A longitudinal study of veterinary students and recent graduates 2. Views of the veterinary profession

Objective To examine the development of attitudes and opinions relating to the veterinary profession.
Design Longitudinal study.
Population Students, 154 in all, who began studying veterinary science at The University of Queensland in 1985 and 1986.
Procedure Questionnaires were completed in the first and fifth year of the course and in the second year after graduation. The data were analysed using the SAS System for Windows.
Results Few changes in opinion over time were found on the role of the profession, or on the status and prestige of veterinarians. Changes did occur in views on the characteristics of a successful veterinarian, with increases in the perceived importance of interpersonal skills, and of the capacity to work hard, and decreases in the perceived importance of honesty and integrity, dedication and the prevention of cruelty. Attitudes hardened over time in relation to costs of treatment, non-payment of fees and availability out of hours. Individuals changed their opinion on whether to counsel or report an incompetent colleague, but the changes in one direction were approximately equal to those in the opposite direction.
Conclusions The attitudes and opinions of veterinary graduates result from experiences before and during their veterinary course. In general the perceived importance of interpersonal skills increases during the course, and the level of altruism decreases.     

Immune-mediated haemolytic anaemia in 110 dogs in Victoria, Australia

Objective   Evaluate the survival and prognostic indicators (i.e. breed predilection, season, blood transfusion, and the prevalence of autoagglutination) of dogs with immune-mediated haemolytic anaemia (IMHA) in Victoria, Australia.
Design   Retrospective study of 110 diagnosed with primary IMHA at the University of Melbourne Veterinary Clinic and Hospital.
Results   In total, 80 of the dogs (72.7%) were discharged from hospital and 48 of 65 (73.8%) dogs available for follow-up were known to be alive at 1 year, giving an overall 1-year survival of 48 (50.5%) of 95 dogs for which survival data were available. Regarding breed, 80 (18.2%) of the 110 dogs were Maltese-breed dogs compared with 81 (7.4%) of 1100 control dogs (P < 0.001). Springer Spaniels (P = 0.02), Hungarian Vizslas (P = 0.02) and Airedale Terriers (P < 0.001) were also over-represented compared with the control sample. There was no evidence of an association between the occurrence of IMHA in dogs and season in this study. Receiving one or more blood transfusions did not affect survival to the time of discharge from hospital. On initial blood smear examination, 57 (51.8%) of the 110 dogs had spontaneous autoagglutination and its presence was associated with decreased survival to discharge from hospital (P = 0.03). Packed cell volume, white cell count, platelet count and serum total bilirubin on admission had no effect on survival to the time of discharge from hospital or 1 year later.
Conclusion   Dogs with IMHA have a guarded prognosis as only half are still alive 1 year after the acute event.     

A longitudinal study of veterinary students and recent graduates 4. Gender issues

Objective To study differences in experiences, attitudes and opinions between female and male veterinary students and recent graduates.
Design Longitudinal study.
Population Students – 77 males and 77 females – who began studying veterinary science at The University of Queensland in 1985 and 1986.
Procedure Questionnaires were completed in the first and fifth year of the course, and in the second year after graduation. The data were analysed using the SAS System for Windows.
Results Females decided to study veterinary science at a younger age than males and were more influenced by 'a love of animals', the image of veterinarians as portrayed on television, an interest in living things and in the scientific study of disease. Males were more influenced than females in aspects of the workplace: bosses and money. There were no gender differences in their background in relation to farms, or to animals, or in their career plans. However females when in first year expected a lower initial income than males; an expectation that was realised in the first year after graduation. As first year students and also as veterinarians, females had stronger views than males on animal welfare issues, and also felt that the veterinary profession had a lower status relative to other professions.
Conclusions Significant differences in attitudes and experiences exist between males and females entering the veterinary profession. The situation of females in relation to income and status is consistent with that in other professions, where females have been disadvantaged compared with males.
