Understanding medication-related needs of low-literacy patients

Assessing the pharmaceutical care needs of asthmatic patients

OBJECTIVES

To measure patients' perceptions of their care needs, by developing a tool to assess these needs and evaluate its utility in community pharmacy practice.

METHOD

A survey tool comprising 37 items was developed to assess asthmatic patients' perceptions of their health-related needs, using data from literature reviews and expert opinions. The tool was piloted on 25 patients to ensure the content of the questionnaire was valid. Changes were made following piloting and the modified tool was then tested in the main study, on 101 patients from thirteen community pharmacies in Portugal. Data from this phase were subjected to factor analysis and reliability testing.

RESULTS

118 asthmatic patients were recruited, of which 101 questionnaires were eligible for analysis. From these, 40 were male (39.6%) and 61 were female (60.4%). The mean age of respondents was 41 years (sd = 19.02). The first changes made to the survey tool included the adding of items relevant to patients recruited in the pilot and the simplification of the scaling used. The survey tool was then subjected to factor analysis and reliability testing. Six scales emerged, which described the need for GP support, specialist support, pharmacist support, nurse support, other carers' support and written support. Internal consistency was good (Cronbach's coefficient alpha ranged from 0.81 to 0.93). Although there were no significant associations between educational level and other factors, other attributes influenced the communication between pharmacist and physician (chi2 = 6.972; P = 0.031). Patients with a lower level of education (up to six years) valued communication between these two professionals more than among patients with higher education. The patient's age group was associated with an expressed need for explanation of inhaler technique (chi2 = 6.494; P = 0.039). There was extended need in both oldest and youngest patients. There was a significant difference between high and low scorers to the factor 'pharmacist's role in asthma' (F1) and patients treated by either specialist or GP (chi2 = 4.935; P = 0.026). There were differences between those who were bothered by their asthma or not and their perceptions of 'Pharmacist's ideal role in asthma' (F1 & 3) (chi2 = 5.967; P = 0.051).

CONCLUSION

The tool needs further development to ensure its validity and utility in practice. This will provide greater insight into patients' perceptions of their healthcare needs, which can allow health professionals to target their interventions. Such a tool may then be used in pharmacies that intend to change their current practice, to raise pharmacists' awareness of patients' demands. Developing ways to meet those needs will ultimately lead to an increased quality service and therefore 'client' satisfaction.

Over-the-counter analgesics in older adults: a call for improved labelling and consumer education

The use of analgesics increases with age and on any given day 20-30% of older adults take an analgesic medication. Over-the-counter (OTC) analgesics are generally well tolerated and effective when taken for brief periods of time and at recommended dosages. However, their long-term use, use at inappropriately high doses, or use by persons with contraindications may result in adverse effects, including gastrointestinal haemorrhage, cardiovascular toxicity, renal toxicity and hepatotoxicity. Many OTC drugs are also available through a prescription, for a broader range of indications and for longer durations of use and wider dose ranges, under the assumption that healthcare providers will help patients make safe choices about analgesics. Safe and effective use of medications is one of the greatest challenges faced by healthcare providers in medicine. More than 60% of people cannot identify the active ingredient in their brand of pain reliever. Additionally, about 40% of Americans believe that OTC drugs are too weak to cause any real harm. As a result of a recent US FDA policy, the conversion of prescription to OTC medications will result in a 50% increase of OTC medications. To reduce the risks of potential adverse effects from OTC drug therapy in older adults, we propose that the use of analgesics will be enhanced through the use of patient and healthcare provider education, as well as improved labelling of OTC analgesics. Improved labelling of OTC analgesics may help consumers distinguish common analgesic ingredients in a wide variety of preparations and facilitate informed decisions concerning the use of OTC drugs.
