The demand for outpatient hospital appointments has risen steadily over recent years, almost doubling since 2008; now standing at 120 million appointments per year. Initiatives to reduce unnecessary appointments are a key area of interest, as they can be an effective way of both improving patient care and satisfaction, as well as reducing NHS costs. Patient Initiated Follow-Up (PIFU) provides an alternative to traditional hospital instigated follow-up, by which patients have autonomy in their future care, allowing them to make appointments based on their own perception of need. PIFU has proved successful when implemented in Rheumatology, Inflammatory Bowel Disease and Oncology, with trends towards reduced burden on outpatient appointments, improved patient satisfaction and lower costs. To-date, the use of PIFU in women's health has been limited to gynaecological oncology, where observations include high patient satisfaction and fewer appointments than traditional follow-up. This study aims to undertake a systematic review of the literature relating to PIFU in Obstetrics and Gynaecology in order to identify evidence-based indications for PIFU in the specialty, as well as form a foundation for a subsequent service evaluation.
