15.1 Interdisciplinary Team Collaboration

The Interprofessional Team on a Medical-Surgical Unit

ANCC Domain III (Professional Role, roughly 21% of the MEDSURG-BC exam) tests whether you know who does what on the healthcare team and where each member's scope of practice begins and ends. Scope of practice is the legal boundary of activities a professional may perform, defined by state law (for nursing, the state Nurse Practice Act), professional licensure, and facility policy. Board questions frequently ask which team member is the appropriate consult, or which task falls inside or outside a role.

Clinical pearl: When an exam item describes a new problem and asks whom to collaborate with, match the problem to the discipline's unique function — swallowing to SLP, ambulation to PT, medication reconciliation to the pharmacist, placement and resources to social work or case management.

Scope of Practice Boundaries

Scope of practice questions hinge on three rules. First, only the RN can perform the steps of the nursing process that require clinical judgment: comprehensive assessment, nursing diagnosis, outcome identification, planning, and evaluation. Second, the LPN/LVN practices under the direction of an RN or provider and cares for patients whose conditions are stable and predictable; the LPN collects data but does not perform the initial or independent assessment. Third, UAPs are unlicensed; every task they perform is delegated by an RN who retains accountability for the outcome. Facility policy and state law further narrow these boundaries — for example, many states prohibit LPNs from administering IV push medications or initiating blood products. When two answers look defensible on an exam, choose the one that keeps judgment-dependent work with the RN.

Interprofessional Rounds and Care Conferences

Interprofessional rounds (also called structured interdisciplinary rounds) bring the RN, provider, case manager, pharmacist, therapist, and social worker together — ideally at the bedside — to review each patient's progress against the plan of care. Effective rounds are brief, standardized, and goal-oriented: each discipline reports status, barriers to discharge are named, and the team updates a shared daily goal. Evidence links structured bedside rounds to shorter length of stay, fewer adverse events, and better patient satisfaction because problems surface the same day instead of at discharge.

A care conference (or family meeting) is a longer, scheduled session for complex situations: conflicting goals of care, poor prognosis, difficult discharge placement, or a treatment plan spanning many disciplines. The RN's role is to contribute the 24-hour nursing picture — functional status, symptom burden, family dynamics — and to advocate for the patient's stated preferences. Best practices include agreeing on one spokesperson to avoid contradictory messages, documenting decisions and who made them, and confirming the family's understanding with teach-back.

Structured Communication: SBAR and I-PASS

SBAR (Situation, Background, Assessment, Recommendation) is the standard framework for concise communication, especially urgent nurse-to-provider calls:

• Situation — who you are, the patient, and the problem in one sentence: "Mr. Alvarez in 412 has a new blood pressure of 84/50 with a heart rate of 118."
• Background — relevant context: post-operative day 1 after bowel resection, last hemoglobin, current infusions.
• Assessment — your clinical read: "He is pale, increasingly lethargic, and his drain output has doubled; I am concerned about bleeding."
• Recommendation — what you want and when: "I would like you to see him now; may I draw a stat hemoglobin and start a fluid bolus per protocol?"

I-PASS is the evidence-based structure for handoffs (shift change, unit transfer): Illness severity (stable, watcher, unstable), Patient summary (events leading to admission, hospital course, ongoing assessment, current plan), Action list (to-do items with timing and ownership), Situation awareness and contingency planning (if/then statements), and Synthesis by receiver (the receiving clinician restates the plan — a built-in read-back). A landmark multicenter study found the I-PASS bundle reduced medical errors by about 23% and preventable adverse events by about 30%.

Nurse-Physician Communication and Graded Assertiveness

Authority gradients — a nurse hesitating to challenge a physician — are a root cause of preventable harm. Graded assertiveness gives the RN a scripted escalation ladder:

1. Inquiry — a tentative opening: "I notice the potassium is 2.9; should we treat before the next diuretic dose?"
2. Concern statement with CUS words — "I am Concerned. I am Uncomfortable. This is a Safety issue." CUS language signals that routine conversation is over.
3. Two-challenge rule — if the concern is not addressed, state it a second time, more forcefully, with supporting data. The second challenge must be acknowledged.
4. Chain of command — if there is still no safe response, escalate: charge nurse, house supervisor, rapid response team, then the attending's supervisor or chief of staff. Document each step objectively.

Clinical pearl: Exam items love the two-challenge rule. If a nurse reports a concern and the provider dismisses it, the correct next action is to restate the concern with data and, if unresolved, activate the chain of command — never to simply document and wait while the patient deteriorates.

Collaborative Problem Solving and Conflict Resolution

Teams solve problems best with a shared, structured approach: define the problem with data, hear each discipline's analysis, generate options against the patient's goals, decide explicitly, and assign ownership with follow-up. When conflict arises, the Thomas-Kilmann modes describe responses: avoiding, accommodating, competing, compromising, and collaborating — collaborating (high assertiveness, high cooperation) produces the most durable solutions for patient-care disagreements. Practical rules: address the behavior or decision, not the person; use "I" statements tied to patient safety; hold crucial conversations in private, promptly, and with data in hand; and involve a neutral party (charge nurse, manager, or ethics committee) when the dyad is stuck. Unresolved conflict that affects safety belongs in the chain of command, not in the break room.
