AbstractBackgroundAdhesive small bowel obstruction (ASBO) severity has been associated with important clinical outcomes. However, the impact of ASBO severity on hospitalization cost is unknown. The American Association for the Surgery of Trauma (AAST) developed an Emergency General Surgery (EGS) disease severity grading system for ASBO. We stratified patients’ ASBO severity and captured hospitalization costs hypothesizing that increased disease severity would correlate with greater costs.MethodsThis was a single‐center study of hospitalized adult patients with SBO during 2015–2017. Clinical data and estimated total cost (direct + indirect) were abstracted. AAST EGS grades (I–IV) stratified disease severity. Costs were normalized to the median grade I cost. Univariate and multivariate analyses evaluated the relationship between normalized cost and AAST EGS grade, length of hospital and ICU stay, operative time, and Charlson comorbidity index.ResultsThere were 214 patients; 119 (56%) were female. AAST EGS grades included: I (62%, n = 132), II (23%, n = 49), III (7%, n = 16), and IV (8%, n = 17). Relative to grade I, median normalized cost increased by 1.4‐fold for grade II, 1.6‐fold for grade III, and 4.3‐fold for grade IV disease. No considerable differences in patient comorbidity between grades were observed. Pair‐wise comparisons demonstrated that grade I disease cost less than higher grades (corrected p < 0.001). Non‐operative management was associated with lower normalized cost compared to operative management (1.1 vs. 4.5, p < 0.0001). In patients who failed non‐operative management, normalized cost was increased 7.2‐fold. Collectively, the AAST EGS grade correlated well with cost (Spearman's p = 0.7, p < 0.0001). After adjustment for covariates, AAST EGS grade maintained a persistent relationship with cost.ConclusionIncreasing ASBO severity is independently associated with greater costs. Efforts to identify and mitigate costs associated with this burdensome disease are warranted.Level of evidenceIII, economic/decision.
Mental and Physical Workloads in a Competitive Laparoscopic Skills Training Environment
Surgical trainees undergo demanding training to achieve high surgical task proficiency. Abounding clinical and educational responsibilities mandate efficient and effective training. This research measured resident workload during laparoscopic skills training to identify excessive workload and how workload impacted task performance. Twenty-eight surgical trainees performed a standardized surgical training task and completed a workload questionnaire while observers measured physiological stress, posture risk assessment, and task performance. Participants self-reported mental demands, physical demands, temporal demands, performance, effort, and frustration. Effort (12±4) and frustration (12±5) were the highest subscales while physical demand (8±4) was the lowest. All participants were observed performing the task in at-risk postures, with 21% exhibiting risk levels requiring immediate intervention. Physical demand was associated with posture risk assessment scores (p<0.05). Mental demand was positively (R 2 =0.20, p<0.05) and frustration was negatively (R 2 =0.18, p<0.05) associated with skin conductance range. A point increase in physical demand was associated with a six second increase in performance time (β=6.0, p=0.01). These results support the fact that human factors and ergonomic tools can be used to relate surgical skills performance with workload, stress, and posture risks.
