Evaluation of a multisectoral intervention to mitigate the risk of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmission in long-term care facilities.

OBJECTIVE: A Canadian health authority implemented a multisectoral intervention designed to control severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmission during long-term care facility (LTCF) outbreaks. The primary objective was to evaluate the effectiveness of the intervention 14 days after implementation. DESIGN: Quasi-experimental, segmented regression analysis. INTERVENTION: A series of outbreak measures classified into 4 categories: case and contact management, proactive case detection, rigorous infection control practices and resource prioritization and stewardship. METHODS: A mixed-effects segmented Poisson regression model was fitted to the incidence rate of coronavirus disease 2019 (COVID-19), calculated every 2 days, within each facility and case type (staff vs residents). For each facility, the outbreak time period was segmented into an early outbreak period (within 14 days of the intervention) and postintervention period (beyond 14 days following the intervention). Model outputs quantified COVID-19 incidence trend and rate changes between these 2 periods. A secondary model was constructed to identify effect modification by case type. RESULTS: The significant upward trend in COVID-19 incidence rate during the early outbreak period (rate ratio [RR], 1.07; 95% confidence interval [CI], 1.03-1.11; P < .001) reversed during the postintervention period (RR, 0.73; 95% CI, 0.67-0.80; P < .001). The average trend did not differ by case type during the early outbreak period (P > .05) or the postintervention period (P > .05). However, staff had a 70% larger decrease in the average rate of COVID-19 during the postintervention period than residents (RR, 0.30; 95% CI, 0.10-0.88; P < .05). CONCLUSIONS: Our study provides evidence for the effectiveness of this intervention to reduce the transmission of COVID-19 in LTCFs. This intervention can be adapted and utilized by other jurisdictions to protect the vulnerable individuals in LTCFs.

Environmental detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from medical equipment in long-term care facilities undergoing COVID-19 outbreaks.

Environmental sampling was conducted at long-term care facilities to determine the extent of surface contamination with severe acute respiratory syndrome coronavirus 2 virus. Medical equipment used throughout the facility was determined to be contaminated.

Abortion health services in Canada: Results of a 2012 national survey.

OBJECTIVE: To determine the location of Canadian abortion services relative to where reproductive-age women reside, and the characteristics of abortion facilities and providers. DESIGN: An international survey was adapted for Canadian relevance. Public sources and professional networks were used to identify facilities. The bilingual survey was distributed by mail and e-mail from July to November 2013. SETTING: Canada. PARTICIPANTS: A total of 94 abortion facilities were identified. MAIN OUTCOME MEASURES: The number and location of services were compared with the distribution of reproductive-age women by location of residence. RESULTS: We identified 94 Canadian facilities providing abortion in 2012, with 48.9% in Quebec. The response rate was 83.0% (78 of 94). Facilities in every jurisdiction with services responded. In Quebec and British Columbia abortion services are nearly equally present in large urban centres and rural locations throughout the provinces; in other Canadian provinces services are chiefly located in large urban areas. No abortion services were identified in Prince Edward Island. Respondents reported provision of 75 650 abortions in 2012 (including 4.0% by medical abortion). Canadian facilities reported minimal or no harassment, in stark contrast to American facilities that responded to the same survey. CONCLUSION: Access to abortion services varies by region across Canada. Services are not equitably distributed in relation to the regions where reproductive-age women reside. British Columbia and Quebec have demonstrated effective strategies to address disparities. Health policy and service improvements have the potential to address current abortion access inequity in Canada. These measures include improved access to mifepristone for medical abortion; provincial policies to support abortion services; routine abortion training within family medicine residency programs; and increasing the scope of practice for nurses and midwives to include abortion provision.

First-trimester medical abortion practices in Canada: National survey.

OBJECTIVE: To understand the current availability and practice of first-trimester medical abortion (MA) in Canada. DESIGN: Using public sources and professional networks, abortion facilities across Canada were identified for a cross-sectional survey on medical and surgical abortion. English and French surveys were distributed by surface or electronic mail between July and November 2013. SETTING: Canada. PARTICIPANTS: A total of 94 abortion facilities were identified. MAIN OUTCOME MEASURES: Descriptive statistics on MA practice and facility and provider characteristics, as well as comparisons of MA practice by facility and provider characteristics using χ2 and t tests. RESULTS: A total of 78 of 94 (83.0%) facilities responded. Medical abortion represented 3.8% of first-trimester abortions reported (2706 of 70 860) in 2012. Among the facilities offering MA, 45.0% performed fewer than 500 first-trimester abortions a year, while 35.0% performed more than 1000. More MAs were performed in private offices or ambulatory health centres than in hospitals. Sixty-two physicians from 28 of 78 facilities reported providing first-trimester MA; 87.1% also provided surgical abortion. More than three-quarters of MA physicians were female and 56.5% were family physicians. A preponderance (85.2%) of providers offered methotrexate with misoprostol. Nearly all physicians (90.3%) required patients to have an ultrasound before MA, and 72.6% assessed the completion of the abortion with ultrasonography. Most physicians (74.2%) offered MA through 49 days after the onset of the last menstrual period, and 21.0% offered MA through 50 to 56 days; 37.1% reported providing MA to patients who lived more than 2 hours away. Four physicians from 1 site provided MA via telemedicine. CONCLUSION: In Canada, MA provision using methotrexate and misoprostol is consistent with best-practice guidelines, but MA is rare and its availability is unevenly distributed.

Whole-Genome Sequencing of Measles Virus Genotypes H1 and D8 During Outbreaks of Infection Following the 2010 Olympic Winter Games Reveals Viral Transmission Routes.

We used whole-genome sequencing to investigate a dual-genotype outbreak of measles occurring after the XXI Olympic Winter Games in Vancouver, Canada. By sequencing 27 complete genomes from H1 and D8 genotype measles viruses isolated from outbreak cases, we estimated the virus mutation rate, determined that person-to-person transmission is typically associated with 0 mutations between isolates, and established that a single introduction of H1 virus led to the expansion of the outbreak beyond Vancouver. This is the largest measles genomics project to date, revealing novel aspects of measles virus genetics and providing new insights into transmission of this reemerging viral pathogen.
