RESUMEN
BACKGROUND: This study was designed to determine the characteristics of medical negligence claims in rhinology. In 2010-2011 the National Health Service (NHS) litigation bill surpassed 1 billion Great British Pounds (GBP; 1.52 billion U.S. dollars [US$]). Systematic analysis of malpractice complaints allows for the identification of errors and can thereby improve patient safety and reduce the burden of litigation claims on health services. METHODS: Claims relating to ear, nose, and throat between 1995 and 2010 were obtained from the NHS Litigation Authority and were analyzed. RESULTS: The series contains 65 closed claims that resulted in payment totaling 3.1 million GBP (US$4.7 million). Fifty claims were related to surgical complications. Functional endoscopic sinus surgery and septoplasty were the procedures most commonly associated with successful claims. There were 11 cases of orbital injury including 6 cases of visual loss and 5 cases of diplopia. The most common cause of a claim was failure to recognize the complication or manage it appropriately. Lack of informed consent was claimed in eight cases. Other claims arose because of errors in outpatient procedures (two), diagnosis (six), delayed surgery (one), and errors in medical management (three). CONCLUSION: This is the first study to report the outcomes of negligence claims in rhinology in the United Kingdom. Claims in rhinology are associated with a high success rate. Steps that can be taken to reduce litigation include careful patient workup and ensuring adequate informed consent. Where there is a suspicion of orbital damage early recognition and intervention is needed to reduce long-term injury to the patient.

Intraocular lens implantation after opacified natural lens removal is the primary treatment for cataracts in developed countries. Cataract surgery is generally considered safe, but entails significant risks in countries where sophisticated sterile operating theaters are not widely available. Post-operative infection (endophthalmitis) is a potential blinding complication. Infection often results from bacterial colonization of the new lens implant and subsequent antibiotic-tolerant biofilm formation. To combat this risk, we developed a polymeric hydrogel system that can deliver effective levels of antibiotic over an extended period of time within the globe of the eye. Norfloxacin antibiotic was loaded into cross-linked poly(2-hydroxyethyl methacrylate) (pHEMA) gels, which were subsequently surface-modified with octadecyl isocyanate to produce a hydrophobic rate-limiting barrier controlling norfloxacin release. Octadecyl surface modification was characterized using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). A 15-min modification leads to a uniform surface coating and near zero order release of norfloxacin from the matrix. Norfloxacin released from coated pHEMA kills Staphylococcus epidermidis in suspension and on a simulated medical implant surface. With these data, we demonstrate a new and effective system for sustained drug release from a hydrogel matrix with specific application for intraocular lens surgery.
