The transition from open to endoscopic saphenous vein harvesting and its clinical impact: The Texas Heart Institute experience.
(33/168)
Open saphenous vein harvesting can be associated with wound complications, incision pain, prolonged convalescence, and poor cosmetic results. Endoscopic vein harvesting has been widely used for prevention of these problems. We compared outcomes of open and endoscopic vein harvesting for coronary artery bypass grafting at the Texas Heart Institute. We retrospectively analyzed data from 1,573 consecutive coronary artery bypass procedures performed at our institution during a 20-month period. Each procedure included saphenectomy by endoscopic vein harvesting (n = 588) performed by physician assistants, or by traditional open vein harvesting (n = 985) performed by physicians or physician assistants. The primary outcome variable was the incidence of postoperative leg infections. Both groups were similar in terms of preoperative risk factors. After surgery, leg wound infections were significantly less frequent in the endoscopic vein harvesting group (3/588, 0.5%) than in the open vein harvesting group (27/985, 2.7%; P < 0.002). The most common organism involved in leg infections was Staphylococcus (20/30, 66%): S. aureus was present in 14 of 30 infections (47%). Open vein harvesting was the only significant independent risk factor for leg infection. We conclude that endoscopic vein harvesting reduces leg wound infections, is safe and reliable, and should be the standard of care when venous conduits are required for coronary artery bypass grafting and vascular procedures. Although the transition from open to endoscopic vein harvesting can be challenging in institutions, it can be successful if operators receive adequate training in endoscopic technique and are supported by surgeons and staff.

Nonphysician clinicians in the neonatal intensive care unit: meeting the needs of our smallest patients.
(34/168)
Regional variations in the distribution of neonatal physicians and dependence on housestaff with restricted work hours have created workforce shortages in many NICUs. Although neonatal nurse practitioners assist in the delivery of high-quality care, availability of these providers may be inadequate in certain regions. Physician assistants represent a historically underutilized resource to resolve neonatology's workforce issues. We have developed a postgraduate training program for physician assistants in neonatology that we hope will improve local and regional workforce shortages. In this article we discuss the history of neonatal nurse practitioners and physician assistants in newborn care and outline the program that we developed. We further discuss some of the barriers we had to overcome in developing this program. Our program can serve as a model for other neonatology programs to adequately prepare physician assistants for a career in the NICU. (+info)
What do clinicians want? Interest in integrative health services at a North Carolina academic medical center.
(35/168)
BACKGROUND: Use of complementary medicine is common, consumer driven and usually outpatient focused. We wished to determine interest among the medical staff at a North Carolina academic medical center in integrating diverse therapies and services into comprehensive care. METHODS: We conducted a cross sectional on-line survey of physicians, nurse practitioners and physician assistants at a tertiary care medical center in 2006. The survey contained questions on referrals and recommendations in the past year and interest in therapies or services if they were to be provided at the medical center in the future. RESULTS: Responses were received from 173 clinicians in 26 different departments, programs and centers. There was strong interest in offering several specific therapies: therapeutic exercise (77%), expert consultation about herbs and dietary supplements (69%), and massage (66%); there was even stronger interest in offering comprehensive treatment programs such as multidisciplinary pain management (84%), comprehensive nutritional assessment and advice (84%), obesity/healthy lifestyle promotion (80%), fit for life (exercise and lifestyle program, 76%), diabetes healthy lifestyle promotion (73%); and comprehensive psychological services for stress management, including hypnosis and biofeedback (73%). CONCLUSION: There is strong interest among medical staff at an academic health center in comprehensive, integrated services for pain, obesity, and diabetes and in specific services in fitness, nutrition and stress management. Future studies will need to assess the cost-effectiveness of such services, as well as their financial sustainability and impact on patient satisfaction, health and quality of life. (+info)
A new paradigm of cardiovascular risk factor modification.
(36/168)
Atherosclerotic cardiovascular diseases (CVDs) are the leading cause of death and disability in the United States. While multiple studies have demonstrated that modification of atherosclerotic cardiovascular risk factors (CVRFs) significantly reduces morbidity and mortality rates, clinical control of CVDs and CVRFs remains poor. By 2010, the American Heart Association seeks to reduce coronary heart disease, stroke, and risk by 25%. To meet this goal, clinical practitioners must establish new treatment paradigms for CVDs and CVRFs. This paper discusses one such treatment model--a comprehensive atherosclerosis program run by physician extenders (under physician supervision), which incorporates evidence-based CVD and CVRF interventions to achieve treatment goals.

Nurse practitioner and physician assistant interest in prescribing buprenorphine.
(37/168)
Office-based buprenorphine places health care providers in a unique position to combine HIV and drug treatment in the primary care setting. However, federal legislation restricts nurse practitioners (NPs) and physician assistants (PAs) from prescribing buprenorphine, which may limit its potential for uptake and inhibit the role of these nonphysician providers in delivering drug addiction treatment to patients with HIV. This study aimed to examine the level of interest in prescribing buprenorphine among nonphysician providers. We anonymously surveyed providers attending HIV educational conferences in six large U.S. cities about their interest in prescribing buprenorphine. Overall, 48.6% (n = 92) of nonphysician providers were interested in prescribing buprenorphine. Compared to infectious disease specialists, nonphysician providers (adjusted odds ratio [AOR] = 2.89, 95% confidence interval [CI] = 1.22-6.83) and generalist physicians (AOR = 2.04, 95% CI = 1.09-3.84) were significantly more likely to be interested in prescribing buprenorphine. NPs and PAs are interested in prescribing buprenorphine. To improve uptake of buprenorphine in HIV settings, the implications of permitting nonphysician providers to prescribe buprenorphine should be further explored. (+info)
Missing in action: care by physician assistants and nurse practitioners in national health surveys.
(38/168)
OBJECTIVE: To assess applicability of national health survey data for generalizable research on outpatient care by physician assistants (PAs) and nurse practitioners (NPs). DATA SOURCES: Methodology descriptions and 2003 data files from the National Ambulatory Medical Care Survey, the National Hospital Ambulatory Medical Care Survey, the Medical Expenditure Panel Survey, and the Community Tracking Study. STUDY DESIGN: Surveys were assessed for utility for research on PA and NP patient care, with respect to survey coverage, structure, content, generalizability to the U.S. population, and validity. National estimates of patient encounters, statistically adjusted for survey design and nonresponse, were compared across surveys. DATA COLLECTION/EXTRACTION METHODS: Surveys were identified through literature review, selected according to inclusion criteria, and analyzed based on methodology descriptions. Quantitative analyses used publicly available data downloaded from survey websites. PRINCIPAL FINDINGS: Surveys varied with respect to applicability to PA and NP care. Features limiting applicability included (1) sampling schemes that inconsistently capture nonphysician practice, (2) inaccurate identification of provider type, and (3) data structure that does not support analysis of team practice. CONCLUSIONS: Researchers using national health care surveys to analyze PA and NP patient interactions should account for design features that may differentially affect nonphysician data. Workforce research that includes NPs and PAs is needed for national planning efforts, and this research will require improved survey methodologies. (+info)
A physician extender training program based on clinical algorithms.
(39/168)
The ability of physician extenders to provide patient care in a variety of settings has been reported widely. Less attention has been paid to training programs, especially those of short duration, for physician extenders. A three-month training program for physician extenders at a large teaching hospital was based on teaching the skills needed to run 39 clinical algorithms. The course content and the methods used to test the students during the three months may prove of value to those preparing similar programs. (+info)
