John G. Hoffmann, M.D., Disciplined for Unprofessional Conduct

Stephen Barrett, M.D.
April 4, 2020

In 2015, the Wisconsin Medical Examining Board concluded that John G. Hoffmann, M.D., had endangered a patient by failing to properly monitor antibiotics he had prescribed for “chronic Lyme disease” and an antifungal drug he had prescribed for “abdominal candidiasis.” Hoffmann is part of a small network of so-called “Lyme literate doctors” who attribute a multitude of common symptoms to “chronic Lyme disease,”which they assert should be treated with many weeks or months of intravenous antibiotic treatment. The scientific medical community rejects these concepts. The board ‘s order (shown below), to which Hoffmann consented, said that if he wants to treat any patient for Lyme disease, he must follow FDA guidelines. He was also ordered to take 10 hours of continuing medical education.

Accordingly, the Board in this matter adopts the attached Stipulation and makes the following Findings of Fact, Conclusions of Law and Order.

FINDINGS OF FACT 1. Respondent John G. Hoffmann, M.D. (DOB July 26, 1950), is licensed in the state of Wisconsin to practice medicine and surgery, having license number 26569-20, first issued on February 1, 1985, with registration current through October 31, 2017. Respondent’s most recent address on file with the Wisconsin Department of Safety and Professional Services (Department) is Post Office Box 248, Waupaca, Wisconsin 54981.

2. Respondent is a general practice physician and is not board certified.

Disciplinary History

3. The Board has previously taken the following actions in regards to Respondent’s license to practice medicine and surgery in Wisconsin:

a. On October 22, 1997, the Board suspended Respondent’s license for not less than five years, with a provision for consecutive three month stays of suspension contingent upon compliance with, among other conditions, enrollment and successful participation in a drug and alcohol treatment program, submission to drug and alcohol screens, and submission of quarterly practice and therapy reports. The order was imposed because Respondent consumed alcohol while on call and treated a patient after consuming at least four alcoholic beverages.

b. On March 3, 1998, the Board ordered the suspension be stayed for one month and that Respondent appear before the board on April 22, 1998.

c. On April 30, 1998, the Board stayed the suspension for three months.

d. On September 24, 1998, the Board extended the stay of suspension for an additional three months.

e. On December 18, 1998, the Board denied Respondent’s request for another three month stay and suspended his license for violating the terms of his limited license.

f. The Board reinstated the stay on January 20, April 1 and October 2, 1999.

g. On June 22, 2000, Respondent notified the Board of his intent to retire from the practice of medicine and his wish to surrender his registration, and the Board accepted Respondent’s surrender of his registration to practice and the right to renew it.

h. On June 8, 2004, the Board reinstated the limited license of Respondent.

i. On June 26, 2006, the Board ordered a full reinstatement of Respondent’s license.

j. On May 21, 2008, the Board ordered Respondent to undergo an assessment to evaluate his ability to practice medicine at his current practice. It was also ordered that Respondent not order, prescribe, or administer any opioid or opiate for more than 30 days in any 12 month period for any patient.

k. On November 16, 2011, the Board suspended Respondent’s license pending the outcome of a disciplinary proceeding.

l. On January 18, 2012, the Board ordered the summary suspension of the Respondent’s license and registration to be continued and stayed if Respondent did not accept any new patient and complied with terms and conditions including a professional mentor, a self-study CME program, and successfully passing the SPEX exam.

m. On October 17, 2012, the Board dismissed a pending complaint against the Respondent after he completed a neuropsychological evaluation and was found to have no cognitive deficits.

Current Case

4. On March 27, 2013, Respondent first saw Patient A for continued treatment of what was charted as “Lyme Disease – documented.” Respondent documented “chronic” Lyme disease with treatment since 2011 and abdominal candidiasis (intestinal).

5. Respondent prescribed Ceftin 500mg BID, Clindamycin 300mg BID every other day, and Diflucan 20 mg on days when not taking Clindamycin, with the plan to continue Patient A on these drugs and dosages. Respondent did not order Patient A undergo regular labs while on this medication regiment.

6. On January 6, 2014, Patient A saw another physician who became concerned with Respondent’s care and treatment of Patient A, specifically Respondent’s plan to maintain Patient A on the above-described antibiotics and antifungals, and without regular lab testing. The provider subsequently filed a complaint with the Department which initiated this matter.

7. Respondent’s treatment of Patient A’s Lyme disease fell below the minimal standard of competence by his plan to maintain Patient A on high dosages of antibiotics and antifungals, and his failure to order regular labs.

8. In resolution of this matter, Respondent consents to the entry of the following Conclusions of Law and Order.

CONCLUSIONS OF LAW 1. The Wisconsin Medical Examining Board has jurisdiction to act in this matter pursuant to Wis. Stat. § 448.02(3), and is authorized to enter into the attached Stipulation pursuant to Wis. Stat. § 227.44(5).

2. By the conduct described in the Findings of Fact, Respondent John G. Hoffman, M.D., engaged in unprofessional conduct pursuant to Wis. Admin. Code § Med 10.02(2)(h) (Nov. 2002) by any practice or conduct which tends to constitute a danger to the health, welfare, or safety of patient or public.
