Safety assessment for the frail elderly: a comparison of restrained and unrestrained nursing home residents.

OBJECTIVE: To facilitate clinicians' judgement concerning physical restraint decisions by identifying potentially reversible injury risk factors that differentiate representative samples of restrained and unrestrained nursing home residents. DESIGN: Comparison of restrained and unrestrained nursing home residents on a safety assessment for the frail elderly (SAFE) protocol. SETTING: Long-term care facilities in the Greater Los Angeles Area. PARTICIPANTS: One hundred eight physically restrained and 111 unrestrained nursing home residents. INTERVENTION: None. MAIN OUTCOME MEASURES: (1) Internal, Interrater, and test/retest reliability of the overall SAFE protocol and of the four major factors measured by SAFE; (2) The relationship of SAFE scores to expert judgment of resident injury risk; (3) Differences between large samples of restrained and unrestrained residents on specific SAFE score factors. RESULTS: Two walking, one transition, and one judgment factor are reliably measured by the SAFE protocol. SAFE scores were significantly correlated with expert judgment of risk for injury and showed large differences between restrained and unrestrained residents, even after differences in ambulation ability between the two groups were accounted for. CONCLUSION: The SAFE is a reliable protocol that measures behavioral factors related to falls and risk for injury among nursing home residents with a broad range of cognitive impairment. Factors that significantly differentiate restrained and unrestrained groups should be targeted for rehabilitation and remediation in physical restraint reduction efforts. Removing or changing restraints for the large sample (50%) of restrained residents who were not ambulatory will not significantly increase their mobility, since the majority of this group could not independently propel their wheelchairs. Increased mobility for the large group of both restrained and unrestrained residents will likely be realized only if restraint reduction programs are combined with interventions to improve both mobility and the specific behavioral performance factors measured by SAFE.

Failure of prophylactic surgery to avert massive pituitary expansion in pregnancy.

Macroprolactinomas have a well-recognized potential for marked expansion during pregnancy. Measures advocated to minimize this risk include prior treatment with dopamine agonists, radiotherapy and pituitary surgery. We describe a patient who underwent transsphenoidal surgery with the removal of an histologically proven prolactin-secreting adenoma with the intention of rendering subsequent pregnancy safe. The patient remained hyperprolactinaemic and received prolonged therapy with metergoline and bromocriptine which suppressed prolactin to normal and she conceived after induction of ovulation with human menopausal gonadotrophin and human chorionic gonadotrophin. At 3 months gestation she developed headaches, vomiting, reduced visual acuity and bitemporal hemianopia caused by massive pituitary expansion. Reintroduction of bromocriptine rapidly abolished features of tumour expansion and after delivery of a full-term normal female infant, repeat CT scan documented tumour shrinkage.

Megaloblastic anaemia of pregnancy: a clinical and laboratory study with particular reference to the total and labile serum folate levels.

It has been shown that the incidence of megaloblastic anaemia in a group of 463 randomly selected pregnant women receiving iron was 12 times as high as in a control group of 235 pregnant women receiving iron and folic acid. The incidence of all types of anaemia in the women receiving iron alone was more than three times the incidence in those having iron and folic acid. Some women who were not anaemic or who had normoblastic anaemia had serum folate levels in the same range as the women with megaloblastic anaemia, but none of the women with megaloblastic anaemia had high serum folate levels. The labile fraction of the serum folate was no more reliable than the total serum folate as a diagnostic criterion of megaloblastic erythropoiesis in the individual case. The blood group distribution in the women with megaloblastic anaemia was the same as in the general population. Babies born to mothers with megaloblastic anaemia tended to be smaller than the rest, although there was no difference in the placental weights. The significance of these findings is discussed.
