Hospitalization for Total Knee Replacement Among Inpatients Aged 45 and Over: United States, 2000–2010

September 4, 2015

In 2010, total knee replacement was the most frequently performed inpatient procedure on adults aged 45 and over. In the 11-year period from 2000 through 2010, an estimated 5.2 million total knee replacements were performed. Adults aged 45 and over comprised 98.1% of those surgeries.

An NCHS report uses data from the National Hospital Discharge Survey to present trends in the rate of hospitalizations for total knee replacement, mean age at hospitalization, and discharge status for inpatients aged 45 and over from 2000 through 2010.

Key Findings from the Report:

  • The rate of total knee replacement increased for both men (86%) and women (99%) aged 45 and over from 2000 through 2010.
  • For both 2000 and 2010, women had a higher rate of total knee replacement (33.0 and 65.5 per 10,000 population, respectively) than men (24.3 and 45.3 per 10,000, respectively).
  • The mean age at total knee replacement decreased from 2000 through 2010 for both men and women aged 45 and over.
  • Higher percentages of men and women aged 45 and over who were hospitalized for total knee replacement were discharged home in 2010 (69.8% and 54.1%) than in 2000 (53.5% and 40.8%).
  • In both 2000 and 2010, a lower percentage of women aged 45 and over (40.8% and 54.1%, respectively) were discharged home after total knee replacement than men aged 45 and over (53.5% and 69.8%, respectively).

A brief look at heart disease

February 25, 2009

As a farewell to “American Heart Month,” here’s a brief synopsis of why the heart and its health affects so many of us:

  • Heart disease is the nation’s leading cause of death, responsible for 629,191 deaths in 2006 (National Vital Statistics System, 2006).
  • Heart disease is the nation’s leading diagnosis for hospitalization, at 4.2 million (National Hospital Discharge Survey, 2006).
  • Over 24 million visits to physician offices in 2006 resulted in a diagnoses of heart disease (National Ambulatory Medical Care Survey, 2006).
  • About 11% of U.S. adults have ever been told by a doctor or other health professional they had heart disease (National Health Interview Survey, 2007).
  • About one in six Americans aged 20 years and over has elevated blood pressure and one in four has hypertension (National Health and Nutrition Examination Survey, 2001-2004).

Anti-depressant Use

August 10, 2007

CNN recently ran a story that has gained some attention. It is entitled CDC: Antidepressants most prescribed drugs in U.S.

[…]According to a government study, antidepressants have become the most commonly prescribed drugs in the United States. They’re prescribed more than drugs to treat high blood pressure, high cholesterol, asthma, or headaches. CNN’s Elizabeth Cohen discusses the CDC study on antidepressants »

In its study, the U.S. Centers for Disease Control and Prevention looked at 2.4 billion drugs prescribed in visits to doctors and hospitals in 2005. Of those, 118 million were for antidepressants.

High blood pressure drugs were the next most-common with 113 million prescriptions.

The use of antidepressants and other psychotropic drugs — those that affect brain chemistry — has skyrocketed over the last decade.

Adult use of antidepressants almost tripled between the periods 1988-1994 and 1999-2000.

Between 1995 and 2002, the most recent year for which statistics are available, the use of these drugs rose 48 percent, the CDC reported.

The data for this report comes from our flagship publication Health, United States and in the 2006 edition is found at Table 92. This publication is an invaluable resource for anyone writing about health issues. If you are just interested in the drug use data click here.

Hip and Knee Replacement Surgery

July 6, 2007

Pioneered by Sir John Charnley in the 1960s, hip and knee replacement surgery has offered a markedly improved quality of life to thousands of people who would otherwise have had their mobility severely limited. Since 1996 the rate of persons receiving total hip replacement has increased by 52% and the rate of those receiving total knee replacement has more than doubled.

 Data from the Hospital Discharge Survey document the increasing number of these surgeries is here.
