Management of diabetes in French prisons: a cross-sectional study

To assess by a survey the management of prisoners with diabetes treated with insulin in French prisons.

A questionnaire was sent to the head of healthcare services for prisoners of every French prison. Information was obtained on prevalence of insulin-treated diabetes prisoners and diabetes care in prison. The number of episides of ketoacidosis and hypoglycaemia needing hospital admissions were evaluated during the past year.

Among the 163 questionnaires sent, 115 were returned, giving an overall response rate of 69%. At the time of the study the prison population was 38 175 people. One hundred and sixty-nine prisoners were treated by insulin (0.4%). Self-monitoring of blood glucose was available only for 94 (55.6%) insulin-treated prisoners. A total of 130 (76.9%) prisoners performed two insulin injections daily or less, 105 (62.1%) prisoners were not allowed to keep their insulin delivery systems with them. Of the prisoners who treated themselves, 14 (12.1%) used syringes and 42 (36.5%) used pen devices. Ninety-two (55.1%) prisoners had had access to a diabetes specialist during the previous year. Diabetic diets were available in only 65 (60.7%) prisons. From June 1998 to June 1999, there were 20 hospital admissions for a diabetic ketoacidosis and 14 for hypoglycaemia.

This study shows that prison decreases the autonomy of diabetic prisoners who often cannot self-inject or test their blood. Access to visiting consultant diabetologists and specialist nurses to educate both prisoners with diabetes and prison staff could improve diabetic care.
