Abstract Background Clinical laboratories receive frequent inbound phone calls from healthcare providers related to test ordering, specimen status, and result availability. In high-volume clinical laboratory environments, limited phone triage specificity may result in high call volumes reaching laboratory staff that could be addressed through alternative routing or standardized messaging. This project evaluated provider phone call volume and call type distribution within a high-volume centralized clinical laboratory call center and assessed the impact of targeted redesign of phone triage options. Methods Inbound provider phone calls answered by staff in a centralized clinical laboratory call center were prospectively tracked using standardized tally sheets. Calls were categorized into four predefined call types: requests for transfer to another area or operator misdirects, questions regarding tests not performed in the central clinical laboratory, requests for patient results or confirmation of specimen receipt, and questions regarding test add-on eligibility or specimen availability. Pre-intervention phone triage consisted of a limited 2 option call routing menu routing calls bidirectionally for patient result inquiries versus all other laboratory questions. Based on pre-intervention call category data, a revised phone menu was implemented that included a standardized message instructing callers to allow two hours from specimen collection prior to results inquiries, followed by three targeted menu options for patient result inquiries, add-on or specimen availability questions, or direct connection to Central Processing staff. Operator routing logic was concurrently refined by reducing keyword triggers associated with incorrect transfers. Three study periods were evaluated: pre-intervention, post-intervention, and four months post-intervention. Daily call volume and average+/-standard deviation (SD) percent and type of calls directed to call center staff were measured. Results A total of 57 operational days were analyzed, including 25 pre-intervention days, 18 post-intervention days, and 14 days at four months post-intervention, representing 8,352 total inbound provider phone calls. Across all study periods, average (+/-SD) daily call volume was 147+/-42 calls. During the pre-intervention period (n=3,596 total calls), 24.1+/-9.8% of calls received per day met the criteria for the four predefined categories. During the post-intervention period (n=2,905 calls) and the four months post-intervention period (n= 1,851 calls), 8.4+/-5.6% and 15.6+/-7.9 % of calls received met the same criteria. In the pre-intervention period (n=3,596 calls), calls categorized as requests for transfer or operator misdirect, questions about testing for non-central clinical laboratory tests, calls requesting results or confirmation of specimen receipt, and questions regarding test add-on eligibility or specimen availability were 8.3%, 10.0%, 10.6%, and 8.2%, respectively. Corresponding category percentages during the post-intervention period (n=2905 calls) were 1.8%, 5.1%, 4.2%, and 4.3%, and at four months post-intervention (n=1851 calls) were 3.5%, 8.8%, 6.3%, and 4.9%, respectively. Conclusion Systematic measurement of provider phone call volume and call type distribution in a high-volume clinical laboratory call center enabled targeted redesign of phone triage options, including menu restructuring, standardized messaging, and refinement of operator routing logic. The volume of calls routed to call center staff was significantly reduced after redesigning the phone triage options and improvement was sustained four months post-intervention.

Traditional home-call managing after-hours pager communications remains a common component of hematology-oncology fellowship and modern practice. Little is known about these patient-related interactions and implications. This project aimed to characterize after-hours pager volumes and evaluate perceived impacts on care, physician wellbeing, and trainee education. We performed a mixed-methods study at a tertiary academic center, analyzing after-hours pager activity from 2020-2024 across Hematology Consult (HCP), Hematology Outpatient (HOP), and Medical Oncology (MOP) pagers. A survey of hematology-oncology fellows evaluated perceptions and attitudes toward the home-call experience using free-text responses and a 5-point Likert scale. After-hours pager burden was substantial and sustained. The MOP received >3,000 pages annually, with medians of 5-6 per weekday and 15-15.5 per weekend day. The HOP volume nearly doubled over the study period (960 to 1,721 annually) with median pager volumes of 1-3 per weekday and 2-7 per weekend day. The HCP volume ranged from 594-768 pages annually. Survey response rate was 58% (19/33). Only 16% of fellows endorsed educational value from patient calls on MOP or HOP, and ≤5% agreed that call tasks required physician-level expertise. Respondents reported that the pager resulted in fatigue, anxiety, and social disruptions. Free text responses revealed themes of low educational value, high non-urgent call volume, and system inefficiencies. Contemporary home-call had substantial pager burdens with limited actionability, adverse effects on wellbeing, and low educational value. Systems engineering, including triage processes and augmented patient education, could help optimize patient care, physician wellbeing, and trainee education.

Background: Perinatal and early-life factors may influence non-Hodgkin lymphoma (NHL) risk, but study results have been mixed and exposure data for childhood ages are limited. Herein, we investigated associations of these exposures with risk of NHL and common subtypes. Methods: This case–control study included 2280 NHL cases and 2253 controls, enrolled from 2002 to 2014 at the Mayo Clinic Rochester. Self-reported perinatal and early-life exposures included maternal age at birth, birth order, birthweight, time breastfed, height and weight at ages 7, 12, and 18 years relative to peers, and age and weight when growth ceased. We used logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs), adjusting for design variables and potential confounders. Linear trend tests were performed for ordinal variables, and heterogeneity tests were performed to evaluate whether associations varied across four NHL subtypes. Results: After multivariable adjustment, greater birth weight (OR = 1.15 for quartile 4 vs. 1; p-trend = 0.04), weight at age 7 relative to peers (compared to average, OR = 1.05 for heavy and OR = 0.87 for thin; p-trend = 0.002), and weight when growth ceased (OR = 1.30 for quartile 4 vs. 1; p-trend < 0.001) were associated with increased NHL risk. An inverse association was observed for breastfeeding duration with NHL risk (OR = 0.77 for >6 months vs. never; 95% CI 0.61–0.97). Associations did not significantly vary by major NHL subtype (p-heterogeneity > 0.05). Other perinatal and early-life exposures were not associated with NHL risk. Conclusions: Greater body weight at birth and through childhood may be associated with increased NHL risk, potentially extending the life-course perspective on adiposity and lymphomagenesis, with implications for prevention.

Abstract Patients with atypical variants of Alzheimer's disease (AD) often present at a younger age with predominantly non‐amnestic impairments and a more aggressive disease course. Historically, individuals with atypical presentations have not been included in large‐scale clinical trials, which typically focus on late‐onset, sporadic amnestic‐predominant AD. Consequently, treatment options and research efforts specific to atypical AD remain limited. The emergence of amyloid‐targeting therapies that slow disease progression underscores these challenges, as evidence supporting their efficacy in early‐onset amnestic and non‐amnestic AD variants is scarce. This perspective article argues that atypical AD represents an excellent disease model for clinical trials and proposes strategies to address critical gaps in clinical trial design for this population. Key considerations include optimizing participant selection approaches, establishing syndrome‐specific or surrogate biological and clinical endpoints, and fostering advocacy to enhance early and accurate diagnosis, equitable representation, and outcomes for these populations.

e23211 Background: The Syrian conflict, ongoing since 2011, has significantly disrupted healthcare delivery, particularly in oncology. With the destruction of many regional cancer centers, access to care has become centralized in Damascus, home to Al Bairouni University Hospital—the nation’s primary cancer referral facility. This study examines the geographic distribution and stage at diagnosis of prostate cancer patients, highlighting post-conflict disparities in access and outcomes. Methods: We conducted a retrospective chart review of all prostate cancer patients diagnosed at Al Bairouni University Hospital between January 2022 and December 2024. Data on age, residency, and stage at diagnosis were extracted and analyzed descriptively. Results: A total of 859 patients were included, with a mean age of 69 years (SD 9). Only 47% (n = 405) of patients resided in Damascus or its suburbs (Rif-Dimashq), while the majority (53%, n = 462) traveled from other governorates—most notably Aleppo (8.5%), Hama (9.1%), Homs (8.4%), and Al-Hasakah (6.2%). This geographic pattern reflects the collapse of regional oncology services due to prolonged conflict.Alarmingly, 65% of patients (n = 507) were diagnosed with metastatic disease (stage IV), while only 16% and 19% presented with localized and regional stages, respectively. This contrasts sharply with global trends and suggests systemic gaps in early detection. Contributing factors may include the absence of structured screening programs, weak insurance system and primary care infrastructure, low prostate cancer awareness, fear of cancer diagnosis, financial barriers, and limited healthcare access in rural areas. Conclusions: This study reveals the deep, lingering effects of war on prostate cancer care in Syria. The centralization of oncology services places undue burden on patients traveling long distances for care, while the predominance of advanced-stage diagnoses underscores the need for robust early detection efforts. These findings support urgent investment in rebuilding regional cancer infrastructure, expanding community-based health services, and improving access to timely diagnosis and treatment as the country enters a phase of reconstruction.

Abstract Background Ventilated patients in the intensive care unit are often complex and require multiple care team members including bedside nurses, respiratory therapists, advanced practice providers, and physicians. A Quality Improvement initiative was created to address any barriers in communication. Spontaneous breathing trials (SBT) are often used as a surrogate for multidisciplinary communication. Both Respiratory therapist (RT) and provider led spontaneous breathing trial protocols are often performed but not necessarily documented or communicated appropriately. Our primary aim was to increase spontaneous breathing trial documentation from a baseline of 12% to 80% with a counterbalance of not increasing the 24-hour reintubation rate. Methods Using the DMAIC framework, we defined the gap in quality by getting baseline patient data for 3 months including SBT completion rate, SBT documentation rate, time to first SBT, total time on ventilator, 24-hour reintubation rate, and total ICU days. All care team members including providers, RTs, and nurses completed a 10-questions Likert 5-scale survey regarding their views of multidisciplinary communication and SBT completion. We identified the lack of documentation of SBTs and implemented a standardized respiratory therapy shift summary note which included SBT details and major ventilator changes. We then collected the same data over 3 months after implementation. Results Post intervention analysis revealed documentation of daily spontaneous breathing trials improved from 12% to 79%. Pre and post intervention means for patient focused outcomes were statistically unchanged for time to first SBT 26 hours vs 32 hours (p = 0.16), Total ventilator time 5.6 vs 5.4 (p = 0.83), total ICU days 1.9 days vs 2.7 days (p = 0.11), and reintubation rate 14% vs 15%.Survey results showed that there was a statistically significant improvement in overall satisfaction regarding multidisciplinary communication, satisfaction regarding ventilator management discussion on rounds, and if documentation amount was appropriate. Also, there was a significant improvement in the percentage of care team members that were aware of daily SBTs occurring. Conclusion The implementation of RT shift summary greatly improved staff member satisfaction, multidisciplinary discussion during rounds, and awareness of SBT occurrence among providers, RTs, and nurses. While patient centered outcomes were statistically unchanged over this very brief period of observation, having better staff satisfaction and communication may eventually lead to improved outcomes over time and can lead to further analysis to avoid mishaps that can arise from miscommunication.
