Patient Satisfaction During Lomber Transforaminal Epidural Steroid Injection: The Role of Sedation, Anxiety, and Pain

Lumbar radicular pain is a common clinical problem that can substantially impair daily functioning and quality of life. Transforaminal epidural steroid injection (TFESI) is a minimally invasive procedure frequently used in the management of this condition.

In clinical practice, TFESI may provide pain relief, improve physical function, and in some patients reduce or delay the need for surgical intervention. However, its effectiveness is not uniform, and the magnitude and duration of benefit may vary across individuals. In some patients, symptom relief may be temporary, and recurrent pain may lead to repeat injection or surgical treatment. Published studies have also shown a wide range of treatment success rates, suggesting that patient-related and procedure-related factors may influence outcomes.

In this context, a more standardized evaluation of patient-reported outcomes after TFESI is needed. Pain intensity, anxiety level, and patient satisfaction are clinically relevant outcomes that may provide a more comprehensive understanding of the patient experience during and after the procedure. In particular, patient satisfaction may be influenced not only by postprocedural pain relief, but also by anxiety before or during the procedure, sedation status, procedural discomfort, and other clinical or demographic characteristics.

The aim of this prospective observational study is to quantitatively assess postprocedural pain, preprocedural anxiety, and patient satisfaction in patients undergoing lumbar TFESI, and to identify the clinical and demographic factors associated with patient satisfaction. The study is designed to reflect real-world clinical practice rather than protocol-driven intervention assignment.

A total of 120 participants who present to the pain medicine outpatient clinic of Mersin University Faculty of Medicine Hospital, who undergo lumbar TFESI, and who meet the inclusion and exclusion criteria will be enrolled after providing written informed consent. Demographic and baseline clinical data, including age, body mass index, primary diagnosis, comorbidities, pain intensity, and medical and surgical history, will be collected using a standardized data collection form.

Procedure-related assessments will also be documented in a standardized manner. Peak pain intensity during the procedure, measured using the Numeric Rating Scale (NRS), and pain intensity at 1 hour after the procedure will be recorded. Anxiety level will also be assessed and documented. Sedation status, fluoroscopy-related metrics, and intraprocedural events will be recorded. Patient satisfaction will be evaluated at 1 hour after the procedure using a Likert-based satisfaction questionnaire.

By analyzing patient-reported and procedure-related outcomes together, this study aims to provide a clearer understanding of the factors associated with patient satisfaction after lumbar TFESI. The findings may help support more individualized patient selection, improve periprocedural assessment, and contribute to better follow-up strategies in routine clinical practice.
