RESUMEN

OBJECTIVE: We studied whether the use of hydroxychloroquine (HCQ) for COVID-19 resulted in supply shortages for patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). METHODS: We used US claims data (IQVIA PHARMETRICS® Plus for Academics [PHARMETRICS]) and hospital electronic records from Spain (Institut Municipal d'Assistència Sanitària Information System [IMASIS]) to estimate monthly rates of HCQ use between January 2019 and March 2022, in the general population and in patients with RA and SLE. Methotrexate (MTX) use was estimated as a control. RESULTS: More than 13.5 million individuals (13,311,811 PHARMETRICS, 207,646 IMASIS) were included in the general population cohort. RA and SLE cohorts enrolled 135,259 and 39,295 patients, respectively, in PHARMETRICS. Incidence of MTX and HCQ were stable before March 2020. On March 2020, the incidence of HCQ increased by 9- and 67-fold in PHARMETRICS and IMASIS, respectively, and decreased in May 2020. Usage rates of HCQ went back to prepandemic trends in Spain but remained high in the United States, mimicking waves of COVID-19. No significant changes in HCQ use were noted among patients with RA and SLE. MTX use rates decreased during HCQ approval period for COVID-19 treatment. CONCLUSION: Use of HCQ increased dramatically in the general population in both Spain and the United States during March and April 2020. Whereas Spain returned to prepandemic rates after the first wave, use of HCQ remained high and followed waves of COVID-19 in the United States. However, we found no evidence of general shortages in the use of HCQ for both RA and SLE in the United States.

RESUMEN

Although drugs for osteoporosis have been demonstrated to be effective in reducing fracture risk in placebo-controlled clinical trials, data on effectiveness in real-world practice is limited. Data from the French national health insurance claims database (SNDS) were used to follow five cohorts of women aged ≥55 years after initiating treatment for ≥6 months with either denosumab, zoledronic acid, oral bisphosphonates, raloxifene, or teriparatide in 2014-2016. Fracture incidence was compared within each cohort between the 3 months following initiation (baseline fracture risk) and the 12month, 18month, and 24 month postinitiation periods. Data are presented as incidence rate ratios (IRRs) with their 95% confidence intervals (CIs)s. Overall, 67,046 women were included in the denosumab cohort, 52,914 in the oral bisphosphonate cohort, 41,700 in the zoledronic acid cohort, 11,600 in the raloxifene cohort, and 7510 in the teriparatide cohort. The baseline vertebral fracture rate ranged from 1.74 per 1000 person years (‰PY) in the raloxifene cohort to 34.75‰PY in the teriparatide cohort, and the baseline hip fracture rate from 0.70‰PY in the raloxifene cohort to 10.52‰PY in the zoledronic acid cohort. Compared with the baseline fracture rate, vertebral fractures involving hospitalization were significantly reduced in the 3-24-month postinitiation period with denosumab (IRR 0.6; 95% CI, 0.5-0.7), zoledronic acid (IRR 0.4; 95% CI, 0.3-0.4), teriparatide (IRR 0.3; 95% CI, 0.2-0.5), and oral bisphosphonates (IRR 0.6; 95% CI, 0.4-0.8). Hip fracture incidence was reduced with denosumab (IRR 0.8; 95% CI, 0.6-0.9), but higher for oral bisphosphonates (IRR 1.7; 95% CI, 1.2-2.3); no significant change in hip fracture rate was observed for zoledronic acid, teriparatide, or raloxifene. A reduction in nonvertebral, non-hip fracture incidence was observed only in the denosumab cohort (IRR 0.8; 95% CI, 0.7-0.9). These findings indicate that treatment with osteoporosis drugs is effective in the real-world setting. © 2023 The Authors.

RESUMEN

PURPOSE: The objective was to compare the risk of malignancies in real-world settings between exclusive immunosuppressant (IS) and immunomodulator (IM) use in multiple sclerosis (MS). METHODS: A nested case-control study was designed within a new-user cohort of all patients with MS who initiated a first IM or IS between 2008 and 2014, and without cancer history, using the information of the SNDS nationwide French claims database. Incident cancer cases were matched with up to six controls on year of birth, sex, initiation date, and disease risk score of cancer. A conditional logistic regression (odds ratio [95% confidence interval]) was used to compare exclusive IS versus IM use during follow-up and according to three use durations. RESULTS: From 28 720 newly treated patients with MS, 407 incident cancers were observed during the follow-up with 2324 matched controls. A significant increase in cancer risk was observed for IS compared with IM (1.36 [1.05, 1.77]), with similar increases for the first 2 years of use but not for ≥2 years (1.06 [0.65, 1.75]). Similar increase was also observed for IS with indications other than MS (1.37 [1.04, 1.81]) but not for IS indicated only in MS (1.03 [0.45, 2.34]). CONCLUSIONS: Compared with IM, a 37% increase in cancer risk was observed for IS with indications other than MS and used for a short duration (≤2 years) but not for IS indicated only in MS. The absence of risk for prolonged exposure of IS with indications other than MS is not in favor of a causal relation with these drugs.

RESUMEN

We studied the characteristics of patients prescribed osteoporosis medication and patterns of use in European databases. Patients were mostly female, older, had hypertension. There was suboptimal persistence particularly for oral medications. Our findings would be useful to healthcare providers to focus their resources on improving persistence to specific osteoporosis treatments. PURPOSE: To characterise the patients prescribed osteoporosis therapy and describe the drug utilization patterns. METHODS: We investigated the treatment patterns of bisphosphonates, denosumab, teriparatide, and selective estrogen receptor modulators (SERMs) in seven European databases in the United Kingdom, Italy, the Netherlands, Denmark, Spain, and Germany. In this cohort study, we included adults aged ≥ 18 years, with ≥ 1 year of registration in the respective databases, who were new users of the osteoporosis medications. The study period was between 01 January 2018 to 31 January 2022. RESULTS: Overall, patients were most commonly initiated on alendronate. Persistence decreased over time across all medications and databases, ranging from 52-73% at 6 months to 29-53% at 12 months for alendronate. For other oral bisphosphonates, the proportion of persistent users was 50-66% at 6 months and decreased to 30-44% at 12 months. For SERMs, the proportion of persistent users at 6 months was 40-73% and decreased to 25-59% at 12 months. For parenteral treatment groups, the proportions of persistence with denosumab were 50-85% (6 month), 30-63% (12 month) and with teriparatide 40-75% (6 month) decreasing to 21-54% (12 month). Switching occurred most frequently in the alendronate group (2.8-5.8%) and in the teriparatide group (7.1-14%). Switching typically occurred in the first 6 months and decreased over time. Patients in the alendronate group most often switched to other oral or intravenous bisphosphonates and denosumab. CONCLUSION: Our results show suboptimal persistence to medications that varied across different databases and treatment switching was relatively rare.

RESUMEN

In this international study, we examined the incidence of hip fractures, postfracture treatment, and all-cause mortality following hip fractures, based on demographics, geography, and calendar year. We used patient-level healthcare data from 19 countries and regions to identify patients aged 50 years and older hospitalized with a hip fracture from 2005 to 2018. The age- and sex-standardized incidence rates of hip fractures, post-hip fracture treatment (defined as the proportion of patients receiving anti-osteoporosis medication with various mechanisms of action [bisphosphonates, denosumab, raloxifene, strontium ranelate, or teriparatide] following a hip fracture), and the all-cause mortality rates after hip fractures were estimated using a standardized protocol and common data model. The number of hip fractures in 2050 was projected based on trends in the incidence and estimated future population demographics. In total, 4,115,046 hip fractures were identified from 20 databases. The reported age- and sex-standardized incidence rates of hip fractures ranged from 95.1 (95% confidence interval [CI] 94.8-95.4) in Brazil to 315.9 (95% CI 314.0-317.7) in Denmark per 100,000 population. Incidence rates decreased over the study period in most countries; however, the estimated total annual number of hip fractures nearly doubled from 2018 to 2050. Within 1 year following a hip fracture, post-hip fracture treatment ranged from 11.5% (95% CI 11.1% to 11.9%) in Germany to 50.3% (95% CI 50.0% to 50.7%) in the United Kingdom, and all-cause mortality rates ranged from 14.4% (95% CI 14.0% to 14.8%) in Singapore to 28.3% (95% CI 28.0% to 28.6%) in the United Kingdom. Males had lower use of anti-osteoporosis medication than females, higher rates of all-cause mortality, and a larger increase in the projected number of hip fractures by 2050. Substantial variations exist in the global epidemiology of hip fractures and postfracture outcomes. Our findings inform possible actions to reduce the projected public health burden of osteoporotic fractures among the aging population. © 2023 The Authors.

RESUMEN

BACKGROUND AND OBJECTIVES: Some medications require specific medical procedures in the weeks before their start. Such procedures may meet the definition of instrumental variables (IVs). We examined how they may influence treatment effect estimation in propensity score (PS)-adjusted comparative studies, and how to remedy. STUDY DESIGN AND SETTING: Different covariate assessment periods (CAPs) did and did not include the month preceding treatment start were used to compute PS in the French claims database (Sytème National des Données de Santé-SNDS), and 1:1 match patients with metastatic castration resistant prostate cancer initiating abiraterone acetate or docetaxel. The 36-month survival was assessed. RESULTS: Among 1, 213 docetaxel and 2, 442 abiraterone initiators, the PS distribution resulting from the CAP [-12; 0 months] distinctly separated populations (c = 0.93; 273 matched pairs). The CAPs [-12;-1 months] identified 765 pairs (c = 0.81). Strong docetaxel treatment predictors during the month before treatment start were implantable delivery systems (1% vs. 59%), which fulfilled IV conditions. The 36-month survival was not meaningfully different under the [-12; 0 months] CAP but differed by 10% points (38% vs. 28%) after excluding month -1. CONCLUSION: In the setting of highly predictive pretreatment procedures, excluding the immediate pre-exposure time from the CAP will reduce the risk of including potential IVs in PS models and may reduce bias.

RESUMEN

BACKGROUND AND PURPOSE: Studies have not yet found conclusive results on the risk of cancer in patients with multiple sclerosis (MS). This study aimed to compare the incidence of all cancers and of specific types of cancer between MS patients and the general population by age and by sex. METHODS: All prevalent MS patients identified between 2008 and 2014 in the nationwide French health care database (Système National des Données de Santé) and without history of malignancy were included in a cohort study and followed up until cancer occurrence, date of death, or 31 December 2015, whichever came first. MS patients were matched based on sex and year of birth to non-MS controls from the general population without cancer before index date. Incidence rate was reported per 100,000 person-years (PY), and risk of cancer was estimated by type of cancer, age, and sex using a Cox model (hazard ratio [HR] and its 95% confidence interval [CI]). RESULTS: Overall, 576 cancers per 100,000 PY were observed in MS patients versus 424 per 100,000 PY in the control population. The risk of cancer was higher among MS patients than among population controls whether considered overall (HR = 1.36, 95% CI = 1.29-1.43) or for prostate (HR = 2.08, 95% CI = 1.68-2.58), colorectal and anal (HR = 1.35, 95% CI = 1.16-1.58), trachea, bronchus, and lung (HR = 2.36, 95% CI = 1.96-2.84), and to a lesser extent, breast cancer (HR = 1.12, 95% CI = 1.03-1.23). CONCLUSIONS: MS patients were associated with increased risk of cancer compared to population controls.

RESUMEN

AIMS: To assess the effectiveness of dimethyl fumarate (DMF) on annual rate of relapse subject to treatment (ARRt) and disability progression in multiple sclerosis (MS) compared to injectable immunomodulators (IMM), teriflunomide (TERI) and fingolimob (FTY), in real-life setting. METHODS: A population-based cohort study was conducted using data of the French nationwide claims database, SNDS. All patients initiating IMM, TERI, FTY or DMF between 1 July 2015 and 12 December 2017, with 4.5 years of database history and 1-3.5 years of follow-up were included in this study. DMF patients were 1:1 matched to IMM, TERI or FTY using a high dimensional propensity score. Negative binomial regression and a logistic regression model were used to estimate the relative risk (RR ± [95% CI]) of ARRt and the odds ratio (OR ± [95% CI]) of disability progression, respectively. RESULTS: Overall, 9304 subjects were identified: 29.0% initiated DMF, 33.2% TERI, 5.6% FTY and 32.2% an IMM. The matched cohorts consisted of 1779 DMF-IMM patients, 1679 DMF-TERI patients, and 376 DMF-FTY patients. DMF significantly reduced ARRt compared to IMM (RR 0.72 [0.61-0.86]) and TERI (0.81 [0.68-0.96]) and did not show any significant difference when compared with FTY. The risk of the progression of MS-specific disability was not significantly different for any matched cohorts. CONCLUSION: DMF is associated with lower risk of treated relapse for patients with RRMS than other first-line RRMS agents (TERI and IIM).

RESUMEN

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been discouraged for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, fearing that they could increase the risk of infection or the severity of SARS-CoV-2. METHODS: Original studies providing information on exposure to NSAIDs and coronavirus disease 2019 (COVID-19) outcomes were retrieved and were included in a descriptive analysis and a meta-analysis with Cochrane Revue Manager (REVMAN 5.4), using inverse variance odds ratio (OR) with random- or fixed-effects models. RESULTS: Of 92,853 papers mentioning COVID-19, 266 mentioned NSAIDs and 61 mentioned ibuprofen; 19 papers had analysable data. Three papers described NSAID exposure and the risk of SARS-CoV-2 positivity, five papers described the risk of hospital admission in positive patients, 10 papers described death, and six papers described severe composite outcomes. Five papers studied exposure to ibuprofen and death. Using random-effects models, there was no excess risk of SARS-CoV-2 positivity (OR 0.86, 95% confidence interval [CI] 0.71-1.05). In SARS-CoV-2-positive patients, exposure to NSAIDs was not associated with excess risk of hospital admission (OR 0.90, 95% CI 0.80-1.17), death (OR 0.88, 95% CI 0.80-0.98), or severe outcomes (OR 1.14, 95% CI 0.90-1.44). With ibuprofen, there was no increased risk of death (OR 0.94, 95% CI 0.78-1.13). Using a fixed-effect model did not modify the results, nor did the sensitivity analyses. CONCLUSION: The theoretical risks of NSAIDs or ibuprofen in SARS-CoV-2 infection are not confirmed by observational data.

RESUMEN

INTRODUCTION: Hip fractures are associated with a high burden of morbidity and mortality. Globally, there is wide variation in the incidence of hip fracture in people aged 50 years and older. Longitudinal and cross-geographical comparisons of health data can provide insights on aetiology, risk factors, and healthcare practices. However, systematic reviews of studies that use different methods and study periods do not permit direct comparison across geographical regions. Thus, the objective of this study is to investigate global secular trends in hip fracture incidence, mortality and use of postfracture pharmacological treatment across Asia, Oceania, North and South America, and Western and Northern Europe using a unified methodology applied to health records. METHODS AND ANALYSIS: This retrospective cohort study will use a common protocol and an analytical common data model approach to examine incidence of hip fracture across population-based databases in different geographical regions and healthcare settings. The study period will be from 2005 to 2018 subject to data availability in study sites. Patients aged 50 years and older and hospitalised due to hip fracture during the study period will be included. The primary outcome will be expressed as the annual incidence of hip fracture. Secondary outcomes will be the pharmacological treatment rate and mortality within 12 months following initial hip fracture by year. For the primary outcome, crude and standardised incidence of hip fracture will be reported. Linear regression will be used to test for time trends in the annual incidence. For secondary outcomes, the crude mortality and standardised mortality incidence will be reported. ETHICS AND DISSEMINATION: Each participating site will follow the relevant local ethics and regulatory frameworks for study approval. The results of the study will be submitted for peer-reviewed scientific publications and presented at scientific conferences.

RESUMEN

AIM: To describe the ambulatory changes in drug prescriptions 3 months after hospital discharge among elderly patients aged 75 and over, and to identify the reasons for these changes. METHODS: A prospective cohort study was conducted on subjects, discharged between 09/2016 and 01/2017 from the Bordeaux University Hospital. Prescription forms were collected from patients' pharmacists. The main outcome was the occurrence of at least one significant change (SC) defined as an initiation, a discontinuation, a switch or change in drug daily dosage as regards the drugs prescribed upon hospital discharge and those prescribed 3 months after. Whenever drug SC occurred, general practitioners were requested to elicit reasons for such changes. RESULTS: Among the 126 patients included in our study, 73 underwent a 3-month follow-up period, without death or being re-hospitalised. 87.7% of them had at least one SC 3 months after discharge, with an average of 3.1±2.5 SC per patient. Main changes involved: discontinuation or dose decrease of anxiolytics, hypnotics, antalgics, betablockers and calcium channel blockers; start or dose increase of diuretics, ACE inhibitors and angiotensin receptor blockers. In patients with a 3-month follow-up period, 27.4% underwent at least one ADR-induced SC. CONCLUSION: Most elderly patients experience drug prescription changes after discharge. Some, according to drug iatrogenic, could be avoided through better cooperation between hospital and ambulatory prescribers.

RESUMEN

BACKGROUND: Diagnosis performances of case-identifying algorithms developed in healthcare database are usually assessed by comparing identified cases with an external data source. When this is not feasible, intra-database validation can present an appropriate alternative. OBJECTIVES: To illustrate through two practical examples how to perform intra-database validations of case-identifying algorithms using reconstituted Electronic Health Records (rEHRs). METHODS: Patients with 1) multiple sclerosis (MS) relapses and 2) metastatic castration-resistant prostate cancer (mCRPC) were identified in the French nationwide healthcare database (SNDS) using two case-identifying algorithms. A validation study was then conducted to estimate diagnostic performances of these algorithms through the calculation of their positive predictive value (PPV) and negative predictive value (NPV). To that end, anonymized rEHRs were generated based on the overall information captured in the SNDS over time (e.g. procedure, hospital stays, drug dispensing, medical visits) for a random selection of patients identified as cases or non-cases according to the predefined algorithms. For each disease, an independent validation committee reviewed the rEHRs of 100 cases and 100 non-cases in order to adjudicate on the status of the selected patients (true case/ true non-case), blinded with respect to the result of the corresponding algorithm. RESULTS: Algorithm for relapses identification in MS showed a 95% PPV and 100% NPV. Algorithm for mCRPC identification showed a 97% PPV and 99% NPV. CONCLUSION: The use of rEHRs to conduct an intra-database validation appears to be a valuable tool to estimate the performances of a case-identifying algorithm and assess its validity, in the absence of alternative.

RESUMEN

OBJECTIVES: Tyrosine kinase inhibitors (TKIs) account for the vast majority of healthcare expenditure on patients with chronic myeloid leukemia (CML), and it has been demonstrated that TKI discontinuation in patients in long-term deep molecular remission (DMR) is safe and improves quality of life. Our objective was to estimate the budget impact of TKI discontinuation in CML patients in long-term DMR from the perspective of the French healthcare system. METHODS: This analysis was conducted over a 5-year time horizon using a Markov model with cycles of 6 months. Transition probabilities were estimated through systematic reviews and meta-analyses. Costs were estimated from the French National Claims Database. Monte Carlo simulations were performed to take into account the uncertainty surrounding model parameters. Sensitivity analyses were carried out by varying the size of the target population and the cost of TKIs. RESULTS: Over a 5-year period and for a target population of 100 patients each year eligible and agreeing to stop TKI, the TKI discontinuation strategy would save €25.5 million (95% confidence interval -39.3 to 70.0). In this model, the probability that TKI discontinuation would be more expensive than TKI continuation was 12.0%. In sensitivity analyses, mean savings ranged from €14.9 million to €62.9 million. CONCLUSIONS: This study provides transparent, reproducible, and interpretable results for healthcare professionals and policy makers. Our results clearly show that innovative healthcare strategies can benefit both the healthcare system and patients. Savings from generalizing TKI discontinuation in CML patients in sustained DMR should yield health gains for other patients.

RESUMEN

PURPOSE: To estimate annual incidence and prevalence of Treatment-Resistant Depression (TRD) in France. METHODS: We identified all adult patients (≥ 18 years) with a TRD episode between 1 January 2012 and 31 December 2014 in the EGB (Échantillon généraliste des bénéficiaires), a permanent random sample of the French nationwide claims database. After a 6-month washout period without hospitalization for depression or any antidepressants (AD), and after exclusion of psychotic or bipolar affective disorders, Parkinson's disease and dementia, a TRD episode was defined by three successive sequences of different AD over a 3-month treatment period (6 months for a sensitive analysis), with at least 3 weeks before each sequence change and a Medication Possession Ratio ≥ 80%; or by the dispensing of >two different AD together; or of an AD with a potentiator (lithium, antiepileptic drugs, antipsychotic drugs, thyroid hormones) over the same treatment period. The annual incidence rate was estimated from 2012 to 2014 and the prevalence using a Gamma parametric function based on treatment duration and a 30-year prediction. RESULTS: Between 2012 and 2014, 700 patients were identified in EGB with a TRD episode. The mean age was 47.4 years (±15.3); 52.7% were women. Annual incidence and prevalence of TRD were estimated at 5.8 and 25.8 per 10 000 patients, respectively and at 7.8 and 37.6 per 10 000 patients, respectively in the sensitivity analysis. CONCLUSION: This study provides the first population-based estimates for incidence and prevalence of TRD in France.

RESUMEN

BACKGROUND: Although the efficacy and safety of existing therapies of heart failure (HF) have been demonstrated in clinical trials, little is known about the treatment patterns in clinical practice, especially in France. OBJECTIVES: To describe the treatment initiation patterns and the subsequent treatment changes among HF patients, in the first year following an incident hospitalization for HF, in a French real-world setting. METHODS: A cohort of patients aged ≥ 40 years, with an incident hospitalization for HF between 01/01/2008 and 31/12/2013, was identified in the 1/97th permanent random sample of the French nationwide claims database and followed 1 year. HF drug exposure-beta blockers (BB), angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARBs), aldosterone antagonists (AA), diuretics, digoxin, or ivabradine-was assessed quarterly using a Proportion of Days Covered ≥ 66% (≥ 60 days out of the 90 days of the quarter), by considering HF drugs individually or in combination. Drug changes were assessed between each quarter. RESULTS: Between 2008 and 2013, 7387 patients were included. Their mean age was 77.7 years (± 12.0 years) and 51.6% were women. During the follow-up, 24.4% died, 20% were not exposed to any HF treatment, 48.3 to 43.2% had diuretics, one third had BB or ACEI, 9% had ARB or AA, 6% had digoxin, and 2% had ivabradine. The main change occurred between the first and the second quarter for 53.1% of the initially untreated patients. CONCLUSION: This study provides valuable information on treatment patterns after an initial hospitalization for HF.

RESUMEN

AIMS: In 2017, concerns regarding adverse events (AEs) associated with the Mirena levonorgestrel intrauterine device were largely echoed in the media in France. This resulted in a tremendous reporting of AEs to pharmacovigilance centres. The aim of this study was to describe the reporting of AEs regarding Mirena in France and to study the impact of media coverage on this reporting. METHODS: All cases reports involving Mirena recorded in the French national pharmacovigilance database from marketing (21 July 1995) until 04 August 2017 were extracted. To allow studying the influence of mediatisation, reports were described separately for the periods preceding and following the observed media coverage peak (15 May 2017). RESULTS: Overall, 3224 reports were considered, 510 (15.8%) recorded before the media coverage peak, and 2714 (84.2%) after. Before the peak, 76.5% of reports originated from health professionals; median time-to-report was of 5.5 months (interquartile range: 1.7-18.6), and median number of AEs per report was 1 (range: 1-17). After the peak, 98.6% originated from patients; median time-to-report was 21 months (interquartile range: 8.1-45.5), and median number of AEs per report was 6 (range: 1-37). After the peak, most reports mentioned anxio-depressive disorders (38.8 vs 10.6% before) or sexual disorders (47.3 vs 6.9%). Other emphasised AEs were weight increase (42.3 vs 10.2%) and pain (gastrointestinal, 19.1 vs 3.5%; musculoskeletal, 22.2 vs 4.5%). CONCLUSION: This study highlighted the importance of mediatisation impact on spontaneous reporting with changes concerning amounts of reports, type of reporter, and type of reported AEs. For Mirena, this led to generate signals regarding anxio-depressive and sexual disorders.

RESUMEN

OBJECTIVES: Metastatic colorectal cancer (mCRC) is increasingly treated with targeted therapies, but little is known about real-life mCRC treatment in older adults. The aims were to describe the real-life first-line treatment modalities in older adult mCRC patients, to identify factors associated with treatment modalities, and to evaluate survival with regard to treatment modalities. PATIENTS AND METHODS: A cohort of mCRC patients aged 65 years and older at diagnosis was identified between 2009 and 2013 using French national healthcare insurance system claims data. Treatment modalities were: treatment with one or more anticancer medication vs best supportive care and, among treated patients, treatment with targeted therapy vs conventional chemotherapy alone. Multivariate logistic regression was used to identify factors associated with treatment by anticancer medication and by targeted therapy. Cox proportional hazards models were used to assess the independent effect of treatment modalities on overall survival while adjusting for baseline covariates identified with logistic regression. RESULTS: A total of 503 patients were included with a median age of 78 years (54% were men). Of these, 299 (59%) were treated with anticancer medications. Among treated patients, 131 (44%) received targeted therapy. In multivariate analysis, age 75 years or older, renal failure, malnutrition, and five or more concomitant medications were associated with a lower likelihood of treatment with anticancer medications. Among treated patients, age 75 years or older, history of cancer, lymph node metastases, and a single metastatic site were associated with a lower likelihood of treatment with targeted therapy. Multivariate Cox proportional hazards models found that treatment with any anticancer medication tended to be associated with a lower risk of death; treatment with targeted therapy was not significantly associated. CONCLUSION: A more appropriate prescription of anticancer medications in the older adult will require the definition of more explicit criteria to avoid undertreatment. The real benefit of targeted therapies vs conventional chemotherapy alone needs to be confirmed in this population. J Am Geriatr Soc 67:913-919, 2019.

RESUMEN

OBJECTIVE: To compare the risk of all-cause death, hospitalizations (any cause), ectopic pregnancy, pelvic inflammatory disease or infection, uterine perforation, device removal, neuro-psychiatric drugs initiation, or new psychiatric visit(s) between levonorgestrel (LNG) 52 mg intrauterine system (IUS) and copper intrauterine device (IUD) users in France. STUDY DESIGN: We identified a historical cohort of women aged 20-55 years with a first dispensing of either LNG 52 mg IUS or copper-IUD between January 1, 2010, and December 31, 2014, in the French National Claims database, SNDS. We used propensity score matching to balance the two groups on baseline sociodemographic and clinical characteristics to minimize confounding. We estimated Cox proportional hazards models to compare health outcomes between LNG 52 mg IUS and copper-IUDs users. RESULTS: We matched 9318 LNG 52 mg IUS users (mean age 36.2±6.8 years) to 10,185 copper-IUD users (mean age 35.4±7.1 years). After matching and age-adjustment, LNG 52 mg IUS users had a slightly higher risk of anxiolytic drugs initiation (HR 1.08, 95%CI 1.01-1.15) and device removal (HR 1.05, 95%CI 1.01-1.10) compared to copper-IUD users, with no differences for other studied outcomes. CONCLUSION: French IUS users report slightly more anxiolytic treatment initiation and IUD removal compared to copper-IUD users. These results are consistent with a potential pharmacovigilance signal of anxiety-related disorders in LNG 52 mg IUS users. IMPLICATIONS STATEMENT: In French LNG 52 mg IUS users, there was slightly more anxiolytic treatment initiation and IUD removal compared to copper-IUD users. No risk difference was found for all-cause death, hospitalizations, ectopic pregnancy, pelvic disorders, and uterine perforation. We cannot exclude that the associations are related to differences in characteristics of women who chose each type of type of IUD.

RESUMEN

PURPOSE: Heart failure (HF) is a common, serious, and still poorly known illness, which might benefit from studies in claims databases. However, to provide reliable estimates, HF patients must be adequately identified. This validation study aimed to estimate the diagnostic accuracy of the International Classification of Diseases, Tenth Revision (ICD-10) codes I50.x, heart failure, in the French hospital discharge diagnoses database. METHODS: This study was performed in two university hospitals, comparing recorded discharge diagnoses and electronic health records (EHRs). Patients with discharge ICD-10 codes 150.x were randomly selected. Their EHRs were reviewed to classify HF diagnosis as definite, potential, or miscoded based on the European Society of Cardiology diagnostic criteria, from which the codes' positive predictive value (PPV) was computed. To estimate sensitivity, patients with an EHR HF diagnosis were identified, and the presence of the I50.x codes was sought for in the hospital discharge database. RESULTS: Two hundred possible cases of HF were selected from the hospital discharge database, and 229 patients with an HF diagnosis were identified from the EHR. The PPV of I50.x codes was 60.5% (95% CI, 53.7%-67.3%) for definite HF and 88.0% (95% CI, 83.5%-92.5%) for definite/potential HF. The sensitivity of I50.x codes was 64.2% (95% CI, 58.0%-70.4%). PPV results were similar in both hospitals; sensitivity depended on the source of EHR: Departments of cardiology had a higher sensitivity than had nonspecialized wards. CONCLUSIONS: Diagnosis codes I50.x in discharge summary databases accurately identify patients with HF but fail to capture some of them.
