title: Management of hyperthyroidism in Trinidad and Tobago.
abstract: A questionnaire study of current practices regarding the investigation and treatment of hyperthyroidism was undertaken in Trinidad and Tobago between December 1999 and March 2000. The study evaluated the choice of laboratory tests requested and the therapeutic choices for a standard patient with hyperthyroidism. In addition, clinical scenarios based upon variations of the standard case (by altering age, gender, goitre size and duration of disease) were also tested. Two hundred and ninety-six questionnaires were sent; 134 (45%) were returned, of which four were excluded for incomplete data. Ninety five per cent of respondents requested biochemical confirmation but the range of tests varied widely. Thyroid scintigraphy was requested by 36% and thyroid ultrasound by 35%. Medical treatment (75%) with antithyroid drugs was the most popular choice for treatment of the standard patient. This did not change significantly if the patient was male. On the other hand, radioiodine (62%) was more popular in the treatment of chronic/relapsing hyperthyroidism (p < 0.005). In the elderly, medical management was still the most popular choice (57%) but the choice of radioiodine therapy was significantly increased compared with that in the standard patient (36% vs 19%) (p<0.005). In a young female with a large goitre and chronic disease, surgical intervention (61%) was the treatment of choice, especially among surgeons and general practitioners; radioiodine was chosen by 28% of respondents (mostly internists). There is need for clear guidelines in investigating thyroid disease but therapeutic choices are well informed and consistent with accepted practice elsewhere. In particular there is a fairly liberal attitude towards radioiodine use in hyperthyroidism.
