Zero in on Zero An Initiative to Improve Patient Access to Total Hip and Knee Arthroplasty: Focus on Quality and Safety

Introduction                       

A possible solution to our current national health care crisis is for providers, payers and policymakers to create and utilize transparent, consumer-driven care. If medicine is returned to its optimal focus - enabling health and providing effective care1 - then health care will improve for all stakeholders. A new quality and safety initiative created and deployed at the Good Samaritan Hospital (GSH) Orthopaedic Center of Excellence (OCE) is offered as an example of optimal focus in the conditions and care cycles of reconstructive surgery for patients with disabling arthritis of the hip and knee. This initiative is entitled “Zero in on Zero” (Zero).

Ten of the most crippling and expensive adverse events (AE) known to occur in patients with hip and knee arthroplasty were selected as targets for a zero rate of occurrence. Clinical practice guidelines (CPG) and best practice proposals (BPP) were discerned using best evidence literature.2,3 Each target was analyzed mirroring Root Cause Analysis (RCA)4,5 so that factors occurring before, during and after the adverse event(s) associated with hip and knee arthroplasty care cycles, could be thoroughly analyzed for future correction with CPG and BPPs. Essential to the success of the overall Zero initiative was collaboration of all stakeholders in the care cycles.

Reducing the rate of blood transfusions during and after total joint reconstruction of the hip and knee is offered as a stellar example of the initiative’s potential benefit. Prior to employing this particular BPP, the 17 surgeon rate was greater than 20%. After six months of the Zero initiative deployment, the rate was less than 2%. Similar reductions in AE rate were experienced in surgical site infections, poor pain management, patient dissatisfaction, poor discharge handoff, and venous thromboembolism (VTE). A total joint registry was created in order to track and measure care cycle details, including AEs.

Patient access will be a proxy for success in the Zero initiative because patients desire outcome transparency in health care; and their satisfaction with care will drive their selection of services. Additionally, patients acknowledge the quality of life benefits of hip and knee arthroplasty when they are encouraged by providers to select this type of care. They are also more likely to select total joint arthroplasty when they can be assured of optimal recovery and low rates of AE. The GSH OCE Zero initiative is an optimal solution to reduce AEs and increase patient access to total hip and knee arthroplasty.

Preparing         for         Excellence                  

The future of heath care around the world is threatened by variable patient access and poorly managed health care costs. Government mandates to control costs by severely reducing

payments to hospitals and providers will never effectively provide robust access to health care, nor will it successfully manage costs in any society burdened by aging and unhealthy populations. However, a vigorous reduction in adverse events, as in care cycles like total hip and knee arthroplasty, holds great promise to benefit all stakeholders in health care. Patient satisfaction is inexorably linked to value, safety, and consumer-driven strategies like: transparency,6 consumer-friendly providers, consumer-friendly payers, and consumer-friendly policy makers.7 Avoidance of adverse events will help protect patients and leveraged societal resources.8,9 Patient safety works for everyone in health care, and it is cost effective! Physician leadership is critical to success in the future of health care. Enabling health and providing effective treatment are the principles goals worthy of pursuit. The principles strategies to achieve these goals are: providing value for patients, organizing care around conditions and care cycles, and risk-adjusted results and costs.1 In our efforts to build and succeed with the Zero initiative for total hip and knee arthroplasty, we postulated that value for patients could be rapidly assisted by radically reducing adverse events and patient dissatisfaction. The conditions of disabling arthritis of the hip and knee and correction with total joint arthroplasty serve as ideal organizational models since results are rapidly achieved and most significant AEs occur relatively early in the care cycle. A total joint registry is one of the best ways to measure results and track costs, if set up with appropriate data fields

integrated with hospital data systems.10

 

Total Hip Arthroplasty

 

Zero in on Zero: A Step in the Right Direction

 

A year after our institution began the quest to achieve Joint Commission certification as a center of excellence in total hip and knee arthroplasty, we proposed the Zero initiative. Since clinical care is a process addressing disease before, during and after its assault on human health, it seemed appropriate to organize the Zero initiative around ten known costly and potentially crippling adverse events and processes in total hip and knee arthroplasty (Flow chart 43.1). We expected, and later realized, that the Joint Commission would recognize the nationally significant nature of our AE reduction initiative. See the Zero chart for the full listing of AE reduction targets and improvement strategies.

The next step was to review our institutional data for occurrence rates in the ten Zero areas. Where that data was not known, such is often the case in health care without clinical registries, national rates were listed [e.g., Medicare population rates for periprosthetic joint infection (PJI)]. The occurrence rate targets were then set with an ultimate goal of zero per

cent. It is clear that a zero rate of AE occurrence will never be consistently achieved, but any movement in that direction will produce benefits for all stakeholders in health care. Finally, available clinical practice guidelines (CPG) were acknowledged, and best practice proposals (BPP) were developed using best evidence literature.

Zero in on Zero

 

Since physician leadership is so critical to success in health care and institutional performance, we early appreciated that BPP deployment would require physician development and continuous review. We also supported the responsibility of every physician to pre-empt BPPs if a given patient situation required different strategies. Deployment strategies were listed in order to transparently engage center of excellence physicians, as well as challenge us all to collaborate in the beginning and throughout the years of ever improving total hip and knee reconstructive care.

 

DEPLOYMENT STRATEGIES

  1. Simple three step process: contributing factors before, during, and after total hip and knee arthroplasty.

  2. Research and analyze EBM literature, where available, emphasizing the highest level of evidence found in randomized clinical trials, controlled clinical trials, meta-analyses, and Cochrane reviews.

  3. Assign the literature to one or more of the three step process. Draw from the references included in the “Zero...” chart.

  4. Propose simple protocols to improve outcomes in each of the ten “Zero...” categories.

  5. Collaborate and achieve consensus with the total joint docs starting first with the Orthopaedic Service Council (OSC) and Orthopaedic Center of Excellence (OCE) groups. Also achieve multidisciplinary consensus.

  6. Publish and provide simple protocols to all stakeholders.

  7. Present protocols to Section for approval.

  8. Obtain administrative support when costs of deployment are significant.

  9. When needed, design and execute a formal CQI process.

  10. Use the registry for essential data collection and cost analysis.

  11. Report data up the institutional leadership levels as soon as valid.

The first AE reduction target we pursued was reducing allogeneic transfusions. These are associated with increased rates of PJI, all-cause death, and 30-day readmissions. Our institution had also embarked on a system wide effort to reduce all blood transfusions. See charts B and C for the methods we employed to define the RCA process, embed literature, and then formalize the BPP. We were pleased to observe a greater than 90% reduction in the rate of allogeneic transfusion within six months of deploying this particular BPP. For some surgeons (author) the rate is less than 0.5% for all hip and knee reconstructive surgeries. Key strategies were detecting all patients with a pre-operative hemoglobin of less an 13 gm and correcting with erythropoietin, the use of pre-operative tranexamic acid, avoidance of deep wound drains when feasible, and modified transfusion triggers. The GSH institution highly regards how orthopaedic surgeons from various unrelated practices, hospital administrators and staff, and patients and their families collaborated to achieve such rapid

success. Additionally, transfusion cost reductions exceeded 50 percent in the first six months after deployment. As of this publication, similar successes are documented in avoidance of PJI, high patient satisfaction, avoidance of VTE deaths in during and 30 days after hospitalization, optimal discharge handoff, and effective post-operative pain management. Zero really works!

Concluding                    Remarks                   

By 2016, the United States will likely experience total joint surgical shortfalls of between

18.6 to 69.4 percent.11 This will result from ever increasing end-stage hip and knee arthritis disease burden, and from a flat growth rate of surgeons capable of and committed to performing total hip and knee arthroplasty. There is no reason to believe to that delaying the timing of necessary total hip and knee arthroplasty will support optimal patient outcomes. In fact, just the opposite decline in benefit has already been observed.12

We predict a crisis in access to total hip and knee arthroplasty, and to revision arthroplasty. There will be three principle driving forces to limit access. First, patients themselves limit access by assuming that joint pain and decreased function are the natural results of aging.13 Second, primary care physicians who provide first contact care infrequently recommend total joint reconstruction. Patients are negatively influenced by this like of timely referral.14 Finally, patients choose to avoid access if they are fearful of difficult recovery, AEs, and burdensome costs.15

We recommend the Zero initiative as part of a regional, if not national solution to future patient access crises. It can provide stellar safety and quality for patients, providers, and policymakers—a “win-win” for all. Physician leadership is critical to create and sustain patient-centered solutions for adverse event and related cost challenges in hip and knee reconstructive surgery.
