SMS Reminder to Assess Adherence

• Adherence to Spiriva HandiHaler Over Time [ Time Frame: Baseline, Week 8, Week 12, Week 16, Week 20 and Week 24 ] [ Designated as safety issue: No ]
  Adherence was defined as percentage of documented applications of Spiriva HandiHaler as compared to the regularly planned seven applications during the week before questioning the patients. Patients in the SMS reminder group and in the control group were asked via SMS how often they had used Spiriva HandiHaler during the last week and were requested to call the IVR system to provide their response. Baseline was defined as week 4.
  
  

• Change From Baseline in Adherence to Spiriva HandiHaler Over Time [ Time Frame: Week 8, Week 12, Week 16, Week 20 and Week 24 ] [ Designated as safety issue: No ]
  Adherence was defined as percentage of documented applications of Spiriva HandiHaler as compared to the regularly planned seven applications during the week before questioning the patients. Patients in the SMS reminder group and in the control group were asked via SMS how often they had used Spiriva HandiHaler during the last week and were requested to call the IVR system to provide their response. Baseline was defined as week 4.
  
  
• Response Rate Regarding Adherence [ Time Frame: 24 weeks ]
  Adherence was dichotomised into yes and no at the end of study depending on whether the percentage of adherence was at least 80 percent or less than 80 percent, respectively. Patients who did not respond to the SMS/ IVR system to provide information about the actual number of inhalations were considered with 0 percent adherence.
  
  
• Patients Compliance With SMS System [ Time Frame: 24 weeks ]
  Compliance was defined as the percentage of patients answers to the IVR system as compared to the number of SMS automatically sent to the patients by the SMS/ IVR system asking for the number of Spiriva HandiHaler applications.
  
  
• Patients Assessment of Usefulness of the SMS System [ Time Frame: Visit 2 (12 weeks) and visit 3 (24 weeks) ]
  Only patients in the SMS reminder group were asked to assess the usefulness of the SMS system by the categories very helpful, helpful and not helpful.
  
  
• Physicians Assessment of Usefulness of the SMS System [ Time Frame: Visit 2 (12 weeks) and visit 3 (24 weeks) ]
  Only physicians of patients in the SMS reminder group were asked to assess the usefulness of the SMS system by the categories very helpful, helpful and not helpful.
  
  
• Physicians Recommendation of the SMS System [ Time Frame: Visit 2 (12 weeks) and visit 3 (24 weeks) ]
  Only physicians of patients in the SMS reminder group were asked if they would recommend the SMS system (no, yes, don't know)
  
  
• Patients Satisfaction With SMS System [ Time Frame: Visit 2 (12 weeks) and visit 3 (24 weeks) ]
  Only patients in the SMS group were asked to assess their satisfaction with the SMS system by assigning German school grades 1=very good, 2=good, 3=satisfactory, 4=sufficient, 5=deficient, 6=insufficient.
