Improvement of the composting time for household waste during an initial low pH phase by mesophilic temperature control.

Earlier studies indicated that the activity in the initial phase of composting may be reduced when the temperature rises too fast under low pH conditions. A compost reactor experiment on household waste was designed to test whether the degradation time could be reduced by actively preventing the temperature from rising until the pH had reached a certain value. This experiment was performed by monitoring pH in the condensate from the cooled compost gas. The results from 3 + 3 runs with and without temperature control confirmed our hypothesis and a considerable reduction in composting time was achieved. One possible explanation for the results is that the microbes active in the low pH phase are hampered by high temperature. The abrupt rise in pH when the fatty acids are consumed seems to be a good marker of the point when temperature control can be discontinued.

Caring for severely ill cancer patients. A comparison of working conditions in hospital-based home care and in hospital.

The goal of the study was to compare working conditions in a hospital with the conditions in a specialized hospital-based home care (HBHC) unit, which aims to replace hospital care for patients in need of institutional car. Staff (doctors included) in a HBHC unit (n = 35) and on three hospital wards (n = 113) participated in the study. All staff members worked regularly with severely ill cancer patients. Question about stress, job satisfaction and working conditions were asked in a self-administered questionnaire. Both groups showed a limited degree of continuous stress and a high degree of job satisfaction. Thus, the overall perception was than the working conditions were good. When significant differences were found, the responses of the HBHC staff were more positive. This included items such as more freedom to make their own decisions (P < 0.001), better co-operation between day and night shifts (P < 0.001), a more reasonable work load (P = 0.0001), fewer problems in communication with patients (P < 0.001), and fewer problems with tension (P < 0.05) and with sleeping (P < 0.05). The findings may be due to several factors: the HBHC staff were older, more often married, had more children, had worked longer in health care and were thus more experienced. Complementary explanations may be continuous education within the HBHC and an organization stimulating the staff's own initiative, but also capable of supporting when necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

The family in hospital-based home care with special reference to terminally ill cancer patients.

Eighty-seven next of kin, 80 spouses and seven adult children, were the primary caregivers of terminally ill patients (87% cancer patients) cared for at the hospital-based home care (HBHC) unit of Motala Hospital during 1989-1990. All of the patients died in their homes. Next of kin were asked to complete self-questionnaires and to give written comments on their experiences and their perception of how the patient had felt about 13 aspects of home care provided by the HBHC staff. The response rate was 94%. In nine out of 13 areas, such as adequate information at the time of referral about the HBHC, security, support, immediate extra help when needed, high quality of nursing, and care and pain control, 86%-97% of next of kin were very satisfied (7-9 on a 9-point scale); whereas information provided about the disease, economic support, and support given after death were very satisfactory according to 72%, 58%, and 80% of relatives, respectively. Gender and time from diagnosis to death did not seem to affect responses. Next of kin of cancer patients were generally more satisfied than next of kin of other terminally ill patients. A total time of care of more than 60 days (median time) was associated with significantly more positive responses. Older spouses were significantly more satisfied with the HBHC than younger ones; despite this, 99% of all next of kin would choose HBHC again in a similar situation.(ABSTRACT TRUNCATED AT 250 WORDS)

The organization of hospital-based home care for terminally ill cancer patients: the Motala model.

In 1977, the first palliative home care programme in Sweden, the Motala hospital-based home care, was established to provide a high level of medical care on a 24-hour basis, as an alternative and a replacement to hospital care. The current study summarizes the care and organizational needs of 179 consecutive terminally ill cancer patients treated during a 10-year period. Of the patients, 70% came from acute clinics. The median time of care was 36 days. The need for help with activities of daily living was a significant predictor of the length of survival, with the greatest difference between four or less compared to five or six items (p = 0.0006). Analgesics were needed by 96% of the patients, and 78% were provided with various facilities such as hospital beds. The input of family members as primary caregivers was essential for successful care, as were security factors such as easy availability of a nurse or doctor, at any time day or night, and an immediate, guaranteed hospital bed, if needed. As many as 89% of the patients who wished to live at home until death actually did so. We conclude that hospital-based home care according to the Motala model can replace hospital care for selected patients, but only if both the patient and the family approve.

Cost analysis and ethical aspects of hospital-based home-care for terminal cancer patients.

A study was undertaken to measure the costs of caring for 20 terminally ill/dying cancer patients at home, within a hospital-based home-care system. A new method was used, by which all staff expenses were registered and the work costs per minute were calculated for each personnel category (e.g. nurses, physicians). The total number of care days amounted to 857. The average daily cost was 509 Skr. (range 87-2999), but it was higher for patients with the shortest periods of home-care ( = the dying patients). Comparisons were made between the costs of hospital-based home-care and those of hospital care in 1) a geriatric unit, 2) other somatic departments, and 3) those departments from which the patients had been referred. The costs of hospital-based home-care were 40%, 55%, and 67% lower than the three different forms of hospital care, respectively. All the patients had relatives at home and were intensely dependent on their families. The important part played by the relatives contributed to the relatively low costs. The ethical aspects of caring for dying cancer patients at home are discussed.

Work stress and job satisfaction in hospital-based home care.

The entire staff of the hospital-based home care (HBHC) at Motala (n = 35) participated in a study concerning work stress and job satisfaction. A significant number of the patients in the HBHC have advanced malignancies and most of them are terminally ill. A total of 219 questions about stress and job satisfaction were asked in a self-administered questionnaire. Only 3%-17% of the staff often or very often experienced stress factors such as high expectations, confusing orders, or lack of information. Instead, a majority stated that they often/very often experienced different aspects of job satisfaction, such as meaningfulness, security, and stimulation. Staff members stating that they often were proud/very proud of their jobs, members feeling that their skill and experience were needed, as well as staff members who often received praise from their superiors, were less prone to look for other jobs (p less than 0.01, p less than 0.05, and p less than 0.05, respectively). Those who often/very often were allowed to take initiatives of their own more often regarded their jobs as non-monotonous (p less than 0.05) and stimulating to their personal development (p less than 0.001). Despite demanding jobs with severely ill patients, most of the staff gave high ratings for different aspects of job satisfaction. This positive spirit was also reflected in the exceptionally low job turnover among them. Possible explanations may be a careful selection of personnel and an organization which both stimulates the staff's own initiatives and provides support when necessary.
