Brief summary

Poor adherence to insulin regimens is reported in up to two-third of patients with diabetes; thus it is important to identify patients at risk and to develop strategies and tools to increase adherence to prescribed insulin regimens. This study will evaluate the efficacy of Insulclock® - small electronic device to help track date, time and dosage of the last injection, type of insulin used and temperature, with an alarm system to prevent insulin omissions and mistiming.

Detailed description

Diabetes is arguably the most urgent healthcare challenge of the 21st century. Poor adherence to insulin regimens is reported in up to two-third of patients with diabetes; thus it is important to identify patients at risk and to develop strategies and tools to increase adherence to prescribed insulin regimens. This study will evaluate the efficacy of Insulclock® - small electronic device to help track date, time and dosage of the last injection, type of insulin used and temperature, with an alarm system to prevent insulin omissions and mistiming. The Insulclock's real time memory and alert system are likely to improve treatment adherence, patient's satisfaction, and quality of life measures, which may improve glycemic control in insulin treated patients with Type 2 Diabetes.

Interventions

DEVICEInsulclock with feedback

Daily information on a smartphone on insulin administration (time and dosing) as well as reminders in the event of missing doses.

MeasureTime frameDescription
Number of Insulin Injection Irregularities.Week 0 through week 24.Number of insulin injection irregularities (omission, mistiming and dosing) will be registered on the Insulclock device, and data will be retrieved during each clinic visit to monitor treatment adherence.

Secondary

MeasureTime frameDescription
Change in Mean HbA1c.Baseline, 24 weeksHbA1c is a form of hemoglobin that is measured primarily to identify the three-month average plasma glucose concentration. The test is limited to a three-month average because the lifespan of a red blood cell is four months (120 days). Change in mean HbA1cas will be measure and recorded to monitor glycemic control.
Number of Episodes of Hypoglycemia.Week 0 through week 24.Number of episodes of hypoglycemia will be recorded. For this study, symptomatic hypoglycemia is defined as an event with typical symptoms (i.e., sweating, palpitation, and feeling of hunger) with or without confirmation by plasma glucose \<54 mg/dl (3.9 mmol/L).
Number of Episodes of Severe Hypoglycemia.Week 0 through week 24.Number of episodes of severe hypoglycemia will be recorded.Severe hypoglycemia is defined as episodes necessitating assistance and associated with measured plasma glucose \< 40 mg/dl (2.2 mmol/L), or with prompt recovery after administration of carbohydrates, glucagon, or other resuscitative actions.
Change in Diabetes Treatment Satisfaction Questionnaire (DTSQc-change) Score.Baseline, 24 weeksThe amplitude of the score on the DTSQc gives the degree of change in satisfaction while the direction (positive or negative) will provide guidance on the preference of one device over the other. DTSQc contains eight items scored on 7-point scales; scores range from +3 = much more satisfied now to -3 = much less satisfied now, with 0 (midpoint), representing no change.
Change in 7-point Self Monitoring of Blood Glucose (SMBG) Profile.3 to 5 days prior to randomization, up to 24 weeks.SMBG refers to home blood glucose testing for people with diabetes. 7-point SMBG profile include fasting, before meals, 2 hours after meals, and bedtime.
Change in Diabetes Quality of Life Clinical Trial Questionnaire-Revised (DQLCTQ-R) ScoreBaseline, 24 weeks.The DQLCTQ-R is a 57-item scale that comprises 8 dimensions: physical function, energy/fatigue, health distress, mental health, satisfaction, treatment satisfaction, treatment flexibility, and frequency of symptoms.
Change in Daily Fasting Glucose Profile Averages.Week 0 through week 24.Daily fasting glucose profile averages will be recorded to monitor glycemic control.
Change in Diabetes Related Quality of Life (DRQoL) Scores.Baseline, 24 weeksDRQoL is a composite score, consisting of a standardized and unweighted Insulin Treatment Experience Questionnaire Score (ITEQ), and Problem Areas in Diabetes (PAID) questionnaire score. ITEQ includes 7 domains: leisure activities (4 items), psychological barriers (2 items), handling (5 items), diabetes control (6 items), dependence (5 items), weight control (3 items), sleep (2 items); + 1 additional item assigned to assess overall satisfaction with current insulin therapy regimen. The PAID contains 20 items that describe negative emotions related to diabetes commonly experienced by patients with diabetes. Each question has five possible answers with a value from 0 to 4, with 0 representing no problem and 4 a serious problem. The scores are added up and multiplied by 1.25, generating a total score between 0 - 100.

Pre-assignment details

The study consented 121 participants. The study team realized that changes needed to be done for the protocol to be efficient. The first 28 candidates were consented for pilot data, ten of them were screen failures, 18 were randomized. Data on Insulclock device malfunctions were collected, it was planned to improve all issues by the time the main phase of the study started. 93 subjects were consented for the main study, 13 were screen failures, and 80 subjects were randomized.
