Medical psychiatry: The skill of integrating medical and psychiatric care

Medicine is our calling

Many of these illnesses, even when identified, require expert psychiatric management of psychiatric symptoms. This should not be surprising to psychiatrists or other clinicians. No one expects a cardiologist to beg off the care of a patient with heart failure caused by alcohol abuse or a virus rather than vascular heart disease, and psychiatrists likewise need to manage psychosis due to steroid use or N-methyl-d-aspartate receptor antibodies as well as other causes. Pursuing this understanding is important from another perspective. As we consider other potential mechanisms for onset of psychiatric illness (eg, inflammation), our understanding of the mechanisms associated with general medical conditions may provide unexpected insight into the etiology of psychiatric illnesses where no general medical cause has been found. No other physician specialists are as attuned to the nuances of psychiatric illnesses, their typical and atypical presentations as psychiatrists. It is incumbent on us to pursue the medical differential of patients when we think it is needed, even if other physicians disagree.

Medical psychiatry has a broader and more inclusive perspective than what we generally mean by “biological psychiatry,” if by the latter, we mean a focus on the neurobiology and psychopharmacology of “primary” psychiatric conditions that are not secondary to other medical or neurologic disorders. As important and fundamental as deep understanding of neurobiology, genetics, and psychopharmacology are, medical psychiatry embeds our work more broadly in all of human biology and requires the full breadth of our medical training.

At a time when political battles over prescriptive privileges by non-medically trained mental health clinicians engage legislatures and professional organizations, medical psychiatry is a powerful reminder that prescribing or not prescribing medications is the final step in, what should be, an extensive, clinical evaluation including a thorough medical work up and consideration of the medical–psychiatric interactions and the differential diagnosis of these illnesses. It is, after all, what physicians do and is essential to our calling as psychiatric physicians. If psychiatrists are not at home in medicine, as Tom Hackett reminded us in 1977¹—at a time when psychiatry had temporarily eliminated the requirement for medical internships—then, indeed, psychiatry would be “homeless.”
