Patients' ability to read and understand dosing instructions of their own medicines - a cross sectional study in a hospital and community pharmacy setting

Determinants of medication non-adherence among patients with chronic diseases at community pharmacy settings in South Gondar Zone, Northwest Ethiopia: a multicenter cross-sectional study

Background

Medication non-adherence is a significant public health concern in managing patients with chronic diseases, and community pharmacists are on the frontline in the management of chronic medications. Chronic diseases require lifelong pharmacotherapy and understanding the determinants of medication adherence has paramount importance to develop strategies that improve medication adherence and treatment outcomes. Thus, this study aimed to assess the magnitude of medication non-adherence and its contributing factors among patients with chronic diseases attending community pharmacies in South Gondar Zone, Northwest Ethiopia.

Methods

A multicenter cross-sectional study was conducted at community pharmacies in South Gondar Zone from September 01 to October 30, 2023. Medication adherence was assessed using a structured questionnaire using the Adherence in Chronic Diseases Scale (ACDS). Statistical Package for Social Sciences (SPSS) version 25 was used for analysis. Association between the outcome variable and independent variables was performed using binary logistic regression and a p-value of <0.05 was considered statistically significant.

Results

Among three hundred and eighty six (386) study participants recruited in this study, more than half of them 222 (57.51%, 95%CI: 52.4% - 62.5%) were low adherent to their medications. Concerning determinants of medication non-adherence; the presence of side effects (AOR =2.1, 95%CI=1.33-3.29), unable to get ever counseling from community pharmacists (AOR=2.3, 95%CI= 1.46-3.58), and poor about their medications (AOR=3.1, 95% CI= 1.96-4.82) were significantly associated with patients' non-adherence to medications.

Conclusion

The medication adherence level in this study was suboptimal, with a significant proportion of the patients being non-adherent to their medications. The presence of side effects, unable to get ever counseling, and poor knowledge about their medications were statistically significant factors of poorer medication adherence. Hence, healthcare professionals, especially community pharmacists, have a crucial role in designing the schedule for health education concerning the needs of these patients in community pharmacy settings.

Antimicrobial Stewardship for Outpatients with Chronic Bone and Joint Infections in the Orthopaedic Clinic of an Academic Tertiary Hospital, South Africa

Bone and joint infections are associated with prolonged hospitalizations, high morbidity and complexity of care. They are difficult to treat, and successful therapy requires organism-specific antimicrobial therapy at high doses for a prolonged duration as recommended in standard treatment guidelines (STGs). Adherence to the treatment plan is equally important, which is enhanced with knowledge of the condition as well as appropriate antibiotics. Consequently, the aim of this study was to provide antimicrobial stewardship (AMS) services to outpatients with chronic bone and joint infections presenting to the orthopaedic clinic at a public South African tertiary hospital. A total of 44 patients participated in this study. Chronic osteomyelitis was diagnosed in 39 (89%) patients and septic arthritis in 5 (11%). The majority (43%) of infections were caused by Staphylococcus aureus followed by Pseudomonas aeruginosa (14%). Seventy-one antibiotics were prescribed at baseline with rifampicin prescribed the most (39%), followed by ciprofloxacin (23%). The majority (96%) of the antibiotics were not prescribed according to the South African STG; however, interventions were only needed in 31% of prescribed antibiotics (n = 71) since the STG only recommends empiric therapy directed against Staphylococcus aureus. Seventy-seven percent of the patients obtained a high self-reported adherence score at baseline. Consequently, there is a need to improve AMS in bone and joint infections to improve future care.

Uncovering Caregiver Concerns: 5 key issues that still remain unresolved in administration of oral medicines for children in India

INTRODUCTION

Administration devices play a very crucial role in achieving a drug's therapeutic effect. Children are often dosed with oral liquids, but dosing devices don't have the accuracy needed, putting them at risk of inaccurate and suboptimal dosing. The availability and use of administration devices may vary throughout the world. Multiple surveys in UK, Europe and Japan have shown diverging practices by parents/caregivers. The aim of the present investigation was to conduct a larger Pan-India study through a series of workshops to understand the use and challenges of traditional devices and assess the need of innovative administration devices for liquid orals in India.

METHODS

The methodology used for the workshop was contextual inquiry and survey questionnaire were used to record the responses. Parents for the workshop were recruited by advertising the survey on various social media platforms. Informed consent was taken from the parents or caregivers for their participation in the survey. Workshops were conducted pan India and both middle class and urban worker families in the occupational category were included in the study. During the workshop, the parents were briefed about the background and purpose of the study. Certain global innovative devices such as oral syringes, syringes with pacifiers were shown to the parents. Their views and opinions were taken through survey questionnaire and via interactive sessions. The questions were themed for the interactive session on 1) challenges faced, 2) willingness to use innovative devices and 3) the factors influencing their decision on the use of innovative devices.

RESULTS

Across the four regions (4 metro cities) involved in the study, 271 caregivers agreed to participate in the workshops. 17.7% administered solid dosage forms, 81.2% administered liquid dosage form and the remaining 1.1% opted for others. Traditional devices: Caregivers reported the use of measuring cups (41.4%) followed by household spoons (25.8%), droppers (15.3%), measuring spoons (2.6%), and other dosing devices (5.5%) for measuring oral liquids. 8.0% did not use any of the dosing devices as they were administrating tablets and/or capsules. The ease-of-use score was the highest for the dropper (2.67 ± 0.68) and the lowest for the measuring spoon (2.00 ± 1.00). The reported challenges were categorised into five categories which also influences the preference of using administration devices. This includes device design, user experience and usability, sociocultural factors, such as beliefs, knowledge and education, regulatory, and market/distribution. Innovative devices: The majority of the caregivers (86.7%) were not aware of any of the innovative devices shown to them. 58.7% were willing to use it if was recommended by the doctor, 1.5% of caregivers would use it on pharmacists' recommendation and 37.6% parents would use it if came along with the medicine. The criteria considered by the parents for use of the innovative devices in the descending order were Doctor's recommendation> Quality> Cost> Packed in medicine> Ease of use > Availability/accessibility. There were no differences observed among the low and high socioeconomic status of caregviers regarding the use of traditional devices, challenges faced and awareness about innovative devices. Overall, the study revealed heterogeneity in the SES for the use of administration devices in the four zones. The association of SES and opinion on the use of administration devices was demonstrated with no statistically significant interaction between caregiver SES and the use of administration devices.

CONCLUSION

The workshop revealed the prevalence of traditional dosing devices like measuring cups, household spoons among the caregivers. It highlighted key issues with the use of appropriate administration devices for correct and accurate dosing in children that remain unresolved and prevalent in India. This study reflects on the needs of the target community; thus hope will help facilitate the development of locally sustainable solutions to improve the administration of medicines in children in India.

Comparison of Patient's Satisfaction with Pharmaceutical Care Services in Ownership-Based Pharmacies in Semarang, Indonesia

Implementation of pharmacists services provided in all pharmacies must meet the standard of pharmaceutical services guidelines, including the provision of drug information. The study aims to compare the patient's perception of drug counseling services by pharmacy staff based on the type of pharmacy ownership (franchise/non-franchise) in Semarang. This research is an observational study with a cross-sectional design. Samples were taken of 286 respondents with a quota sampling technique. Data were collected using an online google form questionnaire tested for validity and reliability. The statistical analysis results used the Mann-Whitney test with a p-value of <0.05. There is no significant difference between the patient's perception of the drug information counseling services by pharmacy staff at the franchise or non-franchise pharmacies in Semarang with a p-value of 0.264. This study also found that the standard information given by pharmacy staff is healthy eating and education about antibiotics used in the common cold. In addition, only 55% of respondents were sure that the pharmacy staff who gave them drug information in pharmacies was a pharmacist. Consequently, we humbly recommend that pharmacists consistently wear their pharmacist identification.

The extent of community pharmacists' involvement in detecting and resolving Drug Related Problems (DRPs) in prescriptions – A real time study from Sri Lanka

Background

Appropriate medication use is necessary to ensure patient safety. Drug Related Problems (DRPs) could result in patient harm.

Purpose

To assess the prevalence and types of DRPs in prescriptions, and the proportion of DRPs detected and resolved by community pharmacists during dispensation of prescriptions in a selected community pharmacy.

Methods

A prospective, cross-sectional study was conducted in a selected community pharmacy in Colombo, Sri Lanka, where one researcher reviewed for DRPs in systematically selected prescriptions (N = 400), and another directly observed the frequency of DRPs identified by community pharmacists in the same set of prescriptions. Actions taken by pharmacists on resolving DRPs were also documented. DRPs were classified according to a slightly modified version of Pharmaceutical Care Network Euro pe classification V8.01. Descriptive and comparative data analysis were performed using SPSS database V.21. P < 0.05 was considered as significant.

Results

Among 1986 medications, a total of 1211 DRPs were identified by researchers, of which only 441 DRPs were detected by community pharmacists who participated in the study (N = 24). DRPs identified by the researcher were related to medication selection (N = 15), medication form (N = 1), dose selection (N = 817), duration of treatment (N = 128), incomplete prescriptions (N = 128), and other (outdated prescriptions, missing unit of measurements, and ambiguous names of medications that could not be read by both community pharmacists and researcher) (N = 122) of which only one, one, 394, 13, five, and 27 were identified by pharmacists, respectively. Among 441 DRPs identified by pharmacists, 406 were resolved by them. Most DRPs were self-resolved by pharmacists themselves (367/406), while patients were also sent back to the prescriber (13/406), and some dispensation of medications to patients were refused (9/406).

Conclusion

Among the DRPs frequently observed in the sample of community prescriptions, the community pharmacists identified significantly fewer DRPs in relation to each type identified by the researcher, and pharmacists missed some, including incomplete prescriptions, that had potential to harm. Systematic and sustainable training of pharmacists on performing a preliminary prescription review and continuous education programs must be implemented to improve community pharmacist dispensing practices in this community.

Developing and user testing new pharmacy label formats-A study to inform labelling standards

Background

Dispensed prescription medicine labels (prescription labels) are important information sources supporting safe and appropriate medicines use.

Objective

To develop and user test patient‐centred prescription label formats.

Methods

Five stages: developing 12 labels for four fictitious medicines of varying dosage forms; diagnostic user testing of labels (Round 1) with 40 consumers (each testing three labels); iterative label revision, and development of Round 2 labels (n = 7); user testing of labels (Round 2) with 20 consumers (each testing four labels); labelling recommendations. Evaluated labels stated the active ingredient and brand name, using various design features (eg upper case and bold). Dosing was expressed differently across labels: frequency of doses/day, approximate times of day (eg morning), explicit times (eg 7 to 9 AM), and/or explicit dosing interval. Participants’ ability to find and understand medicines information and plan a dosing schedule were assessed.

Results

Participants demonstrated satisfactory ability to find and understand the dosage for all label formats. Excluding active ingredient and dosing schedule, 14/19 labels (8/12 in Round 1; 6/7 in Round 2) met industry standard on performance. Participants’ ability to correctly identify the active ingredient varied, with clear medicine name sign‐posting enabling all participants evaluating these labels to find and understand the active ingredient. When planning a dosing schedule, doses were correctly spaced if the label stated a dosing interval, or frequency of doses/day. Two‐thirds planned appropriate dosing schedules using a dosing table.

Conclusions

Effective prescription label formatting and sign‐posting of active ingredient improved communication of information on labels, potentially supporting safe medicines use.

Patient and Public Involvement

Consumers actively contributed to the development of dispensed prescription medicine labels. Feedback from consumers following the first round was incorporated in revisions of the labels for the next round. Patient and public involvement in this study was critical to the development of readable and understandable dispensed prescription medicine labels.

Continuous medication monitoring: A clinical model to predict adherence to medications among chronic kidney disease patients

BACKGROUND

An adherence model is required to optimise medication management among chronic kidney disease (CKD) patients, as current assessment methods overestimate the true adherence of CKD patients with complex regimens. An approach to assess adherence to individual medications is required to assist pharmacists in addressing non-adherence.

OBJECTIVE

To develop an adherence prediction model for CKD patients.

METHODS

This multi-centre, cross-sectional study was conducted in 10 tertiary hospitals in Malaysia using simple random sampling of CKD patients with ≥1 medication (sample size = 1012). A questionnaire-based collection of patient characteristics, adherence (defined as ≥80% consumption of each medication for the past one month), and knowledge of each medication (dose, frequency, indication, and administration) was performed. Continuous data were converted to categorical data, based on the median values, and then stratified and analysed. An adherence prediction model was developed through multiple logistic regression in the development group (n = 677) and validated on the remaining one-third of the sample (n = 335). Beta-coefficient values were then used to determine adherence scores (ranging from 0 to 7) based on the predictors identified, with lower scores indicating poorer medication adherence.

RESULTS

Most of the 1012 patients had poor medication adherence (n = 715, 70.6%) and half had good medication knowledge (n = 506, 50%). Multiple logistic regression analysis determined 4 significant predictors of adherence: ≤7 medications (constructed score = 2, p < 0.001), ≤3 co-morbidities (constructed score = 1, p = 0.015), absence of complementary/alternative medicine use (constructed score = 1, p = 0.003), and knowledge score ≥80% (constructed score = 3, p < 0.001). A higher total constructed score from the prediction model indicated a higher likelihood of adherence (odds ratio [OR]: 2.41; 95% confidence interval [CI]: 2.112-2.744; p < 0.001). The area under the receiver operating characteristic (ROC) curve of the developed model (n = 677) had good accuracy (ROC: 0.867, 95% CI: 0.840-0.896; p < 0.001). The validated model (n = 335) also had good accuracy (ROC: 0.812, 95% CI: 0.765-0.859; p < 0.001). There was no significant difference between the development and validation groups (p = 0.11, Z-value:1.62, standard error: 0.034).

CONCLUSION

The score constructed from the medication adherence prediction model for CKD patients had good accuracy and could be useful for identifying patients with a higher risk of non-adherence, to ensure optimised adherence management.

Are medications safely used by residents in elderly care homes? - A multi-centre observational study from Sri Lanka

BACKGROUND

Most residents in elderly care homes in Sri Lanka do not receive formal, on-site, patient care services.

OBJECTIVE

To evaluate the appropriateness of prescribing, dispensing, administration, and storage practices of medication used by residents in selected elderly care homes in Colombo District, Sri Lanka.

METHODOLOGY

This was a prospective, cross-sectional, multi-center study of 100 residents with chronic, non-communicable diseases, who resided in nine selected elderly care homes in Sri Lanka. Medication histories were obtained from each resident/caregiver and the appropriateness of medications in their current prescription was reviewed using standard treatment guidelines. Prescriptions were cross-checked against respective dispensing labels to identify dispensing errors. Medication administration was directly observed on two separate occasions per resident for accuracy of administration, and matched against the relevant prescription instructions. Medication storage was also observed in terms of exposure to temperature and sunlight, the suitability of container, and adequacy of separation if using multiple medications.

RESULTS

The mean age of residents was 70±10.5 years and the majority were women (72%). A total of 168 errors out of 446 prescriptions were identified. The mean number of prescribing errors per resident was 1.68±1.23 [median, 2.00 (1.00-3.00)]. Inappropriate dosing frequencies were the highest (37.5%;63/168), followed by missing or inappropriate medications (31.5%;53/168). The mean number of dispensing errors per resident was 15.9±13.1 [median, 14.0 (6.00-22.75)] with 3.6 dispensing errors per every medication dispensed. Mean administration errors per resident was 0.95±1.5 [median, 0.00 (0.00-1.00)], with medication omissions being the predominant error (50.5%;48/95). Another lapse was incorrect storage of medications (143 storage errors), and included 83 medications not properly separated from each other (58.0%).

CONCLUSION

Multiple errors related to prescribing, dispensing, administration, and storage were identified amongst those using medication in elderly care homes. Services of a dedicated consultant pharmacist could improve the quality of medication use in elderly care homes in Sri Lanka.

The Need to Strengthen the Role of the Pharmacist in Sri Lanka: Perspectives

The role of the pharmacist in healthcare has evolved greatly over the last half-century, from dispensing to providing direct patient-oriented activities not associated with dispensing. However, pharmacist-led healthcare services in Sri Lanka must undergo reform to fully take advantage of their expertise and training in medicine management and related outcomes in Sri Lankan patients. As befits a profession's role development and value, professional and educational standards for pharmacists need ongoing development and growth. Currently, university curricula and continuing professional education in Sri Lanka require further development and optimisation to provide the theoretical and practical knowledge and skills regarding quality use of medicines and patient-oriented care. Furthermore, pharmacists' roles in Sri Lankan hospital and community pharmacist settings need to be recognised and should include the pharmacist as an integral part of the multidisciplinary healthcare team in Sri Lanka. Studies from developed countries and some developing countries have demonstrated that expanded pharmacists' roles have had a significant positive cost-effective impact on the population's health. Therefore, the availability of qualified Sri Lankan pharmacists trained to deliver expanded professional services accompanied by greater pharmacist integration into healthcare delivery is crucially important to ensure quality use of medicines within the Sri Lankan healthcare system and optimise the medication-related needs of Sri Lankans.
