Jan Mozny

Introduction

Dr Jan Mozny is a former locum consultant medical oncologist at University Hospitals of Derby and Burton NHS Foundation Trust who has been struck off the medical register after a tribunal found him to be “a danger to the public.” Mozny was first suspended in April 2023 for failing six patients in March 2020 — prescribing chemotherapy with no supporting correspondence, prescribing the wrong course of treatment for another patient, and seeing a third without completing paperwork or passing on their CT scan results. Rather than resolving the case, the suspension began a three-year cycle: nine months of suspension, then nine more, then a further year, each imposed because Mozny showed no evidence of insight, remediation, or updated skills, until the Medical Practitioners Tribunal Service ruled in October 2026 that erasure was the only outcome left.

Background Information

Mozny qualified in 1976 at Charles University in Prague, giving him nearly half a century in medicine by the time of his erasure. He was working as a locum consultant specialising in medical oncology for University Hospitals of Derby and Burton when the failures occurred in March 2020 — at the height of the pandemic’s first wave, when oncology services were under exceptional strain. Oncology is among the least forgiving specialisms for error: the drugs are cytotoxic, the treatment windows narrow, and the patients already seriously ill. The tribunal found his failures affected six patients in a single month: one received chemotherapy with no correspondence to support the decision, another received the wrong course of treatment, and a third was seen but no paperwork was done and they were not given their CT scan results. A regulator’s assessment that a doctor so experienced poses a danger to the public is what makes the case notable; the GMC’s case was not about a single lapse but about what happened across the four years after the first suspension.

The Controversy or Incident That Led to Their Cancellation

Struck off by the medical tribunal. After three consecutive suspensions for failures in cancer care in March 2020, the MPTS ruled that Mozny’s continuing lack of insight made erasure “the necessary and proportionate outcome.”

The original misconduct, found in April 2023, concerned six patients in March 2020. For it, Mozny was given the first of a series of suspensions — nine months — with the expectation, standard in such cases, that he would use the time to reflect, remediate, and demonstrate he could safely return. That did not happen. He was suspended for a second nine months, and then for a further year, each extension imposed because, as the final hearing was told, there had been “no progress made in relation to remediation, insight, remorse, regret or any evidence that Dr Mozny had endeavoured to keep his knowledge and skills up to date.” The panel added that he had failed to “engage meaningfully with either the recommendations of the previous tribunals or more generally with his regulator the GMC.”

Mozny did, at one point, signal acceptance of the end: in a letter he said he intended to voluntarily erase his name from the General Medical Council’s register, adding he had no intention of working in medicine again either in the UK or abroad. But the tribunal did not treat the letter as resolution. At the hearing in October 2026 it ruled that erasure from the register was the “necessary and proportionate outcome” to protect the public, uphold professional standards, and maintain confidence in medicine — converting what he had offered to do voluntarily into a formal striking-off that closes the file with a public finding that he was a danger to the public.

Public Reaction and Consequences

The BBC’s report of the case, published on October 27, 2026 under the headline “‘Dangerous’ Derby doctor struck off after failing to quit,” framed the outcome plainly: a doctor found dangerous could no longer practise. The case is a study in the regulator’s escalation ladder — suspension is meant to be a supervised opportunity to remediate, and Mozny consumed three consecutive suspensions without producing the insight any of them required. The tribunal’s final decision documented that failure in the regulator’s own language, and the erasure means the six-patient failure in March 2020 now ends not with a return to practice but with a permanent bar and a published finding that his continued presence on the register would undermine confidence in the profession.

Current Status

Mozny has been erased from the medical register by the Medical Practitioners Tribunal Service’s October 2026 ruling. He is in his late seventies or older — he qualified in 1976 — and has stated in a letter that he has no intention of practising medicine again in the UK or abroad. The erasure converts that stated intention into a formal bar: he cannot reapply, and the finding that he was a “danger to the public” stands in the published record. No appeal was reported in the coverage of the hearing.

Impact on Their Career/Life

Mozny’s case closes a medical career that spanned from 1976 in Prague to an NHS oncology consultancy in Derby, ended not by a single catastrophic error but by a pattern of failure and a four-year refusal to engage with the process meant to fix it. The tribunal’s account — six patients failed in one month, three suspensions consumed without insight, a letter promising voluntary erasure that the tribunal declined to accept as the final word — documents both the clinical failures and the regulatory ones. For the patients whose chemotherapy decisions lacked correspondence, whose treatment course was wrong, and whose CT scan results never reached them, the erasure provides no remedy, but it does provide the system’s answer: the doctor found responsible cannot practise again.
