Brief Report: Financial Burden of Toxoplasmosis Encephalitis Treatment at a Safety Net Hospital.

BACKGROUND

Although the price increase of pyrimethamine in 2015 received heavy media coverage, there are little data regarding specific implications to hospitals and the total costs of treating inpatients with toxoplasmosis encephalitis (TE).

METHODS

Using average drug wholesale costs, we estimated the inpatient drug costs of TE drugs 3 years prepyrimethamine and postpyrimethamine price increase in August 2015. The drug regimens and total doses were determined through retrospective chart review of patients living with HIV who received treatment for TE while inpatient during this period.

RESULTS

The 3-year pre-increase TE drug costs for 66 admissions were estimated at $50,310 compared with a total drug cost of $1,026,006 for 61 admissions postincrease. Pyrimethamine made up 98% of the drug costs postincrease, compared with 57% pre-increase. Pyrimethamine-based regimens were the most frequently used throughout the study period.

CONCLUSIONS

The price increase of pyrimethamine in 2015 led to a substantial and unnecessary financial burden to hospitals. This required health care systems to shift valuable resources to continue to provide medications to a vulnerable patient population. There has been more focus on providing high-value care in recent years. Our study highlights the need for further examination of pharmaceutical companies' arbitrary determination of medication costs and how they contribute to patient care.
