Hospitalists are typically employed in a variety of public and private hospital settings on a contractual or salaried basis. Traditionally, career medical officers or hospitalists are employed as permanent full-time or part-time staff, but more commonly in recent times, due to a significant workforce of clinicians been in-flux with their specialty training and insufficient staffing of middle-grade clinicians at hospitals, there has been an increase supply and demand for hospitalists on a "locum tenens" or casual basis. Dependent on their place of employment and duties, the responsibilities and remuneration of non-specialist hospitalists are usually comparable to somewhere between registrars and consultants. Despite the common trend for clinicians to specialise nowadays, non-specialist hospitalist clinicians have an important role in fulfilling shortages in the medical workforce, especially when specialist (or registrar) coverage and accessibility is unavailable, where there is an area-of-need, and after-hours or on-site medical care is required. These clinicians and employed across Australia in a variety of clinical environments which include Medical & Surgical Wards, Mental Health Units, Intensive Care Units and Emergency Departments. Nonetheless, these clinicians work closely and continually consult with the relevant attending specialists on-call; that is, final responsibility and care for the patient ultimately still rests with the attending specialist.
