Young people's views on the acceptability and feasibility of loneliness interventions for their age group.

BACKGROUND: Loneliness is a frequently reported problem for young people aged 16 to 24 years old. A variety of interventions have been developed (but in most cases not extensively evaluated) to try and tackle loneliness in this age group. These include interpersonal, intrapersonal, and social approaches that vary in their content and mechanisms of action. The current study aimed to qualitatively examine young peoples' views on the acceptability and feasibility of different loneliness interventions. METHODS: Young people from 16 to 24 years old living in the United Kingdom who self-identified as having experienced loneliness were recruited to participate in this study. We conducted semi-structured qualitative interviews to assess their views on the acceptability and feasibility of loneliness interventions for their age group. Interviews were analysed using inductive reflexive thematic analysis. RESULTS: Our analysis of 23 individual interview transcripts identified six themes. These related to the appropriate stage for intervention and how different types of strategies may be best suited to particular contexts; the key facilitators and barriers to engaging young people in an intervention; considerations for optimising the delivery of an intervention; divergent views on technology use in strategies to manage loneliness; the scope of an intervention and whether it takes a targeted or general approach; and the idea of combining different options within an intervention to allow tailoring to individual preferences and nature of loneliness. CONCLUSIONS: These findings demonstrate the need for continued development of individualised interventions designed to help manage loneliness in this age group. Future loneliness strategies should be co-produced with young people to ensure that they suit the varying needs of this population.

The economic value of personal protective equipment for healthcare workers.

In this paper, we examine the cost effectiveness of investment in personal protective equipment (PPE) for protecting health care workers (HCWs) against two infectious diseases: Ebola virus and methicillin-resistant Staphylococcus aureus (MRSA). This builds on similar work published for COVID-19 in 2020. We developed two separate decision-analytic models using a payer perspective to compare the costs and effects of multiple PPE use scenarios for protection of HCW against Ebola and MRSA. Bayesian multivariate sensitivity analyses were used to consider the uncertainty surrounding all key parameters for both diseases. We estimate the cost to provide adequate PPE for a HCW encounter with an Ebola patient is $13.04, which is associated with a 97% risk reduction in infections. The mean incremental cost-effectiveness ratio (ICER) is $3.98 per disability-adjusted life year (DALY) averted. Because of lowered infection and disability rates, this investment is estimated to save $132.27 in averted health systems costs, a financial ROI of 1,014%. For MRSA, the cost of adequate PPE for one HCW encounter is $0.88, which is associated with a 53% risk reduction in infections. The mean ICER is $362.14 per DALY averted. This investment is estimated to save $20.18 in averted health systems costs, a financial ROI of 2,294%. In terms of total health savings per death averted, investing in adequate PPE is the dominant strategy for Ebola and MRSA, suggesting that it is both more costly and less clinically optimal to not fully invest in PPE for these diseases. There are many compelling reasons to invest in PPE to protect HCWs. This analysis examines the economic case, building on previous evidence that protecting HCWs with PPE is cost-effective for COVD-19. Ebola and MRSA scenarios were selected to allow assessment of both endemic and epidemic infectious diseases. While PPE is cost-effective for both conditions, compared to our analysis for COVID-19, PPE is relatively more cost-effective for Ebola and relatively less so for MRSA. Further research is needed to assess shortfalls in the PPE supply chain identified during the COVID-19 pandemic to ensure an efficient and resilient supply in the face of future pandemics.

Existing gaps and missed opportunities in delivering quality nutrition services in primary healthcare: a descriptive analysis of patient experience and provider competence in 11 low-income and middle-income countries.

OBJECTIVES: To assess the competence of primary healthcare (PHC) providers in delivering maternal and child nutrition services at the PHC level and patients' experience in receiving the recommended components of care. DESIGN: Observational cross-sectional analysis. SETTING: Healthcare facilities in low/middle-income countries (LMICs) with available service provision assessment surveys (Afghanistan (2018), Democratic Republic of Congo (2018), Haiti (2017), Kenya (2010), Malawi (2013-2014), Namibia (2009), Nepal (2015), Rwanda (2007), Senegal (2018), Tanzania (2015) and Uganda (2007). PARTICIPANTS: 18 644 antenatal visits and 23 262 sick child visits in 8458 facilities across 130 subnational areas in 11 LMICs from 2007 to 2019. OUTCOMES: (1) Provider competence assessed as the direct observations of actions performed during antenatal care (ANC) and sick child visits; and (2) patients' experience defined as the self-reported awareness of the nutrition services received during ANC and sick child visits and provider effectiveness in delivering these services. RESULTS: Except for DRC, all countries scored below 50% on patients' experience and provider competence. More than 70% of clients were advised on taking iron supplements during pregnancy; however, less than 32% of patients were advised on iron side effects in all the studied countries. Across all countries, providers commonly took anthropometric measurements of expectant mothers and children; however, such assessments were rarely followed up with advice or counselling about growth patterns. In addition, less than 20% of observed providers advised on early/immediate breast feeding in all countries with available data. CONCLUSION: The 11 assessed countries demonstrated the delivery of limited nutrition services; nonetheless, the apparent deficiency in the extent and depth of questions asked for the majority of tracer activities revealed significant opportunities for improving the quality of nutrition service delivery at the PHC level.

Capacity and quality of maternal and child health services delivery at the subnational primary healthcare level in relation to intermediate health outputs: a cross-sectional study of 12 low-income and middle-income countries.

OBJECTIVES: To examine the capacity and quality of maternal and child health (MCH) services at the subnational primary healthcare (PHC) level in 12 low-income and middle-income countries (LMICs) and its association with intermediate health outputs such as coverage and access to care. DESIGN: Observational cross-sectional study using matched subnational data from service provision assessment surveys and demographic health surveys from 2007 to 2019. SETTINGS: 138 subnational areas with available survey data in 12 LMICs (Afghanistan, Bangladesh, Democratic Republic of Congo, Haiti, Kenya, Malawi, Namibia, Nepal, Rwanda, Senegal, Tanzania and Uganda). OUTCOMES: Eight intermediate MCH outcomes/outputs were explored: (1) met need for family planning by modern methods; (2) attendance of four or more antenatal care visits; (3) perceived financial barriers to care; (4) perceived geographical barriers to care; (5) diphtheria-pertussis-tetanus (DPT) third dose coverage; (6) DPT dropout-rate; (7) care-seeking for pneumonia; and (8) oral rehydration solutions coverage. RESULTS: Overall, moderate-to-poor PHC performance was observed across the 12 countries, with substantial heterogeneity between the different subnational areas in the same country as well as within the same subnational area across both capacity and quality subdomains. The analysis of the relationship between PHC service delivery and child health outcomes revealed that recent supervision (b=0.34, p<0.01) and supervisors' feedback (b=0.28, p<0.05) were each associated with increased care-seeking for pneumonia. We also observed the associations of several measures of capacity and quality with DPT immunisation. The analysis of maternal health outcomes yielded only a few statistically significant results at p<0.05 level, however, none remained significant after adjusting for other covariates. CONCLUSION: The results of this analysis illustrate the heterogeneity in the capacity and quality of PHC service delivery within LMICs. Countries seeking to strengthen their PHC systems could improve PHC monitoring at the subnational level to better understand subnational bottlenecks in service delivery.

How can community participation strengthen a health insurance system? The case of health insurer's user associations in Colombia.

BACKGROUND: Colombia's universal health coverage programme has enrolled 98% of the population, thereby improving financial protection and health outcomes. The right to participate in the organisation of healthcare is enshrined in the 1991 Colombian Constitution. One participatory mechanism is the legal and regulatory provision that citizens can form user associations. This study examines the functionality of health insurance user associations and their influence on citizen empowerment and health insurance responsiveness. METHODS: The mixed methods study includes document review (n=72), a survey of beneficiaries (n=1311), a survey of user associations members (n=27), as well as interviews (n=19), focus group discussions (n=6) and stakeholder consultations (n=6) with user association members, government officials, and representatives from insurers, the pharmaceutical industry, and patient associations. Analysis used a content-process-context framework to understand how user associations are designed to work according to policy content, how they actually work in terms of coverage, public awareness, membership, and effectiveness, and contextual influences. FINDINGS: Colombia's user associations have a mandate to represent citizens' interests, enable participation in insurer decision-making, 'defend users' and oversee quality services. Insurers are mandated to ensure their enrollees create user associations, but are not required to provide resources to support their work. Thus, we found that user associations had been formed throughout the country, but the public was widely unaware of their existence. Many associations were weak, passive or entirely inactive. Limited market competition and toothless policies about user associations made insurers indifferent to community involvement. CONCLUSION: Currently, the initiative suffers from low awareness and low participation levels that can hardly lead to empowered enrollees and more responsive health insurance programmes. Yet, most stakeholders value the space to participate and still see potential in the initiative. This warrants a range of policy recommendations to strengthen user associations and truly enable them to effect change.

A Qualitative Assessment of the Essential Health and Nutrition Service Delivery in the Context of COVID-19 in Bangladesh: The Perspective of Divisional Directors.

Bangladesh suffered disruptions in the utilization of essential health and nutrition services (EHNS) during the COVID-19 pandemic. The magnitude of the pandemic has been documented, but little is known from the perspectives of health administrators. A rapid qualitative assessment of division-level capacity identified successes and bottlenecks in providing EHNS- and COVID-19-related services during the first months of the pandemic in Bangladesh. Semi-structured interviews were held with the Health and Family Planning Divisional Directors of the Ministry of Health and Family Welfare. The Primary Health Care System Framework guided the content analysis, focusing on (i) service delivery, (ii) communication and community outreach, and (iii) surveillance and service monitoring. Our findings identified low care seeking due to fears of getting infected and unawareness that EHNS were still available. Adaptations to telemedicine were highly heterogeneous between divisions, but collaboration with NGOs were fruitful in reinstating outreach activities. Guidelines were centered on COVID-19 information and less so on EHNS. The inflexibility of spending capacities at divisional and clinic levels hindered service provision. Misinformation and information voids were difficult to handle all around the country. Community health workers were useful for outreach communication. EHNS must be guaranteed during sanitary emergencies, and Bangladesh presented with both significant efforts and areas of opportunity for improvement.

Access to primary healthcare Services in Conflict-Affected Fragile States: a subnational descriptive analysis of educational and wealth disparities in Cameroon, Democratic Republic of Congo, Mali, and Nigeria.

BACKGROUND: Measuring and improving equitable access to care is a necessity to achieve universal health coverage. Pre-pandemic estimates showed that most conflict-affected and fragile situations were off-track to meet the Sustainable Development Goals on health and equity by 2030. Yet, there is a paucity of studies examining health inequalities in these settings. This study addresses the literature gap by applying a conflict intensity lens to the analysis of disparities in access to essential Primary Health Care (PHC) services in four conflict-affected fragile states: Cameroon, Democratic Republic of Congo, Mali and Nigeria. METHODS: For each studied country, disparities in geographic and financial access to care were compared across education and wealth strata in areas with differing levels of conflict intensity. The Demographic Health Survey (DHS) and the Uppsala Conflict Data Program were the main sources of information on access to PHC and conflict events, respectively. To define conflict intensity, household clusters were linked to conflict events within a 50-km distance. A cut-off of more than two conflict-related deaths per 100,000 population was used to differentiate medium or high intensity conflict from no or low intensity conflict. We utilized three measures to assess inequalities: an absolute difference, a concentration index, and a multivariate logistic regression coefficient. Each disparity measure was compared based on the intensity of conflict the year the DHS data was collected. RESULTS: We found that PHC access varied across subnational regions in the four countries studied; with more prevalent financial than geographic barriers to care. The magnitude of both educational and wealth disparities in access to care was higher with geographic proximity to medium or high intensity conflict. A higher magnitude of wealth rather than educational disparities was also likely to be observed in the four studied contexts. Meanwhile, only Nigeria showed statistically significant interaction between conflict intensity and educational disparities in access to care. CONCLUSION: Both educational and wealth disparities in access to PHC services can be exacerbated by geographic proximity to organized violence. This paper provides additional evidence that, despite limitations, household surveys can contribute to healthcare assessment in conflict-affected and fragile settings.

Realizing the right to health in Latin America, equitably.

This special issue "Realizing the Right to Health in Latin America and the Caribbean" provides an overview of one of the most challenging objectives of health systems: equity and the realization of the right to health. In particular, it concentrates on the issues associated with such a challenge in countries suffering of deep inequity. The experience in Latin America and the Caribbean demonstrates that the efforts of health systems to achieve Universal Health Coverage are necessary but not sufficient to achieve an equitable realization of the right to health for all. The inequitable realization of all other human rights also determines the realization of the right to health.

Health equity and COVID-19: global perspectives.

The COVID-19 is disproportionally affecting the poor, minorities and a broad range of vulnerable populations, due to its inequitable spread in areas of dense population and limited mitigation capacity due to high prevalence of chronic conditions or poor access to high quality public health and medical care. Moreover, the collateral effects of the pandemic due to the global economic downturn, and social isolation and movement restriction measures, are unequally affecting those in the lowest power strata of societies. To address the challenges to health equity and describe some of the approaches taken by governments and local organizations, we have compiled 13 country case studies from various regions around the world: China, Brazil, Thailand, Sub Saharan Africa, Nicaragua, Armenia, India, Guatemala, United States of America (USA), Israel, Australia, Colombia, and Belgium. This compilation is by no-means representative or all inclusive, and we encourage researchers to continue advancing global knowledge on COVID-19 health equity related issues, through rigorous research and generation of a strong evidence base of new empirical studies in this field.

Confidentiality agreements: a challenge in market regulation.

BACKGROUND: Sustainability and the ability to maintain the right to health, with the guarantee of access to quality medicines and health services, have been a great challenge for countries with universal health systems. The great technological advances bring with it an expressive increase in the expenditures of the health systems, especially those directed towards the acquisition of high-cost drugs, which are still under patent protection, have a high cost and, in some cases, present uncertainties about their effectiveness and safety. As a way of maintaining the proper functioning of the systems and guaranteeing access to these medicines, some countries started to negotiate discounts with manufacturing companies. Pricing agreements have been adopted by developed countries with the objective of reducing their spending on high-cost medicines and, although they represent an opportunity for better negotiation with the industries, they violate the principle of transparency that regulates the world market. However, the existence of confidentiality agreements has meant that the declared prices are not the actual prices, unfairly harming the countries that use these price lists as beacons in their systems. METHODS: Representatives of health, judicial, legislative, patient organizations and academics from eight countries in Latin America and South Korea participated in a meeting in September 2017 in Chile to discuss price confidentiality agreements and the impact on public health policies. During the meeting, participants were presented with a hypothetical case to subsidize the discussion on the topic. Divided into groups, participants should propose recommendations for the problem by pointing out the pros and cons if each proposed recommendation was adopted. The groups were then confronted by a simulated jury and finally issued a single and final recommendation for the problem. RESULTS: The topic was widely discussed and recommendations were raised by the participants. Among them, it is worth noting the elaboration of norms that regulate the negotiations of prices between the countries bringing transparency and harmony in the adopted conducts. In addition, the possible consequences and potential impacts of confidentiality on drug prices and inputs, such as information asymmetry and inequity of access between countries, were pointed out. CONCLUSION: Despite there are efforts to make price negotiations more transparent, there is still no well-established standardization that promotes a well-functioning market. Confidentiality agreements hamper the fairness of access to essential health products.

Who should pay for the continuity of post-trial health care treatments?

BACKGROUND: The bioethical debate in the world on who should pay for the continuity of post-trials treatment of patients that have medical indication remains obscure and introduces uncertainties to the patients involved in the trials. The continuity of post-trial treatment was only incorporated in the 2000s by the Helsinki Declaration. The Universal Declaration on Bioethics and Human Rights, published in 2006, points out that post-trial continuity may present a broader scope than just the availability of the investigated medicine. In the latest version of this Declaration, in 2013, it was stated that "prior to the start of the clinical trial, funders, researchers and governments of the countries participating in the research should provide post-trial access for all participants who still require an intervention that was identified as beneficial. This information should also be disclosed to participants during the informed consent process". However, a systematic review on the registration of phase III and IV clinical trials, from the clinical trials website, demonstrated that the understanding of the various guidelines and resolutions is conflicting, generating edges in the post-trial setting. For the health authorities of countries where clinical trials take place, the uncertainties about the continuity of the treatments generate gaps in care and legal proceedings against health systems, which are forced to pay for the treatments, even if they are not included in the list of medicines available to the population. METHODS: Fifty-one representatives from the health, judicial, legislative, patient and academic organizations of eight countries of Latin American and South Korea took part in a meeting in Chile, in 2017, to discuss the responsibility of the treatment continuation after clinical trials. From a hypothetical case of development of a new drug and its studies of efficacy and safety, the participants, divided in groups, proposed recommendations for the problem and pointed out the pros and cons of adopting each recommendation. The groups were, afterwards, confronted by a simulated jury and, finally, issued a final recommendation for the problem. Then, an analysis was made on the content of the recommendations and the pros and cons in adopting conservative or liberal positions, besides the possible impacts of a restrictive regulation regarding the conduction of clinical trials, pointed out by the groups, before and after the simulated jury. RESULTS: The theme was widely discussed and about 12 recommendations were proposed by the participants. The main ones took into account aspects related to patients' rights, economic factors and the development of new technologies, above the position of industry and research institutes, as well as the legislation in force in each country. CONCLUSION: The countries of Latin America and South Korea, currently, do not have laws that address patients' rights, moreover, there is no definition on who should be responsible for post-trial treatments. It is suggested that the World Health Organization issue a resolution recommending that all associated countries determine that the pharmaceutical and medical device industries, or those that sponsored it, should continue to provide treatment to all patients who participated in clinical trials and have medical indication to the continuity.

Distributional health and financial benefits of increased tobacco taxes in Colombia: results from a modelling study.

BACKGROUND: In Colombia, smoking is the second leading modifiable risk factor for premature mortality. In December 2016, Colombia passed a major tax increase on tobacco products in an effort to decrease smoking and improve population health. While tobacco taxes are known to be highly effective in reducing the prevalence of smoking, they are often criticised as being regressive in consumption. This analysis attempts to assess the distributional impact (across socioeconomic groups) of the new tax on selected health and financial outcomes. METHODS: This study builds on extended cost-effectiveness analysis methods to study the new tobacco tax in Colombia, and estimates, over a time period of 20 years and across income quintiles of the current urban population (80% of the country population), the years of life gained with smoking cessation and the increased tax revenues, all associated with a 70% relative price increase of the pack of cigarettes. Where possible, we use parameters that vary by income quintile, including price elasticity of demand for cigarettes (average of -0.44 estimated from household survey data). FINDINGS: Over 20 years, the tax increase would lead to an estimated 191 000 years of life gained among Colombia's current urban population, with the largest gains among the bottom two income quintiles. The additional annual tax revenues raised would amount to about 2%-4% of Colombia's annual government health expenditure, with the poorest quintiles bearing the smallest tax burden increase. CONCLUSIONS: The tobacco tax increase passed by Colombia has substantial implications for the country's population health and financial well-being, with large benefits likely to accrue to the two poorest quintiles of the population.

Building informed trust: developing an educational tool for injection practices and health insurance in Cambodia.

Unnecessary injections increase the risk of blood-borne infections as well as pose an avoidable financial burden on patients. Perceptions in rural Cambodia that medical drug injections provide the best quality medical care have resulted in a large proportion of the population seeking injections across medical conditions. As private providers have a higher propensity to offer injections, patients pursue more expensive care contributing to a greater financial burden. This study aimed to use an educational intervention to improve participant knowledge about injections and health insurance in order to build informed trust in safer injection practices and health insurance. Using an experimental study design, villages in rural Cambodia were randomly assigned to an intervention or control arm. Community educational workshops were implemented to improve participant knowledge about injections and health insurance. Pre-and post-intervention assessments were used to record the resulting changes in knowledge and trust in providers. Statistical analysis of survey results from the two study arms showed increases of 16.8% and 15.9% in study participant knowledge regarding injections and health insurance, respectively. Trust in health insurance increased by 12.9%. However, trust in healthcare providers proved to be resilient with small to no change. These results show that knowledge about injection safety and health insurance, as well as trust in health insurance, can be increased through information dissemination in rural Cambodia. However, health information campaigns may not easily influence people's trust in healthcare providers. Education of the general populace about safe injection practices and health insurance can contribute toward the country's efforts to reach universal health coverage.

Can task-shifting work at scale?: Comparing clinical knowledge of non-physician clinicians to physicians in Nigeria.

BACKGROUND: In contexts with severe physician shortages, the World Health Organization advocates task shifting to cadres with shorter training. To investigate the effects of task shifting at scale in primary health care, we assessed the clinical knowledge of non-physician clinicians versus physicians working in public primary care facilities in Nigeria. METHODS: We assessed 4138 health workers using clinical vignettes of hypothetical patients suffering from illnesses commonly seen in primary care. Facility-level fixed effects models were used to compare health worker knowledge of (i) consultation guidelines, (ii) diagnostic accuracy and (iii) treatment guidelines. RESULTS: Unadjusted averages of overall health worker knowledge were low across all types of worker except medical officers. After adjustment for potential confounding, the differences across all three measures between cadres became small or statistically insignificant. CONCLUSION: Non-physician clinicians can provide the same quality of primary care, for a set of common illnesses, as Medical Officers with similar personal characteristics, but clinical skills across cadres need strengthening.

Out-of-Pocket Household Expenditures on Medical Injections in Cambodia.

BACKGROUND: Cambodia has one of the highest rates of overall medical injection usage worldwide. Therapeutic injections, which are often unnecessary, contribute to the spread of blood-borne diseases. OBJECTIVE: This study describes injection practices and associated household expenditures in rural northwest Cambodia. METHODS: We assessed care-seeking patterns of surveyed adult family members who sought healthcare in the previous 30 days, including location of care, medical injection use, and out-of-pocket household expenditures for treatment. A regression model was used to explore the impact of injection use on out-of-pocket household expenditures. RESULTS: Among 480 households sampled, 298 included members who had been sick within the previous 30 days; a total of 342 episodes of care had been sought. Private providers accounted for over 66% (n = 226) of all episodes of care, with public and informal providers accounting for 20% (n = 69) and 14% (n = 47), respectively. Injections were administered in over 120 (35%) episodes of care, with 81% of injections administered by private providers. Patients who received injections incurred total out-of-pocket household expenditures that were, on average, 126,590 Cambodian Riel (KHR) (US$31.65) higher than those who did not receive injections (p < 0.01), equivalent to nearly half of the country's total annual health expenditure per capita. Receiving injections and perceived severity of illness were significantly associated with higher out-of-pocket household expenditures. CONCLUSION: This study found high levels of medical injection use, particularly among private healthcare providers, which was significantly associated with high healthcare expenditures. Reducing the number of medical injections would not only reduce disease transmission risk but also contribute to reduced healthcare costs and greater financial protection.

Night eating syndrome and its association with weight status, physical activity, eating habits, smoking status, and sleep patterns among college students.

BACKGROUND: Night eating syndrome (NES) is characterized by evening hyperphagia and/or nocturnal ingestion. OBJECTIVE: The main objective of this study was to assess the percentage of students complying with symptoms and behaviors consistent with the diagnostic criteria for NES, and explore its association with body mass index (BMI), dietary habits, physical activity, smoking status, and sleep patterns, among a sample of college students. METHODS: A cross-sectional survey was conducted among a sample of 413 undergraduate students, mean age of 20.6 ± 1.68 SD, at Central Michigan University. Students completed an online survey including demographic information and the Night Eating Diagnostic Questionnaire (NEDQ) and Pittsburgh Sleep Quality Index Questionnaire (PSQI). Participants were grouped based on self-reporting of the presence and frequency of night eating-related symptoms and behaviors related to the diagnostic criteria for NES as follows: normal, mild night eater, moderate night eater, and full-syndrome night eater. Pearson's Chi-squared, Student's t test, and Wilcoxon rank-sum test were used to test the association between students with and without any night eating behavior in relation to BMI, lifestyle variables, and sleep duration/quality. RESULTS: Results showed that the proportion of students complying with symptoms and behaviors consistent with full-syndrome of NES was 1.2%. There were no significant differences between students complying with symptoms and behaviors consistent with any level of NES and those without any night eating behavior regarding BMI, eating habits, physical activity, and smoking status. NES was significantly related to sleep duration (P = 0.023). Students complying with symptoms consistent with any level of NES reported shorter sleep time and had higher total PSQI score (6.73 ± 4.06) than students without the syndrome (5.61 ± 2.61) (P = 0.007). CONCLUSION: Although the percentage of students complying with full-syndrome NES was relatively low in our student sample, those students had shorter sleep time and poorer sleep quality than the other groups. However, it is unclear whether evening hyperphagia is a response to a lack of sleep or vice versa, and further research is needed. LEVEL OF EVIDENCE: Level III, case-control analytic study.

Looking forward to the next 15 years: innovation and new pathways for research in health equity.

Since our launch in 2002, the International Journal for Equity in Health (IJEqH) has furthered our collective understanding of equity in health and health services by providing a platform on which academics and practitioners can share their work. Today, we celebrate our fifteenth anniversary with an article collection that presents a call for new and novel research in equity in health and we invite our authors to use new approaches and methods, and to focus on emerging areas of research related to health equity in order to set the stage for the next fifteen years of health equity research.Our anniversary issue provides a platform for expanding the conceptualization, diversity of populations and study designs, and for increasing the use of novel methodologies in the field. The IJEqH has helped to support the wider group of researchers, policymakers and practitioners with a commitment to social justice and equity but there is still more to do. With the help of the highly committed editorial team and editorial board, the innovative work of researchers worldwide, and the countless of hours dedicated by hundreds of reviewers, we are confident in the IJEqH's ability to continue supporting the dissemination of health equity research for years to come.

Colombia's universal health insurance system.

By insuring more than 80 percent of its population, Colombia provides a valuable opportunity to gather evidence on a hotly debated health policy issue. Results from three studies evaluating the impact of universal health insurance in Colombia show that it has greatly increased access to and use of health services, even those that are free for all, and has reduced the incidence of catastrophic health spending. The impact has been more dramatic among those most vulnerable to health shocks: those living in rural areas, the poorest, and the self-employed.
