“…Sixteen studies only included patients with non-urgent problems. [12, 14, 17, 19, 22, 24, 25, 27, 29–31, 34, 35, 37–39] Sixteen studies made use of questionnaires [3, 5, 12, 13, 16–19, 27, 31–33, 36–39], often with multiple choice questions [3, 5, 12, 13, 16, 19, 22, 27, 33, 37, 39] Three studies performed interviews with qualitative methodologies [29, 30, 34]. Others performed interviews without qualitative methods, sometimes by telephone, or by letting the treating physician or triage nurse ask one open question [14, 15, 20–26, 28, 31, 32, 35].…”
