Drug Overdose Hospitalizations Linked to Higher Acute Kidney Injury Rates in Older Adults and Men
A CDC study reveals that acute kidney injury (AKI) is more prevalent among older adults and men hospitalized due to drug overdoses, with rising rates from 2016 to 2022. Despite a recent decline in AKI incidence, severe inpatient courses remain common, especially among younger patients. The findings highlight the need for improved kidney monitoring and post-hospital care.
A CDC study analyzing U.S. hospitalizations from 2016 to 2025 reveals that acute kidney injury (AKI) is significantly more common among older adults and men hospitalized due to drug overdoses, with AKI documented in 34.5% of 1.3 million overdose-related hospitalizations. Among subgroups, men had a 38.1% AKI rate, compared to 29.4% for women; patients aged 65 and older had a 37.4% rate, while those under 24 had 28.2%. Despite an overall decline in AKI incidence from 2022 to 2025 (annual percentage change of −5.11%), severe inpatient courses—defined as requiring intensive care or leading to complications—remained high, affecting 60.9% of AKI patients overall, with the highest rates among those under 24 (68.1%). The study, published in the Morbidity and Mortality Weekly Report, notes that while overdose mortality has recently declined, nonfatal complications like AKI are still prevalent and may be rising in severity among younger patients. The research was led by Sola Han, Pharm.D., Ph.D., of the CDC’s Atlanta office, who emphasizes the need for early detection and sustained kidney care post-discharge to prevent long-term damage.
The findings emerge amid growing concern over the opioid crisis and its broader health impacts beyond mortality. While earlier reports have highlighted rising overdose deaths, this study shifts focus to secondary complications that may persist even after recovery from the acute event. The CDC’s analysis builds on prior work showing organ system stres
This study could influence clinical protocols in emergency and critical care settings by reinforcing the need for routine kidney function monitoring during and after overdose hospitalizations, particularly for older men and younger patients. Hospitals may begin integrating standardized AKI screening into post-overdose care pathways, potentially reducing long-term renal complications. The findings may also prompt insurers and public health agencies to expand coverage for follow-up nephrology visits and rehabilitation services, especially in regions with high overdose rates. Comparable to the earlier recognition of post-traumatic stress disorder (PTSD) as a common consequence of combat exposure, AKI after overdose could become a recognized secondary condition requiring structured care. If adopted widely, such measures may reduce future healthcare burdens linked to chronic kidney disease. However, whether these recommendations will translate into policy changes or improved patient outcome
