Original InvestigationCommunity-Acquired Acute Kidney Injury: A Nationwide Survey in China
Section snippets
Participants and Survey Protocol
The study was approved by the Ethics Committee of Peking University First Hospital, and the requirement for informed consent was waived due to the retrospective nature of the study (2014[729]). The survey protocol has previously been described in detail.5 Altogether in 2013, there were 2,223,230 hospitalized adults (aged ≥ 18 years) from 22 academic hospitals and 22 local hospitals in Mainland China who were screened for suspected AKI based on changes in serum creatinine (Scr) levels through
Overview of Community-Acquired AKI Cases
Among the 374,286 patients who were admitted to the hospital during either of the 2 months studied (January and July 2013), AKI was defined in 7,604 cases, of which 4,136 were identified as community-acquired AKI. The detected rate of community-acquired AKI among adult hospitalizations was 1.11% (4,136 of 374,286), and the proportion of community-acquired AKI cases among all AKI cases was 54.4% (4,136 of 7,604; Tables 1 and 2).
Characteristics of Patients With Community-Acquired AKI
Mean age of patients with CA-AKI was 61.2 ± 17.9 (standard deviation)
Discussion
Systemic reports on community-acquired AKI are limited worldwide.15, 16 The recommended AKI definitions7 focus on the rapid increase in Scr level or a decrease in urine output within a short period and thus can be easily applied to patients who develop AKI during hospitalization, but are less applicable for community-acquired AKI cases in which kidney injury occurs outside hospitals, and the patients may have experienced a sharp increment in Scr levels before admission.1 In the current study,

2022, Kidney MedicineCitation Excerpt :AKI was divided into 2 mutually exclusive categories because of potential differences between inpatient and outpatient AKIs (Fig S1).7 Cases of AKI that developed within 7 days preceding hospitalization, the so-called community-acquired AKI,4-7,28 were categorized with cases of hospital-acquired AKI as “inpatient AKI.” This was done because of the similar mortality risk observed by others after either community-acquired AKI and hospital-acquired AKI and a dissimilar mortality pattern after AKI without hospitalization.7
