Increasing Access to Diabetes Care in Underserved Populations Using Mobile Medicine: How Point-of-Care Testing on Mobile Clinics Strengthens Hemoglobin A1c Adherence in Vulnerable and Underserved Populations.

BACKGROUND: The Center for Disease Control and Prevention (CDC) reported 26.9 million individuals a diabetes diagnosis rate of 9.4% in the United States had diabetes in 2018, equivalent to 8.2% of the population (CDC, 2020). Key government organizations have developed clinical quality indicators (CQIs) to ensure patients receive adequate care. The CQIs for comprehensive diabetes care are complex and often indicate a gap-in-care among vulnerable populations. OBJECTIVE: To evaluate if the availability of point-of-care (POC) hemoglobin A1c (HbA1c) testing in a mobile clinic increases CQIs adherence in vulnerable populations. METHODS: This evidence-based clinical practice change project (EBCPCP) focused on improving diabetic CQIs in vulnerable populations by implementing POC HbA1c testing on a federally qualified health centers (FQHC) mobile clinic. RESULTS: The results, 125 individuals having received HbA1c results, indicate having POC HgbA1c testing available on the mobile unit increased HbA1c testing. No patients had an HbA1c lab completed prior to the availability of POC testing. CONCLUSION: The availability of POC testing on a mobile clinic increases access to HbA1c for vulnerable populations which improves practice outcomes and increased CQI adherence. IMPLICATIONS FOR NURSING: The results of this EBCPCP indicate POC testing increases access to diagnostics and care.

Identifying pitfalls in chest tube insertion: improving teaching and performance.

OBJECTIVE: Chest tube thoracostomies are common surgical procedures, but little is known about how practitioners learn the skill. This study evaluates the frequency with which correctly performed tasks are executed by subjects during chest tube thoracostomies. DESIGN: In this prospective study, we developed a mobile-learning module, containing stepwise multimedia guidance on chest tube insertion. Next, we developed and tested a 14-item checklist, modeled after key skills in the module. Participants, defined as "novice" (fewer than 10 chest tubes placed) or "expert" (10 or more placed), were assigned to either the video or control group. A trained clinician used the checklist to rate participants while they inserted a chest tube on a TraumaMan simulator. SETTING: University of Miami, Miller School of Medicine, a tertiary care academic institution. PARTICIPANTS: Current medical students, residents, and the United States Army Forward Surgical Team members rotating through the institution. One hundred twenty-eight subjects entered and finished the study. RESULTS: One hundred twenty-eight subjects enrolled in the study; 86 (67%) were residents or US Army Forward Surgical Team members, 66 (77%) were novices, and 20 (23%) were experts. Novices most frequently connected the tube to suction (91%), adequately dissected the soft tissue (82%), and scrubbed or anesthetized appropriately (80%). They least frequently completed full finger sweeps (33%), avoided the neurovascular bundle (35%), and performed a controlled pleural puncture (39%). Comparing the novice video group with the novice control group, the video group was more likely to correctly perform a finger sweep (42%, p<0.001) and clamp the distal end of the chest tube (42%, p<0.001). Of all the steps, experts least frequently completed full finger sweeps (70%) and avoided the neurovascular bundle (75%). Comparing the expert video group with the expert control group, the video group was more likely to correctly perform finger sweeps, the incision, and clamping the distal chest tube (20%, p = not significant). CONCLUSIONS: Avoiding the neurovascular bundle, controlled pleural entry, and finger sweeps are most often performed incorrectly among novices. This information can help instructors to emphasize key didactic steps, possibly easing trainees' learning curve.

Knowledge and usability of a trauma training system for general surgery residents.

BACKGROUND: Resident work-hour restrictions challenge educators to supplement residents' surgical education. We evaluated a computer-based trauma surgery system's ability to increase residents' surgical knowledge. METHODS: Modules on thoracic and abdominal surgical approaches were evaluated. Surgical residents with 1 or more years of experience completed the pretest, an interactive module, the post-test, and a usability survey. RESULTS: Fifteen participants completed both modules. Thoracic module pretest and post-test scores were 56 ± 11 (mean ± standard deviation) and 90 ± 10, respectively (P < .0001). Mean abdominal module scores were 48 ± 20 and 85 ± 14, respectively (P < .0001). The usability survey showed that 87% of participants would use these modules to supplement their trauma training, 93% could easily distinguish anatomic detail, and 100% thought that procedures were shown clearly. CONCLUSIONS: This novel computer-based trauma education training system improved residents' knowledge of anatomy, surgical incisions, exposures, and technique. As innovative didactic tools arise in postgraduate medical education, it is crucial to document their effects on educational processes, learning satisfaction, and knowledge outcomes.

Mobile learning module improves knowledge of medical shock for forward surgical team members.

OBJECTIVE: Acute trauma care is characterized by dynamic situations that require adequate preparation to ensure success for military health professionals. The use of mobile learning in this environment can provide a solution that standardizes education and replaces traditional didactic lectures. METHODS: A comparative evaluation with a pre-post test design regarding medical shock was delivered via either a didactic lecture or a mobile learning video module to U.S. Army Forward Surgical Team (FST) members. Participants completed a pretest, were randomly assigned to treatment group by FST, and then completed the post-test and scenario assessment. RESULTS: One-hundred and thirteen FST members participated with 53 in the mobile learning group and 60 in the lecture group (control). The percent mean score for the mobile learning group increased from 43.6 to 70 from pretest to post-test, with a scenario mean score of M = 56.2. The percent mean score for the control group increased from 41.5 to 72.5, with a scenario mean score of M = 59.7. The two-way analysis of variance mean score difference was 26.4 for the mobile learning group and 31.0 for the control, F = 2.18, (p = 0.14). CONCLUSIONS: Mobile learning modules, coupled with a structured assessment, have the potential to improve educational experiences in civilian and military settings.

Effectiveness of stepwise interventions targeted to decrease central catheter-associated bloodstream infections.

OBJECTIVE: Determine the impact of three stepwise interventions on the rate of central catheter-associated bloodstream infections. DESIGN: Quasi-experimental study. SETTING: Three surgical intensive care units (general surgery, trauma, and neurosurgery) at a 1500-bed county teaching hospital in the Miami metro area. PATIENTS: All consecutive central catheter-associated bloodstream infection cases as determined by the Infection Control Department. INTERVENTIONS: Three interventions aimed at catheter maintenance were implemented at different times in the units: chlorhexidine "scrub-the-hub," chlorhexidine daily baths, and daily nursing rounds aimed at assuring compliance with an intensive care unit goal-oriented checklist. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the monthly intensive care unit rate of central catheter-associated bloodstream infections (infections per 1000 central catheter days). Over 33 months of follow-up (July 2008 to March 2011), we found decreased rates in each of the three intensive care units evaluated during the interventions, especially after implementation of chlorhexidine daily baths. Rates in unit A decreased from a rate of 8.6 to 0.5, unit B from 6.9 to 1.6, and unit C from 7.8 to 0.6. Secondary bloodstream infection rates remained unchanged throughout the observation period in units A and B; however, unit C had a decrease in its rates over time. CONCLUSIONS: We report the progressive reduction of central catheter-associated bloodstream infection rates after the stepwise implementation of chlorhexidine "scrub-the-hub" and daily baths in surgical intensive care units, suggesting effectiveness of these interventions.

Use of mobile learning module improves skills in chest tube insertion.

BACKGROUND: Just-In-Time Learning is a concept increasingly applied to medical education, and its efficacy must be evaluated. MATERIALS AND METHODS: A 3-minute video on chest tube insertion was produced. Consenting participants were assigned to either the video group, which viewed the video on an Apple® iPod Touch immediately before chest tube insertion, or the control group, which received no instruction. Every participant filled out a questionnaire regarding prior chest tube experience. A trained clinician observed participants insert a chest tube on the TraumaMan® task simulator, and assessed performance using a 14-item skills checklist. RESULTS: Overall, 128 healthcare trainees participated, with 50% in the video group. Participants included residents (34.4%, n = 44), medical students (32.8%, n = 42), and U.S. Army Forward Surgical Team members (32.8%, n = 42). Sixty-nine percent of all participants responded that they had never placed a chest tube, but 7% had placed more than 20. Only 25% of the participants had previously used TraumaMan®. Subjects who viewed the video scored better on the skills checklist than the control group (11.09 ± 3.09 versus 7.17 ± 3.56, P < 0.001, Cohen's D = 1.16). Medical students (9.33 ± 2.65 versus 4.52 ± 3.64, P < 0.001), Forward Surgical Team members (10.07 ± 2.52 versus 8.57 ± 3.22, P < 0.001), anesthesia residents (8.25 ± 2.56 versus 5.9 ± 2.23, P = 0.017), and subjects who had placed fewer than 10 chest tubes (9.7 ± 3 versus 6.6 ± 3.9, P < 0.001) performed significantly better with the video. CONCLUSIONS: The procedural animation video is an effective medium for teaching procedural skills. Embedding the video on a mobile device, and allowing trainees to access it immediately before chest tube insertion, may enhance and standardize surgical education for civilians and military personnel.

Successful eradication of a monoclonal strain of Klebsiella pneumoniae during a K. pneumoniae carbapenemase-producing K. pneumoniae outbreak in a surgical intensive care unit in Miami, Florida.

We describe the investigation and control of a Klebsiella pneumoniae carbapenemase-producing K. pneumoniae outbreak in a 20-bed surgical intensive care unit during the period from January 1, 2009 through January 1, 2010. Nine patients were either colonized or infected with a monoclonal strain of K. pneumoniae. The implementation of a bundle of interventions on July 2009 successfully controlled the further horizontal spread of this organism.
