Effects of a Province-wide Triaging System for TIA: The ASPIRE Intervention.

BACKGROUND AND OBJECTIVES: Urgent transient ischemic attack (TIA) management to reduce stroke recurrence is challenging, particularly in rural and remote areas. In Alberta, Canada, despite an organized stroke system, data from 1999 to 2000 suggested that stroke recurrence after TIA was as high as 9.5% at 90 days. Our objective was to determine whether a multifaceted population-based intervention resulted in a reduction in recurrent stroke after TIA. METHODS: In this quasi-experimental health services research intervention study, we implemented a TIA management algorithm across the entire province, centered around a 24-hour physician's TIA hotline and public and health provider education on TIA. From administrative databases, we linked emergency department discharge abstracts to hospital discharge abstracts to identify incident TIAs and recurrent strokes at 90 days across a single payer system with validation of recurrent stroke events. The primary outcome was recurrent stroke; with a secondary composite outcome of recurrent stroke, acute coronary syndrome, and all-cause death. We used an interrupted time series regression analysis of age-adjusted and sex-adjusted stroke recurrence rates after TIA, incorporating a 2-year preimplementation period (2007-2009), a 15-month implementation period, and a 2-year postimplementation period (2010-2012). Logistic regression was used to examine outcomes that did not fit the time series model. RESULTS: We assessed 6,715 patients preimplementation and 6,956 patients postimplementation. The 90-day stroke recurrence rate in the pre-Alberta Stroke Prevention in TIA and mild Strokes (ASPIRE) period was 4.5% compared with 5.3% during the post-ASPIRE period. There was neither a step change (estimate 0.38; p = 0.65) nor slope change (parameter estimate 0.30; p = 0.12) in recurrent stroke rates associated with the ASPIRE intervention implementation period. Adjusted all-cause mortality (odds ratio 0.71, 95% CI 0.56-0.89) was significantly lower after the ASPIRE intervention. DISCUSSION: The ASPIRE TIA triaging and management interventions did not further reduce stroke recurrence in the context of an organized stroke system. The apparent lower mortality postintervention may be related to improved surveillance after events identified as TIAs, but secular trends cannot be excluded. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that a standardized population-wide algorithmic triage system for patients with TIA did not reduce recurrent stroke rate.

Cultural Knowledge in Context - People Aged 50 Years and Over Make Sense of a First Fracture and Osteoporosis.

Catch a Break (CaB) is a secondary fracture prevention program that uses medical understandings of osteoporosis to assess first fractures and determine appropriateness for secondary fracture prevention. In this study, we interviewed CaB program participants to identify the understandings that patients themselves used to make sense of first fractures and the osteoporosis suggestion as cause. Semi-structured interviews were conducted with female and male participants of the CaB program in Canada. An interpretive practice approach was used to analyze the data. A random sample of 20 individuals, 12 women, and eight men all aged 50 years and over participated. First fractures were produced as meaningful in the context of osteoporosis only for seniors of very advanced age, and for people of any age with poor nutrition. The trauma events that led to a first fracture were produced as meaningful only if perceived as accidents, and having an active lifestyle was produced as beneficial only for mental health and well-being unrelated to osteoporosis. Cultural knowledge shapes, but does not determine, how individuals make sense of their health and illness experiences. Risk prevention program designers should include patients on the design team and be more aware of the presumptive knowledge used to identify individuals at risk of disease.

Odontogenic carcinosarcoma - A rare case report with review of literature.

Odontogenic carcinosarcoma (OCS) is a rare malignant odontogenic tumor (OT) with only a few cases reported in the literature. Its synonyms are ameloblastic carcinosarcoma, malignant mixed OT. It is characterized by a true mixed tumor showing malignant cytology of both epithelial and mesenchymal components. The tumor invaded into adjacent tissues by destroying the bone. A 24-year-old patient visited the outpatient clinic of GITAM Dental College and Hospital, with a chief complaint of growth in the lower right back tooth region for 6 months. Based on clinical and radiographic features, it has been diagnosed as an aggressive central jaw lesion. The patient was further referred for histological examination for confirmatory diagnosis. It has been diagnosed as an adenomatoid OT. The OCS most commonly affects the posterior part of the mandible. A larger number of cases were reported recently, and prolonged follow-up is needed to further clarify the nature of OCS.

Brown tumor of hyperparathyroidism with multiple lesions.

Brown tumors are rare focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone (PTH) on bone tissue in some patients with hyperparathyroidism. Browns tumor is a syndrome associated with an increase in PTH levels by parathyroid glands resulting in hypercalcemia. In the present case report, a 44-year-old female patient presented with a rare case of brown tumor with multiple lesions in the head-and-neck region. The recent advance in various diagnostic and biochemical tests helps in early diagnosis of hyperparathyroidism cases. The dentist should be aware of oral manifestations associated with this type of systemic disease.

Accounts of health risk assessment survey administration in the Catch a Break Program: the social construction of osteoporosis risk identification and need for intervention.

Catch a Break staff conducting the organizational work of delivering secondary fracture prevention screening conversations drew on cultural and organizational resources to determine eligibility of individuals. They encountered and navigated their way through interactional troubles as they requested participation, assessed trauma risk, and provided lifestyle information. PURPOSE: We investigated delivery of a population-based type C fracture liaison service for non-hip fractures. The purpose of this study was to examine accounts of how osteoporosis health risk screening interactions were delivered. METHODS: A pre-determined sample of 5 organizational representatives (program staff) were interviewed by telephone. We analyzed the qualitative data through the lens of interpretive inquiry, informed by discourse analysis, to examine staff's "talk" about conducting the program risk screening conversations. RESULTS: A dominant finding emerging from CAB staff's accounts of program delivery was the conversational work required to include only those individuals deemed appropriate for the program while managing the survey interaction. Staff talked about specific examples of interactional troubles they experienced as barriers to the smooth and successful risk screening conversation. They drew on cultural and organizational resources as interpretive frameworks to make decisions about individuals and groups at risk and in need of further investigation. They drew on larger ideas about ageism and genderism, judging as inappropriate for participation the oldest old adults, men involved in high risk occupations, and adults aged 50 to 70. Staff also employed interactional resources useful in managing problems in the conversation during the request to participate, trauma risk assessment, and lifestyle/health information provision sequences of the risk screening call. CONCLUSION: We uncovered areas in the screening interaction that were talked about by staff as problematic to achieving the program objective of identifying and enrolling individuals in the secondary fracture prevention program. By highlighting areas for improvement in program delivery, this study may help to reduce the interactional troubles staff negotiate as they deliver this type of program.

The predictive ability of EQ-5D-3L compared to the LACE index and its association with 30-day post-hospitalization outcomes.

PURPOSE: To examine whether the EQ-5D-3L at the time of discharge from hospital provides additional prognostic information above the LACE index for 30-day post-discharge hospital readmission and to explore the association of EQ-5D-3L with readmissions, emergency department (ED) visits, and death within the same period. METHODS: Using data (n = 495; mean age 62.9 years (SD 18.6), 50.5% female) from a prospective cohort study of patients discharged from medical wards at two university hospitals, the prognostic ability of EQ-5D-3L was examined using C-statistic, Integrated Discrimination Improvement (IDI) Index, and Akaike's Information Criterion (AIC). The associations between EQ-5D-3L dimensions, total sum, index and VAS scores at the time of discharge and 30-day post-discharge ED visits, readmission, and readmission/death were examined using multivariate logistic regression. RESULTS: At the time of discharge, 58.6% of participants reported problems in mobility, 28.3% in self-care, 62.1% in usual activities, 62.7% in pain/discomfort, and 42.4% in anxiety/depression. Mean (SD) total sum score was 7.9 (2.0), index score was 0.69 (0.21), and VAS score was 63.7 (18.4). In adjusted analyses, mobility, self-care, usual activities, and the total sum score were significantly associated with 30-day readmission and readmission/death. Differences in C-statistic for LACE readmission prediction models with and without EQ-5D-3L were small. AIC analysis suggests that readmission prediction models containing EQ-5D-3L dimensions or scores were more often preferred to those with the LACE index only. IDI analysis indicates that the discrimination slope of readmission prediction models is significantly improved with the addition of mobility, self-care, or the total sum score of the EQ-5D-3L. CONCLUSION: The EQ-5D-3L, especially the mobility and self-care dimensions as well as the total sum score, improves 30-day readmission prediction of the LACE index and is associated with 30-day readmissions or readmissions/death.

Cholesteatoma of Maxillary Sinus Simulating Neoplasia: A Rare Case Report.

The term cholesteatoma refers to "chole": cholesterol, "steat": fat and "oma,": "tumor". This tumor has been reported to be the most common in the middle ear. The occurrence of such a tumor in the maxillary sinus is deemed to be very rare and hardly 4 cases were reported in India and 26 cases described worldwide. This case report intends to discuss the uniqueness and indolent nature of this lesion in terms of histopathology and radiography.

Patients' Experiences of Nurse Case-Managed Osteoporosis Care: A Qualitative Study.

BACKGROUND: Osteoporosis is a chronic condition that is often left untreated. Nurse case-managers can double rates of appropriate treatment in those with new fractures. However, little is known about patients' experiences of a nurse case-managed approach to osteoporosis care. OBJECTIVE: Our aim was to describe patients' experiences of nurse case-managed osteoporosis care. METHODS: A qualitative, descriptive design was used. We recruited patients enrolled in a randomized controlled trial of a nurse case-management approach. Individual semi-structured interviews were conducted which were transcribed and analyzed using content analysis. Data were managed with ATLAS.ti version 7. RESULTS: We interviewed 15 female case-managed patients. Most (60%) were 60-years or older, 27% had previous fracture, 80% had low bone mineral density tests, and 87% had good osteoporosis knowledge. Three major themes emerged from our analysis: acceptable information to inform decision-making; reasonable and accessible care provided; and appropriate information to meet patient needs. CONCLUSIONS: This study provides important insights about older female patients' experiences with nurse case-managed care for osteoporosis. Our findings suggest that this model to osteoporosis clinical care should be sustained and expanded in this setting, if proven effective. In addition, our findings point to the importance of applying patient-centered care across all dimensions of quality to better enhance the patients' experience of their health care.

An Outreach Rehabilitation Program for Nursing Home Residents After Hip Fracture May Be Cost-Saving.

BACKGROUND: We compared the cost-effectiveness of 10 weeks of outreach rehabilitation (intervention) versus usual care (control) for ambulatory nursing home residents after hip fracture. METHODS: Enrollment occurred February 2011 through June 2015 in a Canadian metropolitan region. Seventy-seven participants were allocated in a 2:1 ratio to receive a 10-week rehabilitation program (intervention) or usual care (control) (46 intervention; 31 control). Using a payer perspective, we performed main and sensitivity analyses. Health outcome was measured by quality-adjusted life years (QALYs), using the EQ5D, completed at study entry, 3-, 6-, and 12-months. We obtained patient-specific data for outpatient visits, physician claims, and inpatient readmissions; the trial provided rehabilitation utilization/cost data. We estimated incremental cost and incremental effectiveness. RESULTS: Groups were similar at study entry; the mean age was 87.9 ± 6.6 years, 54 (71%) were female and 58 (75%) had severe cognitive impairment. EQ5D QALYs scores were nonsignificantly higher for intervention participants. Inpatient readmissions were two times higher among controls, with a cost difference of -$3,350/patient for intervention participants, offsetting the cost/intervention participant of $2,300 for the outreach rehabilitation. The adjusted incremental QALYs/patient difference was 0.024 favoring the intervention, with an incremental cost/patient of -$621 for intervention participants; these values were not statistically significant. A sensitivity analysis reinforced these findings, suggesting that the intervention was likely dominant. CONCLUSION: A 10-week outreach rehabilitation intervention for nursing home residents who sustain a hip fracture may be cost-saving, through reduced postfracture hospital readmissions. These results support further work to evaluate postfracture rehabilitation for nursing home residents.

Successful implementation of a Fracture Liaison Service through effective change management: a qualitative study.

We assessed the context in which a hip Fracture Liaison Service was implemented. We conducted semi-structured interviews with 21 key informants at two time points to understand organizational readiness, facilitators, and barriers to change. We identified strategies important to successful implementation, particularly in the context of change fatigue. PURPOSE: Fracture Liaison Service (FLS) is effective for secondary fracture prevention. Two hospital sites implemented FLS for hip fracture patients, 50 + years, in Alberta, Canada. We assessed organizational readiness, facilitators, and barriers to change to better understand the context in which the FLS was implemented to inform its potential spread provincially. METHODS: We recruited individuals involved in FLS implementation at provincial and site levels to participate in telephone interviews at baseline and 16 months post-implementation. Interviews were transcribed and analyzed using thematic content analysis. In addition, site-level participants were invited to complete the Organizational Readiness to Implement Change tool at baseline. RESULTS: We conducted 33 semi-structured interviews (20 at baseline; 13 at post-implementation) with 21 key informants. Participants included managers (24%), FLS physicians/clinical nurses (19%), operational/leadership roles (19%), physicians/surgeons (14%), pharmacists (10%), nurse practitioners (10%), and social work (5%). Seventeen site-level participants completed the ORIC tool at baseline; all participants scored high (71%) or neutral (29%). We found that the use of several strategies, including demonstrating value, providing resources, and selecting appropriate sites, were important to implementation, particularly in the context of change fatigue. Participants perceived the FLS as acceptable and there was evidence of facilitated learning rather than simply monitoring implementation as intended. CONCLUSIONS: An effective change management approach neutralized change fatigue. This approach, if maintained, bodes well for the potential spread of the FLS provincially if proven effective and cost effective. Change readiness assessment tools could be used strategically to inform the spread of the FLS to early adopter sites.

Pediatric intraosseous schwannoma in maxillary sinus: A case report with review of literature.

Neurilemmoma has been defined as a benign, encapsulated neoplasm that arises in the nerve fiber. It originates from the proliferation of Schwann cells in the perineurium causing displacement and compression of the adjacent nerve. This neoplasm is composed primarily of Schwann cells in a poorly collagenized stroma. It can occur in any age group. Neurilemmoma occurs all over the body including the head and neck region. In the head and neck region, 25%-40% of schwannoma cases have been reported. Occurrences of intraoral schwannomas are rare with reported prevalence being 1%. In the present article, we report a case of a 19-month-old baby complaining of pain and swelling. On clinical, radiological and histopathological features it was diagnosed as pediatric intraosseous schwannoma of the maxillary sinus.

Evaluation of immunomorphological patterns of cervical lymph nodes in oral squamous cell carcinoma.

BACKGROUND: The Immunomorphological patterns of Lymph Nodes indirectly assess the host immune response facing a malignant tumor. These patterns also help us predict the susceptibility of the patient to Lymph Node Metastasis. AIMS AND OBJECTIVES: To evaluate the Immunomorphological patterns of Lymph Nodes in Oral Squamous Cell Carcinoma and to correlate them with the histopathological subtype of Oral Squamous Cell Carcinoma, TNM staging and the degree of tumor involvement within the Lymph Nodes. METHODOLOGY: A total of 40 subjects were taken for the study. Individuals who were clinically and histopathologically diagnosed as cases of Squamous Cell Carcinoma, who had undergone Radical or Elective Neck dissection were considered. The excised Lymph Nodes along with the primary tumor were collected stained with Hematoxylin and Eosin. The Lymph Nodes were assessed for Metastasis and Immunomorphological patterns. Statistical Correlation was done between the Immunomorphological pattern of Lymph Nodes and (a) Size of the tumor, (b) TNM stage of the tumor, (c) Histopathological Grade of the primary tumor, (d) Metastasis of the Lymph Node and (e) Grade of the Metastasis of Lymph Node. Statistical Correlation was done between the Metastasis of the Lymph Node and (a) Size of the tumor and (b) TNM stage of the tumor. RESULTS AND CONCLUSION: Statistically, a significant association was observed between TNM staging and Immunomorphological patterns of Lymph Node (P < 0.01). The relationship between histopathological grade of primary tumor of Squamous Cell Carcinoma and the Immunomorphological patterns was statistically significant (P < 0.01). Statistically, a significant association was observed between Sinus Histiocytosis pattern and decreased occurrence of nodal metastasis (P < 0.01).

Evaluation of genotoxicity by micronucleus assay in oral leukoplakia and oral squamous cell carcinoma with deleterious habits.

BACKGROUND: Oral cancer is the 12th most common cancer in women and the 6th in men. Of all oral malignancies, more than 92-95% is Oral Squamous Cell Carcinoma (OSCC). The high risk was due to Lifestyle-related habits such as smoking, alcohol consumption, chewing of areca nut related products which are considered as the major risk factors in OSCC. The exogenous carcinogens from tobacco smoke may induce a defective DNA damage response, which may alter the expression of genes that protect us against cancer that may result in genomic instability and this DNA damage can be assessed by studying the chromosomal aberrations, sister chromatid exchanges and the varied forms of the micronucleus. AIMS AND OBJECTIVES: The aim of this study was to evaluate the risk of development of oral leukoplakia (OLP) and OSCC due to DNA damage by studying micronuclei count in the east coast of Andhra Pradesh population with tobacco consumption habit and habit-free controls using Fluorescent microscopy. MATERIALS AND METHODS: A total of 60 subjects, 20 normal controls, 20 oral leukoplakia and 20 OSCC patients were selected from the outpatient patients of GITAM Dental College and Hospital, Rushikonda, Visakhapatnam and peripheral cancer hospitals in and around Visakhapatnam. Exfoliated cells were collected by giving 5-6 gentle strokes with spatula in a continuous unidirectional movement and then were uniformly spread on the previously cleaned microscopic slide. Fluorescent stain 4', 6'-diamidino-2 phenylindole (DAPI) was used for MN analysis. RESULTS: Mean of cells with MN in controls, leukoplakia and OSCC cases was observed to be 1, 5.1,10.1 (F = 112.396, P < 0.001) respectively. Mean of the cells with MN in different grades of leukoplakia. (F = 35.594, P < 0.001) Mean of the cells with MN in different grades of OSCC. (F = 39.752, P < 0.001). CONCLUSION: The present study revealed an increase in mean frequency of cells with micronucleus from healthy individuals however similar studies in larger sample has to be done. This study concludes that MN index can be used as a screening test among high risk groups.

Lymphoma in an extraction socket.

Non-Hodgkin's lymphoma (NHL) is a lymphoproliferative malignancy that can involve both lymph node and lymphoid organs as well as extranodal organs and tissues. The aim of presenting this case of NHL is to highlight the suspicion of its occurrence in the region of unhealed extraction sockets and the significance of its awareness. NHL can be presented in various forms; therefore, a thorough knowledge regarding this malignancy is essential for arriving at the earliest possible diagnosis and therapy for the patient.

Impact of a household-level deductible on prescription drug use among lower-income adults: a quasi-experimental study.

BACKGROUND: Several Canadian public drug plans have income-based deductibles, but we have limited data on their impact, particularly for vulnerable populations. Therefore, we studied the impact of deductibles in British Columbia's Fair PharmaCare program on drug use among lower-income adults. METHODS: We used a quasi-experimental regression discontinuity design to study the impact of BC rules that impose no deductible before receiving public coverage on households with incomes less than $15 000, a deductible of 2% of household income on those with incomes between $15 000 and $30 000, and a deductible of 3% of household income on those with incomes above $30 000. We studied the impact of these thresholds on public and total drug expenditures between 2003 and 2015 using 24 million person-years of data. RESULTS: Both thresholds decreased the proportion of beneficiaries receiving benefits, by 0.33 (95% confidence interval [CI] -0.34 to -0.30) and 0.05 (95% CI -0.064 to -0.032) respectively. There were also substantial reductions in the extent of public drug plan expenditures ($59.94 [95% CI -74.74 to -45.14] and $26.12 [95% CI -39.78 to -12.46], respectively). The change at the $15 000 threshold reduced patient drug expenditures by $26.00 (95% CI -45.48 to -6.51), or 7.2%. In contrast, we found no statistically significant change in total expenditures when households moved from a deductible of 2% to 3% at the $30 000 threshold. INTERPRETATION: Income-based deductibles considerably affected the extent of public subsidy for prescription drugs. For lower-income households making around $15 000, the deductible led to a reduction of 7.2% in overall drug use and costs. Although deductibles are a useful tool to limit public expenditures, policy-makers should be cautious in their use among vulnerable populations.

Quality improvement strategies to prevent falls in older adults: a systematic review and network meta-analysis.

BACKGROUND: Falls are a common occurrence and the most effective quality improvement (QI) strategies remain unclear. METHODS: We conducted a systematic review and network meta-analysis (NMA) to elucidate effective quality improvement (QI) strategies for falls prevention. Multiple databases were searched (inception-April 2017). We included randomised controlled trials (RCTs) of falls prevention QI strategies for participants aged ≥65 years. Two investigators screened titles and abstracts, full-text articles, conducted data abstraction and appraised risk of bias independently. RESULTS: A total of 126 RCTs including 84,307 participants were included after screening 10,650 titles and abstracts and 1210 full-text articles. NMA including 29 RCTs and 26,326 patients found that team changes was statistically superior in reducing the risk of injurious falls relative to usual care (odds ratio [OR] 0.57 [0.33 to 0.99]; absolute risk difference [ARD] -0.11 [95% CI, -0.18 to -0.002]). NMA for the outcome of number of fallers including 61 RCTs and 40 128 patients found that combined case management, patient reminders and staff education (OR 0.18 [0.07 to 0.47]; ARD -0.27 [95% CI, -0.33 to -0.15]) and combined case management and patient reminders (OR, 0.36 [0.13 to 0.97]; ARD -0.19 [95% CI, -0.30 to -0.01]) were both statistically superior compared to usual care. CONCLUSIONS: Team changes may reduce risk of injurious falls and a combination of case management, patient reminders, and staff education, as well as case management and patient reminders may reduce risk of falls. Our results can be tailored to decision-maker preferences and availability of resources. SYSTEMATIC REVIEW REGISTRATION: PROSPERO (CRD42013004151).

Cost-Effectiveness of Osteoporosis Interventions to Improve Quality of Care After Upper Extremity Fracture: Results From a Randomized Trial (C-STOP Trial).

We assessed the cost-effectiveness of two models of osteoporosis care after upper extremity fragility fracture using a high-intensity Fracture Liaison Service (FLS) Case-Manager intervention versus a low-intensity FLS (ie, Active Control), and both relative to usual care. This analysis used data from a pragmatic patient-level parallel-arm comparative effectiveness trial of 361 community-dwelling participants 50 years or older with upper extremity fractures undertaken at a Canadian academic hospital. We used a decision-analytic Markov model to evaluate the cost-effectiveness of the three treatment alternatives. The perspective was health service payer; the analytical horizon was lifetime; costs and health outcomes were discounted by 3%. Costs were expressed in 2016 Canadian dollars (CAD) and the health effect was measured by quality adjusted life years (QALYs). The average age of enrolled patients was 63 years and 89% were female. Per patient cost of the Case Manager and Active Control interventions were $66CAD and $18CAD, respectively. Compared to the Active Control, the Case Manager saved $333,000, gained seven QALYs, and averted nine additional fractures per 1000 patients. Compared to usual care, the Case Manager saved $564,000, gained 14 QALYs, and incurred 18 fewer fractures per 1000 patients, whereas the Active Control saved $231,000, gained seven QALYs, and incurred nine fewer fractures per 1000 patients. Although both interventions dominated usual care, the Case Manager intervention also dominated the Active Control. In 5000 probabilistic simulations, the probability that the Case Manager intervention was cost-effective was greater than 75% whereas the Active Control intervention was cost-effective in less than 20% of simulations. In summary, although the adoption of either of these approaches into clinical settings should lead to cost savings, reduced fractures, and increased quality-adjusted life for older adults following upper extremity fracture, the Case Manager intervention would be the most likely to be cost-effective. © 2019 American Society for Bone and Mineral Research.

Rehabilitation After Hip Fracture for Nursing Home Residents: A Controlled Feasibility Trial.

BACKGROUND: This study compared functional outcomes at 3 months after hip fracture surgery between nursing home residents participating in a 10-week outreach rehabilitation program and those receiving usual care. Function, health-related quality of life, and mortality were also compared over 12 months, and outreach program feasibility was assessed. METHODS: A feasibility trial was undertaken in Canadian nursing homes; of 77 participants, 46 were allocated to Outreach and 31 to Control prior to assessing function or cognition. Outreach participants received 10 weeks of rehabilitation (30 sessions), and Control participants received usual posthospital fracture care in their nursing homes. The primary outcome was the Functional Independence Measure Physical Domain (FIMphysical) score 3 months post-fracture; we also explored FIM Locomotion and Mobility. Secondary outcomes were FIM scores, EQ-5D-3L scores, and mortality over 12 months. Program feasibility was also evaluated. RESULTS: The mean age was 88.7 ± 7.0 years, 55 (71%) were female, and 58 (75%) had severe cognitive impairment with no significant group differences (p > .14). Outreach participants had significantly higher FIM Locomotion than usual care (p = .02), but no significant group differences were seen in FIMphysical or FIM Mobility score 3 months post-fracture. In adjusted analyses, Outreach participants reported significant improvements in all FIM and EQ-5D-3L scores compared with Control participants over 12 months (p < .05). Mortality did not differ by group (p = .80). Thirty (65%) Outreach participants completed the program. CONCLUSIONS: Our feasibility trial demonstrated that Outreach participants achieved better locomotion by 3 months post-fracture compared with participants receiving usual postfracture care; benefits were sustained to 12 months post-fracture. In adjusted analyses, Outreach participants also showed sustained benefits in physical function and health-related quality of life.

Changes in employer-sponsored private health insurance among retirees in Ontario: a cross-sectional study.

BACKGROUND: Employer-sponsored health insurance, particularly for retirees with limited incomes, plays a major funding role in Canadian health care, including prescription drugs and dental services. We aimed to investigate the changes in retiree health insurance availability over time. METHODS: We performed a secondary analysis of data from the 2005 and 2013-2014 cycles of the Canadian Community Health Survey using multivariate logistic regression to study changes in retiree coverage availability over time in Ontario. We estimated the adjusted odds ratios of having employer coverage for likely retirees (people over age 65 yr who reported not working and those over age 75 yr), adjusting for a number of potential confounders. Sensitivity analysis was also performed for coverage of different treatments separately. RESULTS: The response rate was 76% for the 2005 cycle and 66% for 2013-2014 for the entire survey. The characteristics of respondents in the 2 survey cycles were similar, except respondents in 2013-2014 were wealthier. In our adjusted model, respondents in 2013-2014 had lower odds of reporting retiree coverage than respondents in 2005 (adjusted odds ratio 0.87; 95% confidence interval 0.77-0.99). This represents an absolute reduction in the probability of receiving retiree coverage of up to 3.4%. INTERPRETATION: Our analysis suggests that the rate of retiree health insurance has declined for Canadians with similar characteristics over the past decade. As we know insurance coverage has a strong association with use of treatments such as prescription drugs and dental care, this decline may result in decreased access to treatment and is an issue that warrants further investigation.

Blood pressure reduction in hypertensive acute ischemic stroke patients does not affect cerebral blood flow.

The effect of blood pressure (BP) reduction on cerebral blood flow (CBF) in acute ischemic stroke is unknown. We measured regional CBF with perfusion-weighted MRI before and after BP treatment in a three-armed non-randomized prospective controlled trial. Treatment arm assignment was based on acute mean arterial pressure (MAP). Patients with (MAP) >120 mmHg (n = 14) were treated with intravenous labetalol and sublingual (SL) nitroglycerin (labetalol group). Those with MAP 100-120 mmHg (n = 17) were treated with SL nitroglycerin (0.3 mg) ('NTG Group') and those with baseline MAP<100 mmHg (n = 18) were not treated with antihypertensive drugs (untreated group). Forty-nine patients (18 female, mean age 65.3 ± 12.9 years) were serially imaged. Labetalol reduced MAP by 12.5 (5.7-17.7) mmHg, p = 0.0002. MAP remained stable in the NTG (6.0 (0.4-16, p = 0.3) mmHg and untreated groups (-0.3 (-2.3-7.0, p = 0.2) mmHg. The volume of total hypoperfused tissue (CBF<18 ml/100 g/min) did not increase after labetalol (-1.1 ((-6.5)-(-0.2)) ml, p = 0.1), NTG (0 ((-1.5)-4.5) ml, p = 0.72), or no treatment 0.25 ((-10.1)-4.5) ml, p = 0.87). Antihypertensive therapy, based on presenting BP, in acute stroke patients was not associated with an increased volume of total hypoperfused tissue.
