Therapeutic educational workshops for caregivers of patients with severe acquired brain injury

Abstract

Severe acquired brain injury (sABI) leads to a wide range of functional limitations in cognitive, moto and behavioural abilities. These changes impact the patient's family in terms of the feeling of emotional and physical health, social life and financial condition. Caregivers are often intensely involved in the patient's management exposing them to negative effects of caregiving including stress, mood disorders and decreased quality of life. Implementing forms of active involvement of caregivers in the rehabilitative program could be useful. Thus, in the present study, therapeutic educational workshops (TEWs) for caregivers during the post-acute intensive hospitalization were organized during the post-acute intensive hospitalization of patients with sABI. The caregivers were asked to participate in the workshops to actively involve them in the patient's care and neurorehabilitation program. Each workshop session provided indications regarding the management of the patient with aphasia, neglect, behavioural and swallowing disorders. A questionnaire of 22 items has been designed in order to represent possible indicators of usefulness and effectiveness of the TEWs. The primary aim of this study was to develop a reliable and valid questionnaire able to assess the caregivers' satisfaction with the modalities of carrying out the TEW as a novel activity during the post-acute hospitalization of patients with sABI. The second aim was to assess the caregivers' satisfaction with the utility of the TEW as a tool to enhance their skills in the management of patients' disabilities. 100 caregivers of patients with sABI who attended at least one TEW session and completed the questionnaire were included in the analysis. In conclusion the administered questionnaire has proven to be a valid and reliable tool to evaluate sABI caregivers' satisfaction with TEW. Moreover, caregivers were satisfied with the organization of the TEW and with their usefulness in the management of the patients with sABI.

Risk factors for colonization with extended-spectrum beta-lactamase-producing enterobacteriaceae on admission to rehabilitation centres

Patients newly admitted to rehabilitation centres are at high risk of colonization with multidrug-resistant bacteria because many of them have experienced prolonged stays in other healthcare settings and have had high exposure to antibiotics. We conducted a prospective study to determine the prevalence of and risk factors for colonization with extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) in this population. Subjects were screened by rectal swab for ESBL-PE within 2 days of admission. Swabs were plated on chromagar ESBL plates and the presence of ESBL was verified by a central laboratory. A multilevel mixed effects model was used to identify risk factors for ESBL-PE colonization. Of 2873 patients screened, 748 (26.0%) were positive for ESBL-PE. The variables identified as independently associated with ESBL-PE colonization were: recent stay in an acute-care hospital for over 2 weeks (OR=1.34; 95% CI, 1.12, 1.6), history of colonization with ESBL-PE (OR=2.97; 95% CI, 1.99, 4.43), unconsciousness on admission (OR=2.59; 95% CI, 1.55, 4.34), surgery or invasive procedure in the past year (OR=1.49; 95% CI, 1.2, 1.86) and antibiotic treatment in the past month (OR=1.80; 95% CI, 1.45, 2.22). The predictive accuracy of the model was low (area under the ROC curve 0.656). These results indicate that ESBL-PE colonization is common upon admission to rehabilitation centres. Some risk factors for ESBL-PE colonization are similar to those described previously; however, newly identified factors may be specific to rehabilitation populations. The high prevalence and low ability to stratify by risk factors may guide infection control and empirical treatment strategies in rehabilitation settings.

A multinational study of colonization with extended spectrum β-lactamase-producing Enterobacteriaceae in healthcare personnel and family members of carrier patients hospitalized in rehabilitation centres

The study aims were: (i) to define the prevalence of and risk factors for colonization by extended spectrum β-lactamase (ESBL) -producing Enterobacteriaceae (EPE) among healthcare workers (HCWs) and family members (FMs) of EPE-colonized patients in rehabilitation units and (ii) to compare EPE isolates from these three groups. The study included 286 FMs of 194 EPE-carrying patients identified in five rehabilitation units located in Israel, Italy, France and Spain. The EPE were detected in rectal swabs from 26 (9%) of 286 FMs screened. In multivariate analyses, older age of FM, greater mean number of hours spent with the patient, being a daughter or a female spouse of a patient, and chronic lung disease of the patient were significantly associated with carriage in the FM. Escherichia coli was the most common organism (76%), followed by Klebsiella pneumoniae (19%). Isolates were typed by pulsed field gel electrophoresis and multilocus sequence typing, and ESBLs were identified by PCR sequencing. A comparison of paired species isolates from FMs and their respective patient showed that 17 of 23 strains were indistinguishable. EPE were detected in 35 (3.5%, E. coli = 34) of the 1001 HCWs screened. Feeding patients was associated with EPE carriage by HCWs. Only 7 of 23 E. coli subclones cultured from HCWs were also represented among 376 patient-derived ESBL-producing E. coli isolates from the same rehabilitation units. In Spain, a higher proportion of HCWs and FMs were ESBL carriers than elsewhere (p <0.05). In conclusion, the molecular and epidemiological data suggest that FMs are at higher risk of EPE acquisition from their relative patients than HCWs.

A binational cohort study of intestinal colonization with extended-spectrum β-lactamase-producing Proteus mirabilis in patients admitted to rehabilitation centres

The aims of our study were to analyse the risk factors for colonization by Extended-spectrum β-lactamases (ESBL)-producing Proteus mirabilis (ESBL-PM) in rehabilitation patients and to characterize the molecular features of these strains. The study was conducted in two rehabilitation centres located in Rome, Italy (Fondazione Santa Lucia IRCCS (FSL)), and Tel-Aviv, Israel (Tel-Aviv Sourasky Medical Center (TASMC)). Carriage of ESBL-PM was surveyed by rectal swabs. Strain typing was performed by pulsed-field gel electrophoresis (PFGE). Identification of ESBL genes was done by PCR and sequencing. Patients admitted to the same institutions without ESBL carriage were included as controls. The study group included 70 and 41 patients from FSL and TASMC, respectively. In FSL, the multivariate analysis identified severe acute brain injury (OR = 15, 95% CI = 3.2-69.5, p 0.001), decubitus ulcer (OR = 3.5, 95% CI = 1.2-9.8, p 0.018) and recent treatment with quinolones (OR = 5.7, 95% CI = 1.07-30.1, p 0.042) as independent risk factors. ESBL-PM carriers stayed longer in the hospital on average and were less likely to be discharged home. No significant risk factor was identified in TASMC. There were no similarities in PFGE types or ESBL genes between the ESBL-PM isolates from the two institutions. In both hospitals, a variety of PFGE types existed but a single ESBL type predominated, namely TEM-92 in FSL (n = 64/70; 91%) and CTX-M-2 in TASMC (n = 37/41; 90%). A new TEM ESBL variant, TEM-177 was identified in FSL. The clonal diversity and the predominance of a single ESBL type suggested that horizontal gene transfer played an important role in dissemination of resistance. The development of a population analysis tool that would allow tracing deeper genetic relationships is required.

Validity of a questionnaire for the semi-quantitative evaluation of dietary intake of hospitalised patients compared to weighed records

BACKGROUND

Malnutrition in hospitalised patients is often underestimated. The present study aimed to evaluate the validity of a questionnaire for the semi-quantitative evaluation of food intake compared to weighed records in patients who were hospitalised for the rehabilitation of neurological disorders.

METHODS

Food intake at breakfast, lunch and dinner was evaluated in 319 in-patients, by weighing the meals and the residuals, and using a semi-quantitative questionnaire, during five consecutive days. The questionnaire represented, for each offered food, the pictures of the nonconsumed quantities. The consumption of each food was determined by weighing foods that were served and the residuals after the meal. As a measure of validity of the questionnaire, the agreement over chance (kappa statistic) between the questionnaire and the weight was calculated. Considering the weight as the gold standard, the sensitivity and specificity of the questionnaire in detecting patients who consumed <50% or 75% of the meals was calculated.

RESULTS

The agreement between the two measures was satisfactory (κ ≥ 0.70) or almost satisfactory (0.60 < κ < 0.70) for most of the foods, with the exception of fruit and the first course at dinner. The sensitivity and specificity of the questionnaire in detecting consumers of <50% or 75% of the offered foods were always >80%, except for bread and first course, as well as fruit at dinner.

CONCLUSIONS

The present study shows that this semi-quantitative questionnaire on food consumption reproduces with sufficient precision the measures obtained by weighing. The questionnaire appears also to be a valid and suitable instrument for the identification of patients with poor food intake in a neurorehabilitation hospital.

Post-stroke rehabilitation: an economic or medical priority? Current issues and prospects in light of new legislative regulations

The aim of this study was to evaluate: 1) whether the reduction in duration of in-patient rehabilitation imposed by the Italian Ministry of Health's circular of 29/6/95 has been accompanied by a decline in the results achieved; and 2) whether the system of basing payments on diagnosis related group (DRG) criteria is capable of correctly evaluating differences in post-stroke clinical pictures. The study involved 461 of 497 patients consecutively admitted between 1991 and 1996 for rehabilitation after a first stroke. The average duration of hospitalisation for the period 1995-1996 was significantly shorter (p<0.001) than that of the previous years; at the same time, there was a significant increase (p<0.05) in the number of poor responders in both neurological and functional (mobility) terms. Furthermore, the early discharge after 60 days of the 1995-1996 patients compromised the stabilisation of recovery and led to a subsequent functional decline. It is therefore hoped that the current regulations will be revised and that payments based on a functional related group (FRG) criterion will be introduced.

Characterization of endemic Shigella flexneri strains in Somalia: antimicrobial resistance, plasmid profiles, and serotype correlation

One hundred twelve Shigella flexneri strain isolated from children with diarrheal disease in Somalia in 1983, 1984, 1988, and 1989 were analyzed for serotype, plasmid profile, and genetic location of antimicrobial resistance determinants. The prevalent serotypes were 4 (46% of the isolates), 1b (16%), 2a (16%), 3a (12%), and 6 (8%). Each serotype was associated with a characteristic predominant plasmid profile, whereas no specific correlation between antimicrobial resistance patterns and single serotypes was found. All but three of the strains were resistant at least to ampicillin, chloramphenicol, spectinomycin, and tetracycline. Of these resistant strains, 41 were resistant to sulfonamide and streptomycin and 14 were resistant to trimethoprim or trimethoprim and kanamycin. The genes for resistance to ampicillin, chloramphenicol, spectinomycin, and tetracycline formed a linkage group located on the chromosome of the strains of all serotypes. The genes for resistance to sulfonamide and streptomycin were located on a 6.3-kb plasmid in strains of serotypes 1b, 2a, and 4. Conjugative trimethoprim or trimethoprim and kanamycin resistance plasmids with lengths of 80 to 110 kb were present in strains of serotypes 1b, 2a, 3a, and 4. The systematic presence of a chromosomal component in this uncommon genetic plasmid-chromosome configuration may play a role in the emergence of increased genetic stability of resistance patterns in S. flexneri.

[Alizapride in upper digestive endoscopy. A double-blind study vs metoclopramide and placebo]

In order to assess the antiemetic properties of alizapride in the specific context of premedication for endoscopy, a double blind test was conducted on 100 patients against both metoclopramide and a placebo. Efficacy was assessed on the basis of the following parameters: technical judgement of the endoscopist; assessment of evident signs of "discomfort" by an outside observer; comparative judgement (better, worse, same) of the patient's condition after the two endoscopies performed. In the case of the first two parameters, alizapride proved significantly more effective than the control substances. The patients themselves only expressed a significant preference for alizapride vis-à-vis the placebo. It is concluded that given its efficacy and the absence of side effects, alizapride is of value in premedication for endoscopy.
