Study information

Scientific title

Adults undergoing major lung surgery randomised to nutritional intervention or equivalent volume in water to assess the effects on post-operative outcomes



Study hypothesis

The aim of this study is to assess the feasibility of carrying out a randomised controlled trial comparing the effectiveness of a nutritional intervention (NI) of preoperative carbohydrate-loading drinks and early postoperative nutritional supplement drinks compared to receiving an equivalent volume of water in enhancing recovery after major lung surgery (MLS)

Ethics approval

Specialty: Cancer, Primary sub-specialty: Lung Cancer; UKCRC code/ Disease: Cancer/ Malignant neoplasms of respiratory and intrathoracic organs


After written informed consent, the patient will be randomised, before surgery, to either a nutritional intervention or water. Participants will be individually randomised into the study in an equal 1:1 ratio. Randomisation will be by a web based randomisation system. Patients will be stratified by diagnosis (cancer or benign) and type of surgery (key hole or open).

The nutritional intervention in brief the evening before surgery 4x200mls, the morning of surgery, 2X200mls of carbohydrate-loading supplement will be given. In the postoperative period patients will be given 125ml polymeric nutritional supplement drink twice a day from the period immediately after their operation for 2 weeks. The control group will consume the same quantity of water thus any benefit from the intervention will not be due to preventing dehydration.

Follow up will be 3 months post-surgery with Visual Analogue Score (VAS), Quality of Recovery and EQ5D questionnaires.

Primary outcome measure

Recruitment rate is recorded as the number of eligible participant who consent to participate in the study by 12 months.

Secondary outcome measures

1. Reasons for failure to recruit are assessed by screening log at the end of the study
2. Ease and efficiency of randomisation process is assessed by speed in which patients can be randomised and whether important prognostic data can be collected pre-operatively at the end of the study
3. Compliance rate of the intervention and contamination rate of the control group is assessed by data gathered by questionnaire and interview, we would expect to have a compliance of 50% of prescribed carbohydrate drinks and ONS taken as scheduled by the end of recruitment
4. Robustness of data collection processes during patient’s hospital stay is assessed by completeness of important peri-operative data to be over 90% for each patient.
5. Follow-up rate of patients at 3 months is assessed by a response rate of 80% at 3 months
6. Reasons for loss of follow-up (if any) are measured at 3 months,100% of mortality data will be captured.
7. Questionnaire best reflects patient experience is assessed by patient interviews at 3-4 week post-surgery.
8. Variability and distribution of quality of life questionnaires measured by return rate up to 3 months after surgery

Results and Publications

Publication and dissemination plan

This feasibility study is designed to identify if a substantive trial is possible. Although a definitive answer to the key research question on effectiveness of nutritional intervention in patient undergoing major thoracic surgery cannot be provided, the findings of this feasibility study will be of scientific interest to others in their own right. The dissemination strategy has been planned in three aspects. The first will ensure that patients and health professionals are informed of the feasibility findings; the second will engage multi-disciplinary professionals to support a proposal of a definitive RCT and the third will be to submit a grant application dependant on the success of the feasibility study (2018).

IPD Sharing plan:
The datasets generated and/or analysed during the current study during this study will be included in the subsequent results publication.
