Association between a name change from palliative to supportive care and the timing of patient referrals at a comprehensive cancer center

Purpose.

Palliative care consultation services are now available in the majority of cancer centers, yet most referrals to palliative care occur late. We previously found that the term “palliative care” was perceived by oncology professionals as a barrier to early patient referral. We aimed to determine whether a service name change to supportive care was associated with earlier referrals.

Patients and Methods.

Records of 4,701 consecutive patients with a first palliative care consultation before (January 2006 to August 2007) and after (January 2008 to August 2009) the name change were analyzed, including demographics and dates of first registration to hospital, advanced cancer diagnosis, palliative care consultation, and death. One-sample proportions tests, median tests, χ² tests, and log-rank tests were used to identify group differences.

Results.

The median age was 59 years, 50% were male, and 90% had solid tumors. After the name change, we found: (a) a 41% greater number of palliative care consultations (1,950 versus 2,751 patients; p < .001), mainly as a result of a rise in inpatient referrals (733 versus 1,451 patients; p < .001), and (b) in the outpatient setting, a shorter duration from hospital registration to palliative care consultation (median, 9.2 months versus 13.2 months; hazard ratio [HR], 0.85; p < .001) and from advanced cancer diagnosis to palliative care consultation (5.2 months versus 6.9 months; HR, 0.82; p < .001), and a longer overall survival duration from palliative care consultation (median 6.2 months versus 4.7 months; HR, 1.21; p < .001).

Conclusion.

The name change to supportive care was associated with more inpatient referrals and earlier referrals in the outpatient setting. The outpatient setting facilitates earlier access to supportive/palliative care and should be established in more centers.     

Different clinical severity of first episodes and recurrences of thrombotic thrombocytopenic purpura

The clinical course of thrombotic thrombocytopenic purpura (TTP) is characterized by recurrent disease episodes in up to 50% of cases. The clinical presentation and severity of different TTP episodes have not been systematically compared. Laboratory and clinical information from 51 patients with recurrent disease, derived from 136 patients with TTP included in the Milan TTP registry (URL: http://www.ttpdatabase.org), were used to compare mortality, symptoms and disease-related laboratory measurements in different disease episodes. The prevalence of severe neurological symptoms (coma, seizures, and focal neurological defects) was significantly lower in recurrences than in the first episode. Platelet counts and haemoglobin levels at presentation were higher in recurrences than in the first disease episode, and lactate dehydrogenase levels were lower. Also, mortality tended to be lower in the second and third disease episodes than in the first. Recurrences of TTP are generally milder than first episodes. These differences in severity should be taken into account in clinical research on TTP and in patient management.     

Sporotrichosis: success of itraconazole treatment

An 82-year-old man with hypothyroidism presented with an ulcerated nodule on the dorsum of his left hand (Figure 1). The lesion had been present for about 3 months. Similar lesions were present along the lymphatic distribution of the dorsum of his left forearm, proximal to the first lesion, as well as the dorsum of his right forearm. Laboratory findings were normal. Immune complexes, complement 3, and complement 4 were negative. A biopsy from an ulcerated nodule was taken for both histologic examination and culture. Hematoxylin and eosin sections showed a nonspecific chronic granulomatous reaction. No fungi were detected by periodic acid-Schiff stain and methenamine silver stain. Culture of tissue obtained from a skin biopsy of 1 lesion placed directly on Sabouraud agar produced colonies of Sporothrix schenckii (Figure 2). The diagnosis of lymphocutaneous sporotrichosis was confirmed.

Racemization of aspartic acid in human articular cartilage.

The rate of racemization of aspartic acid was measured in young and aged human femoral head cartilage. Normal femoral heads were obtained at postmortem, osteoarthritic specimens at operations for total hip replacement. In order to distinguish between the aspartic acid racemization in collagen from that in proteoglycan (PG), in addition to native tissue, we tested cartilage specimens from which PG had been enzymatically removed. Preliminary results indicate that there is only a very slow collagen turnover in normal adult cartilage. The same is true of residual cartilage from osteoarthritic femoral heads, indicating no rapid repair except where osteophytes are formed. Native, PG-containing cartilage, whether normal or osteoarthritic was found to have unexpectedly high racemization rates.

Chronic daily headache with migrainous features due to papilledema-negative idiopathic intracranial hypertension

Patients with the syndrome of chronic daily headache often report migrainous symptoms and consequently are diagnosed as having a primary headache syndrome. We report two cases of idiopathic intracranial hypertension causing chronic daily headache with migrainous features in the absence of associated papilledema.
