Factors associated with improvement in quality of life and inpatient costs for ream and run and anatomic shoulder arthroplasty.

Drivers of lower inpatient hospital costs and greater improvements in health-related quality of life for patients undergoing total shoulder and ream-and-run arthroplasty

These authors sought to determine patient-level drivers of lower costs and improved health-related quality of life (HRQoL) in 2 anatomic shoulder arthroplasty procedures:  ream-and-run arthroplasty (RnR N=211) and anatomic total shoulder arthroplasty (aTSA N=222).

As can be seen from the below, there were important differences in the patients having the two procedures, including sex, age, BMI, ASA class, insurance, diagnosis, glenoid type, prior surgery, opioid use, diabetes, preoperative simple shoulder test scores, and preoperative physical and mental function,

The preoperative and postoperative scores for the two procedures are shown below,

The cost, utility and QALY data for the two procedures are shown below,

In the aTSA group, female sex, lower American Society of Anesthesiologists class, diagnosis other than capsulorrhaphy arthropathy, lower pain score, and higher Single Assessment Numeric Evaluation score were associated with decreased total hospitalization costs; in addition, female sex was an independent predictor of lower total costs. 

Insurance other than workers’ compensation, a diagnosis of chondrolysis, and higher optimism led to greater QALY gains, but a diagnosis of capsulorrhaphy arthropathy was the only independent predictor of greater QALY gains with aTSA

In the ream-and-run arthroplasty group, older age, lower body mass index (BMI), lower American Society of Anesthesiologists class, insurance other than Medicaid, diagnosis other than capsulorrhaphy arthropathy, no history of surgery, higher preoperative Simple Shoulder Test score, and higher preoperative Short Form 36 Physical Component Summary score were associated with lower total costs; moreover, lower BMI was an independent predictor of lower costs. 

Higher preoperative optimism was an independent predictor of greater QALY gains with the RnR.

This study identified fixed (sex and diagnosis) and modifiable (BMI) factors that drive decreased hospitalization costs and increased HRQoL improvements in shoulder arthroplasty patients. Higher preoperative patient optimism was a consistent predictor of improved HRQoL for both TSA patients and ream-and-run arthroplasty patients.

Comment: This large single-center study assessed the factors associated with inpatient costs and quality of life for patients having two types of anatomic shoulder arthroplasty: total shoulder and ream and run. It is evident that the two patient populations differ in substantial ways, so this study does not compare costs and QALYs for the two procedures when applied to comparable patients. It does, however provide useful data for the important drivers of cost and QALY within in group. Important, it calls attention to the importance of the patient's preoperative optimism as a driving factor for improvement in the quality of life. For the optimism score, the patient simply indicated his or her optimism for a positive outcome from surgery on a 0 to 10 scale, on which 10 was maximally optimistic.

Total shoulder and ream and run: the importance of patient optimism.

Drivers of Lower Inpatient Hospital Costs and Greater Improvements in Health-Related Quality of Life for Patients Undergoing Total Shoulder and Ream-and-Run Arthroplasty

These authors sought to determine the patient factors associated with lower costs and improved health-related quality of life (HRQoL) in two anatomic shoulder arthroplasty procedures – total shoulder arthroplasty (TSA, n=222) and ream-and-run arthroplasty (n=211).

For the optimism score, the patient indicated his or her optimism for a positive outcome from surgery on a 0 to 10 scale, on which 10 was maximally optimistic.

In the TSA group, total hospital costs were lower for female sex, lower ASA score, diagnoses other than capsulorrhaphy arthropathy, lower pain scores, and higher SANE scores. Female sex was an independent predictor of lower total costs. 

Greater QALY gains were associated with insurance other than worker’s compensation, diagnosis of chondrolysis, and higher optimism. A diagnosis of capsulorrhaphy arthropathy was the only independent predictor of greater QALY gains. 

In the ream-and-run group, lower total costs were associated with older age, lower BMI, lower ASA score, insurance other than Medicaid, diagnoses other than capsulorrhaphy arthropathy, no history of previous surgery, higher preoperative SST scores, and higher preoperative SF-36 physical component summary scores were associated with lower total costs. Lower BMI was an independent predictor of lower costs. 

Greater QALY gains were independently associated with higher preoperative optimism.

Comment: This study is important in that it identifies factors associated with lower costs and greater improvements in quality of live. Of particular interest is the predictive value of a simple assessment of the patient's preoperative optimism.

The really interesting questions are (1) whether optimism should be considered in decision making and (2) whether preoperative optimism is a modifiable factor.

Total Shoulder Arthroplasty - how valuable is it?

Patient-Reported Outcome Measures and Health-Related Quality-of-Life Scores of Patients Undergoing Anatomic Total Shoulder Arthroplasty

These authors analyzed 92 patients with glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty performed by an individual surgeon using a a press-fit, short-stem anatomic humeral component and a hybrid, all-polyethylene, pegged glenoid implant and that had 1-year follow-up with respect to their health-related quality-of-life (HRQoL) scores and patient-reported outcome measures (PROMs): Disabilities of the Arm, Shoulder and Hand (DASH) score, the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST), and a visual analog scale (VAS) for shoulder pain and function.

There were significant improvements in all PROMs and HRQoL scores (p < 0.001) at 1 year after the surgical procedure.

The changes in VAS QoL (very weak to moderate), EQ-5D (weak), and SF-6D (weak) were significantly correlated (p < 0.05) with the changes in PROMs, demonstrating comparably acceptable validity. 

 There were large effect sizes in the VAS QoL (1.843), EQ-5D (1.186), and SF-6D (1.084) and large standardized response mean values in the VAS QoL (1.622), EQ-5D (1.230), and SF-6D (1.083), demonstrating responsiveness. The effect sizes of all PROMs were larger than those of the HRQoL scores.

Comment: In this well-done study, the authors point out that shoulder patient reported outcome metrics cannot be used in an analysis of comparative value of shoulder arthroplasty relative to other orthopaedic and nonorthopaedic conditions. 

Measurement of quality-adjusted life-years (QALYs a summary measure of health outcome that combines the impact of a treatment on a patient’s length of life) and health-related quality of life (HRQoL) can be used to compare alternative treatments of a specific condition, as well as treatments of disparate conditions. QALYs can be used with costs (direct and indirect) to determine cost utility (monetary cost/QALY), which can be used to perform cost utility analysis to compare, say a total shoulder to a rhinoplasty. 

It is not surprising to see a lack of tight correlation between patient reported outcome metrics and measures of health-related quality of life measures: they do not measure the same thing. The PROMS are used to measure the change in patient-assessed shoulder comfort and function. In this study the SST changed from 3 preoperatively to 10 postoperatively. This is exactly the same change documented in many different case series by different surgeons using different makes of implants. It is very reassuring to see consistently large effect sizes for the PROMs.

On the other hand, one could expect the HRQoL to have a strong correlation with the SST only if the shoulder operated on was the only factor affecting the patients health-related quality of life. Consider the patient who has a SST 3=>10 after a shoulder arthroplasty, but who at one year comes in  saying "now my other shoulder (or my hip or my knee or my back)  is killing me" or "I fell and broke my wrist" or "I now have cancer or ....". This is why the effect sizes are smaller for the HRQoL than for the PROM.

As shoulder surgeons we are responsible for an important, but only one part of a patient's health equation. The measure of our success is the value of our treatment, that is the benefit the patient realizes from our intervention divided by the cost of our evaluation and treatment (i.e. change in SST decided by the sum of preoperative imaging, implants, hospital costs, professional fees, rehabilitation and complications). In that the numerator seems pretty standard, optimization of this quotient is most effected by the denominator.

Cost-effectiveness and health-care value analysis - the elephant in the room

Patient-Reported Outcome Measures and Health-Related Quality-of-Life Scores of Patients Undergoing Anatomic Total Shoulder Arthroplasty

These authors evaluated Health-related quality-of-life (HRQoL) scores and patient-reported outcome measures (PROMs) in 93 patients at year after anatomic shoulder arthroplasty for advanced glenohumeral osteoarthritis to establish values of HRQoL scores that can be used for cost effectiveness and value analysis and to assess relationships between HRQoL scores and shoulder and upper-extremity PROMs. 

Preoperative and postoperative functional outcomes were assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) score, the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST), and a visual analog scale (VAS) for shoulder pain and function. Health utility was assessed with the EuroQol-5 Dimensions (EQ-5D), Short Form-6 Dimensions (SF-6D), and VAS Quality of Life (VAS QoL). 

There were significant improvements in all PROMs and HRQoL scores (p < 0.001) at 1 year after the surgical procedure. 

Each of the metrics showed a large effect size and standardized response mean

The changes in VAS QoL and EQ-5D were significantly correlated with the changes in most PROMs, but the correlation was only weak to moderate.

The authors concluded that PROMs and HRQoL scores are not interchangeable, and studies of the cost-effectiveness and value of shoulder arthroplasty should incorporate both shoulder and upper-extremity PROMs and HRQoL scores. 

Comment: The value of a treatment is defined as the benefit to the patient divided by the cost of rendering that treatment. This article demonstrates that we have robust tools for evaluating the benefit to the patient of shoulder arthroplasty, both with respect to the improvement in patient self-assessed comfort and function (PROMS) and in the quality of life (HRQoL).

For determining the cost-effectiveness and value of treatment, the challenge is the difficulty in measuring the cost of care, the denominator of the value equation.

One recent study demonstrated the complexity of this assessment: Preparing for the bundled-payment initiative: the cost and clinical outcomes of total shoulder arthroplasty for the surgical treatment of glenohumeral arthritis at an average 4-year follow-up

The pre-hospitalization, hospitalization, and posthospitalization periods accounted for 3.5%, 88.4%, and 8.1% of the 4-year total cost of TSA, respectively. Within the pre-hospitalization period, the shoulder computed tomography scan was the most expensive component of care (37% of pre-hospitalization cost). During the hospitalization period, as well as during the entire 4-year study period, the operating room was the most expensive area (81% of hospitalization cost and 71% of total cost). Within the operating room, the implants were the single most expensive component of care (43% of hospitalization cost and 38% of total cost). The surgeon’s fee was $1,470 and was responsible for 8% of total cost. In the post-hospitalization period, home health care was the most expensive component of care (70% of post-hospitalization cost).

What emerges from that study is that 38% of the total cost is the cost of the implants used.

In a recent article, An analysis of costs associated with shoulder arthroplasty, the authors pointed out that the implant brand was a major factor the the cost of shoulder arthroplasty, however, as they stated "Because actual implant costs were the result of confidential contractual negotiations, actual dollar amounts could not be published nor could the brand names be published adjacent to their relative costs."

The most modifiable variable in the value of shoulder arthroplasty is the cost of the implant, yet because of the confidentiality of contract negotiations, the actual cost data are not available for analysis. We are aware of a major medical center that requires that implant vendors offer implant charges that are at the 25th percentile of the charges across the country. This means that, all other things being equal, the value of shoulder arthroplasty at that medical center would be substantially higher than average because their costs are less.

We conclude that we have a good tool-set for measuring the effectiveness of shoulder arthroplasty, but as a specialty, we do not have a meaningful way of measuring the cost of providing this procedure, especially with respect to implant costs, the elephant in the room.

Health-related quality of life and functionality after reverse shoulder arthroplasty

Health-related quality of life and functionality after reverse shoulder arthroplasty

This is a report of 80 patients having had a reverse total shoulder for either primary osteoarthritis, massive rotator cuff tear, or cuff tear arthropathy. At a mean 5-year follow-up, the cumulative survival rate was 97.3% and there were significant improvements in the Constant score and range of motion when compared with the baseline values. The Constant score was 93.2% of the sex- and age-matched normal values and the postoperative SF-36 scores showed no significant differences compared with normative data. Younger patients and subjects with worse preoperative conditions achieved the greatest benefit after RSA.

The length of follow-up was found to be associated with the severity of scapular notching. The complications included two dislocations, one infection and one hematoma.

These are among the best results to be reported for reverse total shoulder. This may be due to the fact that all surgeries were performed by the same surgeon and that patients were excluded if they had a prior arthroplasty,  proximal humeral fracture, fracture sequelae, rheumatoid arthritis, tumors, evidence of an active infection, allergic reactions to metal implants, alcohol abuse, a predicted survival of less than 6 months, a patient’s unwillingness to cooperate, or legal incapacitation. It is also of note that the preoperative diagnoses included more benign diagnoses that those of many series: patients had a diagnosis of either irreparable massive rotator cuff tear (43%), cuff tear arthropathy (16%), or primary glenohumeral OA (41%).  Patient age was 72.5 5.0 years (range, 61-86 years). Average preoperative active flexion was 100 degrees (range 50 - 150 degrees). 

It seems that few of these patients met what used to be considered to be the 'classical' indications for a reverse total shoulder: pseudo paralysis or anterosuperior escape.
