Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Drainage of the pleural fluid through an intercostal catheter inserted into the pleural space. This procedure will be performed by the treating intenisive care clinician who has been trained in this procedure. This procedure is considered a routine core skill for intensive care training. Ultrasound guidance will be used for insertion (this can be real-time or “x marks the spot” but the latter only with the patient in the exact position that drainage will occur and with marking occurring within 15 minutes of skin puncture). The choice of drain size and drainage technique (blunt, modified Seldinger, or thoracentesis) will be left to the discretion of the treating clinician. Complete evacuation of the fluid will be attempted and if that requires insertion of a second drainage tube that will be allowed as required as per normal practice. This treatment is externally obvious to all caring for the patient and therefore treatment allocation cannot be concealed/blinded. The procedure takes 20 to 40 minutes on average.

Outcomes
Primary outcome [1] 305591 0
Number of Pleural Effusion Related Serious Adverse Events (PERSAE’s)
These are determined through clinical assessment and documentation in the medical record. PERSAE’s will include all serious adverse events that may reasonably be considered to be related to the pleural effusion management strategy. All potential adverse events where there is lack of consensus between the treating clinician and the study investigators will be referred to an independent expert for the final decision.
PERSAE’s may occur in either treatment arm, must be related to pleural effusion management and include: a) Pneumothorax: Defined as unexpected new presence of pleural air on chest radiograph. - Non-air leak pneumothorax (e.g. trapped lung/ex vacuo pneumothorax) that does not cause clinically apparent deterioration or any change in treatment will not be considered a serious adverse event
b) Bronchopleural Fistula: Defined by >24 hours of ongoing air leak evidenced by ongoing bubbling with each breath or increase in pneumothorax size in the event of chest drain occlusion >24 hours after diagnosis of pneumothorax
c) Dislodgement: Inadvertent removal of chest drain
d) Failure of Insertion: Inability to insert planned chest drain requiring abandonment of procedure after skin incision or needle insertion, resulting in a SAE
e) Bleeding which occurs as a result of pleural effusion management and requires action above and beyond applying pressure to the site
f) Hypotension requiring treatment with new or increased vasopressor and/or i.v. fluid. Either i) at the time of pleural effusion drainage or ii) as a result of inadequate management of the cause of the pleural effusion (e.g. sepsis, untreated bleeding)
g) Organ Puncture as a result of pleural procedure
h) Respiratory Failure: Worsening or new respiratory failure requiring escalation in oxygen delivery device or ventilation strategy
i) Missed diagnosis: Missing a diagnosis that may have resulted in a SAE j) Any other SAE that may reasonably be attributable to either pleural management strategy SAE will be defined as any events (Pleural effusion related, or not) that cause death or irreversible harm, or require treatment(s) to prevent these outcomes.

Delayed drainage procedures undertaken in the control arm solely to manage effusion increase or ongoing ventilation requirement do not constitute PERSAE. However, if a delayed drainage procedure (>48 hours after randomisation) reveals an undiagnosed or untreated, life-threatening or serious condition, then that would constitute a PERSAE. All SAEs will be reported to the data and safety monitoring committee within 48 hours of detection.

Primary outcome [2] 323292 0
P:F ratio at 48 hours after randomisation.
P:F ratio is the ratio of the arterial PaO2/fraction of inspired O2 and is a measure of oxygenation adjusted for the amount of oxygen the patients is breathing. The PaO2 (partial pressure of arterial oxygen) is determined form routine analysis of arterial blood, usually in the intensive care from an arterial catheter. Only those patients that require an arterial blood gas as part of their usual care will have arterial blood samples and these will be taken 6 hourly for the first 72 hours if required as per usual care. The FiO2 is simply the amount of oxygen provided and is routinely recorded at least hourly on the nursing observation charts.

Statistical methods / analysis
The final sample size will be 52 patients (26 per group) randomised to drainage or expectant management in a 1:1 ratio.
Based on the previous observational study the pooled mean P:F ratio at baseline was 252.3 (SD=106.0; SEM=7.4)1314. The drainage group (DG) improved after 48 hours by mean 77.7 mmHg and the expectant management group (EMG) by -7.7 mmHg. This implies expected means in the proposed study at 48 hours after treatment of 330.0 (DG) and 244.6 (EM). The sample size that will give 80% power to statistically detect this difference in P:F ratio at 48 hours with an a (type one error rate) value of 0.05 is calculated to be 48 (24 in each group). Allowing for a 10% crossover/loss to follow up rate the required sample size to ensure power to detect a difference in P:F ratio in the per protocol analysis is 52 patients.
