Pick up a small amount of fresh growth from the MacConkey agar with a platinum (not Nichrome) loop or a clean wooden stick or toothpick. A positive reaction is indicated by the appearance of a dark purple colour on the paper within 10 seconds. Among the Gram-negative rods Vibrio, Aeromonas, Plesiomonas, Pseudomonas, and Alcaligenes are oxidase-positive; all Enterobacteriaceae are oxidase-negative. The oxidase reagent should be tested regularly with positive and negative control strains. A positive reaction is indicated by the suspension within 60 seconds: it looses its turbidity and becomes mucoid; a “mucoid string” can be drawn when the loop is slowly lifted away from the drop. A few strains of Aeromonas may show a weak and delayed string at about 60 seconds. If this is conﬁrmed, report: “Vibrio cholerae isolated (provisional identiﬁcation)”. Campylobacter jejuni and Campylobacter coli Examine the Campylobacter plates after 48–72 hours of incubation. Suspect colonies should be screened with three presumptive tests: oxidase test, wet mount preparation under dark-ﬁeld or phase-contrast microscope, and Gram-stain. If a dark-ﬁeld or phase-contrast microscope is not available, colonies may be rapidly screened for typical cell morphology by staining with Gram’s crystal-violet solution. Campylobacter species are oxidase-positive, they are motile with a darting, tumbling motility, and they appear as simple curved or spiral-shaped rods (seagull wings or “S”-shape). If this is conﬁrmed, report: “Campylobacter isolated (provisional identiﬁcation)”. On anaerobic blood agar the colony morphology varies and other fea-tures should be looked for to detect the organism. Typically, colonies are grey, opaque and non-haemolytic at 24–48 hours, but a few strains may be green-ish blue due to a-type haemolysis. After 48–72 hours of incubation, colonies may develop a distinctly light grey to white centre. If the colonies are lecithinase-and lipase-negative and show yellow-green ﬂuores-cence when illuminated with Wood’s lamp, report: “Clostridium difﬁcile iso-lated (provisional identiﬁcation)”. Final microbiological identiﬁcation Before the ﬁnal report is made, the cultures should always be checked for pure growth, and the identiﬁcation should be conﬁrmed with additional biochemi-cal tests. Pick a suspect colony well-separated from other colonies on the plate and subculture it in nutrient broth for biochemical tests, to an agar slope for serological tests, and plate it on MacConkey agar to conﬁrm the purity of the culture. Identiﬁcation of Shigella and Salmonella may sometimes pose a problem, because some strains vary in their biochemical reactions and may even share antigens with other Gram-negative organisms. Examine the reactions after overnight incubation and identify the isolate according to Table 12. If the results agree with the culture of Salmonella, proceed with the serological identiﬁcation. Examine the reactions after overnight incubation and identify the isolate according to Table 13. If the results agree with the culture of Shigella, proceed with the serological identiﬁcation. Some serotypes may provisionally be identiﬁed by biochemical reactions and divided into biotypes. Biochemical reactions of Shigella species and serotypes Ornithine Fermentation: Fermentation: Catalase Glucose decarboxylase lactose/sucrose mannitol gas Shigella dysenteriae Serotype 1 (shigae) Serotype 2 (schmitzii) Serotypes 3–10 Shigella ﬂexneri Serotype 1–5, X and Y Serotype 6 Newcastle Serotype 6 Manchester Serotype 6 Boyd 88 Shigella boydii Serotype 1–13, 15 Serotype 14 Shigella sonnei (delayed) S. The Newcastle strain of serotype 6 does not ferment mannitol, but produces gas from glucose; the Manchester strain produces acid and gas from glucose and mannitol; the Boyd 88 strain produces acid but no gas from glucose and mannitol. Examine the reactions after overnight incubation and identify the isolate according to Table 15. Vibrio cholerae If the results of the preliminary tests are consistent with a Vibrio strain, inocu-late ornithine decarboxylase, Simmons citrate agar, and sucrose peptone water, and incubate overnight. If one of these reactions is negative, test for aesculin hydrolysis, Voges–Proskauer, and fermentation of mannitol, arabi-nose and arbutin. Examine the reactions after overnight incubation and iden-tify the isolate according to Table 16. Differentiation of biotypes of Vibrio cholerae Biotype Classical El Tor Haemagglutination Negative reaction, no growth* Positive reaction, growth* Polymyxin B (50 units) Sensitive Resistant Voges–Proskauer Negative reaction, no growth* Positive reaction, growth* Haemolysis Negative reaction, no growth Variable *Aberrant reactions may occur. If a speciﬁc anti-Vibrio cholerae serogroup O1 serum is available, make a rapid slide agglutination test. If the antiserum is not available or if the identiﬁcation is uncer-tain, send the isolate to a reference laboratory. Divide a clean glass slide into several squares with a pencil and place a loopful (3mm) of the red cell suspension in each square. Clumping of the red cells occurs within 30–60 seconds with strains of the El Tor biotype. Known haemagglutinating (El Tor) and non-haemagglutinating strains should be used as controls for each new suspension of red cells. Newly isolated strains of classical biotypes are usually negative in the test, but old laboratory strains of the classical biotype may not always be negative in this reaction. Spread a loopful of overnight peptone water culture of the isolate on a Mueller–Hinton or meat-extract agar. Place a susceptibility disk containing 50 units of polymyxin B in the middle of the culture.

This system collects, • Referral to primary health care services analyses and interprets injury information of ten the federal government will provide $1. While we need to maintain our efforts in continuing to improve these trends, we can conclude that short-term targets are met. The problems of illicit drug use, suicide, child and spousal abuse are harder to tackle. Similarly, rates of child and spousal abuse may be viewed as barometers of violence experienced by a society. A few regions performing poorly on these indicators have likely influenced the overall provincial rates. We need to focus efforts on these regions when determining causes and finding long-term solutions. Use seat belts, infant car seats, bicycle helmets and other safety equipment properly. Recognize that violence and abuse are not private family matters and that they are against the law. Governments: • Work on strategies identified in the provincial injury prevention plan for children and youth. Although many of the data about seniors has been presented already in the text, below is a summary of some findings for younger and older seniors towards the reduction of preventable illness, disabilities, and premature death. Injury • Each year, an estimated one in three seniors, or about 147,000 British Columbians, will have a fall, almost half of whom will sustain a minor injury and 5 to 25 per cent of whom will sustain a major injury. A single hip fracture adds $24,400 to $28,000 in direct health costs to the system. Almost half of people who sustain a hip fracture never recover full functioning and 20 per cent die within a year of a hip fracture. Results from the same survey indicate that emotional and financial abuse against older adults cuts across all socio-demographic lines. Suicide rates are dramatically different between males and females, even for seniors. Among males, older seniors are more likely than younger seniors to commit suicide. Twenty-seven per cent also reported that that they have at least four or more chronic conditions. These efforts will not only increase life expectancy, they will also increase disability-free life expectancy, resulting in an improved quality of life for senior citizens.

Please see the appendix for a summary of the goals, objectives, key strategies and core indicators. Viral Load and Heterosexual Transmission of Human of Human Immunodeﬁciency Virus Type 1. Purpose and Scope the purpose of the Progress Report is to document the progress made on an annual basis in implementing the key strategies in the Priorities for Action. Work is currently underway to develop better indicators and identify improved data sources in order to monitor progress on the achievement of the four provincial goals. This work is being done in partnership with health authorities and provincial health agencies. Annual data related to revised indicators will provide the basis for future progress reports. It also provides an update on the key strategies for achieving each goal and gives some select examples of how the strategies are being implemented across the province. If an individual chooses to disclose why they have sought a test, the manner in which their response is currently recorded and reported prevents a scientiﬁc analysis of the data that deﬁnitively establishes a relationship to public health partner notiﬁcation efforts. Furthermore, no data is collected as part of this process that could link a date when partner notiﬁcation occurred with the date of the test. Community agencies in each health region are also responding to the challenge of engaging at-risk populations. These interventions include social marketing, peer outreach, and communication skills development. This messaging builds on the “Do the Math” themes developed by the Sex Now Survey Team. One of the key tenets of this messaging plan is to avoid a negative, fear-based campaign and to frame the message as positive and empowering, using an asset-based approach. There were three presentations developed for the campaign, one for physicians oﬃces and health units and the other two geared towards gay community newspapers and advertising space. The approach was adapted to reﬂect the Canadian demographic of gay men, including Aboriginal men, and speciﬁc ethno-cultural populations. The How Do You Know What You Know campaign consists of print advertising, transit and billboard advertising, posters, washroom advertising, postcards and a website: www. The campaign materials depict various inner voice assumptions men might make in a casual sexual encounter. This work took the form of educational initiatives and workshops facilitated by trained peer educators known as the Speakers Bureau, an effective approach for reaching vulnerable youth. This workshop may also include condom demonstrations and the distribution of printed materials and condoms when appropriate. Accessing the women-speciﬁc information needed can prove to be even more challenging. Another key component of the site is information designed speciﬁcally for newly diagnosed women who may be overwhelmed by feelings of fear, anger, confusion or despair. Chee Mamuk engages in community, policy and professional development to beneﬁt Aboriginal people on and off reserve. It also helps build organizational and community capacity through research, data collection and analysis, and materials production. As a result, more Aboriginal people are coming forward for testing and referral to appropriate care, treatment and support. Requests for Chee Mamuks expertise and resources come from across Canada, United States, Jamaica and Argentina. With this in mind, Chee Mamuk has produced “ Empowerment, Support and Healing”, a comprehensive set of culturally appropriate pamphlets for Aboriginal women. The material was produced in consultation with physicians, nurses, and community workers to ensure scientiﬁc accuracy, cultural relevancy and clarity. Outreach initiatives included using social networking to track the ongoing syphilis outbreak among vulnerable populations in Vancouver, and hiring peer outreach workers to engage hard to reach, at risk population groups. Research activities included participation in the Vancouver sites of the Health Canada Street Youth Study and North American Opiate Medication Initiative. Street nurses and Latin American and Vietnamese outreach workers trained peers to disseminate knowledge to their communities. Status: In May 2004, the Ministry of Health Services released a provincial report entitled Every Door is the Right Door: A British Columbia Framework to Address Problematic Substance Use and Addictions. This planning framework is intended to guide and support health authorities and community partners in providing effective responses to addictions and problematic substance use. The framework proposes a comprehensive continuum of services built on four fundamental concepts: population health, health promotion, harm reduction and community capacity-building. Every Door is the Right Door provides examples of best practices in addressing problematic substance use, many of which signiﬁcantly overlap with best practices in preventing transmission of communicable diseases.

While guidelines are useful aids to assist providers in determining appropriate practices for many patients with specific clinical problems or prevention issues, guidelines are not meant to replace the clinical judgment of the individual provider or establish a standard of care. The recommendations contained in the guidelines may not be appropriate for use in all circumstances. A decision to adopt any particular recommendation must be made by the provider in light of the circumstances presented by the individual patient. The purpose of this guideline is five-fold: • Provide an evidence-based approach to the diagnosis and management of acute pulmonary embolism in clinically stable patients. We reviewed the risks and benefits of the medications, and talked about the advantages and disadvantages of outpatient treatment. Heres a summary of what we talked about for treatment during your visit: Advantages and disadvantages of outpatient treatment Advantages: Disadvantages: • No or less time in the hospital • Concern if something happens that • More mobility requires immediate medical care • Lower cost (avoiding co-pays • Possible need for routine lab and and out-of-pocket expenses blood tests associated with inpatient care) • Possible health problems if • More comfortable in own home medication is not taken as prescribed Additional points to consider when discussing treatment setting with the patient: • Advantage: Avoiding a hospital stay lowers the risk of hospital-acquired infections or injuries.

The patients most likely to benefit from indefinite treatment are those with a high risk of recurrence and a low risk of bleeding. Bleeding risk factors include • Active bleeding • Acquired bleeding disorder • Thrombocytopenia • Lumbar puncture/epidural/spinal anesthesia within the previous 4 hours or expected within the next 12 hours • Active stroke • Current use of anticoagulants • Uncontrolled systolic hypertension (> 230/120 mm Hg) • Untreated inherited bleeding disorders such as hemophilia or von Willebrand disease • High fall risk Anticoagulation treatment duration by population Note: Repeat imaging is not required before stopping anticoagulation unless the patient is symptomatic.

As part of our improvement process, the Kaiser Permanente Washington guideline team is working towards developing new clinical guidelines and updating the current guidelines every 2–3 years. To achieve this goal, we are adapting evidence-based recommendations from high-quality national and international external guidelines, if available and appropriate. The external guidelines should meet several quality standards to be considered for adaptation. They must: be developed by a multidisciplinary team with no or minimal conflicts of interest; be evidence-based; address a population that is reasonably similar to our population; and be transparent about the frequency of updates and the date the current version was completed. In addition to identifying the recently published guidelines that meet the above standards, a literature search was conducted to identify studies relevant to the key questions that are not addressed by the external guidelines.

Venous thromboembolism prophylaxis and treatment in patients with cancer: American Society of Clinical Oncology clinical practice guideline update 2014. In terms of clinically relevant bleeding, edoxaban and dabigatran were safer than conventional treatment. Apixaban appears to be associated with less major bleeding compared to dabigatran and edoxaban, as well as lower risk of composite endpoint of major or clinically relevant nonmajor bleeding when compared to any of the three other agents. It is to be noted, however, that patients randomized to dabigatran or edoxaban receive an initial heparin treatment, while those receiving rivaroxaban or apixaban do not receive heparin, which would bias the results. In a 2015 meta-analysis, Marik and colleagues calculated that the annualized rate of events after discontinuation of treatment was 6.
