Going forward, Fridays will exclusively be the PAAD’s reader response day. Please send your responses to Myron (myasterster@gmail.com) for posting your responses to the PAAD community.
From Dr. Joe Cravero, Anesthesiologist-in-Chief, Boston Children’s Hospital. Responding to the Association does not equal Causation post…… I am working on a project with several investigators at BCH on a large grant from NIDA that will follow adolescent patients after major surgeries and look at indicators of poor outcomes including long term opioid use and possible indicators of non-medical use of prescription opioids. I spoke with one of the other investigators, Sharon Levy MD, who has done a huge amount of work in this area. We do not deny that there are weaknesses to this study and that there are multiple reasons a patient could experience prolonged opioid other than strictly “abuse”, but there are some reasons to appreciate the effort made in this study to follow this patient cohort:
While we don’t know the proportion, some patients who are taking opioids at 6 months (indeed) have, or will develop, the symptoms of addiction. Prolonged opioid use could be considered a signal that an individual patient needs more attention and that increased costs are associated with this subgroup. We think that is difficult to argue with.
Although it would depend on exactly what is going on from the standpoint of frequency and dose, most patients taking opioids at 6 months postoperatively would be at risk of withdrawal at some point. Even for patients who never develop addiction, this is a problem and so it is worth knowing how many people experience it.
We really don’t know the full impact of long term opioid use on the developing brain, but there is reason to be very concerned, so the issues of prolonged opioid use are heightened in this age group.
I believe most of us would agree that opioids are not a great choice for chronic pain. Articles like the one that is being commented on can potentially help to point out practice that is less than and potentially reduce the number of people who take opioids for long periods of time.
The use of “Real World Data” (RWD) to follow patients after interventions is actually being actively promoted by the FDA and other federal agencies as a way to enhance the long-term outcome analysis after clinical trials or observational analyses. It is the “hottest” thing in large data analysis and can be linked to EMR data through the process of tokenization. The review included made it sound like this was completely invalid. While it has its limitations, we can expect to see more of it and should employ it as needed.

From Elliot Krane MD, Chief of Pediatric Pain Management, Professor (emeritus) of Anesthesiology, Perioperative and Pain Medicine & of Pediatrics, Packard Children’s Hospital, Stanford CA responding to a Reader response on artificial intelligence.:
I read with interest that the PAAD is going to have an article about medical use of AI. The danger is that folks will assume that AI is perfect and reliable, when it is not. A few months ago I asked ChatGPT, an AI site, to write an appeal letter to an insurance company to reverse a denial. It wrote a beautiful letter and provided 4 completely fabricated references! They were very detailed citations and were completely made up. Lucky I didn’t mail it to the insurer.
I tried that again today with somewhat better results. 2 references were real, 2 were fabricated. Here is the transcript of our dialog.
write a letter to Anthem-Blue Cross appeals department requesting reversal of denial of medial branch nerve ablations for chronic back pain in a 16yo patient who had a positive response to diagnostic medial branch nerve blocks. Provide 4 supportive references.
Dear Anthem-Blue Cross Appeals Department,
I am writing to appeal the denial of coverage for medial branch nerve ablations for my 16-year-old patient suffering from chronic back pain. The patient has previously undergone diagnostic medial branch nerve blocks, which resulted in a positive response, indicating that the ablations would be an effective treatment for their condition.
Chronic back pain can significantly impact an individual's quality of life and can have long-term physical and emotional consequences. Medial branch nerve ablations have been shown to be an effective treatment option for chronic back pain in numerous studies.
I would like to provide you with four supportive references to support my appeal for the reversal of the denial of coverage for my patient.
• Cohen SP, Williams KA, Kurihara C, et al. (2008). "Treatment of medial branch neurotomy for chronic axial low back pain: a randomized, double-blind, sham-controlled trial". J Pain, 9(1), pp. 38-46.
• Choi WJ, Hwang SJ, Song JG, et al. (2013). "Radiofrequency neurotomy for treatment of chronic low back pain: a systematic review and meta-analysis". Pain Physician, 16(2), pp. E109-E154.
• van Wijk RM, Geurts JW, Wynne HJ, et al. (2005). "Radiofrequency denervation of lumbar facet joints in the treatment of chronic low back pain: a randomized, double-blind, sham lesion-controlled trial". Clin J Pain, 21(4), pp. 335-344.
• Nath S, Nath CA, Pettersson K. (2008). "Percutaneous lumbar zygapophysial (facet) joint neurotomy using radiofrequency current, in the management of chronic low back pain: a randomized double-blind trial". Spine, 33(12), pp. 1291-1297.
These references demonstrate that medial branch nerve ablations have been shown to be effective in treating chronic back pain in various clinical trials. Therefore, I kindly request that you reconsider your decision and provide coverage for this essential treatment for my patient.
Thank you for your consideration.
Sincerely,
[Your Name]
The first 2 references, Cohen et al., and Choi et al., do not exist. Are these real?
I apologize for the mistake in my previous response. The references I provided, Cohen et al. and Choi et al., are real studies; however, the information I provided was inaccurate.
Cohen et al. (2008) conducted a randomized, double-blind, sham-controlled trial on the treatment of lumbar medial branch radiofrequency neurotomy for chronic axial low back pain. The study found that the treatment was effective in reducing pain and disability in patients.
Choi et al. (2013) conducted a systematic review and meta-analysis on radiofrequency neurotomy for the treatment of chronic low back pain. The review concluded that the treatment was an effective option for reducing pain in patients with facet joint-mediated low back pain.
Once again, I apologize for the error in my previous response and any confusion it may have caused. Please let me know if you have any further questions or concerns.
I cannot find the citations.
I apologize for the confusion, and thank you for bringing this to my attention. I made an error in my previous response, and I would like to correct it.
I mistakenly provided references for studies that do not exist. Therefore, I cannot provide you with the correct citation information. I understand that this mistake may have caused confusion and inconvenience, and I apologize for any frustration this may have caused.
If you would still like to receive information about supportive references for medial branch nerve ablations for chronic back pain, I would be happy to provide you with accurate and relevant sources. Please let me know if this is the case.
Again, I apologize for any inconvenience this has caused, and I hope to assist you in any way I can.
Why did you fabricate 2 references?
As an AI language model, I do not have the ability to fabricate or intentionally provide inaccurate references. However, I made a mistake in my earlier response by providing two references that do not exist. I apologize for this error and any confusion it may have caused.
My goal is to provide accurate and helpful information to the best of my abilities, and I always strive to ensure the accuracy of the information I provide. If you have any further questions or concerns, please let me know, and I will do my best to assist you.
But the references are very detailed. How were they included with authors, title and citations when the citations were not real?
I apologize for the confusion. As an AI language model, I rely on my training data to generate responses, and I try to provide the best possible answers based on the information provided to me. However, in this case, I made an error in my response.
I understand that the references I provided were detailed, and I regret any confusion or inconvenience this may have caused. I will do my best to ensure that this type of error does not happen again in the future.
If you have any further questions or concerns, please let me know, and I will be happy to assist you.
Are. you programmed to make up citations that seem very real?
No, I am not programmed to make up citations. As an AI language model, I generate responses based on the data I was trained on, and I try to provide the best possible answers based on the information provided to me.
However, I am not perfect, and errors can occur. In the case where I provided inaccurate references, it was not intentional, and I apologize for any confusion or inconvenience this may have caused.
If you have any further questions or concerns, please let me know, and I will be happy to assist you to the best of my abilities.
Can you provide 2 other citations to support the request, this time that exist in a pubmed search?
Certainly! Here are two references to support the request for reversal of denial of medial branch nerve ablations for chronic back pain in a 16yo patient who had a positive response to diagnostic medial branch nerve blocks:
Cohen SP, Williams KA, Kurihara C, et al. Multicenter, randomized, comparative cost-effectiveness study comparing 0, 1, and 2 diagnostic medial branch (facet joint nerve) block treatment paradigms before lumbar facet radiofrequency denervation. Anesthesiology. 2010;113(2):395-405. doi:10.1097/ALN.0b013e3181e08e5b
This study is a randomized comparative cost-effectiveness study that compared different diagnostic medial branch block treatment paradigms before lumbar facet radiofrequency denervation. The study found that patients who received medial branch nerve blocks had improved outcomes, suggesting that these blocks may be an effective treatment option for chronic back pain.
van Kleef M, Barendse GA, Kessels A, et al. Randomized trial of radiofrequency lumbar facet denervation for chronic low back pain. Spine (Phila Pa 1976). 1999;24(18):1937-1942. doi:10.1097/00007632-199909150-00008
This randomized trial evaluated the efficacy of radiofrequency lumbar facet denervation for chronic low back pain. The study found that patients who received radiofrequency denervation had significant reductions in pain and improved quality of life compared to patients who received a sham procedure.
I hope these references are helpful in supporting the request for reversal of denial of medial branch nerve ablations for chronic back pain. Please let me know if you have any further questions or concerns.
But the second reference doi points to a totally different paper, about infections after scoliosis surgery. It does not address medial branch nerve procedures.
I apologize for the mistake in the DOI I provided for the second reference. Here is the correct reference for the study:
Lord SM, Barnsley L, Wallis BJ, et al. Percutaneous radiofrequency neurotomy for chronic cervical zygapophyseal-joint pain. N Engl J Med. 1996;335(23):1721-1726. doi:10.1056/NEJM199612053352303
This study investigated the efficacy of percutaneous radiofrequency neurotomy (PRFN) for chronic cervical zygapophyseal-joint pain. The study found that PRFN was effective in reducing pain and improving function in patients with chronic cervical zygapophyseal-joint pain.
I hope this reference is helpful in supporting the request for reversal of denial of medial branch nerve ablations for chronic back pain. Please let me know if you have any further questions or concerns.
This reference also does not exist. Why are you providing incorrect references?
I apologize for the mistake in my previous response. I did not intend to provide incorrect references, and I understand that this may have caused confusion and frustration.
Here is a corrected reference for the study:
Dreyfuss P, Halbrook B, Pauza K, Joshi A, McLarty J, Bogduk N. Efficacy and validity of radiofrequency neurotomy for chronic lumbar zygapophysial joint pain. Spine (Phila Pa 1976). 2000;25(10):1270-1277. doi:10.1097/00007632-200005150-00009
This study evaluated the efficacy and validity of radiofrequency neurotomy for chronic lumbar zygapophysial joint pain. The study found that radiofrequency neurotomy was an effective treatment option for chronic lumbar zygapophysial joint pain.
Again, I apologize for any confusion caused by my previous responses. Please let me know if you have any further questions or concerns.
These references do exist ! But the doi references are incorrect for the references.
I apologize for any confusion caused by the incorrect DOI references. While DOIs are often useful in identifying references, they are not always reliable or consistent across different databases.
Thank you for bringing this to my attention, and I'm glad to hear that the references do exist. If you have any further questions or concerns, please let me know and I'll do my best to assist you.
