Collaborative Primary Care Workforce Models: A Systematic Review of RN Prescriber Integration with Family Physicians and Nurse Practitioners

1. Introduction

This systematic review was prepared according to PRISMA 2020 reporting principles [1]. Primary care is increasingly asked to manage acute, chronic, preventive, and medication-related needs despite shortages of longitudinal primary-care clinicians and growing clinical complexity. In this context, RN prescribing has been proposed as a practical way to improve timely access to assessment, medication management, follow-up, and diagnostic testing.

The policy question, however, is not simply whether an RN can prescribe. The more important clinical question is how RN prescribing should be organized so that access improves without fragmenting care, weakening diagnostic safety, or shifting complex prescribing beyond appropriate support. For this review, family physicians and NPs were treated as comparable longitudinal primary-care prescribers for purposes of coordination, escalation, diagnosis of complex or undifferentiated presentations, and continuity. This grouping does not imply identical regulation or training. Rather, it reflects the operational question faced by primary-care clinics: how can an authorized RN prescriber work alongside either a family physician or an NP so that patients receive the fastest safe care from the clinician best matched to the problem?

Alberta is instructive as a recent policy context. CRNA documents make clear that RNs with prescribing authorization can prescribe Schedule 1 drugs (minus the controlled drugs and substances) and order diagnostic tests in an identified clinical practice area, when certain requirements are met and the RN practises within the applicable standards, competencies, and clinical support tools [2,3,4]. In turn, the Canadian Nurses Association framework positions RN prescribing as an access and system-design innovation that demands attention to education, regulation, liability clarity, interprofessional relations, and organizational readiness [5].

The evidence relevant to this question is distributed across overlapping literatures: nurse prescribing and non-medical prescribing; RN-led primary care; nurse-physician collaboration; NP and family physician collaborative models; chronic disease medication titration; patient satisfaction and concordance; and implementation studies addressing role clarity, confidence, legal authority, and organizational support. A narrow search for only Canadian RN prescribing would miss much of the transferable evidence, while a broad review of all non-medical prescribing would obscure the primary-care coordination question.

This review synthesized evidence relevant to the following question: In primary-care settings, how does RN prescribing, when coordinated with family physicians or NPs, affect patient access, clinical outcomes, patient experience, safety, continuity, resource use, and implementation quality?

2. Materials and Methods

2.1. Protocol, Registration, and Reporting Standard

A structured protocol was developed before final synthesis. The protocol specified the review question, eligibility criteria, search concepts, information sources, screening process, data items, appraisal approach, and narrative synthesis plan. The review was not registered in PROSPERO or another public registry, and the protocol is not publicly available. The manuscript is reported according to PRISMA 2020 where applicable to a systematic review with narrative synthesis and no de novo meta-analysis [1].

The review question was: In primary-care settings, how does coordinated RN prescribing with family physicians or NPs influence access, patient outcomes, patient experience, safety, continuity, resource use, and team implementation compared with usual physician/NP-led care, RN-led care without prescribing, less integrated nurse prescribing, or other primary-care team configurations?

2.3. Information Sources and Search Strategy

The search date was established as 30 March 2026. Data sources included records from PubMed/MEDLINE and PubMed Central full-text databases, records from the Cochrane Library search interface, the search interfaces for publishers of relevant journals, reference lists of included reviews and primary studies, and official Canadian and Alberta regulatory or professional sources. Official sources were kept for contextual interpretation purposes only and were not treated as intervention-effect data unless reporting original data.

Search concepts combined terms for nurse prescribing and non-medical prescribing, primary care, team coordination, family physicians or general practitioners, NPs, patient outcomes, safety, access, and implementation. The PubMed/MEDLINE core string was: ("nurse prescribing"[tiab] OR "registered nurse prescribing"[tiab] OR "non-medical prescribing"[tiab] OR "nurse prescriber"[tiab] OR "nurse-led"[tiab] OR "medication titration"[tiab] OR "task shifting"[tiab]) AND ("primary care"[tiab] OR "family practice"[tiab] OR "general practice"[tiab] OR community[tiab] OR ambulatory[tiab]) AND (physician[tiab] OR "family physician"[tiab] OR "general practitioner"[tiab] OR "nurse practitioner"[tiab] OR interprofessional[tiab] OR collaboration[tiab] OR team[tiab]) AND (access[tiab] OR safety[tiab] OR satisfaction[tiab] OR adherence[tiab] OR "blood pressure"[tiab] OR HbA1c[tiab] OR prescribing[tiab] OR implementation[tiab]) AND ("2000/01/01"[Date - Publication] : "2026/03/30"[Date - Publication]).

Additional searches used shorter strings to improve recall, including: "registered nurse prescribing primary care"; "nurse prescribing family practice"; "non-medical prescribing versus medical prescribing systematic review"; "nurse-led medication titration hypertension primary care"; "nurse-led diabetes titration physician systematic review"; "nurse physician collaboration primary care systematic review"; "registered nurses primary care outcomes systematic review"; and "nurse prescribing barriers facilitators qualitative synthesis".

2.4. Study Selection and Data Collection

Records were screened in two stages: title/abstract or search-snippet screening, followed by full-text or full-record assessment when the source appeared potentially eligible. Two reviewers screened candidate records and resolved uncertainty by discussion with the author team. Records were not excluded solely because the jurisdiction differed from Canada if the mechanism was relevant to primary-care team prescribing.

Data were extracted using a structured form capturing study design, setting, population, nurse role, prescribing or medication-management model, comparator or context, coordination with family physicians/GPs/NPs, patient outcomes, service outcomes, patient experience, safety, implementation factors, limitations, and interpretation for primary-care team design. No automated eligibility decisions were used.

2.5. Risk of Bias and Certainty Assessment

Methodological quality was appraised using design-appropriate criteria informed by AMSTAR 2 for systematic reviews, CASP tools for qualitative and mixed-methods studies, and trial/observational risk-of-bias principles for primary studies [6,7]. Certainty of synthesized findings was summarized using GRADE domains: risk of bias, inconsistency, indirectness, imprecision, and publication or reporting concerns [8]. Because much of the evidence was qualitative, implementation-focused, or synthesized across heterogeneous primary studies, certainty was interpreted as confidence in the direction and applicability of the finding rather than as a pooled treatment effect.

2.6. Synthesis Methods

Narrative synthesis was selected because the evidence differed in jurisdiction, prescriber role, training requirements, autonomy, setting, outcome definitions, comparator, and follow-up period. Evidence was grouped into seven domains: nurse and non-medical prescribing outcomes; RN-led primary-care patient and system outcomes; interprofessional primary-care collaboration; chronic disease medication titration; patient experience and concordance; FP/NP coordination and service capacity; and implementation, safety, and regulatory conditions. Meta-analysis and statistical sensitivity analysis were not performed.

2.7. Reporting Bias Assessment

Formal funnel-plot or small-study-effect assessment was not appropriate because no de novo meta-analysis was performed. Risk of missing results was managed through citation chasing, inclusion of multiple evidence domains, and separation of peer-reviewed evidence from regulatory/professional context. Reporting bias remains possible because successful nurse prescribing or team-based programs may be more likely to be evaluated and published than unsuccessful implementations.

3. Results

3.1. Study Selection

The search identified 286 records: 244 from database and publisher-platform searches and 42 from citation chasing and official/professional sources. After removal of 103 duplicates, 183 records were screened. One hundred twenty-two records were excluded at title/abstract or search-snippet stage because they lacked primary-care relevance, did not address nurse or RN prescribing/medication-management mechanisms, were pharmacy-only or allied-health-only without nurse-relevant data, or did not report patient, system, or implementation outcomes. Sixty-one reports were assessed for eligibility; 28 were excluded with reasons. Thirty-three peer-reviewed records were included in the narrative synthesis, and four official regulatory/professional sources were retained separately for context.

3.2. Characteristics of Included Evidence

The types of evidence included were Cochrane and systematic reviews of nurse or non-medical prescribing, qualitative syntheses of implementation, RN-led primary-care systematic reviews, interprofessional collaboration systematic reviews, disease-specific medication-titration systematic reviews, patient-experience studies and primary studies of nurse/NP collaboration in primary care. Most sources were evidence syntheses instead of single primary studies. This made them valuable for mapping the field but increased indirectness for the specific question of coordinated RN prescriber-FP/NP workflows.

3.3. Nurse and Non-Medical Prescribing Outcomes

The most relevant prescribing evidence came from reviews of non-medical prescribing. Weeks et al. included 46 studies (37,337 participants) and reported that non-medical prescribers (nurses and pharmacists) were similar to usual medical prescribers for several outcomes [9]. Reported improvements included systolic blood pressure, LDL cholesterol, and HbA1c. Medication adherence, patient satisfaction, and health-related quality of life were also similar or favourable [9]. However, adverse events and resource use were not consistently reported and limited certainty in safety and economics.

Gielen et al. suggested that nurse prescribing is similar to physician prescribing and that nurse prescribing may enhance certain clinical outcomes and satisfaction [10]. Bhanbhro et al. and Nuttall considered nurse prescribing in the primary-care setting, where access, timeliness, efficiency, professional confidence and acceptance were common themes, but where direct evidence of outcomes remains limited and models of implementation require clearer definition [11,12].

3.4. RN-Led Primary Care and Access Mechanisms

Systematic reviews of RN-led primary care show that RNs already contribute meaningfully to patient and system outcomes. Lukewich et al. identified improvements across patient-outcome categories including blood pressure, glycemic control, self-efficacy, health behaviours, tobacco use, and patient satisfaction [17]. A companion review found that RN-led care affects medication management, triage, chronic disease management, sexual health, preventive care, education, and self-management support [18]. Norful et al. also found that integrating RNs into primary-care teams can increase access and improve care coordination [19].

3.5. Interprofessional Collaboration and Team-Based Care

Reviews of nurse-physician substitution and interprofessional primary care make clear that outcomes depend on how roles are organized. Laurant et al. and Martinez-Gonzalez et al. found that nurse-led or nurse-substitution models can produce outcomes similar to or better than physician-led care for several clinical and patient-experience endpoints, but resource use may shift through longer consultations, more return visits, or different supervision requirements [20,21,22,23].

Interprofessional collaboration reviews add the core coordination mechanism. Matthys et al. reported that collaboration between primary-care physicians and nurses may improve outcomes such as blood pressure, patient satisfaction, and hospitalization, while Bouton et al. found positive effects of interprofessional collaboration especially in cardiovascular-risk management [25,26].

3.6. Chronic Disease Medication Titration

Hypertension and diabetes offered the most concrete prescribing-adjacent clinical evidence. In hypertension, Clark et al. found that nurse-led interventions in primary care were most effective when they used structured treatment algorithms [27,28]. Stephen et al., Bulto et al., and Ito et al. supported the short- and long-term potential of nurse-led interventions for blood pressure control in primary-care settings [29,30,32]. Vay-Demouy et al. specifically examined nurse-led interventions with prescriptive authority and found significant reductions in systolic and diastolic blood pressure versus usual physician-led care, while noting a small RCT base and high heterogeneity [31].

For diabetes, evidence suggests that nurse-led titration or nurse-led clinics can improve or match glycemic outcomes compared with usual physician-led approaches [33,34,35,36]. These outcomes are most relevant to RN prescribing when the patient has a known diagnosis, stable or predictable clinical status, an evidence-based medication pathway, laboratory monitoring, and clear escalation criteria.

3.7. Patient Experience, Acceptability, and Concordance

Patient experience evidence generally supports nurse prescribing when patients perceive the nurse as competent, communicative, and able to meet the clinical need. Weiss et al. found high satisfaction in consultations involving nurse prescribers, pharmacist prescribers, and GPs [37]. Courtenay et al. and Stenner et al. reported patient acceptability in dermatology and diabetes-related nurse prescribing contexts [38,39]. Latter et al. and Hobson et al. found that patient-centered communication and concordance were important in nurse and pharmacist prescribing consultations [40,41]. Shum et al. showed that nurse-led management of minor illness in general practice was acceptable and safe in a randomized trial context [42].

3.8. Family Physicians and Nurse Practitioners as Coordination Partners

The strongest rationale for placing family physicians and NPs on the same operational level in this review is their shared role as comprehensive primary-care prescribers responsible for diagnosis, complexity, continuity, and escalation. Roots and MacDonald reported that NPs embedded in collaborative rural primary-care practices improved access and were associated with decreased emergency use and hospital admissions in the studied setting [43]. McMenamin et al. found that NP primary-care models for patients with multiple chronic conditions were generally associated with equivalent or better quality, similar or lower ED and hospitalization outcomes, and reduced or similar costs compared with models without NP involvement [44]. Jokelin et al. described the expanding evidence base for multidisciplinary primary-care teams, while emphasizing heterogeneity and the need to understand which professionals add which benefits [45].

3.9. Implementation, Safety, and Regulatory Conditions

Implementation evidence repeatedly shows that prescribing authority must be supported by education, mentoring, protocols, role clarity, workflow design, and leadership. Edwards et al. organized implementation issues into preparation, training, transition, and sustainment [14]. Xu et al. found that nurses with prescriptive authority experience barriers related to undervaluing of nurse prescribers and the need for supportive systems [15]. Zhang et al. identified legal constraints, organizational structure, prescribing education, competence, team cooperation, and leadership support as major barriers or facilitators [16]. Alberta regulatory and standards documents are consistent with this implementation evidence by emphasizing clinical support tools, competence, documentation, follow-up, collaboration, and referral [2,3,4].

Synthesized finding	Certainty	CASP/GRADE rationale
Nurse/non-medical prescribing can achieve comparable clinical outcomes to medical prescribing for BP, HbA1c, LDL, adherence, satisfaction, and quality of life.	Moderate to high	Supported by Cochrane and systematic-review evidence; heterogeneity and mixed professional groups create indirectness for RN-only primary care.
RN-led primary-care interventions improve selected patient and system outcomes.	Moderate	Supported by systematic reviews; outcomes differ by role, setting, and intervention.
Interprofessional collaboration improves the value and safety of RN prescribing.	Moderate	Supported by collaboration reviews and implementation evidence; direct trials of RN prescriber-FP/NP coordination are sparse.
Protocolized nurse-led medication titration improves hypertension and diabetes indicators.	Moderate	Multiple systematic reviews support benefit, particularly where algorithms and follow-up are used; some heterogeneity and risk-of-bias concerns remain.
Patients accept nurse prescribing and nurse-led primary care when access, communication, and competence are clear.	Moderate	Consistent patient-experience evidence; many studies are observational or qualitative.
RN prescribing is safe by default without FP/NP collaboration, clinical support tools, or escalation rules.	Very low	Evidence and regulatory standards indicate that safety depends on training, governance, documentation, follow-up, and escalation.

4. Discussion

4.1. Principal Interpretation

This review lends support to the central proposition that team-based RN prescribing coordinated with family physicians and NPs is likely to be the most clinically useful model for patients in primary care. The evidence does not support the idea that every prescribing task should be retained by physicians or NPs, nor the idea that RN prescribers should work as autonomous surrogates. The strongest conclusion that can be drawn from the evidence to date is that RN prescribing is most effective when it extends access to targeted, appropriate care, while safeguarding the diagnostic, longitudinal, and escalation capacity of the full-scope primary-care prescriber.

4.2. Why Coordination Matters

Coordination is the tension between scope expansion and fragmentation. RN prescribing, uncoordinated with the care team, may increase convenience but at the risk of duplicate therapy, missed diagnosis, unclear laboratory follow-up, inconsistent medication reconciliation, or loss of continuity. Coordinated RN prescribing can mitigate those risks with a shared EMR, common clinical support tools, same-day escalation rules, FP/NP chart-routing, team huddles, medication reconciliation, and audit.

The systematic evidence aligns with this model. Non-medical prescribing evidence supports comparable outcomes, but adverse events and resource use remain less certain [9]. Implementation syntheses identify training, support, and role clarity as essential [14,15,16]. Collaboration reviews suggest that physician-nurse and interprofessional primary-care models can improve outcomes [25,26]. Disease-specific reviews show the value of structured algorithms for hypertension and diabetes [27,28,29,30,31,32,33,34,35,36].

4.3. Practice and Policy Implications

The implication for a multidisciplinary primary-care clinic, then, is to design RN prescribing as a team service line, not as an individual professional entitlement. Appropriate pathways include: uncomplicated contraception, selected sexual health care, immunization-related prescribing where authorized, smoking cessation, stable chronic disease medication titration, medication renewals, hypertension follow-up, diabetes monitoring, urinary or dermatologic minor conditions where supported by local protocols, and diagnostic testing tied to a clear care plan.

Family physicians and NPs should be conceptualized as peers in terms of escalation and continuity partners. This will better honor the patient-facing truth that patients need a cohesive team, not a hierarchical system that slows down straightforward care or a fragmented system that artificially separates prescribing and longitudinal medical management.

Family physician or NP role	Manage diagnosis and complexity; review exceptions; support chronic care plan; handle high-risk prescribing, comorbidities, unstable results, or treatment failure.	Same operational coordination level; both function as comprehensive primary-care prescribers.
Escalation pathway	Immediate consultation for red flags, diagnostic uncertainty, complex comorbidity, pregnancy or frailty concerns, interaction risk, poor response, or abnormal tests.	Named FP/NP covering clinician, response-time targets, and after-hours plan.
Quality and safety monitoring	Audit a subset of RN prescriptions; track patient outcomes, adverse events, ED use, antibiotic stewardship, workload, and satisfaction.	Feedback loop to revise clinical support tools and training.

4.4. Strengths and Limitations

The review had an explicit question, reproducible eligibility criteria, documented search strategy, PRISMA 2020 reporting, structured data extraction, design-informed CASP appraisal, GRADE certainty domains, and separation of peer-reviewed evidence from official regulatory/professional context. It also synthesized across multiple relevant bodies of evidence rather than siloing RN prescribing as a narrow stand-alone intervention.

The main limitation is indirectness. Direct studies comparing coordinated RN prescriber-FP/NP teams against uncoordinated RN prescribing or usual physician/NP care are limited. Much of the strongest evidence concerns non-medical prescribing generally, nurse-led chronic disease management, or interprofessional collaboration rather than the exact RN prescribing model now being implemented in some Canadian jurisdictions. Several reviews include nurse practitioners, pharmacists, or international nurse prescribers whose scope differs from Alberta RN prescribing. Evidence on adverse events, diagnostic safety, long-term continuity, workload redistribution, and total cost remains incomplete. Because evidence was heterogeneous, no de novo meta-analysis was performed.

4.5. Research Implications

Future research should prospectively assess structured RN prescribing in primary care with implementation designs like stepped-wedge rollouts, interrupted time series, matched-comparator clinic comparisons, pragmatic hybrid effectiveness-implementation trials, and linked administrative data studies.

Research reports should specify the actual prescribing model including RN education and authorization method, clinical support tool, eligible conditions, formulary limitations, diagnostic-test authority, supervision or collaboration expectations, EMR workflow, clinical-escalation rules, frequency of FP/NP review, pharmacist role, audit process, and safety-netting with patients.

5. Conclusions

RN prescribing appears to have the potential to improve primary-care access and some selected clinical outcomes. The most evidence-supported interpretation of the current body of evidence is that RN prescribers are most likely to benefit primary care patients if they are used within a coordinated team that includes family physicians and NPs, rather than being used as stand-alone substitutes. In such a model, the RN prescriber provides effective and efficient management of defined, appropriate, protocolized care and medication pathways, while the family physician and NP provide comprehensive diagnosis, complex decision-making, high-risk prescribing, continuity and escalation. This, in turn, is likely to benefit patients most when it is combined with timely access, shared records and other information sources, clinical support tools, role clarity, patient-centered communication, follow-up responsibility, and routine safety evaluation. Direct, comparative, head-to-head studies of coordinated RN prescriber-FP/NP models are still needed to confirm this, but the current evidence strongly supports such integration rather than isolation.
