"deficit index" is a correct and usable phrase in written English.
It is typically used to refer to a numerical measurement or indicator of a shortage or lack in something. It may be used in a variety of contexts, such as economics, healthcare, education, and politics. Example: According to the latest deficit index, the country's budget deficit has reached record levels due to excessive government spending.
The Normalized Deficit Index (NDI) shows within-year water deficit.
A significant relationship was found between the plant water deficit index (PWDI) and the root-weighted (rather than the arithmetic) average SWC over root zone.
The agricultural drought was quantified using soil water deficit index (SWDI) derived based on available soil moisture and basic soil water parameters.
In the present work, a new approach to define the soil water deficit index (SWDI) is analyzed to use a soil water series for drought monitoring.
Agricultural drought is quantified using the Soil Water Deficit Index (SWDI) based on SMAP and soil properties (field capacity and available water content) information.
The team then developed two risk metrics to assess the impact of within-year dry periods (Normalized Deficit Index, or NDI) and over multiple years (Normalized Deficit Cumulated, or NDC).
We used an array of 85 health-related deficits covering major health dimensions including depression, cognition, morbidity, physical performance, and disability to construct several deficit indices (DIs) with overlapping and complementary sets of deficits to test robustness of the estimates.
Further studies confirm that the risk of adverse outcomes is defined more precisely by deficit indices than by phenotypic definitions of frailty [30].

Also absent from the accumulation of deficits index is any temporal ordering of deficits.
Pilotto et al 6 compared the accuracy of four measures of frailty (the SOF index, the cumulative deficits index, the Comprehensive Geriatric Assessment [CGA], and the Multidimensional Prognostic Index [MPI]) in a sample of hospitalized older adults.
