A cost-effective analysis conducted by Edwine Barasa and colleagues estimates that a complex intervention aimed at improving quality of pediatric care would be affordable and cost-effective in Kenya.
To improve care for children in district hospitals in Kenya, a multifaceted approach employing guidelines, training, supervision, feedback, and facilitation was developed, for brevity called the Emergency Triage and Treatment Plus (ETAT+) strategy. We assessed the cost effectiveness of the ETAT+ strategy, in Kenyan hospitals. Further, we estimate the costs of scaling up the intervention to Kenya nationally and potential cost effectiveness at scale.
Methods and Findings
Our cost-effectiveness analysis from the provider's perspective used data from a previously reported cluster randomized trial comparing the full ETAT+ strategy (n = 4 hospitals) with a partial intervention (n = 4 hospitals). Effectiveness was measured using 14 process measures that capture improvements in quality of care; their average was used as a summary measure of quality. Economic costs of the development and implementation of the intervention were determined (2009 US$). Incremental cost-effectiveness ratios were defined as the incremental cost per percentage improvement in (average) quality of care. Probabilistic sensitivity analysis was used to assess uncertainty. The cost per child admission was US$50.74 (95% CI 49.26–67.06) in intervention hospitals compared to US$31.1 (95% CI 30.67–47.18) in control hospitals. Each percentage improvement in average quality of care cost an additional US$0.79 (95% CI 0.19–2.31) per admitted child. The estimated annual cost of nationally scaling up the full intervention was US$3.6 million, approximately 0.6% of the annual child health budget in Kenya. A “what-if” analysis assuming conservative reductions in mortality suggests the incremental cost per disability adjusted life year (DALY) averted by scaling up would vary between US$39.8 and US$398.3.
Improving quality of care at scale nationally with the full ETAT+ strategy may be affordable for low income countries such as Kenya. Resultant plausible reductions in hospital mortality suggest the intervention could be cost-effective when compared to incremental cost-effectiveness ratios of other priority child health interventions.

According to latest global estimates from UNICEF, 7.6 million children currently die every year before they reach five years of age. Half of these deaths occur in children in sub-Saharan Africa and tragically, most of these deaths are due to a few treatable and preventable diseases, such as pneumonia, malaria, and diarrhea, for which effective interventions are already available. In order to meet the target of the 4th Millennium Development Goal—which aims to reduce the under-five child mortality rate by two-thirds from 1990 levels by 2015—delivering these interventions is essential.
In Kenya, the under-five child mortality rate must be reduced by half from its 2008 level in order to meet the Millennium Development Goal (MDG) target and so improving the management of serious child illness might help achieve this goal. A study published last year in PLoS Medicine described such an approach and included the development and implementation of evidence-based clinical practice guidelines linked to health worker training, follow-up supervision, performance feedback, and facilitation in eight district hospitals in Kenya.
Why Was This Study Done?
In the study mentioned above, the researchers compared the implementation of various processes of care in intervention and control hospitals at baseline and 18 months later and found that performance improved more in the intervention hospitals than in the control hospitals. However, while this strategy was effective at improving the quality of health care, it is unclear whether scaling up the approach would be a good use of limited resources. So in this study, the same researchers performed a cost-effectiveness analysis (which they conducted alongside the original trial) of their quality improvement intervention and estimated the costs and effects of scaling up this approach to cover the entire population of Kenya.
What Did the Researchers Do and Find?
In order to perform the cost part of the analysis, the researchers collected the relevant information on costs by using clinical and accounting record reviews and interviews with those involved in developing and implementing the intervention. The researchers evaluated the effectiveness part of the analysis by comparing the implementation of their improved quality of care strategy as delivered in the intervention hospitals with the partial intervention as delivered in the control hospitals by calculating the mean percentage improvement in the 14 process of care indicators at 18 months. Finally, the researchers calculated the costs of scaling up the intervention by applying their results to the whole of Kenya—121 hospital facilities with an estimated annual child admission rate of 2,000 per facility.
The researchers found that the quality of care (as measured by the process of care indicators) was 25% higher in intervention hospitals than in control hospitals, while the cost per child admission was US$50.74 in intervention hospitals compared to US$31.1 in control hospitals. The researchers calculated that each percentage improvement in the average quality of care was achieved at an additional cost of US$0.79 per admitted child. Extrapolating these results to all of Kenya, the estimated annual cost of scaling up the intervention nationally was US$3.6 million, about 0.6% of the annual child health budget in Kenya.
What Do These Findings Mean?
The findings of this cost-effectiveness analysis suggests that a comprehensive quality improvement intervention is effective at improving standards of care but at an additional cost, which may be relatively cost effective compared with basic care if the improvements observed are associated with decreases in child inpatient mortality. The absolute costs for scaling up are comparable to, or even lower than, costs of other, major child health interventions. As the international community is giving an increasing focus to strengthening health systems, these findings provide a strong case for scaling up this intervention, which improves quality of care and service provision for the major causes of child mortality, in rural hospitals throughout Kenya and other district hospitals in sub-Saharan Africa.
