Clinical and Economic Evaluation of Point-of-care Ultrasound-guided Infiltration for Subacromial and Carpal Tunnel Syndromes in Primary Care: a Cluster-randomized Study Protocol. (Q-EPICAP)
The aim of this clinical trial is to determine whether point-of-care ultrasound-guided corticosteroid injection is more effective than conventional injection guided by anatomical landmarks or standard oral medication for patients with upper-extremity conditions (subacromial impingement syndrome [SAS] or carpal tunnel syndrome [CTS]) in primary care.
The main questions this study seeks to answer are:
Does ultrasound-guided injection provide superior long-term pain relief compared to blind anatomical injection and oral medication?
Does ultrasound-guided injection lead to better functional recovery and improved health-related quality of life in patients?
Is ultrasound-guided injection a cost-effective strategy from both the healthcare system and societal perspectives (including reducing sick leave)?
This study represents the quantitative phase of the mixed-methods Q-EPICAP study. Researchers will compare three parallel groups across 23 primary care centers to determine the most effective and efficient treatment strategy.
Participants will:
Receive one of three assigned treatments: blind anatomical infiltration (Group I), ultrasound-guided infiltration (Group UI), or standard oral drug therapy (Group P).
Attend follow-up assessments at baseline and at 15, 30, 90, and 180 days after the initial intervention.
Complete questionnaires to assess pain intensity (Visual Analog Scale), upper limb function (ASES or Boston Disability Assessment Questionnaire), and quality of life (EQ-5D-5L).
Provide data on medical resource utilization and sick leave to assess socioeconomic costs.

详细说明
Upper extremity pathologies, particularly subacromial impingement syndrome (SAS) and carpal tunnel syndrome (CTS), represent a significant clinical and socioeconomic burden for primary care systems, primarily due to functional disability and prolonged sick leave.
Although corticosteroid injections are frequently used, traditional blind injections guided by anatomical landmarks often lack anatomical precision. Point-of-care ultrasound-guided injections offer greater accuracy and better short-term clinical outcomes; however, their cost-effectiveness in routine clinical practice has not yet been adequately assessed.
This pragmatic, prospective, multicenter, cluster-randomized clinical trial includes 23 participating primary care centers (clusters) in Lleida, Spain, with a 6-month longitudinal follow-up. This study constitutes the quantitative phase of the mixed-methods Q-EPICAP project.
A total of 225 adult patients diagnosed with SAS or CTS and presenting with baseline pain (VAS ≥ 3) were divided into three parallel groups:
- Group I: Anatomical landmark-guided infiltration.
- Group UI: Ultrasound-guided infiltration performed by family physicians.
- Group P: Standard oral pharmacological treatment.
Data collection was performed at baseline and at 15, 30, 90, and 180 days post-intervention. The primary outcome measure was pain intensity (VAS). Secondary outcomes included upper limb function (ASES and Boston questionnaires), health-related quality of life (EQ-5D-5L), and a comprehensive economic evaluation (cost-effectiveness and cost-utility indices) that integrates the perspectives of healthcare systems and society.

有源比较器：Standard Oral Treatment
Patients in this cohort are treated exclusively with standard systemic oral drug treatment of routine clinical practice and physiotherapy recommendations according to established clinical guidelines, without receiving local procedures.
|
Prescription of systemic oral pharmacological treatment according to standard clinical practice and guidelines, which may include individual or combined use of the following therapies, or no pharmacological prescription if deemed appropriate by the clinician:

有源比较器：Conventional Infiltration
Patients in this cohort receive a corticosteroid infiltration, blinded to anatomical landmarks, for subacromial impingement syndrome or carpal tunnel syndrome, administered by primary care physicians following standard clinical practice.
|
Local infiltration consisting of a combination of a corticosteroid and a local anesthetic, administered in a 1:1 volume ratio (1 ml + 1 ml, total volume 2 ml):
In the Conventional Infiltration group, the solution is injected using the standard anatomical landmark technique (blind technique). |

Change from Baseline in Pain Intensity using the Visual Analog Scale (VAS)
大体时间：Baseline (Day 0), 3 months, 6 months, and 9 months post-intervention.
|
Pain intensity will be assessed using the Visual Analog Scale (VAS), where patients rate their pain on a line from 0 (no pain) to 10 (worst possible pain).
The primary endpoint is the change in the score from baseline to 3, 6, and 9 months.
Higher scores indicate greater pain intensity.

Change from Baseline in Shoulder Function using the American Shoulder and Elbow Surgeons (ASES) Score
大体时间：Baseline (Day 0), 3, 6, and 9 months post-intervention.
|
The ASES score evaluates shoulder pain and activities of daily living.
It consists of a patient-reported section (10 items) and a clinical assessment.
The total score ranges from 0 to 100, where 100 indicates better shoulder function and less pain.
We will assess the change in this score relative to baseline.

Change from Baseline in Carpal Tunnel Symptoms and Function using the Boston Carpal Tunnel Questionnaire (BCTQ)
大体时间：Baseline (Day 0), 3, 6, and 9 months post-intervention.
|
The BCTQ consists of two scales: the Symptom Severity Scale (11 items) and the Functional Status Scale (8 items).
Each item is scored from 1 (mildest) to 5 (most severe).
The final score is the average of the responses.
Higher scores indicate more severe symptoms and greater functional impairment.

Change from Baseline in Health-Related Quality of Life (EQ-5D-5L)
大体时间：Baseline (Day 0), 3, 6, and 9 months post-intervention.
|
The EQ-5D-5L questionnaire assesses 5 dimensions of health (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) across 5 levels of severity.
It also includes a Visual Analog Scale (EQ-VAS) from 0 (worst imaginable health) to 100 (best imaginable health).
Higher index values and VAS scores represent better health status.
