[Early effect of vaccination on the positivity rate of salivary tests performed on nursing home staff in the Walloon Region]

In Belgium, nursing homes (NH) were disproportionately affected by the SARS-CoV-2 pandemic. The objective of this study was to compare the risk of SARS-CoV-2 infection in vaccinated and unvaccinated staff members.

METHODS

This was a prospective cohort study conducted between February 1 and April 02, 2021, in 99 nursing homes (NHs) in the Walloon Region, a few weeks after the start of the vaccination campaign. A mixed-effects logistic regression analysis was performed to assess the relationship between COVID results of molecular tests on saliva samples of the NHs' staff and their vaccination status.

RESULTS

Only 32 (0,1 %) of 39 267 saliva tests were positive. Logistic analysis showed that unvaccinated nursing home staff were 4 times more likely to develop COVID-19 than vaccinated staff during the study period.

CONCLUSION

This study demonstrated an early decreased risk of infection in vaccinated NHs staff. Saliva tests were designed to be convenient, less expensive and non-invasive, and could be considered as an alternative to nasopharyngeal tests.

COVID-19 cases, hospitalizations and deaths in Belgian nursing homes: results of a surveillance conducted between April and December 2020

BACKGROUND

In Belgium, the first COVID-19 death was reported on 10 March 2020. Nursing home (NH) residents are particularly vulnerable for COVID-19, making it essential to follow-up the spread of COVID-19 in this setting. This manuscript describes the methodology of surveillance and epidemiology of COVID-19 cases, hospitalizations and deaths in Belgian NHs.

METHODS

A COVID-19 surveillance in all Belgian NHs (n = 1542) was set up by the regional health authorities and Sciensano. Aggregated data on possible/confirmed COVID-19 cases and hospitalizations and case-based data on deaths were reported by NHs at least once a week. The study period covered April-December 2020. Weekly incidence/prevalence data were calculated per 1000 residents or staff members.

RESULTS

This surveillance has been launched within 14 days after the first COVID-19 death in Belgium. Automatic data cleaning was installed using different validation rules. More than 99% of NHs participated at least once, with a median weekly participation rate of 95%. The cumulative incidence of possible/confirmed COVID-19 cases among residents was 206/1000 in the first wave and 367/1000 in the second wave. Most NHs (82%) reported cases in both waves and 74% registered ≥10 possible/confirmed cases among residents at one point in time. In 51% of NHs, at least 10% of staff was absent due to COVID-19 at one point. Between 11 March 2020 and 3 January 2021, 11,329 COVID-19 deaths among NH residents were reported, comprising 57% of all COVID-19 deaths in Belgium in that period.

CONCLUSIONS

This surveillance was crucial in mapping COVID-19 in this vulnerable setting and guiding public health interventions, despite limitations of aggregated data and necessary changes in protocol over time. Belgian NHs were severely hit by COVID-19 with many fatal cases. The measure of not allowing visitors, implemented in the beginning of the pandemic, could not avoid the spread of SARS-CoV-2 in the NHs during the first wave. The virus was probably often introduced by staff. Once the virus was introduced, it was difficult to prevent healthcare-associated outbreaks. Although, in contrast to the first wave, personal protective equipment was available in the second wave, again a high number of cases were reported.

Establishing an ad hoc COVID-19 mortality surveillance during the first epidemic wave in Belgium, 1 March to 21 June 2020

BackgroundCOVID-19-related mortality in Belgium has drawn attention for two reasons: its high level, and a good completeness in reporting of deaths. An ad hoc surveillance was established to register COVID-19 death numbers in hospitals, long-term care facilities (LTCF) and the community. Belgium adopted broad inclusion criteria for the COVID-19 death notifications, also including possible cases, resulting in a robust correlation between COVID-19 and all-cause mortality.AimTo document and assess the COVID-19 mortality surveillance in Belgium.MethodsWe described the content and data flows of the registration and we assessed the situation as of 21 June 2020, 103 days after the first death attributable to COVID-19 in Belgium. We calculated the participation rate, the notification delay, the percentage of error detected, and the results of additional investigations.ResultsThe participation rate was 100% for hospitals and 83% for nursing homes. Of all deaths, 85% were recorded within 2 calendar days: 11% within the same day, 41% after 1 day and 33% after 2 days, with a quicker notification in hospitals than in LTCF. Corrections of detected errors reduced the death toll by 5%.ConclusionBelgium implemented a rather complete surveillance of COVID-19 mortality, on account of a rapid investment of the hospitals and LTCF. LTCF could build on past experience of previous surveys and surveillance activities. The adoption of an extended definition of 'COVID-19-related deaths' in a context of limited testing capacity has provided timely information about the severity of the epidemic.

Using geographically weighted Poisson regression to examine the association between socioeconomic factors and hysterectomy incidence in Wallonia, Belgium

BACKGROUND

Various studies have investigated geographical variations in the incidence of hysterectomy in Western countries and analyzed socioeconomic factors to explain those variations. However, few studies have used spatial analysis to characterize them. Geographically weighted Poisson regression (GWPR) explores the spatially varying impacts of covariates across a study area and focuses attention on local variations. Given the potential of GWPR to guide decision-making, this study aimed to describe the geographical distribution of hysterectomy incidence for benign indications in women older than 15 years old (15+) at the municipal level in Wallonia (southern region of Belgium) and to analyze potential associations with socioeconomic factors ('Education/training', 'Income and purchasing power' and 'Health and care') influencing the use of this surgery.

METHODS

We carried out an ecological study on data for women aged 15+ living in one of the 262 Walloon municipalities who underwent hysterectomies for benign indications between 2012 and 2014. We linked standardized hysterectomy rates to three municipal-level socioeconomic factors ('Education/training', 'Income and purchasing power' and 'Health and care'). Then, a Poisson regression model and a GWPR were applied to study the relationships between hysterectomy incidence and socioeconomic covariates in Wallonia.

RESULTS

The hysterectomy rate varied across the region. The Poisson regression revealed a positive and significant association between the hysterectomy rate and 'Income and purchasing power', and a negative and significant association between hysterectomies and 'Health and care'. The same associations were seen in the GWPR model. The latter demonstrated that the association between hysterectomies and 'Education and training' ranged from negative to positive over the study area.

CONCLUSIONS

Hysterectomy incidence was shown to have nonstationary relationships with socioeconomic factors. These results support the development of targeted interventions for a more appropriate use of this surgery.

[Analysis of comorbidities in hospitalized patients for ischemic stroke and their effects on lethality]

OBJECTIVES

The aim of the study consists of analyzing the comorbidities of acute ischemic stroke and those influencing its hospital lethality.

METHODS

We considered patients from Wallonia aged 25 years or more and admitted to a Belgian hospital for an acute ischemic stroke in 2013 and 2014. The analyzed medico-administrative data are taken from the Minimum Hospital Summary. A factorial correspondence analysis (FCA) was used to demonstrate the comorbidities profiles. A logistic regression was used to analyse the comorbidities influencing hospital lethality by ischemic stroke.

RESULTS

The stroke risk factors vary according to the age. Cardiac problems are more common in older people aged 85 years or more. High blood pressure, hypercholesterolemia and diabetes are more present between 65- and 84-year-olds. Overweight is more present between 55 and 74-year-olds. People who are addicted to alcohol or tobacco are often 65 years or younger. The logistic regression showed that age and heart problems are the risk factors that increase lethality. However there is a lethality diminution in the presence of high blood pressure, hypercholesterolemia, overweight and addiction to alcohol or tobacco.

CONCLUSION

This study demonstrates that medico-administrative databases and factorial statistical methods are perfectly adapted to confirm the ischemic stroke risk factors. This type of study will allow to target with more precision the secondary and tertiary prevention actions of stroke.

Data on short-term effect of nitrogen dioxide on cardiovascular health in Wallonia, Belgium

Data presented in this article are related to the research paper entitled “Short-term effects of nitrogen dioxide on hospital admissions for cardiovascular disease in Wallonia, Belgium.” (Collart et al., in press) [1].

Nitrogen dioxide concentrations showed a strong seasonal pattern with higher levels in the cold period than in the warm period. A minimum of 13.1 µg/m³ in July and a maximum of 26.9 µg/m³ in January were observed. The coldest months are December, January and February and the hottest months are June, July and August. Temperature and nitrogen dioxide were negatively correlated in the cold period and positively correlated in the warm period.

For the period 2008–2011 there were 113 147 hospital admissions for cardiovascular disease. Forty-five percent of patients were women and 66.5% were 65 and older. Heart rhythm disorders account for the majority of hospital admissions for cardiovascular disease. Our data confirms the existence of an association between NO₂ and cardiovascular disease. Apart from haemorrhagic stroke, the strongest association between NO₂ concentrations and number of hospital admissions is observed at lag 0. For haemorrhagic stroke, the association is strongest with a delay of 2 days. All associations calculated without stratification are statistically significant and range from an excess relative risk of 2.8% for myocardial infarction to 4.9% for haemorrhagic strokes.

Short-term effects of nitrogen dioxide on hospital admissions for cardiovascular disease in Wallonia, Belgium

Many studies have shown a short-term association between NO₂ and cardiovascular disease. However, few data are available on the delay between exposure and a health-related event. The aim of the present study is to determine the strength of association between NO₂ and cardiovascular health in Wallonia for the period 2008-2011. This study also seeks to evaluate the effects of age, gender, season and temperature on this association. The effect of the delay between exposure and health-related event was also investigated. The daily numbers of hospital admissions for arrhythmia, acute myocardial infarction, ischemic and haemorrhagic stroke were taken from a register kept by Belgian hospitals. Analyses were performed using the quasi-Poisson regression model adjusted for seasonality, long-term trend, day of the week, and temperature. Our study confirms the existence of an association between NO₂ and cardiovascular disease. Apart from haemorrhagic stroke, the strongest association between NO₂ concentrations and number of hospital admissions is observed at lag 0. For haemorrhagic stroke, the association is strongest with a delay of 2days. All associations calculated without stratification are statistically significant and range from an excess relative risk of 2.8% for myocardial infarction to 4.9% for haemorrhagic strokes. The results of this study reinforce the evidence of the short-term effects of NO₂ on hospital admissions for cardiovascular disease. The different delay between exposure and health-related event for haemorrhagic stroke compared to ischemic stroke suggests different mechanisms of action.

A comparison of hierarchical cluster analysis and league table rankings as methods for analysis and presentation of district health system performance data in Uganda

In 2003, the Uganda Ministry of Health introduced the district league table for district health system performance assessment. The league table presents district performance against a number of input, process and output indicators and a composite index to rank districts. This study explores the use of hierarchical cluster analysis for analysing and presenting district health systems performance data and compares this approach with the use of the league table in Uganda. Ministry of Health and district plans and reports, and published documents were used to provide information on the development and utilization of the Uganda district league table. Quantitative data were accessed from the Ministry of Health databases. Statistical analysis using SPSS version 20 and hierarchical cluster analysis, utilizing Wards' method was used. The hierarchical cluster analysis was conducted on the basis of seven clusters determined for each year from 2003 to 2010, ranging from a cluster of good through moderate-to-poor performers. The characteristics and membership of clusters varied from year to year and were determined by the identity and magnitude of performance of the individual variables. Criticisms of the league table include: perceived unfairness, as it did not take into consideration district peculiarities; and being oversummarized and not adequately informative. Clustering organizes the many data points into clusters of similar entities according to an agreed set of indicators and can provide the beginning point for identifying factors behind the observed performance of districts. Although league table ranking emphasize summation and external control, clustering has the potential to encourage a formative, learning approach. More research is required to shed more light on factors behind observed performance of the different clusters. Other countries especially low-income countries that share many similarities with Uganda can learn from these experiences.

How Has the Free Obstetric Care Policy Impacted Unmet Obstetric Need in a Rural Health District in Guinea?

Introduction

In 2010, the Ministry of Health (MoH) of Guinea introduced a free emergency obstetric care policy in all the public health facilities of the country. This included antenatal checks, normal delivery and Caesarean section.

Objective

This study aims at assessing the changes in coverage of obstetric care according to the Unmet Obstetric Need concept before (2008) and after (2012) the implementation of the free emergency obstetric care policy in a rural health district in Guinea.

Methods

We carried out a descriptive cross-sectional study involving the retrospective review of routine programme data during the period April to June 2014.

Results

No statistical difference was observed in women’s sociodemographic characteristics and indications (absolute maternal indications versus non-absolute maternal indications) before and after the implementation of the policy. Compared to referrals from health centers of patients, direct admissions at hospital significantly increased from 49% to 66% between 2008 and 2012 (p = 0.001). In rural areas, this increase concerned all maternal complications regardless of their severity, while in urban areas it mainly affected very severe complications. Compared to 2008, there were significantly more Major Obstetric Interventions for Maternal Absolute Indications in 2012 (p<0.001). Maternal deaths decreased between 2008 and 2012 from 1.5% to 1.1% while neonatal death increased from 12% in 2008 to 15% in 2012.

Conclusion

The implementation of the free obstetric care policy led to a significant decrease in unmet obstetric need between 2008 and 2012 in the health district of Kissidougou. However, more research is needed to allow comparisons with other health districts in the country and to analyse the trends.

Using the unmet obstetric needs indicator to map inequities in life-saving obstetric interventions at the local health care system in Kenya

BACKGROUND

Developing countries with high maternal mortality need to invest in indicators that not only provide information about how many women are dying, but also where, and what can be done to prevent these deaths. The unmet Obstetric Needs (UONs) concept provides this information. This concept was applied at district level in Kenya to assess how many women had UONs and where the women with unmet needs were located.

METHODS

A facility based retrospective study was conducted in 2010 in Malindi District, Kenya. Data on pregnant women who underwent a major obstetric intervention (MOI) or died in facilities that provide comprehensive Emergency Obstetric Care (EmOC) services in 2008 and 2009 were collected. The difference between the number of women who experienced life threatening obstetric complications and those who received care was quantified. The main outcome measures in the study were the magnitude of UONs and their geographical distribution.

RESULTS

566 women in 2008 and 724 in 2009 underwent MOI. Of these, 185 (32.7%) in 2008 and 204 (28.1%) in 2009 were for Absolute Maternal Indications (AMI). The most common MOI was caesarean section (90%), commonly indicated by Cephalopelvic Disproportion (CPD)-narrow pelvis (27.6% in 2008; 26.1% in 2009). Based on a reference rate of 1.4%, the overall MOI for AMI rate was 1.25% in 2008 and 1.3% in 2009. In absolute terms, 22 (11%) women in 2008 and 12 (6%) in 2009, who required a life saving intervention failed to get it. Deficits in terms of unmet needs were identified in rural areas only while urban areas had rates higher than the reference rate (0.8% vs. 2.2% in 2008; 0.8% vs. 2.1% in 2009).

CONCLUSIONS

The findings, if used as a proxy to maternal mortality, suggest that rural women face higher risks of dying during pregnancy and childbirth. This indicates the need to improve priority setting towards ensuring equity in access to life saving interventions for pregnant women in underserved areas.

Barriers to emergency obstetric care services: accounts of survivors of life threatening obstetric complications in Malindi District, Kenya

Introduction

Pregnancy-related mortality and morbidity in most low and middle income countries can be reduced through early recognition of complications, prompt access to care and appropriate medical interventions following obstetric emergencies. We used the three delays framework to explore barriers to emergency obstetric care (EmOC) services by women who experienced life threatening obstetric complications in Malindi District, Kenya.

Methods

A facility-based qualitative study was conducted between November and December 2010. In-depth interviews were conducted with 30 women who experienced obstetric “near miss” at the only public hospital with capacity to provide comprehensive EmOC services in the district.

Resuls

Findings indicate that pregnant women experienced delays in making decision to seek care and in reaching an appropriate care facility. The “first” delay was due to lack of birth preparedness, including failure to identify a health facility for delivery services regardless of antenatal care and to seek care promptly despite recognition of danger signs. The “second” delay was influenced by long distance and inconvenient transport to hospital. These two delays resulted in some women arriving at the hospital too late to save the life of the unborn baby.

Conclusion

Delays in making the decision to seek care when obstetric complications occur, combined with delays in reaching the hospital, contribute to ineffective treatment upon arrival at the hospital. Interventions to reduce maternal mortality and morbidity must adequately consider the pre-hospital challenges faced by pregnant women in order to influence decision making towards addressing the three delays.

Maternal postpartum morbidity in Marrakech: what women feel what doctors diagnose?

Background

Information about postpartum maternal morbidity in developing countries is limited and often based on information obtained from hospitals. As a result, the reports do not usually reflect the true magnitude of obstetric complications and poor management at delivery. In Morocco, little is known about obstetric maternal morbidity. Our aim was to measure and identify the causes of postpartum morbidity 6 weeks after delivery and to compare women’s perception of their health during this period to their medical diagnoses.

Methods

We did a cross-sectional study of all women, independent of place of delivery, in Al Massira district, Marrakech, from December 2010 to March 2012. All women were clinically examined 6 to 8 weeks postpartum for delivery-related morbidities. We coupled a clinical examination with a questionnaire and laboratory tests (hemoglobin).

Results

During postpartum consultation, 44% of women expressed at least one complaint. Complaints related to mental health were most often reported (10%), followed by genital infections (8%). Only 9% of women sought treatment for their symptoms before the postpartum visit. Women who were aged ≥30 years, employed, belonged to highest socioeconomic class, and had obstetric complications during birth or delivered in a private facility or at home were more likely to report a complaint. Overall, 60% of women received a medical diagnosis related to their complaint, most of which were related to gynecological problems (22%), followed by laboratory-confirmed anemia (19%). Problems related to mental health represented only 5% of the diagnoses. The comparative analysis between perceived and diagnosed morbidity highlighted discrepancies between complaints that women expressed during their postpartum consultation and those they received from a physician.

Conclusions

A better understanding of postpartum complaints is one of the de facto essential elements to ensuring quality of care for women. Sensitizing and training clinicians in mental health services is important to respond to women’s needs and improve the quality of maternal care.

Family planning in Guinea: a need for better public commitment

OBJECTIVE

To describe the evolution of family planning (FP) in Guinea and to identify strengths, weaknesses, opportunities and threats of the current FP programme.

METHODS

Descriptive study of the evolution of FP in Guinea between 1992 and 2010. First, national laws as well as health policies and strategic plans related to reproductive health and family planning were reviewed. Second, FP indicators were extracted from the Guinean Demographic and Health Surveys (1992, 1999 and 2005). Third, FP services, sources of supply and data on FP funding were analysed.

RESULTS

Laws, policies and strategic plans in Guinea are supportive of FP programme and services. Public and private actors are not sufficiently coordinated. The general government expenditure on health has remained stable at 6-7% between 2005 and 2011 despite a doubling of total expenditures on health, and contraceptives are supplied by foreign aid. Modern contraceptive prevalence slightly increased from 1.5% in 1992 to 6.8% in 2005 among women aged 15-49.

CONCLUSION

A stronger national engagement in favour of repositioning FP should result in improved government funding of the FP programme and the promotion of long-acting and permanent methods.

Existence and functionality of emergency obstetric care services at district level in Kenya: theoretical coverage versus reality

Background

The knowledge on emergency obstetric care (EmOC) is limited in Kenya, where only partial data from sub-national studies exist. The EmOC process indicators have also not been integrated into routine health management information system to monitor progress in safe motherhood interventions both at national and lower levels of the health system. In a country with a high maternal mortality burden, the implication is that decision makers are unaware of the extent of need for life-saving care and, therefore, where to intervene. The objective of the study was to assess the actual existence and functionality of EmOC services at district level.

Methods

This was a facility-based cross-sectional study. Data were collected from 40 health facilities offering delivery services in Malindi District, Kenya. Data presented are part of the “Response to accountable priority setting for trust in health systems” (REACT) study, in which EmOC was one of the service areas selected to assess fairness and legitimacy of priority setting in health care. The main outcome measures in this study were the number of facilities providing EmOC, their geographical distribution, and caesarean section rates in relation to World Health Organization (WHO) recommendations.

Results

Among the 40 facilities assessed, 29 were government owned, seven were private and four were voluntary organisations. The ratio of EmOC facilities to population size was met (6.2/500,000), compared to the recommended 5/500,000. However, using the strict WHO definition, none of the facilities met the EmOC requirements, since assisted delivery, by vacuum or forceps was not provided in any facility. Rural–urban inequities in geographical distribution of facilities were observed. The facilities were not providing sufficient life-saving care as measured by caesarean section rates, which were below recommended levels (3.7% in 2008 and 4.5% in 2009). The rates were lower in the rural than in urban areas (2.1% vs. 6.8%; p < 0.001 ) in 2008 and (2.7% vs. 7.7%; p < 0.001) in 2009.

Conclusions

The gaps in existence and functionality of EmOC services revealed in this study may point to the health system conditions contributing to lack of improvements in maternal survival in Kenya. As such, the findings bear considerable implications for policy and local priority setting.

How to develop a theory-driven evaluation design? Lessons learned from an adolescent sexual and reproductive health programme in West Africa

Background

This paper presents the development of a study design built on the principles of theory-driven evaluation. The theory-driven evaluation approach was used to evaluate an adolescent sexual and reproductive health intervention in Mali, Burkina Faso and Cameroon to improve continuity of care through the creation of networks of social and health care providers.

Methods/design

Based on our experience and the existing literature, we developed a six-step framework for the design of theory-driven evaluations, which we applied in the ex-post evaluation of the networking component of the intervention. The protocol was drafted with the input of the intervention designer. The programme theory, the central element of theory-driven evaluation, was constructed on the basis of semi-structured interviews with designers, implementers and beneficiaries and an analysis of the intervention's logical framework.

Discussion

The six-step framework proved useful as it allowed for a systematic development of the protocol. We describe the challenges at each step. We found that there is little practical guidance in the existing literature, and also a mix up of terminology of theory-driven evaluation approaches. There is a need for empirical methodological development in order to refine the tools to be used in theory driven evaluation. We conclude that ex-post evaluations of programmes can be based on such an approach if the required information on context and mechanisms is collected during the programme.

Effects of a Skilled Care Initiative on pregnancy-related mortality in rural Burkina Faso

OBJECTIVE

The aim of this paper is to assess to what extent a Skilled Care Initiative (SCI) was associated with pregnancy-related mortality in Ouargaye district, Burkina Faso.

METHODS

We used a quasi-experimental design to compare pregnancy-related mortality within the intervention district (health facility areas covered by the SCI vs. areas not covered) and between the intervention district (Ouargaye) and a comparison district (Diapaga). Population-based data were used to examine differences in pregnancy-related mortality levels, their determinants and how they related to uptake of care, as well as examining contexts and mechanisms of pregnancy-related deaths that occurred. Data analyses included descriptive statistics, univariate and multivariate regression analyses.

RESULTS

The main risk factors for pregnancy-related mortality in rural Burkina Faso were age (extreme ages of reproductive period), low coverage of antenatal care and low institutional delivery. The introduction of the SCI, as implemented within the study reference period, had no appreciable effect on pregnancy-related mortality.

CONCLUSION

Although the SCI was conceptually well designed and implemented, structural constraints may have limited its effectiveness for reducing pregnancy-related mortality within its period of implementation. Lessons have been identified which might enable similar skilled attendance strategies to make their full potential impact on pregnancy-related mortality in remote and rural settings.

Reducing financial barriers to emergency obstetric care: experience of cost-sharing mechanism in a district hospital in Burkina Faso

OBJECTIVE

To describe the implementation of a cost-sharing system for emergency obstetric care in an urban health district of Ouagadougou, Burkina Faso and analyse its results after 1 year of activity.

METHODS

Service availability and use, service quality, knowledge of the cost-sharing system in the community and financial viability of the system were measured before and after the system was implemented. Different sources of data were used: community survey, anthropological study, routine data from hospital files and registers and specific data collected on major obstetric interventions (MOI) in all the hospitals utilized by the district population. Direct costs of MOI were collected for each patient through an individual form and monitored during the year 2005. Rates of MOI for absolute maternal indications (AMI) were calculated for the period 2003-2005.

RESULTS

The direct cost of a MOI was on average 136US$, including referral cost. Through the cost-sharing system this amount was shared between families (46US$), health centres (15US$), Ministry of Health (38US$) and local authority (37US$). The scheme was started in January 2005. The rate of cost recovery was 91.3% and the balance at the end of 2005 was slightly positive (4.7% of the total contribution). The number of emergency referrals by health centres increased from 84 in 2004 to 683 in 2005. MOI per 100 expected births increased from 1.95% in 2003 to 3.56% in 2005 and MOI for AMI increased from 0.75% to 1.42%.

CONCLUSIONS

The dramatic increase in MOI suggests that the cost-sharing scheme decreased financial and geographical barriers to emergency obstetric care. Other positive effects on quality of care were documented but the sustainability of such a system remains uncertain in the dynamic context of Burkina Faso (decentralization).

Costs and coverage of reproductive health interventions in three rural refugee-affected districts, Uganda

BACKGROUND

Uganda has hosted an estimated 200,000 refugees in post-emergency phase settlements interspersed within host communities since 1990. However, refugee health service runs parallel to host in most refugee-affected districts. The process of integration of health services began in 1999.

OBJECTIVE

To estimate and compare the costs and coverage of reproductive health (RH) interventions in refugee and host populations in three rural West Nile refugee-affected districts of Uganda.

METHODS

Data on costs of RH interventions were collected through a survey in 38/116 (33%) health facilities (3 public hospitals and 35 health centres). Data on coverage of RH interventions were collected from all 116 health facilities in the three rural refugee-affected districts for 2 years, 2003 and 2004.

RESULTS

The costs and coverage of RH interventions significantly varied between population categories and among levels of refugee and host health facilities. Per capita cost of health care is 2.7 times higher for the refugee than the host population (US$13.12 vs. US$4.85). The cost per RH intervention is higher in the refugee than in the host health system (US$3.02 vs. US$2.73). Significantly more refugees attend antenatal care [99.4% (95% CI, 97.5-100) vs. 53.5% (53.22-53.78); P < 0.0001]. The proportion of births in health facilities was significantly greater among refugees [37.3% (36.12-38.48) vs. 15.2% (15.01-15.39); P < 0.05]. Major obstetrical interventions for absolute maternal indications were significantly more frequent among refugees than the host population living in the same region [1.02% (0.79-1.25) vs. 0.85% (0.80-0.90); P < 0.05].

CONCLUSIONS

Our study has shown higher costs and coverage in refugee than host health services. The findings suggest policy recommendations for improving the capacity, financing, organization and the performance of host health system in the refugee-affected settings.

Reliability of data on caesarean sections in developing countries

OBJECTIVE

To examine the reliability of reported rates of caesarean sections from developing countries and make recommendations on how data collection for surveys and health facility-based studies could be improved.

METHODS

Population-based rates for caesarean section obtained from two sources: Demographic and Health Surveys (DHS) and health facility-based records of caesarean sections from the Unmet Obstetric Need Network, together with estimates of the number of live births, were compared for six developing countries. Sensitivity analyses were conducted using several different definitions of the caesarean section rate, and the rates obtained from the two data sources were compared.

FINDINGS

The DHS rates for caesarean section were consistently higher than the facility-based rates. However, in three quarters of the cases, the facility-based rates for caesarean sections fell within the 95% confidence intervals for the DHS estimate.

CONCLUSION

The importance of the differences between these two series of rates depends on the analyst's perspective. For national and global monitoring, DHS data on caesarean sections would suffice, although the imprecision of the rates would make the monitoring of trends difficult. However, the imprecision of DHS data on caesarean sections precludes their use for the purposes of programme evaluation at the regional level.

Measuring unmet obstetric need at district level: how an epidemiological tool can affect health service organization and delivery

A national retrospective survey on the unmet need for major obstetric surgery using the Unmet Obstetric Need Approach was carried out in Mali in 1999. In Koutiala, the district health team decided to carry on the monitoring of the met need for several years in order to assess their progress over time. The first prospective study, for 1999, estimated that more than 100 women in need of obstetric care never reached the hospital and probably died as a consequence. This surprising result shocked the district health team and the resulting increased awareness of service deficits triggered operational measures to tackle the problem. The Unmet Obstetric Need study in Koutiala district was implemented without financial support and only limited external technical back-up. The appropriation of the study by the district team for solving local problems of access to obstetric care may have contributed to the success of the experience. Used as a health service management tool, the study and its results started a dialogue between the hospital staff and both health centre staff and community representatives. This had not only the effect of triggering consideration of coverage, but also of quality of obstetric care.
