title: Cost of neutropenic complications of chemotherapy.
abstract: BACKGROUND
  Cost of neutropenic complications of myelosuppressive chemotherapy has been reported to be substantial. Prior research, however, has focused on initial hospitalization only and has failed to account for follow-on care.
  
  
  METHODS
  Using a US health-care claims database, all adult cancer patients who received a course of chemotherapy were identified. For each such patient, each unique cycle of chemotherapy within the course and each occurrence of neutropenic complications within these cycles were characterized. Patients developing neutropenic complications in a given cycle (neutropenia patients), starting with the first, were matched (1:1) to those who did not develop neutropenic complications in that cycle (comparison patients), and health-care costs (i.e. expenditures) were tallied for each matched pair.
  
  
  RESULTS
  Neutropenia patients (n = 373) and comparison patients were similar in terms of baseline characteristics. Costs of neutropenia-related care were $12,397 (95% confidence interval $10,274-$14,754) higher for neutropenia versus comparison patients [$14,407 ($12,357-$16,743) versus $2010 ($1490-$2553)]. Among neutropenia patients, mean cost of initial hospitalization for neutropenic complications was $7813 ($6537-$9379); cost of all subsequent neutropenia-related care averaged $6594 ($5217-$8272).
  
  
  CONCLUSIONS
  Neutropenic complications of myelosuppressive chemotherapy are costly. Prior research focusing on initial hospitalization only may have underestimated the cost of these complications by as much as 40%.
