Form of Letter to General Public

Dear:

It is my pleasure to share the enclosed copy of Kindred’s 2010 Quality and Social Responsibility Report that highlights the quality care and services we deliver to 33,800 patients and residents daily by nearly 57,000 dedicated employees in 696 sites of service nationwide. This report and our performance illustrates Kindred’s committed to being transparent about our quality results and our ongoing efforts to ongoing efforts to improve person-centered care coordination, transitions in care and advancing the policy goal of continuing the care in a more integrated, cost-effective way. Delivering quality post-acute care services has been and always will be our number one priority.

We are proud that we have been ranked one of Fortune magazine’s Most Admired Healthcare Companies in 2009, 2010 and 2011. We take seriously our responsibility to educate the public and policymakers about our challenges, our successes, the changing nature of our patient and resident population and how we care for them and areas for improvement that we are addressing.

As the report illustrates, in 2010 we built upon our quality improvements of the past several years, consistently provided high quality care and customer service outcomes.

Here are just a few quick highlights from the report that illustrate how we delivered on Kindred’s promise of hope, healing and recovery:

   

Our long-term acute care hospitals and nursing and rehabilitation centers continued to outperform national benchmarks in key quality indicators while caring for sicker patients and investing in additional clinical resources to meet their needs.

   

Our integrated care approach resulted in decreased lengths of stay, fewer rehospitalizations and more patients going home sooner.

   

The physical, occupational and speech therapy services provided by Peoplefirst led to a 76.4% functional improvement for our patients.

   

In 2010, we invested more than $300 million in our employees through training, healthcare, tuition reimbursement and other programs.

The 2010 report also features a new section on Powering Innovation. On pages 18 and 19, we detail how Kindred is leading efforts to (1) better integrate care across the post-acute care continuum to improve clinical outcomes and care coordination, (2) is working to successfully transition people home through an episode of care sooner, and (3) reduce avoidable and costly rehospitalizations to short term acute care hospitals. Part of our approach to innovations in care was the development of our annual Clinical Impact Symposia, which brings together over 400 clinicians from around the U.S. to improve the clinical practice of our physicians, therapists, nurses and other caregivers to advance Kindred as a leader in clinical excellence.

Recently we announced plans to acquire RehabCare Group, which will better enable us to Continue the Care for patients and residents across the entire post-acute continuum in local markets. This growth and development is possible because of our dedicated employees and a balanced approach to creating value for our patients, residents, employees and stakeholders.


Thank you for taking the time to review this report. Please contact me with any questions or comments on our report.

Sincerely,

Paul Diaz
