We assessed the outcome of dysphagia rehabilitation in all the 139 patients with post-stroke dysphagia admitted to our Neurorehabilitation Unit during 2 years (2017 and 2018), divided into two groups: old (aged 65-84 years) and oldest-old (aged 85 or above). We studied which factors predicted dysphagia improvement in the two groups. The potential association of improvement with type of discharge was also evaluated. On admission, 'old' patients had more frequently aphasia (P = 0.02) and less frequently dysarthria (P = 0.03); 'oldest old' had more severe pressure ulcers (P = 0.008), higher levels of c reacting protein (P = 0.01) and more heart problems (P = 0.004). None of these factors was associated with the outcome of dysphagia. We found no difference between the two groups in the severity of dysphagia, as measured with Dysphagia Outcome and Severity Scale on admission and discharge, but due to minor differences, the degree of improvement was higher in the 'old' group (P = 0.02). The number of patients discharged with improved swallowing was also comparable. Cognitive impairment had a negative predicting role in the 'old' group (odds ratio 0.270, 95% confidence interval 0.101-0.725, P = 0.007). Norton Scale score predicted dysphagia improvement in the 'oldest old' group (odds ratio 1.611, 95% confidence interval 1.102-2.355, P = 0.007). Dysphagia improvement was associated with discharge home in general (P = 0.011) and in the 'old' group (P = 0.04). Our data, though preliminary, could give a contribution to implement patient-specific rehabilitation strategies; these could increase swallowing improvement in post-stroke dysphagia.

Background: Comorbidities are a growing problem in older patients in many clinical settings, but electronic records may give an unsatisfactory picture of this complexity. Analysis of drug prescriptions can add further diagnostic information to that gathered from billing diagnostic codes, but the risk exhists that potentially inappropriate prescriptions may lead to over-estimating comorbidities. Methods: We analysed the administrative records and drug prescriptions of the 304 patients discharged during 2016 from a neurological rehabilitation unit. International Classification of Diseases – 9th revision diagnostic codes were matched with prescriptions at discharge, coded according to the Anatomical Therapeutic Chemical classification. The codes of the prescriptions not explained by the diagnostic codes were recorded, grouped, corrected for potential inappropriate prescribing, and analysed. Results: Of the 304 patients, 295 had at least one prescribed drug not inferable from their diagnostic codes. The mean number of these prescriptions was 3.5 ± 1.9 per patient, and that of prescriptions remaining after correction for potentially inappropriate prescribing was 2.0 ± 1.5. The more frequent groups of potentially inappropriate medications were anti-acids, psychotropic drugs, laxatives, potassium supplements, cardiovascular drugs and lipid modifying agents. Administrative databases underestimate the complexity of older patients in neurological rehabilitation wards. More reliable data can be obtained by adding the analysis of drug prescriptions, but correction for potentially inappropriate prescription seems necessary to avoid an over-estimation of comorbidities.

BACKGROUND Dysphagia prevalence increases with age and a significant contribution is given by stroke survivors; its treatment is mainly based on rehabilitation, but outcome cannot be easily predicted. OBJECTIVE The aim of this study is to detect possible predictors of the outcome of dysphagia in patients beginning rehabilitation after a major Central Nervous System injury. METHODS Dysphagia severity was measured in 95 consecutive patients (71 with ischemic or hemorrhagic stroke) upon admission to our neurorehabilitation unit and at discharge, during the year 2017. The initial evaluation included also demographic data, functional and geriatric multidimensional assessment, laboratory test results and comorbidities. Their possible predictive value on the degree of recovery of the swallowing process at discharge has been analyzed. RESULTS Poor functional conditions and the presence of cognitive impairment on admission appear to be associated with a worse outcome of dysphagia at discharge. A significant correlation exists between scores at functional scales at the beginning of rehabilitation and dysphagia score at discharge. Patients with cognitive impairment at the beginning (n = 60) showed a significantly lower degree of recovery of dysphagia at discharge. CONCLUSION Other factors, beside the degree of dysphagia itself, are important to predict its outcome. Their knowledge not only allows an initial prognostic assessment; it can also be useful to decide which aspects should receive greater attention when treating patients with dysphagia.

From 1990 to 1993, 115 diabetic patients were consecutively hospitalized in our diabetologic unit for foot ulcer and 27 (23.5%) major amputations were carried out. The major amputation rate of this series of cases was compared with that occurring in diabetic subjects taken into our hospital for foot ulcer in two previous periods: 1979-1981 (17 major amputations in 42 inpatients or 40.5%) and 1986-1989 (26 major amputations in 78 inpatients or 33.3%). The comparison shows a progressive reduction in major amputation rate [Odds ratio 0.66, 95% confidence interval (CI) 0.46-0.96]. Univariate and multivariate analysis, carried out in the population of the 1990-1993 period, in order to detect the independent factors associated with major amputation show the following prognostic determinants of major amputation: Wagner grade (odds ratio 7.69, CI 1.58-37.53), prior stroke (odds ratio 35.05, CI 3.14-390.53), prior major amputation (odds ratio 3.49, CI 1.26-9.38), transcutaneous oxygen level (odds ratio 1.06, CI 1.01-1.12), and ankle-brachial blood pressure index (odds ratio 4.35, CI 1.58-12.05), while an independent protective role was attributed to hyperbaric oxygen treatment (odds ratio 0.15, CI 0.03-0.64). In accordance with other studies, we, therefore, conclude that a comprehensive protocol as well as a multidisciplinary approach in a dedicated center can assure a decrease in major amputation rate. The parameters of limb perfusion were the modifiable prognostic determinants most strongly predictive for amputation.
