a series of measurements, but was not registered in the SMSS was 600. The mean of the creatinine values that were both stored in the device and registered in the SMSS was significantly lower than the mean of the creatinine values that were stored in the device but not registered in the SMSS (unselected for registration): 137 (SD 35) vs. 143 μmol/l (SD 36), respectively (t =-2.5, p=.02).
Repeating both analyses with the 24 values included that could either be test values or regular measurements did not change our findings (data not shown).
Adherence to system feedback
Results are given separately for adherence to the action code (requesting patients to perform a second measurement directly) and adherence to the day conclusion (feedback that only appeared in case a second measurement was requested and registered). An overview of the feedback procedure and level of adherence to the different kinds of feedback is shown in figure 5.
Adherence to action code
In 258 cases, patients were requested to perform a second measurement directly. In 137 cases (53%), patients actually performed and registered a second measurement. In 85 cases (33%) date of registration differed from date of measurement, suggesting that delayed registration was the main reason for not adhering to feedback, as this feedback was no longer up to date when shown to the patient. In 14 cases (5%), multiple measurements were performed in advance of registration. As these multiple measurements were probably representative of actual creatinine level already, patients might not have felt the need to perform another one.
Adherence to day conclusion
In 39 cases, patients were requested to measure again the next day. In 33 cases (85%), this feedback was adhered to. In three cases, the measurements were registered several days after measurement (delayed registration), suggesting that the feedback to measure again the next day was no longer up to date when shown to these patients. In one case, the requested measurement was performed, but was not registered in the SMSS.
The advice to contact the hospital was given 24 times, which was followed up 14 times (58%). In the remaining 10 cases (concerning 10 individual patients) measurements were registered with several days delay. As feedback was no longer up to date when shown to them, this suggests delayed registration was the main reason for not adhering to the feedback to contact the hospital.
