Clinical practice characteristics of osteopathic and allopathic primary care physicians at academic health centers: results from the National Ambulatory Medical Care Survey.

PURPOSE: To explore characteristics of patient visits to osteopathic physicians (DOs) and allopathic physicians (MDs) in the provision of ambulatory primary care services at academic health centers (AHCs) relative to non-AHC sites. METHOD: Physicians report patient visits to the National Ambulatory Medical Care Survey (NAMCS). The authors used NAMCS data (2002-2006) to statistically estimate, characterize, and compare patient visits of four physician provider type- and AHC site-specific subgroups: DOs and MDs at non-AHC sites, and DOs and MDs at AHC sites. RESULTS: The 134,369 patient visits reported in the NAMCS database represented 4.57 billion physician office visits after the authors applied patient weights. These visits included 2.03 billion primary care patient visits (205.1 million DO visits and 1.77 billion MD visits at non-AHC sites; 5.8 million DO visits and 52.3 million MD visits at AHC sites). Practicing at an AHC site appeared to change the dynamic of the patient visit to an osteopathic physician. Most notably, these changes involved patient demographics (sex), patient visit context (practice metropolitan statistical area status, patient symptom chronicity, and injury as reason for the visit), and medical management (diagnostic testing, frequency and intensity of ordering drugs, and use of osteopathic manipulative treatment). CONCLUSIONS: Evidence suggests that osteopathic physicians in community, non-AHC settings offer a more distinctive osteopathic approach to primary care than osteopathic physicians at AHC sites, which both indicates a need for further research to explain this phenomenon and has potentially important implications for osteopathic medical education.

Research funding at colleges of osteopathic medicine: 15 years of growth.

CONTEXT: Colleges of osteopathic medicine (COMs) trying to stimulate research and develop research infrastructures must overcome the challenge of obtaining adequate funding to support growing research interests. The authors examine changes in research funding at COMs during the past 15 years. OBJECTIVES: To track 1999-2004 data on COM research funding, COM faculty size, educational backgrounds of principal investigators receiving funding, and funding institutions. To compare these data with published results from 1989 to 1999. METHODS: Data on number of grants, funding amounts by extramural source, percent of total dollars by extramural source, percent of total dollars by COM, and total amount of extramural funding were obtained from the American Association of Colleges of Osteopathic Medicine databases. Data on the Osteopathic Research Center (ORC) were obtained from the ORC's databases. RESULTS: Research, both in terms of number of grants and funding amounts within the osteopathic medical profession, increased substantially from 1999 to 2004. The largest single source of funding remained the National Institutes of Health. The number of COMs whose research funding exceeded $1 million annually more than doubled, increasing from 5 in 1999 to 12 in 2004. The osteopathic medical profession's decision to direct research dollars into a national research center devoted to research specific to osteopathic manipulative medicine resulted in an almost eightfold return on initial investment in 4 years. CONCLUSIONS: The amount of research productivity at a COM may be aligned with the size of the COM's full-time faculty, suggesting that once "critical mass" for teaching, service, and administration are achieved, a productive research program can be realized. Expanding the evidence base for those aspects of medicine unique to the osteopathic medical profession is dependent on the future growth of research.

Hemodynamic effects of osteopathic manipulative treatment immediately after coronary artery bypass graft surgery.

CONTEXT: Coronary artery bypass graft (CABG) surgery is a common procedure for patients with coronary artery disease. The physiologic effects of postoperative osteopathic manipulative treatment (OMT) following CABG have not been documented previously. OBJECTIVE: To determine the effects of OMT on cardiac hemodynamics post-CABG surgery. DESIGN: Pilot prospective clinical study (N=29). SETTING AND PATIENTS: Treatment subjects (n=10) undergoing CABG surgery were recruited for postoperative OMT. The primary assessment compared, pre-OMT versus post-OMT, measurements of thoracic impedance, mixed venous oxygen saturation (SvO2), and cardiac index. Records of control subjects (n=19) who underwent CABG surgery--but who did not receive OMT--were assessed for SvO2 and cardiac index at 1 hour and 2 hours postsurgery. INTERVENTION: Immediately following CABG surgery (< or = 2 h), OMT was provided to subjects to alleviate anatomic dysfunction of the rib cage caused by median sternotomy and to improve respiratory function. This adjunctive treatment occurred while subjects were completely anesthetized. RESULTS: A post-OMT increase in thoracic impedance (P < or = .02) in OMT subjects demonstrated that central blood volume was reduced after OMT, suggesting an improved peripheral circulation. Mixed venous oxygen saturation also increased (P < or = .005) after OMT. These increases were accompanied by an improvement in cardiac index (P < or = .01). Comparisons of postoperative measurements in OMT subjects versus those in control subjects revealed statistically significant differences for SvO2 (P < or = .005) and cardiac index (P < or = .02) between the two groups. CONCLUSION: The observed changes in cardiac function and perfusion indicated that OMT had a beneficial effect on the recovery of patients after CABG surgery. The authors conclude that OMT has immediate, beneficial hemodynamic effects after CABG surgery when administered while the patient is sedated and pharmacologically paralyzed.

The national cholesterol education program adult treatment panel ill guidelines.

Coronary heart disease (CHD) remains the leading cause of death in the United States with more than 40% of all deaths each year directly attributed to the disease. Current evidence suggests that early identification and aggressive modification of risk factors offer the most promising approach to reducing the burden of CHD. Dyslipidemia has been identified as the primary risk factor leading to the development of CHD. It is estimated that nearly 65 million Americans require some form of lipid-modification therapy. The National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) set of guidelines released in May 2001 provides physicians with evidence-based recommendations on the classification, diagnosis, and treatment of lipid disorders. New features of the guidelines include a scoring system for calculating CHD risk, as well as the identification of CHD risk equivalents, lower treatment target goals, and an emphasis on conditions conferring a higher risk for CHD, such as the metabolic syndrome. The ATP III emphasis on risk assessment substantially increases the number of patients considered at risk for CHD and will expand the number eligible for lifestyle and drug interventions. This article highlights the new recommendations and reviews the impact of ATP III on osteopathic physicians.

Underidentification and undertreatment of dyslipidemia.

Despite increased attention placed on the identification and treatment of dyslipidemia, this condition remains undiagnosed and untreated in a significant number of patients. The recently released National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) set of cholesterol management guidelines increases to more than 65 million the number of Americans eligible for lipid-modifying therapy. Recent data, however, suggest that even with the availability of multiple regimens with proven efficacy, as many as 50% of all patients do not have their cholesterol assessed and less than 45% receive lipid-modifying therapy. In addition, less than 25% of patients are treated to their NCEP target low-density lipoprotein cholesterol (LDL-C) level. Persistence with therapy is another challenge, as more than 70% of patients fail to maintain their therapy beyond 12 months. If a realistic attempt is to be made to reduce the risk of coronary heart disease (CHD) among Americans, diagnosis of dyslipidemia and treatment to therapeutic targets must be improved. This artide discusses the underdiagnosis and undertreatment of lipid disorders and reviews the role of osteopathic physicians in strategies achieving ATP III LDL-C goals.
