Proton-Pump Inhibitors and Long-Term Risk of Community-Acquired Pneumonia in Older Adults.

ABSTRACT:

Objectives

To estimate associations between long-term use of proton pump inhibitors (PPIs) and pneumonia incidence in older adults in primary care.

Design

Longitudinal analyses of electronic medical records.

Setting

England PARTICIPANTS: Individuals aged 60 and older in primary care receiving PPIs for 1 year or longer (N=75,050) and age- and sex-matched controls (N=75,050).

Measurements

Net hazard ratios for pneumonia incidence in Year 2 of treatment were estimated using the prior event rate ratio (PERR), which adjusts for pneumonia incidence differences before initiation of treatment. Inverse probability weighted models adjusted for 78 demographic, disease, medication, and healthcare usage measures.

Results

During the second year after initiating treatment, PPIs were associated with greater hazard of incident pneumonia (PERR-adjusted hazard ratio=1.82, 95% confidence interval=1.27-2.54), accounting for pretreatment pneumonia rates. Estimates were similar across age and comorbidity subgroups. Similar results were also obtained from propensity score- and inverse probability-weighted models.

Conclusion

In a large cohort of older adults in primary care, PPI prescription was associated with greater risk of pneumonia in the second year of treatment. Results were robust across alternative analysis approaches. Controversies about the validity of reported short-term harms of PPIs should not divert attention from potential long-term effects of PPI prescriptions on older adults.

Project description:BackgroundUse of proton pump inhibitors (PPIs) is associated with community-acquired pneumonia (CAP), an association which may be confounded by unobserved patient and prescriber characteristics.ObjectiveWe assessed for confounding in the association between PPI use and CAP by using a 'falsification approach,' which estimated whether PPI use is also implausibly associated with other common medical conditions for which no known pathophysiologic link exists.DesignRetrospective claims-based cohort study.SettingSix private U.S. health plans.SubjectsIndividuals who filled at least one prescription for a PPI (N = 26,436) and those who never did (N = 28,054) over 11 years.InterventionsMultivariate linear regression of the association between a filled prescription for a PPI and a diagnosis of CAP in each 3-month quarter. In falsification analyses, we tested for implausible associations between PPI use in each quarter and rates of osteoarthritis, chest pain, urinary tract infection (UTI), deep venous thrombosis (DVT), skin infection, and rheumatoid arthritis. Independent variables included an indicator for whether a prescription for a PPI was filled in a given quarter, and quarterly indicators for various co-morbidities, age, income, geographic location, and marital status.Key resultsCompared to nonusers, those ever using a PPI had higher adjusted rates of CAP in quarters in which no prescription was filled (68 vs. 61 cases per 10,000 persons, p < 0.001). Similar associations were noted for all conditions (e.g. chest pain, 336 vs. 282 cases, p < 0.001; UTI, 151 vs. 139 cases, p < 0.001). Among those ever using a PPI, quarters in which a prescription was filled were associated with higher adjusted rates of CAP (111 vs. 68 cases per 10,000, p < 0.001) and all other conditions (e.g. chest pain, 597 vs. 336 cases, p < 0.001; UTI, 186 vs. 151 cases, p < 0.001), compared to quarters in which no prescription was filled.ConclusionPPI use is associated with CAP, but also implausibly associated with common medical conditions. Observed associations between PPI use and CAP may be confounded.

Project description:Introduction: Prescribing cascade refers to use of a medication to treat a drug-related adverse event. Prescribing cascades increase medication use, cost, and risk of adverse events. Objective: Our objective was to use administrative health data to identify whether use of medications from the anticholinergic cognitive burden scale was associated with proton pump inhibitor (PPI) prescribing consistent with a prescribing cascade in older adults with dementia. Method: The cohort was comprised of Nova Scotia Seniors' Pharmacare beneficiaries identified to have dementia and medication dispensation data recorded between 1 April 2010, or cohort entry and 31 March 2015. Anticholinergic medications from the anticholinergic cognitive burden scale (ACB) were abstracted. A look back period of 365 days identified if a PPI had been dispensed preceding anticholinergic dispensation. PPI initiation within 30, 60, 90, or 180 days of the anticholinergic medication was assessed. Demographic description of those dispensed anticholinergic medications or PPIs were reported. Risk factors for the prescribing cascade were investigated with logistic regression and Cox proportional hazards modelling including a sex-stratified analysis. Results: We identified 28,952 Nova Scotia Seniors' Pharmacare beneficiaries with dementia and prescription dispensation data. Anticholinergic medications were frequently dispensed with 63.4% of the cohort dispensed at least one prescription for an anticholinergic medication. The prescribing cascade defined as up to 180-days between anticholinergic medication inititation and PPI dispensation, occurred in 1,845 Nova Scotia Seniors' Pharmacare beneficiaries with dementia (incidence 6.4%). Multivariate regression showed those experiencing the prescribing cascade after initiating any anticholinergic were younger (OR 0.98, 95%CI [0.97-0.98]), less likely to live in an urban location (OR 0.82, 95%CI [0.74-0.91]), or to be men (OR 0.74, 95%CI [0.67-0.82]). Cox regression demonstrated an increased risk of starting a PPI within 180 days when initiating any medication from the ACB (HR 1.38, 95%CI [1.29-1.58]). Discussion: Regression modelling suggested that anticholinergic medications increased the risk of PPI dispensation consistent with a prescribing cascade in the cohort. The identification of the prescribing cascade in this population of older Nova Scotia Seniors' Pharmacare Program beneficiaries with dementia using administrative health data highlights how routinely collected health data can be used to identify prescribing cascades.
