Clinical pattern and drug-related problems among colorectal cancer patients at oncology center in Ethiopia: A hospital-based study

An assessment of the prevalence of drug therapy problems and its associated factors among ovarian cancer patients at Kenyatta National Hospital

IntroductionDespite several studies in various cancers reporting a high prevalence of drug therapy problems (DTPs), there is a notable scarcity of comprehensive data addressing DTPs among patients with an ovarian cancer diagnosis. This study aimed to assess DTPs among those patients at Kenyatta National Hospital.MethodsA retrospective cohort study was used to assess the prevalence of DTPs among all 100 eligible patients with an ovarian cancer diagnosis. This research used a data abstraction tool to gather ovarian patients' data on drug therapy problems. The statistical package for Social Science version 20.0 software was used for data entry and analysis. The findings were presented using frequency tables, percentages and figures.ResultsThe mean age of the study population was 51.2 ± 15.1 with a bigger population being above 50 years (57.0%). The prevalent histological type of ovarian cancer was epithelial ovarian cancer (79.0%) followed by sex cord-stromal ovarian cancer (13%) and germ cell ovarian cancer (8%) which was least prevalent. A total of 175 DTPs were identified with the most prevalent being adverse drug reactions (40.6%) and drug non-adherence (17.1%). The number of medications used and stage of ovarian cancer as statistically significant predictors of DTP.ConclusionThe prevalence of DTPs was high and the most prevalent DTP was adverse drug reactions. The number of medications used and the stage of ovarian cancer were statistically significant predictors of DTP. Hence, regular medication reviews and robust pharmacovigilance systems should be implemented to detect and manage DTPs effectively.

Medication Management of Patients With Cancer Undergoing Surgery From Preadmission to Discharge: A Mixed-Methods Systematic Review

AIM(S)

To identify and synthesise available evidence about regular medication management processes, from preadmission to discharge from hospital, in patients with cancer undergoing surgery.

DESIGN

Mixed-methods systematic review.

METHODS

Studies published from inception of each database until February 2023 were screened, utilising four main search concepts. The JBI methodology for mixed-methods systematic review was followed in this review.

DATA SOURCES

MEDLINE, CINAHL, EMBASE, APA PsycINFO, Scopus and Web of Science.

RESULTS

Eight out of 717 screened studies were included. Two themes related to patients' medication management were identified. Preoperative factors such as polypharmacy, potentially inappropriate medications, delirium-inducing medications and preoperative discontinuation-requiring medications were associated with several postoperative complications in patients with cancer. Additionally, pharmacist-led interventions and collaborative efforts between nurses and patients were shown to improve the medication management process across the perioperative pathway.

CONCLUSION

This systematic review emphasises the necessity of effectively managing regular medication, especially before surgery, to mitigate postoperative complications in patients with cancer. It offers critical insights into how involving pharmacists and nurses enhances medication management outcomes, benefiting health care professionals and institutions aiming to optimise perioperative medication therapy.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Enhancing patients' regular medication management through comprehensive reviews before surgery, and improving collaborative practices among pharmacists, nurses and patients via targeted interventions introduced by health care organisations, ensure safe medication use throughout the perioperative pathway.

IMPACT

Improving regular medication management process can reduce risk of medication errors and adverse drug events and enhance postoperative outcomes.

Incidence and determinants of mortality among patients with colorectal cancer in oncology centers of Amhara region, Ethiopia, 2024: multicenter retrospective follow up study

INTRODUCTION

Colorectal cancer is a significant cause of mortality globally, with several factors impacting patient outcomes, including access to healthcare, early detection, and treatment. Despite this, the specific factors affecting incidence of death among colorectal cancer patients in the Amhara region have not been thoroughly investigated. Thus, this study seeks to assess incidence and determinants of mortality among colorectal cancer patients in Amhara Region oncology centers.

RESULTS

The mean age of the participants was 48.6 years (SD ± 15). Median survival time was 23.8 months. The overall incidence rate or incidence density of a colorectal cancer mortality rate was 2.9 per 100 person-months (95% CI: 2.5-3.4). Survival rates of colorectal cancer patients 1and 5 year was 69.78% and 16.1%, respectively. The result of the multivariable analysis showed that colorectal cancer patients who had presenting symptoms [AHR = 2.67 (95% CI: 1.95, 3.67)], Base line HGB level < 12.5 mg/dl [AHR = 1.63 (95% CI: 1.12, 2.37)], WHO or ECOG poor performance status [AHR = 2.99 (95% CI: 2.17, 4.12), late stage of cancer [AHR = 2.32 (95% CI: 1.42, 3.79)] and location of tumor on colorectal [AHR = 1.76 (95% CI: 1.20, 2.55)] were significantly associated with mortality of colorectal cancer.

CONCLUSION AND RECOMMENDATION

The study highlights significant findings on the survival and mortality of colorectal cancer patients. The overall mortality rate was 2.9 per 100 person-months. Multivariable analysis identified presenting symptoms, low baseline hemoglobin levels, poor performance status, late-stage cancer, and tumor location as significant predictors of mortality. Highlighting the need for early detection and targeted care strategies.

Magnitude of cancer-associated thrombosis in Africa: A systematic review and meta-analysis

Comprehensive data on the epidemiology of cancer-related thrombosis in Africa has been sparse until recently. Thus, this review was aimed to investigate the magnitude of cancer-related thrombosis in Africa. To obtain key articles, comprehensive search was conducted using various databases. A random-effects model was used to determine the pooled magnitude. Heterogeneity across the studies was checked, and publication bias was determined. The pooled magnitude of thrombosis among cancer patients in Africa is 11.65% (95% confidence interval [CI]: 9.02-14.28). Advanced age, comorbidity, and level of D-dimer were the factors associated with cancer-associated thrombosis. Cancer-related thrombosis has become a significant public health burden in Africa. About 3 out of 25 cancer patients are at increased risk of acquiring thrombosis. It is better to provide training and capacity-building programs for healthcare providers in Africa on the prevention, diagnosis, and management of cancer-related thrombosis and develop standardized evidence-based multidisciplinary approach care guidelines.

Managing drug therapy-related problems and assessment of chronic diabetic wounds

Type 2 diabetes mellitus (T2DM), responsible for most diabetes cases recorded worldwide, increases the risk of chronic wounds and amputation. Patients with T2DM appear to be more susceptible to delayed wound healing due to their treatment adherence. This review explores the specifics of polypharmacy, side effects, possible drug interactions and the importance of medication adherence for therapeutic efficacy. We discuss the effects of anti-diabetes medications on wound healing as well as the role that biofilms and microbial infections play in diabetic wounds. Inconsistent use of medications can lead to poor glycaemic control, which negatively affects the healing process of diabetic foot ulcers. Managing chronic wounds represents a substantial portion of healthcare expenditures. Biofilm-associated infections are difficult for the immune system to treat and respond inconsistently to antibiotics as these infections are slow growing and persistent. Additionally, we emphasize the critical role pharmacists play in enhancing patient adherence and optimizing diabetes treatment by offering comprehensive coverage of drugs associated with problems related to pharmacological therapy in type 2 diabetes.

Drug therapy problems among paediatric acute lymphoblastic leukaemia patients at Kenyatta National Hospital

INTRODUCTION

Several studies reported that drug therapy problems (DTPs) were prevalent in cancer patients. These DTPs are still interfering with the desired treatment outcomes in patients with cancer. This study aimed to determine the prevalence, types and predictors of DTPs among paediatric acute lymphoblastic leukaemia (ALL) patients at Kenyatta National Hospital.

METHODS

A retrospective cohort study was used to assess DTPs among ALL patients. Records of all eligible paediatric patients with ALL who received treatment in the facility between 1 January 2017 and 31 December 2021 were examined. A data abstraction tool was employed for data collection. The data entry and analysis were carried out by a statistical package for social sciences version 29.0 software. Frequency tables were utilised to present the key findings of the study. Binary logistic regression analysis was utilised to determine the predictors of DTPs.

RESULTS

A total of 82 DTPs were identified with the most common type of DTP being adverse drug reaction (ADR; 59, 72.0%) and drug interaction (9, 11.0%). The most common ADRs identified were febrile neutropenia (20, 33.9%), nausea/vomiting (14, 23.7%) and anaemia (11, 18.6%). Patients with central nervous system disease (adjusted odds ratio [AOR] = 10.2, 95% CI = 1.2-85.8, p = 0.03) and treated with a combination of chemotherapy and radiotherapy (AOR = 13.5, 95% CI = 1.9-89.4, p = 0.01) were more likely to develop DTPs.

CONCLUSION

The study found that the prevalence of DTPs among paediatric ALL patients was high, with the most common DTPs being ADRs occurring in 72.0% of patients. Central nervous system metastasis and a combination of chemotherapy and radiation treatment regimens were statistically significant predictors of DTPs.

Drug-related problems among esophageal, gastric and colorectal cancer patients at the National and referral hospital in Kenya

INTRODUCTION

Cancer therapy has remarkable potential for drug-related problems due to the high cytotoxicity and narrow therapeutic index of most anti-neoplastic regimens. However, there is a lack of comprehensive studies on drug-related problems in patients with gastrointestinal cancer in Kenya. Therefore, the present study aimed to investigate the prevalence, types and predictors of drug-related problems among gastrointestinal cancer patients at Kenyatta National Hospital.

METHODS

A cross-sectional study was used to assess the prevalence of drug-related problems among a random sample of 160 esophageal, 103 gastric, and 96 colorectal cancer patients. Data were collected using a researcher-administered questionnaire and data abstraction tool after training the data collectors. Patient-specific details such as socio-demographic features, histological cancer types, cancer stage, comorbidity types, and treatment regimen were recorded after the review of medical records and patient interviews. The potential of drug-related problems was determined as per the standard guidelines. The data were entered and analysed using version 26.0 SPSS statistical software.

RESULTS

Most esophageal (51.9%), gastric (59.2%), and colorectal (62.5%) cancer patients had a high prevalence of drug-related problems. The need for additional drug therapy and adverse drug reactions were the predominant categories of drug-related problems. Most adverse drug reactions identified had possible categories of causality score, mild severity levels, and definitely preventable types of adverse drug reactions among all gastrointestinal cancer patients. Comorbidity and advanced-stage disease were significant predictors of drug-related problems.

CONCLUSIONS

Drug-related problems were prevalent among gastrointestinal cancer patients in our setting. Comorbidity and advanced stages of disease were significant predictors of drug-related problems.

Drug-related problems in cancer patients: A systematic review

BACKGROUND

Cancer patients are at a significantly increased risk of drug-related problems due to multiple drugs. An inclusive review of drug-related problems would offer an approach for healthcare providers to decrease the frequency of drug-related problems in cancer patients. The purpose of this study was to assess all characteristic components of drug-related problems in cancer patients, and explore actions taken to resolve the detected drug-related problems the results could be used as a baseline for epidemiology and potential related risk factors for drug-related problems in cancer patients.

METHODS

The present systematic review was done according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search consisted of studies listed from January 2015 and up to May 2023. A systematic review was carried out using an electronic database with a combination of Medical subject Headings of key words Medical Subject Heading terms.

RESULTS

This evaluation included 17 studies from 11 different nations having 11 prospective and 6 retrospective studies. Pharmaceutical Care Network Europe classification system is the most commonly used to classify the drug-related problems. The prevalence of drug-related problems varied from 9.6% to 92.8%. The key predictors of the drug-related problems were age, polypharmacy, multiple comorbidities, and the stage of the disease.

CONCLUSION

Drug-related problems are significantly more common among cancer patients. The age, polypharmacy, multiple comorbidities, and the stage of the malignancy all enhance the risk of acquiring drug-related problems. This review raises awareness of drug-related problems, encourages their early detection, and emphasizes the necessity for framing effective drug-related problem management strategies which will enhance patient care.

Management pattern and medication-related harms and its predictors in colorectal cancer patients: an institutional-based retrospective study

Introduction

Data on colorectal cancer (CRC) patients' thorough management practices and medication-related harms (MRH) are scarce. This study's aim was to investigate the MRHs in patients receiving CRC chemotherapy at the comprehensive specialized hospital of the University of Gondar (UoGCSH).

Methods

A registry-based retrospective cohort study was conducted on CRC patients at the UoGCSH during 2017-2021. From February to May 2022, medical records were reviewed using a pretested data collection tool to collect socio-demographic and disease-related characteristics, MRHs, and medication regimens. MRHs occurrence and adverse drug reactions (ADRs) severity were assessed using standard guidelines and protocols. Version 16/MP of STATA for Windows was used for the analysis. Independent predictors of MRHs were investigated using logistic regression analysis. A p-value ≤0.05 was used to determine an independent variable's statistical significance.

Results

One hundred forty three CRC patients were included, with a mean age of 49.9 ± 14.5 years. About 32.9% and 33.6% had stage II and III cancer, respectively. Significant patients had co-morbidities (15.4%) and complications (13.3%). Fluorouracil (5-FU)-based regimens were given to more than half (56%) of the patients. MRHs were found in 53.1% of the patients, with a mean of 2.45 ± 1.37 MRHs. The most common MRHs were the need for additional drug therapy, sub-therapeutic dose, DDIs, and ADRs. Being on stage IV (AOR = 27.7, 95% CI = 3.85-199.38, p = 0.001), having co-morbidity (AOR = 7.42, 95% CI = 1.80-30.59, p = 0.018) and having complication (AOR = 11.04, 95% CI = 1.72-70.95, p = 0.011) and treated with five or more drugs (AOR = 2.54, 95% CI = 1.07-6.07, p = 0.035) were independent predictors of MRHs.

Conclusion

A fluorouracil-based treatment regimen was most frequently used. MRHs were found in nearly half of CRC patients. Furthermore, MRHs were significantly associated with cancer stage, comorbidity and complication status, and the number of medications used. Because MRHs are common, improving clinical pharmacy services is critical for optimizing drug therapy in CRC patients.
