“…Six studies [16,26,33,42,44,51] examined outcomes and costs of a variety of diagnostic tools (e.g., positron-emission tomography vs computed tomography) while four studies [14,23,38,41] related to cervical cancer compared human papilloma virus (HPV) test versus cytology as potential instruments to detect new lesions. Four studies [25,30,34,49] compared costs and health gains arising from a surveillance program versus a 'do nothing' strategy; 11 studies examined traditional hospital-based followup programs in comparison with programs led by other healthcare professionals (i.e., in eight cases [20,31,35,36,43,46,48,52] the nurse and in three [17,19,28] the family physician). One study [15] compared a mobile-app follow-up versus traditional in-person consultations and another one [24] described two programs with (and without) an educational session.…”
