Abstract
PURPOSE Various models of care delivery have been investigated to meet the increasing demands in primary care. One proposed model is comanagement of patients by more than 1 primary care clinician. Comanagement has been investigated in acute care with surgical teams and in outpatient settings with primary care physicians and specialists. Because nurse practitioners are increasingly managing patient care as independent clinicians, our study objective was to propose a model of nurse practitioner–physician comanagement.
METHODS We conducted a literature search using the following key words: comanagement; primary care; nurse practitioner OR advanced practice nurse. From 156 studies, we extracted information about nurse practitioner–physician comanagement antecedents, attributes, and consequences. A systematic review of the findings helped determine effects of nurse practitioner–physician comanagement on patient care. Then, we performed 26 interviews with nurse practitioners and physicians to obtain their perspectives on nurse practitioner–physician comanagement. Results were compiled to create our conceptual nurse practitioner–physician comanagement model.
RESULTS Our model of nurse practitioner–physician comanagement has 3 elements: effective communication; mutual respect and trust; and clinical alignment/shared philosophy of care. Interviews indicated that successful comanagement can alleviate individual workload, prevent burnout, improve patient care quality, and lead to increased patient access to care. Legal and organizational barriers, however, inhibit the ability of nurse practitioners to practice autonomously or with equal care management resources as primary care physicians.
CONCLUSIONS Future research should focus on developing instruments to measure and further assess nurse practitioner–physician comanagement in the primary care practice setting.
INTRODUCTION
With imminent staffing shortages in the health care profession and an increase in the volume of patients seeking primary care services, patient loads are increasing rapidly, thus making it difficult for a single primary care professional to manage all patient care needs effectively and efficiently.1–4 Therefore, policy makers are calling for new primary care delivery models to meet the increased demands for care, especially due to patients with multiple comorbidities requiring more complex primary care visits. Different models of care delivery have been proposed, including team-based care, yet these models often have variability in task allocation and professional roles.5 Identifying innovative models of care delivery is increasingly important to meet these demands in primary care.
One proposed care delivery model includes having more than 1 primary care professional comanaging the same patient and sharing the workload responsibilities or care management tasks. Researchers have explored comanagement of patients by 2 physicians in primary care,6 and by a physician and a nonphysician health care professional, such as a pharmacist.7,8 No model, however, clearly describes the comanagement relationship between physicians and advanced practice nurses, such as nurse practitioners.
Nurse practitioners are registered nurses with advanced master’s or doctoral degrees whose scope of practice usually includes diagnosis and implementation of a patient care plan; regulations regarding the scope of practice vary considerably among the states regarding the need for physician involvement to treat and prescribe.9 Policy makers, and the public, have supported the expansion of nurse practitioners into primary care,10 yet the comanagement relationship between nurse practitioners and physicians remains poorly defined. As more nurse practitioners are designated as primary care clinicians and practice independent of physician oversight, a closer look at what defines successful nurse practitioner–physician comanagement is warranted. The purpose of this article is to present a theoretical model of nurse practitioner–physician comanagement in primary care.
Definition of Comanagement
We define “comanagement” as 2 primary care professionals (a nurse practitioner and a physician) jointly sharing the responsibility of all tasks needed to manage the health care of the same patient. These tasks may include patient visits, such as for acute illness or chronic disease management; pharmacologic management, such as medication refills; diagnostic testing; patient education, in terms of disease prevention or risk reduction; and patient follow-up, such as interpretation of laboratory values and making external patient referrals based on test results. Comanagement also includes sharing the administrative workload related to care coordination, completing paperwork such as disability or employment documents, and responding to patient or caregiver phone calls.
History of Comanagement Model in Health Care
One of the first studies to examine comanagement in health care was a large retrospective cohort study about orthopedic surgery.11 This study examined the effects of a surgeon and primary care physician comanaging the same patient, and results showed positive associations between comanagement and shorter hospital stays and fewer inpatient deaths. Further, comanagement has increasingly become a common practice across acute care organizations, and comanagement agreements have been implemented between surgeons and other health care professionals.12 These agreements clearly lay out responsibilities of each party, communication methods and frequency, and specific guidelines on resolution of disagreements. In the outpatient setting, researchers have focused mainly on comanagement by specialists and primary care physicians, or by pharmacists and physicians.7,13,14 These studies showed that comanagement yields optimal clinical outcomes, such as achieving blood pressure control. No published literature, however, has assessed the effects of nurse practitioner–physician comanagement.
Similar Terms
Terms such as teamwork and collaboration are often used interchangeably with comanagement. “Teamwork,” however, is defined as a group of people working interdependently to achieve a common goal9 and “collaboration” is defined as 2 clinicians consulting with each other and working concurrently by sharing knowledge and expertise to achieve optimal patient care.15 Evidence is clear about the benefits of team-based and collaborative care,16 yet researchers have concluded that evidence is lacking about comanagement approaches to care.17
Team-based care and collaborative care with nurse practitioners often involve a hierarchy with team members aligned in a vertical organizational structure based on profession or role. Vertical hierarchy in an organization influences decision making and subsequently may impede communication or increase mistrust among team members from various professions.18 In contrast, comanagement involves a horizontal organizational structure. Clinicians may comanage across teams in a manner similar to a primary care physician and a cardiologist comanaging the same patient. These 2 physicians work within their own teams within their practices, but overlap horizontally to comanage the same patient. Within the same team, an independent nurse practitioner may comanage the same patient with a physician, in the same practice, based on the urgency or complexity of a patient’s needs. While research has found evidence of the attributes of teamwork, including honesty, discipline, creativity, humility, and curiosity,19 the literature fails to capture the attributes of comanagement between nurse practitioners and physicians.
METHODS
We built our model from the collective findings of 3 studies. First, using Walker and Avant’s method for conceptual analysis,20 we conducted a literature search in 5 electronic databases (Ovid Medline, CINAHL, PubMed, Cochrane Review, and EMBASE) using the following key words: comanagement; primary care; nurse practitioner OR advanced practice nurse. A total of 156 studies were reviewed. We extracted information about nurse practitioner–physician comanagement antecedents, relationships, defining attributes, and consequences. Next, using the PRISMA framework,21 a systematic review was conducted to determine the effects of nurse practitioner–physician comanagement and found an increase in primary care clinician adherence to recommended care guidelines and improved clinical patient outcomes.22 Third, we performed in-person qualitative interviews with nurse practitioners and physicians to obtain their perspectives on nurse practitioner–physician comanagement including the willingness of primary care professionals to comanage care, descriptions of the dimensions of comanagement, and how nurse practitioner–physician comanagement affects patient care. Twenty-six interviews were conducted until data saturation was reached and no new information was emerging from the interviews.22,23 Results of all 3 studies were triangulated to build the conceptual nurse practitioner–physician comanagement model.
Theoretical Underpinnings
Our approach to investigating nurse practitioner–physician comanagement was guided by the theoretical underpinnings of Donabedian’s quality of care model24 (Figure 1). This model provided us with a framework to evaluate the quality of comanagement. Two researchers met weekly to discuss the findings from the 3 studies and extract information about each of the 3 dimensions of quality of care (structure, process, and outcome). First, the researchers obtained information about comanagement structure, which involved the organizational and clinician resources or policies that needed to be in place for nurse practitioners and physicians to comanage the same primary care patient. Next, we evaluated process, that is, how comanagement was being practiced, what interactions were necessary, and the interprofessional relationships between nurse practitioners and physicians. Finally, we evaluated outcomes, which included the results of our systematic review and the reported perspectives of the primary care professionals in our qualitative study.

RESULTS
Antecedents of Nurse Practitioner–Physician Comanagement
The primary antecedent for effective nurse practitioner–physician comanagement is nurse practitioner autonomy. Various policy bodies regulate nurse practitioner scope of practice and nurse practitioner licensure, leading to a wide variablity.9 In addition to national or state-based legislation that defines the nurse practitioner scope of practice, nurse practitioner responsibilities are often determined by organizational policy.25 Despite the adoption of laws that allow nurse practitioners to practice independently of physician oversight, organizational or facility policy may inhibit and restrict a nurse practitioner–physician comanagement model. These restrictions are especially salient in the primary care clinics that adopt a physician-led hierarchical infrastructure in which the physician has the final decision-making authority. In this case, the nurse practitioners do not comanage the patient care but exercise a limited role. Further, organizational climate, and the culture of organizations, heavily influenced by organizational management, often do not identify and/or do not accept nurse practitioners as primary care clinicians.26 In this situation, the organization does not provide the same resources to nurse practitioners as they do physicians.27 These resources include support staff, such as medical assistant help, enough examination rooms for patient visits, involvement on decision-making committees, and availability of learning opportunities.23,28 Our model focused specifically on comanagement in which nurse practitioners and physicians were viewed equally as primary care clinicians, shared equal responsibility for primary care patient management, and were provided with equal resources.
Vital Attributes
Effective nurse practitioner–physician comanagement has 3 vital attributes: (1) effective communication; (2) mutual respect and trust; and (3) clinical alignment, also known as a shared philosophy of care (Figure 2).

Effective Communication
Effective communication is a 2-way process in which primary care professionals send a message that is easily understood by the receiving party to prevent misunderstanding and to save time. Comanagement communication is essential for developing the patient care plan, managing a change in patient health status, individualizing patient goals, and delineating each primary care clinician’s role in the care plan as part of coordinating patient care.29 When the nurse practitioner and physician who are comanaging a patient do not have direct contact with each during their daily activities, the use of secure messaging through an electronic health record (EHR) or telephone calls are the most frequent form of communication.23 Some EHR systems, however, have been found to inhibit communication because the nurse practitioner and physician documentation is located in separate locations within the patient chart, thus preventing them from seeing each other’s notes.23 The setting size and space often influence the type of communication used, with smaller settings using more informal modes of communication, such as text messages.30 Comanagement communication must be performed in a timely manner that is dependent on the patient needs, such as a change in patient acuity level. The communication needs to be reciprocal with equal sharing of ideas, new patient information, and feedback necessary to improve quality of care.31
Mutual Respect and Trust
Respect and trust among nurse practitioners and physicians is the second critical element of comanagement. This attribute increases over time as physicians and nurse practitioners work together longer32; developing reciprocal trust and respect of each other’s role in care delivery can take up to 6 months.30 By gaining trust, physicians are less likely to feel that they need to supervise or “double-check” the work of the nurse practitioner, thereby reducing redundancy of documentation and diagnostic testing.
Traditionally, some physicians view nurse practitioners as having an inferior role in primary care. This viewpoint inhibits nurse practitioners from working to their full potential and can create mistrust or resentment. The physician must have an understanding of the education, training, and scope of practice for nurse practitioners to build trust during allocation of tasks and responsibilities.25 The optimal combination of nurse practitioners’ and physicians’ knowledge, culture, and disciplines has the potential to positively contribute to the quality of patient care.
Shared Philosophy of Care
Physicians and nurse practitioners that we interviewed agreed that each primary care professional must have complementary practice styles that are congruent to mutual goals for patient care, such as a shared philosophy or having a clinical alignment in their patient care plan.31 This shared philosophy includes approaches to care management. Variability of approaches challenges nurse practitioner–physician comanagement. For example, one clinician may opt to treat mental illness in primary care while the other clinician prefers referral to a specialist. Other examples include when to prescribe an antibiotic or when to discontinue a patient-specific treatment, such as pain management.
In the event of disagreement between primary care clinicians regarding care decisions, discussion is vital. However, a mutually agreed-upon protocol for conflict resolution must be in place ahead of time to determine who makes the final care management decision. This protocol may vary by organizational policy or practice setting. Clinical alignment also involves a similar work ethic, such as time management styles. Without a similar work ethic, the workload may become unbalanced and weighted toward 1 of the clinicians, potentially leading to clinician burnout and increased strain. One of the primary care professionals having a higher volume of daily patients than the other clinician may lead to resentment, which may threaten mutual respect and trust or communication, with the potential of indirectly affecting patient care.
Consequences of Comanagement
At the level of the primary care professional, the presence of all 3 attributes of the model leads to clinician cohesion. The stronger comanagement is, the greater the potential for beneficial patient, clinician, and practice outcomes.22 One finding of our interviews was that effective nurse practitioner–physician comanagement alleviated individual clinician workload and the strain to complete all recommended clinical care and administrative tasks single handedly. A reduction of primary care professional workload subsequently prevents clinician strain, burnout, and fatigue, especially with increased patient complexity. Nurse practitioner–physician comanagement also enables interdisciplinary collaboration between nursing and medicine, and better care results from combining the experience and expertise of clinicians from each discipline. Interdisciplinary collaboration also promotes morale among team members and leads to effective and efficient outcomes.33,34
Nurse practitioner–physician comanagement was also found to increase patient access to care and promote continuity of care because patients have 2 clinicians familiar with their history and care needs.29,35 Longevity of patient and primary care professional interactions is often described as a core value of high-quality primary care.36,37 Further, fewer restrictions on the scope of practice for nurse practitioners is associated with an increase in the number of nurse practitioners practicing in rural or medically underserved populations.38 Nurse practitioner–physician comanagement in rural or medically underserved populations allows primary care physicians to free time up for additional appointments, as well as provide patients with more one-on-one time during patient visits to address individual patients’ needs.3
DISCUSSION
More nurse practitioners are practicing as independent primary care professionals, and developing innovative approaches to integrate nurse practitioners and physicians within and across team-based care models is important. This article presents a theoretical model of nurse practitioner–physician comanagement, including the vital attributes of effective communication, mutual respect and trust, and shared philosophy of care.
This novel theoretical understanding has several potential uses. First, use of this model can help create organizational policies needed to ensure the success of nurse practitioner–physician comanagement. When administrators, clinicians, and policy makers promote effective comanagement, individual clinician workload is reduced, thus preventing clinician strain, burnout, and fatigue, especially with increased patient complexity.23 Use of this model also enables increased collaboration among clinicians who discuss and coordinate the complex needs of patients, thereby providing higher quality of care.34,39 Effective nurse practitioner–physician comanagement also has the potential to increase access to care because patients have 2 primary care professionals familiar with their needs and plan of care, thus promoting a continuity of care. If 1 clinician is unavailable, the other can see the patient, preventing a gap in access to care. By sharing the workload, nurse practitioner–physician comanagement can lead to time for additional appointments and/or more one-on-one individualized attention to patient needs. We recommend efforts toward interdisciplinary education within academic institutions so that nurse practitioners and physicians gain knowledge of each other’s disciplines early on and learn strategies to comanage patient care given the complexities of primary care delivery and the identified strengths of each discipline.
Attention to individualized patient care is especially important as reimbursement mechanisms shift from volume-based to value-based care and provider payments are reliant on achieving targeted quality outcomes.40,41 The combination of nurse practitioner and physician expertise in comanagement can help to ensure the highest quality of care. Several studies included in our systematic review demonstrated a significant difference in guideline adherence in favor of nurse practitioners and physicians comanagement of the same patient.22 Furthermore, evidence shows that nurse practitioners in primary care professional roles have equivalent or superior patient outcomes and are potentially cost saving.42 This finding suggests the potential of nurse practitioner–physician comanagement to be more cost effective than 2 physicians comanaging care. More cost-effective studies about nurse practitioner–physician comanagement are warranted.
Lastly, despite the increasing numbers of nurse practitioners and physicians who are already comanaging in practice, a substantial gap in the literature remains about how organizations should design comanagement models. More evidence is needed about which care delivery models are the most efficient and effective in primary care. Nurse practitioner–physician comanagement demonstrates promise to alleviate some of the primary care strain, but more research is needed to produce empirical and generalizable evidence about its impact on clinical, cost, and organizational outcomes. Our theoretical model provides health services researchers with knowledge to operationalize nurse practitioner–physician comanagement in future studies.
A survey instrument is currently being developed from this theoretical model and tested psychometrically to enable measurement of nurse practitioner–physician comanagement in practice and research settings. This survey instrument, once validated, will provide primary care physicians, practice managers, policy makers, and researchers the ability to further investigate nurse practitioner–physician comanagement and its impact on patient or practice outcomes.
The 3 vital attributes from our nurse practitioner–physician comanagement model—effective communication, mutual respect and trust, and a shared philosophy of care—cannot exist without the presence of legal and organizational policies that recognize nurse practitioners as autonomous primary care clinicians. Further, effective nurse practitioner–physician comanagement requires adequate organizational resources and the willingness of nurse practitioners and physicians to comanage. Opposing opinions about the autonomy of nurse practitioners and the drive for physician-led hierarchical infrastructures have prevented autonomous practice of nurse practitioners in primary care.43 As long as such limitations exist, the effective comanagement care model cannot be fully investigated or implemented. We recommend empirical measurement of nurse practitioner–physician comanagement for future research.
