    abstract = "Aim: SWING was a prospective, observational study conducted in nine
European countries primarily to assess direct treatment costs when
switching from short-acting human insulins to rapid-acting insulin
analogues (H-A) or vice versa (A-H) in patients with type 2 diabetes.
Methods: Data were collected at a baseline visit (time of switch) and at
approximately 3, 6 and 12 months post-switch.
Results: In total, 2389 patients switched from H-A (n = 2203) or A-H (n
= 186); another 603 were enrolled but ineligible. Mean (SD) direct
diabetes-related costs (pro-rated to account for variable visit
schedules) were (sic)548.7 (865.8) 6 months prior to switch, (sic)625.6
(1474.9) at 0-6 months and (sic)568.6 (590.7) 6-12 months following
switch for H-A, and (sic)544.5 (421.0), (sic)481.0 (301.5) and
(sic)461.6 (335.0) for A-H, respectively. Mean (SD) HbA(1c) decreased
over 12 months by 1.08 (1.53)% units H-A and 1.17 (1.45)% units A-H. A
small decline in hypoglycaemia occurred over time, but there were no
clinically meaningful changes in mean PROs.
Conclusions: There were small changes in mean direct diabetes-related
costs (following adjustment for time interval) in patients switching in
either direction. Improvements in mean HbA(1c) and incidence of
hypoglycaemia cannot necessarily be attributed to therapeutic switch.
