Staff at Guy's and St Thomas' have in just three days gathered 26 bags of clothing to be shipped to Port-au-Prince by the Haiti Hospital Appeal.
The Guy's and St Thomas' NHS Foundation Trust was contacted last Monday by the appeal, and by Wednesday there were piles of bags ready to be transported to Portsmouth and shipped to Port-au-Prince this week to help survivors of the earthquake that devastated the country four weeks ago.
The efforts were coordinated by Professor Lucilla Poston, head of reproduction and endocrinology and Marie McDonald, clinical director of women's health.
Marie said: "I've been overwhelmed by the compassion of our staff. They've responded in the most generous and speedy fashion; we're very proud."
The Haiti Hospital Appeal was established in 2006 to provide life saving care to some of the most desperate and at risk people in Haiti; one of the poorest countries in the western hemisphere.
It was initially set-up to provide maternity and paediatric care in the north of the country, and has since founded a health centre, an ambulance service, a children's home, and a hospital building project.
Phil Johnson, treasurer of the appeal, said: "We can't thank Guy's and St Thomas' enough for the incredible quantity of vital supplies staff have donated. The situation was desperate before the earthquake, but conditions on the ground have become alarmingly poor since.
"The carload of bags have all been sorted into categories and are now on their way to help those in need and we are so grateful to all those who helped."
