Effect of a Statewide Fall Prevention Program on Incidence of Femoral Fractures in Residents of Long-Term Care Facilities

OBJECTIVES: To evaluate the effect of a statewide dissemination of a modified evidence-based fall prevention program on incidence of femoral fractures in nursing homes.
DESIGN: Observational study of a staged implementation of a successful fall prevention program.
SETTING: One thousand three hundred fifty-nine nursing homes in two federal states in the south of Germany.
PARTICIPANTS: Nine thousand seventy-seven residents in the intervention homes and 43,583 residents in control homes from the same and a different federal state.
INTERVENTION: Staff education on fall prevention, advice on environmental adaptations, and progressive strength and balance training over at least 1 year.
MEASUREMENTS: Incident femoral fractures.
RESULTS: One thousand five hundred eighteen femoral fractures occurred in the total study population during the intervention period. The crude incidence rate of femoral fractures was 39.5/1,000 person-years in residents from the intervention homes and 40.9 and 39.7/1,000 person-years in residents from two sets of control homes. In a multivariate model, there was no evidence of an effect of the fall prevention program on incidence of femoral fracture when compared with control homes from the same federal state (adjusted hazard ratio (AHR)=0.96, 95% confidence interval (CI)=0.83–1.11) or from a different federal state (AHR=1.00, 95% CI=0.86–1.16).
CONCLUSION: The statewide dissemination of a multifactorial fall prevention program did not appear to reduce the burden of femoral fractures in residents of nursing homes.     

Prevalence of Methicillin-Resistant Staphylococcus aureus Colonization in Residents and Staff in Nursing Homes in Northern Ireland

OBJECTIVES: To determine the prevalence of, and factors associated with, methicillin-resistant Staphylococcus aureus (MRSA) colonization in residents and staff in nursing homes in one geographically defined health administration area of Northern Ireland.
DESIGN: Point prevalence study.
SETTING: Nursing homes.
PARTICIPANTS: Residents and staff in nursing homes.
MEASUREMENTS: Nasal swabs were taken from all consenting residents and staff. If relevant, residents also provided urine samples, and swabs were taken from wounds and indwelling devices.
RESULTS: A total of 1,111 residents (66% of all residents) and 553 staff (86% of available staff) in 45 nursing homes participated. The combined prevalence rate of MRSA in the resident population was 23.3% (95% confidence interval (CI)=18.8–27.7%) and 7.5% in staff (95% CI=5.1–9.9%). Residents who lived in nursing homes that were part of a chain were more likely to be colonized with MRSA (odds ratio (OR)=1.91, 95% CI=1.21–3.02) than those living in independently owned facilities. Residents were also more likely to be colonized if they lived in homes in which more than 12.5% of all screened healthcare staff (care assistants and nurses) were colonized with MRSA (OR=2.46, 95% CI=1.41–4.29) or if they lived in homes in which more than 15% of care assistants were colonized with MRSA (OR=2.64, 95% CI=1.58–4.42).
CONCLUSION: The findings suggest that there is substantial colonization of MRSA in nursing home residents and staff in this one administrative health area. Implementation of infection control strategies should be given high priority in nursing homes.     

Mortality and adverse health events in newly admitted nursing home residents with and without dementia

OBJECTIVES: To evaluate the association between dementia and mortality, adverse health events, and discharge disposition of newly admitted nursing home residents. It was hypothesized that residents with dementia would die at a higher rate and develop more adverse health events (e.g., infections, fevers, pressure ulcers, falls) than residents without dementia because of communication and self-care difficulties. DESIGN: An expert clinician panel diagnosed an admission cohort from a stratified random sample of 59 Maryland nursing homes, between 1992 and 1995. The cohort was followed for up to 2 years or until discharge. SETTING: Fifty-nine Maryland nursing homes. PARTICIPANTS: Two thousand one hundred fifty-three newly admitted residents aged 65 and older not having resided in a nursing home for 8 or more days in the previous year. MEASUREMENTS: Mortality, infection, fever, pressure ulcers, fractures, and discharge home. RESULTS: Residents with dementia had significantly lower overall rates of infection (relative risk (RR)=0.77, 95% confidence interval (CI)=0.70-0.85) and mortality (RR=0.61, 95% CI=0.53-0.71) than those without dementia, whereas rates of fever, pressure ulcers, and fractures were similar for the two groups. These results persisted when rates were adjusted for demographic characteristics, comorbid conditions, and functional status. During the first 90 days of the nursing home stay, residents with dementia had significantly lower rates of mortality if not admitted for rehabilitative care under a Medicare qualifying stay (RR=0.25, 95% CI=0.14-0.45), were less often discharged home (RR=0.33, 95% CI=0.28-0.38), and tended to have lower fever rates (RR=0.78, 95% CI=0.63-0.96) than residents without dementia. CONCLUSION: Newly admitted nursing home residents with dementia have a profile of health events that is distinct from that of residents without dementia, indicating that the two groups have different long-term care needs. Results suggest that further investigation of whether residents with dementia can be well managed in alternative residential settings would be valuable.     

Cost analysis of nursing home registered nurse staffing times

Objectives: To examine potential cost savings from decreased adverse resident outcomes versus additional wages of nurses when nursing homes have adequate staffing.
Design: A retrospective cost study using differences in adverse outcome rates of pressure ulcers (PUs), urinary tract infections (UTIs), and hospitalizations per resident per day from low staffing and adequate staffing nursing homes. Cost savings from reductions in these events are calculated in dollars and compared with costs of increasing nurse staffing.
Setting: Eighty-two nursing homes throughout the United States.
Participants: One thousand three hundred seventy-six frail elderly long-term care residents at risk of PU development.
Measurements: Event rates are from the National Pressure Ulcer Long-Term Care Study. Hospital costs are estimated from Medicare statistics and from charges in the Healthcare Cost and Utilization Project. UTI costs and PU costs are from cost-identification studies. Time horizon is 1 year; perspectives are societal and institutional.
Results: Analyses showed an annual net societal benefit of $3,191 per resident per year in a high-risk, long-stay nursing home unit that employs sufficient nurses to achieve 30 to 40 minutes of registered nurse direct care time per resident per day versus nursing homes that have nursing time of less than 10 minutes. Sensitivity analyses revealed a robust set of estimates, with no single or paired elements reaching the cost/benefit equality threshold.
Conclusion: Increasing nurse staffing in nursing homes may create significant societal cost savings from reduction in adverse outcomes. Challenges in increasing nurse staffing are discussed.     

Organizational characteristics and restraint use for hospitalized nursing home residents

OBJECTIVES: To examine the effect of organizational characteristics on physical restraint use for hospitalized nursing home residents.
DESIGN: Secondary analysis of data obtained between 1994 to 1997 in a prospective phase lag design experiment using an advanced practice nurse (APN) intervention aimed at reducing physical restraint for a group of hospitalized nursing home residents.
SETTING: Eleven medical and surgical units in one 600-bed teaching hospital.
PARTICIPANTS: One hundred seventy-four nursing home residents aged 61 to 100, hospitalized for a total of 1,085 days.
MEASUREMENTS: Physical restraint use, APN intervention, age, perceived fall risk, behavioral phenomena, perceived treatment interference, mental state, severity of illness, day of week, patient–registered nurse (RN) ratio, patient–total nursing staff ratio, and skill mix.
RESULTS: Controlling for the APN intervention, age, and patient behavioral characteristics (all of which increased the likelihood of restraint use), weekend days as an organizational characteristic significantly increased the odds of restraint (weekend day and patient–RN ratio on physical restraint use: odds ratio (OR) = 1.92, 95% confidence interval (CI) = 1.38–2.68, P < .001; weekend day and patient–total staff ratio on physical restraint use: OR = 1.91, 95% CI = 1.37–2.66, P < .001; weekend day and skill mix on physical restraint use: OR = 1.91, 95% CI = 1.37–2.67, P < .001).
CONCLUSION: Key findings suggest that organization of hospital care on weekends and patient characteristics that affect communication ability, such as severely impaired mental state, English as a second language, sedation, and sensory-perceptual losses, may be overlooked variables in restraint use.     

The Influence of Long-Term Care Insurance on the Likelihood of Nursing Home Admission

OBJECTIVES: To determine the effect of long-term care (LTC) insurance on nursing home use.
DESIGN: Longitudinal analysis, 1998 to 2006 waves of the Health Retirement Study.
SETTING: Community-dwelling nationally representative sample.
PARTICIPANTS: Nineteen thousand one hundred seventy adults aged 50 and older, 1998 wave.
METHODS: Two groups of respondents were created at baseline: those with and without an LTC insurance policy. Respondents admitted to the nursing home from 1998 to 2006 were identified. Propensity scores were used to control for known predictors of LTC insurance possession. A Cox proportional hazards model was used to compare the probability of nursing home admission over 8 years of follow-up for respondents possessing LTC insurance and those without a policy.
RESULTS: Of the 19,170 respondents aged 50 and older in 1998, 1,767 (9.2%) possessed LTC insurance. A total of 1,778 (8.5%) were admitted to a nursing home during the 8-year period: 149 (8.7%) of those with LTC insurance and 1,629 (8.4%) of those without LTC insurance. The hazard ratio, adjusted for propensity score, for those with LTC insurance entering a nursing home compared with those without was 1.07 (95% confidence interval=0.83–1.38). Likelihood of nursing home admission was relatively low because the low-risk population included in the study, limiting the power to detect small differences in risk of nursing home utilization between groups.
CONCLUSION: There was no difference in nursing home utilization between low-risk older adults who did and did not possess an LTC insurance policy.     

Clinical Features to Identify Urinary Tract Infection in Nursing Home Residents: A Cohort Study

OBJECTIVES: To identify clinical features associated with bacteriuria plus pyuria in noncatheterized nursing home residents with clinically suspected urinary tract infection (UTI).
DESIGN: Prospective, observational cohort study from 2005 to 2007.
SETTING: Five New Haven, Connecticut area nursing homes.
PARTICIPANTS: Five hundred fifty-one nursing home residents each followed for 1 year for the development of clinically suspected UTI.
MEASUREMENTS: The combined outcome of bacteriuria (>100,000 colony forming units from urine culture) plus pyuria (>10 white blood cells from urinalysis).
RESULTS: After 178,914 person-days of follow-up, 228 participants had 399 episodes of clinically suspected UTI with a urinalysis and urine culture performed; 147 episodes (36.8%) had bacteriuria plus pyuria. The clinical features associated with bacteriuria plus pyuria were dysuria (relative risk (RR)=1.58, 95% confidence interval (CI)=1.10–2.03), change in character of urine (RR=1.42, 95% CI=1.07-1.79), and change in mental status (RR=1.38, 95% CI=1.03–1.74).
CONCLUSION: Dysuria, change in character of urine, and change in mental status were significantly associated with the combined outcome of bacteriuria plus pyuria. Absence of these clinical features identified residents at low risk of having bacteriuria plus pyuria (25.5%), whereas presence of dysuria plus one or both of the other clinical features identified residents at high risk of having bacteriuria plus pyuria (63.2%). Diagnostic uncertainty still remains for the vast majority of residents who meet only one clinical feature. If validated in future cohorts, these clinical features with bacteriuria plus pyuria may serve as an evidence-based clinical definition of UTI to assist in management decisions.     

Stage 2 pressure ulcer healing in nursing homes

OBJECTIVES: To identify resident and wound characteristics associated with Stage 2 pressure ulcer (PrU) healing time in nursing home residents. DESIGN: Retrospective cohort study with convenience sampling. SETTING: One hundred two nursing homes participating in the National Pressure Ulcer Long‐Term Care Study (NPULS) in the United States. PARTICIPANTS: Seven hundred seventy‐four residents aged 21 and older with length of stay of 14 days or longer who had at least one initial Stage 2 (hereafter Stage 2) PrU. MEASUREMENTS: Data collected for each resident over a 12‐week period included resident characteristics and PrU characteristics, including area when first reached Stage 2. Data were obtained from medical records and logbooks. RESULTS: There were 1,241 initial Stage 2 PrUs on 774 residents; 563 (45.4%) healed. Median time to heal was 46 days. Initial area was significantly associated with days to heal. Using Kaplan‐Meier survival analyses, median days to heal was 33 for small (≤1 cm²), 53 days for medium (>1 to ≤4 cm²), and 73 days for large (>4 cm²) ulcers. Using Cox proportional hazard regression models to examine effects of multiple variables simultaneously, small and medium ulcers and ulcers on residents with agitation and those who had oral eating problem healed more quickly, whereas ulcers on residents who required extensive assistance with seven to eight activities of daily living (ADLs), who temporarily left the facility for the emergency department (ED) or hospital, or whose PrU was on an extremity healed more slowly. CONCLUSION: PrUs on residents with agitation or with oral eating problems were associated with faster healing time. PrUs located on extremities, on residents who went temporarily to the ED or hospital, and on residents with high ADL disabilities were associated with slower healing time. Interaction between PrU size and place of onset was also associated with healing time. For PrU onset before or after admission to the facility, smaller size was associated with faster healing time.     

Is Dementia Special Care Really Special? A New Look at an Old Question

OBJECTIVES: To quantify differences in care provided to nursing home (NH) residents with dementia living on and off dementia special care units (SCUs).
DESIGN: Cross-sectional study using propensity score adjustment for resident and NH characteristics.
SETTING: Free-standing NHs in nonrural U.S. counties that had an SCU in 2004 (N=1,896).
PARTICIPANTS: Long-stay (≥90 days) NH residents with a diagnosis of Alzheimer's disease or dementia and at least moderate cognitive impairment (N=69,131).
MEASUREMENTS: Resident-level NH care processes such as physical restraints, bed rails, feeding tubes, psychotropic medications, and incontinence care.
RESULTS: There was no difference in the use of physical restraints (adjusted odds ratio (AOR)=0.94, 95% confidence interval (CI)=0.79–1.11), but SCU residents were less likely to have had bed rails (AOR=0.55, 95% CI=0.46–0.64) and to have been tube fed (AOR=0.36, 95% CI=0.30–0.43). SCU residents were more likely to be on toileting plans (AOR=1.23, 95% CI=1.08–1.39) and less likely to use pads or briefs in the absence of a toileting plan (AOR=0.73, 95% CI=0.61–0.88). SCU residents were more likely to have received psychotropic medications (AOR=1.23, 95% CI=1.05–1.44), primarily antipsychotics (SCU=44.9% vs non-SCU=30.0%).
CONCLUSION: SCU residents received different care than comparable non-SCU residents. Most strikingly, SCU residents had greater use of antipsychotic medications.     

Prevention of falls in nursing homes: subgroup analyses of a randomized fall prevention trial

OBJECTIVES: To evaluate the effectiveness of a multifactorial fall prevention program in prespecified subgroups of nursing home residents.
DESIGN: Secondary analysis of a cluster-randomized, controlled trial.
SETTING: Six nursing homes in Germany.
PARTICIPANTS: Seven hundred twenty-five long-stay residents; median age 86; 80% female.
INTERVENTION: Staff and resident education on fall prevention, advice on environmental adaptations, recommendation to wear hip protectors, and progressive balance and resistance training.
MEASUREMENTS: Time to first fall and the number of falls. Falls were assessed during the 12-month intervention period. Univariate regression analyses were performed, including a confirmatory test of interaction.
RESULTS: The intervention was more effective in people with cognitive impairment (hazard ratio (HR)=0.49, 95% confidence interval (CI)=0.35–0.69) than in those who were cognitively intact (HR=0.91, 95% CI=0.68–1.22), in people with a prior history of falls (HR=0.47, 95% CI=0.33–0.67) than in those with no prior fall history (HR=0.77, 95% CI=0.58–1.01), in people with urinary incontinence (HR=0.59, 95% CI=0.45–0.77) than in those with no urinary incontinence (HR=0.98, 95% CI=0.68–1.42), and in people with no mood problems (incidence rate ratio (IRR)=0.41, 95% CI=0.27–0.61) than in those with mood problems (IRR=0.74, 95% CI=0.51–1.09).
CONCLUSION: The effectiveness of a multifactorial fall prevention program differed between subgroups of nursing home residents. Cognitive impairment, a history of falls, urinary incontinence, and depressed mood were important in determining response.     

Pressure ulcer prevalence in long-term nursing home residents since the implementation of OBRA '87. Omnibus Budget Reconciliation Act

OBJECTIVES: To evaluate change in pressure ulcer prevalence in long-term nursing home residents since the implementation of the Omnibus Budget Reconciliation Act of 1987 (OBRA '87). DESIGN: Cross-sectional comparison of two time periods. SETTING: Ninety-two nursing homes scheduled for a quality-of-care survey randomly selected from 22 representative states. PARTICIPANTS: Four thousand six hundred seventy-nine residents who had resided in the facility for at least 100 days were evaluated: 2,336 during 1992-1994 and 2,343 during 1997-1998. MEASUREMENTS: Trained registered nurses collected data on pressure ulcer prevalence, stage, and risk factors from medical record review during on-site evaluations. Risk-adjusted differences were estimated using logistic regression. RESULTS: Unadjusted prevalence rates for all stages of pressure ulcers (8.52% vs 8.54%, P =.983) and those rated stage 2 or greater (5.31% vs 5.63%, P =.624) did not differ between the two time periods. After adjustment for urinary incontinence, immobility, poor nutrition, and history of previous pressure ulcers, the relative odds of having a pressure ulcer in 1992/4 versus 1997/8 was 1.06 (95% confidence interval (CI) = 0.84-1.34) for all stages and 1.21 (95% CI = 0.92-1.60) for stages 2 and greater. CONCLUSIONS: No change in pressure ulcer prevalence was demonstrated since implementation of OBRA '87 in this nationally derived sample of long-term nursing home residents.     

The effect of Evercare on hospital use

Objectives: To examine the use of hospital and related medical care services of a novel managed care program using nurse practitioners (NPs) and directed specifically at long-stay nursing home residents.
Design: Quasi-experimental posttest design with two control groups to minimize selection bias.
Setting: Nursing homes.
Participants: Evercare enrollees in five sites were compared with two sets of controls: nursing home residents in the same nursing homes who did not enroll in Evercare (control-in) and residents of nursing homes that did not participate in Evercare (control-out).
Measurements: Utilization data from Medicare and United Healthcare (the parent corporation for Evercare) were obtained for slightly more than 2 years. Patterns of use were assessed by calculating the monthly use rate for each group and aggregating to form annual rates. Usages addressed included hospital admissions and days, emergency room visits, therapy services, mental health services, and podiatry. Adjustments were made to correct for age, race, and sex. Because the groups differed in terms of the rate of cognitive impairment, the analysis was stratified on this variable.
Results: The incidence of hospitalizations was twice as high in control residents as in Evercare residents (4.63 and 4.67 per 100 enrollees per month vs 2.43 in the 15 months after census, P <.001). This difference corresponded to Evercare's use of intensive service days. The same pattern held for preventable hospitalizations (0.80 and 0.86 vs 0.28, P <.001). The pattern held when residents were stratified by cognitive status. On average, using a NP is estimated to save about $103,000 a year in hospital costs per NP.
Conclusion: The use of active primary care provided by NPs may have prevented the occurrence of some hospitalizable events, but its major effect was allowing cases to be managed more cost-effectively.     

The Overlap Syndrome of Depression and Delirium in Older Hospitalized Patients

OBJECTIVES: To measure the prevalence, predictors, and posthospitalization outcomes associated with the overlap syndrome of coexisting depression and incident delirium in older hospitalized patients.
DESIGN: Secondary analysis of prospective cohort data from the control group of the Delirium Prevention Trial.
SETTING: General medical service of an academic medical center. Follow-up interviews at 1 month and 1 year post-hospital discharge.
PARTICIPANTS: Four hundred fifty-nine patients aged 70 and older who were not delirious at hospital admission.
MEASUREMENTS: Depressive symptoms assessed at hospital admission using the 15-item Geriatric Depression Scale (cutoff score of 6 used to define depression), daily assessments of incident delirium from admission to discharge using the Confusion Assessment Method, activities of daily living at admission and 1 month postdischarge, and new nursing home placement and mortality determined at 1 year.
RESULTS: Of 459 participants, 23 (5.0%) had the overlap syndrome, 39 (8.5%) delirium alone, 121 (26.3%) depression alone, and 276 (60.1%) neither condition. In adjusted analysis, patients with the overlap syndrome had higher odds of new nursing home placement or death at 1 year (adjusted odds ratio (AOR)=5.38, 95% confidence interval (CI)=1.57–18.38) and 1-month functional decline (AOR=3.30, 95% CI=1.14–9.56) than patients with neither condition.
CONCLUSION: The overlap syndrome of depression and delirium is associated with significant risk of functional decline, institutionalization, and death. Efforts to identify, prevent, and treat this condition may reduce the risk of adverse outcomes in older hospitalized patients.     

Residual urine as a risk factor for lower urinary tract infection: a 1-year follow-up study in nursing homes

OBJECTIVES: To determine whether postvoid urine is a risk factor for the development of lower urinary tract infections (UTIs) in nursing home residents.
DESIGN: Prospective surveillance with a follow-up period of 1 year.
SETTING: Six Norwegian nursing homes.
PARTICIPANTS: One hundred fifty nursing home residents.
METHODS: Postvoid residual (PVR) urine volumes were measured using a portable ultrasound. UTIs were registered prospectively for 1 year.
RESULTS: Ninety-eight residents (65.3%) had a PVR less than 100 mL, and 52 (34.7%) had a PVR of 100 mL or greater. During the follow-up period, 51 residents (34.0%) developed one or more UTIs. The prevalence of UTI in women was higher than in men (40.4% vs 19.6%; P =.02). There was no significant difference in mean PVR between residents who did and did not develop a UTI (79 vs 97 mL, P =.26). PVR of 100 mL or greater was not associated with greater risk of developing a UTI ( P =.59).
CONCLUSION: High PVR is common in nursing home residents. No association between PVR and UTI was found.     

Factors Associated with Antimicrobial Use in Nursing Homes: A Multilevel Model

OBJECTIVES: To describe antimicrobial prescribing patterns in nursing homes. DESIGN: Retrospective, observational study. SETTING: Total of 73 nursing homes in four U.S. states; study period was from September 1, 2001, through February 28, 2002. PARTICIPANTS: Four thousand seven hundred eighty nursing home residents. MEASUREMENTS: Number and type of antimicrobials, indication for their use, and resident and facility factors associated with antimicrobial use in nursing homes. RESULTS: Of 4,780 residents, 2,017 (42%) received one or more antibiotic courses. Overall, residents received a mean of 4.8 courses/1,000 resident‐days (mean facility range 0.4–23.5). In multivariable analysis, higher probability of nursing home discharge and of being categorized in the rehabilitation, extensive services, special care, or clinically complex Resource Utilization Groups were associated with higher rates of antimicrobial usage. Three drug classes accounted for nearly 60% of antimicrobial courses—fluoroquinolones (38%), first‐generation cephalosporins (11%), and macrolides (10%). The most common conditions for which antimicrobials were prescribed were respiratory tract (33%) and urinary tract (32%) infections. CONCLUSION: Antibiotic use is variable in nursing homes. Targeting educational and other antimicrobial use interventions to the treatment of certain clinical diagnoses and conditions may be an appropriate strategy for optimizing antimicrobial use in this setting.     

Nursing home patients transferred by ambulance to a VA emergency department

Nursing home residents are frequently transferred to hospital emergency departments. Delayed transfer may lead to poor outcomes. However, inappropriate transfer of the frail elderly may cause social and financial problems. We prospectively evaluated 221 consecutive ambulance transfers from community nursing homes to a VA emergency department. The objectives of the study were to describe the process and outcomes of transferred patients and to determine if alternative interventions were feasible. The results indicate that the problems of nearly half the study group could have been treated at the nursing home by a visiting physician with minimal medical equipment. Those admitted to the hospital (52%) were seriously ill, had prolonged lengths of stay (23.6 days), and had a high mortality rate (11%). Complex issues of physician reimbursement, proprietary nursing home budgeting, and day-to-day expediency appear to be involved in decisions to transport patients by ambulance to VA emergency departments.     

A randomized clinical trial on preventing pressure ulcers with wheelchair seat cushions

OBJECTIVES: To determine the efficacy of skin protection wheelchair seat cushions in preventing pressure ulcers in the elderly nursing home population. DESIGN: Clinical trial with participants assigned at random to a skin protection or segmented foam cushion. Two hundred thirty‐two participants were recruited between June 2004 and May 2008 and followed for 6 months or until pressure ulcer incidence. SETTING: Twelve nursing homes. PARTICIPANTS: Nursing home residents aged 65 and older who were using wheelchairs for 6 or more hours per day and had a Braden score of 18 or less and a combined Braden activity and mobility score of 5 or less. Participants were recruited from a referred sample. INTERVENTION: All participants were provided with a fitted wheelchair and randomized into skin protection (SPC, n=113) or segmented foam (SFC, n=119) cushion groups. The SPC group received an air, viscous fluid and foam, or gel and foam cushion. The SFC group received a 7.6‐cm crosscut foam cushion. MEASUREMENTS: Pressure ulcer incidence over 6 months for wounds near the ischial tuberosities (IT ulcers) were measured. Secondary analysis was performed on combined IT ulcers and ulcers over the sacrum and coccyx (sacral ulcers). RESULTS: One hundred eighty participants reached a study end point, and 42 were lost to follow‐up. Ten did not receive the intervention. There were eight (6.7%) IT ulcers in the SFC group and one (0.9%) in the SPC group (P=.04). There were 21 (17.6%) combined IT and sacral ulcers in the SFC group and 12 (10.6%) in the SPC group (P=.14). CONCLUSION: Skin protection cushions used with fitted wheelchairs lower pressure ulcer incidence for elderly nursing home residents and should be used to help prevent pressure ulcers.     

A comparative study of community- and nursing home-acquired empyema thoracis

OBJECTIVES: To compare the clinical presentation, microbiological features, and outcomes of patients with community-acquired empyema (CAE) with those of patients with nursing home-acquired empyema (NHAE).
DESIGN: A retrospective observational study.
SETTING: Three tertiary care centers.
PARTICIPANTS: One hundred fourteen patients admitted from the community and 55 patients transferred from nursing homes.
MEASUREMENTS: Baseline sociodemographic information, activities of daily living, Charlson Comorbidity Index score, and clinica, and microbiologic data were obtained. Outcome was assessed at hospital discharge and 6 months postdischarge.
RESULTS: Patients admitted from nursing homes had a delayed presentation, with dyspnea, weight loss, and anemia as the predominant manifestation. Patients with CAE presented more acutely, with fever, cough, and chest pain. Anaerobic organisms were more commonly isolated from patients with NHAE. The success rate of nonsurgical intervention was significantly lower for the NHAE patients than for the CAE group (39% vs 63; P =.01). In-hospital mortality was not significantly different between the two groups (NHAE, 18%; CAE, 8%; P =.09). In a Cox regression analysis, preadmission functional status (hazard ratio (HR)=1.26, 95% confidence interval (CI)=1.19–1.4; P <.001) and surgical intervention (HR=0.47, 95% CI=0.24–0.92; P =.03) were the only variables highly correlated with long-term outcome.
CONCLUSION: Patients admitted with NHAE have distinctly different clinical and microbiological presentation from that of patients with CAE. Because of the delayed presentation in patients with NHAE, medical treatment alone may be associated with higher rate of failure. Surgical therapy should be considered for selected cases, with the aim of improving long-term survival.
