Conceptual and operational definitions of the components of the nursing diagnosis Acute Pain (00132).
Marisa Dibbern Lopes Correia, Erika Christiane Marocco Duran
PMID 29267544WHAT IT FOUND
This review defines the signs and symptoms nurses should look for to diagnose acute pain, especially in patients who cannot speak.
It lists specific behavioral and physical indicators, such as facial grimacing, protective movements, and changes in heart rate, to guide assessment when verbal reports are impossible.
Key findings
01The review established conceptual and operational definitions for 17 defining characteristics and three related factors of the nursing diagnosis Acute Pain, drawing from 16 studies and gray literature.
02For patients unable to communicate verbally, pain assessment relies on observational tools and specific behavioral signs like grimacing, protective behavior, and physiological changes such as pupil dilation or increased heart rate.
03The included evidence was generally low level, with no studies at level I or II, and many studies excluded patients who could not communicate, highlighting a gap in validated assessment methods for this specific group.

What it does not show
The review included no Level I or II evidence, meaning the definitions are based on lower-quality observational and descriptive studies. Six of the included studies excluded patients who could not communicate, which is the exact population this review aims to help assess, creating a significant evidence gap. The review relied on gray literature (books, dictionaries) to fill gaps, which may not have the same rigorous validation as peer-reviewed clinical studies. The definitions are derived from a review of existing literature and expert opinion, not from a new clinical trial testing their accuracy in real-time patient care.
The easy way to misread this
Do not treat these definitions as a validated diagnostic tool that guarantees accurate pain identification. The review itself notes that no Level I or II evidence supports these specific operational definitions, and many source studies excluded non-verbal patients. Use these signs as a guide for assessment, but remain aware that the accuracy of these indicators for the non-verbal ICU population has not yet been clinically validated in a robust trial.
