The knowledge and attitudes of psychiatrists towards antipsychotic long-acting injections in Nigeria

Antipsychotic long-acting injections (LAIs) reduce covert nonadherence with medication in the clinical management of psychotic disorders. However, they are variably utilised by clinicians, especially in the long term. Factors including poor knowledge, stigma and perceived coercion can all adversely influence LAI utilisation. Previous research has emanated almost exclusively from developed countries. This study explores the knowledge and attitudes of psychiatrists and trainees in Nigeria towards LAIs. A cross-sectional study was undertaken among mental health professionals in Nigeria using a pre-existing questionnaire. Participant psychiatrists (n = 128) expressed positive attitudes towards LAIs. Their knowledge concerning LAIs and its side effects was fair. The participants reported that nearly half (41.7%) of their patients with a psychotic illness were on LAIs. Those who reported a high prescribing rate for LAIs (>40%) were more likely to endorse more positive ‘patient-centred attitudes’ (p < 0.04). In contrast to previous reports, psychiatrists reported that patients were less likely to feel ashamed when on LAIs, though most endorsed the statement that force was required during LAI administration. The desirability of treatment by injections differs in Africa in comparison to Western cultures, possibly due to the increased potency that injections are perceived to have. This is perhaps evidenced by high rates reported for use of LAIs. Nigerian psychiatrists had positive attitudes to LAIs but their knowledge, particularly regarding side effects, was fair and needs to be improved. Providing information to patients prior to antipsychotic treatment may enhance informed consent in a country where medical paternalism is still relatively strong. © 2012, SAGE Publications.
