Total	223	87	15	325
b
Patient – pain score	HRA clinician - pain score			Total
	0–3	4–6	≥ 7
0–3	103	45	6	154

Clinicians independently assessed the pain after the procedure and made a note before handing the form for the patient to fill-in in private. Pain scale consisted of a numerical visual analogue scale where 0 indicates no pain or discomfort felt by the patient, while 10 indicates severe pain. There is an association between nurse and patient pain scores (Fisher’s exact test p < 0.001). Similarly there is an association between clinician’s and patient’s pain scores (Fisher’s exact test p < 0.001)
