Nursing Practice Problem vs. Medical Practice Problem: Examples and Why Your PICOT Must Be Nursing-Focused
8 min read Discussion: Nursing practice problems vs. medical practice problems
Describe the difference between a nursing practice problem and a medical practice problem. Provide one example of each. Discuss why is it important to ensure your PICOT is based on a nursing practice problem.
Why this distinction matters
Many nursing students begin their evidence-based practice (EBP) project with a question such as “Which antibiotic works best for pneumonia?” or “Is drug A better than drug B for hypertension?” These are important clinical questions, but they are medical questions: the decisions belong to physicians and other prescribing providers, and a registered nurse cannot independently change practice based on the answer. An EBP project or capstone in nursing must instead address a nursing practice problem, one that nurses can identify, influence and solve within their own scope of practice.
What is a nursing practice problem?
A nursing practice problem is a clinical, safety, quality or patient-experience issue that nurses can address through independent nursing interventions within their legal scope of practice. Nursing focuses on protecting and promoting health and function, preventing illness and injury, facilitating healing and relieving suffering, and on human responses to health problems (American Nurses Association [ANA], 2021). Nursing practice problems therefore center on how patients respond to illness and care, and on processes nurses control.
Characteristics:
- Within the nurse’s scope of practice under the state Nurse Practice Act
- Addressed by interventions nurses can initiate without a new medical order, such as assessment, education, positioning, mobility, rounding, communication, infection prevention and comfort measures
- Linked to nurse-sensitive outcomes: falls, pressure injuries, catheter-associated urinary tract infections (CAUTI), central line infections, pain, patient satisfaction, readmissions related to discharge education, and nurse burnout and turnover
- Often described using nursing diagnoses, such as risk for falls or deficient knowledge
What is a medical practice problem?
A medical practice problem concerns the diagnosis and treatment of disease through decisions that fall within the scope of physicians and other licensed prescribers, such as nurse practitioners acting in a provider role. These problems involve choosing diagnostic tests, prescribing medications, determining doses, performing surgery or selecting a medical treatment plan.
Characteristics:
- Requires medical diagnosis or a prescriber’s order to act on
- Focuses on the disease process itself and its medical or surgical treatment
- Outcomes depend mainly on medical decisions, such as which drug, dose, test or procedure is used
Key differences at a glance
| Feature | Nursing practice problem | Medical practice problem |
|---|---|---|
| Focus | Human responses to illness, safety, function, comfort, education, care processes | Diagnosis and treatment of disease |
| Who can act on it | Registered nurses, independently | Physicians and other prescribers |
| Type of intervention | Independent nursing interventions (rounding, turning, teach-back, early mobility, bundles, sleep promotion) | Medications, diagnostic tests, surgery and medical procedures |
| Typical outcomes | Falls, pressure injuries, CAUTI, pain scores, knowledge, adherence, satisfaction, nurse retention | Disease control, cure rates, mortality from treatment choice, lab values driven by medication changes |
| Classification | Nursing diagnosis (e.g., risk for falls) | Medical diagnosis (e.g., community-acquired pneumonia) |
| Example question | Does hourly purposeful rounding reduce falls? | Is drug A or drug B more effective in treating pneumonia? |
Example of a nursing practice problem
Problem: Inpatient falls among older adults on a medical-surgical unit. Falls cause injuries such as fractures and head trauma, longer hospital stays and higher costs. Nurses can prevent many falls through risk assessment, purposeful hourly rounding, scheduled toileting, bed alarms, patient education and environmental safety, all of which are within nursing scope. Tailoring fall prevention to each patient’s risk factors has been shown to reduce falls in acute care hospitals (Dykes et al., 2010).
PICOT: In hospitalized adults aged 65 and older on a medical-surgical unit (P), does purposeful hourly rounding with scheduled toileting (I), compared with standard care (C), reduce the rate of falls (O) over three months (T)?
Example of a medical practice problem
Problem: Selecting the most effective antihypertensive medication for adults with uncontrolled stage 2 hypertension. Choosing between drug classes, such as an ACE inhibitor versus a calcium channel blocker, and determining doses are prescribing decisions made by physicians and other licensed prescribers.
PICOT (medical): In adults with stage 2 hypertension (P), does a calcium channel blocker (I), compared with an ACE inhibitor (C), lower systolic blood pressure more effectively (O) within 12 weeks (T)? A registered nurse cannot implement this change independently.
Turning a medical problem into a nursing problem
Many medical conditions have nursing dimensions. Instead of asking which medication to prescribe, ask what nurses can do to improve outcomes:
| Medical framing | Nursing framing |
|---|---|
| Which antihypertensive best lowers blood pressure? | Does nurse-led teach-back education on home blood pressure monitoring improve medication adherence and blood pressure control? |
| Which antibiotic best treats CAUTI? | Does a nurse-driven catheter removal protocol reduce CAUTI rates? |
| Which insulin regimen is best for type 2 diabetes? | Does structured nurse-led diabetes self-management education reduce HbA1c and readmissions? |
| Which drug treats postoperative pain best? | Does adding nonpharmacological interventions such as music therapy, repositioning or cold therapy reduce postoperative pain scores? |
| Which surgery is best for hip fracture? | Does early mobilization by nurses after hip surgery reduce length of stay and complications? |
Why your PICOT must be based on a nursing practice problem
- Scope of practice and legal authority: nurses must practice within the boundaries of their state Nurse Practice Act. A PICOT built on a medical problem would require prescribing or diagnostic decisions that registered nurses are not licensed to make, so the evidence could not be implemented by the nurse leading the project.
- Feasibility of implementation: EBP projects are meant to be translated into practice. When the intervention is within nursing control, nurses can plan, implement and evaluate change, often with PDSA cycles, without needing new medical orders for each patient.
- Measurable nurse-sensitive outcomes: nursing problems link to outcomes that reflect the quality of nursing care, such as falls, pressure injuries, CAUTI, pain and patient satisfaction, which nurses can track and improve.
- Professional accountability and identity: nursing has its own body of knowledge and evidence. Focusing on nursing problems strengthens nursing science, demonstrates nursing’s unique contribution to outcomes, and aligns with the AACN Essentials expectation that nurses translate evidence into practice to improve care (American Association of Colleges of Nursing [AACN], 2021).
- Course and program requirements: BSN, MSN and DNP programs typically require that EBP and capstone projects address problems within the student’s professional role. A medical PICOT is often rejected by instructors and must be revised.
- Interprofessional collaboration remains possible: a nursing PICOT does not exclude other professionals; nurses can lead projects that involve physicians, pharmacists and therapists, but the core intervention is nursing-led.
- Better patient outcomes: evidence-based nursing interventions improve safety, quality and patient experience, and nurses are positioned at the bedside to sustain these changes (Melnyk & Fineout-Overholt, 2023).
Quick checklist: is my PICOT a nursing problem?
- Can a registered nurse implement the intervention without a new medical order?
- Is the outcome nurse-sensitive and measurable by nursing staff?
- Does the problem involve safety, comfort, education, function, prevention or care processes?
- Would a nursing diagnosis describe the patient’s response?
- Is the comparison standard nursing care rather than a different medication or surgery?
Sample discussion post
A nursing practice problem is a clinical or quality issue that nurses can address independently within their scope of practice, focusing on patients’ responses to illness, safety, comfort, education and care processes (ANA, 2021). A medical practice problem involves the diagnosis and treatment of disease and requires decisions by physicians or other prescribers, such as choosing medications, tests or surgery. An example of a nursing practice problem is inpatient falls among older adults; nurses can reduce falls through risk assessment, purposeful hourly rounding, scheduled toileting and patient education, and tailored fall prevention programs have reduced falls in acute care (Dykes et al., 2010). An example of a medical practice problem is deciding whether a calcium channel blocker or an ACE inhibitor better controls stage 2 hypertension, which is a prescribing decision. It is important that a PICOT question be based on a nursing practice problem because nurses must practice within their legal scope, and the evidence must be something nurses can implement, measure and sustain. Nursing-focused PICOT questions lead to nurse-sensitive outcomes, strengthen nursing science and meet program expectations for translating evidence into practice (AACN, 2021; Melnyk & Fineout-Overholt, 2023).

Conclusion
The difference between nursing and medical practice problems lies in focus and authority: nursing problems address human responses and care processes that nurses can change independently, while medical problems involve diagnosing and treating disease through prescriber decisions. Grounding a PICOT question in a nursing practice problem ensures the project is legally appropriate, feasible, measurable and meaningful, allowing nurses to translate evidence into practice that improves patient outcomes.
