Effect of race and sex on lupus diagnosis in primary care: A randomized factorial survey study

by Alyssa Howren, Quan L. Tran, Sadaf Sediqi, Saadiya Hawa, Douglas K. Owens, Eleni Linos, Titilola O. Falasinnu, Yashaar Chaichian, Julia F. Simard

Background

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune rheumatic disease whose epidemiology and clinical prognosis vary by race and sex. Observed disparities in SLE may be partly attributable to cognitive processes in clinical decision-making, which can influence diagnostic accuracy and clinical management. We aimed to examine variation in primary care physicians’ (PCP) diagnosis and management of SLE when all content of a clinical case is identical, apart from race and sex.

Methods

We distributed an online randomized factorial survey from 04/11/2024–06/10/2024 to PCPs across the US. Participants were presented with one of four possible SLE vignettes – Black female, White female, Black male, White male – for which all other clinical content was identical. Block randomization was used to randomly modify the race (Black/White) and sex (female/male) of the SLE “case”. Primary outcomes were correct text-based responses for SLE diagnosis at initial case presentation and after reviewing additional lab results. Secondary outcomes were participants’ review time and planned next steps (treatment, referral, tests) as a proxy for cognitive bias and certainty, respectively. We calculated descriptive statistics for all outcomes stratified by assigned randomized factor and used chi-square tests to evaluate between-group differences.

Results

1031 PCPs (42.7% women, mean age 52.1 ± 12.1 years) completed the case. At initial presentation, 63.9% of participants correctly identified SLE as a differential diagnosis. An initial diagnosis of SLE significantly differed by the race and sex of the case (p  Conclusion

A patient’s race and sex may influence diagnostic accuracy and clinical decision-making for SLE in primary care. The observed variation in diagnostic accuracy, which aligns with the descriptive epidemiology of SLE, highlights the need for targeted interventions to ensure equitable diagnostic processes.

Geriatric Models of Surgical Care: A Scoping Review

ABSTRACT

Aim

To synthesise literature on hospital-based geriatric models of care for older adults undergoing surgery, examining structures, team composition, governance and nursing contributions.

Design

Scoping review.

Methods

Following JBI methodology, two reviewers independently screened articles against eligibility criteria (Population: adults ≥ 65 years, Concept: multidisciplinary geriatric surgical care model; Context: acute hospital settings), with conflicts resolved by a third reviewer. Data were extracted and charted for descriptive synthesis.

Data Sources

Six databases (CINAHL, MEDLINE, Embase, Scopus, AgeLine, Cochrane Library) searched for studies published between January 2015 and February 2025.

Results

Of 2753 records identified, 81 studies were included. Models were commonly co-managed between surgical and geriatric teams, implemented at varying surgical pathway points. Orthopaedics represented 57% of studies. Geriatricians were involved in 90% of models; 38% included advanced practice nurses or specialist gerontological nurses. Comprehensive Geriatric Assessment was used in nearly half the studies, typically preoperatively. Considerable heterogeneity existed in model design, professional roles and care settings.

Conclusion

Integrated geriatric perioperative care is expanding globally but remains limited outside orthopaedics. Research should shift from improvement projects to rigorous implementation for sustainable transformation, including nurse-led models. Critical examination is needed of whether current outcomes address comprehensive needs of older surgical patients or primarily optimise hospital flow.

Implications for the Profession and/or Patient Care

Findings highlight opportunities to expand geriatric models beyond orthopaedics and enhance nursing roles, particularly advanced practice nurses, in delivering comprehensive perioperative care for older adults.

Impact

Addressed the gap in understanding how geriatric models of surgical care are operationalised. Identified underutilisation of nursing expertise and limited expansion beyond orthopaedics. Will impact service design, policy development and clinical implementation for older surgical patients.

Reporting Method

Adhered to PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines.

Investigating the effects of cannabinoids for the reduction of inflammation and sickle cell disease pain (CRISP); A protocol for a randomized double-blind placebo-controlled study

by Jordan Bellis, Lydia Monk, Ritika Jhawar, Galia Pollock, Angela Liu, Charleen Jacobs-McFarlane, Brittany McCrary, Jeffrey Glassberg, Susanna Curtis

Sickle Cell Disease (SCD) is a hemoglobinopathy affecting millions of people globally. Pain, both acute and chronic, affects over half of those living with SCD, but treatment of chronic pain is an ongoing challenge. While opioid treatments are widely used for chronic pain, it’s efficacy is limited, so alternatives must be explored. This protocol outlines a procedure for investigation of dronabinol, an FDA-approved synthetic tetrahydrocannabinol (THC), for the treatment of pain in patients living with SCD and chronic pain. The study is an 8-week, randomized, double-blind placebo-controlled study which aims to assess both the efficacy and safety of this opioid alternative to pain treatment. The study will also track biomarkers of inflammation as THC has demonstrated anti-inflammatory properties, and inflammation is a driver of SCD pain and disease severity. Results from this study have the potential to further clinical understanding of cannabinoids for pain management in Sickle Cell Disease treatment and spark new questions for research.

Breastfeeding and later depression and anxiety in mothers in Ireland: a 10-year prospective observational study

Por: McNestry · C. · OReilly · S. L. · Twomey · P. J. · Crowley · R. K. · Callanan · S. · Kasemiire · A. · Douglass · A. · Delahunt · A. · McAuliffe · F. M.
Objectives

Although breastfeeding is associated with lower postnatal depression and anxiety, limited research exists regarding long-term maternal mental health outcomes. This study examined the association between breastfeeding and depression and anxiety in women of later reproductive age (mid 30s to menopause).

Design

This was a 10-year prospective longitudinal cohort study. Self-reported questionnaires were used to collect lifetime breastfeeding behaviour at 10 years, and health history including depression, anxiety and medication use was collected at each study timepoint.

Setting

A tertiary level maternity hospital in Dublin, Ireland.

Participants

168 parous women from the ROLO Longitudinal Cohort with lifetime breastfeeding behaviour and health history data available at 10 years were included (22% of total cohort). Women currently pregnant or breastfeeding at 10-year follow-up were excluded.

Results

Mean (SD) age at study end was 42.4 (3.8) years. 72.6% (n=122) of women reported ever breastfeeding. Median lifetime exclusive breastfeeding was 5.5 weeks (IQR 35.8, range 0–190). 37.5% of women (n=63) breastfed for ≥12 months over their lifetime. 13.1% (n=22) reported depression or anxiety at 10 years, and 20.8% (n=35) reported depression or anxiety over the whole study period. Ever breastfeeding was associated with less depression and anxiety at 10 years (OR 0.34, 95% CI 0.12 to 0.94, p=0.04). Ever breastfeeding, longer exclusive breastfeeding and lifetime breastfeeding ≥12 months were associated with lower depression and anxiety over the whole study period (ever breastfeeding OR 0.4, p=0.03; exclusive breastfeeding OR 0.98/week, p=0.03; lifetime breastfeeding ≥12 months OR 0.38, p=0.04).

Conclusion

There may be a protective association between breastfeeding and self-reported depression and anxiety. Further studies are required to confirm the findings.

The Kids Pain Collaborative: A Hybrid Type 3 Implementation Effectiveness Study Transforming Paediatric Pain Care in the Emergency Department

ABSTRACT

Aim

To evaluate the impact of a participatory, action-oriented implementation study, guided by the integrated Promoting Action on Research Implementation in Health Services framework, for optimising pain care processes in a tertiary paediatric emergency department.

Design

Hybrid type 3 implementation effectiveness.

Methods

A collaborative appraisal of the context and culture of pain care informed two interdependent action cycles: Enabling nurse-initiated analgesia and involving families in pain care. The Kids Pain Collaborative, an authentic clinical–academic partnership, was central to facilitating successful implementation. Summative evaluation explored the impact of implementation on processes of pain care using an interrupted time series analysis and emotional touchpoint interviews with families.

Results

Staff achieved clinically important and sustained improvements in the rate of nurse-initiated analgesia and pain assessment. Family involvement in pain care shifted from task-orientated practices towards more person-centred ways of working and decision-making. As capacity for collective leadership developed, frontline staff found ways to integrate the KPC approach into ED systems to lead pain care innovation beyond the life of the research project.

Conclusions

The Kids Pain Collaborative, as the overarching implementation strategy, created a practitioner-led coalition for change. Successful implementation was facilitated by working with four interdependent principles: Collaborative and authentic engagement; enabling context for cultural transformation; creating safe spaces for critical reflection and workplace learning; and embedding sustainable practice change.

Impact

A multi-level model of internal–external facilitation enabled sustained improvement in pain care practice. An embedded researcher was pivotal in this process.

Patient Contribution

Authentic engagement of clinicians and families was pivotal in transforming systems of pain care and enabling a culture where "it is not ok for children to wait in pain"

Implications for Practice

The principles underpinning the Kids Pain Collaborative are transferable to other emergency department and acute care contexts.

Integration of precision medicine into routine cancer care--protocol for the Precision Care Initiative: a research programme of effectiveness-implementation hybrid trials

Por: Liang · S. · McKay · S. · Lin · F. · Zaheed · M. · Morrow · A. · Douglas · B. · Chan · J. · Monaghan · H. · Chan · P. · Kennedy · E. · Tyedmers · E. · Walker · S. · Leaney · K. · Napier · C. E. · Middleton · S. · Butow · P. · Williams · R. · Parkinson · B. · Ballinger · M. L. · Tucker · K. · G
Introduction

Genomic diagnostics have accelerated therapeutic and preventative breakthroughs in oncology and cancer genetics. Despite increased access, the implementation of genomics-based care faces serious fragmentation and scalability issues due to a lack of system support. The Precision Care Initiative aims to develop a novel and scalable Precision Care Clinic (PCC). It is designed to coordinate precision medicine in oncology and streamline decision support for referring oncologists and geneticists. The PCC will enhance quality of care through multifaceted, patient-centred communication. It will also improve translational capacity by integrating team expertise in precision oncology, implementation science, clinical informatics, cancer genetics, health economics and patient-reported measures.

Methods and analysis

This programme uses a type I and type II hybrid effectiveness-implementation trial design sequentially. The complex clinical intervention is precision oncology—matching the targeted treatment or risk management strategy to the right patient, based on their genomic, cancer staging, environmental, lifestyle and biological characteristics, etc. The service intervention is the PCC, providing centralised multidisciplinary review to facilitate shared decision-making with clinicians for the provision of optimal precision oncology care for their patients. The implementation intervention is the co-designed implementation platform—applying evidence-based implementation approaches and Learning Health System principles to enhance feasibility and sustainability. All adult patients across Australia referred to the PCC (n=est. 100–150/year), and healthcare professional interest holders involved in the delivery of precision oncology services, are eligible to participate. Over the study course, phase I involves using a mixed-methods approach to inform iterative co-design and pilot testing of the first PCC with an accompanying implementation platform, and a suite of outcome measures to assess effectiveness; phase II (hybrid type I) includes the implementation of the PCC and evaluation of the outcome measures designed in phase I; phase III (hybrid type II) involves a co-design of local adaptations and testing the effectiveness of the PCC model nationally.

Ethics and dissemination

The study received ethical approval from the St Vincent’s Hospital Human Research Ethics Committee (2023/ETH00373). Study results will be presented at relevant conferences and published in peer-reviewed journals.

Tirzepatide for the treatment of adults living with concurrent type 1 diabetes and overweight or obesity (TZP-T1D): a double-blind, placebo-matched randomised controlled trial protocol

Por: Purcell · A. R. · Rodrigo · N. · Longfield · M. S. G. · Glastras · S. J.
Introduction

The increasing prevalence of overweight and obesity among individuals with type 1 diabetes (T1D) complicates glycaemic management and escalates insulin resistance, necessitating innovative therapeutic strategies. Tirzepatide, a dual agonist for glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptors, shows promise in managing weight and glycaemic control in type 2 diabetes but is unexplored in the context of T1D. This double-blind, placebo-controlled randomised trial will evaluate the efficacy of tirzepatide in adults with T1D and overweight/obesity over 32 weeks.

Methods and analysis

60 participants (aged 18–70 years) with a body mass index ≥27 kg/m2 and HbA1c≤10% will be randomised 1:1 to receive either tirzepatide or a placebo, alongside standard insulin therapy. The primary outcome is the change in body weight (%). Secondary measures include change in HbA1c (%), proportion of body weight lost (>5%, >10%, >15% and >20%), changes in insulin dosage, time in range by continuous glucose monitoring (CGM) criteria and severity of comorbidities. Compliance, adverse events and medication interactions will be closely monitored, with adjustments made for tolerability. Patient-reported outcomes and experiences will be measured to capture the benefits of glycaemic management, weight management and quality of life. To compare the means of body weight reduction (%) between the tirzepatide and control groups, an independent samples t-test will be employed under the assumption that data are normally distributed. Secondary outcome measures will be analysed by Student’s t-test. All data will be reported as group means with confidence intervals, with default statistical significance assumed at p

Are we closing the gender gap in academic oncology? An observational study of gender disparities in participant engagement at the ASCO 2024 annual meeting

Por: Puhr · H. C. · Cammarota · A. · Ettaieb · M. · Flierman · I. · Gisinger · T. · Glas · A. · Guven · D. C. · Siebenhüner · A. · Steindl · A. · Szydlik · V. · Valpione · S. · Yip · M. · van Laarhoven · H. W. M.
Objective

Despite global efforts, gender disparities in oncology may persist. Understanding these disparities within the context of major conferences can inform strategies to promote gender inclusiveness in the field. This study evaluates the participation of women and men at the American Society of Clinical Oncology (ASCO) 2024 congress, focusing on chairs, speakers and audience questioners.

Design

Observational study.

Setting

152 recorded sessions of the ASCO 2024 annual meeting, one of the largest conferences in the field of oncology, available on the ASCO website.

Participants

Individuals serving as chairs, speakers and audience members who asked questions.

Primary and secondary outcome measures

In this observational study, gender for chairs, speakers and audience questioners across 152 sessions of the ASCO 2024 congress was assessed by two independent reviewers using audio and video recordings. Speaking times for questions and responses were also evaluated. Statistical analyses, including 2 and unpaired t-tests, were conducted to analyse the data.

Results

Women were well represented as chairs (n=124) and speakers (n=402) in 66% and 95% of sessions, respectively. However, only 21% of questions from the audience were posed by women, while 37% of questions were asked by men and 42% online or by chairs/speakers. Women were more likely to pose questions when the sessions were chaired by women (71% vs 53%; p=0.047). There were no statistically significant gender disparities concerning speaking time (questions: p=0.30; responses: 0.53). The response dynamics indicated a pattern of gender homogeneity, with individuals more frequently responding to questions from their own gender.

Conclusions

While the balanced representation of women in leadership roles at the ASCO 2024 congress reflects positive development in gender equality, disparities in active participation persist. These findings underscore the need for strategies that not only promote women in visible roles but also foster an environment that supports their active engagement in scientific discussions.

Introduction

Preterm infants, particularly those born before 29 weeks of gestation, are at increased risk of developing bronchopulmonary dysplasia (BPD) and other complications of prematurity. Substantial evidence suggests that respiratory tract colonisation with Ureaplasma species significantly contributes to pulmonary inflammation, impaired lung function and subsequent lung disease especially in very immature infants. Moreover, Ureaplasma exposure has been implicated in the pathogenesis of other inflammation-related sequelae of prematurity. Although representing a potentially actionable risk factor for adverse short-term and long-term neonatal outcome, controversies on Ureaplasma-associated morbidity remain and recommendations for screening practices in preterm infants are missing. The NEO-CONSCIOUS (Neonatal Colonisation and Infection with Ureaplasma in very immature preterm infants born Ureaplasma colonisation and infection in very preterm infants at high risk of adverse outcome, the extent of potentially accompanying inflammation and the impact on short-term and long-term morbidity.

Methods and analysis

This is a prospective observational multicentre study being conducted in level III neonatal intensive care units in Germany and Austria. In total, 400 infants born before 29 weeks of gestation are screened for Ureaplasma colonisation immediately after birth. In addition, biomarkers of systemic inflammation are determined on day 1 and day 28. The study infants are followed up until discharge and at 2 years corrected age. The primary outcome BPD and/or death is assessed at 36 weeks postmenstrual age. Secondary outcomes include systemic inflammation, secondary infections, intraventricular haemorrhage, periventricular leukomalacia, necrotising enterocolitis, retinopathy of prematurity and neurodevelopmental outcome at 24 months corrected age.

Ethics and dissemination

The study has been approved by the ethics committees in Würzburg and Leipzig and the local ethics committees of all participating centres. Results will be disseminated through peer-reviewed international publications and conferences. The study is registered with the German Clinical Trials Register, ID DRKS00033001.

Exploring tools and measures for evaluating the quality of paid disability support for adults: a scoping review protocol

Por: Topping · M. · Douglas · J. · Winkler · D.
Introduction

The quality of paid disability support services has significant implications for the autonomy, well-being and community participation of adults with disability. However, variability in service provision and evaluation persists. Despite the growing public investment and focus on improving support quality, there appears to remain a lack of comprehensive tools and measures to evaluate the quality of paid disability support. This scoping review aims to systematically identify and map the existing tools and measures used to evaluate the quality of paid disability support for adults with disability.

Methods and analysis

This scoping review will be conducted following the methodology outlined by Arksey and O’Malley, enhancements proposed by Levac et al and the Joanna Briggs Institute along with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis: Extension for Scoping Reviews guidelines. The research question guiding the review is: ‘What existing tools and measures are available to evaluate the quality of paid disability support services?’ Comprehensive searches will be conducted in MEDLINE, PsycINFO, Embase, CINAHL and Scopus to identify peer-reviewed articles published in English since 2014. Supplementary grey literature searches will also be conducted, alongside an online survey to obtain stakeholder input. Articles or grey literature sources that report on tools or measures for evaluating paid disability support for adults (aged 18–65 years) with disability will be included. Data extraction will focus on study characteristics, participant demographics and the characteristics of the quality of support measurement tools. A narrative synthesis will be used to present the findings.

Ethics and dissemination

Ethical approval will be obtained for the online stakeholder survey component of the review. No ethical approval is required for the scoping review of the literature. The results will be disseminated through peer-reviewed publications, conference presentations and accessible formats to ensure a wide audience is reached, including researchers, policymakers and disability service providers.

Understanding the needs and experiences of young cancer patients, caregivers and healthcare professionals in the UK following childhood fertility tissue preservation (FTP): a qualitative study informed by patient and public involvement and engagement

Por: Mottram · R. · Feltbower · R. · Jones · G. L. · Gelcich · S. · McLean · K. · Kelly · C. · Glaser · A.
Background

Childhood cancer treatment can cause subfertility in adulthood. Ovarian or testicular tissue preservation is a rapidly evolving field with significant potential benefits. However, the establishment of patient-centred reproductive survivorship pathways remains a challenge in clinical settings due to a lack of robust evidence to inform its development. Patient and public involvement and engagement (PPIE) consultation may help ensure that future studies align with patient needs and that tailored survivorship care pathways are developed for young people with preserved fertility tissue.

Aim

This PPIE consultation aimed to identify priority areas for future research that would support the development of a tailored survivorship care pathway for childhood cancer survivors who have preserved tissue for future fertility.

Methods

Recruitment occurred through national networks, including collaborations with advocacy groups such as Candlelighters and clinical networks. Data were collected via telephone or online unstructured interviews, with some supplementary email exchanges. Thematic analysis was used to identify emergent themes. The Guidance for Reporting Involvement of Patients and the Public (GRIPP)-2 guidelines were used to help guide PPIE.

Setting

An online focus group and/or a one-to-one interview with e-mail interactions.

Participants

In total, 12 unique participants took part in a focus group and/or interview. Participants included parents of children who had stored tissue, young adult cancer survivors with stored tissue and five clinicians from the leading National Health Service (NHS) centres in the UK.

Results

Six key themes emerged that highlighted unmet needs and priority areas for research: (1) Lack of communication and information; (2) unmet needs in follow-up care; (3) emotional impact and psychological support; (4) importance of patient and parental involvement; (5) desire for information and education; and (6) long-term concerns and support. Parents, young adults and healthcare clinicians found talking about fertility issues difficult. They noted that consistency of care, education resources and access to emotional support were important areas where improvements could be made. We used thematic analysis to help identify patterns in the data, and we used the Guidance for Reporting Involvement of Patients and the Public (GRIPP)-2 reporting guidelines for PPIE work.

Conclusions

PPIE provided valuable insights into the experiences of childhood cancer survivors with preserved fertility tissue, their parents and clinicians, highlighting priority areas to guide future research and ensure it addresses the concerns of care recipients. Our findings suggest that childhood cancer survivors who preserve tissue for future fertility need personalised follow-up care with information and psychological support. A larger sample of participants, studied using a qualitative research design, is needed to capture the full range of experiences, needs and preferences and to ensure that care is inclusive and relevant to the wider population.

Smoking cessation in people with multiple sclerosis: qualitative study on the current practices and barriers for delivering assistance from the perspective of healthcare professionals in Germany

Por: Keller · A. M. · Marck · C. H. · Kotz · D. · von Glasenapp · B. · Heesen · C. · Riemann-Lorenz · K.
Objectives

Smoking is a well-established risk factor that exacerbates multiple sclerosis (MS) progression and increases disease activity. Smoking cessation promotion practices of MS clinicians are not meeting the needs of people with MS (pwMS). This study aimed to explore the current practices and barriers faced by MS clinicians in Germany.

Design

A qualitative study design, using semi-structured interviews and thematic analysis.

Setting

Interviews with participants were held online, via telephone or face-to-face at our institute in Hamburg, Germany.

Participants

We recruited eight neurologists and four MS nurses from hospitals, neurology practices and rehabilitation facilities in Germany via purposive and snowball sampling.

Results

We identified 27 codes across four themes: (1) knowledge: the 12 participants demonstrated a satisfactory general knowledge of the negative impacts of smoking on MS (2) current practice: significant variability was reported in the current practices, with some clinicians providing detailed advice while others merely assessing smoking status without further advice or assistance. (3) Barriers: key barriers identified included limited consultation time, perceived lack of patient motivation and insufficient availability of resources, like information material, for effective smoking cessation support. (4) Needs and wishes: participants wished for specific smoking cessation courses to which they could refer patients, as well as information material to use during patient counselling.

Conclusion

The study reveals considerable gaps in the consistency and comprehensiveness of smoking cessation support provided by MS clinicians in Germany. Addressing these gaps through targeted interventions, and improving the availability of information materials could enhance smoking cessation promotion for pwMS.

Cognitive deficits in treatment-resistant depression: protocol for a systematic review and meta-analysis

Por: Ronold · E. H. · Jensen · D. · Thorsen · A. L. L. · Raudeberg · R. · Oltedal · L. · Hammar · A. · Hirnstein · M. · Douglas · K. · Porter · R. · Kiebs · M.
Introduction

Major depressive disorder (MDD) is a major global healthcare challenge. This is, in part, due to the lack of treatment response and chronic course of MDD. Such a course of illness is often termed treatment-resistant depression (TRD) and is seen in over one-third of people with MDD. Reasons for treatment resistance are not well established, nor is the definition of TRD. Duration and severity of depression, however, are associated with TRD and are also associated with cognitive deficits. Thus, TRD could be particularly prone to cognitive deficits and at heightened risk for neuroprogression. While the cognitive profile of MDD has been investigated in several systematic reviews, no systematic review of cognition in TRD exists to date. The present study will fill this gap in the literature. It is expected that TRD will show more severe cognitive deficits than generally reported in MDD and deficits in all cognitive functions are expected.

Methods and Analysis

A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines will be performed of the databases Embase, Pubmed/MEDLINE, PsychINFO and Cochrane including peer-reviewed studies on humans using standardised cognitive tests. Pilot searching was performed in January 2025 and the full search will be commenced in June 2025, with additional searches following completion. Where sufficient data are reported, a meta-analysis comparing deficits in TRD with MDD and healthy control participants will be performed; alternatively, effects based on norms will be calculated. Meta-regression, subgroup and sensitivity analyses will be conducted to explore moderators that are sufficiently reported in the literature. The quality of studies will be assessed by the Newcastle-Ottawa Scale.

Ethics and dissemination

Ethical approval is not necessary to perform the study, and results will be presented at a suitable conference and published in a peer-reviewed journal.

Worse Nursing-Sensitive Indicators in Black-Serving Hospitals

imageBackground In hospitals that serve disproportionately patients of Black race, here termed Black-serving hospitals (BSH), nurse staffing is worse, mortality rates are higher, and nursing-sensitive indicators may be worse than in other hospitals, but this evidence has not been compiled. Objective The study objective was to examine whether nursing-sensitive indicators, which measure changes in patient health status directly affected by nursing care, differ in hospitals where Black patients predominantly access their care, as compared to other hospitals. Methods To fulfill the objective, a cross-sectional design using publicly available 2019 to 2022 Hospital Compare, 2019 Medicare Provider Analysis and Review (MEDPAR), and case mix index (CMI) file databases were used. Four nursing-sensitive indicators were evaluated: pressure ulcer, postoperative sepsis, perioperative pulmonary embolus/deep vein thrombosis, and death rate among surgical inpatients with serious treatable complications (“failure to rescue”) in hospitals classified into high, medium, and low BSHs according to the percentage of patients of Black race in the MEDPAR data. Mean outcome differences across BSH categories were assessed through analyses of variance and regression models, which controlled for hospital CMI. Results The 3,101 hospitals were predominantly urban nonteaching hospitals in metropolitan areas. Although 12% of hospitals had Magnet designation, BSHs were disproportionately Magnet (14%). The outcome rates were 0.59 for pressure ulcers, 3.38 for perioperative pulmonary embolus/deep vein thrombosis, 143.58 for failure to rescue, and 4.12 for sepsis. Rates were significantly higher for pressure ulcers, perioperative pulmonary embolus/deep vein thrombosis, and sepsis in high BSHs. The mean failure to rescue rate was similar across low-to-high BSHs and did not show significant differences. These results were unchanged in models adjusting for CMI. Discussion The evidence suggests that several nursing-sensitive indicators are worse in high BSHs. Research linking nursing-sensitive indicators to nursing resources such as staffing is needed to explicate the mechanism underlying these findings. Poorer nursing-sensitive indicators in combination with poorer nurse staffing in high BSHs presents a priority for policy and management intervention.

Poorer Nurse Staffing in Black-Serving Hospitals

imageBackground Patients in hospitals that serve disproportionately patients of Black race have worse outcomes than patients in other hospitals, but the modifiable nursing factors that may contribute to such disparities have not been explored. Objective The study objective was to examine whether nurse staffing differs in hospitals that serve predominantly patients of Black race (Black-serving hospitals) as compared to other hospitals. Methods A cross-sectional correlational design using a nurse survey in a national hospital sample was used to fulfill the study objective. Nurse staffing was measured as the maximum number of patients cared for on the last shift from the 2015 annual registered nurse survey conducted in National Database of Nursing Quality Indicators hospitals. Hospitals were classified into subgroups of low, medium, and high percentages of patients of Black race using the 2019 Medicare Provider Analysis and Review database. Results In survey data from 179,336 registered nurses in 574 hospitals, nurse staffing was significantly worse in high-Black-serving hospitals as compared to medium- and low-Black-serving hospitals. In Poisson regression models that adjusted for nursing unit type and hospital characteristics, nurses in high-Black-serving hospitals and medium-Black-serving hospitals had more patients-per-nurse than did nurses in low-Black-serving hospitals. Discussion Small, statistically significant differences in nurse staffing that are worse in hospitals where Black patients disproportionately access their care were found using nurse survey data accounting for nursing unit type. The poorer nurse staffing in Black-serving hospitals may compromise the care and outcomes of the seven in 10 hospitalized Black older adults who receive care in Black-serving hospitals. The consequences for patient outcome disparities of poorer nurse staffing in Black-serving hospitals deserve investigation. Policies to increase nurse staffing in hospitals serving a higher proportion of patients of Black race are needed to contribute to efforts to reduce health disparities.
