Older persons living with dementia and their use of acute care services over 2 years in Alberta.

OBJECTIVE: To characterize transitions to acute and residential care and identify variables associated with specific transitions among community-based persons living with dementia (PLWD). DESIGN: Retrospective cohort study using primary care electronic medical record data linked with health administrative data. SETTING: Alberta. PARTICIPANTS: Adults aged 65 years or older living in the community who had been diagnosed with dementia and who saw a Canadian Primary Care Sentinel Surveillance Network contributor between January 1, 2013, and February 28, 2015. MAIN OUTCOME MEASURES: All emergency department visits, hospitalizations, residential care (supportive living and long-term care) admissions, and deaths within a 2-year follow-up period. RESULTS: In total, 576 PLWD were identified who had a mean (SD) age of 80.4 (7.7) years; 55% were female. In 2 years, 423 (73.4%) had at least 1 transition and, of these, 111 (26.2%) had 6 or more. Emergency department visits, including multiple visits, were common (71.4% had ≥1, 12.1% had ≥4). Of those hospitalized (43.8%), nearly all were admitted from the emergency department; the average (SD) length of stay was 23.6 (35.8) days, and 32.9% had at least 1 alternate level of care day. In total, 19.3% entered residential care, most admitted from hospital. Those admitted to hospital and those admitted to residential care were older and had greater historical health system use, including home care. One-quarter of the sample did not have any transitions (or die) during follow-up; they were typically younger and had limited historical health system use. CONCLUSION: Older PLWD experienced frequent, and frequently compound, transitions that have implications for them, their family members, and the health system. There was also a large proportion without transitions suggesting that appropriate supports enable PLWD to do well in their own communities. The identification of PLWD who are at risk of or who make frequent transitions may allow for more proactive implementation of community-based supports and smoother transitions to residential care.

The Assessment of Driving Fitness Using an On-Road Evaluation in Patients With Cirrhosis.

INTRODUCTION: The association between cirrhosis and driving performance is of particular clinical relevance because of the life-threatening safety issues both for the driver with cirrhosis and the general public. Study aims were to assess (i) driving competency through the use of an in-office computerized battery and on-road driving assessment (DriveABLE) and (ii) the association between minimal hepatic encephalopathy (MHE), in-office paper-pencil tools, and additional measures (e.g., frailty, depression, cognitive testing) with unsafe driving. METHODS: Patients were prospectively recruited from 2 tertiary care liver clinics. In-office tests and in-office and on-road assessments of driving competence were completed. The χ 2 test and 1-way analysis of variance were used to analyze differences among those with and without MHE. Logistic regression was used to evaluate predictors of an indeterminate/fail result on the in-office computerized driving assessment battery (DriveABLE Cognitive Assessment Tool [DCAT]). RESULTS: Eighty patients participated with a mean age of 57 years, 70% male, 75% Child-Pugh B/C, and 36% with a history of overt hepatic encephalopathy. Thirty percent met MHE criteria on both the psychometric hepatic encephalopathy score and the Stroop app tests. Only 2 patients (3%) were categorized as "unfit to drive" in the on-road driving test, one with MHE and the other without. Fifty-eight percent of the patients were scored as indeterminate/fail on the DCAT. This corresponded to a higher mean number of on-road driving errors (5.3 [SD 2.1] vs 4.2 [SD 1.6] in those who passed the DCAT, P = 0.01). Older age (odds ratio 1.3; confidence interval 1.1, 1.5; P = 0.001) and MHE by Stroop/psychometric hepatic encephalopathy score (odds ratio 11.0; confidence interval 2.3, 51.8; P = 0.002) were independently predictive of worse performance on the DCAT. DISCUSSION: Worse performance in in-office testing was associated with worse scores on a computerized driving assessment battery and more on-road driving errors, but in-office tools were insufficient to predict on-road driving failures. A diagnosis of MHE should not be used alone to restrict driving in patients with cirrhosis. At-risk patients require on-road driving tests under the supervision of driving regulatory agencies. Future studies should continue to refine and evaluate in-office or at-home testing to predict driving performance.

Rural Family Caregiving: A Closer Look at the Impacts of Health, Care Work, Financial Distress, and Social Loneliness on Anxiety.

Even before the COVID-19 pandemic, earlier acute care patient discharges, restricted admissions to long-term care, and reduced home care services increased the amount and complexity of family caregivers' care work. However, much less is known about rural caregivers' experiences. Thus, our aim in this sequential mixed-methods study was to understand how COVID-19 affected rural family caregivers. Thematically analyzed interviews and linear regression on survey data were used to understand family caregiver stress. Fourteen rural caregivers participated in interviews. They acknowledged that they benefitted from the circle of support in rural communities; however, they all reported having to cope with fewer healthcare and social services. 126 rural caregivers participated in the online survey. About a third (31%) of these caregivers had moderate frailty, indicating that they could benefit from support to improve their health. In linear regression, frailty, social loneliness, financial hardship, and younger age were associated with caregiver anxiety. Contrary to the qualitative reports that people in rural communities are supportive, over two-thirds of the rural caregivers completing the survey were socially lonely. Rural family caregivers are vulnerable to anxiety and social loneliness due to the nature of caregiving and the lack of healthcare and social service supports in rural areas. Primary healthcare and home care teams are well-positioned to assess caregivers' health and care situation as well as to signpost them to needed supports that are available in their areas.

Family Caregiving during the COVID-19 Pandemic in Canada: A Mediation Analysis.

Family caregiving is a public health issue because of caregivers' significant contribution to the health and social care systems, as well as the substantial impact that giving and receiving care has on the health and quality of life of care receivers and caregivers. While there have been many studies that associate caregivers' care work, financial difficulty, navigation, and other caregiving factors with family caregivers' psychological distress, we were interested not only in the factors related to family caregiver anxiety but also in hypothesizing how those effects occur. In this study, we used Andrew Hayes' PROCESS moderation analysis to explore the link between caregiver frailty, weekly care hours, and perceptions of financial difficulty, social support, and anxiety. In this analysis, we included 474 caregivers with relatively complete data on all of the variables. In regression analysis after controlling for gender and age, social loneliness (ß = 0.245), frailty (ß = 0.199), financial difficulty (ß = 0.196), care time (ß = 0.143), and navigation confidence (ß = 0.131) were all significant. We then used PROCESS Model 6 to determine the significance of the direct, indirect, and total effects through the serial mediation model. The model pathway from frailty to care time to financial difficulty to social loneliness to anxiety was significant. The proportions of family caregivers who were moderately frail, anxious, and experiencing social loneliness after eighteen months of the COVID-19 pandemic found in this survey should be of concern to policymakers and healthcare providers.

Outcomes of a Decision-Making Capacity Assessment Model at the Grey Nuns Community Hospital.

BACKGROUND: With an increasing elderly population, the number of persons with dementia is expected to increase and, consequently, the number of persons needing decision-making capacity assessments (DMCA) is too. However, many healthcare professionals do not feel ready to provide DMCAs. Since 2006, we implemented a DMCA Model that includes a care pathway, worksheets, education, and mentoring. The objective of this study was to assess the impact of the utilization of this patient-centered DMCA model on the need for Capacity Interviews. METHODS: This was a retrospective quality assurance chart review of patients referred for DMCA to the Geriatric Service at the Grey Nuns Community Hospital from 2006-2020. The Geriatric Service is run by Family Physicians with extra training in Care of the Elderly. We extracted patient demographics, elements of the DMCA process, and whether Capacity Interviews were performed. We used descriptive statistics to summarize the data. RESULTS: Eighty-eight patients were referred for DMCAs, with a mean age of 76 years (SD = 10.5). Dementia affected 43.2% (38/88) of patients. Valid reasons for conducting a DMCA were evident in 93% (80/86) of referrals, and DMCAs were performed in 72.6% (61/84). 85.3% (58/68) of referrals identified the need for DMCA in two to four domains, most commonly accommodation, healthcare, and finances. Two to three disciplines, frequently social workers and occupational therapists, were involved in conducting the DMCAs for 67.2% (39/58) of patients. The Capacity Assessment Process Worksheet was used 63.2% of the time. Capacity Interviews were conducted in only 20.7% of referrals. Following the DMCAs, 48.2% (41/85) of those assessed were deemed to lack capacity. CONCLUSION: This study suggests that the DMCA Model implemented has decreased the need for Capacity Interviews while simultaneously respecting patient autonomy. This is an important finding as DMCAs carried out following this process reduced the need for both a Capacity Interview and declarations of incapacity while simultaneously respecting patient autonomy and supporting patients in their decisions in accordance with the legislation.

Facilitators, barriers and considerations for the implementation of healthcare innovation: A qualitative rapid systematic review.

Family caregiving scholars recommend that health providers receive competency-based education to partner with and support family caregivers to care and to maintain their own health. While it may be relatively easy to develop competency-based education for healthcare providers, ensuring widespread uptake and spread and scale of healthcare education is critical to ensuring consistent person-centered support for all family caregivers (FCGs) throughout the care trajectory. The development of novel healthcare innovations requires implementation strategies for uptake and spread, with implementation involving the use of strategies to integrate a novel innovation into healthcare. Research suggests that there are many factors involved in successful implementation and a synthesis of potential factors is warranted. The purpose of this review is to provide an in-depth examination of facilitators, barriers and considerations for implementation of a novel healthcare innovation that will be used to develop an implementation plan for spread and scale of our competency-based education for health providers to learn about person-centered care for FCGs. A systematic review of published and grey literature was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA [Moher et al., 2015]) guidelines. The systematic review involved searching four databases for original research articles that described barriers, facilitators and/or other considerations when implementing innovations. Twenty-eight articles were included in the qualitative thematic analyses and described three areas of implementation research: barriers, facilitators and recommendations. There were major and parallel themes that emerged under facilitators and barriers. There were a wide variety of strategies that were identified as recommendations. The findings were synthesised into five considerations for implementation: Research and information sharing, intentional implementation planning, organisational underpinnings, creating the clinical context and facilitative training. This review provides an integrative overview of identified facilitators, barriers and recommendations for implementation that may aid in developing implementation strategies that can be tailored to the local context or innovation being implemented.

Potentially Inappropriate Medication Use in the Elderly.

It is estimated that approximately half of adults, older than 65 years of age, have been prescribed potentially inappropriate medications (PIMs). This study's objective was to determine the prevalence of PIM use among older patients. Two retrospective chart reviews were performed on 200 and 164 older patients who underwent comprehensive geriatric assessments (CGAs) at outpatient geriatrics clinics at the Glenrose Rehabilitation Hospital (Glenrose) in 2012-13 and at the Misericordia Community Hospital (Misericordia) in 2016-17, respectively. Outcome measures included demographics; prevalence of PIM use; common PIMs used; whether PIM use was addressed, and if so, how; and total number of oral medications. At the Glenrose, the prevalence of PIM use was 45 per cent (90/200). Of the 90 patients who had used PIMs, 46.7 per cent (42/90) had at least one of their medications stopped or modified. At the Misericordia, the prevalence of PIM use was 57.3 per cent (94/164). Of the 94 patients who used PIMs, 47.9 per cent (45/94) had at least one of their medications stopped or modified. These results suggest that an increased awareness of PIM among physicians is needed to further decrease PIM use.

A Tale of Two Solitudes: Loneliness and Anxiety of Family Caregivers Caring in Community Homes and Congregate Care.

We surveyed 604 family caregivers residing in the province of Alberta to better understand the impact of the COVID-19 pandemic on anxiety, loneliness, and care work. We assessed anxiety with the Six-Item State Anxiety Scale and loneliness with the DeJong-Gierveld Loneliness Scale. The COVID-19 pandemic created two contexts giving rise to feelings of solitude for family caregivers. Family caregivers of Albertans living in private community homes were overwhelmed with caregiving needs while those caring for Albertans living in congregate settings were restricted from caregiving. The results indicated that before the COVID-19 pandemic, 31.7% of family caregivers were anxious and 53.5% were lonely. The proportions of those who were anxious rose to 78.8% and lonely to 85.9% during the pandemic. The qualitative responses of family caregivers connected being overwhelmed with care work either in community homes or as the designated essential caregiver in congregate living settings, as well as being unable to care in congregate care settings, with anxiety and loneliness. The caregivers reporting improvements in their health and relationships with care-receivers credited spending time with the receiver doing pleasant activities together, rather than purely performing onerous care tasks. Policymakers need to consider organizing health and community services to ensure family caregivers are not overwhelmed with care tasks or excluded from caring in congregate care.

Neglected Needs of Family Caregivers during the COVID-19 Pandemic and What They Need Now: A Qualitative Study.

COVID-19 has had a negative impact on family caregivers, whether the care receivers lived with the caregiver, in a separate community home, in supportive living, or in long-term care. This qualitative study examines the points of view of family caregivers who care in diverse settings. Family caregivers were asked to describe what could have been done to support them during the COVID-19 pandemic and to suggest supports they need in the future as the pandemic wanes. Thorne's interpretive qualitative methodology was employed to examine current caregiver concerns. Thirty-two family caregivers participated. Family caregivers thought the under-resourced, continuing care system delayed pandemic planning, and that silos in health and community systems made caregiving more difficult. Family caregivers want their roles to be recognized in policy, and they cite the need for improvements in communication and navigation. The growth in demand for family caregivers and their contributions to the healthcare system make it critical that the family caregiver role be recognized in policy, funding, and practice.

The Care-of-the-Elderly Health Guide.

INTRODUCTION: The Evidence-Based Care of the Elderly Health Guide is a clinical guide with cross-references for care recommendations. This guide is an innovative adaptation of the Rourke Baby Record to support elderly care. In 2003, the guide was published with an endorsement from the Health Care-of-the-Elderly Committee of the College of Family Physicians of Canada. Since then, physicians have used the guide as a checklist and a monitoring tool for care to elderly patients. OBJECTIVE: We will update the 2003 Care-of-the-Elderly Health Guide with current published evidence-based recommendations. METHODS: This was a mixed methods study consisting of (1) the creation of a list of topics and corresponding guidelines or recommendations, (2) two focus group discussions among family physicians (n = 12) to validate the list for relevance to practice, and (3) a modified Delphi technique in a group of ten experts in Care of the Elderly and geriatrics to attain consensus on whether the guidelines/recommendations represent best practice and be included. RESULTS: The initial list contained 43 topics relevant to family practice, citing 49 published guidelines or recommendations. The focus group participants found the list of topics and guidelines potentially useful in clinical practice and emphasized the need for user-friendliness and clinical applicability. In the first online survey of the modified Delphi technique, 93% (63/66) of the references attained consensus that these represented standards of care. The other references (3/66) attained consensus in the second online survey. The final list contained 47 topics, citing 66 references. CONCLUSION: The Care-of-the-Elderly Health Guide is a quick reference to geriatric care, reviewed for relevance by family physicians and a panel of experts. The Guide is intended to be used in primary care practice.

Family Physician's and Primary Care Team's Perspectives on Supporting Family Caregivers in Primary Care Networks.

BACKGROUND: Research, practice, and policy have focused on educating family caregivers to sustain care but failed to equip healthcare providers to effectively support family caregivers. Family physicians are well-positioned to care for family caregivers. METHODS: We adopted an interpretive description design to explore family physicians and primary care team members' perceptions of their current and recommended practices for supporting family caregivers. We conducted focus groups with family physicians and their primary care team members. RESULTS: Ten physicians and 42 team members participated. We identified three major themes. "Family physicians and primary care teams can be a valuable source of support for family caregivers" highlighted these primary care team members' broad recognition of the need to support family caregiver's health. "What stands in the way" spoke to the barriers in current practices that precluded supporting family caregivers. Primary care teams recommended, "A structured approach may be a way forward." CONCLUSION: A plethora of research and policy documents recommend proactive, consistent support for family caregivers, yet comprehensive caregiver support policy remains elusive. The continuity of care makes primary care an ideal setting to support family caregivers. Now policy-makers must develop consistent protocols to assess, and care for family caregivers in primary care.

Developing a Decision-Making Capacity Assessment Clinical Pathway for Use in Primary Care: a Qualitative Exploratory Case Study.

BACKGROUND: With an ageing population, the incidence of dementia will increase, as will the number of persons requiring decision-making capacity assessments. For over 10 years, we have trained family physicians in conducting decision-making capacity assessments. Physician feedback post-training, however, has highlighted the need to integrate the decision-making capacity assessment process into the primary care context. The purpose of this study was to develop a decision-making capacity assessment clinical pathway for implementation in primary care. METHODS: A qualitative exploratory case-study design was used to obtain participants' perspectives regarding the utility of a visual algorithm detailing a decision-making capacity assessment clinical pathway for use in primary care. Three focus groups were conducted with family physicians (n=4) and allied health professionals (n=6) in two primary care clinics in Alberta. A revised algorithm was developed based on their feedback. RESULTS: In the focus groups, participants identified inconsistencies and a lack of standardization regarding decision-making capacity assessments within primary care, and provided feedback regarding a decision-making capacity assessment clinical pathway to make it more applicable to primary care. Participants described this pathway as appealing and straightforward; they also made suggestions to make it more primary care-centric. Participants indicated that the presented pathway would improve teamwork and standardization of decision-making capacity assessments within primary care. CONCLUSIONS: Use of a decision-making capacity assessment clinical pathway has the potential to standardize decision-making capacity assessment processes in primary care, and support least intrusive and least restrictive patient outcomes for community-dwelling older adults.

Decision-making capacity assessment education.

BACKGROUND/OBJECTIVES: As the elderly population and associated number of persons with dementia increase, so does the need for decision-making capacity assessments (DMCAs). Many healthcare professionals (HCPs), however, do not feel prepared to conduct DMCAs. We have provided 4-h DMCA workshops to HCPs since 2006 and offered physicians either a 3-h or 2-day DMCA workshop from 2013 to present. We evaluated the effectiveness of the workshops on self-reported key concepts of capacity. DESIGN: Pre-/post-test design. SETTING: DMCA workshops for physicians across Canada and HCPs within Alberta. PARTICIPANTS: Two hundred and eighty-one physicians and 835 HCPs. MEASUREMENTS: Pre-/post-workshop ratings on level of comfort with and understanding of 15 core DMCA concepts using 4-point Likert-type items. RESULTS: For the DMCA workshops among physicians, ten 3-h workshops were held in 2014-2015 with 166 participants and seven 2-day workshops, between 2014 and 2018, with 115 participants. With respect to the self-report on core DMCA concepts, at least 62.7% (range: 62.7%-89.6%) of physician participants had higher post-workshop ratings (sign test; p < 0.001) than pre-workshop ratings for all core DMCA concepts. For the DMCA workshops among HCPs, 4-h workshops were delivered to 835 HCP participants from 2008 to 2012. At least 49.6% of participants (range: 49.6%-78.9%) had increased post-workshop ratings (sign test; p < 0.001) for all level of comfort items with and understanding of core DMCA concepts. CONCLUSION: There is a need for DMCA training for physicians and HCPs. The content and method of the workshops are effective at enhancing self-reported level of comfort with and understanding of core DMCA concepts.

Improving transitions from acute care to home among complex older adults using the LACE Index and care coordination.

BACKGROUND: Improving transitions in care is a major focus of healthcare planning. The objective of this study was to determine the improvement in transitions from an intervention identifying complex older adult patients in acute care and supporting their discharge into the community. METHODS: This was a quality assurance study evaluating an intervention on high-risk patients admitted in an acute care hospital. In phase 1, the Length of Stay, Acuity of the Admission, Charlson Comorbidity Index Score, and Emergency Department Use (LACE Index) was selected to assess a patient's risk for readmission and a standard discharge protocol was developed. In phase 2, the intervention was implemented: (1) all patients were screened for the risk of readmission using the LACE Index; and (2) the high-risk patients were provided care coordination including follow-up phone calls focused on medications, equipment and homecare services. Emergency department (ED) revisits and hospital readmissions were measured. RESULTS: The LACE Index identified 433/1621 (27%) patients at high risk for readmission. Care coordination was achieved within 72 hours in 79% of patients. The 433 high-risk patients receiving the intervention, compared with a group without intervention (n=231), had lower lengths of stay (12.7 days vs 16.6 days); similar 7-day ED revisits (10.6% vs 10.8%) and 30-day ED revisits (30.5% vs 33.3%); lower 90-day readmissions (39.3% vs 44.6%); and lower 6-month readmissions (50.9% vs 58.4%). The 7-day and 30-day readmissions were similar in both groups. CONCLUSIONS: Identifying complex patients at high risk for readmission and supporting them during transitions from acute care to home potentially decreases lengths of hospital stay and prevents short-term ED revisits and long-term readmissions.

Deprescribing benzodiazepines among hospitalised older adults: quality improvement initiative.

Benzodiazepines are recognised as being potentially inappropriate medications for seniors due to their considerable side-effect profile, yet they are commonly prescribed and infrequently discontinued (deprescribed). The study's primary objective was the deprescription or the dose reduction of benzodiazepines among newly hospitalised seniors using a patient education intervention. A 3-month duration quality improvement study based on the plan-do-study-act model was conducted across two units (3C and 4D) in the Glenrose Rehabilitation Hospital to improve benzodiazepine deprescribing among newly admitted seniors (65 years or older) who were using benzodiazepines. The primary outcome measure was the number of eligible patients who had benzodiazepine deprescribing initiated. A patient education intervention comprising a structured medication review, written patient education (the Eliminating Medications Through Patient Ownership of End Results (EMPOWER) brochure) and at least one brief supportive counselling session by the clinical pharmacist or physician was applied to all eligible patients. All 12 eligible patients consented to benzodiazepine deprescribing; however, only 11 of them (92%) initiated benzodiazepine deprescribing. Six of the 11 patients (55%) had their benzodiazepines discontinued, with the 5 remaining patients (45%) achieving greater than 50% dosage reduction. Seven patients (64%) experienced side effects during the deprescribing process, with over half (57%, n=4) of these seven patients experiencing worsening anxiety symptoms. Five of the 11 patients (45%) required benzodiazepine substitute medications. The use of a structured patient education intervention involving the use of a structured medication review, written patient education material and one-on-one patient counselling can promote benzodiazepine deprescribing. Although worsening anxiety was frequently observed, this was easily managed by the substitution of a more appropriate and clinically indicated medication, which was well tolerated and acceptable by all of our participants. Targeted screening for the presence of anxiety would help to guide the deprescribing process and the need for medication substitution.

Predicting Hepatic Encephalopathy-Related Hospitalizations Using a Composite Assessment of Cognitive Impairment and Frailty in 355 Patients With Cirrhosis.

INTRODUCTION: Hepatic encephalopathy (HE) is the most common potentially modifiable reason for admission in patients with cirrhosis. Cognitive and physical components of frailty have pathophysiologic rationale as risk factors for HE. We aimed to assess the utility of a composite score (MoCA-CFS) developed using the Montreal Cognitive Assessment (MoCA) and the Clinical Frailty Scale (CFS) for predicting HE admissions within 6 months. METHODS: Consecutive adult patients with cirrhosis were followed for 6 months or until death/transplant. Patients with overt HE and dementia were excluded. Primary outcome was the prediction of HE-related admissions at 6 months. RESULTS: A total of 355 patients were included; mean age 55.9 ± 9.6; 62.5% male; Hepatitis C and alcohol etiology in 64%. Thirty-six percent of patients had cognitive impairment according to the MoCA (≤24) and 14% were frail on the CFS (>4). The MoCA-CFS independently predicted HE hospitalization within 6 months, a MoCA-CFS score of 1 and 2 respectively increasing the odds of hospitalization by 3.3 (95% CI:1.5-7.7) and 5.7 (95% CI:1.9-17.3). HRQoL decreased with increasing MoCA-CFS. Depression and older age were independent predictors of a low MoCA. CONCLUSIONS: Cognitive and physical frailty are common in patients with cirrhosis. In addition to being an independent predictor of HE admissions within 6 months, the MoCA-CFS composite score predicts impaired HRQoL and all-cause admissions within 6 months. These data support the predictive value of a "multidimensional" frailty tool for the prediction of adverse clinical outcomes and highlight the potential for a multi-faceted approach to therapy targeting cognitive impairment, physical frailty and depression.

Secondary Hypertension: Discovering the Underlying Cause.

Most patients with hypertension have no clear etiology and are classified as having primary hypertension. However, 5% to 10% of these patients may have secondary hypertension, which indicates an underlying and potentially reversible cause. The prevalence and potential etiologies of secondary hypertension vary by age. The most common causes in children are renal parenchymal disease and coarctation of the aorta. In adults 65 years and older, atherosclerotic renal artery stenosis, renal failure, and hypothyroidism are common causes. Secondary hypertension should be considered in the presence of suggestive symptoms and signs, such as severe or resistant hypertension, age of onset younger than 30 years (especially before puberty), malignant or accelerated hypertension, and an acute rise in blood pressure from previously stable readings. Additionally, renovascular hypertension should be considered in patients with an increase in serum creatinine of at least 50% occurring within one week of initiating angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy; severe hypertension and a unilateral smaller kidney or difference in kidney size greater than 1.5 cm; or recurrent flash pulmonary edema. Other underlying causes of secondary hypertension include hyperaldosteronism, obstructive sleep apnea, pheochromocytoma, Cushing syndrome, thyroid disease, coarctation of the aorta, and use of certain medications.

Physician education on decision-making capacity assessment: Current state and future directions.

OBJECTIVE: To examine FPs' training needs for conducting decision-making capacity assessments (DMCAs) and to determine how training materials, based on a DMCA model, can be adapted for use by FPs. DESIGN: A scoping review of the literature and qualitative research methodology (focus groups and structured interviews). SETTING: Edmonton, Alta. PARTICIPANTS: Nine FPs, who practised in various settings, who chose to attend a focus group on DMCAs. METHODS: A scoping review of the literature to examine the current status of physician education regarding assessment of decision-making capacity, and a focus group and interviews with FPs to ascertain the educational needs of FPs in this area. MAIN FINDINGS: Based on the scoping review of the literature, 4 main themes emerged: increasing saliency of DMCAs owing to an aging population, suboptimal DMCA training for physicians, inconsistent approaches to DMCA, and tension between autonomy and protection. The findings of the focus groups and interviews indicate that, while FPs working as independent practitioners or with interprofessional teams are motivated to engage in DMCAs and use the DMCA model for those assessments, several factors impede their conducting DMCAs. The most notable barriers were a lack of education, isolation from interprofessional teams, uneasiness around managing conflict with families, fear of liability, and concerns regarding remuneration. CONCLUSION: This pilot study has helped to inform ways to better train and support FPs in conducting DMCAs. Family physicians are well positioned, with proper training, to effectively conduct DMCAs. To engage FPs in the process, however, the barriers should be addressed.

Prevalence and predictors of booster seat use in Alberta, Canada.

OBJECTIVE: To determine the prevalence of booster seat misuse in a Canadian province and identify determinants of non-use. METHODS: A cross-sectional study using parking lot interviews and in-vehicle restraint inspections by trained staff was conducted at 67 randomly selected childcare centres across Alberta. Only booster-eligible children were included in this analysis. Odds ratios (OR) and 95% confidence intervals (CI) are reported using unadjusted and adjusted logistic regression. RESULTS: Overall, 23% of children were not in a booster seat, and in 31.8% of cases there was evidence of at least one misuse. Non-use increased significantly by age, from 22.2% for children 2 years of age to 47.8% for children 7 years of age (p = 0.02). Children who were at significantly increased risk of booster seat non-use were those in vehicles with drivers who could not recall the booster seat to seatbelt transition point (OR: 4.54; 95% CI: 2.05-10.06) or drivers who were under the age of 30 (OR: 3.54; 95% CI: 1.45-8.62). A front row seating position was also associated with significantly higher risk of nonuse (OR: 18.00; 95% CI: 2.78-116.56). Children in vehicles with grandparent drivers exhibited significantly decreased risk of booster seat non-use (OR: 0.21; 95% CI: 0.05-0.85). CONCLUSION: Messaging should continue to stress that the front seat is not a safe place for any child under the age of 9 as well as remind drivers of the booster seat to seatbelt transition point, with additional emphasis placed on appealing to parents under the age of 30. Future research should focus on the most effective means of communicating booster seat information to this group. Enacting mandatory booster seat legislation would be an important step to increase both awareness and proper use of booster seats in Alberta.
