RESUMO

Allied health primary contact clinic models of care have increasingly been used as a strategy to increase public health service capacity. A recent systematic review found little consistency or agreement on how primary contact clinics are evaluated. The concept of value of primary contact clinics, which has important implications for evaluation, has not yet been explored in-depth. To explore allied health clinicians' perceptions of the value of allied health primary contact clinics, with the goal of informing an evaluation framework, a descriptive qualitative approach utilizing semi-structured interviews was employed. Participants included allied health staff embedded in clinical lead roles within primary contact clinics across four acute care hospitals in a metropolitan health service located in South-East Queensland, Australia. Lead staff from 30 identified primary contact clinic models in the health service were approached to take part via email. All eligible participants who provided consent were included. An inductive thematic analysis approach was used. A total of 23 clinicians (n = 23) representing 22 diverse models of primary contact clinics participated. Most participants were physiotherapists, dietitians, or occupational therapists, although speech pathology, audiology, and podiatry were also represented. Participant perceptions of the 'value' of PCCs were a highly complex phenomenon, comprising five intersecting domains: (i) patient satisfaction; (ii) clinical outcomes; (iii) care pathway and resource use; (iv) health service performance; and (v) staff satisfaction and professional standing. These five core value domains were positively or negatively influenced by 12 perceived benefits and 8 perceived drawbacks, respectively. Value domains were also highly interrelated and impacted upon each other. The concept of 'value' relating to primary contact clinics involves multiple intersecting domains encompassing different perspectives. This study highlighted potential benefits and drawbacks of primary contact clinics that have not yet been measured or explored in the literature, and as such may be useful for healthcare administrators to consider. The findings of this study will inform an evaluation framework including health economics calculator for primary contact clinics.

RESUMO

INTRODUCTION: Cabotegravir and rilpivirine (CAB+RPV long-acting (LA)) is recommended as a treatment for HIV-1 allowing people living with HIV to receive 2 monthly injectable treatment, rather than daily pills. Providing injectable therapy in a system designed to provide and manage study participants on oral treatments poses logistical challenges namely how resources are used to accommodate patient preference within constrained health economies with capacity limitations. In this pragmatic multicentre study, we aim to understand the implementation of CAB-RPV-LA administration in two settings via mixed methods to explore perspectives of participants and the clinical team delivering CAB+RPV LA. METHODS AND ANALYSIS: Women, racially minoritised people and older people are chronically under-represented in HIV clinical trials so the ILANA trial has set recruitment caps to ensure recruitment of 50% women, 50% ethnically diverse people and 30% over 50 years of age to include a more representative study population. Using a mixed-methods approach, the primary objective is to identify and evaluate the critical implementation strategies for CAB+RPV LA in both hospital and community settings. Secondary objectives include evaluating feasibility and acceptability of CAB+RPV LA administration at UK clinics and community settings from the perspective of HIV care providers, nurses and representatives at community sites, evaluating barriers to implementation, the utility of implementation strategies and adherence. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Health Research Authority Research Ethics Committee (REC reference: 22/PR/0318). The dissemination strategy has been formulated with the SHARE Collaborative Community Advisory Board to maximise the impact of this work on clinical care and policy. This strategy draws on and leverages existing resources within the participating organisations, such as their academic infrastructure, professional relationships and community networks. The strategy will leverage the Public Engagement Team and press office to support dissemination of findings. TRIAL REGISTRATION NUMBER: NCT05294159.

RESUMO

A cost-minimization analysis was conducted for Klebsiella pneumoniae liver abscess (KLA) patients enrolled in a randomized controlled trial which found oral ciprofloxacin to be non-inferior to intravenous (IV) ceftriaxone in terms of clinical outcomes. Healthcare service utilization and cost data were obtained from medical records and estimated from self-reported patient surveys in a non-inferiority trial of oral ciprofloxacin versus IV ceftriaxone administered to 152 hospitalized adults with KLA in Singapore between November 2013 and October 2017. Total costs were evaluated by category and payer, and compared between oral and IV antibiotic groups over the trial period of 12 weeks. Among the subset of 139 patients for whom cost data were collected, average total cost over 12 weeks was $16,378 (95% CI, $14,620-$18,136) for the oral ciprofloxacin group and $20,569 (95% CI, $18,296-$22,842) for the IV ceftriaxone group, largely driven by lower average outpatient costs, as the average number of outpatient visits was halved for the oral ciprofloxacin group. There were no other statistically significant differences, either in inpatient costs or in other informal healthcare costs. Oral ciprofloxacin is less costly than IV ceftriaxone in the treatment of Klebsiella liver abscess, largely driven by reduced outpatient service costs.Trial registration: ClinicalTrials.gov Identifier NCT01723150 (7/11/2012).

RESUMO

INTRODUCTION: Postoperative morbidity and mortality in patients undergoing major emergency gastrointestinal surgery are a major burden on healthcare systems. Optimal management of perioperative intravenous fluids may reduce mortality rates and improve outcomes from surgery. Previous small trials of cardiac-output guided haemodynamic therapy algorithms in patients undergoing gastrointestinal surgery have suggested this intervention results in reduced complications and a modest reduction in mortality. However, this existing evidence is based mainly on elective (planned) surgery, with little evaluation in the emergency setting. There are fundamental clinical and pathophysiological differences between the planned and emergency surgical setting which may influence the effects of this intervention. A large definitive trial in emergency surgery is needed to confirm or refute the potential benefits observed in elective surgery and to inform widespread clinical practice. METHODS: The FLO-ELA trial is a multi-centre, parallel-group, open, randomised controlled trial. 3138 patients aged 50 and over undergoing major emergency gastrointestinal surgery will be randomly allocated in a 1:1 ratio using minimisation to minimally invasive cardiac output monitoring to guide protocolised administration of intra-venous fluid, or usual care without cardiac output monitoring. The trial intervention will be carried out during surgery and for up to 6 h postoperatively. The trial is funded through an efficient design call by the National Institute for Health and Care Research Health Technology Assessment (NIHR HTA) programme and uses existing routinely collected datasets for the majority of data collection. The primary outcome is the number of days alive and out of hospital within 90 days of randomisation. Participants and those delivering the intervention will not be blinded to treatment allocation. Participant recruitment started in September 2017 with a 1-year internal pilot phase and is ongoing at the time of publication. DISCUSSION: This will be the largest contemporary randomised trial examining the effectiveness of perioperative cardiac output-guided haemodynamic therapy in patients undergoing major emergency gastrointestinal surgery. The multi-centre design and broad inclusion criteria support the external validity of the trial. Although the clinical teams delivering the trial interventions will not be blinded, significant trial outcome measures are objective and not subject to detection bias.

RESUMO

OBJECTIVE: The MeCare programme is a tailored virtual care initiative targeted at frequent users of health services who have at least one chronic condition including cardiovascular disease, chronic respiratory disease, diabetes or chronic kidney disease. The programme aims to prevent unnecessary hospitalisations by helping patients to self-manage, improve their health literacy and engage in positive health behaviours. This study investigates the impact of the MeCare programme on healthcare resource use, costs and patient-reported outcomes. METHODS AND ANALYSIS: A retrospective pre-post study design was adopted. Data on emergency department presentations, hospital admissions, outpatient appointments and their associated costs were obtained from administrative databases. Probabilistic sensitivity analysis using Monte Carlo simulation was used to model changes in resource use and costs prior to, and following, participant enrolment on the MeCare programme. Generalised linear models were used to investigate the observed changes in patient-reported outcomes. RESULTS: The MeCare programme cost $A624 per participant month to deliver. Median monthly rates of ED presentations, hospital admissions and average length of stay post-MeCare reduced by 76%, 50% and 12%, respectively. This translated to a median net cost saving of $A982 per participant month (IQR: -1936; -152). A significant, positive trend in patient experience based on responses to the Patient Assessment of Care for Chronic Conditions Questionnaire was observed over the duration of programme enrolment. DISCUSSION: The MeCare programme is likely to result in substantial cost savings to the health system, while maintaining or improving patient-reported outcomes. Further research in multisite randomised studies is needed to confirm the generalisability of these results.

RESUMO

BACKGROUND: Perinatal mental health difficulties affect up to 27% of birthing parents during pregnancy and the first postnatal year, and if untreated are associated with difficulties in bonding and long-term adverse outcomes to children. There are large evidence gaps related to psychological treatment, particularly in group therapy approaches and parent-infant interventions. One intervention showing preliminary efficacious findings and user acceptability is Circle of Security-Parenting (COS-P), which is a brief, weekly, group programme. However, these studies were underpowered and predominantly non-randomised, and there has never been a research trial in England or with birthing parents experiencing severe and complex perinatal mental health difficulties. The aim of the research is to conduct a randomised control trial to test whether COS-P will reduce perinatal mental health symptoms in birthing parents accessing NHS perinatal mental health services, compared to treatment as usual (TAU). Secondary objectives include exploring whether the intervention improves parenting sensitivity, emotion regulation skills, attachment security and infant development. Additionally, the project aims to examine whether the intervention is acceptable to parents and NHS staff, and whether it is cost-effective. METHODS: COSI is an individually randomised, single-blind parallel arm controlled trial with an embedded internal pilot aiming to recruit 369 participants in a 2:1 ratio (intervention: TAU). Participants will be recruited from ten NHS community perinatal mental health services in England and screened based on clinical levels of both mental health symptoms (average CORE-OM score ≥ 1.1) and postnatal bonding difficulties (total PBQ score ≥ 12). This trial has 90% power to detect a MCID of 5 points on the CORE-OM. Primary and secondary outcomes will be measured at baseline, 3, 7 and 12 months after baseline. Service use and quality of life measures will also be collected alongside a process evaluation of parents' and interveners' views and experiences. DISCUSSION: This will be the first large pragmatic trial to test whether COS-P is effective for birthing parents with severe and complex perinatal mental health difficulties in improving their mental health symptoms. If shown to be effective, the intervention could be delivered widely across the NHS and other similar services globally. TRIAL REGISTRATION: ISRCTN, ISRCTN18308962. Registered 18 February 2022.

RESUMO

BACKGROUND: Social marginalization and criminalization create health and safety risks for sex workers and reduce their access to health promotion and prevention services compared to the general population. Community empowerment-based interventions that prioritize the engagement of sex workers show promising results. Peer-to-peer interventions, wherein sex workers act as educators of their colleagues, managers, clients and romantic partners, foster community mobilization and critical consciousness among sex workers and equip them to exercise agency in their work and personal lives. METHODS: A pilot peer health education program was developed and implemented, with and for sex workers in one urban centre in Canada. To explore how the training program contributed to community empowerment and transformative learning among participants, the authors conducted qualitative interviews, asked participants to keep personal journals and to fill out feedback forms after each session. Thematic analysis was conducted on these three data sources, with emerging themes identified, organized and presented in the findings. RESULTS: Five themes emerged from the analysis. Our findings show that the pilot program led to reduced internalized stigma and increased self-esteem in participants. Participants' critical consciousness increased concerning issues of diversity in cultural background, sexual orientation, work experiences and gender identity. Participants gained knowledge about how sex work stigma is enacted and perpetuated. They also became increasingly comfortable challenging negative judgments from others, including frontline service providers. Participants were encouraged to actively shape the training program, which fostered positive relationships and solidarity among them, as well as with colleagues in their social network and with the local sex worker organization housing the program. Resources were also mobilized within the sex worker community through skills building and knowledge acquisition. CONCLUSION: The peer education program proved successful in enhancing sex workers' community empowerment in one urban setting by increasing their knowledge about health issues, sharing information about and building confidence in accessing services, and expanding capacity to disseminate this knowledge to others. This 'proof of concept' built the foundation for a long-term initiative in this setting and has promise for other jurisdictions wishing to adapt similar programs.

RESUMO

OBJECTIVE: To analyze patients' perception of implant therapy in partial edentulism, after 5 years with implant-supported reconstructions. MATERIAL AND METHODS: Patients who received dental implants at the National Dental Centre, Singapore 3-9 years earlier (mean: 5.2 years) were invited to participate in the study. Responders were examined clinically, and asked to answer a questionnaire with 13 statements. RESULTS: Of the 880 patients, 206 patients, with 329 implants, agreed to participate. Of the implants, 82% supported single crowns, while 18% were reconstructed with splinted crowns or fixed dental prostheses. Function and chewing comfort yielded high patient satisfaction. Comparing chewing comfort for teeth and implants, respectively, 51% perceived no difference between the two. Patients were largely satisfied with the phonetic function and esthetic outcome. Only two in three patients were able to cleanse the implant reconstruction well, and majority of the patients reported no difference comparing the time taken to clean implants and teeth. Patients were generally unsure if the tissues around their implants or teeth bled more. Pertaining to expectations, most patients were satisfied with the treatment, and majority were willing to undergo the same treatment again. Most patients would recommend such treatment to friends, if indicated. Only slightly over one-third of the patients felt certain that the cost of the treatment was justified. CONCLUSION: The large majority was satisfied with the functional outcomes of implant treatment. However, the patients had a less than ideal understanding of gingival health around teeth and implants. Patients were less discerning than clinicians in the assessment of esthetic outcomes.

RESUMO

BACKGROUND: Eyes sustaining open globe trauma are at high risk of severe visual impairment. Ocular injuries which result in visual loss invariably affect the posterior segment of the eye, and prevention of visual loss involves posterior segment (vitreoretinal) surgery. Despite improvements in vitreoretinal surgical techniques, outcomes in these patients remain unsatisfactory, and development of the intraocular scarring response proliferative vitreoretinopathy is the leading cause. Proliferative vitreoretinopathy is the most common cause of recurrent retinal detachment in these eyes; it is reported to occur in up to 45 % of cases. METHODS/DESIGN: The Adjunctive Steroid Combination in Ocular Trauma (ASCOT) trial is a multi-centre, double-masked, parallel-arm randomised controlled trial with an internal pilot designed to investigate the effectiveness and cost-effectiveness of using intravitreal and sub-Tenon's triamcinolone acetonide peri-operatively in patients undergoing vitrectomy following open globe trauma. In total, 300 eyes of 300 patients will be recruited and randomly allocated to one of two treatment groups. Both groups will receive standard surgical treatment and routine pre-operative and post-operative treatment and care. The treatment group will receive an adjunctive peri-operative steroid combination (triamcinolone acetonide) consisting of 4 mg/0.1 ml into the vitreous cavity and 40 mg/1 ml into the sub-Tenon's space. The trial incorporates a two-stage internal pilot to examine projected recruitment and retention rates. Progression criteria from the internal pilot study will enable us to determine whether to undertake the main trial. Patients and primary outcome assessors will be masked to treatment allocation. The primary outcome will be an improvement from baseline to 6 months of at least 10 on the corrected visual acuity as measured by ETDRS letter score. Secondary outcomes will be development of scarring, retinal detachment, intraocular pressure abnormalities, quality of life and public sector service use. DISCUSSION: This is the first powered, controlled clinical trial to investigate the use of adjunctive triamcinolone in patients undergoing vitrectomy following open globe trauma.

RESUMO

OBJECTIVE: There is no established minimum clinically important difference (MCID) for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) index and total scale scores. This study aimed to estimate the MCID for the RBANS index scores and total scale score. METHOD: Participants included 1,856 ethnic Chinese, older adults. Distribution- and anchor-based methods were used to estimate values for the MCID. Distribution-based estimates were calculated as the standard error of measurement (SEM) and .5 standard deviations (SD). For anchor-based estimates, we compared RBANS scores between the clinical dementia rating (CDR) scale no dementia and very mild dementia groups and between the clinical assessment of dementia (CAD) cognitively normal and mild cognitive impairment groups using regression models adjusting for demographic characteristics. RESULTS: Estimates from the CDR anchor were 7.79, 8.63, 10.74, 9.74, 5.61, and 3.77 for the total scale score, language, immediate memory, delayed memory, visuospatial/constructional, and the attention index, respectively. Estimates from the distribution-based methods were similar to the estimates based on the CDR, except for the language and attention indexes. Estimates from the CAD anchor were larger. CONCLUSIONS: We estimated the MCID for the total scale score, language, immediate memory, delayed memory, visuospatial/constructional, and attention indexes of the RBANS as 8, 9, 10, 10, 6, and 4 points, respectively. These estimates are best suited to discriminate between patient groups, for example, in a clinical trial setting. Further research is needed using longitudinal data to assess their applicability to assess within patient differences.

RESUMO

OBJECTIVE: Chinese is the most commonly spoken language in the world. The availability of Chinese translations of assessment scales is useful for research in multi-ethnic and multinational studies. This study aimed to establish whether each of the Chinese translations (Mandarin, Hokkien, Teochew, and Cantonese) of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) achieved measurement equivalence to the English version. METHOD: Participants included 1856 ethnic Chinese, older adults. The RBANS was administered in the language/dialect according to the participants' preference by interviewers who were fluent in that language/dialect. Multiple regression analysis was used to adjust for demographic and clinical differences between participants who spoke different languages/dialects. Equivalence (practical equivalence) was declared if the 90% confidence interval for the adjusted mean difference fell entirely within the pre-specified equivalence margin, ±.2 (±.4) standard deviations. RESULTS: The delayed memory index was at least practically equivalent across languages. The Mandarin, Hokkien, and Teochew versions of the immediate memory, language, and total scale score were practically equivalent to the English version; the Cantonese version showed small differences from the English version. Equivalence was not established for the Hokkien and Teochew versions of the visuospatial/constructional index. The attention index was different across languages. CONCLUSIONS: Data from the English and Chinese versions for the total scale score, language, delayed, and immediate memory indexes may be pooled for analysis. However, analysis of the attention and visuospatial/constructional indexes from the English and Chinese versions should include a covariate that represents the version in the statistical adjustment.

RESUMO

BACKGROUND: There is growing evidence that cognitive training (CT) can improve the cognitive functioning of the elderly. CT may be influenced by cultural and linguistic factors, but research examining CT programs has mostly been conducted on Western populations. We have developed an innovative electroencephalography (EEG)-based brain-computer interface (BCI) CT program that has shown preliminary efficacy in improving cognition in 32 healthy English-speaking elderly adults in Singapore. In this second pilot trial, we examine the acceptability, safety, and preliminary efficacy of our BCI CT program in healthy Chinese-speaking Singaporean elderly. METHODS: Thirty-nine elderly participants were randomized into intervention (n=21) and wait-list control (n=18) arms. Intervention consisted of 24 half-hour sessions with our BCI-based CT training system to be completed in 8 weeks; the control arm received the same intervention after an initial 8-week waiting period. At the end of the training, a usability and acceptability questionnaire was administered. Efficacy was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), which was translated and culturally adapted for the Chinese-speaking local population. Users were asked about any adverse events experienced after each session as a safety measure. RESULTS: The training was deemed easily usable and acceptable by senior users. The median difference in the change scores pre- and post-training of the modified RBANS total score was 8.0 (95% confidence interval [CI]: 0.0-16.0, P=0.042) higher in the intervention arm than waitlist control, while the mean difference was 9.0 (95% CI: 1.7-16.2, P=0.017). Ten (30.3%) participants reported a total of 16 adverse events - all of which were graded "mild" except for one graded "moderate". CONCLUSION: Our BCI training system shows potential in improving cognition in both English- and Chinese-speaking elderly, and deserves further evaluation in a Phase III trial. Overall, participants responded positively on the usability and acceptability questionnaire.

RESUMO

BACKGROUND: Depression is common in people with coronary heart disease (CHD) and associated with worse outcome. This study explored the acceptability and feasibility of procedures for a trial and for an intervention, including its potential costs, to inform a definitive randomized controlled trial (RCT) of a nurse-led personalised care intervention for primary care CHD patients with current chest pain and probable depression. METHODS: Multi-centre, outcome assessor-blinded, randomized parallel group study. CHD patients reporting chest pain and scoring 8 or more on the HADS were randomized to personalized care (PC) or treatment as usual (TAU) for 6 months and followed for 1 year. Primary outcome was acceptability and feasibility of procedures; secondary outcomes included mood, chest pain, functional status, well being and psychological process variables. RESULT: 1001 people from 17 General Practice CHD registers in South London consented to be contacted; out of 126 who were potentially eligible, 81 (35% female, mean age = 65 SD11 years) were randomized. PC participants (n = 41) identified wide ranging problems to work on with nurse-case managers. Good acceptability and feasibility was indicated by low attrition (9%), high engagement and minimal nurse time used (mean/SD = 78/19 mins assessment, 125/91 mins telephone follow up). Both groups improved on all outcomes. The largest between group difference was in the proportion no longer reporting chest pain (PC 37% vs TAU 18%; mixed effects model OR 2.21 95% CI 0.69, 7.03). Some evidence was seen that self efficacy (mean scale increase of 2.5 vs 0.9) and illness perceptions (mean scale increase of 7.8 vs 2.5) had improved in PC vs TAU participants at 1 year. PC appeared to be more cost effective up to a QALY threshold of approximately £3,000. CONCLUSIONS: Trial and intervention procedures appeared to be feasible and acceptable. PC allowed patients to work on unaddressed problems and appears cheaper than TAU. TRIAL REGISTRATION: Controlled-Trials.com ISRCTN21615909.

RESUMO

IMPORTANCE: Geographic atrophy (GA) is the major cause of blind registration in Western communities, although, with few exceptions, it is less common than choroidal neovascular disease. The variation of phenotype implies that age-related macular degeneration (AMD) does not follow the same course from one case to another and that phenotyping may be important before initiating a therapeutic trial. OBJECTIVE: To document photoreceptor and retinal pigment epithelium (RPE) cell loss and other changes at the RPE-choroid interface in donated human eyes in which visual loss was deemed to be due to GA. DESIGN, SETTING, AND PARTICIPANTS: Histological study of a consecutive series of eyes donated by individuals previously diagnosed clinically as having GA. Donors were chosen on the basis of available clinical records (from MidAmerica Transplant Services, St Louis, Missouri; the Iowa Lions Eye Bank, Iowa City; and the Utah Lions Eye Bank, Salt Lake City) and selected were those considered to have GA due to AMD. Tissues in the regions of atrophy were examined with light, electron, and autofluorescence microscopy. RESULTS: In most of the 37 donors examined, there was marked loss of photoreceptor cells for variable distances distal from the edge of the GA. Rod loss was greater than cone loss. An inverse relationship existed between the quantity of autofluorescent inclusions in the RPE and the thickness of sub-RPE basal laminar deposit. Integrity of the choroid varied from one eye to another and was not related strictly to photoreceptor survival. In some eyes, photoreceptor loss existed in the absence of obvious morphological changes in the Bruch membrane or RPE. CONCLUSIONS AND RELEVANCE: The findings support the view that photoreceptor loss occurs early in AMD in a proportion of cases and imply that photoreceptor-cell loss may contribute to the functional loss recorded in early stages of AMD at least in part. The variation of changes from one eye to another implies that patients selected for a specific prophylactic therapy for early AMD should be chosen on the basis of the characteristics of their disease.

RESUMO

BACKGROUND: Klebsiella pneumoniae liver abscess is the most common etiology of liver abscess in Singapore and much of Asia, and its incidence is increasing. Current management includes prolonged intravenous antibiotic therapy, but there is limited evidence to guide oral conversion. The implicated K1/K2 capsule strain of Klebsiella pneumoniae is almost universally susceptible to ciprofloxacin, an antibiotic with high oral bioavailability. Our primary aim is to compare the efficacy of early (< one week) step-down to oral antibiotics, to continuing four weeks of intravenous antibiotics, in patients with Klebsiella liver abscess. METHODS/DESIGN: The study is designed as a multi-center randomized open-label active comparator-controlled non-inferiority trial, with a non-inferiority margin of 12%. Eligible participants will be inpatients over the age of 21 with a CT or ultrasound scan suggestive of a liver abscess, and Klebsiella pneumoniae isolated from abscess fluid or blood. Randomization into intervention or active control arms will be performed with a 1:1 allocation ratio. Participants randomized to active control will receive IV ceftriaxone 2 grams daily to complete a total of four weeks of IV antibiotics. Participants randomized to intervention will be immediately converted to oral ciprofloxacin 750 mg twice daily. At Week four, all participants will undergo abdominal imaging and be assessed for clinical response (CRP < 20 mg/l, absence of fever, plus scan showing that the maximal diameter of the abscess has reduced). If criteria are met, antibiotics are stopped; if not, oral antibiotics are continued, with reassessment for clinical response fortnightly. If criteria for clinical response are met by Week 12, the primary endpoint of clinical cure is met. A cost analysis will be performed to assess the cost saving of early conversion to oral antibiotics, and a quality of life analysis will be performed to assess whether treatment with oral antibiotics is less burdensome than prolonged IV antibiotics. DISCUSSION: Our results would help inform local and international practice guidelines regarding the optimal antibiotic management of Klebsiella liver abscess. A finding of non-inferiority may translate to the wider adoption of a more cost-effective strategy that reduces hospital length of stay and improves patient-centered outcomes and satisfaction. TRIAL REGISTRATION: Clinical trials gov NCT01723150.

RESUMO

UNLABELLED: Retrenchment of government services has occurred across a wide range of sectors and regions. Care services, in particular, have been clawed away in the wake of fiscal policies of cost containment and neoliberal policies centred on individual responsibility and market autonomy. Such policies have included the deinstitutionalisation of care from hospitals and clinics, and early discharge from hospital, both of which are predicated on the notion that care can be provided informally within families and communities. In this paper we examine the post-birth "care crisis" that new mothers face in one region of Canada. METHOD: The data are drawn from a larger study of social determinants of pregnant and new mothers' health in Victoria, Canada. Mixed methods interviews were conducted among a purposive sample of women at three points in time. This paper reports data on sample characteristics, length of stay in hospital and health service gaps. This data is contextualised via a more in-depth analysis of qualitative responses from Wave 2 (4-6 weeks postpartum). RESULTS: Out results show a significant portion of participants desired services that were not publically available to them during the post-birth period. Among those who reported a gap in care, the two most common barriers were: cost and unavailability of home care supports. Participants' open-ended responses revealed many positive features of the public health care system but also gaps in services, and economic barriers to receiving the care they wanted. The implications of these findings are discussed in relation to recent neoliberal reforms. DISCUSSION & CONCLUSIONS: While Canada may be praised for its public provision of maternity care, mothers' reports of gaps in care during the early postpartum period and increasing use of private doulas is a worrying trend. To the extent that individual mothers or families rely on the market for care provision, issues of equity and quality of care are pivotal. This paper concludes with suggestions for further research on the impact of recent changes in post-birth care on new fathers and on inequities in pre and post-birth care in less-resourced regions of the world.

RESUMO

Courtesy stigma, also referred to as 'stigma by association', involves public disapproval evoked as a consequence of associating with a stigmatised individual or group. While a small number of sociological studies have shown how courtesy stigma limits the social support and social opportunities available to family members of stigmatised individuals, there is a paucity of research examining courtesy stigma among the large network of people who provide health and social services to stigmatised groups. This article presents results from a mixed methods study of the workplace experiences of a purposive sample of workers in a non-profit organisation providing services to sex workers in Canada. The findings demonstrate that courtesy stigma plays a role in workplace health as it shapes both the workplace environment, including the range of resources made available to staff to carry out their work activities, as well as staff perceptions of others' support. At the same time, it was evident that some workers were more vulnerable to courtesy stigma than others depending on their social location. We discuss these results in light of the existing literature on courtesy stigma and conclude that it is an under-studied determinant of workplace health among care providers serving socially denigrated groups.
