The top line full year results were in line with the $7.1 billion forecast issued by the company last fall and EPS was at the high end of $1.55 to $1.70 guidance.

Overall, sales grew 40.8% year over year in 2015 and adjusted EPS improved by 12.5%, mostly due to the acquisition of Gentiva Health and Centerre Healthcare Corporation.

Now what: Strengthening tailwinds tied to rehabilitation and long-term care demand from aging Americans remains the biggest reason to consider owning Kindred Healthcare shares, but tailwinds are slightly offset by lackluster performance at the company's hospital segment and regulatory reimbursement hurdles.

Revenue in the home division increased 4.8%, rehab sales grew 4.8%, and revenue in the nursing center segment inched up 0.6% versus last year, but same-hospital revenue slipped 3.3% from the year before because of a drop in admissions.

For this year, management expects similar single digit growth in sales to between $7.2 billion and $7.3 billion, but adjusted EPS is expected to drop to about $1.25 as the company transitions to long-term acute care criteria that will result in a drop in reimbursement rates for some patients.

The reimbursement drag on EPS could be somewhat offset by cost savings associated with its previous merger and acquisition activity and management says that expense reductions are running ahead of pre-deal expectations. If that continues, then Kindred Healthcare's cash flow should give it plenty of financial firepower to support its healthy 5.33% dividend yield and for that reason, long-term income investors might want to consider owning this company's shares.
