Following recent concerns about patients' inability to book appointments in advance, this study examined the relationship between the proportion of GP appointments reserved for same-day booking, and patient satisfaction with appointment systems. In a survey of 12,825 patients in 47 practices, it was found that a 10% increase in the proportion of same-day appointments was associated with an 8% reduction in the proportion of patients satisfied. Practices should be wary of increasing the level of same-day appointments to meet access targets.
