Developing audit sample sizes

[Anonymous]

Dear Brains trust,

We have been reviewing the numbers of episodes of donning and doffing required for our PPE audit.

Which made us curious to find out what formula other hospitals and departments use when developing sample sizes for audits, do you take statics into consideration when developing the numerators or use some other method?

Thanks in advance for your comments

Kind regards,

Holly

Hi Holly

It would be great to use correct statistical methods to work out a required sample size every time ( eg Basic concepts for sample size calculation: Critical step for any clinical trials! – PMC (nih.gov)), but in reality for many in-house audits we do it ends up being more “what is possible with our current resources?”, rather than what is statistically correct.

If resources were available, sure, we could aim for appropriately powered sample sizes. And if we wanted to publish our findings, we could seek funding to make sure those resources were available. But for much of what we do on a daily basis, the constraint is “how many can we collect?”.

In my opinion and experience, anyway.

Cheers
Michael
