Description of intervention(s) / exposure
All patients with fractured neck of femur should receive regional anaesthesia in the emergency department. At present, three different techniques are in use in our department. This study will compare the analgesic efficacy of these three interventions:
1) Femoral nerve block
2) Fascia iliaca compartment block
3) Pericapsular nerve group block

There is no assignment of therapy. This is an observational study of current practice in the emergency department. It is expected that most or all nerve blocks will use 75 - 150 mg of ropivacaine in 20 - 40 mL. However alternative anaesthetic drug/dose/adjuncts may be used at the discretion of the clinician and her/his usual practice.

Patients will be observed for 12 hours after their nerve block or until checked in the operating theatre, whichever is sooner.

Comparator / control treatment
The intervention of primary interest is the pericapsular nerve group block. The femoral nerve block and fascia iliaca compartment block will be the comparators.

Outcomes
Primary outcome [1] 321438 0
Change in pain score using the visual analogue scale (VAS) or pain assessment in advanced dementia (PAINAD) pain scale.
Timepoint [1] 321438 0
Pain scores will be documented prior to regional anaesthesia and for 12 hours after regional anaesthesia. Pain scores will be documented at 15, 30 and 60 minutes, then hourly.
Secondary outcome [1] 374943 0
Time of onset to analgesia.
Defined as the time of the first time at which a pain score (VAS or PAINAD) is recorded that is 1.5/10 less than the pain score prior to the block. As described in the study protocol
Timepoint [1] 374943 0
As described in the study protocol, pain scores will be measured at 15, 30, 60 minutes and then hourly for a total of 12 hours, or until the patient is checked in to the operating theatre, whichever is sooner.
Secondary outcome [2] 374944 0
Subjective observed patient comfort during nursing cares:
Nursing staff caring for patients will be asked to score the patient’s analgesia as adequate or inadequate during standard nursing cares that require movement. These may include:
Transfer to or from a bed
Transfer on and off a bedpan
Change of bedding or pad
Other painful patient movements at the discretion of the nursing staff.


This a composite secondary outcome. It will be documented on a single record sheet for each patient.
Timepoint [2] 374944 0
May or may not occur at any time within the data collection period. The data collection period is for 12 hours after the delivery of nerve block or until the patient is checked into the operating theatre, whichever is sooner.
Secondary outcome [3] 374945 0
Patient preference where cross over occurs and the patient receives a second form of regional anaesthesia in the pre-operative period.

Patients in whom cross over occurs will be identified by the acute pain service. The investigators, or the acute pain service on our behalf, will document which of the two blocks the patient found to be most effective at providing analgesia. This will be in the form of direct questioning by the investigators or the acute pain service on our behalf.

Other data including pain scores and opioid intake will be analysed if available.
Timepoint [3] 374945 0
Any time prior to arriving at operating theatre for surgical repair.
Secondary outcome [4] 374946 0
Block failure. As described in the protocol this is defined as not achieving a reduction in pain score (VAS or PAINAD) of 1.5 at any point in the data collection period. The data collection period is for 12 hours after the delivery of nerve block or until the patient is checked into the operating theatre, whichever is sooner.
Timepoint [4] 374946 0
As described in the protocol this is defined as not achieving a reduction in pain score (VAS or PAINAD) of 1.5 at any point in the data collection period. he data collection period is for 12 hours after the delivery of nerve block or until the patient is checked into the operating theatre, whichever is sooner.
Secondary outcome [5] 374947 0
Opioid Requirement. Measured by the electronic medical record and converted to oral mg of morphine using the faculty of pain medicine opioid calculator..
Timepoint [5] 374947 0
Opioid intake will be measured by analysis of the electronic medication chart from the insertion of block until 12 hours have passed, or the patient is checked in to the operating theatre, whichever occurs first.
This information will be converted to milligrams of oral morphine using the Faculty of Pain Medicine Opioid Calculator
Secondary outcome [6] 374952 0
Duration of analgesia. End of block effect is defined in the study protocol as an increase in pain score to < 1.0 from pre-block pain score in a patient who had a reduction in pain score of > 1.5 at any time.
Timepoint [6] 374952 0
Assessment is as described in the protocol and above. At 15, 30, 60 minutes after block and hourly thereafter for up to 12 hours or until the patient is checked in the operating theatre.

Statistical methods / analysis
Primary Outcome:
Reduction in pain scores over the first 12 hours after nerve block. We will apply the following statistical tests:
Students t-test to compare the reduction in pain score of patients who receive a PENGB compared to FNB and FICB
Subgroup analyses of the cognitively impaired and non-cognitively impaired population. These populations will have pain scored by the PAINAD and VAS respectively.
Subgroup analysis of FNB and FICB separately

Secondary Outcomes

Onset of block. Defined as the time until the first pain score > 1.5 less than the pre-block pain score.
T-test

Subjective observed patient comfort during nursing cares
Chai Square test

Patient Preference in the event of crossover
Chai Square test

Rates of block failure. Defined as not achieving a reduction in pain score of > 1.5 / 10
Chai square test

Duration of analgesia. End of block effect defined as an increase in pain on movement score to < 1.0 from pre-block pain score for that patient, in a patient who had a reduction in pain score on movement > 1.5 at any time.
T-test

Summary
Brief summary
The purpose of the study is to compare the effectiveness of three different techniques for regional anaesthesia (nerve blocks) that are currently used by doctors in the Emergency Department at Lismore Base Hospital. The study is primarily interested in confirming the effectiveness of the pericapsular nerve group block (PENG block) which has recently entered clinical practice. It has a sound scientific basis and anecdotally it appears to be a very effective block, but there is not yet published evidence comparing it's effect to that of the other nerve blocks in use: the femoral nerve block and fascia iliaca compartment block.
