Guideline Adherence in Dyspepsia Investigation and Treatment

Burden and Treatment of Chronic Upper GI Symptoms and Diagnoses: A Nationwide Study

BACKGROUND & AIMS

Chronic gastrointestinal (GI) symptoms are a common reason for seeking medical care. We aim to determine the rates of ambulatory care use and to characterize demographics, work-up, and treatment (pharmacologic and nonpharmacologic) for patients with chronic upper GI symptoms and conditions in the United States.

METHODS

Estimates of annual visits for the most common upper GI symptoms and diagnoses including gastroesophageal reflux disease, dyspepsia, nausea and vomiting, and gastroparesis were recorded from the 2007-2015 National Ambulatory Medical Care Surveys. Only chronic conditions, defined as >3 months, were included. We calculated the weighted proportion of ambulatory visits associated with pharmacologic, nonpharmacologic treatment (eg, diet, complementary and alternative medicine), or both.

RESULTS

A total of 116,184,475 weighted ambulatory visits were identified between the years of 2007 and 2015 for adults (average of 12,909,386 annual visits) with chronic upper GI symptoms and diagnoses. Gastroesophageal reflux disease was the most common reason for an ambulatory visit (n = 11,200,193), followed by dyspepsia (n = 1,232,598), nausea and vomiting (n = 714,834), and gastroparesis (n = 140,312). Pharmacologic treatment was more common than nonpharmacologic treatment (44.7% vs 28.5%). A total of 37.6% of patients were not receiving treatment at the time of the visit. These treatment patterns did not significantly change over the time of our study. Upper endoscopies were the most ordered test, representing 7.5% of all investigated upper GI symptoms.

CONCLUSIONS

Chronic upper GI symptoms and diagnoses account for a high number of annual health care visits, both in primary care and specialty care. Although there are several treatments, many of these patients are not on any treatments.

Up-Front Endoscopy Maximizes Cost-Effectiveness and Cost-Satisfaction in Uninvestigated Dyspepsia

BACKGROUND & AIMS

Practice guidelines promote a routine noninvasive, non-endoscopic initial approach to investigating dyspepsia without alarm features in young patients, yet many patients undergo prompt upper endoscopy. We aimed to assess tradeoffs among costs, patient satisfaction, and clinical outcomes to inform discrepancy between guidelines and practice.

METHODS

We constructed a decision-analytic model and performed cost-effectiveness/cost-satisfaction analysis over a 1-year time horizon on patients with uninvestigated dyspepsia without alarm features referred to gastroenterology. A RAND/UCLA expert panel informed model design. Four competing diagnostic/management strategies were evaluated: prompt endoscopy, testing for Helicobacter pylori and eradicating if present (test-and-treat), testing for H pylori and performing endoscopy if present (test-and-scope), and empiric acid suppression. Outcomes were derived from systematic reviews of clinical trials. Costs were informed by prospective observational cohort studies and national commercial/federal cost databases. Health gains were represented using quality-adjusted life years.

RESULTS

From the patient perspective, costs and outcomes were similar for all strategies (maximum out-of-pocket difference of $30 and <0.01 quality-adjusted life years gained/year regardless of strategy). Prompt endoscopy maximized cost-satisfaction and health system reimbursement. Test-and-scope maximized cost-effectiveness from insurer and patient perspectives. Results remained robust on multiple one-way sensitivity analyses on model inputs and across most willingness-to-pay thresholds.

CONCLUSIONS

Noninvasive management strategies appear to result in inferior cost-effectiveness and patient satisfaction outcomes compared with strategies promoting up-front endoscopy. Therefore, additional studies are needed to evaluate the drivers of patient satisfaction to facilitate inclusion in value-based healthcare transformation efforts.

Functional dyspepsia: a multifaceted problem in gastroenterology

The article presents the views on dyspepsia in world practice, data on the difficulties of diagnosis and the problem of the effectiveness of various therapy regimens. Particular attention is paid to the use of fixed forms of drugs for functional dyspepsia, in particular Omez DSR.

PARP inhibitors: clinical relevance and the role of multidisciplinary cancer teams on drug safety

INTRODUCTION

Cancer is considered one of the most devastating causes of death for humanity. Innovative and targeted therapies have become urgent in the treatment of this large subset of diseases. Over the last decade, the development of PARP (poly (ADP-Ribose) polymerase) inhibitors has emerged as a new target in cancer therapy.

AREAS COVERED

The authors conducted a review focusing on the clinic relevance and adverse effects of the four drugs already approved by drug regulatory agencies, namely: olaparib, rucaparib, niraparib and talazoparib. Despite the targeted action of this drug class, the adverse effects should be carefully monitored for the adequate safety of cancer patients taking them. The role of multidisciplinary cancer teams is crucial to help more and more patients to benefit from these revolutionary agents.

EXPERT OPINION

PARP (poly (ADP-Ribose) polymerase) inhibitors are drugs with great potential in the treatment of several types of cancer. However, their toxicity profiles often lead to treatment interruption or early discontinuation. The daily monitoring of these cancer patients by multidisciplinary cancer teams is essential for the success of therapy and for the promotion of a better quality of life.
