Description of intervention(s) / exposure
Brief name: Comparison of effect of standard information vs. standard information plus nocebo explanation on side effect reporting after intravenous iron infusion.
Participants (patients receiving IV iron infusion at Auckland City Hospital) who are randomised into the intervention group will receive a standard consultation for IV iron infusion (including side effect information) plus an explanation of nocebo effect. The nocebo explanation will outline the relationship between bodily sensations and individuals‘ attributions, expectations, and beliefs, and will offer an explanation of the nocebo phenomenon.
The intervention consultation will be delivered by a Consultant Anaesthetist according to a standardised script.
The mode of delivery will be face to face and executed individually to each patient.
The intervention will be delivered once per patient over approximately a 10 minute period
The intervention will be delivered at the Post Anaesthetic Care Unit on Level 8 of Auckland City Hospital (Auckland, New Zealand).
After the intervention has been delivered participants will be asked to complete a post infusion symptom questionnaire. Participants will also be contacted via telephone 3 days after their infusion to complete the same symptom questionnaire.

Summary
Brief summary
In patients with a low haemoglobin (Hb) for whom oral iron is considered unsuitable/has been unsuccessful, intravenous (IV) iron is used. Indications for IV iron infusion include malabsorption, continuing blood loss, poor adherence, or intolerance. Iron infusions are also sometimes offered in a preoperative setting to patients with iron deficiency anaemia. At Auckland City Hospital, IV iron is administered as a single dose infusion taking approximately 15minutes. Immunological hypersensitivity reactions to IV iron are rare, however unwanted side effects (e.g. flushing, joint/muscle pains, headache and dizziness) are commonly reported by patients (Rampton et al., 2014). In a healthcare context, the nocebo effect can be defined as the experience of symptoms, that are induced by the patient’s own negative expectations and/or by negative suggestions from clinical staff (Hauser, Hansen, & Enck, 2012). In a recent study we found that an explanation of the nocebo effect as a symptomatic experience influenced by negative expectations was effective in significantly reducing symptom reporting (Crichton & Petrie, 2015). In this study we are investigating whether the nocebo effect has relevance to clinical medicine by examining whether changing standard verbal preparation information to include an explanation of the nocebo effect can reduce side effect reporting after IV iron infusion. Reductions in side effect reporting may have considerable clinical benefits in terms of reducing non-compliance with medications, and reduction of illness burden and distress. Design: Potential participants will be sent study information with their appointment letter. On the day of their appointment they will be provided with verbal + written information on the project, and invited to participate by the research assistant. Once written informed consent has been obtained, a baseline questionnaire (including symptom data) will be completed. Participants will be randomised into one of 2 groups; either a) control: standardized preparation for IV iron infusion including side effect information, or b) intervention: standardized preparation for IV iron including side effect information plus explanation of nocebo effect. The control and intervention conditions will be delivered by a consultant anaesthetist (according to a standardised script for each condition). The nocebo intervention will outline the relationship between bodily sensations and individuals‘ attributions, expectations, and beliefs, and will offer an explanation of the nocebo phenomenon. The research assistant (who will be blind to condition) will collect participant symptom data following IV iron infusion and at day 3 post-infusion.
