Four databases (Medline, ProQuest, Embase, and CINAHL) were researched using the keywords “interprofessional education”, “interprofessional practice”, “collaborative practice”, “health policy”, “health law”, and “health regulation”. After the removal of duplicates, 200 abstracts were analyzed to ensure that the articles focused on policy and law. Only 34 articles dealt with the impact of policy or regulations and were retained for closer analysis. An additional 30 published items relevant to the review were found in the references. After this analysis, additional legal database research on the relevant jurisdictions’ legal environments was conducted to provide textual examples of IPECP policies or regulations.
The goal is to allow readers to reflect on their corresponding IPECP systems and identify legal or policy barriers and facilitators that can be enhanced or modified to foster IPECP. When possible, examples are provided. To ensure a common understanding of terminology, an international glossary is also provided in Additional file 1: Appendix 1.
The education sector is involved in interprofessional education (IPE) from the beginning of the prelicensure curriculum to the completion of the education program, when the learner enters the labor market. The impact of higher education on the achievement of healthcare innovation and desired outcomes, especially in a flexible healthcare workforce, should not be overlooked [18,19,20].
Higher education organizational structure
At the level of the higher education system, IPECP requires coordination and adaptability. A common higher education system in which each health caregiver receives and completes his or her education within a similar structure facilitates IPE promotion and implementation [21, 22]. The establishment of centralized control over the higher education process could facilitate IPE implementation by focusing the agenda on one stakeholder and emphasizing a more uniform philosophy/perception of IPECP [23, 24]. The strongest expression of centralized governmental IPE promotion would be a Ministry of Education mandate (in the form of a decree or regulation) to integrate IPE into government-approved curricula for health professionals.
An excellent example is the Danish Ministry of Education mandates on IPE. In Denmark, the government has mandated that occupational therapy, physiotherapy and nursing curricula must introduce, in practice and theory, elements of IPE . The mandate does not specify the elements of accreditation per se, but programs must obey the decree to be recognized as valid by the governmental body. While there is no research specifically on the link between this policy and IPECP, there is evidence of strong collaborative patient-centered care in stroke rehabilitation driven by IP-ready professionals .
Although the issue of funding is beyond the scope of this article, the impact of recurrent financial support for IPE in higher education, especially when it is part of an IPE regulation or policy, should be recognized [27, 28].
Higher education accreditation structure
The accreditation process is a powerful instrument for implementing IPE and is usually profession-specific since the process is often linked to a regulatory body’s recognition of a program [29, 30]. A central accreditation structure can facilitate standardization if IPE/IPC is specifically introduced in accreditation criteria [23, 30,31,32,33]. Most health teaching institutions want their curricula and diplomas to be recognized as leading to licensure (a legal qualification) by the licensing body. If accreditation is required for this type of legal recognition, the presence of IPE within accreditation standards is a good foundation for IPE implementation. A regulatory body or government might choose, for the sake of worldwide recognition, to issue a policy recommendation (not an obligation) that institutions become accredited either through an international organization or a local organization using international standards. In this context, the licensing authority can still recognize all programs, even in the absence of accreditation, but professional mobility is then linked to accreditation, which can provide a strong incentive for IPE .
Higher education accreditation content
In the context of a robust accreditation system, a specific standard for IPE, regardless of the wording, underlines the importance of IPECP and has the potential to ensure consistency in the healthcare profession .
Two examples illustrate the IPE accreditation process. Canada’s Accreditation for IPE in Healthcare (AIPHE) project resulted in the integration of IPE language into the accreditation standards of more than 8 health professions in Canada. Starting in 2010, federal professional accreditors, with the participation of provincial colleges for each profession, mandated that IPE be an element of professional education across Canada . A similar model is also present in Australia [30, 35]. These two models of profession-specific IPE accreditation standards display important diversity in both the wording and actionability of the IPE-associated standards. As underlined by a study conducted in the USA, heterogeneity in IPE accreditation standards led to a patchwork of IPC-ready professionals in the workforce but did not necessarily contribute to fostering IPC as a whole in the system . Studies are currently underway to evaluate the impact of the Canadian and Australian cross-country IPE accreditation mandates.
Although IPE should always be present as a part of continuous professional development, the focus in the labor market is on how caregivers practice and what regulatory and legal context they practice in. Therefore, literature is on IPC more than IPE.
For labor market IPC, two aspects need to be discussed since they impact IPC in different ways: healthcare facilities and health profession policies and laws. Both aspects are macro-level aspects of the labor market, but they are often dependent on different governmental bodies or ministries. Although funding is a macro-level aspect and can impact IPC, it is beyond the scope of this article [1, 36,37,38].
Health professional system regulation and internal structure
Health professionals work in an environment that is legally governed by multiple different texts. How professions are regulated is a key aspect of professional practice. Umbrella laws, which are legal tools that regulate multiple professions under a single statute or act, are recognized as conducive to IPC [6, 7, 11, 39, 40]. Moreover, a common legal structure promotes a culture of equality among professions . It also facilitates changes in professional structures, which is an important aspect of IPC [11,12,13, 41].
Another key aspect of professional regulation is the notion of the scope of practice, which represents the area of competence. Descriptive and adaptable scopes of practice are conducive to effective IPC because they allow health professionals to practice to the full extent of their competence without legally infringing on another profession’s scope of practice [11, 12].
Finally, an administrative structure is necessary to enforce a regulation. The existence of a global regulatory body with compulsory power (an organization with a code of ethics that regulates professional practice) can facilitate evaluation of IPC practices and the application of IPC professional obligations [28, 31, 40, 42,43,44,45,46,47].
There are multiple examples of umbrella laws across the world . Structural statutes that ensure a certain uniformity within the regulation of health professions are popular [30, 35, 44, 48]. There are actually three forms of umbrella laws: the first two are top-down, with legislators giving mandates. The two models both use the descriptive scope of practice approach: the first is specific to the health and social care professions, as in Ontario, Canada , or Australia , and the second is global for all professions regardless of the activity sector, as in Quebec, Canada . The latter form is bottom up: the umbrella law has the objective of fostering cooperation or collaboration among colleges, with individual statutes for every regulated profession, as in Nova Scotia, Canada [39, 50].
Since the Quebec model is the oldest in existence, there is the most evidence about its impact on IPC [51, 52], with numerous joint practice standards or guidelines from two or more professional colleges published in French on the website www.collaborationinterprofessionnelle.ca.
Healthcare continuum and healthcare facility accessibility
Care often occurs on a continuum. This continuum of care is anchored in structural law and policy governing whom the patient can see, where he or she can go, and who decides when and how he or she enters or leaves the premises of a healthcare institution. Often overseen by policymakers, health professional-specific control over the care continuum can favor a hidden hierarchy in IPC teams, hindering IPC efficiency [4, 36, 53,54,55,56].
There are numerous projects related to IPC and the care continuum [28, 57]. One example of the integration of IPC into care management regulations is Finland’s healthcare system. Structured around a dual-financing model of (Beveridge-type) municipal tax funding and (Bismarck-type) mandated insurance contributions, municipalities have a public mandate to organize the care continuums within their jurisdictions. This legal mandate is established by a Finnish governmental statute, the Health Care Act #1326/2010, under the Ministry of Social Affairs and Health. This 2010 statute specifically mandates that municipalities include multidisciplinary health provider teams on operating conditions (Section 4), home nursing (Section 25) and primary healthcare units (Section 35), the three main branches of the care continuum. Since 2019, these mandates have fallen under the jurisdiction of 18 newly created healthcare and welfare counties. The main disadvantages of such a primary healthcare unit system mandate are patients’ limited choice of providers  and the highly decentralized nature of the healthcare system, making IPC implementation difficult to study [58, 59].
Health professional and civil liability or torts
Although often analyzed separately, liability, or torts, is a central part of the health professional regulatory environment . Independent liability can both facilitate and hinder IPC depending on the legal relationships between professions. Complete autonomy, uniform liability insurance for all and a common legal understanding are facilitators of IPC [6, 7, 60,61,62]. When these conditions are met, a centralized no-fault system can further mitigate the impact of liability on IPC, as seen in different countries around the globe [63, 64].
As an example, New Zealand’s no-fault compensation healthcare system was implemented in 1974. It was initially not part of the medical liability agenda but rather a result of a labor-related policy effort . Since then, there have been multiple changes and additions. Putting aside the fault-driven legalistic compensation process, the New Zealand legislature chose an out-of-court approach to compensating for each “treatment injury” (articles 32 to 34 of the Accident Compensation Act 2001), regardless of the registered health providers concerned. If an injury sustained by a patient is not a normal result of the treatment or a result of an underlying disease, a structured approach to compensation is applied. Injury evaluations, compensation and claims management are performed by a public entity, namely, the Accident Compensation Corporation, which is funded by multiple public and private entities (part 7 of the Accident Compensation Act 2001). This model has the potential to limit the impact of protective behaviors on IPC.
Healthcare facility internal policy for professional labor
Healthcare providers act according to their locally applied policies. How these local policies are determined impacts how IPC is promoted or implemented. Thus, the commonality of professional–institutional relationships (common labor and organizational rules) in a given facility paves the way for the existence of an IPC team [14, 36, 65, 66]. Knowledge of policy content and the legal environment is key to professional engagement in IPC-promoting policy changes .
An example of the importance of professional engagement in policy application is the Western Cape Department of Health (WCDOH), which has an explicit policy on the importance of IPC in ensuring patient-centered care. However, this policy does not seem to have had the intended consequences. The literature seems to indicate that this policy is not embodied in the actual care model and has not broken the health profession’s hierarchical culture . This example underlines the importance of clinicians’ understanding of policy content and clinicians’ knowledge of regulations and the scope of practice to ensure the success of internal policy implementation.
