Since, at the health system level, there is little research into the possible interrelationships among the various indicators of health, healthcare performance, non-medical determinants of health, and community and health system characteristics, we conducted this study to explore such interrelationships using the Canadian Health Indicators Framework.
We conducted univariate correlational analyses with health and healthcare performance as outcomes using recent Canadian data and the ten Canadian provinces and three territories as units of the analyses. For health, 6 indicators were included. Sixteen healthcare performance indicators, 12 non-medical determinants of health and 16 indicators of community and health system characteristics were also included as independent variables for the analysis. A set of decision rules was applied to guide the choice of what was considered actual and preferred performance associations.
Health (28%) correlates more frequently with non-medical determinants than healthcare does (12%), in the preferred direction. Better health is only correlated with better healthcare performance in 13% of the cases in the preferred direction. Better health (24%) is also more frequently correlated with community and health system characteristics than healthcare is (13%), in the preferred direction.
Canadian health performance is a function of multiple factors, the most frequent of which may be the non-medical determinants of health and the community characteristics as against healthcare performance. The contribution of healthcare to health may be limited only to relatively small groups which stand to benefit from effective healthcare, but its overall effect may be diluted in summary measures of population health. Interpreting multidimensional, multi-indicator performance data in their proper context may be more complex than hitherto believed.
由于在卫生系统层面,对于健康的各项指标、医疗保健绩效、健康的非医疗决定因素以及社区和卫生系统特征之间可能存在的相互关系研究较少,我们开展了这项研究,以利用加拿大健康指标框架探索此类相互关系。
我们以加拿大最近的数据以及十个加拿大省份和三个地区作为分析单位,以健康和医疗保健绩效为结果进行单变量相关分析。对于健康,纳入了6项指标。还纳入了16项医疗保健绩效指标、12项健康的非医疗决定因素以及16项社区和卫生系统特征指标作为分析的自变量。应用了一组决策规则来指导对实际和理想绩效关联的选择。
在理想方向上,健康(28%)与非医疗决定因素的相关性比医疗保健(12%)更频繁。在理想方向上,仅有13%的情况显示更好的健康与更好的医疗保健绩效相关。在理想方向上,更好的健康(24%)与社区和卫生系统特征的相关性也比医疗保健(13%)更频繁。
加拿大的健康绩效是多种因素的函数,其中最常见的因素可能是健康的非医疗决定因素和社区特征,而非医疗保健绩效。医疗保健对健康的贡献可能仅局限于可能从有效医疗保健中受益的相对较小群体,但其总体效果在人群健康的综合衡量指标中可能会被稀释。在适当背景下解读多维、多指标的绩效数据可能比以往认为的更为复杂。
