ABSTRACT

The dynamin-related guanosine triphosphatase, Drp1 (encoded by Dnm1l), plays a central role in mitochondrial fission and is requisite for numerous cellular processes; however, its role in muscle metabolism remains unclear. Here, we show that, among human tissues, the highest number of gene correlations with DNM1L is in skeletal muscle. Knockdown of Drp1 (Drp1-KD) promoted mitochondrial hyperfusion in the muscle of male mice. Reduced fatty acid oxidation and impaired insulin action along with increased muscle succinate was observed in Drp1-KD muscle. Muscle Drp1-KD reduced complex II assembly and activity as a consequence of diminished mitochondrial translocation of succinate dehydrogenase assembly factor 2 (Sdhaf2). Restoration of Sdhaf2 normalized complex II activity, lipid oxidation, and insulin action in Drp1-KD myocytes. Drp1 is critical in maintaining mitochondrial complex II assembly, lipid oxidation, and insulin sensitivity, suggesting a mechanistic link between mitochondrial morphology and skeletal muscle metabolism, which is clinically relevant in combatting metabolic-related diseases.

ABSTRACT

BACKGROUND: The Centers for Disease Control and Prevention identifies Clostridioides difficile infection (CDI) as an urgent threat to people and health care systems. CDI leads to high health care utilizations and results in significantly reduced quality of life for patients. The high burden of disease is seen across all health care settings, outside of the hospital, in the community, and in younger people. Individuals with CDI transition from hospitals to long-term care facilities to the community, and management of these transitions can reduce the incidence of recurrence and rehospitalization. PURPOSE: The most common cause of diarrhea occurring in a health care setting is Clostridioides difficile and is also the cause of antibiotic-associated colitis (L. C. McDonald, 2021). The infection results from a disruption in the microbial flora of the gastrointestinal tract, mostly after antibiotic use or other medications such as proton pump inhibitors (PPIs). As a result, infected individuals are colonized and shed the spores into the environment, exposing others-goals of treatment focus on reducing the exposure and individual susceptibility. Although the incidence of C. diff is stable, recurrence is increasing significantly, with severe complications also a concern. The increased incidence and potential for life-threatening conditions require reducing initial exposure, supporting prescribed treatment, and preventing recurrence. PRIMARY PRACTICE SETTINGS: C. diff infection can be contracted in health care facilities and in the community. Case managers from nearly all practice settings may encounter patients with the infection. FINDINGS/CONCLUSIONS: To avert the devastating complications of Clostridioides difficile infection, case managers play an essential role in the prevention of recurrence with education, advocacy of best practices, effective care coordination, and thorough transitions of care. Each recurrence of C. diff infection leaves the patient vulnerable to the potential for surgical intervention, sepsis, and death. IMPLICATIONS FOR CASE MANAGEMENT: Mitigating the risk for readmission and recurrence will enhance C. diff infection care, safety, and outcomes to improve a patient's health care journey and quality of life. Case managers need to take a primary role in the transition and care coordination processes, including patient and support system education, coordination of any postdischarge services, connection to providers, adherence support activities, and follow-up for improvement or changes in condition. Supportive adherence activities and prevention education can result in the avoidance of recurrence. Case managers are well-equipped to locate resources to assist those patients challenged with the cost of medications, inability to attend appointments, or access basic needs. Although not directly related to C. diff, these challenges contribute to recurrence and readmission. Mitigating risk for readmission and recurrence results in an improved quality of life.

ABSTRACT

OBJECTIVES: The aim of the study was to investigate the efficacy of intravenous (IV) smart pumps with drug libraries and dose error reduction system (DERS) to intercept programming errors entailing high risk for patients in an adult intensive care unit (ICU). METHODS: A 2-year retrospective study was conducted in the adult ICU of the Hospital Juárez de México in Mexico City to evaluate the impact of IV smart pump/DERS (Hospira MedNet) technology implementation. We conducted a descriptive analysis of the reports generated by the system's software from April 2014 through May 2016. Our study focused on the upper hard limit alerts and used the systems' variance reports and IV Medication Harm Index methodology to determine the severity of the averted overdoses for medications with the highest number of edits. RESULTS: The system monitored 124,229 infusion programs and averted on 36,942 deviations of the preset safe limits. Upper hard limit alerts accounted for 26.4% of pump reprogramming events. One hundred sixty-six significant administration errors were intercepted and prevented, and IV Medication Harm Index analysis identified 83 of them as highest-risk averted overdoses with insulin accounting for 51.8% of those. The rate of compliance with the safety software during the study period was 69.8%. CONCLUSIONS: Our study contributes additional evidence of the impact of IV smart pump/DERS technology. These pumps effectively intercepted severe infusion errors and significantly prevented adverse drug events related to dosing. Our results support the implementation of this technology in ICUs as a minimum safety standard and could help drive an IV infusion safety initiative in Mexico.

ABSTRACT

Background: The use of smart pump technology has shown to be profitable in the intensive care unit (ICU) because it avoids costs from prevented medication errors and allows for savings on disposables and medications by establishing standardized concentrations and dosing units. Objective: The objective of the study is to evaluate the economic impact of the implementation of smart infusion pumps in the consumption of intravenous (IV) solutions in an ICU. Methods: A retrospective observational study was conducted with a pre-post design. The study occurred in the adult ICU of the Hospital Juárez de México. The pattern of consumption of IV solutions (sodium chloride 9%, Hartmann's solution, dextrose 5% and 10%, sodium chloride 0.9% with dextrose 5%) was analyzed preimplementation and postimplementation of 50 Plum A+™ pumps with Hospira MedNet™ security software. Using the TreeAge Pro 2016 software, deterministic and probabilistic analyses were carried out (10 000 Monte Carlo simulations) to confirm the robustness of the annual consumption comparison and the associated expenses before and after implementing smart technology. Results: The implementation of the smart pumps reduced the annual consumption of IV solutions to 8994 units (18%) and 3649 liters (22.3%). In the first year, MXN$55 850.97 were saved. From an institutional perspective and with a probability of 0.63, the use of MedNet™ technology proved to be a lower cost alternative (17.1% saved) with respect to the conventional infusion systems. Conclusion: The implementation of smart infusion pumps allows savings, specifically for the IV solutions used in ICU.

ABSTRACT

OBJECTIVE: This article describes an innovative integrated approach to case management using a standardized complexity assessment grid and communication tool, which is designed to identify barriers to improvement in 4 domains: biological, psychological, social, and health system; to create and implement holistic care plans based on "anchored barriers; and to document ongoing targeted outcomes. PRACTICE SETTINGS: Adult and pediatric case and disease managers working for hospitals or clinics, health care delivery systems, general medical health plans, care management vendors, government agencies, and employers can effectively employ integrated case management procedures. INTEGRATED CASE MANAGEMENT: Integrated case management augments traditional care coordination by allowing trained medical or mental health managers to assist with cross-disciplinary barriers without handoffs; to connect multidomain barriers to mutually agreed-upon care plan goals and activities; and to measure clinical, functional, fiscal, quality of life, and satisfaction outcomes as a part of the management process, especially in high-cost, complex patients. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Integrated case management provides a step-by-step interdisciplinary approach for helping complex patients that has the potential to maximize clinical and functional value, while reducing total health-related costs.

ABSTRACT

The 5% of patients using 50% of health resources commonly have interacting and persistent multimorbid illnesses; concurrent mental health problems; impaired social networks; and/or difficulties in accessing care through the health system. To improve outcomes in these patients, it is necessary to overcome clinical and nonclinical barriers that lead to poor health, treatment resistance, high health care cost, and disability. This article describes an innovative complexity-based and outcome-oriented approach using integrated case management. It helps treating physicians and health administrators understand how to incorporate value-based case managers to optimize care for complex patients while better utilizing resources.
