Hammond was one of those who broke the story about the
Bristol heart scandal in 1992 and was later called to give evidence at the subsequent enquiry. In 2009, Hammond broke allegations about
pathology misdiagnosis in Bristol, the subject of an independent inquiry chaired by Jane Mishcon. He also campaigned for an inquiry into the sacking of
Cornwall Council chief executive John Watkinson. His
Private Eye columns are available on his website. In July 2011, Hammond co-authored a
Private Eye special investigation with Andrew Bousfield called
Shoot the Messenger, exposing the shocking treatment of NHS
whistleblowers and how large sums of public money are used to silence them and cover up their concerns. It triggered an
early day motion in Parliament by
Peter Bottomley, MP. Hammond and Bousfield also launched a website dedicated to NHS staff, patients and relatives who have highlighted concerns about safety in the NHS. They were involved in referring
Barbara Hakin to the
General Medical Council. Hammond co-authored ''Trust Me, I'm a Doctor
(Metro Books) with Michael Mosley, the executive producer of the BBC2 series of the same name. There are two editions (1999 and 2002), both out of print. Hammond is the sole author of Medicine Balls – Consultations with the World's Greatest TV Doctor
(2007, 2008) and Trust Me, I'm (Still) a Doctor
(2008, 2009) and Sex, Sleep or Scrabble? - Seriously Funny Answers to Life's Quirkiest Questions
(2009, 2010) and What Doctors Really Think...16 Years of Wit, Wisdom, and Lies
(2014). His most recent book is Staying Alive: How to Get the Best From the NHS'' With
David Spicer, Hammond wrote a four-part
BBC Radio 4 satire called
Polyoaks, about GPs struggling with the then-government's NHS reforms. First broadcast in June 2011, it starred
Nigel Planer,
Tony Gardner,
Celia Imrie,
David Westhead,
Carla Mendonça,
David Holt,
Phil Cornwell and
Kate O'Sullivan, with a second series of four transmitted in 2012. Spicer and Hammond's third series of four episodes of
Polyoaks ran on
BBC Radio 4 from 6 June 2014. The fourth series, consisting of six episodes, was broadcast in 2016. A fifth series was commissioned for broadcast in 2017. In 1999, he was reported to the
General Medical Council by
William Hague's press secretary over an article he wrote about Hague's slow recovery from a cold. He writes for the
Mendip Times, celebrating life on the
Mendips and in surrounding areas. In 2021, he published ''Dr Hammond's Covid Casebook
, a collection of 30 of his fortnightly columns in Private Eye'' which formed a detailed analysis of the management of the
COVID-19 pandemic in England. ==Politics==
