The primary endpoint of the study was a change in patient self-reported 100 mm (10 cm) Visual Analogue Scale (VAS) score for pre-injection anxiety. VAS scale (min=0- max=100 mm (10cm)) 0= no anxiety; 100 mm (10 cm)=very severe anxiety. Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. The 30 gauge needle VAS mean refers to the mean for pre-injection anxiety for that needle size. Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. The 25 gauge needle VAS mean refers to the mean for pre-injection anxiety for that needle size.
The primary endpoint of the study was a change in patient self-reported 100 mm (10 cm) Visual Analogue Scale (VAS) score for post-injection pain.VAS scale (min=0 - max=100 mm (10 cm)) 0= no pain; 100 mm (10 cm)=very severe pain. Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. The 30 gauge needle VAS mean refers to the mean for post-injection pain for that needle size. Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. The 25 gauge needle VAS mean refers to the mean for post-injection pain for that needle size.
Secondary endpoint was assessment of fear of injection based on patient questionnaires completed prior to each injection. The patient will respond to each statement on a scale which ranges from 1 (almost always) to 4 (almost never). Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. Mean describes fear of injection for the 30 gauge needle. Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. Mean describes fear of injection for the 25 gauge needle.
Secondary endpoint was assessment of the perception of the needle based on patient questionnaires completed after each injection. The patient will respond to each statement on a scale which ranges from 1 (strongly agree) to 5 (strongly disagree). A total of 6 statements were given to the participant the more strongly the participant agreed with the statement, the more favorably they perceived the needle. Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. Mean describes perception of the 30 gauge needle. Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. Mean describes perception of the 25 gauge needle.
