Brief summary
Arteriovenous fistula is the preferred access for hemodialysis, and cannulation using a button-hole technique is increasingly recommended. By using the same two sites for cannulation there are reports of less risk of complications and less pain for the patient. However, button-hole cannulation can be difficult for the dialysis nurse, and failing cannulations can damage the AV fistula and increase patient discomfort. The investigators therefore will test whether a simple marking on the skin of the direction and angle of cannulation used in each specific patient could improve the probability of a successful and painfree cannulation.
Interventions
Mark direction and angle for cannulation with a pencil on the skin
Standard practice; i.e. no marks on skin to help find correct direction and angle for introducing needles

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of successful cannulations | 8 weeks | A successful cannulation is defined as being able to insert a blunt needle in both canals at the first attempt. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difficulty of cannulation | 8 weeks | Nurse and patients describe on a Verbal Rating Scale (1-6) how difficult the cannulation was experienced. All dialysis sessions are scored. |
| Fear of cannulation | 8 weeks | Patients describe on a Verbal Rating Scale (0-10) how strongly they fear the cannulation. Assessed once a week. |
| Pain at cannulation | 8 weeks | Patients describe on a VAS scale (0-10) how painful the cannulation was experienced. Assessed once a week. |
