RESUMO

Hypoxic ischaemic encephalopathy (HIE) is a major cause of neonatal mortality and disability in the United Kingdom (UK) and has significant human and financial costs. Therapeutic hypothermia (TH), which consists of cooling down the newborn's body temperature, is the current standard of treatment for moderate or severe cases of HIE. Timely initiation of treatment is critical to reduce risk of mortality and disability associated with HIE. Very expensive servo-controlled devices are currently used in high-income settings to induce TH, whereas low-income settings rely on the use of low-tech devices such as water bottles, ice packs or fans. Cooling mattresses made with phase change materials (PCMs) were recently developed as a safe, efficient, and affordable alternative to induce TH in low-income settings. This frugal innovation has the potential to become a reverse innovation for the National Health Service (NHS) by providing a simple, efficient, and cost-saving solution to initiate TH in geographically remote areas of the UK where cooling equipment might not be readily available, ensuring timely initiation of treatment while waiting for neonatal transport to the nearest cooling centre. The adoption of PCM cooling mattresses by the NHS may reduce geographical disparity in the availability of treatment for HIE in the UK, and it could benefit from improvements in coordination across all levels of neonatal care given challenges currently experienced by the NHS in terms of constraints on funding and shortage of staff. Trials evaluating the effectiveness and safety of PCM cooling mattresses in the NHS context are needed in support of the adoption of this frugal innovation. These findings may be relevant to other high-income settings that experience challenges with the provision of TH in geographically remote areas. The use of promising frugal innovations such as PCM cooling mattresses in high-income settings may also contribute to challenge the dominant narrative that often favours innovation from North America and Western Europe, and consequently fight bias against research and development from low-income settings, promoting a more equitable global innovation landscape.

RESUMO

BACKGROUND: Significant efforts have been made to develop artificial intelligence (AI) solutions for health care improvement. Despite the enthusiasm, health care professionals still struggle to implement AI in their daily practice. OBJECTIVE: This paper aims to identify the implementation frameworks used to understand the application of AI in health care practice. METHODS: A scoping review was conducted using the Cochrane, Evidence Based Medicine Reviews, Embase, MEDLINE, and PsycINFO databases to identify publications that reported frameworks, models, and theories concerning AI implementation in health care. This review focused on studies published in English and investigating AI implementation in health care since 2000. A total of 2541 unique publications were retrieved from the databases and screened on titles and abstracts by 2 independent reviewers. Selected articles were thematically analyzed against the Nilsen taxonomy of implementation frameworks, and the Greenhalgh framework for the nonadoption, abandonment, scale-up, spread, and sustainability (NASSS) of health care technologies. RESULTS: In total, 7 articles met all eligibility criteria for inclusion in the review, and 2 articles included formal frameworks that directly addressed AI implementation, whereas the other articles provided limited descriptions of elements influencing implementation. Collectively, the 7 articles identified elements that aligned with all the NASSS domains, but no single article comprehensively considered the factors known to influence technology implementation. New domains were identified, including dependency on data input and existing processes, shared decision-making, the role of human oversight, and ethics of population impact and inequality, suggesting that existing frameworks do not fully consider the unique needs of AI implementation. CONCLUSIONS: This literature review demonstrates that understanding how to implement AI in health care practice is still in its early stages of development. Our findings suggest that further research is needed to provide the knowledge necessary to develop implementation frameworks to guide the future implementation of AI in clinical practice and highlight the opportunity to draw on existing knowledge from the field of implementation science.

RESUMO

INTRODUCTION: Process mapping (PM) supports better understanding of complex systems and adaptation of improvement interventions to their local context. However, there is little research on its use in healthcare. This study (i) proposes a conceptual framework outlining quality criteria to guide the effective implementation, evaluation and reporting of PM in healthcare; (ii) reviews published PM cases to identify context and quality of PM application, and the reported benefits of using PM in healthcare. METHODS: We developed the conceptual framework by reviewing methodological guidance on PM and empirical literature on its use in healthcare improvement interventions. We conducted a systematic review of empirical literature using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology. Inclusion criteria were: full text empirical study; describing the process through which PM has been applied in a healthcare setting; published in English. Databases searched are: Medline, Embase, HMIC-Health Management Information Consortium, CINAHL-Cumulative Index to Nursing and Allied Health Literature, Scopus. Two independent reviewers extracted and analysed data. Each manuscript underwent line by line coding. The conceptual framework was used to evaluate adherence of empirical studies to the identified PM quality criteria. Context in which PM is used and benefits of using PM were coded using an inductive thematic analysis approach. RESULTS: The framework outlines quality criteria for each PM phase: (i) preparation, planning and process identification, (ii) data and information gathering, (iii) process map generation, (iv) analysis, (v) taking it forward. PM is used in a variety of settings and approaches to improvement. None of the reviewed studies (N = 105) met all ten quality criteria; 7% were compliant with 8/10 or 9/10 criteria. 45% of studies reported that PM was generated through multi-professional meetings and 15% reported patient involvement. Studies highlighted the value of PM in navigating the complexity characterising healthcare improvement interventions. CONCLUSION: The full potential of PM is inhibited by variance in reporting and poor adherence to underpinning principles. Greater rigour in the application of the method is required. We encourage the use and further development of the proposed framework to support training, application and reporting of PM. TRIAL REGISTRATION: Prospero ID: CRD42017082140.

RESUMO

BACKGROUND: Effective communication between pharmacists and patients is essential and improves health outcomes. Simulated patients (SPs) are trained to reproduce real-life situations and can help pharmacy students to develop and adapt their communication skills in a safe, learner-centred environment. The aim of this research was to explore how SP and pharmacy student role-play supports communication training. METHODS: A mixed methods realist evaluation approach was adopted to test an initial theory relating to SP role-play for pharmacy students. The intervention tested involved complex communication cases in a men's and women's health module in year three of a new MPharm programme. This SP session was the first such session, of the programme which exclusively focused on complex communication skills for the students. Data collected comprised video-recordings of both training and mock OSCE sessions, and from student focus groups. Communication videos were scored using the Explanation and Planning Scale (EPSCALE) tool. Scores from SP and mock OSCE sessions were compared using the Wilcoxon-signed rank test. Focus groups were conducted with students about their experience of the training and analysed thematically, through a realist lens. Data was analysed for Context-Mechanism-Outcome configurations to produce modified programme theories. RESULTS: Forty-six students (n = 46/59, 78 %) consented to their video-recorded interactions to be used. Students identified contextual factors relating to the timing within the course and the setting of the intervention, the debrief and student individual contexts. Mechanisms included authenticity, feedback, reflection, self-awareness and confidence. Negative responses included embarrassment and nervousness. They distinguished outcomes including increased awareness of communication style, more structured communication and increased comfort. However quantitative data showed a decrease (p < 0.001) in communication scores in the mock OSCE compared with scores from training sessions. Modified programme theories relating to SP training for pharmacy students were generated. CONCLUSIONS: SP role-play is a valuable communication skills training approach. Emphasis should be placed on multiple stakeholder feedback and promotion of reflection. Time limits need to be considered in this context and adjusted to meet student needs, especially for students with lower levels of communication comfort and those communicating in languages different to their first language.

RESUMO

Extemporaneous oral liquid preparations are commonly used when there is no commercially available dosage form for adjustable dosing. In most cases, there is a lack of stability data to allow for an accurately assigned shelf life and storage conditions to give greater confidence of product safety and efficacy over its shelf life. The aim of this study was to evaluate the physical, chemical and microbiological stability of an extemporaneous oral liquid suspension of losartan potassium, 5 mg/mL, used to treat paediatric hypertension in Our Lady's Children's Hospital Crumlin, Ireland. The losartan content of extemporaneous oral suspensions, prepared with and without addition of water, was measured by UV and confirmed by HPLC analysis. Suspensions were stored at 4 °C and room temperature (RT) and were monitored for changes in; pH, colour, odour, re-dispersibility, Total Aerobic Microbial Count, Total Yeast and Mould Count and absence of E. coli. Results showed that suspensions prepared by both methods, stored at 4 °C and RT, were physically and microbiologically stable over 28 days. Initial losartan content of all suspensions was lower than expected at 80-81% and did not change significantly over the 28 days. HPLC and NMR did not detect degradation of losartan in the samples. Suspensions prepared in water showed 100% losartan content. The reduced initial losartan content was confirmed by HPLC and was related to the acidic pH of the suspension vehicle. Physiochemical properties of the drug are important factors for consideration in the selection of suspension vehicle for extemporaneous compounding of oral suspensions as they can influence the quality, homogeneity and efficacy of these preparations.

RESUMO

Within this work, we describe the design and synthesis of a range of novel thiochromanones based on natural products reported to possess anti-leishmanial action, and their synthetic derivatives. All compounds were elaborated via the key intermediate 2,2,6-trimethoxythiochromanone, which was modified at the benzylic position to afford various ester, amine and amide analogues, substituted by chains of varying lipophilicity. Upon testing in Leishmania, IC50 values revealed the most potent compounds to be phenylalkenyl and haloalkyl amides 11a and 11e, with IC50 values of 10.5 and 7.2 µM, respectively.

RESUMO

Tetrastigma leucostaphylum (TL) is an important ethnic medicine of Bangladesh used to treat diarrhea and dysentery. Hence, current study has been designed to characterize the antidiarrheal (in vivo) and cytotoxic (in vitro) effects of T. leucostaphylum. A crude extract was prepared with methanol (MTL) and further partitioned into n-hexane (NTL), dichloromethane (DTL), and n-butanol (BTL) fractions. Antidiarrheal activity was investigated using castor oil induced diarrhea, enteropooling, and gastrointestinal transit models, while cytotoxicity was evaluated using the brine shrimp lethality bioassay. In antidiarrheal experiments, all doses (100, 200, and 400 mg/kg) of the DTL extract significantly reduced diarrheal stool frequency, volume and weight of intestinal contents, and gastrointestinal motility in mice. Similarly, in the cytotoxicity assay, all extracts exhibited activity, with the DTL extract the most potent (LC50 67.23 µg/mL). GC-MS analysis of the DTL extract identified 10 compounds, which showed good binding affinity toward M3 muscarinic acetylcholine, 5-HT3, Gut inhibitory phosphodiesterase, DNA polymerase III subunit alpha, and UDP-N-acetylglucosamine-1 carboxyvinyltransferase enzyme targets upon molecular docking analysis. Although ADME/T analyses predicted the drug-likeness and likely safety upon consumption of these bioactive compounds, significant toxicity concerns are evident due to the presence of the known phytotoxin, 2,4-di-tert-butylphenol. In summary, T. leucostaphylum showed promising activity, helping to rationalize the ethnomedicinal use and importance of this plant, its safety profile following both acute and chronic exposure warrants further investigation.

RESUMO

When there is significant uncertainty in an innovation project, research literature suggests that strictly sequencing actions and stages may not be an appropriate mode of project management. We use a longitudinal process approach and qualitative system dynamics modelling to study the development of genetically modified (GM) mosquitoes for malaria eradication in an African country. Our data were collected in real time, from early scientific research to deployment of the first prototype mosquitoes in the field. The 'gene drive' technology for modifying the mosquitoes is highly complex and controversial due to risks associated with its characteristics as a living, self-replicating technology. We show that in this case the innovation journey is linear and highly structured, but also embedded within a wider system of adoption that displays emergent behaviour. Although the need to control risks associated with the technology imposes a linearity to the NPD process, there are possibilities for deviation from a more structured sequence of stages. This arises from the effects of feedback loops in the wider system of evidence creation and learning at the population and governance levels, which cumulatively impact on acceptance of the innovation. The NPD and adoption processes are therefore closely intertwined, meaning that the endpoint for R&D and beginning of 'mainstream' adoption and diffusion are unclear. A key challenge for those responsible for NPD and its regulation is to plan for the adoption of the technology while simultaneously conducting its scientific and technical development.

RESUMO

BACKGROUND: Umbilical cord blood (UCB) has become an important source of transplantable CD34+ hematopoietic progenitor cells. Cord blood banks (CBBs) can increase their efficiency by minimizing the processing of UCB units with low CD34+ content, which have a lower likelihood of transplant utilization. We sought to identify a readily available preprocessing metric that would correlate with CD34+ cell counts, without the cost of additional analysis. STUDY DESIGN AND METHODS: Data were compiled for 131 UCB units processed at the regional CBB. Preprocessing hematologic metrics, including complete blood count and differential, were compared to postprocessing CD34+ cell quantities. The data were divided into six groups of varying preprocessing metrics, then compared for significant differences in postprocessing CD34+ cell quantities to develop a screening guidance. RESULTS: UCB units with nucleated RBC (nRBC) content of 15% or greater were found to have a significant increase in CD34+ cell percentage (p < 0.00001) and total CD34+ cell content (p < 0.0001). Units with preprocessing total nucleated cell count (TNC) of ≥ 1.50 × 109 with nRBC content of 15% or greater, and for TNC ≥ of 2.00 × 109 with nRBC content less than15%, had a significant increase in CD34+ content (p < 0.05 and p < 0.001, respectively). Applied as a screening guideline, these units had an increase in mean CD34+ content from 6.24 × 106 to 9.27 × 106 . Units originally in the bottom and top quartiles of CD34+ content constitute 5% and 53% of processed units meeting these TNC/nRBC criteria, respectively. CONCLUSION: These screening criteria utilizing nRBC provides a guideline that public CBBs may use to increase their efficiency by minimizing the processing of UCB units with lower CD34+ cell content.

RESUMO

Background This study aimed to develop the Point-of-Care Key Evidence Tool (POCKET); a multi-dimensional checklist to guide the evaluation of point-of-care tests (POCTs) incorporating validity, utility, usability, cost-effectiveness and patient experience. The motivation for this was to improve the efficiency of evidence generation in POCTs and reduce the lead-time for the adoption of novel POCTs. Methods A mixed qualitative and quantitative approach was applied. Following a literature search, a three round Delphi process was undertaken incorporating a semi-structured interview study and two questionnaire rounds. Participants included clinicians, laboratory personnel, commissioners, regulators (including members of National Institute for Health and Care Excellence [NICE] committees), patients, industry representatives and methodologists. Qualitative data were analysed based on grounded theory. The final tool was revised at an expert stakeholder workshop. Results Forty-three participants were interviewed within the semi-structured interview study, 32 participated in the questionnaire rounds and nine stakeholders attended the expert workshop. The final version of the POCKET checklist contains 65 different evidence requirements grouped into seven themes. Face validity, content validity and usability has been demonstrated. There exists a shortfall in the evidence that industry and research methodologists believe should be generated regarding POCTs and what is actually required by policy and decision makers to promote implementation into current healthcare pathways. Conclusions This study has led to the development of POCKET, a checklist for evidence generation and synthesis in POCTs. This aims to guide industry and researchers to the evidence that is required by decision makers to facilitate POCT adoption so that the benefits they can bring to patients can be effectively realised.

RESUMO

Ophiorrhiza rugosa var. prostrata is one of the most frequently used ethnomedicinal plants by the indigenous communities of Bangladesh. This study was designed to investigate the antidiarrheal, anti-inflammatory, anthelmintic and antibacterial activities of the ethanol extract of O. rugosa leaves (EEOR). The leaves were extracted with ethanol and subjected to in vivo antidiarrheal screening using the castor oil-induced diarrhea, enteropooling, and gastrointestinal transit models. Anti-inflammatory efficacy was evaluated using the histamine-induced paw edema test. In parallel, in vitro anthelmintic and antibacterial activities were evaluated using the aquatic worm and disc diffusion assays respectively. In all three diarrheal models, EEOR (100, 200 and 400 mg/kg) showed obvious inhibition of diarrheal stool frequency, reduction of the volume and weight of the intestinal contents, and significant inhibition of intestinal motility. Also, EEOR manifested dose-dependent anti-inflammatory activity. Anthelmintic action was deemed significant (P < 0.001) with respect to the onset of paralysis and helminth death. EEOR also resulted in strong zones of inhibition when tested against both Gram-positive and Gram-negative bacteria. GC-MS analysis identified 30 compounds within EEOR, and of these, 13 compounds documented as bioactive showed good binding affinities to M3 muscarinic acetylcholine, 5-HT3, tubulin and GlcN-6-P synthase protein targets in molecular docking experiments. Additionally, ADME/T and PASS analyses revealed their drug-likeness, likely safety upon consumption and possible pharmacological activities. In conclusion, our findings scientifically support the ethnomedicinal use and value of this plant, which may provide a potential source for future development of medicines.

RESUMO

Improving the quality of healthcare involves collaboration between many different stakeholders. Collaborative learning theory suggests that teaching different professional groups alongside each other may enable them to develop skills in how to collaborate effectively, but there is little literature on how this works in practice. Further, though it is recognised that patients play a fundamental role in quality improvement, there are few examples of where they learn together with professionals. To contribute to addressing this gap, we review a collaborative fellowship in Northwest London, designed to build capacity to improve healthcare, which enabled patients and professionals to learn together. Using the lens of collaborative learning, we conducted an exploratory study of six cohorts of the year long programme (71 participants). Data were collected using open text responses from an online survey (n = 31) and semi-structured interviews (n = 34) and analysed using an inductive open coding approach. The collaborative design of the Fellowship, which included bringing multiple perspectives to discussions of real world problems, was valued by participants who reflected on the safe, egalitarian space created by the programme. Participants (healthcare professionals and patients) found this way of learning initially challenging yet ultimately productive. Despite the pedagogical and practical challenges of developing a collaborative programme, this study indicates that opening up previously restricted learning opportunities as widely as possible, to include patients and carers, is an effective mechanism to develop collaborative skills for quality improvement.

RESUMO

Calea uniflora Less. is widely used in southern Santa Catarina (Brazil), but there are no scientific studies which support its use. Then, this study was proposed to determine of the percentage use of C. uniflora in a city of southern Brazil and documentation of the knowledge that the population has about this species. The survey was conducted with semi-structured interviews using a questionnaire applied to 372 participants. In analyzing the results, it was observed that of the 94.1% who recognized C. uniflora, 74.3% utilize it as a medicinal plant and 65.4% of such knowledge originates in childhood, mainly through the family (84.6%). 93% reported using inflorescences macerated in alcohol or rum; this extract is generally used topically for wound healing and muscle pain. Furthermore, some reported using small quantities of this extract orally to treat cold and flu. Regarding effectiveness and safety, 97% stated an improvement in symptoms with the use of the plant, while 98.5% stated that it has no toxicity. In light of these results, future phytochemical, pharmacological and toxicological analyses should be designed in order to ensure rational and safe use of this species.

RESUMO

BACKGROUND AND OBJECTIVES: Patient and public involvement (PPI) is seen as a way of helping to shape health policy and ensure a patient-focused health-care system. While evidence indicates that PPI can improve health-care decision making, it also consumes monetary and non-monetary resources. Given the financial climate, it is important to start thinking about the costs and benefits of PPI and how to evaluate it in economic terms. DESIGN: We conducted a literature review to assess the potential benefits and costs of involvement and the challenges in carrying out an economic evaluation of PPI. RESULTS: The benefits of PPI include effects on the design of new projects or services, on NHS governance, on research design and implementation and on citizenship and equity. Economic evaluation of PPI activities is limited. The lack of an appropriate analytical framework, data recording and understanding of the potential costs and benefits of PPI, especially from participants' perspectives, represent serious constraints on the full evaluation of PPI. CONCLUSIONS: By recognizing the value of PPI, health-care providers and commissioners can embed it more effectively within their organizations. Better knowledge of costs may prompt organizations to effectively plan, execute, evaluate and target resources. This should increase the likelihood of more meaningful activity, avoid tokenism and enhance organizational efficiency and reputation.

RESUMO

BACKGROUND: Joint consultations - such as teleconsultations - provide opportunities for continuing education of general practitioners (GPs). It has been reported this form of interactive case-based learning may lead to fewer GP referrals, yet these studies have relied on expert opinion and simple frequencies, without accounting for other factors known to influence referrals. We use a survey-based discrete choice experiment of GPs' referral preferences to estimate how referral rates are associated with participation in joint teleconsultations, explicitly controlling for a number of potentially confounding variables. METHODS: We distributed questionnaires at two meetings of the Portuguese Association of General Practice. GPs were presented with descriptions of patients with dermatological lesions and asked whether they would refer based on the waiting time, the distance to appointment, and pressure from patients for a referral. We analysed GPs' responses to multiple combinations of these factors, coupled with information on GP and practice characteristics, using a binary logit model. We estimated the probabilities of referral of different lesions using marginal effects. RESULTS: Questionnaires were returned by 44 GPs, giving a total of 721 referral choices. The average referral rate for the 11 GPs (25%) who had participated in teleconsultations was 68.1% (range 53-88%), compared to 74.4% (range 47-100%) for the remaining physicians. Participation in teleconsultations was associated with reductions in the probabilities of referral of 17.6% for patients presenting with keratosis (p = 0.02), 42.3% for psoriasis (p < 0.001), 8.4% for melanoma (p = 0.14), and 5.4% for naevus (p = 0.19). CONCLUSIONS: The results indicate that GP participation in teleconsultations is associated with overall reductions in referral rates and in variation across GPs, and that these effects are robust to the inclusion of other factors known to influence referrals. The reduction in range, coupled with different effects for different clinical presentations, may suggest an educational effect. However, more research is needed to establish whether there are causal relationships between participation in teleconsultations, continuing education, and referral rates.

RESUMO

Carriers are often an essential element of drug delivery, bestowing attributes to their cargo such as biocompatibility, enhanced delivery, extended half-life and efficacy as well as mediating specific targeting at a tissue, cell or intracellular level. Liposomes and lipid-based carriers have been investigated for decades for this purpose, many achieving clinical approval including products such as Doxil® and Myocet™. Large-scale compound screens are routinely carried out in the field of drug discovery; however, less work has been done on harnessing high-throughput methods for carrier material screening. Screening the interaction of drug carriers and materials with cells is particularly critical for the development of emerging therapies, including biomedicines, in order to facilitate the development of safe and efficient drug products. Herein, a range of liposomes of neutral, anionic and cationic charge and others that are surface-modified with mannose residues were screened for cell interaction, toxicity and immune reactivity in THP-1-derived macrophages using a high-throughput format. Liposomes were seen to be efficacious in a concentration-dependent and, for mannosylated liposomes, mannosylated cholesterol linker length-dependent manner.

RESUMO

Calls for successful knowledge translation (KT) in health care have multiplied over recent years. The National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) program is a policy initiative in the United Kingdom aimed at speeding-up the translation of research into health care practice. Using multiple qualitative research methods and drawing on the ongoing processes used by individuals to interpret and contextualize information, we explore how new organizational forms for KT bridge the gap between research and practice. We pay particular attention to the relationship between the organization and practices of KT and leadership. Our empirical data demonstrate how the relationship between leadership and KT shifted over time from a push model where the authoritarian top-down leadership team set outcome measures by which to judge KT performance to one which aimed to distribute leadership capacity across a wide range of stakeholders in health and social care systems. The relationship between the organization and practices of KT and leadership is affected by local contextual influences on policies directed at increasing the uptake of research in clinical practice. Policy makers and service leaders need to recognize that more dispersed type of leadership is needed to accommodate the idiosyncratic nature of collective action.

RESUMO

PURPOSE OF THE STUDY: to examine the costs and cost-effectiveness of 'second-generation' telecare, in addition to standard support and care that could include 'first-generation' forms of telecare, compared with standard support and care that could include 'first-generation' forms of telecare. DESIGN AND METHODS: a pragmatic cluster-randomised controlled trial with nested economic evaluation. A total of 2,600 people with social care needs participated in a trial of community-based telecare in three English local authority areas. In the Whole Systems Demonstrator Telecare Questionnaire Study, 550 participants were randomised to intervention and 639 to control. Participants who were offered the telecare intervention received a package of equipment and monitoring services for 12 months, additional to their standard health and social care services. The control group received usual health and social care. PRIMARY OUTCOME MEASURE: incremental cost per quality-adjusted life year (QALY) gained. The analyses took a health and social care perspective. RESULTS: cost per additional QALY was £297,000. Cost-effectiveness acceptability curves indicated that the probability of cost-effectiveness at a willingness-to-pay of £30,000 per QALY gained was only 16%. Sensitivity analyses combining variations in equipment price and support cost parameters yielded a cost-effectiveness ratio of £161,000 per QALY. IMPLICATIONS: while QALY gain in the intervention group was similar to that for controls, social and health services costs were higher. Second-generation telecare did not appear to be a cost-effective addition to usual care, assuming a commonly accepted willingness to pay for QALYs. TRIAL REGISTRATION NUMBER: ISRCTN 43002091.

RESUMO

Alentejo covers a third of Portugal, yet it is home to only 5% of the population. Residents of the region are poorer, older, and less educated than the rest of the country. There is a shortage of physicians in several specialties. The low population density, a concentration of specialized services, and a poor public transportation network all create barriers to access. Telemedicine was introduced in 1998 to help address these challenges. In this article, we provide an overview of the program and its current status, focusing on infrastructure, services, and activity volume. We also discuss the impact the program has had from the perspectives of patients and healthcare professionals. From 1998 to 2011, there were 132,546 episodes of service using telemedicine, including real-time teleconsultations, teleradiology, teleultrasound, and telepathology. At present, the network includes 20 primary care units and five hospitals, covering almost 30,000 km(2) and 500,000 people. Units have high-resolution videoconferencing equipment, access to patients' clinical records, an image archive, and peripherals, such as electronic dermatoscopes and phonendoscopes. Teleconsultations are available in 15 medical specialties and areas, ranging from neurology to pediatric surgery. In 2008, regional health authorities started a tele-education program, and by the end of 2011, 876 healthcare professionals, across 52 locations, had participated in remote learning sessions. More than a decade since telemedicine was introduced in Alentejo, it is now an integral part of everyday service provision. A comprehensive assessment of the costs and consequences of the program is currently underway.

RESUMO

Ethics is a core component of healthcare curricula and may provide ideal content for interprofessional education (IPE). An IPE debate in ethics and professionalism was developed for first year undergraduate pharmacy and physiotherapy students. A controlled "before-and-after" study was conducted. The opinion of students on IPE, the debate topics and debating was determined before and after the debate. While there was no impact on attitudes to IPE or healthcare professionals, students agreed that debating ethics through IPE was a valid teaching modality. Students found the debates challenging. They stimulated critical thinking and interest in complex and controversial issues. Students also found it of benefit to work as a team. We conclude that in-class debate is a useful way of learning together.
