Multicenter Study Comparative Study
Using the 6-minute walk test to predict disability-free survival after major surgery.
The 6-min walk test (6MWT) is a common means of functional assessment. Its relationship to disability-free survival (DFS) is uncertain. ⋯ Of the risk assessment tools analysed, the DASI was the most predictive of DFS. The 6MWT was safe and comparable with cardiopulmonary exercise testing for all predictive assessments. Future research should aim to determine the optimal 6MWT distance thresholds for risk prediction.

Multicenter Study Clinical Trial
Delirium detection using relative delta power based on 1-minute single-channel EEG: a multicentre study.
Delirium is frequently unrecognised. EEG shows slower frequencies (i.e. below 4 Hz) during delirium, which might be useful in improving delirium recognition. We studied the discriminative performance of a brief single-channel EEG recording for delirium detection in an independent cohort of patients. ⋯ NCT02404181.

Randomized Controlled Trial Multicenter Study
Patient coping and expectations predict recovery after major orthopaedic trauma.
Persistent post-surgical pain and associated disability are common after a traumatic fracture repair. Preliminary evidence suggests that patients' beliefs and perceptions may influence their prognosis. ⋯ NCT00788398.

Observational Study
High-flow humidified nasal preoxygenation in pregnant women: a prospective observational study.
Obstetric airway guidelines recommend preoxygenation in preparation for general anaesthesia to achieve end-tidal oxygen concentrations (etO2) of ≥90%, and mention the potential use of high-flow humidified nasal oxygen (HFNO). We investigated the new HFNO technique (Optiflow™) in term pregnant women. ⋯ ACTRN 12616000531415p.

Observational Study
Development and evaluation of an obstetric quality-of-recovery score (ObsQoR-11) after elective Caesarean delivery.
Whilst validated quality-of-recovery (QoR) tools exist for general surgery, there is no specific obstetric equivalent. We aimed to develop and evaluate a modified QoR score after elective Caesarean delivery. ⋯ The ObsQoR-11 provides a valid, reliable, and responsive global assessment of recovery after elective Caesarean delivery.
