Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Anaesthetist performed limited transthoracic echocardiography (TTE) on prior to surgery.
a)approximate duration 20 minutes (including report)
b)on the same day of surgery
Intervention code [1] 258004 0
Diagnosis / Prognosis
Comparator / control treatment
Controls will get standard clinical assessment of cardiovascular function by the anaesthetist without TTE.
This is a routine assessment done by all anaesthetists on every patient prior to their anaesthesia (for all types of procedures including fractured neck of femur surgery). This assessment is not defined as every anaesthetist has their own method which is tailored to each individual patient (which depends on the patients health and the planned procedure). Subjects from both groups receive a standard cardiovascular examination by the anaesthetist but the TTE group receive a TTE and the control group do not. The TTE provides more accurate diagnostic information on the cardiovascular health of the patient.
Control group
Active

Outcomes
Primary outcome [1] 262097 0
Postoperative quality of recovery score (PQRS) 20% greater in the TTE group compared with controls.
Timepoint [1] 262097 0
3 days after surgery.
Secondary outcome [1] 273150 0
mortality
Timepoint [1] 273150 0
3 months after surgery.

Eligibility
Key inclusion criteria
-scheduled for isolated fractured neck of femur surgery (i.e. no additional surgical operations)
-informed consent from the patient
-able to complete the PQRS testing (requires sufficient English Language and cognitive skills).
Minimum age
66 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
no consent
Documented:
-TTE, stress TTE, cardiac MRI, TOE or documented cardiology consultation within the past 6 months,
-additional surgical procedures to be performed at the same time as the neck of femur,
-if the responsible anaesthetist insists on a TTE prior to surgery.
-Coronary perfusion imaging and coronary or left ventricular angiography do not necessitate exclusion from enrolment.

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients entered onto the emergency surgery list will be screened by research nurses. Suitable subjects will be confirmed with one of the primary investigators. Randomisation will be by opaque sealed envelopes produced by a non-study participant
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be by opaque sealed envelopes produced by a non-study participant, and the randomisation sequence will be generated using a computer random sequence generator. The randomisation code will only be issued prior to the commencement of surgery and will be known only to the treating anaesthetist.
Masking / blinding

Summary
Brief summary
This study aims to investigate the impact of anaesthetist-performed transthoracic echocardiography (TTE) on the quality of recovery of patients undergoing fractured neck of femur surgery.
It also aims to collect data to determine if a future trail investigating whether or not TTE reduces patient mortality after surgery.
