Association of Liver Resection and Visiting More Than One Commission on Cancer Hospital for Colorectal Cancer With Liver Metastasis.

INTRODUCTION: Despite the advances in treatment, there are low rates of liver metastasectomy for colorectal cancer with liver metastasis (CRLM) in the United States. The aim of this study was to investigate the association between likelihood of liver metastasectomy for CRLM and seeking care at >1 versus 1 Commission on Cancer (CoC) hospital. METHODS: We performed a retrospective analysis of the National Cancer Database (2011-2017) for patients with CRLM. Patients were grouped based on seeking care at 1 CoC hospital or >1 CoC hospital. An adjusted multivariable Poisson regression interaction analysis was used to evaluate likelihood of liver metastasectomy for CRLM according to race and whether care was sought at >1 CoC hospital. RESULTS: We identified 25,956 patients with CRLM without extra-hepatic disease. 23,088 (89.0%) patients visited 1 CoC hospital and 2868 (11.1%) visited >1 CoC hospital. Black patients were less likely to seek care at >1 CoC hospital (relative risk [RR] 0.68, confidence intervalCI 0.60-0.76, P < 0.001). Undergoing liver metastasectomy was associated with higher likelihood of seeking care at >1 CoC hospital (RR 1.27, CI 1.26-1.52, P < 0.001). Among patients who sought care at >1 CoC hospital, there was no significant difference between White and Black patients undergoing liver metastasectomy (RR 0.86, 95% CI 0.71-1.04, P = 0.11). CONCLUSIONS: Patients with CRLM who sought care at >1 CoC hospital were more likely to undergo a liver metastasectomy. Among White and Black patients who sought care at >1 CoC hospital, there was no difference in likelihood of undergoing a liver metastasectomy.

Determining Critical Topics for Undergraduate Surgical Education in Rwanda: Results of a Modified Delphi Process and a Consensus Conference.

Background Developing a contextually appropriate curriculum is critical to train physicians who can address surgical challenges in sub-Saharan Africa. An innovative modified Delphi process was used to identify contextually optimized curricular content to meet sub-Saharan Africa and Rwanda's surgical needs. Methods Participants were surgeons from East, Central, Southern, and West Africa and general practitioners with surgical experience. Delphi participants excluded or prioritized surgical topic areas generated from extensive grey and formal literature review. Surgical educators first screened and condensed identified topics. Round 1 screened and prioritized identified topics, with a 75% consensus cut-off based on the content validity index and a prioritization score. Topics that reached consensus were screened again in round 2 and re-prioritized, following controlled feedback. Frequencies for aggregate prioritization scores, experts in agreement, item-level content validity index, universal agreement and scale-level content validity index based on the average method (S-CVI/Ave) using proportion relevance, and intra-class correlation (ICC) (based on a mean-rating, consistency, two-way mixed-effects model) were performed. We also used arithmetic mean values and modal frequency. Cronbach's Alpha was also calculated to ascertain reliability. Results were validated through a multi-institution consensus conference attended by Rwanda-based surgical specialists, general practitioners, medical students, surgical educators, and surgical association representatives using an inclusive, participatory, collaborative, agreement-seeking, and cooperative, a priori consensus decision-making model. Results Two-hundred and sixty-seven broad surgical content areas were identified through the initial round and presented to experts. In round 2, a total of 247 (92%) content areas reached 75% consensus among 31 experts. Topics that did not achieve consensus consisted broadly of small intestinal malignancies, rare hepatobiliary pathologies, and transplantation. In the final round, 99.6% of content areas reached 75% consensus among 31 experts. The highest prioritization was on wound healing, fluid and electrolyte management, and appendicitis, followed by metabolic response, infection, preoperative preparation, antibiotics, small bowel obstruction and perforation, breast infection, acute urinary retention, testicular torsion, hemorrhoids, and surgical ethics. Overall, the consistency and average agreement between panel experts was strong. ICC was 0.856 (95% CI: 0.83-0.87). Cronbach's Alpha for round 2 was very strong (0.985, 95% CI: 0.976-0.991) and higher than round 1, demonstrating strong reliability. All 246 topics from round 4 were verbally accepted by 40 participants in open forum discussions during the consensus conference. Conclusions A modified Delphi process and consensus were able to identify essential topics to be included within a highly contextualized, locally driven surgical clerkship curriculum delivered in rural Rwanda. Other contexts can use similar processes to develop relevant curricula.

Decentralization and Regionalization of Surgical Care: A Review of Evidence for the Optimal Distribution of Surgical Services in Low- and Middle-Income Countries.

BACKGROUND: While recommendations for the optimal distribution of surgical services in high-income countries (HICs) exist, it is unclear how these translate to resource-limited settings. Given the significant shortage and maldistribution of surgical workforce and infrastructure in many low- and middle-income countries (LMICs), the optimal role of decentralization versus regionalization (centralization) of surgical care is unknown. The aim of this study is to review evidence around interventions aimed at redistributing surgical services in LMICs, to guide recommendations for the ideal organization of surgical services. METHODS: A narrative-based literature review was conducted to answer this question. Studies published in English between 1997 and 2017 in PubMed, describing interventions to decentralize or regionalize a surgical procedure in a LMIC, were included. Procedures were selected using the Disease Control Priorities' (DCP3) Essential Surgery Package list. Intervention themes and outcomes were analyzed using a narrative, thematic synthesis approach. Primary outcomes included mortality, complications, and patient satisfaction. Secondary outcomes included input measures: workforce and infrastructure, and process measures: facility-based care, surgical volume, and referral rates. RESULTS: Thirty-five studies were included. Nine (33%) of the 27 studies describing decentralization showed an improvement in primary outcomes. The procedures associated with improved outcomes after decentralization included most obstetric, gynecological, and family planning services as well as some minor general surgery procedures. Out of 8 studies on regionalization (centralization), improved outcomes were shown for trauma care in one study and cataract extraction in one study. CONCLUSION: Interventions aimed at decentralizing obstetric care to the district hospital and health center levels have resulted in mortality benefits in several countries. However, more evidence is needed to link service distribution to patient outcomes in order to provide recommendations for the optimal organization of other surgical procedures in LMICs. Considerations for the optimal distribution of surgical procedures should include the acuity of the condition for which the procedure is indicated, anticipated case volume, and required level of technical skills, resources, and infrastructure. These attributes should be considered within the context of each country.
