Using an Improvement Model to Reduce Adverse Drug Events in VA Facilities

Potential Drug-Drug Interactions in Hospitalized Medical Patients: Data From Low Resource Settings

Introduction

Adverse events related to Drug-Drug Interactions (DDIs) are among the few common reasons for hospitalization worldwide; however, they can be prevented with an efficient patient-centered system. Different mechanisms have successfully limited the prevalence of DDIs in developed countries. There are limited data regarding DDIs from limited-resource settings. Furthermore, there is no cost-effective system that has shown promising results in preventing them in this setting. This study aims to assess the frequency of potential DDIs in a low-resource setting and to check its association with different factors such as poly-pharmacy and demographics.

Methods

Through this cross-sectional study, drug charts of patients admitted to a medical unit in November 2019 were analyzed using a structured questionnaire. A list of drugs co-prescribed to each patient was entered into the Medscape Drug Interaction checker to calculate the frequency and severity of potential DDIs.

Results

The mean age of patients was 49 years, and on average, seven drugs were prescribed to each patient. Among 100 analyzed prescriptions, 400 potential DDIs were identified with a mean of 4±5.42 per patient. According to Medscape interaction checker classification, 2 DDIs were contraindicated, 28 were serious, 246 required close monitoring, and 124 were minor. The most frequently encountered drug interaction was "spironolactone with furosemide." There was a significant correlation of the occurrence of potential DDIs with increased numbers of prescribed drugs.

Conclusion

Our patient population was prescribed more drugs per patient than calculated in other settings. Poly-pharmacy is an independent risk factor for DDIs. Lastly, advancing age exposes patients to poly-pharmacy, and therefore, they are at a higher risk of developing DDIs.

The economics of medicines optimization: policy developments, remaining challenges and research priorities

BACKGROUND

This review scopes the evidence on the effectiveness and cost-effectiveness of interventions to improve suboptimal use of medicines in order to determine the evidence gaps and help inform research priorities.

SOURCES OF DATA

Systematic searches of the National Health Service (NHS) Economic Evaluation Database, the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects.

AREAS OF AGREEMENT

The majority of the studies evaluated interventions to improve adherence, inappropriate prescribing and prescribing errors.

AREAS OF CONTROVERSY

Interventions tend to be specific to a particular stage of the pathway and/or to a particular disease and have mostly been evaluated for their effect on intermediate or process outcomes.

GROWING POINTS

Medicines optimization offers an opportunity to improve health outcomes and efficiency of healthcare.

AREAS TIMELY FOR DEVELOPING RESEARCH

The available evidence is insufficient to assess the effectiveness and cost-effectiveness of interventions to address suboptimal medicine use in the UK NHS. Decision modelling, evidence synthesis and elicitation have the potential to address the evidence gaps and help prioritize research.

What is the value and impact of quality and safety teams? A scoping review

BACKGROUND

The purpose of this study was to conduct a scoping review of the literature about the establishment and impact of quality and safety team initiatives in acute care.

METHODS

Studies were identified through electronic searches of Medline, Embase, CINAHL, PsycINFO, ABI Inform, Cochrane databases. Grey literature and bibliographies were also searched. Qualitative or quantitative studies that occurred in acute care, describing how quality and safety teams were established or implemented, the impact of teams, or the barriers and/or facilitators of teams were included. Two reviewers independently extracted data on study design, sample, interventions, and outcomes. Quality assessment of full text articles was done independently by two reviewers. Studies were categorized according to dimensions of quality.

RESULTS

Of 6,674 articles identified, 99 were included in the study. The heterogeneity of studies and results reported precluded quantitative data analyses. Findings revealed limited information about attributes of successful and unsuccessful team initiatives, barriers and facilitators to team initiatives, unique or combined contribution of selected interventions, or how to effectively establish these teams.

CONCLUSIONS

Not unlike systematic reviews of quality improvement collaboratives, this broad review revealed that while teams reported a number of positive results, there are many methodological issues. This study is unique in utilizing traditional quality assessment and more novel methods of quality assessment and reporting of results (SQUIRE) to appraise studies. Rigorous design, evaluation, and reporting of quality and safety team initiatives are required.

Extreme makeover: Transformation of the veterans health care system

The veterans health care system administered by the U.S. Department of Veterans Affairs (VA) was established after World War I to provide health care for veterans who suffered from conditions related to their military service. It has grown to be the nation's largest integrated health care system. As the system grew, a number of factors contributed to its becoming increasingly dysfunctional. By the mid-1990s, VA health care was widely criticized for providing fragmented and disjointed care of unpredictable and irregular quality, which was expensive, difficult to access, and insensitive to individual needs. Between 1995 and 1999, the VA health care system was reengineered, focusing especially on management accountability, care coordination, quality improvement, resource allocation, and information management. Numerous systemic changes were implemented, producing dramatically improved quality, service, and operational efficiency. VA health care is now considered among the best in America, and the VA transformation is viewed as a model for health care reform.

Improving safety and quality: how can education help?

National efforts to improve the quality and safety of health care present challenges for medical education and training. Today's doctors need to be skilled communicators who know how to identify, prevent and manage adverse events and near misses, how to use evidence and information, how to work safely in a team, how to practise ethically, and how to be workplace teachers and learners. These competencies (knowledge, skills and attitudes) are set out in the National Patient Safety Education Framework (NPSF) of the Australian Council for Safety and Quality in Health Care. The NPSF is designed to help medical schools, vocational colleges, health organisations and private practitioners develop curricula to enable health professionals to work safely. The NPSF describes what doctors (depending on their level of knowledge and experience) can do to demonstrate competencies in a range of quality and safety activities. Medical schools, vocational colleges, health organisations and private practitioners need to work collaboratively with one another and with other health professionals to ensure that patient safety and quality curricula are implemented and evaluated, and that valid and reliable assessments of learning outcomes are developed. Interdisciplinary and vertically integrated education and training are needed, incorporating innovative methods, to create a safer health care system.

Tort claims analysis in the Veterans Health Administration for quality improvement

Tort claims have been studied for various reasons. Several studies have found that most tort claims are not related to negligent adverse events and most negligent adverse events do not result in tort claims. Several studies have examined the disposition of tort claims to understand the likelihood of payment once a claim has been made. Still others have proposed that tort-claims trend analysis may help administrators target their quality-improvement efforts and identify problems with quality that would not otherwise be captured.

In this article, we conduct a tort-claims analysis to explore areas for quality improvement, specifically for patient safety, in the Veterans Health Administration (VHA). Patient safety is an increasingly highlighted aspect of health-care delivery. Failure to assure patient safety can result in bad clinical outcomes, additional costs of care, and a negative organizational image. Filing a tort claim is one way for an individual to express concern about an organization. For our analysis, we draw from resolved tort claims in the Veterans Health Administration from fiscal years 1989 to 2000.
