RESUMO

Background: Novel applications of telemedicine can improve care quality and patient outcomes. Telemedicine for intraoperative decision support has not been rigorously studied. Methods: This single centre randomised clinical trial ( clinicaltrials.gov NCT03923699 ) of unselected adult surgical patients was conducted between July 1, 2019 and January 31, 2023. Patients received usual care or decision support from a telemedicine service, the Anesthesiology Control Tower (ACT). The ACT provided real-time recommendations to intraoperative anaesthesia clinicians based on case reviews, machine-learning forecasting, and physiologic alerts. ORs were randomised 1:1. Co-primary outcomes of 30-day all-cause mortality, respiratory failure, acute kidney injury (AKI), and delirium were analysed as intention-to-treat. Results: The trial completed planned enrolment with 71927 surgeries (35956 ACT; 35971 usual care). After multiple testing correction, there was no significant effect of the ACT vs. usual care on 30-day mortality [641/35956 (1.8%) vs 638/35971 (1.8%), risk difference 0.0% (95% CI -0.2% to 0.3%), p=0.96], respiratory failure [1089/34613 (3.1%) vs 1112/34619 (3.2%), risk difference -0.1% (95% CI -0.4% to 0.3%), p=0.96], AKI [2357/33897 (7%) vs 2391/33795 (7.1%), risk difference -0.1% (-0.6% to 0.4%), p=0.96], or delirium [1283/3928 (32.7%) vs 1279/3989 (32.1%), risk difference 0.6% (-2.0% to 3.2%), p=0.96]. There were no significant differences in secondary outcomes or in sensitivity analyses. Conclusions: In this large RCT of a novel application of telemedicine-based remote monitoring and decision support using real-time alerts and case reviews, we found no significant differences in postoperative outcomes. Large-scale intraoperative telemedicine is feasible, and we suggest future avenues where it may be impactful.

RESUMO

Sickle cell disease (SCD) is well recognized as a hypercoagulablestate, however, it remains unclear whether a subgroup of children with SCD at higher risk of venous thromboembolic event (VTE) during hospitalization may benefit from thromboprophylaxis. Our objectives were to describe the clinical characteristics, outcomes and recurrence of hospital acquired VTE in patients with SCD younger than 21 years. This was a single center retrospective study. Data regarding demographics, reason for admission, location of VTE, risk factors like central venous catheter (CVC), intensive care unit (ICU) admission among others were extracted from electronic medical records over a 10-year study period (2011-2021). Recurrence of VTE at 1 and 5 years was assessed. Descriptive statistics were used as indicated. We identified a total of 20 VTE events over the 10-year study period. Six of these events occurred in those younger than 12 years of age. Fourteen (70%) VTE events occurred in the HbSS or HbSßThal0 genotypes compared to 6 (30%) in HbSC. Most common VTE was isolated pulmonary embolism (PE) (n = 10, 50%). VTE were most often associated with acute chest syndrome (ACS) (n = 14, 70%), ICU admissions (n = 10, 50%) and CVC (n = 5/9, 55%). One patient died from the VTE event. One patient with additional underlying risk factors had a recurrent VTE at 13 months. Our study suggests that ICU admission, ACS and presence of CVC increases the risk of VTE in children and young adults with SCD, but larger studies are indicated to validate our findings.

RESUMO

This study compared borderline personality disorder (BPD) and bipolar 2 disorder (BP 2 disorder) with respect to reported childhood trauma and Five-Factor personality traits using the Childhood Trauma Questionnaire (CTQ) and the NEO Five-Factor Inventory (NEO-FFI). Participants were 50 men and women, aged 18-45, with DSM-5-diagnosed BPD and 50 men and women in the same age group with DSM-5-diagnosed BP 2 disorder. Participants could not meet criteria for both BPD and BP 2 disorder. Borderline participants had significantly higher scores on the neuroticism subscale and significantly lower scores on the agreeableness subscale of the NEO-FFI. After correction for multiple comparisons, there were no between-group differences on CTQ scores. Study results suggest that BPD and BP 2 disorder differ primarily with respect to underlying temperament/genetic architecture and that environmental factors have only a limited role in the differential etiologies of the two disorders.

RESUMO

Renal cell carcinoma (RCC) bone metastatis progression is driven by crosstalk between tumor cells and the bone microenvironment, which includes osteoblasts, osteoclasts, and osteocytes. RCC bone metastases (RCCBM) are predominantly osteolytic and resistant to antiresorptive therapy. The molecular mechanisms underlying pathologic osteolysis and disruption of bone homeostasis remain incompletely understood. We previously reported that BIGH3/TGFBI (transforming growth factor-beta-induced protein ig-h3, shortened to BIGH3 henceforth) secreted by colonizing RCC cells drives osteolysis by inhibiting osteoblast differentiation, impairing healing of osteolytic lesions, which is reversible with osteoanabolic agents. Here, we report that BIGH3 induces osteocyte apoptosis in both human RCCBM tissue specimens and in a preclinical mouse model. We also demonstrate that BIGH3 reduces Cx43 expression, blocking gap junction (GJ) function and osteocyte network communication. BIGH3-mediated GJ inhibition is blocked by the lysosomal inhibitor hydroxychloroquine (HCQ), but not osteoanabolic agents. Our results broaden the understanding of pathologic osteolysis in RCCBM and indicate that targeting the BIGH3 mechanism could be a combinational strategy for the treatment of RCCBM-induced bone disease that overcomes the limited efficacy of antiresorptives that target osteoclasts.

RESUMO

Introduction: During the COVID-19 pandemic, our institution adopted telemedicine for voice therapy (VT) as an alternative to in-person sessions, which has been integrated into our routine practice following the pandemic. This study aims to explore factors influencing completion rates among the 2 methods. Method: A retrospective chart review at a single tertiary care institution between 2019 and 2021 was conducted. Patient zip codes were used to determine Neighborhood Atlas® Area Deprivation Index (ADI) scores and travel distance to our institution. Demographic data, Voice Handicap Index (VHI) scores, and completion status were extracted. Results: Between 2019 and 2021, 521 patients were referred to VT at our institution, with 29% opting for telemedicine VT (TVT) sessions and 71% choosing in-person sessions. Seventy-four percent was female, and average age was 57.1 years (range:10-89 years old). No statistically significant differences were observed between the 2 groups regarding sex, age, employment status, or insurance type. Participants in the TVT group demonstrated notably higher completion rates compared to the in-person group [70.0% vs 31.6% (P < .001)]. The TVT group also comprised of a higher percentage of white patients, reported longer travel distances and times to reach therapy, but had comparable ADI scores to the in-person group. Moreover, there were no significant differences in pretreatment VHI scores between the 2 groups or between those who completed therapy versus those who did not (P = .501). Conclusion: Our findings indicate that patients utilizing the telemedicine platform had significantly higher VT completion rates compared to patients appearing in person. These results highlight the importance of being able to offer telemedicine-based options in the management of voice patients.

RESUMO

BACKGROUND: The physical and psychological benefits of physical activity are well-known, and physical activity has been proven to be a helpful adjunct to psychotherapeutic treatment for many symptomatic disorders, including mood and anxiety disorders. The current study explores physical inactivity levels in patients with borderline personality disorder (BPD). The first aim of this study is to describe the 12-year course of physical inactivity in patients with BPD. The second aim is to examine predictors of physical inactivity, including adversity experiences, comorbid symptomatic (formerly axis I) disorders, medical disorders, and demographic factors. METHODS: Two hundred and forty-five patients with BPD were interviewed seven times over 12-years of prospective follow-up as part of the McLean Study of Adult Development (MSAD). Patients were categorized as ever-recovered (i.e., patient had experienced a symptomatic and psychosocial recovery from BPD) or never-recovered. At each follow-up, patients reported physical activity levels (minutes of exercise per week) via a semi-structured interview- the Medical History and Services Utilization Interview (MHSUI). Data was collected from June 1992 to December 2018. RESULTS: Never-recovered patients with BPD were significantly more inactive than their ever-recovered counterparts (p < 0.001). These rates of inactivity remained stable over time for both groups. Two significant multivariate predictors of inactivity were found: obesity (p = 0.003) and PTSD (p < 0.001). CONCLUSIONS: Non-recovered BPD patients are more likely to be inactive than patients who have recovered. Both clinical and medical factors appear to contribute to inactivity levels in patients with BPD.

RESUMO

Oncogenic mutations in KRAS are present in approximately 95% of patients diagnosed with pancreatic ductal adenocarcinoma (PDAC) and are considered the initiating event of pancreatic intraepithelial neoplasia (PanIN) precursor lesions. While it is well established that KRAS mutations drive the activation of oncogenic kinase cascades during pancreatic oncogenesis, the effects of oncogenic KRAS signaling on regulation of phosphatases during this process is not fully appreciated. Protein Phosphatase 2A (PP2A) has been implicated in suppressing KRAS-driven cellular transformation. However, low PP2A activity is observed in PDAC cells compared to non-transformed cells, suggesting that suppression of PP2A activity is an important step in the overall development of PDAC. In the current study, we demonstrate that KRASG12D induces the expression of both an endogenous inhibitor of PP2A activity, Cancerous Inhibitor of PP2A (CIP2A), and the PP2A substrate, c-MYC. Consistent with these findings, KRASG12D sequestered the specific PP2A subunit responsible for c-MYC degradation, B56α, away from the active PP2A holoenzyme in a CIP2A-dependent manner. During PDAC initiation in vivo, knockout of B56α promoted KRASG12D tumorigenesis by accelerating acinar-to-ductal metaplasia (ADM) and the formation of PanIN lesions. The process of ADM was attenuated ex vivo in response to pharmacological re-activation of PP2A utilizing direct small molecule activators of PP2A (SMAPs). Together, our results suggest that suppression of PP2A-B56α through KRAS signaling can promote the MYC-driven initiation of pancreatic tumorigenesis.

RESUMO

BACKGROUND: Patients often desire involvement in anesthesia decisions, yet clinicians rarely explain anesthesia options or elicit preferences. We developed My Anesthesia Choice-Hip Fracture, a conversation aid about anesthesia options for hip fracture surgery and tested its preliminary efficacy and acceptability. METHODS: We developed a 1-page, tabular format, plain-language conversation aid with feedback from anesthesiologists, decision scientists, and community advisors. We conducted an online survey of English-speaking adults aged 50 and older. Participants imagined choosing between spinal and general anesthesia for hip fracture surgery. Before and after viewing the aid, participants answered a series of questions regarding key outcomes, including decisional conflict, knowledge about anesthesia options, and acceptability of the aid. RESULTS: Of 364/409 valid respondents, mean age was 64 (SD 8.9) and 59% were female. The proportion indicating decisional conflict decreased after reviewing the aid (63-34%, P < 0.001). Median knowledge scores increased from 50% correct to 67% correct (P < 0.001). 83% agreed that the aid would help them discuss options and preferences. 76.4% would approve of doctors using it. CONCLUSION: My Anesthesia Choice-Hip Fracture decreased decisional conflict and increased knowledge about anesthesia choices for hip fracture surgery. Respondents assessed it as acceptable for use in clinical settings. PRACTICE IMPLICATIONS: Use of clinical decision aids may increase shared decision-making; further testing is warranted.

RESUMO

PURPOSE: While limited resources can make high-quality, comprehensive, coordinated cancer care provision challenging in rural settings, rural cancer patients often rely on local hospitals for care. To develop resources and strategies to support high-quality local cancer care, it is critical to understand the current experiences of rural cancer care physicians, including perceived strengths and challenges of providing cancer care in rural areas.  METHODS: Semi-structured interviews were conducted with 13 cancer providers associated with all 12 non-metropolitan/rural Iowa hospitals that diagnose or treat >100 cancer patients annually. Iterative thematic analysis was conducted to develop domains. FINDINGS: Participants identified geographic proximity and sense of community as strengths of local care. They described decision-making processes and challenges related to referring patients to larger centers for complex procedures, including a lack of dedicated navigators to facilitate and track transfers between institutions and occasional lack of respect from academic physicians. Participants reported a desire for strengthening collaborations with larger urban/academic cancer centers, including access to educational opportunities, shared resources and strategies to collect and monitor data on quality, and clinical trials. CONCLUSIONS: Rural cancer care providers are dedicated to providing high-quality care close to home for their patients and would welcome opportunities to increase collaboration with larger centers to improve coordination and comprehensiveness of care, collect and monitor data on quality of care, and access continuing education opportunities. Further research is needed to develop implementation approaches that will extend resources, services, and expertise to rural providers to facilitate high-quality cancer care for all cancer patients.

RESUMO

Background: Pediatric cardiac patients have experienced evolving illnesses progressing to instability while awaiting inpatient admission from ambulatory settings. Admission delays and communication breakdowns increase the risk for tenuous patients. This quality improvement initiative aimed to improve safety and efficiency for patients admitted from an ambulatory Clinic to the Acute Cardiac Care Unit (ACCU) using standardized communication and admission processes within one year. Methods: An admission process map, in-clinic nurse monitoring, and communication pathways were developed and implemented. A standardized team handoff occurred via virtual huddle using illness severity, patient summary, action list, situational awareness, and synthesis. Escalation of care events and timeliness were compared pre- and postimplementation. Results: There was a reduction of transfers to the intensive care unit within 24 hours of ACCU admission from 9.2% to 3.8% (P = 0.26), intensive care unit evaluations (without transfer) from 5.6% to 0% (P = 0.06), and arrests from 3.7% to 0% (P = 0.16). After the pilot, clinic nurses monitored 100% of at-risk patients. Overall mean time from admission decision to virtual huddle decreased from 81 to 61 minutes and mean time to admission from 144 to 115 minutes, with 41% (n = 33) arriving ≤ 60 minutes (goal). The COVID-19 pandemic negatively affected admission timeliness while safety metrics remained optimized. Conclusions: Implementing a standardized admission process between the Clinic and ACCU enhanced safety by reducing admission wait time and escalation of care post-admission. Sustainable, reliable handoff processes, in-clinic monitoring, and standardized admission processes were established. The pandemic hindered admission efficiency without compromising safety.

RESUMO

The transmembrane protein claudin-1 is critical for formation of the epidermal barrier structure called tight junctions (TJ) and has been shown to be important in multiple disease states. These include neonatal ichthyosis and sclerosing cholangitis syndrome, atopic dermatitis and various viral infections. To develop a model to investigate the role of claudin-1 in different disease settings, we used CRISPR/Cas9 to generate human immortalized keratinocyte (KC) lines lacking claudin-1 (CLDN1 KO). We then determined whether loss of claudin-1 expression affects epidermal barrier formation/function and KC differentiation/stratification. The absence of claudin-1 resulted in significantly reduced barrier function in both monolayer and organotypic cultures. CLDN1 KO cells demonstrated decreases in gene transcripts encoding the barrier protein filaggrin and the differentiation marker cytokeratin-10. Marked morphological differences were also observed in CLDN1 KO organotypic cultures including diminished stratification and reduced formation of the stratum granulosum. We also detected increased proliferative KC in the basale layer of CLDN1 KO organotypic cultures. These results further support the role of claudin-1 in epidermal barrier and suggest an additional role of this protein in appropriate stratification of the epidermis.

RESUMO

Subacute thyroiditis (SAT) is a rare form of thyroid disease characterized by fever, neck pain, and dysregulated thyroid hormone levels. It is caused by the post-viral inflammation and destruction of thyroid follicles. Patients typically present with symptoms of hyperthyroidism, as stored thyroid hormone is released into the blood. In this case, we describe a 34-year-old female who presented to the clinic complaining of neck pain and a headache for two days. She endorsed fatigue, myalgias, dizziness, and constipation but denied any fever. She reported only minimal pain relief with ibuprofen and denied a history of recent illness. On exam, she was afebrile and normotensive. Her physical exam was notable for neck tenderness over the right lobe and isthmus of the thyroid, thyromegaly, and a palpable thyroid nodule. Her complete blood count showed no sign of infection or hematologic abnormality, but her thyroid studies showed an elevated thyroid stimulating hormone of 2.1 mIU/L and a decreased thyroxine (T4) level below 0.01 ng/dL. The laboratory results, history, and physical exam led to the diagnosis of the hypothyroid stage of subacute thyroiditis. She was initially treated with ibuprofen 600mg without resolution of her symptoms. She was then treated with prednisone 40mg with symptom relief. This case highlights an atypical presentation of subacute thyroiditis and adds a new presentation to the discussion for patients with this condition.

RESUMO

BACKGROUND: Pregnant patients with preterm prelabor rupture of membranes may experience prolonged hospitalization, which is an indication for pharmacologic venous thromboembolism prophylaxis according to certain international guidelines. The proportion of patients who deliver unexpectedly and within a period during which pharmacologic prophylaxis would be expected to impact coagulation is unknown. OBJECTIVES: To estimate the proportion of patients with preterm prelabor rupture of membranes who would deliver within 12 hours of typical dosing of pharmacologic venous thromboembolism prophylaxis if administered routinely for antepartum admissions >72 hours. STUDY DESIGN: This is a retrospective cohort study from a database including patients admitted for expectant management of preterm prelabor rupture of membranes January 2011-September 2020. The outcome of the study was the proportion of patients who remained undelivered 72 hours after admission and experienced an unplanned delivery potentially within 12 hours of enoxaparin administration. We evaluated patients undelivered after 72 hours due to international recommendations to initiate venous thromboembolism prophylaxis in hospitalized patients after 72 hours. Unplanned delivery was defined as onset of spontaneous labor or other indication for immediate delivery. Timing of delivery was analyzed based on usual timing of enoxaparin administration daily at approximately 8 am and the recommendation to withhold regional anesthesia until 12 hours after a prophylactic dose. RESULTS: 1381 deliveries were identified as preterm prelabor rupture of membranes out of the 49,322 deliveries in our database. 139 cases were included after the following exclusions: delivery >35 weeks (N=641), rupture of membranes >34 weeks (N=145), delivery <72 hours after admission (N=409), insufficient data (N=35), and duplicates (N=12). Sixty of the 139 (43%) had an unplanned delivery, while 33 of these (24% of total) occurred within 12 hours of enoxaparin administration. CONCLUSION: A quarter of patients admitted for preterm prelabor rupture of membranes had an unplanned delivery within 12 hours of typical enoxaparin dosing. This cohort may experience harm (ineligibility for regional anesthesia, risks of general anesthesia, increased risk of bleeding) if given routine pharmacologic venous thromboembolism prophylaxis. Risk/benefit considerations should be discussed with patients in considering pharmacologic versus mechanical prophylaxis during prolonged hospitalization for preterm prelabor rupture of membranes.

RESUMO

OBJECTIVE: To implement the BREASTChoice decision tool into the electronic health record and evaluate its effectiveness. BACKGROUND: BREASTChoice, is a multilevel decision tool that: 1) educates patients about breast reconstruction; 2) estimates personalized risk of complications; 3) clarifies patient preferences; and 4) informs clinicians about patients' risk and preferences. METHODS: A multisite randomized controlled trial enrolled adult women with stage 0-III breast malignancy undergoing mastectomy. Participants were randomized to BREASTChoice or a control website. A survey assessed knowledge, preferences, decisional conflict, shared decision-making, preferred treatment, and usability. We conducted intent-to-treat (ITT), per-protocol (PP) analyses (those randomized to BREASTChoice who accessed the tool), and stratified analyses. RESULTS: 23/25 eligible clinicians enrolled. 369/761 (48%) contacted patients enrolled and were randomized. Patients' average age was 51 years; 15% were older than 65. BREASTChoice participants had higher knowledge than control participants (ITT: mean 70.6 vs. 67.4, P=0.08; PP: mean 71.4 vs. 67.4, P=0.03), especially when stratified by site (ITT: P=0.04, PP: P=0.01), age (ITT: P=0.04, PP: P=0.02), and race (ITT: P=0.04, PP: P=0.01). BREASTChoice did not improve decisional conflict, match between preferences and treatment, or shared decision-making. In PP analyses, fewer high-risk patients using BREASTChoice chose reconstruction. BREASTChoice had high usability. CONCLUSIONS: BREASTChoice is a novel decision tool incorporating risk prediction, patient education, and clinician engagement. Patients using BREASTChoice had higher knowledge; older adults and those from racially minoritized backgrounds especially benefitted. There was no impact on other decision outcomes. Future studies should overcome implementation barriers and specifically examine decision outcomes among high-risk patients.

RESUMO

Predation by invasive species can threaten local ecosystems and economies. The European green crab (Carcinus maenas), one of the most widespread marine invasive species, is an effective predator associated with clam and crab population declines outside of its native range. In the U.S. Pacific Northwest, green crab has recently increased in abundance and expanded its distribution, generating concern for estuarine ecosystems and associated aquaculture production. However, regionally-specific information on the trophic impacts of invasive green crab is very limited. We compared the stomach contents of green crabs collected on clam aquaculture beds versus intertidal sloughs in Willapa Bay, Washington, to provide the first in-depth description of European green crab diet at a particularly crucial time for regional management. We first identified putative prey items using DNA metabarcoding of stomach content samples. We compared diet composition across sites using prey presence/absence and an index of species-specific relative abundance. For eight prey species, we also calibrated metabarcoding data to quantitatively compare DNA abundance between prey taxa, and to describe an 'average' green crab diet at an intertidal slough versus a clam aquaculture bed. From the stomach contents of 61 green crabs, we identified 54 unique taxa belonging to nine phyla. The stomach contents of crabs collected from clam aquaculture beds were significantly different from the stomach contents of crabs collected at intertidal sloughs. Across all sites, arthropods were the most frequently detected prey, with the native hairy shore crab (Hemigrapsus oregonensis) the single most common prey item. Of the eight species calibrated with a quantitative model, two ecologically-important native species-the sand shrimp (Crangon franciscorum) and the Pacific staghorn sculpin (Leptocottus armatus)-had the highest average DNA abundance when detected in a stomach content sample. In addition to providing timely information on green crab diet, our research demonstrates the novel application of a recently developed model for more quantitative DNA metabarcoding. This represents another step in the ongoing evolution of DNA-based diet analysis towards producing the quantitative data necessary for modeling invasive species impacts.

RESUMO

The concurrent seropositivity of HBsAg and anti-HBs has been described among patients with chronic hepatitis B (CHB), but its prevalence is variable. HBV S-gene mutations can affect the antigenicity of HBsAg. Patients with mutations in the 'α' determinant region of the S gene can develop severe HBV reactivation under immunosuppression. In this study at a tertiary liver center in the United States, we evaluated the frequency and virological characteristics of the HBsAg mutations among CHB patients with the presence of both HBsAg and anti-HBs. In this cohort, 45 (2.1%) of 2178 patients were identified to have a coexistence of HBsAg and anti-HBs, and 24 had available sera for the genome analysis of the Pre-S1, Pre-S2, and S regions. The frequency of mutations in the S gene was significantly higher among those older than 50 years (mean 8.5 vs. 5.4 mutations per subject, p = 0.03). Twelve patients (50%) had mutations in the 'α' determinant region of the S gene. Mutations at amino acid position 126 were most common in eight subjects. Three had a mutation at position 133. Only one patient had a mutation at position 145-the classic vaccine-escape mutation. Despite the universal HBV vaccination program, the vaccine-escape mutant is rare in our cohort of predominantly Asian patients.

RESUMO

BACKGROUND: Improving shared decision-making using a treat-to-target approach, including the use of clinical outcome measures, is important to providing high quality care for rheumatoid arthritis (RA). We developed an Electronic Health Record (EHR) integrated, patient-facing sidecar dashboard application that displays RA outcomes, medications, and lab results for use during clinical visits ("RA PRO dashboard"). The purpose of this study was to assess clinician perceptions and experiences using the dashboard in a university rheumatology clinic. METHODS: We conducted focus group (FG) discussions with clinicians who had access to the dashboard as part of a randomized, stepped-wedge pragmatic trial. FGs explored clinician perceptions towards the usability, acceptability, and usefulness of the dashboard. FG data were analyzed thematically using deductive and inductive techniques; generated themes were categorized into the domains of the Technology Acceptance Model (TAM). RESULTS: 3 FG discussions were conducted with a total of 13 clinicians. Overall, clinicians were enthusiastic about the dashboard and expressed the usefulness of visualizing RA outcome trajectories in a graphical format for motivating patients, enhancing patient understanding of their RA outcomes, and improving communication about medications. Major themes that emerged from the FG analysis as barriers to using the dashboard included inconsistent collection of RA outcomes leading to sparse data in the dashboard and concerns about explaining RA outcomes, especially to patients with fibromyalgia. Other challenges included time constraints and technical difficulties refreshing the dashboard to display real-time data. Methods for integrating the dashboard into the visit varied: some clinicians used the dashboard at the beginning of the visit as they documented RA outcomes; others used it at the end to justify changes to therapy; and a few shared it only with stable patients. CONCLUSIONS: The study provides valuable insights into clinicians' perceptions and experiences with the RA PRO dashboard. The dashboard showed promise in enhancing patient-clinician communication, shared decision-making, and overall acceptance among clinicians. Addressing challenges related to data collection, education, and tailoring dashboard use to specific patient populations will be crucial for maximizing its potential impact on RA care.
