Case Responses

2 year delay in diagnosis and treatment of basal cell carcinoma, nodulo- infiltrative type on patient’s forehead. (Case #289)

  • Medical Probability: 6 / 10

  • Causation Probability: 3 / 10
  • Causation Summary: Would need to review case further in terms of the extent of surgery. Generally basal cell carcinomas can cause local issues; however, it is very rare for a basal cell carcinoma to spread to lymph nod...

Elective sigmoidectomy breakdown and death (Case #293)

  • Causation Probability: 6 / 10
  • Causation Summary: If there was opportunity to address the abdominal collections or a delay this could have prevented sepsis. Again would need to see all the records.

About Us

Kalivar represents a new concept in medical-legal consulting.

Kalivar was founded by two physicians and a lawyer who believe that the medical legal industry deserves an upgrade.

The current state of affairs:

  • Not infrequently doctors are unjustly accused of negligence. At the same time, malpractice victims do not always receive the compensation they deserve.
  • Many doctors are reluctant to serve as an expert witness and do not have time for extensive reviews of medical records. Choosing sides in a dispute between a patient and a peer may be uncomfortable, especially when doctors be deposed or required to provide testimony.
  • The few doctors who serve as expert witnesses often charge high fees to attorneys for an initial opinion. As a result, many attorneys, whether they are representing the plaintiff or the defendant, tend to rely on the opinion of a single expert as the foundation for their case. When that single initial opinion is questionable, significant funds are incurred unnecessarily in legal cases that should never have been initiated, or that instead should have settled immediately.

There is a better way.

We have created an on-line community where doctors can provide anonymous opinions on medical cases, and have the opportunity to be retained as an expert.

Kalivar allows doctors to provide unbiased opinions, as we do not disclose their identity, and we are unaware of whether an opinion is being requested by a defendant or a plaintiff. With only a short event summary to read, busy clinicians can find a few minutes during their day to leave a comment in our social media-like platform (and potentially be compensated for their time!).

Kalivar allows attorneys to obtain diverse opinions from different experts across multiple specialties, for very limited costs. Attorneys will have greater insight into a case before embarking on a long and expensive process that may be unnecessary to begin with.

We hope that you will help us improve the medical-legal industry and join the Kalivar community.

Thank you for your help!

The Kalivar Team: Mark, Paul, Meir
