ObjectiveTo estimate the relationship between outcomes of care and medical practices' structure and use of organized care improvement processes.Data sources/study settingWe linked Medicare claims data to our national survey of physician practices (2012-2013). Fifty percent response rate; 1,040 responding practices; 31,888 physicians; 868,213 attributed Medicare beneficiaries.Study designCross-sectional observational analysis of the relationship between practice characteristics and total spending, readmissions, and ambulatory care-sensitive admissions (ACSAs), for all beneficiaries and five categories of beneficiary defined by predicted need for care.Principal findingsPractices with 100+ physicians and 50-99 physicians had, respectively, annual spending per high-need beneficiary that was $1,870 (12.5 percent) and $1,824 higher than practices with 1-2 physicians, and readmission rates 1.64 and 1.71 higher. ACSA rates did not vary significantly by practice size. Outcomes did not vary significantly by ownership or by practices' use of organized processes to improve care.ConclusionsLarge practices had higher spending and readmission rates than the smallest practices, especially for high-need beneficiaries. There were no significant performance differences between physician-owned and hospital-owned practices. Policy makers should consider the effects of specific policies on provider organization, pending further research to learn which types of practice provide better care.

ObjectiveTo examine the relationship of physician versus hospital ownership of small- and medium-sized practices with spending and utilization of care.Data source/study setting/data collectionSurvey data for 1,045 primary care-based practices of 1-19 physicians linked to Medicare claims data for 2008 for 282,372 beneficiaries attributed to the 3,010 physicians in these practices.Study designWe used generalized linear models to estimate the associations between practice characteristics and outcomes (emergency department visits, index admissions, readmissions, and spending).Principal findingsBeneficiaries linked to hospital-owned practices had 7.3 percent more emergency department visits and 6.4 percent higher total spending compared to beneficiaries linked to physician-owned practices.ConclusionsPhysician practices are increasingly being purchased by hospitals. This may result in higher total spending on care.

PurposeImplementation and meaningful use of health information technology (HIT) has been shown to facilitate delivery system transformation, yet implementation is far from universal. This study examined correlates of greater HIT implementation over time among a national cohort of small primary care practices in the United States.MethodsWe used data from a 40-minute telephone panel survey of 566 small primary care practices having 8 or fewer physicians to investigate adoption and use of HIT in 2007-2010 and 2012-2013. We used generalized estimating equations (GEE) to estimate the association of practice characteristics and external incentives with the adoption and use of HIT. We studied 18 measures of HIT functionalities, including record keeping, clinical decision support, patient communication, and health information exchange with hospitals and pharmacies.ResultsOverall, use of 16 HIT functionalities increased significantly over time, whereas use of 2 decreased significantly. On average, compared with physician-owned practices, hospital-owned practices used 1.48 (95% CI, 1.07-1.88; P

ObjectivesReports suggest a trend for physician practices to change ownership from physicians to hospitals. It remains unclear how this change affects quality of patient care. We report the effect of a change to hospital ownership on the use of care management processes (CMPs) and health information technology (IT) among practices in the United States.Study designTrend analyses of 3 large national surveys of physician practices.MethodsWe included 2 cohorts of practices: large practices with 20 or more physicians and small/medium practices with fewer than 20 physicians. The main outcomes were the changes in CMP and health IT indices among practices that were acquired by hospitals. We used multivariate logistic regression to assess these changes.ResultsLarge practices acquired by hospitals had larger increases in their CMP index than those that remained physician-owned (11.0-point increase vs 7.0-point decrease; adjusted P = .03). Small/medium practices acquired by hospitals had smaller but significantly higher increases in their CMP score (3.8 points vs 2.6 points; adjusted P = .04). Among all practices, there were no significant differences in the change of the health IT index.ConclusionsWe found a significant increase in the use of CMPs among practices that were acquired by hospitals and no difference in health IT use. These findings suggest that a trend for hospitals to own physician practices may have a positive effect on chronic disease management and quality of care.

BackgroundDatabases of practicing physicians are important for studies that require sampling physicians or counting the physician population in a given area. However, little is known about how the three main sampling frames differ from each other.ObjectiveOur purpose was to compare the National Provider and Plan Enumeration System (NPPES), the American Medical Association Masterfile and the SK&A physician file.MethodsWe randomly sampled 3000 physicians from the NPPES (500 in six specialties). We conducted two- and three-way comparisons across three databases to determine the extent to which they matched on address and specialty. In addition, we randomly selected 1200 physicians (200 per specialty) for telephone verification.Key resultsOne thousand, six hundred and fifty-five physicians (55 %) were found in all three data files. The SK&A data file had the highest rate of missing physicians when compared to the NPPES, and varied by specialty (50 % in radiology vs. 28 % in cardiology). NPPES and SK&A had the highest rates of matching mailing address information, while the AMA Masterfile had low rates compared with the NPPES. We were able to confirm 65 % of physicians' address information by phone. The NPPES and SK&A had similar rates of correct address information in phone verification (72-94 % and 79-92 %, respectively, across specialties), while the AMA Masterfile had significantly lower rates of correct address information across all specialties (32-54 % across specialties).ConclusionsNone of the data files in this study were perfect; the fact that we were unable to reach one-third of our telephone verification sample is troubling. However, the study offers some encouragement for researchers conducting physician surveys. The NPPES and to a lesser extent, the SK&A file, appear to provide reasonably accurate, up-to-date address information for physicians billing public and provider insurers.

BackgroundThe accountable care organization (ACO) is a new organizational form to manage patients across the continuum of care. There are numerous questions about how ACOs should be optimally structured, including compensation arrangements with primary care physicians.MethodsUsing data from a national survey of physician practices, we compared primary care physicians' compensation between practices in ACOs and practices that varied in their financial risk for primary care costs using 3 groups: practices not participating in a Medicare ACO and with no substantial risk for primary care costs; practices not participating in an ACO but with substantial risk for primary care costs; and practices participating in an ACO regardless of their risk for primary care costs. We measured physicians' compensation as the percentage of compensation based on salary, productivity, clinical quality or patient experience, and other factors. Regression models estimated physician compensation as a function of ACO participation and risk for primary care costs while controlling for other practice characteristics.ResultsPhysicians in ACO and non-ACO practices with no substantial risk for costs on average received nearly one-half of their compensation from salary, slightly less from productivity, and about 5% from quality and other factors. Physicians not in ACOs but with substantial risk for primary care costs received two-thirds of their compensation from salary, nearly one-third from productivity, and slightly more than 1% from quality and other factors. Participation in ACOs was associated with significantly higher physician compensation for quality; however, participation was not significantly associated with compensation from salary, whereas financial risk was associated with much greater compensation from salary.ConclusionAlthough practices in ACOs provide higher compensation for quality, compared with practices at large, they provide a similar mix of compensation based on productivity and salary. Incentives for ACOs may not be sufficiently strong to encourage practices to change physician compensation policies for better patient experience, improved population health, and lower per capita costs.

ObjectiveTo provide the first nationally based information on physician practice involvement in ACOs.Data sources/study settingPrimary data from the third National Survey of Physician Organizations (January 2012-May 2013).Study designWe conducted a 40-minute phone survey in a sample of physician practices. A nationally representative sample of practices was surveyed in order to provide estimates of organizational characteristics, care management processes, ACO participation, and related variables for four major chronic illnesses.Data collection/extraction methodsWe evaluated the associations between ACO participation, organizational characteristics, and a 25-point index of patient-centered medical home processes.Principal findingsWe found that 23.7 percent of physician practices (n = 280) reported joining an ACO; 15.7 percent (n = 186) were planning to become involved within the next 12 months and 60.6 percent (n = 717) reported no involvement and no plans to become involved. Larger practices, those receiving patients from an IPA and/or PHO, those that were physician-owned versus hospital/health system-owned, those located in New England, and those with greater patient-centered medical home (PCMH) care management processes were more likely to have joined an ACO.ConclusionsPhysician practices that are currently participating in ACOs appear to be relatively large, or to be members of an IPA or PHO, are less likely to be hospital-owned and are more likely to use more care management processes than nonparticipating practices.

ObjectiveWe sought to determine the extent to which adoption of health information technology (HIT) by physician practices may differ from the extent of use by individual physicians, and to examine factors associated with adoption and use.Materials and methodsUsing cross-sectional survey data from the National Study of Small and Medium-Sized Physician Practices (July 2007-March 2009), we examined the extent to which organizational capabilities and external incentives were associated with the adoption of five key HIT functionalities by physician practices and with use of those functionalities by individual physicians.ResultsThe rate of physician practices adopting any of the five HIT functionalities was 34.1%. When practices adopted HIT functionalities, on average, about one in seven physicians did not use those functionalities. One physician in five did not use prompts and reminders following adoption by their practice. After controlling for other factors, both adoption of HIT by practices and use of HIT by individual physicians were higher in primary care practices and larger practices. Practices reporting an emphasis on patient-centered management were not more likely than others to adopt, but their physicians were more likely to use HIT.DiscussionLarger practices were most likely to have adopted HIT, but other factors, including specialty mix and self-reported patient-centered management, had a stronger influence on the use of HIT once adopted.ConclusionsAdoption of HIT by practices does not mean that physicians will use the HIT.

ObjectiveTo examine the relationship between practices' reported use of patient-centered medical home (PCMH) processes and patients' perceptions of their care experience.Data sourcePrimary survey data from 393 physician practices and 1,304 patients receiving care in those practices.Study designThis is an observational, cross-sectional study. Using standard ordinary least-squares and a sample selection model, we estimated the association between patients' care experience and the use of PCMH processes in the practices where they receive care.Data collectionWe linked data from a nationally representative survey of individuals with chronic disease and two nationally representative surveys of physician practices.Principal findingsWe found that practices' use of PCMH processes was not associated with patient experience after controlling for sample selection as well as practice and patient characteristics.ConclusionsIn our study, which was large, but somewhat limited in its measures of the PCMH and of patient experience, we found no association between PCMH processes and patient experience. The continued accumulation of evidence related to the possibilities of the PCMH, how PCMH is measured, and how the impact of PCMH is gauged provides important information for health care decision makers.

This paper measures the extent to which medical groups experience external pay-for-performance incentives based on quality and patient satisfaction and the extent to which these groups pay their primary care and specialist physicians using similar criteria. Over half (52%) of large medical groups received bonus payments from health insurance plans in the period 2006-2007 based on measures of quality and patient satisfaction. Medical groups facing external pay-for-performance incentives are more likely to pay their primary care physicians (odds ratio [OR] 4.5; p

Objective. To describe the proportion, characteristics, and attitudes of pediatricians who want to allocate more time in primary care to children with special health care needs (CSHCN). Methods. Data from a national random sample mail survey of 1000 pediatricians were used to examine attitudes towards allocating more time to CSHCN, and associated preferences towards changes to primary care. Results. Sixty percent (n=502) of eligible subjects participated. Forty-five percent of pediatricians reported that, if they could redesign their practices to maximize efficiency and effectiveness, they would allocate more time to providing care to CSHCN. After multivariate adjustment, respondents who wanted to allocate more time to CSHCN were more likely to want to allocate more time to care coordination with staff (OR 3.6[1.7-7.4, p≤0.001]) and non-visit communication with parents (OR 3.0[1.7-5.5], p≤0.001), and were more likely to prefer delegation of well-child care services to non-physicians (OR 5.9[2.8-12.5], p≤0.001). Inadequate reimbursement was reported as the most important obstacle to implementing such changes in their practices. Conclusions. These findings suggest that a substantial number of pediatricians would ideally allocate more time in primary care to CSHCN. Systems of care that could support such a change should be investigated.

Organized care management processes (CMPs) can improve health care quality for patients with chronic diseases. The Institute of Medicine of the National Academy of Sciences has called for public and private purchasers of health care to create incentives for physician organizations (POs) to use CMPs and for the government to assist POs in implementing information technology (IT) to facilitate CMP use. Research is lacking about the extent to which POs use CMPs or about the degree to which incentives, IT, or other factors are associated with their use.To determine the extent to which POs with 20 or more physicians use CMPs and to identify key factors associated with CMP use for 4 chronic diseases (asthma, congestive heart failure, depression, and diabetes).One thousand five hundred eighty-seven US POs (medical groups and independent practice associations) with 20 or more physicians were identified using 5 large databases. One thousand one hundred four of these POs (70%) agreed to participate in a telephone survey conducted between September 2000 and September 2001. Sixty-four responding POs were excluded because they did not treat any of the 4 diseases, leaving 1040 POs.Extent of use of CMPs as calculated on the basis of a summary measure, a PO care management index (POCMI; range, 0-6) and factors associated with CMP use.Physician organizations' mean use of CMPs was 5.1 of a possible 16; 50% used 4 or fewer. External incentives and clinical IT were most strongly associated with CMP use. Controlling for other factors, use of the 2 most strongly associated incentives-public recognition and better contracts for health care quality-was associated with use of 1.3 and 0.7 additional CMPs, respectively (P
