Adherence to Best Practice Advice for Diagnosis of Pulmonary Embolism.

PURPOSE: This study evaluated clinician adherence to the American College of Physicians Best Practice Advice for diagnosis of pulmonary embolism. DESIGN: A prospective, single-center, descriptive design was utilized. METHODS: A heterogeneous sample of 111 hemodynamically stable adult inpatients with a computed tomography pulmonary angiogram ordered was consented. Electronic medical records were reviewed for demographic and clinical variables to determine adherence. The 6 individual best practice statements and the overall adherence were evaluated by taking the sum of "yes" answers divided by the sample size. RESULTS: Overall adherence was 0%. Partial adherence was observed with clinician-recorded clinical decisions rules and obtaining d-dimer (3.6% [4/111] and 10.2% [9/88], respectively) of low/intermediate probability scorers. Age adjustment of d-dimer was not recorded. Computed tomography pulmonary angiogram was the first diagnostic test in 89.7% (79/88) in low/intermediate probability patients. CONCLUSION: In hemodynamically stable, hospitalized adults, adherence to best practice guidelines for diagnosis of pulmonary embolism was minimal. Clinical utility of the guidelines in hospitalized adults needs further evaluation. Systems problems (eg, lack of standardized orders, age-adjusted d-dimer values, information technology support) likely contributed to poor guideline adherence.

Foot Care Self-Management in Non-Diabetic Older Adults: A Pilot Controlled Trial.

Self-management can mitigate common foot problems; however, community-dwelling older adults without diabetes rarely receive foot care self-management training. This two-group pilot study examined feasibility and preliminary efficacy of the novel, nurse-led 2 Feet 4 Life intervention. Twenty-nine adults (M age 76 years ± 6.6 years) from two senior centers completed the study (90.6% retention rate). Intervention dosage was one hour/week for four consecutive weeks. Study procedures were safe and feasible. Intervention group participants found the intervention acceptable and valuable. Observed between-group effect sizes were the following: knowledge (4.339), self-efficacy (3.652), behaviors (3.403), pain (0.375) and foot health (0.376). Large effect sizes were observed within-groups and within their interaction for knowledge (1.316), behaviors (8.430), pain (9.796), and foot health (3.778). Effect sizes suggest the intervention impacted foot care outcomes between groups and within individuals over seven months' time. Fully powered studies are indicated to test the intervention in diverse samples with more complex foot problems.

Foot Health Assessment and Problem Identification in a Dominican Batey Community: A Descriptive Study.

PURPOSE: Foot problems can adversely impact foot function and quality of life. Foot problems are often overlooked, particularly in populations with limited health care access. Little is known about the foot health of Haitian immigrants who live and work in the bateyes (rural sugarcane villages) of the Dominican Republic. These immigrant workers may experience foot problems that could affect foot function and the ability to work and provide for their families. DESIGN: Cross-sectional, exploratory, descriptive study design. SUBJECTS AND SETTING: A convenience sample of adults was recruited from an ongoing community-based participatory research project evaluating a mobile hypertension screening and treatment clinic program in 11 Dominican batey communities. METHODS: Foot health was assessed using the Foot Problems Checklist, a 24-item survey instrument developed for this study based on a review of the literature and foot clinician expertise. A certified foot care nurse recorded foot health data on the Foot Problems Checklist via visual and physical inspection. RESULTS: Study participants were 25 females and 16 males, aged 18 to 90 years, and all had at least one foot health problem. The most common foot problems were calluses (78%), dry skin (76%), thick nails (59%), jagged nails (29%), long/overgrown nails (17%), and skin fissures (12%). CONCLUSIONS: While the foot problems we observed were not considered serious, they could become progressively debilitating and be prevented with proper self-management guided by appropriate knowledge and skills and available supplies. We recommend the development and testing of foot care self-management interventions deliverable via mobile clinics to increase access and improve foot health outcomes.

Excluding Pulmonary Embolism with End-tidal Carbon Dioxide: Accuracy, Cost, and Harm Avoidance.

A non-randomized single center prospective, descriptive, correlational design was used to determine what end-tidal carbon dioxide (EtCO2) level provided the best sensitivity, specificity, and negative predictive value to exclude pulmonary embolism (PE) diagnosis in hemodynamically stable hospitalized adults (n = 111). The financial impact and harm avoidance of adding EtCO2 to the PE diagnostic process also were examined. PE diagnosis was determined by computed tomography pulmonary angiography (CTPA). PE prevalence was 18.9%. Mean±SD EtCO2 was lower for PE positive than negative participants (28 ± 7.8 to 33 ± 8.1 mmHg respectively 95% CI: 1.22-8.96; P = .01). For PE exclusion, an EtCO2 cutoff ≥42 mmHg yielded 100% sensitivity, 12.2% specificity, and 100% negative predictive value. For every six inpatients assessed with EtCO2, one could be saved from unnecessary CTPA. Eliminating unnecessary CTPA removes the potential harm associated with radiation and intravenous contrast exposure. Additionally, an EtCO2 cutoff ≥42 mmHg could eliminate ~$88,000/year in healthcare waste at this institution.

Diagnosis of pulmonary embolism: Following the evidence from suspicion to certainty.

Accurate, timely and cost-effective identification of pulmonary embolism remains a diagnostic challenge. This article reviews the pulmonary embolism diagnostic process with a focus on the best practice advice from the American College of Physicians. Benefits and risks of each diagnostic step are discussed. Emerging diagnostic tools, not included in the algorithm, are briefly reviewed.

Analysis of qualitative interviews about the impact of information technology on pressure ulcer prevention programs: implications for the wound, ostomy and continence nurse.

PURPOSE: The purpose of this study was to compare pressure ulcer prevention programs in 2 long-term care (LTC) facilities with diverse Information Technology Sophistication (ITS), one with high sophistication and one with low sophistication, and to identify implications for the WOC nurse. DESIGN: Secondary analysis of narrative data obtained from a mixed-methods study. SUBJECTS AND SETTING: The study setting was 2 LTC facilities in the Midwestern United States. The sample comprised 39 staff from 2 facilities, including 26 from a high-ITS facility and 13 from the low-ITS facility. Respondents included certified nurse assistants, certified medical technicians, restorative medical technicians, social workers, RNs, licensed practical nurses, information technology staff, administrators, and directors. METHODS: This study is a secondary analysis of interviews regarding communication and education strategies in 2 LTC agencies. This analysis focused on focus group interviews, which included both direct and nondirect care providers. RESULTS: Eight themes (codes) were identified in the analysis. Three themes are presented individually with exemplars of communication and education strategies. The analysis revealed specific differences between the high-ITS and low-ITS facilities in regard to education and communication involving pressure ulcer prevention. These differences have direct implications for WOC nurses consulting in the LTC setting. CONCLUSIONS: Findings from this study suggest that effective strategies for staff education and communication regarding PU prevention differ based on the level of ITS within a given facility. Specific strategies for education and communication are suggested for agencies with high ITS and agencies with low ITS.

Impact of the Health Insurance Portability and Accountability Act on participant recruitment and retention.

Recruiting and retaining an adequate sample is critical to the success of any research project involving humans. Recent reports indicate that the Health Insurance Portability and Accountability Act (HIPAA) privacy rule has adversely affected research. Few resources are available to help researchers navigate the challenges to recruitment and retention after HIPAA privacy rule implementation. This article addresses obstacles to recruitment in prospective clinical research studies related to the HIPAA privacy rule, as well as HIPAA-compliant strategies to enhance recruitment and retention. Recruitment challenges discussed include evolving interpretations of the HIPAA regulations, inability to directly contact potential participants, complexity of HIPAA-required documents, increased costs of recruitment, and an expanding administrative burden. Among the strategies addressed are preparatory research reviews, using clinical collaborators and staff liaisons, prescreening potential participants, minimizing participant burden during the consent process, enhancing participant follow-up, facilitating recruitment for future studies, and streamlining compliance training for staff.

The effect of clinically relevant pressure duration on sacral skin blood flow and temperature in patients after acute spinal cord injury.

OBJECTIVE: To test the effect of clinically relevant duration of pressure loading (2 h) on sacral skin blood flow (SBF) and skin temperature in subjects with spinal cord injury (SCI) within 24 to 96 hours after injury compared with subjects with acute orthopedic trauma and healthy subjects. DESIGN: Three-group, repeated-measures, inception cohort. SETTING: Three acute care hospitals in southern Thailand. PARTICIPANTS: Convenience sample of 20 subjects with acute SCI within 24 to 96 hours after injury. Age- and sex-matched subjects with acute orthopedic trauma (n=35) and healthy subjects (n=47) served as comparison groups. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Sacral SBF and skin temperature were measured simultaneously by using a laser Doppler sensor and thermocouple sensor, respectively, with subjects lying in the lateral (baseline, no pressure, 30 min), supine (pressure loading, 2 h), and lateral position (recovery, no pressure, 90 min). RESULTS: Baseline skin temperature was higher in subjects with acute SCI (P<.05) compared with subjects with orthopedic trauma and healthy subjects. A relative decrease in sacral SBF occurred in subjects with acute SCI (P<.01) over 2 hours of pressure loading compared with subjects with orthopedic trauma and healthy subjects. During the same time course, subjects with acute SCI had a smaller increase in sacral skin temperature compared with subjects with orthopedic trauma and healthy subjects (P<.001). During recovery, the time to the initial sacral SBF-reactive hyperemia response was shorter in subjects with acute SCI compared with subjects with orthopedic trauma (P<.001) and healthy subjects (P=.003). Additionally, the initial positive slope of the SBF reactive hyperemia response was higher in subjects with acute SCI than subjects with orthopedic trauma (P=.005) and healthy (P=.004) subjects. CONCLUSIONS: Collectively, a negative change in SBF during pressure loading plus a shorter time to increase and greater slope for SBF after pressure release reveal microvascular dysfunction in acute SCI subjects. The clinical relevance of the protocol suggests that turning interval guidelines may require reevaluation for patients with acute SCI.

Effect of oral hydration on skin microcirculation in healthy young and midlife and older adults.

Clinically undetected underhydration lowers subcutaneous tissue oxygen, impairs healing and increases wound infection. This study examined the effect of supplemental oral hydration on noninvasive measures of skin temperature (T(s)), transcutaneous skin O(2) (PtcO(2)), and CO(2) (PtcCO(2)), and skin blood flow (laser Doppler fluxmetry [Flux]=concentration of moving blood cells [CMBC] x Velocity) in healthy adults. Nineteen Control and 18 Test (Hydrated) subjects participated. Ad libitum fluid intake was allowed before the experiment. Sensors were placed on the chest, lower legs, and feet. Time 1 resting supine T(s), PtcO(2)/PtcCO(2), and Flux/CMBC/Velocity were obtained. Then, the Test group ingested 500 mL of H(2)O. Time 2 measures were obtained 30 minutes later. Data were analyzed using ANOVA. Change in T(s), PtcO(2), PtcCO(2), and Velocity did not differ between groups. Flux increased more in the Test than in the Control group (p<0.01). The Flux change was explained by a CMBC increase (p<0.05). For midlife/older subjects only, the CMBC change was greater in the Test than in the Control group (p<0.01). Flux may be sufficiently sensitive to detect microvascular changes in response to supplemental oral hydration. These data also suggest that subtle levels of hypoperfusion due to underhydration may exist in community-dwelling healthy midlife/older adults in their natural state.

Impact of pain on outcomes in long-term care residents with and without multiple sclerosis.

OBJECTIVES: To compare long-term care (LTC) residents with and without multiple sclerosis (MS); to compare admission status of pain, physical disability, pressure ulcers, depression, and cognitive performance in LTC residents with and without MS; and to examine the impact of MS and pain on outcomes 90 and 180 days after LTC admission. DESIGN: Retrospective analysis of a large data set. SETTING: LTC facilities in Missouri. PARTICIPANTS: Residents admitted to non-hospital-based LTC facilities. MEASUREMENTS: Minimum Data Set/Resident Assessment Instrument, Version 2.0; Activities of Daily Living Scale; Cognitive Performance Scale. RESULTS: Residents with and without MS had similar pain prevalence and intensity after admission, with daily pain more frequent in residents with MS (P=.03). On admission, residents with MS had more physical disability (P<.001) and a greater prevalence of pressure ulcers (P=.004) and depression (P<.001) than residents without MS. In all LTC residents, initial pain status was associated with physical disability (P<.001), pressure ulcers (P<.001), depression (P<.001), and cognitive performance (P<.001) 90 and 180 days after admission. A diagnosis of MS was associated with physical disability (P<.001) 90 and 180 days after admission and pressure ulcer development 180 days after admission (P=.02). CONCLUSION: Residents with MS were more physically disabled and had more frequent pain and a higher prevalence of pressure ulcers and depression on admission than residents without MS. Pain, or lack thereof, in residents with and without MS on admission may warn of problems that could occur within 6 months after admission to a LTC facility.

Elevated sacral skin temperature (T(s)): a risk factor for pressure ulcer development in hospitalized neurologically impaired Thai patients.

Pressure ulcer incidence and sacral skin temperature (T(s)) were measured in hospitalized neurologically impaired Thai patients ( n = 17) positioned supine and then laterally. Pressure ulcer incidence within 2 weeks of admission was 47%. Regardless of reclining position, mean sacral T(s) in subjects who developed a pressure ulcer was higher ( p < .01) than those who did not develop an ulcer. The data suggest that T(s) may increase at least 1.2 degrees C 24-96 hr before sacral pressure ulcer development. Sacral T(s) may be an objective predictor of sacral pressure ulcer development in hospitalized neurologically impaired Thai patients.

Nursing home quality and pressure ulcer prevention and management practices.

OBJECTIVES: To measure pressure ulcer quality indicator (QI) scores and to describe the self-reported skin integrity assessment, pressure ulcer risk assessment, and pressure ulcer prevention and treatment practices in long-term care facilities (LTCFs). DESIGN: Retrospective analysis of a large data set and comparative survey. SETTING: LTCFs in Missouri. PARTICIPANTS: Three hundred sixty-two LTCFs participated in the survey. Three hundred twenty-one facilities had pressure ulcer QI scores between April 1 and September 30, 1999. MEASUREMENTS: Pressure ulcer QI scores, Pressure Ulcer Prevention & Treatment Practices Survey. RESULTS: The mean+/-standard deviation pressure ulcer QI score was 10.9+/-6.2%, with a risk-adjusted score of 15.7+/-8.9% for high-risk residents and 3.1+/-3.6% for low-risk residents. Minimizing head-of-bed elevation to less than 30 degrees was used by fewer than 20% of facilities. More than 40% of facilities used a risk assessment tool that was not evidence based. Fewer than 13% of facilities used the Agency for Health Care Policy and Research pressure ulcer prevention and treatment guidelines. No relationship was found between the number of prevention strategies (P=.892) or the number of treatment strategies (P=.921) and the pressure ulcer QI scores. CONCLUSION: Valid and reliable pressure ulcer risk assessment tools are seriously underused. Evidence-based pressure ulcer prevention and treatment guidelines appear to be rarely implemented. This study provides a basis for developing educational and quality improvement programs and future research related to pressure ulcer prevention and treatment in LTCFs.

Skin assessment and pressure ulcer care in hospital-based skilled nursing facilities.

The Minimum Data Set, a comprehensive assessment tool for nursing home residents, is used for clinical decision-making, research, quality improvement, and Medicare and Medicaid reimbursement. Within the Minimum Data Set, pressure ulcers and skin condition are evaluated. Because information about pressure ulcer prevalence and care in hospital-based skilled nursing facilities is sparse, a study was conducted to: a) determine pressure ulcer prevalence upon admission to hospital-based skilled nursing facilities in the state of Missouri, and b) ascertain methods of assessment, treatment, and documentation of skin and pressure ulcer care in these facilities. Prevalence data were obtained from analysis of the Minimum Data Set data, and a survey was conducted to obtain skin care practices. The vast majority of residents (96%) were admitted from acute care facilities, and pressure ulcer prevalence on admission was 18.4% +/- 8.0%. Seventy-seven percent (77%) of the 88 surveys mailed were returned. The Braden or Norton Scale for risk assessment is reportedly used by 55% of facilities; whereas, 35% use a facility-developed tool. Commonly reported pressure ulcer prevention/treatment interventions used include: dietitian referral, use of barrier ointments, and a written repositioning schedule. Incontinence management and minimizing the head of bed elevation were infrequently used. Nearly one-half (47%) of facilities reported daily reassessment and documentation of wound status, suggesting less-than-optimal, time-consuming wound care practices. Despite the limitations inherent in survey designs and the use of databases such as the Minimum Data Set, the results of this study suggest that pressure ulcers are a common problem in acute care and hospital-based skilled nursing facilities and research-based risk assessment, prevention, and wound assessment strategies have not been widely implemented. The results of this study provide a basis for developing educational programs and a guide for future research.

Why older adults with light care needs enter and remain in nursing homes.

Many patients in nursing homes receive limited services. In 1996, approximately 17% of the 1.6 million nursing home residents received assistance with two or less activities of daily living (ADL). This descriptive study addressed this issue by investigating why residents with light care needs enter and remain in nursing homes. Residents with light care needs (N = 20) identified by directors of nursing were interviewed to elicit why they entered and remain in nursing homes. Their care level was estimated using the Minimum Data Set (MDS) and Resource Utilization Groups, Version III (RUG-III). In this study, older adults with light care needs who decide to enter and remain in nursing homes were found to be influenced by a prior hospitalization or a health event; the perceived inability to manage instrumental ADLs (IADLs), ADLs, or health monitoring at home; and lack of knowledge about alternatives to nursing home care. This study demonstrates the vital role nurse case managers can play in both acute care settings and nursing homes. They can help older adults with light care needs to make informed decisions about long-term care, seek out community options, and set in place assistive care systems that can help them age in the community.
