Study type and design

98 Improving Asthma Care in Ministry of Health Primary Care Clinics of asthmatic patients. All asthma patients who fulfilled the criteria and received treatment at the selected health clinics during the study period were involved and sampled using convenient quota sampling. Phase 1 – Planning the intervention package In this phase, an intervention package was designed: 1. Flow Chart of Chronic Asthma Management in Adult based on GINA revised 2006 see Appendix A 2. Modified Management Approach Based on Asthma Control see Appendix B 3. Peak Expiratory Flow Rate PEFR monitoring to determine level of asthma control, and use of Peak Flow Chart during clinic visit. see Appendix C 4. Asthma Action Plan for patient see Appendix D 5. Asthma Control Handbook and Asthma Treatment Record for patient. Two weeks before starting the baseline audit Phase 2, all healthcare providers involved directly in asthma management were briefed and trained based on above interventional package, over one day session see Appendix F1. The target group of healthcare providers was: 1. Medical officers 2. Assistant medical officers 3. Nurses sister, staff nurse, community nurse Each new staff who was to get involved in the asthma management in selected clinics was trained by the existing trained healthcare providers in the clinic. These interventional package and peak flow meters were distributed and made available in all treatment and consultation rooms, where they were used to improve the asthma control. By using these tools, the healthcare providers were reminded on the steps that need to be taken if patients have partially controlled or uncontrolled asthma, and that management should be adjusted according to their level of control. Phase 2 – Baseline Audit with Simultaneous Ongoing Intervention Data collection on 500 asthmatic patients was collected from all the participating clinics. Patient attending the clinic for continuation of asthma care were selected by quota sampling, with their card stamped at the screening room see Appendix E. Age, gender, medications, and asthma symptoms as stated in ACT were self-reported by the patients using the Asthma Action Plan AAP leaflet Appendix D, assisted by the trained healthcare provider, who was responsible to measure their height and PEFR. The medical officers or assistant medical officers in the treatment or 99 Improving Asthma Care in Ministry of Health Primary Care Clinics Phase 1: Planning intervention package June – August 2008 Design and preparing of intervention package, followed by empowerment of health care providers on: 1. Flow Chart of Asthma Management 2. Modified Management Approach Based on Asthma Control 3. Peak Expiratory Flow Rate PEFR monitoring 4. Asthma Action Plan for patient including ACT 5. Asthma Control Handbook Treatment Record Phase 2: Baseline audit with simultaneous ongoing intervention August 2008 – February 2009 Pre-intervention data collection on age, gender, medication, asthma control level and PEFR 500 quota samples from 6 intervention clinics Implementation of the intervention package simultaneously: 1. Flow Chart of Asthma Management 2. Modified Management Approach Based on Asthma Control 3. Peak Expiratory Flow Rate PEFR monitoring during clinic visit 4. Asthma Action Plan for patient including ACT 5. Asthma Control Handbook Treatment Record Phase 3: Post-intervention audit March 2009 Post-intervention data on age, gender, medication, asthma control level and PEFR will be collected at 6 months post-implementation n=500 Figure 1. Flow chart of methodology 100 Improving Asthma Care in Ministry of Health Primary Care Clinics consultation rooms were required to review the AAP leaflet and management of patient were then be based on the Modified Management Approach Appendix B. This intervention was implemented throughout the 6 months study period August 2008 – February 2009. For each clinic visit, the patients were given a new AAP leaflet for them to keep record, to reinforce education and empowering. Phase 3 – Post-intervention Audit March 2009 In this phase, the same 500 asthmatic patients from the selected clinics were reviewed using the AAP leaflet, at 6 months post-implementation. Post-intervention audit data were provided to the selected health clinics involved, with feedbacks and outcome measures.

3.2 Ethical Consideration

Verbal consent was obtained prior to the patient self-assessment for data on disease severity. No identifiable particulars were collected. There was no control group in this study, as the researchers considered it unethical not to intervene in partially controlled and uncontrolled asthmatics, when encountered during the study period.

3.3 Sampling

Sample size was calculated using EpiCalc 2000, using two proportions with the power of 0.8 at a significant level of 0.05, with a change from the asthma uncontrolled from 25 to 15, the calculated sample size is 411. For this study, at least 500 samples were targetted to allow for dropout rate of 20 from the 6 clinics within the 2 districts. Sampling was done by quota sampling. Each patient was selected as respondent and was tagged stamp on treatment card, and intervened. Inclusion criteria: All asthmatic patients: 1. Aged between 13 to 60 years old. 2. Diagnosed by a medical personnel doctors medical assistants. 3. Currently attending MOH health clinics regularly in Kinta or Batang Padang district. Exclusion criteria: 1. Presenting with status asthmaticus, as such patients will be stabilised and admitted immediately. 2. Other diseases which influence bronchial symptoms andor lung function such as heart failure, chronic obstructive airway disease COAD. 101 Improving Asthma Care in Ministry of Health Primary Care Clinics
