Estimating the economic effect of harm associated with high risk prescribing of oral non-steroidal anti-inflammatory drugs in England: population based cohort and economic modelling study.

OBJECTIVES: To quantify prevalence, harms, and NHS costs in England of problematic oral non-steroidal anti-inflammatory drug (NSAID) prescribing in high risk groups. DESIGN: Population based cohort and economic modelling study. SETTING: Economic models estimating patient harm associated with NSAID specific hazardous prescribing events, and cost to the English NHS, over a 10 year period, were combined with trends of hazardous prescribing event to estimate national levels of patient harm and NHS costs. PARTICIPANTS: Eligible participants were prescribed oral NSAIDs and were in five high risk groups: older adults (≥65 years) with no gastroprotection; people who concurrently took oral anticoagulants; or those with heart failure, chronic kidney disease, or a history of peptic ulcer. MAIN OUTCOME MEASURES: Prevalence of hazardous prescribing events, by each event and overall, discounted quality adjusted life years (QALYs) lost, and cost to the NHS in England of managing harm. RESULTS: QALY losses and cost increases were observed for each hazardous prescribing event (v no hazardous prescribing event). Mean QALYs per person were between 0.01 (95% credibility interval (CI) 0.01 to 0.02) lower with history of peptic ulcer, to 0.11 (0.04 to 0.19) lower with chronic kidney disease. Mean cost increases ranged from a non-statistically significant £14 (€17; $18) (95% CI -£71 to £98) in heart failure, to a statistically significant £1097 (£236 to £2542) in people concurrently taking anticoagulants. Prevalence of hazardous prescribing events per 1000 patients ranged from 0.11 in people who have had a peptic ulcer to 1.70 in older adults. Nationally, the most common hazardous prescribing event (older adults with no gastroprotection) resulted in 1929 (1416 to 2452) QALYs lost, costing £2.46m (£0.65m to £4.68m). The greatest impact was in people concurrently taking oral anticoagulants: 2143 (894 to 4073) QALYs lost, costing £25.41m (£5.25m to £60.01m). Over 10 years, total QALYs lost were estimated to be 6335 (4471 to 8658) and an NHS cost for England of £31.43m (£9.28m to £67.11m). CONCLUSIONS: NSAIDs continue to be a source of avoidable harm and healthcare cost in these five high risk populations, especially in inducing an acute event in people with chronic condition and people taking oral anticoagulants.

Family-based Helicobacter pylori infection control and management strategy and screen-and-treat strategy are highly cost-effective in preventing multiple upper gastrointestinal diseases in Chinese population at national level.

BACKGROUND: The overall benefits of the newly introduced family-based Helicobacter pylori (H. pylori) infection control and management (FBCM) and screen-and-treat strategies in preventing multiple upper gastrointestinal diseases at national level in China have not been explored. We investigate the cost-effectiveness of these strategies in the whole Chinese population. MATERIALS AND METHODS: Decision trees and Markov models of H. pylori infection-related non-ulcer dyspepsia (NUD), peptic ulcer disease (PUD), and gastric cancer (GC) were developed to simulate the cost-effectiveness of these strategies in the whole 494 million households in China. The main outcomes include cost-effectiveness, life years (LY), quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER). RESULTS: When compared with no-screen strategy, both FBCM and screen-and-treat strategies reduced the number of new cases of NUD, PUD, PUD-related deaths, and the prevalence of GC, and cancer-related deaths. The costs saved by these two strategies were $1467 million and $879 million, quality-adjusted life years gained were 227 million and 267 million, and life years gained were 59 million and 69 million, respectively. Cost-effectiveness analysis showed that FBCM strategy costs -$6.46/QALY and -$24.75/LY, and screen-and-treat strategy costs -$3.3/QALY and -$12.71/LY when compared with no-screen strategy. Compared to the FBCM strategy, the screen-and-treat strategy reduced the incidence of H. pylori-related diseases, added 40 million QALYs, and saved 10 million LYs, but at the increased cost of $588 million. Cost-effectiveness analysis showed that screen-and-treat strategy costs $14.88/QALY and $59.5/LY when compared with FBCM strategy. The robustness of the results was also verified. CONCLUSIONS: Both FBCM and screen-and-treat strategies are highly cost-effective in preventing NUD, PUD, and GC than the no-screen strategy in Chinese families at national level. As FBCM strategy is more practical and efficient, it is expected to play a more important role in preventing familial H. pylori infection and also serves as an excellent reference for other highly infected societies.

Clinical and economic impact of "triple therapy" for Helicobacter pylori eradication on peptic ulcer disease in Australia.

BACKGROUND: Helicobacter pylori infection has had a major impact on the global health of billions of people. Triple therapy was extensively used in Australia by 1986 for H pylori eradication after its discovery in 1984 and was critical in reducing the morbidity and mortality associated with this infection. AIMS: This study analyzed hospital admission, mortality, and therapeutic data to determine the economic and clinical impact that antibiotic triple therapy had on peptic ulcer disease (PUD) in Australia. METHODS: An analysis of indirect and direct cost-savings in Australia between 1990 and 2015 associated with triple therapy and the impact on PUD mortality and hospital admissions. RESULTS: The direct and indirect impacts of PUD treated by triple therapy between 1990 and 2015 suggest that triple therapy is likely to have prevented 18 665 deaths, and saved 258 887 life years and 33 776 productive life years. The total savings, over the 26-year period, including direct and indirect costs, are calculated to be $10.03 billion, equating to an average annual saving of $393.419 million. CONCLUSIONS: This study highlights the enormous benefits to Australia's health care of the discovery of triple therapy, a relatively low-cost antibiotic regimen which brought considerable savings via the reduction in morbidity (hospital admissions) and mortality related to PUD. It is likely that benefits of similar scale occurred internationally.

Trends and outcomes of peptic ulcer disease in patients with cirrhosis.

BACKGROUND: Peptic ulcer disease (PUD) is more prevalent in cirrhotic patients and it has been associated with poor outcomes. However, there are no population-based studies from the United States (U.S.) that have investigated this association. Our study aims to estimate the incidence trends, predictors, and outcomes PUD patients with underlying cirrhosis. METHODS: We analyzed Nationwide Inpatient Sample (NIS) and Healthcare Cost and Utilization Project (HCUP) data for years 2002-2014. Adult hospitalizations due to PUD were identified by previously validated ICD-9-CM codes as the primary diagnosis. Cirrhosis was also identified with presence of ICD-9-CM codes in secondary diagnosis fields. We analyzed trends and predictors of PUD in cirrhotic patients and utilized multivariate regression models to estimate the impact of cirrhosis on PUD outcomes. RESULTS: Between the years 2002-2014, there were 1,433,270 adult hospitalizations with a primary diagnosis of PUD, out of which 70,007 (4.88%) had cirrhosis as a concurrent diagnosis. There was a significant increase in the proportion of hospitalizations with a concurrent diagnosis of cirrhosis, from 3.9% in 2002 to 6.6% in 2014 (p < 0.001). In an adjusted multivariable analysis, in-hospital mortality was significantly higher in hospitalizations of PUD with cirrhosis (odd ratio [OR] 1.78; 95% confidence interval [CI] 1.63-1.97; P < 0.001), however, there was no difference in the discharge to facility (OR 1.00; 95%CI 0.94 - 1.07; P = 0.81). Moreover, length of stay (LOS) was also higher (6 days vs. 4 days, P < 0.001) among PUD with cirrhosis. Increasing age and comorbidities were associated with higher odds of in-hospital mortality among PUD patients with cirrhosis. CONCLUSION: Our study shows that there is an increased hospital burden as well as poor outcomes in terms of higher in-hospital mortality among hospitalized PUD patients with cirrhosis. Further studies are warranted for better risk stratification and improvement of outcomes.

Helicobacter pylori "Test-and-Treat" strategy with urea breath test: A cost-effective strategy for the management of dyspepsia and the prevention of ulcer and gastric cancer in Spain-Results of the Hp-Breath initiative.

BACKGROUND: Data from clinical trials comparing Helicobacter pylori (H. pylori) management strategies in patients with dyspepsia are limited. Cost-effectiveness simulation models might help to identify the optimal strategy. OBJECTIVE: To assess the cost-effectiveness of the H. pylori "Test and Treat" (T&T) strategy including the use of urea breath test (UBT) vs symptomatic treatment (ST) and vs upper gastrointestinal endoscopy (UGE) as a first procedure in patients with dyspepsia. METHODS: Three main strategies: "T&T" strategy including the use of UBT, "UGE" and "ST" have been compared using cost-effectiveness models developed in accordance with the Spanish medical practice. For the model simulations, a time horizon of 4 weeks was considered for the endpoint "Dyspepsia symptoms relief" and 10 years when using "Peptic ulcer avoided" and "Gastric cancer avoided" endpoints. RESULTS: For the endpoint "Dyspepsia symptoms relief", T&T strategy appears to be the most cost-effective (883€/success) compared to UGE strategy and to ST strategy (respectively 1628€ and 990€/success). For the endpoint "Probability of peptic ulcer", the T&T strategy appears to be the most cost-effective (421€/peptic ulcer avoided/y) compared to UGE strategy and ST strategy (respectively 728€ and 632€/peptic ulcer avoided/y). For the endpoint "Gastric cancer avoided", the T&T strategy appears to be the most cost-effective (524€/gastric cancer avoided/y) compared to UGE strategy and "ST" strategy (respectively 716€ and 696€/gastric cancer avoided/y). CONCLUSIONS: T&T strategy including the use of UBT is the most cost-effective medical approach for management of dyspepsia and for the prevention of ulcer and gastric cancer.

Clipping Over the Scope for Recurrent Peptic Ulcer Bleeding is Cost-Effective as Compared to Standard Therapy: An Initial Assessment.

Clipping over the scope (C-OTS) is a novel closure technique used for the treatment of nonvariceal gastrointestinal bleeding, especially for high-risk lesions. C-OTS devices cost more than clipping through the scope and thermal devices. The high upfront cost of C-OTS may pose a barrier to its use and the cost-effectiveness of C-OTS for peptic ulcer disease bleeding is unknown. Cost-effectiveness studies of C-OTS for peptic ulcer bleeding as both first-line and second-line therapy can provide the current estimate of the conditions in which the use of C-OTS is cost-effective and give insights of the determinants to the cost-effectiveness of C-OTS.

Peptic ulcer Disease drugs usage patterns and its economic burden in a tertiary health institution in Niger Delta, Nigeria

Background: Drug utilization evaluation for peptic ulcer disease and its cost implication are rare in Niger Delta. The objective of the study was to evaluate drug usage pattern in peptic ulcer diseases as well as its cost implications.Methods: The cross sectional drug use evaluation study involving the use of questionnaire and patient case notes was carried out in a tertiary health institution. The validated pretested questionnaire was interviewer administered to 300 patients sampled consecutively followed by a retrospective review of their respective case notes between April to November 2013. Information collected include risk factors, prescribed drugs, Helicobacter pylori assay test results among others. Cost of each drug and therapy were then computed appropriately. Data was analyzed using Statistical package for Social Sciences (SPSS) version 20, Microsoft Excel and Graph Pad Prism for windows Instat Version 3.Results: Out of the 300 patients, H. pylori test was conducted in 262 (87.3%) while the presence or absence of the organisms could not be confirmed in the remaining 38 subjects. Out of the 262 patients with H. pylori test results, only 166 representing 63.4% were positive. History of non-steroidal anti-inflammatory drugs (NSAID) usage was very high among the subjects (250; 83.3%) and highest for ibuprofen 146 (48.7%). The most prescribed drugs were antacids (268; 89.3%), amoxicillin (165; 55.0%), and a combined formulation of omeprazole, tinidazole, and clarithromycin in 140 (46.7%) subjects, followed by omeprazole alone (125; 41.7%).The national direct cost implication for the estimated 17.6 million is in the range of NGN186,849,000,000.00 ($958,200,000.00), out which NGN109,867,000,000.00($563,420,513.00) was for PUD drugs (50.9%) and NGN32,698,575,000.00 ($167,685,000.00) for H. pylori tests (17.5%), while the remaining 31.7% valued at NGN59,231,133,000.00 ($303,749,400.00) was for non-ulcer drugs, personnel and transportation.Conclusion: The pattern of drugs usage is consistent with standard treatment guidelines. Peptic ulcer drugs for the 300 subjects constituted NGN1,618,641 ($8300.72) which represents 73.0% of the total amount spent on drugs. The national direct cost of PUD is close to NGN200 billion ($1.04 billion). Updated information on drug usage and their costs is needed for improved usage and system efficiency

Incidence and cost of stress ulcer prophylaxis after discharge from the intensive care unit: a retrospective study.

OBJECTIVE: To describe current patterns in initiation and cessation of proton pump inhibitors (PPIs) for stress ulcer prophylaxis (SUP) in intensive care units, and to assess the costs associated with inappropriate (non-evidence-based) SUP. DESIGN, SETTING AND PARTICIPANTS: Retrospective observational study in five ICUs in Western Australia. We assessed the medical records of consecutive patients admitted to the ICUs between September 2013 and January 2015. Patients aged < 18 years were excluded. RESULTS: We included 531 patients in the study. Of the 184 patients in whom PPIs were initiated for SUP in the ICU, 90 (48.9%) were still taking the therapy at the time of discharge from hospital. A documented indication for ongoing therapy was present in only nine patients (10%). We assumed a 10-year life expectancy after ICU discharge and that most patients continued taking a PPI, and calculated an additional cost of $180.20 per patient admitted to the ICU. This was based only on unnecessary PPI costs (ignoring costs of managing additional adverse events). The direct cumulative annual cost to the WA health system of PPIs continued unnecessarily for patients at discharge from hospital is estimated to be $250 800 for each year they continue to receive them. CONCLUSION: A substantial proportion of patients prescribed SUP in the ICU continue receiving this therapy at hospital discharge despite no clear indication. In addition to potential adverse clinical effects, this is associated with major direct and indirect cost implications.

Stress ulcer prophylaxis with a proton pump inhibitor versus placebo in critically ill patients (SUP-ICU trial): study protocol for a randomised controlled trial.

BACKGROUND: Critically ill patients in the intensive care unit (ICU) are at risk of clinically important gastrointestinal bleeding, and acid suppressants are frequently used prophylactically. However, stress ulcer prophylaxis may increase the risk of serious adverse events and, additionally, the quantity and quality of evidence supporting the use of stress ulcer prophylaxis is low. The aim of the SUP-ICU trial is to assess the benefits and harms of stress ulcer prophylaxis with a proton pump inhibitor in adult patients in the ICU. We hypothesise that stress ulcer prophylaxis reduces the rate of gastrointestinal bleeding, but increases rates of nosocomial infections and myocardial ischaemia. The overall effect on mortality is unpredictable. METHODS/DESIGN: The SUP-ICU trial is an investigator-initiated, pragmatic, international, multicentre, randomised, blinded, parallel-group trial of stress ulcer prophylaxis with a proton pump inhibitor versus placebo (saline) in 3350 acutely ill ICU patients at risk of gastrointestinal bleeding. The primary outcome measure is 90-day mortality. Secondary outcomes include the proportion of patients with clinically important gastrointestinal bleeding, pneumonia, Clostridium difficile infection or myocardial ischaemia, days alive without life support in the 90-day period, serious adverse reactions, 1-year mortality, and health economic analyses. The sample size will enable us to detect a 20 % relative risk difference (5 % absolute risk difference) in 90-day mortality assuming a 25 % event rate with a risk of type I error of 5 % and power of 90 %. The trial will be externally monitored according to Good Clinical Practice standards. Interim analyses will be performed after 1650 and 2500 patients. CONCLUSION: The SUP-ICU trial will provide high-quality data on the benefits and harms of stress ulcer prophylaxis with a proton pump inhibitor in critically ill adult patients admitted in the ICU. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02467621 .

Acid Suppressive Therapy for Stress Ulcer Prophylaxis in Noncritically Ill Patients.

BACKGROUND: The current literature discourages the use of acid suppressive therapy (AST) for stress ulcer prophylaxis (SUP) in noncritically ill patients. However, several sources indicate that the majority of noncritically ill patients are given AST for SUP while there may only be a small proportion of high-risk patients who need SUP therapy. There is a new scoring system to aid practitioners in stratifying the risk of stress ulcer-related gastrointestinal bleeding in noncritically ill patients developed by Herzig et al and appropriately prescribe AST for SUP in this population. OBJECTIVE: Our primary objective was to determine the current usage of AST in noncritically ill patients at a tertiary teaching hospital and use the new scoring system to identify non-intensive care unit patients who were inappropriately given AST. METHODS: We retrospectively determined the percentage of noncritically ill patients who were given AST on medical floors between January 2010 and December 2012. After identifying these patients, we randomly selected a sample and retrospectively collected data from their medical record to determine the gastrointestinal bleeding risk score to determine if the patient was appropriately given AST. RESULTS: Of the 42 600 admissions, 22 949 (53.7%) noncritically ill patients were given AST. A total of 442 patients were randomly selected for data collection and 156 patients were excluded. Gastrointestinal bleeding risk score was calculated in 286 patients. This new risk stratification tool identified 253 (88.5%) patients to have a low (≤7) and low-medium risk score (8-9). CONCLUSIONS: A large percentage of noncritically ill patients were given AST during their hospital stay; 88.5% of these medications were given inappropriately to patients who were at extremely low risk of gastrointestinal bleeding. Using the above information and the AST prescribing patterns at our institution, we estimate a potential inpatient medication cost savings of $114 622 for the study period.

[Pharmacoeconomic evaluation of treatment in patients with Helicobacter pylori-associated diseases].

AIM: To estimate the pharmacoeconomic parameters of treatment in patients with Helicobacter pylori-associated diseases when using 6 eradication therapy (ET) regimens. SUBJECTS AND METHODS: The investigation enrolled a total of 231 patients who received anti-Helicobacter pylori therapy according to the intention-to-treat (ITT) principle, including 229 patients who met the protocol requirements, i.e. who completed the prescribed per-protocol (PP) treatment: 106 patients with duodenal bulb ulcer disease, 2 with gastric ulcer, 90 with erosive gastritis, and 31 patients with non-atrophic gastritis. In an outpatient setting, the patients received one of the 6 ET regimens: OAC, RBMA, RBCA, EBCA, sequential OACM therapy, and modified sequential OACMB therapy (O--omeprazole; A--amoxicillin; C--clarithromycin; B--bismuth tripotassium dicitrate, R--rabeprazole; M--metronidazole; E--esomeprazole). Treatment costs were calculated only from direct drug expenditures. The effective cost coefficient (K(eff)) was determined from the cost/ treatment efficiency ratio: K(eff) = cos/eff, where the cost was the average total costs; the eff was efficiency (%). RESULTS: The modified sequential OACMB therapy has proven to be more cost-efficient than the other regimens as it has a lower K(eff), (14). The RBMA regimens can overcome an 80% ET barrier (82.4%); however, in this case the K(eff) is 21.5. the sequential OACM therapy can also overcome an 80% ET barrier (84.8%); the K(eff) being 10.8. Incorporation of the bismuth preparation can achieve a more noticeable therapeutic effect up to 95.4%. The EBCA regimen has turned out to be most expensive with the highest K(eff) of 36.9. The RBCA regimen is most effective with the least K(eff) of 29; the therapeutic effect is 96.7%. CONCLUSION: The clinical cost-efficiency of ET is enhanced by the incorporation of the bismuth preparation for the treatment of patients with H. pylori-associated diseases. The modified sequential OACMB therapy can overcome resistance to clarithromycin and metronidazole with a good cost-efficiency.

Using stool antigen to screen for Helicobacter pylori in immigrants and refugees from high prevalence countries is relatively cost effective in reducing the burden of gastric cancer and peptic ulceration.

OBJECTIVES: Refugees and immigrants from developing countries settling in industrialised countries have a high prevalence of Helicobacter pylori (H. pylori). Screening these groups for H. pylori and use of eradication therapy to reduce the future burden of gastric cancer and peptic ulcer disease is not currently recommended in most countries. We investigated whether a screening and eradication approach would be cost effective in high prevalence populations. METHODS: Nine different screening and follow-up strategies for asymptomatic immigrants from high H. pylori prevalence areas were compared with the current approach of no screening. Cost effectiveness comparisons assumed population prevalence's of H. pylori of 25%, 50% or 75%. The main outcome measure was the net cost for each cancer prevented for each strategy. Total costs of each strategy and net costs including savings from reductions in ulcers and gastric cancer were also calculated. RESULTS: Stool antigen testing with repeat testing after treatment was the most cost effective approach relative to others, for each prevalence value. The net cost per cancer prevented with this strategy was US$111,800 (assuming 75% prevalence), $132,300 (50%) and $193,900 (25%). A test and treat strategy using stool antigen remained relatively cost effective, even when the prevalence was 25%. CONCLUSIONS: H. pylori screening and eradication can be an effective strategy for reducing rates of gastric cancer and peptic ulcers in high prevalence populations and our data suggest that use of stool antigen testing is the most cost effective approach.

Use of proton pump inhibitors for the provision of stress ulcer prophylaxis: clinical and economic consequences.

The provision of stress ulcer prophylaxis (SUP) for the prevention of clinically significant bleeding is widely recognized as a crucial component of care in critically ill patients. Nevertheless, SUP is often provided to non-critically ill patients despite a risk for clinically significant bleeding of roughly 0.1 %. The overuse of SUP therefore introduces added risks for adverse drug events and cost, with minimal expected benefit in clinical outcome. Historically, histamine-2-receptor antagonists (H2RAs) have been the preferred agent for SUP; however, recent data have revealed proton pump inhibitors (PPIs) as the most common modality (76 %). There are no high quality randomized controlled trials demonstrating superiority with PPIs compared with H2RAs for the prevention of clinically significant bleeding associated with stress ulcers. In contrast, PPIs have recently been linked to several adverse effects including Clostridium difficile diarrhea and pneumonia. These complications have substantial economic consequences and have a marked impact on the overall cost effectiveness of PPI therapy. Nevertheless, PPI use remains widespread in patients who are at both high and low risk for clinically significant bleeding. This article will describe the utilization of PPIs for SUP and present the clinical and economic consequences linked to their use/overuse.

Impact of clinical pharmacy services on stress ulcer prophylaxis prescribing and related cost in patients with renal insufficiency.

OBJECTIVES: Compared to the general population, chronic kidney disease patients are more vulnerable to gastrointestinal haemorrhage and its morbidity and mortality. Due to the fear of gastrointestinal bleeding consequences in these patients on the one hand, and the perception of general safety of acid suppressive medications on the other hand, inappropriate stress ulcer prophylaxis (SUP) seems to be encountered in nephrology wards. The objectives of this study were to evaluate appropriateness of acid suppression therapy in kidney disease patients and to assess the role of clinical pharmacists to decrease inappropriate SUP prescribing and related costs for these patients. METHODS: All inpatients at nephrology wards of a teaching hospital were assessed regarding appropriate SUP prescribing during a 6-month pre-intervention phase of the study without any clinical pharmacists' involvement in patients' management. Thereafter, during a 6-month post-intervention phase clinical pharmacists provided local SUP protocol and educational classes for physicians regarding appropriate SUP prescribing and participated actively in the patient-care team. MAIN FINDINGS: The results showed significant relative reduction in inappropriate SUP prescribing and related cost in patients with renal insufficiency by about 44% and 67% respectively. CONCLUSION: This study showed that implementing institutional guidelines, and active involvement of clinical pharmacists in the nephrology healthcare team, could reduce inappropriate SUP prescribing and related costs for these patients.

Cost-effectiveness analysis: stress ulcer bleeding prophylaxis with proton pump inhibitors, H2 receptor antagonists.

OBJECTIVES: Proton pump inhibitors (PPIs) and H2-receptor antagonists (H2RAs) present varying pharmacological efficacy in preventing stress ulcer bleeding (SUB) in intensive care units. The literature also reports disparate rates of ventilator-assisted pneumonia (VAP) as side effects of these treatments. We compared the cost-effectiveness of these two prophylactic pharmacological options. METHODS: We constructed a decision tree with a 60-day time horizon for patients at high risk for developing SUB, receiving either PPIs or H2RAs. For each treatment strategy, patients could be in one of three states of health: SUB, VAP, or no complication. Contemporary, clinically relevant probabilities were obtained from a broad literature search. Costs were estimated by using a representative US countrywide database. A third-party payer perspective was adopted. Cost-effectiveness and univariate and multivariate sensitivity analyses were performed. RESULTS: Probabilities of SUB and VAP were 1.3% and 10.3% for PPIs versus 6.6% and 10.3% for H2RAs, respectively. Lengths of stay and per diem costs were 24 days and US $2764 for SUB, 42 days and US $3310 for VAP, and 14 days and US $2993 for patients without complications. Average costs per no complication were US $58,700 for PPIs and US $63,920 for H2RAs. The H2RA strategy was dominated by PPIs. Sensitivity analysis showed that these findings were sensitive to VAP rates but PPIs remain cost-effective. The acceptability curve shows the stability of the probabilistic results according to varying willingness-to-pay values. CONCLUSION: PPI prophylaxis is the most efficient prophylactic strategy in patients at high risk of developing SUB when compared with using H2RAs.

Analysis of direct medical care costs of peptic ulcer disease in a Korean tertiary medical center.

OBJECTIVES: There have been no reported data on the medical care cost of idiopathic peptic ulcer disease (PUD) compared with H. pylori (+) and/or NSAID (+) cases although H. pylori-negative idiopathic ulcers are increasing. The aim of this study was to investigate the direct medical care costs of PUD based on whether it was H. pylori infection/from NSAIDs or idiopathic. MATERIAL AND METHODS: One hundred and seventy three patients with PUD comprising H. pylori and/or NSAID use-associated PUD (n = 145) and idiopathic PUD (n = 28) were prospectively enrolled in this study. The direct medical care costs were analyzed retrospectively for the patients with PUD during a one-year follow-up period. RESULTS: The recurrence rate within one year was significantly higher in idiopathic PUD than H. pylori and/or NSAID-associated PUD (p = 0.002). Direct medical care costs of idiopathic PUD ($2483.8) were higher than in patients with H. pylori and/or NSAID-associated PUD ($1751.8) resulting from longer duration of medication and higher proportion of endoscopic hemostasis and hospitalization. CONCLUSIONS: More clinical research is needed to improve outcome and reduce recurrence rate and medical care costs of idiopathic PUD.

Stress ulcer prophylaxis: reducing non-indicated prescribing after hospital discharge.

BACKGROUND: Gastric acid suppressant medications used as stress ulcer prophylaxis (SUP) in the intensive care unit (ICU) are often prescribed inappropriately after discharge. We present tools to reduce the use and cost of non-indicated SUP. OBJECTIVE: To reduce the non-indicated use of SUP after hospital discharge originally started in the ICU, using an education intervention and pharmacist-led medication reconciliation on patient care rounds and at hospital discharge. METHODS: In a retrospective medical record review using a historic control, 356 consecutively admitted patients to the medical/surgical ICU at the University of Wisconsin Hospital were assessed for the appropriate use of SUP at admission to the ICU, at transfer to a general care unit, and at hospital discharge. The education intervention involved teaching both the medical and pharmacist staff about indications for SUP using a memorandum and a pocket guide. Pharmacists also conducted medication reconciliation during daily patient care rounds and at discharge to justify medication use. The outcome of this study is the percentage of patients prescribed non-indicated gastric acid suppressants at hospital discharge. This outcome is compared to a previous study conducted at our hospital. RESULTS: Of 356 eligible patients, 308 (86.5%) received SUP while in the ICU. Thirty-nine (11%) were given continuing SUP after discharge from the hospital, of which 31 (8.7%) had no clear indication. This was a 64.3% reduction from the 24.4% found in the prior study (p < 0.0001). CONCLUSIONS: Educational materials that guide prescribing, pharmacist interaction on patient care rounds, and pharmacist-conducted medication reconciliation significantly reduced the prescribing of non-indicated gastric acid suppressant medications after hospital discharge.

Prevalencia de nueva hemorragia por úlcera péptica en pacientes tratados con inhibidores de la bomba de protones por vía intravenosa / Prevalence of rebleeding from peptic ulcer in patients treated with proton pump inhibitors

Fundamento y objetivo: El objetivo de este estudio es la evaluación de la prevalencia de resangrado por úlcera péptica comparando pacientes que habían recibido omeprazol frente a pantoprazol por vía intravenosa y estudiar los costes derivados de cada tratamiento. Pacientes y métodos: estudio observacional y retrospectivo. Se recogió información sobre el sexo y la edad de los pacientes, el diagnóstico de la hemorragia digestiva alta (HDA) según la clasificación de Forrest, el tipo de inhibidor de la bomba de protones (IBP) utilizado por vía intravenosa y la pauta de tratamiento, presencia o no de resangrado, mortalidad y datos referentes a los costes sanitarios mediante un modelo farmacoeconómico de coste-efectividad. Resultados: Se incluyó a 807 pacientes, 490 de los cuales (60,7%) recibieron pantoprazol y 317 (39,3%) omeprazol. No hubo diferencias entre la edad media de ambos grupos (61,2 frente a 62,3 años, p=0,544), sexo (el 71% de varones frente al 68,6% de mujeres; p=0,78), porcentaje de enfermos dentro del grado I de Forrest (el 35,1 frente al 42%; p=0,05), en el grado II (el 50,2 frente al 40,4%; p=0,006) y en el grado III (el 14,7 frente al 17,7%; p=0,259). El número de viales por día de tratamiento por vía intravenosa fue significativamente inferior en el grupo de pantoprazol desde el tercer al quinto día, sin diferencias en los dos primeros días y a partir del sexto. Hubo resangrado en el 8,2% de los pacientes tratados con pantoprazol y en el 11,7% de los tratados con omeprazol (p=0,098). Falleció el 2,2% de los pacientes tratados con pantoprazol frente al 2,6% de los tratados con omeprazol (p=0,086). El coste esperado de un paciente tratado con pantoprazol es de 2.188,25€ mientras que con omeprazol es de 3.279,02€ (p<0,001). Conclusiones: Si bien los resultados de la administración de omeprazol frente a pantoprazol por vía intravenosa en pacientes con HDA ulcerosa son similares, este último resulta tener mejor perfil de coste-efectividad (AU)

Background and objective: The aim of this study is to assess the prevalence of peptic ulcer rebleeding by comparing patients who received omeprazole versus pantoprazole i.v. as well as to study the costs of each treatment.Patients and methods: Retrospective and observational study. Information was gathered on sex and age of the patients, the diagnosis of upper gastrointestinal bleeding (UGB) according to the classification of Forrest, the type of proton pump inhibitor (PPI) i.v. used and the treatment regimen, presence or absence of rebleeding, mortality and data on health costs through a pharmacoeconomic cost-effectiveness analysis. Results: We included 807 patients, 490 of whom (60.7%) received pantoprazole and 317 (39.3%) omeprazole. There was no difference between the average age of both groups, 61.2 years vs 62.3, p=0.544; sex, 71% men vs 68.6%, P=.78; the percentage of patients within Forrest I was 35.1% vs 42%, P=.05, in grade II was 50.2% vs 40.4%, P=.006 and in grade III was 14.7% vs 17.7%, P=.259. The number of vials per day of treatment was significantly lower in the pantoprazole group from the third to fifth day, with no differences in the first two days and the sixth. There was rebleeding in 8.2% of patients treated with pantoprazole and 11.7% with omeprazole, P=.098. 2.2% of patients treated with pantoprazole died vs 2.6% treated with omeprazole, P=.086. The expected cost of a patient treated with pantoprazole was 2188.25€ vs 3279.02€ with omeprazole, P<.001. Conclusions: While the results of the administration of omeprazole vs pantoprazole i.v. in patients with UGB are similar, the latter turns out to have a better cost-effectiveness profile (AU)

Systematic review of the symptom burden, quality of life impairment and costs associated with peptic ulcer disease.

BACKGROUND: Management of peptic ulcer disease has improved over the past few decades. However, the widespread use of nonsteroidal anti-inflammatory drugs and low-dose acetylsalicylic acid means that the burden of peptic ulcer disease remains a relevant issue. METHODS: We systematically searched PubMed and EMBASE for articles published 1966-2007 that reported symptoms, impairment of well-being or health-related quality of life, and costs associated with peptic ulcer disease. RESULTS: Thirty studies reported the prevalence of patient-reported gastrointestinal symptoms in individuals with endoscopically diagnosed symptomatic peptic ulcer disease. Average prevalence estimates, weighted by sample size, were 81% (95% confidence interval [CI], 77%-85%) for abdominal pain (11 studies), 81% (95% CI, 76%-85%) for pain specifically of epigastric origin (14 studies), and 46% (95% CI, 42%-50%) for heartburn or acid regurgitation (11 studies). On average, 29% (95% CI, 25%-34%) of patients with peptic ulcer disease presented with bleeding, often as the initial symptom (11 studies). Patients with peptic ulcer disease had significantly lower health-related quality of life than the general population, as measured by the Psychological General Well-Being index (P <.05; 7 studies) and the Short-Form-36 questionnaire (P <.05; 2 studies). Direct medical costs of peptic ulcer disease based on national estimates from several countries were USD163-866 per patient. The most costly aspects of peptic ulcer disease management were hospitalization and medication. Complicated peptic ulcer disease is particularly costly, estimated to be USD1883-25,444 per patient. CONCLUSION: Peptic ulcer disease significantly impairs well-being and aspects of health-related quality of life, and is associated with high costs for employers and health care systems.
