Expanding social health protection in Cambodia: An assessment of the current coverage potential and gaps,and social equity considerations

The Royal Government of Cambodia recently launched its National Social Protection Policy framework to strengthen and expand social security and assistance. To inform social health protection policy, we examine socio-economic survey data and administrative coverage data to assess the coverage potential of existing coverage mechanisms and current gaps; and compare equitable contribution rates. Over 53 per cent of the population currently has no social health protection coverage mechanism, and about 16 per cent of the population who do have access to a mechanism are not yet enrolled. Current expansion efforts focus on the formal employee scheme, primarily benefiting individuals from higher income households. In addition, recent coverage expansion to some informal workers leaves significant gaps, particularly among the informal sector. We find out-of-pocket health care expenditure to be an excessive share of income among lower wealth quintile individuals and conclude they are financially vulnerable. Finally, we illustrate that an equitable approach to individual, monthly health care contributions among the lower three quintiles has a severely limited potential for revenue generation, and collection costs could exceed the amount collected. Therefore, we recommend that vulnerable groups should be exempted from contribution payments as social health protection is expanded.     

A multi-objective coordinate-exchange two-phase local search algorithm for multi-stratum experiments

A multi-stratum design is a useful tool for industrial experimentation, where factors that have levels which are harder to set than others, due to time or cost constraints, are frequently included. The number of different levels of hardness to set defines the number of strata that should be used. The simplest case is the split-plot design, which includes two strata and two sets of factors defined by their level of hardness-to-set. In this paper, we propose a novel computational algorithm which can be used to construct optimal multi-stratum designs for any number of strata and up to six optimality criteria simultaneously. Our algorithm allows the study of the entire Pareto front of the optimization problem and the selection of the designs representing the desired trade-off between the competing objectives. We apply our algorithm to several real case scenarios and we show that the efficiencies of the designs obtained present experimenters with several good options according to their objectives.     

Decision time: Cost estimations and policy implications to advance Universal Health Coverage in Cambodia

Cambodia aims to expand social health protection to move toward Universal Health Coverage. We developed a modeling tool to facilitate the simple, interactive estimation of cost and coverage for three policy alternatives, enabling decision-makers to simultaneously adjust for scenario options currently under consideration. Assuming the adoption of all scenario options, the projected cost of expanding social health protection to all is US$42 million, to vulnerable individuals is US$32.1 million, and to uncovered 1st–3rd wealth quintile people is US$30.4 million. These policy alternatives are projected to increase population coverage to 100%, 89.1%, and 92.5% by 2025, respectively. The results have multiple policy implications. First, given the similar costs and coverage estimates for the targeted approaches, and other considerations, expansion to the 1st–3rd wealth quintiles is recommended. Second, the model quantifies the potential impacts for policy changes relating to each scenario option. The inclusion of dependents under the contributory schemes significantly shifts costs; reversing the policy of non-payment for priority public health services increases public health facility revenue; and, alignment of reimbursement rates leverages demand-side financing which can increase value for money. Finally, the cost estimates provide a basis for economic planning. Revenue raising options include increasing the contribution ceiling for the private employees’ scheme and the progressive adoption of strategic purchasing.
