Patients lost to follow-up in acromegaly: results of the ACROSPECT study.

Objective: The complex management of acromegaly has transformed this disease into a chronic condition, with the risk of patients being lost to follow-up. The objective of this study was to estimate the proportion of acromegalic patients lost to follow-up in France and to determine the impact that abandoning follow-up has on the disease and its management.

Design: ACROSPECT was a French national, multicentre, cross-sectional, observational study.

Methods: Acromegalic patients were considered lost to follow-up if no new information had been entered in their hospital records during the previous 2 years. They were traced where possible, and data were collected by means of a recall visit or questionnaire.

Results: In the study population, 21% of the 2392 acromegalic patients initially followed in 25 tertiary endocrinology centres were lost to follow-up. At their last follow-up visit, 30% were uncontrolled, 33% were receiving medical therapy and 53% had residual tumour. Of the 362 traced, 62 had died and 77% were receiving follow-up elsewhere; the leading reason for abandoning follow-up was that they had not been informed that it was necessary. Our analysis of the questionnaires suggests that they were not receiving optimal follow-up.

Conclusions: This study underlines the need to better inform acromegalic patients of the need for long-term follow-up, the absence of which could be detrimental to patients' health, and to develop shared care for what must now be regarded as a chronic disease.
