Variability of blood pressure response to orthostatism and reproducibility of the diagnosis of orthostatic hypotension in elderly subjects.

BACKGROUND: Orthostatic hypotension (OH) is a major problem in the elderly population. Its diagnosis is based on measurement of the blood pressure (BP) response to orthostatism (BPRO). This study investigates the within-day and day-to-day variability of the BPRO and the reproducibility of the diagnosis of OH in this population. METHODS: BP was measured in the supine position and after 1 and 2 minutes of orthostatism in 53 consecutive elderly patients (43 women and 10 men aged 83.7 +/- 9.5 years) of an intermediate care geriatric ward. BPRO was assessed 4 times on the same day (8-9 AM, 10-11 AM, 1-2 PM, and 5-6 PM) and twice more on another day of the same week (8-9 AM and 1-2 PM). RESULTS: There were significant within-day differences between the four orthostatic changes in systolic BP (OCs, supine minus standing systolic BP) after 1 minute or 2 minutes (p < .05). Day-to-day differences between the OCs measured at the same times were not significant. OH defined as an OCs of 20 mm Hg or more at 1 or 2 minutes of orthostatism, was found in ten cases (19%) in the initial set of measurements on the first day. A cumulative diagnosis of OH after the six BPRO tests was found in 23 cases (43%). The reproducibility of the diagnosis of OH was mild or poor (all kappa values were below 0.47). CONCLUSIONS: BPRO exhibits significant within-day variability in elderly patients. Within-day and day-to-day reproducibility of the diagnosis of OH, based on conventional criteria, were found to be poor.

[Nutritional support in elderly malnourished patients]. / L'assistance nutritionnelle chez les malades âgés dénutris.

ASSESSMENT OF NUTRITIONAL STATUS: Protein-calorie malnutrition is frequent and often severe in fragile hospitalized or institutionalized elderly subjects. Underdiagnosis and undertreatment is commonplace. Since under- or malnutrition is more difficult to correct in the elderly than in the young subject, a careful assessment of the nutritional status must be made in order to recognize any nutritional disorder early and initiate proper treatment early. NUTRITIONAL ASSISTANCE: High-protein oral supplementation and complementary enteral nutrition can improve the clinical status of certain under- or malnourished elderly subjects. It is particularly important to initiate nutritional assistance early and provide effective treatment for any recognized surgical or medical cause of malnutrition. Patient cooperation is crucial. EXPECTED RESULTS: Associated early with rehabilitation therapy, nutritional assistance can be expected to improve the functional independence of the elderly patient. Treatment efficacy and patient tolerance must be evaluated regularly to adapt nutritional assistance to the patient's particular clinical situation. Intensive enteral nutrition is not appropriate for elderly patients with severe malnutrition whose quality of life is compromised by motor, psycho-cognitive, or sensorial handicaps.

[Quality of the information collected during admission to a hospital geriatric service: importance of a structured medical record]. / Qualité du recueil d'information à l'admission en service hospitalier de gériatrie: intérêt d'un dossier médical structuré.

OBJECTIVES: The medical record (MR) is a key document for hospitalized patients. Several audits have however demonstrated that much important information is often missing in hospital MR. We conducted this survey with the aim of improving the quality of MR in a geriatric unit. PATIENTS AND METHODS: A structured MR was elaborated and implemented in order to guide and record the assessment of patients admitted in our geriatric ward. MR of 54 consecutive patients admitted after implementation of the structured MR were studied and compared to those of 108 consecutive patients admitted on the preceeding year (classical MR). Quality of data collected at admission was assessed using a 33-item guide, proposed by 3 experts in geriatric medicine unaware of the structured MR studies. For each item, a binary score (present/absent) and a precision score were used. A validation study was conducted using the same methods in another geriatric ward which has not participated to development of the structured charts MR studied. RESULTS: For most items studied, information was present in a significantly higher proportion in structured MR than in classical MR. Likewise, the precision score was significantly higher in structured MR. The validation survey found analogous results. CONCLUSION: Use of a structured MR significantly improves the quality of data collection at admission in geriatric units. This improvement appears to be related more to the use of the structured MR than the effect of developing a new tool.
