Cost-effectiveness of an interdisciplinary intervention in geriatric inpatients to prevent malnutrition.

BACKGROUND: In order to reduce protein-energy malnutrition in older people during hospitalisation an early interdisciplinary intervention is needed. We developed a protocol which includes screening for malnutrition, dysphagia and dehydration on admission, followed by immediate interventions. OBJECTIVE: To assess effectiveness of the protocol on nutritional status, hospital-acquired infections and pressure sores, and to evaluate the protocol s economical feasibility. DESIGN: Prospective, controlled study. SETTING: The inpatient geriatric service of a university hospital (UMC Nijmegen) and a geriatric ward of a non-academic teaching hospital (Rijnstate Hospital, Arnhem). SUBJECTS: 298 older patients (>60 years). METHODS: One of the geriatric wards applied the protocol (N=140) while the other provided standard care (N=158). All non-terminally ill patients admitted for more than two days were included. Body mass was measured on admittance and discharge and hospital-acquired infections and pressure sores were scored and costs related to nutrition, infections and length of hospital stay were assessed. RESULTS: There was a 0.8 kg loss (SEM 0.3 kg) in average weight in the standard care group and a 0.9 kg gain (SEM 0.2 kg) in the intervention group (p<0.001). The number of hospital acquired infections was significantly lower in the intervention group (33/140 versus 58/158, p=0.01) but no significant difference in number of patients with pressure sores (23/140 versus 33/158) was found. Costs were not significantly different: 7516 versus 7908 Euro/patient for intervention versus controls, respectively. CONCLUSION: An early interdisciplinary intervention approach can be effective in reducing protein-energy malnutrition and related hospital-acquired infections and appears to be economically feasible.

Prevention of relapses in systemic lupus erythematosus.

Many relapses of systemic lupus erythematosus (SLE) are preceded by a rise in antibodies against double-stranded DNA (anti-dsDNA). We investigated whether these relapses can be prevented by giving prednisone when a rise in anti-dsDNA occurs. 156 patients with SLE were studied. Anti-dsDNA was measured by Farr assay monthly. When a rise in anti-dsDNA was found, patients were randomly assigned either conventional treatment or 30 mg prednisone added to the current daily dose and tapering off to baseline over 18 weeks. A rise in anti-dsDNA was detected in 46 patients (24 assigned conventional treatment and 22 prednisolone). The relapse rate was higher in the conventional group than in the prednisolone group (20 vs 2, p < 0.001). Although rises in anti-dsDNA in the prednisone group were treated with additional prednisone, the cumulative oral doses of prednisone in the two groups did not differ significantly (p = 0.025). 7 major relapses requiring additional cytotoxic immunosuppressive treatment occurred in the conventional group versus 2 in the prednisone group. Treatment with prednisone as soon as a significant rise in anti-dsDNA occurs prevents relapse in most cases, without increasing the cumulative dose of prednisdone given.

Ischemic damage to the spinal cord following surgery of the abdominal aorta.

Ischemic damage to the spinal cord after reconstructive procedures of the abdominal aorta is a rare complication. The literature up to and including 1980 records 46 of these cases. In this paper we present four additional cases and discuss the etiological factors and the practical measures available to minimize the risk of this unpredictable complication.

Ischiadic nerve entrapment by an extra- and intrapelvic lipoma: a rare cause of sciatica.

A 60-year-old woman had persistent left-sided ischialgia. After several years, a left-sided subgluteal mass extended to the pelvis. Computed tomography (CT) disclosed a large subgluteal and intrapelvic lipoma. Symptoms were relieved by excision of the tumor.
