Prescription Pattern of Proton Pump Inhibitors at Hospital Admission and Discharge

The silent epidemic: Inappropriate use of proton pump inhibitors among hospitalized patients

BACKGROUND AND STUDY AIMS

There is an increasing trend to inappropriately prescribe proton pump inhibitors (PPIs) in different clinical settings despite the reported adverse outcomes. This study aimed to assess (1) the prevalence of potentially inappropriate use of PPIs and its associated risk factors among hospitalized patients, at pre-admission and discharge and (2) the prevalence of valid indications of PPIs use without prescription.

PATIENTS AND METHODS

A retrospective observational study was performed at a single center, examining the records of patients aged ≥18 years who were admitted to the Family Medicine inpatient service over a one-year period. The appropriateness of PPIs use was assessed against a set of pre-approved indications.

RESULTS

A total of 289 patients were included in the analysis. Of these, 34.67 % were taking PPIs upon admission, increasing to 43.67 % at discharge (p < 0.001). Inappropriate PPI use was identified in 51.92 % at pre-admission and 57.25 % at discharge. Multivariate analysis identified significant factors contributing to inappropriate PPI use: polypharmacy at both admission and discharge (OR = 4.587, p = 0.031), and the presence of two or more comorbidities at discharge (OR = 5.421, p = 0.011; OR = 13.005, p = 0.037). Age ≤65 was associated with increased inappropriate use only at discharge (p < 0.003). Conversely, appropriate prescribing was noted in patients over 65 and those on antiplatelet therapy, aligning with clinical guidelines.

CONCLUSIONS

This study reveals a high prevalence of inappropriate PPI use among hospitalized patients, notably increasing from admission to discharge. Key contributors to inappropriate PPI usage included polypharmacy and high comorbidity scores at discharge, particularly in patients under 65. This emphasizes the need for targeted interventions to optimize PPI prescribing practices in clinical settings.

Proton Pump Inhibitors: Rational Use and Use-Reduction - The Windsor Workshop

BACKGROUND

Despite deprescribing initiatives to curb overutilization of proton pump inhibitors (PPIs), achieving meaningful reductions in PPI use is proving a challenge.

SUMMARY

An international group of primary care doctors and gastroenterologists examined the literature surrounding PPI use and use-reduction to clarify: (i) what constitutes rational PPI prescribing; (ii) when and in whom PPI use-reduction should be attempted; and (iii) what strategies to use when attempting PPI use-reduction.

KEY MESSAGES

Before starting a PPI for reflux-like symptoms, patients should be educated on potential causes and alternative approaches including dietary and lifestyle modification, weight loss, and relaxation strategies. When commencing a PPI, patients should understand the reason for treatment, planned duration, and review date. PPI use at hospital discharge should not be continued without a recognized indication for long-term treatment. Long-term PPI therapy should be reviewed at least annually. PPI use-reduction should be based on the lack of a rational indication for long-term PPI use, not concern for PPI-associated adverse events. PPI use-reduction strategies involving switching to on-demand PPI or dose tapering, with rescue therapy for rebound symptoms, are more likely to succeed than abrupt cessation.

Time-Varying Use of Proton Pump Inhibitors and Cognitive Impairment and Dementia: A Real-World Analysis from Germany

BACKGROUND

Cumulative evidence of dementia risk in patients taking proton pump inhibitors (PPIs) is still inconclusive, probably due to a variety of study designs.

OBJECTIVE

This study aimed to compare how the association between dementia risk and use of PPIs differs by different outcome and exposure definitions.

METHODS

We conceptualized a target trial using claims data with 7,696,127 individuals aged 40 years or older without previous dementia or mild cognitive impairment (MCI) from the Association of Statutory Health Insurance Physicians in Bavaria. Dementia was defined as either including or excluding MCI to compare how the results alter by different outcome definitions. We used weighted Cox models to estimate the PPI initiation effect on dementia risk and weighted pooled logistic regression to assess the effect of time-varying use versus non-use during 9 years of study period, including 1 year of wash-out period (2009-2018). The median follow-up time of PPI initiators and non-initiators was 5.4 and 5.8 years, respectively. We also evaluated the association between each PPI agent (omeprazole, pantoprazole, lansoprazole, esomeprazole, and combined use) and dementia risk.

RESULTS

A total of 105,220 (3.6%) PPI initiators and 74,697 (2.6%) non-initiators were diagnosed with dementia. Comparing PPI initiation with no initiation, the hazard ratio (HR) for dementia was 1.04 [95% confidence interval (CI) 1.03-1.05]. The HR for time-varying PPI use versus non-use was 1.85 (1.80-1.90). When MCI was included in the outcome, the number of outcomes increased to 121,922 in PPI initiators and 86,954 in non-initiators, but HRs remained similar, showing 1.04 (1.03-1.05) and 1.82 (1.77-1.86), respectively. Pantoprazole was the most frequently used PPI agent. Although the estimated HRs for the time-varying use effect of each PPI showed different ranges, all agents were associated with an increased dementia risk.

CONCLUSION

Our large study supports existing evidence that PPI use is related to an increased risk of dementia.

Evaluation of Proton Pump Inhibitors Prescribing Among Hospitalized Patients: A Cross-Sectional Study

Background

Proton pump inhibitors (PPIs) are the most effective agents for managing acid-related disorders. However, inappropriate prescribing of PPIs is becoming an issue of concern.

Objective

This study aimed to assess the appropriate utilization of PPIs in terms of indication, dose, frequency, and route of administration during admission and discharge. Furthermore, direct costs associated with inappropriate PPI use were calculated.

Methods

A descriptive cross-sectional study was conducted at the internal medicine department of a tertiary hospital in Palestine from January 1, 2021, to June 30, 2021. The medical records of patients aged 18 years or older, hospitalized for 48 hours or more, and receiving oral or intravenous (IV) PPIs during their stay were collected and evaluated for the appropriateness of PPIs prescribed according to clinical guidelines.

Results

Of 262 patients, 80.2% had an appropriate indication for prophylaxis (67.6%) or treatment (12.6%). A total of 230 patients were prescribed IV pantoprazole.182 (79.1%) had an appropriate indication, whereas 122/182 (67%) received IV PPI instead of oral without an appropriate indication. Of the 32 patients who received 20 mg of oral omeprazole, 28 (87.5%) had an appropriate indication, dose, and route of administration, whereas 16/28 (57.1%) had an inappropriate frequency. At discharge, 32.5% of patients were discharged with unnecessary PPI prescriptions. The total direct cost of inappropriate PPI Indications and route of administration in 188 patients over six months was $1518.

Conclusion

This study showed that most patients received a PPI for an appropriate indication with the correct dose. However, a high prevalence of inappropriate IV pantoprazole administration was observed, resulting in the highest costs, demonstrating the importance of correctly ordering IV medications. Adherence to clinical guidelines, such as those of the American College of Gastroenterology (ACG), will improve the appropriateness of PPI prescribing, prevent complications, and reduce healthcare costs.

Proton pump inhibitor use and appropriateness analysis: a snapshot from a secondary care hospital

Objectives

Proton pump inhibitors (PPIs) have become one of the most frequently prescribed drugs since their introduction 30 years ago. Effectiveness and safety profile of PPIs has led to their overutilization and has exposed patients to a number of potential risks. The objective of this study was to evaluate the use of PPIs in a secondary care hospital in the United Arab Emirates.

Methods

This prospective observational drug-utilization study was conducted in patients receiving treatment with PPIs and admitted to internal medicine wards of the study site. Electronic patient case records were reviewed and data on PPI prescribing was collected and analysed. Appropriateness of PPI use was assessed as per international guidelines.

Key findings

Out of 172 patients enrolled, 53.5% were females with median age of 57 years (34.3, 71.0). Four different PPIs were prescribed to study patients, pantoprazole (86.6%), esomeprazole (5.8%), rabeprazole (4.1%) and omeprazole (3.5%). Ninety-two (53.5%) patients were prescribed intravenous PPI, whereas 80 (46.5%) patients were given PPI in oral form. Overall, 103 (59.9%) patients had inappropriate PPI prescriptions. Of these inappropriate prescriptions, 22 patients had no clear indication for PPI use and for 16 patients; PPIs were indicated for stress ulcer prophylaxis in low-risk category. Corticosteroid use [odds ratio (OR): 4.34, 95% confidence interval (CI): 1.22–15.46; P = 0.023] was significantly associated with greater odds of inappropriate PPI use.

Conclusions

We report a high prevalence of inappropriate PPI prescribing among the hospitalized patients in our study. Inappropriate PPI prescribing is a concerning issue and collective efforts should be made to check and minimize the same.

Effect of frequently prescribed drugs on gastric cancer risk

Gastric cancer is the fifth leading cancer worldwide. Infection with Helicobacter pylori represents the major risk factor, but only a small fraction of infected individuals will develop neoplasia. The progression of advanced gastric lesions to cancer is influenced by characteristics of the bacterial strain, host genetic and environmental factors. Recently, the effect of medications on gastric cancer risk has gained interest, because many commonly prescribed drugs affect gastric homeostasis. While non-steroidal anti-inflammatory drugs (NSAIDs) are a frequent cause of gastric ulcer disease, low-dose aspirin has been propagated for chemoprevention of various tumour entities. Beneficial effects of cyclooxygenase-inhibition for gastric cancer prevention is plausible, but its clinical relevance remains unclear. Furthermore, anti-tumorous effects have been postulated for statins and metformin. On the contrary, proton pump inhibitors (PPIs), which are commonly used for prevention of gastric ulcers and bleeding, have been associated with an increased gastric cancer risk in large observational studies. Most of these observations still require confirmation in prospective controlled trials. NSAIDs, statins and metformin have also been investigated as concomitant cancer treatment, but studies did not show convincing results to date. Here, we review the available evidence and possible mechanisms for the role of PPIs, NSAIDs, statins and metformin in gastric carcinogenesis, and discuss possible implications for clinical practice.

Inappropriate Prescribing of Proton Pump Inhibitors in Outpatient Clinics

Proton pump inhibitors are the commonly prescribed drugs for acid-related disorders. However, many of those prescriptions are inappropriate in inpatient and outpatient settings according to the recommended guidelines. Many studies have been conducted in inpatient clinics, but data about the appropriateness of proton pump inhibitor prescribing in outpatient clinics are scarce. Therefore, the aim of this study was to determine inappropriate proton pump inhibitor prescribing rates among patients admitted to a tertiary hospital family medicine outpatient clinic. A total of 259 patients (median age = 59 years; 72.6% women) were enrolled into the study and 35.9% of them had no proper indications to utilize proton pump inhibitors. Inappropriate proton pump inhibitor usage rate was significantly higher in patients older than 60 years compared with their younger counterparts (62.4% vs. 37.6%; p = .001). The most frequent reason to use a proton pump inhibitor with nonapproved indications was polypharmacy (41.9%). Despite endoscopic evaluation, 41.9% of the patients received a proton pump inhibitor without an approved indication. A significant proportion of nonindicated prescriptions were a consequence of continued prescribing without re-evaluating patients in outpatient clinics. Consideration of proton pump inhibitor indications according to the guidelines in every admission may prevent inappropriate prescriptions.

Proton pump inhibitor utilisation and potentially inappropriate prescribing analysis: insights from a single-centred retrospective study

OBJECTIVES

This study aimed to characterise the prescribing patterns and evaluate the appropriateness of the prescribed proton pump inhibitors (PPIs) in adult patients via a review of electronic medical records in a single-centred hospital.

DESIGN

All patients admitted to the outpatient department of Jinshan Hospital, Fudan University, Shanghai, between 1 January 2018 and 31 December 2018 were evaluated. Individuals aged 18 years or above and with at least one dispensing for PPIs were identified as PPI users. New PPI users were defined as a subject who did not receive any dispensing for PPIs in the year prior to the index date. Baseline characteristics of PPI users and their therapies were described by treatment indication, economic indicators and co-prescription, overall and separately.

SETTING

The prescription database was retrieved from the hospital information system of Jinshan Hospital, Fudan University.

RESULTS

Among 18 435 identified PPI users in 2018, 14 219 patients (aged 18 years or above) who had at least one dispensing PPIs were new users (77%), and among them, men accounted for 47%. The mean treatment duration was 23 days. Omeprazole was the most commonly prescribed drug. PPIs are inappropriately prescribed in 50% (13 589/25 850) of prescriptions. Prescription appropriateness analysis indicated that the unapproved indications for PPI new users accounted for 47%; among them, the proportion of gastritis diagnosis was 34%. The proportion of PPI new users with co-prescription of glucocorticosteroids (GCs) who have risk factors accounted for 24% and lower than other co-prescription. A majority of PPI users (73%) reported high-dose PPI prescription. The defined daily dose of oral pantoprazole was the highest, and injectable omeprazole had the highest defined daily cost. In contrast, only the drug utilisation index value of oral esomeprazole was less than 1.0.

CONCLUSION

The results indicate the challenge of PPI use was accompanied by unapproved indications, frequent inappropriate co-prescription with GCs and excessive dosages. Efforts should be paid to promote rational use and ensure the choice of suitable PPI therapy in the future.
