Avoidable hospitalizations refer to admissions for acute or chronic illnesses that could have been prevented with adequate management and treatment in outpatient settings. These hospitalizations are often tracked as markers of health system efficiency, as they reflect the overuse of hospitals as a primary source of care and can place a significant financial burden on patients, insurance providers, and hospitals. The Agency for Healthcare Research and Quality (AHRQ) utilizes Prevention Quality Indicators (PQIs) to measure potentially avoidable hospitalizations at the state and county levels. These indicators provide insights into the accessibility and quality of outpatient primary care services and help identify areas for improvement in healthcare services. By analyzing data on hospitalization rates, income, race, and ethnicity, public health officials can develop strategies to reduce disparities and improve health outcomes for various populations.

Preventable hospitalizations place financial burdens on patients, insurance providers, and hospitals
The Agency for Healthcare Research and Quality (AHRQ) defines potentially avoidable hospitalizations as admissions for acute and chronic conditions that could have been avoided through adequate management and treatment in outpatient settings. These include conditions such as perforated appendix, hypertension, diabetes, and asthma. The rates of these preventable hospitalizations vary across different demographic groups and are influenced by factors such as race, ethnicity, income, and access to primary care.
The financial burden of preventable hospitalizations is significant for patients, particularly those from lower-income communities. Outpatient care for acute or chronic conditions can prevent complications, worsening diseases, and the need for hospitalization, reducing the financial strain on patients. Preventable hospitalizations also impact insurance providers, as they are often responsible for covering the costs of these admissions, which can be substantial.
Hospitals also bear the brunt of preventable hospitalizations, as they incur the costs of treating these patients. Additionally, hospitals may face challenges in managing bed occupancy and resource allocation due to preventable admissions. Reducing preventable hospitalizations can help alleviate the financial strain on hospitals and improve the efficiency of the healthcare system.
To address the issue of preventable hospitalizations, it is essential to improve access to and quality of outpatient primary care services. This includes early intervention and continuous care for patients with acute or chronic conditions, as well as addressing social determinants of health such as income and race/ethnicity. By reducing preventable hospitalizations, patients, insurance providers, and hospitals can avoid unnecessary financial burdens and improve overall health outcomes.

Differences in rates of preventable hospitalizations by race and ethnicity
There are significant disparities in preventable hospitalization rates among different racial and ethnic groups in the United States. These disparities are influenced by various factors, including income, access to healthcare, and underlying health conditions.
In 2007, African Americans had the highest rate of preventable hospitalizations among all ethnic groups in California, at about 13%. This was followed by whites (11%), Latinos (8.6%), Asians (6.7%), and Native Americans (3.9%). Additionally, African Americans had higher rates of disease for 14 out of 16 medical conditions used to measure access to outpatient care.
From 2005 to 2013, the overall rate of avoidable hospitalizations for hypertension increased from 48.4 to 57.8 per 100,000 population. Hypertension is a critical risk factor for cardiovascular disease, which is the leading cause of premature death among African Americans compared to whites. In 2013, rates of potentially avoidable hospitalizations for all conditions were higher for Blacks than Whites and lower for Asians and Pacific Islanders (APIs).
Income also plays a significant role in preventable hospitalization rates. Individuals living in low-income neighborhoods often have limited access to quality healthcare and are more likely to be hospitalized for conditions that could have been managed through primary care. Additionally, race and ethnicity intersect with income to further impact hospitalization rates. For example, during 2009, if non-Hispanic whites had the same hospitalization rate as A/PIs (Asian/Pacific Islanders), they would have had 700,000 fewer hospitalizations and saved $7.7 billion in costs.
While there have been efforts to reduce preventable hospitalizations, such as improving outpatient care and addressing social determinants of health, disparities across racial and ethnic groups persist. These disparities contribute to higher healthcare costs and highlight the need for targeted interventions to improve access to quality healthcare for vulnerable communities.

Differences in rates of preventable hospitalizations by income
Preventable hospitalizations are admissions to a hospital for acute illnesses or worsening chronic conditions that could have been avoided with successful management by primary care providers in outpatient settings. These hospitalizations are often tracked as markers of health system efficiency and can help identify potential cost savings.
From 2005 to 2017, there was a significant decrease in preventable hospitalizations for bacterial pneumonia and chronic obstructive pulmonary disease (COPD) and asthma. However, there was an increase in short-term diabetes complications. The rate of preventable hospitalizations among adults aged 18 and older was also found to vary by income quartile, with the lowest-income communities having higher rates of preventable hospitalizations than the wealthiest communities.
The 2011 CHDIR report by the CDC was the first to examine disparities across a wide range of diseases, behavior risk factors, environmental exposures, social determinants, and healthcare access. The report aimed to raise awareness of differences in race/ethnicity and income among persons with excess potential preventable hospitalizations and prompt actions to reduce these disparities.
In 2013, rates of potentially avoidable hospitalizations for all conditions were higher for Blacks than Whites and lower for Asians and Pacific Islanders (APIs) than Whites across all income groups. Specifically, the rate was 1536.3 per 100,000 population for Whites in the lowest-income group and 1810.9 per 100,000 population for Blacks in the highest-income group.
The Affordable Care Act and Medicaid expansion in 2014 contributed to a decrease in preventable hospitalization rates, particularly for older adults with chronic obstructive pulmonary disease, asthma, and bacterial pneumonia. These reductions may be attributed to improved access to health insurance and primary care management.

The relationship between avoidable hospitalization and accessibility to primary care
Avoidable hospitalization (AH) is a widely studied phenomenon, used as a possible measure of the performance of primary health care (PHC). It is defined as a hospitalization that could have been prevented through timely and effective utilization of outpatient care. These include acute illnesses (e.g. dehydration, pneumonia, appendicitis with complications) and worsening chronic conditions (e.g. diabetes, asthma, hypertension, chronic obstructive pulmonary disease) that could have been successfully managed by primary care providers.
Studies have found mixed results when examining the relationship between the efficiency and quality of PHC and AH. However, a systematic review of 51 papers revealed that 72.5% showed a significant inverse association between PHC accessibility and AH rates. This indicates that areas with greater access to PHC tend to have lower hospitalization rates for ambulatory care sensitive conditions (ACSCs).
The relationship between AH and PHC accessibility is influenced by various factors, including income levels, insurance status, race, ethnicity, and socioeconomic status. For example, in 2013, rates of potentially avoidable hospitalizations were higher for Blacks than Whites and lower for Asian and Pacific Islanders (APIs) across all income groups. Additionally, populations with higher rates of preventable hospitalizations include women compared to men, and Black and American Indian/Alaska Native adults compared to APIs.
The occurrence of AH can be used as an indicator of the quality of diagnosis, treatment, and chronic disease management in primary care. By tracking AH rates, healthcare systems can identify potential cost savings and improve health system efficiency. However, it is important to consider contradictions that may arise when interpreting the relationship between AH and PHC quality at the individual level.
In conclusion, while the relationship between AH and PHC accessibility is complex and influenced by various factors, most studies confirm the expected inverse relationship between them. This suggests that improving access to quality PHC can help reduce AH rates and improve health outcomes and healthcare costs.

The cost of potentially preventable hospitalizations and potential cost savings
Potentially preventable hospitalizations refer to inpatient stays for treating ambulatory care-sensitive conditions (ACSCs) that could have been avoided through timely and quality primary and preventive care. These include acute illnesses like dehydration and worsening chronic conditions like diabetes, which may not require hospitalization if managed effectively by primary care providers.
The cost of potentially preventable hospitalizations can be substantial, with estimates suggesting that in 2017, preventable hospitalizations cost the United States $33.7 billion, with the majority of costs attributed to chronic conditions such as heart failure, diabetes, and chronic obstructive pulmonary disease. These hospitalizations place a financial burden on patients, insurance providers, and hospitals, and they are often tracked as markers of health system efficiency.
Reducing potentially preventable hospitalizations has become a priority for policymakers and payers. By analyzing data on these hospitalizations, communities can identify potential cost savings. For example, in 2007, preventable hospitalizations among Hispanics cost $4.2 billion, but with improvements in primary care, these costs could have been reduced to $3.3 billion, resulting in savings of $900 million.
The Agency for Healthcare Research and Quality (AHRQ) has developed Prevention Quality Indicators (PQIs) and Pediatric Quality Indicators (PDIs) to identify hospitalizations for ACSCs. These indicators provide insights into the volume and costs of potentially preventable inpatient stays, helping to identify areas where changes to the healthcare delivery system could improve patient outcomes and reduce costs.
Additionally, disparities in potentially preventable hospitalizations exist across different racial and ethnic groups, with higher rates among Black and American Indian/Alaska Native adults compared to Asian/Pacific Islander adults. Addressing these disparities can help reduce the overall number of preventable hospitalizations and improve health equity.
