ABSTRACT

BACKGROUND AND OBJECTIVES: Few studies have examined trends and disparities in long-term outcome after stroke in a representative US population. We used a population-based stroke study in the Greater Cincinnati Northern Kentucky region to examine trends and racial disparities in poststroke 5-year mortality.

METHODS: All patients with acute ischemic strokes (AISs) and intracerebral hemorrhages (ICHs) among residents ≥20 years old were ascertained using ICD codes and physician-adjudicated using a consistent case definition during 5 periods: July 1993-June 1994 and calendar years 1999, 2005, 2010, and 2015. Race was obtained from the medical record; only those identified as White or Black were included. Premorbid functional status was assessed using the modified Rankin Scale, with a score of 0-1 being considered “good.” Mortality was assessed with the National Death Index. Trends and racial disparities for each subtype were analyzed with logistic regression.

RESULTS: We identified 8,428 AIS cases (19.3% Black, 56.3% female, median age 72) and 1,501 ICH cases (23.5% Black, 54.8% female, median age 72). Among patients with AIS, 5-year mortality improved after adjustment for age, race, and sex (53% in 1993/94 to 48.3% in 2015, overall effect of study year p = 0.009). The absolute decline in 5-year mortality in patients with AIS was larger than what would be expected in the general population (5.1% vs 2.8%). Black individuals were at a higher risk of death after AIS (odds ratio [OR] 1.23, 95% CI 1.08-1.39) even after adjustment for age and sex, and this effect was consistent across study years. When premorbid functional status and comorbidities were included in the model, the primary effect of Black race was attenuated but race interacted with sex and premorbid functional status. Among male patients with a good baseline functional status, Black race remained associated with 5-year mortality (OR 1.4, 95% CI 1.1-1.7, p = 0.002). There were no changes in 5-year mortality after ICH over time (64.4% in 1993/94 to 69.2% in 2015, overall effect of study year p = 0.32).

DISCUSSION: Long-term survival improved after AIS but not after ICH. Black individuals, particularly Black male patients with good premorbid function, have a higher mortality after AIS, and this disparity did not change over time.

ABSTRACT

OBJECTIVE: To examine the specific characteristics of ICG-angiography during various bariatric interventions.

MATERIAL AND METHODS: The study included 329 patients, with 105 (32%) undergoing sleeve gastrectomy (LSG), 98 (30%) undergoing mini-gastricbypass (MGB), 126 (38%) undergoing Roux-en-Y gastric bypass (RGB). Intraoperative ICG angiography was perfomed on all patients at ‘control points’, the perfusion of the gastric stump was qualitatively and quantitatively assessed.

RESULTS: Intraoperative ICG angiography shows that during LSG the angioarchitectonics in the area of the His angle are crucial. The presence of the posterior gastric artery of the gastric main type is a prognostically unfavorable risk factor for the development of ischemic complications. Therefore, to expand the gastric stump it is necessary to suture a 40Fr nasogastric tube and perform peritonization of the staple line. Statistical difference in blood supply at three points were found between and within the two groups of patients (Gis angle area, gastric body, pyloric region) with a p-value <0.001. During MGB, one of the important stages is applying the first (transverse) stapler cassette between the branches of the right and left gastric arteries. This maintains blood supply in anastomosis area, preventing immediate complications such as GEA failure, as well as long-term complications like atrophic gastritis, peptic ulcers, and GEA stenosis.

CONCLUSION: ICG angiography is a useful method for intraoperative assessment of angioarchitecture and perfusion of the gastric stump during bariatric surgery. This helps prevent tissue ischemia and reduce the risk of early and late postoperative complications.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness of intensive therapy for massive intraoperative blood loss in children.

MATERIAL AND METHODS: A retrospective analysis of primary medical records of 39 children with massive intraoperative blood loss was performed. Patients were divided into two groups (younger 1 year (n=18) and older 1 year (n=21)). Each group was divided into two subgroups (blood loss <10% and >100% of total blood volume). We analyzed total intraoperative infusion, qualitative composition of transfusions, reinfusion of washed autologous erythrocytes and vasopressor support. In postoperative period, we assessed hemoglobin, platelets, albumin, fibrinogen, lactate, prothrombin index, duration of mechanical ventilation, severity of organ dysfunction (pSOFA score) after 1 and 3 days, ICU stay and incidence of repeated blood transfusions.

RESULTS: With regard to transfusion volume, we found a general pattern (3 parts of crystalloids, 2 parts of erythrocyte-containing components and 1 part of fresh frozen plasma in all groups with the exception of children older 1 year with blood loss >100% of total blood volume. The last ones had ratio 3:5:1 due to large volume of reinfusion of washed autologous erythrocytes. In all groups, target levels of hemoglobin, platelets, albumin and prothrombin index were achieved. Serum fibrinogen was slightly lower in the group with blood loss >100% of total blood volume. There was a direct relationship between blood loss and ICU stay (Spearman’s test r_s=0.421, p<0.05), as well as duration of mechanical ventilation (Spearman’s test r_s=0.509, p<0.05). Mean pSOFA score upon admission to intensive care unit was 3-4 points in both groups with blood loss <100% of total blood volume. In patients with blood loss >100% of total blood volume, this indicator averaged 9 points and regressed to 3-4 points over the next 72 hours.

CONCLUSION: Intraoperative intensive therapy contribute to minimal severity of postoperative organ dysfunction in children with blood loss < 100% of total blood volume and rapid regression of multiple organ failure in patients with blood loss exceeding this indicator.

ABSTRACT

PURPOSE: To explore the clinical application of one-piece polyetheretherketone (PEEK) removable partial dentures (RPDs) fabricated using a novel digital workflow and to evaluate their weights and fits in vivo and patient satisfaction.

MATERIALS AND METHODS: Fifteen cases with posterior partially edentulous situations were selected, and each patient received two types of RPDs, including a novel digital workflow (test group) and a conventional workflow (control group). For the test group, one-piece RPDs were designed through three-dimensional (3D) methods by scanning stone casts and fabricated by milling PEEK discs. Each RPD was weighed. The gaps between the oral tissue and RPDs in each group were duplicated using a polyvinylsiloxane (PVS) replica and measured by 3D analysis. A visual analog scale (VAS) was used to evaluate the patient’s satisfaction. Paired t-tests were used to compare the differences in the weight, the gaps of each RPD, and VAS values between the two groups. One-way analysis of variance tests was used to compare the differences in the gap among different components in each group.

RESULTS: The RPD in the test group weighed less than that in the control group (p < 0.01). No statistically significant differences in the gaps of denture bases and rests (p > 0.05) were found between the two groups, but the gaps of major connectors in the test group were significantly smaller than in the control group (p < 0.05). The VAS scores for comfortableness and masticatory efficiency were not significantly different between the two groups (p > 0.05) but the scores for the aesthetic appearance of the clasps in the test group were significantly higher than that in the control group (p < 0.05).

CONCLUSIONS: One-piece PEEK RPDs manufactured using a novel digital workflow weighed less than conventional RPDs and exhibited a clinically acceptable internal fit. Although the aesthetic appearance of the PEEK clasps was superior to the control, there is still room for improvement.

ABSTRACT

IMPORTANCE: Chronic pain is a common condition for which efficacious interventions tailored to highly affected populations are urgently needed. People with HIV have a high prevalence of chronic pain and share phenotypic similarities with other highly affected populations.

OBJECTIVE: To evaluate the efficacy of a behavioral pain self-management intervention called Skills to Manage Pain (STOMP) compared to enhanced usual care (EUC).

DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial included adults with HIV who experienced at least moderate chronic pain for 3 months or more. The study was set at the University of Alabama at Birmingham and the University of North Carolina-Chapel Hill large medical centers from August 2019 to September 2022.

INTERVENTION: STOMP combined 1-on-1 skill-building sessions delivered by staff interventionists with group sessions co-led by peer interventionists. The EUC control group received the STOMP manual without any 1-on-1 or group instructional sessions.

MAIN OUTCOMES AND MEASURES: The primary outcome was pain severity and the impact of pain on function, measured by the Brief Pain Inventory (BPI) summary score. The primary a priori hypothesis was that STOMP would be associated with a decreased BPI in people with HIV compared to EUC.

RESULTS: Among 407 individuals screened, 278 were randomized to STOMP intervention (n = 139) or EUC control group (n = 139). Among the 278 people with HIV who were randomized, the mean (SD) age was 53.5 (10.0) years; 126 (45.0%) identified as female, 146 (53.0%) identified as male, 6 (2.0%) identified as transgender female. Of the 6 possible 1-on-1 sessions, participants attended a mean (SD) of 2.9 (2.5) sessions. Of the 6 possible group sessions, participants attended a mean (SD) of 2.4 (2.1) sessions. Immediately after the intervention compared to EUC, STOMP was associated with a statistically significant mean difference for the primary outcome, BPI total score: -1.25 points (95% CI, -1.71 to -0.78 points; P < .001). Three months after the intervention, the mean difference in BPI total score remained statistically significant, favoring the STOMP intervention -0.62 points (95% CI, -1.09 to -0.14 points; P = .01).

CONCLUSION AND RELEVANCE: The findings of this randomized clinical trial support the efficaciousness of STOMP as an intervention for chronic pain in people with HIV. Future research will include implementation studies and work to understand the optimal delivery of the intervention.

ABSTRACT

IMPORTANCE: Since implementation of the International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) in the US, thousands of new or related codes have been added to represent clinical conditions. The widely used pediatric complex chronic condition (CCC) system required a major update from version 2 (V2) to version 3 (V3) to capture the range of clinical conditions represented in the ICD-10-CM.

OBJECTIVE: To update the CCC V3 system, creating V3, with new, missing, or retired codes; to reconceptualize the system’s use of technology codes; and to compare CCC V3 with V2.

DESIGN, SETTING, AND PARTICIPANTS: This repeated cross-sectional study examined US hospitalization data from the Pediatric Health Information System (PHIS) and the Medicaid Merative MarketScan Research Databases from January 1, 2009, to December 31, 2019, for all patients aged 0 to 18 years. Data were analyzed from March 1, 2023, to April 1, 2024.

EXPOSURES: The CCCs were identified in both data sources using the CCC V2 and V3 systems.

MAIN OUTCOMES AND MEASURES: The (1) percentage of pediatric hospitalizations associated with a CCC, (2) numbers of CCC body-system categories per patient, and (3) explanatory power for hospital length of stay and in-hospital mortality were compared over time for V3 vs V2.

RESULTS: Among 7 186 019 hospitalizations within PHIS, 54.3% patients were male, the median age was 4 years (IQR, 1-11 years), and 51.2% were aged 0 to 4 years). The CCC V2 identified 2 878 476 (40.1%) patients as having any CCC compared with 2 753 412 (38.3%) identified by V3. In addition, V2 identified 100 065 (1.4%) patients with transplant status compared with 146 683 (2.0%) by V3, and V2 identified 914 835 (12.7%) as having technology codes compared with 805 585 (11.2%) by V3. The 2 systems were similar in accounting for the number of CCC body-system categories per patient and in explaining variation in hospital length of stay and in-hospital mortality. For both V2 and V3, 10.0% of the variance in hospital length of stay and 12.0% of the variance in in-hospital mortality was explained by the presence of a CCC. Similar patterns were observed when analyzing the 2 999 420 Medicaid Merative MarketScan Research Databases’ hospitalizations (52.3% of patients were male, the median age was 1 year [IQR, 0-12 years], and 62.0% were 0 to 4 years old), except that the percentages of identified CCCs were all lower: V2 identified 758 110 hospitalizations (25.3%) with any CCC compared with 718 100 (23.9%) identified by V3.

CONCLUSIONS AND RELEVANCE: These results suggest that, moving forward, V3 should be used to identify CCCs, and ongoing, frequent updates to V3, using a transparent, structured process, will enable V3 to accurately reflect the evolving spectrum of clinical conditions represented in the ICD-10-CM.

ABSTRACT

IMPORTANCE: Technical skill in complex surgical procedures may affect clinical outcomes, and there is growing interest in understanding the clinical implications of surgeon proficiency levels.

OBJECTIVES: To determine whether surgeon scores representing technical skills of robot-assisted kidney surgery are associated with patient outcomes.

DESIGN, SETTING, AND PARTICIPANTS: This quality improvement study included 10 urological surgeons participating in a surgical collaborative in Michigan from July 2021 to September 2022. Each surgeon submitted up to 7 videos of themselves performing robot-assisted partial nephrectomy. Videos were segmented into 6 key steps, yielding 127 video clips for analysis. Each video clip was deidentified and distributed to at least 3 of the 24 blinded peer surgeons from the collaborative who also perform robot-assisted partial nephrectomy. Reviewers rated technical skill and provided written feedback. Statistical analysis was performed from May 2023 to January 2024.

MAIN OUTCOMES AND MEASURES: Reviewers scored each video clip using a validated instrument to assess technical skill for partial nephrectomy on a scale of 1 to 5 (higher scores indicating greater skill). For all submitting surgeons, outcomes from a clinical registry were assessed for length of stay (LOS) greater than 3 days, estimated blood loss (EBL) greater than 500 mL, warm ischemia time (WIT) greater than 30 minutes, positive surgical margin (PSM), 30-day emergency department (ED) visits, and 30-day readmission.

RESULTS: Among the 27 unique surgeons who participated in this study as reviewers and/or individuals performing the procedures, 3 (11%) were female, and the median age was 47 (IQR, 39-52) years. Risk-adjusted outcomes were associated with scores representing surgeon skills. The overall performance score ranged from 3.5 to 4.7 points with a mean (SD) of 4.1 (0.4) points. Greater skill was correlated with significantly lower rates of LOS greater than 3 days (-6.8% [95% CI, -8.3% to -5.2%]), EBL greater than 500 mL (-2.6% [95% CI, -3.0% to -2.1%]), PSM (-8.2% [95% CI, -9.2% to -7.2%]), ED visits (-3.9% [95% CI, -5.0% to -2.8%]), and readmissions (-5.7% [95% CI, -6.9% to -4.6%]) (P < .001 for all). Higher overall score was also associated with higher partial nephrectomy volume (β coefficient, 11.4 [95% CI, 10.0-12.7]; P < .001).

CONCLUSIONS AND RELEVANCE: In this quality improvement study on video-based evaluation of robot-assisted partial nephrectomy, higher technical skill was associated with lower rates of adverse clinical outcomes. These findings suggest that video-based evaluation plays a role in assessing surgical skill and can be used in quality improvement initiatives to improve patient care.

ABSTRACT

IMPORTANCE: Family-centered care recognizes families as central to child health and well-being and prioritizes clinician collaboration with families to ensure optimal pediatric care and outcomes. Clinician interpersonal sensitivity and communication skills are key to this approach.

OBJECTIVE: To examine perceptions of and factors associated with family-centered care among clinicians working in pediatric and congenital heart care.

DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional study, participants from diverse clinical disciplines (pediatric cardiology, cardiothoracic surgery, nursing, anesthesia, neonatology, intensive care, psychology, and others), completed an online survey between June 2020 and February 2021. Participants included physicians, surgeons, nurses, and allied and mental health professionals at an Australian quaternary pediatric hospital network. Statistical analysis was performed from August 2022 to June 2023.

MAIN OUTCOMES AND MEASURES: Family-centered care across 4 domains (showing interpersonal sensitivity, treating people respectfully, providing general information, and communicating specific information) was measured using the validated Measure of Processes of Care for Service Providers. Clinician burnout (emotional exhaustion, depersonalization, and personal accomplishment), confidence responding to families’ psychosocial needs, and psychological, clinical role, and sociodemographic factors were also assessed. Informed by theory, hierarchical linear regression was used to identify factors associated with family-centered care.

RESULTS: There were 212 clinicians (177 women [84.3%]; 153 nurses [72.2%], 32 physicians [15.1%], 22 allied and mental health professionals [10.4%], 5 surgeons [2.3%]; 170 [80.2%] aged 20-49 years) who participated (55% response rate). Of the 4 family-centered care domains, scores for treating people respectfully were highest and associated with greater clinician confidence responding to families’ psychosocial needs (effect size [β], 0.59 [95% CI, 0.46 to 0.72]; P < .001), lower depersonalization (β, 0.04 [95% CI, -0.07 to -0.01]; P = .02), and a greater sense of personal accomplishment at work (β, 0.02 [95% CI, 0.01 to 0.04]; P = 0.04). Greater interpersonal sensitivity was associated with greater confidence responding to families’ psychosocial needs (β, 0.80 [95% CI, 0.62 to 0.97]; P < .001), a greater sense of personal accomplishment at work (β, 0.03 [95% CI, 0.01 to 0.05]; P = .04), and lower use of approach-based coping, such as problem-solving (β, 0.37 [95% CI, -0.71 to -0.02]; P = .04).

CONCLUSIONS AND RELEVANCE: In this cross-sectional study, burnout and confidence responding to families’ psychosocial needs were associated with clinicians’ perceptions of family-centered care. These findings suggest that targeted interventions to address these factors may benefit clinicians and also potentially strengthen the practice of family-centered care in pediatric and congenital heart settings.

ABSTRACT

IMPORTANCE: Classifying hospitals across a wide range of pediatric capabilities, including medical, surgical, and specialty services, would improve understanding of access and outcomes.

OBJECTIVE: To develop a classification system for hospitals’ pediatric capabilities.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included data from 2019 on all acute care hospitals with emergency departments in 10 US states that treated at least 1 child per day. Statistical analysis was performed from September 2023 to February 2024.

EXPOSURE: Pediatric hospital capability level, defined using latent class analysis. The latent class model parameters were the presence or absence of 26 functional capabilities, which ranged from performing laceration repairs to performing organ transplants. A simplified approach to categorization was derived and externally validated by comparing each hospital’s latent class model classification with its simplified classification using data from 3 additional states.

MAIN OUTCOMES AND MEASURES: Health care utilization and structural characteristics, including inpatient beds, pediatric intensive care unit (PICU) beds, and referral rates (proportion of patients transferred among patients unable to be discharged).

RESULTS: Using data from 1061 hospitals (716 metropolitan [67.5%]) with a median of 2934 pediatric ED encounters per year (IQR, 1367-5996), the latent class model revealed 4 pediatric levels, with a median confidence of hospital assignment to level of 100% (IQR, 99%-100%). Of 26 functional capabilities, level 1 hospitals had a median of 24 capabilities (IQR, 21-25), level 2 hospitals had a median of 13 (IQR, 11-15), level 3 hospitals had a median of 8 (IQR, 6-9), and level 4 hospitals had a median of 3 (IQR, 2-3). Pediatric level 1 hospitals had a median of 66 inpatient beds (IQR, 42-86), level 2 hospitals had a median of 16 (IQR, 9-22), level 3 hospitals had a median of 0 (IQR, 0-6), and level 4 hospitals had a median of 0 (IQR, 0-0) (P < .001). Level 1 hospitals had a median of 19 PICU beds (IQR, 10-28), level 2 hospitals had a median of 0 (IQR, 0-5), level 3 hospitals had a median of 0 (IQR, 0-0), and level 4 hospitals had a median of 0 (IQR, 0-0) (P < .001). Level 1 hospitals had a median referral rate of 1% (IQR, 1%-3%), level 2 hospitals had a median of 25% (IQR, 9%-45%), level 3 hospitals had a median of 70% (IQR, 52%-84%), and level 4 hospitals had a median of 100% (IQR, 98%-100%) (P < .001).

CONCLUSIONS AND RELEVANCE: In this cross-sectional study of hospitals from 10 US states, a system to classify hospitals’ pediatric capabilities in 4 levels was developed and was associated with structural and health care utilization characteristics. This system can be used to understand and track national pediatric acute care access and outcomes.

ABSTRACT

IMPORTANCE: Misaligned dietary rhythmicity has been associated with metabolic diseases; however, its association with mental health remains largely unexplored.

OBJECTIVE: To examine the association between dietary rhythms and the mental health condition of shift workers, specifically airline crew members.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study analyzed data collected from the Civil Aviation Health Cohort of China, an ongoing large-scale health survey of pilots, flight attendants, and air security officers employed by major airline companies in China. Participants aged 18 to 60 years were invited through text messages to complete a web-based survey. The data collection period was December 2022 to March 2023. Statistical analysis was performed from July 24, 2023, to April 12, 2024.

EXPOSURE: Data on timing of breakfast and dinner on workdays and rest days, daily time windows for food intake, and meal and eating jet lags were collected and calculated.

MAIN OUTCOMES AND MEASURES: Anxiety and depressive symptoms were measured using the 7-item Generalized Anxiety Disorder Assessment and the 9-item Patient Health Questionnaire. Multivariate logistic regressions were performed to evaluate the associations of anxiety and depression with meal timing, eating window time, meal jet lag (ie, delayed meals), and eating jet lag (ie, delayed eating). All models were adjusted for individual socioeconomic, demographic, and lifestyle characteristics.

RESULTS: Of the 22 617 participants (median [IQR] age, 29.1 [26.3-33.7] years; 13 712 males [60.6%]), 1755 (7.8%) had anxiety and 2768 (12.2%) had depression. After controlling for confounding factors, having dinner after 8 pm on morning-shift days was associated with increased odds of anxiety (adjusted odds ratio [AOR], 1.78; 95% CI, 1.53-2.05) and depression (AOR, 2.01; 95% CI, 1.78-2.27), compared with consuming dinner before 8 pm. Similar results were observed on night-shift days and rest days. An eating window of less than 12 hours was associated with reduced odds of anxiety (AOR, 0.84; 95% CI, 0.75-0.93) and depression (AOR, 0.81; 95% CI, 0.75-0.89) on morning-shift days; the results remained significant on rest days. Delayed dinner on morning-shift days was associated with increased odds of anxiety (AOR, 1.32; 95% CI, 1.13-1.54) and depression (AOR, 1.39; 95% CI, 1.22-1.58). On night-shift days, delayed dinner was associated with higher odds of anxiety (AOR, 1.22; 95% CI, 1.06-1.39) and depression (AOR, 1.21; 95% CI, 1.08-1.36). On morning-shift days, delayed eating rhythms were associated with higher odds of depression (AOR, 1.35; 95% CI, 1.13-1.61), whereas advanced eating rhythms were associated with lower odds of anxiety (AOR, 0.78; 95% CI, 0.70-0.87).

CONCLUSIONS AND RELEVANCE: This cross-sectional study found that meal timing, long eating window, and meal jet lags were associated with increased odds of depression and anxiety. These findings underscore the need for interventions and supportive policies that help mitigate the adverse implications of shift work and irregular working hours for the mental health of shift workers.
