RESUMO

OBJECTIVES: This study sought to evaluate performance indicators to assist a static-based 9-1-1 agency in defining its response efficiency. METHODS: Initial assessment of three metrics-unit hour utilization (UHU), fractile response intervals, and level 0 frequency (occurrence when no ambulances are available to respond)-suggested the agency's response over its four coverage zones was inefficient, so an operational change was implemented: an ambulance was relocated from one service area to another to improve the overall response productivity. A 2-year retrospective analysis was performed to determine the impact ambulance relocation had on the three targeted measurements. RESULTS: The operational change resulted in a statistically significant change in unit hour utilization, a non-significant increase in fractile response intervals, and a statistically significant reduction in level 0 frequency from pre- to post-operational change times. CONCLUSIONS: These findings suggest a way to evaluate the efficiency of static-based ambulance deployment and potentially identify strategies for redeployment.

RESUMO

AIMS: The kaupapa of the Caring for Australians and New Zealanders with Kidney Impairment (CARI) Clinical practice guidelines for management of chronic kidney disease for Maori in Aotearoa New Zealand is to provide whanau-centred and evidence-based recommendations to healthcare systems, healthcare providers and healthcare workers. The guidelines include screening, identification, management and system-level responses to chronic kidney disease (CKD) to deliver best practice care to Maori affected by CKD across community, primary and secondary services. METHODS: The guidelines are funded by the Ministry of Health - Manatu Hauora and are written by a panel of Maori and non-Maori clinicians and literacy experts across Aotearoa New Zealand from Kaupapa Maori organisations, general practice and nephrology units using standardised methods. The guidelines methodology included consultation with whanau Maori with lived experience of CKD and primary and secondary care practitioners. Additional guideline development would be required to inform management of CKD for non-Maori in Aotearoa New Zealand. RESULTS: The guidelines provide recommendations about equity, governance and accountability, cultural safety, case management, information systems, social determinants of equity and wellbeing and screening. CONCLUSIONS: Recommendations to health services for Maori with CKD are based on giving effect to Te Tiriti o Waitangi and best practice care to prevent CKD, delaying its progression, treating kidney failure through timely transplantation, delivering in community and providing high-quality symptom management.

RESUMO

OBJECTIVES: Indigenous people experience higher rates of kidney failure than do non-Indigenous Peoples. However, compared to Indigenous patients, health care systems deliver kidney transplantation to non-Indigenous patients at a substantially higher rate and more frequently as the first treatment of kidney failure. Indigenous Maori patients in Aotearoa New Zealand report numerous barriers to kidney transplantation. We explore the perspectives of clinicians as stakeholders in the delivery of kidney transplantation. METHODS: In 2021/2022 we conducted in-depth qualitative interviews with key stakeholder clinicians within kidney transplantation services in Aotearoa New Zealand, asking them about the issues for Maori patients. We used thematic analysis informed by critical theory to identify key findings and used structural coding to categorize the themes at the level of society, health system, and health services. RESULTS: We interviewed 18 clinicians (nine nephrologists, including two transplant nephrologists, and nine nurses, including six transplant coordinators). We identified nine themes from stakeholders related to delivery of kidney transplantation services to Maori patients and whanau (family), categorized according to three main levels: Firstly, at the level of society (the impact of colonization and distrust). Secondly, the health care system (failure to prevent and manage kidney disease, health care model delivers inequitable outcomes, and inadequate Maori health professional workforce). Thirdly, health care services (transplantation reliant on patient and family resources, complex assessment causes untimely delays, clinical criteria for transplantation, and lack of clinician ability to effect change). CONCLUSIONS: Delivery of kidney transplantation to Indigenous Peoples is impacted at the level of society, health care system, and health care service. To address inequities, a broad approach that addresses each of these levels is required.

RESUMO

BACKGROUND: People treated with home dialysis report social and emotional isolation, fear of catastrophic events and concern about being a burden. There is a paucity of research exploring psychological well-being among consumers dialysing at home. We aimed to explore the psychological health issues related to home dialysis, and how these issues may impact on sustaining home-based treatment. METHODS: We conducted a qualitative interview study with 36 consumers. We included patients with experience of home dialysis and caregivers. Thirteen participants had experienced peritoneal dialysis, seven home haemodialysis, seven had experienced both and nine caregivers. Data were analysed inductively to generate themes and a conceptual framework. RESULTS: We identified four themes and subthemes: overwhelming isolation and disconnection (devastating isolation of home dialysis; abandoned from support; escalating anxiety; compounding impact of feeling like a burden); importance of support systems (impact on relationships; need for emotional support; reassurance through shared experiences; valuing trustworthy and committed clinicians); burden of distress (individualised feelings of low mood; grappling with stigma surrounding diagnosis; contemplating treatment withdrawal and suicide); seeking mental health support (normalising mental health support as a distinct entity in dialysis care; overcoming barriers to seeking mental health support; additional tools for mental health support and connection). CONCLUSION: Consumers may experience intense psychological distress during home-based dialysis care. Increasing clinician and health services literacy about the management of psychological impacts of home-based dialysis may improve consumer safety, quality of life and sustainability of home treatment.

RESUMO

INTRODUCTION: A majority of US medical schools have incorporated faculty coach-supported educational portfolios into the curriculum. Existing research describes coach professional development, competencies, and program perceptions. However, limited research exists on how programs address coach professional development needs. Our sequential objectives were to (1) explore faculty coach professional development experiences within medical student coaching programs and (2) develop a preliminary framework for medical faculty coach professional development. METHODS: Faculty portfolio coaches who completed 4 years of a longitudinal coaching program were recruited to complete a semi-structured exit interview. Interviews were transcribed using detailed transcription. Two analysts inductively generated a codebook of parent and child codes to identify themes. They compared themes to the professional development model proposed by O'Sullivan and Irby. RESULTS: Of the 25 eligible coaches, 15 completed the interview. Our team organized themes into two broad domains paralleling the established model: program-specific professional development and career-relevant professional development. Four program-specific professional development themes emerged: doing; modeling; relating; and hosting. Three career-relevant professional development themes emerged: advancement; meaning; and understanding. We then applied themes within each domain to propose strategies to optimize coach professional development and develop a framework modeled after O'Sullivan and Irby. DISCUSSION: To our knowledge, we propose the first portfolio coach-informed framework for professional development. Our work builds on established standards, expert opinion, and research responsible for portfolio coach professional development and competencies. Allied health institutions with portfolio coaching programs can apply the framework for professional development innovation.

RESUMO

BACKGROUND: Reported experiences of racism in Aotearoa New Zealand are consistently associated with negative measures of health, self-rated health, life satisfaction, and reduced access to high-quality healthcare with subsequent poor health outcomes. In this paper, we report on perceptions and experiences of prejudice and racism by Indigenous Maori with kidney disease and their family members and donors who took part in a wider study about experiences of kidney transplantation. METHODS: We conducted semi-structured interviews with 40 Maori between September and December 2020. Participants included those with kidney disease who had considered, were being worked up for, or who had already received a kidney transplant as well as family members and potential or previous donors. We examined the data for experiences of racism using a theoretical framework for racism on three levels: institutionalised racism, personally mediated racism, and internalised racism. RESULTS: We identified subthemes at each level of racism: institutional (excluded and devalued by health system; disease stigmatization; discriminatory body weight criteria, lack of power), personally mediated (experiencing racial profiling; explicit racism), and internalized racism (shame and unworthiness to receive a transplant). CONCLUSIONS: The wide-reaching experiences and perceptions of racism described by participants with kidney disease and their families in this research point to an unfair health system and suggest that racism may be contributing to kidney transplantation inequity in Aotearoa New Zealand. Addressing racism at all levels is imperative if we are to address inequitable outcomes for Maori requiring kidney transplantation.

RESUMO

BACKGROUND: Kidney transplantation is considered the ideal treatment for most people with kidney failure, conferring both survival and quality of life advantages, and is more cost effective than dialysis. Yet, current health systems may serve some people better than others, creating inequities in access to kidney failure treatments and health outcomes. AcceSS and Equity in Transplantation (ASSET) investigators aim to create a linked data platform to facilitate research enquiry into equity of health service delivery for people with kidney failure in New Zealand. METHODS: The New Zealand Ministry of Health will use patients' National Health Index (NHI) numbers to deterministically link individual records held in existing registry and administrative health databases in New Zealand to create the data platform. The initial data linkage will include a study population of incident patients captured in the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA), New Zealand Blood Service Database and the Australia and New Zealand Living Kidney Donor Registry (ANZLKD) from 2006 to 2019 and their linked health data. Health data sources will include National Non-Admitted Patient Collection Data, National Minimum Dataset, Cancer Registry, Programme for the Integration of Mental Health Data (PRIMHD), Pharmaceutical Claims Database and Mortality Collection Database. Initial exemplar studies include 1) kidney waitlist dynamics and pathway to transplantation; 2) impact of mental illness on accessing kidney waitlist and transplantation; 3) health service use of living donors following donation. CONCLUSION: The AcceSS and Equity in Transplantation (ASSET) linked data platform will provide opportunity for population-based health services research to examine equity in health care delivery and health outcomes in New Zealand. It also offers potential to inform future service planning by identifying where improvements can be made in the current health system to promote equity in access to health services for those in New Zealand.

RESUMO

RATIONALE & OBJECTIVE: In Aotearoa/New Zealand, Indigenous Maori experience inequitable delivery of kidney transplantation despite disproportionately higher rates of kidney failure. This study describes Maori patients' and families' values, perspectives, and experiences related to kidney transplantation. STUDY DESIGN: Qualitative interview study. SETTING & PARTICIPANTS: We conducted 40 in-depth interviews of 40 Maori: 8 who had received a transplant, 20 with chronic kidney disease (which included 10 on the deceased donor transplant list, 9 who were interested in transplantation and not currently waitlisted or who were ineligible for waitlisting, and 1 who was not interested in transplantation), 4 live-kidney donors, and 8 family members including 6 who had experiences with donor assessment. ANALYTICAL APPROACH: Data were analyzed inductively to generate themes and a conceptual framework. RESULTS: We identified 5 major themes: actively seeking a kidney transplant; evolving attitudes toward traditional values and practices; being confronted by interpersonal and systemic racism; poor information and communication; and challenged by social determinants of health. LIMITATIONS: Participants were recruited nationally through patient advocacy organizations and 1 regional kidney service. Potential participants unrelated to these groups or region could not be included. CONCLUSIONS: Maori participants were highly motivated to seek kidney transplantation and were inspired by positive experiences through donating and receiving a kidney. However, they faced barriers including social determinants, racism, and lack of information that impacted both direct experiences of transplantation and access to transplantation services.

RESUMO

AIMS: People with chronic kidney disease (CKD) living in rural communities have increased risks of death, morbidity, hospitalization and poorer quality of life compared with people with CKD living in urban areas. This study explores the experiences and perceptions of rural and remote patients and families in relation to accessing health services for kidney disease in Aotearoa New Zealand. METHODS: We conducted an In-depth interview study. We purposively sampled adult patients with CKD and their caregivers who lived further than 100 km (62 miles) or more than 1 h drive from their nearest dialysis or transplant centre. Qualitative data were analyzed inductively to generate themes, subthemes and a conceptual framework. RESULTS: Of 35 participants, including 26 patients and nine caregivers, 51% were female, 71% travelled between 1 and 3 h to their nearest renal unit, and the remainder, between 3 and 6 h. We identified five themes and related subthemes: intense psychological impact of rurality; pressure of extended periods away from home; services not designed for rural and remote living; suffering from financial losses; and poor communication. CONCLUSION: Rural and remote patients with CKD and their caregivers face the added challenges of separation from family, social and community support and financial burden, which can have profound consequences on their psychological and physical well-being and that of their families.

RESUMO

BACKGROUND: Eliminating indigenous and ethnic health inequities requires addressing the determinants of health inequities which includes institutionalised racism, and ensuring a health care system that delivers appropriate and equitable care. There is growing recognition of the importance of cultural competency and cultural safety at both individual health practitioner and organisational levels to achieve equitable health care. Some jurisdictions have included cultural competency in health professional licensing legislation, health professional accreditation standards, and pre-service and in-service training programmes. However, there are mixed definitions and understandings of cultural competency and cultural safety, and how best to achieve them. METHODS: A literature review of 59 international articles on the definitions of cultural competency and cultural safety was undertaken. Findings were contextualised to the cultural competency legislation, statements and initiatives present within Aotearoa New Zealand, a national Symposium on Cultural Competence and Maori Health, convened by the Medical Council of New Zealand and Te Ohu Rata o Aotearoa - Maori Medical Practitioners Association (Te ORA) and consultation with Maori medical practitioners via Te ORA. RESULTS: Health practitioners, healthcare organisations and health systems need to be engaged in working towards cultural safety and critical consciousness. To do this, they must be prepared to critique the 'taken for granted' power structures and be prepared to challenge their own culture and cultural systems rather than prioritise becoming 'competent' in the cultures of others. The objective of cultural safety activities also needs to be clearly linked to achieving health equity. Healthcare organisations and authorities need to be held accountable for providing culturally safe care, as defined by patients and their communities, and as measured through progress towards achieving health equity. CONCLUSIONS: A move to cultural safety rather than cultural competency is recommended. We propose a definition for cultural safety that we believe to be more fit for purpose in achieving health equity, and clarify the essential principles and practical steps to operationalise this approach in healthcare organisations and workforce development. The unintended consequences of a narrow or limited understanding of cultural competency are discussed, along with recommendations for how a broader conceptualisation of these terms is important.

RESUMO

BACKGROUND: Kidney transplantation is considered best practice treatment for end stage kidney disease (ESKD), however Indigenous patients are substantially less likely to receive either a deceased or live donor kidney transplant than non-Indigenous patients. We describe Indigenous peoples' experiences and perspectives including traditional values around kidney transplantation to inform international transplant programs. METHODS: We conducted a systematic review of qualitative studies involving Indigenous adults who have experience with or perceptions of kidney transplantation. We searched MEDLINE, Embase, PsychINFO, and CINAHL, in conjunction with analysis of Google Scholar and reference lists of related studies till July 2019. We utilised thematic synthesis to analyse data. Completeness of reporting in studies was evaluated using the Consolidated Criteria for Reporting Qualitative Studies (COREQ) framework. RESULTS: Eight studies involving 225 Indigenous participants were included. Five themes were identified: strong desire for transplantation (seeking normality and freedom from dialysis, wanting to reduce burden of disease within community); lack of partnership in shared decision-making (receiving inadequate information, ineffective communication); barriers to live kidney donation (difficulty asking, apprehension about impact on donor, avoiding additional financial burden and fear of complications); cultural considerations (influence of traditional values and beliefs, reconciling traditional values with pragmatic need); and experiencing lack of cultural competence in clinical care (struggling with prejudice and ignorance, mistrust of clinicians and health system). CONCLUSION: Indigenous participants had a strong desire for a kidney transplant and recognised the need for more readily available kidney transplants for others in their communities with ESKD. However, they faced prejudice and a lack of cultural competence by health workers as well as wider barriers to transplantation in systems that did not support effective and culturally appropriate delivery of information and care. Traditional cultural values also influenced decisions regarding kidney transplantation but such values were moderated when considering transplantation. Transplantation programs need to identify and mitigate barriers, such as the financial burden, promote cultural safety and incorporate traditional values into the promotion of transplantation in order to address inequitable transplantation rates.

RESUMO

BACKGROUND: In 2012, the Ohio State University College of Medicine (OSUCOM) implemented a new undergraduate medical curriculum. We compare outcomes of a third year traditional clerkship format to a combined Surgery and Obstetrics/Gynecology 'ring'. METHODS: Performance outcomes of 4 consecutive classes were compared between pre- (2014, 2015) and post-curricular revision (2016, 2017). RESULTS: Three hundred ninety-one students consented use of their educational data for research. We examined medical knowledge (NBME scores, USMLE Step 1 and Step 2 CK scores) and student satisfaction between pre- and post-curricular revision. Results demonstrated no statistically significant difference in the Obstetrics/Gynecology NBME shelf examination. Surgery NBME and USMLE Step 2 scores were increased and statistically significant but satisfaction of both disciplines was higher pre-curricular revision. CONCLUSION: Medical knowledge outcomes in this combined 'ring' were similar to or higher than performance in previous years'. Future analyses are needed to assess the impact of OSUCOM curricular revision.

RESUMO

PROBLEM: Faculty coaching is recognized as an essential element for effective use of portfolios in undergraduate medical education, yet best practices for training these coaches are uncertain. INTERVENTION: New portfolio coaches participated in a multifaceted training program that included orienting modules, a 7.5-hr training workshop featuring analysis of reflective writing, an Observed Structured Teaching Exercise (OSTE), and subsequent longitudinal coaches' meetings for timely task training. Four desired coaching skills were emphasized in the initial training: creating a safe environment, explicitly using performance data, asking questions that elicit reflection, and guiding the student to develop future goals and plans. We collected and analyzed several outcomes: (a) coaches' self-assessment at key intervals, (b) open-ended written responses to three coaching vignettes, (c) video recordings of the OSTE, and (d) subsequent student evaluation of the coach. In an attempt to capture learning from the workshop, both the responses to written vignettes and the video-recorded encounters were coded for presence or absence of the four desired skills. CONTEXT: Our portfolio and coaching program was instituted as part of a major undergraduate medical education reform. A new cohort of 25 coaches is enrolled with each matriculating student class, and each coach is assigned to work individually with 8-10 students, forming a coaching relationship that continues over 4 years. Coaches are compensated at 5% full-time equivalent. OUTCOME: On coach self-assessment, the majority of coaches reported significant improvement in their perceived ability to assess a student's level of reflection, enhance reflection, use performance data, and guide a student to develop goals and plans. After two semesters, coach perception of improved abilities persisted. Students rated coaches as excellent (82%), reporting that coaches created safe environments (99%), promoted insight (92%), and aided in goal setting (97%). Written responses to vignettes before the OSTE found that several coaches omitted desired behaviors; however, posttraining responses showed no discernable pattern of learning. Coding of the OSTE, in contrast, documented that all coaches demonstrated all four of the desired skills. LESSONS LEARNED: Although coaches reported learning related to key skills, learning was not apparent when responses to written vignettes were examined. In contrast, skills were demonstrated in the OSTE, perhaps due to the added structured tasks as well as anticipation of feedback. In conclusion, this portfolio coach training program achieved its desired aim of providing students with portfolio coaches who demonstrated the desired skills, as reported by both coaches and students.

RESUMO

This article was migrated. The article was marked as recommended. Objectives: To evaluate satisfaction among third year medical students with a bedside teaching exercise comprised of direct observation of student-performed physical examination skills and related feedback. Methods: An observational, cross-sectional study design was employed to study third year medical students undergoing the Neurology clerkship at the Ohio State University College of Medicine between June and October 2015. Immediately following the bedside physical examination teaching exercise, student satisfaction data was obtained in anonymous survey (n=21). In addition, student satisfaction data from the class cohort (n=51), regarding various learning formats in the curriculum, were collected at the end of a 16-week block of rotations including the Neurology clerkship. Data were summarized using descriptive statistics. Results: Most students felt that their level of confidence increased as a result (85.0%, n=17/21), and they felt they would use what they had learned in the future (95%, n=19/21). Only about half of the students felt strongly that reflection on the learning experience was sought (47.6%, n= 10/21). At the end of the 16 weeks block, the Neurology examination exercise was rated among the most highly in student satisfaction (3.35/4, SD=0.89) as compared to procedural workshops (2.76/4, SD= 0.76), other small group topic format (2.78/4, SD= 0.85), and traditional lecture (2.39/ 4, SD= 0.89). Conclusions: The bedside direct observation of physical examination performed by medical students is highly rated in student satisfaction, and students are most satisfied with this format of teaching among all formats studied. Increased opportunity for reflection in this setting represents an area for further development.

RESUMO

The Circadian Amplitude and Phase Scale (CAPS) is a new self-report tool that aims to assess amplitude and phase. The CAPS consists of three factors made up of 38 items. Amplitude is posited to be assessed via two of these factors: time awareness (TA) and/or strength of preference (SOP). The remaining factor, phase, is assessed via the existing Preferences Scale (PS). Given there is no published research using this measure, the authors undertook two studies to examine its psychometric properties and construct validity. In a sample of 351 North American students, the authors identified a three-factor 34-item model using principal components analysis. The components explained 39% of the variance, and scale reliability ranged from 0.73 (SOP) to 0.88 (PS). The correlations between the components were small, suggesting they are each assessing different constructs. Thus, it is unlikely TA and SOP may both be indicators of amplitude. The distributions for each scale were divided into two groups (≤ 25th and ≥ 75th percentiles), and these groups were used to assess construct validity using alertness ratings by time-of-day. The results from a multivariate general linear model indicated a significant difference (p < .001) in sleepiness ratings by time-of-day for the PS scale only. In the second study, the authors applied confirmatory factor analysis in an attempt to replicate the factor structure identified in the student sample in a working sample (n = 388). The results suggested the model fit was not optimal. Subsequent analysis suggested a 26-item model was a better fit, but it also was not optimal. The intercorrelations between the factors were larger than in the student sample but again small, indicating the constructs are independent measures. The inability to replicate the factor structure is most likely explained by the differences in the sample characteristics of age, sex, and perhaps difficulty in interpreting the items. The limitations of these studies are discussed and recommendations for future studies are made.

RESUMO

The goals of this study were twofold: (1) to confirm a relationship between employee perceptions of psychological safety climate and safety behavior for a sample of workers in the rail industry and (2) to explore the relative strengths of relationships between specific facets of safety climate and safety behavior. Non-management rail maintenance workers employed by a large North American railroad completed a survey (n=421) regarding workplace safety perceptions and behaviors. Three facets of safety climate (management safety, coworker safety, and work-safety tension) were assessed as relating to individual workers' reported safety behavior. All three facets were significantly associated with safety behavior. Dominance analysis was used to assess the relative importance of each facet as related to the outcome, and work-safety tension evidenced the strongest relationship with safety behavior.
