ObjectivesPatient Global Rating of Change (GRC) scales are commonly used in routine clinical care given their ease of use, availability and short completion time. This analysis aimed at assessing the validity of Patient Global Impression of Change (PGIC), a GRC scale commonly used in fibromyalgia, in a Canadian real-life setting.Methods167 fibromyalgia patients with available PGIC data were recruited in 2005–2013 from a Canadian tertiary-care multidisciplinary clinic. In addition to PGIC, disease severity was assessed with: pain visual analogue scale (VAS); Patient Global Assessment (PGA); Fibromyalgia Impact Questionnaire (FIQ); Health Assessment Questionnaire (HAQ); McGill Pain Questionnaire; body map. Multivariate linear regression assessed the PGIC relationship with disease parameter improvement while adjusting for follow-up duration and baseline parameter levels. The Spearman's rank coefficient assessed parameter correlation.ResultsHigher PGIC scores were significantly (p<0.001) associated with greater improvement in pain, PGA, FIQ, HAQ and the body map. A statistically significant moderate positive correlation was observed between PGIC and FIQ improvement (r=0.423; p<0.001); correlation with all remaining disease severity measures was weak. Regression analysis confirmed a significant (p<0.001) positive association between improvement in all disease severity measures and PGIC. Baseline disease severity and follow-up duration were identified as significant independent predictors of PGIC rating.ConclusionsDespite that only a weak correlation was identified between PGIC and standard fibromyalgia outcomes improvement, in the absence of objective outcomes, PGIC remains a clinically relevant tool to assess perceived impact of disease management. However, our analysis suggests that outcome measures data should not be considered in isolation but, within the global clinical context.
Cannabinoids may hold potential for the management of rheumatic pain. Arthritis, often self-reported, is commonly cited as the reason for the use of medicinal herbal cannabis (marijuana). We have examined the prevalence of marijuana use among 1000 consecutive rheumatology patients with a rheumatologist-confirmed diagnosis and compared in an exploratory manner the clinical characteristics of medicinal users and nonusers. Current marijuana use, medicinal or recreational, was reported by 38 patients (3.8%; 95% CI: 2.8-5.2). Ever use of marijuana for medical purposes was reported by 4.3% (95% CI: 3.2-5.7), with 28 (2.8%; 95% CI: 1.9-4.0) reporting current medicinal use. Current medicinal users had a spectrum of rheumatic conditions, with over half diagnosed with osteoarthritis. Medicinal users were younger, more likely unemployed or disabled, and reported poorer global health. Pain report and opioid use was greater for users, but they had similar physician global assessment of disease status compared with nonusers. Medicinal users were more likely previous recreational users, with approximately 40% reporting concurrent recreational use. Therefore, less than 3% of rheumatology patients reported current use of medicinal marijuana. This low rate of use in patients with a rheumatologist-confirmed diagnosis is in stark contrast to the high rates of severe arthritis frequently reported by medicinal marijuana users, especially in Canada. Familiarity with marijuana as a recreational product may explain use for some as disease status was similar for both groups.
Background HIV self-testing (HIVST) is recommended by the WHO as an innovative strategy to reach UNAIDS targets to end HIV by 2030. HIVST with digital supports is defined as the use of digital interventions (e.g., website-based, social media, mobile HIVST applications (apps), text messaging (SMS), digital vending machines (digital VMs)) to improve the efficiency and impact of HIVST. HIVST deployment and integration in health services is an emerging priority. We conducted a systematic review aiming to close the gap in evidence that summarizes the impact of digitally supported HIVST and to inform policy recommendations. Methods We searched PubMed and Embase for articles and abstracts on HIVST with digital supports published during the period February 1st, 2010 to June 15th, 2021, following Cochrane guidelines and PRISMA methodology. We assessed feasibility, acceptability, preference, and impact outcomes across all populations and study designs. Metrics reported were willingness to use HIVST, preferences for HIVST delivery, proportion of first-time testers, HIVST uptake, HIVST kit return rate, and linkage to care. Heterogeneity of the interventions and reported metrics precluded us from conducting a meta-analysis. Findings 46 studies were narratively synthesized, of which 72% were observational and 28% were RCTs. Half of all studies (54%, 25/46) assessed web-based innovations (e.g., study websites, videos, chatbots), followed by social media (26%, 12/46), HIVST-specific apps (7%, 3/46), SMS (9%, 4/46), and digital VMs (4%, 2/46). Web-based innovations were found to be acceptable (77–97%), preferred over in-person and hybrid options by more first-time testers (47–48%), highly feasible (93–95%), and were overall effective in supporting linkage to care (53–100%). Social media and app-based innovations also had high acceptability (87–95%) and linkage to care proportions (80–100%). SMS innovations increased kit return rates (54–94%) and HIVST uptake among hard-to-reach groups. Finally, digital VMs were highly acceptable (54–93%), and HIVST uptake was six times greater when using digital VMs compared to distribution by community workers. Interpretation HIVST with digital supports was deemed feasible, acceptable, preferable, and was shown to increase uptake, engage first-time testers and hard-to-reach populations, and successfully link participants to treatment. Findings pave the way for greater use of HIVST interventions with digital supports globally.
Adherence to osteoporosis treatments is a critical parameter resulting in suboptimal effectiveness in real-life practice. The long-term effect of adherence on fracture risk has not been assessed. This was a retrospective study using provincial health insurance claims databases to assess the association between adherence to oral bisphosphonates (OBP) and incidence of osteoporotic fractures in all Ontario patients with osteoporosis between April 1996 and December 2009. Multivariate logistic regression models were used to assess the association between OBP adherence and fracture risk. Treatment duration was classified into 2-year intervals. Compliance was estimated with the medication possession ratio (MPR), and persistence was defined as the length of continuous therapy without a gap in refills >30 days. The study cohort was composed of 636,114 patients, among whom 36.1% were prescribed OBPs for 0 to 2 years, 19.7% for 2 to 4 years, 15.1% for 4 to 6 years, 12% for 6 to 8 years, 9.1% for 8 to 10 years, 6.1% for 10to 12 years, and 1.9% for 12 to 14 years. Overall, the mean (SD) compliance for the cohort was 0.72 (0.30) with 53.5% of the patients having compliance >80% and 24.6% being persistent with treatment during the 14-year follow-up period. Significant associations between high adherence and reduced fracture risk over the entire 14-year period were observed; the overall odds ratio for categorical compliance (MPR >80% or MPR 80%), continuous compliance, and persistence were 0.909 (95% confidence interval [CI] 0.893-0.925), 0.918 (95% CI 0.893-0.944), and 0.804 (95% CI 0.787-0.821), respectively. In conclusion, adherence to OBP in osteoporosis management is suboptimal in a real-life setting. A significant positive association exists between poor adherence and increased risk of osteoporotic fractures, which becomes augmented with longer treatment duration. ß
