A systematic review of postgraduate teaching in evidence-based medicine and critical appraisal.

Abstract: The knowledge and skills needed for critical literature appraisal and evidence-based practice have not been covered in undergraduate education until recently. These educational needs are, therefore, often met through postgraduate education via courses, workshops and journal clubs. Previous reviews have generally considered postgraduates and undergraduates together. However, there is evidence that the effectiveness of educational interventions varies between postgraduates and undergraduates. In this study the authors therefore examine the effectiveness of evidence-based medicine and critical appraisal teaching at postgraduate level. A comprehensive search was conducted in MEDLINE, EMBASE, ERIC, CCTR, CDSR, DARE, HTA, Best Evidence and SCI. Seventeen studies were identified: two randomized trials, six controlled trials without randomization and nine before-and-after studies. The studies showed a significant improvement in knowledge, but not in attitude, skills or behaviour. However, to draw robust conclusions, well-designed trials are needed that focus on curriculum content and delivery as well as how outcomes are assessed.

The effectiveness of routine dental checks: a systematic review of the evidence base.

Abstract: Aims To systematically review the effectiveness of routine dental checks of different recall frequencies in adults and children. Methods Search methods included electronic bibliographic databases up to March 2001, relevant internet sites, citation checking and contact with experts and professional dental bodies. Inclusion criteria: (1) Study design: any; (2) Population: deciduous, mixed and permanent dentition; (3) Intervention: 'Routine dental check': 'clinical examination, advice, charting (including monitoring of periodontal status) and report' as defined in the NHS Executive General Dental Service Statement of Dental Remuneration; (4) Comparator: no routine dental check or routine dental check(s) of different recall frequency; (5) Primary outcomes: caries, periodontal disease, quality of life, oral cancer. Results Twenty eight studies were identified for the review. Studies were poorly reported and clinically heterogenous which restricted comparison between studies and limited generalisability to the UK situation. There was no consistency across multiple studies in the direction of effect of different dental check frequencies on measures of caries in deciduous mixed or permanent dentition, periodontal disease or oral cancer in permanent dentition. No studies were identified linking empirical measures of quality of life associated with oral health and dental check frequency. Conclusions There is no existing high quality evidence to support or refute the practice of encouraging six-monthly dental checks in adults and children.

Home-based versus hospital-based cardiac rehabilitation after myocardial infarction or revascularisation: design and rationale of the Birmingham Rehabilitation Uptake Maximisation Study (BRUM): a randomised controlled trial [ISRCTN72884263]

Abstract: Cardiac rehabilitation following myocardial infarction reduces subsequent mortality, but uptake and adherence to rehabilitation programmes remains poor, particularly among women, the elderly and ethnic minority groups. Evidence of the effectiveness of home-based cardiac rehabilitation remains limited. This trial evaluates the effectiveness and cost-effectiveness of home-based compared to hospital-based cardiac rehabilitation. A pragmatic randomised controlled trial of home-based compared with hospital-based cardiac rehabilitation in four hospitals serving a multi-ethnic inner city population in the United Kingdom was designed. The home programme is nurse-facilitated, manual-based using the Heart Manual. The hospital programmes offer comprehensive cardiac rehabilitation in an out-patient setting. We will randomise 650 adult, English or Punjabi-speaking patients of low-medium risk following myocardial infarction, coronary angioplasty or coronary artery bypass graft who have been referred for cardiac rehabilitation. Serum cholesterol, smoking cessation, blood pressure, Hospital Anxiety and Depression Score, distance walked on Shuttle walk-test measured at 6, 12 and 24 months. Adherence to the programmes will be estimated using patient self-reports of activity. In-depth interviews with non-attendees and non-adherers will ascertain patient views and the acceptability of the programmes and provide insights about non-attendance and aims to generate a theory of attendance at cardiac rehabilitation. The economic analysis will measure National Health Service costs using resource inputs. Patient costs will be established from the qualitative research, in particular how they affect adherence. More data are needed on the role of home-based versus hospital-based cardiac rehabilitation for patients following myocardial infarction and revascularisation, which would be provided by the Birmingham Rehabilitation Uptake Maximisation Study (BRUM) study and has implications for the clinical management of these patients. A novel feature of this study is the inclusion of non-English Punjabi speakers.

Maternal ante‐natal parameters as predictors of persistent postnatal glucose intolerance: a comparative study between Afro‐Caribbeans, Asians and Caucasians

Abstract: Aims To measure the prevalence of persistent glucose intolerance at 6–12 weeks postpartum in various ethnic groups to assess the value of targeted postpartum screening. Methods A retrospective study was performed using computerized databases from two large maternity units within one UK region. Both units used the same screening strategy for gestational diabetes mellitus (GDM) and the same postpartum follow-up at 6–12 weeks using a 75-g oral glucose tolerance test (OGTT). A total of 221 women with a diagnosis of GDM/impaired glucose tolerance (IGT) in the index pregnancy in addition to a completed postpartum 75-g OGTT were studied. Of these, 91 were Caucasian, 89 were of Indo-Asian (Asian) origin and 41 were of Afro-Caribbean origin. Results The study showed that 35% Indo-Asians had persistent postpartum glucose intolerance compared with 7% Caucasians and 5% Afro-Caribbeans (P < 0.003). Insulin requirement during pregnancy and a diagnosis of gestational diabetes prior to 20 weeks of pregnancy were predictive for persistent postpartum glucose intolerance amongst Indo-Asians. Conclusions The frequency of postpartum glucose intolerance among Indo-Asian women is significantly greater than among age-matched Caucasian and Afro-Caribbean women. We suggest that all Indo-Asian women with gestational diabetes should undergo postpartum screening for persistent glucose intolerance. However, in non-Asian women selective screening may be more cost effective. Diabet. Med. 20, 382–386 (2003)
