Systematic review of strategies to increase access to health services among children over five in low- and middle-income countries

BACKGROUND

The populations of many low- and middle-income countries (LMIC) are young. Despite progress made towards achieving Universal Health Coverage and remarkable health gains, evidence suggests that many children in LMIC are still not accessing needed healthcare services. Delayed or lack of access to health services can lead to a worsening of health and can in turn negatively impact a child's ability to attend school, and future employment opportunities.

METHODS

We conducted a systematic review to assess the effectiveness of interventions aimed at increasing access to health services for children over 5 years in LMIC settings. Four electronic databases were searched in March 2017. Studies were included if they evaluated interventions that aimed to increase: healthcare utilisation, immunisation uptake and compliance with medication/referral. Randomised controlled trials and non-randomised study designs were included in the review. Data extraction included study characteristics, intervention type and measures of access to health services for children above 5 years of age. Study outcomes were classified as positive, negative, mixed or null in terms of their impact on access outcomes.

RESULTS

Ten studies met the criteria for inclusion in the review. Interventions were evaluated in Nicaragua (1), Brazil (1), Turkey (1), India (1), China (1), Uganda (1), Ghana (1), Nigeria (1), South Africa (1) and Swaziland (1). Intervention types included education (2), incentives (1), outreach (1), SMS/phone call reminders (2) and multicomponent interventions (4). All evaluations reported positive findings on measured health access outcomes; however, the quality and strength of evidence were mixed.

CONCLUSION

This review provides evidence of the range of interventions that were used to increase healthcare access for children above 5 years old in LMIC. Nevertheless, further research is needed to examine each of the identified intervention types and the influence of contextual factors, with robust study designs. There is also a need to assess the cost-effectiveness of the interventions to inform decision-makers on which are suitable for scale-up in their particular contexts.

Neurodevelopmental outcome of HIV-exposed but uninfected infants in the Mother and Infants Health Study, Cape Town, South Africa

OBJECTIVES

To compare neurodevelopmental outcomes of HIV-exposed uninfected (HEU) and HIV-unexposed uninfected (HUU) infants in a peri-urban South African population. HEU infants living in Africa face unique biological and environmental risks, but uncertainty remains regarding their neurodevelopmental outcome. This is partly due to lack of well-matched HUU comparison groups needed to adjust for confounding factors.

METHODS

This was a prospective cohort study of infants enrolled at birth from a low-risk midwife obstetric facility. At 12 months of age, HEU and HUU infant growth and neurodevelopmental outcomes were compared. Growth was evaluated as WHO weight-for-age, length-for-age, weight-for-length and head-circumference-for-age Z-scores. Neurodevelopmental outcomes were evaluated using the Bayley scales of Infant Development III (BSID) and Alarm Distress Baby Scale (ADBB).

RESULTS

Fifty-eight HEU and 38 HUU infants were evaluated at 11-14 months of age. Performance on the BSID did not differ in any of the domains between HEU and HUU infants. The cognitive, language and motor scores were within the average range (US standardised norms). Seven (12%) HEU and 1 (2.6%) HUU infant showed social withdrawal on the ADBB (P = 0.10), while 15 (26%) HEU and 4 (11%) HUU infants showed decreased vocalisation (P = 0.06). There were no growth differences. Three HEU and one HUU infant had minor neurological signs, while eight HEU and two HUU infants had macrocephaly.

CONCLUSIONS

Although findings on the early neurodevelopmental outcome of HEU infants are reassuring, minor differences in vocalisation and on neurological examination indicate a need for reassessment at a later age.
