What works? Interventions for maternal and child undernutrition and survival.

Background
Lay health workers (LHWs) are widely used to provide care for a broad range of health issues. Little is known, however, about the effectiveness of LHW interventions.

Objectives
To assess the effects of LHW interventions in primary and community health care on maternal and child health and the management of infectious diseases.

Search methods
For the current version of this review we searched The Cochrane Central Register of Controlled Trials (including citations uploaded from the EPOC and the CCRG registers) (The Cochrane Library 2009, Issue 1 Online) (searched 18 February 2009); MEDLINE, Ovid (1950 to February Week 1 2009) (searched 17 February 2009); MEDLINE In-Process & Other Non-Indexed Citations, Ovid (February 13 2009) (searched 17 February 2009); EMBASE, Ovid (1980 to 2009 Week 05) (searched 18 February 2009); AMED, Ovid (1985 to February 2009) (searched 19 February 2009); British Nursing Index and Archive, Ovid (1985 to February 2009) (searched 17 February 2009); CINAHL, Ebsco 1981 to present (searched 07 February 2010); POPLINE (searched 25 February 2009); WHOLIS (searched 16 April 2009); Science Citation Index and Social Sciences Citation Index (ISI Web of Science) (1975 to present) (searched 10 August 2006 and 10 February 2010). We also searched the reference lists of all included papers and relevant reviews, and contacted study authors and researchers in the field for additional papers.

Selection criteria
Randomised controlled trials of any intervention delivered by LHWs (paid or voluntary) in primary or community health care and intended to improve maternal or child health or the management of infectious diseases. A 'lay health worker' was defined as any health worker carrying out functions related to healthcare delivery, trained in some way in the context of the intervention, and having no formal professional or paraprofessional certificate or tertiary education degree. There were no restrictions on care recipients.

Data collection and analysis
Two review authors independently extracted data using a standard form and assessed risk of bias. Studies that compared broadly similar types of interventions were grouped together. Where feasible, the study results were combined and an overall estimate of effect obtained.

Main results
Eighty-two studies met the inclusion criteria. These showed considerable diversity in the targeted health issue and the aims, content, and outcomes of interventions. The majority were conducted in high income countries (n = 55) but many of these focused on low income and minority populations. The diversity of included studies limited meta-analysis to outcomes for four study groups. These analyses found evidence of moderate quality of the effectiveness of LHWs in promoting immunisation childhood uptake (RR 1.22, 95% CI 1.10 to 1.37; P = 0.0004); promoting initiation of breastfeeding (RR = 1.36, 95% CI 1.14 to 1.61; P < 0.00001), any breastfeeding (RR 1.24, 95% CI 1.10 to 1.39; P = 0.0004), and exclusive breastfeeding (RR 2.78, 95% CI 1.74 to 4.44; P <0.0001); and improving pulmonary TB cure rates (RR 1.22 (95% CI 1.13 to 1.31) P <0.0001), when compared to usual care. There was moderate quality evidence that LHW support had little or no effect on TB preventive treatment completion (RR 1.00, 95% CI 0.92 to 1.09; P = 0.99). There was also low quality evidence that LHWs may reduce child morbidity (RR 0.86, 95% CI 0.75 to 0.99; P = 0.03) and child (RR 0.75, 95% CI 0.55 to 1.03; P = 0.07) and neonatal (RR 0.76, 95% CI 0.57 to 1.02; P = 0.07) mortality, and increase the likelihood of seeking care for childhood illness (RR 1.33, 95% CI 0.86 to 2.05; P = 0.20). For other health issues, the evidence is insufficient to draw conclusions regarding effectiveness, or to enable the identification of specific LHW training or intervention strategies likely to be most effective.

Authors' conclusions
LHWs provide promising benefits in promoting immunisation uptake and breastfeeding, improving TB treatment outcomes, and reducing child morbidity and mortality when compared to usual care. For other health issues, evidence is insufficient to draw conclusions about the effects of LHWs.

Lay health workers in primary and community health care for maternal and child health and the management of infectious diseases.

Objective To review the literature on breastfeeding initiation and duration and to delineate effective strategies for promoting positive breastfeeding behaviors. Data Sources Computerized searches on MEDLINE, CINAHL, and the Cochrane Library. Study Selection Articles from indexed journals relevant to the objective and published after 1990 (except for classic findings) were reviewed. Although a myriad of pertinent articles was located, referenced citations were limited to three per point. When article selection was required for a specific point, preferences were given to (a) randomized controlled trials; (b) meta-analyses; (c) studies with the largest, most representative samples; and (d) investigations conducted in North America. Data Extraction Data were extracted and organized under the following headings: benefits of breastfeeding, breastfeeding initiation and duration, personal characteristics, attitudinal and intrapersonal characteristics, hospital policies and intrapartum experience, sources of support, breastfeeding interventions, and review implications. Data Synthesis Although the health benefits of breastfeeding are well documented and initiation rates have increased over the past 20 years, most mothers wean before the recommended 6-months postpartum because of perceived difficulties with breastfeeding rather than due to maternal choice. Women least likely to breastfeed are those who are young, have a low income, belong to an ethnic minority, are unsupported, are employed full-time, decided to breastfeed during or late in pregnancy, have negative attitudes toward breastfeeding, and have low confidence in their ability to breastfeed. Support from the mother's partner or a nonprofessional greatly increases the likelihood of positive breastfeeding behaviors. Health care professionals can be a negative source of support if their lack of knowledge results in inaccurate or inconsistent advice. Furthermore, a number of hospital routines are potentially detrimental to breastfeeding. Although professional interventions that enhance the usual care mothers receive increase breastfeeding duration to 2 months, these supportive strategies have limited long-term effects. Peer support interventions also promote positive breastfeeding behaviors and should be considered. Conclusions A promising intervention is the complementation of professional services with peer support from a mother experienced in breastfeeding. This lay support appears to be an effective intervention with socially disadvantaged women.

Breastfeeding Initiation and Duration: A 1990-2000 Literature Review

BACKGROUND
Lay health workers (LHWs) are widely used to provide care for a broad range of health issues. However, little is known about the effectiveness of LHW interventions.


OBJECTIVES
To assess the effects of LHW interventions in primary and community health care on health care behaviours, patients' health and wellbeing, and patients' satisfaction with care.


SEARCH STRATEGY
We searched the Cochrane Effective Practice and Organisation of Care and Consumers and Communication specialised registers (to August 2001); the Cochrane Central Register of Controlled Trials (to August 2001); MEDLINE (1966- August 2001); EMBASE (1966-August 2001); Science Citations (to August 2001); CINAHL (1966-June 2001); Healthstar (1975-2000); AMED (1966-August 2001); the Leeds Health Education Effectiveness Database and the reference lists of articles.


SELECTION CRITERIA
Randomised controlled trials of any intervention delivered by LHWs (paid or voluntary) in primary or community health care and intended to promote health, manage illness or provide support to patients. A 'lay health worker' was defined as any health worker carrying out functions related to health care delivery; trained in some way in the context of the intervention; and having no formal professional or paraprofessional certificated or degreed tertiary education. There were no restrictions on the types of consumers.


DATA COLLECTION AND ANALYSIS
Two reviewers independently extracted data onto a standard form and assessed study quality. Studies that compared broadly similar types of interventions were grouped together. Where feasible, the results of included studies were combined and an estimate of effect obtained.


MAIN RESULTS
Forty three studies met the inclusion criteria, involving more than 210,110 consumers. These showed considerable diversity in the targeted health issue and the aims, content and outcomes of interventions. Most were conducted in high income countries (n=35), but nearly half of these focused on low income and minority populations (n=15). Study diversity limited meta-analysis to outcomes for five subgroups (n=15 studies) (LHW interventions to promote the uptake of breast cancer screening, immunisation and breastfeeding promotion [before two weeks and between two weeks and six months post partum] and to improve diagnosis and treatment for selected infectious diseases). Promising benefits in comparison with usual care were shown for LHW interventions to promote immunisation uptake in children and adults (RR=1.30 [95% CI 1.14, 1.48] p=0.0001) and LHW interventions to improve outcomes for selected infectious diseases (RR=0.74 [95% CI 0.58, 0.93) p=0.01). LHWs also appear promising for breastfeeding promotion. They appear to have a small effect in promoting breast cancer screening uptake when compared with usual care. For the remaining subgroups (n=29 studies), the outcomes were too diverse to allow statistical pooling. We can therefore draw no general conclusions on the effectiveness of these subgroups of interventions.


AUTHORS' CONCLUSIONS
LHWs show promising benefits in promoting immunisation uptake and improving outcomes for acute respiratory infections and malaria, when compared to usual care. For other health issues, evidence is insufficient to justify recommendations for policy and practice. There is also insufficient evidence to assess which LHW training or intervention strategies are likely to be most effective. Further research is needed in these areas.

Lay health workers in primary and community health care : Cochrane systematic review. Commentary

BACKGROUND: There is extensive evidence of important health risks for infants and mothers related to not breastfeeding. In 2003, the World Health Organization recommended that infants be breastfed exclusively until six months of age, with breastfeeding continuing as an important part of the infant's diet until at least two years of age. However, current breastfeeding rates in many countries do not reflect this recommendation. OBJECTIVES: To describe forms of breastfeeding support which have been evaluated in controlled studies, the timing of the interventions and the settings in which they have been used.To examine the effectiveness of different modes of offering similar supportive interventions (for example, whether the support offered was proactive or reactive, face-to-face or over the telephone), and whether interventions containing both antenatal and postnatal elements were more effective than those taking place in the postnatal period alone.To examine the effectiveness of different care providers and (where information was available) training.To explore the interaction between background breastfeeding rates and effectiveness of support. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register (29 February 2016) and reference lists of retrieved studies. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials comparing extra support for healthy breastfeeding mothers of healthy term babies with usual maternity care. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS: This updated review includes 100 trials involving more than 83,246 mother-infant pairs of which 73 studies contribute data (58 individually-randomised trials and 15 cluster-randomised trials). We considered that the overall risk of bias of trials included in the review was mixed. Of the 31 new studies included in this update, 21 provided data for one or more of the primary outcomes. The total number of mother-infant pairs in the 73 studies that contributed data to this review is 74,656 (this total was 56,451 in the previous version of this review). The 73 studies were conducted in 29 countries. Results of the analyses continue to confirm that all forms of extra support analyzed together showed a decrease in cessation of 'any breastfeeding', which includes partial and exclusive breastfeeding (average risk ratio (RR) for stopping any breastfeeding before six months 0.91, 95% confidence interval (CI) 0.88 to 0.95; moderate-quality evidence, 51 studies) and for stopping breastfeeding before four to six weeks (average RR 0.87, 95% CI 0.80 to 0.95; moderate-quality evidence, 33 studies). All forms of extra support together also showed a decrease in cessation of exclusive breastfeeding at six months (average RR 0.88, 95% CI 0.85 to 0.92; moderate-quality evidence, 46 studies) and at four to six weeks (average RR 0.79, 95% CI 0.71 to 0.89; moderate quality, 32 studies). We downgraded evidence to moderate-quality due to very high heterogeneity.We investigated substantial heterogeneity for all four outcomes with subgroup analyses for the following covariates: who delivered care, type of support, timing of support, background breastfeeding rate and number of postnatal contacts. Covariates were not able to explain heterogeneity in general. Though the interaction tests were significant for some analyses, we advise caution in the interpretation of results for subgroups due to the heterogeneity. Extra support by both lay and professionals had a positive impact on breastfeeding outcomes. Several factors may have also improved results for women practising exclusive breastfeeding, such as interventions delivered with a face-to-face component, high background initiation rates of breastfeeding, lay support, and a specific schedule of four to eight contacts. However, because within-group heterogeneity remained high for all of these analyses, we advise caution when making specific conclusions based on subgroup results. We noted no evidence for subgroup differences for the any breastfeeding outcomes. AUTHORS' CONCLUSIONS: When breastfeeding support is offered to women, the duration and exclusivity of breastfeeding is increased. Characteristics of effective support include: that it is offered as standard by trained personnel during antenatal or postnatal care, that it includes ongoing scheduled visits so that women can predict when support will be available, and that it is tailored to the setting and the needs of the population group. Support is likely to be more effective in settings with high initiation rates. Support may be offered either by professional or lay/peer supporters, or a combination of both. Strategies that rely mainly on face-to-face support are more likely to succeed with women practising exclusive breastfeeding.

Support for healthy breastfeeding mothers with healthy term babies

When infants afflicted with diarrhea were brought to the Hospital of the International Centre for Diarrhoeal Disease Research Bangladesh (ICDDRB) in Dhaka Bangladesh 125 mother-infant pairs received at least three lactation counseling sessions on the benefits of exclusive breast feeding. Researchers compared data on these 125 pairs with data on 125 other mother-infant pairs who were also at ICDDRB due to diarrhea but did not receive any counseling. Infants in the intervention group had a shorter hospital stay than those in the control group (4.3 vs. 3 days; p < .001). The controls left before diarrhea ended while cases were discharged after diarrhea ended. At discharge mothers in the intervention group were more likely than controls to be predominantly breast feeding (breast milk plus oral rehydration solution [ORS]) (30% vs. 19%) as well as exclusively breast feeding (60% vs. 6%) (p < .001). Two weeks after discharge when ORS was stopped mothers in the intervention group were more likely to be exclusively breast feeding than those in the control group (75% vs. 8%) while those in the control group were more likely to bottle feed than cases (49% vs. 12%) (p < .001). Infants in the control group were more likely to have another episode of diarrhea within 2 weeks than those in the intervention group (15 vs. 4; p = .05; odds ratio = 2.92). These findings indicate that individual lactation counseling had a strong influence on mothers to begin exclusive breast feeding during hospitalization and to continue to do so at home. Thus staff at maternal and child health facilities should integrate lactation counseling into their program to improve infant feeding practices.

Breast-feeding counselling in a diarrhoeal disease hospital.

During the hospitalization in the Dhaka hospital of the international Centre for Diarrhoeal Disease Research, Bangladesh, of a group of partially breast-fed infants aged 1-12 weeks who had been admitted with acute diarrhoea, their mothers were individually counselled by breast-feeding counsellors to start exclusive breast-feeding. The counselling was repeated 1 week later at home, and the women's infant-feeding practices were evaluated 2 weeks after their infants had been discharged from hospital. A total of 25% of the mothers failed to breast-feed exclusively despite having been counselled. The case studies of these mothers illustrate that although they generally complained about having "insufficient breast milk" various factors such as domineering grandmothers, lack of financial support by their husbands, too much housework, or disinterest contributed to their failure to breast-feed exclusively. While family support is essential for all lactating mothers, women with familial or financial problems require special attention and extra counselling sessions so that they can be helped to identify how to achieve and sustain exclusive breast-feeding.

Reasons for Failure of Breast-Feeding Counselling: Mothers' Perspectives in Bangladesh

Se adiestro a consejeras en materia de lactancia materna para que dieran asesoramiento a las madres de lactantes parcialmente amamantados y hospitalizados por diarrea, con el fin de lograr que las madres iniciaran la lactancia materna exclusiva durante su permanencia en el hospital. Se asigno de forma aleatoria a lactantes (n = 250) de 12 meses de edad o menos a un grupo de intervencion y a un grupo testigo. Las madres del grupo de intervencion fueron asesoradas individualmente por las consejeras, mientras que las madres del grupo testigo recibieron solo la educacion sanitaria impartida en grupo rutinariamente. Durante el seguimiento que hicieron las consejeras en el hogar una semana mas tarde, solo las madres del grupo de intervencion fueron asesoradas. A las 2 semanas de su egreso, todas las madres fueron evaluadas en terminos de sus practicas de amamantamiento en el hogar. En cuanto a los 125 pares de madres e hijos que habia en cada grupo, 60% de las madres del grupo de intervencion alimentaban a sus hijos al pecho exclusivamente en el momento del egreso, en comparacion con solo 6% de las madres del grupo testigo (P < 0,001); 2 semanas mas tarde, estos porcentajes subieron a 75 y 8 en el grupo de intervencion y en el grupo testigo, respectivamente (P < 0,001). Sin embargo, 49% de las madres del grupo testigo volvieron a alimentar a sus hijos con biberon, en comparacion con 12% de las madres del grupo de intervencion (P < 0,001). Por consiguiente, la orientacion individual tuvo un efecto favorable en las madres, ya que hizo que iniciaran la lactancia materna exclusiva durante la hospitalizacion y que la siguieran practicando en el hogar. Los centros de salud maternoinfantil deben incluir la orientacion sobre lactancia materna como parte integral de sus programas para mejorar las practicas de alimentacion de los lactantes.
