The goal of this observational study is to learn about the effectiveness of different locoregional anesthesia techniques, particularly the Quadro-Iliac Plane (QIP) block, in patients undergoing hip surgery, including arthroplasty. The main question it aims to answer is:
Does the QIP block improve postoperative recovery and pain control compared to other routinely used locoregional anesthesia techniques in patients undergoing hip surgery?
Participants undergoing hip surgery as part of their standard clinical care will receive one of the locoregional anesthesia techniques already in use at the hospital (including QIP block, fascia iliaca block, PENG block, or others, according to anesthesiologist choice). Postoperative outcomes will be collected prospectively, including quality of recovery (QoR-15 at 24 hours), pain scores at rest and during movement at predefined time points up to 48 hours, analgesic consumption, time to first analgesic request, time to mobilization, and occurrence of complications.

Primary outcome measure(s)
Quality of Recovery (QoR)-15 score — 24 hours postoperatively The Quality of Recovery-15 (QoR-15) is a validated patient-reported outcome measure designed to assess the quality of postoperative recovery across multiple dimensions of physical and psychological well-being.
The questionnaire consists of 15 items, each scored on an 11-point numerical scale, resulting in a total score ranging from:
Minimum score: 0 → extremely poor quality of recovery Maximum score: 150 → excellent quality of recovery
Higher QoR-15 scores indicate a better postoperative recovery experience.
The questionnaire evaluates five key domains:
Pain Physical comfort Physical independence Psychological support Emotional state
