A situational and stakeholder analysis of health technology assessment in Zimbabwe.

OBJECTIVES: Systematic priority setting is necessary for achieving high-quality healthcare using limited resources in low- and middle-income countries. Health technology assessment (HTA) is a tool that can be used for systematic priority setting. The objective of this study was to conduct a stakeholder and situational analysis of HTA in Zimbabwe. METHODS: We identified and analyzed stakeholders using the International Decision Support Initiative checklist. The identified stakeholders were invited to an HTA workshop convened at the University of Zimbabwe. We used an existing HTA situational analysis questionnaire to ask for participants' views on the need, demand, and supply of HTA. A follow-up survey was done among representatives of stakeholder organizations that failed to attend the workshop. We reviewed two health policy documents relevant to the HTA. Qualitative data from the survey and document review were analyzed using thematic analysis. RESULTS: Forty-eight organizations were identified as stakeholders for HTA in Zimbabwe. A total of 41 respondents from these stakeholder organizations participated in the survey. Respondents highlighted that the HTA was needed for transparent decision making. The demand for HTA-related evidence was high except for the health economic and ethics dimensions, perhaps reflecting a lack of awareness. Ministry of Health was listed as a major supplier of HTA data. CONCLUSIONS: There is no formal HTA agency in the Zimbabwe healthcare system. Various institutions make decisions on prioritization, procurement, and coverage of health services. The activities undertaken by these organizations provide context for the institutionalization of HTA in Zimbabwe.

Consumers' access to information about medicine prices and availability as an enabler of last mile medicine access: A scoping review.

Information about where medicines are in stock and how much they cost facilitates consumers' timely access to affordable medicines by enabling price comparisons and the identification of stockists. Our aims were to: (1) Review how consumer access to price and availability information is engaged within the Medicine Access discourse and (2) identify factors associated with the existence of interventions that provide consumers with medicine availability and price information. We conducted two scoping reviews. We reviewed 26 medicine access and pharmaceutical system strengthening frameworks to assess how they conceptualise information access. We then reviewed four interventions that provide consumers with availability and price information to identify the factors associated with these interventions' existence. We found that in the medical access discourse, information is mainly cast as helpful to entities that ensure medicine access for populations. Information as an enabler of medicine procurement for consumers/households is less emphasised. We then identified the following eight factors that facilitate consumer access to reliable medicine price and availability information: the recognition of a medicine access problem that can be mitigated by consumer access to information; cross-sectoral collaboration; the willingness of medicine sellers to disclose their inventory information; having information quality control measures; appropriate incentives for intervention adoption; enabling legal environments; systems of pooling information; and access to digital information technology infrastructure. We recommend that more theoretical and implementation attention ought to be directed at how medicine price and medicine availability information can empower individual consumers to make sound purchasing decisions.

Progress on the elimination of viral hepatitis in Zimbabwe: A review of the policies, strategies and challenges.

Very few low-income countries have developed national plans to achieve the viral hepatitis elimination targets set in the World Health Organization (WHO) strategy. We reviewed the policy environment, strategies and challenges on the fight against viral hepatitis in Zimbabwe. The review focussed on the Ministry of Health and Child Care (MoHCC) policy documents, strategic plans and reports. We performed key informant interviews to enhance evidence generated from the document review. Twelve documents were reviewed and interviews with 10 key informants were completed. The MoHCC established a technical working group to work towards elimination of viral hepatitis. The technical working group drafted a strategic plan for elimination of viral hepatitis; however, it is still awaiting implementation. Key strategies that are working well include screening of donated blood for transfusion, safe injection practices and hepatitis B virus (HBV) three-dose vaccination. Current challenges in the drive towards elimination of viral hepatitis include poor to non-existent surveillance systems, lack of epidemiological data, absence of the HBV vaccine birth dose and lack of systematic screening and treatment services for viral hepatitis. In conclusion, despite political will demonstrated towards achieving viral hepatitis elimination, substantial investment and work are required to implement the strategic plan and realize significant success.

Impact of acute, oral ingestion of hypoxoside from African potato on hepatic and renal function tests in HIV infected patients on combination antiretroviral therapy.

OBJECTIVES: African potato (hypoxis hemerocallidea) is used against HIV to enhance immune-function, although no studies have evaluated its use in HIV infected individuals on combination antiretroviral therapy. The study aimed to evaluate the acute effects of orally administered hypoxoside, a constituent of African potato, on the hepatic and renal function in HIV infected individuals on tenofovir disoproxil fumarate/ lamivudine/ efavirenz regimen. METHODS: This was an open-label, two-period, fixed-sequence, pre-post test study, pilot design. Ethical approval was obtained from Medical Research Council of Zimbabwe (MRCZ A/2045) and Medicines Control Authority of Zimbabwe (MCAZ CT134/2016). Blood samples were collected before and after administration of African potato tablets. Tablets were administered orally once daily at 15mg/ kg hypoxoside for 10 days. Hepatic function tests (ALT, AST, ALP, GGT, albumin, total/ direct bilirubin); renal function tests (eGFR, blood urea nitrogen, creatinine), serum electrolytes (sodium, potassium, chloride) were assayed. STATA was used for statistical analysis. RESULTS: Twenty-six participants were enrolled (85% female). Median age (range) was 43 (28-52) years. Most had overweight Body Mass Index (46%) and were married (54%). No statistical difference was noted during hypoxoside for AST/ ALT/ ALP/ GGT/ albumin/ bilirubin. There were no changes in creatinine/ eGFR/ electrolytes. A mean significant increase in total protein (p=0.04) and decrease in blood urea nitrogen (p=0.04) were noted. CONCLUSION: Short-term exposure to hypoxoside from African potato appeared safe and was not associated with clinically significant changes in hepatic, renal function tests/electrolytes. There is further need to evaluate extent of systemic exposure during long-term use in a larger population.

African potato (Hypoxis hemerocallidea): a systematic review of its chemistry, pharmacology and ethno medicinal properties.

BACKGROUND: African Potato (hypoxis hemerocallidea), is used for enhancing immune system in Southern Africa. It is among the plants of intense commercial and scientific interest; hence, the aim of this study was to describe its chemistry and pharmacology. METHODS: PubMed, Cochrane Controlled Trials Register (CENTRAL) and Google Scholar were searched independently for relevant literature. The last search occurred in October 2018. Other research material was obtained from Google. The following search terms were used, but not limited to: "African Potato", "hypoxis", "hemerocallidea", "rooperol." Articles that were explaining the chemistry and pharmacology of hypoxis hemerocallidea were included. RESULTS: Thirty articles from PubMed, Cochrane and Google Scholar were eligible. Three webpages were included from Google. Results showed that the tuberous rootstock (corm) of African Potato is used traditionally to treat wasting diseases, testicular tumours, insanity, barrenness, impotency, bad dreams, intestinal parasites, urinary infection, cardiac disease and enhancing immunity. The plant contains hypoxoside, which is converted rapidly to a potent antioxidant, rooperol in the gut. The corm contains sterols, sterol glycosides, stanols, terpenoids, saponins, cardiac glycosides, tannins and reducing sugars. A dose of 15 mg/kg/day of hypoxoside is reportedly therapeutic. Preclinical studies of African Potato have shown immunomodulation, antioxidant, antinociceptive, hypoglycaemic, anti-inflammatory, anticonvulsant, antibacterial, uterolytic, antimotility, spasmolytic and anticholinergic effects. The common side effects of African Potato are nausea and vomiting, which subside over time. In vitro, African Potato demonstrated inhibitory effects on CYP1A2, 2C9, 2D6, 3A4, 3A5, CYP19-metabolism and induction of P-glycoprotein. In vivo, it did not alter the pharmacokinetics of efavirenz or lopinavir/ritonavir. CONCLUSION: African Potato is mainly used as an immunostimulant. The exact mechanisms of action for all the pharmacological actions are unknown. More research is required to substantiate claims regarding beneficial effects. There are many research gaps that require investigation including pharmacokinetic interactions with conventional drugs, especially those used in HIV/AIDS.
