Measuring valued output in primary care: challenges and reconciliation

IntroductionStrong primary care has positive impact on patients' and population health, and high continuity of care is one of its hallmarks. Insight into the underlying mechanisms is limited and research on this topic requires measures of primary care outputs, which are states that mediate between processes and outcomes of primary care.Areas coveredNine potential outputs of high continuity of care were specified to examine 45 validated patient questionnaires, which were identified in a systematic review. Eighteen questionnaires covered one or more primary care outputs, yet at variable and mostly limited extent.Expert opinionMeasures of primary care outputs can strengthen clinical and health services research, but such measures have yet to be developed and validated for most primary care outputs. The use of these measures in outcome evaluations of interventions in healthcare would enhance the interpretation of intervention effects. Validated measures are also needed to tap the full potential of advanced methods of data-analysis in clinical and health services research. Better understanding of the primary care outputs may also help to mitigate broader challenges in healthcare systems.
