How do I calculate a score if some items scores are missing
If you are undertaking a research project, then those responsible for the study need to decide on a consistent approach to missing items. It is possible to estimate a score allowing for missing items, but we recommend this should not be more than 5 items – after that it is better to exclude the case.
In a clinical context clearly doing this might lead to worrying clinical interpretation e.g. if the child did not fix or follow or suck feed – these are highly significant findings in themselves and calculating an overall score would not be helpful or in the child’s interest. However, usually one missing item will not be crucial for deciding whether a child needs further follow-up or not, but it is always important to look at the overall pattern of findings and the clinical issues, not just the score. We encourage checking that the proforma is complete before the child leaves the clinic.
