Expectations of clinical teachers and faculty regarding development of the CanMEDS-Family Medicine competencies: Laval developmental benchmarks scale for family medicine residency training.

BACKGROUND: The CanMEDS-Family Medicine (CanMEDS-FM) framework defines the expected terminal enabling competencies (EC) for family medicine (FM) residency training in Canada. However, benchmarks throughout the 2-year program are not yet defined. PURPOSES: This study aimed to identify expected time frames for achievement of the CanMEDS-FM competencies during FM residency training and create a developmental benchmarks scale for family medicine residency training. METHODS: This 2011-2012 study followed a Delphi methodology. Selected faculty and clinical teachers identified, via questionnaire, the expected time of EC achievement from beginning of residency to one year in practice (0, 6, 12, […] 36 months). The 15-85th percentile intervals became the expected competency achievement interval. Content validity of the obtained benchmarks was assessed through a second Delphi round. RESULTS: The 1st and 2nd rounds were completed by 33 and 27 respondents, respectively. A developmental benchmarks scale was designed after the 1st round to illustrate expectations regarding achievement of each EC. The 2nd round (content validation) led to minor adjustments (1.9±2.7 months) of intervals for 44 of the 92 competencies, the others remaining unchanged. CONCLUSIONS: The Laval Developmental Benchmarks Scale for Family Medicine clarifies expectations regarding achievement of competencies throughout FM training. In a competency-based education system this now allows identification and management of outlying residents, both those excelling and needing remediation. Further research should focus on assessment of the scale reliability after pilot implementation in family medicine clinical teaching units at Laval University, and corroborate the established timeline in other sites.

Determinants and time course of the postthrombotic syndrome after acute deep venous thrombosis.

BACKGROUND: The reason some patients with deep venous thrombosis (DVT) develop the postthrombotic syndrome is not well understood. OBJECTIVE: To determine the frequency, time course, and predictors of the postthrombotic syndrome after acute DVT. DESIGN: Prospective, multicenter cohort study. SETTING: 8 Canadian hospital centers. PATIENTS: 387 outpatients and inpatients who received an objective diagnosis of acute symptomatic DVT were recruited from 2001 to 2004. MEASUREMENTS: Standardized assessments for the postthrombotic syndrome using the Villalta scale at 1, 4, 8, 12, and 24 months after enrollment. Mean postthrombotic score and severity category at each interval was calculated. Predictors of postthrombotic score profiles over time since diagnosis of DVT were identified by using linear mixed modeling. RESULTS: At all study intervals, about 30% of patients had mild (score, 5 to 9), 10% had moderate (score, 10 to 14), and 3% had severe (score >14 or ulcer) postthrombotic syndrome. Greater postthrombotic severity category at the 1-month visit strongly predicted higher mean postthrombotic scores throughout 24 months of follow-up (1.97, 5.03, and 7.00 increase in Villalta score for mild, moderate, and severe 1-month severity categories, respectively, vs. none; P < 0.001). Additional predictors of higher scores over time were venous thrombosis of the common femoral or iliac vein (2.23 increase in score vs. distal [calf] venous thrombosis; P < 0.001), higher body mass index (0.14 increase in score per kg/m(2); P < 0.001), previous ipsilateral venous thrombosis (1.78 increase in score; P = 0.001), older age (0.30 increase in score per 10-year age increase; P = 0.011), and female sex (0.79 increase in score; P = 0.020). LIMITATIONS: Decisions to prescribe compression stockings were left to treating physicians rather than by protocol. Because international normalized ratio data were unavailable, the relationship between anticoagulation quality and Villalta scores could not be assessed. CONCLUSION: The postthrombotic syndrome occurs frequently after DVT. Patients with extensive DVT and those with more severe postthrombotic manifestations 1 month after DVT have poorer long-term outcomes.

Variations in heritability of cortisol reactivity to stress as a function of early familial adversity among 19-month-old twins.

CONTEXT: Cortisol reactivity is a marker of vulnerability for a variety of stress-related diseases that likely arise from the contributions of both genetic and environmental sources of influence. However, little is known about gene-environment interplay in early cortisol reactivity. OBJECTIVES: To examine the genetic and environmental contributions to early cortisol reactivity in a population-based sample of 19-month-old twins and to determine whether these contributions vary as a function of early familial adversity. DESIGN: A variant of the twin method, with genetic and environment contributions to cortisol reactivity estimated as a function of familial adversity. Familial adversity was defined as the presence of 7 risk factors during perinatal and postnatal development (eg, at 6 and 19 months of age): maternal smoking during pregnancy, low birth weight, low family income, low maternal educational level, single parenthood, young motherhood, and maternal hostile or reactive behaviors. Twins exposed to 4 or more risk factors at either time were considered as having been exposed to high (vs low) familial adversity (23.4% of the sample). SETTING: Centre de Recherche Fernand-Seguin at the Hôpital Louis-Hyppolite Lafontaine, Montréal, Quebec. Patients Participants were families of twins from the Québec Newborn Twin Study recruited between April 1, 1995, and December 31, 1998, in the greater Montréal area. A total of 346 twins, 130 monozygotic and 216 dizygotic, were included in the study. MAIN OUTCOME MEASURES: Salivary cortisol samples were collected before and after the participating twins had been exposed to unfamiliar situations; change in cortisol over time was used as a measure of cortisol reactivity. RESULTS: Distinct patterns of genetic and environmental contributions to cortisol reactivity were evidenced as a function of familial adversity, suggesting a possible gene-environment interplay. In low-familial adversity settings that characterized most families, both genetic and unique but not shared environmental factors accounted for individual differences in cortisol reactivity, with shared genes explaining the similarity observed within twin pairs. By contrast, in conditions of high familial adversity, both shared and unique environmental factors, but not genetic factors, accounted for the variance in cortisol reactivity. CONCLUSION: This pattern of differing genetic and environmental contributions according to familial adversity suggests that, early in life, high familial adversity may have a programming developmental effect on cortisol reactivity.

VEINES-QOL/Sym questionnaire was a reliable and valid disease-specific quality of life measure for deep venous thrombosis.

OBJECTIVE: To assess the validity of VEINES-QOL/Sym, a patient-reported questionnaire to evaluate quality of life and symptoms in patients with deep venous thrombosis (DVT). STUDY DESIGN AND SETTING: Psychometric study within the Venous Thrombosis Outcomes (VETO) Study, a prospective cohort study of long-term outcomes after DVT. A total of 359 English- and French-speaking patients with acute, objectively diagnosed DVT were recruited at seven hospitals in Quebec, Canada. The VEINES-QOL/Sym questionnaire, a 26-item patient-reported measure that generates separate summary scores for symptoms (VEINES-Sym) and quality of life (VEINES-QOL) was evaluated for acceptability, reliability, validity, and responsiveness in VETO Study subjects. RESULTS: Standard psychometric tests confirmed the acceptability (missing data, item endorsement frequencies, floor and ceiling effects), reliability (internal consistency, item-total and inter-item correlations, test-retest), validity (content, construct, convergent, discriminant, known groups), and responsiveness to clinical change of the VEINES-QOL/Sym in patients with DVT. CONCLUSION: The VEINES-QOL/Sym is a practical and scientifically sound patient-reported measure of outcomes that was developed using gold-standard methods. VEINES-QOL/Sym is valid and reliable for use as a measure of quality of life and symptoms in patients with acute DVT and provides a rigorous tool to allow more comprehensive evaluation of outcomes in clinical trials and epidemiological studies of patients with DVT.

An 18-month prospective cohort study of functional outcome of delirium in elderly patients: activities of daily living.

OBJECTIVES: To examine delirium, chronic medical problems and sociodemographic factors as predictors of activities of daily living (ADL), basic ADL (BADL) and instrumental ADL (IADL). METHODS: A prospective cohort study of four groups of elderly patients examined in the emergency department (ED): those with delirium, dementia, neither, and both. All were aged 66 years or older and living at home. Delirium was assessed with the Confusion Assessment Method and dementia with the Informant Questionnaire on Cognitive Decline in the Elderly. Demographic variables and chronic medical problems were ascertained with questionnaires. Outcome was ADL at 6, 12 and 18 months, measured with the ADL subscale of the Older Americans Resources and Services instrument. RESULTS: Univariate analyses suggested significantly poorer ADL, particularly IADL, at 18 months in the delirium versus the non-delirium group, in the absence of dementia only. Statistically significant independent predictors of poorer ADL at 18 months in the non-dementia groups were poorer initial ADL, stroke, Parkinson's disease, hypertension and female sex. Independent predictors of poorer BADL at 18 months in the non-dementia groups were poorer initial BADL, Parkinson's disease, stroke, cancer, colds/sinusitis/laryngitis, female sex and hypertension. Independent predictors of poorer IADL at 18 months in the non-dementia groups were poorer initial IADL, stroke, never-married status, colds/sinusitis/laryngitis, arthritis and hypertension, with Parkinson's disease showing a non-significant but numerically large regression coefficient. CONCLUSION: Rather than finding delirium to be a predictor of poorer functional outcome among survivors, we found an interaction between delirium and dementia and several plausible confounders, primarily chronic medical problems, although we cannot rule out the effect of misclassification or survivor bias.

Prospective evaluation of health-related quality of life in patients with deep venous thrombosis.

BACKGROUND: To our knowledge, the burden of deep venous thrombosis from the patient's perspective has not been quantified. We evaluated health-related quality of life (QOL) after deep vein thrombosis and compared results with general population norms. METHODS: This was a multicenter prospective cohort study of 359 consecutive eligible patients with deep vein thrombosis recruited at 7 Canadian hospital centers. Quality of life was assessed at baseline and at 1 and 4 months after diagnosis using generic (36-Item Short-Form Health Survey) and disease-specific (Venous Insufficiency Epidemiological and Economic Study [VEINES]-QOL and VEINES symptom [VEINES-Sym] questionnaires) measures. Changes in QOL scores during the 4-month period were calculated, and determinants of lack of improvement in QOL were evaluated. RESULTS: During the 4 months, mean 36-Item Short-Form Health Survey physical and mental component summary scores improved by 5.1 and 4.6 points, respectively, and VEINES-QOL and VEINES-Sym scores improved by 3.1 and 2.2 points, respectively (P < .001 for time trend for all measures). However, about one third of patients had worsening of QOL during follow-up. Multivariate analyses showed that worsening of the postthrombotic syndrome score was an independent predictor of worsening of 36-Item Short-Form Health Survey physical component summary (P = .04), VEINES-QOL (P < .001), and VEINES-Sym (P < .001) scores. The 36-Item Short-Form Health Survey physical component summary scores were lower than population norms at all points assessed. CONCLUSIONS: On average, QOL improves during the 4 months following deep vein thrombosis. However, in about one third of patients, QOL deteriorates, and at 4 months, average QOL remains poorer than population norms. Worsening of the postthrombotic syndrome score is associated with worsening of QOL.

Delirium in older emergency department patients discharged home: effect on survival.

OBJECTIVES: To determine whether prevalent delirium is an independent predictor of mortality in older patients seen in emergency departments (EDs) and discharged home without admission. DESIGN: Prospective study with 18 months of follow-up. SETTING: EDs in two Montreal hospitals. PARTICIPANTS: From a cohort study of prognosis for delirium (107 delirious and 161 nondelirious subjects), 30 delirious and 77 nondelirious subjects aged 66 and older who were discharged home without admission were identified. MEASUREMENTS: Detailed interviews with patients and their proxies and review of medical charts were performed at enrollment. Trained lay interviewers determined delirium status using the Confusion Assessment Method. Subjects were followed up at 6-month intervals for a total of 18 months. Dates of death were obtained from the Ministère de la Santé et des Service Sociaux (Ministry of Health and Social Services). Survival analysis was performed using the Cox proportional hazards modeling adjusting for potential confounding variables. RESULTS: The analysis revealed a statistically significant association between delirium and mortality after adjustments for age, sex, functional level, cognitive status, comorbidity, and number of medications for the first 6 months of follow-up (hazard ratio = 7.24; 95% confidence interval = 1.62-32.35). The subjects whose delirium was not detected by the ED physician or nurse had the highest mortality over 6 months (30.8%). The mortality of delirious subjects detected in the ED was similar to that of the nondelirious subjects (11.8 vs 14.3%). CONCLUSION: The results of this study suggests that nondetection of delirium in the ED may be associated with increased mortality within 6 months after discharge. Further research is necessary to examine the effectiveness of improving detection on subsequent prognosis of older patients with delirium.
