From Medical Economics (via KevinMD), a reminder of how doctors can get sued up one side of the street and then right back down the other (emphasis added):

Doctors who treat nursing home patients also face the risk of a suit alleging "elder abuse." If the patient's in pain, for example, a doctor who's overly cautious or overly generous about prescribing pain medication could be charged with elder abuse. "Every day," says [internist Steven] Reznick, "we see newspaper or TV ads by plaintiffs' attorneys seeking cases of nursing home neglect or abuse."
