Waiting is common in health care, delays intervention, and has negative effects on satisfaction with services.
To evaluate effects of a modified walk-in system, where patients were invited consecutively from the waiting list to attend the clinic on a walk-in basis, on waiting times, services, and work environment.
In all, 1286 consecutive patients in need of shoe insoles were randomized to waiting lists for modified walk-in ( n = 655) or a scheduled appointment ( n = 631). Seven staff members also participated.
The median indirect waiting time to first appointment was 40 days shorter for modified walk-in (135 days) than for scheduled appointment (175 days; p < 0.001); 17% of those randomized to modified walk-in did not attend the clinic compared to 6% for scheduled appointment ( p < 0.001). Mean direct waiting time in the waiting room was 9.9 min longer for modified walk-in than for scheduled appointment ( p < 0.001). Patients attending modified walk-in or a scheduled appointment reported similar levels of satisfaction with services. Staff reported more support from co-workers with modified walk-in than with scheduled appointment ( p = 0.041).
