Review of Error in Diagnosis

As a retired RN/BSN of 40 years I love a good medical mystery. I thought this one was very interesting and exciting. One of my very favorite assignments in hospital care was in a neurology/neurosurgery unit for several years and I found this story fascinating in that regard as well. I will now read other books by Dr. Birken.

Too many errors in this book. Story would have been ok. First off, no neurologist from another hospital would be diagnosing a disease that was not neurological. He would not be involved in any other way once neurological diagnoses are dismissed. He would no way be on Air Firce one meeting with the president. No chief of Neurology would be diagnosing and treating a viral disease with medication. Treating a parvovirus that was not detected in testing would not happen by a neurologist. Infectious Disease would have been involved in this case. There’s absolutely NO way a chief of neurology would be performing a gynecological surgery!! Ob/gyn would be. Not neurology. It’s not the specialty he’s trained in. So unbelievable. Also so many errors, one Tess is 12 weeks when she goes into the hospital. Next she’s 28 weeks in 4 days in the hospital?? Impossible. Stating that it’s only affecting pregnant woman in their 3rd trimester then forgetting that you wrote she was 12 weeks??? Too many spelling errors also. Was there NO research, no fact finding or no editing in this book??? This was a horrible book. We are not idiots reading books!

An excellent medical thriller

Error In Diagnosis is about the national race to stop the spread of a mysterious affliction affecting only pregnant women. The book is beautifully composed with excellent characters, who have significant arcs during the book and the pacing is perfect. I can recommend this book not only to fans of medical thrillers, but fans of very complex problem solving. This is one of the best medical thrillers I've read. 5/5 stars!

night owl reader

This is one of the best medical thrillers I have ever read. The complex medical procedures were extremely well written so that an average reader would never become distracted by any misunderstanding of the situation. The author's astute character descriptions were both caustic and humorous. The thrilling ending couldn't have been more creative. The author also took time to describe the physical setting to perfection. I was so engrossed in this book that I actually felt the characters stress and exhaustion.

Fast paced informative medical thriller, for fans of "House".


A mysterious illness, GNS, is plaguing pregnant women and it is up to Dr. Jack Wyatt and Dr. Madison Shaw to negotiate the politics and egos of the hospital environment to find the underlying cause.

Very interesting and original

I enjoyed reading this story. It is a mystery of medical research and treatment of a new disease killing young pregnant women.

I spent probably the first half of the book thinking that Jack was absolutely useless - so many people raved about how great of a doctor he is and how they had to have him there, but his only answer to anything was “I don’t know”. Then, in the second half, he did EVERYTHING. and I feel like that is probably a part of being a doctor that I just never thought about. How infuriating it must be to not have the answer!

I’m hooked.

“Error in Diagnosis” is my first Birken read. I just finished it and will purchase Book 2 of the series as soon as I finish writing this review. Birken is a masterful storyteller. He weaves plausible medical scenarios, suspenseful drama, and credible characters into an intriguing saga of life and death.

dr Wyatt

This was an absolutely Great book to read. I’m sure things like this happen more often than not in the medical field. Like the Covid 19 scare. Something to think about. Glad Dr Wyatt stuck to his guns to overrule the other doctor that was not only rude but medically unethical. So glad the truth came out.

ICU RN GIVES THUMBS UP TO THIS ONE!

A Medical puzzle, hostile hospital politics, government cooperation (well, that's a new twist), and a little romance thrown in - I have no idea how it could get any better!
I found very few medical treatments or references that lightly marred the whole thing - for instance, a staff member referring to a "respirator" rather than a
ventilator, and Code Blue sequence that ended with only epinephrine given. Anyhow, I enjoyed it immensely and highly recommend it for an hour or two's reading in the evening. Trouble is, you won't want to stop until it's finished!

A great medical thriller with characters to root for. Pregnant women are coming down with an unknown disease, that is resisting all attempts at treatment. Can Madison Shaw and Jack Wyatt find out the cause and come up with a cure?

Wow!

5 stars. wow! For a first book its intense especially coming off of the civic pandemic. The book held my attention all the way to the end. I loved the characters. They were well developed and fleshed out. I'm looking forward in reading more books in this series. I give a round about review with no spoilers. Its not fair to the next reader. Each need to develop their own opinions about the book. I loved the storyline. Can't wait for another book.

Wow!

Loved reading this book. Had me worrying about patients. I can't say much more about that! Had me reading into the early morning hours, I just couldn't put it down. One of the best I've read.

Books involving the medical community have always been my weakness. Having worked with physicians/surgeons/researchers/CEOs, this book takes me back to the fascinating world of medicine. I highly recommend it.

Really Enjoyable Medical Thriller

I loved this book! The characters were really well-written, and believable. I love science, especially medicine, and Dr. Birken provided the right amount of medical information, in order to explain things necessary for the storyline, but nothing to confuse the reader. I highly recommend Error in Diagnosis by Dr. Gary Birken, and look forward to reading more of his work.

3.0/5 Not sure how this book is under the genre of "Medical Thriller" because I'm in the medical field and this was not thrilling in any way. I've read books by Gary Birken before and enjoyed them and thought this one would be perfect for a nurse like me. It was heavy on medical terms and lots of boring hospital politics. Lacked twists, turns and thrills. I won't be reading the other books in this series.

Great read

The writer keeps the reader glued to the pages, informed and entertained. This book seems to have a glaring error insofar that it doesn’t seem likely that a drug with possible severe side effects would be used nation against an unproven virus without first testing the efficacy on a few patients. In other books by this author I thought his main character was a fictional superhero. After reading Gary’s biography I’m convinced that his works may be highly auto graphical. Even with flaws I love reading his books for both information and insights into the medical/political world.

DIAGNOSIS DELIGHTFUL!

If you enjoy both science and sluething, Dr. Birkens books are a great fit. His description of the life & death drama; the commitment to discovery and both the political and personal relationship that take place in the corridors of a teaching hospital keep you so involved the reader tears through the book in one sitting. Thank goodness he is a prolific writer because his stories will turn you into a prolific reader.....I will be starting my next book now.

an unexplained disease


Jack Wyatt was called down to be a consultant at the floor of the hospital from his hospital in Ohio. There is a disease called GNS. that is affecting only certain pregnant woman. I found the story very thrilling and the characters were well written. I’d like a good medical thriller, and this certainly was it. There was danger, conspiracy, and tragedy. I recommend this book for all who like a good medical thriller.

Great Medical Thrill Ride

I couldn't put this book down, no way,
From the first page, I was hooked, hooray!
Roller-coastering, turning each page,
Until the end, my heart engaged.
I couldn't stop, I had to know,
What happened next, I couldn't go.
And when it ended, I cried with glee,
What a ride, this book and me!

Thoughts

I liked the book and will read the next in the series before deciding to continue. The plot was good, enough twists to keep me reading. There were a number (maybe too many) of characters which became confusing. Also, this needed a better proofreader as there were many errors within the story.

It's been ages since I've read a good medical thriller/mystery and Error in diagnosis was a perfect one to draw me back into this genre. The plot was very timely, the medical knowledge (the author is a physician) was extremely accurate - I checked - and the writing was impeccable. I LOVED this book and highly recommend it.

error in diagnosis

Being a retired RN, I enjoy books with a medical theme. There are places in this book I couldn’t read fast enough. I try hard to read each word but wow, had to read faster. A real,page turner. THANKFUL for the twists, turns and how the story progressed. Know exactly how Jack felt when he had those niggling feelings he missed something.
