The use of broad tool repertoires to increase dietary flexibility through extractive foraging behaviors is shared by humans and their closest living relatives (chimpanzees, Pan troglodytes). However, comparisons between tool use in ancient human ancestors (hominins) and chimpanzees are limited by differences in their toolkits. One feature shared by primate and hominin toolkits is rock selection based on physical properties of the stones and the targets of foraging behaviors. Here, we document the selectivity patterns of stone tools used by wild chimpanzees to crack nuts at Bossou, Guinea, through controlled experiments that introduce rocks unknown to this population. Experiments incorporate specific rock types because previous studies document hominin selection of these lithologies at Kanjera South 2 Ma. We investigate decisions made by chimpanzees when selecting stones that vary in their mechanical properties-features not directly visible to the individual. Results indicate that the selection of anvils and hammers is linked to task-specific mechanical properties. Chimpanzees select harder stones for hammers and softer stones for anvils, indicating an understanding of specific properties for distinct functions. Selectivity of rock types suggests that chimpanzees assess the appropriate materials for functions by discriminating these 'invisible' properties. Adults identify mechanical properties through individual learning, and juveniles often reused the tools selected by adults. Selection of specific rock types may be transmitted through the reuse of combinations of rocks. These patterns of stone selection parallel what is documented for Oldowan hominins. The processes identified in this experiment provide insights into the discrete nature of hominin rock selection patterns in Plio-Pleistocene stone artifact production., (Copyright © 2024 The Authors.

Purpose: The aim of this study is to uncover potential areas for cost savings in uterine artery embolization (UAE) using time-driven activity-based costing, the most accurate costing methodology for direct health care system costs., Methods: One hundred twenty-three patients who underwent outpatient UAE for fibroids or adenomyosis between January 2020 and December 2022 were retrospectively reviewed. Utilization times were captured from electronic health record time stamps and staff interviews using validated techniques. Capacity cost rates were estimated using institutional data and manufacturer proxy prices. Costs were calculated using time-driven activity-based costing for personnel, equipment, and consumables. Differences in time utilization and costs between procedures by an interventional radiology attending physician only versus an interventional radiology attending physician and trainee were additionally performed., Results: The mean total cost of UAE was $4,267 ± $1,770, the greatest contributor being consumables (51%; $2,162 ± $811), followed by personnel (33%; $1,388 ± $340) and equipment (7%; $309 ± $96). Embolic agents accounted for the greatest proportion of consumable costs, accounting for 51% ($1,273 ± $789), followed by vascular devices (15%; $630 ± $143). The cost of embolic agents was highly variable, driven mainly by the number of vials (range 1-19) of tris-acryl gelatin particles used. Interventional radiology attending physician only cases had significantly lower personnel costs ($1,091 versus $1,425, P = .007) and equipment costs ($268 versus $317, P = .007) compared with interventional radiology attending physician and trainee cases, although there was no significant difference in mean overall costs ($3,640 versus $4,386; P = .061)., Conclusions: Consumables accounted for the majority of total cost of UAE, driven by the cost of embolic agents and vascular devices., (Copyright © 2024 American College of Radiology.

The US fee-for-service payment system under-reimburses clinics offering access to comprehensive treatments for opioid use disorder (OUD). The funding shortfall limits a clinic's ability to expand and improve access, especially for socially marginalized patients with OUD. New payment models, however, should reflect the high variation in cost for using a clinic's clinical and voluntary psychosocial and recovery support services. The authors applied time-driven activity-based costing, a patient-level, micro-costing approach, to estimate the cost at an outpatient clinic that delivers medication for opiate used disorder (MOUD) and voluntary psychosocial and recovery support services. Much of the cost variation could be explained by classifying patients into three archetypes: (1) light touch (1-3 visits): no significant co-occurring psychiatric illness, stable housing, and easy to connect for ongoing OUD treatment in a traditional outpatient setting; (2) standard (average of 8 visits): initially requires an integrated team-based care model but soon stabilizes for transition to community-based outpatient care; (3) quad morbidity (> 20 visits): multiple co-occurring substance use disorders, unhoused, co-occurring medical and psychiatric complexity, and limited social supports. With the cost of the initial visit set at an indexed value of 100, an average light touch patient had a cost of 352, a standard patient was 718, and a quad morbidity patient was 1701. The cost structure revealed by this analysis provides the foundation for alternative payment models that would enable new MOUD clinics, staffed with multi-disciplinary care teams, and located for convenient access by high-risk patients, to be established and sustained., (© 2023.

Objective: Measuring the cost of performing breast imaging is difficult in healthcare systems. The purpose of our study was to evaluate this cost using time-driven activity-based costing (TDABC) and to evaluate cost drivers for different exams., Methods: An IRB-approved, single-center prospective study was performed on 80 female patients presenting for breast screening, diagnostic or biopsy exams from July 2020 to April 2021. Using TDABC, data were collected for each exam type. Included were full-field digital mammography (FFDM), digital breast tomosynthesis (DBT), contrast-enhanced mammography (CEM), US and MRI exams, and stereotactic, US-guided and MRI-guided biopsies. For each exam type, mean cost and relative contributions of equipment, personnel and supplies were calculated., Results: Screening MRI, CEM, US, DBT, and FFDM costs were $249, $120, $83, $28, and $30. Personnel was the major contributor to cost (60.0%-87.0%) for all screening exams except MRI where equipment was the major contributor (62.2%). Diagnostic MRI, CEM, US, and FFDM costs were $241, $123, $70, and $43. Personnel was the major contributor to cost (60.5%-88.6%) for all diagnostic exams except MRI where equipment was the major contributor (61.8%). Costs of MRI-guided, stereotactic and US-guided biopsy were $1611, $826, and $356. Supplies contributed 40.5%-49.8% and personnel contributed 30.7%-55.6% to the total cost of biopsies., Conclusion: TDABC provides assessment of actual costs of performing breast imaging. Costs and contributors varied across screening, diagnostic and biopsy exams and modalities. Practices may consider this methodology in understanding costs and making changes directed at cost savings., (© Society of Breast Imaging 2023. All rights reserved.

Background The effects of regional histopathologic changes on prostate MRI scans have not been accurately quantified in men with an elevated prostate-specific antigen (PSA) level and no previous biopsy. Purpose To assess how Gleason grade, maximum cancer core length (MCCL), inflammation, prostatic intraepithelial neoplasia (PIN), or atypical small acinar proliferation within a Barzell zone affects the odds of MRI visibility. Materials and Methods In this secondary analysis of the Prostate MRI Imaging Study (PROMIS; May 2012 to November 2015), consecutive participants who underwent multiparametric MRI followed by a combined biopsy, including 5-mm transperineal mapping (TPM), were evaluated. TPM pathologic findings were reported at the whole-prostate level and for each of 20 Barzell zones per prostate. An expert panel blinded to the pathologic findings reviewed MRI scans and declared which Barzell areas spanned Likert score 3-5 lesions. The relationship of Gleason grade and MCCL to zonal MRI outcome (visible vs nonvisible) was assessed using generalized linear mixed-effects models with random intercepts for individual participants. Inflammation, PIN, and atypical small acinar proliferation were similarly assessed in men who had negative TPM results. Results Overall, 161 men (median age, 62 years [IQR, 11 years]) were evaluated and 3179 Barzell zones were assigned MRI status. Compared with benign areas, the odds of MRI visibility were higher when a zone contained cancer with a Gleason score of 3+4 (odds ratio [OR], 3.1; 95% CI: 1.9, 4.9; P < .001) or Gleason score greater than or equal to 4+3 (OR, 8.7; 95% CI: 4.5, 17.0; P < .001). MCCL also determined visibility (OR, 1.24 per millimeter increase; 95% CI: 1.15, 1.33; P < .001), but odds were lower with each prostate volume doubling (OR, 0.7; 95% CI: 0.5, 0.9). In men who were TPM-negative, the presence of PIN increased the odds of zonal visibility (OR, 3.7; 95% CI: 1.5, 9.1; P = .004). Conclusion An incremental relationship between cancer burden and prostate MRI visibility was observed. Prostatic intraepithelial neoplasia contributed to false-positive MRI findings.

Background: The COVID-19 pandemic raised awareness of the need to better understand where and how patient-level costs are incurred in health care organizations, as health managers and other decision-makers need to plan and quickly adapt to the increasing demand for health care services to meet patients' care needs. Time-driven activity-based costing offers a better understanding of the drivers of cost throughout the care pathway, providing information that can guide decisions on process improvement and resource optimization. This study aims to estimate COVID-19 patient-level hospital costs and to evaluate cost variability considering the in-hospital care pathways of COVID-19 management and the patient clinical classification., Methods: This is a prospective cohort study that applied time-driven activity-based costing (TDABC) in a Brazilian reference center for COVID-19. Patients hospitalized during the first wave of the disease were selected for their data to be analyzed to estimate in-hospital costs. The cost information was calculated at the patient level and stratified by hospital care pathway and Ordinal Scale for Clinical Improvement (OSCI) category. Multivariable analyses were applied to identify predictors of cost variability in the care pathways that were evaluated., Results: A total of 208 patients were included in the study. Patients followed five different care pathways, of which Emergency + Ward was the most followed (n = 118, 57%). Pathways which included the intensive care unit presented a statistically significant influence on costs per patient (p <  0.001) when compared to Emergency + Ward. The median cost per patient was I$2879 (IQR 1215; 8140) and mean cost per patient was I$6818 (SD 9043). The most expensive care pathway was the ICU only, registering a median cost per patient of I$13,519 (IQR 5637; 23,373) and mean cost per patient of I$17,709 (SD 16,020). All care pathways that included the ICU unit registered a higher cost per patient., Conclusions: This is one of the first microcosting study for COVID-19 that applied the TDABC methodology and demonstrated how patient-level costs vary as a function of the care pathways followed by patients. These findings can be used to develop value reimbursement strategies that will inform sustainable health policies in middle-income countries such as Brazil., (© 2023. The Author(s).)

Background: Primary care physicians are overburdened with growing complexities and increasing expectations for primary care visits. To meet expectations, primary care physicians must multitask during visits and spend extra hours in the office for charting, billing, and documentation. This impacts the physician's quality of life and may affect the quality of patient care. Many of the administrative tasks performed by physicians could, alternatively, be performed by nonphysician staff, leading to the adoption of team-based collaborative models., Methods: Mayo Clinic Health System piloted a team-based collaborative model in a small physician practice in Osseo, Wisconsin, where which staff could be trained quickly and efficiently. The model used medical assistants/licensed practical nurses (MA/LPN) to partner with primary care physicians during a patient visit. The LPN/MA, under physician supervision, ordered and monitored pending orders/labs, coordinated patient care, provided after-visit educational needs, and communicated other urgent messages to team members., Results: After 6 months, a comparison of pre- and posttrial data showed improved staff and patient satisfaction, decreased physician administrative work, and no cost-effectiveness improvement. Screening of medical conditions in the elderly improved, but no change was noted with chronic disease metrics., Conclusions: Data showed improved staff and patient satisfaction, decreased physician clerical burden, increased appointment slots, mixed clinical outcomes, and did not demonstrate cost-effectiveness. The authors recommend that similar models be conducted in large settings to see if these results are reproducible., (Copyright© Board of Regents of the University of Wisconsin System and The Medical College of Wisconsin, Inc.)

The United States spends more for intensive care units (ICUs) than do other high-income countries. We used time-driven activity-based costing (TDABC) to analyze ICU costs for initiation of veno-venous extracorporeal membrane oxygenation (VV ECMO) for respiratory failure to estimate how much of the higher ICU costs at 1 US site can be attributed to the higher prices paid to ICU personnel, and how much is caused by the US site's use of a higher cost staffing model. We accompanied our TDABC approach with narrative review of the ECMO programs, at Cedars-Sinai (Los Angeles), Hôpital Pitié-Salpêtrière (Paris), and The Alfred Hospital (Melbourne) from 2017 to 2019. Our primary outcome was daily ECMO cost, and we hypothesized that cost differences among the hospitals could be explained by the efficiencies and skill mix of involved clinicians and prices paid for personnel, equipment, and consumables. Our results are presented relative to Los Angeles' total personnel cost per VV ECMO patient day, indexed at 100. Los Angeles' total indexed daily cost of care was 147 (personnel: 100, durables: 5, and disposables: 42). Paris' total cost was 39 (26% of Los Angeles) (personnel: 12, durables: 1, and disposables: 26). Melbourne's total cost was 53 (36% of Los Angeles) (personnel: 32, durables: 2, and disposables: 19) (rounded). The higher personnel prices at Los Angeles explained only 26% of its much higher personnel costs than Paris, and 21% relative to Melbourne. Los Angeles' higher staffing levels accounted for 49% (36%), and its costlier mix of personnel accounted for 12% (10%) of its higher personnel costs relative to Paris (Melbourne). Unadjusted discharge rates for ECMO patients were 46% in Los Angeles (46%), 56% in Paris, and 52% in Melbourne. We found that personnel salaries explained only 30% of the higher personnel costs at 1 Los Angeles hospital. Most of the cost differential was caused by personnel staffing intensity and mix. This study demonstrates how TDABC may be used in ICU administration to quantify the savings that 1 US hospital could achieve by delivering the same quality of care with fewer and less-costly mix of clinicians compared to a French and Australian site. Narrative reviews contextualized how the care models evolved at each site and helped identify potential barriers to change., Competing Interests: Conflicts of Interest: See Disclosures at the end of the article., (Copyright © 2022 International Anesthesia Research Society.)

Aims: To compare the cost of cardiac stereotactic body radioablation therapy (SBRT) versus catheter ablation for treating ventricular tachycardia (VT)., Background: Cardiac SBRT is a novel way of treating refractory VT that may be less costly than catheter ablation, owing to its noninvasive, outpatient nature. However, the true costs of either procedure are not well described, which could help inform a more appropriate reimbursement for cardiac SBRT than simply cross-indexing existing procedural rates., Methods: Process maps were derived for the full patient care cycle of both procedures using time-driven activity-based costing. Step-by-step timestamps were collected prospectively from a 10-patient SBRT cohort and retrospectively from a 59-patient catheter ablation cohort. Individual costs were estimated by multiplying timestamps with capacity cost rates (CCRs) for personnel, space, equipment, consumable, and indirect resources. These were summed into total cost, which for cardiac SBRT was compared with current catheter ablation and single-fraction lung SBRT reimbursements, both potential reference rates for cardiac SBRT., Results: The direct and total procedural costs of cardiac SBRT ($7549 and $10,621) were 49% and 54% less than those of VT ablation ($14,707 and $23,225). These costs were significantly different from current reimbursement for catheter ablation ($22,692) and lung SBRT ($6329). After including hospitalization expenses (≥$15,000), VT ablation costs at least $27,604 more to furnish than cardiac SBRT., Conclusions: Time-driven activity-based costing (TDABC) can be a helpful tool for assessing healthcare costs, including novel treatment approaches. In addition to its clinical benefits, cardiac SBRT may provide significant cost reduction opportunities for treatment of VT., (© 2022 Wiley Periodicals LLC.)

Purpose: Survival in stage I seminoma is almost 100%. Computed tomography (CT) surveillance is an international standard of care, avoiding adjuvant therapy. In this young population, minimizing irradiation is vital. The Trial of Imaging and Surveillance in Seminoma Testis (TRISST) assessed whether magnetic resonance images (MRIs) or a reduced scan schedule could be used without an unacceptable increase in advanced relapses., Methods: A phase III, noninferiority, factorial trial. Eligible participants had undergone orchiectomy for stage I seminoma with no adjuvant therapy planned. Random assignment was to seven CTs (6, 12, 18, 24, 36, 48, and 60 months); seven MRIs (same schedule); three CTs (6, 18, and 36 months); or three MRIs. The primary outcome was 6-year incidence of Royal Marsden Hospital stage ≥ IIC relapse (> 5 cm), aiming to exclude increases ≥ 5.7% (from 5.7% to 11.4%) with MRI ( v CT) or three scans ( v 7); target N = 660, all contributing to both comparisons. Secondary outcomes include relapse ≥ 3 cm, disease-free survival, and overall survival. Intention-to-treat and per-protocol analyses were performed., Results: Six hundred sixty-nine patients enrolled (35 UK centers, 2008-2014); mean tumor size was 2.9 cm, and 358 (54%) were low risk (< 4 cm, no rete testis invasion). With a median follow-up of 72 months, 82 (12%) relapsed. Stage ≥ IIC relapse was rare (10 events). Although statistically noninferior, more events occurred with three scans (nine, 2.8%) versus seven scans (one, 0.3%): 2.5% absolute increase, 90% CI (1.0 to 4.1). Only 4/9 could have potentially been detected earlier with seven scans. Noninferiority of MRI versus CT was also shown; fewer events occurred with MRI (two [0.6%] v eight [2.6%]), 1.9% decrease (-3.5 to -0.3). Per-protocol analyses confirmed noninferiority. Five-year survival was 99%, with no tumor-related deaths., Conclusion: Surveillance is a safe management approach-advanced relapse is rare, salvage treatment successful, and outcomes excellent, regardless of imaging frequency or modality. MRI can be recommended to reduce irradiation; and no adverse impact on long-term outcomes was seen with a reduced schedule.

Billing and insurance-related costs are a significant source of wasteful health care spending in Organization for Economic Cooperation and Development nations, but these administrative burdens vary across national systems. We executed a microlevel accounting of these costs in different national settings at six provider locations in five nations (Australia, Canada, Germany, the Netherlands, and Singapore) that supplements our prior study measuring the costs in the US. We found that billing and insurance-related costs for inpatient bills range from a low of $6 in Canada to a high of $215 in the US for an inpatient surgical bill (purchasing power parity adjusted). We created a taxonomy of billing and insurance-related activities (eligibility, coding, submission, and rework) that was applied to data from the six sites and allows cross-national comparisons. Higher costs in the US and Australia are attributed to high coding costs. Much of the savings achieved in some nations is attributable to assigning tasks to people in lower-skill job categories, although most of the savings are due to more efficient billing and insurance-related processes. Some nations also reduce these costs by offering financial counseling to patients before treatment. Our microlevel approach can identify specific cost drivers and reveal national billing features that reduce coding costs. It illustrates a valuable pathway for future research in understanding and mitigating administrative costs in health care.

Introduction: Studies comparing the cost of in-person and virtual care are lacking. The goal of this study was threefold (1) to compare the cost of telemedicine visits with in-person clinic visits after common shoulder surgeries, (2) to measure the safety, and (3) to evaluate patient experience with telemedicine visits., Methods: The In-Person Visit cohort (N = 25) and the telemedicine cohort (Virtual Visit cohort, N = 24) were selected from patients undergoing routine follow-up of common shoulder procedures. Time-driven activity-based costing was used to determine costs associated with each episode of care. Patient complications, satisfaction, convenience, and technical difficulties associated with telehealth were recorded., Results: The average Virtual Visit was 54.1% less costly and 87.8% shorter than the In-Person Visit ($49 versus $107 per patient, 8.6 versus 70.1 minutes per patient, P < 0.01, respectively). One complication was missed in the Virtual Visit cohort, later captured by an in-person visit. All patients in the Virtual Visit cohort reported that the virtual visit was safe and convenient and showed high levels of satisfaction., Discussion: Virtual visits for postoperative care of patients undergoing shoulder surgery are associated with decreased costs and high ratings of convenience and satisfaction. Postoperative complications may be more challenging to diagnose virtually., (Copyright © 2022 The Authors.

The culmination of 80+ years of cancer research implicates the aberrant metabolism in tumor cells as a root cause of pathogenesis. Citrate is an essential molecule in intermediary metabolism, and its amplified availability to critical pathways in cancer cells via citrate transporters confers a high rate of cancer cell growth and proliferation. Inhibiting the plasma membrane and mitochondrial citrate transporters - whether individually, in combination, or partnered with complementary metabolic targets - in order to combat cancer may prove to be a consequential chemotherapeutic strategy. This review aims to summarize the use of different classes of citrate transporter inhibitors for anticancer activity, either individually or as part of a cocktail.

Objective: Women's health has demanded more attention from employers as women integrated into the workforce. Traditionally male-dominant fields and occupations require special attention to workplace design, physical standards for entry, employment practices, equipment, and health monitoring. This editorial summarizes the Defense Health Board's (DHB) review of Active Duty Women's Health and its recommendations grounded in a woman's career life-cycle., Methods: The DHB reviewed the Department of Defense and foreign militaries' current women's health services, relevant policies and practices, peer-reviewed scientific literature, and subject matter expert interviews., Results: The DHB's recommendations centered on a comprehensive approach to education, health care access and treatment, professional workforce development, workplace standards and equipment, and accountable outcomes metrics to guide improvement., Conclusions: Employers can learn how to reduce morbidity, leading to a healthier and more productive female workforce., Competing Interests: Conflict of Interest: R.S.K., V.S.L., C.B.G., K.L.M., G.A.A., and M.D.P. are former members of the Defense Health Board.

The U.S. Military Health System spends about $50 billion annually to provide care to 9.6 million active duty service members, retirees, and their families through its TRICARE health plans. TRICARE follows the predominant payment model in the USA-fee-for-service-although the Department of Defense (DoD) and Congress encourage and mandate a move toward alternative payment models-mainly, fee-for-value. For the next TRICARE contracts which will begin in 2023, the DoD asked its health-focused federal advisory committee, the Defense Health Board (DHB), to recommend how best to assess and prioritize leading value-based healthcare initiatives identified from private, public, and employer-based health plans. The November 2020 report, 'Modernization of the TRICARE Benefit', specifies a rubric to evaluate these value-based care initiatives not only in traditional measures of effectiveness but also in terms of the Defense Health Agency's Quadruple Aim with its focus on readiness. The goal of TRICARE's move toward value-based care is to leverage its size and focus on prevention of disease and injury to maintain the readiness of the U.S. Armed Forces in addition to delivering great outcomes and value to the DoD's nearly 10 million beneficiaries. The DHB emphasizes that TRICARE's size and focus on providing quality care at lower cost will incentivize providers to participate in the shift toward value-based care despite the potential challenges in transitioning to this system. This shift also aims to motivate other large government and private payors to accelerate the adoption of value-based care through TRICARE's example., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2021.

Background: Accurate measurement of healthcare costs is required to assess and improve the value of oncology care., Objectives: We aimed to determine the cost of breast cancer care provision across collaborating health care organizations., Methods: We used time-driven activity-based costing (TDABC) to calculate the complete cost of breast cancer care-initial treatment planning, chemotherapy, radiation therapy, surgical resection and reconstruction, and ancillary services (e.g., psychosocial oncology, physical therapy)-across multiple hospital sites. Data were collected between December 2019 and February 2020. TDABC steps involved (1) developing process maps for care delivery pathways; (2) determine capacity cost rates for staff, medical equipment, and hospital space; (3) measure the time required for each process step, both manually through clinic observation and using data from the Real-Time Location System (RTLS); and (4) calculate the total cost of care delivery., Results: Surgical care costs ranged from $1431 for a lumpectomy to $12,129 for a mastectomy with prepectoral implant reconstruction. Radiation therapy was costed at $1224 for initial simulation and patient education, and $200 for each additional treatment. Base costs for chemotherapy delivery were $382 per visit, with additional costs driven by chemotherapy agent(s) administered. Personnel expenses were the greatest contributor to the cost of surgical care, except in mastectomy with implant reconstruction, where device costs equated to up to 60% of the cost of surgery., Conclusion: The cost of complete breast cancer care depended on (1) treatment protocols; (2) patient choice of reconstruction; and (3) the need for ancillary services (e.g., physical therapy). Understanding the actual costs and cost drivers of breast cancer care delivery may better inform resource utilization to lower the cost and improve the quality of care., (© 2021.

Introduction: Integrated quality improvement (QI) and cost reduction strategies can help increase value in cancer care. Time-driven activity-based costing (TDABC) is a bottom-up costing tool that measures resource use over the full care cycle. We applied standard QI and TDABC methods to improve workflow efficiency and reduce costs for MRI-guided prostate brachytherapy., Methods and Materials: We constructed process maps of the baseline prostate brachytherapy workflow from initial consultation through one year after treatment. Process maps reflected resources and time required at each step. TDABC costs were calculated by multiplying each process time by the cost per min of the resource(s) used at that step. We then used plan-do-study-act methodology to identify workflow inefficiencies and implement solutions to reduce resource consumption., Results: The highest cost components at baseline were the operating room (OR) (40%), imaging (8.7%), and consultation (7.6%). Higher-than-expected costs (3%) were incurred during surgery scheduling. After targeted QI initiatives, OR time was reduced from 90 to 70 min, which reduced overall cost by 5%. Personnel task downshifting reduced costs by 10% at consultation and 77% at surgery scheduling. Re-engineering of follow-up protocols reduced costs by 8.4%. Costs under the new workflow decreased by 18.2%., Conclusions: TDABC complements traditional QI initiatives by quantifying the highest cost steps and focusing QI initiatives to reduce costs and improve efficiency. As payment reform evolves toward bundled payments, TDABC and QI initiatives will help providers understand, communicate, and improve the value of cancer care., (Copyright © 2021.

Objective: To characterize full cycle of care costs for managing an acute ureteral stone using time-driven activity-based costing., Methods: We defined all phases of care for patients presenting with an acute ureteral stone and built an overarching process map. Maps for sub-processes were constructed through interviews with providers and direct observation of clinical spaces. This facilitated calculation of cost per minute for all aspects of care delivery, which were multiplied by associated process times. These were added to consumable costs to determine cost for each specific step and later aggregated to determine total cost for each sub-process. We compared costs of eight common clinical pathways for acute stone management, defining total cycle of care cost as the sum of all sub-processes that comprised each pathway., Results: Cost per sub-process included $920 for emergency department (ED) care, $1665 for operative stent placement, $2368 for percutaneous nephrostomy tube placement, $106 for urology clinic consultation, $238 for preoperative center visit, $4057 for ureteroscopy with laser lithotripsy (URS), $2923 for extracorporeal shock wave lithotripsy, $169 for clinic stent removal, $197 for abdominal x-ray, and $166 for ultrasound. The lowest cost pathway ($1388) was for medical expulsive therapy, whereas the most expensive pathway ($8002) entailed a repeat ED visit prompting temporizing stent placement and interval URS., Conclusion: We found a high degree of cost variation between care pathways common to management of acute ureteral stone episodes. Reliable cost accounting data and an understanding of variability in clinical pathway costs can inform value-based care redesign as payors move away from pure fee-for-service reimbursement., (Copyright © 2021 Elsevier Inc.

Purpose: To use time-drive activity-based costing (TDABC) to characterize and compare costs of transarterial chemoembolization (TACE), transarterial radioembolization (TARE), and ablation., Methods: This three-part study involved (1) prospective observation to record resources used during TACE, TARE, and ablation and statistical evaluation of interobserver and interprocedure variability; (2) Bland-Altman analysis of prospective measurements and medical record time stamps to establish practicality of using retrospective data in place of direct observation; (3) retrospective time stamp assessment for 117 ablations, 61 TACE procedures, and 61 TARE procedures to reveal variability drivers., Results: Ablation costs were lowest ($3,744), which were 74% of TACE costs ($5,089) and 18% of TARE costs ($20,818). Consumables were the greatest cost contributor, accounting for 65% of ablation, 58% of TACE, and 90% of TARE costs. A single consumable contributed to most of the overall costs: the ablation probe (42%), ethiodized oil for TACE (30%), and yttrium-90 microspheres for TARE (80%). Bland-Altman analysis showed agreement between retrospective time stamps and prospective measurements. Ablation costs increased from $3,288 to $4,245 to $4,461 for one, two, or three tumors treated. TACE cost increased from $5,051 to $5,296 for lobar versus selective approaches., Conclusion: A bottom-up costing approach using TDABC is feasible to assess true costs of hepatocellular carcinoma treatments and demonstrates ablation costs are significantly less than those of TACE and TARE. Replication of these methods at other institutions can facilitate development of a bundled payment model to promote utilization of locoregional therapies for hepatocellular carcinoma., (Copyright © 2021 American College of Radiology.

Purpose: In value-based health care delivery, radiation oncologists need to compare empiric costs of care delivery with advanced technologies, such as intensity-modulated proton therapy (IMPT) and intensity-modulated radiation therapy (IMRT). We used time-driven activity-based costing (TDABC) to compare the costs of delivering IMPT and IMRT in a case-matched pilot study of patients with newly diagnosed oropharyngeal (OPC) cancer., Materials and Methods: We used clinicopathologic factors to match 25 patients with OPC who received IMPT in 2011-12 with 25 patients with OPC treated with IMRT in 2000-09. Process maps were created for each multidisciplinary clinical activity (including chemotherapy and ancillary services) from initial consultation through 1 month of follow-up. Resource costs and times were determined for each activity. Each patient-specific activity was linked with a process map and TDABC over the full cycle of care. All calculated costs were normalized to the lowest-cost IMRT patient., Results: TDABC costs for IMRT were 1.00 to 3.33 times that of the lowest-cost IMRT patient (mean ± SD: 1.65 ± 0.56), while costs for IMPT were 1.88 to 4.32 times that of the lowest-cost IMRT patient (2.58 ± 0.39) ( P  < .05). Although single-fraction costs were 2.79 times higher for IMPT than for IMRT (owing to higher equipment costs), average full cycle cost of IMPT was 1.53 times higher than IMRT, suggesting that the initial cost increase is partly mitigated by reductions in costs for other, non-RT supportive health care services., Conclusions: In this matched sample, although IMPT was on average more costly than IMRT primarily owing to higher equipment costs, a subset of IMRT patients had similar costs to IMPT patients, owing to greater use of supportive care resources. Multidimensional patient outcomes and TDABC provide vital methodology for defining the value of radiation therapy modalities., Competing Interests: Conflicts of Interest: Steven J.

Background: There remains no tool to quantify the total value of comparative processes in health care. Hospital administrative data sets are emerging as valuable sources to evaluate performance. Thus, we use a framework to simultaneously assess multiple domains of value associated with an enhanced recovery initiative using national administrative data., Materials and Methods: Risk-stratified clinical pathways for patients undergoing pancreatic surgery were implemented in 2016 at our institution. We used a national administrative database to characterize changes in value associated with this initiative. Value metrics assessed included in-hospital mortality, complication rates, length of stay (LOS), 30-day readmission rates, and institutional costs. We compared our performance with other hospitals both before and after implementation of the pathways. Metrics were graphed on radar charts to assess overall value., Results: 22,660 cases were assessed. Comparing 75 cases at our institution and 5520 cases at all other hospitals before pathway implementation, mean in-hospital LOS was 9.6 versus 10.8 d, in-hospital mortality was 0.0% versus 1.9%, mean costs were $23,585 versus $21,387, 30-day readmission rates were 1.3% versus 7.4%, and complication rates were 8.0% versus 11.2%, respectively. Comparing 334 cases at our institution and 16,731 cases at all other hospitals after pathway implementation, mean in-hospital LOS was 7.7 versus 10.3 d, in-hospital mortality was 0.3% versus 1.6%, mean costs were $19,428 versus $22,032, 30-day readmission rates were 6.6% versus 7.5%, and complication rates were 6.3% versus 10.3%, respectively. Notably, LOS and institutional costs were reduced at our institution after implementation of the enhanced clinical care pathways. Our costs were higher than comparators before implementation, but lower than comparators after implementation., Conclusions: Herein, we used an analytic framework and used national administrative data to assess the value of an enhanced care initiative as benchmarked with data from other hospitals. We thus illustrate how to identify and measure opportunities for targeted improvements in health care delivery. We also recognize the limitations of the use of administrative data in a comprehensive assessment of value in health care., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: Cediranib, an oral anti-angiogenic VEGFR 1-3 inhibitor, was studied at a daily dose of 20 mg in combination with platinum-based chemotherapy and as maintenance in a randomised trial in patients with first relapse of 'platinum-sensitive' ovarian cancer and has been shown to improve progression-free survival (PFS)., Patients and Methods: ICON6 (NCT00532194) was an international three-arm, double-blind, placebo-controlled randomised trial. Between December 2007 and December 2011, 456 women were randomised, using stratification, to receive either chemotherapy with placebo throughout (arm A, reference); chemotherapy with concurrent cediranib, followed by maintenance placebo (arm B, concurrent); or chemotherapy with concurrent cediranib, followed by maintenance cediranib (arm C, maintenance). Due to an enforced redesign of the trial in September 2011, the primary endpoint became PFS between arms A and C which we have previously published, and the overall survival (OS) was defined as a secondary endpoint, which is reported here., Results: After a median follow-up of 25.6 months, strong evidence of an effect of concurrent plus maintenance cediranib on PFS was observed [hazard ratio (HR) 0.56, 95% confidence interval (CI) 0.44-0.72, P < 0.0001]. In this final update of the survival analysis, 90% of patients have died. There was a 7.4-month difference in median survival and an HR of 0.86 (95% CI: 0.67-1.11, P = 0.24) in favour of arm C. There was strong evidence of a departure from the assumption of non-proportionality using the Grambsch-Therneau test (P = 0.0031), making the HR difficult to interpret. Consequently, the restricted mean survival time (RMST) was used and the estimated difference over 6 years by the RMST was 4.8 months (95% CI: -0.09 to 9.74 months)., Conclusions: Although a statistically significant difference in time to progression was seen, the enforced curtailment in recruitment meant that the secondary analysis of OS was underpowered. The relative reduction in the risk of death of 14% risk of death was not conventionally statistically significant, but this improvement and the increase in the mean survival time in this analysis suggest that cediranib may have worthwhile activity in the treatment of recurrent ovarian cancer and that further research should be undertaken., Competing Interests: Disclosure ACE-T, HH, MV, ED, BP, LF, and AMS declare no conflicts of interest.

Background: False positive multiparametric magnetic resonance imaging (mpMRI) phenotypes prompt unnecessary biopsies. The Prostate MRI Imaging Study (PROMIS) provides a unique opportunity to explore such phenotypes in biopsy-naïve men with raised prostate-specific antigen (PSA) and suspected cancer., Objective: To compare mpMRI lesions in men with/without significant cancer on transperineal mapping biopsy (TPM)., Design, Setting, and Participants: PROMIS participants (n=235) underwent mpMRI followed by a combined biopsy procedure at University College London Hospital, including 5-mm TPM as the reference standard. Patients were divided into four mutually exclusive groups according to TPM findings: (1) no cancer, (2) insignificant cancer, (3) definition 2 significant cancer (Gleason ≥3+4 of any length and/or maximum cancer core length ≥4mm of any grade), and (4) definition 1 significant cancer (Gleason ≥4+3 of any length and/or maximum cancer core length ≥6mm of any grade)., Outcome Measurements and Statistical Analysis: Index and/or additional lesions present in 178 participants were compared between TPM groups in terms of number, conspicuity, volume, location, and radiological characteristics., Results and Limitations: Most lesions were located in the peripheral zone. More men with significant cancer had two or more lesions than those without significant disease (67% vs 37%; p< 0.001). In the former group, index lesions were larger (mean volume 0.68 vs 0.50 ml; p< 0.001, Wilcoxon test), more conspicuous (Likert 4-5: 79% vs 22%; p< 0.001), and diffusion restricted (mean apparent diffusion coefficient [ADC]: 0.73 vs 0.86; p< 0.001, Wilcoxon test). In men with Likert 3 index lesions, log 2 PSA density and index lesion ADC were significant predictors of definition 1/2 disease in a logistic regression model (mean cross-validated area under the receiver-operator characteristic curve: 0.77 [95% confidence interval: 0.67-0.87])., Conclusions: Significant cancer-associated MRI lesions in biopsy-naïve men have clinical-radiological differences, with lesions seen in prostates without significant disease. MRI-calculated PSA density and ADC could predict significant cancer in those with indeterminate MRI phenotypes., Patient Summary: Magnetic resonance imaging (MRI) lesions that mimic prostate cancer but are, in fact, benign prompt unnecessary biopsies in thousands of men with raised prostate-specific antigen. In this study we found that, on closer look, such false positive lesions have different features from cancerous ones. This means that doctors could potentially develop better tools to identify cancer on MRI and spare some patients from unnecessary biopsies., (Copyright © 2020 The Author(s).

Purpose: The DNA damage immune response (DDIR) assay was developed in breast cancer based on biology associated with deficiencies in homologous recombination and Fanconi anemia pathways. A positive DDIR call identifies patients likely to respond to platinum-based chemotherapies in breast and esophageal cancers. In colorectal cancer, there is currently no biomarker to predict response to oxaliplatin. We tested the ability of the DDIR assay to predict response to oxaliplatin-based chemotherapy in colorectal cancer and characterized the biology in DDIR-positive colorectal cancer., Experimental Design: Samples and clinical data were assessed according to DDIR status from patients who received either 5-fluorouracil (5-FU) or 5FUFA (bolus and infusion 5-FU with folinic acid) plus oxaliplatin (FOLFOX) within the FOCUS trial ( n = 361, stage IV), or neoadjuvant FOLFOX in the FOxTROT trial ( n = 97, stage II/III). Whole transcriptome, mutation, and IHC data of these samples were used to interrogate the biology of DDIR in colorectal cancer., Results: Contrary to our hypothesis, DDIR-negative patients displayed a trend toward improved outcome for oxaliplatin-based chemotherapy compared with DDIR-positive patients. DDIR positivity was associated with microsatellite instability (MSI) and colorectal molecular subtype 1. Refinement of the DDIR signature, based on overlapping IFN-related chemokine signaling associated with DDIR positivity across colorectal cancer and breast cancer cohorts, further confirmed that the DDIR assay did not have predictive value for oxaliplatin-based chemotherapy in colorectal cancer., Conclusions: DDIR positivity does not predict improved response following oxaliplatin treatment in colorectal cancer. However, data presented here suggest the potential of the DDIR assay in identifying immune-rich tumors that may benefit from immune checkpoint blockade, beyond current use of MSI status., (©2020 American Association for Cancer Research.)

Executive Summary: Postdischarge telephone calls by nurses can decrease patient return rates to healthcare systems. To date, call program costs have not been compared with patient return rates to determine cost-effectiveness. We used time-driven activity-based costing to determine the costs associated with such programs. We developed process maps for a postdischarge nurse call program in the emergency department of an urban, quaternary care, academic, Level 1 trauma center. Our primary outcome was the total cost of calls, which is based on the length of the calls (after 8 hours of observation) and the total capacity rate cost based on national registered nurse salary and space costs. Seven-day return rate differences between patients reached and those not reached from July 2018 to March 2019 were determined with a Z-test. We observed 113 postdischarge calls for 79 patients. The mean (SD) length of calls for patients reached was 4.3 minutes (1.8) compared with 2.6 minutes (0.6) for those not reached. The total capacity rate cost for calls was $1.09/minute, or $4.69 per patient reached and $2.83 per patient not reached. A retrospective analysis of 6,698 patients reached and 6,519 patients not reached showed hospital return rates of 3.5% and 6.3% (p < .0001), respectively. The study findings show that postdischarge calls were associated with decreased return rates to the emergency department and a savings of $134.89 per prevention of one return. In deciding whether to use postdischarge call programs, healthcare systems should also consider the effects on specific demographics and the potential benefits of greater patient satisfaction and increased treatment adherence.

Background: All risk stratification strategies in cancer overlook a spectrum of disease. The Prostate MR Imaging Study (PROMIS) provides a unique opportunity to explore cancers that are overlooked by multiparametric magnetic resonance imaging (mpMRI)., Objective: To summarise attributes of cancers that are systematically overlooked by mpMRI., Design, Setting, and Participants: PROMIS tested performance of mpMRI and transrectal ultrasonography (TRUS)-guided biopsy, using 5 mm template mapping (TPM) biopsy as the reference standard., Outcome Measurements and Statistical Analysis: Outcomes were overall and maximum Gleason scores, maximum cancer core length (MCCL), and prostate-specific antigen density (PSAD). Cancer attributes were compared between cancers that were overlooked and those that were detected., Results and Limitations: Of men with cancer, 7% (17/230; 95% confidence interval [CI] 4.4-12%) had significant disease overlooked by mpMRI according to definition 1 (Gleason ≥ 4 + 3 of any length or MCCL ≥ 6 mm of any grade) and 13% (44/331; 95% CI 9.8-17%) according to definition 2 (Gleason ≥ 3 + 4 of any length or MCCL ≥ 4 mm). In comparison, TRUS-guided biopsy overlooked 52% (119/230; 95% CI 45-58%) of significant disease by definition 1 and 40% (132/331; 95% CI 35-45%) by definition 2. Prostate cancers undetected by mpMRI had significantly lower overall and maximum Gleason scores (p = 0.0007; p < 0.0001) and shorter MCCL (median difference: 3 mm [5 vs 8 mm], p < 0.0001; 95% CI 1-3) than cancers that were detected. No tumours with overall Gleason score > 3 + 4 (Gleason Grade Groups 3-5; 95% CI 0-6.4%) or maximum Gleason score > 4 + 3 (Gleason Grade Groups 4-5; 95% CI 0-8.0%) on TPM biopsy were undetected by mpMRI. Application of a PSAD threshold of 0.15 reduced the proportion of men with undetected cancer to 5% (12/230; 95% CI 2.7-8.9%) for definition 1 and 9% (30/331; 95% CI 6.2-13%) for definition 2. Application of a PSAD threshold of 0.10 reduced the proportion of men with undetected disease to 3% (6/230; 95% CI 1.0-5.6%) for definition 1 cancer and to 3% (11/331; 95% CI 1.7-5.9%) for definition 2 cancer. Limitations were post hoc analysis and uncertain significance of undetected lesions., Conclusions: Overall, a small proportion of cancers are overlooked by mpMRI, with estimates ranging from 4.4% (lower boundary of 95% CI for definition 1) to 17% (upper boundary of 95% CI for definition 2). Prostate cancers undetected by mpMRI are of lower grade and shorter length than cancers that are detected., Patient Summary: Prostate cancers that are undetected by magnetic resonance imaging (MRI) are smaller and less aggressive than those that are detected, and none of the most aggressive cancers are overlooked by MRI., (Copyright © 2020 The Authors.

Rationale and Objectives: To quantify the costs and work of diagnostic radiology (DR) residents using the radiology key performance indicator turn-around time (TAT) as the outcome measure., Materials and Methods: In an Institutional Review Board-approved study, the annual cost of a DR resident was determined using salary, benefits, and a cost allocation of faculty effort. The volume of cases reported in the 2015-16 academic year and median and interquartile range (IQR) TAT for a trainee preliminary (Complete to Prelim, C-P) or an attending final (Complete to Final, C-F) radiology report were measured and stratified by time of day and patient location. Wilcoxon rank-sum tests were used (significance, p values < 0.05)., Results: The annual cost of a DR resident was $99,109, 34% greater than direct salary/benefits and 27% of the direct salary/benefits cost of an attending. The total per minute cost of rendering care was $4.36 with both trainee ($0.70/minute) and faculty ($3.66/minute). Residents participated in 139,084/235,417 (59%) imaging studies. The C-P TAT was 74 (IQR, 27-180) minutes compared to 51 (IQR, 18-129) minutes C-F TAT of faculty working alone and C-F TAT of 213 (IQR, 71-469) minutes with a resident (p < 0.001). The C-P TAT vs C-F TAT between 4 pm-9 am and weekends with residents is 44 (IQR, 18-119) minutes vs 60 (IQR, 18-179) minutes without., Conclusion: The cost of training DR residents exceeds the salary and benefits allocated to their training. Residents increase the absolute professional labor cost of caring for a patient. Overall TAT is slower with residents but the care delivered by residents after-hours is faster., (Copyright © 2019 The Association of University Radiologists. Published by Elsevier Inc.

Objective: Value-based care models are becoming instrumental in structuring clinical care delivery in our healthcare climate. Our objective was to determine the value associated with implementation of a Family-Centered Care Coordination (FCCC) program for neonates undergoing tracheostomy., Methods: A multi-disciplinary FCCC program was implemented at the Massachusetts Eye and Ear Infirmary and MassGeneral Hospital for Children in January 2013. This program is designed to ensure a safe transition out of the hospital for children undergoing tracheostomy, reduce re-admission rates, and increase caregiver quality of life (QOL). Study participants included neonates undergoing tracheostomy in 2012 and 2015. This retrospective cohort study examined length of stay (LOS), utilized time-driven activity-based costing to estimate the cost of care, assessed caregiver QOL with 1-month Pediatric Tracheostomy Health Status Instrument (PTHSI) scores, and assessed complications with 6-month Medical Complications Associated with Pediatric Tracheostomy (MCAT) scores., Results: Following implementation of the FCCC program, average LOS decreased from 30.5 days (range 17-39) to 16.6 days (range 9-23). The largest process improvement (cost reduction of 61%) occurred in the discharge-planning phase. The overall cost per care cycle was reduced by 36%. A large clinically meaningful benefit was demonstrated for PTHSI (effect size 0.80) as well as MCAT scores (effect size 9.35)., Conclusions: We demonstrated the higher outcomes, including reductions in caregiver burden and complication rates, and the lower costs associated with implementation of the FCCC program for neonates undergoing tracheostomy., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2020 Elsevier B.V.

Objective: To determine whether earlier hospital discharge is feasible and safe in selected patients with subarachnoid hemorrhage (SAH) using an outpatient "fast-track" protocol., Patients and Methods: We conducted a prospective quality improvement cohort study with the primary feasibility end point of patients with SAH deemed safe for discharge by treating team consensus. All patients received detailed education and outpatient transcranial Doppler monitoring; caregivers could contact the on-call team 24-7. Primary safety end points were adverse events after discharge and hospital readmission., Results: From January 1, 2010, to January 1, 2015, our center had 377 SAH diagnoses, of which 200 were included in the final cohort, 36 qualifying for fast-track early discharge. The 30-day readmission rate for fast-track patients was 11.0% (4 of 36) compared with 11.4% (18 of 164) for non-fast-track patients. The rate of delayed cerebral ischemia and stroke was 3% (1 of 36) in the fast-track group vs 25.0% (41 of 164) for the non-fast-track group. Adverse events occurred in 11.0% (4 of 36) of the fast-track group compared with 26.0% (43 of 164) in the non-fast-track group. The mean length of stay was reduced 60% from 15 days to 6.6 days in the fast-track group., Conclusion: Although our fast-track group was relatively small, data suggested early feasibility and safety in a carefully selected group of patients with SAH. Direct and indirect financial benefits of early discharge over a 5-year period were an estimated savings at least $864,000 in overall costs. A comparative effectiveness study is planned to replicate and validate these results using a larger multicenter design., (© 2020 Mayo Foundation for Medical Education and Research.

Background: Multiple modern Indian hospitals operate at very low cost while meeting US-equivalent quality accreditation standards. Though US hospitals face intensifying pressure to lower their cost, including proposals to extend Medicare payment rates to all admissions, the transferability of Indian hospitals' cost advantages to US peers remains unclear., Methods: Using time-driven activity-based costing methods, we estimate the average cost of personnel and space for an elective coronary artery bypass graft (CABG) surgery at two American hospitals and one Indian hospital (NH). All three hospitals are Joint Commission accredited and have reputations for use of modern performance management methods. Our case study applies several analytic steps to distinguish transferable from non-transferable sources of NH's cost savings., Results: After removing non-transferable sources of efficiency, NH's residual cost advantage primarily rests on shifting tasks to less-credentialed and/or less-experienced personnel who are supervised by highly-skilled personnel when perceived risk of complications is low. NH's high annual CABG volume facilitates such supervised work "downshifting." The study is subject to limitations inherent in case studies, does not account for the younger age of NH's patients, or capture savings attributable to NH's negligible frequency of re-admission or post-acute care facility placement., Conclusions: Most transferable bases for a modern Indian hospital's cost advantage would require more flexible American states' hospital and health professional licensing regulations, greater family participation in inpatient care, and stronger support by hospital executives and clinicians for substantially lowering the cost of care via regionalization of complex surgeries and weekend use of costly operating rooms., (Copyright © 2020 Elsevier Inc.

Background: Approximately half of high-grade serous ovarian carcinomas (HGSOCs) demonstrate homologous recombination repair (HR) pathway defects, resulting in a distinct clinical phenotype comprising hypersensitivity to platinum, superior clinical outcome, and greater sensitivity to poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors. EMSY, which is known to be amplified in breast and ovarian cancers, encodes a protein reported to bind and inactivate BRCA2. Thus, EMSY overexpression may mimic BRCA2 mutation, resulting in HR deficiency. However, to our knowledge, the phenotypic consequences of EMSY overexpression in HGSOC patients has not been explored., Methods: Here we investigate the impact of EMSY expression on clinical outcome and sensitivity to platinum-based chemotherapy using available data from transcriptomically characterized HGSOC cohorts., Results: High EMSY expression was associated with better clinical outcome in a cohort of 265 patients with HGSOC from Edinburgh (overall survival multivariable hazard ratio, 0.58 [95% CI, 0.38-0.88; P = .011] and progression-free survival multivariable hazard ratio, 0.62 [95% CI, 0.40-0.96; P = .030]). Superior outcome also was demonstrated in the Medical Research Council ICON7 clinical trial and multiple publicly available data sets. Patients within the Edinburgh cohort who had high EMSY expression were found to demonstrate greater rates of complete response to multiple platinum-containing chemotherapy regimens (radiological complete response rate of 44.4% vs 12.5% at second exposure; P = .035) and corresponding prolonged time to disease progression (median, 151.5 days vs 60.5 days after third platinum exposure; P = .004)., Conclusions: Patients with HGSOCs demonstrating high EMSY expression appear to experience prolonged survival and greater platinum sensitivity, reminiscent of BRCA-mutant cases. These data are consistent with the notion that EMSY overexpression may render HGSOCs HR deficient., (© 2019 University of Edinburgh.

In 2016 the newly appointed surgeon general of the Navy launched a value-based health care pilot project at Naval Hospital Jacksonville to explore whether multidisciplinary care teams (known as integrated practice units, or IPUs) and measurement of outcomes could improve the readiness of active duty personnel and lower the cost of delivering care to them, their dependents, and local retirees. This article describes the formation of the project's leadership structure, the selection of four conditions to be treated (low back pain, osteoarthritis, diabetes, and high-risk pregnancy), the creation of the care team for each condition, outcomes and costs measured, and the near-term changes in outcomes during the twelve-month pilot period. Patient outcomes improved for three of the four conditions. We describe factors that contributed to the project's success. After the pilot concluded, the Navy combined the back pain and osteoarthritis IPUs into a single musculoskeletal clinical unit and established a similar IPU at another naval hospital and its clinics. The diabetes IPU was continued, but the high-risk pregnancy IPU was not. We offer several observations on the elements that were key to the success of the project, explore challenges and opportunities, and suggest that the pilot described here could be taken to greater scale in the Military Health System and elsewhere.
