Impact of deliberate practice on evidence-based medicine attitudes and behaviours of health care professionals.

INTRODUCTION: Although evidence-based medicine (EBM) teaching activities may improve short-term EBM knowledge and skills, they have little long-term impact on learners' EBM attitudes and behaviour. This study examined the effects of learning EBM through stand-alone workshops or various forms of deliberate EBM practice. METHODS: We assessed EBM attitudes and behaviour with the evidence based practice inventory questionnaire, in paediatric health care professionals who had only participated in a stand-alone EBM workshop (controls), participants with a completed PhD in clinical research (PhDs), those who had completed part of their paediatric residency at a department (Isala Hospital) which systematically implemented EBM in its clinical and teaching activities (former Isala residents), and a reference group of paediatric professionals currently employed at Isala's paediatric department (current Isala participants). RESULTS: Compared to controls (n = 16), current Isala participants (n = 13) reported more positive EBM attitudes (p < 0.01), gave more priority to using EBM in decision making (p = 0.001) and reported more EBM behaviour (p = 0.007). PhDs (n = 20) gave more priority to using EBM in medical decision making (p < 0.001) and reported more EBM behaviour than controls (p = 0.016). DISCUSSION: Health care professionals exposed to deliberate practice of EBM, either in the daily routines of their department or by completing a PhD in clinical research, view EBM as more useful and are more likely to use it in decision making than their peers who only followed a standard EBM workshop. These findings support the use of deliberate practice as the basis for postgraduate EBM educational activities.

Implementing evidence-based medicine in a busy general hospital department: results and critical success factors.

Implementing evidence-based medicine (EBM) in a busy hospital department is challenging, but when successful, may contribute to quality of care. This paper is a narrative review of the successes and challenges of deliberate implementation of EBM in a paediatric department in a general teaching hospital in Zwolle, the Netherlands. Key elements in this project were providing basic EBM education to the entire team of consultants and nurse practitioners, structurally embedding EBM activities into our weekly schedule and development of local practice guidelines. This deliberate practice of EBM principles has changed the way we treat common paediatric problems. It likely reduced unwarranted practice variation and promoted a reserved attitude towards the use of unnecessary diagnostics, which might improve delivery of effective, cost-conscious care. The project also positively influenced our group culture and learning environment. In accordance with previous reports, lack of time and reluctance to change routines and habits hindered the practice of EBM in our department. In our experience, these barriers can be overcome by promoting a team-wide endorsement of EBM, a willingness to acknowledge uncertainty and by deliberate practice. If these can be achieved, systematic application of EBM principles in a busy hospital department is feasible and worthwhile.

A multinational study to compare prevalence of atopic dermatitis in the first year of life.

BACKGROUND: Atopic dermatitis (AD) is common in childhood, with peak prevalence in early childhood. However, international comparisons of prevalence have focused on older children. We analysed differences in prevalence rates of AD and the associations with putative risk and protective factors, among infants in two European and two Central American countries. METHODS: In 1-yr old infants participating in the International Study of Wheezing in Infants (EISL), prevalence of AD and putative risk and protective factors were assessed by a questionnaire applied to parents. For each risk/protective factor summary, odds ratios with 95% confidence intervals were calculated by means of random effects meta-analysis. RESULTS: Data from 9803 infants were analysed. AD prevalence varied from 10.6% (Valencia, Spain) to 28.2% (San Pedro Sula, Honduras). Average AD prevalences were lower in Europe (14.2%) than in Central America (18.2%, p < 0.01). Consistent with older children, presence of siblings decreased (OR 0.82 [0.72-0.94]), whereas family history of asthma (OR 1.32 [1.10-1.59]), rhinitis (OR 1.33 [1.14-1.54]) and atopic dermatitis (OR 2.40 [1.89-3.05]) increased the risk of infantile AD. However, gender, family size, breastfeeding and socio-economic status were not associated with AD prevalence. CONCLUSIONS: This study shows almost threefold differences in the prevalence of AD in infancy between countries. Risk and protective factors involved in the expression of infantile AD differ from those in older children, possibly suggesting a different pathophysiology. There is a need for additional international epidemiological surveys on AD in young children, the peak prevalence age of this condition.

Anxiety, depression and self-esteem in children with well-controlled asthma: case-control study.

OBJECTIVE: Although asthma has been linked to psychological morbidity, this relationship may be confounded by poor asthma control. We aimed to compare the prevalence of anxiety, depression and low level of self-esteem in children with well-controlled asthma with that of healthy peers. SETTING: Dedicated asthma clinic in a general hospital. PATIENTS: 70 patients with mostly well-controlled asthma and 70 matched healthy controls. INTERVENTIONS: Comprehensive asthma education, management and follow-up for asthma patients. MAIN OUTCOME MEASURES: Validated Dutch versions of the Childhood Depression inventory (CDI), Revised Fear Survey for Children (RFSC), Self Perception Profile for Children (SPC-C) and Adolescents (SPC-A) and State-Trait Anxiety Inventory for Children (STAIC). Asthma control assessed by asthma control questionnaire. RESULTS: No significant differences were found in total scores between asthmatics and controls (95% CI for difference -0.2 to 2.9 for CDI, -5.9 to 11.2 for RFSC, -19.9 to 6.3 for SPC-C, -24.1 to 5.0 for SPC-A and -2.7 to 0.01 for STAIC). There were also no significant differences between asthmatics and controls in the prevalence of scores exceeding cut-off levels for clinically relevant anxiety (13.3 vs 13.0%, p=0.605), depression (12.9 vs 5.7%, p=0.243) or low self-esteem (21.4 vs 12.9%, p=0.175). A significant correlation was found between poorer asthma control and CDI (p=0.012) and anxiety trait symptoms (p<0.001). CONCLUSIONS: Children with well-controlled asthma enrolled in a comprehensive asthma management programme do not have an increased risk of anxiety, depression and poor self-esteem. Earlier reports of psychological comorbidity in asthma may have been related to inadequately controlled asthma.
