How much convergence exists between registered process measures and patient reported experience measures? A study on Catalan primary healthcare

The use of quality measures is important for transparency and the continuous improvement of performance. However, we do not know enough about the relationship between registered process measures and patient reported experience measures (PREMs) in primary healthcare. Recent studies point to areas of convergence that run contrary anticipated trends. This is a relevant question for healthcare management and governments as their position is stronger when system's guidelines and targets also matter to patients or, vice versa, when patient‐centered measures are used to develop new process measures. Our aim is to study both type of measures, their logic and their level of convergence. We also assess the relationship between PREMs, patients' demographic characteristics and area socioeconomic level. We estimated pairwise correlations with patient experience aggregated at the health‐center level and a series of multilevel regression models to assess the adjusted effect of four registered process measures on ratings of patient experience at the patient level. We use patient experience as measured by survey data, two composite quality indices and two single indicators regularly computed by the Catalan Health Service. Continuity of care with the same doctor and accessibility are positively associated with patient experience. No relationship was observed in the index created to measure quality of assistance. The index measuring the quality of prescriptions was positively associated with patient experience but only when analyzed separately. We conclude that registered process measures and PREMs are not entirely independent, hence improvements of the management side have the potential to impact patient experience.
