Background In order to achieve patient adherence, individuals require different levels of information. Basic and adequate information must be provided by different health care providers to patients. Objective To assess the information level of patients with asthma and chronic obstructive pulmonary disease (COPD) and to determine the source of their information regarding the medicine they use in addition to their satisfaction, inhalation usage techniques and perception of the information providing role of health care professionals. Setting Respiratory disease clinics in Nicosia and Famagusta state hospitals and community pharmacies in North Cyprus. Method A cross-sectional multicentered observational study was carried out in respiratory disease clinics and community pharmacies. Patients' knowledge and healthcare providers' perceptions of their roles were evaluated using "The satisfaction with information about medicines scale". Evaluation of patient's inhalation techniques was performed using a validated checklist. Main outcome measure (a) Patients' knowledge of their medication and satisfaction with the information provided by health care professionals, (b) the prevalence of critical inhalation mistakes, (c) health care professionals' perceptions of their patient counseling practice. Results A total of 110 patients were evaluated, and 6 physicians and 76 pharmacists were recruited for the interview. The health care professionals reported that they talk about the action and the use of medicines with the patients. The standardized average patients' satisfaction score for action and use was 0.35 (+/- 0.21), whereas for potential side effects, it was 0.26 (+/- 0.15). Even though 92% of patients believed that they use their inhaler properly, 75% of the patients made at least one critical mistake while using the inhalation demo, which would likely affect the delivery of the medicine to the lungs. Conclusion In spite of health care professionals feeling comfortable with their counseling practices, the majority of patients reported dissatisfaction with the information they provided about medicine, and three out of four patients were making critical mistakes in the use of inhalers. More effort is warranted by health care professionals on patient education to limit critical mistakes.
