Patients' understanding of prescription instructions in a semi-urban setting in Cameroon.
OBJECTIVE
This cross-sectional study investigates the factors associated with patient comprehension of frequently used prescription patterns and explores patients' preferences for the various methods.


METHODS
We interviewed two hundred and four consenting patients selected consecutively from the waiting rooms of the St. Elizabeth Catholic Hospital-Shisong in the north west region of Cameroon. We recorded socio-demographic data and their understanding and preference for four prescription modalities: pictograms, written out, symbols and Latin abbreviations. We studied the relationship between these variables in a logistic multivariate analysis.


RESULTS
Understanding was best with symbols (89.7%) and worst when Latin abbreviations (26.9%) were used. Higher levels of education were associated with better understanding of Latin abbreviations (OR 18.87; 95% CI 2.44-142.86), written out prescriptions (OR 58.82; 95% CI 23.25-333.33), symbols (OR 1.47; 95% CI 4.25-50.00) and pictograms (OR 52.63; 92% CI 1.85-142.86) after controlling for confounding. Participants mostly preferred pictograms (40.7%) and written-out prescriptions (30.9%).


CONCLUSIONS
Latin abbreviations were the most difficult to understand and should no longer be used. Symbols are more easily understood.


CONCLUSIONS
Latin abbreviations should be discouraged. Symbols are better, especially for patients with low levels of education. Prescribing using pictograms and plain text may facilitate understanding in this setting.
