Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Most chronic pain patients have mood disorders. The mood disorders may improve with better analgesia produced by Ketamine injections. A prospective study of patients undergoing interventional pain therapy using Ketamine injections. Pre-injection and post-injection patient data is collected. Pain is measured using numeric pain rating scale, and change in pain score by 2-points is considered significant. Sleep is measured using Likert sleep scale, and change in sleep score by 2-points is considered significant. Anxiety is measured using general anxiety disorder (GAD-7) scale, and change in anxiety score by 4-points is considered significant. Depression is measured using patient health questionnaire (PHQ-9), and change in depression score by 5-points is considered significant.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic pain is usually associated with psychological and mood disorders. Many chronic pain patients have various forms of mood abnormalities; and these mood issues may improve with better analgesia produced by Ketamine injections.

This is a prospective observational study of consenting adult patients who are undergoing interventional pain management. The patients undergo routine interventional pain therapy using Ketamine injections. Pre-injection and post-injection patient data is collected using validated tools. Data collection includes patients' age, psychiatric diagnosis, pain score, sleep score, anxiety score and depression score.

Pain score is measured using the numeric pain rating scale, and a change in the pain score by 2-points is considered significant. Sleep score is measured using the Likert sleep scale, and a change in the sleep score by 2-points is considered significant. Anxiety is measured using the general anxiety disorder (GAD-7) scale, and a change in the anxiety score by 4-points is considered significant. Depression is measured using the patient health questionnaire (PHQ-9) scale, and a change in the depression score by 5-points is considered significant.

Data is analyzed with IBM® SPSS® Statistics 25; using Student's t-test, ANOVA, Pearson Chi-square test, and regression analysis. P-value \<0.05 is considered significant.
