Patient Satisfaction and Clinical Efficacy of Novel Blood Glucose Meters Featuring Color Range Indicators in Patients With Type 2 Diabetes: A Prospective Study

Abstract

Introduction Self-monitoring of blood glucose (SMBG) plays an important role in diabetes management. The Contour ® Next One glucometer is a recent glucometer that delivers blood glucose results by an immediate color indicator to aware users when blood glucose is at a critical high or low. The main purpose of the study was to assess the impact of an application of a blood glucose meter (BGM) having a color range indicator on clinical characteristics and glucose monitoring satisfaction (GMS) among patients having type 2 diabetes (T2D). Methods A total of 85 (male 42 and female 43) patients with T2D were switched to a BGM having smartLIGHT™ target range indicator (blood glucose meters featuring color range indicator) using Contour ® Next One glucometer. Demographic data, as well as glycemic control, were collected at baseline and 12 weeks. At the time of the baseline and 12 weeks of the study, a trained interviewer gave the GMS survey questionnaire to every patient in order to collect the glucose monitoring satisfaction. In addition to GMS, a patient's perceptions of smartLIGHT™ feature satisfaction survey responses were also collected from the patients at the end of the study (12 weeks). Results Compared to baseline, a significant improvement was observed in the subdomains of glucose monitoring satisfaction survey (GMSS) score on openness (p=0.0001), emotional burden (p=0.0001), behavioral burden (p=0.0001), and trust (p=0.0001) at the end of the study. Overall, the total GMS score at baseline was 2.61 ± 0.51, which improved up to 3.16 ± 0.63 (p=0.0001) during the period of 12 weeks. The patient satisfaction with smartLIGHT™ survey outcomes exposed evidence of satisfaction among the study population at the end of the study. There were statistically insignificant reductions observed in glycosylated hemoglobin (HbA1c) (p=0.063) and the frequency of hypoglycemia (p=0.057) at the end of the study. Conclusions The study demonstrates a significant improvement in the subdomains of GMSS-openness, emotional burden, behavioral burden, and trust-at 12 weeks than at the baseline, with the increased total GMSS score. Similarly, high satisfaction with the color-based smartLIGHT™ feature was also observed at the end of the study.

Glucometer Usability for 65+ Type 2 Diabetes Patients: Insights on Physical and Cognitive Issues

“…A recent randomized controlled study [26] found that the usage of BGMs with Colour Range Indicator (CRI) reduces glycated haemoglobin (HbA1C)-HbA1C is a gold standard blood test for patients with diabetes that measures the proportion of glycated haemoglobin which is in correlation with the blood glucose level over the past 3 months. Other studies proved that the use of CRI improves the management of diabetes [20,22,23,25].…”

“…By using a colour scale, patients can better interpret results, classify BG readings as low, high or in range, and make decisions accordingly [19]. The colour scale allows the definition of a glucose result as either "near low" or "near high" by glancing in the direction of below or above range segments, allowing patients to either take action before their score would become too high/too low or reflect on the reasons that generated "near low"/"near high" results [22,23]. The introduction of the colour system improves patients' feeling of being safe and in control because they are alerted when results are near high/low values [22,24,25].…”

Evaluation of Patient Satisfaction and Clinical Efficacy of Using Blood Glucose Meters Featuring Color-Coded Indicators in Patients With Type 1 Diabetes: An Observational Hospital-Based Study

“…At the time of the baseline visit and 12 weeks of the study, a trained interviewer introduced Glucose Monitoring Satisfaction Survey (GMSS) [14] to every patient to test glucose monitoring satisfaction. In addition, patient-reported satisfaction with the Medisafe Fit Smile color-coded features (MSCF) survey was collected at the final site visit [15].…”

“…Alternatively, the MSCF survey includes 12 questions to measure the participant's Medisafe Fit Smile perception. A trained interviewer asked the patients to rate their experience with the system on a scale ranging from one (strongly agree) to five (strongly disagree) [15].…”

User Performance Evaluation and System Accuracy Assessment of Four Blood Glucose Monitoring Systems With Color Coding of Measurement Results

“…As a result, not only metabolic parameters and glycemic control of patients with diabetes improve, but also their diabetes management performance and satisfaction. 13,[15][16][17] The aim of this study was a system accuracy assessment and a user performance evaluation of four BGMSs with color coding of BG results.…”
