Integrated maternal and infant health care in the postpartum period in a poor neighborhood in Santiago, Chile

Targeted health and social care interventions for women and infants who are disproportionately impacted by health inequalities in high-income countries: a systematic review

BACKGROUND

Disadvantaged populations (such as women from minority ethnic groups and those with social complexity) are at an increased risk of poor outcomes and experiences. Inequalities in health outcomes include preterm birth, maternal and perinatal morbidity and mortality, and poor-quality care. The impact of interventions is unclear for this population, in high-income countries (HIC). The review aimed to identify and evaluate the current evidence related to targeted health and social care service interventions in HICs which can improve health inequalities experienced by childbearing women and infants at disproportionate risk of poor outcomes and experiences.

METHODS

Twelve databases searched for studies across all HICs, from any methodological design. The search concluded on 8/11/22. The inclusion criteria included interventions that targeted disadvantaged populations which provided a component of clinical care that differed from standard maternity care.

RESULTS

Forty six index studies were included. Countries included Australia, Canada, Chile, Hong Kong, UK and USA. A narrative synthesis was undertaken, and results showed three intervention types: midwifery models of care, interdisciplinary care, and community-centred services. These intervention types have been delivered singularly but also in combination of each other demonstrating overlapping features. Overall, results show interventions had positive associations with primary (maternal, perinatal, and infant mortality) and secondary outcomes (experiences and satisfaction, antenatal care coverage, access to care, quality of care, mode of delivery, analgesia use in labour, preterm birth, low birth weight, breastfeeding, family planning, immunisations) however significance and impact vary. Midwifery models of care took an interpersonal and holistic approach as they focused on continuity of carer, home visiting, culturally and linguistically appropriate care and accessibility. Interdisciplinary care took a structural approach, to coordinate care for women requiring multi-agency health and social services. Community-centred services took a place-based approach with interventions that suited the need of its community and their norms.

CONCLUSION

Targeted interventions exist in HICs, but these vary according to the context and infrastructure of standard maternity care. Multi-interventional approaches could enhance a targeted approach for at risk populations, in particular combining midwifery models of care with community-centred approaches, to enhance accessibility, earlier engagement, and increased attendance.

Effect of health facility linkage with community using postnatal card on postnatal home visit coverage and newborn care practices in rural Ethiopia: A controlled quasi-experimental study design

Background

Postnatal home visit has the potential to improve maternal and newborn health, but it remains as a missed opportunity in many low-and middle-income countries. This study examines the effect of health extension worker administered postnatal card combined with health facility strengthening intervention on postnatal home visit coverage, newborn care practices, and knowledge of newborn danger signs in rural Ethiopia.

Methods

We employed quasi-experimental design using controlled before-and-after study in intervention and comparison districts of rural Tigray, northern Ethiopia. Training of health extension workers (HEWs) on postnatal home visit (PNHV), training of healthcare providers on maternal and newborn care, and capacity building of healthcare authorities on leadership, management and governance together with health system strengthening were the implemented interventions. Baseline (n = 705) and end line (n = 980) data were collected from mothers who delivered a year before the commencement of the actual data collection in the respective surveys. We used difference-in-differences (DiD) analysis to assess the effect of the intervention on PNHV coverage, essential newborn care practices and maternal knowledge of newborn danger signs.

Results

A total of 1685 (100%) mothers participated in this study. In all districts, more than 1/3^rd of the mothers 633(37.57%) were in the age of 30–39 years. The difference-in-differences estimator showed an average of 23.5% increase in coverage of PNHVs within three days (DiD, p<0.001) and the provision of most postnatal contents significantly increased in the intervention district in the end line survey. The knowledge of at least three danger signs increased by 13.6% (p = 0.012).The DiD estimator showed an average of 27.6% increase to check the mothers for heavy bleeding (DiD, p = 0.011). This study also revealed that the checking of maternal blood pressure increased from 5.8% to 11.8% in the comparison districts and from 9.4% to 93.3% in the intervention district. The difference-in-differences estimator result showed a 9% difference in clean cord care practices among the participants (p = 0.025), 12.2% in skin to skin care (p = 0.022), and borderline significant increase in early initiation of breastfeeding (10.5%, p = 0.051).

Conclusion

We conclude that the intervention package was effective in improving the coverage of PNHV, increase in knowledge of newborn danger sign and essential newborn care practices. Hence, further strengthening the linkages between health facilities and community is imperative to improve the coverage of essential lifesaving maternal and newborn care services by HEWs at home.

“Mothers will be lucky if utmost receive a single scheduled postnatal home visit”: An exploratory qualitative study, Northern Ethiopia

Background

Postnatal home visits (PNHVs) have been endorsed as strategy for delivery of postnatal care (PNC) to reduce newborn mortality and improve maternal outcomes. Despite the important role of the Health Extension Workers (HEWs) in improving the overall healthcare coverage, PNHV remains as a missed opportunity in rural Ethiopia. Thus, this study aimed to explore the barriers and facilitators of scheduled postnatal home visits in Northern Ethiopia.

Methods

We conducted an exploratory qualitative study on a total of 16 in-depth interviews with HEWs and mothers who gave birth one year prior to the study. In addition, focus group discussions were conducted with HEWs and key informant interviews were conducted with women development group leaders, supervisors, and healthcare authorities from April to June 2019 in two rural districts of Northern Ethiopia. Discussions and interviews were audio recorded and transcribed verbatim in the local language (Tigrigna) and translated into English. The translated scripts were thematically coded using Atlas ti scientific software. Field notes were also taken during the discussion and while conducting the interviews.

Results

Health system factors, community context, and individual level factors were considered as the barriers and facilitators of scheduled PNHVs. Leadership, governance, management, support and supervision, referral linkages, overwhelming workload, capacity building, logistics and supplies are the major sub-themes identified as health system factors. Physical characteristics like geographical location and topography, distance, and coverage of the catchment; and community support and participation like support from women’s development groups (WDGs), awareness of the community on the presence of the service and cultural and traditional beliefs were community contexts that affect PNHVs. Self-motivation to support and intrinsic job satisfaction were individual level factors that were considered as barriers and facilitators.

Conclusion

The finding of this study suggested that the major barriers of postnatal home visits were poor attention of healthcare authorities of the government bodies, lack of effective supervision, poor functional linkages, inadequate logistics and supplies, unrealistic catchment area coverage, poor community participation and support, and lack of motivation of HEWs. Henceforth, to achieve the scheduled PNHV in rural Ethiopia, there should be strong political commitment and healthcare authorities should provide attention to postnatal care both at facility and home with a strong controlling system.

Effects of consumers and health providers working in partnership on health services planning, delivery and evaluation

BACKGROUND

Health services have traditionally been developed to focus on specific diseases or medical specialties. Involving consumers as partners in planning, delivering and evaluating health services may lead to services that are person-centred and so better able to meet the needs of and provide care for individuals. Globally, governments recommend consumer involvement in healthcare decision-making at the systems level, as a strategy for promoting person-centred health services. However, the effects of this 'working in partnership' approach to healthcare decision-making are unclear. Working in partnership is defined here as collaborative relationships between at least one consumer and health provider, meeting jointly and regularly in formal group formats, to equally contribute to and collaborate on health service-related decision-making in real time. In this review, the terms 'consumer' and 'health provider' refer to partnership participants, and 'health service user' and 'health service provider' refer to trial participants. This review of effects of partnership interventions was undertaken concurrently with a Cochrane Qualitative Evidence Synthesis (QES) entitled Consumers and health providers working in partnership for the promotion of person-centred health services: a co-produced qualitative evidence synthesis.

OBJECTIVES

To assess the effects of consumers and health providers working in partnership, as an intervention to promote person-centred health services.

SEARCH METHODS

We searched the CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL databases from 2000 to April 2019; PROQUEST Dissertations and Theses Global from 2016 to April 2019; and grey literature and online trial registries from 2000 until September 2019.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), quasi-RCTs, and cluster-RCTs of 'working in partnership' interventions meeting these three criteria: both consumer and provider participants meet; they meet jointly and regularly in formal group formats; and they make actual decisions that relate to the person-centredness of health service(s).

DATA COLLECTION AND ANALYSIS

Two review authors independently screened most titles and abstracts. One review author screened a subset of titles and abstracts (i.e. those identified through clinical trials registries searches, those classified by the Cochrane RCT Classifier as unlikely to be an RCT, and those identified through other sources). Two review authors independently screened all full texts of potentially eligible articles for inclusion. In case of disagreement, they consulted a third review author to reach consensus. One review author extracted data and assessed risk of bias for all included studies and a second review author independently cross-checked all data and assessments. Any discrepancies were resolved by discussion, or by consulting a third review author to reach consensus. Meta-analysis was not possible due to the small number of included trials and their heterogeneity; we synthesised results descriptively by comparison and outcome. We reported the following outcomes in GRADE 'Summary of findings' tables: health service alterations; the degree to which changed service reflects health service user priorities; health service users' ratings of health service performance; health service users' health service utilisation patterns; resources associated with the decision-making process; resources associated with implementing decisions; and adverse events.

MAIN RESULTS

We included five trials (one RCT and four cluster-RCTs), with 16,257 health service users and more than 469 health service providers as trial participants. For two trials, the aims of the partnerships were to directly improve the person-centredness of health services (via health service planning, and discharge co-ordination). In the remaining trials, the aims were indirect (training first-year medical doctors on patient safety) or broader in focus (which could include person-centredness of health services that targeted the public/community, households or health service delivery to improve maternal and neonatal mortality). Three trials were conducted in high income-countries, one was in a middle-income country and one was in a low-income country. Two studies evaluated working in partnership interventions, compared to usual practice without partnership (Comparison 1); and three studies evaluated working in partnership as part of a multi-component intervention, compared to the same intervention without partnership (Comparison 2). No studies evaluated one form of working in partnership compared to another (Comparison 3). The effects of consumers and health providers working in partnership compared to usual practice without partnership are uncertain: only one of the two studies that assessed this comparison measured health service alteration outcomes, and data were not usable, as only intervention group data were reported. Additionally, none of the included studies evaluating this comparison measured the other primary or secondary outcomes we sought for the 'Summary of findings' table. We are also unsure about the effects of consumers and health providers working in partnership as part of a multi-component intervention compared to the same intervention without partnership. Very low-certainty evidence indicated there may be little or no difference on health service alterations or health service user health service performance ratings (two studies); or on health service user health service utilisation patterns and adverse events (one study each). No studies evaluating this comparison reported the degree to which health service alterations reflect health service user priorities, or resource use. Overall, our confidence in the findings about the effects of working in partnership interventions was very low due to indirectness, imprecision and publication bias, and serious concerns about risk of selection bias; performance bias, detection bias and reporting bias in most studies.

AUTHORS' CONCLUSIONS

The effects of consumers and providers working in partnership as an intervention, or as part of a multi-component intervention, are uncertain, due to a lack of high-quality evidence and/or due to a lack of studies. Further well-designed RCTs with a clear focus on assessing outcomes directly related to partnerships for patient-centred health services are needed in this area, which may also benefit from mixed-methods and qualitative research to build the evidence base.

Multilevel prenatal socioeconomic determinants of Mexican American children's weight: Mediation by breastfeeding

Objective: Mexican American (MA) children are more likely to grow up in poverty than their non-Hispanic/Latinx white peers and are at an elevated risk for early onset obesity. The current study evaluated the effects of prenatal family- and neighborhood-level disadvantage on children's weight and weight gain from 12 months through 4.5 years of age. Maternal breastfeeding duration was evaluated as a potential mechanism underlying the relation between multilevel disadvantage and weight. Methods: Data was collected from 322 low-income, MA mother-child dyads. Women reported the degree of family socioeconomic disadvantage and breastfeeding status. Neighborhood disadvantage was evaluated with census-level metrics. Children's weight and height were measured at laboratory visits. Results: Greater prenatal neighborhood disadvantage predicted higher child Body Mass Index (BMI) at 12 months, over and above family-level disadvantage; this effect remained stable through 4.5 years. Breastfeeding duration partially mediated the effect of neighborhood disadvantage on child BMI. Breastfeeding duration predicted child BMI at all timepoints. Conclusions: Maternal prenatal residence in a neighborhood with high concentrated disadvantage may place low-income, MA children at increased risk of elevated weight status during the first few years of life. Breastfeeding duration emerged as potentially modifiable pathway through which the prenatal neighborhood impacts children's early life weight.

Opportunities lost: Barriers to increasing the use of effective contraception in the Philippines

Background

In the Philippines, one in four pregnancies are unintended and 610 000 unsafe abortions are performed each year. This study explored the association between missed opportunities to provide family planning counseling, quality of counseling and its impact on utilization of effective contraception in the Philippines.

Methods

One-hundred-one nationally representative health facilities were randomly selected from five levels of the health system. Sexually-active women 18–49 years old, wanting to delay or limit childbearing, attending primary care clinics between April 24 and August 8, 2017 were included. Data on contraceptive use, counseling and availability were collected using interviews and facility assessments. Effective contraceptive methods were defined as those with rates of unintended pregnancy of less than 10 per 100 women in first year of typical use.

Findings

849 women were recruited of whom 51.1% currently used effective contraceptive methods, 20.6% were former effective method users and 28.3% had never used an effective method. Of 1664 cumulative clinic visits reported by women in the previous year, 72.6% had a missed opportunity to receive family planning counseling at any visit regardless of level of facility, with 83.7% having a missed counseling opportunity on the day of the interview. Most women (55.9%) reported health concerns about modern contraception, with 2.9% receiving counseling addressing their concerns. Only 0.6% of former users and 2.1% never-users said they would consider starting a modern contraceptive in the future. Short and long acting reversible contraceptive methods were available in 93% and 68% of facilities respectively.

Conclusions

Missed opportunities to provide family planning counseling are widespread in the Philippines. Delivery of effective contraceptive methods requires that wider legal, policy, social, cultural, and structural barriers are addressed, coupled with systems approaches for improving availability and quality of counseling at all primary health care contacts.

Strategies for improving postpartum contraceptive use: evidence from non-randomized studies

BACKGROUND

Nearly two-thirds of women in their first postpartum year have an unmet need for family planning. Adolescents often have repeat pregnancies within a year of giving birth. Women may receive counseling on family planning both antepartum and postpartum. Decisions about contraceptive use made right after counseling may differ considerably from actual postpartum use. In earlier work, we found limited evidence of effectiveness from randomized trials on postpartum contraceptive counseling. For educational interventions, non-randomized studies may be conducted more often than randomized trials.

OBJECTIVES

We reviewed non-randomized studies of educational strategies to improve postpartum contraceptive use. Our intent was to examine associations between specific interventions and postpartum contraceptive use or subsequent pregnancy.

SEARCH METHODS

We searched for eligible non-randomized studies until 3 November 2014. Sources included CENTRAL, PubMed, POPLINE, and Web of Science. We also sought current trials via ClinicalTrials.gov and ICTRP. For additional citations, we examined reference lists of relevant reports and reviews.

SELECTION CRITERIA

The studies had to be comparative, i.e., have intervention and comparison groups. The educational component could be counseling or another behavioral strategy to improve contraceptive use among postpartum women. The intervention had to include contact within six weeks postpartum. The comparison condition could be another behavioral strategy to improve contraceptive use, usual care, other health education, or no intervention. Our primary outcomes were postpartum contraceptive use and subsequent pregnancy.

DATA COLLECTION AND ANALYSIS

Two authors evaluated abstracts for eligibility and extracted data from included studies. We computed the Mantel-Haenszel odds ratio (OR) for dichotomous outcomes and the mean difference (MD) for continuous measures, both with 95% Confidence Intervals (CI). Where studies used adjusted analyses for continuous outcomes, we presented the results as reported by the investigators. Due to differences in interventions and outcome measures, we did not conduct meta-analysis. To assess the evidence quality, we used the Newcastle-Ottawa Quality Assessment Scale.

MAIN RESULTS

Six studies met our inclusion criteria and included a total of 5143 women. Of three studies with self-reported pregnancy data, two showed pregnancy to be less likely in the experimental group than in the comparison group (OR 0.48, 95% CI 0.27 to 0.87) (OR 0.60, 95% CI 0.41 to 0.87). The interventions included a clinic-based counseling program and a community-based communication project.All studies showed some association of the intervention with contraceptive use. Two showed that treatment-group women were more likely to use a modern method than the control group: ORs were 1.77 (95% CI 1.08 to 2.89) and 3.08 (95% CI 2.36 to 4.02). In another study, treatment-group women were more likely than control-group women to use pills (OR 1.78, 95% CI 1.26 to 2.50) or an intrauterine device (IUD) (OR 3.72, 95% CI 1.27 to 10.86) but less likely to use and injectable method (OR 0.23, 95% CI 0.05 to 1.00). One study used a score for method effectiveness. The methods of the special-intervention group scored higher than those of the comparison group at three months (MD 13.26, 95% CI 3.16 to 23.36). A study emphasizing IUDs showed women in the intervention group were more likely to use an IUD (OR 1.79, 95% CI 1.20 to 2.69) and less likely to use no method (OR 0.48, 95% CI 0.31 to 0.75). In another study, contraceptive use was more likely among women in a health service intervention compared to women in a community awareness program at four months (OR 1.79, 95% CI 1.40 to 2.30) or women receiving standard care at 10 to 12 months (OR 2.08, 95% CI 1.58 to 2.74). That study was the only one with a specific component on the lactational amenorrhea method (LAM) that had sufficient data on LAM use. Women in the health service group were more likely than those in the community awareness group to use LAM (OR 41.36, 95% CI 10.11 to 169.20).

AUTHORS' CONCLUSIONS

We considered the quality of evidence to be very low. The studies had limitations in design, analysis, or reporting. Three did not adjust for potential confounding and only two had sufficient information on intervention fidelity. Outcomes were self reported and definitions varied for contraceptive use. All studies had adequate follow-up periods but most had high losses, as often occurs in contraception studies.

From foundling homes to day care: a historical review of childcare in Chile

This article discusses significant changes in childcare policy and practice in Chile. We distinguish four specific periods of childcare history: child abandonment and the creation of foundling homes in the 19th century; efforts to reduce infant mortality and the creation of the health care system in the first half of the 20th century; an increasing focus on inequality and poverty and the consequences for child development in the second half of the 20th century; and, finally, the current focus on children’s social and emotional development. It is concluded that, although Chile has achieved infant mortality and malnutrition rates comparable to those of developed countries, the country bears the mark of a history of inequality and is still unable to fully guarantee the health of children from the poorest sectors of society. Recent initiatives seek to improve this situation and put a strong emphasis on the psychosocial condition of children and their families.

Outreach and integration programs to promote family planning in the extended postpartum period

BACKGROUND

WHO recommends birth spacing to improve the health of the mother and child. One strategy to facilitate birth spacing is to improve the use of family planning during the first year postpartum.

OBJECTIVES

To determine from the literature the effectiveness of postpartum family-planning programs and to identify research gaps.

SEARCH STRATEGY

PubMed and the Cochrane Central Register of Controlled Trials were systematically searched for articles published between database inception and March 2013. Abstracts of conference presentations, dissertations, and unpublished studies were also considered.

SELECTION CRITERIA

Published studies with birth spacing or contraceptive use outcomes were included.

DATA COLLECTION AND ANALYSIS

Standard abstract forms and the US Preventive Services Task Force grading system were used to summarize and assess the quality of the evidence.

MAIN RESULTS

Thirty-four studies were included. Prenatal care, home visitation programs, and educational interventions were associated with improved family-planning outcomes, but should be further studied in low-resource settings. Mother-infant care integration, multidisciplinary interventions, and cash transfer/microfinance interventions need further investigation.

CONCLUSIONS

Programmatic interventions may improve birth spacing and contraceptive uptake. Larger well-designed studies in international settings are needed to determine the most effective ways to deliver family-planning interventions.

Operations research to add postpartum family planning to maternal and neonatal health to improve birth spacing in Sylhet District, Bangladesh

BACKGROUND

Short birth intervals are associated with increased risk of adverse maternal and neonatal health (MNH) outcomes. Improving postpartum contraceptive use is an important programmatic strategy to improve the health and well-being of women, newborns, and children. This article documents the intervention package and evaluation design of a study conducted in a rural district of Bangladesh to evaluate the effects of an integrated, community-based MNH and postpartum family planning program on contraceptive use and birth-interval lengths.

INTERVENTION

The study integrated family planning counseling within 5 community health worker (CHW)-household visits to pregnant and postpartum women, while a community mobilizer (CM) led community meetings on the importance of postpartum family planning and pregnancy spacing for maternal and child health. The CM and the CHWs emphasized 3 messages: (1) Use of the Lactational Amenorrhea Method (LAM) during the first 6 months postpartum and transition to another modern contraceptive method; (2) Exclusive, rather than fully or nearly fully, breastfeeding to support LAM effectiveness and good infant breastfeeding practices; (3) Use of a modern contraceptive method after a live birth for at least 24 months before attempting another pregnancy (a birth-to-birth interval of about 3 years) to support improved infant health and nutrition. CHWs provided only family planning counseling in the original study design, but we later added community-based distribution of methods, and referrals for clinical methods, to meet women's demand.

METHODS

Using a quasi-experimental design, and relying primarily on pre/post-household surveys, we selected pregnant women from 4 unions to receive the intervention (n = 2,280) and pregnant women from 4 other unions (n = 2,290) to serve as the comparison group. Enrollment occurred between 2007 and 2009, and data collection ended in January 2013.

PRELIMINARY RESULTS

Formative research showed that women and their family members generally did not perceive birth spacing as a priority, and most recently delivered women were not using contraception. At baseline, women in the intervention and comparison groups were similar in terms of age, husband's education, religion, and parity. CHWs visited over 90% of women in both intervention and comparison groups during pregnancy and the first 3 months postpartum.

DISCUSSION

This article provides helpful intervention-design details for program managers intending to add postpartum family planning services to community-based MNH programs. Outcomes of the intervention will be reported in a future paper. Preliminary findings indicate that the package of 5 CHW visits was feasible and did not compromise worker performance. Adding doorstep delivery of contraceptives to the intervention package may enhance impact.

Strategies for integrating primary health services in low- and middle-income countries at the point of delivery

BACKGROUND

In some low- and middle-income countries, separate vertical programmes deliver specific life-saving interventions but can fragment services. Strategies to integrate services aim to bring together inputs, organisation, and delivery of particular functions to increase efficiency and people's access. We examined the evidence on the effectiveness of integration strategies at the point of delivery (sometimes termed 'linkages'), including integrated delivery of tuberculosis (TB), HIV/AIDS and reproductive health programmes.

OBJECTIVES

To assess the effects of strategies to integrate primary health care services on healthcare delivery and health status in low- and middle-income countries.

SEARCH STRATEGY

We searched The Cochrane Central Register of Controlled Trials (CENTRAL) 2010, Issue 3, part of the The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care Group Specialised Register (searched 15 September  2010); MEDLINE, Ovid (1950 to August Week 5 2010) (searched 10 September  2010); EMBASE, Ovid (1980 to 2010 Week 35) (searched 10 September  2010); CINAHL, EBSCO (1980 to present) (searched 20 September 2010); Sociological Abstracts, CSA Illumina (1952 to current) (searched 10 September  2010); Social Services Abstracts, CSA Illumina (1979 to current) (searched 10 September  2010); POPLINE (1970 to current) (searched 10 September  2010); International Bibliography of the Social Sciences, Webspirs (1951 to current) (searched 01 July 2008); HealthStar (1975 to September 2005), Cab Health (1972 to 1999), and reference lists of articles. We also searched the World Health Organization (WHOLIS) library database, handsearched relevant WHO publications, and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials, non-randomised controlled trials, controlled before and after studies, and interrupted time series analyses of integration strategies, including strengthening linkages, in primary health care services. Health services in high-income countries, private public partnerships, and hospital inpatient care were excluded as were programmes promoting the integrated management of childhood illnesses. The main outcomes were indicators of healthcare delivery, user views, and health status.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the risk of bias. The statistical results of individual studies are reported and summarised.

MAIN RESULTS

Five randomised trials and four controlled before and after studies were included. The interventions were complex.Five studies added an additional component, or linked a new component, to an existing service, for example, adding family planning or HIV counselling and testing to routine services. The evidence from these studies indicated that adding on services probably increases service utilisation but probably does not improve health status outcomes, such as incident pregnancies.Four studies compared integrated services to single, special services. Based on the included studies, fully integrating sexually transmitted infection (STI) and family planning, and maternal and child health services into routine care as opposed to delivering them as special 'vertical' services may decrease utilisation, client knowledge of and satisfaction with the services and may not result in any difference in health outcomes, such as child survival. Integrating HIV prevention and control at facility and community level improved the effectiveness of certain services (STI treatment in males) but resulted in no difference in health seeking behaviour, STI incidence, or HIV incidence in the population.

AUTHORS' CONCLUSIONS

There is some evidence that 'adding on' services (or linkages) may improve the utilisation and outputs of healthcare delivery. However, there is no evidence to date that a fuller form of integration improves healthcare delivery or health status. Available evidence suggests that full integration probably decreases the knowledge and utilisation of specific services and may not result in any improvements in health status. More rigorous studies of different strategies to promote integration over a wider range of services and settings are needed. These studies should include economic evaluation and the views of clients as clients' views will influence the uptake of integration strategies at the point of delivery and the effectiveness on community health of these strategies.

Acute lower respiratory infections in childhood: opportunities for reducing the global burden through nutritional interventions

Inadequate nutrition and acute lower respiratory infection (ALRI) are overlapping and interrelated health problems affecting children in developing countries. Based on a critical review of randomized trials of the effect of nutritional interventions on ALRI morbidity and mortality, we concluded that: (1) zinc supplementation in zinc-deficient populations prevents about one-quarter of episodes of ALRI, which may translate into a modest reduction in ALRI mortality; (2) breastfeeding promotion reduces ALRI morbidity; (3) iron supplementation alone does not reduce ALRI incidence; and (4) vitamin A supplementation beyond the neonatal period does not reduce ALRI incidence or mortality. There was insufficient evidence regarding other potentially beneficial nutritional interventions. For strategies with a strong theoretical rationale and probable operational feasibility, rigorous trials with active clinical case-finding and adequate sample sizes should be undertaken. At present, a reduction in the burden of ALRI can be expected from the continued promotion of breastfeeding and scale-up of zinc supplementation or fortification strategies in target populations.

Strategies for integrating primary health services in middle- and low-income countries at the point of delivery

BACKGROUND

Strategies to integrate primary health care aim to bring together inputs, organisation, management and delivery of particular service functions to make them more efficient, and accessible to the service user. In some middle and low income countries, services have been fragmented by separate vertical programmes established to ensure delivery of particular technologies. We examined the effectiveness of integration strategies at the point of delivery.

OBJECTIVES

To assess the effects of strategies to integrate primary health care services on producing a more coherent product and improving health care delivery and health status.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (August 2005), MEDLINE (1966 to September 2005), EMBASE (1988 to 2005), Socio Files (1974 to September 2005), Popline (1970 to September 2005), HealthStar (1975 to September 2005), Cinahl (1982 to September 2005); Cab Health (1972 to 1999), International Bibliography of the Social Sciences (1970 to 1999), and reference lists of articles. We also searched the Internet and World Health Organization (WHO) library database, hand searched relevant WHO publications and contacted experts in the field.

SELECTION CRITERIA

Randomised trials, controlled before and after studies, and interrupted time series analyses of integration strategies in primary health care services. Health services in high-income countries were excluded. The primary outcomes were indicators of health care delivery, user views on any measure of service coherence, and health status. We also sought information on comparative costs.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed study quality.

MAIN RESULTS

Three cluster randomised trials and two controlled before and after studies were included, with three types of comparison: integration by adding on an additional component to an existing service (family planning); integrated services versus single special services (for sex workers); integrated delivery systems versus a vertical service (for family planning); and packages of enhanced primary child care services (integrated management of childhood illnesses) vs. routine child care. Interventions were complex and in some studies inputs varied substantially between comparison arms. Overall, no consistent pattern emerged. Only one study attempted to assess the user's view of the service provided.

AUTHORS' CONCLUSIONS

Few studies of good quality, large and with rigorous study design have been carried out to investigate strategies to promote service integration in low and middle income countries. All describe the service supply side, and none examine or measure aspects of the demand side. Future studies must also assess the client's view, as this will influence uptake of integration strategies and their effectiveness on community health.

Strategies for integrating primary health services in middle- and low-income countries: effects on performance, costs and patient outcomes

BACKGROUND

Integration of primary health care is change to bring together inputs, organisation, management and delivery of particular service functions. Integration has been promoted in the health sector to improve the efficiency of health care delivery. The need for integration arose from perceptions that services were fragmented when delivered through separate vertical programmes. Integration is relevant to the health system at various levels, and this review is concerned with integration at the point of delivery.

OBJECTIVES

To assess the effects of strategies to integrate primary health care services on producing a more coherent product and improving health care delivery and health status, in relation to service cost, outputs, impact and user acceptability.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (August 2000), MEDLINE (1966 to September 2000), EMBASE (1988 to September 2000), Socio Files (1974 to September 2000), Popline (1970 to September 2000), HealthStar (1975 to September 2000), Cinahl (1982 to September 2000); Cab Health (1972 to 1999), International Bibliography of the Social Sciences (1970 to 1999), and reference lists of articles. We also searched the Internet and World Health Organization (WHO) library database, hand searched relevant WHO publications and contacted experts in the field.

SELECTION CRITERIA

Randomised trials, controlled before and after studies, and interrupted time series analyses of integration strategies in primary health care services. Health services in high-income countries were excluded. The primary outcomes were service outputs: productivity and coverage, impact, user acceptability and unit cost.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed study quality.

MAIN RESULTS

Four studies were included. There was no consistent pattern of benefit. Integration had a clear positive effect on the outputs in only one study; in another it had similar effects to vertical programme delivery but greater effect than the control group. In the other two studies integration resulted in negative outputs in comparison with vertical programmes, although in one of these integration performed better than the control group.

REVIEWER'S CONCLUSIONS

Few studies of good quality, large and with rigorous study design have been carried out to investigate the evidence to support integration as a style of service delivery. In fact, some studies found greater effects for vertical health care delivery. Policy makers and planners considering integration could introduce strategies, using rigorous study design, to allow further evaluation and increase the base of studies from which to draw evidence.
