A mixed-methods descriptive study on the role of continuous quality improvement in rural surgical and obstetrical stability: Considering enablers, challenges and impact.

INTRODUCTION: The Rural Surgical Obstetrical Networks (RSON) initiative in BC was developed to stabilize and grow low volume rural surgical and obstetrical services. One of the wrap-around supportive interventions was funding for Continuous Quality Improvement (CQI) initiatives, done through a local provider-driven lens. This paper reviews mixed-methods findings on providers' experiences with CQI and the implications for service stability. BACKGROUND: Small, rural hospitals face barriers in implementing quality improvement initiatives due primarily to lack of resource capacity and the need to prioritize clinical care when allocating limited health human resources. Given this, funding and resources for CQI were key enablers of the RSON initiative and seen as an essential part of a response to assuaging concerns of specialists at higher volume sites regarding quality in lower volume settings. METHODS: Data were derived from two datasets: in-depth, qualitative interviews with rural health care providers and administrators over the course of the RSON initiative and through a survey administered at RSON sites in 2023. FINDINGS: Qualitative findings revealed participants' perceptions of the value of CQI (including developing expanded skillsets and improved team function and culture), enablers (the organizational infrastructure for CQI projects), challenges in implementation (complications in protecting/prioritizing CQI time and difficulty with staff engagement) and the importance of local leadership. Survey findings showed high ratings for elements of team function that relate directly to CQI (team process and relationships). CONCLUSION: Attention to effective mechanisms of CQI through a rural lens is essential to ensure that initiatives meet the contextual realities of low-volume sites. Instituting pathways for locally-driven quality improvement initiatives enhances team function at rural hospitals through creating opportunities for trust building and goal setting, improving communication and increasing individual and team-wide motivation to improve patient care.

Rural patients' experiences with anesthesia and surgical consultations in British Columbia: A survey-based comparison between virtual and in-person modalities.

Introduction: Rural patients face barriers to accessing surgical care and often need to travel long distance for pre- or post-surgical consultations. Although adaptation to the COVID-19 pandemic has demonstrated the efficacy of virtual care, there is minimal data available to evaluate patient satisfaction with this modality and consequent health service utilization if virtual services are not available. Methods: An online survey was conducted with participants living in rural British Columbia, Canada who had undergone surgery within 12 months of data collection and had either virtual or face-to-face pre- or post-surgical consultations. It was supplemented by an in-person survey administered in two rural sites to all patients who had a virtual visit prior to undergoing procedural care. A ten-point scale was used to assess satisfaction. Quantitative and qualitative data were collected and analyzed. Results: Findings from the province-wide survey (n = 163) revealed no significant differences in average satisfaction ratings between people with in-person and virtual surgical consultations (8.03 versus 8.38, p = 0.26). However, most participants indicated that virtual appointments saved them time traveling, energy, and money and made them less dependent on others, accruing significant social benefit.In the community-focused sample (n = 71), 38% said they would not have had the procedure without a virtual visit option and 21% said that they would have delayed the procedure. Virtual consultations saved patients an average of 9 h (range 1-90). Participants traveled an average of 427 kilometers round trip to have the procedures. Conclusion: Findings reveal costs and time saved in accessing care due to the introduction of pre- and post-operative virtual care visits, and further investments in virtual care are warranted. This will contribute to promoting equitable access to healthcare for rural residents.

Optimizing rural healthcare through improved team function: a case study of the Rural Surgical Obstetrical Networks programme.

We explored enablers and mechanisms of optimal team function within rural hospital teams, and the impact of these factors on health service sustainability in British Columbia. The data were drawn from interviews and focus groups with healthcare providers and administrators (n = 169) who participated in the Rural Surgical Obstetrical Networks (RSON) initiative to support low-volume rural surgical and obstetrical services in British Columbia, Canada. The 5-year programme (2018-2022) provided evidence-based system interventions across eight rural sites with the objective of providing sustainable, quality health services to meet population needs. To explore the impact of RSON interventions on local team function, we performed a scoping review, to assess the current literature surrounding enablers of effective rural hospital teamwork. Through inductive thematic analysis of interview data, we identified five enablers of good team function at RSON sites, including emphasis on local leadership, shared direction, commitment to sustainability, respect and solidarity among colleagues, and meaningful communication. The RSON project led to a shift in team culture in participating sites, improved team function, and contributed to improved clinical processes and patient outcomes. The findings have implications for rural health policy and practice in British Columbia and other jurisdictions with similar health service delivery models and geographic contexts.

Perinatal Outcomes at Rural Hospitals That Participated in the Rural Surgical and Obstetrical Networks (RSON) of British Columbia (2016-2021).

BACKGROUND: The goal of the Rural Surgical and Obstetrical Networks (RSON) of British Columbia was to support safe and appropriate surgery, operative birth, and perinatal care closer to home for rural communities. Family physicians with enhanced obstetrical and/or surgical skills provide cesarean delivery and family practice anesthetists manage anesthesia for labour pain and operative births at RSON-supported hospitals, with the involvement of a local specialist at one site. OBJECTIVES: The objectives of the study were to: (1) compare perinatal outcomes at hospitals participating in the RSON initiative with outcomes at referral hospitals and (2) examine temporal changes in the proportion of childbearing people who resided in RSON communities and gave birth locally. METHODS: Poisson regression analysis was used to model the effect of hospital type (RSON vs. referral) on perinatal outcomes. We restricted the analysis to singleton births and controlled for differences in maternal characteristics, obstetric history, and pregnancy complications. RESULTS: Childbearing people who gave birth at RSON-supported hospitals (n = 3498) had a 10% lower incidence of adverse maternal-newborn outcomes compared to those who gave birth at referral hospitals (n = 14 772), after controlling for referral bias. We found a small increase (3.2 %) in the proportion of local births over the study period. CONCLUSION: Findings provide evidence that childbearing people can safely give birth at smaller rural hospitals in British Columbia and that investments in rural hospitals contribute to service stability. Stabilizing local birth services in rural communities benefits the whole region because it reduces surgical overload in regional referral centres.

System interventions to support rural access to maternity care: an analysis of the rural surgical obstetrical networks program.

BACKGROUND: The Rural Surgical Obstetrical Networks (RSON) project was developed in response to the persistent attrition of rural maternity services across Canada over the past two decades. While other research has demonstrated the adverse health and psychosocial consequences of losing local maternity services, this paper explores the impact of a program designed to increase the sustainability of rural services themselves, through the funding of four "pillars": increased scope and volume, clinical coaching, continuous quality improvement (CQI) and remote presence technology. METHODS: We conducted in-depth, qualitative research interviews with rural health care providers and administrators in eight rural communities across British Columbia to understand the impact of the RSON program on maternity services. Researchers used thematic analysis to generate common themes across the dataset and interpret findings. FINDINGS: Participants articulated six themes regarding the sustainability of maternity care as actualized through the RSON project: safety and quality through quality improvement opportunities, improved access to care through increased surgical volume and OR backup, optimized team function through innovative models of care, improved infrastructure, local innovation surrounding workforce shortages, and locally tailored funding models. CONCLUSION: Rural maternity sites benefited from the funding offered through the RSON pillars, as demonstrated by larger volumes of local deliveries, nearly unanimous positive accounts of the interventions by health care providers, and evidence of staffing stability during the study time frame. As such, the interventions provided through the Rural Surgical Obstetrical Networks project as well as study findings on the common themes of sustainable maternity care should be considered when planning core rural health services funding schemes.

Case report: Asymptomatic renal arteriovenous fistula requiring endovascular embolization in a living donor transplanted kidney more than 15-years after last protocol biopsy.

Here we present the case of an HLA-identical living-donor kidney transplant recipient, who was incidentally found to have a large complex renal arteriovenous fistula (RAVF) in their transplanted kidney that had been present for nearly 6 years but was previously misinterpreted as being part of a collection of cysts. This patient had undergone 7 protocol biopsies of the transplanted kidney, the last of which had been performed approximately 16 years prior, representing the longest interval between most recent biopsy renal allograft to RAVF diagnosis in the literature date. This report reviews the etiology and principles of management for RAVF.

The differential impact of size mismatch in live versus deceased donor kidney transplant.

BACKGROUND: The impact of weight mismatch between donors and recipients (D-R) undergoing living-donor kidney transplant (LDKT) versus weight-matched deceased donor kidney transplant (DDKT) is not established. AIM: To determine whether absolute weight mismatch between D-R affects graft survival following LDKT and how this relates to graft outcomes with DDKT when D-R are weight matched. MATERIALS & METHODS: We used multivariable Cox proportional hazards models and the Scientific Registry of Transplant Recipients to determine the association of weight-mismatched D-R (>50 kg, 30-50 kg or 10-30 kg ((D < R); (D > R) and <10 kg (D = R)) with death-censored graft failure in US LDKT recipients from 2006 to 2017. We also explored outcomes relative to weight-matched DDKT and finally, the impact of combined D-R weight-sex mismatch. RESULTS: In LDKT, the risk of graft loss was highest in the setting of D < R (HR 1.28, 95% CI 1.05-1.56 for >50 kg difference relative to D = R); however, this was still lower risk than weight-matched DDKT. D-R sex and combined weight-sex mismatch were only important for male recipients (HR 1.47, 95% CI 1.27-1.71 for a male recipient >30 kg larger than their female donor, relative to weight-matched male donor-male recipient). This remained superior to weight-sex-matched DDKT however. CONCLUSION: D-R weight-sex mismatch is important in LDKT; however, graft survival remains superior to proceeding with matched DDKT. Optimizing D-R matching in LDKT could be facilitated through a national kidney-paired donation registry. LDKT weight-sex mismatch should not be deferred in favor of DDKT.

Fenretinide corrects the imbalance between omega-6 to omega-3 polyunsaturated fatty acids and inhibits macrophage inflammatory mediators via the ERK pathway.

We previously identified Fragile X-related protein 1 (FXR1) as an RNA-binding protein involved in the post-transcriptional control of TNF and other cytokines in macrophages. Macrophages derived from FXR1-KO mice overexpress several inflammatory cytokines including TNF. Recently, we showed that fenretinide (4HPR) is able to inhibit several inflammatory cytokines in the lungs of cystic fibrosis mice, which also have abnormal immune responses. Therefore, we hypothesized that 4HPR might also be able to downregulate excessive inflammation even in macrophages with ablated FXR1. Indeed, our results demonstrate that 4HPR inhibited the excessive production of inflammatory mediators, including TNF, IL-6, CCL2 and CCL-5 in LPS-stimulated FXR1-KO macrophages, by selectively inhibiting phosphorylation of ERK1/2, which is naturally more phosphorylated in FXR1-KO cells. We also found that LPS stimulation of FXR1-KO macrophages led to significantly higher ratio of arachidonic acid/docosahexaenoic acid than observed in FXR1-WT macrophages. Interestingly, treatment with 4HPR was associated with the normalization of arachidonic acid/docosahexaenoic acid ratio in macrophages, which we found to impact phosphorylation of ERK1/2. Overall, this study shows for the first time that 4HPR modulates inflammatory cytokine expression in macrophages by correcting a phospholipid-bound fatty acid imbalance that impacts the phosphorylation of ERK1/2.

Microscale solution isoelectric focusing as an effective strategy enabling containment of hemeoglobin-derived products for high-resolution gel-based analysis of the Plasmodium falciparum proteome.

The high hemeozoin (beta-hemeatin) content of Plasmodium falciparum lysates imposes severe limitations on the analysis of the malarial proteome, in particular compromising the loading capacities of two-dimensional gels. Here we report on the adaptation of a recently developed solution-phase isoelectric focusing-based fractionation technique as a prefractionation strategy for efficient containment of hemeoglobin-derived products and complexity reduction, to facilitate the high-resolution gel-based quantitative analysis of plasmodial lysates.
