Predicting Older Adults’ Risk of Developing Pneumonia

In a study published in July 2016 in the Journal of American Geriatrics Society, researchers developed a “prediction score” to help healthcare professionals determine which older adults might be most at risk for developing pneumonia.

A release from the society notes that pneumonia is a leading cause of sickness and death among older adults. About 40 percent of older adults with pneumonia are hospitalized and face high rates of complications and death. Risk factors for pneumonia include increasing age, chronic lung disease, smoking, being underweight, and having difficulty functioning.

To determine their prediction score, researchers studied older adults enrolled in the Adult Changes in Thought (ACT) study. The study’s participants included 3,392 older adults living in the Seattle area. They were 65-years-old or older, dementia-free, and did not have any cognitive (thinking) problems.

During the study, 642 participants were diagnosed with pneumonia; 574 died. The researchers determined that the seven factors critical to a pneumonia prediction score included:

  • Age
  • Sex
  • Chronic obstructive pulmonary disease (or COPD, a group of lung diseases that block airflow and make it difficult to breathe)
  • Congestive heart failure
  • Body mass index (being underweight or overweight)
  • Prescriptions for inhaled or oral corticosteroids (a class of steroid hormones used to treat a variety of conditions including some skin diseases, certain allergic reactions, asthma, and joint pain or inflammation, among other health concerns)

Doctors could potentially use the pneumonia prediction score to encourage older adults to get the pneumococcal vaccine that protects against pneumonia, as well as to counsel at-risk individuals about positive behavioral changes such as quitting smoking, said the researchers.


About the Health in Aging Foundation

This research summary was developed as a public education tool by the Health in Aging Foundation. The Foundation is a national non-profit established in 1999 by the American Geriatrics Society to bring the knowledge and expertise of geriatrics healthcare professionals to the public. We are committed to ensuring that people are empowered to advocate for high-quality care by providing them with trustworthy information and reliable resources. Last year, we reached nearly 1 million people with our resources through We also help nurture current and future geriatrics leaders by supporting opportunities to attend educational events and increase exposure to principles of excellence on caring for older adults.
