ABSTRACT

INTRODUCTION: Surgical societies provide a plethora of resources for trainees; however, these opportunities are often underused due to suboptimal guidance, sponsorship, or mentorship. Here, we present the Society of Asian Academic Surgeons (SAAS) experience in enhancing the trainee experience and engagement in a surgical society focused on professional development. MATERIALS AND METHODS: We conducted an interactive idea-generating session during the 2022 SAAS Conference with all Associate Members (trainees) present in Honolulu, HI. Recurrent themes, concepts, and ideas/suggestions were carefully considered when planning the next SAAS Conference in Baltimore, MD. We employed a more targeted approach to trainee engagement at the 2023 SAAS Conference, with breakout sessions geared toward various levels of trainees, in addition to increased social events and networking opportunities. We obtained feedback from trainees in attendance through an electronic survey and informal conversations with faculty and Associate Members. RESULTS: Opportunities for surgical subspecialty networking was the most well-received portion of our formal Career Development program. The majority of trainees in attendance were medical students or junior residents who valued the exposure to junior faculty and those in leadership positions at academic institutions. The addition of a group text for easy communication among trainees and informal social activities for Associate Member networking among themselves were crucial in improving the overall conference experience. CONCLUSIONS: Opportunities to maximize trainee engagement in surgical societies are heightened during in-person conferences. Targeted session topics, guided networking opportunities, and creating channels for easier communication along with more social events have enhanced the overall experience for aspiring and current surgical trainees.

ABSTRACT

OBJECTIVES: The aim of this study was to assess the 1-year safety and effectiveness of HBV Nucleic Acid Test positive (HBV NAT+) allografts in seronegative kidney transplant (KT) and liver transplant (LT) recipients. SUMMARY BACKGROUND DATA: Despite an ongoing organ shortage, the utilization of HBV NAT+ allografts into seronegative recipients has not been investigated. METHODS: From January 2017 to October 2020, a prospective cohort study was conducted among consecutive KT and LT recipients at a single institution. Primary endpoints were post-transplant HBV viremia, graft and patient survival. RESULTS: With median follow-up of 1-year, there were no HBV-related complications in the 89 HBV NAT+ recipients. Only 9 of 56 KTs (16.1%) and 9 of 33 LTs (27.3%) experienced post-transplant HBV viremia at a median of 185 (KT) and 269 (LT) days postoperatively. Overall, viremic episodes resolved to undetected HBV DNA after a median of 80 days of entecavir therapy in 16 of 18 recipients. Presently, 100% of KT recipients and 93.9% of LT recipients are HBV NAT- with median follow-up of 13 months, whereas 0 KT and 8 LT (24.2%) recipients are HBV surface antigen positive indicating chronic infection. KT and LT patient and allograft survival were not different between HBV NAT+ and HBV NAT- recipients (P > 0.05), whereas HBV NAT+ KT recipients had decreased waitlist time and pretransplant duration on dialysis (P < 0.01). CONCLUSIONS: This is the largest series describing the transplantation of HBV NAT+ kidney and liver allografts into HBV seronegative recipients without chronic HBV viremia or decreased 1-year patient and graft survival. Increasing the utilization of HBV NAT+ organs in nonviremic recipients can play a role in decreasing the national organ shortage.

ABSTRACT

PURPOSE: Previous studies have suggested axillary lymph node dissection (ALND) can be omitted in early breast cancer patients undergoing mastectomy with positive lymph nodes (LNs). We assessed the national utilization of ALND and overall survival (OS) for larger, locally advanced tumors in patients undergoing mastectomy with positive LNs. METHODS: The National Cancer Database from 2006 to 2016 was queried for mastectomy patients with clinical T3/T4, N0 tumors, and 1-2 positive LNs. Trends and outcomes for ALND were compared to sentinel lymph node biopsy (SLNB) alone. RESULTS: Thousand nine hundred and seventeen women were included. The proportion of ALND decreased from 70% pre-Z0011 to 52% post-Z0011. On Kaplan-Meier analysis, ALND had better OS compared to SLNB alone (p < 0.01). On multivariate analysis, age (p < 0.01), chemotherapy (p < 0.01), and hormonal therapy (p < 0.01) were associated with better OS. In patients who received adjuvant radiation therapy (ART) ALND improved OS on multivariate analysis (p < 0.01). CONCLUSION: This is the first large database study to demonstrate a national trend to forego ALND in mastectomy patients with large or locally advanced tumors (T3/T4abc) and 1-2 positive lymph nodes. This study suggests a survival benefit for ALND, particularly in patients receiving ART. Careful consideration and further investigations should be performed prior to omitting ALND this patient population.

ABSTRACT

As the SARS-COV-2 pandemic created the need for social distancing and the implementation of nonessential travel bans, residency and fellowship programs have moved toward a web-based virtual process for applicant interviews. As part of the Society of Asian Academic Surgeons 5th Annual Meeting, an expert panel was convened to provide guidance for prospective applicants who are new to the process. This article provides perspectives from applicants who have successfully navigated the surgical subspecialty fellowship process, as well as program leadership who have held virtual interviews.

ABSTRACT

The increasing obesity epidemic has major implications in the realm of transplantation. Patients with obesity face barriers in access to transplant and unique challenges in perioperative and postoperative outcomes. Because of comorbidities associated with obesity, along with the underlying end-stage organ disease leading to transplant candidacy, these patients may not even be referred for transplant evaluation, much less be waitlisted or actually undergo transplant. However, the use of bariatric surgery in this population can help optimize the transplant candidacy of patients with obesity and end-stage organ disease and improve perioperative and postoperative outcomes. We review the impact of obesity on kidney, liver, and cardiothoracic transplant candidates and recipients and explore potential interventions to address obesity in these populations.

ABSTRACT

Simultaneous liver-kidney transplantation (SLKT) is indicated for patients with end-stage liver disease (ESLD) and concurrent renal insufficiency. En bloc SLKT is an alternative to traditional separate implantations, but studies comparing the two techniques are limited. The en bloc technique maintains renal outflow via donor infrahepatic vena cava and inflow via anastomosis of donor renal artery to donor splenic artery. Comparison of recipients of en bloc (n = 17) vs traditional (n = 17) SLKT between 2013 and 2017 was performed. Recipient demographics and comorbidities were similar. More recipients of traditional SLKT were dialysis dependent (82.4% vs 41.2%, P = .01) with lower baseline pretransplant eGFR (14 vs 18, P = .01). En bloc SLKT was associated with shorter kidney cold ischemia time (341 vs 533 minutes, P < .01) and operative time (374 vs 511 minutes, P < .01). Two en bloc patients underwent reoperation for kidney allograft inflow issues due to kinking and renal steal. Early kidney allograft dysfunction (23.5% in both groups), 1-year kidney graft survival (88.2% vs 82.4%, P = 1.0), and posttransplantation eGFR were similar between groups. In our experience, the en bloc SLKT technique is safe and feasible, with comparable outcomes to the traditional method.

ABSTRACT

BACKGROUND: Postoperative complications (POCs) are associated with worse oncologic outcomes in various cancer histologies. The impact of POCs on the survival of patients with appendiceal or colorectal cancer after cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is unknown. METHODS: The US HIPEC Collaborative (2000-2017) was reviewed for patients who underwent CCR0/1 CRS/HIPEC for appendiceal/colorectal cancer. The analysis was stratified by noninvasive appendiceal neoplasm versus invasive appendiceal/colorectal adenocarcinoma. The POCs were grouped into infectious, cardiopulmonary, thromboembolic, and intestinal dysmotility. The primary outcomes were overall survival (OS) and recurrence-free survival (RFS). RESULTS: Of the 1304 patients, 33% had noninvasive appendiceal neoplasm (n = 426), and 67% had invasive appendiceal/colorectal adenocarcinoma (n = 878). In the noninvasive appendiceal cohort, POCs were identified in 55% of the patients (n = 233). The 3-year OS and RFS did not differ between the patients who experienced a complication and those who did not (OS, 94% vs 94%, p = 0.26; RFS, 68% vs 60%, p = 0.15). In the invasive appendiceal/colorectal adenocarcinoma cohort, however, POCs (63%; n = 555) were associated with decreased 3-year OS (59% vs 74%; p < 0.001) and RFS (32% vs 42%; p < 0.001). Infectious POCs were the most common (35%; n = 196). In Multivariable analysis accounting for gender, peritoneal cancer index (PCI), and incomplete resection (CCR1), infectious POCs in particular were associated with decreased OS compared with no complication (hazard ratio [HR] 2.08; p < 0.01) or other types of complications (HR, 1.6; p < 0.01). Similarly, infectious POCs were independently associated with worse RFS (HR 1.61; p < 0.01). CONCLUSION: Postoperative complications are associated with decreased OS and RFS after CRS/HIPEC for invasive histology, but not for an indolent disease such as noninvasive appendiceal neoplasm, and this association is largely driven by infectious complications. The exact mechanism is unknown, but may be immunologic. Efforts must target best practices and standardized prevention strategies to minimize infectious postoperative complications.

ABSTRACT

BACKGROUND: No guidelines exist for surveillance following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for appendiceal and colorectal cancer. The primary objective was to define the optimal surveillance frequency after CRS/HIPEC. METHODS: The U.S. HIPEC Collaborative database (2000-2017) was reviewed for patients who underwent a CCR0/1 CRS/HIPEC for appendiceal or colorectal cancer. Radiologic surveillance frequency was divided into two categories: low-frequency surveillance (LFS) at q6-12mos or high-frequency surveillance (HFS) at q2-4mos. Primary outcome was overall survival (OS). RESULTS: Among 975 patients, the median age was 55 year, 41% were male: 31% had non-invasive appendiceal (n = 301), 45% invasive appendiceal (n = 435), and 24% colorectal cancer (CRC; n = 239). With a median follow-up time of 25 mos, the median time to recurrence was 12 mos. Despite less surveillance, LFS patients had no decrease in median OS (non-invasive appendiceal: 106 vs. 65 mos, p < 0.01; invasive appendiceal: 120 vs. 73 mos, p = 0.02; colorectal cancer [CRC]: 35 vs. 30 mos, p = 0.8). LFS patients had lower median PCI scores compared with HFS (non-invasive appendiceal: 10 vs. 19; invasive appendiceal: 10 vs. 14; CRC: 8 vs. 11; all p < 0.01). However, on multivariable analysis, accounting for PCI score, LFS was still not associated with decreased OS for any histologic type (non-invasive appendiceal: hazard ratio [HR]: 0.28, p = 0.1; invasive appendiceal: HR: 0.73, p = 0.42; CRC: HR: 1.14, p = 0.59). When estimating annual incident cases of CRS/HIPEC at 375 for non-invasive appendiceal, 375 invasive appendiceal and 4410 colorectal, LFS compared with HFS for the initial two post-operative years would potentially save $13-19 M/year to the U.S. healthcare system. CONCLUSIONS: Low-frequency surveillance after CRS/HIPEC for appendiceal or colorectal cancer is not associated with decreased survival, and when considering decreased costs, may optimize resource utilization.

ABSTRACT

BACKGROUND: For patients with peritoneal carcinomatosis undergoing cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC), incomplete cytoreduction (CCR2/3) confers morbidity without survival benefit. The aim of this study is to identify preoperative factors which predict CCR2/3. METHODS: All patients who underwent curative-intent CRS/HIPEC of low/high-grade appendiceal, colorectal, or peritoneal mesothelioma cancers in the 12-institution US HIPEC Collaborative from 2000 to 2017 were included (n = 2027). The primary aim is to create an incomplete-cytoreduction risk score (ICRS) to predict CCR2/3 CRS utilizing preoperative data. ICRS was created from a randomly selected cohort of 50% of patients (derivation cohort) and verified on the remaining patients (validation cohort). RESULTS: Within our derivation cohort (n = 998), histology was low-grade appendiceal neoplasms in 30%, high-grade appendiceal tumor in 41%, colorectal tumor in 22%, and peritoneal mesothelioma in 8%. CCR0/1 was achieved in 816 patients and CCR 2/3 in 116 patients. On multivariable analysis, preoperative factors associated with incomplete cytoreduction were male gender [odds ratio (OR) 3.4, p = 0.007], presence of ascites (OR 2.8, p = 0.028), cancer antigen (CA)-125 ≥ 40 U/mL (OR 3.4, p = 0.012), and carcinoembryonic antigen (CEA) ≥ 4.2 ng/mL (OR 3.2, p = 0.029). Each preoperative factor was assigned a score of 0 or 1 to form an ICRS from 0 to 4. Scores were grouped as zero (0), low (1-2), or high (3-4). Incidence of CCR2/3 progressively increased by risk group from 1.6% in zero to 13% in low and 39% in high. When ICRS was applied to the validation cohort (n = 1029), this relationship was maintained. CONCLUSION: The incomplete cytoreduction risk score incorporates preoperative factors to accurately stratify the risk of CCR2/3 resection in CRS/HIPEC. This score should not be used in isolation, however, to exclude patients from surgery.

ABSTRACT

BACKGROUND: The ACOSOG Z0011 trial has essentially eliminated axillary lymph node dissection (ALND) in breast conserving therapy (BCT) patients with clinical T1/T2 and 1-2 positive sentinel lymph nodes (SLNs). Currently, ALND is recommended for positive SLNs unless ACOSOG Z0011 criteria are applicable. We aimed to assess the national trends and axillary management before and after the publication of ACOSOG Z0011 for larger tumors. METHODS: An IRB-approved study evaluated the National Cancer Database from 2006 to 2016. Women with clinical T3/T4, N0 who otherwise fit ACOSOG Z0011 criteria were included. Neoadjuvant systemic therapy or known nodal disease was excluded. Clinicopathologic data were compared between two timeframes based on ACOSOZ Z0011 publication and by axillary management. Patients were categorized into SLNB alone (1-5 lymph nodes examined) and ALND (≥10 lymph nodes examined) groups. RESULTS: A total of 230 women fit inclusion criteria, of whom 36% underwent ALND. ALND use decreased from 54% in 2006 to 14% in 2016 (P < 0.01). Comparing ALND to SLNB alone within the pre-Z0011 era, comprehensive community cancer programs had higher proportions of ALND, whereas academic centers had higher rates of SLND alone (P = 0.03). Comparing similar axillary management between eras, SLNB-alone patients in the post-Z0011 era had higher pT and pN stages, were less likely to be Her2 positive, and were more likely to receive systemic treatment. CONCLUSIONS: There is a national trend to forgo ALND in women who have tumors larger than those included in the Z0011 criteria without any clear clinicopathologic indications.

ABSTRACT

BACKGROUND: Proximal (duodenal) small bowel adenocarcinomas have a worse prognosis than distal (jejuno-ileal) tumors, but differences in patient, tumor, and treatment factors between locations remain unclear. METHODS: Patients in the National Cancer Database with surgically resected pathologic stage I-IV small bowel adenocarcinomas between 2004 and 2015 were analyzed. Clinical stage IV patients were excluded. RESULTS: Proximal tumors (n = 3767) were more likely to be higher grade (OR 1.52, CI 1.22-1.85 for moderately; OR 1.83, CI 1.49-2.33 for poorly differentiated, P < 0.01 for both) and have positive lymph nodes (OR 2.04, CI 1.30-3.23, P < 0.01), while distal tumors (n = 3252) were likely to be larger (OR 1.31, CI 1.07-1.60 for size > 5 cm, P < 0.01). Proximal tumors were associated with worse overall survival (OS) and stage-specific survival compared with distal tumors (all P < 0.01). Cox regression analysis of the entire cohort showed worse survival with community versus academic cancer programs, higher comorbidity scores, pathologic stage IV, poorly differentiated histology, positive nodal or margin status, and proximal location, while female gender, larger tumor size, and chemotherapy predicted better survival. On separate Cox regression analyses of each location, neoadjuvant chemotherapy was associated with better OS in the proximal cohort (HR 0.70, CI 0.55-0.88, P < 0.01), while adjuvant chemotherapy was associated with better OS for both proximal (HR 0.49, CI 0.42-0.57, P < 0.01) and distal tumors (HR 0.68, CI 0.57-0.81, P < 0.01). CONCLUSIONS: Proximal small bowel adenocarcinomas are associated with worse overall and stage-specific survival. This may be due to tumor biologic differences as proximal tumors were more likely to have higher grade. Future studies should further investigate differences between proximal and distal tumors to guide targeted treatment algorithms.

ABSTRACT

OBJECTIVE: This study assesses the impact of a telemedicine-based home management program (THMP) on patient adherence, hospital readmissions, and quality of life (QOL) after liver transplantation (LT). SUMMARY OF BACKGROUND DATA: Telemedicine interventions represent an opportunity to personalize care and can lead to improved adherence and patient satisfaction. However, there is limited data on impact of these interventions on outcomes after LT. Therefore, we conducted the first randomized controlled trial (RCT) of a THMP compared to standard of care (SOC) after LT. METHODS: One hundred six consecutive LT recipients were randomized (1:1) to 1 of 2 posttransplant care strategies: SOC or THMP. The THMP included an electronic tablet and bluetooth devices to support daily text messages, education videos, and video FaceTime capability; data was cyber-delivered into our electronic medical record daily. Endpoints were THMP participation, 90-day hospital readmission rate, and QOL. RESULTS: One hundred patients completed the study with 50 enrolled in each arm. Participation and adherence with telemedicine was 86% for basic health sessions (vital sign recording), but only 45% for using messaging or FaceTime. The THMP group had a lower 90-day readmission rate compared to SOC (28% vs 58%; P = 0.004). The THMP cohort also showed improved QOL in regards to physical function (P = 0.02) and general health (P = 0.05) at 90 days. CONCLUSIONS: To our knowledge, this is the first RCT demonstrating the impact of THMP after LT. The magnitude of effect on LT outcomes, hospital readmissions, and QOL suggests that the adoption of telemedicine has great potential for other major operations.

ABSTRACT

Obesity has become an epidemic in the United States over the past decade, and recent studies have shown this trend in the liver transplantation (LT) population. These patients may be candidates for laparoscopic sleeve gastrectomy (LSG) to promote significant and sustained weight loss to prevent recurrence of nonalcoholic steatohepatitis. However, safety remains a concern, and efficacy in this setting is uncertain. A single-institution database from 2014 to 2018 was queried for patients undergoing LSG following LT. The selection criteria for surgery were consistent with National Institutes of Health guidelines, and patients were at least 6 months after LT. A total of 15 patients (median age, 59.0 years; Caucasian, 86.7%; and female, 60%) underwent LSG following LT. Median time from LT to LSG was 2.2 years with a median follow-up period of 2.6 years. The median hospital length of stay (LOS) was 2 days after LSG. Mortality and rate of liver allograft rejection was 0, and there was 1 postoperative complication (a surgical site infection). Following LSG, body mass index (BMI) decreased from 42.7 to 35.9 kg/m2 (P < 0.01), and in 12 patients with at least 1 year of follow-up, the total body weight loss was 20.6%. Following LSG in patients with diabetes, the median daily insulin requirements decreased from 98 (49-118) to 0 (0-29) units/day (P = 0.02), and 60% discontinued insulin. Post-LT patients had a similar decrease in BMI and reduction in comorbidities at 1 year compared with a matched non-LT patient cohort. In the largest patient series to date, we show that LSG following LT is safe, effective, and does not increase the incidence of liver allograft rejection. Larger longer-term studies are needed to confirm underlying metabolic changes following LSG.

ABSTRACT

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) remains a formidable operation associated with considerable morbidity. It is unclear how often these patients require reoperation for postoperative complications and if the need for reoperations leads to worse long-term outcomes. METHODS: The Peritoneal Surface Malignancy Database at a single center was retrospectively queried. Out of 149 entries, 141 HIPECs performed between 2012 and 2018 met inclusion criteria. Patients were categorized based on early reoperation (<60 d after HIPEC), and demographic and tumor factors were compared using univariate analyses. Recurrence was calculated for patients with complete cytoreduction and overall survival analyzed using the Kaplan-Meier method. RESULTS: There were 15 reoperations after 141 HIPECs (10.6%). Median duration between HIPEC and reoperation was 18 d. Indications for reoperation included intra-abdominal infection (n = 5), bowel obstruction (n = 4), wound infection (n = 3), bleeding (n = 2), and evisceration (n = 1). There were no identified patient- or tumor-related risk factors for reoperation. Reoperations were associated with longer hospital length of stay (19 versus 9 d, P = 0.005) and 30-d readmissions (46.7% versus 12.8%, P = 0.003). There was no significant difference in 3-year recurrence-free survival, but there was a significant association between reoperation and 3-year overall survival (38.0% versus 71.9%, P = 0.03). CONCLUSIONS: Complications requiring reoperation after HIPEC lead to increased short-term morbidity, longer hospital length of stay, and most importantly, reduced overall survival. Further studies investigating interventions to decrease complications and reduce reoperation rates are needed to improve outcomes after HIPEC.

ABSTRACT

BACKGROUND: Differences in clinical staging and survival among pancreatic head, body, and tail cancers are not well defined. We aim to identify the prognostic relevance of primary tumor location in patients undergoing treatment for pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS: The National Cancer Database was used to identify patients with PDAC from 1998 to 2011 (n = 175,556). Patients were categorized by primary tumor site into head (67.5%, n = 118,343), body (15.5%, n = 27,218), and tail (17.0%, n = 29,885) groups. Univariate and Cox regression analyses were used to determine covariates associated with overall survival (OS). RESULTS: Patients with head PDAC presented with earlier stage disease (39.2% Stage I/II versus 19.7% versus 16.0%, P < 0.001) and underwent resection more often (27.9% versus 10.7% versus 17.0%, P < 0.001) than those with body or tail tumors. Of surgically resected PDAC, those localized to the head had advanced pathologic stage (84.8% stage II/III versus 66.6% versus 65.6%, P < 0.001), higher nodal positivity (64.9% versus 45.8% versus 45%, P < 0.001), and worse tumor grade (35.9% poorly differentiated versus 29.5% versus 27.8%, P < 0.001). Despite increased utilization of adjuvant therapies (54.4% versus 45.6% versus 42.0%, P < 0.001), patients with head PDAC had inferior OS compared with those with body and tail tumors (P < 0.001). CONCLUSIONS: When examining patients with PDAC undergoing resection, tumor localization to the head is associated with improved resectability because they present earlier. Of resected PDACs, however, those localized to the head have worse OS compared with body and tail tumors. This discrepancy may represent a combination of lead time and selection biases and biologic differences between tumor sites.

ABSTRACT

The approach to screening patients at high risk for breast cancer has thus far been challenging to standardize, given limited high-level evidence in this population. The approach has evolved given the development of more effective screening modalities, including digital breast mammography, magnetic resonance imaging, and other emerging technologies. This review will discuss identification of high-risk patients, approaches to genetic counseling and testing, and evidence behind screening modalities and algorithms in this special population.

ABSTRACT

BACKGROUND: The purpose of the study was to characterize the prevalence and impact of perioperative blood use for patients undergoing hepatic lobectomy at academic medical centers. METHODS: The University HealthSystem Consortium (UHC) database was queried for hepatic lobectomies performed between 2011 and 2014 (n = 6476). Patients were grouped according to transfusion requirements into high (>5 units, 7%), medium (2-5 units, 6%), low (1 unit, 8%), and none (0 units, 79%) during hospital stay for comparison of outcomes. RESULTS: Over 20% of patients undergoing hepatic lobectomy received blood perioperatively, of which 35% required more than 5 units. Patients with high transfusion requirements had increased severity of illness (p < 0.01). High transfusion requirements correlated with increased readmission rates (23.4% vs. 19.2% vs. 16.6% vs. 13.5%), total direct costs ($31,982 vs. $20,859 vs. $19,457 vs. $16,934), length of stay (9 days vs. 8 vs. 7 vs. 6), and in-hospital mortality (10.8% vs. 2.0% vs. 0.9% vs. 2.0%) compared to medium, low, and no transfusion amounts (all p < 0.01). Neither center nor surgeon volume were associated with transfusion use. CONCLUSION: High transfusion requirements after hepatic lobectomy in the United States are associated with worse perioperative quality measures, but may not be influenced by center or surgeon volume.

ABSTRACT

BACKGROUND: As part of ongoing perioperative surgical home implantation process, we applied a previously published algorithm for creation of a maximum surgical blood order schedule (MSBOS) to our operating rooms. We hypothesized that using the MSBOS we could show a reduction in unnecessary preoperative blood testing and associated costs. STUDY DESIGN AND METHODS: Data regarding all surgical cases done at UC Irvine Health's operating rooms from January 1, 2011, to January 1, 2014 were extracted from the anesthesia information management systems (AIMS). After the data were organized into surgical specialties and operative sites, blood order recommendations were generated based on five specific case characteristics of the group. Next, we assessed current ordering practices in comparison to actual blood utilization to identify potential areas of wastage and performed a cost analysis comparing the annual hospital costs from preoperative blood orders if the blood order schedule were to be followed to historical practices. RESULTS: Of the 19,138 patients who were categorized by the MSBOS as needing no blood sample, 2694 (14.0%) had a type and screen (T/S) ordered and 1116 (5.8%) had a type and crossmatch ordered. Of the 6073 procedures where MSBOS recommended only a T/S, 2355 (38.8%) had blood crossmatched. The cost analysis demonstrated an annual reduction in actual hospital costs of $57,335 with the MSBOS compared to historical blood ordering practices. CONCLUSION: We showed that the algorithm for development of a multispecialty blood order schedule is transferable and yielded reductions in preoperative blood product screening at our institution.
