Methods of Reducing the Risk of Mortality Associated With a Medical Treatment

A method of treatment comprising

• (a) identifying a plurality of neonates as being candidates for treatment with inhaled nitric oxide;
• (b) determining that the race of a first neonate of the plurality is non-white;
• (c) administering inhaled nitric oxide to the first neonate;
• (d) determining that the race of a second neonate of the plurality is white;
• (e) determining that the gender of the second neonate is male;
• (f) determining that the second neonate is of less than 27 weeks post-menstrual age;
• (g) determining that the fact that the second neonate is a white male of less than 27 weeks post-menstrual age means the second neonate is at a higher risk of mortality upon administration of inhaled nitric oxide compared to a female or non-white male neonate of the same post-menstrual age;
• and
• (h) administering to the second neonate a treatment that comprises mechanical ventilation or positive airway pressure support while excluding the second neonate from treatment with inhaled nitric oxide, the exclusion from treatment with inhaled nitric oxide being based on the determination of (g).
