Q: How is topical administration of antimicrobial ointment recorded in the resident questionnaire? A: Local use of antimicrobials for cellulitis/ soft tissue/ wound infections and conjunctivitis can be reported by checking a tick box in the signs and symptoms section of the resident questionnaire. This information is NOT entered in the antimicrobial treatment data section of questionnaire. TEACHING POINT

G. Gertrude, 89-year old female has been living full time in the LTCF for over a year. She is in her bed at 8am on the survey day. She is generally well with no hospital admissions since she has been in the LTCF. She requires a wheelchair. She has no urinary catheter/no vascular catheter/ no pressure sores / no wounds. She is fully orientated and continent. RESIDENT: G. Gertrude

Three days ago she complained of pain on urination. She was otherwise well and had no temperature. Her in-house GP started her on oral ciprofloxacin 250mg twice daily (BD) for five days. Dipstick test on urine showed positive result for nitrites and Ieucocytes. A mid-stream urine sample (MSU) was sent to laboratory for culture and sensitivities three days previously. On day of the survey (8 th May 2012), G. Gertrude is feeling much better. The MSU results showed >10 5 cfu/ml E. coli, which were cefotaxime resistant and meropenem susceptible. RESIDENT: G. Gertrude

Q: Must a resident questionnaire be completed for G. Gertrude and why? A: Yes, she an eligible resident and she is showing signs/symptoms of infection and is receiving antimicrobial treatment. RESIDENT: G. Gertrude – Q & A

Q: How would you complete the antimicrobial treatment data section of the resident questionnaire for G. Gertrude? RESIDENT: G. Gertrude – Q & A

Microorganism code for E. coli (see microorganism code list) Antimicrobial resistance markers and codes (see protocol)

Q: What infection do you suspect G. Gertrude has? A: Urinary tract infection RESIDENT: G. Gertrude – Q & A

Q: How would you complete the signs and symptoms of infection section of the resident questionnaire for G. Gertrude? A: As she does not have a urinary catheter in situ the algorithm for urinary tract infection without a catheter should be completed as follows: RESIDENT: G. Gertrude – Q & A

Q: If a resident is suspected of having a urinary tract infection, what steps should you take to determine whether it is present or not? TEACHING POINTS A: - Establish if the resident has a urinary catheter or not; the signs and symptoms criteria differ for each. - Check resident’s notes for information on mid- stream urine (MSU) or catheter sample collection and culture/ susceptibilities results of same.

Q: If the microorganisms highlighted in red in the microorganism code list, e.g. E. coli, Acinetobacter baumannii etc., are isolated from a sample taken for culture, how are their susceptibilities recorded in the resident questionnaire? A: 0, 1, 2 or ? as below TEACHING POINTS

R. Romeo, 75-year old male has been a full time resident in the LTCF for two years. He is present at 8am on the survey day. He has general poor health, disorientated, bedridden, and incontinent (urinary). He has no urinary catheter/no vascular catheter/ no pressure sores / no wounds. He was admitted to hospital electively 30 days ago for a prostatectomy. RESIDENT: R. Romeo

On day of the survey (8 th May 2012) his medical notes indicate that he had passed blood in his urine in the last 24 hours and his temperature is 37.9 o C. The prescribing nurse has prescribed oral trimethoprim 200mg twice daily (BD) for three days. Laboratory results on the mid-stream urine sample were not available. A urine dipstick test had not been carried out. RESIDENT: R. Romeo

For codes see later slides RESIDENT: R. Romeo

Q: This case was deemed to be a probable urinary tract infection (for a resident without a urinary catheter). What other information would have led to a confirmed infection outcome? TEACHING POINTS A:Culture result. If the result of the mid-stream urine specimen is as follows, then a urinary tract infection can be confirmed: At least 10 5 cfu/ml of no more than 2 species of micro- organisms in a voided urine sample OR At least 10 2 cfu/ml of any number of organisms in a specimen collected by in-and-out catheter

Q: If a sample is taken for culture and susceptibilities to guide antimicrobial treatment how are the culture results recorded in the resident questionnaire? TEACHING POINTS A:The three most important isolated microorganisms should be indicated using the microorganism code list or one of the following options should be selected: _NOEXAEXAMINATION NOT (YET) DONE _NARESULTS NOT AVAILABLE _NONIDMICROORGANISM NOT IDENTIFIED _STERISTERILE EXAMINATION e.g.

_NOEXA EXAMINATION NOT DONE: no diagnostic sample taken, no microbiological examination done _NA RESULTS NOT AVAILABLE: the results of the microbiological examination are not yet available or cannot be found _NONID MICROORGANISM NOT IDENTIFIED: evidence exists that a microbiological examination has been done, but the micro-organism cannot be correctly classified _STERI STERILE EXAMINATION: a microbiological examination has been done, but the result was negative (e.g. negative culture) TEACHING POINTS

J. Juliet, 80-year old female who has been living full time in the LTCF for two years after being unable to live on her own due to the onset of dementia. She had a stroke 20 years ago but made a full recovery with no lasting affects. She is present at 8am on the survey day. She is on medication for the dementia and is also on medication to prevent strokes. She also has high blood pressure (which she is on medication for) and a mobility problem (due to a hip replacement two years ago) for which she has a walking aid. She has a history of recurrent urinary tract infection. RESIDENT: J. Juliet

She has no urinary catheter/no vascular catheter/ no pressure sores / no wounds. She is disorientated due to her dementia, but fully continent. She has had no hospital admissions in previous 6 months. Her medication regime, as prescribed by her geriatrician in his clinic, is as follows: bendroflumethiazide 2.5 mg once daily (morning), donepezil hydrochloride 10 mg once daily, oral trimethoprim 100 mg once daily. On the day of the survey (8 th May 2012) staff have not noticed any changes in her condition for at least the last two weeks. She has no dysuria, no fever, no leukocytosis and no new or increased frequency, urgency, hematuria, or suprapubic pain. RESIDENT: J. Juliet

Q: This patient is receiving antimicrobial treatment for a UTI but this is not due to current or resolved signs and symptoms. Why then is she receiving antimicrobials? TEACHING POINT A:Antimicrobial prophylaxis for the prevention of recurrent urinary tract infection.

R. Rosencrantz, 62-year old male with early onset dementia living full time in the LTCF for the last five years. He is in his bed at 8am on the survey day. He is physically well but disoriented to the reality of the world around him. – He has no idea of staff names, current affairs, the country he lives in or the day/month/year he is living in. – However, he can find his way unattended to the dining room for meals, and knows which drawer in the nurses office cigarettes are stored in. RESIDENT: R. Rosencrantz

He has had no hospital admissions since arriving in the LTCF. Over the last two days he has been urinating more often. He has no urinary catheter/no vascular catheter/ no pressure sores / no wounds and is fully continent. His temperature was taken on the morning of the survey (8 th May 2012) and was recorded as 37.6 o C. No urine sample has been sent for laboratory analysis nor has a dipstick test been carried out. RESIDENT: R. Rosencrantz

Q: Why was a resident questionnaire filled out for this resident? TEACHING POINTS A:He had increased frequency which can be suggestive of a urinary tract infection. Q: Why was a urinary tract infection not confirmed? A:This resident’s signs and symptoms did not meet the criteria necessary to confirm the presence of a urinary tract infection or be deemed a probable urinary tract infection.

Q: How would this outcome be recorded in the HALT PPS software? A:Only the information in the grey boxes of the signs and symptoms of infection section of the resident questionnaire should be reported in the software, therefore there would be no resident questionnaire completed in the software for this resident. (The urine dipstick result is only recorded in software if a UTI is confirmed/ deemed probable i.e. dipstick result alone does not need to be recorded in software) Note: All signs and symptoms must be ticked in algorithms in paper version of the resident questionnaire regardless of infection confirmation result. TEACHING POINTS

It might be useful in such cases as these to indicate on the paper resident questionnaire that no infection was confirmed/ deemed probable to inform staff when inputting data into software that this resident did not fulfill the criteria for a HAI. This must only be done if this resident is also NOT on antimicrobial treatment as if he/she is receiving antimicrobial treatment a resident questionnaire must be completed in the software.
