Radiographers in Oman are believed to be engaged with varying levels of role extension however the nature and extent of this currently unknown. The aim of this study was to investigate role extension for radiographers in Oman, and to evaluate radiographers and the radiologists’ opinions and attitudes toward role extension. Methods A cross sectional study of radiographers and radiologists at 13 major hospitals in Oman was used. A total of 189 radiographers and 77 radiologists were invited to complete a questionnaire seeking information on current and possible future role extension activities. Results The overall response rate was 80.4% for radiographers and 63.6% for radiologists. Approximately half (53.3%) of the radiographer respondents reported they carry out examinations traditionally performed by radiologists (i.e. role extension); this was primarily in gastrointestinal and barium enema studies. Fewer (21%) reported being involved in image interpretation, most commonly in accident and emergency examinations. Forty percent of radiographers reported involvement in intravenous injections, most commonly for CT and intravenous urography procedures. Both radiographers and radiologists supported the involvement of radiographers in a range of examination types however responses vary within and between hospitals. Conclusion This study concluded that radiography role extension activities are widely implemented at hospitals in Oman and that radiographers have sufficient skills and education for participating in these activities. Implications for practice The involvement of radiographers in role extension activities is believed to be cost and time effective, improve teamwork and has potential for significant service delivery benefits.
