Effects of polypharmacy on adverse drug reactions among geriatric outpatients at a tertiary care hospital in Karachi: a prospective cohort study.

Background: Adverse drug reactions (ADRs) present a challenging and expensive public health problem. Polypharmacy is defined according to the WHO criteria as the, ‘‘concurrent use of five or more different prescription medication’’. Elderly are more prone to adverse reactions due to comorbid conditions, longer lists of medications and sensitivity to drug effects. The aim of the study is to estimate the incidence and strength of association of ADRs due to polypharmacy among the geriatric cohort attending outpatient clinics at a tertiary care center. Methods: A hospital based prospective cohort study was conducted at ambulatory care clinics of Aga Khan University Hospital April 2012 to March 2013. One thousand geriatrics patients (age $65 years) visiting ambulatory clinics were identified. They were divided on the basis of exposure (polypharmacy vs. no polypharmacy). We followed them from the time of their enrollment (day zero) to six weeks, checking up on them once a week. Incidence was calculated and Cox Proportional Hazard Model estimates were used. Results: The final analysis was performed on 1000 elderly patients. The occurrence of polypharmacy was 70% and the incidence of ADRs was 10.5% among the study cohort. The majority (30%) of patients were unable to read or write. The use of herbal medicine was reported by 3.2% of the patients and homeopathic by 3%. Our Cox adjusted model shows that polypharmacy was 2.3 times more associated with ADRs, con-current complementary and alternative medicine (CAM) was 7.4 times and those who cannot read and write were 1.5 times more associated with ADRs. Conclusion: The incidence of ADRs due to poly pharmacy is alarmingly high. The factors associated with ADRs are modifiable. Policies are needed to design and strengthen the prescription pattern

Knowledge about osteoporosis among healthy women attending a tertiary care hospital

INTRODUCTION: To determinate the knowledge on osteoporosis-risk factors and disease in three age groups of Pakistani women.METHODS: In this exploratory cross-sectional study, an osteoporosis knowledge assessment questionnaire (OKAT) was used to collect data and it was delivered through a face-to-face interview. Questions were asked about symptoms of osteoporosis, knowledge of risk factors, preventive factors and treatment. A convenience sample (n =320) comprising of three groups of healthy women aged 25-35 years, 36-45 years, and over 45 years was taken. The scoring range was 0 to 20. Among-group comparisions of means were analyzed by two-way ANOVA. To determine the overall influence of osteoporosis-risk factors, the multivariate analysis was used.RESULTS: The knowledge on osteoporosis in younger women was very poor compared to relatively older females. However, women belonging to higher socioeconomic status and better education had slightly more knowledge about osteoporosis compared to those with a low education level, regardless of age.CONCLUSION: The majority of women had modest knowledge on osteoporosis. Younger women were at increased risk for low bone mass and premature osteoporosis

Brain death: concepts and knowledge amongst health professionals in province of Sindh, Pakistan

OBJECTIVE: Last few decades have seen improved resuscitative measures and use of life saving machines like ventilators. Due to these dramatic interventions, end of life decisions, including brain death and organ transplantation, have become more complex and a major problem in our clinical practice. This study was done to find the opinion and awareness of physicians regarding issues surrounding brain death in this region. METHODS: A total of 259 questionnaires were analyzed that encompassed physicians at different level of training and students in the final year of their training, from five major tertiary care centres, located at Karachi and Hyderabad and who are involved in decision making about brain death and related issues. RESULTS: One hundred and forty one (54 percent) respondents did not have a clear idea regarding the definition of brain death. Majority of doctors 122 (47 percent) would therefore not turn off the ventilator even in a brain dead patient. Sixty seven (26 percent) actually considered it Euthanasia. Most considered 24 hrs as optimal period before confirming the diagnosis of brain death. Most of the doctors favoured a confirmatory test, like an electroencephalogram, to confirm the diagnosis of brain death. Majority of the doctors (68 percent) would not consider stopping ventilatory support of a patient in a persistent vegetative state. CONCLUSION: This study highlights the lack of understanding and confusion regarding issues surrounding brain death in this region especially among junior doctors and highlights the importance of including these issues in the medical curricula

Prolonged intermediate syndrome pue to prganophosphate poisoning

Organophosphate poisoning can present as acute cholinergic syndrome, Intermediate syndrome and delayed neuropathy. Intermediate syndrome secondary to organophosphate poisoning is a serious health problem leading to increased morbidity and mortality. The incidence of problem varies and range from 8%-84% of organophosphate poisoning cases. The factors account for this difference is nature of organophosphate compound, severity of poisoning and inadequate Oxime therapy. The recognition of this syndrome is important as organophosphate poisoning is common in our country. We presented this case of organophosphate poisoning leading to prolonged intermediate syndrome. The muscle weakness associated with this syndrome generally resolves in 5-18 days but in our case this lasted for 23 days. After a prolonged Intensive Care Unit (ICU) stay patient was discharged home with no residual symptoms. The case highlights anticipation and recognition of this problem after cholinergic crisis is over

Patients\u27 insight of interpreting prescriptions and drug labels--a cross sectional study.

Background: Errors in consuming drugs are associated with significant morbidity and mortality, besides an impact on the already overburdened health-care system. Misunderstanding drug labels and prescriptions plays an important role in contributing to adverse drug events. Objective: To evaluate abilities to understand prescriptions and drug labels among patients attending tertiary care hospital in Karachi. Methods: A cross sectional study was conducted at the Aga Khan University Hospital (AKUH), from January to March 2009. After informed consent, 181 adult patients and their healthy attendants were interviewed at AKUH using a standardized questionnaire, which ascertained patient demographics, factors that might increase exposure to health-care personnel as well as the basic knowledge and understanding of prescriptions and drug labels. Results: Out of 181, majority 137(76%) had received graduate or post-graduate degrees. 16 (9%) had received no formal education; of which all were females and 89(84%) of the total females were housewives. Overall, 130(72%) followed only a single doctor’s prescription. Majority failed to understand various medical terminologies related to dosage. In the high literacy group, 45(33%) understood once daily OD (p = 0.003), 27(20%) thrice daily TID (p = 0.05), 29(21%) twice daily BD (p = 0.01), 31(23%) thrice daily TDS (p = 0.002) and 43(31%) as needed SOS (p = 0.003) as compared to the group with no formal education, who were unable to comprehend the terms. The most common reason for using more than one prescription was decreased satisfaction with the doctor in 19(39%) and multiple co-morbids as responded by 17(35%) of patients. Knowledge regarding various medical terminologies used for dosage and routes of drug administration were also understood more frequently among the English medium respondents. The elderly identified medicine through color (47%, p,0.001), and were less likely to understand drug indications (p = 0.05) compared to younger subjects. Conclusion: Understanding of drug prescriptions is alarmingly low in the community, even amongst the educated. Care givers need to revisit this often ignored aspect of patient care

Benzodiazepine use in medical out-patient clinics: a study from a developing country

Objective: To estimate the prevalence of Benzodiazepine use in the outpatient setting of general medicine clinics at a single tertiary care centre. Methods: The prospective prevalence study was conducted in the outpatient setting of Internal Medicine Clinics at Aga Khan University Hospital, Karachi, from November to December 2009. All subjects were interviewed after informed consent and variables were recorded on a specially-designed proforma. Apart from basic demographics and comorbid conditions, duration, frequency and route of benzodiazepine use, as well as the reason and who initiated it was noted. Chi-square test and t test was applied to see the association of socio demographic or clinical factors with the use of benzodiazepine. Results: Of the 355 patients, 129 (36.33%) reported using the drug. The majority (n=86; 24.2%) were taking it on a daily basis. The highest numbers of patients using the drug were suffering from cardiovascular problems, 32 (25%) followed by 22 (17%) from endocrinology. Diazepam equivalent dose was around 7.04+4, with a inter-quartile range of 3-96 weeks. Alprazolam (9%) was the most frequently prescribed Benzodiazepine. CONCLUSION: Benzodiazepine use is alarmingly high in the outpatient clinics of General Internal Medicine Department. There is no implementation of law to prevent its hazardous sale. In this regard all concerned should work collectively for awareness and irrational drug sale and use
