Visitors' perceptions of continuing care.

One hundred and sixty-one replies (72% response rate) to a questionnaire sent to regular visitors of elderly continuing care patients showed that 73% of the visitors were first degree relatives. Sixty three per cent visited more than once per week, and were more likely to do so when the distance travelled was less than five miles (p less than 0.01) and the cost under pounds 2.00 (p less than 0.01). The physical surroundings and nursing care were rated as adequate or better by 80% and 92% respectively. Numbers of nurses were rated as inadequate by 44% and numbers of physiotherapists as inadequate by 46%. Increasing the numbers of nurses was suggested as the measure that would most improve the patients' quality of life. To facilitate visiting, continuing care units should be sited close to the community they serve.

Continuing hospital care in Scotland: a survey of consultant geriatricians.

We report a survey of Consultant Geriatricians in Scotland with regard to the provision of continuing geriatric care. There are wide variations in the numbers of patients that individual consultants are responsible for, the type and geographical site on which a service is provided, and also in views on the adequacy of staffing levels. Quality of physical surroundings and nursing care are generally thought to be more than adequate. Consultants believed their main contribution was providing expert medical advice, and felt their patients' quality of life could most be improved by increased diversional therapy. There are wide geographical differences in the number of private nursing and residential homes in Scotland but they have had some influence on the criteria for placement of patients in continuing hospital care.

Acute appendicitis in the elderly: a 5-year retrospective study.

Acute appendicitis in elderly patients has not been studied extensively in the United Kingdom. Studies were performed prior to the regular use of broad spectrum antibiotics and tended to include younger patients. We studied retrospectively all elderly patients (n = 30, mean age = 72 years) who presented in the years 1980-85 and a younger group (n = 30, mean age = 23 years) who had a confirmed pathological diagnosis of appendicitis. We found a significant reduction in accurate pre-operative diagnoses, a longer duration of hospital stay and increased complication and mortality rates in the elderly group. Our study suggests that diagnostic accuracy, mortality and morbidity have not improved in comparison to earlier overseas studies.

Echocardiographic diagnoses in elderly patients with systolic murmurs and cardiac disease.

M-mode and 'real-time' echocardiography was employed to study 100 elderly with systolic murmurs and cardiac disease. Technically adequate recordings were obtained in 89 patients. Independent assessment of the echocardiographs showed good reproducibility. Aortic sclerosis was the most prevalent lesion, but did not by itself impair left ventricular function. The echocardiographic diagnosis of mitral regurgitation was significantly related to heart failure and atrial fibrillation. A link between murmur and cardiac disease was postulated in 40% of cases.

Systolic murmurs in pregnancy: value of echocardiographic assessment.

A systolic murmur discovered in antenatal care is the most common reason for cardiological assessment during pregnancy. We have assessed the value of clinical and echocardiographic assessment in 50 consecutive patients who were referred to our cardiac clinic following the discovery of a cardiac murmur at an antenatal clinic. Most of the murmurs occurred at 10-12 weeks gestation; 46 subjects had cardiac murmurs confirmed at the cardiac clinic, of whom 16 gave a history suggestive of a previous cardiovascular disorder. Of the 16 patients, 13 had been found to have a murmur earlier in life which was thought to be of no clinical significance. Complications during pregnancy were infrequent. The most frequent murmur discovered was a soft midsystolic murmur heard with greatest intensity at the left sternal edge. The results of electrocardiography and echocardiography were not helpful in assisting with the diagnosis or substantially altering antenatal management in these patients. We do not feel that echocardiography has an important role in the assessment of systolic murmurs in pregnancy in the absence of other clinical or ECG abnormalities.

Are insulin dependent diabetics in the West of Scotland prone to nutritional deficiencies?

In a cross-sectional survey, the weight, vitamin and mineral status of 57 insulin dependent diabetics attending a clinic in Glasgow were studied. There were no significant differences in any of the measured parameters between poorly controlled and better controlled diabetics (as assessed by HbA1 status). No gross evidence of nutritional deficiency was found although serum magnesium levels tended to be low. This may be clinically relevant as hypomagnesaemia is associated with cardiac arrhythmias and ischaemic heart disease.
