Experiences of Using Cochrane Systematic Reviews by Local HTA Units.

This study evaluated the use of Cochrane systematic reviews (CSRs) by Quebec's local health technology assessment (HTA) units to promote efficiency in hospital decision-making. An online survey was conducted to examine: Characteristics of the HTA units; Knowledge about works and services from the Cochrane Collaboration; Level of satisfaction about the use of CSRs; Facilitating factors and barriers to the implementation of CSRs evidence in a local context; Suggestions to improve the use of CSRs. Data accuracy was checked by 2 independent evaluators. Ten HTA units participated. From their implementation a total of 321 HTA reports were published (49.8% included a SR). Works and services provided by the Cochrane collaboration were very well-known and HTA units were highly satisfied with CSRs (80%-100%). As regards to applicability in HTA and use of CSRs, major strengths were as follow: Useful as resource for search terms and background material; May reduce the workload (eg, brief review instead of full SR); Use to update a current review. Major weaknesses were: Limited use since no CSRs were available for many HTA projects; Difficulty to apply findings to local context; Focused only on efficacy and innocuity; Cannot be used as a substitute to a full HTA report. This study provided a unique context of assessment with a familiar group of producers, users and disseminators of CSRs in hospital setting. Since they generally used other articles from the literature or produce an original SR in complement with CSRs, this led to suggestions to improve their use of CSRs. However, the main limit for the use of CRS in local HTA will remain its lack of contextualisation. As such, this study reinforces the need to consider the notion of complementarity of experimental data informing us about causality and contextual data, allowing decision-making adapted to local issues.

Geographic access to mammography screening centre and participation of women in the Quebec Breast Cancer Screening Programme.

BACKGROUND: This study evaluated the impact of distance between women's residences and designated screening centres (DSC) on participation in the Quebec Breast Cancer Screening Programme, whether this impact varied according to the rural-urban classification and the proportion of participants who used the DSC nearest to their home. METHODS: Travel distance between the residence of 833 856 women and the nearest DSC (n=85) was estimated. Data were obtained from administrative and screening programme databases. The analysis made use of a log-binomial regression model adjusting for age and material and social deprivation. The proportions of participants who used the DSC nearest to their residence were measured. RESULTS: Compared to women living <2.5 km from a DSC, absolute decreases of 6.3% and 9.8% in participation rate were observed for distances of 50.0 to <75.0 km (rate ratios (RR)=0.88, 95% CI 0.86 to 0.89) and ≥75.0 km (RR=0.81, 95% CI 0.79 to 0.83), respectively. The lowest participation (42%) was observed in Montreal Island. The distance at which participation started to decrease materially varied according to rural-urban classification. Participation rates decreased at distances of ≥25.0 km in the Montreal suburbs and midsize cities, at ≥12.5 km in small cities and at ≥50.0 km in rural areas (interaction p<0.0001). The proportion of participants who had their mammography at the nearest DSC decreased with increasing distance. CONCLUSIONS: Distance affects participation and this effect varies according to rural-urban classification. The lower participation in Montreal Island, where all women lived <12.5 km from a DSC, argues for a major impact of other characteristics or other dimensions of accessibility.

Patient and public involvement in clinical practice guidelines: a knowledge synthesis of existing programs.

BACKGROUND: Reviewers independently extracted data on key components of PPIPs and barriers and facilitators to their operation. Data synthesis. Over half of the studies were published after 2002, and more than half originated from the United States, the United Kingdom, Australia, and Germany. CPGs that involved patients and the public addressed a variety of health problems, especially mental health and cancer. The most frequently cited objective for using PPIPs in developing CPGs was to incorporate patients' values or perspectives in CPG recommendations. Patients and their families and caregivers were the parties most often involved. METHODS: used to recruit PPIP participants included soliciting through patient/public organizations, sending invitations, and receiving referrals and recruits from clinicians. Patients and the public most often participated by taking part in a CPG working group, workshop, meeting, seminar, literature review, or consultation such as a focus group, individual interview, or survey. Patients and the public principally helped formulate recommendations and revise drafts. Limitations. The authors did not contact the authors of the studies. CONCLUSION: This literature review provides an extensive knowledge base for making PPIPs more effective when developing and implementing CPGs. More research is needed to assess the impact of PPIPs and resources they require.

Prenatal screening for Down syndrome: a survey of willingness in women and family physicians to engage in shared decision-making.

OBJECTIVE: To assess the willingness of women and their family physicians (FPs) to engage in shared decision-making (SDM) as regards prenatal Down-syndrome screening and the factors that might influence their willingness to do so. METHODS: We conducted a survey of participants in Québec City, Canada, using the theory of planned behavior. We used a general linear model and multilevel approach that took the fact that some women consulted the same FP into account. RESULTS: This study comprised 109 pregnant women and 41 FPs. On a scale of - 3 to + 3, the pregnant women's and FPs' response scores were, respectively, 2.11 ± 1.38 and 2.66 ± 0.40. In women, attitude, significant others, self-efficacy, perceived moral correctness, and their FP's attitude influenced their willingness to engage in SDM. However, women without a post-secondary education were less likely to engage in SDM than women with a post-secondary education, mostly because the former lacked a sense of self-efficacy. In FPs, only attitude and significant others influenced their willingness to engage in SDM. CONCLUSION: Overall, the women and their FPs wished to engage in SDM as regards prenatal Down-syndrome screening. Only a few factors influenced this desire which therefore may be modifiable.

Training family physicians in shared decision making for the use of antibiotics for acute respiratory infections: a pilot clustered randomized controlled trial.

BACKGROUND: Experts estimate that the prevalence of antibiotics use exceeds the prevalence of bacterial acute respiratory infections (ARIs). OBJECTIVE: To develop, adapt and validate DECISION+ and estimate its impact on the decision of family physicians (FPs) and their patients on whether to use antibiotics for ARIs. DESIGN: Two-arm parallel clustered pilot randomized controlled trial. SETTING AND PARTICIPANTS: Four family medicine groups were randomized to immediate DECISION+ participation (the experimental group) or delayed DECISION+ participation (the control group). Thirty-three FPs and 459 patients participated. INTERVENTION: DECISION+ is a multiple-component, continuing professional development program in shared decision making that addresses the use of antibiotics for ARIs. MAIN OUTCOME MEASURES: Throughout the pilot trial, DECISION+ was adapted in response to participant feedback. After the consultation, patients and FPs independently self-reported the decision (immediate use, delayed use, or no use of antibiotics) and its quality. Agreement between their decisional conflict was assessed. Two weeks later, patients assessed their decisional regret and health status. RESULTS: Compared to the control group, the experimental group reduced its immediate use of antibiotics (49 vs. 33% absolute difference = 16%; P = 0.08). Decisional conflict agreement was stronger in the experimental group (absolute difference of Pearson's r = 0.26; P = 0.06). Decisional regret and perceptions of the quality of the decision and of health status in the two groups were similar. DISCUSSION AND CONCLUSIONS: DECISION+ was developed successfully and appears to reduce the use of antibiotics for ARIs without affecting patients' outcomes. A larger trial is needed to confirm this observation.

Healthcare professionals' intentions to use wiki-based reminders to promote best practices in trauma care: a survey protocol.

BACKGROUND: Healthcare professionals are increasingly using wikis as collaborative tools to create, synthesize, share, and disseminate knowledge in healthcare. Because wikis depend on collaborators to keep content up-to-date, healthcare professionals who use wikis must adopt behaviors that foster this collaboration. This protocol describes the methods we will use to develop and test the metrological qualities of a questionnaire that will assess healthcare professionals' intentions and the determinants of those intentions to use wiki-based reminders that promote best practices in trauma care. METHODS: Using the Theory of Planned Behavior, we will conduct semi-structured interviews of healthcare professionals to identify salient beliefs that may affect their future use of wikis. These beliefs will inform our questionnaire on intended behavior. A test-retest of the survey will verify the questionnaire's stability over time. We will interview 50 healthcare professionals (25 physicians and 25 allied health professionals) working in the emergency departments of three trauma centers in Quebec, Canada. We will analyze the content of the interviews and construct and pilot a questionnaire. We will then test the revised questionnaire with 30 healthcare professionals (15 physicians and 15 allied health professionals) and retest it two weeks later. We will assess the internal consistency of the questionnaire constructs using Cronbach's alpha coefficients and determine their stability with the intra-class correlation (ICC). DISCUSSION: To our knowledge, this study will be the first to develop and test a theory-based survey that measures healthcare professionals' intentions to use a wiki-based intervention. This study will identify professionals' salient beliefs qualitatively and will quantify the psychometric capacities of the questionnaire based on those beliefs.

How much do family physicians involve pregnant women in decisions about prenatal screening for Down syndrome?

OBJECTIVE: To assess the extent to which family physicians (FPs) involve women in decisions about prenatal screening for Down syndrome. METHODS: Based on transcripts of consultations between 41 FPs and 128 women, two raters independently assessed clinician's efforts to involve women in decisions about prenatal screening for Down syndrome using the French-language version of OPTION. Descriptive statistics of OPTION scores were calculated. Construct validity was assessed by performing a principal factor analysis and by measuring association with consultation duration and FPs sociodemograhics. Internal consistency was assessed with Cronbach's alpha and inter-rater reliability with the intraclass correlation coefficient. RESULTS: The overall mean OPTION score was low: 19 +/- 7 (range = 0 [no involvement] to 100 [high involvement]). One factor accounted for 80% of the variance. Both internal consistency and inter-rater reliability were very good (Cronbach's alpha = 0.73; ICC = 0.76). OPTION scores were lower for residents than for licensed FPs (17 +/- 5 vs 21 +/- 4; p = 0.02) and were positively associated with duration of consultation (r = 0.56; p < 0.001). CONCLUSION: Based on the French-language version of OPTION, which showed satisfactory psychometric properties, FPs studied put minimal efforts to involve women in decisions about prenatal screening for Down syndrome.

Decisional needs assessment regarding Down syndrome prenatal testing: a systematic review of the perceptions of women, their partners and health professionals.

OBJECTIVE: To identify decisional needs of women, their partners and health professionals regarding prenatal testing for Down syndrome through a systematic review. METHODS: Articles reporting original data from real clinical situations on sources of difficulty and/or ease in making decisions regarding prenatal testing for Down syndrome were selected. Data were extracted using a taxonomy adapted from the Ottawa Decision-Support Framework and the quality of the studies was assessed using Qualsyst validated tools. RESULTS: In all 40 publications covering 32 unique studies were included. The majority concerned women. The most often reported sources of difficulty for decision-making in women were pressure from others, emotions and lack of information; in partners, emotion; in health professionals, lack of information, length of consultation, and personal values. The most important sources of ease were, in women, personal values, understanding and confidence in the medical system; in partners, personal values, information from external sources, and income; in health professionals, peer support and scientific meetings. CONCLUSION: Interventions regarding a decision about prenatal testing for Down syndrome should address many decisional needs, which may indeed vary among the parties involved, whether women, their partners or health professionals. Very little is known about the decisional needs of partners and health professionals.

Accuracy of nurse documentation of delirium symptoms in medical charts.

The purpose of this study undertaken in an acute care hospital was to evaluate sensitivity and specificity of the documentation of nurse-reported delirium symptoms in medical charts. This is a descriptive study based on the clinical assessments of a study nurse and nursing notes in the medical charts of 226 delirious older patients newly admitted to an acute care hospital. The results of this prospective validation study indicated that documentation of delirium symptoms is poor. Disorientation, agitation and altered level of consciousness were the three symptoms yielding a higher level of sensitivity, but even so said symptoms were reported in less than a third of the medical charts. Univariate analysis suggested that higher comorbidity level, more severe symptoms of delirium and the use of physical restraints were associated with more valid documentation of delirium symptoms in medical charts. Lastly, this study corroborates results of previous studies, indicating that documentation of delirium symptoms in medical charts can be improved. Future study should target improving nurse documentation of delirium symptoms in medical charts.

Translating shared decision-making into health care clinical practices: proof of concepts.

BACKGROUND: There is considerable interest today in shared decision-making (SDM), defined as a decision-making process jointly shared by patients and their health care provider. However, the data show that SDM has not been broadly adopted yet. Consequently, the main goal of this proposal is to bring together the resources and the expertise needed to develop an interdisciplinary and international research team on the implementation of SDM in clinical practice using a theory-based dyadic perspective. METHODS: Participants include researchers from Canada, US, UK, and Netherlands, representing medicine, nursing, psychology, community health and epidemiology. In order to develop a collaborative research network that takes advantage of the expertise of the team members, the following research activities are planned: 1) establish networking and on-going communication through internet-based forum, conference calls, and a bi-weekly e-bulletin; 2) hold a two-day workshop with two key experts (one in theoretical underpinnings of behavioral change, and a second in dyadic data analysis), and invite all investigators to present their views on the challenges related to the implementation of SDM in clinical practices; 3) conduct a secondary analyses of existing dyadic datasets to ensure that discussion among team members is grounded in empirical data; 4) build capacity with involvement of graduate students in the workshop and online forum; and 5) elaborate a position paper and an international multi-site study protocol. DISCUSSION: This study protocol aims to inform researchers, educators, and clinicians interested in improving their understanding of effective strategies to implement shared decision-making in clinical practice using a theory-based dyadic perspective.

Factors associated with delirium severity among older patients.

AIM: The goal of this study was to determine whether the factors associated with delirium varied according to the severity of the delirium experienced by the older patients. BACKGROUND: Delirium among older patients is prevalent and leads to numerous detrimental effects. The negative consequences of delirium are worse among older adults with severe delirium compared with patients with mild delirium. There has been no study identifying those factors associated with delirium severity among long-term care older patients newly admitted to an acute care hospital. DESIGN: This is a descriptive study. METHODS: This is a secondary analysis study of institutionalized older patients newly admitted to an acute care hospital (n = 104). Upon admission, patients were screened for delirium with the Confusion Assessment Method and severity of delirium symptoms were determined by using the Delirium Index. RESULTS: Of the 71 delirious older patients, 32 (45.1%) had moderate-severe delirium while 39 (54.9%) presented mild delirium. In univariate analyses, a significant positive relationship was observed between the level of prior cognitive impairment and the severity of delirium (p = 0.0058). Low mini-mental state examination (MMSE) scores (p < 0.0001), the presence of severe illness at the time of hospitalization (p = 0.0016) and low functional autonomy (BI: p = 0.0017; instrumental activities of daily living: p = 0.0003) were significantly associated with moderate-severe delirium. Older patients suffering from mild delirium used significantly more drugs (p = 0.0056), notably narcotics (p = 0.0017), than those with moderate-severe delirium. Results from the stepwise regression indicated that MMSE score at admission and narcotic medication use are the factors most strongly associated with the severity of delirium symptoms. CONCLUSIONS: This present study indicates that factors associated with moderate-severe delirium are different from those associated with mild delirium. Given the result concerning the role of narcotics, future studies should evaluate the role of pain management in the context of delirium severity. RELEVANCE TO CLINICAL PRACTICE: As moderate-severe delirium is associated with poorer outcomes than is mild delirium, early risk factor identification for moderate-severe delirium by nurses may prove to be of value in preventing further deterioration of those older patients afflicted with delirium.
