The Relationship Between the ASA Score Determined by Operating Room Nurses and Intubation Duration

The objective of this study is to The objective of this study was to ascertain the extent to which operating room nurses assign ASA scores and to assess the reliability of these scores in predicting significant risk factors, including the necessity for mechanical ventilation in patients.

Study Overview

• Status: Completed
• Conditions: The Individual Must be 18 Years of Age or Older; The Individual Must be Willing to Participate in the Study

Detailed Description

The present research is to be conducted as a prospective observational study. The present prospective observational study is to be conducted over a 3-month period between April 1, 2025, and July 1, 2025, at a single centre, with the involvement of 36 nurses, 12 anesthesiologists (12 operating tables), and 80 patients working in the operating room of Zonguldak Atatürk State Hospital, who evaluate patients in a pre- and post-operative assessment clinic. The sociodemographic information of the nurses and anesthesiologists will be recorded using "Personal Information Form 1" and "Personal Information Form 2". Prior to undergoing surgery, patients' ASA scores and sociodemographic information will be evaluated by operating room nurses and anesthesiologists, who will record this data using "Personal Information Form 3". Patients will be followed up until they are discharged from the clinic, and their mechanical ventilation needs will be recorded. The ASA scores assigned by operating room nurses and anesthesiologists will be analysed in relation to the necessity for mechanical ventilation.

Study Population

This study was conducted at Zonguldak Atatürk State Hospital between 1 April and 1 July 2025. The operating room was staffed by 36 nurses, 12 anesthesiologists (across 12 operating tables) and 80 patients. A review of extant research on the subject was conducted, and a G Power analysis was subsequently performed. This analysis indicated that, in order to achieve 80% power within a 95% confidence interval for an effect size of d=0.8, it is necessary to include 80 individuals meeting the inclusion criteria in the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Determining the sociodemographic information of the nurse using "Personal Information Form 1"	The nurse's assessment is a nine-item form that includes information such as age, gender, professional work experience, experience working in an operating room, work style, average weekly working hours, income level, and whether or not they have received ASA Physical Status Classification training.	From April 2025 to June 2025
Determining the sociodemographic information of anesthesiologists using "Personal Information Form 3"	This is an 8-item form that includes the anesthesiologist's age, gender, professional work experience, operating room experience, work style, average weekly working hours, income level, and whether they have received ASA Physical Status Classification training.	From April 2025 to June 2025
Determining the sociodemographic information of the patient's using "Personal Information Form 3"	This is an 8-item form that includes the patient's age, gender, chronic diseases, previous surgical procedures, Glasgow Coma Scale score, ASA class score, need for mechanical ventilation, and number of days the patient has been intubated.	From April 2025 to June 2025

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Comparing patients' ASA scores with their need for mechanical ventilation	The ASA scores given to patients by operating room nurses and anesthesiologists will be compared with the likelihood of them needing mechanical ventilation. For analyzing the differences between two independent groups with a normal distribution, an independent t-test will be applied; for analyzing the differences between more than two independent groups, an ANOVA test will be applied.	From April 2025 to June 2025
