Patient Safety Event Analysis and Capstone Portfolio Assembly

Why This Lesson Matters

As a surgical technologist, you will work in an environment where a single lapse in communication, sterile technique, or instrument management can cause serious, preventable harm. The capstone project asks you to look back at everything you have learned and apply it to a real-world type safety problem. Completing a root-cause analysis and assembling your portfolio proves—to faculty, to employers, and to yourself—that you can think critically about patient safety and that you have mastered the full scope of the NBSTSA CST exam content areas.

What Is a Patient Safety Event?

A patient safety event is any incident, near-miss, or hazardous condition that has caused or could cause unintended harm to a patient. In the perioperative setting, common examples include retained surgical items (RSI), wrong-site or wrong-patient surgery, surgical site infections (SSIs), and medication errors at the sterile field. The Joint Commission classifies the most serious of these as sentinel events—unexpected occurrences that result in death, permanent harm, or severe temporary harm. Reviewing sentinel event data and alert publications from The Joint Commission is a recognized way to identify system-level patterns and evidence-based corrective strategies.

The Fishbone (Cause-and-Effect) Framework

The fishbone diagram, also called the Ishikawa diagram, is a structured root-cause analysis tool widely used in healthcare quality improvement. It earns its name from its shape: a horizontal arrow pointing to the problem (the "head"), with diagonal branches (the "bones") representing categories of contributing factors.

For a perioperative safety scenario, appropriate categories include:

• Aseptic practice – breaks in sterile technique, improper draping, traffic violations in the OR
• Communication – failures in briefing, time-out, handoff, or count reporting
• Instrumentation – missing items, incorrect counts, damaged instruments
• Sterilization and processing – inadequate decontamination, incorrect cycle parameters, improper packaging
• Human factors – fatigue, distraction, unfamiliarity with procedure
• Environment – room setup, equipment malfunction, OR traffic

To build the diagram, write the problem statement in the "head" box. For each category, ask "Why could this have happened?" and branch specific contributing factors off the diagonal lines. Once the diagram is complete, the most likely root causes—those factors that, if corrected, would most probably prevent recurrence—become the focus of your corrective action recommendations.

Writing the Formal Safety Report

Your report must be at least 1,500 words and follow a logical structure:

1. Introduction – Briefly describe the safety scenario and explain why the event type matters in the perioperative setting.

2. Root-Cause Analysis – Present your completed fishbone diagram and narrate the contributing factors you identified in each category.

3. Root Cause Identification – State the most probable root cause(s) and explain your reasoning with evidence.

4. Corrective Action Recommendations – Propose at least three specific, actionable steps to prevent recurrence. Each recommendation must be supported by a credible reference such as the AST Standards of Practice, AORN Guidelines for Perioperative Practice, or a Joint Commission sentinel event resource. Vague suggestions such as "be more careful" are not acceptable—recommendations must be measurable and assignable (for example, "implement a standardized instrument count policy using AORN count guidelines at case opening, before cavity closure, and at skin closure").

5. Conclusion – Summarize the analysis and reinforce the connection between the corrective actions and patient safety outcomes.

6. Reference List – Format references consistently using the style specified by your program.

Assembling the Capstone Portfolio

Your portfolio is the physical or digital record that demonstrates program-wide competency. It must be organized so that any reviewer—including a future employer—can quickly find evidence aligned to each NBSTSA CST exam content domain.

The four broad NBSTSA CST exam content areas and the portfolio sections that map to them are:

| NBSTSA CST Domain | Portfolio Section Content |

|---|---|

| Perioperative Care | Case packets, surgical count sheets, competency checklists for scrub and circulating roles |

| Ancillary Duties | Setup photos or diagrams, sterilization logs, decontamination competency checklists |

| Basic Science Concepts | Anatomy and microbiology assignments, aseptic technique documentation |

| Specialty Surgery | Specialty case reports (orthopedic, cardiovascular, OB/GYN, neurosurgery, etc.) |

Every section requires labeled dividers, and the portfolio opens with a table of contents. Required items for clearance include: all case packets, completed count sheets, at least one setup photo or diagram per specialty area, competency checklists signed by clinical faculty, your safety analysis report, and a one-page reflective self-assessment in which you evaluate your own growth over the program and identify areas for continued professional development.

Safety Points to Remember

• Scope of practice is non-negotiable. Your recommendations must reflect the surgical technologist's role, not tasks reserved for the registered nurse or surgeon.
• The Universal Protocol (time-out, site marking, pre-procedure verification) is the recognized standard for preventing wrong-site, wrong-procedure, and wrong-patient events. Always reference it when analyzing such scenarios.
• Surgical counts are a shared responsibility. The scrub technologist and circulating nurse jointly perform and document counts. Documenting a count you did not actually perform is a patient safety violation.
• Evidence-based recommendations carry more weight than opinion. Anchor every corrective action to a named standard or guideline.

Clearing the Capstone

Faculty will score your safety report on a rubric requiring a minimum score of 80% across four criteria: word count, correct framework application, credible references, and actionable recommendations. Your portfolio is evaluated against a completeness checklist—every required section must be present and correctly labeled before you are cleared for the oral defense. The oral defense is your final opportunity to demonstrate that you understand what you submitted and are ready to practice as a competent, safety-focused surgical technologist.
