Understanding the decision making process of selection of medicines in the private sector in South Africa - lessons for low-middle income countries.

BACKGROUND

The affordability of essential medicines is a challenge in achieving Universal Health Coverage (UHC). One of The Lancet Commission's recommendations on financing of essential medicines is to ensure governments and national health systems include essential medicines in the benefit packages provided by public and private healthcare sectors. Currently in South Africa (SA), there is a dearth of information on the processes for medicines selection for private sector medical scheme formularies. This study aimed to improve the understanding of how formulary managers of selected medical schemes made decisions for the selection of medicines for their formularies. This paper described their opinions obtained from in-depth interviews.

METHODS

Qualitative in-depth interviews were conducted with 10 individuals from 7 private sector medical schemes and administrators in SA. All participants interviewed were involved in formulary development and management. Interviews were conducted from June 2013 - January 2015. Interviews were guided by a discussion guide and audio recorded. Recorded interviews were transcribed verbatim. Transcripts were coded by the first author, corroborated by the second author, reconciled, and imported into NVIVO for data analysis.

RESULTS

Schemes and administrators had similar formulary decision making and management committees in place (viz. Clinical and Therapeutics committees). The process of and criteria for medicines selection and evidence based review of formularies were also similar. Selection of medicines was inherent in the formulary review process. Medicine price was important in the decision taken to list medicines. Most schemes expressed a difficulty with lack of information to support pharmacoeconomic evaluations of medicines for inclusion on the formulary. This together with the basic monitoring of use of medicines by patients for most schemes left room for improvement in the decision making process for those schemes.

CONCLUSIONS

This is one of the first studies in SA describing interviews with private sector medical scheme Formulary managers. It contributes to an increased understanding of how decisions are taken to include/exclude medicines on private sector medical scheme formularies. It provides insight into the medicine selection and review processes, including processes on monitoring and evaluation of medicines use by the private sector which serve as lessons for Low-Middle income countries moving towards UHC.
