Exploring Perceptions of Health Care Providers' Use of Electronic Advance Directive Forms in Electronic Health Records.

The current study explored the perceptions of health care providers' use of electronic advance directive (AD) forms in the electronic health record (EHR). The Technology Acceptance Model (TAM) was used to guide the study. Of 165 surveys distributed, 151 participants (92%) responded. A moderately strong positive correlation was noted between perceived usefulness and actual system usage (r = 0.70, p < 0.0001). Perceived ease of use and actual system usage also had a moderately strong positive correlation (r = 0.70, p < 0.0001). In contrast, the strength of the relationship between behavioral intention to use and actual system usage was more modest (r = 0.22, p < 0.004). There was a statistically significant difference in actual system usage of electronic ADs across six departments (χ2[5] = 79.325, p < 0.001). The relationships among primary TAM constructs found in this research are largely consistent with previous TAM studies, with the exception of behavioral intention to use, which is slightly lower. These data suggest that health care providers' perceptions have great influence on the use of electronic ADs. [Journal of Gerontological Nursing, 45(1), 17-21.].

Levodopa as a possible treatment of visual loss in nonarteritic anterior ischemic optic neuropathy.

PURPOSE: To determine the clinical effectiveness and potential neuroprotection of levodopa in improving visual acuity, visual field, and retinal nerve fiber layer (RNFL) thickness in eyes affected by NAION. METHOD: Retrospective cohort study involving 59 eyes of 59 participants with NAION who were evaluated within 15 days of NAION onset. Participants received 25 mg carbidopa/100 mg levodopa three times daily with meals for 12 weeks (levodopa group) or were untreated (control group). Best-corrected visual acuity converted to logMAR, mean deviation (MD) threshold sensitivity on automated perimetry, and mean RNFL thickness on optical coherence tomography (OCT) were assessed. The primary outcome was the categorization of eyes into improved visual acuity (by 0.3 logMAR difference), worsened visual acuity (by 0.3 logMAR difference), or no change in visual acuity. The proportions in each category were compared between the levodopa and control groups. RESULTS: Among participants with 20/60 or worse initial visual acuity, levodopa-treated participants had significant improvement (P < 0.0001) in the mean change from initial to final logMAR visual acuity of -0.74 ± 0.56 (95 % CI, -0.98 to -0.50), while the mean change for the control group at -0.37 ± 1.09 (95 % confidence interval estimate, -1.00 to +0.26) was not significant (P = 0.23). A significant difference between groups was observed (P = 0.0086) such that 19/23 (83 %) in the levodopa group improved and none got worse, as compared with 6/14 (43 %) in the control group improving while four (29 %) worsened. The change in visual field MD and RNFL thickness on OCT showed no significant difference at P = 0.23 and P = 0.75 respectively. No levodopa-treated participant had any adverse event from the levodopa. CONCLUSIONS: Treatment within 15 days of onset of NAION with levodopa improved central visual acuity by an average of 6 lines on Snellen acuity chart. Levodopa may promote neuroprotection of the maculopapular retinal ganglion cell fibers in NAION.

Effects of Staffing and Regional Location on Influenza and Pneumococcal Vaccination Rates in Nursing Home Residents.

Vaccinations reduce the risk of hospitalizations and adverse health outcomes in older adult populations, which has led to initiatives such as the Healthy People 2010 goal to vaccinate 90% of all nursing home residents. The current analysis looked at the percentage of residents who received vaccinations in 15,653 nursing homes in the United States and relationships of vaccination to staffing intensity and regional location. Overall, approximately 75% of facilities reached the optimum 90% vaccination levels for long-term residents, but less than 50% reached this goal for short-term residents. Further analyses revealed a consistently lower median rate of vaccination for metropolitan areas and indicated a weak relationship between staffing levels of RNs and short-term resident vaccination. Factors influencing staffing levels, and the possible connection between vaccination and technology, are discussed, as well as suggestions for future research aimed at better understanding mechanisms involved in suboptimal influenza and pneumococcal vaccination in nursing homes.

Comparison of two portable lactate meters in dogs.

The objective of this study was to compare two portable lactate analyzers for testing canine patients in a clinical setting with a previously accepted methodology for measuring plasma lactate. Between Jan 1, 2005 and Jun 1, 2006, all samples were analyzed using two different portable analyzers (devices A and B), and 86 of those samples were also analyzed by a reference laboratory (REF). The concordance correlation coefficient (CCC) for device A and the REF was 0.949 (95% confidence interval [95% CI], 0.923-0.966). For device B and REF, the CCC was 0.990 (95% CI, 0.985-0.993). Only 8 of 85 samples (9.4%) exceeded a relative difference of 20% for device B (note that 1 of the 86 samples was not included because the lactate level fell below the detectable limit of device B), but 48 of 85 samples (56.5%) exceeded a relative difference of 20% for device A. Both portable lactate analyzers appeared to be effective in detecting clinically significant elevations in plasma lactate compared with the REF but device B had better agreement. A positive correlation among all three analyzers existed; however, the analyzers do not yield directly interchangeable results.

A Report of Information Technology and Health Deficiencies in U.S. Nursing Homes.

OBJECTIVE: The aim of the study was to investigate the impact of nursing home (NH) information technology (IT) sophistication on publically reported health safety deficiency scores documented during standard inspections. METHODS: The sample included 807 NHs from every U.S. state. A total of 2187 health inspections were documented in these facilities. A national IT sophistication survey describing IT capabilities, extent of IT use, and degree of IT integration in resident care, clinical support, and administrative activities in U.S. NHs was used. The relationship between NH health deficiencies and IT sophistication survey scores was examined, using weighted regression. RESULTS: Controlling for registered nurse hours per resident day, deficiency scores decreased as total IT sophistication increased. Controlling for total IT sophistication score, deficiency scores decreased as registered nurse hours per resident day increased. Ownership status significantly influenced health deficiency scores. CONCLUSIONS: These results highlight the necessity to understand benefits of implementing NH IT and demonstrating its impact on patient safety.

Pain management in nursing homes: what do quality measure scores tell us?

Pain management for older adults residing in nursing homes continues to present multifaceted challenges to health care practitioners and researchers. This study, which focuses on improvement in pain assessment and management, is a secondary analysis of data from a larger study, which used an intervention simultaneously directed at all levels of staff with change in quality measure (QM)/quality indicator (QI) scores to determine improvement in resident outcomes. We anticipated that focused improvement efforts in resident care regarding pain management would be reflected by correspondingly lower QM/QI scores over time. Findings of increased QM/QI scores may be positive in that they may point to increased attention by staff regarding pain management for residents.

Medication safety teams' guided implementation of electronic medication administration records in five nursing homes.

BACKGROUND: The 1.6 million nursing home residents in the United States are at high risk for adverse effects from medication errors. In an attempt to decrease medication errors and improve safety practices, from 2003 through 2007 the study investigators partnered with five Midwestern nursing homes in implementing electronic point-of-care medication administration records (eMARs) and focused quality improvement (QI) efforts. METHODS: The eMAR, designed by a vendor as a part of a larger integrated electronic health record, provided a point of information integration for a variety of users, including practitioners, nursing staff, medication administrators, and nursing home leadership. At each nursing home, a medication safety team guided the transition from traditional paper-based systems to the eMAR. RESULTS: The implementation and integration of the eMAR was monitored in more than 300 hours of detailed observation, resulting in nearly 16,000 medication doses across approximately 200 medication administrations (passes) for 3,700 residents. The types of medication errors most receptive to the combined impact of the eMAR and focused QI efforts were late and omitted (or missing) medications. DISCUSSION: Technology provided the structures and processes that improved communication and integrated complex processes. Yet, regardless of how effectively the technology was designed, it was "laid upon" nursing home medication administration systems that were archaic and fragmented. The implementation of technology could not solve chronic structure and process issues in isolation. However, using the technology to streamline processes, support effective decision making, integrate complex tasks, and bring real-time data to a medication safety team provided an effective mechanism to maximize the impact of technology and to minimize the unintended consequences of large-scale change.

Field testing, refinement, and psychometric evaluation of a new measure of quality of care for assisted living.

Field test results are reported for the Observable Indicators of Nursing Home Care Quality Instrument-Assisted Living Version, an instrument designed to measure the quality of care in assisted living facilities after a brief 30-minute walk-through. The OIQ-AL was tested in 207 assisted-living facilities in two states using classical test theory, generalizability theory, and exploratory factor analysis. The 34-item scale has a coherent six-factor structure that conceptually describes the multidimensional concept of care quality in assisted living. The six factors can be logically clustered into process (Homelike and Caring, 21 items) and structure (Access and Choice; Lighting; Plants and Pets; Outdoor Spaces) subscales and for a total quality score. Classical test theory results indicate most subscales and the total quality score from the OIQ-AL have acceptable interrater, test-retest, and strong internal consistency reliabilities. Generalizability theory analyses reveal that dependability of scores from the instrument are strong, particularly by including a second observer who conducts a site visit and independently completes an instrument, or by a single observer conducting two site visits and completing instruments during each visit. Scoring guidelines based on the total sample of observations (N = 358) help guide those who want to use the measure to interpret both subscale and total scores. Content validity was supported by two expert panels of people experienced in the assisted-living field, and a content validity index calculated for the first version of the scale is high (3.43 on a four-point scale). The OIQ-AL gives reliable and valid scores for researchers, and may be useful for consumers, providers, and others interested in measuring quality of care in assisted-living facilities.

Nursing home error and level of staff credentials.

Providing safe nursing home care is both a clinical and fiscal challenge in many countries. The fiscal realities result in the addition of other workers, such as medication technicians or aides (CMT/A), to the health care team. The purpose of this study was to determine the impact of various levels of credentialing among nursing home staff who deliver medications (RN, LPN, or CMT/A) on medication error. In addition, the impact of distractions and interruptions was explored. Using naïve observation, 39 medication administrators representing various levels of credentialing were unobtrusively observed to determine the number of medication errors, distractions, and interruptions in five nursing homes. There were no differences in medication error rates by level of credential. However, RNs had more interruptions during their medication administration, and these increased interruptions were associated with increased medication error rates when wrong time errors were excluded (p = .0348).

The State of Nursing Home Information Technology Sophistication in Rural and Nonrural US Markets.

OBJECTIVE: To test for significant differences in information technology sophistication (ITS) in US nursing homes (NH) based on location. METHODS: We administered a primary survey January 2014 to July 2015 to NH in each US state. The survey was cross-sectional and examined 3 dimensions (IT capabilities, extent of IT use, degree of IT integration) among 3 domains (resident care, clinical support, administrative activities) of ITS. ITS was broken down by NH location. Mean responses were compared across 4 NH categories (Metropolitan, Micropolitan, Small Town, and Rural) for all 9 ITS dimensions and domains. Least square means and Tukey's method were used for multiple comparisons. PRINCIPAL FINDINGS: Methods yielded 815/1,799 surveys (45% response rate). In every health care domain (resident care, clinical support, and administrative activities) statistical differences in facility ITS occurred in larger (metropolitan or micropolitan) and smaller (small town or rural) populated areas. CONCLUSIONS: This study represents the most current national assessment of NH IT since 2004. Historically, NH IT has been used solely for administrative activities and much less for resident care and clinical support. However, results are encouraging as ITS in other domains appears to be greater than previously imagined.

A national report of nursing home information technology: year 1 results.

OBJECTIVE: To provide a report on year 1 results of a national study investigating nursing home information technology (IT) adoption, called IT sophistication. METHODS: A reliable and valid survey was used to measure IT sophistication. The target goal was 10% from each state in the United States, 1570 nursing homes. A random sample of homes from each state was recruited from Nursing Home Compare. RESULTS: The team reached 2627 nursing home administrators, among whom 1799 administrators agreed to participate and were sent a survey. A total of 815 surveys were completed (45.3% response rate), which was below the goal. Facilities in the participating sample have similar demographic characteristics (ownership, total population in a location, and bed size) to the remaining homes not participating. There are greater IT capabilities in resident care and administrative activities, less in clinical support. The extent of use of these capabilities appears to be highest in administrative activities and lowest in clinical support. IT in resident care appears to be the most integrated with internal and external stakeholders. IT capabilities appear to be greater than IT extent of use in all health domains, with the greatest difference in resident care. DISCUSSION: National evaluations of nursing home IT are rare. Measuring trends in IT adoption in a nationally representative sample provides meaningful analytics that could be more useful for policy makers and nursing home leaders in the future. CONCLUSION: Discovering national baseline assessments is a first step toward recognizing nursing home trends in IT adoption.

Predictors of mortality for lower respiratory infections in nursing home residents with dementia were validated transnationally.

BACKGROUND AND OBJECTIVE: Generalizability of clinical predictors for mortality from lower respiratory infection (LRI) in nursing home residents has not been assessed for residents with dementia. STUDY DESIGN AND SETTING: In prospective cohort studies of LRI in 61 nursing homes in the Netherlands (n = 541) and 36 nursing homes in Missouri, USA (n = 564), we examined 14-day and 1- and 3-month mortality in residents with dementia who were treated with antibiotics. RESULTS: A logistic model predicting 14-day mortality derived from Dutch data included eating dependency, elevated pulse, decreased alertness, respiratory difficulty, insufficient fluid intake, high respiratory rate, male gender, and pressure sores. After adjusting coefficients with the heuristic shrinkage factor, the 14-day model showed good discrimination and calibration in both datasets. The apparent c-statistic for the original Dutch model was 0.80 (after correction for optimism, it was 0.75); the c-statistic was 0.74 in the U.S. validation population. The models predicting 1- and 3-month mortality showed moderate performance. A scoring system for estimating 14-day mortality performed equally well as the original model. CONCLUSION: We identified a set of credible clinical predictors that are easily assessed and demonstrated validity in identifying residents at low risk of dying from LRI across different nursing home populations. This tool should inform decision-making for families and doctors.

Changes in the use of postacute care during the initial Medicare payment reforms.

OBJECTIVE: To examine changes in postacute care (PAC) use during the initial Medicare payment reforms enacted by the Balanced Budget Act of 1997. DATA SOURCES: We used claims data from the 5 percent Medicare beneficiary sample in 1996, 1998, and 2000. Linked data from the Denominator file, Provider of Service file, and Area Resource File provided additional patient, hospital, and market-area characteristics. STUDY DESIGN: Six disease groups with high PAC use were selected for analysis. We used multinomial logit regression to examine how PAC use differed by year of service, controlling for patient, hospital, and market-area characteristics. PRINCIPAL FINDINGS: There were major changes in PAC use, and a portion of services shifted to settings where reimbursement remained cost-based. During the first reform, the home health agency interim payment system, home health use decreased consistently across disease groups. This decrease was accompanied by increased use in skilled nursing facilities (SNFs). Following the implementation of the prospective payment system for SNFs, the use of inpatient rehabilitation facilities increased. CONCLUSIONS: The shift in usage among settings occurred in two stages that corresponded to the timing of payment reforms for home health agencies and SNFs. Evidence strongly suggests the substitutability between PAC settings. Financial incentives, in addition to clinical needs and individual preferences, play a major role in PAC use.

Entrepreneurial program of research and service to improve nursing home care.

This is a methodological article intended to demonstrate the integration of multiple goals, multiple projects with diverse foci, and multiple funding sources to develop an entrepreneurial program of research and service to directly affect and improve the quality of care of older adults, particularly nursing home residents. Examples that illustrate how clinical ideas build on one another and how the research ideas and results build on one another are provided. Results from one study are applied to the next and are also applied to the development of service delivery initiatives to test results in the real world. Descriptions of the Quality Improvement Program for Missouri and the Aging in Place Project are detailed to illustrate real-world application of research to practice.

Field testing, refinement, and psychometric evaluation of a new measure of nursing home care quality.

The primary aim of this NINR-NIH-funded field test in 407 nursing homes in 3 states was to complete the development of and conduct psychometric testing for the Observable Indicators of Nursing Home Care Quality Instrument (Observable Indicators, OIQ). The development of the OIQ was based on extensive qualitative and iterative quantitative work that described nursing home care quality and did initial validity and reliability field testing of the instrument in 123 nursing homes in 1 state. The scale is meant for researchers, consumers, and regulators interested in directly observing and quickly evaluating (within 30 minutes of observation) the multiple dimensions of care quality in nursing homes. After extensive testing in this study, the Observable Indicators instrument has been reduced to 30 reliable and discriminating items that have a conceptually coherent hierarchical factor structure that describes nursing home care quality. Seven first-order factors group together into two second-order factors of Structure (includes Environment: Basics and Odors) and Process (includes Care Delivery, Grooming, Interpersonal Communication, Environment: Access, and Environment: Homelike) that are classic constructs of Quality, which was the third-order factor. Internal consistency reliability for the 7 first-order factors ranged from .77 to .93. Construct validity analyses revealed an association between survey citations and every subscale as well as the total score of the OIQ instrument. Known groups analysis revealed expected trends in the OIQ scores. The Observable Indicators instrument as a whole shows acceptable interrater and test-retest reliabilities, and strong internal consistency. Scale subscales show acceptable reliability as well. Generalizability Theory analyses revealed that dependability of scores can be improved by including a second site observer, or by revisiting a site. There is a small additional benefit from increasing observers or visits beyond two.

Improving care at lower cost for end-stage heart and lung disease: integrating end of life planning with home care.

Patients with advanced heart and lung disease experience exacerbations resulting in hospitalizations and interventions the patient may not desire. Strategies are needed that address end of life issues, honor preferences, and improve care without increasing cost. This study examines the impact on hospitalization and care cost of an integrated system of end of life care and interdisciplinary home care for mid-Missouri veterans with advanced congestive heart failure or chronic obstructive pulmonary disease.

Effects of repeated gas sterilization on closure rates of ameroid ring constrictors in vitro.

OBJECTIVE: To determine the effect of repeated gas sterilization on rate of closure of ameroid ring constrictors in vitro. SAMPLE: Twenty-four 3.5-mm ameroid ring constrictors. PROCEDURES: Ameroid ring constrictors were allocated to 1 of 4 treatment groups (6/group) to undergo gas sterilization 0, 1, 5, or 10 times. After sterilization, constrictors were incubated in canine plasma at a protein concentration of 3 g/dL for 27 days. A digital camera was used to obtain images of the constrictors prior to and at various points during incubation, and lumen diameter was measured. RESULTS: Mean ± SD percentage of lumen closure for all groups of ameroid ring constrictors combined was 85.2 ± 1.6% at day 0 (prior to plasma incubation) and 95.4 ± 0.8% at day 27. Mean lumen area was 3.64 ± 0.43 mm(2) (95% confidence interval, 2.67 to 4.77 mm(2)) at day 0 and 1.32 ± 0.25 mm(2) (95% confidence interval, 0.76 to 2.04 mm(2)) at day 27. None of the ameroid ring constrictors had closed completely by day 27. CONCLUSIONS AND CLINICAL RELEVANCE: Overall closure rates for ameroid ring constrictors appeared to be unaffected by repeated gas sterilization up to 10 times. Findings suggested that veterinary surgeons can resterilize ameroid ring constrictors up to 10 times with confidence that ring properties would remain suitable for clinical use.

Antibiotic treatment and survival of nursing home patients with lower respiratory tract infection: a cross-national analysis.

PURPOSE: Although lower respiratory tract infections are a leading cause of death in frail elderly patients, few studies have compared treatments and outcomes. We assessed the effects of different antibiotic treatment strategies on survival of elderly nursing home residents with lower respiratory tract infections in the United States and the Netherlands, where treatment approaches are quite different. METHODS: We combined data from 2 prospective cohort studies of lower respiratory tract infections conducted in 36 nursing homes in the United States and 61 in the Netherlands. We included residents whose infections were treated with antibiotics: 806 in the United States and 415 in the Netherlands. Outcome measures were 1-month and 3-month mortality. We used logistic regression to adjust for differing illness severity. RESULTS: Dutch residents had higher mortality than US residents (28.1% vs 15.1% at 1 month, respectively; P <.001). After adjusting for illness severity with logistic regression, the differences between the Dutch and US populations were not significant (odds ratio 1.34; 95% confidence interval, 0.94-1.90). Predicted mortality was overestimated for more severely ill US residents at 1 month but not at 3 months. No antibiotic regimen was consistently associated with increased or decreased mortality. CONCLUSION: Despite differences in illness severity and treatment, adjusted mortality did not differ between the 2 countries. Although we cannot exclude a short-term survival benefit from more aggressive treatment in the United States, differences in baseline health appear prognostically more important than the type of antibiotic treatment.
