Estimating the number of coronary artery bypass graft and percutaneous coronary intervention procedures in Canada: a comparison of cardiac registry and Canadian Institute for Health Information data sources.

Background: Provincial cardiac registries and the Canadian Institute for Health Information (CIHI) pan-Canadian administrative databases are invaluable tools for understanding Canadian cardiovascular health and health care. Both sources are used to enumerate cardiovascular procedures performed in Canada.

Objective: To examine the level of agreement between provincial cardiac registry data and CIHI data regarding procedural counts for coronary artery bypass grafts (CABGs) and percutaneous coronary interventions (PCIs).

Oral health-related quality of life of children with oligodontia.

Objectives: To assess the functional and psychosocial impact of oligodontia in children aged 11-14 years.

Methods: Children aged 11-14 years with oligodontia were recruited from orthodontic clinics when they presented for orthodontic evaluation. All completed a copy of the Child Perceptions Questionnaire for 11- to 14-year olds, a measure of the functional and psychosocial impact of oral disorders.

Day surgery visits for dental problems.

Objectives: To fill an information gap for dental care policy stakeholders in Canada, this pilot study explored the nature of day surgery (DS) visits for dental problems in Ontario, the country's largest province.

Methods: The Canadian Institute for Health Information's National Ambulatory Care Reporting System was used, which contains demographic, diagnostic, procedural and administrative information for ambulatory care settings across Ontario. Fiscal years 2003/2004 to 2005/2006 data were included for DS visits that had a main problem coded with an International Classification of Diseases code in the range K00-K14, representing diseases of the oral cavity, salivary glands and jaws.

Emergency department visits for dental care of nontraumatic origin.

Objectives: To explore the nature of emergency department (ED) visits for dental problems of nontraumatic origin in Canada's largest province, Ontario.

Methods: The Canadian Institute for Health Information's National Ambulatory Care Reporting System was used, which contains demographic, diagnostic, procedural and administrative information from hospital-based ambulatory care settings across Ontario. Data of fiscal years 2003/04 to 2005/06 were included for emergency visits that had a main problem coded with an International Classification of Diseases - 10th edition code in the range K00-K14, representing diseases of the oral cavity, salivary glands and jaws.

Direction of wording and responses to items in oral health-related quality of life questionnaires for children and their parents.

Objectives: In order to minimize acquiescence response set bias, it is often recommended that questionnaires measuring attitudes, behaviours or health states contain items worded positively and negatively. It has also been suggested that when measuring health status this approach means that both the negative and positive dimensions of health can be assessed. This study aimed at assessing the performance of negatively and positively worded items in questionnaires to measure child and parent perceptions of child oral health-related quality of life.

Is the Child Perceptions Questionnaire for 11-14 year olds sensitive to clinical and self-perceived variations in orthodontic status?

Objectives: To assess the association between scores on the Child Perceptions Questionnaire for 11-14 year olds (CPQ11-14) and clinical and self-perceived measures of malocclusion.

Methods: Children were recruited from an orthodontic clinic just prior to starting orthodontic treatment. They completed a copy of the CPQ11-14 and a short questionnaire concerning their feelings about the condition of their teeth.

Does self-weighting of items enhance the performance of an oral health-related quality of life questionnaire?

Objectives: To determine if self-weighting of the items in an oral health-related quality of life questionnaire improves its psychometric properties.

Methods: The Surgical Orthodontic Outcome Questionnaire (SOOQ) was designed to assess the oral health-related quality of life of individuals before and after corrective surgery. Each of its 33 'items' consists of two questions: a question concerning the frequency with which a given functional or psychosocial problem had been experienced and a 'weighting' question which asked about how much the individual was bothered by that problem.

Missed opportunity: patients who leave emergency departments without being seen.

The rate of patients who visit emergency departments (EDs) but leave before being evaluated and treated is an important indicator of ED performance. This study examines patient- and hospital-level characteristics that may increase the risk of patients leaving EDs before being seen. The data are from the National Ambulatory Care Reporting System, an administrative database, and represent 4.

Short forms of the Child Perceptions Questionnaire for 11-14-year-old children (CPQ11-14): development and initial evaluation.

Background: The Child Perceptions Questionnaire for children aged 11 to 14 years (CPQ11-14) is a 37-item measure of oral-health-related quality of life (OHRQoL) encompassing four domains: oral symptoms, functional limitations, emotional and social well-being. To facilitate its use in clinical settings and population-based health surveys, it was shortened to 16 and 8 items. Item impact and stepwise regression methods were used to produce each version.

Bariatric surgery in Canada: obesity rates for Canadian adults are much higher today than in the past; however, rates of bariatric surgery, a treatment for high-risk severely obese individuals, have not risen in parallel.

Obesity rates for Canadian adults are much higher today than in the past, raising questions about how to achieve healthy weights and mitigate the associated health risks. While not a solution at the population level, bariatric surgery may be a treatment option for a relatively small proportion of obese individuals. In Canada, unlike in the United States, no consistent trend was evident in the use of this surgery between 1996-97 and 2003-04 across the five provinces for which comparable data were available.

What do older adults' global self-ratings of oral health measure?

Objective: Although global self-ratings of oral health are widely used in oral health research, the frames of reference on which older people's ratings are based are not known. This study used a quantitative approach in order to identify these referents.

Methods: Data were collected from 498 dentate subjects aged 53 years and over who took part in the second stage of a three-phase longitudinal epidemiological and sociodental study.

Health-related quality of life of children aged 11 to 14 years with orofacial conditions.

Objective: To assess the health-related quality of life (HRQoL) of 11- to 14-year-old children with orofacial conditions.

Design: Thirty-nine patients with orofacial conditions were compared with 32 patients with dental caries.

Outcome Measure: The multidimensional 37-item Child Perceptions Questionnaire for 11- to 14-year-old children (CPQ(11-14)).

What do children's global ratings of oral health and well-being measure?

Objectives: To explore the constructs children incorporate in the responses to global ratings of their oral health (OH) and OH-related overall well-being (OWB).

Methods: Data were collected as part of a project to validate the Child Perceptions Questionnaire for ages 11-14 (CPQ11-14), a self-report measure of OH-related quality of life. Its 37 questions are organized in the symptoms, functional limitations, emotional and social well-being domains.

Questionnaire for measuring oral health-related quality of life in eight- to ten-year-old children.

Purpose: This study measured oral health-related quality of life for children, which involved the construction of child perceptions questionnaires (CPQs) for ages 6 to 7, 8 to 10, and 11 to 14. The purpose of this study was to present the development and evaluation of the CPQ for 8- to 10-year-olds (CPQ8-10).

Methods: Questions (N=25) were selected from the CPQ for 11- to 14-year-olds based on the child development literature and input from parents, child psychologist, and teacher of grades 3 and 4.

Assessing the responsiveness of measures of oral health-related quality of life.

Objectives: This paper illustrates ways of assessing the responsiveness of measures of oral health-related quality of life (OHRQoL) by examining the sensitivity of the oral health impact profile (OHIP)-14 to change when used to evaluate a dental care program for the elderly.

Methods: One hundred and sixteen elderly patients attending four municipally funded dental clinics completed a copy of the OHIP-14 prior to treatment and 1 month after the completion of treatment. The post-treatment questionnaire also included a global transition judgement that assessed subjects' perceptions of change in their oral health following treatment at the clinics.

Agreement between mothers and children aged 11-14 years in rating child oral health-related quality of life.

Objectives: To assess the agreement between mothers and children concerning the child's oral health-related quality of life.

Methods: A total of 42 pairs of mothers and children aged 11-14 years with oral and orofacial conditions completed the parental (PPQ) and child (CPQ(11-4)) components of the Child Oral Health Quality of Life Questionnaire. The PPQ and CPQ(11-14) are analogous questionnaires with 31 common items.
