Pre-post implementation survey of a multicomponent intervention to improve informed consent for caesarean section in Southern Malawi

Abstract

ObjectiveSurgical informed consent is essential prior to caesarean section, but potentially compromised by insufficient communication. We assessed the association between a multicomponent intervention and women’s recollection of information pertaining to informed consent for caesarean section in a low-resource setting, thereby contributing to respectful maternity care.DesignPre-post implementation survey, conducted from January to June 2018, surveying women prior to discharge.SettingRural 150-bed mission hospital in Southern Malawi.ParticipantsA total of 160 postoperative women were included: 80 preimplementation and 80 postimplementation.InterventionBased on observed deficiencies and input from local stakeholders, a multicomponent intervention was developed, consisting of a standardised checklist, wall poster with a six-step guide and on-the-job communication training for health workers.Primary and secondary outcome measuresIndividual components of informed consent were: indication, explanation of procedure, common complications, implications for future pregnancies and verbal enquiry of consent, which were compared preintervention and postintervention using χ2test. Generalised linear models were used to analyse incompleteness scores and recollection of the informed consent process.ResultsThe proportion of women who recollected being informed about procedure-related risks increased from 25/80 to 47/80 (OR 3.13 (95% CI 1.64 to 6.00)). Recollection of an explanation of the procedure changed from 44/80 to 55/80 (OR 1.80 (0.94 to 3.44)), implications for future pregnancy from 25/80 to 47/80 (1.69 (0.89 to 3.20)) and of consent enquiry from 67/80 to 73/80 (OR 2.02 (0.73 to 5.37)). After controlling for other variables, incompleteness scores postintervention were 26% lower (Exp(β)=0.74; 95% CI 0.57 to 0.96). Recollection of common complications increased with 0.25 complications (β=0.25; 95% CI 0.01 to 0.49). Recollection of the correct indication did not differ significantly.ConclusionRecollection of informed consent for caesarean section changed significantly in the postintervention group. Obtaining informed consent for caesarean section is one of the essential components of respectful maternity care.
