Background
Lewy body dementia, consisting of both dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), is considerably under-recognised clinically compared with its frequency in autopsy series.
AimsThis study investigated the clinical diagnostic pathways of patients with Lewy body dementia to assess if difficulties in diagnosis may be contributing to these differences.
MethodWe reviewed the medical notes of 74 people with DLB and 72 with non-DLB dementia matched for age, gender and cognitive performance, together with 38 people with PDD and 35 with Parkinson's disease, matched for age and gender, from two geographically distinct UK regions.
ResultsThe cases of individuals with DLB took longer to reach a final diagnosis (1.2 v. 0.6 years, P = 0.017), underwent more scans (1.7 v. 1.2, P = 0.002) and had more alternative prior diagnoses (0.8 v. 0.4, P = 0.002), than the cases of those with non-DLB dementia. Individuals diagnosed in one region of the UK had significantly more core features (2.1 v. 1.5, P = 0.007) than those in the other region, and were less likely to have dopamine transporter imaging (P < 0.001). For patients with PDD, more than 1.4 years prior to receiving a dementia diagnosis: 46% (12 of 26) had documented impaired activities of daily living because of cognitive impairment, 57% (16 of 28) had cognitive impairment in multiple domains, with 38% (6 of 16) having both, and 39% (9 of 23) already receiving anti-dementia drugs.
ConclusionsOur results show the pathway to diagnosis of DLB is longer and more complex than for non-DLB dementia. There were also marked differences between regions in the thresholds clinicians adopt for diagnosing DLB and also in the use of dopamine transporter imaging. For PDD, a diagnosis of dementia was delayed well beyond symptom onset and even treatment.

Establishing a clinical diagnosis of infection in residents of long-term–care facilities (LTCFs) is difficult. As a result, deciding when to initiate antibiotics can be particularly challenging. This article describes the establishment of minimum criteria for the initiation of antibiotics in residents of LTCFs. Experts in this area were invited to participate in a consensus conference. Using a modified delphi approach, a questionnaire and selected relevant articles were sent to participants who were asked to rank individual signs and symptoms with respect to their relative importance. Using the results of the weighting by participants, a modification of the nominal group process was used to achieve consensus. Criteria for initiating antibiotics for skin and soft-tissue infections, respiratory infections, urinary infections, and fever where the focus of infection is unknown were developed.

There is intense antimicrobial use in long-term-care facilities (LTCFs), and studies repeatedly document that much of this use is inappropriate. The current crisis in antimicrobial resistance, which encompasses the LTCF, heightens concerns of antimicrobial use. Attempts to improve antimicrobial use in the LTCF are complicated by characteristics of the patient population, limited availability of diagnostic tests, and the virtual absence of relevant clinical trials. This position paper recommends approaches to management of common infections in LTCF patients and proposes minimal standards for an anti-microbial review program. In developing these recommendations, the position paper acknowledges the unique aspects of provision of care in the LTCF.

Tetanus, one of the oldest diseases known to man, continues to exact a tremendous toll worldwide. While the incidence of tetanus has declined dramatically in the United States in this century, more than 50 cases are reported to the Centers for Disease Control and Prevention (CDC) each year. Two thirds of these cases are elderly patients. Some estimate that the actual number of cases may be two to four times greater than the number reported. The overall reported case fatality rate is about 20% to 30%, but is greater than 50% for those older than 60 years.

Objectives:
To determine the frequency of recognition of methicillin-resistant Staphylococcus aureus (MRSA) as an infection control problem and its prevalence among long-term care facilities, and to evaluate whether certain long-term care facility characteristics such as bed size, ownership, level of infection control activity, and frequency of resident transfers to acute care hospitals are related to the recognition or prevalence of MRSA in this setting.
Design:Questionnaire survey.
Setting:Seventy-five long-term care facilities in the 8 counties of western New York.
Results:Seventy-five of 81 (92.6%) long-term care facilities returned a completed questionnaire. Seventy-nine percent were considered to have a “limited” level of infection control activity (part-time infection control practitioner who spent less than 10 hours a week on infection control activities). The larger the long-term care facility, the more time was spent on infection control activities (p = .01). Seventy-two percent of the long-term care facilities screened new admissions for MRSA by reviewing culture reports; 69% of the long-term care facilities had a specific infection control policy for MRSA. Sixteen of the 75 (21%) facilities felt they had an infection control problem with MRSA. By univariate analysis, the only characteristic significantly associated with this recognition was use of nurse practitioners or physician assistants by a facility (p<.05). Eighty-one percent of the 75 long-term care facilities had identified one or more patients with MRSA in the year prior to the survey. By univariate analysis, the only characteristics that were significantly associated with the number of residents with MRSA were the monthly average number of residents transferred to acute care facilities (p = .034) and facility bed size (p= .022); there was also a trend toward increasing intensity of infection control activities (p= .085). However, facility bed size and the average number of resident transfers per month to acute care facilities were strongly associated (p = .0002). By stepwise logistic regression analysis, only bed size was an independent predictor of the number of residents with MRSA. Many long-term care facilities had tried to eradicate MRSA; ciprofloxacin was most commonly used to eradicate MRSA.
Conclusions:The vast majority of the 75 long-term care facilities in the 8 counties of western New York have identified patients with MRSA, although only a minority (21%) of them actually believed that an infection control problem existed. Facility size (a surrogate for the monthly average number of resident transfers to acute care facilities) seems to be an important factor in determining the number of residents with MRSA in long-term care facilities in our geographic region. The major longitudinal studies of MRSA in such facilities have so far been done only in Veterans Affairs facilities. Further studies are needed in freestanding long-term care facilities, the largest group of long-term care facilities in the United States, to determine the epidemiology of MRSA in this setting and to develop practical and valid infection control methods for residents with MRSA.

The common parasitic infestation of scabies is an international microscopic terrorist, frequently occurring in long-term care facilities. Disruptive outbreaks have been reported in long-term care facilities throughout North America, Europe, and Israel. Once scabies is reported, the normal operations of a facility may be disrupted for several months at a time. Psychogenic scabies, threatened mass resignations of staff, and extensive local media coverage have been unwelcome sequelae of long-term care facility outbreaks.
When confronted with an infestation, nursing staff and management are frequently left on their own to come up with a plan to eradicate the infestation. This may result in either inadequate treatment of infected individuals or excessive measures for the long-term care facility, such as closing admissions, banning visitors, and periodic mass “prophylaxis” treatment. Effective and efficient management of scabies outbreaks requires knowledge of the unique features of long-term care scabies and a systematic, yet practical, approach to treatment.

No single virus has the health impact of influenza. Influenza has remained epidemiologically important because it escapes host immune pressure through antigenic variation, is highly contagious, and can cause pneumonia and death in the most susceptible hosts. Viral transmission is most efficient where contact between susceptible hosts is greatest. For humans, this includes institutional settings such as daycare centers, schools, hospitals, and long-term care facilities.
Of the three types of influenza, influenza C is relatively nonvirulent. Influenza B is most virulent in children; its antigenic stability presumably allows the adult population to benefit from acquired immunity. Influenza A is virulent in people of all ages, especially in those at the extremes of age or with immunocompromising disease; the attack rate in persons over 70 years of age is four times that of adults under 40 years of age. A major factor accounting for recurrent influenza A epidemics is change in the virus (antigenic drift and shift) that renders the vaccine less efficacious. Influenza epidemics cost billions of dollars and result in thousands of deaths annually. This discussion will focus on the prevention and treatment of influenza A in the long-term care facility.

Clostridium difficile is a major cause of gastrointestinal infections. In 1978, Bartlett and colleagues identified C difficile and its toxin as the cause of the antibiotic-associated pseudomembranous colitis (PMC). Within a few years, there was the development of a diagnostic assay, a description of a clinical and pathological spectrum of the disease, a definition of risk factors and characterization of the two toxins that account for the pathological event. Additional information regarding the microbiology, pathogenesis, clinical manifestations, diagnosis and treatment has rapidly developed. These features are beyond the scope of this report, and the reader is referred to several recent reviews.

Why discuss acquired immunodeficiency syndrome (AIDS) in “Topics in Long-Term Care”? It is not because there are large numbers of frail elderly patients afflicted with AIDS, although some have estimated that by 1990 there may be as many as 27,000 AIDS cases in persons over 50, and 1,100 cases in persons over 70 years of age. Nor is it the fact that large numbers of patients in long-term care facilities (LTCFs) may be infected with the human immunodeficiency virus HIV). Rather, it is the growing awareness that hospitals provide only a limited portion of the continuum of care for AIDS patients. In addition, the chronically ill and often severely disabled AIDS patient frequently requires more care than the limited community-based resources can provide. Nursing homes, with their tradition of skilled nursing care targeted toward the chronically ill and older patient, could provide an important missing component to the chronic care needs of younger AIDS patients.

Persons age 65 and over constitute the largest reservoir of Mycobacterium tuberculosis infection in the United States today. During 1987, 6,150 tuberculosis cases were reported among this high-risk group. These cases represent 27% of the total US tuberculosis morbidity, although this age group constitutes only 12% of the US population. Tuberculosis case rates in the United States are higher among the elderly (20.6 per 100,000) than among all other age groups (average 9.3 per 100,000).
More Americans live in nursing homes than in any other type of residential institution; on any given day approximately 5% of all elderly persons are living in a nursing home. Elderly nursing home residents are at greater risk for tuberculosis than elderly persons living in the community. In a Centers for Disease Control (CDC)-sponsored survey of 15,379 routinely-reported tuberculosis cases from 29 states, 8% of the 4,919 cases that occurred among elderly persons occurred among residents of nursing homes. The incidence of tuberculosis among nursing home residents was 39.2 per 100,000 person years, whereas the incidence of tuberculosis among elderly persons living in the community was 21.5 per 100,000. The observed rate of tuberculosis among nursing home employees was three times the rate expected in employed adults of similar age, race and sex (CDC, unpublished data).

This article is the first in a new series entitled “Topics in Long-Term Care.” The author, a full-time academic physician, is based at a chronic disease hospital with a 577-bed nursing home where he is head of infectious diseases and, with the support of a full-time infection control officer (RN), manages the infection control programs as the hospital epidemiologist and chair of the infection control committee. Although most interest centers on the nursing home setting, the title reflects the need to consider all long-term care facilities (LTCFs) with special populations and risk factors for acquiring infection, e.g., rehabilitation units, day care centers and day hospitals for the elderly and institutions for developmental disabled persons of all ages.
