Background: The treatment of psychiatric illnesses, prevalent in the general hospital, requires broadly trained providers with expertise at the interface of psychiatry and medicine. Since each hospital operates under different economic constraints, it is difficult to establish an appropriate ratio of such providers to patients. Objective: The authors sought to determine the current staffing patterns and ratios of Psychosomatic Medicine practitioners in general hospitals, to better align manpower with clinical service and educational requirements on consultation-liaison psychiatry services. Method: Program directors of seven academic Psychosomatic Medicine (PM) programs in the Northeast were surveyed to establish current staffing patterns and patient volumes. Survey data were reviewed and analyzed along with data from the literature and The Academy of Psychosomatic Medicine (APM) fellowship directory. Results: Staffing patterns varied widely, both in terms of the number and disciplines of staff providing care for medical and surgical inpatients. The ratio of initial consultations performed per hospital bed varied from 1.6 to 4.6. Conclusion: Although staffing patterns vary, below a minimum staffing level, there is likely to be significant human and financial cost. Efficient sizing of a PM staff must be accomplished in the context of a given institution's patient population, the experience of providers, the presence/absence and needs of trainees, and the financial constraints of the department and institution. National survey data are needed to provide benchmarks for both academic and non-academic PM services.
