Student radiographers’ knowledge and experience of lateral hip X-ray positioning: A survey

Abstract

Introduction

The horizontal beam lateral (HBL) position technique for X-ray imaging has been used for nearly a century; however, this can be challenging for the patient and the practitioner, as it potentially compromises patient dignity. This study explores student radiographers' knowledge and experience of lateral hip positions and their impact on diagnostic quality and patient dignity.

Method

A cross-sectional mixed-method online survey of undergraduate diagnostic radiography students was completed. Likert scale assessments, rank ordering questions, and free-test qualitative responses were utilised for questions on knowledge and experience of different positioning, ease to obtain, patient dignity, diagnostic quality, and need for repeats. Data analysis included descriptive statistics and cross-tabulation non-parametric analysis against variables of age, gender and year of study.

Results

Responses were received by n = 42/158 students, a response rate of 27%. The HBL position was the most commonly repeated image (76.6%); the qualitative themes included HBL image quality issues and difficulty in the HBL positioning for elderly or frail patients, often in discomfort and pain. Analysis of student responses to perceived patient dignity in positioning identified 73.8% found the HBL undignified, and 85.7% agreed the Clements-Nakayama (CN) position would be more dignified for patients. The diagnostic image quality of the HBL position (64.2%) was compared to the CN alternative axiolateral (66.6%). Comparison of ease of obtaining the correct position for HBL (47.6%) was higher than CN position (28.6%); this could be due to the lack of experience n = 3/42 (7.1%) of this position.

Conclusion

Overall, student radiographers' experience and knowledge of various lateral hip positions observed in clinical practice was good. The CN position scored high for diagnostic image (66.6%) and dignity for the patient (85.7%), over the often repeated HBL position (76.6%), which scored lower for image quality (64.2%) and dignity (76.6%).

Implications for practice

Radiographers should advocate for professional autonomy and explore alternative positioning techniques. Further investigation into the CN position's utilisation, image quality and radiation dose in England is recommended.
