Patient Medication Adherence: Measures in Daily Practice

Adherence to therapies is a primary determinant of treatment success. Failure to adherence is a serious problem which not only affects the patient but also the health care system. Medication non adherence in patients leads to substantial worsening of disease, death and increased health care costs. A variety of factors are likely to affect adherence. Barriers to adherence could be addressed as patient, provider and health system factors, with interactions among them. Identifying specific barriers for each patient and adopting suitable techniques to overcome them will be necessary to improve medication adherence. Health care professionals such as physicians, pharmacists and nurses have significant role in their daily practice to improve patient medication adherence.

Acute ingestion of copper sulphate: A review on its clinical manifestations and management

Ingestion of copper sulphate is an uncommon mode of poisoning in the Indian subcontinent. Cases are mainly suicidal in nature. The clinical course of the copper sulphate intoxicated patient is often complex involving intravascular hemolysis, jaundice and renal failure. The treatment is mainly supportive. In severe cases methemoglobinemia needs treatment. Mortality is quite high in severe cases. A comprehensive review of the clinical presentation and management of copper sulphate poisoning is done.

A Study Assessing Public Knowledge, Belief and Behavior of Antibiotic Use in an Omani Population

OBJECTIVE This study was aimed to assess public knowledge, belief and behavior towards antibiotics use in a general population in the Sultanate of Oman. METHODS A 12-item self-administered questionnaire was distributed to 850 prospective participants by researchers using quota sampling in two governorates of Oman. The data obtained were evaluated to assess the responses to individual questions related to knowledge, belief and behavior of antibiotic use. Median score of the respondents was correlated with participant demographics and status on use of antibiotics. RESULTS A total of 718 completed questionnaires were obtained giving a response rate of 85%. The median total score of the participants was 16 (Interquartile range: 6) out of a possible maximum score of 24. A moderate knowledge and behavior score was observed, while the belief score of the participants was low. A significant difference was observed in the median total score based on age group, educational qualification and employment status. CONCLUSION Antibiotics are frequently used by the public. An inappropriate belief on antibiotic related aspects was observed and inappropriate behavior was noticed, which are reflections of insufficient knowledge and wrong beliefs. Interventions must be put in place to educate the public on appropriate antibiotic use.

Drug safety reports on complementary and alternative medicines (ayurvedic and homeopathic medicines) by a spontaneous reporting program in a tertiary care hospital.

OBJECTIVES The objectives of this study were to initiate a pharmacist-coordinated program to improve the adverse drug reaction (ADR) reporting on complementary and alternative medicines (CAM) in a tertiary care hospital and to evaluate the pattern of the reported ADRs. DESIGN A targeted approach was taken in increasing the ADR reporting to CAM in a tertiary care hospital in South India. Suspected ADRs to CAM spontaneously reported over a period of 24 months were selected for evaluation. Reported ADRs were evaluated for patient demographics, reaction and drug characteristics, causality, severity, and outcome. RESULTS A total of 12 ADRs to CAM were reported, which included 9 to Ayurvedic and 3 to homeopathic medicines, which accounted for 1.5% of the ADRs reported to the ADR reporting unit. ADR resulted in hospitalization in 5 patients. The system organ class most commonly involved included skin and appendage disorders (58.3%). Only four of the reactions were previously reported in the literature. The mean time for onset of the ADR after the administration of the drug was 27.8 +/- 36.1 days. The suspected drug was withdrawn in all the reports that resulted in recovery, with mean time for recovery 5.9 +/- 3.6 days. The majority (66.6%) were moderate in severity and 2 were severe in nature. On causality assessment, 6 were probable in nature and the remaining were possible. CONCLUSIONS Even though there were fewer ADRs reported by this spontaneous reporting system, it gave valuable information regarding the potential for adverse effects with these agents. The study has reinstated the potential role of spontaneous reporting in identifying lesser reported ADRs, including those to CAM. Such hospital-based programs can contribute much in increasing the safety-related data of these agents.

Adverse drug reactions to fluoroquinolone antibiotics - Analysis of reports received in a tertiary care hospital

Fluoroquinolones are one among the most commonly prescribed antibiotics in hospital set up. Only few published studies are available which tried to characterize the nature of ADRs to fluoroquinolones encountered in a hospital set up. The present study was aimed at analyzing the pattern of ADRs implicated to fluoroquinolone antibiotics reported spontaneously to the ADR reporting unit of a tertiary care teaching hospital in India. ADRs reported over a period of 4 years and 6 months were analyzed. Evaluation was done for patient demographics, drug and reaction characteristics, predisposing factors, and outcome of reactions. Analysis for causality, severity and preventability was also done. Eighty ADRs associated with fluoroquinolones were notified during the evaluation period, which accounted for 5.4% of the total ADRs reported in the ADR reporting unit and 30.2% of all reports to antibacterials. Type A reactions (58.8%) accounted for majority and more were described to be common (48.8%) in the literature. Levofloxacin (48.8%) occupied the major share of the reactions reported. Pattern of ADRs observed was comparable to that reported in literature. The organ system most commonly affected was skin and appendages (32.5%) and the most frequently reported reaction was skin rash (21.3%). Interestingly, no report of reactions affecting musculoskeletal system was observed while rare reaction like nephrotoxicity was noticed. The proportion of nervous system adverse reactions noticed were higher than that observed with antibacterial agents in general. Drug dechallenge was instituted in majority (73.8%) for management of the reactions, while additional treatment was instituted in 50% of the reactions. More of the reactions were probable (52.5%) in nature on causality assessment and were of moderate (72.5%) severity. Many (23.8%) of the reactions were deemed to be preventable on evaluation. Drug-drug and drug-disease interaction were the most important factors which contributed to preventability. Even though ADRs to fluoroquinolones are considered mainly to be mild in severity, our eval- uation revealed considerable number of reactions of moderate severity. The present evaluation has revealed opportunities for interventions especially for the preventable ADRs which will help in promoting safer use of this important group of antibiotics. Cautious use of these agents especially in patients with predisposing factors and proper monitoring is warranted. Spontaneous reporting programs in spite of its limitations are useful in identifying pattern of ADRs in a hospital set up. Similar hospital based evaluation will provide valuable information which would help in promoting safe use of these medications.

Statin associated hepatic adverse effects: a retrospective review from a regional hospital in sultanate of oman.

OBJECTIVE This study aimed at evaluating the prevalence, pattern and predisposing factors for hepatic adverse effects with statins in a regional hospital in Sultanate of Oman. METHODS A retrospective review of the patient files in Department of Medicine during the year 2011 was done to evaluate any hepatic dysfunction possibly related to statins among the patients. For each case of suspected statin induced hepatic effect, additional details on temporal relationship, pattern of presentation, management, final outcome and any contributing factors were obtained. Difference in the occurrence of hepatic effects based on the patient demographics and drug characteristics was additionally evaluated. RESULTS A total of 927 patients meeting the inclusion criteria were included for the study. Mean age of the evaluated patients was 63.1 ± 11.37 and median duration of use of statin in months was 22 (IQR, 43.25). In 40 (4%) of the 927 patients, there was presence of a hepatic effect considered to be statin related and only in 12 (1%) patients a significant transaminase rise (>3 times) was observed. Median duration of use of statin among those patients who developed suspected statin induced hepatic effects and those who did not was 45 (IQR,52) and 21 (IQR, 43) months, respectively and the difference observed was statistically significant. A significant difference in the prevalence of hepatic effects was observed only based on the duration of statin use. CONCLUSION There was an infrequent occurrence of significant hepatic effects associated with statins in the study population. Our results support the latest recommendations including from United States Federal Drug Administration (US FDA) that statins appear to be associated with a very low risk of serious liver injury and that routine periodic monitoring of transaminases does not appear to detect or prevent serious liver injury in association with statins.

Distal sensory polyneuropathy in human immunodeficiency virus patients and nucleoside analogue antiretroviral agents

Distal sensory polyneuropathy, which occur commonly in human immunodeficiency virus (HIV) patients can occur as a consequence of the disease itself or the antiretroviral treatment the patient is receiving. Among the antiretroviral agents, nucleoside analogues are commonly associated with neuropathy and the main underlying mechanism is thought to be the mitochondrial toxicity exhibited by these agents. Clinical presentation of antiretroviral induced neuropathy is similar to that associated with the HIV infection and in many patients they may overlap. Treatment is primarily symptomatic and certain pathogenesis-based approaches have shown promising results.
