About

Currently, there is no observational pain scale for use in the outpatient setting for adult patients. An observational pain scale can allow for objective measurement of pain in patients over time and after treatment without the bias associated with self-report. Currently chronic pain patients are asked to rate their pain many times throughout their care, often over years. This introduces a bias in reporting as a pain a person is currently experiencing will seem more severe then a remembered pain event. A behavioral pain scale would allow for an objective measurement of pain that is reliable across multiple raters and comparable over time, which can help in judging the success of pain treatments.

Full description

This is a prospective observational study. No changes in therapy will be initiated due to the information gathered by its protocol. All medical decisions will be based on the management of the clinical team. Data will be gathered during the subject's clinical visit, from the subject, and from the nursing staff caring for the subject.

The Chronic Pain Behavioral Pain Scale for Adults was developed by the research team based on behavior pain scales used in other populations and the clinical expertise of Chronic Pain specialists in the Hershey Medical Center Chronic Pain department.

Patients will be scored on the Chronic Pain Behavioral Pain Scale for Adults and the standard 11 point numeric rating scale (Jensen, Turner et al., 1996), on intake. Scoring will be done by the patient's assigned nurse and a member of the research team, at the time when the numeric pain score is typically obtained. The patient will be scored again on both the Chronic Pain Behavioral Pain Scale for Adults and the standard numeric rating pain scale at the conclusion of their procedure, again at the time when the numerical pain score is typically obtained. Scoring will again be done by the patient's assigned nurse and a member of the research team. The Chronic Pain Behavioral Pain Scale for Adults will be tested for inter-rater reliability using the paired scores from the nurse and researcher for each subject. Concurrent Validity will be measured using comparison between the numeric rating scale and the behavioral pain scale on each subject at each time point. Construct validity will be measured by comparing the behavioral pain score before and after the interventional pain treatment.

For training purposes, the assigned nurse and research team member will be provided a copy of the "Chronic Pain Behavioral Pain Scale for Adults" chart to be utilized during their patient encounters. Each team member will be individually instructed in the use of the scale immediately preceding their first use of the scales. This training will include a discussion of the elements, the definition of behaviors, and the use of the scoring system.
