Routine Use of Sensor-Augmented Pump Therapy - a Follow up Study
Routine Use of Sensor-Augmented Pump Therapy - a Follow up Study
The aim of this study is to document the routine practice in continuous glucose monitoring
 (CGM) in patients treated with sensor-augmented pump therapy and to assess clinical outcome
 (HbA1c) before the start of the sensor use to the end of the follow-up period. Moreover, data
 on treatment satisfaction, and fear of hypoglycemia, cost of the therapy, side effects and
 treatment interruption will be collected.
The most advanced technologies for the treatment of type 1 diabetes mellitus (T1DM) include
 insulin pumps for continuous subcutaneous insulin infusion (CSII) and glucose sensors
 allowing continuous glucose monitoring(CGM). Randomized controlled trials have shown that
 access to CGM can improve control in poorly-controlled patients regardless of insulin
 treatment therapy via reduced hyper- and hypoglycaemic excursions and improved mean HbA1c
 value.

 The Medtronic personal CGM device is composed of a glucose sensor linked to a MiniLink
 REAL-Time Transmitter, which transmits data from the glucose sensor to the insulin pump. The
 integration of these two technologies (CSII and personal CGM) into one system is called
 sensor-augmented pump therapy (SAP).The devices are CE-marked and routinely used in clinical
 practice in the Swedish market.

 Based on the clinical evidences provided, the Swedish Dental and Pharmaceutical Benefits
 Agency (TLV) concluded that the personal CGM when used in combination to a Medtronic insulin
 pump as SAP should be included in the Swedish reimbursement system. However the decision was
 upon specific patient indications:

 Patients with two or more severe hypoglycemias/year that require help from another person or
 Patients with HbA1c of at least 9%, in cases where optimized insulin therapy has not been
 effective or Children taking at least 10 medically required plasma glucose tests
 (fingersticks) per 24 hours and that certain follow-up information has to be complemented and
 submitted to TLV before March 1st, 2012.

 TLV requires follow-up information on T1 diabetes patients using SAP in Swedish clinical
 practice and based on the following outcome parameters:

 HbA1c-level of the patients Quality of life with use of CGM Side effects and therapy
 interruptions. Use and costs of the therapy Frequency of hypoglycemia Therefore, this project
 will observe the routine practice of personal CGM utilization in combination to Medtronic
 insulin pumps in T1DM patients in Sweden in approximately 15 investigational centers.

 The aim of this project is to reflect the daily practice in personal CGM therapy (sensor and
 MiniLink REAL-Time Transmitter) usage in diabetes patients treated with Medtronic insulin
 pumps in Sweden. Data on the HbA1c value before and up to six months use of personal CGM will
 be collected and information on the outcomes requested by TLV will be included in the study.
 The patient reported outcomes will be supplemented with patient preference data and will be
 estimated with a willingness-to-pay (WTP) approach.
