You also want to account for the 150 people who never had or developed HIV over the 10-year period, (150 * 10) contributing 1500 person-years of disease-free life. That is a total of (1500 + 275) = 1775 person-years of life. Now take the 50 new cases of HIV, and divide by 1775 to get 0.028, or 28 cases of HIV per 1000 population, per year.
For the more general case of a life time health profile (i.e., experiencing more than one health state during the remaining years of life), the utility of a life time health profile must equal the sum of single-period utilities. [19] Because of these theoretical assumptions, the meaning and usefulness of the QALY is debated.
All additional years of life gained from a treatment are considered to be “full health,” regardless of the state of the patient. [7] “Full health” is defined as the average health of the population, and set at 0.851 on a 0-1 scale. [8] In effect, this measure makes treatments appear to have a greater impact if they extend the patients ...
Lifetime prevalence (LTP) is the proportion of individuals in a population that at some point in their life (up to the time of assessment) have experienced a "case" (e.g., a disease, a traumatic event, or, a behavior, such as committing a crime). Often, a 12-month prevalence (or some other type of "period prevalence") is provided in conjunction ...
A common statistic associated with length of stay is the average length of stay (ALOS), a mean calculated by dividing the sum of inpatient days by the number of patients admissions with the same diagnosis-related group classification. A variation in the calculation of ALOS can be to consider only length of stay during the period under analysis.

The Healthy Life Years (HLY) indicator, also known as disability-free life expectancy (DFLE) or Sullivan's Index, is a European structural indicator computed by Eurostat. It is one of the summary measures of population health, known as health expectancies, [ 1 ] composite measures of health that combine mortality and morbidity data to represent ...
