RESUMEN

BACKGROUND: Multispecialty management should be the preferred approach for the treatment of pelvic floor dysfunction because there is often multicompartmental prolapse. OBJECTIVE: To assess the safety of combined robotic ventral mesh rectopexy and either uterine or vaginal fixation for the treatment of multicompartmental pelvic organ prolapse at our institution. DESIGN: Retrospective analysis. SETTINGS: Tertiary referral academic center. PATIENTS: All patients who underwent a robotic approach and combined procedure and whose cases were discussed at a biweekly pelvic floor multidisciplinary team meeting. MAIN OUTCOME MEASURES: Operative time, intraoperative blood loss and complications, postoperative pelvic organ prolapse quantification score, length of stay, 30-day morbidity, and readmission. RESULTS: From 2018 to 2021, there were 321 operations for patients with multicompartmental prolapse. The mean age was 63.4 years. The predominant pelvic floor dysfunction was rectal prolapse in 170 cases (60%). Pelvic organ prolapse quantification scores were II in 146 patients (53%), III in 121 patients (44%), and IV in 9 patients (3%); 315 of 323 cases included robotic ventral mesh rectopexy (98%). Sacrocolpopexy or sacrohysteropexy was performed in 281 patients (89%). Other procedures included 175 hysterectomies (54%), 104 oophorectomies (32%), 151 sling procedures (47%), 149 posterior repairs (46%), and 138 cystocele repairs (43%). The operative time for ventral mesh rectopexy was 211 minutes and for combined pelvic floor reconstruction was 266 minutes. Average length of stay was 1.6 days. Eight patients were readmitted within 30 days: 1 with a severe headache and 7 with postoperative complications (2.5%), such as pelvic collection and perirectal collection, both requiring radiologic drainage. Four complications required reoperation: epidural abscess, small-bowel obstruction, missed enterotomy requiring resection, and urinary retention requiring sling revision. There were no mortalities. LIMITATIONS: Retrospective single-center study. CONCLUSIONS: A combined robotic approach for multicompartmental pelvic organ prolapse is a safe and viable procedure with a relatively low rate of morbidity and no mortality. This is the highest volume series of combined robotic pelvic floor reconstruction in the literature and demonstrates a low complication rate and short length of stay. See Video Abstract . RECTOPEXIA Y SACROCOLPOPEXIA ROBTICA VENTRAL COMBINADAS CON MALLA PARA EL PROLAPSO DE RGANOS PLVICOS MULTICOMPARTIMENTALES: ANTECEDENTES:El tratamiento multiespecializado debe ser el enfoque preferido para el tratamiento de la disfunción del suelo pélvico, ya que a menudo hay prolapso multicompartimental.OBJETIVO:Evaluar la seguridad de la rectopexia robótica combinada con malla ventral y fijación uterina o vaginal para el tratamiento del prolapso multicompartimental de órganos pélvicos en nuestra institución.DISEÑO:Análisis retrospectivo.AJUSTES:Centro académico de referencia terciarioPACIENTES:Todos los pacientes que se sometieron a un enfoque robótico y un procedimiento combinado y se discutieron en una reunión quincenal del equipo multidisciplinario sobre el piso pélvico.MEDIDAS DE RESULTADO:Tiempo operatorio, pérdida de sangre intraoperatoria y complicaciones. Puntuación de cuantificación del prolapso de órganos pélvicos posoperatorio, duración de la estancia hospitalaria, morbilidad a 30 días y reingreso.RESULTADOS:De 2018 a 2021, se realizaron 321 operaciones de pacientes con prolapso multicompartimental. La edad media fue 63.4 años. La disfunción del suelo pélvico predominante fue el prolapso rectal en 170 casos (60%). Las puntuaciones de cuantificación del prolapso de órganos pélvicos fueron II en 146 pacientes (53%), III en 121 (44%) y IV en 9 (3%); 315 de los 323 casos incluyeron rectopexia robótica de malla ventral (98%). Se realizó sacrocolpopexia o sacrohisteropexia en 281 pacientes (89%). Otros procedimientos incluyeron 175 histerectomías (54%), 104 ooforectomías (32%), 151 procedimientos de cabestrillo (47%), 149 reparaciones posteriores (46%) y 138 reparaciones de cistocele (43%). El tiempo operatorio para la rectopexia con malla ventral fue de 211 minutos y la reconstrucción combinada del piso pélvico de 266 minutos. La estancia media fue de 1.6 días. Ocho pacientes reingresaron dentro de los 30 días, 1 con dolor de cabeza intenso y 7 pacientes con complicaciones posoperatorias (2.5%): colección pélvica y colección perirrectal, ambas requirieron drenaje radiológico. Cuatro complicaciones requirieron reoperación: absceso epidural, obstrucción del intestino delgado, enterotomía omitida que requirió resección y retención urinaria que requirió revisión del cabestrillo. No hubo mortalidades.LIMITACIONES:Estudio retrospectivo unicéntrico.CONCLUSIONES:Un enfoque robótico combinado para el prolapso multicompartimental de órganos pélvicos es un procedimiento seguro y viable con una tasa relativamente baja de morbilidad y ninguna mortalidad. Esta es la serie de mayor volumen de reconstrucción robótica combinada del suelo pélvico en la literatura y demuestra una baja tasa de complicaciones y una estancia hospitalaria corta.

RESUMEN

Globally, collapse of ecosystems-potentially irreversible change to ecosystem structure, composition and function-imperils biodiversity, human health and well-being. We examine the current state and recent trajectories of 19 ecosystems, spanning 58° of latitude across 7.7 M km2 , from Australia's coral reefs to terrestrial Antarctica. Pressures from global climate change and regional human impacts, occurring as chronic 'presses' and/or acute 'pulses', drive ecosystem collapse. Ecosystem responses to 5-17 pressures were categorised as four collapse profiles-abrupt, smooth, stepped and fluctuating. The manifestation of widespread ecosystem collapse is a stark warning of the necessity to take action. We present a three-step assessment and management framework (3As Pathway Awareness, Anticipation and Action) to aid strategic and effective mitigation to alleviate further degradation to help secure our future.

RESUMEN

BACKGROUND: Splenectomies are widely performed, but there exists controversy regarding care for splenic injury patients. The purpose of this study is to provide a comprehensive review of the literature over the last 20 years for operative management (OM) versus nonoperative management (NOM) versus splenic artery embolization (SAE) for traumatic splenic injuries and associated outcomes. METHODS: A review of literature was performed following the PRISMA guidelines through a search of PubMed, EMBASE, Cochrane Library, JAMA Network, and SAGE journals from 2000 to 2020 regarding splenic injury in trauma patients and their management. Articles were then selected based on inclusion/exclusion criteria with GRADE criteria used on the included articles to assess quality. RESULTS: Twenty retrospective cohorts and one prospective cohort assessed patients who received OM versus NOM or SAE. Multiple studies indicated that NOM, in properly selected patients, provided better outcomes than its operative counterpart. CONCLUSION: This review provides additional evidence to support the NOM of splenic injuries for hemodynamically stable patients with benign abdomens as it accounts for consistently shorter hospital length of stay, fewer complications, and lower mortality than OM. For hemodynamically unstable patients, management continues to be intervention with surgery. More studies are needed to further investigate outcomes of post-splenectomy patients based on grade of injury, hemodynamic status, type of procedure (i.e., SAE), and failure of NOM in order to provide additional evidence and improve outcomes for this patient population.

RESUMEN

A pink to red-pigmented cryptophyte of undetermined taxonomic affinity was isolated and cloned from two seasonally ice-covered. meromictic, saline Antarctic aquatic environments: Bayly Bay (BB) and Ace Lake (AL). The clones shared a number of morphological and ultrastructural similarities with other cryptomonad genera, which confounded identification by light and electron microscopy. Cellular pigments extracted from the AL clone showed an absorption maximum corresponding to the biliprotein Cr-phycoerythrin 545, thus narrowing its potential taxonomic affinities. Partial 18S SSU ribosomal gene sequences were isolated from both the AL and the BB cryptomonads' nuclear rDNA, whereas PCR-amplified and their molecular phylogenies inferred from the subject sequences. Our results, and the results of another study that used our prepublished sequence data, invariably resolved both clones as very close matches with the Antarctic cryptophyte, Geminigera cryophila. When combined, the morphological, chemical, and molecular evidence suggested that both of our cryptophyte clones were a cryptomorph of the G. cryophila campylomorph. Slight differences between the AL and BB nuclear tree reconstructions suggested divergent microevolution following long-term isolation of the AL population from the surrounding marine ecosystem. This study provides further compelling evidence that certain Cryptophyceae engage in a life-history strategy, which includes alternating morphologically distinct cell-types (dimorphism); cell-types which without molecular analyses could be mistaken as novel taxa.

RESUMEN

BACKGROUND: Models that predict changes in the abundance and distribution of fauna under future climate change scenarios often assume that ecological niche and habitat availability are the major determinants of species' responses to climate change. However, individual species may have very different capacities to adapt to environmental change, as determined by intrinsic factors such as their dispersal ability, genetic diversity, generation time and rate of evolution. These intrinsic factors are usually excluded from forecasts of species' abundance and distribution changes. We aimed to determine the importance of these factors by comparing the impact of the most recent climate regime change, the late Pleistocene glacial-interglacial transition, on two sympatric, ice-dependent meso-predators, the emperor penguin (Aptenodytes forsteri) and Weddell seal (Leptonychotes weddellii). METHODS: We reconstructed the population trend of emperor penguins and Weddell seals in East Antarctica over the past 75,000 years using mitochondrial DNA sequences and an extended Bayesian skyline plot method. We also assessed patterns of contemporary population structure and genetic diversity. RESULTS: Despite their overlapping distributions and shared dependence on sea ice, our genetic data revealed very different responses to climate warming between these species. The emperor penguin population grew rapidly following the glacial-interglacial transition, but the size of the Weddell seal population did not change. The expansion of emperor penguin numbers during the warm Holocene may have been facilitated by their higher dispersal ability and gene flow among colonies, and fine-scale differences in preferred foraging locations. CONCLUSIONS: The vastly different climate change responses of two sympatric ice-dependent predators suggests that differing adaptive capacities and/or fine-scale niche differences can play a major role in species' climate change responses, and that adaptive capacity should be considered alongside niche and distribution in future species forecasts.

RESUMEN

Well-differentiated neuroendocrine tumors (NET) of the ileum are generally slow-growing tumors with metastatic potential that may cause systemic symptoms from the secretion of serotonin, cortisol, and other biologically active substances. Likewise, steroid cell tumors of the ovary are slow-growing tumors that cause systemic symptoms from the functional production of androgens, estrogens, and other hormones. To the best of our knowledge, synchronous ileal NET and ovarian steroid cell tumors have not been previously reported in the English literature. We present a case of a 59-yr-old woman with 2 primary tumors that were found incidentally: a Stage III (T2N1M0) 1.6 cm well-differentiated NET (NET G2) of the terminal ileum with metastasis to a mesenteric lymph node and a 2.4 cm steroid cell tumor of the left ovary. The patient had suffered from hyperandrogenism for several years before diagnosis of an ovarian steroid cell tumor, but had no symptoms attributable to the NET. From review of the literature, this is the first case description of these 2 primaries arising in the same individual.

RESUMEN

Interactions between DNA and transcription factors (TFs) guide cellular function and development, yet the complexities of gene regulation are still far from being understood. Such understanding is limited by a paucity of techniques with which to probe DNA-protein interactions. We have devised magnetic protein immobilization on enhancer DNA (MagPIE), a simple, rapid, multi-parametric assay using flow cytometric immunofluorescence to reveal interactions among TFs, chromatin structure and DNA. In MagPIE, synthesized DNA is bound to magnetic beads, which are then incubated with nuclear lysate, permitting sequence-specific binding by TFs, histones and methylation by native lysate factors that can be optionally inhibited with small molecules. Lysate protein-DNA binding is monitored by flow cytometric immunofluorescence, which allows for accurate comparative measurement of TF-DNA affinity. Combinatorial fluorescent staining allows simultaneous analysis of sequence-specific TF-DNA interaction and chromatin modification. MagPIE provides a simple and robust method to analyze complex epigenetic interactions in vitro.

RESUMEN

As the effects of regional climate change are most pronounced at polar latitudes, we might expect polar-ward migratory populations to respond as habitat suitability changes. The southern elephant seal (Mirounga leonina L.) is a pole-ward migratory species whose populations have mostly stabilized or increased in the past decade, the one exception being the Macquarie Island population which has decreased continuously over the past 50 years. To explore probable causes of this anomalous trend, we counted breeding female seals annually between 1988 and 2011 in order to relate annual rates of population change (r) to foraging habitat changes that have known connections with atmospheric variability. We found r (i) varied annually from -0.016 to 0.021 over the study period, (ii) was most effected by anomalous atmospheric variability after a 3 year time lag was introduced (R = 0.51) and (iii) was associated with sea-ice duration (SID) within the seals' foraging range at the same temporal lag. Negative r years may be extrapolated to explain, at least partially, the overall trend in seal abundance at Macquarie Island; specifically, increasing SID within the seals foraging range has a negative influence on their abundance at the island. Evidence is accruing that suggests southern elephant seal populations may respond positively to a reduced sea-ice field.

RESUMEN

OBJECTIVE: The newest findings on literature utilization relevant to gynecologic oncology were published by Thomson Reuters during June 2013 as determinants of journal standing. Our objective was to assess the different metrics reported for relative impact and cost for journals relevant to gynecologic oncology. METHODS: 55 journals were evaluated for Impact Factor (IF), 5 Year IF, Immediacy Index, Cited Half Life, Eigenfactor (EF) Score, Article Influence (AI) scores and subscription costs obtained from publisher information. RESULTS: CA-A Cancer Journal for Clinicians had the highest IF (101.78) & AI (24.502). The top EF cancer-specific journals were the Journal of Clinical Oncology, Cancer Research, Clinical Cancer Research and Oncogene. Rankings for Gynecologic Oncology (409 articles, 18,243 citations) were IF = 3.929, 43/55, EF = 0.038, 28/55, and AI = 1.099, 44/55, all higher than the previous year. The IF improved from the 5 year IF in 31 journals, including Gynecologic Oncology, 29/31. Subscription costs for Gynecologic Oncology compared favorably to other journals. CONCLUSIONS: The high utilization of review information in CA-A Cancer Journal for Clinicians and Nature Review Cancer illustrated by the IF coupled with a relatively low number of articles and short cited half life indicates that they serve as a leading source of quoted cancer statistics (CA-A Cancer Journal for Clinicians). Rankings for Gynecologic Oncology and the International Journal of Gynecologic Cancer have improved. Regardless of specialty size, the Impact Factor for Gynecologic Oncology is respectably strong. The decreased IF in 44% of the journals may reflect the international economy's effect on cancer research.

RESUMEN

OBJECTIVE: Transvaginal ultrasonography with tumor morphology index (MI) has been used to predict the risk of ovarian malignancy. Our objective was to analyze changes in serial MI scores for malignant and non-malignant ovarian tumors in a large and asymptomatic population. METHODS: Eligible subjects participated in the University of Kentucky Ovarian Cancer Screening Program and had abnormalities that included cysts, cysts with septations, complex cysts with solid areas, and solid masses. Analysis included: MI, change in MI (delta MI), delta MI per scan and per month, number and duration of scans. RESULTS: From 1987 to 2012, 38,983 women received 218,445 scans. Of the 7104 eligible subjects, 6758 tumors were observed without surgery and 472 were surgically removed. Eighty-six percent (5811) of observed tumors were resolved. There were 74 malignant and 272 non-malignant tumors. Eighty-five percent of malignancies had MI ≥5 at decision for surgery. The risk of malignancy based on MI was: MI=5 (3%), MI=6 (3.7%), MI=7 (12.6%), MI=8 (26.7%), MI=9 (27.8%), MI=10 (33.3%). The mean delta MI per month decreased for tumors that resolved (delta MI -1.0, p<0.001) or persisted without surgery (delta MI -0.7, p<0.001). For abnormalities surgically removed, the mean delta MI per month increased significantly more for malignancies than for benign tumors (delta MI +1.6 vs. +0.3, p<0.001). CONCLUSIONS: The mean MI for malignant ovarian tumors increases over time, while non-malignant tumors have a decreasing or stable MI. Serial MI analysis can improve the prediction of ovarian malignancy by reducing false-positive results, thereby decreasing the number of operations performed for benign abnormalities.

RESUMEN

OBJECTIVE: The aim of this study was to conduct a detailed geospatial analysis of mobile phone signal coverage in the northwest macro-region of Paraná State, Brazil, seeking to identify areas where limitations in coverage may be related to lengthy travel times of the helicopter emergency medical service (HEMS) for the assistance of victims of road traffic injuries (RTIs). METHODS: An observational study was conducted to examine mobile phone signal coverage and HEMS travel times from 2017 to 2021. HEMS travel times were categorized into four groups: T1 (0-15 min), T2 (16-30 min), T3 (31-45 min), and T4 (over 45 min). Empirical Bayesian Kriging was used to map areas with low mobile signal coverage. The Kruskal-Wallis test and Dwass-Steel-Critchlow-Fligner comparative analyses were performed to explore how mobile signal coverage relates to HEMS travel times to RTI locations. RESULTS: There were 470 occurrences of RTIs attended by HEMS, of which 108 (23%) resulted in on-site fatalities. Among these deaths, 47 (26.85%) occurred in areas with low mobile phone signal coverage ("shadow areas"). Low mobile phone signal coverage identified at 175 (37.24%) RTIs locations, was unevenly distributed across the macro-region. The lowest medians of mobile signal quality were predominantly found in areas with HEMS travel times exceeding 30 min, corresponding to signal strength values of -98.44 (T3) and -100.75 (T4) dBm. This scenario represents a challenge for effective communication to activate HEMS. In the multiple comparison analysis among travel time groups, significant differences were observed between T1 and T2 (p < 0.001), T1 and T3 (p < 0.001), T1 and T4 (p < 0.001), and T2 and T3 (p < 0.001), indicating a potential association between lower mobile phone signal coverage and longer HEMS travel times. CONCLUSION: It can be concluded that poor mobile phone signals in remote areas can hinder HEMS activation, potentially delaying the start of treatment for RTIs. Identification of the shadow areas can help communication and health managers in designing and implementing the necessary changes to improve mobile phone signal coverage and consequently reduce delays in the initial response to RTIs.

RESUMEN

Historically, king penguin populations on Macquarie Island have suffered greatly from human exploitation. Two large colonies on the island were drastically reduced to a single small colony as a result of harvesting for the blubber oil industry. However, recent conservation efforts have resulted in the king penguin population expanding in numbers and range to recolonize previous as well as new sites. Ancient DNA methods were used to estimate past genetic diversity and combined with studies of modern populations, we are now able to compare past levels of variation with extant populations on northern Macquarie Island. The ancient and modern populations are closely related and show a similar level of genetic diversity. These results suggest that the king penguin population has recovered past genetic diversity in just 80 years owing to conservation efforts, despite having seen the brink of extinction.

RESUMEN

OBJECTIVE: To explore clinical correlates of wound complications in high-risk women undergoing abdominal gynecologic surgery in a tertiary referral center. METHODS: Retrospective analysis of patient demographics, pre-operative and intra-operative information, and outcomes was performed in a cohort of patients who underwent abdominal surgery for suspected gynecologic malignancy between 1/2005 and 6/2008. The primary outcome was wound complication within 6 weeks of surgery. Univariate and multivariate logistic regression analyses were employed. A nomogram predicting post-operative wound complications was created and validated by receiver operating characteristic (ROC) curve analysis and 10-fold cross-validation. RESULTS: Median age of 373 women analyzed was 57years (range 25-88), median body mass index (BMI) 32.3kg/m(2) (range 14.0-70.7). A total of 150 patients (40%) had prior abdominal surgery; 40 (11%) had a pre-operative serum albumin <3.5g/dl; and 78 (21%) had pulmonary disease. Wound complications occurred in 125 patients (34%). In multivariate analysis wound complications were correlated with BMI of 30-39.9kg/m(2) (OR=5.62, 95% CI 2.08-15.19, p<0.0001) and BMI≥40kg/m(2) (OR=10.27, 95% CI 3.66-28.88, p<0.0001), prior abdominal surgery (OR 3.28, 95%CI1.89-5.70, p<0.0001), serum albumin≤3.5g/dl (OR 4.24, 95%CI 1.87-9.61, p=0.0005), pulmonary disease (OR 2.22, 95%CI 1.09-4.51, p=0.03), lysis of adhesions (OR 3.57, 95%CI 1.04-12.26, p=0.04), and length of surgery (OR 2.42, 95%CI 1.35-4.35, p=0.003). Risk for wound complication was lower with pelvic drain placement (OR 0.26, 95%CI 0.11-0.64, p=0.003). CONCLUSIONS: Wound complications are common in gynecologic oncology. Further studies should explore whether risk factor modification decreases complications.

RESUMEN

BACKGROUND: Research productivity is critical to academic surgery and essential for advancing surgical knowledge and evidence-based practice. We aim to determine if surgeon affiliation with top US universities/hospitals (TOPS) is associated with increased research productivity measured by numbers of peer-reviewed publications in PubMed (PMIDs). METHODS: A bibliometric analysis was performed for PMIDs. Affiliated authors who published in trauma surgery (TS), surgical critical care (SCC), acute care surgery (ACS), and emergency general surgery (EGS) were evaluated for publications between 2015 and 2019, and lifetime productivity. Our analysis included 3443 authors from 443 different institutions. Our main outcome was PMIDs of first author (FA) and senior author (SA) in each field (2015-2019) and total lifetime publications. RESULTS: Significant differences exist between PMIDs from TOPS vs non-TOPS in FA-TS (1.34 vs 1.23, P = .001), SA-TS (1.71 vs 1.46, P < .001), total SA-PMIDs (44.10 vs 26.61, P < .001), and SA-lifetime PMIDs (90.55 vs 59.03, P < .001). There were no significant differences in PMIDs for FA or SA-SCC, FA or SA-ACS, FA or SA-EGS, FA-total PMIDs 2015-2019, or FA-lifetime PMIDs (P > .05 for all). CONCLUSION: There were significantly higher TS PMIDs among FAs and SAs affiliated with top US institutions in 2015-2019, along with higher total PMIDs (2015-2019) and lifetime PMIDs. These findings are of significance to future graduate medical applicants and academic surgeons who need to make decisions about training and future career opportunities.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the effect of number of chemotherapy cycles and other clinical and pathologic factors on progression-free (PFS) and overall survival (OS) in patients with newly diagnosed cervical cancer. METHODS: We identified 118 patients with locally advanced cervical cancer (stages IB2-IVA) treated with combination weekly cisplatin (40 mg/m(2)) and radiation therapy (RT) between 2003 and 2007. Kaplan-Meier and Cox proportional hazard models were utilized to evaluate PFS and OS for associations with number of chemotherapy cycles and other factors. RESULTS: The majority of patients had stage IB2 or II disease (70%), squamous histology (91%), and size <6 cm (65%). Median RT duration was 50 days and 95% received brachytherapy. Thirty percent of patients completed <6 cycles of chemotherapy, and estimated PFS and OS were 63% and 75%, respectively. In multivariate analyses, the number of chemotherapy cycles was independently predictive of PFS and OS. Patients who received <6 cycles of cisplatin had a worse PFS (HR 2.65; 95% CI 1.35-5.17; p=0.0045) and OS (HR 4.47; 95% CI 1.83-10.9; p=0.001). Advanced stage, longer time to RT completion, and absence of brachytherapy were also associated with decreased OS and PFS (p<0.05). Similar results were found when analysis was conducted using a breakpoint of at least five but not less than five chemotherapy cycles. Higher grade was associated with decreased PFS (p=0.03) but not OS. Age, race, BMI, tumor size, smoking, histology, and IMRT were not statistically significant for OS or PFS. CONCLUSIONS: Aggressive supportive care to minimize missed chemotherapy treatments may improve survival after chemoradiation.

RESUMEN

BACKGROUND AND OBJECTIVES: Fee for service (FFS), the dominant payment model for primary care in the United States, compensates physicians based on volume. There are many initiatives exploring alternative payment models that prioritize value over volume. The Family Medicine for America's Health (FMAHealth) Payment Team has developed a comprehensive primary care payment (CPCP) model to support the move from activity- and volume-based payment to performance-based payment for value. METHODS: In 2016-2017, the FMAHealth Payment Team performed a comprehensive study of the current state of primary care payment models in the United States. This study explored the features, motivations, successes, and failures of a wide variety of payment arrangements. RESULTS: The results of this work have informed a definition of comprehensive primary care payment (CPCP) as well as a CPCP calculator. This quantitative methodology calculates a base rate and includes modifiers that recognize the importance of infrastructure and resources that have been found to be successful in innovative models. The modifiers also incorporate adjustments for chronic disease burden, social determinants of health, quality, and utilization. CONCLUSIONS: The calculator and CPCP methodology offer a potential roadmap for transitioning from volume to value and details how to calculate such an adjustable comprehensive payment. This has impact and interest for all levels of the health care system and is intended for use by practices of all types as well as health systems, employers, and payers.

RESUMEN

To determine how obstetricians and gynecologists (OB/GYNs) perceive the gynecologic health effects of obesity and to identify perceived obstacles to counseling. OB/GYNs with 3 St. Louis health systems were emailed a 46-question survey regarding physicians' role in counseling women on the health risks of obesity and barriers faced in achieving this counseling. Differences between respondents' gender, age, practice type, years in practice, and body mass index were assessed using Chi-square or Fisher's exact tests as appropriate. Of 318 OB/GYNs emailed, 134 completed surveys, including 82 generalists and 52 subspecialists. 93% of respondents believed it was necessary to educate patients on health risks of obesity. 90% and 75%, respectively, cited diagnoses of endometrial hyperplasia and cancer as teachable moments for counseling. The most frequently cited barriers to successful counseling were lack of time, referral services, and patient tools/information. Most did not believe they had adequate reimbursement (65%), training (53%) or educational resources (50%) to counsel patients. Survey answers differed by practice setting, gender, and provider age. Although most OB/GYN providers consider obesity counseling important, execution is hindered by perceived barriers that differ by provider gender, age, and practice type. For OB/GYNs, more effective weight management counseling will require better training and practice-specific strategies. Based on survey responses, better reimbursement combined with increased resources for appropriate referrals and cancer prevention counseling are needed in order to improve weight management implementation in OB/GYN. •The majority of OB/GYNs believe obesity counseling is important•Perceptions of obesity counseling differ based on provider/practice characteristics.•Lack of time, referral services, and patient tools are the biggest cited barriers to counseling.•Improved obesity counseling could improve downstream OB/GYN morbidities.
