Brief Summary

This prospective, single-center observational study examines the relationship between perioperative nursing workload and safety-critical perioperative nursing care in the operating rooms of Agri Training and Research Hospital. Guided by the Donabedian structure-process-outcome framework, the study will directly observe eligible surgical procedures to record objective, procedure-level workload indicators (interruptions, task-switching, concurrent duties, procedure duration, shift timing, and equipment/supply shortages) together with the observed perioperative nurse's self-reported workload using the Turkish NASA Task Load Index (NASA-TLX), and a structured observation of nine safety-critical perioperative nursing care tasks (identification/procedure/site verification, allergy and critical preoperative information verification, positioning and pressure-injury prevention, normothermia, surgical counts, specimen/label verification, equipment and implant readiness, handoff, and documentation). Any delayed or omitted safety-critical care items, and any near-miss or process-deviation events identified and corrected before patient harm, will also be recorded using standardized forms. The study does not involve patients as direct research participants; only the perioperative work environment and voluntarily participating nurses are observed, and routine clinical care, staffing assignments, and surgical decisions will not be modified. The primary aim is to determine whether higher perioperative nursing workload is associated with a higher rate of missed/delayed safety-critical nursing care at the procedure level; secondary aims examine the association between missed safety-critical care and near-miss/process-deviation events, and, if sufficient events occur, whether missed safety-critical care mediates part of the relationship between workload and near-miss/process-deviation events.

Outcome Measures

Primary Outcomes (1)

  • Missed Safety-Critical Perioperative Nursing Care Index

    Proportion of applicable safety-critical perioperative nursing care items (patient/procedure/surgical-site verification, allergy and critical preoperative information verification, positioning and pressure-injury prevention, normothermia, surgical count, specimen/label verification, equipment/implant readiness, safe handoff, and required documentation) scored as delayed/partial or not done, divided by the total number of applicable safety-critical items for that procedure, as directly observed using the Safety-Critical Perioperative Nursing Care Observation Form.

    Assessed once per surgical procedure during the intraoperative period (from procedure start to end), for procedures observed over approximately 8-12 weeks between October 2026 and December 2026

Secondary Outcomes (3)

  • Occurrence of Near-Miss/Process-Deviation Events

    Assessed once per surgical procedure during the intraoperative period, for procedures observed over approximately 8-12 weeks between October 2026 and December 2026

  • Total Objective Workload Events per Procedure

    Assessed once per surgical procedure during the intraoperative period, for procedures observed over approximately 8-12 weeks between October 2026 and December 2026

  • Perceived and Objective Perioperative Nursing Workload

    Assessed once per surgical procedure, shortly after procedure completion, for procedures observed over approximately 8-12 weeks between October 2026 and December 2026

Study Arms (1)

Perioperative Nurses and Observed Surgical Procedures

Perioperative nurses working in the operating rooms of Agri Training and Research Hospital who voluntarily consent to participate, together with the eligible elective/planned surgical procedures in which a participating nurse is actively on duty during the study period. Each eligible procedure is directly observed by a researcher using a standardized objective workload observation form and a structured safety-critical perioperative nursing care observation form; near-miss/process-deviation events are logged using a standardized form; and the observed nurse completes the Turkish NASA Task Load Index (NASA-TLX) shortly after the procedure. No experimental intervention, diagnostic test, or change to routine clinical care is assigned; participants are observed under usual perioperative practice.

Other: Structured Direct Observation and Workload Assessment

Interventions

No experimental intervention is administered. Eligible surgical procedures are directly observed by a researcher using a standardized Procedure and Objective Workload Observation Form and a structured Safety-Critical Perioperative Nursing Care Observation Form, and any near-miss/process-deviation events are recorded on a standardized log form. The observed perioperative nurse additionally completes the Turkish adaptation of the NASA Task Load Index (NASA-TLX) shortly after the procedure to assess self-reported workload. Routine clinical care, staffing assignments, and surgical decision-making are not modified by these observation and assessment procedures.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Perioperative (operating room) nurses working at Agri Training and Research Hospital, and the elective/planned surgical procedures in which participating nurses are actively on duty during the study period, meeting the eligibility criteria above. Patients undergoing the observed procedures are not direct research participants.

You may qualify if:

  • Actively on duty as a perioperative (operating room) nurse at Agri Training and Research Hospital
  • At least 3 months of operating room experience
  • Voluntary agreement to participate and to complete the post-procedure NASA-TLX form

You may not qualify if:

  • Extended leave or medical report resulting in inactive duty during the data collection period
  • Withdrawal from the study
  • Failure to complete the post-procedure workload assessment form
  • Performed in the operating rooms of Agri Training and Research Hospital
  • Involves a participating perioperative nurse who is actively on duty
  • Elective or planned surgical procedure
  • At least a portion of the safety-critical care items are directly observable
  • Emergency/resuscitative circumstances that would affect the clinical flow being observed
  • Procedures in which observation could not be completed
  • Observation records missing core variables

Data Sharing

IPD Sharing
Will not share

No plan to share individual participant data is currently in place. The dataset consists of de-identified, procedure-level observation and workload records without patient identifiers; data sharing beyond the study team is not currently planned given the small single-center sample and the observational nature of the data.
