There also are so many frivolous lawsuits. I believe that the plaintiffs should be required to pay for their own attorneys.  If plaintiffs lose a frivolous case, they should be responsible
to pay the defendants legal expenses.

Risk Management Ideas:

1. Regarding PVD: In this day and age where there are so many vascular doctors available, 
consider a timely referral to such a specialist
2. Regarding skin lesions: Consider using up to date diagnostic tools such as dermatoscopes with high polarization, wide fields, infection control techniques with the ability to attach to cameras on cell phones might all help avoid
potential malpractice claims.

I am not an attorney and each situation is different. The above are my own personal opinions.
