The economic impact of individually packaged screws

BackgroundTrends in orthopaedic surgery have seen a migration towards using individually packaged screws (IPS). The manufacturers claim IPS improves sterility, traceability, and avoids the effects of repeated sterilisation. In recent times there has been increasing pressure on the NHS to be more cost-efficient. Challenging decisions must be made to make cost-efficient choices without comprising the quality of care provided.AimThis study investigates the cost-benefit of IPS compared to the conventional screw rack stored screws (SRSS).MethodsA single-centred observational study was carried out in a district general hospital between February and March 2013. One-hundred and forty-seven screws were requested intra-operatively and the screw acquisition time was measured with a digital handheld timer. Screw acquisition time was defined as the time taken from the initial verbal request to when the screw was mounted ready for use. The screws were categorised into two groups: SRSS and IPS.ResultsThe mean screw acquisition time for the SRSS group (n = 94) was 6.6 s (S.D ± 2.5). The mean screw acquisition time for the IPS group (n = 53) was 102.1 s (S.D ± 25.7). The mean difference between SRSS and IPS was 96 s (95%CI 90.3–100.8; p < 0.001).ConclusionOur study suggests that the use of IPS significantly (p < 0.001) increases the operation duration and costs compared to SRSS. Based on ankle ORIF procedures alone, the use of IPS could potentially increase department spending by approximately £76,680 per year.
