TP6.2.8 Impact of patients’ characteristics on operative difficulty and clinical outcomes of laparoscopic cholecystectomy

Abstract Background Laparoscopic cholecystectomy (LC) is a common surgical procedure. Intraoperative findings are highly unpredictable and the operative difficulty varies from straightforward to very challenging procedures. Several studies described predictors of technical difficulty and graded intraoperative findings of LC, however none specifically reported on the effect of such factors on clinical outcomes. This study aims to evaluate the impact of patients’ preoperative characteristics on operative difficulty of LC and clinical outcomes. Methods Data of patients who underwent LC from 2015 to 2017 retrospectively analysed. Subjects were divided into four groups, according to Nassar’s classification of intraoperative difficulty. Differences in frequencies were evaluated with the Fisher’s exact test; logistic regression analysis was used to identify independent variables that were predictors of postoperative morbidity and length of stay. Results A total of 1069 patient were included. Male to female ratio of 1:2.5. Older age, male gender and comorbidities were associated with higher Nassar score (p < 0.0001); Nassar 3 and 4 were predictors of postoperative morbidity(P£0.01). The day case rate was 88.8% (Nassar 1), 86.1% (Nassar 2), 69.6% (Nassar 3), 62.3% (Nassar 4), respectively. Age of 60 and above(P£0.018), ASA 2 or 3(P£0.04) and Nassar 3, 4 (P£0.012), were predictors of increased conversion from day case to in-patient stay. Conclusion LC can be performed on a day case basis even when surgery is technically challenging. However, the need of in-patient stay can be predicted in comorbid old adult men with anticipated higher Nassar’s score.

Univariate Analyses

Purpose. The impact of an out-of-hours laparoscopic cholecystectomy on outcome is controversial. We sought to determine the association between an out-of-hours procedure and postoperative complications within 90 days. Methods. Between 2014 and 2016, 1553 laparoscopic cholecystectomies were performed. Therapeutic, operative, and outcome data were prospectively collected and analyzed. We defined out of hours as during weekends, national holidays, and daily between 5PM and 8AM. Results. Most patients operated on were female (n=988; 63.6%) and the majority of procedures were electives (n=1341; 86.3%). Although all procedures were performed with a laparoscopic intent, 42 (2.7%) were converted to open procedure. In total, 145 (9.3%) procedures were out of hours, all nonelective, and in most cases for acute cholecystitis (n=111; 7.1%). Overall, there were 212 complications in 191 patients (12.3%), most (n=153; 9.9%) classified as minor. The conversion rate in the out-of-hours group was significantly higher (9.7% vs 2.0%; p<0.001). While univariate analyses revealed out-of-hours procedure (OR=1.83; p=0.008) to be associated with an increased risk of complications, when controlling for confounding factors by multivariate analysis, this association was not found. However, operation by surgical staff (OR=1.71) and conversion to laparotomy (OR=3.74) were found to be independently associated with an increased risk of complications (both p<0.05), while an emergency procedure tended to be associated with postoperative morbidity (OR=1.82; p=0.069). Conclusion. An out-of-hours laparoscopic cholecystectomy was not found to be an independent risk factor for developing postoperative morbidity and time of day should therefore only be a relative contraindication.

A Prospective Study

Abstract Background Bile duct injury rates for laparoscopic cholecystectomy (LC) remain higher than during open cholecystectomy. The “culture of safety” concept is based on demonstrating the critical view of safety (CVS) and/or correctly interpreting intraoperative cholangiography (IOC). However, the CVS may not always be achievable due to difficult anatomy or pathology. Safety may be enhanced if surgeons assess difficulties objectively, recognise instances where a CVS is unachievable and be familiar with recovery strategies. Aims and methods A prospective study was conducted to evaluate the achievability of the CVS during all consecutive LC performed over four years. The primary aim was to study the association between the inability to obtain the CVS and an objective measure of operative difficulty. The secondary aim was to identify preoperative and operative predictors indicating the use of alternate strategies to complete the operation safely. Results The study included 1060 consecutive LC. The median age was 53 years, male to female ratio was 1:2.1 and 54.9% were emergency admissions. CVS was obtained in 84.2%, the majority being difficulty grade I or II (70.7%). Displaying the CVS failed in 167 LC (15.8%): including 55.6% of all difficulty grade IV LC and 92.3% of difficulty grade V. There were no biliary injuries or conversions. Conclusion All three components of the critical view of safety could not be demonstrated in one out of 6 consecutive laparoscopic cholecystectomies. Preoperative factors and operative difficulty grading can predict cases where the CVS may not be achievable. Adapting instrument selection and alternate dissection strategies would then need to be considered.

The Impact

Abstract Background The COVID-19 pandemic resulted in substantial delays to surgery among patients with symptomatic gallstones due to cessation of elective surgical procedures. As this exposed patients to a longer period of time during which complications from gallstones could develop, we hypothesised that the operative difficulty and complication rate of laparoscopic cholecystectomy (LC) increased following the first wave of the pandemic. Methods This was a retrospective cohort study of patients receiving emergency or elective LC at a single NHS trust comprising three sites. We included patients undergoing surgery in the pre-pandemic period (July-September 2019) and after resumption of elective surgical services following the first wave of the pandemic (July-September 2020). We compared data on operative duration, length of hospital stay, complications (bile leak, bile duct injury and mortality) and need for subtotal cholecystectomy. Categorical data are reported as n(%) and were compared with Fisher’s exact test. Continuous data are reported as median with interquartile range and compared with Mann-Whitney U Test. Results 220 patients were included; 106 in the pre-pandemic group and 114 in the pandemic group. There were no significant differences in median operative times between the pre-pandemic (91 (71-121 minutes) and post-first wave (86 (69-114) minutes) groups (p = 0.48). The proportion of prolonged operations (over two hours) was similar in the pre-pandemic and pandemic groups (50% versus 46%, respectively, p = 0.59). Median length of hospital stay was 0 days for both groups (pre-pandemic 0 (0-1) days; pandemic 0 (0-1) days, p = 0.42)). There were no significant differences in the rates of bile leak, bile duct injury, mortality, or the conversion to subtotal cholecystectomy. Conclusions Interruption of elective surgery following the first wave of the COVID-19 pandemic did not result in a discernible change in the technical difficulty or complication rate of LC at our centre. Longer term studies are required to assess the effect of prolonged delays to surgery and the impact of subsequent waves of the pandemic.

ABSTRACT Introduction: On Aug. 29, 2005, Hurricane Katrina made landfall along the Gulf Coast of the United States, resulting in the evacuation of more than 1.5 million people, including nearly 6000 physicians. This article examines the relocation patterns of physicians following the storm, determines the impact that the disaster had on their lives and practices, and identifies lessons learned. Methods: An Internet-based survey was conducted among licensed physicians reporting addresses within Federal Emergency Management Agency-designated disaster zones in Louisiana and Mississippi. Descriptive data analysis was used to describe respondent characteristics. Multivariate logistic regression was performed to identify the factors associated with physician nonreturn to original practice. For those remaining relocated out of state, bivariate analysis with x2 or Fisher exact test was used to determine factors associated with plans to return to original practice. Results: A total of 312 eligible responses were collected. Among disaster zone respondents, 85.6 percent lived in Louisiana and 14.4 percent resided in Mississippi before the hurricane struck. By spring 2006, 75.6 percent (n = 236) of the respondents had returned to their original homes, whereas 24.4 percent (n = 76) remained displaced. Factors associated with nonreturn to original employment included family or general medicine practice (OR 0.42, 95 percent CI 0.17–1.04; P = .059) and severe or complete damage to the workplace (OR 0.24, 95 percent CI 0.13–0.42; P < .001). Conclusions: A sizeable proportion of physicians remain displaced after Hurricane Katrina, along with a lasting decrease in the number of physicians serving in the areas affected by the disaster. Programs designed to address identified physician needs in the aftermath of the storm may give confidence to displaced physicians to return.

Abstract Background It is well established that single pill combination (SPC) therapies have the potential to improve patient adherence versus multi-pill regimens, thereby improving blood pressure control and clinical outcomes in populations with hypertension. Purpose To develop a microsimulation model, capturing different treatment pathways, to project the impact on clinical outcomes of using single pill combination therapies for the management of hypertension in five countries (Italy, Russia, China, South Korea and Mexico). Methods The model was designed to project health outcomes between 2020 and 2030 for populations with hypertension managed according to four different treatment pathways: current treatment practices [CTP], single drug with dosage titration first then sequential addition of other agents [start low and go slow, SLGS], free choice combination with multiple pills [FCC] and combination therapy in the form of a single pill [SPC]. Model inputs were derived from Global Burden of Disease 2017 dataset, including demographics, health status/risk factors, transition probabilities and treatment attributes/healthcare utilization, and the model incorporated real-world challenges to healthcare delivery such as access to care, SBP measurement error, adherence and therapeutic inertia. Simulated outcomes of mortality, incidence of chronic kidney disease (CKD), stroke and ischemic heart disease (IHD), and disability-adjusted life years (DALYs) due to these conditions were estimated for population of 1,000,000 simulated patients for each treatment pathway and country. Results SPC therapy was projected to improve health outcomes over SLGS, FCC and CTP over 10 years in all five countries. SPC was forecast to reduce mortality by 5.4% (Italy), 4.9% (Russia), 4.5% (China), 2.3% (South Korea) and 3.6% (Mexico) versus CTP and showed greater projected reductions in mortality than SLGS and FCC. DALYs were projected to be reduced with SPC therapy by between 5.7% (Italy) and 2.2% (South Korea) compared with CTP and reductions in the incidence of clinical events were also projected with SPC therapy, with decreases in the range of 11.5% (Italy) to 4.9% (South Korea) versus CTP. Conclusions Ten-year projections of clinical outcomes associated with different anti-hypertensive treatment pathways in five countries indicated that both combination therapies (FCC and SPC) are likely to reduce the disease burden of hypertension compared with conventional management approaches, with SPC showing the greatest overall benefits due to improved adherence.

Abstract Background As opposed to Staphylococcus. aureus bacteremia, there are no guidelines to recommend repeating blood cultures in Gram-negative bacilli bacteremia (GNB). Several studies have questioned the utility of follow-up blood cultures (FUBCs) in GNB, but the impact of this practice on clinical outcomes is not fully understood. Our aim was to study the practice of obtaining FUBCs in GNB at our institution and to assess it’s impact on clinical outcomes. Methods We conducted a retrospective, single-center study of adult patients, ≥ 18 years of age admitted with GNB between January 2017 and December 2018. We aimed to compare clinical outcomes in those with and without FUBCs. Data collected included demographics, comorbidities, presumed source of bacteremia and need for intensive care unit (ICU) admission. Presence of fever, hypotension /shock and white blood cell (WBC) count on the day of FUBC was recorded. The primary objective was to compare 30-day mortality between the two groups. Secondary objectives were to compare differences in 30-day readmission rate, hospital length of stay (LOS) and duration of antibiotic treatment. Mean and standard deviation were used for continuous variables, frequency and proportion were used for categorical variables. P-value < 0.05 was defined as statistically significant. Results 482 patients were included, and of these, 321 (67%) had FUBCs. 96% of FUBCs were negative and 2.8% had persistent bacteremia. There was no significant difference in 30-day mortality between those with and without FUBCs (2.9% and 2.7% respectively), or in 30-day readmission rate (21.4% and 23.4% respectively). In patients with FUBCs compared to those without FUBCs, hospital LOS was longer (7 days vs 5 days, P < 0.001), and mean duration of antibiotic treatment was longer (14 days vs 11 days, P < 0.001). A higher number of patients with FUBCs needed ICU care compared to those without FUBCs (41.4% and 25.5% respectively, P < 0.001) Microbiology of index blood culture in those with and without FUBCs Outcomes in those with and without FUBCs FUBCs characteristics Conclusion Obtaining FUBCs in GNB had no impact on 30-day mortality or 30-day readmission rate. It was associated with longer LOS and antibiotic duration. Our findings suggest that FUBCs in GNB are low yield and may not be recommended in all patients. Prospective studies are needed to further examine the utility of this practice in GNB. Disclosures All Authors: No reported disclosures

Abstract Background Altered pharmacokinetics in obese patients raise concerns over worse clinical outcomes. This study assessed whether obese patients receiving a beta-lactam (BL) have worse clinical outcomes compared to non-obese patients and to identify if therapeutic drug monitoring (TDM) may be beneficial. Methods This multi-center, retrospective cohort included hospitalized adults admitted from July 2015-July 2017 treated with a BL as definitive monotherapy against a Gram-negative bacilli for ≥72 hours. Patients were excluded if there was lack of source control or if polymicrobial infections required >1 antibiotic for definitive therapy. Patients were classified based on body mass index (BMI): non-obese (BMI ≤29.9 kg/m 2) and obese (BMI ≥30.0 kg/m 2). The primary outcome was clinical treatment failure, and secondary were hospital length of stay (LOS), inpatient all-cause mortality, and 30-day all-cause readmission. Results There were 257 (43.6%) obese patients and 332 (56.4%) non-obese patients included. The most common infections were urinary (50.9%) and respiratory (31.4%). Definitive treatment was driven by 3 rd generation cephalosporins (46.9%) and cefepime (44.7%). Treatment failure occurred in 131 (51%) obese patients and 109 (32.8%) non-obese patients (p<0.001). Obesity and respiratory source were independently associated with increased likelihood of treatment failure. Obese patients were hospitalized longer than non-obese patients (p=0.002), but no differences were found for all-cause mortality (p=0.117) or infection-related readmission (0=0.112). Conclusions Obese patients treated with BLs have higher rates of treatment failure and longer hospitalization periods than non-obese patients. Future studies are needed to assess the impact of TDM and specific dosing recommendations for targeted infection types.

Abstract Background There is a growing literature in support of the effectiveness of task-shared mental health interventions in resource-limited settings globally. However, despite evidence that effect sizes are greater in research studies than actual care, the literature is sparse on the impact of such interventions as delivered in routine care. In this paper, we examine the clinical outcomes of routine depression care in a task-shared mental health system established in rural Haiti by the international health care organization Partners In Health, in collaboration with the Haitian Ministry of Health, following the 2010 earthquake. Methods For patients seeking depression care betw|een January 2016 and December 2019, we conducted mixed-effects longitudinal regression to quantify the effect of depression visit dose on symptoms, incorporating interaction effects to examine the relationship between baseline severity and dose. Results 306 patients attended 2052 visits. Each visit was associated with an average reduction of 1.11 in depression score (range 0–39), controlling for sex, age, and days in treatment (95% CI −1.478 to −0.91; p < 0.001). Patients with more severe symptoms experienced greater improvement as a function of visits (p = 0.04). Psychotherapy was provided less frequently and medication more often than expected for patients with moderate symptoms. Conclusions Our findings support the potential positive impact of scaling up routine mental health services in low- and middle-income countries, despite greater than expected variability in service provision, as well as the importance of understanding potential barriers and facilitators to care as they occur in resource-limited settings.

Background: Tocilizumab is an interleukin-6 receptor antagonist hypothesized to blunt the uncontrolled immune response, cytokine release syndrome, in severe COVID-19 and prevent attributable morbidity and mortality. Objective: The objective of this study was to assess the impact of tocilizumab on clinical outcomes in COVID-19-associated cytokine release syndrome. Methods: Single-center, retrospective cohort study assessing sixty-nine adult patients receiving tocilizumab for suspected COVID-19 cytokine release syndrome. The primary outcome was change in WHO clinical status scale on day seven post-dose analyzed using the Wilcoxon signed rank test. Secondary outcomes assessed impact of timing of administration on clinical outcome. Safety analyses included development of neutropenia, thrombocytopenia, transaminitis, and sepsis within 7 days post-dose. Statistical analyses were conducted using Microsoft Excel. Results: No aggregate clinical change was found between day 0 and day 7. Eleven patients improved, twenty-seven worsened, and thirty-one showed no change. Clinical outcomes were weakly correlated with time from symptom onset (rs = 0.21; p = 0.08) or hospital admission (rs = -0.08; p = 0.49) to dose. In-hospital mortality was 63%. Sepsis was diagnosed in 21 patients, five of which were post-dose. Transaminitis, neutropenia, and thrombocytopenia occurred in seven, one, and six patients, respectively. Conclusion: Tocilizumab did not appear to influence clinical outcomes in our study population, irrespective of timing of administration. Adverse events were not considered drug-related.
