AKI was defined as a serum creatinine increase of&lt;!--&gt; &lt;!--&gt;≥0.3&lt;!--&gt; &lt;!--&gt;mg/dL. A gated recurrent unit (GRU)-based recurrent neural network (RNN) was trained on 85% of the data, and then tested on the remaining 15%. Model performance was evaluated with precision, recall, negative predictive value, and area under the curve. We used an artificial neural network to determine risk factor importance.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;There were 14,480 patients, 18,180 admissions, and 37,300 high-nephrotoxin exposure events meeting inclusion criteria. In the testing cohort, 29% of exposures developed AKI within 48 hours. The RNN-GRU model predicted AKI with a precision of 0.60, reducing the number of false alerts from 2.5 to 0.7 per AKI case. Lowest hemoglobin, lowest blood pressure, and highest white blood cell count were the most important variables in the artificial neural network model. Acyclovir, piperacillin-tazobactam, calcineurin inhibitors, and angiotensin-converting enzyme inhibitor/angiotensin receptor blockers were the most important medications.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Limitations&lt;/h3&gt;&lt;div&gt;Clinical variables and medications were not exhaustive, drug levels or dosing were not incorporated, and Iowa’s racial makeup may limit generalizability.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;Our RNN-GRU model substantially reduced the number of false alerts for nephrotoxic AKI, which may facilitate NINJA translation to adult hospitals by providing more targeted intervention.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Plain-Language Summary&lt;/h3&gt;&lt;div&gt;Nephrotoxic acute kidney injury (AKI) is common and can potentially be prevented through preemptive adjustments of medications, as demonstrated by the success of the nephrotoxic injury negated by just-in time action (NINJA) program in pediatric populations.

We assessed longitudinal patterns of antihypertensive drug prescription and systolic BP.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Study Design&lt;/h3&gt;&lt;div&gt;Prospective observational cohort study.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Setting &amp; Population&lt;/h3&gt;&lt;div&gt;In total, 2,755 hypertensive patients with CKD stages 3-4, receiving care from a nephrologist, from the French CKD–Renal Epidemiology and Information Network (CKD-REIN cohort study).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Exposure&lt;/h3&gt;&lt;div&gt;Patient factors, including sociodemographic characteristics, medical history, and laboratory data, and provider factors, including number of primary care physician and specialist encounters.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Outcomes&lt;/h3&gt;&lt;div&gt;Changes in antihypertensive drug-class prescription during follow-up: add-on or withdrawal.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Analytical Approach&lt;/h3&gt;&lt;div&gt;Hierarchical shared-frailty models to estimate hazard ratios (HR) to deal with clustering at the nephrologist level and linear mixed models to describe systolic BP trajectory.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;At baseline, median age was 69 years, and mean estimated glomerular filtration rate was 33&lt;!--&gt; &lt;!--&gt;mL/min/1.73 m². In total, 66% of patients were men, 81% had BP&lt;!--&gt; &lt;!--&gt;≥&lt;!--&gt; &lt;!--&gt;130/80&lt;!--&gt; &lt;!--&gt;mm Hg, and 75% were prescribed&lt;!--&gt; &lt;!--&gt;≥2 antihypertensive drugs. During a median 5-year follow-up, the rate of changes of antihypertensive prescription was 50 per 100 person-years, 23 per 100 for add-ons, and 25 per 100 for withdrawals. After adjusting for risk factors, systolic BP, and the number of antihypertensive drugs, poor medication adherence was associated with increased HR for add-on (1.35, 95% confidence interval [CI], 1.01-1.80), whereas a lower education level was associated with increased HR for withdrawal (1.23, 95% CI, 1.02-1.49) for 9-11 years versus&lt;!--&gt; &lt;!--&gt;≥12 years. More frequent nephrologist visits (≥4 vs none) were associated with higher HRs of add-on and withdrawal (1.52, 95% CI, 1.06-2.18; 1.57, 95% CI, 1.12-2.19, respectively), whereas associations with visit frequency to other physicians varied with their specialty. Mean systolic BP decreased by 4&lt;!--&gt; &lt;!--&gt;mm Hg following drug add-on but tended to increase thereafter.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Limitations&lt;/h3&gt;&lt;div&gt;Lack of information on prescriber and drug dosing.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;In patients with CKD and poor BP control, changes in antihypertensive drug prescriptions are common and relate to clinician preferences and patients’ tolerability.
