Users of NSAIDs are at approximately three times greater relative risk for developing serious adverse gastrointestinal events than are nonusers. Additional risk factors include age greater than 60 years, previous history of gastrointestinal events, and concomitant corticosteroid use. Another possible risk factor is the first 3 months of NSAID therapy. The risk for serious gastrointestinal events appears to be equal among men and women. These data represent summary statistics from 16 studies and cannot be considered generalizable to all NSAID users.

A worldwide epidemic of hip fractures has been predicted. Time trends in BMD testing, bone-sparing medications and hip and wrist fractures in the province of Ontario, Canada, were examined. From 1996 to 2001, BMD testing and use of bone-sparing medications increased each year, whereas despite the aging of the population, wrist and hip fracture rates decreased.Introduction: If patients with osteoporosis are being diagnosed and effective treatments used with increasing frequency in the population, rates of hip and wrist fractures will remain stable or possibly decrease. We report here time trends in BMD testing, prescriptions for bone-sparing medications, hip and wrist fracture rates, and population projections of fracture rates to 2005 in the province of Ontario, Canada. Materials and Methods: Ontario residents have universal access to Medicare. To examine time trends in BMD testing, all physician claims for DXA from 1992 to 2001 were selected from the Ontario Health Insurance Plan (OHIP) database. Trends in prescribing were examined from 1996 to 2003 using data from the Ontario Drug Benefit plan, which provides coverage to persons Ն65 years of age. Actual numbers of hip and wrist fractures were determined for 1992-2000 and population projections for 2001-2005 using time-series analysis. Wrist fractures were identified in the OHIP database and hip fractures through hospital discharge abstracts. Results: From 1992 to 2001, the number of BMD tests increased 10-fold. There has been a steady increase in the number of persons filling prescriptions for antiresorptives (12,298 in 1996 to 225,580 in 2003) and the majority were for etidronate. For women, the rate of decline for wrist fractures is greater than that for hip fractures. The rate of hip fracture was fairly constant around 41 per 10,000 women Ն50 years between 1992 and 1996. In 1997, the hip fracture rate began to decrease, and the population projections suggest that this downward trend will continue to a rate of 33.1 per 10,000 in 2005. Conclusions: Our findings suggest that fracture rates may be on the decline, despite the aging of the population, because of increased patterns of diagnosis and treatment for osteoporosis.

Objectives: This study explored the care challenges experienced by older patients with multimorbidity, their informal caregivers and family physicians. Approach: Semi-structured interviews were conducted with 27 patients, their informal caregivers and family physicians. Qualitative description was used to identify key themes in the interview transcripts. Results: Participants experienced many common challenges when managing multimorbidity, including a lack of decision-making support, poor communication and uncoordinated health services. Within these themes, unique perspectives specific to the role of being a patient, caregiver or family physician emerged. Conclusion: The study adds to a limited evidence base on the experience of patients with multimorbidity. By including the perspectives of their family caregivers and physicians, we provide important insight into the management of multimorbidity and recommend the uptake of specific strategies to address them. Résumé Objectif : Cette étude explore les défis vécus par les patients aînés en situation de multimorbidité, leurs aidants naturels et leurs médecins de famille. Démarche : Des entrevues semi-dirigées ont été menées auprès de 27 patients, de leurs aidants naturels et de leurs médecins de famille. Les principaux thèmes des transcriptions des entrevues ont été dégagés à l' aide d'une description qualitative. Résultats : Les participants éprouvent plusieurs défis communs dans la gestion de la multimorbidité, notamment un manque de soutien pour la prise de décision, de mauvaises communications et des services de santé non coordonnés. Parmi ces thèmes, il y a émergence de points de vue uniques propres aux rôles du patient, de l' aidant ou du médecin. Conclusion : L' étude s' ajoute au peu de données fondées sur l' expérience des patients en situation de multimorbidité. En incluant les points de vue des aidants naturels et des médecins, nous apportons des pistes importantes pour la gestion de la multimorbidité et nous recommandons l' adoption de stratégies particulières pour aborder la question.

Background: Epidemiological studies for identifying patients with Parkinson's disease (PD) or Parkinsonism (PKM) have been limited by their nonrandom sampling techniques and mainly veteran populations. This reduces their use for health services planning. The purpose of this study was to validate algorithms for the case ascertainment of PKM from administrative databases using primary care patients as the reference standard. Methods: We conducted a retrospective chart abstraction using a random sample of 73,003 adults aged ≥20 years from a primary care Electronic Medical Record Administrative data Linked Database (EMRALD) in Ontario, Canada. Physician diagnosis in the EMR was used as the reference standard and population-based administrative databases were used to identify patients with PKM from the derivation of algorithms. We calculated algorithm performance using sensitivity, specificity, and predictive values and then determined the population-level prevalence and incidence trends with the most accurate algorithms. Results: We selected, ‘2 physician billing codes in 1 year' as the optimal administrative data algorithm in adults and seniors (≥65 years) due to its sensitivity (70.6-72.3%), specificity (99.9-99.8%), positive predictive value (79.5-82.8%), negative predictive value (99.9-99.7%), and prevalence (0.28-1.20%), respectively. Conclusions: Algorithms using administrative databases can reliably identify patients with PKM with a high degree of accuracy.

In managing treatment for persons with mental illness, the primary care physician (PCP) needs to communicate with mental health (MH) professionals in various settings over time to provide appropriate management and continuity of care. However, effective communication between PCPs and MH specialists is often poor. The present study reviewed evidence on the quality of information transfer between PCPs and specialist MH providers for referral requests and after inpatient discharge. Twenty-three audit studies were identified that assessed the quality of content and nine that assessed strategies to improve quality. Results indicated that rates of item reporting were variable. Within the limited evidence on interventions to improve quality, use of structured forms showed positive results. Follow-up work can identify a minimum set of items to include in information transfers, along with item definitions and structures for holding this information. Then, methodologies for measuring data quality, including electronically generated performance metrics, can be developed.

MS patients can be accurately identified from administrative data. Our findings illustrated a rising prevalence of MS over time. MS incidence rates also appear to be rising since 2009.
