The process-orientated multidisciplinary approach (POMA) clinic is a means of delivering consultantled healthcare from the first outpatient clinic visit through to discharge, bringing together clinical and operational management and resulting in effective resource utilisation and improved patient care. We present the impact of the POMA clinic on the number of cancellations, post-operative clinical incidents (POCI), the post-operative length of stay (PLOS) and the cost-effectiveness of the process on the practice of one consultant surgeon. POMA was the only significant factor in the reduction of cancellations, POCI and PLOS (P = 0.015) on multivariate analysis. POMA has resulted in an overall saving of £285 868.00 (E400 215.00; $508 845.00) calculated using 2005 NHS tariffs. Systems such as POMA can have a major impact on the efficient utilisation of resources, benefiting staff, the department and the patients.
