Cancer patients hospitalised for palliative reasons. Symptoms and needs presented at a university hospital.

The aim of this study was to identify patients in need of palliative care in 11 different care units with a total of 256 beds at Linköping University Hospital and to look at their overall situation with respect to assessed symptom control and quality of life. There were 46 patients fulfilling the two criteria of incurable cancer and need for palliative care, and each was assessed with the aid of a questionnaire (five oral questions on life situation) and a single visual analogue scale (VAS) about their overall quality of life (QoL). Each patient also assessed him- or herself on the Edmonton Symptom Assessment Scale (ESAS). Total ESAS scores ranged from 20 to 639 mm (median 211). Median VAS scores (100 mm = greatest symptom severity) were as follows: nausea 6 mm, pain 9 mm, anxiety 17 mm, depression 18 mm, drowsiness 35 mm, activity 38 mm, appetite 45 mm, and sensation of well-being 46 mm. The median score for QoL was 47 and correlated well with the total ESAS score. Thirty-seven patients answered the open question "What in your current situation troubles you the most?". Seven patients answered "nothing", and 10 said "the present symptoms". Twenty patients had different concerns (existential, social, and psychological). The low number of hospitalised patients found reflects a well-functioning hospital-based home-care unit. Reduced appetite, sensation of well-being and activity were dominant, while pain and nausea were less intense. The simple QoL-VAS seemed to be comparable to ESAS, which is more useful for assessing each single symptom. The non-physical dimensions need more attention in the future in order to achieve totally satisfactory palliative care.

Screening for iron overload using transferrin saturation.

People with parenchymal iron overload exhibit an elevated serum iron concentration and a raised transferrin (TIBC) saturation early in the course of the disease. They can therefore be detected by simple laboratory tests before organ damage has occurred. In this study running for 2 months, 10512 samples from approximately 8750 patients and blood donors were examined in a county hospital in Central Sweden. Abnormal TIBC saturation (greater than 70%) was found in 1.7% of the samples. This abnormality was caused by physiological fluctuations in serum iron in 44%, liver disease in 22%, blood disorder in 10%, iron therapy in 10.5% and parenchymal iron overload in 11.5%. The diagnosis of iron overload was confirmed by measuring the serum ferritin concentration and by performing the desferrioxamine test, liver biopsy, quantitative phlebotomy and family studies including HLA typing. We found a prevalence of iron overload of 0.24%. This figure is almost certainly too low because some affected patients were probably lost because of TIBC desaturation induced by inflammatory conditions.

Prevalence of iron overload in central Sweden.

An increase in the iron content of food may be harmful to people with genetic hemochromatosis. We studied the prevalence of this disorder in Sweden, which is the country with the world's highest iron fortification of food. Serum ferritin and transferrin (TIBC) saturation levels were used as initial screening methods. Three (0.5%) of 623 males aged 30-39 years were found to have genetic hemochromatosis. Family studies revealed 10 additional homozygotic family members. A prevalence of 0.5% of homozygotes (q2) implies a gene frequency (q) of 6.9% or a heterozygote frequency (2 x Q) of 13.8%. The high gene frequency may be explained by a possible genetic advantage of heterozygotes in the past. We conclude that idiopathic hemochromatosis is not as rare as previously thought. Affected persons should be detected and treated before irreversible organ damage occurs. This study demonstrates that serum ferritin levels together with TIBC saturation levels are adequate methods for screening populations.

Preclinical hemochromatosis in a population on a high-iron-fortified diet.

Three hundred forty-seven (96.4%) of all persons aged 30 to 39 years were screened with serum iron and iron binding capacity measurements to determine the incidence of hemochromatosis in a population. No women had signs of iron overload; however, nine men (5%) had persistenly elevated serum iron levels. In four men (2%), increased iron stores was found with a distribution like that in the early stages of hemochromatosis. In combination with recent findings of clinical hemochromatosis at our hospital, this study suggests that this condition is not as rare as has been reported earlier.

Symptom assessment in advanced palliative home care for cancer patients using the ESAS: clinical aspects.

UNLABELLED: Four hundred and thirty-one cancer patients were assessed with the ESAS and a VAS-QoL at admission to Hospital-based home care (HBHC) and subsequently. RESULTS: Pain and nausea were well-controlled (mean 2.5 and 1.8) whereas patients were less satisfied with appetite, activity and sense of well-being. Dyspnoea and anxiety (lung cancer, p<0.001 and p<0.01) and pain (prostate cancer, p<0.01), were related to diagnosis while activity, drowsiness, appetite and well-being to survival (p<0.05 to p<0.001). The correlations between individual symptoms and well-being were low (0.2-0.5), whereas the correlation between well-being and the Symptom Distress Score (SDS) was 0.76. "Well-being" was a better word to use than QoL. DISCUSSION: ESAS is useful in HBHC and data show that symptoms other than merely pain and nausea are of importance. As the global measurement (one VAS) of well-being has a high correlation with SDS, this single measurement may be clinically adequate for quality assurance of symptom control in dying cancer patients.
