[Comorbidities in patients hospitalized due to chronic obstructive pulmonary disease. A comparative analysis of the ECCO and ESMI studies]. / Comorbilidades en pacientes hospitalizados por enfermedad pulmonar obstructiva crónica. Análisis comparativo de los estudios ECCO y ESMI.

BACKGROUNDS AND OBJECTIVES: The presence of associated diseases is very frequent in patients hospitalized due to exacerbation of COPD. We have studied the comorbidities of patients admitted due to the disease in the Spanish Internal Medicine Services and we have evaluated the variations in regards to a previous study (ECCO study) performed two years earlier. PATIENTS AND METHODS: A cross-sectional, multicenter and cohort study was performed. Patients hospitalized due to exacerbation of COPD in Spanish Internal Medicine Services were enrolled. All the patients were studied for the presence of comorbidity using the Charlson index and a questionnaire with relevant conditions not included in this index. Furthermore, spirometric data were collected on the duration of the disease or home treatment, among other variables. RESULTS: A total of 1004 patients (398 in the ECCO study and 606 in the ESMI study) were studied. Of these, 89.4% were males, with mean age of 73 years (SD: 9.5 years). The patients of the ESMI study obtain higher scores on the Charlson index (3.04 vs. 2.71; P<0.01), and had a greater prevalence of ischemic heart disease (17 vs. 22.0%; P<0.05), heart failure (26.9 vs. 35.5%; P<.002), peripheral vascular disease (12.6 vs. 17.4%; P<.02), arterial hypertension (54.8 vs. 65.6%; P<.001), diabetes mellitus (29.4 vs. 37%; P<.02) and renal failure (6.5 vs. 16.8%; P<.0001). CONCLUSIONS: This study confirms the elevated prevalence of associated diseases in patients with COPD who are admitted to the Spanish Internal Medicine Services and the increase of comorbidities.

[Study of the comorbidities in hospitalized patients due to decompensated chronic obstructive pulmonary disease attended in the Internal Medicine Services. ECCO Study]. / Estudio de las comorbilidades en pacientes hospitalizados por descompensación de la enfermedad pulmonar obstructiva crónica atendidos en los servicios de Medicina Interna. Estudio ECCO.

OBJECTIVE: Evaluate comorbidity in patients hospitalized due to COPD in the Internal Medicine services. METHODS: An observational, prospective and multicenter study. The Charlson index and a specific questionnaire were used. RESULTS: A total of 398 patients, 353 men (89%), with mean age of 73.7 years (8.9) and mean FEV(1) of 43.2% (12.5), were included. The most frequent comorbidities were: arterial hypertension (55%), arrhythmias (27%) and diabetes mellitus (26%). A total of 27% suffered heart failure, 17% coronary disease and 9% previous myocardial infarction. The number of associated chronic diseases was 3.6 (1,8). Score on Charlson index was 2.72 (2). CONCLUSIONS: The patients hospitalized due to decompensated COPD had an elevated comorbidity.

Pain in clinical oncology: patient satisfaction with management of cancer pain.

BACKGROUND: Despite effective analgesic therapy, inadequate pain control is frequently perceived by patients and caregivers. AIMS: To assess satisfaction with management of pain in cancer patients. METHODS: Between January and May 2007, a cross-sectional multicentre study was conducted in 64 Medical Oncology Departments throughout Spain. A total of 525 outpatients with oncological diseases completed a questionnaire with demographic data, characteristics and intensity of pain, and perceptions and attitudes towards pain management at the time of a routine clinical visit. Physicians also completed a questionnaire with tumour-related and treatment-related data. Cluster analysis was used to classify patients into three groups (satisfied, neither satisfied nor dissatisfied or neutral, dissatisfied) according to pain intensity and satisfaction with treatment. RESULTS: Patients satisfied with their analgesic treatment (33%) had lower pain intensities and, when regularly asked about their pain, considered their physicians to be more involved in their treatment. Neither satisfied nor dissatisfied patients (neutral) (44%) had higher mean pain intensities. Two-thirds of them achieved marked relief of their pain and also thought that physicians were aware of their situation. Dissatisfied patients (23%) had moderate to severe pain intensities, and said that they were asked less frequently about their pain, and thought that their physicians were less involved in their analgesic treatment. CONCLUSION: Physician-patient communication and information provided to patients are essential aspects of patient perceptions and attitudes towards control of cancer-related pain. Pain is seen as a condition that may be controlled but affects the capacity to lead a normal life.

Primary care nursing of coronary patients and reduction of re-infarction risk: a nested case-control study.

OBJECTIVES: To estimate the risk reduction for re-infarction achieved in primary health care centres. STUDY DESIGN: This was a case-control study nested in a cohort of coronary patients. POPULATION: Nine hundred and eighty-five coronary patients, aged less than 76 years who had survived for more than 6 months after their first acute myocardial infarction (AMI), were recruited from two public hospitals in Navarre, Spain. Cases (repeated myocardial infarction, n = 137) and controls (patients with one AMI who had not had a second infarction, [n = 137) who had not been treated with invasive procedures were extracted from this cohort and matched by gender, age, hospital and the secondary prevention time frame. OUTCOMES MEASURED: Re-infarction. RESULTS: In total, 31.4% of cases and 51.8% of controls attended the primary care nurse clinic regularly. This difference accounted for a significant reduction of the risk of re-infarction, even after adjustment for regular visits to the family physician, life styles (smoking, walking habit and dietary changes) and drug treatments (odds ratio: 0.48; 95% confidence interval: 0.26-0.89). A regular schedule of visits to the family physician showed no association with further coronary risk reduction. CONCLUSIONS: Regular attendance of coronary patients at a primary care nurse clinic is associated with a lower risk for re-infarction. Psychological rehabilitation could be the main reason for this benefit, since protection persists after adjustments for other known risk factors.
