Aims-To estimate the financial cost to the NHS of infant crying and sleepin
g problems in the first 12 weeks of age and to assess the cost effectivenes
s of behavioural and educational interventions aimed at reducing infant cry
ing and sleeping problems relative to usual services.
Methods-A cost burden analysis and cost effectiveness analysis were conduct
ed using data from the Crying Or Sleeping Infants (COSI) Study, a three arm
ed prospective randomised controlled trial that randomly allocated 610 moth
ers to a behavioural intervention (n = 205), an educational intervention (n
= 202), or existing services (control, n = 203). Main outcome measures wer
e annual total cost to the NHS of infant crying and sleeping problems in th
e first 12 weeks, and incremental cost per interruption free night gained f
or behavioural and educational interventions relative to central.
Results-The annual total cost to the NHS of infant crying and sleeping prob
lems in the first 12 weeks was pound 65 million (US$104 million). Increment
al costs per interruption free night gained for the behavioural interventio
n relative to control were pound0.56 (US$0.92). For the educational interve
ntion relative to control they were pound4.13 (US$6.80).
Conclusions The annual total cost to the NHS of infant crying and sleeping
problems is substantial. In the cost effectiveness analysis, the behavioura
l intervention incurred a small additional cost and produced a small signif
icant benefit at 11 and 12 weeks of age. The educational intervention incur
red a small additional cost without producing a significant benefit.
