Develop methodology to estimate the annual cost of resources used by school sealant programs (SSPs) and demonstrate its use.
We used existing literature and expert opinion to identify SSP cost components and the most appropriate units for their measurement (e.g., per operator) and collection frequency (e.g., per day). For equipment and reusable instruments, costs were sufficiently homogenous across SSPs that we could provide default per unit cost estimates (2016 US$) that SSPs can use in lieu of collecting their own data. We also provide default costs for supply items such that SSPs can estimate total supply costs with program-specific information on sealant material used, as well as number of: sealant stations, operators, service delivery days, children screened/sealed, and number of teeth sealed. For the remaining three categories (labor, mileage, and administrative), costs varied substantially by SSP and required us to develop and pilot collection logs for program-specific data.
The annual cost per sealant station ranged from $584 to $797 depending on program characteristics. For a hypothetical SSP that staffed each of two stations with two operators (hygienist and assistant) compensated at the national rate, hourly labor costs would equal $77.97. Assuming this SSP used disposable instruments, light-cured sealants and delivered sealants (3 per child) to 60 percent of the 3,390 children screened over 100 service days, infection control/supply costs per child would equal $5.30.
This methodology allows SSPs to estimate costs with minimal data collection and time.
开发一种估算学校封釉计划（SSP）所用资源年度成本的方法并展示其应用。
我们利用现有文献和专家意见，确定 SSP 成本构成及最适合其测量的单位（例如，每个操作人员）和采集频率（例如，每天）。对于设备和可重复使用的器械，SSP 之间的成本具有足够的同质性，我们可以提供默认的单位成本估算（2016 年美元），供 SSP 替代自己收集数据时使用。我们还提供了供应物品的默认成本，以便 SSP 可以根据所用封釉材料、封釉站数量、操作人员数量、服务提供天数、筛查/封釉儿童数量以及封釉牙齿数量等特定于计划的信息来估算总供应成本。对于其余的三个类别（劳动力、里程和行政），成本因 SSP 而异，我们需要开发并试用特定于计划的数据采集日志。
根据计划特点，每个封釉站的年度成本在 584 美元至 797 美元之间。对于一个假设的 SSP，假设其每个站配备两名操作人员（卫生员和助手），按照国家费率支付工资，每小时的劳动力成本将等于 77.97 美元。假设该 SSP 使用一次性器械、光固化封釉剂，并为 100 个服务日中筛查的 3390 名儿童中的 60%提供封釉剂（每名儿童 3 个），则每个儿童的感染控制/供应成本将等于 5.30 美元。
这种方法允许 SSP 以最小的数据收集和时间来估算成本。
