Despite the vast research conducted to better understand biological mechanisms underlying psychosis, people with psychotic disorders continue to suffer.

Schizophrenia is associated with substantial economic costs. According to the most recently published estimates, the total cost associated with schizophrenia in the US in 2013 was $155.7 billion.1 While this number is staggering in itself, even more striking is that the indirect costs such as those related to lost productivity, unemployment, premature mortality, and caregiving made up 75% ($117.3 billion) of this burden, dramatically overshadowing the direct costs of inpatient hospital stays, emergency room visits, outpatient visits, and prescription medications.1 These statistics speak to the enormity of the toll that schizophrenia and related psychotic disorders have on the whole spectrum of patients’ lives. Psychiatry, not unlike other areas of medicine, tends to take a reactive approach to treatment. Especially in the US, health insurance does not pay for treatment unless a condition is sufficiently severe or disabling, and we typically wait for a serious problem to arise before we take action. By the same token, psychiatric clinicians tend to focus somewhat narrowly on stabilization.
We may think our jobs are done once a distressing symptom, behavior, or other crisis has been sufficiently reduced or stabilized. However, the disproportionately high burden of schizophrenia’s indirect costs suggests that our reactive approach is not working so well for our patients. These data serve as a call to action for psychiatry to shift from the traditionally reactive to a more proactive approach to patient care—one that does more to meet patients where they are. In the US, the biomedical framework has dominated how we view schizophrenia. In 2019, the National Institutes of Health spent $263 billion on schizophrenia research,2 with funding awarded primarily to studies investigating genetic, molecular, or circuit related mechanisms underlying the illness. Although such research is important for identifying new and better treatment targets, uncovering biomedical insights alone is insufficient to help our patients. Despite the vast research conducted in the past several decades to better understand biological mechanisms underlying psychosis, people with psychotic disorders continue to suffer, and so much about schizophrenia remains unknown.
Critically, we do not have a clear understanding of what causes schizophrenia or even what constitutes the main gestalt of the illness. Rather, we often resort to describing the illness in roundabout ways, such as by listing its assorted symptoms. How many scientific articles and book chapters on schizophrenia start with a sentence describing schizophrenia as a “devastating illness characterized by hallucinations, delusions, disorganized thinking, and bizarre behavior”? Sentences like these mirror the way schizophrenia is conceptualized in the DSM, but they do not provide a clear sense of what causes these myriad symptoms or how the symptoms relate to one another. Importantly, as anyone who has worked with patients knows, people are much more than a collection of their symptoms. Symptom remission is the primary outcome measure used in many clinical trials. Likewise, clinicians are trained to think operationally about what symptoms or behaviors they seek to target with a particular intervention—whether it is a specific medication, dose change, or hospitalization. However, the disproportionate impact of schizophrenia on indirect costs highlights the urgent need for psychiatry to go beyond the relatively narrow scope of symptom remission to focus more attention and effort on improving functional recovery and quality of life.
How can we accomplish this? The challenge is that there is no single algorithm for achieving this goal. Heterogeneity is inherent among people with psychotic disorders, and one size does not—and will not—fit all. We can, however, leverage one guiding principle—the importance of meeting people where they are. The 4 articles in this Special Report provide valuable perspectives on some of the ways we can meet people where they are.
In his article on stage-specific treatment of psychotic disorders, Patrick D. McGorry, MD, PhD, highlights the differing needs of individuals across the various stages of illness. The philosophy is akin to treating patients with cancer; these patients are not uniformly treated with chemotherapy but rather are prescribed individually tailored treatment based on the specific stage of illness. In psychiatry, we need to consider psychotic disorders not as a single monolithic disorder, but rather a disorder that unfolds in stages. As such, we need to focus our efforts on preventing or delaying progression to subsequent stages, from which recovery may be more challenging. This stage-specific framework for understanding and treating psychotic disorders incorporates important public health principles, including aims for primary and secondary prevention.
In the article on prescribing hope for recovery by Patricia E. Deegan, PhD, we hear the voice of someone who is not only an academic expert and pioneer in the topic of recovery, but also someone with lived experience. Dr Deegan is uniquely positioned to help clinicians understand how to effectively engage and empower individuals with psychosis to find hope and meaning by incorporating goals and preferences that matter to them. Everyone has dreams, hopes, values, preferences, and interests. Dr Deegan reminds us that symptom reduction might be helpful, but only in the service of personally meaningful goals.
The article on phenomenology and disordered selfhood by Josef Parnas, MD, and Maja Zandersen, MSc, PhD, highlights the importance of going beyond symptom checklists to understand the subjective experience of individuals with schizophrenia. They remind us that we must listen to what our patients tell us to appreciate the phenomenological essence and experience of schizophrenia spectrum disorders. This kind of careful listening and exploration, which involves joint collaboration as well as putting oneself in the mindset of the patient, can lead not only to improved understanding and prediction of schizophrenia, but may also be therapeutic in itself.
Last but not least, Antonio Waldo Zuardi MD, PhD, and José Alexandre Crippa, MD, inform us about the therapeutic potential of cannabidiol in individuals with psychotic disorders. Many patients look to and experiment with complementary and alternative products, whether for recreational use or perceived health benefits. Given the abundant evidence of the detrimental effects of cannabis on psychosis and psychosis risk, clinicians may be wary of any ingredients in cannabis. The authors differentiate the potentially anxiolytic and antipsychotic effects of cannabidiol from the psychotomimetic effects of THC. While cannabidiol is not approved for clinical use, Dr Zuardi and Dr Crippa summarize the research, which may be controversial and confusing for clinicians.
I am thrilled that the knowledge and perspectives of these experts could be brought together for clinicians. The hope is that the insights and recommendations in this Special Report can help psychiatry to go beyond what the biomedical model has traditionally prescribed for schizophrenia and proactively meet people where they are. We cannot afford not to, as underscored by $155.7 billion in economic costs associated with schizophrenia. Above all, meeting people where they are is a matter of public health—the health and quality of people’s lives depend on it.
