Importance: Urinary tract infection (UTI) is common in ambulatory care settings and the primary reason for antibiotic prescribing. Despite several guidelines focused on the type and duration of antibiotics prescribed for treating UTI, there is limited outpatient guidance on how to best triage patients with presumed UTI.

Objective: To assess the appropriateness of different triage and management recommendations involving empiric antibiotics, urine testing strategies, and visit types and how these recommendations vary by patient sex, age, presenting symptoms, and clinical history.

Evidence review: Using the RAND/UCLA Appropriateness Method, a 13-member multidisciplinary panel (physicians, advanced practice providers, and nurses) performed a scoping review of the literature publications from 2009 to June 2024 and rated the appropriateness of 136 clinical scenarios (48 for women, 49 for men, and 39 scenarios not specific to sex) with up to 9 management strategies per scenario for a total of 1094 scenarios. For each scenario, experts rated the appropriateness of empiric treatment, types of urine testing, and triage to visit type (in-person, virtual, or none) as appropriate (ie, benefits outweigh risks), inappropriate, or of uncertain appropriateness. Appropriateness ratings were summarized into 2 groups: nonpregnant adult women and adult men.

Findings: Major recommendations based on symptoms included (1) same-day in-person evaluation if symptoms were concerning for pyelonephritis, complicated cystitis, or urinary obstruction; (2) a visit if additional nonurinary symptoms were present (ie, diarrhea, genital discharge, or cough); (3) neither urine testing nor empiric treatment solely due to a change in urine color or appearance without other bladder (cystitis) symptoms; (4) empiric treatment without testing or a visit, for women, if there were new classic cystitis symptoms of dysuria, urinary frequency, urgency, or suprapubic pain without risks for antibiotic resistance; (5) urinalysis with culture (ideally reflexed to culture) before taking first antibiotic dose for women at risk of antibiotic resistance (eg, recent antibiotic treatment for UTI or recurrent UTIs) and all men; and (6) empiric treatment considered for patients with barriers to obtaining timely urine testing or visits.

Conclusions and relevance: The appropriateness of empiric antibiotics, urine testing, and different clinical evaluation options were defined for adults presenting with concerns for UTI in common ambulatory triage settings, including telehealth. These criteria for ambulatory triage of suspected UTI symptoms in adults are anticipated to help standardize and improve the appropriateness of empiric antibiotic prescribing, urine testing, and visit type triage.

Importance Globally, 968 350 new cases and 659 853 deaths from gastric cancer were reported in 2022. In the US, 30 300 new cases and 10 780 deaths were estimated in 2025.

Observations Gastric cancer is more common in men, and the median age at diagnosis is 68 years. Most gastric cancers (>90%) are adenocarcinomas. Worldwide, 85% of cases arise from the stomach body or antrum and 15% from the cardia. In the US, more than 90% of patients diagnosed with gastric cancer present with symptoms such as weight loss and abdominal pain. At presentation, approximately 13% have localized disease (limited to the stomach), 15% to 25% have locally advanced disease, defined as a tumor that has spread to regional lymph nodes, and 35% to 65% have metastatic disease. Helicobacter pylori infection is a treatable risk factor associated with 90% of gastric body and antrum cancers globally. Additional modifiable risk factors include smoking, alcohol, obesity, and salt intake. In countries with high incidence such as Japan and Korea, routine endoscopic screening beginning at age 40 years is associated with improved survival. Diagnosis is made by endoscopic biopsy. Patients with localized gastric cancer are treated with surgical resection and have a 5-year relative survival rate of 75% with treatment. Patients with more advanced-stage disease should receive gastrectomy, perioperative chemotherapy with 5-fluorouracil, oxaliplatin, and docetaxel and immunotherapy (durvalumab). Metastatic or unresectable disease may be treated with chemotherapy, immunotherapy, and/or targeted therapy depending on biomarkers, including programmed cell death ligand 1 (PD-L1), human epidermal growth factor receptor 2 (ERBB2; formerly HER2 or HER2/neu), and claudin-18, isoform 2 (CLDN18.2). For PD-L1–expressing gastric cancer, adding immune checkpoint inhibitors, such as nivolumab and pembrolizumab, is associated with an additional 3 months of survival when compared with chemotherapy alone. For gastric cancers overexpressing the ERBB2 or CLDN18.2 proteins, the addition of trastuzumab or zolbetuximab, respectively, is associated with an additional 3 to 4 months’ survival. Early supportive care focusing on symptom management and on nutritional and psychosocial support is associated with 3 months of survival benefit. Less than 10% of patients with metastatic gastric cancer survive more than 5 years.

Conclusions and Relevance Approximately 30 300 new cases of gastric cancer are diagnosed annually in the US. Localized gastric cancer is treated with gastrectomy, and locally advanced disease is treated with surgery and chemoimmunotherapy. For patients with unresectable or metastatic gastric cancer, chemotherapy with immune checkpoint inhibitors and targeted therapies such as trastuzumab or zolbetuximab improves survival by several months.

Importance: While in short supply and high demand, ambulatory care clinicians spend more time on administrative tasks and documentation in the electronic health record than on direct patient care, which has been associated with burnout, intention to leave, and reduced quality of care.

Objective: To examine whether ambient AI scribes are associated with reducing clinician administrative burden and burnout.

Design, setting, and participants: This quality improvement study used preintervention and 30-day postintervention surveys to evaluate the use of the same ambient AI platform for clinical note documentation among ambulatory care physicians and advanced practice practitioners of 6 academic and community-based health care systems across the US. Clinicians were recruited by the health systems' digital health leaders; participation was voluntary. The study was conducted between February 1 and October 31, 2024.

Exposure: Use of an ambient AI scribe for 30 days.

Main outcomes and measures: The primary outcome was change in self-reported burnout, estimated using hierarchical logistic regression. Secondary outcomes of burnout evaluated were changes in note-related cognitive task load, focused attention on patients, patient understandability of notes, ability to add patients to the clinic schedule if urgently needed, and time spent documenting after hours. Outcome measures were linearly transformed to 10-point scales to ease interpretation and comparison. Differences between preintervention and postintervention scores were determined using paired t tests.

Results: Of the 451 clinicians enrolled, 272 completed the preintervention and postintervention surveys (60.3% completion rate), and 263 with direct patient care in ambulatory clinics (mean [SD] years in practice, 15.1 [9.3]; 141 female [53.6%]) were included in the analysis. The sample included 131 primary care practitioners (49.7%), 232 attending physicians (88.2%), and 168 academic faculty (63.9%). After 30 days with the ambient AI scribe, the proportion of participants experiencing burnout decreased significantly from 51.9% to 38.8% (odds ratio, 0.26; 95% CI, 0.13-0.54). On 10-point scales, the ambient AI scribe was associated with significant improvements in secondary outcomes of burnout (mean [SE] difference, 0.47 [0.12] points), note-related cognitive task load (mean [SE] difference, 2.64 [0.13] points), ability to provide undivided attention (mean [SE] difference, 2.05 [0.18] points), patient understandability of their care plans from reading the notes (mean [SE] difference, -0.44 [0.17] points), ability to add patients to the clinic schedule if urgently needed (mean [SE] difference, 0.51 [0.24] points), and time spent documenting after hours (mean [SE] difference, 0.90 [0.19] hours).

Conclusions and relevance: This multicenter quality improvement study found that use of an ambient AI scribe platform was associated with a significant reduction in burnout, cognitive task load, and time spent documenting, as well as the perception that it could improve patient access to care and increase attention on patient concerns in an ambulatory environment. These findings suggest that AI may help reduce administrative burdens for clinicians and allow more time for meaningful work and professional well-being.

Rationale: Respiratory syncytial virus (RSV) is a highly transmissible pathogen that causes varying degrees of respiratory illness across all age groups. The safety and efficacy profiles of available RSV vaccines, a critical consideration for their integration into public health strategies and clinical practice, remain uncertain.

Objectives: To assess the benefits and harms of RSV vaccines compared to placebo, no intervention, vaccines for other respiratory infections, other RSV vaccines, or monoclonal antibodies (mAbs) across all human populations.

Search methods: We conducted a comprehensive literature search of CENTRAL, MEDLINE, Embase, ClinicalTrials.gov, and the WHO ICTRP following standard systematic review methodology from 2000 to April 2024.

Eligibility criteria: We included both randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) involving all human populations comparing RSV vaccines with placebo, no intervention, vaccines for other respiratory infections, other RSV vaccines, or mAbs. We excluded studies focused on dose-finding schedules and immunogenicity assessment.

Outcomes: Benefits included frequency of RSV illness (both lower and upper respiratory illness) confirmed by laboratory tests (RSV-associated lower respiratory tract illness and RSV-associated acute respiratory illness); hospitalisation due to RSV disease (both lower and upper respiratory illness) confirmed by laboratory tests; mortality from illness caused by RSV (confirmed by laboratory test); all-cause mortality; and admission to an intensive care unit. Harms included serious adverse events (SAEs) related to vaccination, including neurological disorders such as Guillain-Barré syndrome.

Risk of bias: We assessed risk of bias in RCTs using Cochrane's RoB 2 tool.

Synthesis methods: We used standard Cochrane methods.

Included studies: We identified 14 RCTs: five trials (101,825 participants) on older adults; three trials (12,010 participants) on maternal vaccination and effects on infants; one trial (300 participants) on women of childbearing age; and five trials (192 participants) on infants and children. We identified no NRSIs.

Synthesis of results: RSV prefusion vaccine versus placebo in older adults These vaccines reduced RSV-associated lower respiratory tract illness with vaccine efficacy (VE) of 77% (95% confidence interval (CI) 0.70 to 0.83; risk ratio (RR) 0.23, 95% CI 0.17 to 0.30; 4 RCTs, 99,931 participants; high-certainty evidence) and RSV-associated acute respiratory illness with VE of 67% (95% CI 0.60 to 0.73; RR 0.33, 95% CI 0.27 to 0.40; 3 RCTs, 94,339 participants; high-certainty evidence). There may be little to no difference in mortality from illness caused by RSV, all-cause mortality, and SAEs related to vaccination (low-certainty evidence). RSV postfusion F protein-based vaccine versus placebo in older adults There is probably little to no difference in RSV-associated lower respiratory tract illness with VE of -0.37% (95% CI -1.96 to 0.37; RR 1.37, 95% CI 0.63 to 2.96; 1 RCT, 1894 participants; moderate-certainty evidence) and RSV-associated acute respiratory illness with VE of -0.07% (95% CI -1.15 to 0.47; RR 1.07, 95% CI 0.53 to 2.15; 1 RCT, 1894 participants; moderate-certainty evidence). There may be little to no difference in mortality from illness caused by RSV, all-cause mortality, and SAEs related to vaccination (low-certainty evidence). Maternal RSV F protein-based vaccine versus placebo in infants These vaccines reduced medically attended RSV-associated lower respiratory tract illness with VE of 54% (95% CI 0.28 to 0.71; RR 0.46, 95% CI 0.29 to 0.72; 3 RCTs, 12,010 participants; high-certainty evidence), medically attended RSV-associated severe lower respiratory tract illness with VE of 74% (95% CI 0.44 to 0.88; RR 0.26, 95% CI 0.12 to 0.56; 3 RCTs, 12,010 participants; high-certainty evidence), and hospitalisation due to RSV disease with VE of 54% (95% CI 0.27 to 0.71; RR 0.46, 95% CI 0.29 to 0.73; 2 RCTs, 11,502 participants; high-certainty evidence) in infants. There may be little to no difference in mortality from illness caused by RSV, all-cause mortality, and SAEs related to vaccination in mothers and infants (low-certainty evidence). Live-attenuated RSV vaccines versus placebo in infants and children The evidence is very uncertain regarding all-cause medically attended acute respiratory illness (MAARI) with VE of 26% (95% CI -0.01 to 0.46; RR 0.74, 95% CI 0.54 to 1.01; 5 RCTs, 171 participants; very low-certainty evidence) and RSV-associated MAARI with VE of 38% (95% CI -0.24 to 0.69; RR 0.62, 95% CI 0.31 to 1.24; 5 RCTs, 192 participants; very low-certainty evidence). There may be little to no difference in SAEs related to vaccination (low-certainty evidence). RSV recombinant F nanoparticle vaccine versus placebo in women of childbearing age The evidence is very uncertain regarding new RSV infections with VE of 50% (95% CI 0.08 to 0.73; RR 0.50, 95% CI 0.27 to 0.92; 1 RCT, 300 participants; very low-certainty evidence). There may be little to no difference in mortality from illness caused by RSV, all-cause mortality, and SAEs related to vaccination (low-certainty evidence). Phase III trials consistently demonstrated low risk of bias. Whilst phase I and II trials occasionally raised concerns about selection bias in the randomisation process, the overall evidence was deemed robust.

Authors' conclusions: RSV prefusion vaccines reduced RSV-associated lower respiratory tract illness and acute respiratory illness in older adults. There may be little to no difference in SAEs related to vaccination in older adults. Maternal vaccination with RSV F protein-based vaccines reduced medically attended RSV-associated lower respiratory tract illness and severe cases in infants. There may be little to no difference in SAEs related to vaccination in mothers and infants. The evidence is very uncertain regarding the effects of RSV vaccine on women of childbearing age, and the effects of live-attenuated RSV vaccines on infants and children; there may be little to no difference in SAEs related to vaccination.
