SECTION 2: INPATIENT HOSPITAL STAYS BY DIAGNOSIS



HIGHLIGHTS
  • Hospitalizations per 10,000 population for musculoskeletal conditions increased by 15 percent, from 95 stays per 10,000 population in 1997 to 110 stays per 10,000 population in 2009.
  • The rate of stays for circulatory conditions decreased by 13 percent over the 12-year period, falling from 217 stays per 10,000 population in 1997 to 189 stays per 10,000 population in 2009.
  • Liveborn (newborn infant) (4.2 million stays) was the most common diagnosis and accounted for more than 10 percent of all hospital stays. Since 1997, the rate of stays for newborn infants has remained stable (from 139 in 1997 to 135 in 2009 per 10,000 population).
  • Pneumonia (3.0 percent of all stays) and congestive heart failure (2.6 percent) were the second and third most common reasons for hospitalization.
  • The fourth and seventh most frequent principal diagnoses in 2009 (osteoarthritis and septicemia) were not among the most frequent diagnoses in 1997. Between 1997 and 2009, stays per 10,000 population for osteoarthritis increased 95 percent, and stays per 10,000 population for septicemia increased by 78 percent.
  • Mood disorders was ranked seventh in 1997 and fifth in 2009, and increased nearly 20 percent per population over this time period, from 24 to 28 stays per 10,000.
  • Three circulatory diseasesócongestive heart failure, coronary atherosclerosis, and cardiac dysrhythmiasówere among the top ten most frequent principal diagnoses in 2009.
  • In 2009, acute renal failure was the most rapidly growing condition with an increase of 245 percent, from 3.6 to 12.4 stays per 10,000 population.
  • Osteoarthritis was the most common condition for adults 45-64 with an increase of 151 percent in the rate of stays per 10,000 population. Between 1997 and 2009, osteoarthritis increased by 58 percent among adults aged 65-84 and was the second most common condition.
  • Spondylosis, intervertebral disc disorders, and other back problems—the fourth most common condition among 45-64 year olds—remained relatively stable from 1997 to 2009.
  • Three of the most common conditions with Medicaid as the primary payer were pregnancy and childbirth-related: liveborn (newborn infant), trauma to the vulva and perineum due to childbirth, and previous C-section. Altogether, stays for these conditions made up approximately 30 percent of all Medicaid stays.
  • Four of the most common conditions for uninsured hospital stays increased from 1997 to 2009: alcohol-related disorders (36 percent), mood disorders (64 percent), non-specific chest pain (99 percent), and skin and subcutaneous tissue infections (176 percent).
