Increased post-tonsillectomy secondary haemorrhage with disposable instruments: an audit cycle.
The objective of the audit was to examine the increased morbidity associated with elective tonsillectomy with single-use instruments in a district general hospital in England. Retrospective audit of consecutive case notes of 145 patients who underwent tonsillectomy in a 6-week period after the introduction of single-use instruments was carried out. The main outcome measure was incidence of secondary haemorrhage. In total, 9.5% of patients required re-admission indicated by secondary haemorrhage, 4% required emergency surgery and 43% of the total group had haemostasis achieved with ties. None of these was re-admitted. Out of the total group, 57% had haemostasis achieved with single-use bipolar forceps; 16.8% of these patients were re-admitted, with 7% of this group requiring emergency surgery to control the haemorrhage. Animal tissue experiments and design analysis of the single-use bipolar diathermy highlighted the deficiencies of the initial single-use bipolar diathermy. This was replaced by a new design of single-use diathermy forceps. A second audit was performed which revealed a significant reduction in postoperative morbidity. Complications associated with the introduction of new instruments can be identified by repeated audit cycles.
