Brief summary

At one family-medicine practice, an EHR-integrated nurse-led UTI triage tool was associated with more symptom documentation, fewer urine cultures without microscopy, and a decline in asymptomatic-bacteriuria antibiotics from 20% to 3%, with no observed increase in pyelonephritis.

What NurseJet pulled from the source

Researchers used workflow mapping and interviews with 11 nurses to build an EHR-integrated UTI symptom score and triage algorithm for an urban academic family-medicine practice. A 15-month pre-post interrupted time-series evaluation examined adoption, documentation, urine testing, antibiotic prescribing, and 30-day pyelonephritis. All nurses adopted the tool, fidelity was 77.8%, and usability was rated highly. Documentation of at least two UTI-specific symptoms increased at implementation and continued improving by 2.4 percentage points per month (95% CI 0.1 to 4.7). Urine cultures ordered without microscopy had a slope of -5.5 percentage points per month (95% CI -7.9 to -3.2). Antibiotic prescribing for asymptomatic bacteriuria fell from 20% to 3% (P=.003), with no observed increase in 30-day pyelonephritis. The findings support a nurse-led stewardship workflow, but the single-practice pre-post design cannot by itself prove that the tool caused each change.

Why this matters for nurses

Urinary complaints can trigger reflex testing and antibiotics even when defining symptoms are absent. This study matters for nurses because it places structured symptom assessment inside the triage workflow and links better documentation with fewer low-value cultures and less treatment of asymptomatic bacteriuria.

Bedside takeaway

Be aware that after a nurse-led UTI triage tool was introduced, symptom documentation increased and asymptomatic-bacteriuria antibiotic use fell from 20% to 3%, with no observed rise in 30-day pyelonephritis.

Key takeaways

The mixed-methods study developed an EHR-integrated symptom score and triage algorithm with 11 family-medicine nurses.
All nurses adopted the tool, with 77.8% fidelity and high reported usability.
Symptom documentation increased while urine cultures ordered without microscopy declined over the 15-month evaluation.
Antibiotic treatment of asymptomatic bacteriuria fell from 20% to 3%, with no observed increase in 30-day pyelonephritis.

Practice implications

Outpatient triage teams can use this study when evaluating locally approved EHR prompts that require symptom documentation before urine testing. Any tool should preserve assessment and escalation for suspected upper-tract infection and should not replace local diagnostic, prescribing, or scope-of-practice rules.

Limitations & cautions

The study involved one urban academic family-medicine practice and only 11 nurses. Its pre-post design cannot exclude secular trends or prove causation, and results may not transfer to inpatient, emergency, long-term-care, or differently configured EHR settings without local evaluation.

Renal failure (PubMed)Sep 7, 2026Research Article

A single-center retrospective cohort found that approximately one quarter of laboratory-defined acute kidney injury cases on internal medicine wards were not documented, particularly when maximal creatinine was lower.

Med-SurgAI summaryReview source

Research ArticleResearchQuality ImprovementAI summary · original source linked below

Among 161 adult hospitalizations meeting serum-creatinine criteria for acute kidney injury, 39 cases (24.2%) were undocumented. Length of stay and in-hospital mortality did not differ significantly by documentation status.

Key takeaways

In the 149 hospitalizations with a demonstrable creatinine change, 33 cases (22.1%) were undocumented.
Higher maximal creatinine was associated with lower adjusted odds of underdocumentation.
The study did not test whether a detection or documentation intervention improves care or outcomes.

Why this matters on shift

A smaller creatinine rise may receive less attention even when it meets the study's laboratory definition of acute kidney injury, which can affect how renal risk is communicated across the inpatient team.

Bedside takeaway

Trend ordered renal-function results and communicate clinically important changes through local escalation and documentation workflows.

Nursing implications

Trend ordered renal-function results and communicate clinically important changes through the care team according to local escalation and documentation workflows.

Limitations & cautions

Abstract-only summary. This was a retrospective, single-center study of 161 hospitalizations; urine-output criteria and reliable preadmission creatinine values were unavailable, and the reference creatinine method may affect case classification.

In the pragmatic TARGET-D randomized trial, vitamin D dosing titrated to a serum target did not significantly reduce the composite of death, recurrent myocardial infarction, heart-failure hospitalization, or stroke after myocardial infarction.

Telemetry Med-SurgAI summaryReview source

Research ArticleResearchMedication SafetyPatient EducationAI summary · original source linked below

Among 630 participants followed for an average of 4.2 years, major cardiovascular events occurred in 15.7% with targeted vitamin D management and 18.4% with usual care (hazard ratio 0.85, 95% CI 0.58 to 1.24; P=0.40).

Key takeaways

At baseline, 87% of participants had a 25-hydroxyvitamin D level of 40 ng/mL or lower.
The primary composite outcome and the individual outcomes of death, heart-failure hospitalization, and stroke were not significantly different.
A lower recurrent-MI rate was a secondary finding and should not override the nonsignificant primary result.

Why this matters on shift

The trial cautions against presenting targeted vitamin D supplementation as a proven strategy for reducing major cardiovascular events after myocardial infarction.

Bedside takeaway

Present vitamin D as prescribed supplementation, not as a replacement for established post-MI secondary prevention.

Nursing implications

Reinforce the prescribed secondary-prevention plan and avoid implying that vitamin D replaces therapies with established post-MI benefit.

Limitations & cautions

Abstract-only summary. The trial included 630 participants, 78.1% were men, the primary confidence interval included benefit and no benefit, and individual secondary outcomes were not the primary endpoint.

A prospective Dutch nursing-home cohort found clinically important differences in illness burden across respiratory viruses, with influenza and human metapneumovirus standing out.

Geriatrics Med-SurgAI summaryReview source

Research ArticleResearchInfection ControlAI summary · original source linked below

Among 3,195 residents at 15 nursing homes, 526 suspected acute respiratory-infection episodes were recorded and a virus was identified in 291. Influenza A was associated with delayed recovery, oxygen use, and threefold secondary-bacterial-pneumonia risk; hMPV was linked to fourfold more time in bed.

Key takeaways

SARS-CoV-2, influenza A, rhinovirus or enterovirus, and RSV were the most frequently identified viruses.
hMPV and RSV tended to have higher odds of moderate or severe disease.
Virus-specific patterns were associations from a cohort, not randomized comparisons.

Why this matters on shift

Frailty can amplify respiratory-infection consequences, and the causative virus may help anticipate recovery, oxygen, mobility, and secondary-infection needs.

Bedside takeaway

Trend oxygen needs, mobility, recovery, and secondary-pneumonia signs during nursing-home respiratory infections.

Nursing implications

During outbreaks or suspected infection, trend oxygen needs, mobility and time in bed, recovery, and signs of bacterial pneumonia according to facility protocols.

Limitations & cautions

Abstract-only summary. Data came from 15 Dutch nursing homes, the overall suspected-infection risk estimate was imprecise, and virus-outcome comparisons may be affected by confounding and small subgroup counts.
