Pressure ulcers are wounds that develop due to reduced blood flow, typically in patients who lie in the same position for long periods. Elderly and critically ill patients are at particular risk. A study based on 2006-2007 Medicare data found that patients with pressure ulcers are more likely to die in-hospital (odds ratio 2.81); have more than double the average length of stay; and are more likely to be readmitted within 30 days of discharge (odds ratio 1.33).

Asthma and chronic obstructive pulmonary disease (COPD) are two of the most common lung disorders in the United States. Differential diagnosis can be a challenge. According to the American Academy of Family Physicians guidelines on distinguishing asthma from COPD, asthma generally has earlier onset, more variable symptoms, and normal chest X-ray. Many options for diagnosis and treatment are available, including recently developed digital health tools.

Fluid overload is a common complication in severely ill patients. In a 2015 retrospective study of 63,000 patients, fluid imbalance increased average length of stay from 8 to 11.5 days. This included increasing average ICU length of stay from 3.6 to 6.2 days.

Heart failure can be classified by ejection fraction. In heart failure with reduced ejection fraction (HFrEF, aka LVEF), the left ventricle pumps out an unusually low fraction of the blood that enters it. HFrEF has been a focus of research efforts, because most studies find it is associated with higher mortality than heart failure with preserved ejection fraction (HFpEF).

Osteoporosis is a major cause of fractures in American women. A study in the March 2018 volume of Osteoporosis International found that hip fracture rates have plateaued at an unexpectedly high level from 2013-2015, leading to an excess of 11,000 hip fractures over projections based on continuing decline.

Iron deficiency anemia (IDA) is a condition in which the body has too little iron to properly supply red blood cells, leading to fatigue and weakness. According to the Merck Manual, blood loss is the most common cause of IDA. About 70% of the body's iron is already in red blood cells, rather than stored in reserve, so patients may require iron supplementation after major blood loss.
