Background

Community acquired acute kidney injury (AKI-CA)is defined in patients who, at the time of admission to the hospital, present criteria for acute kidney injury diagnosis. Older adults are recognized as a vulnerable population for the development of AKI. The objective of this study was to determine the risk factors and the prognosis at one year follow-up of older adult’s patients suffering from AKI-CA.

Methods

Cohort study in patients with ≥65 years old admitted in the emergency room, from March to May of 2018. The AKI-CA was according to the criteria of KDIGO 2012. The groups were compared using the Student's t-distribution or the X2 distribution depending on the type of variable, logistic regression was performed for OR, and a Cox regression for HR and survival with IC 95% and p ≤0.05.

Results

A total of 221 patients that satisfied the inclusion criteria, the average age was 75.1±7.6, the 44% (97) were men. The incidence of the AKI-CA was 58.8% being more common in patients with sepsis (p< 0.001), this was the principal associated factor with the development AKI-CA (OR: 3.52, IC95% 1.6-7.1). It was noticed that the highest stage of the AKI occurs in patients with previous chronic kidney disease (AKI1: 6.4% AKI2: 5.7% AKI 3: 41.2 % p< 0.001), or presence of sepsis (AKI1: 50.7% AKI2: 55.9% AKI 3: 57.1 % p= 0.009). It was not identified increase in risk of inpatient's mortality in patients with AKI-CA. In contrast, a relation between them was noticed after one year follow-up (Figure 1).

Conclusion

Older adults patients that suffer AKI-CA exhibit worst outcomes after one year follow up.
