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

BACKGROUND: 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. METHODS: 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. RESULTS: 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.Respondents with type 1 diabetes seemed more resigned to their situation and SMBG was more integrated into their lives. CONCLUSIONS: 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.

Reliability and validity of a fruit and vegetable self-efficacy instrument for secondary-school students in the Netherlands.

OBJECTIVE: To develop a 'fruit self-efficacy' (FSE) instrument and a 'vegetable self-efficacy' (VSE) instrument for secondary-school students in the Netherlands and to test the reliability and validity of these instruments. DESIGN: Methodological research. SETTING: Seven secondary schools in the Netherlands. SUBJECTS: Students (11-19 years of age) completed the two instruments in the classroom (n 466). Out of the original subject group, 106 students completed the instruments a second time. RESULTS: The relevance of the twenty-two items of the two developed instruments was evaluated on two occasions by four experts. This procedure resulted in seventeen items for both instruments. Further analysis was carried out on the basis of the secondary-school students' answers. Factor analysis identified two unidimensional instruments. Cronbach's α was 0·94 for the FSE instrument and 0·95 for the VSE instrument. The intra-class correlation coefficient between the test and the retest for both instruments varied between 0·33 and 0·84 (P < 0·05), depending on how the tests were taken (during class or on the student's own initiative), and the order in which the tests were completed (started or finished with a different instrument used for similar research). The correlation between FSE and fruit consumption was 0·41 (P < 0·01) and between VSE and vegetable consumption was 0·32 (P < 0·01). CONCLUSIONS: The two instruments are sufficiently reliable and valid to assess the FSE and VSE of secondary-school students in the Netherlands. Further research, in which the predominant ethnic minorities in the Netherlands are sufficiently represented, is required to confirm this conclusion.

The effects of music on physiological responses and sedation scores in sedated, mechanically ventilated patients.

AIMS AND OBJECTIVES: A pilot study designed as future randomised controlled trial was carried out to determine the effects of music on physiological responses and sedation scores in sedated, mechanically ventilated patients. BACKGROUND: Mechanically ventilated ICU patients, even when receiving intravenous sedatives, may experience stress and anxiety. One possible intervention to reduce stress and anxiety is listening to music. DESIGN: A randomised controlled trial design with repeated measures was used. METHODS: Data were collected over a six-month period in 2006. Twenty subjects were randomly assigned to either the experimental or control group. Subjects in the experimental group listened to music three times for 30 minutes over two days; subjects in the control group undertook three 30 minute rest periods. Physiological effects of music on systolic, diastolic and mean arterial blood pressure and heart and respiratory rate were assessed. Sedation scores were also measured. RESULTS: Physiological parameters did not show a significant difference between the groups. Patients in the experimental group showed significantly higher Ramsay (sedation) scores than patients in the control group after the first session. The higher scores indicate that patients were less responsive to external stimuli. CONCLUSION: Our results suggest that listening to music leads to higher sedation scores in sedated, mechanically ventilated ICU patients. No significant decreases in physiological parameters were observed. Listening to music showed no negative changes in the condition of these patients. Future research should focus on the use of other measures, such as stress hormones, to assess stress in sedated, mechanically ventilated ICU patients. RELEVANCE TO CLINICAL PRACTICE: For the sedated, mechanically ventilated ICU patient, the benefit of music may lie in the associated (deeper) level of sedation that is achieved, which in turn may make the patient less susceptible to stress and anxiety.

The role of self-efficacy in vascular risk factor management: a randomized controlled trial.

OBJECTIVE: Given the large number of patients at high risk of vascular events, new strategies are needed to reduce vascular risk. We investigated whether self-efficacy promotion could change self-efficacy levels in patients with vascular diseases and whether baseline self-efficacy and changes in self-efficacy were related to changes in vascular risk factors. METHODS: One hundred fifty-three recently referred patients with symptomatic vascular diseases (cerebrovascular, abdominal, or peripheral arterial) participated in a randomized trial investigating the effect of nursing care, as compared with usual care, on vascular risk factors. Nursing care consisted of self-efficacy promotion and medical treatment of vascular risk factors. Self-efficacy and vascular risk factors (smoking, BMI, waist, blood pressure, lipid, and glucose levels) were measured at baseline and after 1 year. RESULTS: While total self-efficacy did not change over the 1-year intervention period in either treatment group, self-efficacy in choosing healthy food (mean +0.4+/-1.4, p-value 0.01) and in doing extra exercise (mean +0.3+/-1.3, p-value 0.03) increased in the intervention group. No relation was seen between baseline total self-efficacy or change in composite self-efficacy and change in vascular risk factors. CONCLUSION: The nursing intervention did not influence total self-efficacy but did improve self-efficacy in choosing healthy food and doing extra exercise. Change in composite self-efficacy was not related to change in vascular risk factors in patients at high risk of developing (new) cardiovascular diseases. PRACTICE IMPLICATIONS: Influencing self-efficacy in choosing healthy food and doing extra exercise could be incorporated in vascular risk reduction programs in addition to medical treatment of vascular risk factors.

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. Trial registration NCT01460459, registered 10-2011, recruitment between 05-2011 and 12-2011.

Self-efficacy in patients with clinical manifestations of vascular diseases.

OBJECTIVE: Patients with established cardiovascular disease are at high risk of developing new vascular events or death. This risk can be reduced by lifelong treatment of risk factors and by permanent changes in lifestyle. Self-efficacy is important for achieving behavior change by self-management. The self-efficacy of different vascular risk factors subgroups in patients with clinical manifestations of atherosclerotic vascular diseases was investigated. METHODS: From January 2001 to September 2003, 192 patients with recently established clinically manifest atherosclerotic disease with > or = 2 modifiable vascular risk factors were selected for the study. The mean self-efficacy scores were calculated for vascular risk factors (age, sex, vascular disease, weight, diabetes mellitus, smoking behavior, hypercholesterolemia, hypertension, and hyperhomocysteinemia). RESULTS: Diabetes, overweight, and smoking, but none of the other risk factors, were significantly associated with the level of self-efficacy in these patients. CONCLUSIONS: Patients with vascular diseases appear to have high levels of self-efficacy regarding medication use, exercise, and controlling weight. In patients with diabetes, overweight, and in smokers, self-efficacy levels were lower. PRACTICE IMPLICATIONS: In nursing care and research on developing self-efficacy based interventions, lower self-efficacy levels can be taken into account for specific vascular patient groups.

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. OBJECTIVES: Study aim was to adapt a Dutch/English version of the diabetes management self-efficacy (SE) scale for use with a Turkish population and evaluate its psychometric properties. DESIGN: Methodological research design. SETTINGS: Attendants of an outpatient clinic of a university hospital in Turkey. PARTICIPANTS: A convenience sample of 110 patients with type 2 diabetes mellitus (DM). METHODS: Translation and back-translation of the original English instrument and content validation through a expert panel were the first two steps of the study. Third step was the psychometric testing of the adapted instrument by establishing internal consistency (Cronbach's alpha), stability (test-retest reliability), and construct validity (factor analysis). RESULTS: Content validity procedure resulted in a final scale that consisted of 20 items. Internal consistency of the total scale was coefficient alpha=0.88, and test-retest reliability with a 4-week time interval was r=0.91 (p<0.001). Factor analysis yielded three factors related to diet, exercise and medical treatment. Two relevant items of the scale, weight control and blood sugar control, however, had low reliability and validity scores. CONCLUSIONS: Although acceptable levels of reliability and validity of the Turkish version of the diabetes management SE scale for people with type 2 DM were reached, cultural factors appeared to play a role in the applicability of some items of the scale.

Vascular risk management through nurse-led self-management programs.

In current clinical practice, adequate cardiovascular risk reduction is difficult to achieve. Treatment is primarily focused on clinical vascular disease and not on long-term risk reduction. Pertinent to success in vascular risk reduction are proper medication use, weight control, healthy food choices, smoking cessation, and physical exercise. Atherosclerotic vascular disease and its risk constitute a chronic condition, which poses specific requirements on affected patients and caregivers who should be aware of the chronicity. In patients with vascular disease, there is lack of awareness of their chronic condition because of the invisibility of most risk factors. In other patient groups with chronic illness, self-management programs were successful in achieving behavioral change. This strategy can also be useful for patients with vascular disease to adapt and adhere to an improved lifestyle. Self-management refers to the individual's ability to manage both physical and psychosocial consequences including lifestyle changes inherent to living with a chronic condition. Interventions that promote self-management are based on enhancing self-efficacy. In self-management, attention can be given to what is important and motivational to the individual patient. In this article the challenge of nursing care promoting self-management for patients with vascular risk and how this care can be applied will be explained. Nurses can play a central role in vascular risk management with a self-management approach for patients with chronic vascular disease. In vascular prevention clinics, nursing care can be delivered that includes medical treatment of vascular risks (hypertension, hypercholesterolemia, hyperglycemia, and hyperhomocystinemia) and counseling on promoting self-management (changes in diet, body weight, smoking habits, and level of exercise). Nursing interventions based on self-management promotion can provide a new and promising approach to actually achieve vascular risk reduction.

Development and Validation of the Perception of Self-Monitoring of Blood Glucose Scale in Insulin-Treated Patients With Diabetes.

BACKGROUND AND PURPOSE: The Perception of Self-Monitoring of Blood Glucose (P-SMBG) scale was developed and validated to assess perceptions of self-monitoring of blood glucose (SMBG) in insulin-treated patients with diabetes. METHOD: An initial 68-item version of the P-SMBG has been evaluated by a panel of professionals and patients. A sample of 375 patients tested the revised scale. RESULTS: Factor analysis suggested a 19-item scale and a 2-factor structure, separating negatively and positively worded items. Cronbach's alpha was .84 and .72, and the intraclass correlation coefficient was .66 and .57, respectively for both factors. Item-total correlations were in the range of .23-.66. Convergent/divergent validity was confirmed for the negatively worded items. CONCLUSIONS: The final P-SMBG scale (21 items) can be used to assess positive and negative perceptions of SMBG in insulin-treated patients with diabetes.

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.

Alone together: A grounded theory study of experienced burden, coping, and support needs of spouses of persons with a bipolar disorder.

Bipolar disorder is a chronic and severe mental disorder. Little is known about the experiences of the spouses of such patients. A grounded theory study was undertaken to examine the burden for spouses living with a partner with a bipolar disorder and to explore how they cope and what support they need. Fifteen spouses and ex-spouses were interviewed; they experienced heavy burden and found themselves to be 'alone together.' Their coping process is found to involve appraisal of the situation and attempts to achieve a balance between self-effacement and self-fulfilment. While support can clearly reduce experienced burden, the spouses surprisingly receive virtually no professional support. A theory is developed that constitutes a starting point for the development of adequate support for spouses.
