Prescribing patterns in adult patients with meningitis in internal medicine wards, Dr George Mukhari Hospital

Abstract

Background Information regarding disease epidemiology, treatment options and emerging infections and resistance constantly challenge the knowledge of the health care practitioner. Antibiotic prescribing patterns was identified by the Dr George Mukhari hospital antibiotics committee as an area of concern. Due to this concern it was decided to investigate the prescribing patterns in adult patients with meningitis admitted to the internal medicine wards at Dr George Mukhari hospital. Objectives To determine the current antimicrobial prescribing patterns in adult patients diagnosed with meningitis, to record the causative organisms and sensitivity patterns, to record the outcom e, cost and length of treatment. Method Patient and prescriptions data were recorded prospectively on specially designed data sheets from five internal medicine wards for four months (May to August 2008). Patients were followed until discharged. Results Sixty-six patients were enrolled; 41 recovered, 22 died, 2 refused treatment and 1 absconded. Ceftriaxone was prescribed the most frequently and was administered to 58 patients; four patients with confirmed cryptococcal meningitis received amphotericin B IVI, three patients were started on iv Rifafour® for suspected tuberculosis meningitis and one was started on cefuroxime. Specimens from only 22 patients were sent for culture and sensitivity tests; ten were positive for yeast-like organisms, three for S pneumoniae and one for N meningitides and tuberculosis respectively. The average duration of treatment of patients with meningitis was 9.2days. The total cost of antiinfectives used for treatment of meningitis amounted to R111, 292.53 and the average cost per patient was R1 686.25. The cost of all medicines prescribed for the 66 patients amounted to R116, 490.43. Conclusion Ceftriaxone was used frequently as empiric therapy. Specimens for culture and sensitivity were not sent routinely. Therefore it was difficult to monitor and observe any resistance patterns and to contain cost of treatment.
