No previous study, to the best of our knowledge, has examined both the time trend and impact of not having insurance or prescription medication cost coverage (PMCC) on the usage of type 2 diabetes and hypertension oral medications in Ontario and New Brunswick, Canada.
We used data from the Canadian Community Health Survey (CCHS) from 2007 to 2014 to examine the time trend and impact of PMCC. A multivariable-adjusted logistic regression model was fitted.
The pseudo-cohort included 23,215 individuals representing a population of approximately 8.7 million people. Overall, 20.0% of respondents reported absence of PMCC. This proportion increased slightly from 19.6% (95% confidence interval [CI] 95% CI [17.5, 22.5]) to 20.7% (95% CI [16.9, 23.1]). Adjusted odds ratios (OR) showed that uninsured individuals were 23% less likely to use their medications (OR = 0.77, 95% CI [0.657, 0.911]).
There was a slight decline in PMCC over time and this decline was associated with reduced use of medications for type 2 diabetes and hypertension.
据我们所知，之前没有研究考察过在加拿大安大略省和新不伦瑞克省，没有保险或处方药费用覆盖（PMCC）对 2 型糖尿病和高血压口服药物使用的时间趋势和影响。
我们使用了 2007 年至 2014 年加拿大社区健康调查（CCHS）的数据来检查 PMCC 的时间趋势和影响。使用多变量调整逻辑回归模型进行拟合。
伪队列包括 23215 名代表约 870 万人的个体。总体而言，20.0%的受访者报告缺乏 PMCC。这一比例从 19.6%（95%置信区间[CI]95% CI [17.5, 22.5]）略有增加到 20.7%（95%置信区间[CI] [16.9, 23.1]）。调整后的优势比（OR）表明，未参保者使用药物的可能性降低了 23%（OR=0.77，95% CI [0.657, 0.911]）。
随着时间的推移，PMCC 略有下降，而这种下降与 2 型糖尿病和高血压药物使用减少有关。
