DEF - FAQ0001

Q: Who is considered to be an impatient and do "Day-patients" and "Regular attender's" count as inpatients?

A: The definition used for inpatient is ‘A patient admitted to an acute trust for care and is expected to stay overnight’. However, with regards to the apportioning algorithm and the prior trust exposure questions, we also include patients who have been day-patients and have received care in an emergency assessment unit. For example, a day-patient would qualify even though the admission was not overnight. Therefore, the question “Has the patient been discharged from an elective or emergency hospital admission in the reporting trust in the last 28/84 days” is applicable to day cases since the patient would have been discharged if admitted. However, please note that for the purpose of mandatory surveillance, there is a difference between a “Day-patient” and a “Regular attender”. An example of a regular attender would be a patient in hospital for routine dialysis treatment but was not admitted during the procedure. Such cases will not qualify as a previous admission. Since outpatients are not admitted during their procedures they are not discharged and therefore the question “Has the patient been discharged from an elective or energy hospital admission in the reporting trusts in the 28/84 days?” is not applicable to them. Regarding the day case procedures, the answer depends on if the patient was admitted while during the procedure (day-patient) or not (regular attender). If it’s the former then it would qualify while the latter would not.

Q: What percentage of Pseudomonas isolates does Psuedomonas aeruginosa represent and what percent of this is multi-resistant Psuedomonas?

A: Counts of P. aeruginosa bacteraemia reported by a trust are of all cases in England. Antibiotic susceptibility is not reported under the mandatory surveillance scheme however, you can get this information from Health Protection Reports based on voluntary surveillance of laboratory reported case of P. aeruginosa bacteraemia. The most recent report is here.

GEN - FAQ0003

Q: Regarding Gram-negative data collection. Please can you explain why permanent pacemaker and implantable cardioverter-defibrillator is included in the intravascular device category rather than the in the cardiovascular?

A: For the primary focus of infection, the option “Intravascular device” is for when an intravascular device is the confirmed (perhaps by a tip culture) source of infection. However, the “Cardiovascular or vascular” option is for when there is no confirmation but the vascular system is the suspected primary focus of infection based on the consultant or clinical microbiologist’s best opinion or assessment.

The latter option has two type, with and without prosthetic materials. These are for vascular system as the suspected primary focus, with the presence or absence of a prosthetic material. In the case where there is a prosthetic material, it would differ from the “Intravascular device” option because this material/device is not the confirmed source.

The options are to differentiate between a confirmed and suspected primary focus of infection.

Q: Does the HCAI DCS capture national data for MRSA bacteraemia in neonatal units across the country?

A: Unfortunately, we do not collect MRSA bacteraemia data specific to neonates. We do however, collect specialty information, but this may data may not be fully completed. We have produced rates for paediatric units in our most recent Quarterly Epidimiological Commentary which may be of some interest to you.

GEN - FAQ0005

Q: Are NHS Trusts expected to collect data from the hospital stay (the time between admission and diagnosis) and the whole 28 days in the community?

A: Yes. This includes any treatment within 28 days. The Trust will need to report Risk Factor data during the hospital stay. Please note that the Risk factor tab remains unlocked for up to a year after the case has been entered to allow this data to be entered. A new CCG data entry role has been created to allow the CCG colleagues to enter this information.

GEN - FAQ0006

Q: We are using a two-step algorithm for C. difficile, testing. Should we report all samples tested via this algorithm, or just the ones tested for C. difficile toxin after testing positive on the screening test?

A: Your trust should report all those screened (PCR/GDH) regardless of result (positive/negative).
