RESUMEN

OBJECTIVE: Universally acknowledged standards for trustworthy guidelines include the necessity to ground recommendations in patient values and preferences. When information is limited-which is typically the case-guideline panels often find it difficult to explicitly integrate patient values and preferences into their recommendations. Our objective was to develop and evaluate a framework for systematically navigating guideline panels in incorporating patient values and preferences in making recommendations. STUDY DESIGN AND SETTING: In the context of developing a guideline for colorectal cancer screening, we generated an initial framework for creating panel surveys to elicit guideline panelists' views of patient values and preferences and to inform panel discussions on recommendations. With further applications in guidelines of diverse topic areas, we dynamically refined the framework through iterative discussions and consensus. RESULTS: The finial framework consists of five steps for creating and implementing panel surveys. The surveys can serve three objectives following from the quantitative information regarding patient values and preferences that guideline panels usually require. An accompanying video provides detailed instructions of the survey. CONCLUSION: The framework for creating and implementing panel surveys offers explicit guidance for guideline panels considering transparently and systematically incorporating patient values and preferences into guideline recommendations.

RESUMEN

BACKGROUND: Most systematic reviews of opioids for chronic pain have pooled treatment effects across individual opioids under the assumption they provide similar benefits and harms. We examined the comparative effects of individual opioids for chronic non-cancer pain through a network meta-analysis of randomised controlled trials. METHODS: We searched MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials to March 2021 for studies that enrolled patients with chronic non-cancer pain, randomised them to receive different opioids, or opioids vs placebo, and followed them for at least 4 weeks. Certainty of evidence was evaluated using the GRADE approach. RESULTS: We identified 82 eligible trials (22 619 participants) that evaluated 14 opioids. Compared with placebo, several opioids showed superiority to others for analgesia and improvement in physical function; however, when restricted to pooled-effect estimates supported by moderate certainty evidence, no differences between opioids were evident. Among opioids with moderate certainty evidence, all increased the risk of gastrointestinal adverse events compared with placebo, although no opioids were more harmful than others. Low to very low certainty evidence suggests that extended-release vs immediate-release opioids may provide similar benefits for pain relief and physical functioning, and gastrointestinal harms. CONCLUSIONS: Our findings support the pooling of effect estimates across different types and formulations of opioids to inform effectiveness for chronic non-cancer pain.

RESUMEN

CLINICAL QUESTION: What is the role of medical cannabis or cannabinoids for people living with chronic pain due to cancer or non-cancer causes? CURRENT PRACTICE: Chronic pain is common and distressing and associated with considerable socioeconomic burden globally. Medical cannabis is increasingly used to manage chronic pain, particularly in jurisdictions that have enacted policies to reduce use of opioids; however, existing guideline recommendations are inconsistent, and cannabis remains illegal for therapeutic use in many countries. RECOMMENDATION: The guideline expert panel issued a weak recommendation to offer a trial of non-inhaled medical cannabis or cannabinoids, in addition to standard care and management (if not sufficient), for people living with chronic cancer or non-cancer pain. HOW THIS GUIDELINE WAS CREATED: An international guideline development panel including patients, clinicians with content expertise, and methodologists produced this recommendation in adherence with standards for trustworthy guidelines using the GRADE approach. The MAGIC Evidence Ecosystem Foundation (MAGIC) provided methodological support. The panel applied an individual patient perspective. THE EVIDENCE: This recommendation is informed by a linked series of four systematic reviews summarising the current body of evidence for benefits and harms, as well as patient values and preferences, regarding medical cannabis or cannabinoids for chronic pain. UNDERSTANDING THE RECOMMENDATION: The recommendation is weak because of the close balance between benefits and harms of medical cannabis for chronic pain. It reflects a high value placed on small to very small improvements in self reported pain intensity, physical functioning, and sleep quality, and willingness to accept a small to modest risk of mostly self limited and transient harms. Shared decision making is required to ensure patients make choices that reflect their values and personal context. Further research is warranted and may alter this recommendation.

RESUMEN

UPDATES: This is the second version (first update) of the living systematic review, replacing the previous version (available as a data supplement). When citing this paper please consider adding the version number and date of access for clarity. OBJECTIVE: To determine and compare the effects of drug prophylaxis on severe acute respiratory syndrome coronavirus virus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (covid-19). DESIGN: Living systematic review and network meta-analysis (NMA). DATA SOURCES: World Health Organization covid-19 database, a comprehensive multilingual source of global covid-19 literature to 4 March 2022. STUDY SELECTION: Randomised trials in which people at risk of covid-19 were allocated to prophylaxis or no prophylaxis (standard care or placebo). Pairs of reviewers independently screened potentially eligible articles. METHODS: After duplicate data abstraction, we conducted random-effects bayesian network meta-analysis. We assessed risk of bias of the included studies using a modification of the Cochrane risk of bias 2.0 tool and assessed the certainty of the evidence using the grading of recommendations assessment, development and evaluation (GRADE) approach. RESULTS: The second iteration of this living NMA includes 32 randomised trials which enrolled 25 147 participants and addressed 21 different prophylactic drugs; adding 21 trials (66%), 18 162 participants (75%) and 16 (76%) prophylactic drugs. Of the 16 prophylactic drugs analysed, none provided convincing evidence of a reduction in the risk of laboratory confirmed SARS-CoV-2 infection. For admission to hospital and mortality outcomes, no prophylactic drug proved different than standard care or placebo. Hydroxychloroquine and vitamin C combined with zinc probably increase the risk of adverse effects leading to drug discontinuation­risk difference for hydroxychloroquine (RD) 6 more per 1000 (95% credible interval (CrI) 2 more to 10 more); for vitamin C combined with zinc, RD 69 more per 1000 (47 more to 90 more), moderate certainty evidence. CONCLUSIONS: Much of the evidence remains very low certainty and we therefore anticipate future studies evaluating drugs for prophylaxis may change the results for SARS-CoV-2 infection, admission to hospital and mortality outcomes. Both hydroxychloroquine and vitamin C combined with zinc probably increase adverse effects. SYSTEMATIC REVIEW REGISTRATION: This review was not registered. The protocol established a priori is included as a supplement. FUNDING: This study was supported by the Canadian Institutes of Health Research (grant CIHR-IRSC:0579001321).

RESUMEN

BACKGROUND: Opioids are frequently prescribed for the management of patients with chronic non-cancer pain (CNCP). Previous meta-analyses of efficacy and harms have combined treatment effects across all opioids; however, specific opioids, pharmacokinetic properties (ie, long acting vs short acting), or the type of formulation (ie, immediate vs extended release) may be a source of heterogeneity for pooled effects. METHODS: We will conduct a network meta-analysis (NMA) of randomized controlled trials evaluating opioids for CNCP. We will acquire eligible studies through systematic searches of EMBASE, MEDLINE, CINAHL, AMED, PsycINFO, and the Cochrane Central Registry of Controlled Trials (CENTRAL). Eligible studies will have randomly allocated adult CNCP patients to an oral or transdermal opioid versus another type of opioid (or formulation) or placebo, and follow patients for ≥ 4 weeks. We will collect outcome data for pain intensity, physical function, nausea, vomiting, and constipation. Pairs of reviewers will, independently and in duplicate, abstract data from eligible trials and assess risk of bias using a modified Cochrane tool. We will assess coherence of our networks through both a global test, and by comparing direct and indirect evidence for each comparison with node-splitting. RESULTS: Using a frequentist approach, we will conduct random effects multiple treatment meta-analysis to establish treatment effects of individual opioids for each outcome. The certainty of evidence for pooled treatment effects will be assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. We will categorize interventions from most to least effective based on the effect estimates obtained from NMAs and their associated certainty of evidence, as follows: superior to both placebo and alternatives; superior to placebo, but inferior to alternatives; and no better than placebo. CONCLUSION: This NMA will determine the relative effectiveness and adverse effects of individual opioids among patients with CNCP. Our results will help inform the appropriateness of assuming similar beneficial and adverse effects of varying opioid formulations. SYSTEMATIC REVIEW REGISTRATION: This systematic review is registered with Prospective Register of Systematic Reviews, an international prospective register of systematic reviews (registration no.: CRD42018110331), available at https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=110331.

RESUMEN

CLINICAL QUESTION: Recent 15-year updates of sigmoidoscopy screening trials provide new evidence on the effectiveness of colorectal cancer screening. Prompted by the new evidence, we asked: "Does colorectal cancer screening make an important difference to health outcomes in individuals initiating screening at age 50 to 79? And which screening option is best?" CURRENT PRACTICE: Numerous guidelines recommend screening, but vary on recommended test, age and screening frequency. This guideline looks at the evidence and makes recommendations on screening for four screening options: faecal immunochemical test (FIT) every year, FIT every two years, a single sigmoidoscopy, or a single colonoscopy. RECOMMENDATIONS: These recommendations apply to adults aged 50-79 years with no prior screening, no symptoms of colorectal cancer, and a life expectancy of at least 15 years. For individuals with an estimated 15-year colorectal cancer risk below 3%, we suggest no screening (weak recommendation). For individuals with an estimated 15-year risk above 3%, we suggest screening with one of the four screening options: FIT every year, FIT every two years, a single sigmoidoscopy, or a single colonoscopy (weak recommendation). With our guidance we publish the linked research, a graphic of the absolute harms and benefits, a clear description of how we reached our value judgments, and linked decision aids. HOW THIS GUIDELINE WAS CREATED: A guideline panel including patients, clinicians, content experts and methodologists produced these recommendations using GRADE and in adherence with standards for trustworthy guidelines. A linked systematic review of colorectal cancer screening trials and microsimulation modelling were performed to inform the panel of 15-year screening benefits and harms. The panel also reviewed each screening option's practical issues and burdens. Based on their own experience, the panel estimated the magnitude of benefit typical members of the population would value to opt for screening and used the benefit thresholds to inform their recommendations. THE EVIDENCE: Overall there was substantial uncertainty (low certainty evidence) regarding the 15-year benefits, burdens and harms of screening. Best estimates suggested that all four screening options resulted in similar colorectal cancer mortality reductions. FIT every two years may have little or no effect on cancer incidence over 15 years, while FIT every year, sigmoidoscopy, and colonoscopy may reduce cancer incidence, although for FIT the incidence reduction is small compared with sigmoidoscopy and colonoscopy. Screening related serious gastrointestinal and cardiovascular adverse events are rare. The magnitude of the benefits is dependent on the individual risk, while harms and burdens are less strongly associated with cancer risk. UNDERSTANDING THE RECOMMENDATION: Based on benefits, harms, and burdens of screening, the panel inferred that most informed individuals with a 15-year risk of colorectal cancer of 3% or higher are likely to choose screening, and most individuals with a risk of below 3% are likely to decline screening. Given varying values and preferences, optimal care will require shared decision making.

RESUMEN

OBJECTIVES: To identify credible anchor-based minimal important differences (MIDs) for patient-reported outcome measures (PROMs) relevant to a BMJ Rapid Recommendations addressing subacromial decompression surgery for shoulder pain. DESIGN: Systematic review. OUTCOME MEASURES: Estimates of anchor-based MIDs, and their credibility, for PROMs judged by the parallel BMJ Rapid Recommendations panel as important for informing their recommendation (pain, function and health-related quality of life (HRQoL)). DATA SOURCES: MEDLINE, EMBASE and PsycINFO up to August 2018. STUDY SELECTION AND REVIEW METHODS: We included original studies of any intervention for shoulder conditions reporting estimates of anchor-based MIDs for relevant PROMs. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria. Six reviewers, working in pairs, independently extracted data from eligible studies using a predesigned, standardised, pilot-tested extraction form and independently assessed the credibility of included studies using an MID credibility tool. RESULTS: We identified 22 studies involving 5562 patients that reported 74 empirically estimated anchor-based MIDs for 10 candidate instruments to assess shoulder pain, function and HRQoL. We identified MIDs of high credibility for pain and function outcomes and of low credibility for HRQoL. We offered median estimates for the systematic review team who applied these MIDs in Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence summaries and in their interpretations of results in the linked systematic review addressing the effectiveness of surgery for shoulder pain. CONCLUSIONS: Our review provides anchor-based MID estimates, as well as a rating of their credibility, for PROMs for patients with shoulder conditions. The MID estimates inform the interpretation for a linked systematic review and guideline addressing subacromial decompression surgery for shoulder pain, and could also prove useful for authors addressing other interventions for shoulder problems.

RESUMEN

CLINICAL QUESTION: Do adults with atraumatic shoulder pain for more than 3 months diagnosed as subacromial pain syndrome (SAPS), also labelled as rotator cuff disease, benefit from subacromial decompression surgery? This guideline builds on to two recent high quality trials of shoulder surgery. CURRENT PRACTICE: SAPS is the common diagnosis for shoulder pain with several first line treatment options, including analgesia, exercises, and injections. Surgeons frequently perform arthroscopic subacromial decompression for prolonged symptoms, with guidelines providing conflicting recommendations. RECOMMENDATION: The guideline panel makes a strong recommendation against surgery. HOW THIS GUIDELINE WAS CREATED: A guideline panel including patients, clinicians, and methodologists produced this recommendation in adherence with standards for trustworthy guidelines and the GRADE system. The recommendation is based on two linked systematic reviews on (a) the benefits and harms of subacromial decompression surgery and (b) the minimally important differences for patient reported outcome measures. Recommendations are made actionable for clinicians and their patients through visual overviews. These provide the relative and absolute benefits and harms of surgery in multilayered evidence summaries and decision aids available in MAGIC (www.magicapp.org) to support shared decisions and adaptation. THE EVIDENCE: Surgery did not provide important improvements in pain, function, or quality of life compared with placebo surgery or other options. Frozen shoulder may be more common with surgery. UNDERSTANDING THE RECOMMENDATION: The panel concluded that almost all informed patients would choose to avoid surgery because there is no benefit but there are harms and it is burdensome. Subacromial decompression surgery should not be offered to patients with SAPS. However, there is substantial uncertainty in what alternative treatment is best.

RESUMEN

CONTEXT: Pharmacological thromboprophylaxis involves balancing a lower risk of venous thromboembolism (VTE) against a higher risk of bleeding, a trade-off that critically depends on the risks of VTE and bleeding in the absence of prophylaxis (baseline risk). OBJECTIVE: To provide estimates of the baseline risk of symptomatic VTE and bleeding requiring reoperation in urological cancer surgery. EVIDENCE ACQUISITION: We identified contemporary observational studies reporting symptomatic VTE or bleeding after urological procedures. We used studies with the lowest risk of bias and accounted for use of thromboprophylaxis and length of follow-up to derive best estimates of the baseline risks within 4 wk of surgery. We used the GRADE approach to assess the quality of the evidence. EVIDENCE SYNTHESIS: We included 71 studies reporting on 14 urological cancer procedures. The quality of the evidence was generally moderate for prostatectomy and cystectomy, and low or very low for other procedures. The duration of thromboprophylaxis was highly variable. The risk of VTE in cystectomies was high (2.6-11.6% across risk groups) whereas the risk of bleeding was low (0.3%). The risk of VTE in prostatectomies varied by procedure, from 0.2-0.9% in robotic prostatectomy without pelvic lymph node dissection (PLND) to 3.9-15.7% in open prostatectomy with extended PLND. The risk of bleeding was 0.1-1.0%. The risk of VTE following renal procedures was 0.7-2.9% for low-risk patients and 2.6-11.6% for high-risk patients; the risk of bleeding was 0.1-2.0%. CONCLUSIONS: Extended thromboprophylaxis is warranted in some procedures (eg, open and robotic cystectomy) but not others (eg, robotic prostatectomy without PLND in low-risk patients). For "close call" procedures, decisions will depend on values and preferences with regard to VTE and bleeding. PATIENT SUMMARY: Clinicians often give blood thinners to patients to prevent blood clots after surgery for urological cancer. Unfortunately, blood thinners also increase bleeding. This study provides information on the risk of clots and bleeding that is crucial in deciding for or against giving blood thinners.

RESUMEN

Ezetimibe is widely used in combination with statins to reduce low-density lipoprotein. We sought to examine the impact of ezetimibe when added to statins on patient-important outcomes. Medline, EMBASE, CINAHL, and CENTRAL were searched through July, 2016. Randomized controlled trials (RCTs) of ezetimibe combined with statins versus statins alone that followed patients for at least 6 months and reported on at least one of all-cause mortality, cardiovascular deaths, non-fatal myocardial infarctions (MI), and non-fatal strokes were included. Pairs of reviewers extracted study data and assessed risk of bias independently and in duplicate. Quality of evidence was assessed using the GRADE approach. We conducted a narrative review with complementary subgroup and sensitivity analyses. IMPROVE-IT study enrolled 93% of all patients enrolled in the 8 included trials. Our analysis of the IMPROVE-IT study results showed that in patients at high risk of cardiovascular events, ezetimibe added to statins was associated with i) a likely reduction in non-fatal MI (17 fewer/1000 treated over 6 years, moderate certainty in evidence); ii) a possible reduction in non-fatal stroke (6 fewer/1000 treated over 6 years, low certainty); iii) no impact on myopathy (moderate certainty); iv) potentially no impact on all-cause mortality and cardiovascular death (both moderate certainty); and v) possibly no impact on cancer (low certainty). Addition of ezetimibe to moderate-dose statins is likely to result in 17 fewer MIs and possibly 6 fewer strokes/1000 treated over 6 years but is unlikely to reduce all-cause mortality or cardiovascular death. Patients who place a high value on a small absolute reduction in MI and are not adverse to use of an additional medication over a long duration may opt for ezetimibe in addition to statin therapy. Our analysis revealed no increased specific harms associated with addition of ezetimibe to statins.

RESUMEN

CONTEXT: Pharmacological thromboprophylaxis involves a trade-off between a reduction in venous thromboembolism (VTE) and increased bleeding. No guidance specific for procedure and patient factors exists in urology. OBJECTIVE: To inform estimates of absolute risk of symptomatic VTE and bleeding requiring reoperation in urological non-cancer surgery. EVIDENCE ACQUISITION: We searched for contemporary observational studies and estimated the risk of symptomatic VTE or bleeding requiring reoperation in the 4 wk after urological surgery. We used the GRADE approach to assess the quality of the evidence. EVIDENCE SYNTHESIS: The 37 eligible studies reported on 11 urological non-cancer procedures. The duration of prophylaxis varied widely both within and between procedures; for example, the median was 12.3 d (interquartile range [IQR] 3.1-55) for open recipient nephrectomy (kidney transplantation) studies and 1 d (IQR 0-1.3) for percutaneous nephrolithotomy, open prolapse surgery, and reconstructive pelvic surgery studies. Studies of open recipient nephrectomy reported the highest risks of VTE and bleeding (1.8-7.4% depending on patient characteristics and 2.4% for bleeding). The risk of VTE was low for 8/11 procedures (0.2-0.7% for patients with low/medium risk; 0.8-1.4% for high risk) and the risk of bleeding was low for 6/7 procedures (≤0.5%; no bleeding estimates for 4 procedures). The quality of the evidence supporting these estimates was low or very low. CONCLUSIONS: Although inferences are limited owing to low-quality evidence, our results suggest that extended prophylaxis is warranted for some procedures (eg, kidney transplantation procedures in high-risk patients) but not others (transurethral resection of the prostate and reconstructive female pelvic surgery in low-risk patients). PATIENT SUMMARY: The best evidence suggests that the benefits of blood-thinning drugs to prevent clots after surgery outweigh the risks of bleeding in some procedures (such as kidney transplantation procedures in patients at high risk of clots) but not others (such as prostate surgery in patients at low risk of clots).

RESUMEN

OBJECTIVES: To identify the most credible anchor-based minimal important differences (MIDs) for patient important outcomes in patients with degenerative knee disease, and to inform BMJ Rapid Recommendations for arthroscopic surgery versus conservative management DESIGN: Systematic review. OUTCOME MEASURES: Estimates of anchor-based MIDs, and their credibility, for knee symptoms and health-related quality of life (HRQoL). DATA SOURCES: MEDLINE, EMBASE and PsycINFO. ELIGIBILITY CRITERIA: We included original studies documenting the development of anchor-based MIDs for patient-reported outcomes (PROs) reported in randomised controlled trials included in the linked systematic review and meta-analysis and judged by the parallel BMJ Rapid Recommendations panel as critically important for informing their recommendation: measures of pain, function and HRQoL. RESULTS: 13 studies reported 95 empirically estimated anchor-based MIDs for 8 PRO instruments and/or their subdomains that measure knee pain, function or HRQoL. All studies used a transition rating (global rating of change) as the anchor to ascertain the MID. Among PROs with more than 1 estimated MID, we found wide variation in MID values. Many studies suffered from serious methodological limitations. We identified the following most credible MIDs: Western Ontario and McMaster University Osteoarthritis Index (WOMAC; pain: 12, function: 13), Knee injury and Osteoarthritis Outcome Score (KOOS; pain: 12, activities of daily living: 8) and EuroQol five dimensions Questionnaire (EQ-5D; 0.15). CONCLUSIONS: We were able to distinguish between more and less credible MID estimates and provide best estimates for key instruments that informed evidence presentation in the associated systematic review and judgements made by the Rapid Recommendation panel. TRIAL REGISTRATION NUMBER: CRD42016047912.

RESUMEN

OBJECTIVE: To investigate patients' values and preferences regarding aortic valve replacement therapy for aortic stenosis. SETTING: Studies published after transcatheter aortic valve insertion (TAVI) became available (2002). PARTICIPANTS: Adults with aortic stenosis who are considering or have had valve replacement, either TAVI or via surgery (surgical aortic valve replacement, SAVR). OUTCOME MEASURES: We sought quantitative measurements, or qualitative descriptions, of values and preferences. When reported, we examined correlations between preferences and objective (eg, ejection fraction) or subjective (eg, health-related quality of life) measures of health. RESULTS: We reviewed 1348 unique citations, of which 2 studies proved eligible. One study of patients with severe aortic stenosis used a standard gamble study to ascertain that the median hypothetical mortality risk patients were willing to tolerate to achieve full health was 25% (IQR 25-50%). However, there was considerable variability; for mortality risk levels defined by current guidelines, 130 participants (30%) were willing to accept low-to-intermediate risk (≤8%), 224 (51%) high risk (>8-50%) and 85 (19%) a risk that guidelines would consider prohibitive (>50%). Study authors did not, however, assess participants' understanding of the exercise, resulting in a potential risk of bias. A second qualitative study of 15 patients identified the following factors that influence patients to undergo assessment for TAVI: symptom burden; expectations; information support; logistical barriers; facilitators; obligations and responsibilities. The study was limited by serious risk of bias due to authors' conflict of interest (5/9 authors industry-funded). CONCLUSIONS: Current evidence on patient values and preferences of adults with aortic stenosis is very limited, and no studies have enrolled patients deciding between TAVI and SAVR. On the basis of the data available, there is evidence of variability in individual values and preferences, highlighting the importance of well-informed and shared decision-making with patients facing this decision. TRIAL REGISTRATION NUMBER: PROSPERO CRD42016041907.

RESUMEN

Data evaluating the screening practices for viral hepatitides and sexually transmitted infections (STIs) in patients presenting for non-occupational HIV post-exposure prophylaxis (nPEP) care are limited. Screening practices and prevalences of viral hepatitides and STIs were evaluated in 126 patients presenting to a dedicated HIV prevention clinic for HIV nPEP. Three patients (2.4%) were diagnosed with chronic hepatitis C infection, 28 (22.2%) did not have surface antibodies in sufficient quantity to confer immunity to hepatitis B, and six (4.8%) were diagnosed with an STI. A multivariate regression model did not predict any demographic or clinical features predictive of HBV non-immunity. Beyond screening for HIV infection, evaluation for viral hepatitides and STIs is an important feature in the care of patients presenting for HIV nPEP.

RESUMEN

The uptake of pre-exposure prophylaxis (PrEP) for HIV prevention remains low. We hypothesized that a high proportion of patients presenting for HIV non-occupational post-exposure prophylaxis (nPEP) would be candidates for PrEP based on current CDC guidelines. Outcomes from a comprehensive HIV Prevention Clinic are described. We evaluated all patients who attended the HIV Prevention Clinic for nPEP between January 1, 2013 and September 30, 2014. Each patient was evaluated for PrEP candidacy based on current CDC-guidelines and subjectively based on physician opinion. Patients were then evaluated for initiation of PrEP if they met guideline suggestions. Demographic, social, and behavioral factors were then analyzed with logistic regression for associations with PrEP candidacy and initiation. 99 individuals who attended the nPEP clinic were evaluated for PrEP. The average age was 32 years (range, 18-62), 83 (84%) were male, of whom 46 (55%) men who had have sex with men (MSM). 31 (31%) met CDC guidelines for PrEP initiation, which had very good agreement with physician recommendation (kappa=0.88, 0.78-0.98). Factors associated with PrEP candidacy included sexual exposure to HIV, prior nPEP use, and lack of drug insurance (p<0.05 for all comparisons). Combining nPEP and PrEP services in a dedicated clinic can lead to identification of PrEP candidates and may facilitate PrEP uptake. Strategies to ensure equitable access of PrEP should be explored such that those without drug coverage may also benefit from this effective HIV prevention modality.

RESUMEN

HIV and intimate partner violence (IPV) epidemics propagate and interact in a syndemic fashion contributing to excess burden of disease and poorer health outcomes. In order to understand the impact of IPV on HIV disease management, a universal screening program was implemented in the Southern Alberta Clinic in May 2009. We evaluated our IPV screening protocol and made recommendations for its usage in HIV care. IPV data obtained from patients were evaluated, supplemented with responses from a subset of in-depth interviews. 35% of 1721 patients reported experiencing IPV. Prevalence was higher among females (46%), Aboriginal Canadians (67%), bisexual male/females (48%), and gay males (35%). Of 158 patients interviewed, only 22% had previously been asked about IPV in any health care setting. Patients were responsive to routine IPV screening emphasizing that referral services need to be easily accessible. 23% of patients disclosing IPV subsequently connected to additional IPV resources after screening. We recommend that universal IPV screening be incorporated within regular HIV clinic care. The IPV survey should be given after trust has been established with regular follow-up every 6-12 months. A referral process to local agencies dealing with IPV must be in place for patients disclosing abuses.
