Successful deprescribing of unnecessary proton pump inhibitors in a primary care clinic

Approaches to Deprescribing Proton Pump Inhibitors in Clinical Practice: A Systematic Review

Background: Proton pump inhibitors (PPIs) are some of the most frequently prescribed medications, but they are often used inappropriately, either being prescribed without a clear indication or continued for longer than necessary. In such cases, deprescribing is recommended. However, despite its proven effectiveness, the implementation of deprescribing in clinical practice remains inconsistent and varied, making it challenging to identify the most effective strategies. The goal is to provide a comprehensive outline of deprescribing interventions for PPI therapy implemented across various settings and by different healthcare professionals. Methods: The study is designed to be a systematic review of the published literature. PubMed, Embase, and Web of Science databases were searched from 1 January 1989 (the first PPI on the market) to 30 September 2024 for articles assessing PPI deprescribing in adult patients, focusing on the implementation rate (primary outcome) or effects on symptoms (secondary outcome). Results: After screening, 66 studies were included, predominantly pragmatic trials (N = 32) or randomized controlled trials (N = 25). We found a variety of interventions promoting PPI deprescription. Collaborative efforts involving multiple healthcare professionals, the use of algorithms for clinical decision-making, and patient involvement have proven to be key elements in the most effective strategies. Discontinuing therapy may not be advisable in cases of recurrent symptoms, suggesting that on-demand therapy could be a recommended approach. Deprescribing is particularly relevant for individuals with mild illnesses and symptoms, where tapering can effectively mitigate the rebound symptoms often associated with abrupt discontinuation. Conclusions: Given the current prevalence of inappropriate PPI prescribing, it is imperative to raise awareness among both physicians and patients about the importance of the deprescribing process, which should be tailored to the specific needs of each patient, considering his/her medical history, current health status, and personal preferences.

Appropriateness of proton pump inhibitor therapy in an ambulatory geriatrics clinic: A retrospective cross-sectional analysis

Background

Proton pump inhibitors are considered potentially inappropriate medications in the geriatric population. The use of proton pump inhibitors by older adults has increased over the past several decades; however, existing literature suggests that only one-third of patients prescribed these medications have a valid indication for use. The aim of this study was to assess the appropriateness of proton pump inhibitor therapy in a population of ambulatory geriatric patients and to determine the impact of an interdisciplinary clinic on their use.

Methods

This was a retrospective, cross-sectional study of patients referred to an ambulatory geriatrics clinic between October 2017 and March 2021. Participants were eligible for inclusion if they were taking a proton pump inhibitor at the time of clinic admission. Appropriateness of proton pump inhibitor therapy was assessed based on indication and dosing regimen.

Results

In total, 280 participants were included. The mean age was 79.6 years (SD 7.7) and 60% were female. Overall, 94 of 280 (33.6%) participants had a documented valid indication for their proton pump inhibitor. The clinic team intervened to reduce the dose or discontinue 76 of 186 (40.8%) inappropriate proton pump inhibitors.

Interpretation

Only one-third of proton pump inhibitors used by ambulatory geriatric patients have a documented appropriate indication for use. Given the medical complexity of this population and their vulnerability to adverse effects, the ambulatory geriatric population should be a priority target for proton pump inhibitor deprescribing initiatives.

Proton Pump Inhibitor Deprescription Prospective Study in Patients Without Indication: Are There Differences in Proportion of Restarts According to Withdrawal Strategy?

Background: The increasing utilization of proton pump inhibitors (PPIs) in patients without clear medical indications has raised concerns regarding potential risks, highlighting the importance of deprescription. However, comparative analyses of withdrawal strategies (abrupt vs gradual) in this context remain scarce or of low quality. Aim: This study aimed to evaluate the success rate of deprescribing PPIs in hospitalized patients without a documented indication and compare the proportion of treatment restarts based on withdrawal strategy. Method: An uncontrolled, open-label prospective observational study was conducted on patients receiving PPI treatment during hospital admission between May 2017 and July 2018. Deprescription was recommended for patients without a clear indication. Follow-up continued until discharge, with monitoring for rebound symptoms. The percentage of restarts based on the withdrawal strategy was compared using the chi-square test. Results: A total of 402 patients were reviewed, among whom 27% lacked a medical indication (mean age > 60 years, polymedicated), while 70% were prescribed PPIs electronically. Deprescription was performed in 49% of patients, with 64% undergoing abrupt withdrawal. Rebound symptoms led to treatment restart in 15% of cases. However, the chi-square test revealed no significant differences in restart proportions between the abrupt and gradual withdrawal groups (P = 0.365). Conclusion: Deprescribing PPIs is deemed safe, particularly for polymedicated geriatric patients, as it leads to a low percentage of restarts regardless of the chosen withdrawal strategy. However, the high percentage of PPI prescription without a clear indication underlines the need for periodic reassessment to avoid unnecessary risks and overuse.

Inappropriate proton-pump inhibitor prescribing in primary care - an observational study with quality circles

INTRODUCTION

Proton-pump inhibitors (PPIs) should be deprescribed when an indication is lacking or the dose is too high. Academic and media reports have tried to raise awareness and thereby reduce the inappropriate prescribing of PPIs. However, pharmacoepidemiologic studies have shown an unchanged frequency of such inappropriate prescribing over time. Little is known about whether or how general practitioners (GPs) adapt their prescribing practices once their awareness of inappropriate PPI prescribing has been raised.

OBJECTIVE

We aimed to investigate the prevalence of potentially inappropriate PPI prescribing (too high dose or no indication) in a consecutive sample of patients in Swiss primary care settings. Our goal was then to evaluate how GPs managed the patients with potentially inappropriate PPI prescribing over 12 months after flagging these patients.

METHODS

In this observational study, 11 GPs from the canton of Bern in Switzerland used their medical records to identify 20 patients who had been prescribed a PPI for ≥8 weeks and flagged potentially inappropriate PPI prescribing in their records. After 12 months, we asked the same GPs whether the PPI prescriptions of those patients had changed and, if so, how.

RESULTS

Of 1,376 patients consecutively screened, 206 (15%) had been prescribed a PPI for ≥8 weeks. Of these 206 patients, 85 (41%) had a potentially inappropriate PPI prescription. Of these 85 patients, 55 (65%) had no indication for PPI, and 30 (35%) had a too-high dose. After one year, only 29 (35%) of the 84 flagged potentially inappropriate PPIs were stopped or reduced. The most frequently mentioned reasons that deprescribing was not possible were a lack of discussion with the patient (no contact or no time), the presence of symptoms requiring the PPI, or the unwillingness of the patient to deprescribe.

CONCLUSION

In the Swiss primary care setting, the rate of potentially inappropriate PPI prescribing is high. Having GPs flag potentially inappropriate PPI prescribing did not result in PPI deprescribing in most patients over 12 months. Our findings suggest that more personalised and targeted interventions are necessary to successfully implement the deprescribing of potentially inappropriate PPIs. We see the need to co-design interventions with patients and providers and test behavioural change techniques to enable the deprescribing of inappropriate PPIs.

Outcomes of de-prescribing proton pump inhibitors during acute admissions in a general medical unit: a pilot study

The study describes the feasibility and short-to-medium-term efficacy of an evidence-based proton pump inhibitor (PPI) de-prescribing initiative undertaken as part of routine clinical care during acute admissions in a general medical unit. Of the 44 (median (IQR) age 75.5 (13.75) years; females 25 (57%)) who participated in the study, de-prescription was maintained in 29 (66%) and 27 (61%) patients at 12 and 26 weeks respectively.

Analysis of deprescription strategies of proton pump inhibitors in primary care: a narrative review

BACKGROUND

Since the introduction of omeprazole in 1989, proton pump inhibitors (PPIs) have become the mainstream of treatment for acid-related pathologies, but nowadays, it is estimated that between 20% and 80% of people worldwide who are using PPIs are doing so without an approved indication. Overusing PPIs is known to involve a tremendous cost in financial terms, and many western countries have reported high spending on these medicines.

OBJECTIVE

We conducted a narrative review to evaluate PPI deprescription strategies carried out entirely or in collaboration with primary care and to identify factors that could influence the success of these strategies.

METHOD

This review was conducted in November 2022, following PRISMA guidelines. Four databases were searched: PubMed, Web of Science, Scopus and CINAHL Complete, using the MeSH terms 'proton pump inhibitors' AND 'deprescriptions'.

RESULTS

The search with the established criteria found eight studies. The different success rates obtained by the various studies analysed in this review may be due to the different methodologies used when establishing the protocols, sample selection and monitoring of the results.

CONCLUSION

We can conclude that the two factors related to the most successful strategies were a) the clarity and simplicity of the de-escalation protocols, in which patients were instructed on the measures to follow in the event of the reappearance of symptoms, and b) the training of the physicians responsible for deprescribing. Long-term conclusions cannot be drawn about the effectiveness of these protocols, given that the studies are limited in time. Other barriers to generalizing the results are the small sample size and the absence of control groups.

Prescribing Patterns of Proton Pump Inhibitors in Germany: A Retrospective Study Including 472 146 Patients

The aims of this study were to analyze proton pump inhibitor (PPI) users in Germany, defining and classifying them in terms of treatment appropriateness, and to analyze the PPI prescription practices of healthcare providers. The updated DGVS (Deutsche Gesellschaft für Gastroenterologie, Verdauungs-und Stoffwechselkrankheiten) gastroesophageal reflux disease (GERD) treatment guideline (published March 2023) for mild heartburn symptoms recommends carrying out a probatory treatment of mild symptoms via other medication such as antacids, alginates, and H2 blockers before escalating to PPI treatments, if the patient profile allows. This retrospective cross-sectional study was based on data from the IQVIA™ Disease Analyzer database (DA) and included adult patients (18 years or older) in 1006 general and 39 gastroenterological practices in Germany who received at least 1 PPI prescription or alginate between September 2019 and September 2021 (hereinafter referred to as the index period). Analyses included indications associated with PPI prescription, co-diagnoses, co-therapies of PPI patients, duration of PPI therapy, dosages of PPI prescriptions, and proportions of practices prescribing PPIs and alginates. A total of 472 146 patients taking PPIs and 9101 patients taking alginates were available for analysis. Very few patients (4.5%) of the total cohort were treated in complete adherence to treatment guidelines. Conditions such as gastritis and duodenitis (47.2%) and reflux diseases (38.4%) were more frequently associated with PPI prescriptions. The average PPI treatment period lasted 141 days, and 36.6% of patients were treated for >6 months. High doses were prescribed relatively often (ie, 42.8% of esomeprazole prescriptions were 40 mg, 59.1% of lansoprazole prescriptions 30 mg, 28.6% of omeprazole prescriptions 40 mg). With each practice prescribing PPIs to at least 10% of their patients; 72% of general practitioners (GPs) and 8% of GENTS (Gastroenterologists) prescribed alginates. This study highlights that discrepancies exist between clinical guidelines and real-life prescribing practices of PPIs in Germany. Particular attention should be given to the incidence of patients being prescribed high-dose or long-duration PPI with mild indications. These findings are particularly apt considering the publication (March 2023) of new guidelines on the "management of gastroesophageal reflux disease and eosinophilic esophagitis," by the DGVS.

De-Prescribing Proton Pump Inhibitors in Patients With End Stage Kidney Disease: A Quality Improvement Project

Background:

Proton pump inhibitors (PPIs) are widely prescribed and may be associated with harm; hypomagnesemia and reduced effectiveness of calcium carbonate phosphate binders may be important in end-stage kidney disease (ESKD).

Objectives:

Our objectives included (1) discontinuing PPIs and H2 blockers and (2) assessing the impact on serum magnesium and markers of mineral metabolism.

Design:

Prospective cohort.

Setting:

Satellite hemodialysis unit of a tertiary care hospital.

Patients:

Incident and prevalent patients with ESKD treated with hemodialysis.

Measurements:

We assessed the impact of stopping PPI/H2 blockers in patients who did not have an absolute indication as per guidelines in the general population; serum magnesium, calcium, and phosphate were measured before and approximately 8 weeks later. Analysis of variance (ANOVA) test and Kruskal-Wallis was used to describe the population. Wilcoxon signed rank test for the paired change scores (from pre to post)

Methods:

The electronic medical record (EMR) was extensively searched for absolute indications for a PPI. Results were reviewed with the primary nephrology team before approaching patients about stopping the PPI. Basic demographic information and select medications were also collected.

Results:

Electronic medical records were reviewed for 179 patients, 74 had a PPI or H2 antagonist or both on their medication list (43%); 23 (31%) were assessed as appropriate. After primary team and patient review, 29 patients agreed to a trial of PPI withdrawal. Fourteen patients restarted their PPI, most for gastroesophageal reflux disease. Three patients had a GI bleed, 1 fatally. Serum calcium (P = .17) and the dose of phosphate binders (P = .075) did not change but serum phosphate increased (1.55 [0.29] to 1.85 [0.34] mmol/L; P = .0005). Serum magnesium also increased (1.01 [0.16] to 1.06 [0.14] mmol/L; P = .01).

Limitations:

Small patient numbers and observational nature of the study does not establish causation in this population at high risk to experience a gastrointestinal bleed.

Conclusions:

Our results suggest that PPI deprescribing as recommended in the general population may be associated with harm in patients with ESKD and requires further study.

Trial Registration:

Not registered.

Prescribing trends of proton pump inhibitors, antipsychotics and benzodiazepines of medicare part d providers

Background

Proton pump inhibitors, benzodiazepines, and antipsychotics are considered potentially inappropriate medications in older adults according to the American Geriatric Society Beers Criteria, and deprescribing algorithms have been developed to guide use of these drug classes. The objective of this study was to describe the number of beneficiaries prescribed these medications, provider specialty and regional trends in prescribing, and the aggregate costs for these claims in Medicare Part D.

Methods

This was a retrospective cross-sectional study using publicly available Medicare Provider Utilization and Payment Data: Part D Prescriber data for years 2013–2019. Descriptive statistics and the Cochrane-Armitage test were used to summarize the trends.

Results

Overall, 30.1%, 25.6%, 4.6% of Medicare Part D beneficiaries had a proton pump inhibitor, benzodiazepine, and antipsychotic claim in 2013, respectively. These rates decreased to 27.5%, 17.5%, 4.1% in 2019 (p-value < 0.0001). However, the number of standardized 30-day claims increased from 63 million in 2013 to 84 million in 2019 for proton pump inhibitors, remained steady for benzodiazepines and slightly increased (10 million to 13 million) for antipsychotics. Total aggregate costs decreased by almost $1.5 billion for proton pump inhibitor, $100 million for benzodiazepine, and $700 million for antipsychotic from 2013 to 2019 (p-value < 0.0001). Almost 93% of gastroenterologists prescribed a proton pump inhibitor, and 60% of psychiatrists prescribed benzodiazepines and antipsychotics all seven years. The Other region had the highest percentage of providers prescribing all three classes and the highest number of standardized 30-day benzodiazepine claims.

Conclusions

The overall rate of use of proton pump inhibitors, benzodiazepines, and antipsychotics decreased from 2013–2019 among Medicare Part D beneficiaries. Despite the increase in raw number of standardized 30-day claims, the costs decreased which is likely due to generics made available. These prescribing trends may aid in identifying and targeting potential deprescribing interventions.

Deprescribing Inappropriate Proton Pump Inhibitors in a Family Medicine Residency Practice Office

INTRODUCTION

Proton pump inhibitors (PPIs) are often prescribed beyond their medically-approved duration of use. Long-term PPI use has been linked with numerous adverse effects and contributes to polypharmacy. This study sought to understand the effect of evidence-based education to resident and faculty physicians on deprescribing inappropriate PPIs. We hypothesized that this educational intervention would result in fewer inappropriate PPI prescriptions.

METHODS

We performed a chart review on all adult patients in a family medicine residency program practice, identifying those inappropriately taking PPIs. All physicians in the practice participated in an educational intervention regarding deprescribing inappropriate PPIs and were given frequent reminders to continue their deprescribing efforts. We reviewed charts at the end of the study to identify patients with successful deprescribing attempts.

RESULTS

Of the 187 patients prescribed inappropriate PPIs in the study, 100 remained on PPIs at the end of the study (46.6% success rate). There was a significant decrease in the number of patients inappropriately prescribed PPIs by each physician over the course of the study, from a mean of 17.0 (beginning) to 9.1 (end).

CONCLUSION

Physician education with reminders is an effective means of reducing the number of inappropriate PPIs prescribed in a family medicine residency practice. Future studies could investigate the effectiveness of educational interventions with other medication classes that are often prescribed inappropriately.

Prevalence and Risk Factors for Inappropriate Continuation of Proton Pump Inhibitors After Discharge From the Intensive Care Unit

OBJECTIVE

To determine the prevalence and risk factors for inappropriate discharge on proton pump inhibitor (PPI) therapy started in the intensive care unit (ICU) for stress ulcer prophylaxis.

PATIENTS AND METHODS

This was a retrospective cohort study of adults initiated on treatment with a PPI in any of 9 affiliated ICUs from January 1, 2014, to December 31, 2018. Patients were excluded if they had an appropriate long-term PPI indication. Logistic regression modeling was used to identify characteristics associated with discharge on treatment with an inappropriate PPI.

RESULTS

Of 24,751 patients admitted to an ICU, 4127 were initiated on treatment with a new PPI, with 2467 (60%) lacking a long-term PPI indication. Of these 2467, a total of 1122 (45%) were continued on PPI therapy after transfer to the floor and 668 (27%) were discharged on PPI therapy. On multivariable analysis, risk factors for inappropriate discharge on PPI therapy included having an upper endoscopy (adjusted odds ratio [aOR], 1.70; 95% CI, 1.08-2.66), admission to the surgical compared with medical ICU (aOR, 2.03; 95% CI, 1.32-3.10), and discharge to a nursing home or rehabilitation facility (aOR, 1.43; 95% CI, 1.04-1.96; and aOR, 2.29; 95% CI, 1.62-3.24, respectively).

CONCLUSION

Among patients started on treatment with a PPI in the ICU without an indication for outpatient PPI use, 27% (668 of 2467) were nonetheless discharged on PPI therapy. Medically complex and surgical ICU patients are at increased risk for receiving PPIs without appropriate documented indications, and careful review of medication lists at discharge should occur in these high-risk groups.

Community-based pharmacists' role in deprescribing: A systematic review

AIMS

Community-based pharmacists are an important stakeholder in providing continuing care for chronic multi-morbid patients, and their role is steadily expanding. The aim of this study is to examine the literature exploring community-based pharmacist-initiated and/or -led deprescribing and to evaluate the impact on the success of deprescribing and clinical outcomes.

METHODS

Library and clinical trials databases were searched from inception to March 2020. Studies were included if they explored deprescribing in adults, by community-based pharmacists and were available in English. Two reviewers extracted data independently using a pre-agreed data extraction template. Meta-analysis was not performed due to heterogeneity of study designs, types of intervention and outcomes.

RESULTS

A total of 24 studies were included in the review. Results were grouped based on intervention method into four categories: educational interventions; interventions involving medication review, consultation or therapy management; pre-defined pharmacist-led deprescribing interventions; and pharmacist-led collaborative interventions. All types of interventions resulted in greater discontinuation of medications in comparison to usual care. Educational interventions reported financial benefits as well. Medication review by community-based pharmacist can lead to successful deprescribing of high-risk medication, but do not affect the risk or rate of falls, rate of hospitalisations, mortality or quality of life. Pharmacist-led medication review, in patients with mental illness, resulting in deprescribing improves anticholinergic side effects, memory and quality of life. Pre-defined pharmacist-led deprescribing did not reduce healthcare resource consumptions but can contribute to financial savings. Short follow-up periods prevent evaluation of long-term sustainability of deprescribing interventions.

CONCLUSION

This systematic review suggests community-based pharmacists can lead deprescribing interventions and that they are valuable partners in deprescribing collaborations, providing necessary monitoring throughout tapering and post-follow-up to ensure the success of an intervention.

Deprescribing medications that may increase the risk of hepatic encephalopathy: A qualitative study of patients with cirrhosis and their doctors

Background and Aims

Multiple medications are associated with an increased risk of incident hepatic encephalopathy. Despite this known risk, medications such as opioids, benzodiazepines, gabapentin/pregabalin, and/or proton pump inhibitors are increasingly prescribed to persons with cirrhosis. Deprescribing is a promising intervention to reduce the burden of hepatic encephalopathy. Given that deprescribing has not been trialed in cirrhosis, we evaluated the barriers and facilitators to safe and successful deprescribing in cirrhosis.

Methods

We conducted, transcribed, and analyzed semi‐structured interviews using qualitative methodology with 22 subjects. This included eight patients with cirrhosis and recent use of opiates, benzodiazepines, gabapentin/Lyrica, and/or proton pump inhibitors as well as 14 providers (primary care, transplant surgery, transplant hepatology). Interviews explored opinions, behaviors, and understanding surrounding the risks and benefits of deprescribing.

Results

Major provider‐specific barriers included deferred responsibility of the deprescribing process, knowledge gaps regarding the risk of hepatic encephalopathy associated with medications (e.g., proton pump inhibitors) as well as the safe method of deprescription (i.e., benzodiazepines), and time constraints. Patient‐specific barriers included knowledge gaps regarding the cirrhosis‐specific risks of their medications and anxiety about the recurrence of symptoms after medication discontinuation. Patients uniformly reported trust in their provider's opinions on risks and wished for more comprehensive education during or after visits. Providers uniformly reported support for deprescription resources including pharmacist or nurse outreach.

Conclusion

Given knowledge of medication risks related to hepatic encephalopathy in patients with cirrhosis, deprescribing is universally seen as important. Knowledge gaps, inaction, and uncertainty regarding feasible alternatives prevent meaningful implementation of deprescription. Trials of protocolized pharmacy‐based deprescribing outreach and patient‐facing education on risks are warranted.

Summarize the established knowledge on this subject

Hepatic encephalopathy (HE) is a morbid complication of cirrhosis.

The risk of HE may be increased by psychoactive medications and proton pump inhibitors.

Deprescribing is felt to be a promising approach to HE prevention.

What are the significant and/or new findings of this study?

Patients are unaware of how their medications influence the risk of HE.

Patients are willing to follow physician recommendations regarding deprescribing but are afraid of worsening symptoms.

Physicians do not feel comfortable deprescribing opioids or benzodiazepines.

Physicians do not feel responsible or equipped with the resources for deprescribing.

National trends in prescription proton pump inhibitor use and expenditure in the United States in 2002-2017

OBJECTIVES

In the United States, proton pump inhibitors (PPIs) are one of the most commonly prescribed classes of drugs, but contemporary data on national-level utilization patterns for PPI use are limited. This study examined the trends in prescription PPI use and expenditures, overall and by patient subgroups, and identified predictors of PPI use.

METHODS

Prescription PPI use was identified from the 2002-2017 Medical Expenditure Panel Survey data using the brand and generic names. Trends in PPI use were examined overall and by patients' sociodemographic characteristics and disease status. Trends in brand and generic PPI users and total and average PPI expenditures were also examined. A multivariable model was used to identify patient factors associated with PPI use.

RESULTS

The overall proportion of PPI users increased from 5.70% in 2002-2003 to 6.73% in 2016-2017 (P value = 0.011). Increased trends in PPI use were observed among U.S. adults aged 65 years and older, both males and females, non-Hispanic whites, non-Hispanic blacks, Hispanics, Asians, in all 4 geographic regions, with public health insurance, and those who were obese (all P value < 0.05). Whereas PPI use increased significantly, the average PPI expenditure per patient decreased significantly. Multivariable results found that participants who were aged 25 years or older, were female, were non-Hispanic whites, resided in the Northeast, had higher incomes, had public or private health insurance, were obese, were married had a higher likelihood of using PPIs.

CONCLUSION

Increased PPI use was observed among most of the patient subgroups. Understanding the utilization patterns of PPIs could help practitioners identify potential treatment disparities and monitor the safety of PPI use.
