Abstract
BackgroundIn assessing quality of care in developing countries, retrospectively collected data are usually used given their availability. Retrospective data however suffer from such biases as recall bias and non-response bias. Comparing results obtained using prospectively and retrospectively collected data will help validate the use of the easily available retrospective data in assessing quality of care in past and future studies.MethodsProspective and retrospective datasets were obtained from a cluster randomized trial of a multifaceted intervention aimed at improving paediatric inpatient care conducted in eight rural Kenyan district hospitals by improving management of children admitted with pneumonia, malaria and diarrhea and/or dehydration. Four hospitals received a full intervention and four a partial intervention. Data were collected through 3 two weeks surveys conducted at baseline, after 6 and 18 months. Retrospective data was sampled from paediatric medical records of patients discharged in the preceding six months of the survey while prospective data was collected from patients discharged during the two week period of each survey. Risk Differences during post-intervention period of16 quality of care indicators were analyzed separately for prospective and retrospective datasets and later plotted side by side for comparison.ResultsFor the prospective data there was strong evidence of an intervention effect for 8 of the indicators and weaker evidence of an effect for one indicator, with magnitude of effect sizes varying from 23% to 60% difference. For the retrospective data, 10 process (these include the 8 indicators found to be statistically significant in prospective data analysis) indicators had statistically significant differences with magnitude of effects varying from 10% to 42%. The bar-graph comparing results from the prospective and retrospective datasets showed similarity in terms of magnitude of effects and statistical significance for all except two indicators.ConclusionMultifaceted interventions can help improve adoption of clinical guidelines and hence improve the quality of care. The similar inference reached after analyses based on prospective assessment of case management is a useful finding as it supports the utility of work based on examination of retrospectively assembled case records allowing longer time periods to be studied while constraining costs.Trial registrationCurrent Controlled Trials ISRCTN42996612.

Highlights
In assessing quality of care in developing countries, retrospectively collected data are usually used given their availability
We use prospectively collected case data to examine the effects of an intervention aimed at improving paediatric practices in Kenya and contrast these findings with those previously reported based on retrospectively collected data [6]
A total of 6302 retrospective case records were available for analysis from similar surveys
Summary
In assessing quality of care in developing countries, retrospectively collected data are usually used given their availability. Abstracting data from medical records can be preferable to prospective designs because they are less resource intensive, they can be used in exploring possible associations and can be performed at researchers’ convenience. Such data are subject to numerous sources of bias, usually have a lot of missing data especially where documentation of care is poor and it’s often difficult to establish true causal effect relationships [8]. We use prospectively collected case data to examine the effects of an intervention aimed at improving paediatric practices in Kenya and contrast these findings with those previously reported based on retrospectively collected data [6]. Our aims is both to examine the intervention effects using arguably a more robust data set and triangulate the findings with those based on retrospective case record review
