The Evidence
26In the proceedings before Commissioner Tabbaa and before the Commission as presently constituted Officer Redmond emphatically denied the intravenous delivery of fentanyl to Mr B.
27Officer Redmond put that he was shocked by the allegation, felt intimidated and nervous in the investigative process and had little or no recall of the actual events, reconstructing details when questioned about them.
28Officer Redmond was a very nervous witness in these proceedings and before Commissioner Tabbaa, which she was moved to remark upon (TR 3/2/11 p 11).
29Officer Redmond first explained his lack of recall to the investigation putting: "why would I recall this event, I attend hundreds of such calls".
30In cross examination before Commissioner Tabbaa on 2 February 2012, Officer Redmond said (TR 2/2/11 pp 15, 20, 21, 46, 47, 54):
'Q. And then indeed at page 60 of the affidavit, in the transcript you were asked a question about whether you'd give fentanyl IV if it was allowed and you say yes, you probably would, but at the moment -and then you say, going back to the issue of the cannula, "Look, if I went to the bother of cannulating a patient, if I think they're in enough pain, I'm going to give them morphine. Why would I go to all the hassle of diluting fentanyl to give it intravenously when I've got morphine in my kit, it's ludicrous." Do you see that?
A. What page is that?
Q. Page 60, lines 12 to 76.
A. Yes, I accept that.
Q. But you did go to the bother of cannulating him, didn't you?
A. Yes.
Q. So why didn't you administer morphine?
A. Because he'd already had methoxyflurane and methoxyflurane and fentanyl, when given together, is very, very effective. Morphine has some significant side effects. If fentanyl does the job intranasally, I don't see the point in giving morphine and risking more severe side effects.
Q. So you didn't see any point to giving him morphine?
A. Not unless it was absolutely necessary.
Q. Because of the -because the dose of methoxyflurane and together with the fentanyl, was an effective regime?
A. Yes.
Q. Well, if it's such an effective regime, why cannulate?
A. I had cannulated a lot of my patients, particularly if I was going to give them S8s. Cannulation prior to the administration of a drug that can cause respiratory depression is a really good idea in case they need to have that respiratory depression reversed.
Q. That wasn't your explanation in the interview with Ms Leech, was it?
A. This was all sprung on me, I didn't have any time to ponder the questions. It was just immediate answers to immediate questions.
Q. You needed some time to get your story straight, did you?
A. I needed some - I would have liked to have had more time to ponder the questions.
... ...
Q. So what you're saying is that when you're administering fentanyl, you regularly also insert a cannula in order to deal with any adverse reaction?
A. Occasionally, if I deem it necessary.
Q. I see. So what was it about Mr B's situation which made you deem it necessary to insert a cannula?
A. Two reasons. One, he had a back injury. If he was going to vomit from either the fentanyl or morphine, if that were necessary, then the first thing he would do would be to exacerbate his back injury. I wanted to be able to prevent that if he started to become nauseous. Secondly, if he required stronger analgesic, ie. Morphine intravenously and had an adverse reaction to that, I would need to be able to administer naloxone to counteract that.
Q. So realty you're dealing with the situation where there might be an adverse reaction to morphine?
A. Possible, that's half of the answer, yes.
Q. And it's more likely that there would be an adverse reaction to morphine than to fentanyl, isn't it?
A. Statistically, yes.
Q. So going back to what you said at the interview before Ms Leech, the reason that you cannulated Mr B on your evidence is because you thought you might be giving him morphine down the track?
A. Again may I say that these questions were sprung on me, I didn't have no idea what the case, what the allegation or the details were. I've had more time to think about that. The reason I cannulated him was as I just said, twofold.
Q. And so you've now got this actual recollection of something that happened in November 2009 which you did not have in December 2009?
A. No, because I'd had no reason to even think about it.
Q. All right. it's possible, isn't it, that in thinking about it and pondering it, your recollection may have become suited to the case that you want to put to this commission?
A. I guess hypothetically that is possible, yes.
Q. You see, when you were closer to the event and you told Ms Leech that the reason for the cannulation was in case he needed morphine, you didn't remember what you now remember in your affidavit of 2 December 2010, a year later, that he told you, Mr B told you, that morphine made him sick in the past. At paragraph 33(vi) of your affidavit on page 5.
A. Yes, okay.
Q. Where did that recollection come from, Mr Redmond?
A. Long -having had a long time to think about this job with notice.
Q. Right. So are you sure about that?
A. Yes.
... ...
Q. Mr Redmond, you say that you offered him -that he said that morphine had made him sick in the past, yes?
A. Yes.
Q. And your evidence is that your view is that fentanyl is a much better drug that morphine?
A. (No verbal reply)
Q. If you like, you can have a look at paragraph 50 of your affidavit, page 8, to refresh your memory.
A. Yes, that is correct.
Q. And you have a particular interest and knowledge of fentanyl, don't you?
A. I found it quite fascinating.
Q. So here you have a patient who has been given what you describe as an effective regimen of methoxyflurane and fentanyl and yet you still cannulate him in case he needs morphine in circumstances where he has told you morphine makes him sick?
A. Mm-hmm.
Q. Is that what you're asking the commission to accept?
A. Yes, it's not unusual practice.
Q. That's your usual practice?
A. Yes, I said it is not unusual practice.
Q. So is it regular or not unusual or occasional?
A. For me personally? Occasional.
......
Q. B, sorry. What did he say?
A. To be honest, I don't recollect exactly what he said.
Q. What did he say roughly?
A. I offered him fentanyl or morphine, explained what both those were and he said, I've had morphine -no, I can't remember exactly what he said, but he indicated to me that morphine had made him sick in the past. So I gave him fentanyl, inquired further after the fentanyl on the effects of morphine on him, decided it was a sensitivity, a transient sensitivity, which is what the sensitivities are, the nausea and the itchiness. It's transient, it goes away in a couple of minutes.
Q. So that's what it was-
A. Obviously what his side effects were.
Q. So that's what he said to you, that it was itchiness and nausea?
A. Yes, he said, "It made me sick". I asked him, "What sort of sickness?" "Oh, I just felt like throwing up". Okay, so I judged it to be a sensitivity rather than an allergy.
Q. Sorry, he said, "I just felt like throwing up"?
A. Yes.
Q. When did he mention itchiness?
A. I was talking about the common side effects of morphine administration intravenously.
Q. Right.
A. He may have said that, he may not have said that, I don't recall exactly what he said.
Q. Well, you certainly didn't recall when you had an interview with Ms Leech several weeks after the event in December 2009?
A. No.
Q. You made no mention of this conversation in that interview, did you?
A. No.
Q. In fact it wasn't until you filed your evidence in these proceedings, a year after the event, that you mentioned that he had a reaction or was made sick by morphine?
A. That is right.
Q. And you still haven't included in that affidavit any reference to this attempt by you to check on the very nature of the sickness that the morphine induced?
A. No.
Q. That's something you just recalled as you were sitting here today?
A. I cannot say that I distinctly recall that conversation, no, but that would be my normal process of inquiring or questioning of a patient regarding his medical history. I can't recall the conversation I've had with any patient.
Q. Well, if that's your conversation about the medical history, should you not have recorded that in the part of the form which records the medical history?
A. Not unless it was particularly significant, no.
Q. So we could expect that if there had been a sensitivity recorded in the column under allergies, there would be some comment on the form to make it relevant or show that it was significant?
A. Yes.
... ...
Q. Mr Redmond, did you cannulate Mr B before or after you administered the fentanyl?
A. To be honest, I don't recall.
Q. You don't recall now?
A. I don't recall at all.
Q. You gave evidence to the commission earlier this morning that you cannulated him prior to administering fentanyl?
A. Prior to administering the fentanyl?
Q. That is right.
A. It's possible. I may have cannulated him whilst he was trying the methoxyflurane, but more likely it would have been after the administration of fentanyl, but it's possible either way. I don't recall specifically.
Q. I see. You've said that since the interview -sorry, I think you've given evidence that you didn't have time to ponder the circumstances of Mr B's incident prior to attending the interview with Ms Leech on 18 December 2009. Do you remember giving that evidence?
A. True, yes.
Q. And you say that since then, you have had time to ponder the circumstances?
A. Yes.
Q. And if there was any difference between what you said to Ms Leech then and the evidence you're giving to the commission now, presumably that is because you have now had a chance to ponder the circumstances?
A. That is correct.
31To the best of his recollection and reconstructions Officer Redmond's evidence leads to a conclusion that on entering the residence of the patient he:
(1)assessed him;
(2)delivered methoxyflurane orally in the prescribed manner referred to as a "green whistle";
(3)administered fentanyl nasally;
(4)cannulated the patient;
(5)flushed the canula;
(6)escorted the patient to the ambulance and transferred him to hospital.
32Officer Redmond provided all of the direct treatment. Officer Horgan assisted by providing materials and medications and preparing the stretcher.
33Officer Horgan's evidence is that she recalled preparing the stretcher after Mr B's treatment was complete but had no recollection of whether she or Mr Redman cleaned up the used materials (TR 3/2/11 pp73, 74).
34Officer Redmond completed the Patient Health Care Form (PHCR) J930203 (Attach. A Exhibit P3, Officer Horgan's Statement) which Officer Horgan co-signed. In this Form Officer Hogan and Officer Redmond agreed on the report. Officer Horgan subsequently deposed that she felt compelled to sign off on all of the paperwork for the job as presented to her by Officer Redmond, putting (Ex 3, para 8):
"..even though I did not see any additional Fentanyl administered to the patient or the left over Fentanyl discarded."
35 Officer Horgan's version of events is not inconsistent with that of Officer Redmond except for the assertion that he administered only part of the fentanyl nasally and mixed the remainder with the saline solution used to flush the cannula, thus illegally and improperly administering fentanyl intravenously.
36Officer Redmond denies Officer Horgan's assertion that he said: " I will show you a little trick"; and: "I will explain in the car"; and further denies that there was any conversation in the ambulance of the type put by Officer Horgan.
37Officer Redmond's evidence is that cannulation is a routine procedure. Mr Prince pursued this evidence on the basis that "routine" meant every time a patient is treated, and relied upon records to support a view that it did not occur frequently and was not "routine" as Officer Redmond deposed, thus attacking the credibility of his evidence.
38My observation is that Officer Redmond was using the term "routine" in a number of ways; cannulation is essential (therefore routine) where any substance is to be delivered intravenously, however, the decision to cannulate a patient depends on the attending officer's assessment of the patient, and where a decision is made to cannulate, the process of inserting the cannula is routine.
39Officer Horgan's evidence supports this proposition, replying to questions by Mr Edwards in cross examination before the Commissioner (TR 3/2/11 p54):
Q. And its permissible, is it not, for an Ambulance Officer, if he expects to use morphine as treatment, in anticipation of that, to cannulate?
A. To use morphine, yes.
Q. That is correct isn't it. So if an officer holds a belief that in his view the patient may require morphine, its appropriate to cannulate?
A. Yes.
40Later, in further cross examination (supra at p61) Officer Horgan accepted that it is quite proper to cannulate a patient in anticipation of using morphine.
41There is conjecture as to whether Mr B informed Officer Redmond that he was allergic to morphine or preferred something other than morphine, or made a choice to have fentanyl other than morphine.
42Officer Redmond is clear in his recollection, so far as he remembers any of the events of the incident, that Mr B told him that morphine had made him sick in the past.
43Mr Prince sought to bring evidence from Mr and Mrs B to challenge this last statement. Leave to admit the evidence was refused.
44The fact is Mr B was given fentanyl. The evidence already established that Officer Redmond had little or no direct recollection of the particular event.
45The existence or otherwise of the discussion between Mr B and Officer Redmond and which of their evidence on that point is accepted is not material to the larger question of conduct, nor in my assessment to the credibility of Officer Redmond's evidence.
46It is not necessary to resolve any contest in the evidence between Mr and Mrs B and Officer Redmond to address the primary question of whether Officer Redmond did or did not administer fentanyl intravenously.
47The disparity between Officer Redmond's evidence and that attributed to Mr B whether Mr B expressed a preference for fentanyl due to morphine making him nauseous, or whether Mr B made no such election and had no prior experience with morphine, does not detract from the evidence of either as to the sequence of events in the administration of fentanyl and cannulation. On this point Mr B's evidence supports Officer Redmond.
48The Full Bench on appeal expressed the view that the information provided by Mr and Mrs B to the investigation should have been taken into account by Commissioner Tabbaa in her decision.
49That information is found in Mr Rochford's evidence (Annex. 13 to Ex P8) in the form of a record of interview of Mr B by the investigating officer, Ms Leitch which took place on 15 December 2009.
50Mr B confirmed that he was on the floor in the lounge room when the ambulance arrived at his residence. Mr B informed Ms Leitch that he could not recall all of the events due to the pain he was suffering, but did recall that his blood pressure was checked and that there was some conversation prior to him being given a green tube with some medication which seemed to relax him and relieve the pain slightly. Mr B recalled that the ambulance officers then checked for feeling in his legs before putting some sort of medication in his nose and asking him to inhale, and the insertion of the cannula in the back of his right hand.
51Mr B told Ms Leitch that he was unsure if the cannula was inserted prior to the nasal medication, however, his wife had told him that the nasal medication was administered first. Mr B recalled the cannula being flushed, and that the pain gradually resided to the point that he could walk with assistance to the stretcher.
52Mr B put that before the ambulance arrived he was shaking uncontrollably, especially in his legs, which worried his wife. Mr B told Ms Leitch that the shaking stopped at some time during the ambulance officers attending to him.
53Mr B further told Ms Leitch that he recalled his wife was standing some two to three meters away from him with a clear line of sight to him from the elbows down, but his head was probably out of her view.
54The direct evidence of Officer Horgan before the Commission is a handwritten note dated Sunday, 8 November 2009 (Exhibit E4) and the cross examination of Officer Horgan before the Commissioner (TR 3/2/11 pp45-95).
55The allegations put by Officer Horgan in exhibit E4 go beyond the events involving treatment to Mr B. Officer Horgan states therein:
"I was driving for the day we attended a house in baulkham hills. The pt was on the floor in the loungeroom not far from the front door. Pt had a Hx of back pain and had hurt is [sic] sciatic nerve that day. Pt was started on methoxy I asked redo if he wanted morphine or fentanyl. He said fentanyl but also put the torniqet on as well. While I drew up 0.4ml of Fentanyl redo poped in a cannula. I wondered why. I put the atomiser on and gave it to redo. He took it off and said "I'll show you a little trick". He diluted the Fentanyl gave an unknown amount IV. He then gave another unknown amount IN. He said "I'll explain later". We took the pt to norwest private. When we were sitting in the car afterwards redo tried to explain how the dose works saying "he had measured out the doses before to know what he was giving, he also said that the way we give it is crap. It's surposed to be given IV, he stated that he had spoken to a doctor about it who he claims also thinks we should give it IV. He also stated "I trust you not to say anything" and "you just have to be careful who you do it infront of". He also stated that by giving it IN as well if the pt was ever asked they would say yes I had it IN. I then said "thats just to cover your arse" he said "well yeah".
Later that day we also backed up a responder who had given an old lady 10mgs of morphine for a #NOF. While driving I heard noise from the back and realised redo had given fentanyl as well. I cannot prove how it was given.
Woodbury Village
On our first night shift early in the am we went to another lady with back pain. The job was near wentworthville leagues club. The lady was given methoxyflurane first. Redo couldn't find any veins so the fentanyl was given IN. However I did not see redo discard the rest of it at Westmead.
On our last night we did a fat (illegible) job. A girl called ......... She had been at hawkesbury and was going to Westmead. She had IV fluids running already from hosp staff. I had swapped and was driving the truck because redo was tired. During the trip he gave fentanyl. I could not see clearly enough wether this was given IV or IN. When we were cleaning up at Westmead he said "this dosent have a good sharps container in it so I will get rid of this (the fentanyl) inside. I never saw it being discarded.
56In cross examination before Commissioner Tabbaa Officer Horgan confirmed that she made the handwritten notes contemporaneously as a record and aide to recollection, however, she did not take the notes with her to the interview with Ms Leitch or advise her of their existence (TR 3/2/11 pp68-70).
57Officer Horgan denied that she made the notes at a later date when this was put to her by Mr Edwards in cross examination.
58During the course of investigation Ms Leitch also interviewed Officers Wayne Blackburn and Ian Bird on 8 December 2009. The records of interview are found as an attachment to Mr Rochford's affidavit (Annex. F to Ex P8).
59It is appropriate to note here that Ms Leitch did not give any evidence. Messrs Voyzey, McCarthy and Rochford were required for cross examination. Mr Edwards sought to introduce the records of interview of Officers Blackburn and Bird which was met with a reply that they were not to be called by the Respondent and their record of interview is in evidence.
60At the time of interview Mr Blackburn was a Chief Paramedic Level 2 and had worked with Officer Redmond for about six weeks at Riverstone Ambulance Station between 5 September to 7 November 2009.
61Mr Blackburn was questioned by Ms Leitch in respect to 15 occasions fentanyl was administered to a patient, either by himself or Officer Redmond, in that period. Mr Blackburn could not recall the precise details of every event, however he could recall some and confirmed that on all occasions fentanyl was delivered intranasally.
62The information provided by Mr Blackburn was that the fentanyl phials and Mucosal Atomiser Devices (MAD) were kept in separate packages in the same place and that the officer administering fentanyl would be responsible for disposal of used items and writing up any discard of the drug, and for disposal of used implements at the hospital to which the patient was transported.
63Mr Blackburn could not recall any discussions with Officer Redmond concerning the method of delivery of fentanyl, putting that he was trained and accredited in the use of the drug and had only ever known of intranasal delivery.
64At the time of interview Mr Bird was an Intensive Care Paramedic based at Riverstone Ambulance Station. Mr Bird worked with Officer Redmond for five weeks in the period 2 August to 6 September 2009.
65Mr Bird was asked, by reference to Patient Health Care Records, to comment on four cases in which fentanyl was administered to a patient whilst he was working with Officer Redmond.
66Mr Bird could not recall the details of all of the events but could recall some instances.
67Mr Bird was clear that his practice was for disposal of used phials and equipment to be witnessed by his roster partner.
68Mr Bird informed Ms Leitch that he formed the view that Officer Redmond had a leaning toward fentanyl over morphine as he had spent some time following his change from level 5 to T1 using fentanyl without having access to morphine, had become used to it and had good results.
69When asked if there had been a discussion whether fentanyl might be better delivered intravenously than intranasally, Mr Bird put that it has been a topic of conversation for him and he certainly wondered why an intravenous regime was not kept. Mr Bird informed that he had no specific recollection but thought he could have discussed it with Officer Redmond, though never the prospect of departing from intranasal delivery in practice.
70Also attached to Mr Rochford's affidavit (Annex. G Ex P8) is a copy of the handwritten notes of interview taken by Ms Dawson on the occasion Mr Rochford, Mr Holland, Assistant Divisional Manager Gately and
Ms Dawson interviewed Officer Redmond on 12 April 2010.
71These notes record Officer Redmond's denial of the allegations when they were first made; his concern that the initial interview process was heavily biased toward the complainant and against him; and his explanation that he was vague in the initial interview because there was nothing to recall.
