Background:
Quality indicators were adopted to compare quality of care across health systems.
Aim:
To evaluate whether patient characteristics influence primary care physicians' diabetes quality indicators.
Design Of Study:
Retrospective cohort study.
Setting:
Primary care setting.
Method:
The study was conducted in the Central District of Clalit Health Service in Israel. The five measures of diabetes follow-up were: the percentage of patients with diabetes for whom glycosylated haemoglobin (HbA(1c)), microalbumin, low-density lipoprotein (LDL)-cholesterol, and blood pressure were measured at least once, and the percentage of patients who were seen by an ophthalmologist, during 2005. Three outcome measures were chosen: the percentage of patients with diabetes and HbA(1c) <7 mg%, the percentage of patients with diabetes and blood pressure <130/80 mmHg, and the percentage of patients with diabetes and LDL-cholesterol <100 mg/dl in 2005. Sociodemographic information was retrieved about all the physicians' patients with diabetes.
Results:
One-hundred and seventy primary care physicians took care of 18 316 patients with diabetes. The average number of patients with diabetes per physician was 107 (range 10-203). A lower quality indicator score for HbA(1c) <7 mg% was correlated with a higher percentage of patients of low socioeconomic status (P<0.001) and new immigrants (P = 0.002), and correlated with borderline significance with higher mean patients' body mass index (P = 0.024); lower quality indicator score for blood pressure <130/80 mmHg was related to higher patients' age (P = 0.006). None of the diabetes follow-up measures were related to patients' characteristics.
Conclusion:
Achieving good glycaemic control is dependent on patient characteristics. New immigrants, patients of low socioeconomic status, and older patients need special attention to avoid disparities.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care evaluation by...
