Indicator 11.5: "Average number of medical injections per person per year"
Average number of medical injections per person per year
Population-based survey such as the DHS/AIS
What It Measures
Injection overuse contributes to the transmission of blood borne pathogens through health care injections as it amplifies the effect of unsafe practices. This indicator captures the number of injections received each year to document trends in the effectiveness of interventions to decrease injection overuse.
How to Measure It
In a population survey men and women aged 15-49 are asked: • if they have had any injections for any reason in the last twelve months; • if yes, how many. (In older surveys, some questionnaires asked if respondents had received any injections in the last 6 months. In this case, the frequency of injections is multiplied by two to arrive at the frequency for the year. In other cases, population-based surveys have given only the 6 month rate.) It should be noted that medical injections can be self-administered (e.g., insulin for diabetes). These injections should NOT be included in the numerator. The indicator should be reported separately for men and women.
Strengths and Limitations
The distribution of the frequency of injections received is usually skewed to the right. A small proportion of the population (e.g., diabetics) receives a substantial proportion of all injections. Thus, population surveys using a small sample size may underestimate the annual number of injections per person because none of the persons receiving many injections were included in the sample.
