Size matters – Alternatives to vertical integration

Alternatives to hospital dominated, vertically integrated systems.

For decades, pundits have predicted the demise of solo and small practices, and health care systems have been pushing policies that hasten their demise. And yet, small practices persist.

A study by Liaw et al, finds that most family physicians seeking board certification are in small and solo practices. Small practices constitute the largest category of practice size among physicians providing care in rural areas, and small or solo practice is more common among African American, Hispanic, and more experienced physicians. Medical home status and having a care coordinator are more common as practice size increases.

This research shows that amidst the rush toward increasing scale, which requires complicated, explicit, and often klunky systems, it may be important to not devalue smaller, local levels of scale in which simple, personal, often implicit systems may function well and meet the particular needs of both practitioners and disadvantaged populations.

An editorial by Mostashari highlights the potentially vital role for small practices in a rapidly changing health care system. In another editorial, Glancey and Kennedy share an on-the-ground view of quality and payment from the perspective of an idealized micro practice.

The opposite end of the size spectrum is revealed in a study by Casalino and colleagues, who identified and studied large, independent primary care medical groups. The size of these groups presents an opportunity for economies of scale, but what makes these practices particularly interesting is the combination of size and physician ownership. This gives them power to not only organize primary care, but to be an effective patient-focused force in organizing care and in selectively engaging narrowly focused care that is often both high risk and high cost. Large systems run by hospitals have very different incentives and perspectives.

A population-based study by Dahrouge examines the association of family physicians’ panel sizes with quality of care and health service use. The complex findings are worthy of thoughtful interpretation. Among small practices, greater panel size is associated with slightly lower cancer screening and comprehensiveness of care, little difference in chronic disease management quality, greater hospitalization rates for ambulatory care-sensitive conditions, and lower rates of non-urgent emergency department visits. Continuity of care is highest with medium panel sizes. Clearly, practice panel size has complex effects, or at least correlates, that depend on local context and other factors.

What both small and very large independent practices have in common is an on-the-ground focus on the whole person. Their presence is a threat to the hegemony of hospital-dominated systems. Such systems can use their power to vertically integrate care, but are conflicted in providing patient-centered care when they compete over providing high-risk, high-cost care commodities, and are paid more to perform procedures than to focus holistically on patient needs. Even with more value-based payment, large hospital-dominated systems require very complex systems in order to perform the integrating, personalizing, prioritizing functions that are efficiently and effectively performed by primary care.

Before it is too late to diversify the headlong rush toward a monoculture of vertically integrated, hospital-dominated systems, it is worth broadening the ideology and ecology of reform to test the hypothesis that higher-value personalization, integration, and sustainability may be provided by horizontally integrated systems based on independent large and small primary care practices that are well linked with mental health care and public health, and that selectively purchase vertical integration from hospitals and specialists.

Technology supporting patients, clinicians, and communication

In a nationally representative sample, Serrano and colleagues identify a gradient of patients’ willingness to exchange different kinds of information using mobile devices, and the characteristics of patients willing to engage in different kinds of electronic health information interchange. This is useful information for designing and implementing electronic information systems to meet the needs of different types of patients.

High-risk groups

Among 3 durations of opioid use, Scherrer et al find that longer duration of use is associated with new onset of depression, whereas shorter durations (and dose) are not associated with incident depression. Another interesting incidence study finds a high rate of new depressive symptoms in a consecutive sample of adult patients presenting for care in primary care practices in a Hong Kong practice-based research network. The rate of incident depression is lower among patients seen by physicians with qualifications in both family medicine and psychological medicine, implying the possibility of a preventive benefit of seeing clinicians with joint training. Asgary and colleagues find a very high rate of uncontrolled hypertension among adults using homeless shelters. Interestingly, those with multiple chronic conditions have better hypertension control, as do those with insurance.

New methods for assessing home blood pressure and for studying diverse groups

Until now, clinicians have not had an empirically validated method for assessing a patient’s home blood pressure beyond informally looking over a list of home blood pressure readings. The study by Sharman et al, featured in Annals Journal Club, finds that the percentage of the last 10 home systolic blood pressures ≥135 mm HG provides a reasonable estimate of the reference standard of 24-hour ambulatory blood pressure. In the research realm, Fetters et al develop a novel split-session method for conducting focus groups, in which time is divided between sessions with the entire group and with subgroups. The researchers find this method useful in a specific application to studying physicians and staff members in primary care practices.

Reflections from experience

The Paradox of Size: How Small, Independent Practices Can Thrive in Value-Based Care.

Farzad Mostashari MD, Annals of Family Medicine January/February 2016

The arguments for consolidation are well known: ease of coordinated care, less duplication of tests and treatment, and decreased costs due in part to economies of scale. Under a consolidation philosophy, provider organizations evolve from solo physician practices; to groups and multispecialty practices; and finally, to fully integrated delivery systems that employ the physicians, own the hospitals, and use a single information system (and sometimes even play the role of health insurance plan).

In this Darwinian view of health care delivery, “lower” forms of practice organization are assumed to be incapable of implementing the supporting systems needed for population health (eg, registries, electronic medical records, care management, and team-based care) and are therefore unable to compete in value-based payment systems.

Yet, small independent primary care practices are not unevolved primates; evidence instead suggests they are uniquely situated to thrive in delivering value-based care. From 2004 to 2011 hospital ownership of physician practices increased from 24% of practices to 49%. This consolidation does not appear to have resulted in lower prices, higher quality, or better care experiences.

Instead, hospital ownership of a doctor’s group dramatically increases the probability that patients go to hospitals that employ their doctor, even when those hospitals are lower quality and higher cost. The main effect of such consolidation is not true clinical integration, but market power used to extract higher prices from payers and to prevent any efficiencies from being passed on to payers and consumers.

Meanwhile, recent evidence suggests that small, physician-owned practices, while providing a greater level of personalization and responsiveness to patient needs, have lower average cost per patient, fewer preventable hospital admissions,7 and lower readmission rates than larger, independent- and hospital-owned practices.
