The impact of service delivery frequency on family planning program output and efficiency.

Operations research is the study of factors that can be controlled by program administrators. Among such factors is the frequency of performing program activities. The present experiment, conducted in Lima, Peru during 1985-86, tested the impact of holding family planning post sessions once per month, twice per month, and weekly. Frequency was shown to have a major impact on program outputs, costs, and cost-effectiveness. Depending on the indicator, sessions held twice per month produced between 1.5 and 2.1 times the output of those conducted once per month. Weekly sessions produced between 1.3 and 1.6 times the output of those held twice per month. At an output level of nearly 11,200 visits per year, twice-per-month sessions were estimated to be 7-38 percent more cost-effective, depending on the indicator, than once-per-month sessions, and 6-28 percent more cost-effective than weekly sessions.
