The role of selective decontamination of the digestive tract in acute stroke.

BACKGROUND: following a stroke, morbidity and mortality is high, with aspiration pneumonia being a common complication. OBJECTIVES: to determine the levels of colonisation by and isolation of aerobic Gram-negative bacteria (AGNB) in acute stroke patients and determine the effect of selective decontamination of the digestive tract (SDD) on oral flora and whether it reduces both morbidity and mortality after an acute stroke. DESIGN: a prospective, randomised, placebo-controlled double blind trial. SETTING: acute stroke assessment units of three hospitals in the northwest of England. SUBJECTS: 203 patients admitted to hospital following a first acute stroke. METHODS: participants were randomised to SDD oral gel or placebo. Swallow was assessed on admission to hospital, and oral swabs were obtained thrice weekly. Demographic and clinical data were recorded. RESULTS: 203 patients (106 males and 97 females) participated, of whom 20 died during their hospitalisation, 19 withdrew and full follow-up was obtained for the remaining 164. A total of 122 AGNB were isolated in 105 samples from 48 patients. Abnormal swallow on admission was found in 58 patients (29%). A total of 34 patients carried a single gram-negative micro-organism that was present on one or more occasions. More than one AGNB was carried in 14 patients, and organisms were significantly more likely to be isolated from the placebo group than the active group during weeks 2 and 3 of treatment (P = 0.034, chi-squared). Seven patients in the placebo group and one in the treatment group developed pneumonia (P = 0.029, Fisher's exact test). CONCLUSIONS: high carriage of and colonisation by AGNB was found within this study, which was reduced by the addition of SDD. Although SDD reduced the presence of both organisms and documented episodes of pneumonia, mortality remained unchanged.

Cost-benefit evaluation of routine influenza immunisation in people 65-74 years of age.

OBJECTIVES: To determine the cost-effectiveness of influenza vaccination in people aged 65-74 years in the absence of co-morbidity. DESIGN: Primary research: randomised controlled trial. SETTING: Primary care. PARTICIPANTS: People without risk factors for influenza or contraindications to vaccination were identified from 20 general practitioner (GP) practices in Liverpool in September 1999 and invited to participate in the study. There were 5875/9727 (60.4%) people aged 65-74 years identified as potentially eligible and, of these, 729 (12%) were randomised. INTERVENTION: Participants were randomised to receive either influenza vaccine or placebo (ratio 3:1), with all individuals receiving pneumococcal vaccine unless administered in the previous 10 years. Of the 729 people randomised, 552 received vaccine and 177 received placebo; 726 individuals were administered pneumococcal vaccine. MAIN OUTCOME MEASURES AND METHODOLOGY OF ECONOMIC EVALUATION: GP attendance with influenza-like illness (ILI) or pneumonia (primary outcome measure); or any respiratory symptoms; hospitalisation with a respiratory illness; death; participant self-reported ILI; quality of life (QoL) measures at 2, 4 and 6 months post-study vaccination; adverse reactions 3 days after vaccination. A cost-effectiveness analysis was undertaken to identify the incremental cost associated with the avoidance of episodes of influenza in the vaccination population and an impact model was used to extrapolate the cost-effectiveness results obtained from the trial to assess their generalisability throughout the NHS. RESULTS: In England and Wales, weekly consultations for influenza and ILI remained at baseline levels (less than 50 per 100,000 population) until week 50/1999 and then increased rapidly, peaking during week 2/2000 with a rate of 231/100,000. This rate fell within the range of 'higher than expected seasonal activity' of 200-400/100,000. Rates then quickly declined, returning to baseline levels by week 5/2000. The predominant circulating strain during this period was influenza A (H3N2). Five (0.9%) people in the vaccine group were diagnosed by their GP with an ILI compared to two (1.1%) in the placebo group [relative risk (RR), 0.8; 95% confidence interval (CI) = 0.16 to 4.1]. No participants were diagnosed with pneumonia by their GP and there were no hospitalisations for respiratory illness in either group. Significantly fewer vaccinated individuals self-reported a single ILI (4.6% vs 8.9%, RR, 0.51; 95% CI for RR, 0.28 to 0.96). There was no significant difference in any of the QoL measurements over time between the two groups. Reported systemic side-effects showed no significant differences between groups. Local side-effects occurred with a significantly increased incidence in the vaccine group (11.3% vs 5.1%, p = 0.02). Each GP consultation avoided by vaccination was estimated from trial data to generate a net NHS cost of 174 pounds. CONCLUSIONS: No difference was seen between groups for the primary outcome measure, although the trial was underpowered to demonstrate a true difference. Vaccination had no significant effect on any of the QoL measures used, although vaccinated individuals were less likely to self-report ILI. The analysis did not suggest that influenza vaccination in healthy people aged 65-74 years would lead to lower NHS costs. Future research should look at ways to maximise vaccine uptake in people at greatest risk from influenza and also the level of vaccine protection afforded to people from different age and socio-economic populations.

Factors affecting influenza vaccination rates in older people admitted to hospital with acute medical problems.

Influenza is a major problem both in the community and hospital and elderly people who are at particular risk should be included in vaccination programmes. In August 1998 the Chief Medical Officer for England extended the current influenza immunization policy to include all those aged 75 years or over. However, prior to this date only those patients with co-existing cardiac or respiratory diseases at increased risk of influenza were vaccinated routinely. In order to determine whether such patients had been immunized, we approached all patients admitted to Care of the Elderly wards during an 8-week period in January and February. The study additionally identified factors that may have influenced patients' participation in this immunization programme. Six hundred and forty-nine patients on Care of the Elderly wards with acute medical illness were questioned with regard to vaccination against influenza during the previous year. Of the 649 patients 279 were suitable for entry into the study. Of these 39% had been vaccinated against influenza. When considering the 171 who were not vaccinated, 25% (44 patients) had actually been offered and declined vaccination, in 46% of these cases due to previous side-effects, or fear of anticipated side-effects. In those unvaccinated three-quarters considered that the influenza vaccine was not efficacious. Unfortunately, patients with co-existing cardiac, respiratory or endocrine diseases were no more likely to have been vaccinated than were those without these diseases. Many older patients admitted with acute medical problems had not been vaccinated against influenza and the reasons for this included not being offered vaccination, a belief that influenza vaccination was not efficacious and concerns about possible side-effects. The role of community doctors and nurses in facilitating the vaccination of such an at-risk group is evident and should be incorporated into resource planning.

Gait disturbance in Alzheimer's disease: a clinical study.

Gait disturbance is common in patients with Alzheimer's disease (AD). The aim of this study was to analyse the clinical gait syndromes of patients with AD using Nutt's classification. Fifty-five patients who satisfied the NINCDS-ADRDA criteria for probable AD and 55 controls were recruited from a geriatric and a psychogeriatric unit. Patients with classical musculoskeletal or neurological syndromes causing gait disturbance were excluded. A standardized neurological examination was carried out in all subjects. Twenty-two (40%) patients and ten (18%) controls had a higher level gait disorder (p < 0.01). The pattern of gait disturbance in AD patients varied according to the stage of the disease. Cautious gait was the commonest gait disorder in AD patients with mild dementia, while frontal gait disorder was the commonest disturbance in patients with severe dementia. The prevalence of frontal release signs (gegenhalten or any primitive reflex) was highest among patients with frontal gait disorder.

Prescription of contraindicated and interacting drugs in elderly patients admitted to hospital.

573 elderly patients admitted to the general medical and geriatric beds of a teaching hospital in January, 1983, were receiving an average of 2.14 drugs on admission, 5.48 during inpatient stay, and 3.47 on discharge. Contraindicated or adversely interacting drugs were identified in 200 (3.2%) of 6160 prescriptions. 136 (23.7%) patients were affected. 7 patients received drugs to which they had had adverse reactions. There were a further 60 contraindicated and 133 adversely interacting drugs. 117 prescriptions were potentially hazardous and another 27 interactions may have led to suboptimal treatment. 131 (65.6%) undesirable prescriptions were deemed avoidable and a further 36 (18%) were probably so. The frequency of errors was higher in admission medication (5.3%) than in hospital prescriptions (2.9%). The importance, origin, and prevention of prescribing errors in drug-induced morbidity in the elderly are discussed.

Smoking cessation.

Smoking cessation has been shown to be cost effective, even in older individuals. It is therefore important that this health promotion is not missed in this vulnerable group.

Side effects of influenza vaccination in healthy older people: a randomised single-blind placebo-controlled trial.

OBJECTIVES: To investigate the frequency of side effects following influenza vaccination in healthy participants aged 65-74 years. MATERIALS AND METHODS: A single-blind randomised placebo-controlled trial was performed in general practices in central Liverpool on 729 healthy individuals (341 females and 388 males) aged 65-74 (median age 68.9) years, of whom 552 received influenza vaccine and 177 received placebo. The main outcome measures were analysed from adverse reactions reported by the subjects on a postal questionnaire 3 days after vaccination. RESULTS: 724 (99.3%) questionnaires were returned. 62 (11.3%) participants who received influenza vaccination complained of local symptoms compared with 9 (5.1%) participants who received placebo (difference 6.2%; 95% CI 1.3 to 10.0%; p = 0.02). 192 (35.1%) individuals who received influenza vaccine complained of one or more systemic side effects compared with 75 (42.4%) who received placebo (difference -7.3%; 95% CI -15.6 to 0.9%; p = 0.10). CONCLUSION: Healthy people belonging to this age group can be reassured that, when compared with placebo, influenza vaccination causes few, if any, systemic side effects and only a low incidence of local side effects.

Acute stroke predisposes to oral gram-negative bacilli -- a cause of aspiration pneumonia?

OBJECTIVES: To assess any change in the oral flora in the mouths of stroke patients during the acute and rehabilitation phases and to determine whether this is related to episodes of aspiration pneumonia and clinical outcome. MATERIALS AND METHODS: This observational study was carried out in hospital wards in a University teaching hospital. The subjects were patients immediately post-stroke and during the rehabilitation period, acute admissions and a group of healthy volunteers. An assessment of dentition and swallow in the presence or absence of oral aerobic gram-negative bacilli (AGNB) was correlated. RESULTS: Of the acute stroke patients 52% had an unsafe swallow. AGNB carriage was documented in 34% of the acute stroke group. Of the 11 patients who died 55% had AGNB, 73% had an unsafe swallow and 36% had a combination of both. CONCLUSION: AGNB is a common finding in acute stroke patients. It is not a consequence of age or acute hospitalisation and is associated with an unsafe swallow and a higher mortality.

The burden of chronic illness in local authority residential homes for the elderly.

A survey of all Part III residential homes in the Central and Southern area of Liverpool Health District examined the diagnoses and medication of 331 residents. A heavy burden of chronic illness was observed with cardio-vascular, psychiatric and orthopaedic problems being the most prevalent. Of the top 10 diagnoses, accounting for over half of all conditions, all disease instances required monitoring of their response to treatment. At least two thirds of these diseases were likely to progress, and the usual treatment of three quarters of the sample was associated with possible side-effects. This heavy burden of chronic illness in Part III residential homes implies a major need for both anticipatory and event-related medical care. These needs are unlikely to be met, given that the subtle, but significant, deterioration in the health of residents has been shown to go undetected.
