Impact of implementing electronic clinical practice guidelines for the diagnosis, control and treatment of cardiovascular risk factors: A pre-post controlled study.

OBJECTIVE: To evaluate the impact of computerized clinical practice guidelines on the management, diagnosis, treatment, control, and follow-up of the main cardiovascular risk factors: hypertension, hypercholesterolaemia, and type 2 diabetes mellitus. DESIGN: Pre-post controlled study. SETTING: Catalonia, autonomous community located in north-eastern Spain. PARTICIPANTS: Individuals aged 35-74 years assigned to general practitioners of the Catalan Health Institute. INTERVENTION: The intervention group consisted of individuals whose general practitioners had accessed the computerized clinical practice guidelines at least twice a day, while the control group consisted of individuals whose general practitioner had never accessed the computerized clinical practice guidelines platform. MAIN OUTCOMES: The Chi-squared test was used to detect significant differences in the follow-up, control, and treatment variables for all three disorders (hypertension, hypercholesterolaemia, and type 2 diabetes mellitus) between individuals assigned to users and non-users of the computerized clinical practice guidelines, respectively. RESULTS: A total of 189,067 patients were included in this study, with a mean age of 56 years (standard deviation 12), and 55.5% of whom were women. Significant differences were observed in hypertension management, treatment and control; type 2 diabetes mellitus management, treatment and diagnoses, and the management and control of hypercholesterolaemia in both sexes. CONCLUSIONS: Computerized clinical practice guidelines are an effective tool for the control and follow-up of patients diagnosed with hypertension, type 2 diabetes mellitus, and hypercholesterolaemia. The usefulness of computerized clinical practice guidelines to diagnose and adequately treat individuals with these disorders remains unclear.

Measuring system safety for laboratory test ordering and results management in primary care: international pilot study.

The systems-based management of laboratory test ordering and results handling is a significant patient safety concern in primary care internationally. In this pilot study, we describe the testing of a method to systematically measure and monitor compliance with basic safe performance in this area in different European primary care settings. The findings show high overall compliance with the safe system measures developed although the data indicates performance variation within and between the different systems audited, which suggests that aspects of the reliability (and safety) of these systems could be improved by care teams. However, the overall utility of the method is still to be determined and this will require testing on a greater scale in more diverse practices with larger samples of patients and blood tests, and using different technology support systems.

Impact of the implementation of electronic guidelines for cardiovascular prevention in primary care: study protocol.

BACKGROUND: The electronic medical records software of the Catalan Institute of Health has recently incorporated an electronic version of clinical practice guidelines (e-CPGs). This study aims to assess the impact of the implementation of e-CPGs on the diagnosis, treatment, control and management of hypercholesterolaemia, diabetes mellitus type 2 and hypertension. METHODS: Eligible study participants are those aged 35-74 years assigned to family practitioners (FPs) of the Catalan Institute of Health. Routinely collected data from electronic primary care registries covering 80% of the Catalan population will be analysed using two approaches: (1) a cross-sectional study to describe the characteristics of the sample before e-CPG implementation; (2) a controlled before-and-after study with 1-year follow-up to ascertain the effect of e-CPG implementation. Patients of FPs who regularly use the e-CPGs will constitute the intervention group; the control group will comprise patients assigned to FPs not regularly using the e-CPG. The outcomes are: (1) suspected and confirmed diagnoses, (2) control of clinical variables, (3) requests for tests and (4) proportions of patients with adequate drug prescriptions. RESULTS: This protocol should represent a reproducible process to assess the impact of the implementation of e-CPGs. We anticipate reporting results in late 2013. CONCLUSION: This project will assess the effectiveness of e-CPGs to improve clinical decisions and healthcare procedures in the three disorders analysed. The results will shed light on the use of evidence-based medicine to improve clinical practice of FPs.
