Elderly patients in surgical workloads: a population-based analysis.

Elderly (80+ year old) individuals are the fastest-growing segment of the U.S. population. The objective of this study was to use population-based data to examine trends in the number of elderly undergoing major general, vascular, and cardiothoracic surgical procedures. California inpatient data from 1990-2000 was used to identify patients undergoing six procedures: abdominal aortic aneurysm repair (AAA), coronary artery bypass graft (CABG), carotid endarterectomy (CEA), colon resections, lung resections, and pancreatic resections. Despite comprising only 2.7 per cent of the California population, elderly patients were a significant percentage (6-22%) of the caseloads for the six procedures examined. For all six procedures, the percentage of patients that were elderly increased during the study period. The age-specific incidence rates for elderly individuals increased significantly for three of these procedures (CABG, CEA, lung resection), remained unchanged for two (AAA, pancreas resection), and decreased for one (colon resection). Elderly patients are a large and growing part of surgical caseloads. In the near future, the number of elderly individuals in the California state and the U.S. populations will increase dramatically (41% and 35% between 2000 and 2020). To provide the best quality of care, surgeons should embrace research, training, and educational opportunities regarding the treatment of elderly patients.

On the usefulness of finger blood-pressure measurements for studies on mental workload.

Two experiments were conducted to explore the usefulness of the Penaz method for non-invasive, continuous finger blood pressure measurements during mental stress testing. In the first study, blood pressure was measured with the Penaz method, in the second it was measured intra-arterially. Two different subject groups were used. In both experiments the same mental task, a memory search and counting task, was used. Experimental effects, consisting of rest-task differences in heart rate and blood pressure, its (spectral) variability and the coherence between fluctuations in the two signals (e.g. baroreflex sensitivity) are compared for the two measuring methods. Experimental effects on mean pressure values, spectral variability measures and baroreflex sensitivity are similar for the two types of measurement. Effects on mean pressure are smaller in the finger pressure indices. It is concluded that the Penaz instrument can provide us with a useful method for studying cardiovascular reactivity in mental stress research.

Daily home visiting in one general practice: a longitudinal study of patient-initiated workload.

New requests for home visits performed by one general practitioner were recorded every weekday over 13 years from 1977 to 1989. Overall, a steady reduction in patient-initiated demand for visits was seen. However, longitudinal analysis by age showed that this was statistically significant only in patients aged under 65 years, for whom there was a 71% decrease. There was no significant change in the rates of visits requested for elderly (65-74 years old) and very elderly (75 years and over) patients. In the last year of the study 75% of daily visiting was requested by 18% of the patients, that is by the elderly and very elderly, a sector of the population which is increasing. The findings challenge the prediction that home visits will decline until they eventually disappear. General practitioners in the UK still need to maintain a domiciliary service to their elderly patients.

HIV infection and AIDS in England and Wales: general practitioners' workload and contact with patients.

In mid-1988 a postal survey was conducted of one in five general practitioners in England and Wales, to examine their contact with people with human immunodeficiency virus (HIV) infection, with the acquired immune deficiency syndrome (AIDS) or with worries about HIV infection or AIDS. The response rate was 63.9%. Of the 3339 respondents 22.7% knew of an asymptomatic HIV positive patient within their practice, 5.4% knew of a symptomatic HIV positive patient and 6.4% knew of a patient with AIDS. The estimated annual rate for HIV-related consultations in general practice (including consultations with the 'worried well') was 6.5 per 1000 population. HIV-related consultations occurred more frequently in the four Thames health regions than elsewhere. A sample of 715 practitioners who reported consultations with HIV infected people or those with worries about infection in the previous month, were invited to keep a diary of HIV-related consultations for one week. The response rate to the diary was 64%. Nineteen per cent of the 273 consultations recorded in the diaries were initiated by homosexual men, 16.5% by injecting drug users, 10.3% by the sexual partners of people at risk of infection; 42.9% of consultations were not associated with recognized risk factors. The results indicate that general practitioners have substantial contact with patients with HIV infection, with AIDS and with worries about HIV infection or AIDS. This contact is likely to increase, alongside the anticipated spread of HIV infection, with consequent implications for general practice resources.
