Community-based care for chronic wound management: an evidence-based analysis.
In August 2008, the Medical Advisory Secretariat (MAS) presented a vignette to the Ontario Health Technology Advisory Committee (OHTAC) on a proposed targeted health care delivery model for chronic care. The proposed model was defined as multidisciplinary, ambulatory, community-based care that bridged the gap between primary and tertiary care, and was intended for individuals with a chronic disease who were at risk of a hospital admission or emergency department visit. The goals of this care model were thought to include: the prevention of emergency department visits, a reduction in hospital admissions and re-admissions, facilitation of earlier hospital discharge, a reduction or delay in long-term care admissions, and an improvement in mortality and other disease-specific patient outcomes.OHTAC approved the development of an evidence-based assessment to determine the effectiveness of specialized community based care for the management of heart failure, Type 2 diabetes and chronic wounds.PLEASE VISIT THE MEDICAL ADVISORY SECRETARIAT WEB SITE AT: www.health.gov.on.ca/ohtas to review the following reports associated with the Specialized Multidisciplinary Community-Based care series.Specialized multidisciplinary community-based care series: a summary of evidence-based analysesCommunity-based care for the specialized management of heart failure: an evidence-based analysisCommunity-based care for chronic wound management: an evidence-based analysisPlease note that the evidence-based analysis of specialized community-based care for the management of diabetes titled: "Community-based care for the management of type 2 diabetes: an evidence-based analysis" has been published as part of the Diabetes Strategy Evidence Platform at this URL: http://www.health.gov.on.ca/english/providers/program/mas/tech/ohtas/tech_diabetes_20091020.htmlPLEASE VISIT THE TORONTO HEALTH ECONOMICS AND TECHNOLOGY ASSESSMENT COLLABORATIVE WEB SITE AT: http://theta.utoronto.ca/papers/MAS_CHF_Clinics_Report.pdf to review the following economic project associated with this series:Community-based Care for the specialized management of heart failure: a cost-effectiveness and budget impact analysis. ⋯ The evidence supports that managing chronic wounds with a multidisciplinary wound care team significantly increases wound healing and reduces the severity of wound-associated pain and the required daily wound treatments compared to persons not managed by a wound care team. The quality of evidence supporting these outcomes is low to very low meaning that further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

Intraocular lenses for the treatment of age-related cataracts: an evidence-based analysis.
The objective of the report is to examine the comparative effectiveness and cost-effectiveness of various intraocular lenses (IOLs) for the treatment of age-related cataracts. ⋯ The conclusions of the systematic review of IOLs for age-related cataracts are summarized in Executive Summary Table 1. CONSIDERATIONS FOR THE ONTARIO HEALTH SYSTEM: Procedures for crystalline lens removal and IOL insertion are insured and listed in the Ontario Schedule of Benefits.If a particular lens is determined to be medically necessary for a patient, the cost of the lens is covered by the hospital budget. If the patient chooses a lens that has enhanced features, then the hospital may choose to charge an additional amount above the cost of the usual lens offered.An IOL manufacturer stated that monofocal lenses comprise approximately 95% of IOL sales in Ontario and premium lenses (e.g., multifocal/accomodative) consist of about 5% of IOL sales.A medical consultant stated that all types of lenses are currently being used in Ontario (e.g., multifocal, monofocal, accommodative, tinted, nontinted, spheric, and aspheric). Nonfoldable lenses, rarely used in routine cases, are primarily used for complicated cataract implantation situations.ES Table 1:Conclusions for the Systematic Review of IOLs for Age-Related CataractsComparisonConclusionGRADE QualityMultifocal vs. monofocalObjective OutcomesSignificant improvement in BDCUNVANo significant difference in BCDVAInconclusive evidence for contrast sensitivityInconclusive evidence for glareSubjective OutcomesInconclusive evidence for visual satisfactionSignificant increase in glare/halosSignificant increase in freedom from spectaclesmoderatemoderatelowvery lowlowlow/moderatelow/moderateAccommodative vs. multifocal/monofocalInconclusive due to Insufficient limited evidence for any effectiveness outcomevery lowHydrophilic acrylic vs. other materials (hydrophobic acrylic, silicone)Significant increase in PCO scoreLowSharp edged compared to round edgedSignificant reduction in PCO scoreLowOne piece compared to three pieceNo significant difference in PCO scorelowHydrophobic acrylic compared to siliconeNo significant difference in PCO scoremoderateAspherical modified prolate anterior surface compared to sphericalNo significant difference in VASignificant reduction in contrast sensitivityvery lowvery lowBlue light filtering compared to non blue-light filteringNo significant difference in BCDVANo significant difference in contrast sensitivityNo significant difference in HRQLlowlowhigh/moderateBCDVA refers to best corrected distance visual acuity; BDCUNVA, best distance corrected unaided near visual acuity; HRQL, health related quality of life; PCO, posterior capsule opacification; VA, visual acuity.

Behavioural interventions for urinary incontinence in community-dwelling seniors: an evidence-based analysis.
In early August 2007, the Medical Advisory Secretariat began work on the Aging in the Community project, an evidence-based review of the literature surrounding healthy aging in the community. The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry's newly released Aging at Home Strategy.After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person's transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.AGING IN THE COMMUNITY: Summary of Evidence-Based AnalysesPrevention of Falls and Fall-Related Injuries in Community-Dwelling Seniors: An Evidence-Based AnalysisBehavioural Interventions for Urinary Incontinence in Community-Dwelling Seniors: An Evidence-Based AnalysisCaregiver- and Patient-Directed Interventions for Dementia: An Evidence-Based AnalysisSocial Isolation in Community-Dwelling Seniors: An Evidence-Based AnalysisThe Falls/Fractures Economic Model in Ontario Residents Aged 65 Years and Over (FEMOR) OBJECTIVE: To assess the effectiveness of behavioural interventions for the treatment and management of urinary incontinence (UI) in community-dwelling seniors. ⋯ A budget impact analysis was conducted to forecast costs for caregiver-dependent and patient-directed multicomponent behavioural techniques delivered by NCAs, and PFMT alone delivered by physiotherapists.
