PMID 33394625WHAT IT FOUND
Polish adults with hypertension reported their self-care behaviours and confidence.
Scores were highest for managing high blood pressure and lowest for daily self-care habits, but the questionnaire did not separate patients with normal and abnormal blood pressure.
Key findings
01In the 250 analysed patients, self-care management scores were highest (64.17) and self-care maintenance scores were lowest (56.73) on a 0 to 100 scale.
02Answers within each subscale were reasonably consistent, with Cronbach α values of 0.755 for maintenance, 0.746 for management, and 0.892 for confidence.
03Self-care scores did not differ between patients with normal and abnormal blood pressure.

What it does not show
Only 250 patients from one hypertension clinic in Wroclaw were analysed, so the findings may not apply to other settings or to inpatients. Eighteen of the 268 patients who consented dropped out without giving a reason. The study used only this questionnaire and did not compare it with another self-care measure. There was no retest, so the questionnaire's stability over time was not shown. There are no normal ranges or cutoff values for high and low self-care scores. The original three-factor structure was not directly confirmed and required model modifications. Scores did not distinguish patients with normal blood pressure from those with abnormal blood pressure.

The easy way to misread this
Do not read the Polish SC-HI as a way to identify patients with poor blood pressure control. Scores were similar in patients with normal and abnormal blood pressure, and the study did not provide cutoff values for high or low self-care.
