PurposeOnline programs may help to engage patients in advance care planning in outpatient settings. We sought to implement an online advance care planning program, PREPARE (Prepare for Your Care; http://www.prepareforyourcare.org), at home and evaluate the changes in advance care planning engagement among patients attending outpatient clinics.MethodsWe undertook a prospective before-and-after study in 15 primary care clinics and 2 outpatient cancer centers in Canada. Patients were aged 50 years or older (primary care) or 18 years or older (cancer care) and free of cognitive impairment. They used the PREPARE website over 6 weeks, with reminders sent at 2 or 4 weeks. We used the 55-item Advance Care Planning Engagement Survey, which measures behavior change processes (knowledge, contemplation, self-efficacy, readiness) on 5-point scales and actions relating to substitute decision makers, quality of life, flexibility for the decision maker, and asking doctors questions on an overall scale from 0 to 21; higher scores indicate greater engagement.ResultsIn total, 315 patients were screened and 172 enrolled, of whom 75% completed the study (mean age = 65.6 years, 51% female, 35% had cancer). The mean behavior change process score was 2.9 (SD 0.8) at baseline and 3.5 (SD 0.8) at follow-up (mean change = 0.6; 95% CI, 0.49-0.73); the mean action measure score was 4.0 (SD 4.9) at baseline and 5.2 (SD 5.4) at follow-up (mean change = 1.2; 95% CI, 0.54-1.77). The effect size was moderate (0.75) for the former and small (0.23) for the latter. Findings were similar in both primary care and cancer care populations.ConclusionsImplementation of the online PREPARE program in primary care and cancer care clinics increased advance care planning engagement among patients.

ObjectivesTo assess the feasibility, acceptability and clinical sensibility of a novel survey, the advance care planning (ACP) Engagement Survey, in various healthcare settings.SettingA target sample of 50 patients from each of primary care, hospital, cancer care and dialysis care settings.ParticipantsA convenience sample of patients without cognitive impairment who could speak and read English was recruited. Patients 50 and older were eligible in primary care; patients 80 and older or 55 and older with clinical markers of advanced chronic disease were recruited in hospital; patients aged 19 and older were recruited in cancer and renal dialysis centres.OutcomesWe assessed feasibility, acceptability and clinical sensibility of the ACP Engagement Survey using a 6-point scale. The ACP Engagement Survey measures ACP processes (knowledge, contemplation, self-efficacy and readiness) on 5-point Likert scales and actions (yes/no).Results196 patients (38-96 years old, 50.5% women) participated. Mean (±SD) time to administer was 48.8±19.6 min. Mean acceptability scores ranged from 3.2±1.3 in hospital to 4.7±0.9 in primary care, and mean relevance ranged from 3.5±1.0 in hospital to 4.9±0.9 in dialysis centres (p

The quantitative analysis of sham feeding data based on curve shifts was utilized to evaluate the effects of various treatments on the intake of sweet solutions. The curve-shift paradigm provided approximately equal percentage suppressions of maximal intake during the analysis of five treatments for sham feeding data. Furthermore, quantitative data from the curve shift paradigm indicated the influence of sham treatments on the position of the concentration-sham intake curve in the x-axis.

Abstract Background The purpose of this study was to examine the relationship between the Medical Outcomes Study-HIV Health Survey (MOS-HIV) and the SF-12v2 to determine if the latter is adequate to assess the health-related quality of life (HRQoL) of men and women living with HIV/AIDS. 112 men and women living with HIV/AIDS who access care at a tertiary HIV clinic in Hamilton, Ontario were included in this cross-sectional analysis. Correlation coefficients of the MOS-HIV physical and mental health summary scores (PHS and MHS) and the SF-12v2 physical and mental component summary scales (PCS and MCS) were calculated along with common sub-domains of the measures including physical functioning (PF), bodily pain (BP), general health perceptions (GH), vitality (VT), social functioning (SF) and mental health (MH) to explore the relationship between these two HRQoL measures. The sub-domains role physical (RP) and role emotional (RE) of the SF-12v2 were compared separately to the sub-domain role functioning (RF) of the MOS-HIV. Weighted kappa scores were calculated to determine agreement beyond chance between the MOS-HIV and SF-12v2 in assigning a HRQoL state (i.e. low, moderate, good, very good). Results The MOS-HIV had mean PHS and MHS summary scores of 47.3 (SD = 11.5) and 49.2 (SD = 10.7) respectively. The mean SF-12v2 PCS and MCS scores were 47.7 (SD = 11.0) and 44.0 (SD = 10.4). The MOS-HIV and SF-12v2 physical and mental health summary scores were positively correlated (r = 0.84, p < 0.001 and r = 0.76, p < 0.001). All common sub-domains were significantly correlated at p values from < 0.001 to 0.034. Substantial agreement was observed in assigning a HRQoL state (Physical: κ = 0.788, SE = 0.095; Mental: κ = 0.707, SE = 0.095). Conclusions This analysis validates the SF-12v2 for measuring HRQoL in adult men and women living with HIV/AIDS.

Abstract Background Non-invasive surrogate measures which are valid and responsive to change are needed to study cardiovascular risks in HIV. We compared the construct validity of two noninvasive arterial measures: carotid intima medial thickness (IMT), which measures anatomic disease; and brachial flow-mediated vasodilation (FMD), a measure of endothelial dysfunction. Methods A sample of 257 subjects aged 35 years or older, attending clinics in five Canadian centres, were prospectively recruited into a study of cardiovascular risk among HIV subjects. The relationship between baseline IMT or FMD and traditional vascular risk factors was studied using regression analysis. We analyzed the relationship between progression of IMT or FMD and risk factors using fixed-effects models. We adjusted for use of statin medication and CD4 count in both models. Results Baseline IMT was significantly associated with age (p < 0.001), male gender (p = 0.034), current smoking status (p < 0.001), systolic blood pressure (p < 0.001) and total:HDL cholesterol ratio (p = 0.004), but not statin use (p = 0.904) and CD4 count (p = 0.929). IMT progression was significantly associated with age (p < 0.001), male gender (p = 0.0051) and current smoking status (p = 0.011), but not statin use (p = 0.289) and CD4 count (p = 0.927). FMD progression was significantly associated with current statin use (p = 0.019), but not CD4 count (p = 0.84). Neither extent nor progression of FMD was significantly associated with any of the examined vascular risk factors. Conclusion IMT correlates better than FMD with established cardiovascular risk factors in this cohort of HIV patients. Standardization of protocols for FMD and IMT will facilitate the comparison of results across studies.

Background: People who engage in advance care planning (ACP) are more likely to receive health care that is concordant with their goals at the end of life. Little discussion of ACP occurs in primary care.Objective: The objective of this study was to describe primary care clinicians' perspectives on having ACP conversations with their patients.Methods: We conducted a survey of family physicians and non-physician clinicians in primary care in 2014-2015. We compared family physicians and non-physician clinicians on willingness, confidence, participation and acceptability for other clinicians to engage in six aspects of ACP (initiating, exchanging information, decision coaching, finalizing plans, helping communicate plans with family members and other health professionals) on scales from 0 = not at all/extremely unacceptable to 6 = very/all the time/extremely acceptable.Results: The response rate was 72% (n = 117) among family physicians and 69% (n = 64) among non-physician clinicians. Mean ratings (standard deviation [SD]) of willingness were high (4.5 [1.4] to 5.0 [1.2] for physicians; 3.4 [1.8] to 4.6 [1.6] non-physician clinicians). There was little participation (mean ratings 2.4 [1.7] to 2.7 [1.6] for physicians, 1.0 [1.5] to 1.4 [1.7] for non-physician clinicians). Non-physician clinicians rated confidence statistically significantly lower than physicians for all ACP aspects. Acceptability for non-physician clinician involvement was high in both groups (mean acceptability ratings greater than 4).Conclusion: Current engagement of primary care clinicians in ACP is low. Given the high willingness and acceptability for non-physician clinician involvement, increasing the capacity of non-physician clinicians could enable uptake of ACP in primary care.

Infant feeding raises unique concerns for mothers living with HIV in Canada, where they are recommended to avoid breastfeeding yet live in a social context of 'breast is best.' In narrative interviews with HIV-positive mothers from Ontario, Canada, a range of feelings regarding not breastfeeding was expressed, balancing feelings of loss and self-blame with the view of responsibility and 'good mothering' under the current Canadian guidelines. Acknowledging responsibility to put their child's health first, participants revealed that their choices were influenced by variations in social and cultural norms, messaging, and guidelines regarding breastfeeding across geographical contexts. This qualitative study raises key questions about the impact of breastfeeding messaging and guidelines for HIV-positive women in Canada. [ABSTRACT FROM AUTHOR]

The prevalence of smoking in HIV-infected subjects is high. As a smoking cessation aid, varenicline (Champix®, Pfizer, Saint-Laurent, QC, Canada or Chantix®, Pfizer, Mission, KS) has not been previously evaluated in HIV-infected smokers. In this multicenter pilot open label study, varenicline 1.0 mg was used twice daily for 12 weeks with dose titration in the first week. Adverse events (AEs) during the treatment period were recorded. Changes from baseline in laboratory tests, vital signs, daily cigarette consumption, nicotine dependence, and withdrawal were measured through week 24. Self-reported abstinence was validated by serum cotinine at week 12. We enrolled 36 subjects with a mean of 29 pack-years of smoking and a minimum of 4 cigarettes per day. All but 1 were male, 33 (92%) were white. The most frequently reported AEs were nausea (33%), abnormal dreams (31%), affect lability (19%), and insomnia (19%). Six (17%) subjects discontinued varenicline due to AEs. No grade 3/4 laboratory abnormalities or serious AEs occurred during the study. There was no significant change in HIV viral load. CD4 counts increased by 69 cells/mm3 ( p=0.001) at week 24. Serum cotinine-verified 4-week continuous abstinence rate through weeks 9-12 was 42% (95% confidence interval [CI]: 26-58%). AEs and abstinence rates were comparable to those in published randomized controlled trials conducted in generally healthy HIV-negative smokers. Varenicline was safe and appears effective among HIV-infected smokers in this exploratory study, although AEs were common. The most common AE was nausea, with no adverse effect on HIV treatment outcome. Close monitoring of liver enzymes and blood pressure is recommended for HIV-positive smokers taking varenicline.

Objective: To identify barriers to and enablers of advance care planning (ACP) perceived by physicians and other health professionals in primary care., Design: Cross-sectional, self-administered survey., Setting: Ontario, Alberta, and British Columbia., Participants: Family physicians (n = 117) and other health professionals (n = 64) in primary care., Main Outcome Measures: Perceived barriers relating to the clinician, characteristics of patients, and system factors, rated on a 7-point scale from 0 (not at all) to 6 (an extreme amount), and enablers reported using an open-ended question., Results: Between November 2014 and June 2015, questionnaires were returned by 72.2% (117 of 162) of family physicians and 68.8% (64 of 93) of the other health professionals. Physicians rated insufficient time, inability to electronically transfer the advance care plan across care settings, decreased interaction with patients near the end of life owing to transfer of care, and patients' difficulty understanding limitations and complications of treatment options as the highest barriers. Other health professionals additionally identified their own lack of knowledge and difficulty accessing the physician as barriers. Themes identified as enablers included greater public engagement, clinician attitudes, creating capacity for clinicians, integrating ACP into practice, and system and policy supports., Conclusion: In primary care, there are barriers to engaging patients in ACP at the patient, provider, and system levels that could potentially be addressed through the informed development of multifaceted interventions., (Copyright© the College of Family Physicians of Canada.)
