Restraint use among nursing home residents: cross‐sectional study and prospective cohort study

To investigate (1) the prevalence of physical restraints and psychoactive medication, (2) newly administered physical restraints, frequency of application of the devices and frequency of psychoactive medication on demand during 12-month follow-up and (3) characteristics associated with restraint use in nursing homes. High quality data on restraint use in German nursing homes are lacking so far. Such information is the basis for interventions to achieve a restraint-free care. Cross-sectional study and prospective cohort study. Thirty nursing homes with 2367 residents in Hamburg, Germany. External investigators obtained prevalence of physical restraints by direct observation on three occasions on one day, psychoactive drugs were extracted from residents' records and prospective data were documented by nurses. Residents' mean age was 86 years, 81% were female. Prevalence of residents with at least one physical restraint was 26.2% [95% confidence interval (CI) 21.3-31.1]. Centre prevalence ranged from 4.4 to 58.9%. Bedrails were most often used (in 24.5% of residents), fixed tables, belts and other restraints were rare. Prevalence of residents with at least one psychoactive drug was 52.4% (95% CI 48.7-56.1). The proportion of residents with at least one physical restraint after the first observation week of 26.3% (21.3-31.3) cumulated to 39.5% (33.3-45.7) at the end of follow-up (10.4 SD 3.3 months). The relative frequency of observation days with at least one device ranged from 4.9-64.8% between centres. No characteristic was found to explain centre differences. The frequency of physical restraints and psychoactive drugs in German nursing homes is substantial. Pronounced centre variation suggests that standard care is possible without restraints. Effective restraint minimisation approaches are urgently warranted. An evidence-based guideline may overcome centre differences towards a restraint-free nursing home care.

Hypoglycaemia in residential care homes

Hypoglycaemia is the most common metabolic complication occurring in older people with type 2 diabetes. Limited data are available about prevalence of diabetes or its complications in care homes. However, the prevalence of residents with diabetes in care homes seems to be significant. There is high level of disability, dependency, and polypharmacy among residents in these settings. Hypoglycaemia is both an important adverse reaction of treatment and an outcome measure. This study reviews the relevant literature and reports a case of hypoglycaemia to demonstrate the causes of hypoglycaemia, characteristics of these patients, and the complexity of their problems.

Determinants of cockroach and mouse exposure and associations with asthma in families and elderly individuals living in New York City public housing

Asthma prevalence is high in the inner city, and morbidity has been associated with cockroach and mouse allergens. To characterize the relationships among pests, allergens, pesticides, and asthma in New York City public housing. In 324 apartments, dust samples collected from beds and kitchens were analyzed for cockroach (Bla g 2) and mouse (mouse urinary protein [MUP]) allergens, pest populations were monitored, and residents were interviewed about home characteristics and asthma symptoms. Cockroaches were found in 77% of the apartments, and evidence of mice was found in 13%. Allergens and pesticide use were associated with pest infestation, and 15% of residents reported using illegal pesticides. The percentage of apartments with high allergen levels varied significantly by building (Bla g 2: P = .002; MUP: P = .03), as did the percentage of apartments with cockroaches (P = .002) and daily mouse sightings (P = .02). Thirty-seven percent of the apartments had at least 1 resident with physician-diagnosed asthma. In family buildings, apartments with high Bla g 2 levels had 1.7 times greater odds of having an asthmatic resident (95% confidence interval, 1.2-2.3). In senior citizen buildings, apartments with high MUP levels had 6.6 times greater odds of having an asthmatic resident (95% confidence interval, 1.4-31.7), controlling for smoking and other potential confounders. Previous studies have identified home characteristics associated with the presence of cockroaches and mice, but the present findings suggest that building-level characteristics can affect high pest exposure. Furthermore, the high asthma prevalence in residents and the use of illegal pesticides highlight the need for safe and effective building-wide pest control strategies.

Prevalence of soil transmitted nematodes on Nukufetau, a remote Pacific island in Tuvalu

BackgroundThe population of Nukufetau, a remote coral atoll island in Tuvalu in the Western Pacific, received annual mass drug administration (MDA) of diethylcarbamazine and albendazole under the Pacific Elimination of Lymphatic Filariasis program in 2001, 2002 and 2003, with the last MDA occurring six months before a cross-sectional survey of the whole population for soil transmitted helminths (STH).MethodsA cross-sectional survey in May 2004 recruited 206 residents (35.2% of the population) who provided a single faecal sample that was preserved, concentrated and examined microscopically.ResultsOverall prevalence of STH was 69.9%; only hookworm and Trichuris trichiura were diagnosed. Trichuris was present in 68.4% with intensity of infection being light in 56.3%, medium in 11.7% and heavy in 0.5%. Hookworm occurred in 11.7% with intensity of infection 11.2% being light and medium in 0.5%. Twenty individuals (9.7%) had dual infections. The prevalence of Trichuris was constant across all ages while the prevalence of hookworm was significantly lower in residents below 30 years of age. In the age group 5–12 years comparison of results with a 2001 survey [1] suggested that the prevalence of STH has declined minimally, due to sustained high prevalence of Trichuris, while hookworm has declined dramatically from 34.4% to 1.6%.ConclusionThe results of this survey suggest that although the MDA appears to have reduced hookworm prevalence in residents below 30 years of age, there has been minimal effect on Trichuris prevalence. An integrated program to control STH is required.

Survey of Long-Term-Care Facilities in Iowa for Policies and Practices Regarding Residents With Methicillin-Resistant Staphylococcus aureus or Vancomycin-Resistant Enterococci

To identify infection control policies and practices used by long-term-care facilities (LTCFs) in Iowa for residents with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant enterococci (VRE), and to estimate the prevalence of residents known to have these organisms. Survey. LTCFs in Iowa from December 2002 through March 2003. Of the 429 LTCFs in Iowa, 331 (77%) responded to the survey. The estimated prevalence of residents known to have MRSA was 13.4 per 1,000 and that of residents known to have VRE was 2.3 per 1,000. Facilities owned by the government or those with an average of more than 86 occupied beds were more likely to have residents known to have MRSA and VRE (P = .002 and .007, respectively). Of the responding facilities, 7.3% acknowledged that they refused to accept individuals known to have MRSA and 16.9% acknowledged that they refused to accept those known to have VRE. Facilities in large communities (population, > 100,000) were least likely to deny admission to an individual known to have either MRSA or VRE (P = .05). Most facilities reported adhering to the national guidelines, but fewer than half (44.7%) of the respondents had heard of the Iowa Antibiotic Resistance Task Force's guidelines regarding residents with MRSA or VRE. Many LTCFs in Iowa care for residents known to have MRSA or VRE, but some refuse to admit these individuals. Infection control personnel and public health officials should work together to educate LTCF staff so that residents receive proper care and resistant organisms do not spread within this setting.

A national study showed that diagnoses varied by age group in nursing home residents under age 65

Objective Those aged <65 in nursing homes (NHs) are substantially different from elderly residents. This study uses data gathered from the Resident Assessment Instrument's Minimum Data Set (MDS) to describe these relatively rare residents. Study design and setting The study uses MDS assessments of close to three-quarter million residents in nine states from 1994 to 1996. Residents are described within chronological age group (0–4, 5–14, etc.). Factor analysis is used to develop diagnostic clusters, and the prevalence of these clusters, functional problems, other conditions, and treatments is described for each group. Results Thirteen diagnostic clusters describe nearly 85% of all NH residents and highlight differences between age groups. Pediatric residents are substantially more physically and cognitively impaired than young adult residents, and have the highest case mix burden of care. The youngest population primarily has diagnoses related to mental retardation and developmental disabilities, young adults have the highest prevalence of hemi- and quadriplegia, while older residents are typified by increasing prevalence of neurological diagnoses. Conclusion This study offers an initial description of NH residents <65. The prevalence of residents with unique conditions may suggest the need to modify the MDS assessment instrument.

Joint pain and swelling prevalence in residents of different regions of Russian Federation (preliminary results)

Objective. To reveal in a population sample people with joint pain and swelling. Material and methods. A screening questionnaire for revelation arthritis and arthralgia was filled for each adult resident of 18 years or older. Screening examination was performed in country and city samples. Universal examination was performed among country residents, representative sample was formed for city residents. Results. 23438 residents were screened, mean age was 48,1 ±17,6 years. Women were prevalent - 60%. 8016 were city and 15422 - country residents. Joint pain prevalence was 45%, joint swelling - 27%. These symptoms disappeared with time in 7% and 6% respectively. In other people they became chronic. Population prevalence of joint complaints is connected with sex and depends on age. In people younger than 20 years of age prevalence of joint pain was 9% and swelling - 3%. Conclusion. Preliminary analysis of the screening part of the study showed scale of the joint pathology problem and allowed to get the first data on prevalence of arthralgia and arthritis in Russia.

Hepatitis C in a community in Upper Egypt: I. Cross-sectional survey.

The prevalence of antibody to hepatitis C virus (anti-HCV) was determined in a cross-sectional survey in a village in Upper Egypt. Exposure and demographic characteristics were obtained through a questionnaire. Antibody to hepatitis C virus was assessed using a second generation enzyme immunoassay, and the presence of HCV RNA was tested using a reverse transcriptase-polymerase chain reaction. Collection of blood samples was targeted at those > or = 5 years old, and obtained from 62.8%. This report describes the community, the HCV infection characteristics of the subjects, and evaluates some factors associated with presence of anti-HCV. Of the 6,031 participants, 522 (8.7%) were anti-HCV positive. Prevalence was higher among males than females (11.3% versus 6.5%; P < 0.001). It was greater among those > 30 years of age than among those < or = 30 years of age (20.0% versus 3.6%; P < 0.001). Those who were less educated, farmed, provided health care, and were currently married had a significantly higher anti-HCV prevalence than those who were not; however, these associations were not significant after adjusting for age. Although active infections with Schistosoma haematobium were not associated with anti-HCV, a history of past infection was (age-adjusted risk ratio [RR] = 2.1, 95% confidence interval [CI] = 1.8, 2.4); 134 persons who had a history of receiving parenteral anti-schistosomal therapy had a higher age-adjusted RR (3.0; 95% CI = 2.5, 3.7) for anti-HCV than those who did not. Hepatitis C virus RNA was detected in 62.8% of the anti-HCV positive subjects, without significant variation by age, gender, education, or marital status. The prevalence of anti-HCV in Upper Egypt is high, albeit lower than in Lower Egypt, with continuing but limited transmission indicated by the lower prevalence in residents < or = 30 years old.

GB virus-C/hepatitis G virus infection in a hepatitis C virus endemic village: prevalence in residents with low educational attainment and frequent recovery in females.

GB virus-C/hepatitis G virus (HGV) is a newly identified flavivirus, which may share the same mode of transmission as hepatitis C virus (HCV). The aim of this study was to investigate associated factors of HGV infection and clearance in a HCV endemic village in southern Taiwan. Five hundred and ninety-four residents of a village in southern Taiwan were enrolled for hepatitis virus screening. Clinical features were recorded and a questionnaire addressing the possible routes of transmission was filled in by the participating residents. The prevalence of antibody to hepatitis C virus and hepatitis B surface antigen in the 594 residents was 70.7% and 19.5% respectively. Of the 399 residents tested for HGV RNA, GB virus-C/Hepatitis G virus envelop 2 protein (HGV-E2) antibody, and HCV RNA, the prevalence was 13.5%, 25.3%, 53.1% respectively. Multivariate logistic regression analysis showed that low educational attainment was associated with HGV infection, old age and low educational attainment were associated with HCV infection, and female gender was associated with HGV clearance. Alanine aminotransferase (ALT) values were significantly higher for residents with HCV infection alone, HBV infection alone, and co-infection of HCV and HBV than for those without HBV, HCV, and HGV infection. There were no differences in ALT values between subjects with HGV infection alone and those without HBV, HCV, and HGV infections. Residents with co-infection of HGV and HBV, or HGV and HCV had ALT values similar to those with HBV or HCV infection alone. HGV infection is common in the HCV endemic village. The transmission of HGV is closely related to low educational attainment. HGV clearance is frequently encountered in females. Co-infection of HGV does not compound hepatocellular inflammation.

Methicillin-resistant Staphylococcus aureus: a questionnaire and microbiological survey of nursing and residential homes in barking, havering and brentwood

The study determined the policies and procedures for the control and prevention of methicillin-resistant Staphylococcus aureus (MRSA) and its prevalence among nursing and residential homes, and evaluated whether certain home characteristics such as bed size, staffing level, and type of home are related to the prevalence of MRSA. A 21-questionnaire survey, with primarily categorical responses, was mailed to the home managers of all the 121 nursing and residential homes in the district, following which a simple, stratified random sample of 28 (23.14%) homes was taken and all agreeing residents screened from multiple sites for MRSA. Seventy-seven (63.6%) homes returned a completed questionnaire, 13 (46.4%) of whom agreed to participate in the microbiological study. The response rates for returning questionnaires and agreeing to participate in the microbiological study were similar for nursing and residential homes (65% vs. 60%; 67% vs. 40%; P = 0.12; P = 0.62), respectively. Nursing homes had a mean bed size of 30 (95% Confidence Interval (CI) 17-43), not significantly different from residential homes of 23 (95% CI 18-27; P = 0.26). The nursing homes employed a mean of 8.6 (95% CI 4.7-12.5) staff nurses per home; significantly higher than residential homes with a mean of 1.6 (95% CI 0.3-2.8; P = 0.006). No significant differences in mean number of home care assistants employed per home (22.8; 95% CI 12.4-33.13; and 14.4; 95% CI 11.83-16.90; P = 0.098, for nursing and residential homes, respectively) were observed. None of the homes had employed infection control practitioners. Only four (6.8%) of the responding homes stated that MRSA was a problem. Nursing homes were not significantly more likely to have admission policies for colonized person than residential homes (10/13 vs. 40/55, P = 1.00). Of the fifty-five (71.4%) homes who had admission policies, 40 (72.7%) stated that persons colonized/infected with MRSA would not be accepted, while 12 (21.8%) would accept such persons in single-room isolation and/or barrier nursing. Greater proportions of residential homes than nursing homes would not accept admission of persons with documented MRSA colonization (30/35 vs. 4/10, P = 0.007). Four (9.1%) homes (three nursing) had identified a total of five residents colonized/infected with MRSA in 5 years prior to the survey. Two hundred and forty-six residents were screened (552 sites), two (0.81%) of whom were found to be colonized in the nose (one resident) and in the groin (two residents) with MRSA, giving a 2-month weighted point prevalence rate of 0.14% (95% CI 0.01-0.26%). We conclude that in our district the nursing staffing levels and control measures vary widely within these homes, while the prevalence of residents who are colonized/infected with MRSA is lower than in other areas. We suggest that the exclusion admission policy for MRSA positive patients should be abandoned and targeted infection control programmes be instituted.

Symptom Prevalence and Worry about High Voltage Transmission Lines

Few studies have documented public perceptions of environmental health risks from exposure to overhead transmission lines. In particular, little information has been provided on the impact of worry on symptom prevalence in residents living adjacent to high voltage transmission lines. The current study assessed symptom prevalence and worry in 152 Orange County female residents living either adjacent to overhead transmission lines or one block away. Forty-five percent of the respondents were either very worried or somewhat worried about the transmission lines and 55% were slightly worried or not worried at all. Results indicated that for those who did not live on the easement level of worry did not affect the prevalence of health problems, For those who lived on the easement, the most worried respondents were more likely to report health problems. Disclosure of health problems may depend more on individuals′ level of worry about rather than proximity to overhead transmission lines. Possible limitations of this study include personality variables such as hypochondriasis which were not assessed, recall bias, and social desirability, The homogeneity of subjects may also limit the generalizability of findings.

The feasibility and value of using patient satisfaction ratings to evaluate internal medicine residents

To determine the feasibility and value of using patient satisfaction ratings to evaluate the physician-patient relationship skills of medical residents. A cross-sectional survey was used to collect patient satisfaction information for medical residents from all patients attending the out-patient teaching clinics over a three-month period. The feasibility of patient rating was assessed by evaluating the reliability of resident satisfaction scores and potential sources of bias in rating. The value of using this method was assessed by evaluating the proportion of variance in ratings attributable to residents, the prevalence of residents with ratings substantially below average, and the effect of training on patient satisfaction. The medical clinics of two teaching hospitals at McGill University. 91 medical residents and clinical clerks, 1,003 patients, and 1,219 visit ratings. An average of 12.2 satisfaction ratings were collected per resident, providing a reliability of 0.56 (intraclass correlation) for resident satisfaction score. Adjustment for differences in patient populations would be necessary to obtain comparable scores among residents. Fifteen percent of the residents had a substantially greater proportion of poor and fair satisfaction ratings than the study average. Residents were responsible for a substantial proportion of the variance in clinic waiting time and patient satisfaction rating. Training appeared to have no effect on improving satisfaction scores, except among women residents. Patient satisfaction ratings provide valuable information about a resident's ability to establish an effective physician-patient relationship. However, the number of ratings required to obtain a reliable estimate of resident skill may limit the feasibility of using patient ratings as part of residency evaluation.
