[Clinical study PEPCA : The effect of standardized preoperative patient education for patient-controlled regional analgesia on postoperative pain].
Trial report in Schmerz (Berlin, Germany), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatient-controlled analgesia (PCA) is a well-established form of postoperative pain management. One form of administration is patient-controlled regional analgesia (PCRA), where local anesthetics are administered via peripheral regional catheters; however, a prerequisite is that the patients are instructed on its use. A multitude of sources recommend that these instructions are given before surgery as preoperative training on pain management procedures has been shown to significantly reduce patients' postoperative pain and increase their well-being.
objectiveThe aim was to assess the effect of guideline-assisted preoperative patient education for PCRA on postoperative pain in patients undergoing orthopedic surgery compared to unstructured postoperative standard instructions. MATERIAL AND
methodsA controlled study with two randomized samples and a postinterventional survey was conducted. Overall, 73 patients with PCRA catheters for orthopedic surgery were enrolled in the study. The 37 participants in the interventional group (IG) received guideline-based structured instructions on PCRA use as well as a handout immediately before the surgical intervention. The 36 patients in the control group (CG) received postoperative instructions in the anesthesia recovery room. Pain was documented according to the numerical rating scale (NRS) at 2h (t1), 6h (t2), and 24h (t3) after surgery.
resultsThere were no statistically significant differences in the average pain scores between the two groups; however, there were lower mean pain scores in the IG at t1 and t3.
conclusionA significant reduction of pain in the IG could not be shown. Further studies concerning this topic with larger samples and adapted points in time are recommended.
