The Epidemiology of Midline-Associated Bloodstream Infections in an Urban Healthcare System

This study sought to determine the incidence and characteristics of midline-associated bloodstream infections (MABSI) at an urban health system during the COVID-19 pandemic. A MABSI rate similar to the central line-associated bloodstream infection (CLABSI) rate was found. A large number of MABSI were caused by Staphylococcus spp. and Enterococcus spp., as has previously been reported for CLABSI. Patients with MABSI had high in-hospital mortality rates.

Determinants of under-five mortality in informal settlements in Nairobi, Kenya from 2002 to 2018

BackgroundChildhood mortality persists as a significant public health challenge in low and middle-income countries and is uneven within countries, with poor communities such as urban informal settlements bearing the highest burden. There is limited literature from urban informal settlements on the risk factors of mortality. We assessed under-five mortality and associated risk factors from the period 2002 to 2018 in Nairobi urban informal settlements.MethodsWe used secondary data from the Nairobi Urban Health and Demographic Surveillance System (NUHDSS), a longitudinal surveillance platform that routinely collects individual and household-level data in two informal settlements (Viwandani and Korogocho) in Nairobi, Kenya. We used Kaplan-Meier curves to estimate overall survival and the Cox proportional hazard model with a frailty term to evaluate the impact of risk factors on survival time.ResultsOverall under-five survival rate was 96.8% and this improved from 82.6% (2002-2006) to 95% (2007-2012) and 98.4% (2012-2018). There was a reduced risk of mortality among children who had BCG vaccination, those born to a married mother or a mother not engaging in any income-generating activity (both from 2007 to 2011), children from singleton pregnancy, children born in Viwandani slum and ethnicity of the child.ConclusionUnder-five mortality is still high in urban informal settlements. Targeted public health interventions such as vaccinations and interventions empowering women such as single mothers, those with multiple pregnancies, and more impoverished slums are needed to further reduce under-five mortality in urban informal settlements.

Promoting Resilience in Healthcare Workers: A Preventative Mental Health Education Program.

Healthcare workers face greater risks for mental health conditions and chronic stress due to the demanding nature of their roles. The COVID-19 pandemic exacerbated these challenges and increased vulnerabilities to long-term mental health conditions. The present study adapts an existing resilience-based educational workshop program to address the time constraints and unique needs of the healthcare workforce in a post-COVID-19 world. Expanded from its initial focus on resilience, the workshop curriculum incorporates psychoeducation on common mental health issues. Between July 2022 and June 2024, a 15 min "huddle" format offered on-site training to equip HCWs in a large urban health system with coping strategies to prevent, manage, and recover from stress. Attendance and anonymous feedback were collected at each session via brief electronic surveys. Participant responses (n = 1403) obtained immediately post-huddle suggested positive impact on stress management, perceived leadership support, and resilience. Findings show the potential of brief huddles to improve mental health and resilience in healthcare workers and similar workforces. Our findings support the efficacy of brief, evidence-based educational huddles in enhancing resilience, mental health awareness, and coping skills among HCWs. This model holds significant potential for widespread implementation across healthcare and other high-stress workplaces.

Feasibility, acceptability, and fidelity of remote-delivered abbreviated mindfulness-based cognitive therapy interventions for patients with migraine and depressive symptoms.

This study was an open-label single-arm clinical trial evaluating the fidelity, feasibility, acceptability, and clinical signal of abbreviated mindfulness-based cognitive therapy (MBCT-brief) delivered either via telephone (MBCT-T) or by video conferencing (MBCT-V) for people with migraine and comorbid depressive symptoms. Migraine is commonly comorbid with elevated depressive symptoms. MBCT reduces depressive symptoms and shows promise to reduce migraine-related disability. An abbreviated and remotely delivered version of MBCT could increase access to care. People with migraine and elevated depressive symptoms were recruited from a large urban health system. Participants were assigned in blocks of eight to receive an evidence-based MBCT-brief treatment, including eight weekly group classes and home practice delivered via telephone (MBCT-T) or video (MBCT-V); MBCT-T was randomly selected for the first block. Sessions were recorded and coded for treatment fidelity. Feasibility was assessed via session attendance (primary), homework completion, recruitment rate, and survey completion rate. Acceptability was assessed via the eight-item Client Satisfaction Questionnaire (CSQ-8; primary), the Credibility/Expectancy Questionnaire (CEQ), the System Usability Scale (SUS), and items assessing survey acceptability. Participants completed the Headache Disability Inventory (HDI) and Quick Inventory of Depressive Symptomatology-Self Report 16-item (QIDS-SR16) at baseline, mid-treatment, and post-treatment. Feasibility and acceptability rates were compared to a priori benchmarks. Participants (n = 16) were all female with a mean (standard deviation [SD]) age of 45 (13) years, the majority of whom identified as White (13/16, 81%) and non-Hispanic (14/16, 88%). The intervention met the a priori criteria set for therapist fidelity to treatment protocol (mean [SD] MBCT-Treatment Acceptability and Competence Scale Adherence score 2.9 [0.2]), feasibility (mean [SD] session attendance was 7.9/8 [0.3]), and acceptability (mean [SD] CSQ-8 score 28.8 [3.3]) for the entire sample and for each treatment arm. The usability of the remote-delivery system was high across study participants (mean [SD] SUS score 84.8 [11.0]). Survey procedures were broadly deemed acceptable, with at least 80% participants either endorsing "Agree" or "Strongly Agree" across all items. Using Wilcoxon tests, we observed significant reductions in both the HDI (pre-treatment median [interquartile range] score 63 [40, 70] vs. post-treatment 36 [26, 54], p = 0.004) and the QIDS-SR16 (pre-treatment median [interquartile range] score 8 [5, 13] vs. post-treatment 4 [3, 6], p = 0.003). We found that remotely delivered MBCT-brief for migraine and depressive symptoms was feasible and acceptable to patients in both the telephone and video modalities. Intervention was associated with significant post-treatment reductions in headache-related disability and depressive symptomatology, findings that must be interpreted cautiously in the absence of a control group.

5099 Capturing the Patient Voice for Diabetes Eye Exams

Abstract Disclosure: S. Du: None. S. Lambrechts: None. M. Freeby: None. M. Han: None. Background: Diabetic retinopathy (DR) is a leading cause of blindness among adults 20-74 years old. Ophthalmic exams are recommended every 1-2 years for type 2 diabetes patients with minimal to no DR. The 50th percentile Integrated Healthcare Association benchmark for DR screening is 49%, but at our academic medical center, the completion rate is 30%. Potential barriers to screening noted in the literature include lower levels of education, lack of knowledge about DR, and financial barriers. Objective: To understand motivating factors and barriers to DR screening among patients in our health system. Methods: We utilized the Patient Voice qualitative research method to uncover themes and identify interventions to improve care delivery. The literature was synthesized to develop a structured interview guide. From our urban academic health system, 15 patients were randomly selected for interview, six of whom had completed the “Diabetes Eye Exam” care gap and nine that had not. Interviews were transcribed and coded for thematic analysis. Results: Six opportunity areas were identified. 1) There are currently only six retinal cameras located across primary and specialty care clinics serving more than 38,000 diabetes patients. 67% of patients felt the current clinic locations were inconvenient, with distant locations and long travel times. 2) 20% of patients expressed that they would like increased flexibility of appointments offered, such as evening, weekend, and same day appointments. 3) Patients were motivated by automated diabetes eye exam specific reminder messages and appreciated the ability to self-schedule within the patient portal. 47% of patients wanted yearly reminder messages, while 40% had no preference. 4) 53% of patients expressed that they did not fully understand DR or were confused about the difference between an optometrist exam and diabetes eye exam. 5) 40% of patients completed their eye exam with their local optometrist and found this to be a more convenient option. One patient expressed that she wished her doctor had informed her that she could complete her diabetes eye exam at a local optometry clinic. 6) If patients do choose to complete their exam with their local optometrist, they would like reminders to send their records to their primary care physician or endocrinologist. A more streamlined processes to upload outside records through the patient portal would decrease this barrier. Conclusion: It is important to engage patient stakeholders and understand their needs to improve overall experience and close care gaps. Through the Patient Voice, we learned that factors such as driving distance, traffic, scheduling, and issues with uploading records are major barriers to care gap completion. Convenient clinic locations, education, and reminder messages are motivating factors. Future work will focus on developing and implementing solutions in each opportunity area. Presentation: 6/1/2024

Outcomes of patients with cancer cared for in a multisite home hospital program.

394 Background: Home hospital provides hospital-level care for acutely ill patients in their homes as a substitute for care in brick-and-mortar hospitals. Since the Centers for Medicare and Medicaid Services’ acute hospital care at home waiver in November 2020, 330 hospitals have received approval to launch home hospital programs. Prior research has shown that patients cared for in home hospital have improved physical activity, and lower mortality and readmission rates. However, many of these programs exclude patients with cancer, and data describing outcomes of patients with cancer cared for in home hospital programs are limited. Methods: We identified patients admitted to a multisite home hospital program affiliated with an urban health system between February 1, 2020 and May 1, 2024 who had a diagnosis of cancer (ICD-10: C00-C96) or myelodysplastic syndrome (ICD-10: D46) managed by an oncologist within the health system. For each admission we conducted chart reviews to determine whether the malignancy was active at the time of admission, defined by ongoing antineoplastic treatment or an admission directly related to the malignancy. We also captured the patient’s cancer diagnosis, the admission diagnosis, total length of stay, and length of time in home hospital. We identified readmissions within 30 days of discharge and escalations of care, defined as a return to a brick-and-mortar hospital for additional care spanning at least one midnight, and calculated rates of these outcomes. Results: There were 141 home hospital admissions among 128 patients with cancer diagnoses (mean age: 77, 36% female). The most common oncologic diagnoses were lymphoma (16%, N = 22), chronic leukemias and MDS (14%, N = 20), and lung cancer (13%, N = 18). Seventy-one patients (50%) had active cancer at the time of admission. The leading admission diagnoses were pneumonia (N = 28, 16%), heart failure exacerbations (N = 19, 13%), complicated urinary tract infections (N = 12, 9%) and soft tissue infections (N = 10, 7%). The mean total length of stay was 7.9 days (SD 5.6) and patients were admitted to home hospital for a mean of 4.9 days (SD: 3.5). Escalation rates and 30-day readmission rates were 7% (N = 10) and 13% (N = 19), respectively, among all patients, and 5% (N = 4) and 14% (N = 10) among patients with active malignancies. Conclusions: These data describe a cohort of patients with cancer cared for in a multisite home hospital program. They show low rates of transfer back to brick-and-mortar hospitals and low 30-day readmission rates, and they demonstrate that patients with cancer can be safely cared for in a home hospital. As home hospital programs build new capabilities, a larger proportion of oncology patients will be eligible for home hospital. More work is needed to estimate risk-adjusted outcomes among these populations and to understand the patient and caregiver experience with oncology home hospital.

Risk Factors for the Development of Ocular Complications in Herpes Zoster Ophthalmicus and Zoster Vaccine Utilization in a Large, Urban Health System

To characterize the epidemiology of herpes zoster (HZ) and herpes zoster ophthalmicus (HZO) in an urban hospital system and determine risk factors associated with developing ocular complications in HZO. To report the frequency of shingles vaccination and HZ reactivation following shingles vaccination in this population. A retrospective cohort study was conducted on patients seen at the University of Illinois Hospital system from January 1, 2010 to December 1, 2021 with HZ and HZO identified by diagnosis code. Charts of HZO patients seen within 1 year of diagnosis were abstracted. Multivariable logistic regression analysis identified factors associated with the development of ocular complications in HZO. During the study period, 3283 patients had HZ; mean age of onset was 52.3 years, 61.6% were female, and 37% were Black. HZO with ocular involvement was seen in 110 (3.4%) patients. Ocular complications developed in 40 (36.4%) patients; the most common complication was corneal scarring (70%). Age (odds ratio [OR] 1.04, 95%CI 1.0-1.1), female gender (OR 2.86, 95%CI 1.0-8.1), steroids at initial visit (4.46, 95%CI 1.4-14.6), and stromal keratitis (OR 3.45, 95% CI 1.2, 9.8) were associated with developing ocular complications. Of eligible populations, 5333 (1.5%) received shingles vaccination; 43 patients developed reactivation of HZ following vaccination. In HZO, age, female gender, steroids at initial visit, and stromal keratitis are strongly associated with developing ocular complications. Shingles vaccination rates were low in this study population. Understanding potential for complications in HZ/HZO and vaccination uptake can help identify at risk populations to prevent disease.

326 A Retrospective Chart Review of Patients Presenting With Heat-Related Illness to an Urban Health System in Phoenix, Arizona Over One Decade

Abstract B148: Prevalence of Multimorbidity Among Patients with Newly Diagnosed Cancer at a Safety-Net Health System

Abstract Background: Multimorbidity (MM) presents challenges for cancer care and may require coordination between oncologists and primary or specialty care providers. Nevertheless, U.S.-based studies of MM among cancer patients have mostly been conducted in non-Hispanic White and insured populations, which limits understanding of strategic care planning and resource allocation among more diverse populations. Therefore, we aimed to assess the prevalence of MM among adults with newly diagnosed cancer at a large, racial/ethnically diverse safety-net health system. Methods: We used electronic health record and cancer registry data from JPS Health Network, an urban safety-net health system in North Texas. Our eligible population included patients ≥18 years of age diagnosed with first primary cancer in 2016 – 2020 (excluding in situ cases), whose diagnosis or first-course cancer treatment was received at JPS. Our outcomes of interest were MM (≥2 chronic conditions) and severe MM (≥3 chronic conditions) based on 30 chronic conditions defined by the Centers for Medicare & Medicaid Services with up to a 2-year lookback period before cancer diagnosis. We assessed overall and sub-group specific (age group, sex, and race/ethnicity) prevalence of MM and severe MM. We estimated prevalence differences (PD) and 95% confidence intervals between groups using pairwise comparisons with Bonferroni correction. Results: Our study population comprised 5,019 newly diagnosed adult cancer patients. The median age was 58 years and the majority were females (51%), racial/ethnic minorities (59%), uninsured (51%), and overweight or obese (69%). The most common cancer types were breast (13%), lung (12%), and colorectal (11%). Nearly half (45%) were diagnosed with advanced stage cancer. A high proportion of cancer patients had MM (79%) and severe MM (62%). The most common conditions were hypertension (55%), anemia (36%), hyperlipidemia (31%), diabetes (27%), and depressive mood disorders (22%). MM increased by age: 56% among patients aged 18 – 39 years, 78% among patients aged 40 – 64 years, and 91% among patients aged ≥65 years. A higher proportion of males had MM (PD: 6.0% [95% CI: 3.8%, 8.3%]) and severe MM (PD: 7.5% [95% CI: 4.9%, 10%]) compared with females. By race/ethnicity, Non-Hispanic Black patients had the highest prevalence of MM (PD: 8.1% [95% CI: 4.3%, 12%]) and severe MM (PD: 11% [95% CI: 6.7%, 16%]) compared with the lowest prevalences among Hispanic patients. Conclusions: We observed a high prevalence of MM and severe MM among adult cancer patients, particularly among patients aged ≥45 years and non-Hispanic Black patients. Our estimates were >15% higher than prior studies that included mostly non-Hispanic White adult cancer survivors with higher socioeconomic status. Our findings provide insight about the burden of MM among racially diverse cancer patients with low socioeconomic status, which may inform resource allocation and care coordination initiatives to manage MM.

Clinician Perspectives on Palliative Care for Older Adults With Serious Mental Illnesses: A Multisite Qualitative Study

ObjectivesApproximately 5.5% of the population live with serious mental illnesses (SMI). Older adults with SMI experience a high burden of serious medical illnesses and disparities in advance care planning, symptom management, and caregiver support. The objectives of this study are to explore interdisciplinary clinician perspectives on the palliative care needs of older adults with SMI and serious medical illnesses. Design, setting, and participantsThis qualitative study utilized thematic analysis of semi-structured interviews of interdisciplinary clinicians practicing palliative care, geriatrics, or geriatric/consultation-liaison psychiatry at four hospitals within an urban health system. MeasurementsThemes related to care of older adults with serious mental illness and serious medical illness with respect to clinician experiences, challenges in care, and opportunities to improve care. ResultsThe authors interviewed 45 clinicians. Major themes identified were: (1) Current paradigms of palliative care do not meet the needs of patients with SMI; (2) Clinicians are motivated to care for this population but require more training and interdisciplinary practice; (3) There is a need for structural integration of psychiatric and palliative care services. ConclusionsThe study underscores the inadequacy of current palliative care models in meeting the unique needs of older adults with SMI. Models of integrated psychiatric and serious illness care and enhanced training are needed to improve the delivery of palliative care. Integrated care models and workforce development at the interface of serious illness care and psychiatric have the potential to improve outcomes for this vulnerable population.

Evaluating the Risk of Venous Thromboembolism in Transfeminine and Gender Diverse People: A Retrospective Analysis

ObjectiveThe risk of venous thromboembolism (VTE) with feminizing gender-affirming hormone therapy is an area of concern. This analysis aimed to assess whether gender-affirming hormone therapy and other potential risk factors are associated with VTE in transfeminine and gender diverse individuals. MethodsWe conducted a chart review of 2126 transfeminine and gender diverse adults receiving care within a large urban health system. The primary outcomes were the prevalence of VTE and odds ratios for the association of VTE with insurer, use of estrogen, and select comorbidities. ResultsA history of VTE was documented in 0.8% of the cohort. Those with a history of VTE were older (P < .001), more often self-identified as Hispanic or Black compared to White or Asian (P < .05) and were more likely to have Medicaid or Medicare (P < .01) when compared to those without a history of VTE. The prevalence of hyperlipidemia (P < .001), diabetes mellitus (P < .05), and hypercoagulable conditions (P < .001) were all greater in the positive VTE group. Hyperlipidemia (P < .001), diabetes mellitus (P < .05), and insurer (P < .05) were associated with increased odds of VTE in univariate analyses. None of the exposure variables analyzed were associated with VTE when controlling for age, race, and the number of comorbidities. ConclusionsThe prevalence of VTE in our cohort was lower than previously observed. VTE was not associated with any one risk factor, including estrogen use, when controlling for age, race, and the number of comorbidities. Those of advanced age and those with multiple cardiometabolic comorbidities may benefit from increased surveillance and mitigation of modifiable risk factors.

Patient and clinic staff perspectives on the implementation of a long-acting injectable antiretroviral therapy program in an urban safety-net health system

BackgroundLong-acting injectable cabotegravir plus rilpivirine (LAI CAB/RPV) has several potential benefits over daily oral formulations for HIV treatment, including the potential to facilitate long-term adherence and reduce pill fatigue. We aimed to assess facilitators of and barriers to LAI CAB/RPV implementation and delivery through the perspectives of physicians and clinical staff, and the experiences of LAI CAB/RPV use among people living with HIV (PLWH) at a Ryan-White supported safety-net clinic in North Texas.MethodsWe conducted semi-structured interviews with recruited clinic staff (physicians, nurses, and support staff) involved with LAI CAB/RPV implementation and PLWH who switched to LAI CAB/RPV and consented to participate in individual interviews. Data were collected from July to October 2023. Our interview guide was informed by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM), and Proctor Implementation Outcomes frameworks. Qualitative data were analyzed using a rapid qualitative analysis approach to summarize key themes.ResultsWe recruited and interviewed 15 PLWH who transitioned to LAI CAB/RPV and 11 clinic staff serving these patients. PLWH conveyed that emotional and informational support from family or a trusted clinician influenced their decision to switch to LAI CAB/RPV. PLWH also reported that injectable treatment was more effective, convenient, and acceptable than oral antiretroviral therapy. Clinic staff and physicians reported that staff training, pharmacist-led medication switches, flexible appointments, refrigeration space and designated room for injection delivery facilitated implementation. Clinic staff cited medication costs, understaffing, insurance prior authorization requirements, and lack of medication access through state drug assistance programs as critical barriers.ConclusionsOur study offers insights into real-world experiences with LAI usage from the patient perspective and identifies potential strategies to promote LAI CAB/RPV uptake. The barriers to and facilitators of LAI CAB/RPV program implementation reported by clinic staff in our study may be useful for informing strategies to optimize LAI CAB/RPV programs.

Eliciting patient past experiences of healthcare discrimination as a potential pathway to reduce health disparities: A qualitative study of primary care staff.

To understand whether and how primary care providers and staff elicit patients' past experiences of healthcare discrimination when providing care. Twenty qualitative semi-structured interviews were conducted with healthcare staff in primary care roles to inform future interventions to integrate data about past experiences of healthcare discrimination into clinical care. Qualitative study. Data were collected via semi-structured qualitative interviews between December 2018 and January 2019, with health care staff in primary care roles at a hospital-based clinic within an urban safety-net health system that serves a patient population with significant racial, ethnic, and linguistic diversity. Providers did not routinely, or in a structured way, elicit information about past experiences of healthcare discrimination. Some providers believed that information about healthcare discrimination experiences could allow them to be more aware of and responsive to their patients' needs and to establish more trusting relationships. Others did not deem it appropriate or useful to elicit such information and were concerned about challenges in collecting and effectively using such data. While providers see value in eliciting past experiences of discrimination, directly and systematically discussing such experiences with patients during a primary care encounter is challenging for them. Collecting this information in primary care settings will likely require implementation of multilevel systematic data collection strategies. Findings presented here can help identify clinic-level opportunities to do so.

Patient perspectives on primary care behavioral health integration in an urban mental health professional shortage area: Benefits, facilitators, and barriers.

While studies have described the benefits of integrating behavioral health (BH) into primary care (PC), few have examined patients' perspectives, especially in large, urban health systems. In 2015, the University of Chicago Medicine launched the Primary Care Behavioral Health Integration Program, located in a mental health professional shortage area. In 2021, semistructured interviews were conducted with adult patients who had discussed their depression symptoms with their primary care clinician (PCC). Participants were asked about their experiences of being screened for depression, discussing BH, and being referred to behavioral health clinicians (BHCs). Interviews were analyzed using thematic analysis and constant comparison, and they were conducted until theme saturation was achieved. Fifteen participants were interviewed, the majority of whom were women and African American/Black, with an average age of 52. Participants expressed that PC-BH integration helps patients recognize BH problems and navigate the BH care system, emphasizes the connection between physical and mental health, and eases conversations through familiar setting and established trust. Patients enumerated barriers to integration, including barriers to BH care in the PC setting, barriers to BH conversations with PCCs/BHCs, and barriers to referrals to psychiatry/external therapy. Patients highlighted facilitators of integration, including trust with their PCC, collaboration between PCCs and BHCs, and population-level screening. These perspectives affirm the core strength of PC-BH integration: making BH more accessible and destigmatizing, especially for underserved communities. They also emphasize the importance of collaboration between PCCs and BHCs, shared identities, and actively involving patients in program design and quality improvement interventions.

The interdependence between hospital choice and waiting time — with a case study in urban China

Hospital choice models often employ random utility theory and include waiting time as a choice determinant. When applied to evaluate health system improvement interventions, these models disregard that hospital choice in turn is a determinant of waiting time. We present a novel, general model capturing the endogeneous relationship between waiting time and hospital choice, including the choice to opt out, and characterize the unique equilibrium solution of the resulting convex problem. We apply the general model in a case study on the urban Chinese health system, specifying that patient choice follows a multinomial logit (MNL) model and waiting times are determined by M/M/1 queues. The results reveal that analyses which solely rely on MNL models overestimate the effectiveness of present policy interventions and that this effectiveness is limited. We explore alternative, more effective, improvement interventions.

Medications that Regulate Gastrointestinal Transit Influence Inpatient Blood Glucose.

A multitude of factors affect a hospitalized individual's blood glucose (BG), making BG difficult to predict and manage. Beyond medications well established to alter BG, such as beta-blockers, there are likely many medications with undiscovered effects on BG variability. Identification of these medications and the strength and timing of these relationships has potential to improve glycemic management and patient safety. EHR data from 103,871 inpatient encounters over 8 years within a large, urban health system was used to extract over 500 medications, laboratory measurements, and clinical predictors of BG. Feature selection was performed using an optimized Lasso model with repeated 5-fold cross-validation on the 80% training set, followed by a linear mixed regression model to evaluate statistical significance. Significant medication predictors were then evaluated for novelty against a comprehensive adverse drug event database. We found 29 statistically significant features associated with BG; 24 were medications including 10 medications not previously documented to alter BG. The remaining five factors were Black/African American race, history of type 2 diabetes mellitus, prior BG (mean and last) and creatinine. The unexpected medications, including several agents involved in gastrointestinal motility, found to affect BG were supported by available studies. This study may bring to light medications to use with caution in individuals with hyper- or hypoglycemia. Further investigation of these potential candidates is needed to enhance clinical utility of these findings. This study uniquely identifies medications involved in gastrointestinal transit to be predictors of BG that may not well established and recognized in clinical practice.

Impact of Prostate-Specific Antigen Screening Pattern on Prostate Cancer Mortality Among Non-Hispanic Black and Non-Hispanic White Men: A Large, Urban Health System Cohort Analysis.

Randomized studies assessing the effect of PSA screening on mortality in non-Hispanic Black (NHB) men are lacking. We aimed to assess the association between PSA screening and survival among NHB men in comparison to non-Hispanic White (NHW) men in a racially diverse real-world North American population. The study cohort included 6378 men who self-identified as NHB or NHW and were diagnosed with prostate cancer (PCa). Patients received PSA screening and subsequent PCa treatment and follow-up at our institution. Patients were sorted based on PSA testing intensity for the 5 years prior to diagnosis, as follows: never, some (<1 test/y), and annual testing (1 test/y). The primary outcome was risk of prostate cancer-specific mortality (PCSM). Competing risk cumulative incidence curves estimated PCSM rates. Competing risk regression analyses examined the impact of PSA testing on PCSM. An interaction term was incorporated to assess the impact of race on the outcome. Median (IQR) age and PSA at diagnosis were 67 (60-73) years and 5.8 (4.4-9.6) ng/mL, respectively, and 2929 (46%) men were NHB (Kruskal-Wallis P values < .001). Annual PSA testing was more frequent in NHW (5%) than in NHB (3%) men (χ2 P value < .001). On cumulative incidence analysis, in the never, some, and annual PSA testing groups, the 10-year PCSM was respectively 12.3%, 5.8%, and 4.6% in NHW and 18.5%, 7%, and 1.2% in NHB patients (Gray's test P values < .001). At competing risk regression, PSA screening rate was associated with more favorable PCSM rates (HR: 0.47; 95% CI 0.33-0.68; P < .001). The interaction term for race did not show statistical significance (P = .2). PSA testing was associated with a reduced risk of PCSM in both NHB and NHW men diagnosed with PCa. Additionally, the positive impact of the screening rate seemed to be independent of race.

Low-Dose Buprenorphine Initiation for Hospitalized Patients With Chronic Pain and Opioid Use Disorder or Opioid Misuse: Protocol for an Open-Label, Parallel-Group, Effectiveness-Implementation Randomized Controlled Trial.

Buprenorphine is an effective medication for both opioid use disorder (OUD) and chronic pain (CP), but transitioning from full opioid agonists to buprenorphine, a partial opioid agonist, can be challenging. Preliminary studies suggest that low-dose buprenorphine initiation can overcome some challenges in starting treatment, but no randomized controlled trials have compared low-dose and standard buprenorphine initiation approaches regarding effectiveness and safety or examined implementation in hospital settings. In a pragmatic open-label hybrid type I effectiveness-implementation trial based in a single urban health system, 270 hospitalized patients with (a) CP and (b) OUD or opioid misuse are being randomized to buprenorphine treatment initiation using 5-day low-dose or standard initiation protocols. Outcomes include buprenorphine treatment uptake (primary), defined as receiving buprenorphine treatment 7 days after enrollment, and other OUD and pain outcomes at 1-, 3-, and 6-month follow-up (secondary). Data collection will also include safety measures, implementation of low-dose initiation protocols, patient acceptability, and cost-effectiveness. Comparing strategies in a randomized clinical trial will provide the most definitive data to date regarding the effectiveness and safety of low-dose buprenorphine initiation. The study will also provide important data on treating CP at a time that clinical guidelines are evolving to center buprenorphine as a preferred opioid for CP.

Childcare needs as a barrier to healthcare among women in a safety-net health system

BackgroundChildcare needs are an understudied social determinant of health. The effect of childcare needs on access to healthcare must be understood to inform health system interventions and policy reform. This study sought to characterize childcare needs, access to childcare, and prior experience with navigating childcare needs in healthcare settings among women in a safety-net population.MethodsWe conducted a cross-sectional study of patient-reported survey data collected in-person between April and October 2019. Surveys were administered in waiting rooms of ambulatory services in a large, urban safety-net health system in Dallas, Texas. Survey respondents were derived from a random convenience sample of women waiting for outpatient appointments. Participants were screened for having children under the age of 13 and/or childcare responsibilities for inclusion in the sample. Outcomes of interest included self-reported delayed or missed care, reasons for delayed or missed care, perceived difficulty in accessing childcare, prior methods for managing childcare during healthcare appointments, and prior experience with childcare centers.ResultsAmong the 336 respondents (96.7% response rate), 121 (36.0%) reported delaying or missing a mean 3.7 appointments/year. Among women with delayed or missed care, 54.5% reported childcare barriers as the primary reason for deferral of care, greater than transportation (33%) or insurance (25%) barriers. Respondents rated childcare access as more difficult than healthcare access. Delayed or missed care due to childcare was more common among White (68.8%) and Black (55.0%) women compared to Hispanic women (34.3%). Common methods of navigating childcare needs during scheduled appointments included bringing children to appointments (69.1%) and re-scheduling or missing the scheduled appointment (43.0%). 40.6% of patients reported leaving an appointment before completion due to childcare needs.ConclusionsChildcare needs are a leading barrier to healthcare among women accessing care in safety-net settings. Unmet childcare needs result in deferral of care, which may impact health outcomes. Childcare access is perceived as more challenging than healthcare access itself. Health system and policy interventions are needed to address childcare as a social determinant of health.

To What Extent Are Informal Healthcare Providers in Slums Linked to the Formal Health System in Providing Services in Sub-Sahara Africa? A 12-Year Scoping Review.

The contributions of informal providers to the urban health system and their linkage to the formal health system require more evidence. This paper highlights the collaborations that exist between informal providers and the formal health system and examines how these collaborations have contributed to strengthening urban health systems in sub-Sahara Africa. The study is based on a scoping review of literature that was published from 2011 to 2023 with a focus on slums in sub-Sahara Africa. Electronic search for articles was performed in Google, Google Scholar, PubMed, African Journal Online (AJOL), Directory of Open Access Journals (DOAJ), ScienceDirect, Web of Science, Hinari, ResearchGate, and yippy.com. Data extraction was done using the WHO health systems building blocks. The review identified 26 publications that referred to collaborations between informal providers and formal health systems in healthcare delivery. The collaboration is manifested through formal health providers registering and standardizing the practice of informal health providers. They also participate in training informal providers and providing free medical commodities for them. Additionally, there were numerous instances of client referrals, either from informal to formal providers or from formal to informal providers. However, the review also indicates that these collaborations are unformalized, unsystematic, and largely undocumented. This undermines the potential contributions of informal providers to the urban health system.
