In Lao PDR, the National Malaria Control Program (NMCP) evaluates bednet coverage, often at the village level, using a coverage target of one net per 2.5 (or fewer) persons in a given population. However, in villages that meet the target, not all households necessarily meet the target or utilize all available bednets. This study explored households that fell short of the target and household utilization of bednets in villages that met the target of bednet coverage set by the NMCP. The person per net ratio (PPNR), which is defined as the population divided by the number of available bednets in a household/village, was used to determine whether a household/village met the NMCP target. Using a household survey, we collected and analyzed the data of 635 households in 17 villages in Xepon district in 2012. Households that fell short of the target (households with a PPNR of > 2.5 or no bednet) existed in every village. The proportion of these households differed greatly among the villages, ranging from 3.4-50%, with some households falling far short. Of the 635 households, 275 (43.5%) had at least one bednet that was not being used on the night preceding the survey and 131 (20.6%) had at least two. In conclusion, in villages that met the NMCP target, a considerable number of households fell short of the target, and the available bednets were not fully utilized in many of the surveyed households.
在老挝人民民主共和国，国家疟疾控制规划（NMCP）通常在村级层面评估蚊帐覆盖率，其给定人群的覆盖率目标是每2.5人（或更少）拥有一顶蚊帐。然而，在达到目标的村庄中，并非所有家庭都必然达到目标或使用了所有可用蚊帐。本研究探讨了未达目标的家庭以及在达到NMCP蚊帐覆盖率目标的村庄中家庭对蚊帐的使用情况。每蚊帐人数比（PPNR）定义为家庭/村庄中的人口数除以可用蚊帐数，用于确定家庭/村庄是否达到NMCP目标。通过家庭调查，我们收集并分析了2012年色邦县17个村庄635户家庭的数据。每个村庄都存在未达目标的家庭（PPNR大于2.5或没有蚊帐的家庭）。这些家庭的比例在不同村庄之间差异很大，范围从3.4%至50%，有些家庭远远未达目标。在635户家庭中，275户（43.5%）在调查前一晚至少有一顶蚊帐未被使用，131户（20.6%）至少有两顶未被使用。总之，在达到NMCP目标的村庄中，相当数量的家庭未达目标，并且在许多接受调查的家庭中，可用蚊帐未得到充分利用。
