Evaluation of clinically relevant changes in patient reported outcomes in knee and hip osteoarthritis: the minimal clinically important improvement

Background: In clinical trials, at the group level, results are usually reported as mean and standard deviation of the change in score, which is not meaningful for most readers. Objective: To determine the minimal clinically important improvement (MCII) of pain, patient's global assessment of disease activity, and functional impairment in patients with knee and hip osteoarthritis (OA). Methods: A prospective multicentre 4 week cohort study involving 1362 outpatients with knee or hip OA was carried out. Data on assessment of pain and patient's global assessment, measured on visual analogue scales, and functional impairment, measured on the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) function subscale, were collected at baseline and final visits. Patients assessed their response to treatment on a five point Likert scale at the final visit. An anchoring method based on the patient's opinion was used. The MCII was estimated in a subgroup of 814 patients ( 603 with knee OA, 211 with hip OA). Results: For knee and hip OA, MCII for absolute ( and relative) changes were, respectively, ( a) -19.9 mm (-40.8%) and -15.3 mm (-32.0%) for pain; ( b) -18.3 mm ( - 39.0%) and -15.2 mm ( -32.6%) for patient's global assessment; ( c) -9.1 ( -26.0%) and -7.9 ( -21.1%) for WOMAC function subscale score. The MCII is affected by the initial degree of severity of the symptoms but not by age, disease duration, or sex. Conclusion: Using criteria such as MCII in clinical trials would provide meaningful information which would help in interpreting the results by expressing them as a proportion of improved patients.

Evaluation of clinically relevant states in patient reported outcomes in knee and hip osteoarthritis: the patient acceptable symptom state

Background: The patient acceptable symptom state ( PASS) is the value beyond which patients can consider themselves well. This concept can help in interpreting results of clinical trials. Objective: To determine the PASS estimate for patients with knee and hip osteoarthritis (OA) by assessing pain, patient's global assessment of disease activity, and functional impairment. Methods: A 4 week prospective multicentre cohort study of 1362 outpatients with knee or hip OA was carried out. Data on assessment of pain and patient's global assessment of disease, measured on visual analogue scales, and functional impairment, measured on the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) function subscale, were collected at baseline and final visits. The patients assessed their satisfaction with their current state at the final visit. An anchoring method based on the patient's opinion was used. Results: For patients with knee and hip OA, the estimates of PASS were, respectively, 32.3 and 35.0 mm for pain, 32.0 and 34.6 mm for patient global assessment of disease activity, and 31.0 and 34.4 points for WOMAC function score. The PASS varied moderately across the tertiles of baseline scores but not across age, disease duration, or sex. Conclusion: The use of PASS in clinical trials would provide more meaningful results expressed as a proportion of patients in an acceptable symptom state.

Acupressure for the in-patient treatment of nausea and vomiting in early pregnancy: A randomized control trial

Objective: The purpose of this study was to evaluate the efficacy of acupressure at the P6 point for the in-patient treatment of severe nausea and vomiting in early pregnancy. Study design: This was a prospective single-blind randomized control trial that involved 80 patients with nausea and vomiting plus ketonuria before 14 weeks of gestation. Results: There was no difference between length of stay, amount of medication, or fluid required between the acupressure and placebo groups, although acupressure reduced the number of patients who stayed >= 4 nights in the hospital. Acupressure was well tolerated and not associated with an increase in perinatal morbidity or death. Conclusion: The use of acupressure Lit the P6 point does not reduce the amount of antiemetric medication that is required, the requirement for intravenous fluid, and median duration of inpatient stay more than the use of placebo. A small reduction was seen in the number of women who required >= 4 days in the hospital. (c) 2006 Mosby, Inc. All rights reserved.

Issues of cause and control in patient accounts of Type 2 diabetes

Patients experience considerable difficulties in making and sustaining health-related lifestyle changes. Many Type 2 diabetes patients struggle to follow disease risk-management advice even when they receive extensive information and support. Drawing on a qualitative study of patients with Type 2 diabetes, the paper uses discourse analysis to examine their accounts about disease causation and disease management, and the implications for how they respond to their condition and health services advice. As it is a multifactorial disease, biomedical discourse around Type 2 diabetes is complex. Patients are encouraged to grasp the complicated message that both cause and medical outcomes related to their condition are partly, but not wholly, within their control. Discursive constructions identified from respondent accounts indicate how these two messages are deployed variously by respondents when accounting for disease causation and management. While these constructions (identified in respondent accounts as 'Up to me' and 'Down to them') are a valuable resource for patients, equally they may be deployed in a selective and detrimental way. We conclude that clear messages from health professionals about effective disease management may help patients to position themselves more effectively in relation to their condition. More importantly, they might serve to hinder the availability of inappropriate and potentially harmful patient positions where patients either relinquish responsibility for disease management or reject all input from health professionals. © The Author 2005.

Promoting the 6Cs of Nursing in Patient Assessment

Recognising the deteriorating patient is an essential nursing skill, and structured frameworks should be in place to assist effective patient assessment. The aim of this article is to encourage nurses to consider how to promote the 6Cs of nursing within such assessment. The article provides an overview of the Patient Assessment and Clinical reasoning Tool designed to facilitate the development of clinical reasoning skills and effective communication with other healthcare professionals, therebyenhancing patientcentred care.

Three-trocar laparoscopic cholecistectomy in patient with situs viscerum inversus totalis. Case report and review of the literature

Situs viscerum inversus totalis is a rare defect with a genetic predisposition, which can present difficulties in the management of abdominal pathology, especially in laparoscopic surgery (mirror-image anatomy). We report the case of a 52-year-old female with situs viscerum inversus totalis, known from pediatric age, with a medical history of colic pain in the epigastrium radiating to the right abdominal quadrant. Laparoscopic cholecistectomy was safely performed with a three trocar technique. To the best of our knowledge this is the first time that laparoscopic cholecistectomy by three trocars was performed in a patient with situs viscerum inversus. We also review the relevant literature concerning this issue.

Retrocaval mass in patient with von Recklinghausen disease. Case report

Type I Neurofibromatosis (NF1) is an autosomal-dominant inheritable disorder, with an incidence of 1:3,000, and a prevalence of 1:4,000 to 5,000. Pathogenesis is based on mutations of the NF1 gene, a tumor suppressor gene encoding a cytoplasmic protein named neurofibromin that controls cellular proliferation. Patients affected by NF1 typically present with cutaneous neurofibromas, cafè au lait spots and eye involvement, but they can also be affected by various visceral tumors, such as neurofibromas (nodular or plexiform type), gastrointestinal stromal tumors or endocrine tumors, such as pheochromocytomas. Visceral neurofibromas are often asymptomatic but when growing in size they may present with pain, palpable abdominal mass, symptoms secondary to bowel obstruction or main vessels compression, and even gastrointestinal bleeding when mucosa or submucosa are involved. In these cases surgery becomes mandatory in order to remove all neoplastic tissue. The Authors describe a case of a young man affected by NF1 with associated retrocaval abdominal mass with compression and displacement of the inferior vena cava, thus requiring a complex surgical procedure.

Ventricular Fibrillation in Patient with Multi-vessel Coronary Spasm Four Days after the Initiation of Oral Beta-blocker

We describe a case of ventricular fibrillation occurring in a patient with multi-vessel coronary spasm after the initiation of an oral beta-blocker. A 56-year-old man began to experience chest discomfort and his computed tomography revealed intermediate coronary stenoses. He was administered medications including an oral beta-blocker but suddenly collapsed while walking 4 days later. An automated external defibrillator detected ventricular fibrillation and delivered successful electrical cardioversion. An acetylcholine provocation test after stabilization of the status revealed triple-vessel coronary spasm. Beta-blockers may provoke exacerbation of coronary spasm and result in lethal arrhythmia.

Synbiotic supplementation promotes improvement of chronic diarrhea of unknown etiology in patient with chronic kidney disease and provides better outcomes in dialysis

Background: Chronic kidney disease (CKD) patients often have gastrointestinal symptoms which may result in malnutrition and a negative impact on their quality of life. Modulation of the gut microbiota can be a strategy to promote host health and homeostasis. Case report: The authors present a case of chronic diarrhea in a hemodialysis (HD) patient with an unknown etiology. After about one year and several failed interventions, synbiotic therapy was performed. The diarrhea episodes ceased after three months of daily supplementation and both biochemical and nutritional parameters improved. Synbyotic therapy promoted clinical benefits in this patient. Discussion: Therefore, this simple therapy may be a promising alternative in CKD and it should be tested in larger studies.
