Quality assessment of medicines in selected resource-limited primary healthcare facilities using low- to medium-cost field testing digital technologies.

BACKGROUND

Digital technologies can assess the quality of medicines in resource-challenged health facilities in a timely manner and ensure effective healthcare.

OBJECTIVES

This study assessed the quality of some non-communicable disease medicines, antimalarials, antibiotics, non-steroidal anti-inflammatory drugs and hematinics in selected healthcare facilities as part of their (potential) participation in a digital pharmaceutical supply chain management system (Med4All).

METHODS

All the sampled medicines were screened using TruScan analyzer and GPHF-minilab, that is low-medium field technologies. The quality of a representative subset of the medicines (∼11%) was determined using pharmacopoeia gold standard methods.

RESULTS

About 75% of the medicines were manufactured in Ghana, and 16% were imported from India, with the Ghana Food and Drugs Authority registering 72% of the medicines. There was over 90% availability of medicines in health facilities from the middle and southern sectors, while the northern sector had around 64%. Approximately 87% and 88% of the medicines passed TruScan™ Raman and GPHF-minilab analysis, respectively. There was no significant difference between the two screening methods for assessing the quality of the medicines ( > 0.05). Of the 21 medicine samples, 5 (∼24%) failed, and 16 (76%) passed the pharmacopoeia test. The failed medicines were diclofenac, azithromycin and glibenclamide. Compared to the pharmacopoeia method, the performance of the TruScan™ Raman analyzer and the GPHF-minilab technologies were 71% and 63%, respectively.

CONCLUSION

The study provides insights into the quality of medicines in resource-limited primary healthcare facilities.
