Sharing Lessons From Successes: Long-term Care Facilities That Weathered the Storm of COVID-19 and Staffing Crises.

PURPOSE: To identify leadership styles and staffing strategies in Missouri long-term care (LTC) facilities that stood out among their peers as "positive deviants" with regard to COVID-19 infections and staffing shortages. METHODS: Statewide survey of all LTC facilities to identify exemplar facilities with stable staffing and low rates of COVID-19. Interviews with senior leaders were conducted in 10 facilities in the state to understand the strategies employed that led to these "positive outliers." A result-based educational program was designed to describe their actions and staff reactions. RESULTS: Exemplar leaders used transformational leadership style. Top reasons for their success were as follows: (1) trusting and supportive staff relationships; (2) positive presence and communication; and (3) use of consistent staffing assignments. Strong statewide participation was noted in the educational programs.

An obesity paradox in patients with myocardial infarction undergoing percutaneous intervention.

BACKGROUND AND AIMS: Data concerning the relationship between body mass index (BMI) and outcome in myocardial infarction (MI) patients are inconclusive. Long-term data on the influence of BMI on survival in patients with MI who have undergone percutaneous intervention (PCI) are lacking. We aimed to assess the effect of different categories of BMI on long-term mortality. METHODS AND RESULTS: A single-center retrospective study of 6496 patients with MI who underwent PCI was performed. Patients were divided into six categories according to their BMI and these were compared. All-cause mortality was assessed over a median period of 6.0 years. An inverse J-shaped relationship was observed between BMI and long-term mortality. The lowest mortality was observed in patients with class I obesity. The patients with a BMI below 25.0 kg/m2 were more likely to die than patients with class I obesity. A gradual decrease in BMI below 25.0 kg/m2 was associated with a progressively increased risk of dying, with underweight patients showing a 2.18-fold increase in mortality risk. An obesity paradox was present. In addition, the patients with class III obesity had a more than 70% higher long-term mortality risk as compared to the reference group. Both lower and higher degrees of BMI were found to be harmful in patients with MI who underwent PCI. CONCLUSION: The obesity paradox was present in a very long-term follow-up of patients with MI who underwent PCI. However, both lower and higher BMI values are harmful, and an inverse J-shaped relationship between BMI and outcome was observed.

Enhancing sleep quality for nursing home residents with dementia: a pragmatic randomized controlled trial of an evidence-based frontline huddling program.

BACKGROUND: Disturbed sleep places older adults at higher risk for frailty, morbidity, and even mortality. Yet, nursing home routines frequently disturb residents' sleep through use of noise, light, or efforts to reduce incontinence. Nursing home residents with Alzheimer's disease and or related dementias-almost two-thirds of long-stay nursing home residents-are likely to be particularly affected by sleep disturbance. Addressing these issues, this study protocol implements an evidence-based intervention to improve sleep: a nursing home frontline staff huddling program known as LOCK. The LOCK program is derived from evidence supporting strengths-based learning, systematic observation, relationship-based teamwork, and efficiency. METHODS: This study protocol outlines a NIH Stage III, real-world hybrid efficacy-effectiveness pragmatic trial of the LOCK sleep intervention. Over two phases, in a total of 27 non-VA nursing homes from 3 corporations, the study will (1) refine the LOCK program to focus on sleep for residents with dementia, (2) test the impact of the LOCK sleep intervention for nursing home residents with dementia, and (3) evaluate the intervention's sustainability. Phase 1 (1 year; n = 3 nursing homes; 1 per corporation) will refine the intervention and train-the-trainer protocol and pilot-tests all study methods. Phase 2 (4 years; n = 24 nursing homes; 8 per corporation) will use the refined intervention to conduct a wedge-design randomized, controlled, clinical trial. Phase 2 results will measure the LOCK sleep intervention's impact on sleep (primary outcome) and on psychotropic medication use, pain and analgesic medication use, and activities of daily living decline (secondary outcomes). Findings will point to inter-facility variation in the program's implementation and sustainability. DISCUSSION: This is the first study to our knowledge that applies a dementia sleep intervention to systematically address known barriers to nursing home quality improvement efforts. This innovative study has future potential to address clinical issues beyond sleep (safety, infection control) and expand to other settings (assisted living, inpatient mental health). The study's strong team, careful consideration of design challenges, and resulting rigorous, pragmatic approach will ensure success of this promising intervention for nursing home residents with dementia.

Retention of a standard operating procedure under the influence of social stress and refresher training in a simulated process control task.

In a simulated process control task, we investigated the effects of refresher training and acute social stress on performing a standard operating procedure (SOP) containing a production and monitoring task and knowledge recall after a retention interval of two weeks. In a 2 × 2 between-group design (Factor 1: induced social stress, Factor 2: refresher training), 76 engineering students performed an SOP at t1 in week 1 and at t2 in week 3. A MANOVA in week three (t2) indicated a main effect of the refresher training for the SOP execution containing a production and a monitoring task and an impairing effect of stress on the monitoring task. That means that after a retention interval, stress mainly affects the SOP's monitoring task. An additional correlational analysis showed that knowledge test performance is negatively associated with cortisol level and that retentivity is a strong predictor for knowledge test performance and production task performance, too. Practitioner Summary: We investigated effects of social stress and refresher training on performing a standard operating procedure (SOP) after a retention interval of two weeks. The impact of social stress reduced the monitoring task performance as part of the SOP, but not the production outcome. Without refresher training, performance is significantly worse.

Does skill retention benefit from retentivity and symbolic rehearsal? - two studies with a simulated process control task.

Two experiments were designed to compare two symbolic rehearsal refresher interventions (imaginary practice, a hidden introspective process) and investigate the role of retentivity in skill retention. Retentivity is investigated as the ability to memorise and reproduce information and associations that were learned a short time ago. Both experiments comprised initial training (week 1), a symbolic rehearsal for the experimental group (week 2) and a retention assessment (week 3). In the first study, the experimental group received a symbolic rehearsal, while the control group received no rehearsal. In the second study, the experimental group received the same symbolic rehearsal used in study 1, enhanced with rehearsal tasks addressing human-computer interaction. The results showed that both symbolic rehearsal interventions were equally likely to mitigate skill decay. The retentivity showed medium to high correlations with skill retention in both studies, and the results suggest that subjects high in retentivity benefit more from a symbolic rehearsal refresher intervention. Practitioner Summary: Skill decay becomes a problem in situations in which jobs require the correct mastery of non-routine situations. Two experimental studies with simulated process control tasks showed that symbolic rehearsal and retentivity can significantly mitigate skill decay and that subjects higher in retentivity benefit more from refresher interventions.

Counteracting skill decay: four refresher interventions and their effect on skill and knowledge retention in a simulated process control task.

In process automation, skill decay has not been investigated systematically. In two experimental studies, refresher interventions (RIs) were compared to support skill and knowledge retention of a start-up procedure on a simulated process control task. Based on theories of proceduralisation, the 'testing-effect' and mental practice, four different RIs were designed. In Study 1 (N = 68), two experimental groups (EGs) received either an RI called 'Practice' or an RI called 'Skill Demonstration'. Both RIs support skill retention, but the Skill Demonstration-RI performed with a higher mental workload. In Study 2 (N = 68), two EGs received an RI called 'Symbolic Rehearsal' or an RI called 'Procedural Knowledge Test', and aimed at supporting knowledge retention. Both EGs supported knowledge retention but showed moderate skill decay. Results imply that RIs affect skill and knowledge retention differently and should be applied in accordance with the task requirements and their dependence on accurate skill or knowledge maintenance.

Time until incident dementia among Medicare beneficiaries using centrally acting or non-centrally acting ACE inhibitors.

BACKGROUND: Centrally active (CA) angiotensin-converting enzyme inhibitors (ACEIs) are able to cross the blood­brain barrier. Small observational studies and mouse models suggest that use of CA versus non-CA ACEIs is associated with a reduced incidence of Alzheimer's disease and related dementias (ADRD). OBJECTIVE: The aim of this research was to assess the effect of CA versus non-CA ACEI use on incident ADRD. DESIGN: This is a retrospective cohort study with a non-equivalent control group. SETTING AND PATIENTS" This study used a national random sample of Medicare beneficiaries enrolled in Part D with an ACEI prescription. A prevalent ACEI user cohort included beneficiaries (n = 107 179) with an ACEI prescription prior to 30 April 2007; beneficiaries without an ACEI prescription before this date were defined as incident ACEI users (n = 9840). MEASUREMENTS: The main outcome was time until first diagnosis of ADRD in Medicare claims. RESULTS: The unadjusted, propensity-matched and instrumental variable analyses of both the prevalent and incident ACEI user cohorts consistently showed similar time until incident ADRD in those taking CA ACEIs compared with those who took non-CA ACEIs. LIMITATIONS: The limitations of this study include the use of observational data, relatively short follow-up time and claims-based measure of cognitive decline. CONCLUSIONS: In this analysis of Medicare beneficiaries who were prevalent or incident users of ACEIs in 2007­2009, the use of CA ACEIs was unrelated to cognitive decline within 3 years of index prescription. Continued follow-up of these patients and more sensitive measures of cognitive decline are necessary to determine whether a cognitive benefit of CA ACEIs is realized in the long term.

Differential associations between body mass index and outcome in different age groups in patients with myocardial infarction.

OBJECTIVE: To investigate the association between age and body mass index (BMI) and mortality in patients with myocardial infarction (MI). Methods We divided 6453 patients into three age groups (<60, 60-75, >75 years) and five BMI categories. Thirty-day and long-term all-cause mortality were assessed. RESULTS: No association was found between the BMI category and 30-day mortality in any age group. The association between BMI and long-term multivariable-adjusted mortality risk was age-dependent. Overweight patients had a lower risk than patients with BMI <25 kg/m2 in all age groups (HR 0.62; 95%CI 0.45-0.85; p = 0.003, HR 0.78; 95%CI 0.65-0.93; p = 0.005, HR 0.82; 95%CI 0.70-0.95; p = 0.011 for ages <60, 60-75, >75 years, respectively). The lower risk of death as a function of BMI shifted upward with age, and the risk was also lower in patients with obesity grade I (HR 0.81; 95% CI 0.66-0.98; p = 0.035 and HR 0.78; 95% CI 0.63-0.97; p = 0.023 for ages 60-75, >75 years, respectively). Excessive obesity was harmful only in the oldest group. Patients with obesity grade III had more than a 2.5 times higher mortality risk than patients with BMI <25 kg/m2 only in this group (HR 2.58; 95%CI 1.27-5.24; p = 0.009). An obesity paradox was found in all age groups. CONCLUSION: Our results suggest that moderate weight gain with age improves long-term survival after MI and that the magnitude of this "protective" weight gain is greater in older compared to younger patients. However, excessive weight gain (obesity grade III) is particularly harmful in the oldest age group. The exact relationship between BMI, age, and mortality remains unclear.

Fat-Free Mass and Body Fat in Patients with Myocardial Infarction Who Underwent Percutaneous Coronary Intervention.

There are no data on the effects of fat-free mass (FFM) and body fat (BF) on prognosis in patients with myocardial infarction (MI). We investigated the effects of FFM and BF (which were estimated using formulas rather than direct measurements) on 30-day and long-term all-cause mortality in patients with MI who underwent percutaneous coronary intervention. We analyzed data from 6,453 patients with MI. The patients were divided into 2 categories (high/low) according to the fat-free mass index (FFMI) and 2 categories (low/high) according to the BF. The resultant 4 patient groups: HighFFMI-LowBF, HighFFMI-HighBF, LowFFMI-LowBF, and LowFFMI-HighBF, were compared. The lowest crude mortality after 30 days and in the long term was observed in the HighFFMI-LowBF group (3.0%,9.8%, respectively), followed by the HighFFMI-HighBF group (6.6%, 27.0%, respectively), the LowFFMI-LowBF group (10.4%, 36.0%, respectively), and the LowFFMI-HighBF group (14.7%, 56.8%, respectively). The difference was significant (p <0.0001), as was the difference between groups. After adjustment, the FFMI-BF groups independently predicted 30-day mortality (p = 0.003), but the risk was similar in all groups. Compared with the HighFFMI-LowBF group, the long-term mortality risk was similar in the HighFFMI-HighBF group (hazard ratio [HR] 1.11, 95% confidence interval [CI] 0.84 to 1.47, p = 0.47), but the LowFFMI-LowBF and LowFFMI-HighBF patients had a higher risk (HR 1.59, 95% CI 1.20 to 2.11, p = 0.001, HR 1.40, 95% CI 1.03 to 1.91, p = 0.033, respectively). Body composition predicted mortality better than body mass index in patients with MI. Mortality appeared to be inversely related to FFM, with patients with low FFM and low BF having a particularly high mortality risk. The body composition groups also confirmed the obesity paradox.

Virtual external implementation facilitation: successful methods for remotely engaging groups in quality improvement.

BACKGROUND: Relatively little guidance exists on how to use virtual implementation facilitation to successfully implement evidence-based practices and innovations into clinical programs. Yet virtual methods are increasingly common. They have potentially wider reach, emergent public health situations necessitate their use, and restrictions on resources can make them more attractive. We therefore outline a set of principles for virtual external implementation facilitation and a series of recommendations based on extensive experience successfully using virtual external implementation facilitation in a national program. MODEL AND RECOMMENDATIONS: Success in virtual external implementation facilitation may be achieved by facilitators applying three overarching principles: pilot everything, incorporate a model, and prioritize metacognition. Five practical principles also help: plan in advance, communicate in real time, build relationships, engage participants, and construct a virtual room for participants. We present eight concrete suggestions for enacting the practical principles: (1) assign key facilitation roles to facilitation team members to ensure the program runs smoothly; (2) create small cohorts of participants so they can have meaningful interactions; (3) provide clarity and structure for all participant interactions; (4) structure program content to ensure key points are described, reinforced, and practiced; (5) use visuals to supplement audio content; (6) build activities into the agenda that enable participants to immediately apply knowledge at their own sites, separate from the virtual experience; (7) create backup plans whenever possible; and (8) engage all participants in the program. These principles represent a novel conceptualization of virtual external implementation facilitation, giving structure to a process that has been, to date, inadequately described. The associated actions are demonstrably useful in supporting the principles and offer teams interested in virtual external implementation facilitation concrete methods by which to ensure success. Our examples stem from experiences in healthcare. But the principles can, in theory, be applied to virtual external implementation facilitation regardless of setting, as they and the associated actions are not setting specific.

Exit-site care in Austrian peritoneal dialysis centers -- a nationwide survey.

BACKGROUND: Catheter-associated infections markedly contribute to treatment failure in peritoneal dialysis (PD) patients. There is much controversy surrounding prophylactic strategies to prevent these infections. METHODS: In this nationwide multicenter study we analyzed strategies to prevent catheter-associated infections as performed in Austrian PD centers in 2006. A questionnaire was sent to all 23 PD centers in Austria. RESULTS: Ten different catheter models were used in the 332 patients being treated in the 23 Austrian PD centers. Systemic antibiotics prior to catheter placement were given by 17 of the 23 PD centers (glycopeptides, n = 7; cephalosporins, n = 10). Nasal swabs were taken preoperatively by 17 PD centers; nasal Staphylococcus aureus carriers were treated prophylactically with mupirocin cream in 15 of these centers. Dressing change was routinely performed in 318 of 332 chronic PD patients (nonocclusive film dressing, n = 58; gauze dressing, n = 260). Disinfectants for chronic exit-site care included povidone iodine (n = 155), sodium hypochlorite (n = 31), povidone iodine + sodium hypochlorite together (n = 102), and octenidine dihydrochloride/phenoxyethanol (n = 17). Water + non-disinfectant soap or 0.9% sodium chloride was administered as a cleansing agent to the exit site by 27 patients. Routine S. aureus screening (nasal and/or exit-site swabs) in chronic PD patients was performed in 12 PD centers; carriers were treated with mupirocin cream in 11 of these centers. Dialysis staff members were screened for S. aureus in 8 PD centers and spouses were screened for S. aureus in 5 PD centers. The overall exit-site infection rate was 1 episode/43.9 patient-months, tunnel infection rate was 1 episode/88.9 patient-months, and peritonitis rate was 1 episode/51.0 patient-months. Patients of centers that have installed a prophylaxis protocol for treating S. aureus carriers had lower mean infection rates compared with those not using such a protocol. CONCLUSION: Various individual prophylactic strategies are used to prevent catheter-associated infections in Austrian PD centers. Infection rates are within the range reported in the literature. There is still scope for improvement in some centers (e.g., by establishing a prophylaxis protocol).

Autoimmune disorders: gastrointestinal manifestations and endoscopic findings.

The gastrointestinal tract can be involved in many autoimmune disorders, and women are affected more than men in most of the disease processes discussed. As this article outlines, gastrointestinal manifestations can be either part of the clinical presentation or complications of treatment. Depending on the disease process and the severity of symptoms, gastrointestinal evaluation and treatment can have an important role in the management of these diseases.

Calculation of the diameter of the central retinal artery from noninvasive measurements in humans.

PURPOSE: The aim of the present study was to calculate the diameter of the central retinal artery from results as obtained with non-invasive techniques in healthy young subjects. METHODS: Twenty-four healthy male subjects participated in this study. Total retinal blood flow was calculated from combined bi-directional laser Doppler velocimetry and measurement of retinal venous diameters using the Zeiss retinal vessel analyzer. Using these techniques red blood cell velocity and vessel diameters of all visible veins entering the optic nerve head were measured and total retinal blood flow was calculated. Blood flow velocity in the central retinal artery was measured with color Doppler imaging. Form these outcome parameters the diameter of the central retinal artery was calculated for each subject individually. RESULTS: In the present study cohort the mean retinal blood flow was 38.1 +/- 9.1 microl/min and the mean flow velocity in the central retinal artery was 6.3 +/- 1.2 cm/s. From these data we calculated a mean diameter of the central retinal artery of 163 +/- 17 microm. CONCLUSIONS: Our results are in good agreement with data obtained from in vitro studies. The data of the present study also indicate that one needs to be careful to interpret velocity data from the central retinal artery in terms of retinal blood flow.
