Among ill medical patients, what is the prevalence of abnormal urinalyses that are due to the underlying medical illness, vs abnormal urinalyses due to a co-existing urinary infection(I think I recall seeing data on this, but now cannot find it)
Notes about answers

Paper by sundvall I think may have answer" I believe he was referring to this paper The Development of a Decision Tool for the Empiric Treatment of Suspected Urinary Tract Infection in Frail Older Adults: A Delphi Consensus Procedure https://www.ncbi.nlm.nih.gov/pubmed/29910137 This is in a very specific population!

- Responded 20 Jun 2019 · Unfortunately, I was unable to find anything useful. I found isolated articles discussing differential diagnosis of UTI versus conditions such as overactive bladder – but gave no figures as to the proportion. Via Twitter (I asked Twitter for help) someone suggested that it is very context specific and therefore impossible to give a general answer. Another message (DM) stated: “There are multiple conditions that affect the sensitivity and specificity of urine dip testing .... whereas direct microscopy, machine analytics and culture, will be least affected. Local laboratory facilities would be best placed to answer this question and are likely to be more situationally accurate. As with all metabolic tests they need to be taken in the medical context of the patient along with history of complaint and physical signs.” Conflict of interest declaration: None
