Prescription Patterns and Patient Care Practices in Two Tertiary Hospitals in South-South Nigeria

Inappropriate use of medicines still characterize all levels of healthcare, with important public health implications. Available evidence indicate that irrational use of medicines can lead to poor therapeutic outcomes, adverse drug reactions, and thus increase morbidity and mortality rates. This study assessed the prescription pattern, patient and health care facility indicators in two tertiary health facilities in Nigeria.

A cross-sectional survey of 1800 prescriptions and 600 patients' encounters was conducted at the General Outpatient Departments of the University of Benin and Delta State University Teaching Hospitals using the WHO drug use indicators. Data from 12-month prescription sheets as well as patient interviews were entered into standard indicator forms and analyzed according to WHO guidelines.

Overall, the average number of drugs per encounter was 2.8 ± 1.6. The percentage of generic prescription was 49.6%, while percentage of encounters with antibiotics, antimalarial and injections were 27.4%, 23.2% and 12.4% respectively. Prescription of medicines listed in the Essential Medicines List was 66.6%, even though no copy was available at the consulting rooms. Average consulting and dispensing time were 15.3 minutes and 136 seconds respectively. Percentage of medicines actually dispensed was 86.2% while 98.7% of medicines were adequately labelled.

Gaps still exist in the rational use of medicines in Nigeria. There needs to be sustained interventional schemes with capacity for monitoring and evaluation to detect inappropriate drug use patterns and prevent the undesirable consequences of irrational use of medicines.
