A recent study suggests that more work is required to assist people over 65 to make complaints about poor health care. It appears that some people are  prevented from complaining because they don't know how to make a complaint, or the complaints process isn't accessible, whilst others are prevented from complaining because of concerns that it might affect their treatment in future. 

As is made clear in the article, having an effective complaints system in the NHS is important to prevent future incidents and to enable services to identify where improvements are required. It is to be hoped that further progress can be made in improving the complaints service, particularly given the UK's ageing population.
