## Form to compute the financial losses due to a certain medical condition in a population

This form calculates the estimated productivity losses in a population (e.g., a country, or an organization) due to various medical conditions (e.g., diabetes, anxiety disorders, burnout, etcetera).

It generates a number that represents "annual costs", that is, the annual financial losses incurred by that population due to that medical condition.

Population size:

Incidence of the condition:

**Duration of the episode**. (This is how long that medical condition lasts, on average. This information is typically found in the literature. For instance, the average duration of a depressive episode is 8 months. For Generalized Anxiety Disorder, or for substance abuse, in the absence of treatment, it can be a lifetime. For the flu, it is about two weeks).

*IMPORTANT: enter the duration of the episode in YEARS, not in months or days. For instance, if the duration of that episode is 8 months, enter 0.66; If it is 6 months, enter 0.5; If it is 18 months, enter 1.5. *

*NOTE: if the duration is less than one year, then enter that decimal value. It will generate the annual costs of that condition in that population. However, if the duration is more than one year, enter "1" if you want to calculate the annual costs, or enter the actual number of years (e.g., 20) if you want to calculate the total costs associated with that condition in that population. *

Duration of the episode:

Productivity loss due to that medical condition:

*NOTE: enter only the number, not the actual currency you want to compute this in. The currency is just something for you to keep in mind when you interpret the results.*

**LEGEND**

COSTS = the financial losses (annual or total, depending on the duration of the episode you entered) incurred by that entity (country / organization) due to the existence of that medical condition in that population.

**EXAMPLE**

Let's talk about a concrete example. Let's say that we have a company employing 10000 people, with a gross average salary of 100000 $/year. Let's say that, based on a prior organizational assessment, we know that the (point) prevalence of depression in this organization is 12% (i.e., 0.12). We also know from literature that the average duration of a depressive episode is 8 months (i.e., 0.66 years). Furthermore, we know from the scientific literature that the average productivity loss for depression is approximately 20% (i.e., 0.20). With these numbers, we can now calculate the financial losses due to depression in this organization.

The results for this hypothetical organization are:

ANNUAL COSTS OF DEPRESSION IN THIS POPULATION = 15840000 dollars per year

This means that, each year, this organization loses approximately 15 million dollars due to the existence of this medical condition in its employees. Other medical conditions in this population will increase these costs further. This number also suggests that intervention programs for depression in this population will likely lead to substantial savings and profit increases.
