Objective:
To assess the impacts of flooding on access to dialysis care and compare current and future risk from flood inundation and isolation.
Design:
A cross-sectional study. Maps were generated in ArcGIS using the 100-year flood plain, transportation networks, and dialysis center locations, showing spatial flood risks for dialysis center locations in the State of Delaware.
Main Outcome Measure:
Number of roads, intersections, and dialysis centers closed due to flood inundation or isolation and population expected to be impacted.
Results:
Six dialysis facilities would be flooded in a flooding event, and three additional facilities would be isolated. The spatial distribution of dialysis care access is inequitable across the state and among socially vulnerable groups.
Conclusions:
Mapping the impact of flooding on access to dialysis center care in Delaware is important for identifying geographic areas and socially vulnerable populations at high risk for dialysis service disruptions in flooding events.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

01:11Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
01:17Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
