It was postulated that home hospitalisation (HH) of selected chronic obstructive pulmonary disease (COPD) exacerbations admitted at the emergency room (ER) could facilitate a better outcome than conventional hospitalisation.To this end, 222 COPD patients (3.2% female; 71¡10 yrs (mean¡SD)) were randomly assigned to HH (n=121) or conventional care (n=101). During HH, integrated care was delivered by a specialised nurse with the patient9s free-phone access to the nurse ensured for an 8-week follow-up period.Mortality (HH: 4.1%; controls: 6.9%) and hospital readmissions (HH: 0.24¡0.57; controls: 0.38¡0.70) were similar in both groups. However, at the end of the follow-up period, HH patients showed: 1) a lower rate of ER visits (0.13¡0.43 versus 0.31¡0.62); and 2) a noticeable improvement of quality of life (D St George9s Respiratory Questionnaire (SGRQ), -6.9 versus -2.4). Furthermore, a higher percentage of patients had a better knowledge of the disease (58% versus 27%), a better self-management of their condition (81% versus 48%), and the patient9s satisfaction was greater. The average overall direct cost per HH patient was 62% of the costs of conventional care, essentially due to fewer days of inpatient hospitalisation (1.7 ¡ 2.3 versus 4.2 ¡ 4.1 days).A comprehensive home care intervention in selected chronic obstructive pulmonary disease exacerbations appears as cost effective. The home hospitalisation intervention generates better outcomes at lower costs than conventional care.

Although exacerbation of chronic obstructive pulmonary disease (COPD) is important in terms of health and costs, there is little information about which are the risk factors. We estimated the association between modifiable and nonmodifiable potential risk factors of exacerbation and the admission for a COPD exacerbation, using a case-control approach. Cases were recruited among admissions for COPD exacerbation during 1 yr in four tertiary hospitals of the Barcelona area. Control subjects were recruited from hospital's register of discharges, having coincided with the referent case in a previous COPD admission but being clinically stable when the referent case was hospitalized. All patients completed a questionnaire and performed spirometry, blood gases, and physical examination. Information about potential risk factors was collected, including variables related to clinical status, characteristics of medical care, medical prescriptions, adherence to medication, lifestyle, quality of life, and social support. A total of 86 cases and 86 control subjects were included, mean age 69 yr, mean FEV(1) 39% of predicted. Multivariate logistic regression showed the following risk (or protective) factors of COPD hospitalization: three or more COPD admissions in the previous year (odds ratio [OR] 6.21, p = 0.008); FEV(1) (OR 0.96 per percentual unit, p < 0.0005); underprescription of long-term oxygen therapy (LTOT) (OR 22.64, p = 0.007); and current smoking (OR 0.30, p = 0.022). Among a wide range of potential risk factors we have found that only previous admissions, lower FEV(1), and underprescription of LTOT are independently associated with a higher risk of admission for a COPD exacerbation.

In conclusion, one third of severe COPD patients in our study reported a level of physical activity lower than the equivalent to walking less than 15 min x d(-1). Apart from sociodemographic variables, comorbidity, health-related quality of life, and long-term oxygen therapy were the only factors independently associated with a low level of physical activity.

Abstract. Objective:To evaluate the indicators of activity and quality within the emergency department (ED) during a resident physicians' strike. Methods: This was an observational study comparing a strike period (SP) and a non-strike period (NSP) in the ED of a 1,000-bed tertiary care teaching hospital in Barcelona, Spain, with an annual census of 100,000 emergency visits. During a period of nine nonconsecutive days, the resident physicians were on strike. Emergency visits were handled by staff members. Data were compared between all patients treated in the ED during the SP and those treated during the NSP, matched by the weekday. The authors compared lengths of stay (LOSs), rates of use of laboratory tests and radiology procedures, numbers of patient walkouts, patient/physician ratios, emergency hospital admission rates, home discharge rates, unscheduled return rates, and mortality rates. Results:The two groups (SP 2,610 patients and NSP 3,634 patients) were comparable in terms of average daily attendance rate (SP: 290 Ϯ 12 vs NSP: 302 Ϯ 21; p = 0.13), elective hospital admission rate, and severity of illness. Statistically significant differences were found in terms of mean total patients' LOS (SP: 206.75 Ϯ 12.27 vs NSP: 235.10 Ϯ 27.08 minutes; p < 0.001), number of laboratory tests per patient (SP: 0.30 Ϯ 0.05 vs NSP: 0.38 Ϯ 0.04; p < 0.001), and radiographs per patient (SP: 0.78 Ϯ 0.06 vs NSP: 0.88 Ϯ 0.09; p = 0.021). Conclusions: This study demonstrated that replacing residents with staff physicians resulted in fewer laboratory tests ordered, fewer radiographs ordered, and shorter lengths of stays in the ED.
