Interventions to Improve Medication Reconciliation in Primary Care

Objective: To systematically review all primary care intervention studies designed to implement medication reconciliation for effects on medication discrepancies, clinical outcomes, and patient knowledge of their medications. Data Sources: We searched MEDLINE (1988–March 2008); Healthstar (1966–March 2008): CINAHL (1982–March 2008); EMBASE (1980–March 2008); Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, Cochrane Methodology Register, and Health Technology Assessments; and unpublished material. No language restrictions were applied. Search terms included medication reconciliation, medication errors, prescribing error, medication systems, adverse drug events, drug utilization review, medication list, medication record, and medications management. Study Selection And Data Abstraction: Randomized controlled trials or before-and-after studies that examined the effect of various interventions on medication discrepancies either in ambulatory settings or at hospital discharge among community-dwelling adults were included. Two reviewers independently assessed studies to determine inclusion. Level of agreement between the reviewers was good, with unweighted Cohens κ of 0.71. Two of 3 independent reviewers abstracted data and evaluated validity from included studies. Disagreements between reviewers were resolved by consensus. Data Synthesis: Four trials met the inclusion criteria. Two before-and-after studies (n = 275) in ambulatory care examining systematic medication reconciliation at each visit produced conflicting results. One study showed a reduction in the proportion of medication discrepancies from 88.5% to 49.1% (OR 0.13; 95% CI 0.07 to 0.21); the other showed no benefit. One randomized controlled trial and one before-and-after study (n = 202) evaluated pharmacist medication review at hospital discharge. Neither showed a benefit. Heterogeneity precluded pooling of studies. All included studies had significant design flaws. Conclusions: There is no good quality evidence demonstrating the effectiveness of medication reconciliation in the primary care setting. Further research is needed.

Admission factors associated with international medical graduate certification success: a collaborative retrospective review of postgraduate medical education programs in Ontario

BACKGROUND The failure rate on certification examinations of The College of Family Physicians of Canada (CFPC) and the Royal College of Physicians and Surgeons of Canada (RCPSC) is significantly higher for international medical graduates than for Canadian medical school graduates. The purpose of the current study was to generate evidence that supports or refutes the validity of hypotheses proposed to explain the lower success rates. METHODS We conducted retrospective analyses of admissions and certification data to determine the factors associated with success of international medical graduate residents on the certification examinations. International medical graduates who entered an Ontario residency program between 2005 and 2012 and had written a certification examination by the time of the analysis (2015) were included in the study. Data available at the time of admission for each resident, including demographic characteristics, previous experiences and previous professional experiences, were collected from each of the 6 Ontario medical schools and matched with certification examination results provided by The CFPC and the RCPSC. We developed logistic regression models to determine the association of each factor with success on the examinations. RESULTS Data for 900 residents were analyzed. The models revealed resident age to be strongly associated with performance across all examinations. Fluency in English, female sex and the Human Development Index value associated with the country of medical school training had differential associations across the examinations. INTERPRETATION The findings should contribute to an improved understanding of certification success by international medical graduates, help residency programs identify at-risk residents and underpin the development of specific educational and remedial interventions. In considering the results, it should be kept in mind that some variables are not amenable to changes in selection criteria.
