[Preventive activities for the elderly--what happens after screening?].

Preventive geriatric health care has become a regular part of geriatric health service in some of Norway's municipalities. There are many reports concerning the findings from screenings, but there is little material about the target group's experience with the subsequent intervention. This article describes the results from interviews with the elderly in three municipalities, concerning the perceived value of participating in geriatric screening. A random sample comprising 60 persons with a registered need of intervention was interviewed. Of the registered needs, intervention was implemented in 69 percent of the cases. In 65 percent of the cases the elderly person was satisfied with the intervention, five percent were dissatisfied and for 30 percent, the registration of a need for intervention had no practical significance. In 26 percent of the cases of registered need, the elderly person planned to seek assistance from the health/assistance services on his/her own. The most important reasons why intervention was not implemented were: the lack of a service to intervene in cases of loneliness and/or social isolation, and the lack of motivation on the part of the elderly to seek dental treatment.

Health-care screening among the elderly--a comparison between participants and non-participants.

Geriatric screening at health clinics has become a regular feature of the health-care services offered in some Norwegian municipalities. Normally there is good participation in such screening programmes, but there are always some non-attenders. There is little published material showing the intervention needs among non-respondents. In a municipality in the middle parts of Norway, screening was offered to the municipality's elderly inhabitants at the local health clinic. Those who did not attend were offered a domiciliary visit. The findings indicate that there is a category of people among those who do not attend for screening at the health clinic who have less need of a medical examination and socioeconomic support than those who do attend the screening. There is also a category in need of community nursing, technical aids and health care because of senile dementia, depression and unsought social isolation.

An economic appraisal of two strategies in geriatric screening.

Screening for preventive geriatric health-care has become common in many Norwegian municipalities. Different methods are used to screen for unreported need of intervention. There is little information available about which is the most costeffective method. This article describes a comparison of two screening models. The first screening was conducted by means of a personal interview held at a health clinic and the second by a postal questionnaire. The results show that a postal questionnaire study was more cost-effective than the health-clinic consultation. It demanded no more resources than the health-clinic model, but had a wider effect because it covered a broader spectrum with regard to response, proportion of the total population and the proportion of respondents for whom an intervention was implemented.

Effect of hemorrhage and resuscitation on subcutaneous, conjunctival, and transcutaneous oxygen tension in relation to hemodynamic variables.

Subcutaneous (PscO2), conjunctival (PcjO2), and transcutaneous (PtcO2) oxygen tension values were measured in anesthetized dogs subjected sequentially to hemorrhage and reinfusion of the shed blood. Intravascular pressure, hemodynamic variables, and oxygen transport variables were measured simultaneously. During hemorrhage, PscO2 was the first of the PO2 measurements, and among the first set of hemodynamic variables that differed significantly from control values. During continuous bleeding, PscO2 and PcjO2 fell rapidly, the decline of PscO2 and PcjO2 was similar and significantly higher than that found for PtcO2. After reinfusion of shed blood, PscO2 was the last of PO2 measurements, and among the last set of hemodynamic variables, to return to control values. While PaO2 remained constant, PvO2 decreased significantly during hemorrhage and normalized during resuscitation. Unheated instruments for measuring PscO2 and PcjO2 are reliable indicators of peripheral perfusion during hemorrhage and resuscitation. Subcutaneous oxygen monitoring, in particular, seems capable of assessing early blood loss and adequacy of resuscitation after acute hemorrhage, and may be clinically useful.

Intraaortic balloon pumping in the treatment of low cardiac output following open heart surgery--immediate results and long-term prognosis.

From 1979 through 1986, 90 patients required intraaortic balloon pumping (IABP) due to low cardiac output complicating open heart surgery. Preoperatively, functional class III or IV was present in 92%; in patients with coronary artery disease (n = 54), three-vessel or left main disease was found in 72%; patients with valvular disease (n = 37) generally had multiple surgical procedures or valve re-replacement performed. Intra-IABP mortality was 49% (n = 44) and 30-day mortality 61% (n = 55). The latter figure decreased from 75% in 1979-81 to 53% in 1985-86. Cumulative 5-year survival was 22%. Logistic regression analysis identified as independent predictors of 30 day mortality the necessity for adjuvant treatment with the more powerful "pressure drugs" isoprenaline/noradrenaline, number of DC-defibrillations, functional classes III-IV, and chronic left ventricular failure. Different combinations of these risk factors identified different patient groups with 30-day mortalities ranging from 100% to 0%. The risk factors reflected both acute cardiac failure probably due to severe ischemia and chronic failure due to advanced primary disease. Taking the high-risk composition of the material into account, a 5-year survival of 22% cannot be regarded as discouraging. Continued employment of IABP treatment in open heart surgery, using an aggressive approach coupled with individualized inotropic support, seems justified.
