Physician Perceptions of Advanced Practice Providers on Hospitalist Teams

Little is known about physician perceptions of nurse practitioners (NPs) and physician assistants (PAs) on hospitalist teams and the factors that impact their perceptions. Academic physician hospitalists were surveyed to better understand those factors, focusing on NP/PA experience, training, and physician experience with NPs/PAs. Perceptions by hospitalist physicians of NPs/PAs were strongly positive. Notable findings include the perceived positive impacts of NPs/PAs on clinical care provided, practice efficiency, and physician satisfaction. Most respondents prefer working with NPs and PAs with multiple years of clinical experience, particularly those who have participated in training beyond NP/PA graduate programs of study.     

Nurse practitioner and physician assistant satellite health centers. The pending demise of an organizational form?

A national cohort of 44 rural satellite health centers originally staffed by nurse practitioners (NPs) and physician assistants (PAs) was studied in 1975 and resurveyed in 1979 and in 1984 to examine the viability of this type of health-care delivery organization during a period of significant growth in the nation's physician supply. Twelve of these practices had ceased to function, although eight have been replaced by physician practices. Of the remaining 32, 14 have physicians on their staffs and 18 remain staffed only by NPs and PAs. Those centers staffed by physicians experience greater patient utilization, charge more for office visits, have larger budgets, and generate more of their budgets from fees for services and therefore appear to be more organizationally stable than centers staffed only by NPs and PAs. Although broader studies are needed for substantiation, these findings suggest that the period when NP/PA-staffed satellite health centers were important organizations for delivering care to previously underserved rural communities may be ending.     

Impact of state scope-of-practice laws on nurse practitioner-provided home visits

Millions of older Americans receive nurse practitioner (NP)-provided home based primary care (HBPC). Little is known about how state scope-of- practice (SOP) laws may impact use of NP-home visits. Using 2017 Centers for Medicare and Medicaid Services Provider Utilization and Payment Data Public Use File (PUF), we examined the impact of state SOP laws on the use of NP-home visits. The PUF file was merged with the 2017 American Community Survey to assess area-level median income. Over 4.4 million home visits were provided to 1.6 million Medicare beneficiaries. NPs represented the largest share of providers (47.5%). In states with restricted SOP laws, compared to NPs, physicians and physician assistants had higher odds of providing HBPC. In states with reduced SOP laws, compared to NPs, physicians and PAs had decreased odds of providing HBPC. Our study provides evidence that SOP restrictions are associated with decreased utilization of NP-provided HBPC.     

Use of midlevel providers in US EDs, 1993 to 2005: implications for the workforce

Objective

The aim of the study was to evaluate use of physician assistants (PAs) and nurse practitioners (NPs) in US emergency departments (EDs).

Methods

We analyzed visits from the 1993 to 2005 National Hospital Ambulatory Medical Care Survey, seen by midlevel provider (MLP), and compared characteristics of MLP visits to those seen by physicians only.

Results

From 1993 to 2005, 5.2% (95% CI, 4.6%-5.8%) of US ED visits were seen by PAs and 1.7% (95% CI, 1.5%-2.0%) by NPs. During the study period, PA visits rose from 2.9% to 9.1%, whereas NP visits rose from 1.1% to 3.8% (both P_trend < .001). Compared to physician only visits, those seen only by MLPs arrived by ambulance less frequently (6.0% vs 15%), had lower urgent acuity (37% vs 59%), and were admitted less often (3.0% vs 13%).

Conclusions

Midlevel provider use has increased in US EDs. Their involvement in some urgent visits and those requiring admission suggests that the role of MLPs extends beyond minor presentations.     

Assessing the utilization and productivity of nurse practitioners and physician's assistants: methodology and findings on productivity

This article describes the research design, survey instrument and methodology employed in a national study to assess the utilization and productivity of nurse practitioners and physician assistants (NP/PAs) in primary care settings. All practices (N = 455) used in the study employed formally trained NP/PAs who treated, or were eligible to treate, Medicare patients on an outpatient basis, and included a general practitioner, family practitioner or a general internist as the supervising physician. A matched group of comparison practices were subject to the same eligibility criteria except that they did not employ NP/PAs. A comprehensive diary-type instrument focusing on patient care was used to collect detailed data on each practitioner's daly professional activities. Data are presented on the productivity of NPs, PAs and physicians as measured by seven basic variables related to patient volume, time in patient care and revenue generated. Numerous inter- and intraspecialty comparisons were made across various practice arrangements and across location variables such as rural vs. urban, remote vs. nonremote, and health care resource areas. Interpretations of the data indicate clearly that PAs are considerably more productive than NPs. However, although NPs spend more time with individual patients, the cause of this differential productivity was not revealed.     

Strategies to Overcome Barriers to Effective Nurse Practitioner and Physician Collaboration

Nurse practitioners (NPs) and physicians have worked together to manage patients since the inception of the NP role in the 1960s.¹ Because the underserved and rural areas lacked primary and specialty care physicians, the NP role eventually evolved to one of a collaborating midlevel provider.² The integrated use of NPs and physicians together has positively affected the health care system, yet barriers to effective collaboration continue to exist, and this may lead to a reduced level of quality health care for patients. The barriers to effective collaboration between NPs and physicians are important to consider because the main goals of any NP–physician collaborative team are positive patient care outcomes.     

Differences in the number of services provided by nurse practitioners and physicians during primary care visits

BackgroundDue to differential training, nurse practitioners (NPs) and physicians may provide different quantities of services to patients.PurposeTo assess differences in the number of laboratory, imagining, and procedural services provided by primary care NPs and physicians.MethodsSecondary analysis of 2012–2016 National Ambulatory Medical Care Survey (NAMCS), containing 308 NP-only and 73,099 physician-only patient visits, using multivariable regression and propensity score techniques.FindingsOn average, primary care visits with NPs versus physicians were associated with 0.521 fewer laboratory (95% CI −0.849, −0.192), and 0.078 fewer imaging services (95% CI −0.103,−0.052). Visits for routine and preventive care with NPs versus physicians were associated with 1.345 fewer laboratory (95% CI −2.037,−0.654), and 0.086 fewer imaging services (95% CI −0.118,−0.054) on average. Primary care visits for new problems with NPs versus physicians were associated with 0.051 fewer imaging services (95% CI −0.094,−0.007) on average.DiscussionNPs provide fewer laboratory and imaging services than physicians during primary care visits.     

Nurse practitioners and physician assistants in emergency medical services who billed independently, 2012–2016

Objective

As nurse practitioners (NPs) and physician assistants (PAs) become an integral part of delivering emergency medical services, we examined the involvement of NPs and PAs who billed independently in emergency departments (EDs).

Characteristics of patient visits to nurse practitioners in hospital outpatient departments.

Nurse practitioners (NPs) are the largest and the fastest growing groups among nonphysician practitioners in the United States. However, there has been lack of studies on the supply, demand, and use of nurse practitioners in hospital outpatient departments (OPDs) across the nation. Using the National Hospital Ambulatory Medical Care Survey (1997-2000), this study describes patient visits to NPs in general medicine, pediatrics, and obstetrics/gynecology clinics in hospitals across the nation. The percentage of patient visits involving NPs increased from 5.9 percent in 1997 to 7.3 percent in 2000. NPs have greater roles in hospital OPDs in nonmetropolitan areas than in metropolitan areas. Regional difference in patient visits to NPs supports the relationship between the practice environment and the use of NPs. As expected, NPs continue to serve the health care needs of women and children in hospital OPDs. Of all OPD visits with a NP service, NPs saw patients with no presence of a physician in 82 percent of these visits. As the role of the NP evolves in the U.S. health care delivery system, further studies on the clinical practice of NPs in hospital OPDs can help evaluate the impact of NPs in providing quality of patient care at minimum cost.     

Physician assistants in primary care. Patient assignment and task delegation

This paper reports a concurrent self-report study of 2,456 office encounters with physicians and/or physician assistants (PAs) in 16 primary care, private practices in Florida. Initial patient assignment to either a physician or PA varies according to demographic and visit-specific characteristics. Patients who are male, younger than 65 years, new patients, seeking help for acute problems, and those who are "walk-in" or "work-in" patients are more likely to be assigned to a PA. Among frequently performed procedures, physicians are more likely to perform the partial histories, partial physicals, and pelvic examinations, as well as counsel patients on diet and psychosocial problems. PAs are more likely to perform the complete physical examinations, record vital signs, conduct diagnostic tests, and perform therapeutic procedures (administer injections, change dressings, etc.). Most tasks performed by PAs receive supervision through chart review rather than direct oversight. The typical patient visit in a practice employing a PA involves the receipt of services from only one provider. Approximately 50% of patient services are performed by physicians only, while 35% of the services are performed solely by PAs, and 15% are performed by both. Most patients have received care from both the physician and the PA.     

A comparison of the National Ambulatory Medical Care Survey (NAMCS) measurement approach with direct observation of outpatient visits

BACKGROUND: The National Ambulatory Medical Care Survey (NAMCS) informs a wide range of important policy and clinical decisions by providing nationally representative data about outpatient practice. However, the validity of the NAMCS methods has not been compared with a reference standard. METHODS: Office visits of 549 patients visiting 30 family physicians in Northeastern Ohio were observed by trained research nurses. Visit content measured by direct observation was compared with data reported by physicians using the 1993 NAMCS form. RESULTS: Outpatient visit physician reports of procedures and examinations using the NAMCS method showed generally good concordance with direct observation measures, with kappas ranging from 0.39 for ordering a chest x-ray to 0.86 for performance of Pap smears. Concordance was generally lower for health behavior counseling, with kappas ranging from 0.21 for alcohol counseling to 0.60 for smoking cessation advice. The NAMCS form had high specificity (range, 0.90-0.99) but variable (range, 0.12-.84) sensitivity compared with direct observation, with the lowest sensitivities for health behavior counseling. The NAMCS physician report method overestimated visit duration in comparison with direct observation (16.5 vs. 12.8 minutes). CONCLUSIONS: Compared with direct observation of outpatient visits, the NAMCS physician report method is more accurate for procedures and examinations than for health behavior counseling. Underreporting of behavioral counseling and overreporting of visit duration should lead to caution in interpreting findings based on these variables.     

Factors associated with the use of advanced practice nurses/physician assistants in a fee-for-service nursing home practice: a comparison with primary care physicians

The purpose of this research was to examine factors associated with the use of advanced practice nurse and physician assistant (APN/PA) visits to nursing home (NH) patients compared with those by primary care physicians (PCPs). This was a secondary analysis using Medicare claims data. General estimation equations were used to determine the odds of NH residents receiving APN/PA visits. Ordinary least squares analyses were used to examine factors associated with these visits. A total of 5,436 APN/PAs provided care to 27% of 129,812 residents and were responsible for 16% of the 1.1 million Medicare NH fee-for-service visits in 2004. APN/PAs made an average of 33 visits annually compared with PCPs (21 visits). Neuropsychiatric and acute diagnoses and patients with a long-stay status were associated with more APN/PA visits. APN/PAs provide a substantial amount of care, but regional variations occur, and Medicare regulations constrain the ability of APN/PAs to substitute for physician visits.
