Background: The use of computerized clinical decision support systems (CCDSSs) may improve chronic disease management, which requires recurrent visits to multiple health professionals, ongoing disease and treatment monitoring, and patient behavior modification. The objective of this review was to determine if CCDSSs improve the processes of chronic care (such as diagnosis, treatment, and monitoring of disease) and associated patient outcomes (such as effects on biomarkers and clinical exacerbations).

Methods: We conducted a decision-maker-researcher partnership systematic review.

Background: Acute medical care often demands timely, accurate decisions in complex situations. Computerized clinical decision support systems (CCDSSs) have many features that could help. However, as for any medical intervention, claims that CCDSSs improve care processes and patient outcomes need to be rigorously assessed.

Background: Some drugs have a narrow therapeutic range and require monitoring and dose adjustments to optimize their efficacy and safety. Computerized clinical decision support systems (CCDSSs) may improve the net benefit of these drugs. The objective of this review was to determine if CCDSSs improve processes of care or patient outcomes for therapeutic drug monitoring and dosing.

Background: Computerized clinical decision support systems (CCDSSs) for drug therapy management are designed to promote safe and effective medication use. Evidence documenting the effectiveness of CCDSSs for improving drug therapy is necessary for informed adoption decisions. The objective of this review was to systematically review randomized controlled trials assessing the effects of CCDSSs for drug therapy management on process of care and patient outcomes.

Background: Underuse and overuse of diagnostic tests have important implications for health outcomes and costs. Decision support technology purports to optimize the use of diagnostic tests in clinical practice. The objective of this review was to assess whether computerized clinical decision support systems (CCDSSs) are effective at improving ordering of tests for diagnosis, monitoring of disease, or monitoring of treatment.

Background: Computerized clinical decision support systems (CCDSSs) are claimed to improve processes and outcomes of primary preventive care (PPC), but their effects, safety, and acceptance must be confirmed. We updated our previous systematic reviews of CCDSSs and integrated a knowledge translation approach in the process. The objective was to review randomized controlled trials (RCTs) assessing the effects of CCDSSs for PPC on process of care, patient outcomes, harms, and costs.

Goal Of Work: The goal of this work was to identify methods of clinician-patient cancer-related communication that may impact patient outcomes associated with distress at critical points in the course of cancer care.

Materials And Methods: A systematic review of practice guidelines, systematic reviews, or randomized trials on this topic was conducted. Guidelines for quality was evaluated using the Appraisal of Guidelines for Research and Evaluation Instrument, and the contributive value for recommendations was assessed.

Goals Of Work: The goal of the study is to evaluate the effectiveness of four drug classes (opioids, phenothiazines, benzodiazepines, and systemic corticosteroids) for relieving dyspnea experienced by advanced cancer patients.

Materials And Methods: A systematic literature review was conducted to July 2006. Search sources included MEDLINE, EMBASE, HealthSTAR, CINAHL, and the Cochrane Library.

Introduction: Inhibition of the epidermal growth factor receptor is a promising therapy in the treatment of non-small cell lung cancer (NSCLC). In this systematic review, we evaluated the role of the epidermal growth factor receptor inhibitors gefitinib and erlotinib in the treatment of patients with advanced NSCLC.

Methods: Relevant randomized trials published as articles or abstracts were identified through a systematic search of the literature from 1975 to November 2005 by two independent reviewers.

Purpose: Practitioner feedback (PF) surveys are sent to practitioners who care for lung cancer patients as each new practice guideline is completed. In this study, the PF was reviewed to assess the frequency of response to the surveys, the respondents' characteristics, the nature of the feedback, and the intention to adopt the guideline in practice.

Methods: Fourteen practice guidelines (PGs) were sent to Ontario practitioners treating lung cancer, and feedback on the PGs was obtained through either an eight- or 21-item survey.

Goals Of The Work: To evaluate the efficacy of pharmacological and nonpharmacological treatments for depression in cancer populations.

Materials And Methods: The Supportive Care Guidelines Group conducted a systematic review of the published literature through June 2005. Search sources includes MEDLINE, EMBASE, CINAHL, PsycInfo, and the Cochrane Library.

A systematic review of the evidence for postoperative chemotherapy in completely resected nonsmall cell lung cancer was conducted. Seven meta-analyses and 25 randomized trials met the pre-defined eligibility criteria for the review. The evidence indicates that postoperative platinum-based chemotherapy improves survival compared with surgery alone; for patients with a good performance status who are fit enough for chemotherapy, the survival benefits strongly outweigh the adverse effects of treatment.

Purpose: To conduct a systematic review and to evaluate the impact of postoperative adjuvant chemotherapy on the survival of patients with completely resected non-small cell lung cancer.

Methods: Relevant randomized trials and meta-analyses, published as articles or abstracts, were identified through electronic and hand searches by two reviewers.

Results: Seven meta-analyses and 26 randomized trials comparing surgery with or without chemotherapy met the pre-defined eligibility criteria for the review.

Unlabelled: This evidence-based practice guideline on the use of paclitaxel (Taxol) or docetaxel (Taxotere) as first-line treatment for patients with advanced non-small cell lung cancer who are candidates for palliative first-line chemotherapy is based on a systematic search and review of literature published in full or in abstract form between 1985 and April 2005. Forty-five randomized trials, including 11 abstracts, were reviewed and clinicians in the province of Ontario, Canada, provided feedback on a draft version of the guideline. Two phase III trials detected a statistically significant survival advantage for a taxane (paclitaxel or docetaxel) with best supportive care versus best supportive care alone.

Unlabelled: An evidence summary was developed for the surgical management of adult patients with diffuse or localized malignant pleural mesothelioma. This evidence summary is based on a systematic search and review of the literature published between 1985 and February 2004. Relevant studies were identified, according to pre-determined criteria by the authors and methodologists.

Unlabelled: The Lung Cancer Disease Site Group of Cancer Care Ontario's Program in Evidence-based Care conducted a systematic review of literature published between 1985 and July 2003 and developed an evidence-based clinical practice guideline on postoperative radiotherapy in patients with completely resected pathologic stage II or IIIA non-small cell lung cancer (NSCLC). Forty-four Ontario clinicians reviewed the draft guideline. Evidence included one meta-analysis of individual patient data (from nine randomized controlled trials) and three randomized controlled trials (two including data reported in the meta-analysis) that compared surgery with or without postoperative radiotherapy.

Unlabelled: An evidence-based practice guideline was developed to identify the optimal combination chemotherapy regimen, schedule of administration, and duration of therapy for the first-line treatment of adults with limited-stage small-cell lung cancer. The guideline is based on a systematic search and review of literature published between 1985 and December 2002. Three reviewers selected studies for inclusion in the guideline according to pre-defined criteria.
