The course of newly presented unexplained complaints in general practice patients: a prospective cohort study

Objective. Newly presented unexplained complaints (UCs) are common in general practice. Factors influencing the transition of newly presented into persistent UCs have been scarcely investigated. We studied the number and the nature of diagnoses made over time, as well as factors associated with UCs becoming persistent. Finally, we longitudinally studied factors associated with quality of life (QoL). Methods. Prospective cohort study in general practice of patients presenting with a new UC. Data sources were case record forms, patient questionnaires and electronic medical registries at inclusion, 1, 6 and 12 months. Presence of complaints and diagnoses made over time were documented. Potential risk factors were assessed in mixed-effect logistic and linear regression models. Results. Sixty-three GPs included 444 patients (73% women; median age 42) with unexplained fatigue (70%), abdominal complaints (14%) and musculoskeletal complaints (16%). At 12 months, 43% of the patients suffered from their initial complaints. Fifty-seven percent of the UCs remained unexplained. UCs had (non-life-threatening) somatic origins in 18% of the patients. QoL was often poor at presentation and tended to remain poor. Being a male [odds ratio (OR) 0.6; 95% confidence interval (CI) 0.4-0.8] and GPs' being more certain about the absence of serious disease (OR 0.9; 95% CI 0.8-0.9) were the strongest predictors of a diminished probability that the complaints would still be present and unexplained after 12 months. The strongest determinants of complaint persistence [regardless of (un)explicability] were duration of complaints >4 weeks before presentation (OR 2.6; 95% CI 1.6-4.3), musculoskeletal complaint at baseline (OR 2.3; 1.2-4.5), while the passage of time acted positively (OR 0.8 per month; 95% CI 0.78-0.84). Musculoskeletal complaints, compared to fatigue, decreased QoL on the physical domain (4.6 points; 2.6-6.7), while presence of psychosocial factors decreased mental QoL (5.0; 3.1-6.9). Conclusion. One year after initial presentation, a large proportion of newly presented UCs remained unexplained and unresolved. We identified determinants that GPs might want to consider in the early detection of patients at risk of UC persistence and/or low Qo

A monitoring and feedback tool embedded in a counselling protocol to increase physical activity of patients with COPD or type 2 diabetes in primary care: study protocol of a three-arm cluster randomised controlled trial

BACKGROUND: Physical activity is important for a healthy lifestyle. Although physical activity can delay complications and decrease the burden of the disease, the level of activity of patients with chronic obstructive pulmonary disease (COPD) or type 2 Diabetes Mellitus (DM2) is often far from optimal. To stimulate physical activity, a monitoring and feedback tool, consisting of an accelerometer linked to a smart phone and webserver (It’s LiFe! tool), and a counselling protocol for practice nurses in primary care was developed (the Self-management Support Program). The main objective of this study is to measure the longitudinal effects of this counselling protocol and the added value of using the tool. METHODS/DESIGN: This three-armed cluster randomised controlled trial with 120 participants with COPD and 120 participants with DM2 (aged 40–70), compares the counselling protocol with and without the use of the tool (group 1 and 2) with usual care (group 3). Recruitment takes place at GP practices in the southern regions of the Netherlands. Randomisation takes place at the practice level. The intended sample (three arms of 8 practices) powers the study to detect a 10-minute difference of moderate and intense physical activity per day between groups 1 and 3. Participants in the intervention groups have to visit the practice nurse 3–4 times for physical activity counselling, in a 4-6-month period. Specific activity goals tailored to the individual patient's preferences and needs will be set. In addition, participants in group 1 will be instructed to use the tool in daily life. The primary outcome, physical activity, will be measured in all groups with a physical activity monitor (PAM). Secondary outcomes are quality of life, general - and exercise - self-efficacy, and health status. Follow-up will take place after 6 and 9 months. Separately, a process evaluation will be conducted to explore reasons for trial non-participation, and the intervention’s acceptability for participating patients and nurses. DISCUSSION: Results of this study will give insight into the effects of the It’s LiFe! monitoring and feedback tool combined with care from a practice nurse for people with COPD or DM2 on physical activity.

Gender sensitivity among general practitioners: Results of a training programme

Contains fulltext : 70167.pdf (publisher's version ) (Open Access)BACKGROUND: Gender differences contribute to patients' health and illness. However in current healthcare practices attention to gender differences is still underdeveloped. Recognizing these differences and taking them into account can improve the quality of care. In this study we aimed to investigate whether GPs' gender sensitivity can be stimulated by a training programme. The focus was on three diseases: angina pectoris, depression and urinary incontinence. METHODS: This study had a quantitative, explorative and descriptive design. By means of a training programme 18 GPs were trained to focus on gender-sensitive recommendations for the three diseases. With standardised registration forms, data were collected during a 6-month period. During the registration period, the GPs were visited by the study team to discuss the process of data collection. RESULTS: The GPs filled in registration forms for 100 patients: 39 with angina pectoris (31 women and 8 men), 40 with depression (26 women and 14 men), and 21 with urinary incontinence (20 women and 1 man). The results show that gender sensitivity can be stimulated among trained professionals. The combination of the training programme, clear and practical recommendations, daily discussion of relevant cases between the GP couples, feedback and support during registration by the study team probably contributed to the outcome. CONCLUSION: GPs' gender sensitivity was stimulated by the training programme and the supporting visits. Ideally, structural attention could be realised by embedding gender issues in existing organisational structures of general practices

Metabolic enhancement of mammalian developmental pausing

The quest to model and modulate embryonic development became a recent cornerstone of stem cell and developmental biology. Mammalian developmental timing is adjustable in vivo by preserving preimplantation embryos in a dormant state called diapause. Inhibition of the growth regulator mTOR (mTORi) pauses mouse development in vitro, yet constraints to pause duration are unrecognized. By comparing the response of embryonic and extraembryonic stem cells to mTORi-induced pausing, we identified lipid usage as a bottleneck to developmental pausing. Enhancing fatty acid oxidation (FAO) boosts embryo longevity, while blocking it reduces the pausing capacity. Genomic and metabolic analyses of single embryos point toward a deeper dormant state in FAO-enhanced pausing and reveal a link between lipid metabolism and embryo morphology. Our results lift a constraint on in vitro embryo survival and suggest that lipid metabolism may be a critical metabolic transition relevant for longevity and stem cell function across tissues

Arduous implementation: Does the Normalisation Process Model explain why it's so difficult to embed decision support technologies for patients in routine clinical practice

Background: decision support technologies (DSTs, also known as decision aids) help patients and professionals take part in collaborative decision-making processes. Trials have shown favorable impacts on patient knowledge, satisfaction, decisional conflict and confidence. However, they have not become routinely embedded in health care settings. Few studies have approached this issue using a theoretical framework. We explained problems of implementing DSTs using the Normalization Process Model, a conceptual model that focuses attention on how complex interventions become routinely embedded in practice.Methods: the Normalization Process Model was used as the basis of conceptual analysis of the outcomes of previous primary research and reviews. Using a virtual working environment we applied the model and its main concepts to examine: the 'workability' of DSTs in professional-patient interactions; how DSTs affect knowledge relations between their users; how DSTs impact on users' skills and performance; and the impact of DSTs on the allocation of organizational resources.Results: conceptual analysis using the Normalization Process Model provided insight on implementation problems for DSTs in routine settings. Current research focuses mainly on the interactional workability of these technologies, but factors related to divisions of labor and health care, and the organizational contexts in which DSTs are used, are poorly described and understood.Conclusion: the model successfully provided a framework for helping to identify factors that promote and inhibit the implementation of DSTs in healthcare and gave us insights into factors influencing the introduction of new technologies into contexts where negotiations are characterized by asymmetries of power and knowledge. Future research and development on the deployment of DSTs needs to take a more holistic approach and give emphasis to the structural conditions and social norms in which these technologies are enacte
