Effects of self-monitoring of glucose on distress and self-efficacy in people with non-insulin-treated Type 2 diabetes: a randomized controlled trial.

AIMS: To investigate the effects of self-monitoring of glucose in blood or urine, on diabetes-specific distress and self-efficacy, compared with usual care in people with non-insulin-treated Type 2 diabetes mellitus. METHODS: One hundred and eighty-one participants with non-insulin-treated Type 2 diabetes mellitus [diabetes duration ≥ 1 year, age 45-75 years, HbA1c ≥ 53.0 mmol/mol (7.0%), self-monitoring frequency < 3 times in the previous year] were randomly assigned to blood self-monitoring (n = 60), urine self-monitoring (n = 59) or usual care (n = 62). Primary outcomes were between-group differences in diabetes-specific distress [Problem Areas in Diabetes scale (PAID)] and self-efficacy [Confidence in Diabetes Self-Care questionnaire (CIDS-2)] after 12 months. Secondary outcomes included changes in HbA1c , treatment satisfaction and depressive symptoms. RESULTS: There were no statistically significant between-group differences in changes in PAID and CIDS-2 after 12 months. Mean difference in PAID between blood monitoring and control was -2.2 [95% confidence interval (CI) -7.1 to 2.7], between urine monitoring and control was -0.9 (95% CI -4.4 to 2.5) and between blood monitoring and urine monitoring was -2.0 (95% CI -4.1 to 0.1). Mean difference in CIDS-2 between blood monitoring and control was 0.6 [95% CI (-2.0 to 2.1), between urine monitoring and control was 2.8 (95% CI -2.3 to 7.9)] and between blood monitoring and urine monitoring was -3.3 (95% CI -7.9 to 1.3). No statistically significant between-group differences in change in any of the secondary outcome measures were found. CONCLUSIONS: This study did not find statistical or clinical evidence for a long-term effect of self-monitoring of glucose in blood or urine on diabetes-specific distress and self-efficacy in people with moderately controlled non-insulin-treated Type 2 diabetes mellitus.

Perspectives of obese children and their parents on lifestyle behavior change: a qualitative study.

BACKGROUND: In order to improve and optimize future behavioral family lifestyle intervention programs, more information on the perceptions of obese children and their parents of these programs is needed. As such, the aim of this qualitative study is 1) to explore the expectations of obese children and their parents in relation to lifestyle interventions; 2) to identify barriers to making lifestyle changes that parents and children face within their social context (within the family, at school and amongst friends and peers) as well as the things that facilitate these changes and 3) to identify the needs of obese children and their parents in the context of a lifestyle intervention. METHODS: A qualitative study using semi-structured interviews was conducted. Interviewees were participants in a lifestyle intervention program in the Netherlands. RESULTS: Eighteen children (mean age 10 years) and 24 parents were interviewed. The respondents expected to lose weight by being physically active or by eating healthily. Parents struggled with adopting and adhering to new rules and the absence of support of family members. Children struggled with inconsistent parenting and a lack of support from their parents. Bullying experienced at school impeded the children in their ability to make the necessary changes. Support from peers, on the other hand, stimulated their progress. Parents identified the need for the general practitioner to discuss overweight in a non-offensive way and to show an interest in the process of weight loss. CONCLUSIONS: Participants in a lifestyle behavior intervention program benefit from parental support and help from their (extended) family, peers and friends. They would also profit from the sustained involvement of their general practitioner in assisting in the maintenance of lifestyle behavior changes.

[Lessons learned from the implementation of Dutch national healthcare guidelines on childhood obesity]. / Lessen geleerd van de implementatie van Zorgstandaard Obesitas voor kinderen.

OBJECTIVE: To describe the implementation and feasibility of the national healthcare guidelines on childhood obesity in a region with a high prevalence of overweight and obesity in children. DESIGN: Descriptive, implementation study. METHOD: The implementation of the guidelines took place in the borough Amsterdam West. In total, 17 general practitioners (GP) from the Academic General Practice Network (ANH) of the VU University Medical Center, Amsterdam, participated in the study, along with 19 child healthcare practitioners and 3 paediatricians. A number of measures were taken to promote implementation. Feasibility was evaluated using both qualitative and quantitative methods. RESULTS: The participating healthcare providers found the training in application of the guidelines and case study discussions useful. GPs found that their role as central caregiver was not feasible. All participants expressed a preference for child healthcare practitioners as the central caregiver. A total of 327 obese children were invited to attend the GP's surgery; only 65 of them participated in the study and only 28 children were monitored for a whole year. Collaboration agreements between involved healthcare providers were rarely fulfilled. CONCLUSION: Implementation of the national healthcare guidelines on childhood obesity in the current form appears not to be feasible in Amsterdam West, despite the many implementation-enhancing measures that were applied. It is questionable whether the national healthcare guidelines on childhood obesity in its current form can contribute to addressing the societal problem of overweight and obesity in children.

Internal consistency and validity of a new physical workload questionnaire.

AIMS: To examine the dimensionality, internal consistency, and construct validity of a new physical workload questionnaire in employees with musculoskeletal complaints. METHODS: Factor analysis was applied to the responses in three study populations with musculoskeletal disorders (n = 406, 300, and 557) on 26 items related to physical workload. The internal consistency of the resulting subscales was examined. It was hypothesised that physical workload would vary among different occupational groups. The occupations of all subjects were classified into four groups on the basis of expected workload (heavy physical load; long lasting postures and repetitive movements; both; no physical load). Construct validity of the subscales created was tested by comparing the subscale scores among these occupational groups. RESULTS: The pattern of the factor loadings of items was almost identical for the three study populations. Two interpretable factors were found: items related to heavy physical workload loaded highly on the first factor, and items related to static postures or repetitive work loaded highly on the second factor. The first constructed subscale "heavy physical work" had a Cronbach's alpha of 0.92 to 0.93 and the second subscale "long lasting postures and repetitive movements", of 0.86 to 0.87. Six of eight hypotheses regarding the construct validity of the subscales were confirmed. CONCLUSIONS: The results support the internal structure, internal consistency, and validity of the new physical workload questionnaire. Testing this questionnaire in non-symptomatic employees and comparing its performance with objective assessments of physical workload are important next steps in the validation process.

The incidences of and consultation rate for lower extremity complaints in general practice.

OBJECTIVE: To estimate the incidence and consultation rate of lower extremity complaints in general practice. METHODS: Data were obtained from the Second Dutch National Survey of General Practice, in which 195 general practitioners (GPs) in 104 practices recorded all contacts with patients during 12 consecutive months in computerised patient records. GPs classified the symptoms and diagnosis for each patient at each consultation according to the International Classification of Primary Care (ICPC). Incidence densities and consultation rates for different complaints were calculated. RESULTS: During the registration period 63.2 GP consultations per 1000 person-years were attributable to a new complaint of the lower extremities. Highest incidence densities were seen for knee complaints: 21.4 per 1000 person-years for women and 22.8 per 1000 person-years for men. The incidence of most lower extremity complaints was higher for women than for men and higher in older age. CONCLUSIONS: Both incidences of and consultation rates for lower extremity complaints are substantial in general practice. This implies a considerable impact on the workload of the GP.

Course and prognosis of elbow complaints: a cohort study in general practice.

OBJECTIVE: To describe the course of new episodes of elbow complaints in general practice, and to identify predictors of short term and long term outcome in terms of pain intensity and functional disability. METHODS: 181 patients with elbow complaints filled in questionnaires at baseline and at 3, 6, and 12 months of follow up. Baseline scores of pain and disability, characteristics of the complaint, sociodemographic and psychosocial factors, physical activity, general health, and comorbidity were investigated as possible predictors of outcome. Outcome measures were analysed separately using multiple regression analyses. RESULTS: 13% of the patients reported recovery at the 3 month follow up and 34% at 12 months. Irrespective of outcome and length of follow up, a longer duration of the complaint before consulting the general practitioner, having musculoskeletal comorbidity, and using "retreating" as coping style increased the likelihood of an unfavourable outcome. Less social support was associated with an unfavourable outcome at 3 months, and having a history of elbow complaints and using "worrying" as coping style were associated with an unfavourable outcome at 12 months. The explained variance of the models ranged from 46% to 49%. CONCLUSIONS: Recovery of patients with elbow complaints in general practice was poor. Besides characteristic of the complaint, passive coping and less social support were related to a worse prognosis. The results of this study may help general practitioners to provide patients with more accurate information about their prognosis.

Incidence and prevalence of complaints of the neck and upper extremity in general practice.

OBJECTIVE: To study the incidence and prevalence of neck and upper extremity musculoskeletal complaints in Dutch general practice. METHODS: Data were obtained from the second Dutch national survey of general practice. In all, 195 general practitioners (GPs) from 104 practices across the Netherlands recorded all contacts with patients during 12 consecutive months. Incidence densities and consultation rates were calculated. RESULTS: The total number of contacts during the registration period of one year was 1 524 470. The most commonly reported complaint was neck symptoms (incidence 23.1 per 1000 person-years), followed by shoulder symptoms (incidence 19.0 per 1000 person-years). Sixty six GP consultations per 1000 person-years were attributable to a new complaint or new episode of complaint of the neck or upper extremity (incidence density). In all, the GPs were consulted 147 times per 1000 registered persons for complaints of the neck or upper extremity. For most complaints the incidence densities and consultation rates were higher for women than for men. CONCLUSIONS: Neck and upper extremity symptoms are common in Dutch general practice. The GP is consulted approximately seven times each week for a complaint relating to the neck or upper extremity; of these, three are new complaints or new episodes. Attention should be paid to training GPs to deal with neck and upper limb complaints, and to research on the prognosis and treatment of these common complaints in primary care.

Clinimetric evaluation of shoulder disability questionnaires: a systematic review of the literature.

OBJECTIVE: To identify all available shoulder disability questionnaires designed to measure physical functioning and to evaluate evidence for the clinimetric quality of these instruments. METHODS: Systematic literature searches were performed to identify self administered shoulder disability questionnaires. A checklist was developed to evaluate and compare the clinimetric quality of the instruments. RESULTS: Two reviewers identified and evaluated 16 questionnaires by our checklist. Most studies were found for the Disability of the Arm, Shoulder, and Hand scale (DASH), the Shoulder Pain and Disability Index (SPADI), and the American Shoulder and Elbow Surgeons Standardised Shoulder Assessment Form (ASES). None of the questionnaires demonstrated satisfactory results for all properties. Most questionnaires claim to measure several domains (for example, pain, physical, emotional, and social functioning), yet dimensionality was studied in only three instruments. The internal consistency was calculated for seven questionnaires and only one received an adequate rating. Twelve questionnaires received positive ratings for construct validity, although depending on the population studied, four of these questionnaires received poor ratings too. Seven questionnaires were shown to have adequate test-retest reliability (ICC >0.70), but five questionnaires were tested inadequately. In most clinimetric studies only small sample sizes (n<43) were used. Nearly all publications lacked information on the interpretation of scores. CONCLUSION: The DASH, SPADI, and ASES have been studied most extensively, and yet even published validation studies of these instruments have limitations in study design, sample sizes, or evidence for dimensionality. Overall, the DASH received the best ratings for its clinimetric properties.
