RESUMO

Background: Sarcopenia is associated with increased morbidity and mortality. Clinically, sarcopenia can be overlooked, especially in obesity. Sarcopenia diagnostic criteria include muscle mass (MM) and function assessments. Muscle function can be readily assessed in a clinic setting (grip strength, chair stand test). However, MM requires dual-energy X-ray absorptiometry (DXA) Body Composition (BC) or other costly tools, not readily available. Methods: Observational cohort pilot study of independently mobile, community dwelling older adults, comparing MM using two office-based, direct-to-consumer bioimpedance (BIA) scales (Ozeri® [manufactured in China] and OMRON® [OMRON HBF-510® Full Body Sensor, Shiokoji Horikawa, Kyoto, Japan] to DXA. The OMRON differs from the Ozeri scale because the OMRON also includes hand sensors. The European Working Group on Sarcopenia in Older People (EWGSOP) DXA or BIA low MM diagnostic cut-offs were used to classify participants as having low or normal MM. Results: Fifty participants: 11 men, 39 women. Forty-two completed DXA. Age 75.8 yrs [67-90]. 81% obese based on body fat cut-offs. With DXA [ASM/height2], 15 had low MM. Using BIA [mmass/height2], 7 with Ozeri, and 27 with OMRON, had low MM. Positive predictive value for low MM versus DXA (as the gold standard) for Ozeri was 73.3% and OMRON was 92.8%. Good correlation between BIA scales and DXA for body fat estimates. Conclusions: OMRON captured all low MM participants identified by DXA plus all on DXA diagnostic borderline. Prevalence of obesity was high. Clinically, sarcopenic obese is the most difficult phenotype, as obesity masks low muscle mass. Low cost, readily available, direct-to-consumer BIA BC scales, especially with hand sensors, provide immediate, reliable information on muscle and fat mass. This can prompt appropriate investigation and/or intervention for sarcopenia or sarcopenic obesity.

RESUMO

COVID-19 infection causes cognitive changes in the acute phase, but also after apparent recovery. Over fifty post (long)-COVID symptoms are described, including cognitive dysfunction ("brain fog") precluding return to pre-COVID level of function, with rates twice as high in females. Additionally, the predominant demographic affected by these symptoms is younger and still in the workforce. Lack of ability to work, even for six months, has significant socio-economic consequences. This cognitive dysfunction is associated with impaired cerebral glucose metabolism, assessed using 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET), showing brain regions that are abnormal compared to age and sex matched controls. In other cognitive conditions such as Alzheimer's disease (AD), typical patterns of cerebral glucose hypometabolism, frontal hypometabolism and cerebellar hypermetabolism are common. Similar FDG-PET changes have also been observed in post-COVID-19, raising the possibility of a similar etiology. Ketone bodies (B-hydroxybutyrate, acetoacetate and acetone) are produced endogenously with very low carbohydrate intake or fasting. They improve brain energy metabolism in the face of cerebral glucose hypometabolism in other conditions [mild cognitive impairment (MCI) and AD]. Long-term low carbohydrate intake or prolonged fasting is not usually feasible. Medium chain triglyceride (MCT) is an exogenous route to nutritional ketosis. Research has supported their efficacy in managing intractable seizures, and cognitive impairment in MCI and AD. We hypothesize that cerebral glucose hypometabolism associated with post COVID-19 infection can be mitigated with MCT supplementation, with the prediction that cognitive function would also improve. Although there is some suggestion that post COVID-19 cognitive symptoms may diminish over time, in many individuals this may take more than six months. If MCT supplementation is able to speed the cognitive recovery, this will impact importantly on quality of life. MCT is readily available and, compared to pharmaceutical interventions, is cost-effective. Research shows general tolerability with dose titration. MCT is a component of enteral and parenteral nutrition supplements, including in pediatrics, so has a long record of safety in vulnerable populations. It is not associated with weight gain or adverse changes in lipid profiles. This hypothesis serves to encourage the development of clinical trials evaluating the impact of MCT supplementation on the duration and severity of post COVID-19 cognitive symptoms.

RESUMO

INTRODUCTION: Osteoporosis is a major disease state associated with significant morbidity, mortality, and health care costs. Less than half of the individuals sustaining a low energy hip fracture are diagnosed and treated for the underlying osteoporosis. OBJECTIVE: A multidisciplinary Canadian hip fracture working group has developed practical recommendations to meet Canadian quality indicators in post hip fracture care. METHODS: A comprehensive narrative review was conducted to identify and synthesize key articles on post hip fracture orthogeriatric care for each of the individual sections and develop recommendations. These recommendations are based on the best evidence available today. CONCLUSION: Recommendations are anticipated to reduce recurrent fractures, improve mobility and healthcare outcomes post hip fracture, and reduce healthcare costs. Key messages to enhance postoperative care are also provided.

RESUMO

Catch a Break (CaB) is a secondary fracture prevention program that uses medical understandings of osteoporosis to assess first fractures and determine appropriateness for secondary fracture prevention. In this study, we interviewed CaB program participants to identify the understandings that patients themselves used to make sense of first fractures and the osteoporosis suggestion as cause. Semi-structured interviews were conducted with female and male participants of the CaB program in Canada. An interpretive practice approach was used to analyze the data. A random sample of 20 individuals, 12 women, and eight men all aged 50 years and over participated. First fractures were produced as meaningful in the context of osteoporosis only for seniors of very advanced age, and for people of any age with poor nutrition. The trauma events that led to a first fracture were produced as meaningful only if perceived as accidents, and having an active lifestyle was produced as beneficial only for mental health and well-being unrelated to osteoporosis. Cultural knowledge shapes, but does not determine, how individuals make sense of their health and illness experiences. Risk prevention program designers should include patients on the design team and be more aware of the presumptive knowledge used to identify individuals at risk of disease.

RESUMO

Introduction: Cerebral glucose and insulin metabolism is impaired in Alzheimer's disease (AD). Ketones provide alternative energy. Will medium chain triglyceride (MCT) oil, a nutritional source of ketones, impact cognition in AD? Methods: This was a 6-month randomized, double-blind, placebo-controlled, crossover study, with 6-month open-label extension in probable AD subjects, on stable medications. MCT dose was 42 g/day, or maximum tolerated. Cognition was assessed with Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Cognigram®. Results: Twenty subjects, average age 72.6 years, 45% women, 70% university educated had baseline MMSE 22.6/30 (10-29); MoCA 15.6/30 (4-27); baseline Cognigram® Part 1: 65-106, Part 2: 48-107. Average MCT oil consumption was 1.8 tablespoons/day (25.2 g, 234 kcal). Eighty percent remained stable or improved. Longer MCT exposure and age > 73, resulted in higher final MMSE (P < .001) and Cognigram® 1 scores. Discussion: This is the longest duration MCT AD study to date. Eighty percent had stabilization or improvement in cognition, and better response with 9-month continual MCT oil.

RESUMO

Catch a Break staff conducting the organizational work of delivering secondary fracture prevention screening conversations drew on cultural and organizational resources to determine eligibility of individuals. They encountered and navigated their way through interactional troubles as they requested participation, assessed trauma risk, and provided lifestyle information. PURPOSE: We investigated delivery of a population-based type C fracture liaison service for non-hip fractures. The purpose of this study was to examine accounts of how osteoporosis health risk screening interactions were delivered. METHODS: A pre-determined sample of 5 organizational representatives (program staff) were interviewed by telephone. We analyzed the qualitative data through the lens of interpretive inquiry, informed by discourse analysis, to examine staff's "talk" about conducting the program risk screening conversations. RESULTS: A dominant finding emerging from CAB staff's accounts of program delivery was the conversational work required to include only those individuals deemed appropriate for the program while managing the survey interaction. Staff talked about specific examples of interactional troubles they experienced as barriers to the smooth and successful risk screening conversation. They drew on cultural and organizational resources as interpretive frameworks to make decisions about individuals and groups at risk and in need of further investigation. They drew on larger ideas about ageism and genderism, judging as inappropriate for participation the oldest old adults, men involved in high risk occupations, and adults aged 50 to 70. Staff also employed interactional resources useful in managing problems in the conversation during the request to participate, trauma risk assessment, and lifestyle/health information provision sequences of the risk screening call. CONCLUSION: We uncovered areas in the screening interaction that were talked about by staff as problematic to achieving the program objective of identifying and enrolling individuals in the secondary fracture prevention program. By highlighting areas for improvement in program delivery, this study may help to reduce the interactional troubles staff negotiate as they deliver this type of program.

RESUMO

We assessed the context in which a hip Fracture Liaison Service was implemented. We conducted semi-structured interviews with 21 key informants at two time points to understand organizational readiness, facilitators, and barriers to change. We identified strategies important to successful implementation, particularly in the context of change fatigue. PURPOSE: Fracture Liaison Service (FLS) is effective for secondary fracture prevention. Two hospital sites implemented FLS for hip fracture patients, 50 + years, in Alberta, Canada. We assessed organizational readiness, facilitators, and barriers to change to better understand the context in which the FLS was implemented to inform its potential spread provincially. METHODS: We recruited individuals involved in FLS implementation at provincial and site levels to participate in telephone interviews at baseline and 16 months post-implementation. Interviews were transcribed and analyzed using thematic content analysis. In addition, site-level participants were invited to complete the Organizational Readiness to Implement Change tool at baseline. RESULTS: We conducted 33 semi-structured interviews (20 at baseline; 13 at post-implementation) with 21 key informants. Participants included managers (24%), FLS physicians/clinical nurses (19%), operational/leadership roles (19%), physicians/surgeons (14%), pharmacists (10%), nurse practitioners (10%), and social work (5%). Seventeen site-level participants completed the ORIC tool at baseline; all participants scored high (71%) or neutral (29%). We found that the use of several strategies, including demonstrating value, providing resources, and selecting appropriate sites, were important to implementation, particularly in the context of change fatigue. Participants perceived the FLS as acceptable and there was evidence of facilitated learning rather than simply monitoring implementation as intended. CONCLUSIONS: An effective change management approach neutralized change fatigue. This approach, if maintained, bodes well for the potential spread of the FLS provincially if proven effective and cost effective. Change readiness assessment tools could be used strategically to inform the spread of the FLS to early adopter sites.

RESUMO

Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent Clostridioides difficile infection. Stool donors are essential, but difficult to recruit and retain. We aimed to identify factors influencing willingness to donate stool. This multi-center study with a 32-item questionnaire targeted young adults and health care workers via social media and university email lists in Edmonton and Kingston, Canada; London and Nottingham, England; and Indianapolis and Boston, USA. Items included baseline demographics and FMT knowledge and perception. Investigated motivators and deterrents included economic compensation, screening process, time commitment, and stool donation logistics. Logistic regression and linear regression models estimated associations of study variables with self-assessed willingness to donate stool. 802 respondents completed our questionnaire: 387 (48.3%) age 21-30 years, 573 (71.4%) female, 323 (40%) health care workers. Country of residence, age and occupation were not associated with willingness to donate stool. Factors increasing willingness to donate were: already a blood donor (OR 1.64), male, altruism, economic benefit, knowledge of how FMT can help patients (OR 1.32), and positive attitudes towards FMT (OR 1.39). Factors decreasing willingness to donate were: stool collection unpleasant (OR 0.92), screening process invasive (OR 0.92), higher stool donation frequency, negative social perception of stool, and logistics of collection/transporting feces. We conclude that 1) blood donors and males are more willing to consider stool donation; 2) altruism, economic compensation, and positive feedback are motivators; and 3) screening process, high donation frequency, logistics of collection/transporting feces, lack of public awareness, and negative social perception are deterrents. Considering these variables could maximize donor recruitment and retention.

RESUMO

BACKGROUND: Malnutrition and sarcopenia are common in older adults. A new clinical syndrome has been suggested - the Malnutrition Sarcopenia Syndrome (MSS) - that may provide improved management, by highlighting two older adult conditions that can interact in a cumulative way to affect functional independence and health outcomes. This paper evaluates the published literature reporting data on both nutrition and sarcopenia evaluation simultaneously in the population studied, and creates a diagnostic algorithm. METHODS: An inclusive, systematic literature search was done for articles including a simultaneous standardised evaluation of sarcopenia and nutritional status, from 1990-date. Sarcopenic status needed to be evaluated using accepted guidelines published by international guideline committees which include a functional muscle evaluation and a quantitative evaluation using bioimpedence assay or dual energy X-ray absorptiometry. Nutritional status needed to evaluated with a standardised, validated nutritional screening tool that was not disease specific. RESULTS: 11 studies met these criteria. They differed in their methodology for screening both sarcopenia and nutritional issues. They differed as to the population studied (community versus institutionalised versus hospitalised). CONCLUSIONS: No one methodology was consistent for evaluation of sarcopenia or malnutrition. The concept of the Malnutrition Sarcopenia Syndrome intuitively makes sense to clinicians. This opinion paper suggests a possible clinical approach. The management and interventions for both conditions are likely to have considerable overlap. There needs to be some consensus on how to evaluate it, in order to be able to accurately interpret the impact of interventions that may be undertaken for one or both conditions simultaneously.

RESUMO

Subtrochanteric atypical femoral fractures (AFFs) have been reported in patients on osteoporosis therapy (bisphosphonates and denosumab). In 2010, and again in 2013, the ASBMR AFF Task Force developed strict diagnostic criteria for AFFs. This is the first study using these criteria to define the prevalence of AFFs in Canada. This study is a retrospective review of all adult patients (April 2002-March 2013) with an ICD 10 code for hip, femoral or subtrochanteric fracture, from two referral hospitals in Alberta, Canada. All identified as isolated subtrochanteric fractures were further evaluated by chart review, prescription review and examination of radiographs. Of 349 subjects, 79 had isolated subtrochanteric fractures. Of the 70 cases of subtrochanteric fractures that were radiographically assessed (9 films unavailable), 41 fulfilled ASBMR 2013 AFF criteria. The remaining subjects had subtrochanteric fractures but did not meet the ASBMR criteria to qualify as AFFs. There were 11 AFFs in 2012/2013, giving a rate of AFFs of 1.42 per 100,000 50 + year adults, compared to a rate of 103.47 per 100,000 50+ year adults for typical hip fractures. Isolated subtrochanteric fractures are rare. They cannot reliably be identified by ICD coding alone. In this study, only 59 % of all isolated subtrochanteric/femoral shaft fractures fulfilled the ASBMR task force criteria for true AFFs. The rate of typical hip fractures was substantially higher than the rate of AFFs, defined by ASBMR diagnostic criteria.

RESUMO

Dysphagia is a common problem in the elderly patient. Palato-pharyngo-laryngeal myoclonus, however, is a rare cause of this. We report a case of a 78-year-old man with dysphagia due to palato-pharngo-laryngeal myoclonus that was ultimately managed conservatively with a good functional outcome.

RESUMO

OBJECTIVE: To outline the efficacy and risks of bisphosphonate therapy for the management of osteoporosis and describe which patients might be eligible for bisphosphonate "drug holiday." QUALITY OF EVIDENCE: MEDLINE (PubMed, through December 31, 2012) was used to identify relevant publications for inclusion. Most of the evidence cited is level II evidence (non-randomized, cohort, and other comparisons trials). MAIN MESSAGE: The antifracture efficacy of approved first-line bisphosphonates has been proven in randomized controlled clinical trials. However, with more extensive and prolonged clinical use of bisphosphonates, associations have been reported between their administration and the occurrence of rare, but serious, adverse events. Osteonecrosis of the jaw and atypical subtrochanteric and diaphyseal femur fractures might be related to the use of bisphosphonates in osteoporosis, but they are exceedingly rare and they often occur with other comorbidities or concomitant medication use. Drug holidays should only be considered in low-risk patients and in select patients at moderate risk of fracture after 3 to 5 years of therapy. CONCLUSION: When bisphosphonates are prescribed to patients at high risk of fracture, their antifracture benefits considerably outweigh their potential for harm. For patients taking bisphosphonates for 3 to 5 years, reassess the need for ongoing therapy.

RESUMO

In this article, the authors present quality and safety standards for older people in hospital, derived from a national dialogue involving inter-professional experts, key stakeholders and opinion leaders. They report the consensus process and present the standard statements with corresponding operational definitions, along with relevant clinical topics. This work can serve as a platform for service planners, evaluators and policy makers who are endeavouring to ensure that older people receive quality care and service when admitted to a Canadian hospital.

RESUMO

The aging population is impacting subspecialty areas outside of geriatrics. Rheumatic diseases increase with age. Therapy for these diseases can add to polypharmacy and negatively impact other comorbidities. This is a retrospective chart review of all patients attending a rheumatology subspeciality clinic over 1 year. Referrals were prescreened and excluded probable degenerative axial and peripheral disease and chronic pain syndromes. Data were collected on demographics, diagnoses, and medications. Two hundred ninety-five new patients were seen. Seventy-eight (26%) were seniors (age, >65 years) with a mean age of 73 years (65-90). Comparing the >65 to <65 age groups, the prevalence of inflammatory arthritides (rheumatoid arthritis (RA), psoriatic arthritis, palindromic rheumatism) was comparable: 48% vs 53%; however, osteoarthritis and polymyalgia rheumatica were twice as common in the older group. Comorbidities in the >65 age group included hypertension (31%), osteoporosis (27%), diabetes (15%), hypothyroidism (11%), and coronary artery disease (9%). Only one patient had documented dementia. There were no cases of uncontrolled hypertension identified, and all patients were receiving a mixture of anti-hypertensives. Eighty-one percent of osteoporosis patients were on antiresorptives, but only 40% of prednisone users were taking bisphosphonates. For RA, treatment was somewhat comparable between the groups, with all but two patients receiving disease-modifying antirheumatic drugs. Eleven percent were on biologics. Seniors comprise a significant number of referrals. Pharmacotherapy differs in seniors, with more use of prednisone and a probable contribution of polypharmacy. This study highlights the need for reciprocal knowledge by both geriatricians and rheumatologists to optimize the management of these complex patients.

RESUMO

OBJECTIVE: To evaluate, in a real-world clinical setting, the efficacy of rivastigmine in the management of six symptoms commonly associated with Alzheimer's disease (AD). METHODS: This was a naturalistic, prospective, open-label, multi-centre, post-marketing, observational study. Data were collected by the participating study physicians at their practices across Canada. Subjects had a clinical diagnosis of mild-to-moderate AD and were prescribed rivastigmine by their treating physician. Efficacy was primarily evaluated by a physician-assessed, abbreviated Clinical Global Impression of Change (CGI-C) scale, focusing on six symptoms: attention, apathy, anxiety, agitation, irritability and sleep disturbance. Changes were assessed at months 3, 6 and 12. Several other patient-, physician- and caregiver-related assessments were also included. RESULTS: A total of 4460 patients were recruited by 353 study physicians; 3800 were deemed evaluable, having taken at least one dose of rivastigmine and with at least one post-baseline assessment. At baseline, attention problems were present in 86.0% of evaluable patients, anxiety in 77.3%, apathy in 68.3%, irritability in 64.0%, agitation in 54.6% and sleep disturbance in 54.5%. At both month 6 and month 12, for each symptom, the percentage of patients experiencing an improvement was considerably larger than the percentage of patients who experienced symptom worsening. Among evaluable patients, the proportions improving vs. deteriorating at month 6 were 46.4 vs. 8.8% for attention; 42.8 vs. 7.2% for apathy; 41.1 vs. 9.4% for anxiety; 33.8 vs. 7.7% for agitation; 35.1 vs. 10.1% for irritability; and 30.8 vs. 5.4% for sleep disturbance. LIMITATIONS: Open-label studies have an inherent potential for bias by both the caregiver and the physician. CONCLUSIONS: This study demonstrates that a considerable proportion of rivastigmine-treated patients experience improvements on each of the six symptoms studied. These findings add further support to previous randomised, clinical studies showing benefit of rivastigmine in AD.

RESUMO

Efficacy of hip protector pads to prevent hip fracture is controversial. This study was done to evaluate two comparable groups for fracture risk. Two matched cohorts of long-term care residents in Canada, assessing the efficacy of hip protector pads. Evaluation included demographics, medications/diagnoses, cognition (Mini Mental Status Examination (MMSE)), balance (Berg), bone mineral density (calcaneal ultrasound), falls/injuries at baseline and completion. Of the 58 participants, there were two confirmed hip fractures (8%) in the hip pad (one while wearing the pad) and eight (24%) in the control groups. But baseline demographics showed significant differences between hip pad (25) and control groups (33) in MMSE, Berg and osteoporosis treatment, all being less in the hip pad group. This persisted at completion, with a higher mortality in the hip pad group. Baseline differences predisposed the hip pad group to a higher fracture risk, but there were fewer hip fractures in this group. Small numbers, multifactorial nature of hip fractures and the inability to control for many of these variables in the real world make efficacy of hip protector pads difficult to confirm. Hip protector pads should be offered as part of the osteoporosis management of frail elderly, especially in those unable/unwilling to take pharmacotherapy.

RESUMO

OBJECTIVE: We previously demonstrated that a case manager intervention improved osteoporosis (OP) treatment within 6 months of hip fracture compared with usual care. The second phase of the randomized trial compared a less intensive intervention, facilitated bone mineral density (BMD) testing, with usual care and the case manager intervention. METHODS: We initially randomized 220 hip fracture patients to either an OP case manager intervention or usual care. After completing the original trial at 6 months postfracture, usual care patients were reallocated to facilitated BMD testing; BMD tests were arranged and results sent to primary care physicians. Main outcomes (bisphosphonate treatment, BMD tests, receipt of appropriate care) were reascertained 1 year following hip fracture and compared with outcomes achieved by the OP case manager intervention and usual care. RESULTS: Compared with usual care, facilitated BMD testing increased testing from 29% to 68% (P < 0.001), bisphosphonate use from 22% to 38% (P < 0.001), and receipt of appropriate care from 26% to 45% (P < 0.001). The more intensive (70 versus 30 minutes) and expensive ($56 versus $24 Canadian per patient) OP case manager intervention led to significantly higher bisphosphonate use (54% versus 38%; P = 0.03), receipt of appropriate care (71% versus 45%; P < 0.001), and more BMD testing (80% versus 68%; P = 0.06) than usual care followed by facilitated BMD testing. CONCLUSION: Compared with usual care, 2 different inexpensive interventions resulted in significant increases in appropriate management of OP after hip fracture. The magnitude of improvements achieved was directly related to the intensity of the interventions.

RESUMO

BACKGROUND: In a randomized trial of patients with hip fractures, we previously demonstrated that a hospital-based case manager could increase rates of appropriate osteoporosis treatment to 51% compared with 22% for usual care (P < .001). Alongside that trial, we conducted an economic analysis. METHODS: Patients with hip fractures were randomized to usual care (n = 110) or a case manager (n = 110) and followed up for 1 year. Time-motion studies were used to determine intervention costs. From a third-party health care payer perspective and over the patient's remaining lifetime, a Markov decision-analytic model was constructed to determine cost-effectiveness of the intervention compared with usual care. Costs and benefits were discounted at 3% and expressed in 2006 Canadian dollars. RESULTS: The intervention cost CaD $56 per patient. Compared with usual care, the intervention strategy was dominant: for every 100 patients case managed, 6 fractures (4 hip fractures) were prevented, 4 quality-adjusted life-years were gained, and CaD $260 000 was saved by the health care system. Irrespective of the number of patients case managed, the intervention reached a break-even threshold within 2 years. The intervention dominated usual care over the entire spectrum of 1-way sensitivity analyses and was cost-saving in 82% of probabilistic model simulations. CONCLUSIONS: Compared with usual care, we found that using a case manager for patients with hip fractures increased rates of appropriate osteoporosis treatment. The intervention dominated usual care, and the analysis suggests that systems implementing an intervention similar to ours should expect to see a reduction in fractures, gains in life expectancy, and substantial cost savings.

RESUMO

Canadian Consensus guidelines regarding appropriate use of nonsteroidal anti-inflammatory drugs (NSAID) were recently published. This study was done to evaluate the application of these guidelines on NSAID practice patterns in frail elderly patients referred to a specialist Geriatric Assessment Clinic. A retrospective chart review was undertaken of referrals who were currently prescribed NSAIDs. Data were captured on age, sex, weight, diagnoses, medications and dosages, indication for NSAID treatment, lying BP (as assessed in the clinic) and recent serum creatinine result. Creatinine clearance was subsequently calculated use the Cockcroft-Gault equation. Complete data were available on 107 patients (68% women, average age 80.6 years). Thirty percent were on a traditional NSAID, the remainder were on a Coxib. Concomitant aspirin was prescribed in 37%. Cytoprotection was being used in 38% and did not increase appreciably in patients with additional risk factors for GI toxicity, i.e., concomitant aspirin usage (35%), and history of GI toxicity (48%). Sixty-seven were taking anti-hypertensive medications, although more than two thirds of these patients were uncontrolled. Newly diagnosed hypertension was present in 19.6%. Calculated creatinine clearance revealed moderate to severe renal impairment in 79% of subjects, although serum creatinine was only elevated in 18%. In total, 70% of subjects were found to have relative or absolute risk factors for NSAID therapy. Given the high prevalence of potential contraindications to anti-inflammatory drug usage in this study, we advocate the dissemination and application of these guidelines in geriatric patients in an attempt to reduce potential morbidity and mortality.
