Clinical Measurement Services
Clinical Measurement Services consists of four departments at Cairns Hospital:
- Cardiac Investigations Unit
- Respiratory Laboratory
- Sleep disorders centre
- Neurodiagnostic Unit
All the units perform non-invasive physiological investigations on inpatients and outpatients.
Referrals (who can refer?)
Medical referrals using the referral/request form MR 51 and MR51A are accepted from medical officers within the hospital. GP’s and outside specialists can also refer for outpatient investigations.
The completed referral form must be either sent or taken to the department where the tests are to be conducted. The Thoracic Clinic will take bookings for the Respiratory Laboratory. Requests for sleep studies on patients’ from outpatient clinics will be forwarded on to the Thoracic Specialist. Provider numbers must be included on the request. Referrals for the Neurodiagnostic Unit can be faxed/sent directly to Neurology Department for processing and categorising by the Neurologist, where an appointment will be then scheduled accordingly.
Reasons for referral
Cardiac Investigations Unit: To assess cardiac conditions such as an MI or suspected MI, chest pain, cardiac abnormalities and irregular cardiac rhythm. Adult and neonatal assessment of congenital heart conditions.
Respiratory Laboratory: To investigate lung function in patients’ with breathing difficulties such as asthma, COPD, fibrosis or pulmonary disease. To perform breathing tests to establish a baseline prior to operations or some cancer treatments.
Sleep Disorders Centre: To investigate patients’ for sleep disorders such as sleep apnoea. To assess current treatment of sleep apnoea is sufficient, eg Continuous Positive Airway Pressure is adequate.
Neurodiagnostic Unit: To investigate suspected seizures or seizure disorders, nerve disorders, or neuromuscular conditions.
Cardiac Investigations Unit: This unit performs echocardiograms, exercise stress tests, Holter monitoring and other cardiac investigations including Transoesophageal echocardiograms and Dobutmine Stress echocardiograms
Respiratory Laboratory: Detailed lung function tests including spirometry, gas transfer tests and plethysmography to measure lung volumes. Bronchodilator tests, six minute walk tests, bronchoprovocation tests and High Altitude Simulation Tests are also conducted.
Sleep Disorders Centre: Overnight polysomnography is performed to assess whether patients’ have sleep apnoea or other sleep related disorders. Patients’ diagnosed with sleep apnoea are treated with Continuous Positive Airway pressure and reassess in the laboratory. A CPAP clinic is conducted during the day to issue eligible patients with a QH CPAP device or to troubleshoot any problems patients may have with their CPAP devices.
Neurodiagnostic Unit: This unit performs EEG’s, (routine, sleep deprived, and prolonged) on patients all ages from neonates to geriatrics, who may have suffered from a seizure, suspected seizures, or unexplained blackouts, and epileptic patients. Nerve conduction studies and electromyography studies are also conducted.
Inpatient and Outpatient services
All departments see both inpatients and outpatients and perform the range of investigations as listed above.
On Call services (what and how to access)
Cardiac Investigations: There is a medical doctor on call to perform urgent echocardiograms. Details of the doctor on call are available from the Coronary Care Unit or Switch.
