Summary of the Health Equity and Financial Protection Report – Zambia

Core Content

This report provides an analysis of health equity and financial protection in Zambia, focusing on disparities in health outcomes, health care utilization, and the financial burden of health spending. It uses data from various household surveys and analyzes the impact of different financing mechanisms on the poor and the rich.

Main Topics and Findings

1. Health System Overview

• Policy Goals: The Government of Zambia has prioritized equity and financial protection in its health sector reforms, aiming to provide accessible, cost-effective, and quality healthcare.
• Health Financing: In 2009, Zambia spent 6.2% of its GDP on health, with government funding accounting for 59.5% of total health expenditures. Out-of-pocket payments make up 27.2% of total health spending, while other private sources contribute the remaining.
• Decentralization: Zambia implemented a major decentralization reform in the 1990s, which was later reversed in 2005 with the re-centralization of health management. The public sector serves the majority of the population, but there is a significant lack of human resources in rural areas.
• Payment Mechanisms: The health system relies on a mix of government funding, donor support, and out-of-pocket payments. Risk-pooling through insurance is limited, with no formal social health insurance system in place.

2. Inequalities in Health Outcomes

• Child Health: Ill health indicators such as stunting, underweight, and malaria are more concentrated among the poor. Diarrhea shows a slight pro-rich trend, though not statistically significant. Infant and under-five mortality rates are not statistically significantly different across wealth groups.
• Adult Health: Conditions like tuberculosis and arthritis are more prevalent among the poor. HIV prevalence and obesity among non-pregnant women are more common among the better-off. Non-traffic accidents, angina, depression, and diabetes show mixed results, with only a few being statistically significant.
• Health Behaviors: Smoking and insufficient physical activity are more common among the poor, while excessive drinking and concurrent sexual partnerships are more prevalent among the wealthy. Mosquito net use is higher among the better-off, though not statistically significant.

3. Inequalities in Health Care Utilization

• Maternal and Child Health (MCH): Access to MCH interventions is more concentrated among the better-off. Antenatal care, skilled birth attendance, and contraceptive prevalence are higher for wealthier populations. However, some services like treatment for diarrhea show a slight pro-poor trend.
• Adult Preventive and Curative Care: Utilization of adult preventive services is not significantly different across wealth quintiles. For curative care, there is no clear pattern, but some services are more accessible to the wealthy.

4. Financial Protection in Health

• Out-of-Pocket Payments: Only about 5% of households spend more than 10% of total consumption on out-of-pocket health payments, and 2% spend more than 25%. Using nonfood consumption, 32.5% of households spend over 10%, and 23.7% over 40%.
• Catastrophic Spending: Catastrophic out-of-pocket payments are highly concentrated among the poor, especially at higher thresholds. These payments contribute to a slight increase in the poverty rate (0.4% using the US$2.00/day measure and 0.2% using the US$1.25/day measure).
• Impoverishing Effect: The impoverishing effect of health spending is minimal, with an increase in the depth of poverty of less than 1%.

5. Progressivity of Health Finance

• Overall Progressivity: Health financing in Zambia is fairly progressive, as the better-off spend a larger share of their consumption on health care.
• Sources of Funding: General taxation (42%) and contributions from private employers (9%) are the main sources of progressivity. Pre-payment mechanisms contribute slightly, but remain limited.
• Out-of-Pocket Payments: These account for 47% of total health financing and are proportional to income, with only slight and non-statistically significant evidence of progressivity.

Key Information

• Data Sources: The report uses data from the 2007 Zambia Demographic and Health Survey (DHS), the 2003 Zambia World Health Survey (WHS), and the 2003 Zambia National Health Accounts (NHA).
• Methodology: All analyses are conducted using the health modules of the ADePT software.
• Health Workforce: Zambia has a severe shortage of health professionals, particularly in rural areas, with only 0.93 clinical health workers per 1,000 population in 2009, far below the WHO recommendation.
• Healthcare Access: Despite government efforts to improve access, the poor still face challenges in accessing healthcare services, especially in rural areas.

Conclusion

The report highlights that ill health and risky behaviors are more concentrated among the poor in Zambia, but the financial burden of health care is not as severe as might be expected. While the health financing system is fairly progressive, out-of-pocket payments remain a significant portion of health spending and are disproportionately borne by the poor. The lack of a formal social health insurance system and limited risk-pooling mechanisms suggest that financial protection is still a challenge, particularly for vulnerable populations.
