If as a result of injury/loss/pain/suffering, a negligence claim against your Hospital/Health Authority can be proved, then you should be entitled to compensation. And yes, this could be a lengthy process, not simply because any claim would probably be contested, but injuries and ongoing injury would need to be medically assessed over time and......probably the worst aspect..... endless delays could be experienced because all those involved would close ranks faster than if they all had magnets in their sleeves! Medical records, reports, results, etc., often 'go missing', staff involved might have left or be unavailable for interviews etc., etc., You would need to be in it for the long run and find the best legal support possible. Big Girl Pants would have to be worn by you, along with a realistic and patient but determined state of mind !
If, on the other hand, in using the words ' justice and honesty', you're not wanting financial compensation but somebody to admit to wrongdoing, a mistake, negligent handling or a poor outcome of your procedure so that methods might be changed for the good of patients in future, I think it would be a surprise if anyone investigated sufficiently to make you feel less aggrieved once a probably very brief exchange of correspondence had taken place. And in either case, liability would be highly unlikely to be admitted by the Hospital insurers, even if they agreed to compensate you, so you wouldn't have that small satisfaction either.
What is VERY important and what you should do initially is avoid like the plague any dealings with legal companies set up to just do 'no win, no fee' claims. It would be unlikely that your potential claim would initially be assessed by an actual Solicitor. Their client throughput, a bit like insurance companies, is normally enough to keep numbers of young and unqualified clerks dealing with 'phone enquiries, completing standard claim forms over the 'phone and, more often than not, being unable to advise on your many concerns as to the realistic outcome, or otherwise, of your claim.
The best you can do to start, in the event of your wanting to pursue this further, is to look for a firm of Solicitors which has a department dealing with personal injury, medical negligence etc., Contact them - often possible via a contact page on their website - and say that you would like an appointment to see or speak to one of their named P.I specialists in the firm. What usually happens then is that you may be offered a half hour appointment, without charge. Sufficient time to at least briefly discuss the detail of your current problem and get answers to some of your questions, but do make sure you have dates and times and names to hand, and any medical information that might be helpful. Once the lawyer has had sight of this, and spoken to you about what happened, if he or she suggests a claim may be possible they will also suggest to you how this could be funded. If you are told that the claim does not seem viable or that your time and energy will be wasted in trying to pursue something with very little chance of success, then that's the time when you can possibly decide where you wish to go from there. Litigation is not for the faint-hearted so you would need an honest opinion from someone well used to dealing with medical negligence claims to help you make any decisions.
Whatever has gone wrong for you, I do hope that you are beginning to feel better and, if you have been distressed and angered by what has happened, that with professional advice you will be able to resolve those difficulties satisfactorily and put a bad experience behind you. Good luck !
