Background
A number of data sets show that high parity births are associated with higher child mortality than low parity births. The reasons for this relationship are not clear. In this paper we investigate whether high parity is associated with lower coverage of key health interventions that might lead to increased mortality.Methods
We used DHS data from 10 high fertility countries to examine the relationship between parity and coverage for 8 child health intervention and 9 maternal health interventions. We also used the LiST model to estimate the effect on maternal and child mortality of the lower coverage associated with high parity births.Results
Our results show a significant relationship between coverage of maternal and child health services and birth order, even when controlling for poverty. The association between coverage and parity for maternal health interventions was more consistently significant across countries all countries, while for child health interventions there were fewer overall significant relationships and more variation both between and within countries. The differences in coverage between children of parity 3 and those of parity 6 are large enough to account for a 12% difference in the under-five mortality rate and a 22% difference in maternal mortality ratio in the countries studied.Conclusions
This study shows that coverage of key health interventions is lower for high parity children and the pattern is consistent across countries. This could be a partial explanation for the higher mortality rates associated with high parity. Actions to address this gap could help reduce the higher mortality experienced by high parity birth.2.

Background
Following the adoption of the Global Action Plan for the Prevention and Control of NCDs 2013–2020, an update to the Appendix 3 of the action plan was requested by Member States in 2016, endorsed by the Seventieth World Health Assembly in May 2017 and provides a list of recommended NCD interventions. The main contribution of this paper is to present results of analyses identifying how decision makers can achieve maximum health gain using the cancer interventions listed in the Appendix 3. We also present methods used to calculate new WHO-CHOICE cost-effectiveness results for breast cancer, cervical cancer, and colorectal cancer in Southeast Asia and eastern sub-Saharan Africa.Methods
We used “Generalized Cost-Effectiveness Analysis” for our analysis which uses a hypothetical null reference case, where the impacts of all current interventions are removed, in order to identify the optimal package of interventions. All health system costs, regardless of payer, were included. Health outcomes are reported as the gain in healthy life years due to a specific intervention scenario and were estimated using a deterministic state-transition cohort simulation (Markov model).Results
Vaccination against human papillomavirus (two doses) for 9–13-year-old girls (in eastern sub-Saharan Africa) and HPV vaccination combined with prevention of cervical cancer by screening of women aged 30–49 years through visual inspection with acetic acid linked with timely treatment of pre-cancerous lesions (in Southeast Asia) were found to be the most cost effective interventions. For breast cancer, in both regions the treatment of breast cancer, stages I and II, with surgery?±?systemic therapy, at 95% coverage, was found to be the most cost-effective intervention. For colorectal cancer, treatment of colorectal cancer, stages I and II, with surgery?±?chemotherapy and radiotherapy, at 95% coverage, was found to be the most cost-effective intervention.Conclusion
The results demonstrate that cancer prevention and control interventions are cost-effective and can be implemented through a step-wise approach to achieve maximum health benefits. As the global community moves toward universal health coverage, this analysis can support decision makers in identifying a core package of cancer services, ensuring treatment and palliative care for all.3.
Background
Attempts to maintain or increase vaccination coverage almost all focus on supply side interventions: improving availability and delivery of vaccines. The effectiveness and cost-effectiveness of efforts to increase demand is uncertain.Methods
We performed a systematic review of studies that provided quantitative estimates of the impact of demand side interventions on uptake of routine childhood vaccination. We retrieved studies published up to Sept 2008.Results
The initial search retrieved 468 potentially eligible studies, including four systematic reviews and eight original studies of the impact of interventions to increase demand for vaccination. We identified only two randomised controlled trials. Interventions with an impact on vaccination uptake included knowledge translation (KT) (mass media, village resource rooms and community discussions) and non-KT initiatives (incentives, economic empowerment, household visits by extension workers). Most claimed to increase vaccine coverage by 20 to 30%. Estimates of the cost per vaccinated child varied considerably with several in the range of $10-20 per vaccinated child.Conclusion
Most studies reviewed here represented a low level of evidence. Mass media campaigns may be effective, but the impact depends on access to media and may be costly if run at a local level. The persistence of positive effects has not been investigated. The economics of demand side interventions have not been adequately assessed, but available data suggest that some may be very cost-effective.4.
Background
Malaria continues to be a public health problem despite past and on-going control efforts. For sustenance of control efforts to achieve the malaria elimination goal, it is important that the most cost-effective interventions are employed. This paper reviews studies on cost-effectiveness of malaria interventions using disability-adjusted life years.Methods
A review of literature was conducted through a literature search of international peer-reviewed journals as well as grey literature. Searches were conducted through Medline (PubMed), EMBASE and Google Scholar search engines. The searches included articles published in English for the period from 1996 to 2016. The inclusion criteria for the study were type of malaria intervention, year of publication and cost-effectiveness ratio in terms of cost per DALY averted. We included 40 studies which specifically used the DALY metric in cost-effectiveness analysis (CEA) of malaria interventions.Results
The majority of the reviewed studies (75%) were done using data from African settings with the majority of the interventions (60.0%) targeting all age categories. Interventions included case treatment, prophylaxis, vector control, insecticide treated nets, early detection, environmental management, diagnosis and educational programmes. Sulfadoxine–pyrimethamine was the most common drug of choice in malaria prophylaxis, while artemisinin-based combination therapies were the most common drugs for case treatment. Based on guidelines for CEA, most interventions proved cost-effective in terms of cost per DALYs averted for each intervention.Conclusion
The DALY metric is a useful tool for determining the cost-effectiveness of malaria interventions. This paper demonstrates the importance of CEA in informing decisions made by policy makers.5.

Background
Policymakers need to know the cost-effectiveness of interventions to prevent type 2 diabetes (T2D). The objective of this study was to estimate the cost-effectiveness of a T2D prevention initiative targeting weight reduction, increased physical activity and healthier diet in persons in pre-diabetic states by comparing a hypothetical intervention versus no intervention in a Swedish setting.Methods
A Markov model was used to study the cost-effectiveness of a T2D prevention program based on lifestyle change versus a control group where no prevention was applied. Analyses were done deterministically and probabilistically based on Monte Carlo simulation for six different scenarios defined by sex and age groups (30, 50, 70 years). Cost and quality adjusted life year (QALY) differences between no intervention and intervention and incremental cost-effectiveness ratios (ICERs) were estimated and visualized in cost-effectiveness planes (CE planes) and cost-effectiveness acceptability curves (CEA curves).Results
All ICERs were cost-effective and ranged from 3833 €/QALY gained (women, 30 years) to 9215 €/QALY gained (men, 70 years). The CEA curves showed that the probability of the intervention being cost-effective at the threshold value of 50,000 € per QALY gained was very high for all scenarios ranging from 85.0 to 91.1%.Discussion/conclusion
The prevention or the delay of the onset of T2D is feasible and cost-effective. A small investment in healthy lifestyle with change in physical activity and diet together with weight loss are very likely to be cost-effective.6.

Background
Inequality in healthcare across population groups in low-income countries is a growing topic of interest in global health. The Lives Saved Tool (LiST), which uses health intervention coverage to model maternal, neonatal, and child health outcomes such as mortality rates, can be used to analyze the impact of within-country inequality.Methods
Data from nationally representative household surveys (98 surveys conducted between 1998 and 2014), disaggregated by wealth quintile, were used to create a LiST analysis that models the impact of scaling up health intervention coverage for the entire country from the national average to the rate of the top wealth quintile (richest 20% of the population). Interventions for which household survey data are available were used as proxies for other interventions that are not measured in surveys, based on co-delivery of intervention packages.Results
For the 98 countries included in the analysis, 24–32% of child deaths (including 34–47% of neonatal deaths and 16–19% of post-neonatal deaths) could be prevented by scaling up national coverage of key health interventions to the level of the top wealth quintile. On average, the interventions with most unequal coverage rates across wealth quintiles were those related to childbirth in health facilities and to water and sanitation infrastructure; the most equally distributed were those delivered through community-based mass campaigns, such as vaccines, vitamin A supplementation, and bednet distribution.Conclusions
LiST is a powerful tool for exploring the policy and programmatic implications of within-country inequality in low-income, high-mortality-burden countries. An “Equity Tool” app has been developed within the software to make this type of analysis easily accessible to users.7.

Background
Nearly every second person suffers from mental illness at some point in their life. In this regard, stress-induced illnesses play a central role. Stress cannot be avoided; thus, interventions that promote resilience in the face of stress are particularly significant.Objective
The paper gives a short overview of the current status quo in the development of evidence-based resilience interventions.Materials and methods
The chosen method is a narrative review that takes into account papers with relational resilience constructs such as concept analysis, systematic reviews, and empirical studies of international resilience research.Results
Currently, the main challenge for program developers is to identify valid protective factors within resilience research which match the target and target group of a special intervention.Conclusion
There is a need for systematic reviews to systematize heterogeneous resilience studies. Based on such reviews, the selection of protective factors that should be promoted in an intervention can be justified.9.

Background
The coverage of prevention and treatment strategies for ischemic heart disease and stroke is very low in Ethiopia. In view of Ethiopia’s meager healthcare budget, it is important to identify the most cost-effective interventions for further scale-up. This paper’s objective is to assess cost-effectiveness of prevention and treatment of ischemic heart disease (IHD) and stroke in an Ethiopian setting.Methods
Fifteen single interventions and sixteen intervention packages were assessed from a healthcare provider perspective. The World Health Organization’s Choosing Interventions that are Cost-Effective model for cardiovascular disease was updated with available country-specific inputs, including demography, mortality and price of traded and non-traded goods. Costs and health benefits were discounted at 3 % per year. Incremental cost-effectiveness ratios are reported in US$ per disability adjusted life year (DALY) averted. Sensitivity analysis was undertaken to assess robustness of our results.Results
Combination drug treatment for individuals having >35 % absolute risk of a CVD event in the next 10 years is the most cost-effective intervention. This intervention costs US$67 per DALY averted and about US$7 million annually. Treatment of acute myocardial infarction (AMI) (costing US$1000–US$7530 per DALY averted) and secondary prevention of IHD and stroke (costing US$1060–US$10,340 per DALY averted) become more efficient when delivered in integrated packages. At an annual willingness-to-pay (WTP) level of about US$3 million, a package consisting of aspirin, streptokinase, ACE-inhibitor and beta-blocker for AMI has the highest probability of being most cost-effective, whereas as WTP increases to > US$7 million, combination drug treatment to individuals having >35 % absolute risk stands out as the most cost-effective strategy. Cost-effectiveness ratios were relatively more sensitive to halving the effectiveness estimates as compared with doubling the price of drugs and laboratory tests.Conclusions
In Ethiopia, the escalating burden of CVD and its risk factors warrants timely action. We have demonstrated that selected CVD intervention packages could be scaled up at a modest budget increase. The level of willingness-to-pay has important implications for interventions’ probability of being cost-effective. The study provides valuable evidence for setting priorities in an essential healthcare package for CVD in Ethiopia.10.

Background
This study evaluates the cost-effectiveness of the DAZT program for scaling up treatment of acute child diarrhea in Gujarat India using a net-benefit regression framework.Methods
Costs were calculated from societal and caregivers’ perspectives and effectiveness was assessed in terms of coverage of zinc and both zinc and Oral Rehydration Salt. Regression models were tested in simple linear regression, with a specified set of covariates, and with a specified set of covariates and interaction terms using linear regression with endogenous treatment effects was used as the reference case.Results
The DAZT program was cost-effective with over 95% certainty above $5.50 and $7.50 per appropriately treated child in the unadjusted and adjusted models respectively, with specifications including interaction terms being cost-effective with 85–97% certainty.Discussion
Findings from this study should be combined with other evidence when considering decisions to scale up programs such as the DAZT program to promote the use of ORS and zinc to treat child diarrhea.11.
Background
Calls have been made for improved measurement of coverage for maternal, newborn and child health interventions. Recently, methods linking household and health facility surveys have been used to improve estimation of intervention coverage. However, linking methods rely the availability of household and health facility surveys which are temporally matched. Because nationally representative health facility assessments are not yet routinely conducted in many low and middle income countries, estimates of intervention coverage based on linking methods can be produced for only a subset of countries. Estimates of intervention coverage are a critical input for modelling the health impact of intervention scale-up in the Lives Saved Tool (LiST). The purpose of this study was to develop a data-driven approach to estimate coverage for a subset of antenatal care interventions modeled in LiST.Methods
Using a five-step process, estimates of population level coverage for syphilis detection and treatment, case management of diabetes, malaria infection, hypertensive disorders, and pre-eclampsia, were computed by linking household and health facility surveys. Based on data characterizing antenatal care and estimates of coverage derived from the linking approach, predictive models for intervention coverage were developed. Updated estimates of coverage based on the predictive models were compared, first with current default proxies, then with estimates based on the linking approach. Model fit and accuracy were assessed using three measures: the coefficient of determination, Pearson’s correlation coefficient, and the root mean square error (RMSE).Results
The ability to predict intervention coverage was fairly accurate across all interventions considered. Predictive models accounted for 20–63% of the variance in intervention coverages, and correlation coefficients ranged from 0.5 to 0.83. The predictive model used to estimate coverage of management of pre-eclampsia performed relatively better (RMSE = 0.11) than the model estimating coverage of diabetes case management (RMSE = 0.19).Conclusions
The new approach to estimate coverage represents an improvement over current default proxies in LiST. As the availability of reliable coverage data improves, impact estimates generated by LiST will improve. This study underscores the need for continued efforts to improve coverage measurement, while bringing to the fore the importance of health facility assessments as complementary data sources.12.

Background
Routine childhood immunization remains an important strategy for achieving polio eradication and maintaining a polio-free world. To address gaps in reported administrative coverage data, community surveys were conducted to verify coverage, and guide strategic interventions for improved coverage.Methods
We reviewed the conduct of community surveys by World Health Organization (WHO) field volunteers deployed as part of the surge capacity to Kaduna state and the use of survey results between July 2015 and June 2016. Monthly and quarterly collation and use of these data to guide the deployment of various interventions aimed at strengthening routine immunization in the state.Results
Over 97,000 children aged 0–11?months were surveyed by 138 field volunteers across 237 of the 255 wards in Kaduna state. Fully or appropriately immunized children increased from 67% in the fourth quarter of 2015 to 76% by the end of the second quarter of 2016. Within the period reviewed, the number of local government areas with <?80% coverage reduced from eight to zero.Conclusions
The routine conduct of community surveys by volunteers to inform interventions has shown an improvement in the vaccination status of children 0–11?months in Kaduna state and remains a useful tool in addressing administrative data quality issues.14.
Background
The Missed Opportunity tool was developed as an application in the Lives Saved Tool (LiST) to allow users to quickly compare the relative impact of interventions. Global Financing Facility (GFF) investment cases have been identified as a potential application of the Missed Opportunity analyses in Democratic Republic of the Congo (DRC), Ethiopia, Kenya, and Tanzania, to use ‘lives saved’ as a normative factor to set priorities.Methods
The Missed Opportunity analysis draws on data and methods in LiST to project maternal, stillbirth, and child deaths averted based on changes in interventions’ coverage. Coverage of each individual intervention in LiST was automated to be scaled up from current coverage to 90% in the next year, to simulate a scenario where almost every mother and child receive proven interventions that they need. The main outcome of the Missed Opportunity analysis is deaths averted due to each intervention.Results
When reducing unmet need for contraception is included in the analysis, it ranks as the top missed opportunity across the four countries. When it is not included in the analysis, top interventions with the most total deaths averted are hospital-based interventions such as labor and delivery management in the CEmOC and BEmOC level, and full treatment and supportive care for premature babies, and for sepsis/pneumonia.Conclusions
The Missed Opportunity tool can be used to provide a quick, first look at missed opportunities in a country or geographic region, and help identify interventions for prioritization. While it is a useful advocate for evidence-based priority setting, decision makers need to consider other factors that influence decision making, and also discuss how to implement, deliver, and sustain programs to achieve high coverage.15.

Background
Hepatitis C virus (HCV) is a major health issue worldwide. New generation of direct-active antiviral medications is an epoch-making turning point in the management of HCV infections.Objective
Conducing a cost-effectiveness analysis comparing the combination of elbasvir/grazoprevir and sofosbuvir?+?pegylated interferon/ribavirin for the management of all HCV patients (even those in the initial stages of fibrosis).Methods
A Markov model was built on the natural history of the disease to assess the efficacy of the alternatives. The outcomes are expressed in terms of quality adjusted life-years (QALYs) and result in terms of incremental cost-effectiveness ratio).Results
Elbasvir/grazoprevir implies an expenditure of €21,104,253.74 with a gain of 19,287.90 QALYs and sofosbuvir?+?pegylated interferon/ribavirin implies an expenditure of €31,904,410.11 with a gain of 18,855.96 QALYs. Elbasvir/grazoprevir is thus a dominant strategy.Conclusion
Consideration should be given to the opportunity cost of not treating patients with a lower degree of fibrosis (F0–F2).16.

Objective
Evaluate the effectiveness of a continuing educational intervention on primary health care professionals’ familiarity with information important to nutritional care in a palliative phase, their collaboration with other caregivers, and their level of knowledge about important aspects of nutritional care.Design
Observational cohort study.Setting
10 primary health care centers in Stockholm County, Sweden.Participants
140 district nurses/registered nurses and general practitioners/physicians working with home care.Intervention
87 professionals participated in the intervention group (IG) and 53 in the control group (CG). The intervention consisted of a web-based program offering factual knowledge; a practical exercise linking existing and new knowledge, abilities, and skills; and a case seminar facilitating reflection.Measurements
The intervention’s effects were measured by a computer-based study-specific questionnaire before and after the intervention, which took approximately 1 month. The CG completed the questionnaire twice (1 month between response occasions). The intervention effects, odds ratios, were estimated by an ordinal logistic regression.Results
In the intra-group analyses, statistically significant changes occurred in the IG’s responses to 28 of 32 items and the CG’s responses to 4 of 32 items. In the inter-group analyses, statistically significant effects occurred in 20 of 32 statements: all 14 statements that assessed familiarity with important concepts and all 4 statements about collaboration with other caregivers but only 2 of the 14 statements concerning level of knowledge. The intervention effect varied between 2.5 and 12.0.Conclusion
The intervention was effective in increasing familiarity with information important to nutritional care in a palliative phase and collaboration with other caregivers, both of which may create prerequisites for better nutritional care. However, the intervention needs to be revised to better increase the professionals’ level of knowledge about important aspects of nutritional care.17.
Background
Many young children experience the death of a family member and they may be at risk for developing psychological and behavioral problems, but not much is known about how to help young children cope with such a stressful and painful experience.Objective
The purposes of this study are to identify the interventions for bereaved young children and examine the effectiveness of the interventions.Methods
A systematic review of the literature was performed to investigate the effects of interventions for preschool-age children (3–5 years) who experience the death of a family member.Results
Seventeen studies that met the inclusion criteria for the purpose of this review were identified. All of the studies involved a small sample, and majority of the studies mixed preschool children with other older children in the sample. Play-based therapies were the most common interventions for grieving young children. Involving parents in the interventions, regardless of their therapeutic orientation, was a critical ingredient.Conclusions
Limited empirical evidence of positive intervention outcomes for preschool-age bereaved children was available. Surviving parents were seen as an important agent to help young children grieve and cope with the experience of loss. Implications for school mental health practice and research are provided.18.

Background
The nature of amyotrophic lateral sclerosis (ALS) is progressive and degenerative, thus influencing individuals physically, emotionally, and socially. A broad review of qualitative studies that describe the personal experiences of people with ALS with physiotherapy, occupational therapy and speech and language pathology interventions, and how those affect QoL is warranted.Purpose
This study synthesizes qualitative research regarding the potential that rehabilitation interventions have to maintain and/or improve QoL from the perspective of people with ALS.Methods
The SPIDER search strategy was applied and five articles met inclusion criteria addressing the perceived impact of rehabilitation on QoL for individuals with ALS.Results
Four themes emerged: the concept of control; adapting interventions to disease stage; struggles with interventions; and barriers between healthcare providers and patients.Conclusions
Rehabilitation interventions were perceived to have potential to support QoL by people with ALS. Advantages and limitations of rehabilitation services within this population were identified.19.

Objectives
Preventing or delaying frailty has important benefits in the elderly, and in health and social services. Studies have demonstrated the effectiveness of multifactorial interventions in the frail elderly, but there are fewer studies on community-dwelling pre-frail individuals. Identifying pre-frail individuals susceptible to intervention could prevent or delay frailty and its consequences and associated disability and might reverse the state from pre-frail to robust. To evaluate a multifactorial, interdisciplinary primary care intervention in community-dwelling pre-frail elderly patients aged ≥ 80 years.Design
Randomized clinical trial in a Barcelona primary healthcare centre.Setting
We included 200 community-dwelling subjects aged ≥ 80 years meeting the Fried pre-frailty criteria. Participants were randomized to intervention and control groups.Intervention
The intervention group received a 6-month interdisciplinary intervention based on physical exercise, Mediterranean diet advice, assessment of inadequate prescribing in polypharmacy patients and social assessment, while the control group received standard primary healthcare treatment.Results
173 pre-frail participants (86.5%) completed the study; mean age 84.5 years, 64.5% female. At twelve months, frailty was lower in the intervention group (RR 2.90; 95%CI 1.45 to 8.69). Reversion to robustness was greater in the intervention group (14.1% vs.1.1%, p <0.001). Functional and nutritional status, adherence to Mediterranean diet, quality of life, and functional mobility were improved in the intervention group (p ≤0.001).Conclusion
A multifactorial, interdisciplinary primary healthcare intervention focused on physical exercise, nutrition, review of polypharmacy and social assessment prevented frailty in pre-frail elderly patients, and improved functional capacity, quality of life and adherence to the Mediterranean diet.20.
