ABSTRACT

Introduction: Pancreatic cancer (PC) surgery has been associated with improved outcomes and value when performed at high-volume centers (HVC; ≥20 surgeries annually) compared to low-volume centers (LVC). Some have used these differences to suggest that regionalization of PC surgery would optimize patient outcomes and expenditures. Methods: A Markov model was created to evaluate 30-day mortality, 30-day complications, and 30-day costs. The differences in these outcome measures between the current and future states were measured to assess the population-level benefits of regionalization. A sensitivity analysis was performed to evaluate the impact of variations of input variables in the model. Results: Among 5958 new cases of pancreatic cancer in California in 2021, a total of 2443 cases (41 %) would be resectable; among patients with resectable PC, a total of 977 (40 %) patients would undergo surgery. In aggregate, HVC and LVC 30-day postoperative complications occurred in 364 patients, 30-day mortality in 35 patients, and healthcare costs expended managing complications were $6,120,660. In the predictive model of complete regionalization to only HVC in California, an estimated 29 fewer complications, 17 fewer deaths, and a cost savings of $487,635 per year would occur. Conclusions and relevance: Pancreatic cancer (PC) surgery has been associated with improved outcomes and value when performed at high-volume centers (HVC; ≥20 surgeries annually) compared to low-volume centers (LVC). Complete regionalization of pancreatic cancer surgery predicted benefits in mortality, complications and cost, though implementing this strategy at a population-level may require investment of resources and redesigning care delivery models.

ABSTRACT

BACKGROUND AND OBJECTIVES: Curative intent therapy is the standard of care for early-stage hepatocellular carcinoma (HCC). However, these therapies are under-utilized, with several treatment and survival disparities. We sought to demonstrate whether the type of facility and distance from treatment center (with transplant capabilities) contributed to disparities in curative-intent treatment and survival for early-stage HCC in California. METHODS: We performed a retrospective analysis of the California Cancer Registry for patients diagnosed with stage I or II primary HCC between 2005 and 2017. Primary and secondary outcomes were receipt of treatment and overall survival, respectively. Multivariable logistic regression and Multivariable Cox proportional hazards regression were used to evaluate associations. RESULTS: Of 19 059 patients with early-stage HCC, only 36% (6778) received curative-intent treatment. Compared to Non-Hispanic White patients, Hispanic patients were less likely, and Asian/Pacific Islander patients were more likely to receive curative-intent treatment. Our results showed that rural residence, public insurance, lower neighborhood SES, and care at non-National Cancer Institute-designated cancer center were associated with not receiving treatment and decreased survival. CONCLUSIONS: Although multiple factors influence receipt of treatment for early-HCC, our findings suggest that early intervention programs should target travel barriers and access to specialist care to help improve oncologic outcomes.

ABSTRACT

BACKGROUND: The Lancet Commission on Global Surgery (LCoGS) recommended an annual surgical rate at which low- and middle-income countries (LMICs) could achieve most of the population-wide benefits of surgery. However, condition-specific guidelines were not proposed. To inform rates of surgery for cancer, we sought to assess the current met and unmet need for oncologic surgery in Ghana. METHODS: Data on all operations performed in Ghana over a one-year period (2014-15) were obtained from representative samples of 48/124 first-level and 12/16 referral hospitals and scaled-up for nationwide estimates. Procedures for cancer were identified by indication. Using modified LCoGS methodology with disease prevalence, Ghana's annual rate of cancer surgery was compared to that of New Zealand to quantify current unmet needs. RESULTS: 232,776 surgical procedures were performed in Ghana; 2,562 procedures (95%UI 1878-3255) were for cancer. Of these, 964 (37%) were surgical biopsies. The annual rate of procedures treating cancer was 2115 surgeries/100,000 cancer cases, or 21% of the New Zealand benchmark. Cervical, breast, and prostate cancer were found to meet 2.1%, 17.2%, and 32.1% of their respective surgical need. CONCLUSIONS: There is a large unmet need for cancer surgery in Ghana. Cancer surgery constitutes under 2% of the total surgeries performed in Ghana, an important proportion of which are used for biopsies. Therapeutic operative rate is deficient across most cancer types, and may lag behind improvements in screening efforts. As cancer prevalence and diagnosis increase in LMICs, cancer-specific surgical capacity must be increased to meet these evolving needs.

ABSTRACT

Systemic chemotherapy improves the survival of patients who undergo pancreatectomy, but whether chemotherapy should be delivered before or after surgery remains debated. At The University of Texas MD Anderson Cancer Center, localized pancreatic ductal adenocarcinoma (PDAC) has been preferentially treated with preoperative therapy-a practice supported by a robust history of institutional and national trials. In the following review, we discuss the historical use of perioperative therapy, our experience with it at MD Anderson Cancer Center and internationally, and the future of treatment and trials for PDAC.

ABSTRACT

Importance: Surgeons are increasingly interested in using mobile and online applications with wound photography to monitor patients after surgery. Early work using remote care to diagnose surgical site infections (SSIs) demonstrated improved diagnostic accuracy using wound photographs to augment patients' electronic reports of symptoms, but it is unclear whether these findings are reproducible in real-world practice. Objective: To determine how wound photography affects surgeons' abilities to diagnose SSIs in a pragmatic setting. Design, Setting, and Participants: This prospective study compared surgeons' paired assessments of postabdominal surgery case vignettes with vs without wound photography for detection of SSIs. Data for case vignettes were collected prospectively from May 1, 2007, to January 31, 2009, at Erasmus University Medical Center, Rotterdam, the Netherlands, and from July 1, 2015, to February 29, 2016, at Vanderbilt University Medical Center, Nashville, Tennessee. The surgeons were members of the American Medical Association whose self-designated specialty is general, abdominal, colorectal, oncologic, or vascular surgery and who completed internet-based assessments from May 21 to June 10, 2016. Intervention: Surgeons reviewed online clinical vignettes with or without wound photography. Main Outcomes and Measures: Surgeons' diagnostic accuracy, sensitivity, specificity, confidence, and proposed management with respect to SSIs. Results: A total of 523 surgeons (113 women and 410 men; mean [SD] age, 53 [10] years) completed a mean of 2.9 clinical vignettes. For the diagnosis of SSIs, the addition of wound photography did not change accuracy (863 of 1512 [57.1%] without and 878 of 1512 [58.1%] with photographs). Photographs decreased sensitivity (from 0.58 to 0.50) but increased specificity (from 0.56 to 0.63). In 415 of 1512 cases (27.4%), the addition of wound photography changed the surgeons' assessment (215 of 1512 [14.2%] changed from incorrect to correct and 200 of 1512 [13.2%] changed from correct to incorrect). Surgeons reported greater confidence when vignettes included a wound photograph compared with vignettes without a wound photograph, regardless of whether they correctly identified an SSI (median, 8 [interquartile range, 6-9] vs median, 8 [interquartile range, 7-9]; P < .001) but they were more likely to undertriage patients when vignettes included a wound photograph, regardless of whether they correctly identified an SSI. Conclusions and Relevance: In a practical simulation, wound photography increased specificity and surgeon confidence, but worsened sensitivity for detection of SSIs. Remote evaluation of patient-generated wound photographs may not accurately reflect the clinical state of surgical incisions. Effective widespread implementation of remote postoperative assessment with photography may require additional development of tools, participant training, and mechanisms to verify image quality.

ABSTRACT

PURPOSE: The burden of breast cancer continues to increase in low- and middle-income countries (LMICs), where women present with more advanced disease and have worse outcomes compared with women from high-income countries. In the absence of breast cancer screening in LMICs, patients must rely on self-detection for early breast cancer detection, followed by a prompt clinical diagnostic work-up. Little is known about the influence of religious beliefs on women's perceptions and practices of breast health. METHODS: A cross-sectional survey was administered to female members of Islamic and Christian organizations in Ghana. Participants were asked about their personal experience with breast concerns, knowledge of breast cancer, performance of breast self-examination, and experience with clinical breast exam. RESULTS: The survey was administered to 432 Muslim and 339 Christian women. Fewer Muslim women knew someone with breast cancer (31% v 66%; P < .001) or had previously identified a concerning mass in their breast (16% v 65%; P < .001). Both groups believed that new breast masses should be evaluated at clinic (adjusted odds ratio [AOR], 1.08; 95% CI, 0.58 to 2.01), but Muslim women were less likely to know that breast cancer can be effectively treated (AOR, 0.34; 95% CI, 0.23 to 0.50). Muslim women were less likely to have performed breast self-examination (AOR, 0.51; 95% CI, 0.29 to 0.88) or to have undergone clinical breast exam (AOR, 0.48; 95% CI, 0.27 to 0.84). CONCLUSION: Muslim women were found to be less likely to participate in breast health activities compared with Christian women, which highlights the need to consider how religious customs within subpopulations might impact a woman's engagement in breast health activities. As breast awareness initiatives are scaled up in Ghana and other LMICs, it is essential to consider the unique perception and participation deficits of specific groups.

ABSTRACT

BACKGROUND AND OBJECTIVES: Outcome data after surgery for cancer in Sub-Saharan Africa are insufficient. We aimed to describe the presentation and outcomes of patients with solid cancers managed at a tertiary hospital in Ghana. METHODS: Records of cancer patients admitted to Komfo Anokye Teaching Hospital general surgery wards from 2013 to 2016 were reviewed for data on presentation, staging, management, and mortality. Patients discharged alive were followed-up by biannual telephone calls to establish their postdischarge status. Survival analysis was performed for patients with pathologic or radiologic confirmation of cancer and adequate staging. RESULTS: A total of 343 patients were included. Of these, 76% were female. The most common diagnoses were breast 136 (40%), foregut 70 (20%), and colorectal 63 (18%) cancers. Cancer diagnosis was confirmed by pathology or radiology in 281 (82%) patients, but only 112 (40%) had adequate staging. Seventy-four (66%) patients were stage IV. Two-year overall survival for all 343 patients was 22% to 69%, depending on cancer site. Among those with adequate staging who were alive after postoperative 90 days, 3-year survival was similar for curative compared with palliative operations (P = 0.64). CONCLUSIONS: Improved capacity for both therapeutic and palliative cancer care is needed to achieve better outcomes by more appropriate allocation of surgery with respect to the goal of treatment.

ABSTRACT

Importance: Clinician miscommunication contributes to an estimated 250 000 deaths in US hospitals per year. Efforts to standardize handoff communication may reduce errors and improve patient safety. Objective: To determine the effect of a standardized handoff curriculum, UW-IPASS, on interclinician communication and patient outcomes. Design, Setting, and Participants: This cluster randomized stepped-wedge randomized clinical trial was conducted from October 2015 to May 2016 at 8 medical and surgical intensive care units at 2 hospital systems within an academic tertiary referral center. Participants included residents, fellows, advance-practice clinicians, and attending physicians (n = 106 clinicians, with 1488 handoff events over 8 months) and data were collected from daily text message-based surveys and patient medical records. Exposures: The UW-IPASS standardized handoff curriculum. Main Outcomes and Measures: The primary aim was to assess the effect of the UW-IPASS handoff curriculum on perceived adequacy of interclinician communication. Patient days of mechanical ventilation, intensive care unit length of stay, reintubations within 24 hours, and order workflow patterns were also analyzed. Mixed-effects logistic regression was used to compute odds ratios and confidence intervals with adjustment for location, time period, and clinician. Results: A total of 63 residents and advance practice clinicians, 13 fellows, and 30 attending physicians participated in the study. During the control period, clinicians reported being unprepared for their shift because of a poor-quality handoff in 35 of 343 handoffs (10.2%), while UW-IPASS-period residents reported being unprepared in 53 of 740 handoffs (7.2%) (odds ratio, 0.19; 95% CI, 0.03-0.74; P = .03). Compared with the control phase, the perceived duration of handoffs among clinicians using UW-IPASS was unchanged (+5.5 minutes; 95% CI, 0.34-9.39; P = .30). Early morning order entry decreased from 106 per 100 patient-days in the control phase to 78 per 100 patient-days in the intervention period (-28 orders; 95% CI, -55 to -4; P = .04). Overall, UW-IPASS was not associated with any changes in intensive care unit length of stay, duration of mechanical ventilation, or the number of reintubations. Conclusions and Relevance: The UW-IPASS standardized handoff curriculum was perceived to improve intensive care provider preparedness and workflow. IPASS-based curricula represent an important step forward in communication standardization efforts and may help reduce communication errors and omissions.

ABSTRACT

PURPOSE: Urgent appendectomy has long been the standard of care for acute appendicitis. Six randomized trials have demonstrated that antibiotics can safely treat appendicitis, but approximately 1 in 4 of these patients eventually requires appendectomy. Overall treatment success may be limited by complex disease including perforation. Patients׳ success on antibiotic therapy may depend on preoperative identification of complex disease on imaging. However, the effectiveness of computed tomography (CT) in differentiating complex disease including perforated from nonperforated appendicitis remains to be determined. The purpose of this study was to assess the preoperative diagnostic accuracy of CT in determining appendiceal perforation in patients operated for acute appendicitis. METHODS: We performed a retrospective review of pathology and radiology reports from consecutive patients who presented to the emergency department with suspicion for acute appendicitis between January 2012 and May 2015. CT scans were re-reviewed by abdominal imaging fellowship-trained radiologists using standardized criteria, and the radiologists were blinded to pathology and surgical findings. Radiologists specifically noted presence or absence of periappendiceal gas, abscess, appendicolith, fat stranding, and bowel wall thickening. The overall radiologic impression as well as these specific imaging findings was compared to results of pathology and operative reports. Pathology reports were considered the standard for diagnostic accuracy. RESULTS: Eighty-nine patients (65% male, average age of 34 years) presenting with right lower quadrant pain underwent CT imaging and prompt appendectomy. Final pathology reported perforation in 48% (n = 43) of cases. Radiologic diagnosis of perforation was reported in 9% (n = 8), correctly identifying perforation in 37.5% (n = 3), and incorrectly reporting perforation in 62.5% of nonperforated cases per pathology. Radiology missed 93% (n = 40) of perforations postoperatively diagnosed by pathology. There was no secondary finding (fat stranding, diameter >13mm, abscess, cecal wall thickening, periappendiceal gas, simple fluid collection, appendicolith, and phlegmon) with a clinically reliable sensitivity or specificity to predict perforated appendicitis. Surgeon׳s report of perforation was consistent with the pathology report of perforation in only 28% of cases. CONCLUSIONS: The usefulness of a CT for determining perforation in acute appendicitis is limited, and methods to improve precision in identifying patients with complicated appendicitis should be explored as this may help for improving risk prediction for failure of treatment with antibiotic therapy and help guide patients and providers in shared decision-making for treatment options.

ABSTRACT

BACKGROUND: Cigarette smoking increases the risk of postoperative complications nearly 2-fold. Preoperative smoking cessation programs may reduce complications as well as overall postoperative costs. We aim to create an economic evaluation framework to estimate the potential value of preoperative smoking cessation programs for patients undergoing elective colorectal surgery. METHODS: A decision-analytic model from the payer perspective was developed to integrate the costs and incidence of 90-day postoperative complications and readmissions for a cohort of patients undergoing elective colorectal surgery after a smoking cessation program versus usual care. Complication, readmission, and cost data were derived from a cohort of 534 current smokers and recent quitters undergoing elective colorectal resections in Washington State's Surgical Care and Outcomes Assessment Program linked to Washington State's Comprehensive Hospital Abstract Reporting System. Smoking cessation program efficacy was obtained from the literature. Sensitivity analyses were performed to account for uncertainty. RESULTS: For a cohort of patients, the base case estimates imply that the total direct medical costs for patients who underwent a preoperative smoking cessation program were on average $304 (95% CI: $40-$571) lower per patient than those under usual care during the first 90 days after surgery. The model was most sensitive to the odds of recent quitters developing complications or requiring readmission, and smoking program efficacy. CONCLUSIONS: A preoperative smoking cessation program is predicted to be cost-saving over the global postoperative period if the cost of the intervention is below $304 per patient. This framework allows the value of smoking cessation programs of variable cost and effectiveness to be determined.

ABSTRACT

BACKGROUND: Postoperative surgical site infections (SSI) are common and costly. Most occur post discharge, and can result in potentially preventable readmission or unnecessary urgent evaluation. Mobile health approaches incorporating patient-generated wound photos are being implemented in an attempt to optimize triage and management. We assessed how adding wound photos to existing data sources modifies provider decision making. STUDY DESIGN: We used a web-based simulation survey using a convenience sample of providers with expertise in surgical infections. Participants viewed a range of scenarios, including surgical history, physical exam, and description of wound appearance. All participants reported SSI diagnosis, diagnostic confidence, and management recommendations (main outcomes) first without, and then with, accompanying wound photos. At each step, participants ranked the most important features contributing to their decision. RESULTS: Eighty-three participants completed a median of 5 scenarios (interquartile range 4 to 7). Most participants were physicians in academic surgical specialties (n = 70 [84%]). The addition of photos improved overall diagnostic accuracy from 67% to 76% (p < 0.001), and increased specificity from 77% to 92% (p < 0.001), but did not significantly increase sensitivity (55% to 65%; p = 0.16). Photos increased mean confidence in diagnosis from 5.9 of 10 to 7.4 of 10 (p < 0.001). Overtreatment recommendations decreased from 48% to 16% (p < 0.001), and undertreatment did not change (28% to 23%; p = 0.20) with the addition of photos. CONCLUSIONS: The addition of wound photos to existing data as available via chart review and telephone consultation with patients significantly improved diagnostic accuracy and confidence, and prevented proposed overtreatment in scenarios without SSI. Post-discharge mobile health technologies have the potential to facilitate patient-centered care, decrease costs, and improve clinical outcomes.
