized With Chronic Duodenal Ulcers

Background We aimed to identify risk factors of mortality in patients hospitalized with duodenal ulcers (DUs). Methods A National Inpatient Sample–based retrospective cohort study from 2005 to 2014 was conducted on patients undergoing emergency admission for chronic DUs. Demographics, clinical data, and outcomes were collected. Multivariable logistic regression model was applied to find the risk factors of mortality. Results 70 641 patients were included in this study, of which 30 525 (43%) were non-elderly (< 65 years) and 40 116 (57%) were elderly (65+ years) patients. 72% of non-elderly and 57% of elderly patients were males. Mortality rate of men vs women was similar in non-elderly group (1.9% vs 2%, respectively), whereas it significantly differed in elderly patients (4.5% vs 5.3%, respectively, P<.0001). Time to operation was 1.15 (1.83) days in survived vs 1.55 (3.86) days in deceased non-elderly patients ( P < .001). Time to operation was .85 (1.73) days in survived vs 1.79 (7.28) days in deceased elderly patients ( P < .001). In patients with operation, age, delayed operation, frailty, and presence of perforation were the main risk factors of mortality in both elderly and non-elderly patients. Invasive diagnostic procedure was shown as a protective factor in elderly patients. In the final model for patients with no operation, age, hospital length of stay, and frailty were the main risk factors of mortality in both elderly and non-elderly patients. Invasive diagnostic procedure was revealed as a protective factor in all patients as well. Conclusion Early operation in patients with DU requiring surgical intervention is essential to improve the outcomes.

Return to work: does cardiac rehabilitation make a difference? Danish nationwide register-based study

Aim: to assess whether participation in cardiac rehabilitation affects the probability of returning to work after ischaemic heart disease. Methods: the study population consisted of 24,509 patients (18–70 years of age) discharged from an inpatient admission at a Danish hospital during 2014–2018 and who were working before their admission. Only patients with a percutaneous coronary intervention or coronary artery bypass grafting surgery procedure and ICD-10 codes I20–I25 as their main diagnosis or ICD-10 codes I21, I240, I248 or I249 as secondary diagnosis during an emergency admission were included. Exposure was defined as participation in cardiac rehabilitation ( N = 15,742), and binary indicator of being at work in the last week of a given month were used as primary outcomes. Coarsened exact matching (CEM) of exposed and unexposed patients was used to reduce selection bias. Logistic regression models were applied on the matched population ( N = 15,762). Results: Less deprived and less comorbid patients were more likely to receive cardiac rehabilitation. CEM succeeded in arriving at a population where this selection was reduced and in this population we found that patients who received cardiac rehabilitation had a lower probability of returning to work after 3 months (OR 0.81, 95%CI: 0.77–0.84), a higher but insignificant probability after 6 (OR 1.02, 95%CI: 0.97–1.08), and a higher probability after 9 (OR 1.08, 95%CI: 1.02–1.15) and 12 months (OR 1.20, 95%CI: 1.13–1.28). Conclusions: Deprived and comorbid patients have lower use of cardiac rehabilitation. In a matched population where this bias is reduced, cardiac rehabilitation will increase the probability of returning to work.

Effect of the COVID-19 pandemic on complications and mortality of patients with cardiac surgery

Objectives The purpose of this study was to assess changes in cardiovascular disease severity, types, postoperative complications and prognosis during the COVID-19 pandemic and to explore possible influencing factors. Methods A total of 422 patients were enrolled in this study, and hospitalization and short-term follow-up data were retained. The patient population included 273 men and 149 women. Patients had a median (IQR) age of 54 (45–62) years and were divided into an observation group (130) and a control group (292), primarily according to severity of disease, disease types, baseline indexes, biochemical indexes, cardiac function indexes, complications and prognosis. Results During the COVID-19 pandemic, compared with the same period last year, there was a significant increase in patients with aortic dissection (27.69% vs 5.82%), a significant decrease in patients with valvular heart disease (43.08% vs 66.78%), and significantly increased emergency admission (50.00% vs 21.23%) and severity (54.62% vs 27.40%). Family company (76.37% vs 64.62%) was decreased, EuroSCORE [6.5 (2–9) vs 2 (0–5)] score, Pro-BNP [857.50 (241.00–2222.50) vs 542.40 (113.45–1776.75)] ng/L, six months mortality rate (18.46% vs 8.90%), and postoperative complications, including infected patients, atelectasis, pulmonary edema, and so on were increased, with longer length of stay in the ICU and hospital in COVID-19 pandemic. Survival analysis curve further demonstrated that it had an impact on the deaths of patients during the COVID-19 pandemic period. Through ROC analysis of the death factors of patients, it was concluded that Family company affected the death of patients, and the area under the curve was 0.654 (P < 0.05). Conclusions In this study, we found that the admission rate of critically ill patients with cardiovascular disease, complications of cardiac surgery, and short-term mortality of patients all exhibited a short-term increase, family company may be a risk factors for short-term mortality, that may be related to public pressure caused by the COVID-19 pandemic.

O-OGC02 Stage Migration in Newly Diagnosed Oesophago-gastric Cancer during the first wave of COVID-19 Pandemic

Background Covid-19 has significantly disrupted elective and emergency health care provision including cancer care within the UK. The aim of the study was to investigate the impact of the pandemic on the staging of oesophago-gastric cancers at presentation, determine the time delay in performing gastroscopy and the multidisciplinary team (MDT) treatment outcomes. Methods A retrospective cohort study of all newly diagnosed oesophago-gastric cancers (adenocarcinoma and squamous cell carcinoma) in a single regional MDT was performed between 1st October 2019 and 30th September 2020. Electronic records were interrogated and patients dichotomised into two groups with those presenting before the introduction of the UK national lockdown of 23rd March 2020 compared to those presenting post-lockdown. Results 349 new oesophago-gastric cancer patients were discussed in the MDT (192 pre-lockdown versus 157 post-lockdown). Demographics were evenly matched between the two groups. More patients presented as an emergency admission post-lockdown (28.0% vs 12.5%, p &lt; 0.001). Median waiting time for gastroscopy was longer post-lockdown (23 vs 14 days, p = 0.035). Metastatic disease at presentation was more frequent post-lockdown (47.8% vs 33.3%, p = 0.008). Overall, more patients had a palliative rather than curative treatment intent post-lockdown (71.3% vs 57.8%, p = 0.005). Conclusions The Covid-19 pandemic has had a significant negative effect on the stage of oesophago-gastric cancers at presentation. This has translated into more patients receiving palliative treatment and ultimately having a poorer prognosis. This study highlights the importance of maintaining cancer services during the Covid-19 pandemic.

O-BN06 A Proposed Difficulty Grading System for Laparoscopic Bile Duct Exploration. Benefits to Practice and Research

Background A gap remains between the mounting evidence for single session management of bile duct stones and the obstacles to wider adoption of this approach. The practice of laparoscopic bile duct exploration (LCBDE) is limited not only by the availability of training opportunities and adequate equipment but also by the perception that the technique is difficult and requires a high skill-set. The aim of this analysis is to compare the preoperative and operative characteristics and the postoperative outcomes in easy vs. difficult LCBDE in a large consecutive series, according to a proposed 5 grade classification. Methods 1326 LCBDEs were graded according to the location, number and size of ductal stones, retrieval techniques used, utilisation of choledochoscopy and specific biliary pathologies encountered. The cohort was divided into two groups: easy (Grades I A&B, and Grade II A&B, requiring transcystic or transductal exploration for up to 15 stones the largest being 15mm) and difficult (Grades III A&B, for over 15 stones or intrahepatic stones of any size needing transcystic choledochoscopy, IV and V with Mirizzi Syndrome, impacted stones, and ducts needing stenting, conversion or bilioenteric anastomosis). Various outcome parameters were compared. Results Age, sex, obesity and previous biliary admissions had no effect on operative difficulty. Emergency admission, obstructive jaundice, previous ERCP and dilated CBD were predictive of difficult explorations. 78.3% of patients with acute cholecystitis or pancreatitis, 37 % of jaundice and 46% of cholangitis had easy explorations. Transcystic stone retrieval was possible in 77.7% of easy explorations and choledochotomy required in 62.3% of difficult explorations (vs. 33.6% in the whole series). Choledochoscopy was utilised in 23.4% of Grades I&II vs. 98% in difficult explorations. As expected more biliary drains, stenting, bilio-enteric anastomosis, conversions, operative time, biliary-related complications, hospital stay, readmissions and retained stones increased with difficulty. Grades I&II patients had 2 or more hospital episodes in 26.5% vs. 41.2% for grades III to V, the median presentation to resolution interval increasing from 1 to 3 weeks. There were 2 deaths in difficulty Grade V and one in Grade IIB. Conclusions Difficulty grading of LCBDE is a useful tool of predicting outcomes. It facilitates comparison between studies and fair assessment of training. LCBDEs are easy in 72% and of these 77% can be completed transcystically. It is hoped this will encourage more units to adopt single session management of bile duct stones through establishing referral protocols, developing and refining the skills through training and acquiring the necessary equipment.

P.225 Factors Contributing to Prolonged Length of Stay in Adults Undergoing Spine Surgery: Results from a Quaternary Spinal Care Center

Background: Prolonged length of stay (LOS) is associated with increased resource utilization and worse outcomes. The goal of this study is identifying patient, surgical and systemic factors associated with prolonged LOS overall and per diagnostic category for adults admitted to a quaternary spinal care center. Methods: We performed a retrospective analysis on 13,493 admissions from 2006 to 2019. Factors analyzed included patient age, sex, emergency vs elective admission, diagnostic category (degenerative, deformity, oncology, trauma), presence of neurological deficits in trauma patients, ASIA score, operative management and duration, blood loss, and adverse events (AEs). Univariate and multivariate analyses determined factors associated with prolonged LOS. Results: Overall mean LOS (±SD) was 15.80 (±34.03) days. Through multivariate analyses, predictors of prolonged LOS were advanced age (p<0.001), emergency admission (p<0.001), advanced ASIA score (p<0.001), operative management (p=0.043), and presence of AEs (p<0.001), including SSI (p=0.001), other infections (systemic and UTI) (p<0.001), delirium (p=0.006), and pneumonia (p<0.001). The effects of age, emergency admission, and AEs on LOS differed by diagnostic category. Conclusions: Understanding patient and disease factors that affect LOS provides opportunities for QI intervention and allows for an informed preoperative discussion with patients. Future interventions can be targeted to maximize patient outcomes, optimize care quality, and decrease costs.
