15091 Background: Cytoreductive sugery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are being increasingly employed in the managment of peritoneal-based malignancies. Depending on the treatment regimen, neutropenia (NP) is a common and potentially life-threatening early postoperative complication of HIPEC. However, little is known about the incidence or risk factors associated with HIPEC-induced NP. Methods: From January 1993 to October 2006, 120 CRS and HIPEC with mitomycin-c (MMC) were performed in 117 patients with appendiceal neoplasm. NP was defined as an absolute neutrophil count of < 1,000/mm3. Variables assessed as potential risk factors for HIPEC-induced NP included: age, sex, weight, BMI, BSA, splenectomy, dose of MMC (standardized for BSA and nonstandardized), percent of perfusate recovered, length of surgery, estimated blood loss, perioperative blood transfusion, and history of prior chemotherapy. Results: Total perfusate MMC doses ranged between 37.25 and 65 mg. The overall incidence of NP was 39.2%. The NP rates in female and male were 57.6% and 21.3%, respectively. Female sex, BMI, BSA, and the standardized dose of MMC were significantly associated with an increased risk of NP by univariable logistic regression. Female sex and standardized dose of MMC remained statistically significant for an increased risk of NP on multivariable logistic regression. The odds ratio (OR) of NP for females was 3.63 (95% CI: 1.54, 8.52); the OR of NP for a 1 mg/m2 increase in standardized MMC dose was 1.26 (95% CI: 1.11, 1.44). No other variables were identified as independent predictors of increased or decreased risk of NP. Compared to patients without NP, patients with NP had a higher rate of urinary tract infection (42.6% vs. 21.1%, p=0.01) and slightly higher length of stay (median: 24.0 days vs. 18.5 days, p=0.16). Conclusions: NP is a common complication after HIPEC with MMC . Female patients are at significantly increased risk for this complication. Risk of NP also increases with MMC dose standardized for BSA. With increasing interest in the use of CRS and HIPEC, understanding the risk factors for HIPEC-induced NP may facilitate reducing the morbidity associated with this procedure.

Abstract Background Mitomycin-C (MMC) is the most commonly used chemotherapeutic agent for hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery (CRS). However, MMC has a side effect of myelosuppression. This study aimed to evaluate the clinical manifestations and impact of MMC-induced neutropenia after CRS and HIPEC in colorectal cancer patients. Methods A total of 124 colorectal cancer patients who underwent CRS with HIPEC between March 2015 and January 2019 were evaluated. Patients with malignancies of non-colorectal origin, hospital stay longer than 60 days, peritoneal cancer index > 30, and complete cytoreduction score > 2 were excluded. MMC 35 mg/m2 was administered for 90 min at 41–43 °C. The patients were divided into three groups: no neutropenia, mild neutropenia (grade 1–2), and severe neutropenia (grade 3–4). Results In total, mild and severe neutropenia occurred in 30 (24.2%) and 48 (38.7%) patients, respectively. Age and body surface area were significantly different among the neutropenia groups. Severe neutropenia developed significantly earlier than mild neutropenia (6.9 days vs. 10.4 days, p < 0.001) and also lasted significantly longer (4.6 days vs. 2.5 days, p = 0.005). The rate of major postoperative complications was significantly higher in the severe neutropenia group than in the no and mild neutropenia groups (8.3% vs. 6.7% vs. 6.5%, p = 0.015) Conclusions Severe neutropenia starts earlier and lasts longer than mild neutropenia after CRS and HIPEC using an MMC triple method. The higher rate of major postoperative complications in patients with severe neutropenia highlights the importance of postoperative management during the neutropenia period.

28 Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) in addition to Cytoreductive surgery (CRS) has survival benefit observed in management of Peritoneal Carcinomatosis (PC) from Colo-rectal cancer (CRC)origin. We report the outcomes and prognostic factors of patients with CRC, who presented with PC and underwent CRS and HIPEC at King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia. Methods: Patients presented with PC from CRC origin and underwent CRS and HIPEC; from February 2009 to September 2015 were recruited. Results: 52 patients identified. A total of 55 CRS procedures were performed, where 3 patients underwent repeated CRS and HIPEC for tumor recurrence. All except 3 used mitomycin-C for HIPEC, the remaining received either melphalan (2 patients) or cisplatin plus mitomycin-C regimen (1 patient). Melphalan used for patients who underwent repeated HIPEC as 2nd line chemotherapeutic agent. Intraoperative Radiation therapy performed in 5 patients with tumor invading the surrounding structures, where performing a safe or complete resection was either technically difficult or carried high risk. Complication assessment by Clavien-Dindo score, 62 % grade (I-II), while 31% had grade (3–4). Two patients (3.6%) died postoperatively; both from sepsis. Respiratory complications were the most commonly encountered morbidities. The 5-year overall survival(OS) was 50% with disease free survival (DFS) 29.5%. Univariate analysis showed poor OS and DFS encountered in; Signet-ring tumors (p < 0.0001) for both, peritoneal cancer index (PCI) ≥ 6 (p < 0.0009) for both, completeness of cytoreduction(CC) score >1 (p < 0.0001) for both, and high 3-month postoperative carcinoembryonic antigen value (p <0.0001) for both. In multivariate analysis; DFS was significant for (PCI) ≥ 6 (p < 0.0131) and (CC) score >1 (p < 0.0031) while PCI > 6 was the only significant factor (p < 0.0030) for OS. Conclusions: Addition of HIPEC to CRS was safe, and improved survival in patient with peritoneal Carcinomatosis of colo-rectal origin. PCI and CC score are prognostic factors of survival, signet-ring subtype may not benefit of this procedure.

Objectives: Diabetic patients are often diagnosed with several comorbidities. The aim of the present study was to investigate the relationship between different combinations of risk factors and complications in diabetic patients. Research design and methods: We used a longitudinal, population-wide dataset of patients with hospital diagnoses and identified all patients (n = 195,575) receiving a diagnosis of diabetes in the observation period from 2003–2014. We defined nine ICD-10-codes as risk factors and 16 ICD-10 codes as complications. Using a computational algorithm, cohort patients were assigned to clusters based on the risk factors they were diagnosed with. The clusters were defined so that the patients assigned to them developed similar complications. Complication risk was quantified in terms of relative risk (RR) compared with healthy control patients. Results: We identified five clusters associated with an increased risk of complications. A combined diagnosis of arterial hypertension (aHTN) and dyslipidemia was shared by all clusters and expressed a baseline of increased risk. Additional diagnosis of (1) smoking, (2) depression, (3) liver disease, or (4) obesity made up the other four clusters and further increased the risk of complications. Cluster 9 (aHTN, dyslipidemia and depression) represented diabetic patients at high risk of angina pectoris “AP” (RR: 7.35, CI: 6.74–8.01), kidney disease (RR: 3.18, CI: 3.04–3.32), polyneuropathy (RR: 4.80, CI: 4.23–5.45), and stroke (RR: 4.32, CI: 3.95–4.71), whereas cluster 10 (aHTN, dyslipidemia and smoking) identified patients with the highest risk of AP (RR: 10.10, CI: 9.28–10.98), atherosclerosis (RR: 4.07, CI: 3.84–4.31), and loss of extremities (RR: 4.21, CI: 1.5–11.84) compared to the controls. Conclusions: A comorbidity of aHTN and dyslipidemia was shown to be associated with diabetic complications across all risk-clusters. This effect was amplified by a combination with either depression, smoking, obesity, or non-specific liver disease.

AbstractTreating patients with COVID-19 is expensive, thus it is essential to identify factors on admission associated with hospital length of stay (LOS) and provide a risk assessment for clinical treatment. To address this, we conduct a retrospective study, which involved patients with laboratory-confirmed COVID-19 infection in Hefei, China and being discharged between January 20 2020 and March 16 2020. Demographic information, clinical treatment, and laboratory data for the participants were extracted from medical records. A prolonged LOS was defined as equal to or greater than the median length of hospitable stay. The median LOS for the 75 patients was 17 days (IQR 13–22). We used univariable and multivariable logistic regressions to explore the risk factors associated with a prolonged hospital LOS. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated. The median age of the 75 patients was 47 years. Approximately 75% of the patients had mild or general disease. The univariate logistic regression model showed that female sex and having a fever on admission were significantly associated with longer duration of hospitalization. The multivariate logistic regression model enhances these associations. Odds of a prolonged LOS were associated with male sex (aOR 0.19, 95% CI 0.05–0.63, p = 0.01), having fever on admission (aOR 8.27, 95% CI 1.47–72.16, p = 0.028) and pre-existing chronic kidney or liver disease (aOR 13.73 95% CI 1.95–145.4, p = 0.015) as well as each 1-unit increase in creatinine level (aOR 0.94, 95% CI 0.9–0.98, p = 0.007). We also found that a prolonged LOS was associated with increased creatinine levels in patients with chronic kidney or liver disease (p < 0.001). In conclusion, female sex, fever, chronic kidney or liver disease before admission and increasing creatinine levels were associated with prolonged LOS in patients with COVID-19.

OBJECTIVE: To determine patient and perioperative characteristics associated with unexpected postoperative clinical deterioration as determined for the need of a postoperative emergency response team (ERT) activation. DESIGN: Retrospective case–control study. SETTING: Tertiary academic hospital. PARTICIPANTS: Patients who underwent general anaesthesia discharged to regular wards between 1 January 2013 and 31 December 2015 and required ERT activation within 48 postoperative hours. Controls were matched based on age, sex and procedure. MAIN OUTCOME MEASURES: Baseline patient and perioperative characteristics were abstracted to develop a multiple logistic regression model to assess for potential associations for increased risk for postoperative ERT. RESULTS: Among 105 345 patients, 797 had ERT calls, with a rate of 7.6 (95% CI, 7.1–8.1) calls per 1000 anaesthetics (0.76%). Multiple logistic regression analysis showed the following risk factors for postoperative ERT: cardiovascular disease (odds ratio [OR], 1.61; 95% CI, 1.18–2.18), neurological disease (OR, 1.57; 95% CI, 1.11–2.22), preoperative gabapentin (OR, 1.60; 95% CI, 1.17–2.20), longer surgical duration (OR, 1.06; 95% CI, 1.02–1.11, per 30 min), emergency procedure (OR, 1.54; 95% CI, 1.09–2.18), and intraoperative use of colloids (OR, 1.50; 95% CI, 1.17–1.92). Compared with control participants, ERT patients had a longer hospital stay, a higher rate of admissions to critical care (55.5%), increased postoperative complications, and a higher 30-day mortality rate (OR, 3.36; 95% CI, 1.73–6.54). CONCLUSION: We identified several patient and procedural characteristics associated with increased likelihood of postoperative ERT activation. ERT intervention is a marker for increased rates of postoperative complications and death.

Background. Antiepileptic drugs (AEDs) noncompliance is associated with increased risk of seizures and morbidity in seizure disorder patients. Objective. To identify risk factors that correlated to higher levels of morbidity, measured by emergency room (ER) utilization by seizure disorder members taking AED. Methods. Patients with primary or secondary diagnosis of seizures, convulsions, and/or epilepsy and prescribed AEDs during an 11-month period were included in the study. Variables were analyzed using multivariate statistical analysis including logistic regression. Results. The study identified 201 members. No statistical significance (NS) between age, gender, number of tablets, type of drug, or other risk factors was associated with increased mortality. Statistical significance resulted with medication compliance review of 0–14 days, 15–60 days, and 61+ days between refills. 68% of patients with ER visit had noncompliance refill between 0 and 14 days compared to 52% of patients in non-ER group (P=0.04). Contrastingly, 15% of ER group had refills within 15–60 days compared with 33% of non-ER group (P=0.01). There was NS difference between two groups when noncompliance was greater than 60 days (P=0.66). Conclusions. The study suggests that careful monitoring of pharmaceutical refill information could be used to identify AED noncompliance in epileptic patients.

Background: Very low birth weight (VLBW) babies are at increased risk of a number of complications both immediate and late. Worldwide it has been observed that these babies contribute to a significant extent to neonatal mortality and morbidity. Aim of the study was to study the risk factors contributing to mortality in VLBW babies and to evaluate the morbidity pattern in these infants.Methods: A retrospective analysis of data retrieved from the case records of VLBW babies admitted in the NICU of Kilpauk Medical College between January 2015 to December 2015. Out of the 2360 intramural babies admitted during the study period, 99 babies were less than 1500 gms. The risk factors for these babies were analyzed for their association with the outcome. Data were statistically analyzed.Results: In present study, we found that sex of the baby, gestational age, obstetric score, birth asphyxia, pulmonary haemorrhage, ROP and presence of shock were found to be associated with increased mortality. By logistic regression analysis it was observed that birth weight of the baby (p value 0.002), duration of stay (p value 0.0006), presence of shock (p<0.0001), were the risk factors significantly associated with poor outcome.Conclusions: Among the maternal and neonatal factors analyzed in the study using logistic regression analysis, birth weight, duration of hospital stay and presence of shock were significantly related to poor outcome. Of these presence of shock was the single most important factor that predicted increased mortality.
