Comprehensive care programme for patients with chronic obstructive pulmonary disease: a randomised controlled trial.

BACKGROUND: There have been no randomised controlled trials that specifically evaluate the effect of a comprehensive programme with multidisciplinary input on patients who have just been discharged from hospital after treatment of acute exacerbation of COPD (AECOPD). The aim of this study was to assess whether a comprehensive care programme would decrease hospital readmissions and length of hospital stay (LOS) for patients with COPD. METHODS: Patients discharged from hospital after an episode of AECOPD were randomised to an intervention group (IG) or usual care group (UG). The IG received a comprehensive, individualised care plan which included education from a respiratory nurse, physiotherapist support for pulmonary rehabilitation, 3-monthly telephone calls by a respiratory nurse over 1 year, and follow-up at a respiratory clinic with a respiratory specialist once every 3 months for 1 year. The UG were managed according to standard practice. The primary outcome was hospital readmission rate at 12 months. RESULTS: 180 patients were recruited (IG, N=90; UG, N=90; mean±SD age 74.7±8.2 years, 172 (95.6%) men; mean±SD FEV1 45.4±16.6% predicted). At 12 months, the adjusted relative risk of readmission was 0.668 (95% CI 0.449 to 0.995, p=0.047) for the IG compared with the UG. At 12 months, the IG had a shorter LOS (4.59±7.16 vs 8.86±10.24 days, p≤0.001), greater improvement in mean Modified Medical Research Council Dyspnoea Scale (-0.1±0.6 vs 0.2±0.6, p=0.003) and St George's Respiratory Questionnaire score (-6.9±15.3 vs -0.1±13.8, p=0.003) compared with the UG. CONCLUSIONS: A comprehensive COPD programme can reduce hospital readmissions for COPD and LOS, in addition to improving symptoms and quality of life of the patients.

The effect of music during bronchoscopy: A meta-analysis.

Bronchoscopy is considered a stressful procedure performed on patients. Hence, the use of music to ease the anxiety of patients has been examined in various studies, but the results have been inconclusive. The aim of this review is to synthesize the findings of previous studies on the effects of music therapy on the physiological outcomes of patients undergoing bronchoscopy. An electronic database search was performed to identify the literature. Random-effects model was used to combine the results, and meta-regression was used to explore the heterogeneity. Seven studies with 829 subjects were included. Results showed that the combined mean differences (95% confidence interval) for systolic and diastolic blood pressure were -11.99 (-15.82, -6.57) and -4.84 (-7.78, -1.90) mm Hg, respectively, whereas that for heart rate was -10.57 (-16.63, -4.51) beats per minute. In conclusion, listening to music reduced blood pressure and heart rate among patients undergoing bronchoscopy.

COPD care programme can reduce readmissions and in-patient bed days.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common disease worldwide with significant morbidity and mortality. AIM: To investigate the effect of a comprehensive COPD management programme in decreasing COPD readmissions 1 year before and 1 year after the programme. METHOD: 185 (166 males) patients admitted for acute exacerbation of COPD (AECOPD) were recruited between September 2010 and December 2012. COPD care team provided crisis support and maintenance therapy for the COPD patients for a total of 16 weeks. The protocol included COPD clinic run by respiratory physicians, COPD education and nurse clinics by respiratory nurses, out-patient pulmonary rehabilitation programme by physiotherapists, fast track doctor's clinic, telephone hotline for patients and nurse telephone calls to patients. Readmissions over a period of 1 year were assessed. RESULTS: The mean (SD) age of the subjects and FEV1 % predicted normal were 76.9 ± 7.37 yrs and 44.4 ± 20.7% respectively. 40 (21.6%) patients required non-invasive positive pressure ventilation during the recruitment admission. Admissions for AECOPD decreased from 2.39 ± 2.05 one year before programme to 1.65 ± 2.1 one year after programme (mean difference 0.75 ± 2.11 episodes, p < 0.001). The length of hospital stay was reduced from 12.17 ± 9.14 days one year before programme to 9.09 ± 12.1 days one year after the programme (mean difference 3.09 ± 12.1 days, p < 0.001). The FEV1 percentage predicted and quality of life measured by St George's Respiratory Questionnaire showed no significant improvement at 16 weeks after recruitment into the programme as compared to at 6 weeks. CONCLUSION: COPD care programme is effective in decreasing readmissions and length of hospital day for COPD patients.

An adjunct intervention for management of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

OBJECTIVES: Application of transcutaneous electrical nerve stimulation over acupuncture points (Acu-TENS) is a noninvasive intervention that has recently been shown to alleviate dyspnea in patients with stable chronic obstructive pulmonary disease (COPD). This case report aims to explore the role of Acu-TENS in patients diagnosed with COPD during the acute exacerbation. STUDY DESIGN: The study design was a case report. SETTING: The study was conducted in an inpatient setting. SUBJECT: The subject was a 74-year-old man admitted to the hospital due to acute exacerbation of COPD (AECOPD). INTERVENTION: Treatment consisted of application of TENS on EX-B1 (Dingchuan) for 45 minutes. OUTCOME MEASURES: Oxygen saturation, heart rate, and dyspnea score were measured before, immediately after, and 45 minutes after Acu-TENS intervention. Other than the physiologic measures, 10 mL of venous blood was taken from the cubital vein for assessment of ß-endorphin level, white blood cell count, tumor necrosis factor-α (TNF-α), and C-reactive protein (CRP) level before and immediately postintervention. RESULTS: Postintervention, improved oxygen saturation, and reduction in heart rate and dyspneic sensation were observed accompanied by a raised blood ß-endorphin level but the level of white blood cell count, TNF-α, and CRP remain unchanged. CONCLUSIONS: Application of 45 minutes Acu-TENS appeared to alleviate symptoms in a patient with AECOPD. The role of adjunctive Acu-TENS therapy during acute exacerbation warrants further investigation.

Effect of 4 weeks of Acu-TENS on functional capacity and beta-endorphin level in subjects with chronic obstructive pulmonary disease: a randomized controlled trial.

Our recent studies showed that one session of transcutaneous electrical nerve stimulation on acupoints (Acu-TENS) improved forced expiratory volume in 1s (FEV(1)) in patients with chronic obstructive pulmonary disease (COPD). This study investigated the effect of 4-week Acu-TENS on physical and psychosocial function in these patients. Twenty-eight patients were randomly allocated to receive 4-weeks of 45-min, 5-days/week, of either Acu-TENS (over Dingchuan), Placebo-TENS (same protocol without electrical output), or Sham-TENS (over the patellae). Variables measured before and after intervention included FEV(1), forced vital capacity (FVC), 6-min walk distance (6MWD), St. George's Respiratory Questionnaire score (SGRQ), beta-endorphin and blood inflammatory marker levels. Only the Acu-TENS group attained significant improvement in FEV(1) (p=0.046), physical activity (p=0.007) and total SGRQ score (p=0.028). The increase in beta-endorphin (p=0.012) correlated positively with the improvement in FEV(1) (r=0.526, p=0.008). To conclude, 4 weeks of Acu-TENS improved the functional capacity of patients with COPD, probably due to the bronchodilation induced by beta-endorphin elevation.

Effect of Acu-TENS on post-exercise expiratory lung volume in subjects with asthma-A randomized controlled trial.

This study examined the effect of transcutaneous electrical nerve stimulation applied over acupoints (Acu-TENS) on forced expiratory volume, in patients with asthma, after exercise. Thirty subjects were randomly assigned to three groups. Group 1 received Acu-TENS over acupuncture points Lieque and Dingchuan for 45 min prior to a symptom-limited treadmill exercise test. Group 2 had Acu-TENS similarly applied prior to and throughout the exercise test. Group 3 mimicked Group 1 but without any electrical output from the device. Forced expiratory volume in one second (FEV(1)) and forced vital capacity (FVC) were recorded before, immediately after and at 20-min intervals post-exercise for 1h. Immediately after exercise, FEV(1) and FVC rose in Group 2 (p=0.015), but decreased in Group 1 and more so in Group 3. The differences became even more marked at 20, 40 and 60 min. Adjunctive Acu-TENS therapy appears to reduce decline of FEV(1) following exercise training in patients with asthma.
