简要总结
In 2001, an estimated 1.9 million Canadians had chronic renal disease and the number of patients being treated for end stage renal disease climbed by nearly 20% in 5 years. Many medications commonly used in elderly patients are excreted by the kidney. Failure to adjust doses in those with impaired renal function can result in medication overdose, leading to potentially serious morbidity and mortality. Studies in hospitals and long term care facilities have found a 19-67% rate of non-compliance with guidelines for medication dose adjustment in patients with renal insufficiency and in ambulatory care one study found a 69% rate of non-compliance. Since primary care physicians write 80% of prescriptions for those aged 65 years, there is a need for interventions to improve prescribing to patients with renal impairment in primary care.
This study will develop an audit tool and electronic decision support tool that will be incorporated into the electronic medical record in a large academic family health centre. It is seen as a preliminary step in a project to assess the effectiveness of a multifaceted intervention including chart audit, personalized feedback to prescribers, a pharmacist-facilitated group learning session and the use of an electronic decision support tool incorporated into the electronic medical record.
详细描述
Study Design:
This descriptive study will develop and pilot test the tools for a multifaceted intervention to improve prescribing to patients with renal impairment in primary care. These tools include a chart audit tool, development of a group learning session and an electronic clinical decision support tool that will be incorporated into the electronic medical record.
Setting:
This study will be conducted at Stonechurch Family Health Centre, an academic family practice teaching site of McMaster University. Stonechurch Family Health Centre currently provides primary care to about 16,000 patients. There are three interdisciplinary clinical teams that include academic and community family physicians, nurse practitioners, registered nurses, RPNs, a pharmacist, social workers and other professionals. Approximately 9.5% of the patient population is elderly.
Stonechurch Family Health Centre uses the Open Source Clinical Application Resource (OSCAR) system as its electronic medical record (EMR). OSCAR was developed by Dr. David Chan and colleagues and has the benefit of integrating clinical practice with clinical knowledge and delivering necessary tools including pharmaceutical and other clinical reference at the point of care. OSCAR has been used at Stonechurch since April 2002 and the transition from paper chart to electronic records has been successfully completed for all practices within the practice site
