RESUMO

Auctions have attracted growing attention as bidding mechanisms for soliciting or allocating payments for a wide range of ecosystem services (ES). This paper reviews the latest scientific knowledge on ES auctioning approaches. Using systematically selected academic articles, we trace and discuss the development of ES auction literature across space, time, target ecosystem, and mechanism type. We integrate previous attempts to organize this body of work to produce a composite factor map of entry points to more specialized sub-literatures engaging with current issues in auction design and implementation. The results show that most academic work focuses on reverse auctions, where landowners bid their willingness to accept contracts to protect or promote ES provisioning, but we also locate several forward (i.e. beneficiaries bid their willingness to pay for ES) and mixed mechanisms. We critically analyze major advantages and challenges for each approach, emphasizing issues related to transaction costs and accessibility for participants and agencies. Overall, our findings suggest that ES auctions have a robust track record but remain administratively and logistically challenging. Further investment in open-source tools, shared infrastructure, and other efforts to make auctions more accessible to researchers, agencies, and participants alike is strongly indicated.

RESUMO

BACKGROUND: Telephone therapist delivered CBT (TCBT) and web-based CBT (WCBT) have been shown to be significantly more clinically effective than treatment as usual (TAU) at reducing IBS symptom severity and impact at 12 months in adults with refractory IBS. In this paper we assess the cost-effectiveness of the interventions. METHODS: Participants were recruited from 74 general practices and three gastroenterology centres in England. Interventions costs were calculated, and other service use and lost employment measured and costed for one-year post randomisation. Quality-adjusted life years (QALYs) were combined with costs to determine cost-effectiveness of TCBT and WCBT compared to TAU. RESULTS: TCBT cost £956 more than TAU (95% CI, £601-£1435) and generated 0.0429 more QALYs. WCBT cost £224 more than TAU (95% CI, - £11 to £448) and produced 0.029 more QALYs. Compared to TAU, TCBT had an incremental cost per QALY of £22,284 while the figure for WCBT was £7724. After multiple imputation these ratios increased to £27,436 and £17,388 respectively. Including lost employment and informal care, TCBT had costs that were on average £866 lower than TAU (95% CI, - £1133 to £2957), and WCBT had costs that were £1028 lower than TAU (95% CI, - £448 to £2580). CONCLUSIONS: TCBT and WCBT resulted in more QALYs and higher costs than TAU. Complete case analysis suggests both therapies are cost-effective from a healthcare perspective. Imputation for missing data reduces cost-effectiveness but WCTB remained cost-effective. If the reduced societal costs are included both interventions are likely to be more cost-effective.

RESUMO

BACKGROUND: Irritable bowel syndrome (IBS) affects 10-22% of people in the UK. Abdominal pain, bloating and altered bowel habits affect quality of life and can lead to time off work. Current treatment relies on a positive diagnosis, reassurance, lifestyle advice and drug therapies, but many people suffer ongoing symptoms. Cognitive-behavioural therapy (CBT) is recommended in guidelines for patients with ongoing symptoms but its availability is limited. OBJECTIVES: To determine the clinical effectiveness and cost-effectiveness of therapist telephone-delivered CBT (TCBT) and web-based CBT (WCBT) with minimal therapist support compared with treatment as usual (TAU) in refractory IBS. DESIGN: This was a three-arm randomised controlled trial. SETTING: This trial took place in UK primary and secondary care. PARTICIPANTS: Adults with refractory IBS (clinically significant symptoms for 12 months despite first-line therapies) were recruited from 74 general practices and three gastroenterology centres from May 2014 to March 2016. INTERVENTIONS: TCBT - patient CBT self-management manual, six 60-minute telephone sessions over 9 weeks and two 60-minute booster sessions at 4 and 8 months (8 hours' therapist time). WCBT - interactive, tailored web-based CBT, three 30-minute telephone sessions over 9 weeks and two 30-minute boosters at 4 and 8 months (2.5 hours' therapist time). MAIN OUTCOME MEASURES: Primary outcomes - IBS symptom severity score (IBS SSS) and Work and Social Adjustment Scale (WSAS) at 12 months. Cost-effectiveness [quality-adjusted life-years (QALYs) and health-care costs]. RESULTS: In total, 558 out of 1452 patients (38.4%) screened for eligibility were recruited - 186 were randomised to TCBT, 185 were randomised to WCBT and 187 were randomised to TAU. The mean baseline Irritable Bowel Syndrome Symptom Severity Score (IBS SSS) was 265.0. An intention-to-treat analysis with multiple imputation was carried out at 12 months; IBS SSS were 61.6 points lower in the TCBT arm [95% confidence interval (CI) 89.5 to 33.8; p < 0.001] and 35.2 points lower in the WCBT arm (95% CI 57.8 to 12.6; p = 0.002) than in the TAU arm (IBS SSS of 205.6). The mean WSAS score at 12 months was 10.8 in the TAU arm, 3.5 points lower in the TCBT arm (95% CI 5.1 to 1.9; p < 0.001) and 3.0 points lower in the WCBT arm (95% CI 4.6 to 1.3; p = 0.001). For the secondary outcomes, the Subject's Global Assessment showed an improvement in symptoms at 12 months (responders) in 84.8% of the TCBT arm compared with 41.7% of the TAU arm [odds ratio (OR) 6.1, 95% CI 2.5 to 15.0; p < 0.001] and 75.0% of the WCBT arm (OR 3.6, 95% CI 2.0 to 6.3; p < 0.001). Patient enablement was 78.3% (responders) for TCBT, 23.5% for TAU (OR 9.3, 95% CI 4.5 to 19.3; p < 0.001) and 54.8% for WCBT (OR 3.5, 95% CI 2.0 to 5.9; p < 0.001). Adverse events were similar between the trial arms. The incremental cost-effectiveness ratio (ICER) (QALY) for TCBT versus TAU was £22,284 and for WCBT versus TAU was £7724. Cost-effectiveness reduced after imputation for missing values. Qualitative findings highlighted that, in the CBT arms, there was increased capacity to cope with symptoms, negative emotions and challenges of daily life. Therapist input was important in supporting WCBT. CONCLUSIONS: In this large, rigorously conducted RCT, both CBT arms showed significant improvements in IBS outcomes compared with TAU. WCBT had lower costs per QALY than TCBT. Sustained improvements in IBS symptoms are possible at an acceptable cost. Suggested future research work is longer-term follow-up and research to translate these findings into usual clinical practice. FUTURE WORK: Longer-term follow-up and research to translate these findings into usual clinical practice is needed. TRIAL REGISTRATION: Current Controlled Trials ISRCTN44427879. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme and will be published in full in Health Technology Assessment; Vol. 23, No. 17. See the NIHR Journals Library website for further project information. The University of Southampton sponsored this study. Funding was received from the NIHR HTA Board and the NIHR Clinical Research Network and support was received from the NIHR Clinical Research Network.


Irritable bowel syndrome (IBS) is a common bowel disorder causing pain, bloating and diarrhoea or constipation, which can affect quality of life. Treatment relies on a positive diagnosis, reassurance, lifestyle advice and drug therapies. However, many patients suffer ongoing distressing symptoms. Guidelines recommend cognitive­behavioural therapy (CBT) for patients with ongoing IBS symptoms. However, access to therapy is limited because of cost and therapist availability. We previously developed web-based CBT (WCBT), which is more accessible, less expensive and requires less therapist time than traditional therapist telephone-delivered CBT (TCBT). The aim of the current trial was to assess the clinical effectiveness and cost-effectiveness of these two approaches. Participants were randomly assigned to TCBT, WCBT or treatment as usual (TAU). The TCBT group received a CBT manual and six 1-hour telephone CBT sessions with trained therapists over 9 weeks and two booster sessions at 4 and 8 months. The WCBT group received access to the interactive CBT website with eight online sessions at home over 9 weeks, with similar content to the therapist CBT, and received three 30-minute therapist telephone-delivered CBT sessions and two boosters at 4 and 8 months. There were 558 adults with ongoing IBS symptoms who took part from 74 general practice surgeries and three hospital clinics in London and the south of England. The main study outcomes were the IBS Symptom Severity Score and the Work and Social Adjustment Scale, which measures people's ability to function and live their lives. The results of these were collected at the start of the study and at 3, 6 and 12 months. Significant improvement in symptoms was found in the two therapy groups compared with TAU at 3, 6 and 12 months. Cost-effectiveness and wider benefits (e.g. ability to cope and mood) also showed positive results, indicating that sustained improvements in IBS symptoms are possible at an acceptable cost.

RESUMO

This chapter compares the conceptual foundations of health literacy and health disparities. It details some of the conceptual differences between health literacy and health disparities and explains some similarities that suggest the need for increased research collaboration. The chapter is among the first to address the structural and social determinants of health together and explain that future research needs to assess their interactions. Overall, the chapter creates a conceptual foundation as well as challenges future scholars/practitioners to take more multidimensional approaches to assess health's determinants. The chapter also attempts to demonstrate there is nothing more practical than good theory, or clear conceptual foundations. The chapter is divided into four sections that address the following topics: three conceptual frameworks about the determinants of health; opportunities in health disparities and health literacy research; seeking an expanded, multidimensional conceptual approach to health literacy and health disparities research; as well as a conclusion. The chapter suggests there are vacuums in current research knowledge that need future attention - especially regarding the integration of health literacy and health disparities research.

RESUMO

INTRODUCTION: Irritable bowel syndrome (IBS) affects 10-22% of the UK population, with England's annual National Health Service (NHS) costs amounting to more than £200 million. Abdominal pain, bloating and altered bowel habit affect quality of life, social functioning and time off work. Current treatment relies on a positive diagnosis, reassurance, lifestyle advice and drug therapies, but many people suffer ongoing symptoms. Cognitive behaviour therapy (CBT) and self-management can be helpful, but availability is limited. METHODS AND ANALYSIS: To determine the clinical- and cost-effectiveness of therapist delivered cognitive behavioural therapy (TCBT) and web-based CBT self-management (WBCBT) in IBS, 495 participants with refractory IBS will be randomised to TCBT plus treatment as usual (TAU); WBCBT plus TAU; or TAU alone. The two CBT programmes have similar content. However, TCBT consists of six, 60 min telephone CBT sessions with a therapist over 9 weeks, at home, and two 'booster' 1 hour follow-up phone calls at 4 and 8 months (8 h therapist contact time). WBCBT consists of access to a previously developed and piloted WBCBT management programme (Regul8) and three 30 min therapist telephone sessions over 9 weeks, at home, and two 'booster' 30 min follow-up phone calls at 4 and 8 months (2½â€…h therapist contact time). Clinical effectiveness will be assessed by examining the difference between arms in the IBS Symptom Severity Score (IBS SSS) and Work and Social Adjustment Scale (WASAS) at 12 months from randomisation. Cost-effectiveness will combine measures of resource use with the IBS SSS at 12 months and quality-adjusted life years. ETHICS AND DISSEMINATION: This trial has full ethical approval. It will be disseminated via peer reviewed publications and conference presentations. The results will enable clinicians, patients and health service planners to make informed decisions regarding the management of IBS with CBT. TRIAL REGISTRATION NUMBER: ISRCTN44427879.

RESUMO

As the emphasis on individuals' active partnership in health care grows, so does the public's need for effective, comprehensible consumer health resources. Consumer health informatics has the potential to provide frameworks and strategies for designing effective health communication tools that empower users and improve their health decisions. This article presents an overview of the consumer health informatics field, discusses promising approaches to supporting health communication, and identifies challenges plus direction for future research and development. The authors' recommendations emphasize the need for drawing upon communication and social science theories of information behavior, reaching out to consumers via a range of traditional and novel formats, gaining better understanding of the public's health information needs, and developing informatics solutions for tailoring resources to users' needs and competencies. This article was written as a scholarly outreach and leadership project by members of the American Medical Informatics Association's Consumer Health Informatics Working Group.

RESUMO

OBJECTIVES: Overcoming health disparities between majority and minority populations is a significant national challenge. This paper assesses outreach to Native Americans (American Indians, Alaska Natives, and Native Hawaiians) by the National Library of Medicine (NLM). A companion paper details NLM's portfolio of Native American outreach projects. METHOD: NLM's Native American outreach is assessed in light of the presentations at a community-based health information outreach symposium and the goals set by NLM's plan to reduce health disparities. RESULTS: NLM's current portfolio of Native American outreach projects appears most advanced in meeting the goal set in area 1 of the health disparities plan, "Promote use of health information by health professionals and the public." NLM's portfolio also shows significant strength and good progress regarding area 2 of the plan, "Expand partnerships among various types of libraries and community-based organizations." The portfolio is weaker in area 3, "Conduct and support informatics research." More knowledge-building efforts would benefit NLM, the National Network of Libraries of Medicine, and Native American and community-based organizations. IMPLICATIONS: The current Native American outreach portfolio should be continued, but new approaches are needed for evaluating Native American outreach and for forging collaborations with Native American groups, approaches grounded in consultation and mutual understanding of needs and perspectives.
