Rotator Cuff Pathway

Study Overview
=================
Brief Summary
-----------------
Rotator cuff surgery is mostly performed on an outpatient basis, and many patients still experience moderate to severe pain after surgery, despite the use of regional anesthesia and opioids. The specific aim is to determine whether a comprehensive pathway that includes a well-defined regional technique and multimodal analgesia will reduce the worst pain with movement 0-48 hours after block placement compared to the current standard practice. This is a 'before and after' study. We plan to have 70 patients studied prior to initiation of a pathway, and 70 patients studied after initiation of a pathway. Both groups will receive identical postoperative follow-up.

Detailed Description
-----------------
Previous study in shoulder arthroplasty patients demonstrated low pain scores and minimal intravenous opioid use when utilizing a clinical pathway that included peripheral nerve block and preemptive non-opioid analgesia (Goon et al. 2014). These surgeries were done as inpatient and patients had availability of intravenous opioids. Assessment of the current approach to managing rotator cuff repairs demonstrated an average worst pain score after surgery of 7.0, SD 2.1 (Kahn) which is often categorized as severe pain. Given that most rotator cuff repairs are done as outpatients, it is important to develop a clinical pathway that mitigates the worst pain experienced after surgery. With outpatient surgery, there are obvious limitations regarding availability of rescue pain medications. Therefore, the pathway needs to emphasize patient education and strategies to reduce the pain as peripheral nerve block subsides. Given these issues, we believe there is an advantage to prolonging the analgesia from the nerve block (Rosenfeld et al. 2016, Yadeau et al. 2016, Kahn) and educating patients regarding the importance of preemptive analgesia and when to take opioid medications. This study will evaluate whether the clinical pathway might mitigate the worst pain after surgery that occurs with the current standard practice.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Primary Outcome - Worst NRS With Movement | worst NRS with movement. A lower score is a better outcome. The score range is between 0 and 10. | 0-48 hours after block placement | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Opioid Use | The total opioid consumption measured in morphine milligram equivalents (MME). Although recorded at different time points, the total MME per patient was calculated. | Post Op Days 1,2,7,14 | 
| Patient Satisfaction With Pain Management | Measures the patient's satisfaction with their pain management on a scale of 0-10. A higher score is a better outcome. | Post Op Days 1,2,7,14 | 
| Pain Score at Rest | a NRS score on a scale from 0 to 10. 0 means no pain and 10 is the worst pain imaginable. A lower score is a better outcome. | Post Op Days 1,2,7,14 | 
| Block Duration | Measures the duration of the block from: the time the block started to the time the block completely wore off the time the block started to the time the patient first noticed pain the time the block started to the time the patient felt normal sensation | Through Post Op Day 2 |
