The principal diagnoses for hospitalizations generally varied by age, although some conditions were frequent among all ages.
Infants, children and young adults:
- Pregnancy, childbirth, and liveborn infants:
- In 2008, most discharges for children under one year old (89 percent) were for liveborn infants, which increased 12 percent between 1997 and 2008.
- Among 18-44 year olds, previous C-sections increased 96 percent between 1997 and 2008, while normal pregnancy and/or delivery fell 48 percent.
- Asthma stays declined 35 percent among children 1-17 years between 1997 and 2008, while stays for skin and subcutaneous tissue infections increased 97 percent.
- Appendicitis accounted for 4.8 percent of discharges among children 1-17 years.
- Mood disorders was the third most common diagnosis for children 1-17 and adults 18-44 years.
Older adults:
- Cardiovascular conditions were the most common diagnoses for adults over 44 years old. However, specific diagnoses differed between age groups for older adults:
- Coronary atherosclerosis accounted for 4.1 percent of all discharges for adults 45-64; these stays declined by 27 percent between 1997 and 2008. This condition also ranked fourth for 65-84 year olds (4.2 percent of stays in 2008), with stays declining 40 percent between 1997 and 2008.
- Congestive heart failure (CHF) was the most common condition for adults 65-84 and 85 and older. In 2008, CHF accounted for 4.7 percent of all stays among adults 65-84 and 7.7 percent of all stays among adults 85 and older.
- Cardiac dysrhythmias was the reason for 125,000 hospitalizations (3.9 percent) in 2008 among adults age 85 years and older, an increase of 79 percent since 1997.
- Among adults 85 and older, hospitalizations for septicemia (up 95 percent) and urinary tract infections (up 81 percent) increased at more than twice the rate of all hospitalizations for this age group between 1997 and 2008.
- Musculoskeletal conditions:
- Osteoarthritis more than tripled among adults 45-64 and increased 73 percent among adults 65-84.
- Spondylosis, intervertebral disc disorders, and other back problems increased 51 percent for 45-64 year olds between 1997 and 2008.
All patients:
- Pneumonia was a top five condition for all age groups except 18-44 year olds:
- Hospital stays for pneumonia declined among children (a drop of 39 percent for children less than one and a 19-percent decline for children 1-17 years).
- Pneumonia stays rose among 45-64 year olds (28 percent), but fell among 65-84 year olds (down 13 percent).
- The number of pneumonia stays remained relatively stable for adults 85 years and older.
