O trabalho em associações e cooperativas: os empreendimentos, redes de contato e saúde dos trabalhadores / Work in associations and cooperatives: enterprises, contact networks and workers’ health

Esta pesquisa buscou analisar o trabalho em associações e cooperativas de trabalho situadas no Nordeste do Brasil. Trata-se de um estudo qualitativo envolvendo doze instituições, investiga-das por meio de um questionário e seis entrevistas com associados. As respostas ao questioná-rio foram analisadas utilizando o método QCA (Análise Qualitativa Comparativa) e as entrevis-tas pela técnica de análise de conteúdo. Evidenciou-se a importância do apoio fornecido por atores sociais externos aos empreendimentos, mas também uma avaliação negativa da gestão. A criação desses empreendimentos se configura como uma oportunidade de trabalho e renda para a maioria dos entrevistados. Notou-se, no entanto, a falta de preocupação com a saúde dos associados e os cuidados necessários para reduzir os riscos de acidentes, incluindo a expo-sição frequente a materiais perigosos e contaminados, bem como incertezas, estresses no am-biente de trabalho, cargas de trabalho excessivas e conflitos interpessoais. Estes últimos po-dem contribuir para acidentes e doenças ocupacionais. (AU)

This research aimed to analyze the work in labor associations and cooperatives located in northeastern Brazil. This is a qualitative study involving twelve institutions, investigated through a questionnaire and six interviews with associates. The answers to the questionnaire were analyzed using the QCA (Comparative Qualitative Analysis) method, and the interviews were conducted using the content analysis technique. The importance of the support provided by social actors external to the enterprises was highlighted, but also a negative evaluation of the management. The creation of these enterprises is configured as an opportunity for work and income for most of the interviewees. However, there was a lack of concern for the health of associates and the necessary care to reduce the risk of accidents, including frequent expo-sure to hazardous and contaminated materials, as well as uncertainties, stresses in the work environment, excessive workloads and interpersonal conflicts. The latter can contribute to oc-cupational accidents and illnesses. (AU)

Organizational political affiliation and job seekers: If I don't identify with your party, am I still attracted?

Political divisions appear to be relatively frequent in today's world. Indeed, individuals on opposing sides of these divisions often view each other very negatively. The present multi-study investigation contributes to the nascent literature on organizational political affiliation by examining how job seekers view organizations with political affiliations, a practice that is becoming more prevalent. Studies 1 and 2 indicated that many job seekers are aware of organizations' political affiliations or stances, and that they often considered these affiliations and stances during recent job searches. For example, nearly one-third of participants said they did not apply to an organization because of its political affiliation or stances. Study 3 showed that the extent to which job seekers identified with the organization's party affiliation positively influenced their reactions toward the organization (e.g., perceived similarity and liking), as well as their intention to pursue employment with the organization. In contrast, job seekers' disidentification with the organization's affiliation decreased their feelings of perceived similarity and liking. Study 4 demonstrated that organizational affiliation with a political issue (i.e., gun control/second amendment) also influenced perceptions of similarity and liking. Taken together, results suggest that organizations' affiliations with political parties or their stances on political issues can influence the amount and types of potential employees that organizations attract.

Association of Multiple Hospital Affiliations With Clinician Service Use, Breadth of Procedures, and Costs.

Importance: Little is known about whether a clinician having multiple hospital affiliations (ie, 1 clinician working across multiple teams and organizations) is associated with clinician practice style and cost. The measurement of this association requires adjusting for selection into multihospital affiliations based on both observable and unobservable clinician characteristics. Objective: To evaluate the association of multiple hospital affiliations with clinician service use, breadth of procedures used, and costs. Design, Setting, and Participants: This cohort study used Medicare Part B data from 2016 through 2017 in a fixed-effects panel data design to compare service use, procedure breadth, and costs between clinicians with multiple affiliations (treatment group) and clinicians with a single affiliation (control group), with adjustment for volume, patients, and clinician characteristics. The study also controlled for unobserved (time-invariant) clinician characteristics using individual clinician fixed effects. Clinicians with Medicare claims, a reported National Provider Identifier, and affiliation data within Medicare Physician Compare were included for a total sample of 1 073 252 observations (633 552 unique clinicians) for medical services and 358 669 observations (210 260 unique clinicians) for drug prescribing. Statistical analyses were performed from February 1 to October 15, 2021. Main Outcomes and Measures: Service use is the total number of medical (or drug) services that clinicians render to their Medicare beneficiaries within a given year, procedure breadth is the total number of unique Healthcare Common Procedure Coding System codes that are associated with clinicians' medical (or drug) services within a given year, and costs represent the total standardized amount paid by Medicare for the medical (or drug) services. Additional measures were multiple-hospital affiliations, Accountable Care Organization affiliation, and controls across clinician and patient characteristics. Results: The medical service sample consisted of 633 552 clinicians (248 359 women [39.2%]; mean [SD] of 19.6 [12.5] years of experience), and the drug service sample consisted of 210 260 clinicians (74 875 women [35.6%]; mean [SD] of 21.6 [12.3] years of experience). For medical services, clinicians with multiple practice affiliations used a mean 8.2% (95% CI, 7.5%-8.9%; P < .001) more medical services per patient, drew on a mean 5.4% (95% CI, 5.1%-5.7%; P < .001) wider set of procedures within their medical care, and incurred a mean 8.6% (95% CI, 7.9%-9.2%; P < .001) more in medical costs. Pertaining to drug services, clinicians with multiple practice affiliations used a mean 2.9% (95% CI, 1.9%-3.9%; P < .001) more drug services per patient, drew on a mean 1.0% (95% CI, 0.5%-1.4%; P < .001) wider set of procedures within their medical care, and incurred a mean 2.7% (95% CI, 1.6%-3.7%; P < .001) more in drug costs. Significant results were also found across extensive and intensive margins of hospital affiliation, and supplemental analysis further indicated heterogenous treatment associations across clinician specialties. Conclusions and Relevance: This cohort study found that a clinician having multihospital affiliations was associated with greater service use, procedure breadth, and costs across both medical and drug services. These findings suggest that clinician affiliations ought to be considered as part of health care delivery design and potential cost-containment strategies.

Local COVID-19 Epicenter in Detroit Metropolitan Area Causing Profound and Pervasive Reorganization of Clinical, Educational, Research, and Financial Programs of a Large Academic Gastroenterology Division with a GI Fellowship and Primary Medical School Affiliation.

AIM: To report revolutionary reorganization of academic gastroenterology division from COVID-19 pandemic surge at metropolitan Detroit epicenter from 0 infected patients on March 9, 2020, to > 300 infected patients in hospital census in April 2020 and > 200 infected patients in April 2021. SETTING: GI Division, William Beaumont Hospital, Royal Oak, has 36 GI clinical faculty; performs > 23,000 endoscopies annually; fully accredited GI fellowship since 1973; employs > 400 house staff annually since 1995; tertiary academic hospital; predominantly voluntary attendings; and primary teaching hospital, Oakland-University-Medical-School. METHODS: This was a prospective study. Expert opinion. Personal experience includes Hospital GI chief > 14 years until 2020; GI fellowship program director, several hospitals > 20 years; author of > 300 publications in peer-reviewed GI journals; committee-member, Food-and-Drug-Administration-GI-Advisory Committee > 5 years; and key hospital/medical school committee memberships. Computerized PubMed literature review was performed on hospital changes and pandemic. Study was exempted/approved by Hospital IRB, April 14, 2020. RESULTS: Division reorganized patient care to add clinical capacity and minimize risks to staff of contracting COVID-19 infection. Affiliated medical school changes included: changing "live" to virtual lectures; canceling medical student GI electives; exempting medical students from treating COVID-19-infected patients; and graduating medical students on time despite partly missing clinical electives. Division was reorganized by changing "live" GI lectures to virtual lectures; four GI fellows temporarily reassigned as medical attendings supervising COVID-19-infected patients; temporarily mandated intubation of COVID-19-infected patients for esophagogastroduodenoscopy; postponing elective GI endoscopies; and reducing average number of endoscopies from 100 to 4 per weekday during pandemic peak! GI clinic visits reduced by half (postponing non-urgent visits), and physical visits replaced by virtual visits. Economic pandemic impact included temporary, hospital deficit subsequently relieved by federal grants; hospital employee terminations/furloughs; and severe temporary decline in GI practitioner's income during surge. Hospital temporarily enhanced security and gradually ameliorated facemask shortage. GI program director contacted GI fellows twice weekly to ameliorate pandemic-induced stress. Divisional parties held virtually. GI fellowship applicants interviewed virtually. Graduate medical education changes included weekly committee meetings to monitor pandemic-induced changes; program managers working from home; canceling ACGME annual fellowship survey, changing ACGME physical to virtual site visits; and changing national conventions from physical to virtual. CONCLUSION: Reports profound and pervasive GI divisional changes to maximize clinical resources devoted to COVID-19-infected patients and minimize risks of transmitting infection.

La afiliación al sistema de salud de personas migrantes venezolanas en Colombia / The Affiliation to the Health System among Venezuelan Migrants in Colombia

Resumen: Introducción:El acceso de las personas migrantes venezolanas al sistema de salud es fundamental para su supervivencia y bienestar futuro. El objetivo de esta investigación es analizar los niveles de afiliación a dicho sistema de las personas venezolanas en las áreas urbanas de Colombia por periodos de arribo, así como los factores sociodemográficos y laborales asociados. Metodología: Se realiza análisis cuantitativo de tipo estadístico descriptivo e inferencial, a partir de la Gran Encuesta Integrada de Hogares 2018, la cual aporta datos representativos para Colombia y sus 13 ciudades más importantes. Se utilizan los módulos de migración, de variables sociodemográficas del hogar y de ocupación relativos a la población de 14 a 65 años. Resultados:Únicamente 24,5 % de dichos migrantes están inscritos al sistema de salud en contraste a 93 % de las personas colombianas. Los niveles de afiliación se redujeron de 82 % entre las personas venezolanos que arribaron en 2013 o antes a 10 % entre los que llegaron en 2017-2018. Las personas venezolanas afiliadas al sistema de salud son una población selecta en términos sociodemográficos; más joven, más educada, con mayor participación laboral y mayores ingresos que la población nativa en Colombia. La baja inserción de las personas migrantes venezolanas en empleos con contrato escrito restringe dicha afiliación. Conclusiones: Las personas venezolanas en Colombia tienen muy limitada la inscripción al sistema de salud. A pesar de que este es un derecho protegido por los marcos jurídicos internacional y nacional, estas personas enfrentan barreras económicas, políticas y sociales para ejercer ese derecho en Colombia.

Abstract: Introduction: Venezuelan migrants' access to the health system is fundamental to their survival and future well-being. This article aims to analyze the level of affiliation to the health care system of these migrants in the urban areas in Colombia by arrival periods and the associated sociodemographic and labor factors. Methodology: To this end, quantitative analysis is done based on descriptive and inferential statistical analyses of the 2018 Gran Encuesta Integrada de Hogares, which is a representative survey for Colombia and its 13 more important urban areas. We use the modules on migration, sociodemographic variables of the household and occupation relative to the population aged 14 to 65. Results: Only 24,5% of Venezuelan migrants are affiliated with any health care provider in contrast to 93% of Colombians. The levels of affiliation diminished from 82% among Venezuelans who arrived in 2013 or before to 10% among Venezuelans who arrived in 2017-2018. Venezuelans registered in the health system are a select population in sociodemographic terms; younger, more educated, with more labor participation and higher income than the native population in Colombia. The low insertion of Venezuelan immigrants in jobs with a written contract restricts this enrollment. Conclusions:The Venezuelans in Colombia have a very limited affiliation with the health system. Even though this is a right protected by international and national legal frameworks, Venezuelans encounter economic, political, and social barriers to exercise it in Colombia.

The Impact of Hospital/University Affiliation on Research Productivity Among US-Based Authors in the Fields of Trauma, Surgical Critical Care, Acute Care, and Emergency General Surgery.

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.

Does Community- or University-Based Residency Sponsorship Affect Graduate Perceived Preparation or Performance?

BACKGROUND: Residency training occurs in varied settings. Whether there are differences in the training received by graduates of community- or medical school-based programs has been the subject of debate. OBJECTIVE: This study examined the perceived preparation for practice, scope of practice, and American Board of Family Medicine (ABFM) board examination pass rates of family physicians in relation to the type of residency program (community, medical school, or partnership) in which they trained. METHODS: Predetermined survey responses were abstracted from the 2016 and 2017 National Family Medicine Graduate Survey of ABFM and linked to data about residency programs obtained from the websites of national organizations. Descriptive statistics were used to summarize the data and logistic regression to examine differences between survey results based on type of residency training: community, medical school, or partnership. RESULTS: Differences in the perception of preparation as well as current scope of practice were noted for the 3 residency types. The differences in perception were mainly noted in hospital-based skills, such as intubation and ventilator management, and in women's health and family planning services, with different program types increasing preparedness perception in different domains. CONCLUSIONS: In general, graduates of family medicine community-based, non-affiliated, and partnership programs perceived they were prepared for and were providing more of the services queried in the survey than graduates of medical school-based programs.

Multi-Institution Research and Education Collaboration Identifies New Antimicrobial Compounds.

New antibiotics are urgently needed to address increasing rates of multidrug resistant infections. Seventy-six diversely functionalized compounds, comprising five structural scaffolds, were synthesized and tested for their ability to inhibit microbial growth. Twenty-six compounds showed activity in the primary phenotypic screen at the Community for Open Antimicrobial Drug Discovery (CO-ADD). Follow-up testing of active molecules confirmed that two unnatural dipeptides inhibit the growth of Cryptococcus neoformans with a minimum inhibitory concentration (MIC) ≤ 8 µg/mL. Syntheses were carried out by undergraduate students at five schools implementing Distributed Drug Discovery (D3) programs. This report showcases that a collaborative research and educational process is a powerful approach to discover new molecules inhibiting microbial growth. Educational gains for students engaged in this project are highlighted in parallel to the research advances. Aspects of D3 that contribute to its success, including an emphasis on reproducibility of procedures, are discussed to underscore the power of this approach to solve important research problems and to inform other coupled chemical biology research and teaching endeavors.

CONCLUSIONES: tras analizar las causas, se propuso varias medidas para corregir dicha pérdida

OBJECTIVE: The variability of the affiliations of a health institution in the Scopus database is analyzed and how it influences the recovery of scientific production is studied. METHODS: Searches were conducted by authors, strategy and standardized name of the institution to compare the variability of the results. RESULTS: There is a loss of 44.20% of documents in the recovery by the standardized affiliation field of the database. CONCLUSIONS: After analysing the causes, a number of measures are proposed to correct this loss

Association of Clinician Health System Affiliation With Outpatient Performance Ratings in the Medicare Merit-based Incentive Payment System.

Importance: Integration of physician practices into health systems composed of hospitals and multispecialty practices is increasing in the era of value-based payment. It is unknown how clinicians who affiliate with such health systems perform under the new mandatory Centers for Medicare & Medicaid Services Merit-based Incentive Payment System (MIPS) relative to their peers. Objective: To assess the relationship between the health system affiliations of clinicians and their performance scores and value-based reimbursement under the 2019 MIPS. Design, Setting, and Participants: Publicly reported data on 636 552 clinicians working at outpatient clinics across the US were used to assess the association of the affiliation status of clinicians within the 609 health systems with their 2019 final MIPS performance score and value-based reimbursement (both based on clinician performance in 2017), adjusting for clinician, patient, and practice area characteristics. Exposures: Health system affiliation vs no affiliation. Main Outcomes and Measures: The primary outcome was final MIPS performance score (range, 0-100; higher scores intended to represent better performance). The secondary outcome was MIPS payment adjustment, including negative (penalty) payment adjustment, positive payment adjustment, and bonus payment adjustment. Results: The final sample included 636 552 clinicians (41% female, 83% physicians, 50% in primary care, 17% in rural areas), including 48.6% who were affiliated with a health system. Compared with unaffiliated clinicians, system-affiliated clinicians were significantly more likely to be female (46% vs 37%), primary care physicians (36% vs 30%), and classified as safety net clinicians (12% vs 10%) and significantly less likely to be specialists (44% vs 55%) (P < .001 for each). The mean final MIPS performance score for system-affiliated clinicians was 79.0 vs 60.3 for unaffiliated clinicians (absolute mean difference, 18.7 [95% CI, 18.5 to 18.8]). The percentage receiving a negative (penalty) payment adjustment was 2.8% for system-affiliated clinicians vs 13.7% for unaffiliated clinicians (absolute difference, -10.9% [95% CI, -11.0% to -10.7%]), 97.1% vs 82.6%, respectively, for those receiving a positive payment adjustment (absolute difference, 14.5% [95% CI, 14.3% to 14.6%]), and 73.9% vs 55.1% for those receiving a bonus payment adjustment (absolute difference, 18.9% [95% CI, 18.6% to 19.1%]). Conclusions and Relevance: Clinician affiliation with a health system was associated with significantly better 2019 MIPS performance scores. Whether this represents differences in quality of care or other factors requires additional research.

Attitudes of sports organisation members to junk food sponsorship.

OBJECTIVES: To explore sports organisation members' attitudes to sponsorship of sport by energy-dense, nutrient-poor food and drink ('junk food') brands. STUDY DESIGN: The study design is a cross-sectional study. METHODS: An online survey of adult members of three sports organisations that did not accept junk food sponsorship in Victoria, Australia in 2018: one was responsible for an elite team in a national competition (5000-10,000 members); one managed a team sport competition across Victoria (50,000-100,000 registered junior and adult participants, referees and coaches); and one administered a junior team sport competition for boys and girls in a major city (10,000-15,000 participants). RESULTS: Most (71%) of the 2224 respondents reported it was important/very important that their organisation did not accept junk food sponsorship. A higher proportion was concerned/very concerned about junk food companies sponsoring children's sport (60%) compared with such companies sponsoring elite (49%, P < 0.001) or community adult (39%, P < 0.001) sport. A higher proportion of respondents were likely/very likely to support a policy that restricted junk food sponsorship of children's sport (84%), compared with a policy restricting sponsorship of elite (76%, P > 0.001) and adult community (74%, P > 0.001) sport. Two-thirds of respondents supported restricting junk food companies from sponsoring sport, even if fees for children's (66%) and community adult (65%) sport increased, or if membership and attendance costs for elite sport supporters increased (63%). CONCLUSIONS: In the Australian context of this study, junk food sponsorship of sport, particularly children's sport, is a concern to members of sports organisations. Although still high, support for restricting such sponsorship declines if members perceive it will lead to increases in participation costs and decreases in participation opportunities. Initiatives restricting junk food sponsorship of sport are likely to receive strong support from the sports community, particularly when the focus is on children's sport, and participation costs and opportunities are not negatively impacted.

Authors of clinical trials seldom reported details when declaring their individual and institutional financial conflicts of interest: a cross-sectional survey.

BACKGROUND: The main objective of this study was to document details of both individual and institutional financial conflicts of interest (FCOIs) reported by the authors of clinical trials. An additional objective was to assess the predictors of having at least one author reporting any FCOI. METHODS: We used a sample of randomized controlled trials from a previous cross-sectional survey and included the trials, which reported at least one FCOI disclosure. We categorized the types of disclosed FCOI as grant, employment income, personal fees, nonmonetary support, drug or equipment supplies, patent, stocks, and other types. We collected data on the characteristics of the included RCTs, of the authors, and of the reported FCOI disclosures. We conducted descriptive analyses and a regression analysis to assess the predictors of having at least one author reporting any FCOI. RESULTS: All 108 included RCTs reported being funded, with 58% reporting funding by a private-for-profit source. Out of 1,687 authors, 814 (48%) reported at least one, and a median of 2, FCOI disclosures. Of the 814 reporting disclosures, far more reported individual FCOIs (99%) than institutional FCOIs (6%). The most commonly reported individual FCOI subtypes were grant (49%), personal fees (48%), and employment income (22%). Of the 99% of disclosures that included the source of FCOI, a private-for-profit entity provided the funds in 85%. Reporting about the relation of the FCOI source's to the product investigated in the trial, the timing of FCOI, and monetary value of FCOI was limited. Reporting of FCOIs proved most strongly associated with author affiliation being an academic institution (OR = 2.981; 95% CI: 2.415-3.680) and trial funding from entity other than a private-for-profit entity (OR = 2.809; 95% CI: 2.274-3.470). CONCLUSION: Approximately half of the trial authors report individual FCOIs, often three or more, but seldom provide details related to source's relation to the trial, or the timing and monetary value of the FCOI.

Small is beautiful, but large is certified: A comparison between fisheries the Marine Stewardship Council (MSC) features in its promotional materials and MSC-certified fisheries.

The Marine Stewardship Council (MSC) sets a standard by which sustainable fisheries can be assessed and eco-certified. It is one of the oldest and most well-known fisheries certifications, and an estimated 15% of global fish catch is MSC-certified. While the MSC is increasingly recognized by decision-makers as an indicator for fishery success, it is also criticized for weak standards and overly-lenient third-party certifiers. This gap between the standard's reputation and its actual implementation could be a result of how the MSC markets and promotes its brand. Here we classify MSC-certified fisheries by gear type (i.e. active vs. passive) as well as by length of the vessels involved (i.e. large scale vs. small scale; with the division between the two occurring at 12 m in overall length). We compared the MSC-certified fisheries (until 31 December 2017) to 399 photographs the MSC used in promotional materials since 2009. Results show that fisheries involving small-scale vessels and passive gears were disproportionately represented in promotional materials: 64% of promotional photographs were of passive gears, although only 40% of MSC-certified fisheries and 17% of the overall catch were caught by passive gears from 2009-2017. Similarly, 49% of the photographs featured small-scale vessels, although just 20% of MSC-certified fisheries and 7% of the overall MSC-certified catch used small-scale vessels from 2009 to 2017. The MSC disproportionately features photographs of small-scale fisheries although the catch it certifies is overwhelmingly from industrial fisheries.

The Contribution of Physician-System Integrating Structure to Select Health System Outcomes.

Physician groups are increasingly being vertically integrated with hospitals and health systems; yet, the evidence on the impact of physician-system integration on health system outcomes is mixed. The objective of this study was to examine the impact of increased physician-system integration on select health system outcomes. We used a mixed-methods approach: (1) a fixed-effects multivariate mediation analysis; and (2) a qualitative analysis of interviews with health executives (n = 25). Our findings showed that hospitals spent $633 375.22 to $827 110.24 for each "level" increase in integration. This relationship was attenuated, however, by the presence of care coordination mechanisms.

Landscape of Health Systems in the United States.

Despite the prevalence of vertical integration, data and research focused on identifying and describing health systems are sparse. Until recently, we lacked an enumeration of health systems and an understanding of how systems vary by key structural attributes. To fill this gap, the Agency for Healthcare Research and Quality developed the Compendium of U.S. Health Systems, a data resource to support research on comparative health system performance. In this article, we describe the methods used to create the Compendium and present a picture of vertical integration in the United States. We identified 626 health systems in 2016, which accounted for 70% of nonfederal general acute care hospitals. These systems varied by key structural attributes, including size, ownership, and geographic presence. The Compendium can be used to study the characteristics of the U.S. health care system and address policy issues related to provider organizations.

The Role of Organizational Affiliations in Physician Patient-Sharing Relationships.

Provider consolidation may enable improved care coordination, but raises concerns about lack of competition. Physician patient-sharing relationships play a key role in constructing patient care teams, but it is unknown how organization affiliations affect these. We use the Massachusetts All Payer Claims Database to examine whether patient-sharing relationships are associated with sharing a practice site, medical group, and/or physician contracting network. Physicians were 17 percentage points more likely to have a patient-sharing relationship if they shared a practice site and 4 percentage points more likely if they shared a medical group, as compared with sharing no affiliation. However, there was no detectable increased probability of a patient-sharing relationship within the same physician contracting network. Our finding that physician patient-sharing relationships are concentrated within organizational boundaries at practice site and medical group levels helps illuminate referral incentives and provide insight into the role of organizational affiliations in patient care team construction.
