Reverse Total Shoulder Arthroplasty in Patients Who Exceeded Their Life-expectancy: a Retrospective Study

Study Overview
=================
Brief Summary
-----------------
Reverse total shoulder arthroplasty (RTSA) has become an established treatment for cuff arthropathy, severe osteoarthritis and in certain fracture cases. Due to the increasingly aging population, patients who have already exceeded their life-expectancy pose a significant challenge to the shoulder surgeon. Therefore, we wanted to investigate patient demographics, hospital stay length, complication rate functional outcome, patient reported outcome scores and mortality retrospectively for patients, who were older than 83 years at time of implantation of a RTSA.

Detailed Description
-----------------
This is a retrospective single institution study. All patients older than 83 years who received a reverse shoulder arthroplasty from 2008 until 2019 are included. Elective cases are compared to fracture cases (patient demographics, length of hospital stay, complication rate, functional outcome, patient reported outcome scores and mortality).

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient reported outcome score: ASES | American Shoulder and Elbow Society (ASES) Score | until august 2020 | 
| Complication rate | postoperative complications requiring surgical intervention | until august 2020 | 
| Quality adjusted life year (QALY) | The quality adjusted life year (QALY) ) is a well-established indicator of the life quality for the remaining years and was calculated as the years of life following the operation, multiplied by the utility value, for the current study, defined as the postoperative American Shoulder and Elbow Surgeons Shoulder Score (ASES) score (0-1 points) at last follow-up. | until august 2020 | 
| Mortality | Survivership | until august 2020 | 
| Patient reported outcome score: QuickDASH | Quick Disabilities of the arm, shoulder and hand (DASH) Score, | until august 2020 | 
| Patient reported outcome score: VAS | Visual analog score (VAS) | until august 2020 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient demographics | male/female ratio, age, BMI, ASA (American Society of Anesthesiologists) classification, hospital stay length, range of motion | at time of surgery |
