Epidemiology of Community-Acquired Acute Kidney Injury Among US Veterans.

RATIONALE & OBJECTIVE: Community-acquired acute kidney injury (CA-AKI) develops outside of the hospital and is the most common form of AKI globally. National estimates of CA-AKI in the United States are absent due to limited availability of laboratory data. This study leverages national data from the Veterans Health Administration (VA) to estimate incidence and risk factors of CA-AKI. STUDY DESIGN: Retrospective cohort study using national VA administrative and laboratory data to assess cumulative CA-AKI incidence. SETTING & PARTICIPANTS: VA primary care patients in 2013-2017 with recorded outpatient serum creatinine (Scr) and no history of chronic kidney disease≥stage 5. PREDICTOR: Sociodemographics, comorbidities, medication use, and health care utilization. OUTCOME: Annual incidence of CA-AKI defined as a≥1.5-fold relative increase in Scr on either a subsequent outpatient Scr or inpatient Scr obtained within ≤24 hours of admission. ANALYTICAL APPROACH: We calculated the relative change in Scr within 12 months of an outpatient Scr value. A Cox model was used to estimate the association between CA-AKI and baseline characteristics, accounting for repeated measurements. RESULTS: Of approximately 2.5 million eligible veterans each year, the cumulative incidence of CA-AKI was approximately 2% annually. Only 27% of CA-AKI was detected at hospital admission. In adjusted analyses, high health care utilization, chronic illness, cancer, rural location, female sex, and use of renin-angiotensin aldosterone system inhibitors or diuretics were associated with increased CA-AKI risk (all, HR>1.20). LIMITATIONS: Limited generalizability of results outside a veteran population, lack of a standardized definition for CA-AKI, and possibility of surveillance bias and misclassification. CONCLUSIONS: CA-AKI affects 1 of every 50 US veterans annually. With less than a third of CA-AKI observed in the inpatient hospital setting, reliance on inpatient evaluation of AKI suggests significant underrecognition and missed opportunities to prevent and manage the long-term consequences of AKI.

What Do Acute Kidney Injury Survivors Want to Know About Their Condition: A Qualitative Study.

Rationale & Objective: Acute kidney injury (AKI) in the hospital often occurs with other serious illnesses that take medical priority. Despite a persistent risk of adverse outcomes following hospital discharge, AKI survivors often receive inadequate education about how best to mitigate risks once home. We sought to identify AKI survivors' perceived barriers to shared and informed decision-making regarding their AKI diagnosis and self-management. Study Design: Semistructured phone interviews were used to assess patients' perceived barriers and facilitators to AKI self-management after a hospital-related AKI event. Setting & Participants: AKI survivors discharged from Duke University Hospital in Durham, NC, were recruited for interviews to discuss their AKI experiences. Those who received dialysis for AKI were excluded because their perceptions of AKI care were hypothesized to be much different from those of patients not requiring dialysis. Analytical Approach: Twenty-four interviews were conducted between May and August 2018. Interviews were recorded, transcribed, and analyzed by study team members to identify common themes and discrepancies and reach a final consensus. Results: Five consistent themes emerged after thematic saturation: (1) patients were unaware of their AKI diagnosis; (2) patients lacked information about AKI and how to manage it at home; (3) patients identified a lack of understanding about AKI; (4) patients were concerned about dialysis; and (5) patients wanted to know how to prevent AKI in the future. Limitations: Limitations include recruitment from a single center, all study participants receiving a nephrology consultation, and several patients being unable to participate because of persistent illness following hospitalization. Conclusions: AKI survivors are unaware of their diagnosis, receive suboptimal education while hospitalized, and are not equipped with tools to mitigate risks following discharge. Patient-centered interventions promoting AKI awareness and self-management may improve long-term outcomes for high-risk AKI survivors.

Managing attention-deficit/hyperactivity disorder in children and adolescents.

Attention-deficit/hyperactivity disorder (ADHD) is the most frequently diagnosed neurodevelopmental disorder; 6.4 million children and adolescents have been diagnosed with ADHD as of 2011. However, only 3.5 million children and adolescents are taking medication for ADHD. Adolescents with ADHD are much less willing to pursue or adhere to medication or psychosocial therapy, often because of their perceptions of side effects or perceived value of treatment, which places them at greater risk for difficulties at school, work, and home environments. Providing adolescents with increased autonomy through patient-centered approaches can increase their involvement and ability to manage their ADHD symptoms and treatment.
