Variations in chemoprophylaxis for meningococcal disease: a retrospective case note review, analysis of routine prescribing data and questionnaire of general practitioners

BACKGROUND: Invasive meningococcal disease is a significant cause of mortality and morbidity in the UK. Administration of chemoprophylaxis to close contacts reduces the risk of a secondary case. However, unnecessary chemoprophylaxis may be associated with adverse reactions, increased antibiotic resistance and removal of organisms, such as Neisseria lactamica, which help to protect against meningococcal disease. Limited evidence exists to suggest that overuse of chemoprophylaxis may occur. This study aimed to evaluate prescribing of chemoprophylaxis for contacts of meningococcal disease by general practitioners and hospital staff. METHODS: Retrospective case note review of cases of meningococcal disease was conducted in one health district from 1st September 1997 to 31st August 1999. Routine hospital and general practitioner prescribing data was searched for chemoprophylactic prescriptions of rifampicin and ciprofloxacin. A questionnaire of general practitioners was undertaken to obtain more detailed information. RESULTS: Prescribing by hospital doctors was in line with recommendations by the Consultant for Communicable Disease Control. General practitioners prescribed 118% more chemoprophylaxis than was recommended. Size of practice and training status did not affect the level of additional prescribing, but there were significant differences by geographical area. The highest levels of prescribing occurred in areas with high disease rates and associated publicity. However, some true close contacts did not appear to receive prophylaxis. CONCLUSIONS: Receipt of chemoprophylaxis is affected by a series of patient, doctor and community interactions. High publicity appears to increase demand for prophylaxis. Some true contacts do not receive appropriate chemoprophylaxis and are left at an unnecessarily increased risk

Prophylactic antibiotics for the prevention of cellulitis

Background: Cellulitis of the lower leg accounts for 2-3% of hospital admissions (Cox et al, 1998), with an average length of in-patient stay of nine days. Studies have reported that up to half of these patients suffer further episodes (Cox et al, 1998; Dupuy et al, 1999). Reducing the recurrence of cellulitis could therefore have a significant impact on both patient morbidity and NHS costs. Aims: To assess whether prophylactic antibiotics prescribed after an episode of cellulitis of the leg results in fewer subsequent attacks and reduced health service costs (PATCH prophylactic antibiotics for the treatment of cellulitis at home). Methods: This article describes two related studies in which participants are randomised to receive either 12 months of prophylaxis (PATCH I) or six months of prophylaxis (PATCH II). The PATCH I study recruits only patients with recurrent disease defined as two or more episodes of cellulitis in the last three years. PATCH II has more open criteria and includes patients with a first episode of cellulitis and also participants with recurrent disease. It is expected that 260 patients will be recruited into PATCH I and 400 patients into PATCH II.
