A demographic study to profile non-attenders at a gynaecology outpatient clinic

Missed outpatient appointments result in the inefficient utilisation of resources and have secondary effects on the health of the non-attenders, as well as on other patients who have to wait longer for their appointments. The first part of the study involved retrospective analysis of trends of non-attendance based on a computerised database of all gynaecology appointments over 12 months. The second comprised a prospective case-control study in which women who missed their gynaecology outpatient appointments (index cases) over 2 months were compared with patients who attended the same clinics matched for indication for referral (control cases). The overall non-attendance rate over 12 months was 16.1%, of whom 42% were recurrent non-attenders. Data from 105 defaulters were compared with 105 non-defaulters who attended the same clinics. Defaulters were significantly younger, single or separated and were more likely to be 'follow-ups' rather than new cases (all p < 0.05). Longer intervals between the appointment letter and actual appointment date was significantly related to non-attendance (p = 0.01) and there was a trend to a greater degree of smoking and alcohol ingestion in the defaulter group (p = 0.059). Comparison of other variables such as severity of symptoms, parity, source of referral and fluency of English did not reach statistical significance (p > 0.05). This prospective study has demonstrated certain profiles which are common to defaulters and which can be used to develop strategies to minimise non-attendance. Examples include reducing the time interval between sending the appointment letter and actual appointment date and selectively over-booking younger, single women who smoke.
