Pain management must involve treating the cause of the painwhere possible, for example appropriate use of antibiotics forinfection, fixation for fractures, spinal stabilization. Wherethe cause of pain cannot be removed entirely, treatment shouldbe directed at modifying the disease process if possible, forexample palliative radiotherapy and/or chemotherapy, bisphosphonatesfor hypercalcaemia, surgery for bowel obstruction. Attentionto a patient's physical environment is important and simplemeasures, for example use of appropriate mattresses, orthotics,and mobility or bathing aids, . . . [Full Text of this Article]

OBJECTIVE: The authors described the influence of specific medical conditions on clinical remission and response of major depression (MDD) in a clinical trial evaluating a care-management intervention among older primary-care patients. METHODS: Adults age 60 years and older were randomly selected and screened for depression. Participants were randomly assigned to Usual Care or to an Intervention with a depression care-manager offering algorithm-based care for MDD. In all, 324 adults meeting criteria for MDD were included in these analyses. Remission and response was defined by a score on the Hamilton Rating Scale for Depression <10 and by a decrease from baseline of > or =50%, respectively. Medical comorbidity was ascertained through self-report. Cognitive impairment was defined by a score <24 on the Mini-Mental State Exam (MMSE). RESULTS: In Usual Care, rates of remission were faster in persons who reported atrial fibrillation (AF) than in persons who did not report AF and slower in persons who reported chronic pulmonary disease than in persons who did not report chronic pulmonary disease; rates of response were less stable in persons with MMSE <24 than in those with MMSE > or =24. In the Intervention condition, none of the specific chronic medical conditions were significantly associated with outcomes for MDD. CONCLUSIONS: Because disease-specific findings were observed in persons who received Usual Care but not in persons who received more intensive treatment in the Intervention condition, our results suggest that the association of medical comorbidity and treatment outcomes for MDD may be determined by the intensity of treatment for depression.  相似文献

Recent New Labour policy for the ‘modernisation’ of Government places a good deal of emphasis on decentralisation. This emphasis is particularly marked in relation to the organisation of primary care. However, like hospitals and other National Health Service institutions, primary care trusts (PCTs) are subject to a substantial raft of centrally established performance targets and indicators, including those which contribute to the public award of between zero and three performance ‘stars’. This raises questions about the extent to which employees can exercise autonomy in the context of rigid top‐down directives. This paper presents findings from a study using participant observation and interviews to examine the impact of a training course aimed ostensibly at increasing employee autonomy in an English PCT. The suggestion is that attempts to make employees more autonomous can be seen as a strategy for increasing central control based upon the internalisation by the employees of centrally promulgated values. The attraction of such strategies is that they may be potentially more effective and less costly than alternative strategies of direct control. However, the study suggests that the outcome of attempts by such methods as programmes to increase employee autonomy may be very different from those intended.  相似文献

The first 150 words of the full text of this article appear below. Key points Cancer pain management services must integrate withpalliative and primary care. Pain is common in cancer and usuallyoccurs in more than one site. Careful assessment and treatmentsaimed at the causes of the pain are essential. Optimal oralpharmacotherapy manages more than 75% of patients with cancerpain. If specific anti-cancer therapy, drugs, physical andpsychological treatments fail, then more invasive therapiesshould be considered early.
