Patients with chronic, severe mental illness live much shorter lives than the general population. The 25-year loss in life expectancy for people with chronic mental illness has been attributed to higher rates of cardiovascular disease driven by increased smoking, obesity, poverty, and poor nutrition.1 These individuals also face the added burden of struggling with a psychiatric condition that often interferes with their ability to make optimal preventative health decisions, including staying up to date on vaccinations.2 A recent review from Toronto, Canada, found that the influenza vaccination rates among homeless adults with mental illness—a population at high risk of respiratory illness—was only 6.7% compared with 31.1% for the general population of Ontario.3

Mental health professionals may serve as the only contacts to offer medical care to this vulnerable population, leading some psychiatric leaders to advocate that psychiatrists be considered primary care providers within accountable care organizations. Because most vaccines are easily available, mental health professionals should know about key immunizations to guide their patients accordingly.

In the United States, approximately 45,000 adults die annually from vaccine-preventable diseases, the majority from influenza.4 When combined with the most recent Adult Immunization Schedule and general recommendations adapted from the CDC,5,6 the mnemonic ARM SHOT allows for a quick assessment of risk factors to guide administration and education about most vaccinations (Table 1). ARM SHOT involves assessing the following components of an individual’s health status and living arrangements to determine one’s risk of contracting communicable diseases:

  • Age
  • Risk of exposure
  • Medical conditions (comorbidities)
  • Substance use history
  • HIV status or other immunocompromised states
  • Occupancy, or living arrangements
  • Tobacco use.

We recommend keeping a copy of the Adult Immunization Schedule (age ≥19) and/or the immunization schedule for children and adolescents (age ≤18) close for quick reference. Here, we provide a case and then explore how each component of the ARM SHOT mnemonic applies in decision-making.
