Development and Validation of a Survey to Assess Patient-Perceived Medication Knowledge and Confidence in Medication Use

Abstract

The Okere-Renier Survey is a reliable instrument for predicting patient-perceived level of medication knowledge and confidence.

Measuring medicine-related experiences from the patient perspective: a systematic review

“…Of these, nine were multi-domain (three to ten domains), five of which examined satisfaction with different aspects of using medicines: three versions of the Treatment Satisfaction Questionnaire for Medication (TSQM; TSQM version 1.4, 39 TSQM II, 38 and TSQM-9 50 ), the Treatment Satisfaction with Medicines Questionnaire (SATMED-Q 40 ), and the Patient Satisfaction with Medication Management instrument (PSMM 51 ). Other multi-domain instruments were the Drug Therapy Concerns Questionnaire (DTC 52 ), the Okere–Reiner Survey, 53 the Living with Medicines Questionnaire (LMQ 54 ), and the Patient-Reported Outcomes Measure of Pharmaceutical Therapy for Quality of Life (PROMPT-QoL 41 ).…”

“…The Okere–Reiner Survey was reported to “clearly distinguish between patients with good and poor perceived knowledge or confidence or satisfaction”. 53 Least reported was predictive validity ( Table 4 ). The BMQ was reported to adequately distinguish patients with different illnesses and treatments 42 and to predict adherence to therapy.…”

“…The domain-specific PSM scale 57 may be useful for studies evaluating concerns about potential adverse effects of medicines. The Okere–Reiner Survey 53 is a short measure of patients’ knowledge and self-confidence with medicine use, the latter aspect not being included in other instruments, which play an important role in the medicine use experience; however, it was not derived directly from patients despite testing instrument reliability and validity. The PSMM, 51 an instrument reported to measure patients’ perceptions of medicine management, is prescriber-centered and focused on service evaluation, despite being derived directly from patient interviews and including relevant issues.…”

“…The PSMM questionnaire 51 also includes patient–provider communication problems, for instance, perceived patient burden following repetitive questioning about medicine history, often by multiple providers, and ineffective flow of medicine-related information among health professionals. 53 Most measures of patient satisfaction with consultations and patient–provider relationships 69 – 71 do not focus on medicine-related communication; hence, the instrument developed by Jenkins et al is potentially valuable as a single-domain measure. 59 Two other instruments, the SIMS 58 and the Okere–Reiner Survey, 53 also cover medicines information transfer.…”

Examining and adapting the information–motivation–behavioural skills model of medication adherence among community-dwelling older patients with multimorbidity: protocol for a cross-sectional study

“…The adherence information will be measured by using Patients’ Perceived Knowledge in Medication Use Questionnaire, which was developed by Okere et al 56. The questionnaire contains five items covering two dimensions: general knowledge in medication use and drug interaction knowledge.…”
