Primate veterinarians' knowledge and attitudes regarding pain in macaques

BACKGROUND Assessment of pain in macaques is challenging. The aims of this study were (1) to investigate current knowledge and attitudes of primate veterinarians concerning acute pain in macaques; (2) to synthesise current knowledge and opinion to facilitate pain assessment. A primary question of interest was whether more confident individuals differ in their knowledge and attitudes from less-confident individuals. METHODS An online survey was conducted amongst primate veterinarians serving both laboratories and zoos/sanctuaries. The questionnaire consisted of demographic information, attitudes towards pain, pain rating and analgesics, pain recognition and confidence in recognising pain and sources of information used. RESULTS AND CONCLUSIONS There was generally good use of analgesia by respondents. More confident individuals reported that they recognise pain both behaviourally and in facial expressions, rated all pain signs more highly and used more analgesics. Specialist support networks aimed at increasing veterinarian confidence in macaque pain assessment could be beneficial.
