Quality of minor surgery carried out in primary or secondary care: population based randomised controlled equivalence trial
ISRCTN ISRCTN51268626
ClinicalTrials.gov identifier
Public title Quality of minor surgery carried out in primary or secondary care: population based randomised controlled equivalence trial
Scientific title A prospective randomised comparison of minor surgery in primary and secondary care
Acronym MiSTIC (Minor Surgery Trial In the Community)
Serial number at source HTA 95/25/03
Study hypothesis Increasingly with the move towards a "primary care led NHS" services previously provided within hospitals are being provided within primary care settings. One such service is minor surgery. Although minor surgery is widely practised in primary care it has not been subjected to critical analysis in a randomised study in terms of its safety, quality and cost effectiveness. This study is a prospective, randomised controlled trial comparing the treatment of minor surgical conditions in primary and secondary care in terms of these variables.
