A retrospective study of clinical findings, treatment and outcome in 143 dogs with pericardial effusion.

A retrospective study of 143 dogs with pericardial effusion is presented, including a statistical analysis of survival time. Cases were classified into those in which a mass was seen on echocardiography (echo-positive) and those in which no mass could be identified (echo-negative). Forty-four dogs were echo-positive and 99 were echo-negative. The median survival time (MST) was 1068 days for echo-negative dogs and 26 days for echo-positive dogs. Dogs with a history of collapse were more likely to present with a mass on echocardiography. Those presenting with collapse had an MST of 30 days compared with 605 days for those without collapse. Echo-negative dogs tended to present with ascites and generally had a larger volume of pericardial effusion. The median survival for dogs presenting with ascites was 605 days compared with 45 days for those without ascites. Among echo-negative dogs, 64 per cent had a relapse of their effusion. Subtotal pericardiectomy was performed in 31 echo-negative dogs. The procedure had a perioperative mortality of 13 per cent but provided a favourable long-term prognosis. Dogs undergoing pericardiectomy had a median survival of 1218 days compared with 532 days for those not undergoing surgery.

Development and validation of a questionnaire to evaluate the effectiveness of evidence-based practice teaching.

AIM: The aim of this study was to develop and validate a questionnaire to evaluate the effectiveness of evidence-based practice (EBP) teaching. METHODS: The 152 questionnaires completed by health care professionals with a range of EBP experience were used in this study. Cronbach's alpha for the knowledge and attitude questions indicated a satisfactory level of internal consistency (i.e. >0.60). RESULTS: The discriminative validity was evidenced by a statistically significant difference in the knowledge and attitude scores of 'novices' (i.e. little or no prior EBP education) compared with 'experts' (i.e. health care professionals and academics currently teaching EBP). Moderate to good (> or =0.4) sensitivity index scores were observed for both knowledge and attitude scores as the result of comparing individuals before and after an EBP intervention. CONCLUSIONS: The results of this validation study indicate that the developed questionnaire is a satisfactory tool with which to evaluate the effectiveness of EBP teaching interventions.

A systematic review of the effectiveness of critical appraisal skills training for clinicians.

The aim of this paper is to undertake a descriptive systematic review of the effectiveness of critical appraisal skills training for clinicians. Of the 10 controlled studies which examined this issue and were found to meet the eligibility criteria of this review, all used a study population of either medical students or doctors in training. The studies used a variety of different intervention 'dosages' and reported a range of outcomes. These included participants' knowledge of epidemiology/biostatistics, their attitudes towards medical literature, their ability to appraise medical literature, and medical literature reading behaviour. An overall improvement in assessed outcomes of 68% was reported after critical appraisal skills training, particularly in knowledge relating to epidemiology and biostatistics. This review appears to provide some evidence of the benefit of teaching critical appraisal skills to clinicians, in terms of both knowledge of methodological/statistical issues in clinical research and attitudes to medical literature. However, these findings should be considered with caution as the methodological quality of studies was generally poor, with only one study employing a randomized controlled design. There is a need for educators within the field of evidence-based health to consider the implications of this review.

Studies on natural transmission of Bordetella bronchiseptica in cats.

Two pregnant specific-pathogen-free (SPF) cats, from a colony endemically infected with Bordetella bronchiseptica, were housed under barrier conditions in the latter stages of pregnancy in order to study the possible transmission of the organism to their kittens. Both queens had antibody titres to Bordetella bronchiseptica of 1 in 320 at the start of the experiment but did not shed Bordetella bronchiseptica until 9 days and 6 weeks after parturition, respectively. Five of the nine kittens had detectable maternally-derived-antibody to Bordetella bronchiseptica which declined to < or = 1 in 40 by two weeks of age. Kittens were weaned at 12 weeks of age. No Bordetella bronchiseptica was isolated from any of the kittens and none seroconverted over this time. At 15 1/2 weeks of age, half of each litter were housed separately and inoculated intra-nasally with 10(8) colony-forming-units B. bronchiseptica. Mild signs of upper respiratory tract disease were seen and the organism was isolated for 19 weeks following inoculation when the experiment ended. Seroconversion occurred at 4 weeks postinoculation. Oral treatment of two clinically-recovered kittens with doxycycline once a day did not eliminate shedding.
