Changing landscape of medical conferences: identifying the goals motivating virtual vs in-person participation

Int J Med Educ. 2025 Jan 30;16:11-20. doi: 10.5116/ijme.676f.ce30.

ABSTRACT

OBJECTIVES: This study was aimed at improving clarity regarding the goals underlying motivation for attendance at international meetings to accommodate evolving needs.

METHODS: We performed a case study of a large international medical conference by undertaking (a) semi-structured interviews with 13 multi-disciplinary stakeholders, which underwent thematic analysis, and (b) surveys of 1229 conference attendees, which underwent descriptive statistical analysis and directed content analysis.

RESULTS: Interviews suggested scientific updates and networking are priorities for in-person formats whereas flexibility and reduced travel are priorities for virtual formats. Surveys suggested motivations for attending both in-person and virtual conferences included: scientific updates (81.3% and 85.4%, respectively) and advancements in patient care (76.6%, 78.2%). Social interaction (e.g., to meet experts 80.6% and make/deepen professional connections 69.3%) was highly rated for in-person meetings, but not virtual meetings (51.0% and 30.8%, respectively). 58.9% of attendees prefer future meetings to be hybrid, including both in-person and virtual formats.

CONCLUSIONS: We found a disconnect between attendees’ preferences and recommendations currently put forward as socially responsible in terms of climate, equity and diversity. Meeting organisers may need to educate others about the value and costs involved in hybrid formats. When hybrid formats are possible, our data provide guidance on what to prioritize during in-person components and how to combine those with the benefits of global accessibility and flexibility enabled by virtual technology.

Reconstructing Risk Dimensions in Telemedicine: Investigating Technology Adoption and Barriers During the COVID-19 Pandemic in Taiwan

J Med Internet Res. 2025 Feb 3;27:e53306. doi: 10.2196/53306.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has shifted health care toward virtual and online models, impacting both users and providers. Numerous user concerns and perceived risks related to telemedicine are continually evolving and adjusting in response to the pandemic. In many countries, there has been a substantial increase in the use of virtual health care visits, which offers a unique opportunity for researchers to explore these user concerns.

OBJECTIVE: This study aimed to first reconstruct the risk dimensions associated with telemedicine, then identify the risk factors affecting users’ adoption, and finally propose effective solutions to mitigate these concerns. By integrating the newly constructed perceived risk with the technology acceptance model (TAM), we scrutinized various dimensions of perceived risk and their influence on users’ perceptions of ease of use, perceived usefulness, and use intention (UI).

METHODS: Our target population consists of adults aged ≥18 years who have used or may use telemedicine services, recruited through an anonymous, voluntary, open, web-based survey. We collected responses and used part of them to reconstruct risk dimensions using exploratory factor analysis. Subsequently, we analyzed the intricate relationship between perceived risk, the TAM, and the acceptance of telemedicine using structural equation modeling with another part of the responses.

RESULTS: A total of 1600 valid responses were collected. Eight distinct risk dimensions were reconstructed, revealing a substantial negative impact of performance risk on UI. The psychological and social risk was the strongest barrier to the ease of using telemedicine. Time risk, provider risk, and privacy risk were not statistically significant to the TAM. The resulting model elucidates a remarkable 66% variance in UI for telemedicine services.

CONCLUSIONS: This study substantially advances the field of telemedicine research by reconstructing and redefining 8 risk dimensions and confirming the statistical significance of 5 perceived risks on the adoption of telemedicine services. These insights are poised to facilitate the promotion and enhancement of telemedicine services in the health care sector.

Colorectal Cancer Racial Equity Post Volume, Content, and Exposure: Observational Study Using Twitter Data

J Med Internet Res. 2025 Feb 3;27:e63864. doi: 10.2196/63864.

ABSTRACT

BACKGROUND: Racial inequity in health outcomes, particularly in colorectal cancer (CRC), remains one of the most pressing issues in cancer communication and public health. Social media platforms like Twitter (now X) provide opportunities to disseminate health equity information widely, yet little is known about the availability, content, and reach of racial health equity information related to CRC on these platforms. Addressing this gap is essential to leveraging social media for equitable health communication.

OBJECTIVE: This study aims to analyze the volume, content, and exposure of CRC racial health equity tweets from identified CRC equity disseminator accounts on Twitter. These accounts were defined as those actively sharing information related to racial equity in CRC outcomes. By examining the behavior and impact of these disseminators, this study provides insights into how health equity content is shared and received on social media.

METHODS: We identified accounts that posted CRC-related content on Twitter between 2019 and 2021. Accounts were classified as CRC equity disseminators (n=798) if they followed at least 2 CRC racial equity organization accounts. We analyzed the volume and content of racial equity-related CRC tweets (n=1134) from these accounts and categorized them by account type (experts vs nonexperts). Additionally, we evaluated exposure by analyzing follower reach (n=6,266,269) and the role of broker accounts-accounts serving as unique sources of CRC racial equity information to their followers.

RESULTS: Among 19,559 tweets posted by 798 CRC equity disseminators, only 5.8% (n=1134) mentioned racially and ethnically minoritized groups. Most of these tweets (641/1134, 57%) addressed disparities in outcomes, while fewer emphasized actionable content, such as symptoms (11/1134, 1%) or screening procedures (159/1134, 14%). Expert accounts (n=479; 716 tweets) were more likely to post CRC equity tweets compared with nonexpert accounts (n=319; 418 tweets). Broker accounts (n=500), or those with a substantial portion of followers relying on them for equity-related information, demonstrated the highest capacity for exposing followers to CRC equity content, thereby extending the reach of these critical messages to underserved communities.

CONCLUSIONS: This study emphasizes the critical roles played by expert and broker accounts in disseminating CRC racial equity information on social media. Despite the limited volume of equity-focused content, broker accounts were crucial in reaching otherwise unexposed audiences. Public health practitioners should focus on encouraging equity disseminators to share more actionable information, such as symptoms and screening benefits, and implement measures to amplify the reach of such content on social media. Strengthening these efforts could help bridge disparities in cancer outcomes among racially minoritized groups.

Effectiveness of Electronic Quality Improvement Activities to Reduce Cardiovascular Disease Risk in People With Chronic Kidney Disease in General Practice: Cluster Randomized Trial With Active Control

JMIR Form Res. 2025 Feb 3;9:e54147. doi: 10.2196/54147.

ABSTRACT

BACKGROUND: Future Health Today (FHT) is a program integrated with electronic medical record (EMR) systems in general practice and comprises (1) a practice dashboard to identify people at risk of, or with, chronic disease who may benefit from intervention; (2) active clinical decision support (CDS) at the point of care; and (3) quality improvement activities. One module within FHT aims to facilitate cardiovascular disease (CVD) risk reduction in people with chronic kidney disease (CKD) through the recommendation of angiotensin-converting enzyme inhibitor inhibitors (ACEI), angiotensin receptor blockers (ARB), or statins according to Australian guidelines (defined as appropriate pharmacological therapy).

OBJECTIVE: This study aimed to determine if the FHT program increases the proportion of general practice patients with CKD receiving appropriate pharmacological therapy (statins alone, ACEI or ARB alone, or both) to reduce CVD risk at 12 months postrandomization compared with active control (primary outcome).

METHODS: General practices recruited through practice-based research networks in Victoria and Tasmania were randomly allocated 1:1 to the FHT CKD module or active control. The intervention was delivered to practices between October 4, 2021, and September 30, 2022. Data extracted from EMRs for eligible patients identified at baseline were used to evaluate the trial outcomes at the completion of the intervention period. The primary analysis used an intention-to-treat approach. The intervention effect for the primary outcome was estimated with a marginal logistic model using generalized estimating equations with robust SE.

RESULTS: Overall, of the 734 eligible patients from 19 intervention practices and 715 from 21 control practices, 82 (11.2%) and 70 (9.8%), respectively, had received appropriate pharmacological therapy (statins alone, ACEI or ARB alone, or both) at 12 months postintervention to reduce CVD risk, with an estimated between-trial group difference (Diff) of 2.0% (95% CI -1.6% to 5.7%) and odds ratio of 1.24 (95% CI 0.85 to 1.81; P=.26). Of the 470 intervention patients and 425 control patients that received a recommendation for statins, 61 (13%) and 38 (9%) were prescribed statins at follow-up (Diff 4.3%, 95% CI 0 to 8.6%; odds ratio 1.55, 95% CI 1.02 to 2.35; P=.04). There was no statistical evidence to support between-group differences in other secondary outcomes and general practice health care use.

CONCLUSIONS: FHT harnesses the data stored within EMRs to translate guidelines into practice through quality improvement activities and active clinical decision support. In this instance, it did not result in a difference in prescribing or clinical outcomes except for small changes in statin prescribing. This may relate to COVID-19-related disruptions, technical implementation challenges, and recruiting higher performing practices to the trial. A separate process evaluation will further explore factors impacting implementation and engagement with FHT.

Assessing the Relationship Between Mandibular Contouring and Iatrogenic Jowling in Facial Feminization Surgery

J Craniofac Surg. 2025 Feb 3. doi: 10.1097/SCS.0000000000011132. Online ahead of print.

ABSTRACT

Lower-third facial feminization procedures have been associated with the development of postoperative jowling, yet quantitative evaluations of this outcome remain limited. This study evaluated the relationship between patient risk factors and bony volume reduction with postoperative jowling. Chin and gonial angle bony measurements were obtained from preoperative and postoperative computed tomography imaging, whereas changes in jowling were assessed using a validated photonumeric jowling scale on preoperative and postoperative patient images. Associations between skeletal changes, demographic variables, and soft tissue outcomes were statistically analyzed. The study included 35 patients with a mean age of 36 ± 12 years. The average time between surgery and postoperative photographs was 10.0 ± 7.5 months. Gonial angle volume decreased by 9.48% (P < 0.001), whereas chin volume decreased by 3.06% (P = 0.051). Average jowling grade increased significantly from 2.3 to 2.6 postoperatively (P = 0.03), with higher age correlating to a greater increase in jowling (r = 0.35, P = 0.037). Postoperatively, only body mass index was significantly correlated with absolute jowling score (r = 0.51, P = 0.0018). However, no significant associations were found between changes in bony measurements and changes in jowling scores. These findings underscore the importance of further investigating the interplay between patient risk factors and bony and soft tissue changes in facial feminization surgery. Future studies will focus on expanded cohorts and more sensitive assessment tools to better define risk factors and optimize surgical strategies for minimizing jowling.

Pathogenesis of Ectopic Inner Foveal Layers (EIFL) and Its Impact on Visual Recovery after Epiretinal Membrane Peeling

Retina. 2025 Jan 29. doi: 10.1097/IAE.0000000000004418. Online ahead of print.

ABSTRACT

PURPOSE: To determine the pathoanatomical alteration of ectopic inner foveal layers (EIFL) and its relationship to visual recovery after epiretinal membrane (ERM) peeling surgery.

METHODS: Clinical charts and tracked spectral-domain optical coherence tomography images of patients diagnosed with stage 3 and 4 ERM were reviewed and analyzed preoperatively and at 3 and 6 months postoperatively. Central macular thickness (CMT) and EIFL thickness were measured at these time points. Wilcoxon signed-rank test was used for analysis and P < 0.05 was considered statistically significant.

RESULTS: The study cohort consisted of 54 eyes of 54 patients, 27 of whom were female. The mean age was 69.2 years. The mean Snellen VA improved from 20/50 preoperatively to 20/35 at 3 months (P<0.001) and remained 20/35 at 6 months, significantly better than preoperative levels (P=0.002). The mean preoperative EIFL thickness was 169.15 µm and decreased to 95.70 µm at 3 months (P = 0.001) and 90.95 µm at 6 months (P = 0.02). Similarly, CMT reduced from 510.00 µm preoperatively to 444.56 µm at 3 months (P < 0.001) and 415.50 µm at 6 months (P < 0.001). Reduction in EIFL thickness was significantly correlated with improvement in log-MAR VA (P =0.02) 6 months after surgery.

CONCLUSION: ERM peeling results in reduced EIFL thickness, restoration of the normal foveal pit structure, and a corresponding improvement in visual acuity. Reduction in EIFL thickness is correlated with visual improvement.

Statistical Practice of Ordinal Outcome Analysis in Neurologic Trials: A Literature Review

Neurology. 2025 Feb 25;104(4):e210229. doi: 10.1212/WNL.0000000000210229. Epub 2025 Feb 3.

ABSTRACT

BACKGROUND AND OBJECTIVES: Ordinal scales are widely adopted as outcome measures in neurologic randomized controlled trials (RCTs). We aimed to evaluate which statistical methods have been used to test and estimate treatment effects from ordinal outcomes in recent RCTs across a range of acute neurologic diseases.

METHODS: We searched PubMed for RCTs in 5 acute monophasic neurologic diseases (stroke, traumatic brain injury [TBI], subarachnoid hemorrhage [SAH], meningitis, and Guillain-Barré syndrome [GBS]) published in high-impact journals between January 1, 2015, and November 1, 2023. Trials had to report on an ordinal scale as the primary or secondary efficacy outcome. Two independent reviewers performed study screening and data extraction. We evaluated the results to determine how investigators (1) addressed the ordinal nature of outcomes, (2) assessed and reported key assumptions, (3) used longitudinal measurements, and (4) adjusted for prognostic covariates.

RESULTS: We reviewed 70 RCTs for treatment evaluations in stroke (n = 36), TBI (n = 13), SAH (n = 10), meningitis (n = 7), and GBS (n = 4). In 46 of 70 trials (66%), investigators retained the full ordering information, commonly analyzed using a proportional odds model (33/46 trials, 72%). The proportional odds assumption was not addressed in 23 of 33 trials (62%). In 22 of 70 trials (31%), the ordinal outcome was dichotomized, with notable variation in the cut-point for each ordinal scale. In 41 of 70 trials (59%), the ordinal outcome was assessed at multiple time points while some form of longitudinal data analysis was performed in only 3 of these 41 studies (7%). The time point chosen for analysis varied within neurologic conditions. Covariate adjustment was reported in 48 of 70 studies (69%).

DISCUSSION: There is a large variation in the current practice of analyzing ordinal outcomes in neurologic trials. Dichotomization and focus on a single time point are common; therefore, information contained in the rank ordering of the outcome and repeated measurements is not fully used. Further research needs to clarify the balance between maximizing the statistical power, making assumptions, and allowing for straightforward interpretations in approaches that make more effective use of the outcome data.

Increases In Physician Professional Fees In Private Equity-Owned Gastroenterology Practices

Health Aff (Millwood). 2025 Feb;44(2):215-223. doi: 10.1377/hlthaff.2024.00190.

ABSTRACT

Consolidation of physician practices, largely driven by health systems, has motivated policy efforts to move care toward lower-price, non-health system settings. At the same time, however, private equity (PE) firms are increasingly acquiring those non-health system practices, potentially negating the prior price advantages of those practices. We used novel ownership data on gastroenterology practices linked to commercial claims for the period 2015-20 to study how PE acquisitions affect the prices and volume of care relative to both health system-affiliated practices and independent practices. We examined both professional fees and facility fees. After PE acquisition, prices increased by $92 per claim, or 28.4 percent, driven by a 78.1 percent increase in professional fees. Facility fees did not exhibit a statistically significant change. Meanwhile, utilization also increased. These findings suggest that PE firms have multiple avenues for raising prices-in this case, primarily via professional fees. For policy makers, although moving care out of higher-price health system settings remains a key strategy to lower spending, unchecked growth in professional fees in PE-acquired outpatient settings may nullify some of the intended effects.

Abortion Rate Increased And Birth Rate Decreased After Introduction Of Medicaid Abortion Coverage In Illinois

Health Aff (Millwood). 2025 Feb;44(2):224-233. doi: 10.1377/hlthaff.2024.00145.

ABSTRACT

The Hyde Amendment prohibits US federal spending on abortion, including federal Medicaid dollars. Seventeen states cover abortion care in their Medicaid programs, using state funds, but causal evidence on how Medicaid coverage for abortion affects pregnancy outcomes is limited. Using a difference-in-differences design and 2014-21 birth and abortion data from the Centers for Disease Control and Prevention that predate the US Supreme Court’s Dobbs decision in 2022, we evaluated a 2018 policy introducing Medicaid coverage for abortion in Illinois. This change increased the number of abortions in the state by 2.43 per 1,000 reproductive-age females, an 18.2 percent increase, and reduced births by 1.66 per 1,000 reproductive-age females, a 2.8 percent decrease, relative to twenty-nine comparison states that did not cover abortion during the study period. Subgroup analyses of birth rates suggested that decreases in birth rates were more pronounced among Black and Hispanic residents, residents in counties with higher poverty rates, and residents closer to an abortion facility. Our finding suggests that Medicaid can play an important role in abortion access.

The Number Of Family Caregivers Helping Older US Adults Increased From 18 Million To 24 Million, 2011-22

Health Aff (Millwood). 2025 Feb;44(2):187-195. doi: 10.1377/hlthaff.2024.00978.

ABSTRACT

The evolving composition and experiences of the family caregiver workforce have profound ramifications for public policy but are not well understood. Drawing on the linked National Health and Aging Trends Study and National Study of Caregiving, we found that the numbers of family caregivers providing help to older adults increased by nearly six million between 2011 and 2022, rising from 18.2 million to 24.1 million. Among older adults receiving care, network size was stable, at about two caregivers per older adult at both points in time. However, in 2022, family caregivers were assisting older adults who were younger, more likely to be male and better educated, and less likely to have dementia. We found few changes in competing work and child care responsibilities, weekly care hours, and caregiving-related difficulty. A smaller number of family caregivers were assisting fewer older adults with dementia, but in this group, co-residence increased by 25 percent, average care hours increased by 50 percent, and employment decreased. For family caregivers as a whole, challenges persist, and for those assisting people with dementia, tailored surveillance and effective support programs are needed.
