Shares of DaVita HealthCare Partners (NYSE:DVA) look like they might need a little care following the release of the company's Q3 results. For the quarter, revenues totaled $2.1 billion, an improvement over the $1.8 billion the company posted in the same period the previous year. Attributable net income went in the opposite direction, however, coming in at $136.6 million ($0.64 per diluted share) versus the Q3 2012 result of $144.7 million ($0.75).

In terms of operations, the company provided its dialysis services to roughly 166,000 patients at 2,108 outpatient centers. During the quarter, it acquired 10 centers in the U.S. and 18 abroad. It opened a total of 25 such facilities throughout the U.S. during the period. 

DaVita also provided updated guidance for certain fiscal 2013 line items. Chiefly, it now expects operating income of $380 million to $400 million. That's a narrowing of the previously provided range, which was $380 million to $430 million. Operating income for this past Q3 was $377 million.

The company's stock dipped by 2.7%, or $1.51, today to close at $55.02.
