Selecting Appropriate Measures for Assessing Preoperative Stress in Surgical Patients

QUESTION

Three nurse researchers were collaborating on a study of the effect of preoperative visits to surgical patients by operating room nurses on the stress levels of those patients just before surgery. One researcher wanted to use the patients’ self-reports to measure stress; the second suggested using pulse rate and blood pressure; and the third recommended using an observational measure of stress. Which measure do you think would be the most appropriate for this research problem? Can you suggest other possible measures of stress that might be even more appropriate? Provide a rationale for your response.

ANSWER

Selecting Appropriate Measures for Assessing Preoperative Stress in Surgical Patients

Introduction

Assessing preoperative stress in surgical patients is crucial as elevated stress levels can impact surgical outcomes and patient well-being. When choosing measures to evaluate stress in this context, it is essential to consider the strengths and limitations of each method. In this essay, we will discuss the appropriateness of three proposed measures for assessing preoperative stress and suggest additional measures that may be even more suitable.

Proposed Measures

Self-Reports
Appropriateness: Self-reports can provide valuable subjective insights into patients’ emotional states and perceptions of stress. However, they may be influenced by patients’ ability to express their feelings accurately, and some individuals may not be comfortable reporting their stress levels.
Rationale: Self-reports are valuable in understanding patients’ subjective experiences, making them a valid measure for assessing preoperative stress. However, they should be complemented with objective measures to ensure a comprehensive assessment.

Pulse Rate and Blood Pressure:
Appropriateness: Physiological measures like pulse rate and blood pressure can offer objective indicators of stress, as they often increase in response to stressors. However, they may not capture the full spectrum of emotional or psychological stress.
Rationale: Physiological measures can provide quantifiable data, which is valuable for assessing stress objectively. These measures are suitable for capturing the body’s immediate stress response, but they should be used in conjunction with self-reports or observational measures for a holistic evaluation.

Observational Measure of Stress:
Appropriateness: Observational measures, such as facial expressions, body language, or vocal cues, can offer insights into patients’ stress levels that they might not be able to communicate verbally. However, they may require trained observers and may not always reflect internal emotional states accurately.
Rationale; Observational measures can be valuable for assessing stress in cases where patients cannot self-report effectively, such as young children or individuals with communication difficulties. When used in conjunction with self-reports and physiological measures, they provide a more comprehensive assessment.

Additional Measures

Salivary Cortisol Levels:
Appropriateness: Salivary cortisol levels can provide an objective biological marker of stress, as cortisol is a stress hormone. It offers a more extended timeframe for assessing stress compared to pulse rate and blood pressure.
Rationale: Measuring salivary cortisol levels before and after preoperative visits can provide insights into the physiological response to stress over time.

Psychological Assessments:
Appropriateness: Standardized psychological assessments, such as anxiety or depression scales, can provide a broader understanding of patients’ emotional well-being and their predisposition to stress.
Rationale: Incorporating psychological assessments can help identify patients with preexisting anxiety or depressive tendencies, allowing for tailored interventions.

Coping Strategy Surveys:
Appropriateness: Assessing patients’ coping strategies and resilience can provide insights into their ability to manage stress effectively.
Rationale: Understanding how patients cope with stress can guide interventions aimed at enhancing their coping skills and reducing preoperative anxiety.

In conclusion, assessing preoperative stress in surgical patients requires a multidimensional approach. While self-reports, physiological measures, and observational methods each offer unique insights, using a combination of these methods, along with additional measures like salivary cortisol levels, psychological assessments, and coping strategy surveys, ensures a more comprehensive evaluation of preoperative stress. The choice of measures should be tailored to the specific patient population and research objectives, aiming for a holistic understanding of stress in this critical healthcare context.
