National Norms for Hospitalizations Due to Ambulatory Care Sensitive Conditions among Adults in the US.

Ambulatory care sensitive conditions (ACSCs) are acute or chronic health issues that lead to potentially preventable hospitalizations when not treated in the outpatient primary care setting. To describe national hospitalization rates due to ACSCs among adult inpatients in the US. A retrospective cross-sectional analysis of the 2018 US National Inpatient Sample (NIS) dataset from the Healthcare Cost and Utilization Project at the Agency of Healthcare Research and Quality was completed in the year 2022. Participants were adult inpatients from community hospitals in 48 states of the US and District of Columbia. ACSC admission rates were calculated using ICD-10 codes and the Purdy ACSC definition. The admission rates were weighted to the US inpatient population and stratified by age, sex, and race. ACSC hospitalization rates varied considerably across age and average number of hospitalizations varied across sex and race. ACSC hospitalization rates increased with age, male sex, and Native American and Black race. The most common ACSCs were pneumonia, diabetes, and congestive heart failure. Previous studies have emphasized the importance of preventable hospitalizations, however, the national rates for ACSC hospitalizations across all ages in the US have not been reported. The national rates presented will facilitate comparisons to identify hospitals and health care systems with higher-than-expected rates of ACSC admissions that may suggest a need for improved primary care services.

Effect of Massachusetts healthcare reform on racial and ethnic disparities in admissions to hospital for ambulatory care sensitive conditions: retrospective analysis of hospital episode statistics.

To examine the impact of Massachusetts healthcare reform on changes in rates of admission to hospital for ambulatory care sensitive conditions (ACSCs), which are potentially preventable with good access to outpatient medical care, and racial and ethnic disparities in such rates, using complete inpatient discharge data (hospital episode statistics) from Massachusetts and three control states. Difference in differences analysis to identify the change, overall and according to race/ethnicity, adjusted for secular changes unrelated to reform. Hospitals in Massachusetts, New York, New Jersey, and Pennsylvania, United States. Adults aged 18-64 (those most likely to have been affected by the reform) admitted for any of 12 ACSCs in the 21 months before and after the period during which reform was implemented (July 2006 to December 2007). Admission rates for a composite of all 12 ACSCs, and subgroup composites of acute and chronic ACSCs. After adjustment for potential confounders, including age, race and ethnicity, sex, and county income, unemployment rate and physician supply, we found no evidence of a change in the admission rate for overall composite ACSC (1.2%, 95% confidence interval -1.6% to 4.1%) or for subgroup composites of acute and chronic ACSCs. Nor did we find a change in disparities in admission rates between black and white people (-1.9%, -8.5% to 5.1%) or white and Hispanic people (2.0%, -7.5% to 12.4%) for overall composite ACSC that existed in Massachusetts before reform. In analyses limited to Massachusetts only, we found no evidence of a change in admission rate for overall composite ACSC between counties with higher and lower rates of uninsurance at baseline (1.4%, -2.3% to 5.3%). Massachusetts reform was not associated with significantly lower overall or racial and ethnic disparities in rates of admission to hospital for ACSCs. In the US, and Massachusetts in particular, additional efforts might be needed to improve access to outpatient care and reduce preventable admissions.
