The Cost of Procuring Deceased Donor Livers: Evidence From US Organ Procurement Organization Cost Reports, 2013-2018.

Deceased donor organs for transplantation are costly. Expenses include donor assessment, pre-operative care of acceptable donors, surgical organ recovery, preservation and transport, and other costs. US Organ Procurement Organizations (OPOs) serve defined geographic areas in which each OPO has exclusive organ recovery responsibilities including detailed reporting of costs. We sought to determine the costs of procuring deceased donor livers by examining reported organ acquisition costs from OPO cost reports. Using 6 years of US OPO cost report data for each OPO (2013-2018), we determined the average cost of recovering a viable (i.e., transplanted) liver for each of the 51 independent US OPOs. We examined predictors of these costs including the number of livers procured, the percent of nonviable livers, direct procurement costs, coordinator salaries, professional education, and local cost of living. A cost curve estimated the relationship between the cost of livers and the number of locally procured livers. The average cost of procured livers by individual OPO-year varied widely from $11 393 to $65 556 (average $31 659) over the six study years. An increase in the overall number of procured livers was associated with lower direct costs, administrative, and procurement overhead costs, but this association differed for imported livers. Cost per local liver decreased linearly for each additional liver, while importing more livers was only cost saving until 200 livers, with imported livers costing more ($39K vs. $31.7K). The largest predictor of variation in cost was the aggregate of direct costs (e.g., hospital costs) to recover the organ (57%). Cost increases were 2.5% per year (+$766/year). This information may be valuable in determining how OPOs might improve service to transplant centers and the patients they serve.

The cost of procuring deceased donor kidneys: Evidence from OPO cost reports 2013-2017.

Using 5 years of US organ procurement organization (OPO) data, we determined the cost of recovering a viable (ie, transplanted) kidney for each of 51 OPOs. We also examined the effects on OPO costs of the recovery of nonviable (ie, discarded) kidneys and other OPO metrics. Annual cost reports from 51 independent OPOs were used to determine the cost per recovered kidney for each OPO. A quadratic regression model was employed to estimate the relationship between the cost of kidneys and the number of viable kidneys recovered, as well as other OPO performance indicators. The cost of transplanted kidneys at individual OPOs ranged widely from $24 000 to $56 000, and the average was $36 000. The cost of a viable kidney tended to decline with the number of kidneys procured up to 549 kidneys per year and then increase. Of the total 81 401 kidneys recovered, 66 454 were viable and 14 947 (18.4%) were nonviable. The costs of kidneys varied widely over the OPOs studied, and costs were a function of the recovered number of viable and nonviable organs, local cost levels, donation after cardiac death, year, and Standardized Donor Rate Ratio. Cost increases were 3% per year.

Changing Metrics of Organ Procurement Organization Performance in Order to Increase Organ Donation Rates in the United States.

The shortage of deceased-donor organs is compounded by donation metrics that fail to account for the total pool of possible donors, leading to ambiguous donor statistics. We sought to assess potential metrics of organ procurement organizations (OPOs) utilizing data from the Nationwide Inpatient Sample (NIS) from 2009-2012 and State Inpatient Databases (SIDs) from 2008-2014. A possible donor was defined as a ventilated inpatient death ≤75 years of age, without multi-organ system failure, sepsis, or cancer, whose cause of death was consistent with organ donation. These estimates were compared to patient-level data from chart review from two large OPOs. Among 2,907,658 inpatient deaths from 2009-2012, 96,028 (3.3%) were a "possible deceased-organ donor." The two proposed metrics of OPO performance were: (1) donation percentage (percentage of possible deceased-donors who become actual donors; range: 20.0-57.0%); and (2) organs transplanted per possible donor (range: 0.52-1.74). These metrics allow for comparisons of OPO performance and geographic-level donation rates, and identify areas in greatest need of interventions to improve donation rates. We demonstrate that administrative data can be used to identify possible deceased donors in the US and could be a data source for CMS to implement new OPO performance metrics in a standardized fashion.

The organ procurement costs of expanding deceased donor organ acceptance criteria: Evidence from a cost function model.

A potential solution to the deceased donor organ shortage is to expand donor acceptability criteria. The procurement cost implications of using nonstandard donors is unknown. Using 5 years of US organ procurement organization (OPO) data, we built a cost function model to make cost projections: the total cost was the dependent variable; production outputs, including the number of donors and organs procured, were the independent variables. In the model, procuring one kidney or procuring both kidneys from double/en bloc transplantation from a single-organ donor resulted in a marginal cost of $55 k (95% confidence interval [CI] $28 k, $99 k) per kidney, and procuring only the liver from a single-organ donor results in a marginal cost of $41 k (95% CI $12 k, $69 k) per liver. Procuring two kidneys for two candidates from a donor lowered the marginal cost to $36 k (95% CI $22 k, $66 k) per kidney, and procuring two kidneys and a liver lowers the marginal cost to $24 k (95% CI $17 k, $45 k) per organ. Economies of scale were observed, where high OPO volume was correlated with lower costs. Despite higher cost per organ than for standard donors, kidney transplantation from nonstandard donors remained cost-effective based on contemporary US data.
