Infections and antibiotic prescribing in Swedish nursing homes: a cross-sectional study

The aim of this study was to present and assess the treatment of infections in Swedish nursing homes. It included 58 nursing homes with 3002 residents. During 3 months, nurses in the nursing homes recorded all infections requiring a physician's opinion. Of the 889 infectious episodes, 84% were treated with antibiotics. Many of the antibiotics were issued after indirect contact with the physician (38%). Indications for antibiotics were in 55% of the cases urinary tract infections (UTI), in 17% skin and soft-tissue infections and in 15% respiratory tract infections (RTI). The most common antibiotics were penicillins (38%), followed by quinolones (23%) and trimethoprim (18%). For the major indication, lower UTI in women, half of the cases were not treated according to the recommendations. The main concerns were length of treatment and overprescribing of quinolones. For the second major diagnosis, pneumonia, the high use of doxycycline could be questioned. Continuing education on infections and their treatment in nursing homes is needed. Training should preferably include both physicians and nurses as a high proportion of antibiotics is issued without direct contact with the physician.     

UTI: managing the most common nursing home infection

Urinary tract infections (UTIs) are the most common type of infection in nursing homes. Asymptomatic bacteriuria, the most common form, requires no treatment. Symptomatic UTI requires treatment, but symptoms (acute deterioration in functional ability or mental status) may be nonspecific. Complicated UTI is more common in nursing home residents than in other populations. Immobility and the use of bedpans instead of commodes contribute to decreased bladder emptying and an increased potential for UTI. Poor perineal hygiene in many females in nursing homes also increases the potential for UTI. For this reason, obtaining urine for culture by catheterization rather than voided specimen should be the norm for female nursing home 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.     

A survey of hypnotic use in geriatric institutions in Sogn og Fjordane, Norway.

We investigated the use of hypnotics in nursing homes and old age homes in the county of Sogn og Fjordane, Norway. Data on administration of hypnotics on 3 separate days within a week in August 1995 was obtained from the drug administration records in 31 institutions. Twenty-five percent of the 1062 patients in the institutions used hypnotics, with no difference between patients from nursing homes and old age homes. The number of patients treated with hypnotics, the doses administered, and the time of administration were similar for weekends and workdays. About 100% of the hypnotics were used as scheduled, and 29% of the doses administered were higher than the recommended lowest dose for elderly patients. Furthermore, about 50% of the hypnotics administered were long-acting benzodiazepines. The results indicate a need for a review of the prescribing of hypnotics in geriatric institutions.     

Is There Significant Regional Variation in Hospital Antibiotic Consumption in Germany?

Abstract Objective: Outpatient antibiotic use in Germany differs substantially between eastern and southern parts of the country (low use) and the western part (high use). Whether similar regional variation exists in hospital antibiotic consumption is not known. We investigated this issue using a convenience sample of 145 hospitals providing data for the year 2003. Methods: Data on hospital consumption of systemic antibiotics in Anatomical Therapeutic Chemical (ATC) class J01 were obtained from acute care hospitals that participated in an IMS survey and had complete data (dispensed drugs and patient-days per year) for at least one non-pediatric, non-psychiatric department or ward. A total of 275 non-ICU surgical departments/wards, 229 non-ICU non-surgical (general medicine, haematology-oncology, neurology/stroke) departments/wards, and 184 ICUs were analysed. Data were expressed in DDD (WHO/ATC definition version 2003) or daily doses adapted for recommendations in hospitalized patients (RDD) per 100 patient days (DDD/100 and RDD/100). Findings: The weighted mean over all departments/wards was 49.6 DDD/100 or 31.3 RDD/100, respectively. As expected, ICU antibiotic use density was much higher than use in non-ICU areas, and use in haematology–oncology was higher than in other non-surgical departments/wards. In univariate analyses, region, hospital bed-size category, university affiliation and haematology-oncology as specialty were associated with use density, but these associations were only partly confirmed in multivariate logistic regression analyses of factors associated with excess (≥ 75%) use density which showed university affiliation and haematology-oncology but not hospital location to be independently associated with comparatively high use. Conclusions: Antibiotic use density in German acute care hospitals does not appear to differ significantly between regions. Overall hospital consumption of antibiotics in this country appears to be similar to what has been described from other parts of Europe. In comparative analyses of hospital antibiotic consumption, data need to be adjusted at least for university affiliation and haematology-oncology.     

Purple urine bag syndrome in nursing homes: Ten elderly case reports and a literature review

Purple urine bag syndrome (PUBS) is a rare occurrence, in which the patient has a purple-colored urine bag following urinary catheterization for hours to days. Most of authors believe it is a mixture of indigo (blue) and indirubin (red) that becomes purple. Previous study showed that PUBS occurred predominantly in chronically catheterized, constipated women. We collected 10 elderly patients with PUBS in two nursing homes. The first two cases were identified by chart review in 1987 and 2003, and then later eight cases (42.1%) were collected among 19 urinary catheterized elderly in the period between January 2007 and June 2007. In the present report, PUBS probably can occur in any patients with the right elements, namely urinary tract infection (UTI) with bacteria possessing these enzymes, diet with enough tryptophan, and being catheterized. Associations with bed-bound state, Alzheimer’s, or dementia from other causes are reflections of the state of such patients who are at higher risk for UTI, and hence PUBS occurred. Although we presented PUBS as a harmless problem, prevention and control of the nosocomial catheter-associated UTIs (CAUTIs) has become very important in the new patient-centered medical era. Thus, we should decrease the duration of catheterization, improve catheter care, and deploy technological advances designed for prevention, especially in the elderly cared for in nursing homes.     

Intake of Drugs among Elderly People in a Danish Municipality,Rødovre

ABSTRACT. Drug intake has been studied among a random group of persons, aged 75 or over, in Rødovre Municipality. Two hundred and eighty-three elderly persons living in their own homes have been visited and interviewed about their daily intake of prescribed and non-prescribed drugs (including so-called natural drugs). Similar information was gathered from 146 elderly persons living in nursing homes. Thirty-one per cent of the elderly living in their own homes and 3% of those living in nursing homes did not use prescribed drugs daily. The median daily amount of different types of drugs used was 1.8 (range 0–10) for elderly persons living in their own homes and 4.5 (range 0–11) (p<0.001) for those living in nursing homes. Women living at home had a higher intake of drugs than men, especially diuretics. The most frequently used drugs were diuretics, sedatives/hypnotics, analgesics, digitalis and electrolytes. For all types of drugs a higher consumption, especially of phenothiazines, was found among elderly persons living in nursing homes. Drug consumption was independent of age and social stratification in both groups. The use of non-prescribed drugs ranges from 0 to 9 different types in the group living in their own homes, and from 0 to 5 in the group living in nursing homes—laxatives being the type most frequently used.     

Measuring the quality of urinary continence care in long-term care facilities: an analysis of outcome indicators

BACKGROUND: the National Centre for Health Outcomes Development has produced outcome indicators for the assessment of quality of care in the management of urinary incontinence. Three measures relate to the management of older people in long-term care: the prevalence of incontinence, the use of indwelling catheters and clinical assessment rates. OBJECTIVE: to evaluate the recommended outcome measures in clinical practice. METHOD: participating centres included residential homes, nursing homes and long-stay wards. We sent a structured questionnaire to each centre for qualitative assessment of the acceptability of the outcome indicators. We analysed data collected by nurses and other staff who used the urinary incontinence section of the Royal College of Physicians Continuous Assessment Review and Evaluation scheme audit tool for long-term care. RESULTS: there were 1125 residents in 17 residential homes, 14 nursing homes and five long-stay wards. The overall prevalence of urinary incontinence was 34% in residential homes (range 2-86%), 70% in nursing homes (38-100%) and 71% in long-stay wards (4-97%). Catheterization rates were 5% in residential homes (0-20%), 10% in nursing homes (0-44%) and 6% in long-stay wards (0-20%). Rates of full clinical assessment were 48, 24 and 36% respectively. CONCLUSION: there is great variability in these outcome measures within and between settings. Interpretation of outcome results requires more precise details on case-mix and the definition of outcome measures. Individual units found the audit tool helpful, but we advise caution with interpretation of outcomes between units.     

Diagnostic accuracy of criteria for urinary tract infection in a cohort of nursing home residents

OBJECTIVES: To prospectively evaluate nursing home residents with suspected urinary tract infection (UTI) to determine whether they met the McGeer, Loeb, or revised Loeb consensus-based criteria and whether any set of criteria was associated with laboratory evidence of UTI, namely bacteriuria (>100,000 colony forming units) plus pyuria (>10 white blood cells). DESIGN: Prospective cohort study. SETTING: Three New Haven-area nursing homes. PARTICIPANTS: Of 611 residents screened, 457 were eligible, 362 consented, and 340 enrolled. MEASUREMENTS: Participants underwent prospective surveillance from May 2005 to April 2006 for the development of suspected UTI (defined as a participant's physician or nurse clinically suspecting UTI). One hundred participants with suspected UTI and a urinalysis and urine culture performed were included in the analyses. RESULTS: Participants were identified who met the criteria of McGeer, Loeb, revised Loeb, and laboratory evidence of UTI. Using laboratory evidence of UTI as the outcome, the McGeer criteria demonstrated 30% sensitivity, 82% specificity, 57% positive predictive value (PPV), and 61% negative predictive value (NPV); the Loeb criteria showed 19% sensitivity, 89% specificity, 57% PPV, and 59% NPV; and the revised Loeb criteria demonstrated 30% sensitivity, 79% specificity, 52% PPV, and 60% NPV. CONCLUSION: All of the consensus-based criteria have similar test characteristics. The diagnostic accuracy of UTI criteria in nursing home residents could be improved, and the data suggest that evidence-based clinical criteria associated with laboratory evidence of UTI need to be identified and validated.     

Quantitative Antibiotic Use in Hospitals: Comparison of Measurements, Literature Review, and Recommendations for a Standard of Reporting

Background  Reports on antibiotic use often lack complete definitions of the units of measurement, hampering the comparison of data between hospitals or hospital units. Methods  To compare methods of measures of in-hospital antimicrobial use, we determined aggregate in-hospital consumption data at a tertiary care university hospital using variations of nominators and denominators. Means of defined daily doses (DDD) of individual antimicrobials per 100 bed-days and per 100 admissions at each hospital and intensive care unit (ICU) were calculated. Furthermore, a literature review was performed for benchmarking purposes. Results  Antibiotic use in different hospital units ranged from 0.105 to 323.37 DDD/100 bed-days and from 4.23 to 6737.92 DDD/100 admissions, respectively. Including the day of discharge in the denominator ‘bed-days’ underestimated antibiotic use in various hospital wards by up to 27.7 DDD/100 bed-days (26.0%). Equating ‘numbers of patients admitted to the hospital’ and ‘numbers of admissions’ on a hospital level resulted in a difference of 192.6 DDD/100 admissions (64%) because patients transferred between hospital units accounted for multiple admissions. Likewise, reporting antimicrobial (Anatomical Therapeutic Chemical [ATC] group ‘J’) instead of antibiotic (ATC group ‘J01’) use led to a difference of 16.5 DDD/100 bed-days (19.3%). The literature review revealed underreporting of complete definitions of antibiotic use measurements. Conclusions  Data on in-hospital antimicrobial use vary widely not only due to different antibiotic policies at different institutions but also due to different methods of measures. Adherence to the standard of reporting the methods of measurement is warranted for benchmarking and promotion of rational antimicrobial use.     

Antibiotic consumption at 46 VINCat hospitals from 2007 to 2009, stratified by hospital size and clinical services

The aim of the study was to assess the evolution of antibiotic consumption in acute care hospitals in Catalonia (population 7.5 million), according to hospital size and department, during the period 2007-2009. The methodology used for monitoring antibiotic consumption was the ATC/DDD system, and the unit of measurement was DDD/100 occupied bed-days (DDD/100 OBD). Hospitals were stratified according to size: I) large university hospitals (with more than 500 beds); II) medium-sized hospitals (between 200 and 500 beds); and III) small hospitals (fewer than 200 beds). The consumption was also analyzed and stratified according to department: medical, surgical and intensive care unit (ICU). Specific training in data management on antibiotic consumption was given to all participant hospitals before the implementation of the program. The mean antibiotic (J01) consumption, calculated in DDD/100 OBD, increased although without statistical significance (p=0.640): 74.68 (2007), 75.13 (2008) and 78.04 (2009). The values of the medians expressed in DDD/100 OBD in group I were 83.27 (in 2007), 82.16 (2008) and 86.93 (2009), in group II 72.60 (2007), 70.78 (2008) and 75.17 (2009) and in group III 65.66 (2007), 69.32 (2008) and 72.39 (2009). Antibiotic consumption was higher in large hospitals than in medium-sized or small hospitals. Catalan hospitals recorded an increase of 4.49% from 2007 to 2009, especially due to the rising use of carbapenems, cephalosporins, monobactams and the other antibiotic groups.     

Application of Laboratory Research in UTI

With the development of molecular biology, new techniques in urinary tract infection (UTI) research have been introduced. This article reports on study models, molecular techniques and genetic engineering presently used in studies on UTI pathogenesis. Recent research is reviewed, and molecular bacterial virulence mechanisms and the role of inflammation in the antibacterial defenses are discussed. Pivotal studies are presented in more detail to demonstrate the use of the new methods: the in vivo investigation of bacterial virulence factors and host interaction in a human colonization protocol; the experimental mouse UTI model where mice strains differing in genetics demonstrate selective dysfunctions; the search for human polymorphism explaining suceptibility to infectious diseases.     

Between-country variation in the utilization of antihypertensive agents: Guidelines and clinical practice

Variation in antihypertensive drug utilization and guideline preferences between six European countries (Denmark, Finland, Germany, Norway, Sweden, the Netherlands) was investigated. Our objectives were to compare between-country variability in utilization per class of antihypertensive agents and to assess guideline preferences in relation to actual use. Antihypertensive consumption data (2003) was retrieved. We classified antihypertensive agents using ATC-codes: C02CA - alpha-blockers (AB), C03A - thiazide diuretics (TD), C07AB - beta-blockers (BB), C08CA - dihydropyridine calcium antagonists (CA), C09A/C09BA/C09BB - ACE-inhibitors+combinations (AI) and C09C/C09D - angiotensin II receptor blockers+combinations (AT2). For each class, DDDs/1000 persons/day and share (%) of total antihypertensive utilization was calculated. Per class, relative standard deviations (RSD) across countries were computed. Current hypertension guidelines were requested from national medical associations. Total antihypertensive utilization varied considerably, ranging from 152.4 (Netherlands) to 246.9 (Germany) DDDs/1000 persons/day. RSD was highest for TD (106.2%) and AB (93.6%). Where guidelines advocated TDs (Norway and Netherlands), TD utilization was below (Norway) or just above (Netherlands) median TD use. Guidelines recommended TD (Norway and Netherlands), TD/BB/AI (Finland, German Physicians Association) or TD/BB/CA/AI/AT2 (Denmark, German Hypertension Society), Sweden had no recent national guideline. In conclusion, antihypertensive utilization patterns varied largely across these six countries, in absolute and relative terms. Furthermore, guidelines seem disconnected from clinical practice in some countries, and none of the guidelines discuss current utilization. Whether this reflects a need for change in prescribing or re-evaluation of guidelines warrants further research.     

Nursing home practitioner survey of diagnostic criteria for urinary tract infections

OBJECTIVES: To identify clinical and laboratory criteria used by nursing home practitioners for diagnosis and treatment of urinary tract infections (UTIs) in nursing home residents. To determine practitioner knowledge of the most commonly used consensus criteria (i.e., McGeer criteria) for UTIs. DESIGN: Self-administered survey. SETTING: Three New Haven-area nursing homes. PARTICIPANTS: Physicians (n=25), physician assistants (PAs, n=3), directors/assistant directors of nursing (n=8), charge nurses (n=37), and infection control practitioners (n=3). MEASUREMENTS: Open- and closed-ended questions. RESULTS: Nineteen physicians, three PAs, and 41 nurses completed 63 of 76 (83%) surveys. The five most commonly reported triggers for suspecting UTI in noncatheterized residents were change in mental status (57/63, 90%), fever (48/63, 76%), change in voiding pattern (44/63, 70%), dysuria (41/63, 65%), and change in character of urine (37/63, 59%). Asked to identify their first diagnostic step in the evaluation of UTIs, 48% (30/63) said urinary dipstick analysis, and 40% (25/63) said urinalysis and urine culture. Fourteen of 22 (64%) physicians and PAs versus 40 of 40 (100%) nurses were aware of the McGeer criteria for noncatheterized patients (P<.001); 12 of 22 (55%) physicians and PAs versus 38 of 39 (97%) nurses used them in clinical practice (P<.001). CONCLUSION: Although surveillance and treatment consensus criteria have been developed, there are no universally accepted diagnostic criteria. This survey demonstrated a distinction between surveillance criteria and criteria practitioners used in clinical practice. Prospective data are needed to develop evidence-based clinical and laboratory criteria of UTIs in nursing home residents that can be used to identify prospectively tested treatment and prevention strategies.     

Influenza outbreak detection and control measures in nursing homes in the United States

OBJECTIVE: To evaluate the use of influenza vaccine, rapid influenza testing, and influenza antiviral medication in nursing homes in the US to prevent and control outbreaks. METHODS: Survey questionnaires were sent to 1017 randomly selected nursing homes in nine states. Information was collected on influenza prevention, detection and control practices, and on outbreaks during three influenza seasons (1995-1998). RESULTS: The survey response rate was 78%. Influenza vaccine was offered to residents and staff by 99% and 86%, respectively, of nursing homes. Among nursing homes offering the influenza vaccine, the average vaccination rate was 83% for residents and 46% for staff. Sixty-seven percent of the nursing homes reported having access to laboratories with rapid antigen testing capabilities, and 19% reported having a written policy for the use of influenza antiviral medications for outbreak control. Nursing homes from New York, where organized education programs on influenza detection and control have been conducted for many years, were more likely to have reported a suspected or laboratory-confirmed influenza outbreak (51% vs 10%, P = .01), to have access to rapid antigen testing for influenza (92% vs 63%, P = .01), and to use antivirals for prophylaxis and treatment of influenza A for their nursing home residents (94% vs 55%, P = .01) compared with nursing homes from the other eight states. CONCLUSIONS: Influenza outbreaks among nursing home residents can lead to substantial morbidity and mortality when prevention measures are not rapidly instituted. However, many nursing homes in this survey were neither prepared to detect nor to control influenza A outbreaks. Targeted, sustained educational efforts can improve the detection and control of outbreaks in nursing homes.     

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.
