Perspectives of patients with type 1 or insulin-treated type 2 diabetes on self-monitoring of blood glucose: a qualitative study

<p>Abstract</p> <p>Background</p> <p>Self-monitoring of blood glucose (SMBG), including self-regulation, is an important tool to achieve good glycemic control. However, many patients measure their glucose concentrations less often than is recommended. This study investigates patients' perspectives of SMBG and all relevant aspects influencing SMBG in patients with type 1 and insulin-treated type 2 diabetes.</p> <p>Methods</p> <p>In depth interviews were conducted with 13 patients with type 1 diabetes from an outpatient clinic and 15 patients with type 2 diabetes from general practices. All interviews were transcribed verbatim and analyzed using the Grounded Theory approach.</p> <p>Results</p> <p>A wide variety of SMBG was encountered. Perceptions, goals of SMBG and personal and contextual factors were identified, influencing the respondents' perspective of SMBG, and leading to this variety. Respondents experienced a discrepancy between their own and the professionals' perceptions and goals. Respondents' perception of SMBG ranged along a continuum from 'friend' to 'foe'. With respect to the goals, the respondents experienced tension between achieving good glycemic control and quality of life, and deliberately made their own choices. The performance of SMBG was tailored to their perceptions and personal goals. Personal and contextual factors such as hypo- or hyper (un)awareness, knowledge, and contact with professionals acted as either facilitating factors or as barriers to SMBG, depending on the respondents' perspective. A SMBG model was developed providing a representation of the factors and their interrelations.</p> <p>Respondents with type 1 diabetes seemed more resigned to their situation and SMBG was more integrated into their lives.</p> <p>Conclusions</p> <p>From the patients' perspective, professionals positively present SMBG as a 'friend' in order to achieve strict glycemic control. Whereas patients can also perceive SMBG as a 'foe'. They primarily seek a personal balance between achieving glycemic control and quality of life, leading them to deliberately make other choices regarding SMBG performance than was recommended. Gaining insight and discussing all factors affecting SMBG will help professionals and patients come to mutually agreed goals and to tailor the performance of SMBG to the individual patient. This should result in a more optimal use of SMBG, an improved quality of life, and improved clinical parameters.</p

Effects of three frequencies of self-monitored blood glucose on HbA1c and quality of life in patients with type 2 diabetes with once daily insulin and stable control:A randomized trial

Objective: The optimal frequency of self-monitoring of blood glucose (SMBG) in patients with type 2 diabetes (T2DM) with stable glycemic control is unknown. This study investigated effects of 3 frequencies of SMBG on glycemic control and quality of life after 9 months in patients using one long-acting insulin injection a day. In an open-label, multi-center, primary-care, parallel (1:1:1) randomized trial in the Netherlands including patients with T2DM, HbA1c ≤ 58 mmol/mol (≤ 7.5%), stable glycemic control, treated with one insulin injection daily, three frequencies of 4-point glucose measurements (before meals and bedtime) were weekly (n = 22), every 2 weeks (n = 16) and monthly (n = 20) were compared. Results: A total of 58 patients with T2DM were included by 38 general practitioners, which was lower then anticipated. There were no significant between group differences in HbA1c (mmol/mol); group C compared to A and B; - 2.7 (95% CI - 6.4, 1.0) and - 1.0 (95% CI - 4.9, 3.0) and quality of life. Baring in mind the lower than anticipated inclusion rate, there were no significant differences in HbA1c and quality of life between three different frequencies of SMBG in patients with stable glycemic control using one long-acting insulin injection.</p

Self-Monitoring of Blood Glucose:Professional Advice and Daily Practice of Patients With Diabetes

Purpose This study investigated the advice given by diabetes educators in Europe, and the daily practice of Dutch patients with diabetes regarding the use of the first or second drop of blood and other aspects concerning self-monitoring of blood glucose (SMBG). Method During a diabetes conference in 2009, 96 European diabetes educators (including 46 Dutch educators) completed a single-item questionnaire about the use of the first or second drop of blood for glucose monitoring. A self-reported questionnaire with 20 questions about performing SMBG was filled out by 111 patients from an outpatient diabetes clinic of a Dutch hospital. Results Patients were advised to wash their hands with water and soap and use the first drop of blood by 89% of the Dutch and 72% of other European diabetes educators, while 58% of the patients reported to do this. When the patient cannot wash the hands, 85% of the Dutch and 52% of the other European educators advised to use the second drop of blood, while 26% of the patients reported always using the first drop without washing hands. Always using the side of the fingertip and using the lancet once, as advised in guidelines, was reported by only 41% and 55% of the patients, respectively. Conclusions There is no general agreement between professionals regarding the advice on aspects concerning SMBG. Patients also reported different acts in daily practice. Developing uniform international SMBG guidelines, education, and repeated evaluation of the process of collecting an accurate blood sample are needed

Cross-cultural adaptation of the diabetes management self-efficacy scale for patients with type 2 diabetes mellitus: Scale development

Background: As a profession, nurses are particularly concerned with cross-cultural influences that affect the health practices of populations. Although the international literature describes questionnaires and specific scales in health and disease behaviours, adequate Turkish-language instruments are scarce. Therefore, suitable Turkish-language instruments need to be developed or adapted for the Turkish population

Isolation and Characterization of Human Monoclonal Antibodies from Individuals Infected with West Nile Virus

Monoclonal antibodies (MAbs) neutralizing West Nile Virus (WNV) have been shown to protect against infection in animal models and have been identified as a correlate of protection in WNV vaccine studies. In the present study, antibody repertoires from three convalescent WNV-infected patients were cloned into an scFv phage library, and 138 human MAbs binding to WNV were identified. One hundred twenty-one MAbs specifically bound to the viral envelope (E) protein and four MAbs to the premembrane (prM) protein. Enzyme-linked immunosorbent assay-based competitive-binding assays with representative E protein-specific MAbs demonstrated that 24/51 (47%) bound to domain II while only 4/51 (8%) targeted domain III. In vitro neutralizing activity was demonstrated for 12 MAbs, and two of these, CR4374 and CR4353, protected mice from lethal WNV challenge at 50% protective doses of 12.9 and 357 μg/kg of body weight, respectively. Our data analyzing three infected individuals suggest that the human anti-WNV repertoire after natural infection is dominated by nonneutralizing or weakly neutralizing MAbs binding to domain II of the E protein, while domain III-binding MAbs able to potently neutralize WNV in vitro and in vivo are rare
