Drug utilization review of celecoxib in Ontario.

Cyclooxygenase (COX)-2-specific inhibitors were developed to circumvent the gastrointestinal toxicity of non-specific non-steroidal anti-inflammatory drugs while maintaining efficacy. However, the higher acquisition cost of COX-2-specific inhibitors has resulted in the implementation of a programme for cost containment in the Ontario public drug program. This programme consists of limited use (LU) criteria that need to be met for drug reimbursement of patients with osteoarthritis (OA) or rheumatoid arthritis (RA). Determining the proportion of patients eligible for reimbursement for celecoxib according to the LU criteria (based on prior treatment failure and the presence or history of serious ulcer-related gastrointestinal complications) can provide an indication of the extent of adherence to suggested guidelines. Using a patient-based survey and an analysis of the Ontario Drug Benefit Program database, the proportion of patients prescribed celecoxib who met rigorous or pragmatic definitions of the LU criteria was determined. The extent of coprescription of gastroprotective agents among patients taking celecoxib was also determined. Using the pragmatic definition, the majority of patients in the patient-based survey (53% for OA and 81% for RA) met the LU criteria. Similarly, in the database analysis, the majority of patients (76% for OA and 78% for RA) met the LU criteria. These data suggest that physician prescribing of celecoxib is consistent with the LU criteria. Concomitant prescription of gastroprotective agents in patients taking celecoxib was approximately 40%. It is recommended that further investigations be performed to determine the long-term impact of LU criteria on clinical and economic outcomes, since these criteria may also serve to restrict use in patients who may benefit from taking COX-2-specific inhibitors.

Do statins cause cancer? A meta-analysis of large randomized clinical trials.

PURPOSE: Although the short-term safety and tolerability of statins has been well established, their potential carcinogenicity in the long term is still debated. The goal of this study was to determine whether long-term treatment with statins is associated with an increased risk of fatal and nonfatal cancers. METHODS: We searched the Medline database between January 1966 and December 1999 for randomized, controlled trials of human subjects in which monotherapy with a statin was compared with placebo. No language restrictions were applied. Only trials with a minimum treatment duration of 4 years and a minimum of 1,000 subjects were included. Studies that did not provide information on fatal or nonfatal cancers were excluded. Data on fatal and nonfatal cancers and all-cause mortality were extracted by a single nonblinded reviewer. Overall crude estimates of risk difference were computed by summing the numerators and denominators of trial-specific risk estimates. RESULTS: Five trials met the inclusion criteria. The estimated differences in absolute risk between treatment and placebo were as follows (negative risks indicate that treatment was safer than placebo): all nonfatal cancers, 0.0% (95% confidence interval [CI]: -0.8% to 0.8%); all fatal cancers, -0.1% (95% CI: -0.7% to 0.4%); all fatal and nonfatal cancers combined, -0.1% (95% CI: -1.0% to 0.7%); and all-cause mortality, -1.5% (95% CI: 2.8% to 0.2%). CONCLUSION: This study demonstrates no association between statin use over a 5-year period and the risk of fatal and nonfatal cancers. This conclusion is limited by the relatively short follow-up of the studies analyzed. Similar analyses of data from studies with longer follow-up periods would be valuable.

Age-related differences in in-hospital mortality and the use of thrombolytic therapy for acute myocardial infarction.

BACKGROUND: Recent guidelines have acknowledged that thrombolysis decreases mortality from acute myocardial infarction (AMI) independently of age. The purpose of this study was to determine the age-related rates of thrombolytic administration and in-hospital mortality and the variables related to the use of thrombolytic therapy for patients with AMI. METHODS: A prospective cohort analysis involved a registry of 44 acute care Quebec hospitals that enrolled 3741 patients with AMI between January 1995 and May 1996. The main outcomes of interest were crude and adjusted age-related in-hospital mortality rates and rates of use of thrombolytic therapy. RESULTS: In-hospital mortality rates increased dramatically with age from 2.1% in patients with AMI who were less than 55 years of age to 26.3% in those who were 85 years of age or older. Overall, 35.8% of the patients received thrombolysis. There was a pronounced inverse gradient in the use of thrombolysis with age, ranging from 46.2% in the youngest age group (< 55 years) to 9.5% in the oldest group (> or = 85 years). After adjustment for potential confounders, the older patients remained significantly less likely to receive thrombolytic therapy. Compared with patients who were less than 55 years of age, the odds ratio of receiving thrombolytic therapy was 0.68 (95% confidence interval [CI] 0.52-0.89) for patients aged 65-74 years, 0.48 (95% CI 0.35-0.65) for patients aged 75-84 years and 0.13 (95% CI 0.06-0.26) for patients aged 85 years or more. Other variables related to thrombolytic therapy were diabetes (odds ratio [OR] 0.77, 95% CI 0.59-1.00), cerebrovascular disease (OR 0.46, 95% CI 0.30-0.72), angina (OR 0.73, 95% CI 0.56-0.95), typical chest pain (OR 2.56, 95% CI 1.88-3.47); ST elevation (OR 8.93, 95% CI 7.24-11.00), Q wave MI (OR 5.26, 95% CI 4.20-6.60) and increased length of time between onset of symptoms and arrival at hospital. INTERPRETATION: Age is an important independent predictor of in-hospital mortality and lower thrombolytic use following AMI. Other studies are required to further evaluate the appropriateness of thrombolytic therapy for elderly patients.

Predictors of persistence of use of the novel antidiabetic agent acarbose.

BACKGROUND: A carbose is the first of a new class of antidiabetic agents, the alpha-glucosidase inhibitors. This study characterizes and identifies predictors of persistence of use of acarbose. METHODS: Medical, pharmaceutical, and demographic records were extracted for 2 cohorts of patients (social assistance recipients and seniors) from the databases of Quebec's provincial health plan. Patients were eligible for inclusion if they had received their first dispensation of acarbose between August 1, 1996, and December 31, 1997. The observation period included at least 1 year before the first dispensation and a minimum of 4 months after. RESULTS: New users of acarbose included 216 social assistance recipients and 677 seniors who were followed up for 82 914 and 270 041 person-days, respectively. Median persistence with acarbose treatment was 83 days (95% confidence interval, 75-105 days) for social assistance recipients and 105 days (95% confidence interval, 90-119 days) for seniors. In both cohorts, treatment by an endocrinologist vs another physician predicted longer treatment persistence. In the seniors cohort, additional determinants of (earlier) treatment discontinuation included a higher initial daily dose, previous treatment with insulin, and consultation with a gastroenterologist after treatment initiation. CONCLUSIONS: New users of acarbose showed low persistence in 2 cohorts of beneficiaries of Quebec's provincial health plan. Prescribing specialist was an important predictor of persistence in seniors and the socially assisted. The importance of 4 additional factors in seniors only led to hypotheses concerning population differences in treatment expectations and in the occurrence and tolerance of adverse effects.

Estrogen replacement therapy: determinants of persistence with treatment.

OBJECTIVE: To evaluate the persistence rate for estrogen therapy and to identify its determinants. METHODS: From the Quebec health insurance database we chose a cohort of 4527 women 35 years and older who received social assistance and were new users of estrogen between January 1989 and December 1997. Incident use was defined by the absence of any dispensed prescription of estrogen in the 3 years before the index date (date of first dispensed prescription). We estimated the cumulative persistence rate of treatment by Kaplan-Meier failure time analysis and identified its determinants with the Cox proportional hazards model. RESULTS: From the initial cohort, 3395 women (75%) renewed their first dispensed prescription and 905 (20%) continued treatment after 4 years. The determinants measured at the index date and significantly associated with a better persistence rate (relative risk [RR]) were younger than 60 years (RR 1.15, 95% confidence interval [CI] 1.01, 1.30), low dosage (RR 1.49, 95% CI 1.32, 1.70), continuous progestin combination (RR 1.40, 95% CI 1.27, 1.54), and a gynecologist as the first prescribing physician (RR 1.15, 95% CI 1.03, 1.21). Also, coronary heart disease or at least one risk factor for it in the year before the index date was associated with a better persistence rate for estrogen replacement therapy (RR 1.15, 95% CI 1.05, 1.22). CONCLUSIONS: The persistence rate for estrogen therapy is poor, implying that few women take it long enough to benefit from it.

Cost of prescribed NSAID-related gastrointestinal adverse events in elderly patients.

AIMS: It is well established that nonsteroidal anti-inflammatory drugs (NSAIDs) have gastrointestinal (GI) side-effects. However, the cost of health care resources spent on preventing and managing these side-effects is not clear. The objective of this study was to estimate the direct cost of NSAID-related GI events in an elderly population. METHODS: From the Régie de l'assurance-maladie du Québec (RAMQ) database, we obtained medical, pharmaceutical and demographic records of a 10% random sample (n = 49 033) of seniors who, between January 1, 1993 and December 31, 1997, had a dispensed prescription of a NSAID. Patients who did not have any GI events during the year prior to their first dispensed prescription were included in the cohort. All patients were followed-up for 2 years. The daily direct Canadian dollar costs of GI events that were incurred by these patients while they were on NSAID therapy were compared with those of GI events that were incurred by these same patients while they were not on NSAID therapy. The difference in these daily costs was attributed to NSAIDs. RESULTS: A total of 12 082 new NSAID users were included in the study. Two hundred and seventeen (1.8%) were hospitalized for GI-related problems; of these, 130 (60%) had their GI hospitalization as their first GI event; 3257 (27.0%) used gastroprotective agents (GPAs), and 857 (26.3%) took GPAs without any apparent prior GI symptoms; 801 (6.6%) had GI diagnostic tests; and 661 (5.5%) died. The average direct costs of GI side-effects per patient-day on NSAIDs were 3.5 times higher than those of a patient-day not on NSAIDs. The direct cost of GI side-effects per patient-day on NSAIDs was $1.34, of which more than 70% ($0.94) was attributed to GI events resulting from NSAID treatment. CONCLUSIONS: Approximately one Canadian dollar was added to patient costs for every day he/she was on NSAID therapy. Safer therapies and appropriate patient risk management may potentially reduce NSAID-related health care resource use.

Impact of a cost-sharing drug insurance plan on drug utilization among older people.

OBJECTIVES: In August 1996, the Régie de l'assurance-maladie du QuEbec (RAMQ), the government body responsible for medical insurance in the Canadian province of Quebec, introduced a cost-sharing drug insurance plan. Before this plan, individuals age 65 years and older had to pay Canadian (CDN)$2 per prescription, with the remaining cost paid by the RAMQ. With the new plan, beneficiaries may have to pay an amount between CDN$200 and CDN$925 per year, depending on their income. Concerned that this financial constraint imposed on older people might have an impact on the use of medications, we investigated whether the consumption of four classes of medications, antihypertensive agents, anticoagulants, nitrates, and benzodiazepines, was affected by the drug plan implementation. DESIGN: Time series models with pre/post comparison group. SETTING: Administrative computerized databases of the RAMQ. PARTICIPANTS: Random sample of Quebec residents age 65 years and older registered in the provincial drug plan between August 1992 and June 1997: 54,771 users of nitrates, 133,146 users of antihypertensive agents, 45,534 users of anti-coagulants, and 26,165 users of benzodiazepines. MEASUREMENTS: We modeled the monthly consumption of the medications under study between August 1992 and June 1996. Monthly drug consumptions predicted from the models were compared with those observed for the 13 months (August 1996 to August 1997) following the implementation of the new drug plan using 95% confidence intervals. The number of prescriptions dispensed served as an indicator for drug consumption. RESULTS: During the study period we observed a nonstatistically significant decrease in number of prescriptions of 5.1% for nitrates, 1.1% for antihypertensive agents, and 0.8% for benzodiazepines, and a nonstatistically significant increase of 1.6% for anticoagulants. CONCLUSION: Residents of Quebec age 65 years and older were not found to have reduced significantly their consumption of nitrates, antihypertensive agents, anticoagulants, and benzodiazepines during the 13 months that followed the implementation of a cost-sharing drug insurance plan.

Gastrointestinal-related healthcare resource usage associated with a fixed combination of diclofenac and misoprostol versus other NSAIDs.

OBJECTIVE: To compare gastrointestinal (GI) healthcare resource use (HCRU) and associated costs in patients taking a fixed combination of diclofenac and misoprostol versus other nonsteroidal anti-inflammatory drugs (NSAIDs). METHODS: We analysed a sample (49,033 patients) of the Government of Quebec Health Insurance Agency database. Patients were included in the study if they did not have GI events during the year preceding the date of their first NSAID prescription dispensing (the index date). Patients were followed up for 2 years. A 3-stage model was used to determine the factors that influenced the direct medical costs of GI HCRU: (i) a logistic regression model (model 1) to estimate the risk of GI HCRU; (ii) a linear regression model (model 2) to estimate the direct costs of GI HCRU for those who had such events; (iii) multiplying the estimated risks from model 1 by the estimated costs from model 2 gave the estimated direct costs of GI HCRU for all patients. STUDY PERSPECTIVE: Provincial government of Quebec, Canada. RESULTS: 1,533 patients were prescribed diclofenac/misoprostol at the index date and 10,540 another NSAID. Comorbidity markers were not significantly different between the 2 groups. Of the diclofenac/misoprostol patients, 23 (1.5%) were hospitalised for GI problems compared with 194 (1.8%) of the NSAID group; 403 (26.3%) of diclofenac/misoprostol patients used gastroprotective agents compared with 2,849 (27.0%) of the NSAID patients; 118 (7.7%) of diclofenac/misoprostol patients had GI diagnostic tests compared with 682 (6.5%) of the NSAID patients. The average direct medical cost of GI HCRU was 310.52 Canadian dollars ($Can)/patient (1997 values) in the diclofenac/misoprostol group compared with $Can231.19/patient (1997 values) in the NSAID group. When adjusted for baseline factors, the ratio of the total direct medical cost of GI HCRU in the diclofenac/misoprostol group to that of the NSAID group was 1.15 (95% confidence interval: 0.89, 1.48). CONCLUSIONS: Our data showed no significant differences in GI HCRU among patients taking diclofenac/misoprostol compared with those taking NSAIDs.

Association between the burden of disease and research funding by the Medical Research Council of Canada and the National Institutes of Health. A cross-sectional study.

BACKGROUND: The Medical Research Council of Canada (MRCC) is the major Canadian agency responsible for funding biomedical health research in this country. Disease-specific funding by the United States National Institutes of Health (NIH) has been studied and is not independent of burden-of-disease parameters. We tested the association between disease-specific MRCC funding, disease-specific NIH funding and various burden-of-disease parameters. METHOD: Information on 1994/99 MRCC funding was obtained from the MRCC database for 29 diseases. NIH funding and burden-of-disease counterparts for the year 1996 were gleaned from a recent publication. The association between data series was measured by correlation coefficients. RESULTS: Disease-specific incidence, mortality and years-of-life lost did not correlate significantly with 1994/99 disease-specific MRCC funding but prevalence (r = 0.54, p = 0.005) and disability-adjusted life-years did (r = 0.48, p = 0.009). A correlation coefficient of 0.50 (p = 0.006) was calculated between 1996 NIH funding and 1996/97 MRCC funding. Two disease categories, cirrhosis and alcohol abuse, received a greater percentage of funds from the NIH than from the MRCC. Two other disease categories, epilepsy and perinatal disease, received a greater percentage of funds from the MRCC than from the NIH. CONCLUSIONS: Disease-specific MRCC grants in the past 5 years correlated with 2 of the usual burden-of-disease parameters: disability-adjusted life-years and disease prevalence. A statistically-significant correlation was observed between disease-specific grants awarded by the MRCC and the NIH.

The science of health technology assessment--clinical effectiveness of therapeutic interventions.

Important information is not, and cannot, be available at the time a new drug enters the market. Delaying registration is not the answer because most of this information can only be obtained in a real life situation. Several types of postmarketing (phase IV studies) can be identified. The active pharmacovigilance cohort who allows large number of patients to be followed for long periods of time can answer questions about the incidence of rare events (less than one of 3000 patients). The prospective effectiveness cohort can answer questions on long term efficacy (more than two years). The simplified clinical trial, which implies randomly assigning patients and then following them with a 'naturalistic' protocol can answer questions about effectiveness (efficacy in real life). The drug use study is the only way to answer questions of key importance to drug plan managers such as 'which drug(s) is it going to replace?' and 'is it going to be used as first line or second line?'. Phase IV studies, which in some cases should be mandatory (conditional registration), are essential for the protection of the patients and the proper use of public funds to reimburse drugs.

Gastrointestinal health care resource use and costs associated with nonsteroidal antiinflammatory drugs versus acetaminophen: retrospective cohort study of an elderly population.

OBJECTIVE: To estimate gastrointestinal (GI) health care resource use and direct costs associated with prescription nonsteroidal antiinflammatory drugs (NSAIDs) in an elderly population. METHODS: Using the Government of Quebec's health insurance database, we obtained the medical, pharmaceutical, and demographic records of 73,850 senior citizens who, between 1993 and 1997, had either an NSAID or an acetaminophen prescription dispensed. The date of their first dispensed prescription for an NSAID or acetaminophen was termed their index date. Patients who were not taking oral corticosteroids or anticoagulants at their index date, were not diagnosed with cancer at their index date, and were not hospitalized and did not have any GI events during the year prior to their index date were included in the study. Patients who had a dispensed NSAID prescription at their index date formed the NSAID cohort; the others formed the acetaminophen cohort. All patients were followed up for 2 years. The daily direct costs of GI events incurred during NSAID therapy by the NSAID cohort were compared with those incurred during a similar followup period by the acetaminophen cohort. The difference in these average daily costs was attributed to NSAID use. RESULTS: The NSAID cohort included 5,268 senior citizens and the acetaminophen cohort 2,245. More GI adverse events were observed in the NSAID cohort (odds ratio 2.48, 95% confidence interval 2.06, 3.00). The average daily direct cost of GI events for a day of NSAID therapy attributed to the NSAIDs was $0.84 (Canadian). On average, for each Canadian dollar spent on NSAIDs, an additional $0.66 was spent on their side effects. CONCLUSION: Safer alternatives to NSAIDs would significantly reduce medical care costs for patients in need of NSAID therapy.

Savings in direct medical costs from the use of tobramycin solution for inhalation in patients with cystic fibrosis.

OBJECTIVE: Two identical 24-week, double-blind, placebo-controlled trials of tobramycin solution for inhalation (TOBI [PathoGenesis Corporation, Seattle, Washington]) in cystic fibrosis patients with chronic Pseudomonas aeruginosa infection were conducted in the United States. The aim of the present study was to extrapolate the US trial data to a Canadian setting, using Canadian costs to estimate the savings in direct medical costs that might result from use of a similar 24-week TOBI regimen versus usual care in 2 Canadian provinces. BACKGROUND: Cystic fibrosis is a genetic disease in which persistent respiratory infection, usually due to P. aeruginosa infection, is the major cause of morbidity and mortality. METHODS: The US trials demonstrated that TOBI produced significant improvements in pulmonary function test results, reduced sputum levels of P. aeruginosa, and resulted in a 26% reduction in the probability of hospitalization (95% CI, 2%-43% vs placebo in the clinical trials). Individual patient data from the US trials were used to calculate the mean number of days in hospital as well as the mean number of days of home intravenous or oral antibiotic therapy. To adjust for Canadian pricing, pertinent economic data were obtained from Statistics Canada and the Ontario and Quebec health ministries. Demographic and baseline data were obtained from health surveys conducted by the Canadian Cystic Fibrosis Foundation. RESULTS: Economic analysis showed that the use of TOBI for 24 weeks would result in estimated mean per-patient savings in direct medical costs (in Canadian dollars) of $4055 in Ontario and $4916 in Quebec, which would substantially offset the Canadian acquisition price of $8602 for the same 24-week period. CONCLUSIONS: Assuming that the percentage of reduction in hospital days observed in the US trials would also occur in the Canadian clinical setting, use of TOBI would reduce the use of health care services, particularly hospital days, and lead to substantial savings in direct medical costs that would offset its acquisition price. Whether this reduction actually occurs after TOBI enters the Canadian market is a subject for future investigation.

Patterns of amlodipine and felodipine use in an elderly Quebec population.

OBJECTIVES: To assess drug prescription patterns and medical resource consumption in an elderly population in Quebec receiving amlodipine or felodipine for the treatment of hypertension. PATIENTS AND METHODS: Sociodemographic, clinical and drug claim data for a random sample of hypertensive patients 65 years of age and older with at least one claim for amlodipine or felodipine between August 1, 1990 and August 31, 1997 were extracted from the Régie de l'assurance maladie du Québec (RAMQ) database. Patterns of prescription renewal, drug switch and compliance rates, and health care resource use were established for both an amlodipine and a felodipine group. Long term persistence on treatment was quantified by survival curve analysis. RESULTS: The amlodipine (5188 patients) and felodipine (2630 patients) groups were similar in terms of sex ratio (66.7% female) and age (mean 74 years). Average compliance rates for amlodipine patients (67.9%) were significantly higher than for felodipine patients (66.2%) (P<0.01), and switch rates were 5.4-fold higher in the latter group. Patients initiating treatment with felodipine had a 27% increased rate of discontinuation (relative risk 1.27) compared with the amlodipine patients. In addition, patients with at least one year of follow-up data were more likely to maintain amlodipine as part of their antihypertensive regimens than felodipine. After adjustment, medical resource consumption patterns were similar for both groups except for an increase in the number of specialist visits for the amlodipine treatment group. CONCLUSIONS: Patients who received amlodipine, either as a monotherapy or as part of a multitherapy regimen, were more compliant and persistent with their treatment than patients on felodipine. The data suggest that amlodipine may provide more effective long term hypertension control than felodipine, and that the two drugs are not therapeutically equivalent.

Using healthcare claims data for outcomes research and pharmacoeconomic analyses.

Healthcare claims data are a practical complement to data from randomised controlled trials (RCTs) for evaluating health outcomes in non-experimental settings and for generalising results to a broader population. Claims data are a relatively inexpensive way to obtain useful information about patient demographics, as well as healthcare resources used for specific medical conditions and procedures from large numbers of patients over extended periods of time. With claims data, it is possible to identify patients who meet specific medical or sociodemographic criteria, estimate their costs, define episodes of medical care, and measure outcomes more globally than is possible with RCT data. Statistical methods exist to address some of the inherent issues with claims data due to their limited clinical detail. We also identify extensions of claims data to productivity issues, the use of centralised claims data such as in Canada, and the application of new statistical methods to outcomes research literature such as sample selection correction methods.

Pharmacoeconomics and health policy. Current applications and prospects for the future.

The use of pharmacoeconomic tools has grown dramatically in the past decade as provision of healthcare throughout the industrialised world has required increased cost consciousness. However, pharmacoeconomic analysis has not yet been fully exploited as a conceptual underpinning for public or private health policy decisions. Pharmacoeconomics is likely to become an increasingly important basis for health policy decisions as a number of significant dynamics evolve in the marketplace, including: (i) consumers acting on their growing access to information and becoming more actively involved in treatment decisions; (ii) payers, providers and patients deepening their interaction and overcoming their traditional (narrow) focus on either costs or benefits alone; and (iii) manufacturers being challenged by other healthcare constituencies as sponsors of cost-based outcomes studies.

Association of inhaled corticosteroid use with cataract extraction in elderly patients.

CONTEXT: The use of systemic corticosteroids is a known risk factor for the development of cataracts. OBJECTIVE: To determine whether treatment with inhaled corticosteroids is associated with cataract extraction in the elderly. DESIGN: Case-control study. SETTING: Quebec universal health insurance program for all elderly (provincial health insurance plan database [RAMQ database]). PATIENTS: RAMQ enrollees 70 years and older. The 3677 cases were patients with a cataract extraction between 1992 and 1994. The 21868 controls were randomly selected from patients who did not have a diagnosis of cataract and matched to cases on the index date of the case. MAIN OUTCOME MEASURES: Odds ratio of cataract extraction in patients with prolonged cumulative exposure to inhaled corticosteroids compared with nonusers. RESULTS: Excluding patients with systemic steroid treatment and after adjusting for age, sex, diabetes, systemic hypertension, glaucoma, ophthalmic steroids, and the number of physician claims for services, use of inhaled corticosteroids for more than 3 years was associated with undergoing cataract extraction (odds ratio [OR], 3.06; 95% confidence interval [CI], 1.53-6.13). For high average daily doses of beclomethasone or budesonide (>1 mg), the OR was elevated after more than 2 years of treatment (OR, 3.40; 95% CI, 1.49-7.76), whereas for low to medium doses (< or =1 mg) of these drugs, the OR was 1.63 (95% CI, 0.85-3.13) after 2 years. CONCLUSION: Prolonged administration of high doses of inhaled corticosteroids increases the likelihood of undergoing cataract extraction in elderly patients. Further studies are needed to investigate the risk of developing cataracts for low to medium doses over longer periods.
