Allogeneic blood transfusions are claimed to be an independent risk factor for postoperative infections in open colorectal surgery due to immunomodulation. Leukocyte-depletion of erythrocyte suspensions has been shown in some open randomized studies to reduce the rate of postoperative infection to levels observed in nontransfused patients. Using a double-blinded, randomized design, we studied the postoperative infection rate in patients undergoing open colorectal surgery transfused with either leukocyte-depleted erythrocyte suspensions (LD-SAGM) or non-leukocyte-depleted erythrocyte suspensions (SAGM). Unselected patients (n 279) were allocated to receive LD-SAGM (n 139) or SAGM (n 140) if transfusion was indicated. Forty-five percent were transfused, yielding 48 patients in the LD-SAGM group and 64 in the SAGM group. Thirteen patients were excluded because they received one type of transfusion in spite of randomization to the other type. No significant differences in the rates of postoperative infections (P=0.5250) or postoperative complications (P=0.1779) were seen between the two transfused groups. Infection rates were 45% and 38% in the transfused groups and 21% and 23% in the nontransfused groups. No significant difference between the transfused groups was seen on any single infectious event, mortality rate, or duration of hospitalization. Leukocyte-depletion of erythrocyte suspensions transfused to patients undergoing open colorectal surgery does not reduce postoperative infection rates.

We investigated the effect of daily real-time teleconsultations for one week between hospital-based nurses specialised in respiratory diseases and patients with severe COPD discharged after acute exacerbation. Patients admitted with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) at two hospitals were recruited at hospital discharge. They were randomly assigned to intervention or control. The telemedicine equipment consisted of a briefcase with built-in computer including a web camera, microphone and measurement equipment. The primary outcome was the mean number of total hospital readmissions within 26 weeks of discharge. A total of 266 patients (mean age 72 years) were allocated to either intervention (n = 132) or control (n = 134). There was no significant difference in the unconditional total mean number of hospital readmissions after 26 weeks: mean 1.4 (SD 2.1) in the intervention group and 1.6 (SD 2.4) in the control group. In a secondary analysis, there was no significant difference between the two groups in mortality, time to readmission, mean number of total hospital readmissions, mean number of readmissions with AECOPD, mean number of total hospital readmission days or mean number of readmission days with AECOPD calculated at 4, 8, 12 and 26 weeks. Thus the addition of one week of teleconsultations between hospital-based nurses and patients with severe COPD discharged after hospitalisation did not significantly reduce readmissions or affect mortality.

BackgroundAn essential element in the treatment of patients with chronic obstructive pulmonary disease (COPD) is rehabilitation, of which supervised training is an important part. However, not all individuals with severe COPD can participate in the rehabilitation provided by hospitals and municipal training centres due to distance to the training venues and transportation difficulties. The aim of the study was to assess the feasibility of an individualized home-based training and counselling programme via video conference to patients with severe COPD after hospitalization including assessment of safety, clinical outcomes, patients’ perceptions, organisational aspects and economic aspects.MethodsThe design was a pre- and post-test intervention study. Fifty patients with severe COPD were included. The telemedicine training and counselling included three weekly supervised exercise sessions by a physiotherapist and up to two supervised counselling and training sessions in energy conservation techniques by an occupational therapist. The telemedicine videoconferencing equipment was a computer containing a screen, a microphone, an on/off switch and a volume control.ResultsThirty seven (74%) participants completed the programme, with improvements in health status assessed by the Clinical COPD Questionnaire and physical performance assessed by a sit-to-stand test and a timed-up-and-go test. There were no cases of patient fall or emergency contact with a general practitioner during the telemedicine training sessions. The study participants believed the telemedicine training and counselling was essential for getting started with being physically active in a secure manner. The business case showed that under the current financing system, the reimbursement to the hospital was slightly higher than the hospital expenditures. Thus, the business case for the hospital was positive. The organizational analysis indicated that the perceptions of the staff were that the telemedicine service had improved the continuity of the rehabilitation programme for the patients and enabled the patients’ everyday lives to be included in the treatment.ConclusionsThis study showed that home-based supervised training and counselling via video conference is safe and feasible and that telemedicine can help to ensure more equitable access to supervised training in patients with severe COPD.Trial registrationClinical Trials NCT02085187 (Date of registration 10.03.2014).
