Drug-Drug interaction among admitted patients at primary, district and referral hospitals' medical wards in East Gojjam Zone, Amhara Regional State, Ethiopia

Potential drug-drug interaction and its determinants among patients with cancer receiving chemotherapy in oncology centres of Northwest Ethiopia: an institutional-based cross-sectional study

OBJECTIVE

The study was conducted to assess potential drug-drug interactions (PDDIs) and its determinants among patients with cancer receiving chemotherapy.

DESIGN AND SETTING

An institutional-based cross-sectional study was used. This study was conducted from 1 June 2021 to 15 December 2021, in Northwest Ethiopia oncology centres.

PARTICIPANTS

All eligible patients with cancer received a combination of chemotherapy.

OUTCOMES

The prevalence and severity of PDDIs were evaluated using three drug interaction databases. Characteristics of participants were presented, arranged and summarised using descriptive statistics. The predictors and outcome variables were examined using logistic regression. The cut-off point was a p value of 0.05.

RESULTS

Of 422 patients included in the study, 304 patients were exposed to at least one PDDI with a prevalence of 72.1% (95 % CI: 68% to 76%) using three drug interaction databases. There were varied reports of the severity of PDDI among databases, but the test agreement using the kappa index was 0.57 (95% CI: 0.52 to 0.62, p=0.0001) which is interpreted as a moderate agreement among three databases. Patients aged ≥50 years old had the risk to be exposed to PDDI by odds of 3.1 times (adjusted OR (AOR)=3.1, 95% CI (1.8 to 5.3); p=0.001) as compared with patients <50 years old. Similarly, patients with polypharmacy and comorbidity were more likely to be exposed to PDDI than their counterparts (AOR=2.4, 95% CI (1.4 to 4.1); p=0.002 and AOR=1.9, 95% CI (1.1 to 3.4); p=0.02, respectively).

CONCLUSION

The main finding of this study is the high prevalence of PDDI, signifying the need for strict patient monitoring for PDDIs among patients with cancer receiving chemotherapy. We suggest the use of at least three drug databases for quality screening. Patients with an age ≥50 years old, polypharmacy and comorbidity were significantly associated with PDDIs. The establishment of oncology clinical pharmacists and computerised reminder mechanisms for PDDIs through drug utilisation review is suggested.

Determinants t of patient satisfaction with pharmacy services at Felege Hiwot comprehensive specialized hospital, Bahir Dar, Ethiopia

Background

Patients have explicit desire for quality services when they visit health institutions. Patient satisfaction is a primary means of measuring the effectiveness of healthcare delivery. However, inadequate discovery of their needs may result in patient dissatisfaction. Patients who are satisfied with pharmaceutical care are likely to adherence, seeking for medical attentions and take medications properly. Providing better access to quality pharmacies is a way to improve patient satisfaction with healthcare services.

Study objective

The study was aimed to assess patient satisfaction with pharmacy services at Felege Hiwot Comprehensive Specialized Hospital (FHCSH).

Methods and materials

An institution-based cross-sectional study design was conducted at FHCSH from 1 May 2021 to 30 October 2021. Data were collected by interview with structured questionnaires. Then the data were coded, entered, and then analyzed by SPSS version 23. The association between predictors and outcome was measured using bivariate logistic regression.

Result

In this study, 384 study participants were included. Majority of the participants were males (55.37%, N=227). The overall satisfaction score of the participants of this study was 65.37%. In our study, clients showed greater satisfaction towards pharmacists' commitment to correct myths (92%), pharmacist availability (88.78), and cleanliness (87.8%). Multivariate analysis indicated physical restriction [adjusted odds ratio (AOR)=6:95%; 95% CI (2.98, 25.9)] and rural residence [AOR=2.43; 95% CI (1.71, 9.6)] had significant association with pharmacy service dissatisfaction. Among the quality pharmacy service indicators, counselling on how medications work [AOR=9; 95% CI (1.48, 8.85)], keeping to dosage regimen [AOR=7.3; 95% CI (5.49, 11.06)], and advice on the current medical condition had greater odds of client dissatisfaction.

Conclusion

The findings of the current study showed that patients' satisfaction towards outpatient pharmacy services provided by FHCSH is very low as it is indicated in their perception towards revealing written information about medication use, medication availability, medication storage, and instructions about medication side effects.
