RESUMO

AIMS: To explore the effectiveness of interventions to enhance patient participation in shared decision-making in wound care and tissue viability. BACKGROUND: Caring for people living with a wound is complex due to interaction between wound healing, symptoms, psychological wellbeing and treatment effectiveness. To respond to this complexity, there has been recent emphasis on the importance of delivering patient centred wound care and shared decision-making to personalise health care. However, little is known about the effectiveness of existing interventions to support shared decision-making in wound care. DESIGN: Systematic review of interventional studies to enhance shared decision-making in wound care or tissue viability. This was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines 2020. METHODS: Interventional primary research studies published in English up to January 2023 were included. Screening, data extraction and quality appraisal were undertaken independently by two authors. DATA SOURCES: Medline, EMBASE, Cochrane Central Register of Controlled Trails (trials database), CINAHL, British Nursing Index (BNI), WorldCat (thesis database), Scopus and registries of ongoing studies (ISRCTN registry and clinicaltrials.gov). RESULTS: 1063 abstracts were screened, and eight full-text studies included. Findings indicate, interventions to support shared decision-making are positively received. Goal or need setting components may assist knowledge transfer between patient and clinician, and could lower short term decisional conflict. However, generally findings within this study had very low certainty due to the inconsistencies in outcomes reported, and the variation and complexity of single and multiple interventions used. CONCLUSIONS: Future research on shared decision-making interventions in wound care should include the involvement of stakeholders and programme theory to underpin the interventions developed to consider the complexity of interventions. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Patients setting out their needs or goals and exploring patient questions are important and should be considered in clinical care. REGISTRATION: The review protocol was prospectively registered (PROSPERO database: CRD42023389820). NO PATIENT OR PUBLIC CONTRIBUTION: Not applicable as this is a systematic review.

RESUMO

In 2014, the United Nations Convention on the Rights of Disabilities adopted recommendations advising the replacement of involuntary care with supported care. This has polarised many about how best to provide for People living with Mental Conditions (PLPCs). Notwithstanding the contentions of this debate, we find on a personal discursive level that involuntary care is concealed as a self-evident and unquestionable response to the treatment of PLPCs. This can mean that policy-makers and professionals reproduce approaches to PLPCs uncritically. Considering these complexities, we used Critical Discourse Analysis (CDA) to examine what current norms surround involuntary care in the South African psy-complex, and how these are reproduced. We interviewed nine members of the South African psy-complex, including review board members, psychologists, and psychiatrists, and found several discourses maintaining current psychiatric norms. These include biomedical and techno-disciplinary discourses of treatment, clinico-legal disciplinary and danger discourses, and paternalistic discourses of institutional care. Each of these uniquely highlights the ways in which involuntary care is maintained and normalised, revealing that careful consideration is required to prevent potential human rights violations on behalf of professionals and policy-makers, regardless of whether in involuntary or support paradigms.

RESUMO

BACKGROUND: Deciding whether to transition to wound palliation is challenging for health care professionals because there is no agreed definition or understanding of palliative wound care, including the goals, core elements and differences from general wound management. OBJECTIVES: To conduct a scoping review with qualitative synthesis to define palliative wound care in terms of its conceptual framework, goals, principles, components, and differences from general wound management, and provide a new definition of palliative wound care based on this scoping review. ELIGIBILITY CRITERIA: Published literature that refers to the definitions, concept, goals and core elements of palliative wound care using any methodological approach, without any time limits, published in English. SOURCES OF EVIDENCE: The searches were conducted in CINAHL Complete via Ebsco, Medline via Ovid, Cochrane Library, Scopus, and Google Scholar. CHARTING METHODS: A data extraction form was developed by the review team and used independently for data charting purposes. Braun and Clarke's six phases of thematic analysis guided the qualitative synthesis. RESULTS: A total of 133 publications met the inclusion criteria. Three main themes were developed to define palliative wound care and understand its differences from general wound management: 1- Healing potential of wounds and patient vulnerability, 2- Understanding the impact on individuals and family to address needs, 3- Towards new goals and perspectives in approach to care. CONCLUSIONS: Palliative wound care focuses on symptom management, comfort, and dignity, but does not always target the healing of the wound, which is the goal of general wound care. The needs of the individual and their family must be addressed by clinicians through the provision of care and support that takes into account the true meaning of living and dying with a palliative wound. PROTOCOL REGISTRATION: A review protocol was developed but not registered.

RESUMO

OBJECTIVE: In autosomal recessive dystrophic Epidermolysis bullosa, repeat blistering results in finger webbing and severe contractures of the hands. The aim of this study was to codesign patient-reported outcome indicators for hand therapy with patients, carers and clinicians, and use these to proof-of-concept test a novel dressing glove for recessive dystrophic Epidermolysis bullosa, with cost analysis. METHOD: Qualitative interviews and focus groups with patients and carers generated content for the indicators. Validity and reliability were established through expert review, piloting and consensus between patients, carers and clinicians. The indicators were self-reported by patients before and while wearing the dressing glove in an N-of-1 study. Time for dressing changes and use of conventional products were also self-reported. RESULTS: A total of 11 indicators were initially generated from the thematic analysis. Expert review, piloting and consensus involved six patients, five carers and eight clinicians (total n=19). Participants agreed 14 indicators, covering hand skin condition (n=4), webbing between the digits (n=4), experiences of wearing and changing dressings (n=2), hand function (n=2), wrist function (n=1) and hand pain (n=1). In Phase 3, 12 patients scored indicators before wearing the gloves and four patients completed scoring while wearing the gloves. Statistically significant improvements between pre-glove and with-glove periods were found for most participants' experience scores. Skin appearance also improved for most participants. CONCLUSIONS: The indicators generated useful data, differentiation between scores and participants demonstrating proof-of-concept for patients with recessive dystrophic Epidermolysis bullosa who could wear the dressing gloves. The indicators are being used in routine practice, supporting clinical follow up, commercialisation and regulatory governance of the dressing glove.

RESUMO

OBJECTIVE: Recessive dystrophic epidermolysis bullosa (RDEB) is a rare genetic skin disorder which requires intensive hand therapy to delay fusion of the digits. Existing dressings do not conform to the complex structure of the hand and are applied in patches held with additional bandages, leading to an occlusive environment. The aim was to co-design with patients a dressing glove based on their user experiences and needs. METHOD: Qualitative interviews and focus groups with children and adults with RDEB, and their carers, were conducted. Iterative feedback of design cues, bench and surrogate testing of materials and prototype refinement were achieved through collaborative codesign with patients, carers, clinicians and manufacturers. RESULTS: Thematic analysis generated eight user needs and corresponding design cues, addressing issues of absorbency, adherence, comfort, adaptability, ease of application and removal, breathability, protection, and hand hygiene. A prototype was selected for proof of concept testing. CONCLUSION: This novel dressing glove design met the patient's requirements for a dressing, which conformed to the hand structure and sat in the web spaces to keep fingers separated. Proof of concept testing has since been undertaken with patients to determine performance, value for money and whether further developments are required.

RESUMO

INTRODUCTION: People with Xeroderma Pigmentosum (XP) have a heightened sensitivity to ultraviolet radiation (UVR) and are advised to wear photoprotective clothing including a visor covering the face and neck. Photoprotective visors are homemade and predominately worn by children with decreasing frequency as age increases. To improve upon the current design and efficacy we were tasked with developing a prototype visor to meet patients' needs. METHODS: Adopting a codesign methodology, patients' experiences of wearing a visor and patient and carer views of emerging prototypes were explored during interviews. A thematic analysis was conducted in parallel with data collection and themes were interpreted into design cues; desirable attributes of a visor that would counteract the negative user experiences and meet the requirements described by patients and carers. The design cues guided the iterative development of prototypes by academic engineers. RESULTS: Twenty-four interviews were conducted with patients and carers. Thematic analysis resulted in the following five themes: Being safe from UVR exposure; self-consciousness; temperature effects; acoustic difficulties; and material properties. The following design cues were developed from the themes respectively; materials and design with high UVR protection; ability to customise with own headwear; ventilation to reduce steaming up; acoustic functionality to enable hearing and speech; foldable, portable, and easy to put on and take off. CONCLUSIONS: It is important to understand people's experiences of using medical devices to improve their safety, efficiency and user satisfaction. The user experience themes and design cues, informed the iterative development of low fidelity visor prototypes as part of a codesign process. These design cues and responses to the prototypes are guiding commercial manufacturing and regulatory approval. The visor can then be prescribed to patients, providing an equitable service of care.

RESUMO

Introduction: Dupuytren's Disease is a fibroproliferative disorder of the hand, with a heterogenous pathogenesis, ranging from early-stage nodule development to late-stage digital contractures. Hand therapy intervention is not routinely provided pre-operatively. The objective of this systematic review was to explore the efficacy of hand therapy interventions provided for pre-operative Dupuytren's Disease. Methods: A systematic review was undertaken of the databases CENTRAL, CINAHL, OVID Medline and OVID EMBASE, PubMed, BNI, Web of Science, with grey literature and reference searches conducted from database inception to April 2022, and confirmed in August 2023. Included studies required non-surgical intervention and outcome data on individuals with Dupuytren's Disease who have not had surgical intervention. Two reviewers conducted the searches, independently assessed eligibility and completed methodological quality assessments. Data were summarised narratively. Results: Seventeen studies were selected for final inclusion. Interventions included Extracorporeal Shockwave Therapy (ESWT), Corticosteroid Injection (CSI), Splinting, Massage and Stretching, Ultrasound Therapy (US), Temperature Controlled High Energy Adjustable Laser (THEAL). ESWT positively maintained or improved pain, active range of motion (AROM), Disabilities of the Arm Shoulder, and Hand (DASH) scores, and grip strength. US positively maintained or improved ROM and grip. Splinting positively maintained or improved ROM, CSI positively improved nodule size. Cross Frictional Massage positively impacted AROM and THEAL improved pain and DASH scores. Conclusions: Outcomes from therapeutic interventions for pre-operative management of Dupuytren's Disease were largely positive. However, there is a need for further high-quality research into these interventions to understand their full potential for the management of Dupuytren's Disease.

RESUMO

AIMS AND OBJECTIVES: To explore the views of school nurses regarding mental health problems in young people and their potential for engaging in mental health work with this client group. BACKGROUND: Mental health problems in children and young people are an important public health issue. Universal children's services play a key role in identifying and managing these problems and, while school nurses have an important function in this work, little is known about their views on this aspect of their role. DESIGN: A qualitative research design employing focus group methodology. METHOD: School nurses (n = 33) were purposively sampled from four school nursing teams in two English cities for a series of focus groups. The focus group data were audio-recorded, transcribed and subsequently analysed using 'framework'. RESULTS: Four principal themes emerged from the data. In these themes, school nurses were found to value their involvement with the mental health of young people, recognising this as an important area of practice. Several obstacles to their work in this area were identified: heavy workloads, professional rivalries, a lack of confidence and limited education and training opportunities. The importance of support from local specialist mental health teams was emphasised. CONCLUSIONS: School nurses can be engaged in mental health work though, as public health specialists, their role should focus on health promotion, assessment, signposting and early intervention activities. To facilitate mental health work, school nurses are able to draw on established interpersonal skills and supportive networks; however, workload and a lack of confidence need to be managed and it is important that they are supported by constructive relationships with local specialist mental health teams. RELEVANCE TO CLINICAL PRACTICE: This study has implications for nurses and healthcare practitioners interested in enhancing the mental health of children and young people in school settings.

RESUMO

OBJECTIVE: To gain perspectives from family members about barriers and facilitators to virtual visit set up and conduct across intensive care unit settings in the United Kingdom to inform understanding of best practices. METHODS: We conducted a qualitative descriptive study recruiting a purposive sample of family members of adult intensive care unit patients experiencing virtual visiting during Jan to May 2021 of the COVID-19 pandemic. We used semi-structured qualitative interviews and a standard Thematic Analysis approach. RESULTS: We recruited 41 family-member participants from 16 hospitals in the United Kingdom. Facilitators to successful virtual visit set-up were preparation of the family, negotiating a preferred time, and easy-to-use technology. Facilitators to successful conduct were intensive care unit team member presence; enabling family involvement in care; inclusivity, accessibility, and flexibility; and having a sense of control. Barriers that created distress or conflict included restrictive virtual visiting practices; raising expectations then failing to meet them; lack of virtual visit pre-planning; and failing to prepare the patient. Barriers to visit conduct were incorrect camera positioning, insufficient technical and staff resources, issues with three-way connectivity, and lack of call closure. Recommendations included emotional self-preparation, increased technology availability, and preparing conversation topics. CONCLUSION: These data may guide virtual visiting practices during the ongoing pandemic but also to continue virtual visiting outside of pandemic conditions. This will benefit family members suffering from ill health, living at a distance, unable to afford travel, and those with work and care commitments, thereby reducing inequities of access and promoting family-centered care.

RESUMO

BACKGROUND: While studies have examined the impact of digital communication technology on healthcare, there is little exploration of how new models of digital care change the roles and identities of the health professional and patient. The purpose of the current study is to generate multidisciplinary reflections and questions around the use of digital consulting and the way it changes the meaning of being a patient and/or a health professional. METHOD: We used a large pre-existing qualitative dataset from the Long-term Conditions Young People Networked Communication (LYNC) study which involved interviews with healthcare professionals and a group of 16-24 years patients with long-term physical and mental health conditions. We conducted a three-stage mixed methods analysis. First, using a small sample of interview data from the LYNC study, we identified three key themes to explore in the data and relevant academic literature. Second, in small groups we conducted secondary analysis of samples of patient and health professional LYNC interview data. Third, we ran a series of rapid evidence reviews. FINDINGS: We identified three key themes: workload/flow, impact of increased access to healthcare and vulnerabilities. Both health professionals and patients were 'on duty' in their role more often. Increased access to healthcare introduced more responsibilities to both patients and health professionals. Traditional concepts in medical ethics, confidentiality, empathy, empowerment/power, efficiency and mutual responsibilities are reframed in the context of digital consulting. CONCLUSIONS: Our collaboration identified conflicts and constraints in the construction of digital patients and digital clinicians. There is evidence that digital technologies change the nature of a medical consultation and with it the identities and the roles of clinicians and patients which, in turn, calls for a redefinition of traditional concepts of medical ethics. Overall, digital consulting has the potential to significantly reduce costs while maintaining or improving patient care and clinical outcomes. Timely study of digital engagement in the National Health Service is a matter of critical importance.

RESUMO

For developmental as well as epidemiological reasons, young people need youth-friendly models of primary care. Over the past two decades, much has been written about barriers faced by young people in accessing health care. Worldwide, initiatives are emerging that attempt to remove these barriers and help reach young people with the health services they need. In this paper, we present key models of youth-friendly health provision and review the evidence for the effect of such models on young people's health. Unfortunately, little evidence is available, since many of these initiatives have not been appropriately assessed. Appropriate controlled assessments of the effect of youth-friendly health-service models on young people's health outcomes should be the focus of future research agendas. Enough is known to recommend that a priority for the future is to ensure that each country, state, and locality has a policy and support to encourage provision of innovative and well assessed youth-friendly services.

RESUMO

This document is the consensus of the American Association of Veterinary Laboratory Diagnosticians (AAVLD) Subcommittee on Standardization of Immunohistochemistry on a set of guidelines for immunohistochemistry (IHC) testing in veterinary laboratories. Immunohistochemistry is a powerful ancillary methodology frequently used in many veterinary laboratories for both diagnostic and research purposes. However, neither standardization nor validation of IHC tests has been completely achieved in veterinary medicine. This document addresses both issues. Topics covered include antibody selection, fixation, antigen retrieval, antibody incubation, antibody dilutions, tissue and reagent controls, buffers, and detection systems. The validation of an IHC test is addressed for both infectious diseases and neoplastic processes. In addition, storage and handling of IHC reagents, interpretation, quality control and assurance, and troubleshooting are also discussed. Proper standardization and validation of IHC will improve the quality of diagnostics in veterinary laboratories.

RESUMO

The susceptibility of wild ruminants, especially cervids, to bovine viral diarrhea virus (BVDV) has remained an enigma. Two white-tailed deer (Odocoileus virginianus) were submitted to the Animal Disease Research and Diagnostic Laboratory (ADRDL) in the fall of 2003 by the South Dakota Game Fish and Parks for chronic wasting disease (CWD) testing. Both animals were CWD negative. The animals were necropsied and histopathology, viral antigen detection, and virus isolation were performed. A noncytopathic (NCP) BVDV was isolated from the lungs and several other tissues of both animals. Formalin-fixed ear notches from both animals were positive for BVDV antigen by immunohistochemistry. The BVDV isolates were typed with the use of polymerase chain reaction in 5' untranslated region (UTR) and one isolate was typed a Type 2a and the other a Type 1b. Future field surveys to determine the incidence of BVDV along with experimental studies to determine if white-tailed deer fawns can be persistently infected with BVDV are needed.

RESUMO

BACKGROUND: There is international concern that conflicts of interest (COI) may bias clinical guideline development and render it untrustworthy. Guideline COI policies exist with the aim of reducing this bias but it is not known how such policies are interpreted and used by guideline producing organisations. This study sought to determine how conflicts of interest (COIs) are disclosed and managed by a national clinical guideline developer (NICE: the UK National Institute for Health and Care Excellence). METHODS: Qualitative study using semi-structured telephone interviews with 14 key informants: 8 senior staff of NICE's guideline development centres and 6 chairs of guideline development groups (GDGs). We conducted a thematic analysis. RESULTS: Participants regard the NICE COI policy as comprehensive leading to transparent and independent guidance. The application of the NICE COI policy is, however, not straightforward and clarity could be improved. Disclosure of COI relies on self reporting and guideline developers have to take "on trust" the information they receive, certain types of COI (non-financial) are difficult to categorise and manage and disclosed COI can impact on the ability to recruit clinical experts to GDGs. Participants considered it both disruptive and stressful to exclude members from GDG meetings when required by the COI policy. Nonetheless the impact of this disruption can be minimised with good group chairing skills. CONCLUSIONS: We consider that the successful implementation of a COI policy in clinical guideline development requires clear policies and procedures, appropriate training of GDG chairs and an evaluation of how the policy is used in practice.

RESUMO

Salt evaporation ponds have played an important role as habitat for migratory waterbirds across the world, however, efforts to restore and manage these habitats to maximize their conservation value has proven to be challenging. For example, salinity reduction has been a goal for restoring and managing former salt evaporation ponds to support waterbirds in the South Bay Salt Pond Restoration Project in San Francisco Bay, California, USA. Here, we describe a case study of unexpected consequences of a low-dissolved oxygen (DO) event on trophic interactions in a salt pond system following management actions to reduce salinity concentrations. We document the ramifications of an anoxic event in water quality including salinity, DO, and temperature, and in the response of the biota including prey fish biomass, numerical response by California Gulls (Larus californicus), and chick survival of Forster's Tern (Sterna forsteri). Management actions intended to protect receiving waters resulted in decreased DO concentrations that collapsed to zero for ≥ 4 consecutive days, resulting in an extensive fish kill. DO depletion likely resulted from an algal bloom that arose following transition of the pond system from high to low salinity as respiration and decomposition outpaced photosynthetic production. We measured a ≥ 6-fold increase in biomass of fish dropped on the levee by foraging avian predators compared with weeks prior to and following the low-DO event. California Gulls rapidly responded to the availability of aerobically-stressed and vulnerable fish and increased in abundance by two orders of magnitude. Mark-recapture analysis of 254 Forster's Tern chicks indicated that their survival declined substantially following the increase in gull abundance. Thus, management actions to reduce salinity concentrations resulted in cascading effects in trophic interactions that serves as a cautionary tale illustrating the importance of understanding the interaction of water quality and trophic structure when managing restoration of salt ponds.

RESUMO

A 2-year-old male Thoroughbred was evaluated for multiple firm, raised nodules of the maxilla and mandible that had been present since 6 months of age. The horse was evaluated as a yearling with a final histologic diagnosis of fibrosarcoma. As a 2-year-old, the colt made a loud upper airway sound and was agitated after strenuous exercise. Results of upper airway endoscopy indicated severe narrowing of the nasal passages and pharynx with normal resting function. Radiography revealed multiple circular bony lesions in the mandible, maxilla, multiple long bones, and cervical vertebrae. Biopsy specimens of the left mandible and right facial bone were obtained. A diagnosis of leiomyosarcoma with extensive metastatic bone formation was made on the basis of histologic features and the immunohistochemical staining properties of the biopsy specimens. Because of the diffuse distribution of the lesions, prognosis was guarded; 4 years after diagnosis, the horse had not pursued an athletic career.

RESUMO

OBJECTIVES: To develop user-generated quality standards for young people with mental health problems in primary care using a participatory research model. METHODS: 50 young people aged 16-25 from community settings and primary care participated in focus groups and interviews about their views and experiences of seeking help for mental health problems in primary care, cofacilitated by young service users and repeated to ensure respondent validation. A second group of young people also aged 16-25 who had sought help for any mental health problem from primary care or secondary care within the last 5 years were trained as focus groups cofacilitators (n=12) developed the quality standards from the qualitative data and participated in four nominal groups (n=28). RESULTS: 46 quality standards were developed and ranked by young service users. Agreement was defined as 100% of scores within a two-point region. Group consensus existed for 16 quality standards representing the following aspects of primary care: better advertising and information (three); improved competence through mental health training and skill mix within the practice (two); alternatives to medication (three); improved referral protocol (three); and specific questions and reassurances (five). Alternatives to medication and specific questions and reassurances are aspects of quality which have not been previously reported. CONCLUSIONS: We have demonstrated the feasibility of using participatory research methods in order to develop user-generated quality standards. The development of patient-generated quality standards may offer a more formal method of incorporating the views of service users into quality improvement initiatives. This method can be adapted for generating quality standards applicable to other patient groups.

RESUMO

Since the September 11, 2001, terrorist attacks, concern for the future direction of biological research has expanded to include not only issues involving the welfare of mankind, but also the more immediate and personal concern of individual scientists in the life sciences community. For many investigators in the life sciences, the remainder of their careers will be impacted by concerns about bioterrorism and issues associated with dual-use research. Awareness of these issues will be critical for all professional groups and affiliated organizations as they navigate the growing call for more federal rules and regulations. Veterinarians are not immune to the coming changes in science; all researchers risk criminal sanctions if they violate the USA Patriot Act or the Bioterrorism Act of 2002. Compliance with these regulations will be necessary, not just because of the potential legal ramifications, but because establishing and maintaining public trust is a never-ending requirement for the future of scientific research.
