Effectiveness of a short-course in improving knowledge and skills on evidence-based practice.

BACKGROUND: To assess the effectiveness (change in knowledge and skills measured by the Fresno test) of a short course in Evidence Based Practice (EBP) carried out in a group of family medicine residents METHODS: Before-after study. Participants' were 152 Family Medicine residents in their second year of the training programme. Settings were Primary Care Teaching Units in Catalonia. Intervention was comprised of a four half-day training course designed to develop the knowledge and skills required to practice evidence-based care. The main outcome measure was change in EBP knowledge and skills, measured using the Spanish version of the Fresno test (score range, 0-212) RESULTS: The mean difference between pre-test and post-test was 47.7, a statistically significant result with 95% CI of 42.8-52.5 (p < 0.0001). An important improvement was observed in the questions related to calculations such as sensitivity, specificity, the absolute risk reduction or the number needed to treat. A more modest increase was found in the residents' knowledge and skills in finding the best clinical evidence, and appraising the validity and applicability of an article. Finally, a weak and non-statistically significant improvement was found in formulating a clinical question. CONCLUSIONS: The study provides evidence for responsiveness to changes in knowledge and skills in EBP after an educational intervention.

Psychometric properties of a test in evidence based practice: the Spanish version of the Fresno test.

BACKGROUND: Validated instruments are needed to evaluate the programmatic impact of Evidence Based Practice (EBP) training and to document the competence of individual trainees. This study aimed to translate the Fresno test into Spanish and subsequently validate it, in order to ensure the equivalence of the Spanish version against the original English version. METHODS: Before and after study performed between October 2007 and June 2008. Three groups of participants: (a) Mentors of family medicine residents (expert group) (n = 56); (b) Family medicine physicians (intermediate experience group) (n = 17); (c) Family medicine residents (novice group) (n = 202); Medical residents attended an EBP course, and two sets of the test were administered before and after the course. The Fresno test is a performance based measure for use in medical education that assesses EBP skills. The outcome measures were: inter-rater and intra-rater reliability, internal consistency, item analyses, construct validity, feasibility of administration, and responsiveness. RESULTS: Inter-rater correlations were 0.95 and 0.85 in the pre-test and the post-test respectively. The overall intra-rater reliability was 0.71 and 0.81 in the pre-test and post-test questionnaire, respectively. Cronbach's alpha was 0.88 and 0.77, respectively. 152 residents (75.2%) returned both sets of the questionnaire. The observed effect size for the residents was 1.77 (CI 95%: 1.57-1.95), the standardised response mean was 1.65 (CI 95%:1.47-1.82). CONCLUSIONS: The Spanish version of the Fresno test is a useful tool in assessing the knowledge and skills of EBP in Spanish-speaking residents of Family Medicine.

Study protocol of psychometric properties of the Spanish translation of a competence test in evidence based practice: the Fresno test.

BACKGROUND: There are few high-quality instruments for evaluating the effectiveness of Evidence-Based Practice (EBP) curricula with objective outcomes measures. The Fresno test is an instrument that evaluates most of EBP steps with a high reliability and validity in the English original version. The present study has the aims to translate the Fresno questionnaire into Spanish and its subsequent validation to ensure the equivalence of the Spanish version against the English original. METHODS AND DESIGN: The questionnaire will be translated with the back translation technique and tested in Primary Care Teaching Units in Catalonia (PCTU). Participants will be: (a) tutors of Family Medicine residents (expert group); (b) Family Medicine residents in their second year of the Family Medicine training program (novice group), and (c) Family Medicine physicians (intermediate group). The questionnaire will be administered before and after an educational intervention. The educational intervention will be an interactive four half-day sessions designed to develop the knowledge and skills required to EBP. Responsiveness statistics used in the analysis will be the effect size, the standardised response mean and Guyatt's method. For internal consistency reliability, two measures will be used: corrected item-total correlations and Cronbach's alpha. Inter-rater reliability will be tested using Kappa coefficient for qualitative items and intra-class correlation coefficient for quantitative items and the overall score. Construct validity, item difficulty, item discrimination and feasibility will be determined. DISCUSSION: The validation of the Fresno questionnaire into different languages will enable the expansion of the questionnaire, as well as allowing comparison between countries and the evaluation of different teaching models.

[Dependence profile in Spain: an analysis from the disability survey of 1999]. / El perfil de la dependencia en España: un análisis de la encuesta de discapacidades de 1999.

BACKGROUND: In the next future an important demographical ageing will imply a rise in the levels of co morbidity, disability and dependence of the population. The objective if this work was to estimate the dependences profile by means of assessing the levels of severity of the disability in the Spanish general population. METHODS: Data come from the disease, disability and health status survey of 1999 of the Spanish Institute for Statistics, which includes 36 limitations with an score of severity (from 0= absence to 4= unable). These limitations were grouped in five kinds of disability, the mean score of severity was computed for each one, and grouped in five levels of dependence. To check the relationship between limitations and severity an analysis of correspondence was performed. To identify the pattern of dependence a multiple correspondence and a clusters analysis were computed using the variables of age, sex, kind of disability and level of dependence. RESULTS: There is a relationship between severity and some limitations (being the limitation on daily activities associated to the highest severity). Five groups of dependent people were identified. Those with lower dependence were middle aged, men and having sensorial disabilities and those with higher dependence were mainly women, older than 80 and with disabilities on mobility and on the activities of daily living. CONCLUSIONS: There are five groups of dependent population and this study allows estimating its frequency among the general population what will be very useful to evaluate the amount of resources necessary to take care of them.
