1 When studying social factors at the community level, some strata of social variables may only contain participants who could never be exposed to aggregate level exposures of interest.
"With their ability to influence behaviour at the family and community level and across all social strata, religious leaders have enormous power to effect real and lasting change in the lives of children".
Generally, opioid related death rates were reduced in those communities that implemented OEND compared with community-year strata with no OEND implementation.
Groups included community-year strata with no implementation, those below the median (low implementers), and community-year strata with enrollment rates above the median (high implementers).
Both community-year strata with 1-100 enrollments per 100 000 population (adjusted rate ratio 0.73, 95% confidence interval 0.57 to 0.91) and community-year strata with greater than 100 enrollments per 100 000 population (0.54, 0.39 to 0.76) had significantly reduced adjusted rate ratios compared with communities with no implementation.
As in other studies of injury trends 35 and program implementation, 36 we used Poisson regression models to test our hypotheses that those community-year strata with higher implementation would have lower rates.
Design Interrupted time series analysis of opioid related overdose death and acute care utilization rates from 2002 to 2009 comparing community-year strata with high and low rates of OEND implementation to those with no implementation.
32 We calculated the proportion of schedule II opioid prescriptions dispensed to doctor shoppers per total opioid prescriptions for each community-year stratum.
We also refit models substituting acute care utilization rates associated with non-fatal opioid related poisoning with non-fatal opioid related poisoning or non-fatal motor vehicle traffic related injury rate ratio for each community-year stratum.
To adjust for these three treatment services, we calculated population rates of methadone maintenance, buprenorphine maintenance, and detox events for each community-year stratum using data from the Massachusetts Department of Public Health Bureau of Substance Abuse Services treatment database.
