The number of facebook likes can be an indication of the quality of the health organisation and patient satisfaction.

Researchers compared the 30-day mortality rates and hospital patron recommendations to the number of "Likes" on the hospitals' Facebook pages from 40 hospitals near New York, NY. They found that Facebook "Likes" were positively associated with patient recommendations and that a one percentage point decrease in the 30-day mortality rate corresponded with almost 93 more Facebook "Likes."In addition to these findings, the researchers also found that teaching hospitals had a lower number of Facebook "Likes" than traditional hospitals, despite the fact that the staff at teaching hospitals is younger and predicted to be more active on Facebook.
The researchers noted that this negative association of "Likes" and teaching hospitals may be a reflection of quality issues at those hospitals. "Any hospital can start a Facebook page, but those with higher levels of quality and patient satisfaction are more likely to attract "Likes" to their page" wrote the authors. "Public health researchers and hospitals can use facebook "Likes" as a proxy for hospital quality and patient satisfaction."
