Understanding global health governance as a complex adaptive system.

The transition from international to global health reflects the rapid growth in the numbers and nature of stakeholders in health, as well as the constant change embodied in the process of globalisation itself. This paper argues that global health governance shares the characteristics of complex adaptive systems, with its multiple and diverse players, and their polyvalent and constantly evolving relationships, and rich and dynamic interactions. The sheer quantum of initiatives, the multiple networks through which stakeholders (re)configure their influence, the range of contexts in which development for health is played out – all compound the complexity of this system. This paper maps out the characteristics of complex adaptive systems as they apply to global health governance, linking them to developments in the past two decades, and the multiple responses to these changes. Examining global health governance through the frame of complexity theory offers insight into the current dynamics of governance, and while providing a framework for making meaning of the whole, opens up ways of accessing this complexity through local points of engagement.

Health systems frameworks in their political context: framing divergent agendas

BackgroundDespite the mounting attention for health systems and health systems theories, there is a persisting lack of consensus on their conceptualisation and strengthening. This paper contributes to structuring the debate, presenting landmarks in the development of health systems thinking against the backdrop of the policy context and its dominant actors. We argue that frameworks on health systems are products of their time, emerging from specific discourses. They are purposive, not neutrally descriptive, and are shaped by the agendas of their authors.DiscussionThe evolution of thinking over time does not reflect a progressive accumulation of insights. Instead, theories and frameworks seem to develop in reaction to one another, partly in line with prevailing paradigms and partly as a response to the very different needs of their developers. The reform perspective considering health systems as projects to be engineered is fundamentally different from the organic view that considers a health system as a mirror of society. The co-existence of health systems and disease-focused approaches indicates that different frameworks are complementary but not synthetic.The contestation of theories and methods for health systems relates almost exclusively to low income countries. At the global level, health system strengthening is largely narrowed down to its instrumental dimension, whereby well-targeted and specific interventions are supposed to strengthen health services and systems or, more selectively, specific core functions essential to programmes. This is in contrast to a broader conceptualization of health systems as social institutions.SummaryHealth systems theories and frameworks frame health, health systems and policies in particular political and public health paradigms. While there is a clear trend to try to understand the complexity of and dynamic relationships between elements of health systems, there is also a demand to provide frameworks that distinguish between health system interventions, and that allow mapping with a view of analysing their returns. The choice for a particular health system model to guide discussions and work should fit the purpose. The understanding of the underlying rationale of a chosen model facilitates an open dialogue about purpose and strategy.

The rhetoric of sector-wide approaches for health development

The past decade has witnessed an increasing concerns over the effectiveness of project-based development assistance and the promotion of sector-wide approaches (SWAps) to health as a means to increase donor collaboration, consolidate local management of resources and undertake the policy and systems reform necessary to achieve a greater impact on health issues. The concept has gained the support of both the World Bank and the World Health Organisation. as well as key bilateral donors, and dominates current initiatives in development assistance for health. This paper examines the proposal of SWAps as rhetoric, and seeks to understand how that rhetoric functions, despite the variable application of its constituent elements and the range of contexts in which it operates.

Behavioral sleep interventions in the first six months of life do not improve outcomes for mothers or infants: a systematic review.

Objective: The United Kingdoms National Institute for Health Research has recently invited proposals for the design of a multicomponent primary care package of behavioral interventions to reduce parental distress caused by excessive infant crying in the first 6 months of life. A systematic review was performed to determine whether behavioral interventions for sleep, when applied by parents to infants younger than 6 months, improve maternal and infant outcomes. Methods: Searches of PubMed, CINAHL, and Cochrane Database of Systematic Reviews were conducted to identify systematic reviews, meta-analyses, clinical trials, and cohort studies investigating the effects of behavioral sleep interventions in infants younger than 6 months (January 1993–August 2013). The evidence is critically analyzed, according to PRISMA guidelines. Results: Cry-fuss, feeding, and sleep problems emerge out of multiple dynamically interacting and co-evolving variables in early life and are for this reason generically referred to as regulatory problems. Studies that link behavioral interventions for sleep in the first 6 months with positive effects on maternal and infant health demonstrate 3 methodological constraints. They fail to identify and control for feeding difficulties, fail to distinguish between the neurodevelopmentally different first and second halves of the first year of life, and apply reductive analyses to evaluations of complex interventions. Despite substantial investment in recent years in implementation and evaluation of behavioral interventions for infant sleep in the first 6 months, these strategies have not been shown to decrease infant crying, prevent sleep and behavioral problems in later childhood, or protect against postnatal depression. In addition, behavioral interventions for infant sleep, applied as a population strategy of prevention from the first weeks and months, risk unintended outcomes, including increased amounts of problem crying, premature cessation of breastfeeding, worsened maternal anxiety, and, if the infant is required to sleep either day or night in a room separate from the caregiver, an increased risk of Sudden Infant Death Syndrome. Conclusion: The belief that behavioral intervention for sleep in the first 6 months of life improves outcomes for mothers and babies is historically constructed, overlooks feeding problems, and biases interpretation of data.

Managing infants who cry excessively in the first few months of life

#### Summary points Community cohort studies report that a fifth of parents say that their otherwise healthy baby has cry-fuss problems at two months of age.1 2 Excessive crying is usually a transient neurodevelopmental phenomenon, although it may herald problems that are more long term and serious. Various studies have found that it is often difficult for parents to access the help they need when they experience problem crying; that they resort to use of multiple health services, including of emergency departments; and that they receive conflicting advice.3 w1 We review evidence from heterogeneous studies across multiple health disciplines to provide a practical guide to the management of term infants who cry excessively in the first few months of life. Our review is aimed at paediatricians, general practitioners, community child health nurses, and midwives. Although definitions of infant crying vary considerably, for practical purposes we use the terms cry-fuss behaviour, excessive crying, colic, and unsettled infant behaviour interchangeably to refer to any crying behaviour that parents report …

Compiling mortality statistics from civil registration systems in Viet Nam: the long road ahead

Accurate mortality statistics, needed for population health assessment, health policy and research, are best derived from data in vital registration systems. However, mortality statistics from vital registration systems are not available for several countries including Viet Nam. We used a mixed methods case study approach to assess vital registration operations in 2006 in three provinces in Viet Nam (Hòa Bình, Thùa Thiên-Hué and Bình Duong), and provide recommendations to strengthen vital registration systems in the country. For each province we developed life tables from population and mortality data compiled by sex and age group. Demographic methods were used to estimate completeness of death registration as an indicator of vital registration performance. Qualitative methods (document review, key informant interviews and focus group discussions) were used to assess administrative, technical and societal aspects of vital registration systems. Completeness of death registration was low in all three provinces. Problems were identified with the legal framework for registration of early neonatal deaths and deaths of temporary residents or migrants. The system does not conform to international standards for reporting cause of death or for recording detailed statistics by age, sex and cause of death. Capacity-building along with an intersectoral coordination committee involving the Ministries of Justice and Health and the General Statistics Office would improve the vital registration system, especially with regard to procedures for death registration. There appears to be strong political support for sentinel surveillance systems to generate reliable mortality statistics in Viet Nam.

Sustainability and cost of a community-based strategy against Aedes aegypti in northern and central Vietnam.

We previously reported a new community-based mosquito control that resulted in the elimination of Aedes aegypti in 40 of 46 communes in northern and central Vietnam. During 2007 and 2008, we revisited Nam Dinh and Khanh Hoa provinces in northern and central Vietnam, respectively, to evaluate whether or not these programs were still being maintained 7 years and 4.5 years after formal project activities had ceased, respectively. Using a previously published sustainability framework, we compared 13 criteria from Tho Nghiep commune in Nam Dinh where the local community had adopted our community-based project model using Mesocyclops from 2001. These data were compared against a formal project commune, Xuan Phong, where our successful intervention activities had ceased in 2000 and four communes operating under the National Dengue Control Program with data available. In Khanh Hoa province, we compared 2008 data at Ninh Xuan commune with data at project completion in 2003 and benchmarked these, where possible, against an untreated control commune, Ninh Binh, where few control activities had been undertaken. The three communes where the above community-based strategy had been adopted were rated as well-sustained with annual recurrent total costs (direct and indirect) of

Road traffic related mortality in Vietnam: Evidence for policy from a national sample mortality surveillance system

An outbreak of 12 cases of meningitis, 11 caused by Neisseria meningitidis serogroup C, occurred at Doomadgee from September, 1990, to April, 1991. The incidence of meningitis was 17.55/10(3) person-years. Only children aged 1-10 years were affected. In October, 1990, or shortly thereafter, 473/509 children aged between 1 and 15 years inclusive had one dose of Mencevax AC. From the time of vaccination until April, 1991, a further eight cases occurred, six in vaccinated children. Vaccine efficacy in 1-15 year olds was calculated as 77%. Despite this, in April, 1991, the prevalence of antibody to group C polysaccharide in vaccinated children (78%) was not significantly different from that in unvaccinated children and adults. 46 nonresponders were revaccinated, and, in February, 1992, 78% had antibodies to group C polysaccharide. In April, 1991, an estimated 3.0% of the population had group C organisms, carriage being directly related to household crowding. In June, 1991, 2 months after mass prophylaxis with rifampicin, none of these individuals were carriers. In October, 1991, the carriage rate of group C organisms was 0.64%. There have been no further cases caused by the epidemic strain. Although uncrowded housing is a basic need, mass chemoprophylaxis and two doses of vaccine for children should be used in similar outbreaks.
