Peter C Gøtzsche and Anders Sørensen are from the Institute of Scientific Freedom, which, according to their website, works to preserve honesty and integrity in science and to help develop a better healthcare where more people will benefit; fewer will be harmed; and more will live longer in good health (1). The vision is very noble and shows that they value the interests of patients. Their other associated website has blog posts which argue against overdiagnosis of psychiatric disorders and over prescription of drugs (2). However their current study goes beyond reasonable critique as evidenced in their methodology and interpretation of results (3).
In their study, Peter C Gøtzsche and Anders Sørensen studied the records for 30 consecutive patients who appealed decisions about antipsychotic medications to the Psychiatric Appeals Board in Denmark. They do not explain why these 30 were selected and do not report how many such appeals are filed. In fact there were only 1488 complaints received by the psychiatric patients’ complaints board in nearly a decade from January 1, 2010 to September 18, 2020 (4). It would be important to see these numbers in the light of total number of patients with mental illness who accessed care in Demark in the same time frame. It is necessary to see the extent of the problem that the authors allege is rampant and global. In the introductory section they assert that benefits from antipsychotics are uncertain by citing three books from “antipsychiatry” literature and one paper which looked at data from new drug trials (5)! They not only think that doctors are abusing power but they allege that they are hand in glove with their oversight body. Do they forget that it is the same body which gave them access to data for the current study? The content of the material which they studied was written down by the doctors whom the authors are trying to discredit. If the doctors were trying to play foul would they document the information which would incriminate them? This is not the only blind spot the authors have.
The authors describe instances of patients having adverse drug reactions which were recorded by the psychiatrists, who decided to continue with those drugs for reasons which were considered acceptable by the regulatory authority. Even in an audit, specialists in the field review the files and ask the treating doctors for explanations; but here the authors ─ who are not trained as psychiatrists─ have passed judgement on the clinical decisions of psychiatrists. In fact, psychiatrists are trained to assess the potential risks and benefits of their interventions and non- intervention like any other health professional
The authors also recommend benzodiazepines and psychotherapy as options to be considered. They fail to note that even these interventions can be harmful. Even meta-analyses on the efficacy of psychotherapies suggest that up to half of the patients do not show significant change, and in about 5–20% of patients, adverse events could be expected (6); and that guidelines emphasise that benzodiazepines are not the first choice of treatment (7).
They also question the diagnosis of delusions by competent personnel who have examined the patients, when they themselves have not examined the patients. Is this not as unethical as diagnosing without examination? Psychiatrists are trained in mental status examination, as physicians are trained in physical examination and they diagnose delusions in a reasonably objective manner.
Most importantly, the authors turn a blind eye to the realities of mental illness. There is loss of insight in psychosis (8). Patients who have the condition do not believe that they have any problem. They suffer a lot because of their beliefs and can pose a threat to themselves and others. They are not to be punished for their behaviours but should be provided care. For example, the person described by the authors, who threatened to kill people, should not be tried in a court for his threats, but should be given treatment so that he could regain a sense of reality and control. Ignoring common knowledge about severe mental illness, the authors seem to take the content of the speech of the patients as “truth”. This is as wrong as dismissing everything that a patient says as false.
The authors also seem to be unaware of the timeline of illness evolution and time lag in treatment response. When treatment starts early in the course of illness, there is a possibility of worsening of the symptoms after the start of treatment. This is not the effect of the medication but occurs despite the medication being given due to the evolving illness and the time lag before responding to the medication (9, 10).
The authors claim that there is no scientific basis for the use of antipsychotics. They cite some recognised methodological challenges in studies in psychiatry. However, they also try to conflate the issue by bringing up placebo controlled studies. It is important for us to know that doing placebo controlled studies in serious mental illness is not easy. In 2006, the Indian Journal of Medical Ethics published a discussion on a controversy arising from a placebo controlled study in India (11). The questions raised were addressed by the principal investigator (12). In that study, at the end point the proportion of patients whose severity of illness (CGI scale) was rated as “not ill,” “mild,” or “very mild” in the placebo arm, increased from 1% at baseline to 37%. This does make a case for the presence of placebo response. However, in the drug arm the increase was from 0 per cent to 72 per cent, clearly showing much greater effect due to treatment with the drug (13). Scientists recognise that the adverse effects of drugs can affect blinding and that improvement can be because of the natural course of illness. However, the overwhelming evidence is in favour of antipsychotics.
It is considered unethical to include patients with severe illness like severe depression in placebo controlled trials, and therefore participants in clinical trials are those with illness of mild to moderate severity. The placebo response in these patients is likely to be greater than in those with severe illness. This leads to underestimation of efficacy in the literature. However, clinicians treating patients with severe depression witness the efficacy of antidepressant drugs.
I am an able bodied middle aged male with old parents, a middle aged wife, a sister and two young children. In the event of severe mental illness, I am capable of causing immense damage to them if my behaviour is not controlled with appropriate treatment. I hope, in such a situation, my friends and extended family would move me to a psychiatric facility. The doctors might have to coerce me to be admitted and take medication. I am likely to oppose this vehemently and might even complain to the mental health tribunal. I only hope they would recognise that what I am doing is because of my illness and would give me an opportunity to get better with appropriate treatments. I do not mind if I am coerced, as I hope to recover and regain my capacity to live a fulfilling life. Studies done in India on the perspectives of remitted psychiatric patients and caregivers about the use of physical restraints showed a widespread acceptance of restraints over seclusion; and of involuntary treatment with the consent of a family member and in the presence of the family member near the patient during the intervention (14, 15). If someone took the authors seriously and abandoned the provision of care for psychiatric patients under special circumstances, it would be a travesty of justice even though it is shrouded in terms from ethics and human rights. In India, The Mental Healthcare Act, 2017, protects the rights of persons with mental illness to receive care and respect of choice by taking a nuanced approach on capacity to take treatment decisions through informed consent, advance directives, nominated representatives and mental health review boards.(16)
Peter C Gøtzsche has long held beliefs against psychiatry especially regarding the validity of psychiatric diagnosis and the efficacy of psychiatric treatments. He has authored books on these issues. His two books have the term “deadly” referring to medicines (17) and “psychiatry”(18) in their titles He is likely to have an academic bias being invested in these beliefs, academic bias being the bias or perceived bias of any scholar allowing their belief to shape their research and the scientific community. In a recent editorial, Arne May captures it well saying “The worst enemy of science is personal belief” (19).
The authors have been extreme in their use of language throughout the article. Their negative attitude towards psychiatry as a discipline and psychiatrists as professionals is palpable. The content that they present from the perspective of patients is likely to be accurate. However, the sweeping generalisations, unfair criticism, condescending judgementality and baseless recommendations are more indicative of their bias than based on their data. It is clear that they want to advocate for patients. Their critique of overdiagnosis may have value. Issues of mental health like diagnosis, insight, judgement, capacity, risk assessment and treatment are complex. These need nuanced discussion not simple slogans from either social constructionists or biological reductionists. The authors should continue to do advocacy for psychiatric patients by being with them and learning from them in psychiatric hospitals, nursing homes, outpatient departments, day care facilities and community not from ivory towers of advocacy and academic institutes. In doing so they may gain a different perspective about the challenges faced by mental health professionals and thereby bring nuance into their argument.
