Perioperative nursing — encompassing preoperative, intraoperative, and postoperative phases — is one of the highest-acuity and highest-accountability settings in nursing. Every phase has clearly nurse-owned safety responsibilities: preoperative verification, intraoperative monitoring, postoperative assessment and handoff. The perioperative environment is also exceptionally well-measured: The Joint Commission, CMS, and AORN (Association of periOperative Registered Nurses) have published detailed standards and outcome benchmarks, giving capstone students a wealth of evidence-based targets. The challenge is framing a capstone that is genuinely nurse-driven rather than physician-dependent, and that has a measurable outcome achievable within your project timeline.
Understanding the three perioperative phases and nursing's role
| Phase | Setting | Key nurse responsibilities | High-yield capstone targets |
|---|
| Preoperative | Preop holding area, same-day surgery unit, pre-admission testing clinic | Surgical site marking verification, consent confirmation, allergy reconciliation, preop antibiotic administration timing, normothermia prep, patient and family education, NPO status verification, skin prep instruction | Preop antibiotic timing compliance, surgical site marking protocol compliance, preop patient education completion rate, informed consent documentation quality |
| Intraoperative | Operating room | Surgical Safety Checklist (WHO/TJC) facilitation, surgical count (instruments/sponges/sharps), positioning and pressure injury prevention, normothermia maintenance (forced air warming, warm IV fluids), sterile field maintenance, medication labeling on the sterile field | Surgical Safety Checklist compliance rate, retained surgical item (RSI) prevention, intraoperative normothermia rate, medication labeling compliance |
| Postoperative / PACU | Post-anesthesia care unit (PACU), surgical floor | Airway and ventilation assessment, pain management, nausea and vomiting prevention (PONV), hypothermia monitoring and rewarming, handoff communication (SBAR or I-PASS), discharge criteria assessment (Aldrete Score), patient education before discharge | PACU handoff quality and completeness, PONV management protocol compliance, normothermia on PACU arrival, pain control on arrival and at discharge, Aldrete Score documentation |
Topic ideas: Surgical safety checklist and wrong-site surgery prevention
The WHO Surgical Safety Checklist — nursing's role
The WHO Surgical Safety Checklist (2009) is one of the most evidence-supported safety interventions in all of medicine — it reduced mortality by 47% and complications by 36% in the landmark Haynes et al. study across 8 countries. The checklist has three phases: Sign In (before anesthesia induction — identity, site, consent, anesthesia equipment, pulse oximetry), Time Out (before surgical incision — entire team confirms patient identity, site, procedure, antibiotic administration, and critical steps), and Sign Out (before patient leaves the OR — instrument count confirmed, specimen labeled, key concerns for recovery). The circulating nurse is the designated facilitator of the Time Out in most institutions. Compliance failures — partial, rushed, or skipped Time Outs — are directly linked to wrong-site surgery (WSS) events, which remain on The Joint Commission's Sentinel Event list. A perioperative nursing capstone targeting Time Out quality and compliance addresses a nurse-owned, high-stakes safety practice with a clear measurement framework.
| Topic | Level | PICOT starter | Primary outcome |
|---|
| Surgical Safety Checklist Time Out compliance audit and education | BSN/MSN | In circulating nurses in a hospital operating room department, does a structured Time Out quality improvement program (direct observation audit of Time Out compliance using AORN criteria, individual feedback, team debriefing sessions, visual cue laminated card posted in each OR) compared to current Time Out practice without structured audit or feedback... | Time Out compliance rate (all required elements completed before first incision); Time Out duration (seconds); nurse-reported Time Out interruption rate; observation-to-intervention time for compliance failures |
| Wrong-site surgery prevention: site marking protocol compliance | BSN/MSN | In surgical patients undergoing lateralized or multi-level procedures at an ambulatory surgery center, does a nurse-led surgical site marking verification program (nurse confirms site mark with signed consent and imaging at preop check-in; mark absent → procedure postponed until surgeon marks with patient awake and confirming; nurse documents verification in EMR) compared to surgeon-only site marking without systematic nurse verification step... | Surgical site mark documentation compliance rate at preop check-in; rate of discrepancies identified between site mark, consent, and imaging; Time Out delay rate due to absent or unverified site mark; patient report of preop engagement in site marking confirmation |
Topic ideas: Surgical site infection (SSI) prevention
SSI by the numbers
Surgical site infections are among the most common healthcare-associated infections, accounting for approximately 20% of all HAIs. SSIs affect an estimated 2–5% of patients undergoing inpatient surgery, contribute to 77% of surgery-related deaths, and add an average of $20,000–$90,000 per case in treatment costs. CMS tracks SSI rates as a hospital-acquired condition (HAC), making SSI prevention a financial and regulatory priority in addition to a patient safety priority. The CDC's National Healthcare Safety Network (NHSN) stratifies SSI into: superficial incisional (skin and subcutaneous tissue), deep incisional (fascia and muscle), and organ/space (any anatomical structure opened during surgery). Nursing owns several of the most impactful SSI prevention interventions: preoperative skin preparation instruction, appropriate hair removal technique (clipping vs. shaving), preoperative bathing with chlorhexidine gluconate (CHG), and postoperative wound assessment and dressing management.
| Topic | Level | PICOT starter | Primary outcome |
|---|
| Preoperative CHG bathing compliance and SSI rate | BSN/MSN | In adult patients scheduled for elective orthopedic or colorectal surgery at a community hospital, does a nurse-delivered structured preoperative CHG bathing instruction program (nurse calls patient 48 hours before surgery; instructs on correct CHG application for 2 consecutive nights preoperatively; mails CHG wipes with instruction card; confirms compliance at preop check-in) compared to standard preop instruction sheet without nurse-led education or compliance confirmation... | Patient-reported CHG bathing compliance rate at preop check-in; SSI incidence (superficial and deep incisional) at 30 days post-surgery (NHSN definition); patient knowledge score (pre/post — correct CHG application technique) |

Topic ideas: PACU handoff and postoperative communication
| Topic | Level | PICOT starter | Primary outcome |
|---|
| Structured SBAR handoff tool implementation in PACU | BSN/MSN | In patients transferring from the operating room to the PACU at a community hospital, does implementation of a structured SBAR perioperative handoff tool (standardized form completed by scrub/circulating nurse and anesthesia, reviewed by PACU nurse before accepting patient) compared to unstructured verbal handoff at PACU admission... | Handoff completeness score (validated Handoff CEX or audit checklist — percentage of required elements communicated); PACU adverse event rate (unplanned respiratory intervention, hypotension requiring vasopressor, pain NRS ≥8/10 on arrival); nurse-reported handoff satisfaction score (Likert) |
| I-PASS handoff bundle for PACU-to-floor transfer | BSN/MSN | In adult surgical patients transferring from the PACU to a medical-surgical or orthopedic floor unit, does implementation of a nurse-driven I-PASS handoff bundle (Illness severity, Patient summary, Action list, Situation awareness and contingency plans, Synthesis by receiver — with standardized paper or EMR-embedded tool) compared to current PACU-to-floor handoff practice without standardized structure... | Information omission rate on audit of transfer documentation; adverse event rate within 4 hours of PACU transfer (unplanned rapid response activation, pain NRS ≥8, PONV requiring IV antiemetic, unplanned return to OR); nurse-reported receiving satisfaction (Likert) |

Theoretical frameworks for perioperative nursing capstones
| Framework | Best suited for | Application |
|---|
| High Reliability Organization (HRO) Theory | Surgical Safety Checklist compliance, wrong-site surgery prevention, retained surgical items, medication labeling | The OR is arguably the original high-hazard environment in healthcare — combining complex technology, time pressure, hierarchy, and irreversible consequences of failure. HRO theory's five principles apply directly: preoccupation with failure (the Time Out exists because every surgical team is one distraction away from operating on the wrong site), reluctance to simplify (standardized checklists resist the "we know this patient" cognitive shortcut), and deference to expertise (the circulating nurse has the authority to stop the procedure if the Time Out is not completed). |
| Iowa Model of EBP | SSI prevention bundle implementation, CHG bathing protocol, normothermia protocol rollout | Standard EBP implementation framework. Problem trigger (SSI rate above NHSN benchmark, normothermia protocol compliance audit gap, CHG bathing instruction inconsistency identified in preop nursing survey) → form interprofessional team → critically appraise CDC/AORN/ERAS evidence → pilot on one procedure type or one OR team → evaluate with pre/post data → sustain through policy and competency. |
| Donabedian's Structure-Process-Outcome Model | PACU handoff quality, PONV protocol compliance, ERAS program evaluation | Perioperative care quality is well-suited to Donabedian because all three elements are clearly defined: Structure (staffing ratios, PACU nurse:patient ratio, electronic handoff tool availability, ERAS nurse coordinator position), Process (Time Out completion rate, CHG bathing compliance, SBAR handoff documentation rate, PONV risk stratification), and Outcome (SSI rate, PACU adverse events, PONV incidence, LOS, 30-day readmission). Your capstone targets process measures directly and links them to structural changes that support the processes and outcome improvements that result. |
Scope caution: perioperative capstone limitations
- OR access requires institutional partnership: direct observation of intraoperative practice (Time Out compliance, normothermia management, sterile technique) requires OR access that not all students will have. If you do not have OR clinical placement, focus your capstone on the preoperative or PACU phases — both are fully accessible to perioperative and med-surg nurses
- SSI outcome requires 30-day follow-up: CDC/NHSN SSI definitions require surveillance for 30 days post-procedure (90 days for implant surgery). If your project timeline is less than 30 days after the final surgical case, SSI cannot be a primary outcome — use process measures (CHG compliance rate, antibiotic timing compliance) instead
- ERAS is a team intervention: ERAS program outcomes (LOS, opioid consumption, readmission) depend on surgeon, anesthesiologist, dietitian, and physical therapy compliance as well as nursing compliance. Frame your capstone as evaluating the nursing-owned elements of ERAS (preop education, normothermia, early ambulation encouragement) rather than claiming credit for overall ERAS outcomes
- Retained surgical items (RSI) are sentinel events: RSI prevention (instrument/sponge/needle counts) is a critical perioperative safety topic, but RSI events are so rare at any single institution that you cannot use RSI incidence as an outcome measure in a capstone-length project. Focus on count documentation compliance rate and count protocol adherence as your process outcomes

Frequently asked questions
What is ERAS and what is nursing's role in it?Enhanced Recovery After Surgery (ERAS) is a multimodal, evidence-based perioperative care protocol designed to reduce surgical stress, maintain physiological function, and accelerate recovery. The ERAS Society has published protocols for more than 20 procedure types. Core ERAS elements include: preoperative carbohydrate loading (up to 2 hours before surgery for clear carbohydrate drink — replacing traditional NPO-after-midnight), multimodal analgesia (minimizing opioids through scheduled acetaminophen, NSAIDs, nerve blocks, and gabapentinoids), early oral nutrition (clear liquids within 2–4 hours of surgery, solids by day 1), early mobilization (ambulation within 4–8 hours of surgery), normothermia maintenance, and minimizing IV fluids (goal-directed fluid therapy). Nursing owns the most patient-facing elements: preoperative ERAS education (explaining what to expect, carbohydrate loading instructions, early ambulation expectations), pain assessment and non-opioid analgesic scheduling, normothermia monitoring, early ambulation encouragement in PACU and on the floor, and early oral intake initiation. Nursing capstones targeting ERAS should focus on these nurse-owned elements and use process compliance rates and immediate postoperative outcomes (pain scores, opioid use, time to ambulation) as outcome measures.
What is the Aldrete Score and how is it used in PACU nursing?The Modified Aldrete Score (Post-Anesthesia Recovery Score) is a validated 10-point scoring system used to determine readiness for PACU discharge. It assesses five parameters — activity (ability to move extremities), respiration, circulation (blood pressure vs. preoperative value), consciousness, and oxygen saturation — each scored 0, 1, or 2. A score of 9–10 indicates readiness for PACU phase 1 discharge to phase 2 recovery or a surgical floor. The Aldrete Score is nurse-administered and nurse-documented — it is one of the clearest examples of nursing independently determining patient readiness for transition. In a perioperative nursing capstone, Aldrete Score documentation compliance rate (scored and documented at defined intervals per PACU protocol) is a clean, measurable process outcome. A mismatch between Aldrete Score and actual discharge time is a quality gap worth investigating: patients discharged with low Aldrete Scores, or patients with high Aldrete Scores held in PACU for non-clinical reasons (boarding), both represent improvement opportunities.
