BackgroundAdverse 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.MethodsA 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.ResultsThe 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.ConclusionThe 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.
BackgroundErrors 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.ObjectiveTo evaluate abilities to understand prescriptions and drug labels among patients attending tertiary care hospital in Karachi.MethodsA 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.ResultsOut 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.ConclusionUnderstanding 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.
Dedication:This article is dedicated to Professor David Smith, a dear friend and teacher of one of the authors (Claire Turner, CT). CT has known David for 13 years and throughout that time he encouraged, helped and supported CT in developing her interest and breath analysis and VOC analysis. David's attention to detail and uncompromising research ethic has enabled the development of SIFT-MS and without his leadership, the area of VOC and breath analysis would be much diminished. AbstractMonitoring blood glucose concentrations is a necessary but tedious task for people suffering from diabetes. It has been noted that breath in people suffering with diabetes has a different odour and thus it may be possible to use breath analysis to monitor blood glucose concentration. Here, we evaluate the analysis of breath using a portable device containing a single mixed metal oxide sensor during hypoglycaemic glucose clamps and compare that with the use of SIFT-MS described in previously published work on the same set of patients. Outputs from both devices have been correlated with the concentration of blood glucose in 8 volunteers suffering from type 1 diabetes mellitus. The results demonstrate that acetone as measured by SIFT-MS, and the sensor output from the breath sensing device both correlate linearly with blood glucose, however the sensor response and acetone concentrations differ greatly 2 between patients with the same blood glucose. It is therefore unlikely that breath analysis can entirely replace blood glucose testing.Introduction:
IntroductionOur aim was to determine the characteristics of patients presenting with syncope at a tertiary care hospital in Karachi, Pakistan.MethodsA review of medical records was conducted retrospectively at the Department of Medicine, Aga Khan University Hospital, Karachi. Patients aged 16 and above, admitted from January 2000 to December 2005 with the diagnosis of syncope made by the attending physician were included.ResultsA total of 269 patients were included (75% males, mean age: 57.4 years). Neurogenic (vasovagal) syncope was the most common cause (47%), followed by cardiogenic syncope (18%) and orthostatic syncope (9%). A total of 24% were discharged undiagnosed. Twenty patients (7.4%) did not have any prodrome. Common prodromal symptoms included dizziness (61%), sweating (25%), palpitations (19%), nausea/vomiting (19%) and visual symptoms (17%). The distribution of symptoms according to cause of syncope revealed only breathlessness to be significantly associated with cardiogenic syncope (p = 0.002). Most patients with cardiogenic syncope were aged above 40 (98%, p < 0.001), had coronary artery disease (72%, p < 0.001) and abnormal electrocardiogram at presentation (92%, p < 0.001).ConclusionDespite differences in burden of diseases, our findings were similar to those of published syncope literature. Further studies are needed to develop a protocol to expedite the evaluation and limit the work-up and admission in low-risk patients.
Objectives: To assess knowledge and perception among Pakistani physicians towards sepsis. Methods: This cross-sectional study was conducted in Indus Hospital and Health Networks from September 2020 to March 2021. The International Sepsis Survey questionnaire was adapted, and its link was sent to trainee physicians as well as specialists, and consultants practicing in various hospitals via social media. Knowledge and perception were scored and 50% was considered the cut-off score for adequacy. Data was analyzed using SPSS version 26. Results: Analysis was done on 222 respondents who completed the survey. 37.9% of the participants had adequate knowledge. Knowledge regarding sepsis was significantly associated with specialty, ICU/CCU/HDU, and work experience (P-value <0.0001). More recent trainee physicians and those with more experience in critical care areas demonstrated better knowledge. Over 2/3rd of the respondents strongly agreed that sepsis remains one of the unmet needs in critical care today. Conclusion: A common belief exists that sepsis remains a challenge to treat among doctors. Moreover, there is consensus that it is the most frequently miss diagnosed condition in critical care and a dire need exists for its early diagnosis. Additionally, prompt management of presumed sepsis is imperative to improve outcomes. doi: https://doi.org/10.12669/pjms.38.ICON-2022.5775 How to cite this:Ahmed F, Abbasi L, Herekar F, Jiwani A, Patel MJ.

IntroductionHypertension is one of the leading causes of mortality worldwide. Fifty-four percent of strokes and forty-seven percent of cardiovascular deaths are caused by suboptimal control of blood pressure. Economically developing countries like Pakistan are heavily burdened with an ever-rising epidemic of cardiovascular disease and stroke morbidity and mortality. Therefore, urgent steps are required to treat, as well as modify, risk factors for cardiovascular disease, including hypertension.PurposeThe objective of this study was to ascertain the knowledge of hypertension and other sociodemographic variables and their impact on controlling blood pressures in the hypertensive population belonging to the low socioeconomic strata.MethodsThis cross-sectional study was conducted in the general medicine and cardiology outpatient clinics of a tertiary care charity hospital. Three-hundred thirty-five hypertensive patients of age >24 years were selected and informed consent was obtained. Hypertension-related knowledge was assessed using the Modified "Hypertensive Knowledge-Level Scale (HK-LS)" via a 15-20 min interview. Secondary variables in the questionnaire included social demographics, medical history, and assessment of body mass index (BMI) and blood pressure average values, which were measured during the interview. Knowledge was recorded based on the 33-point modified HK-LS scale, whereas secondary variables were not counted toward the assessment of knowledge.ResultsThe frequencies of low, moderate, and high levels of hypertension-related knowledge were recorded as 2.1%, 79.4%, and 62%, respectively. Among 335 patients, (57.3%) were male, the mean age was 52.5 ± 11.5 years, and 63.6% were professionally active. Median systolic blood pressure (SBP) and diastolic blood pressure (DBP) in hypertensive patients were 140 and 86 mmHg, respectively. Sixty-nine percent of patients reported existing comorbidities, 54% had diabetes, 20.7% had cardiovascular disease, and 24% reported renal disease. No significant association was observed between the levels of knowledge of hypertension and gender, blood pressure (BP) status, professional activity, and age groups (p=0.877, p=0.863, p=0.125, and p=0.400, respectively).ConclusionThe majority had adequate knowledge of hypertension but only 64.8% had controlled BP status. This depicts not a lack of knowledge and awareness but rather a lack of prevention of risk factors related to hypertension. Thus, further studies are advised to look into the preventive strategies employed by patients to control their BP and assess their effectiveness.
Introduction Pancytopenia is an important hematologic problem encountered frequently in clinical practice characterized by a reduction in all three peripheral blood cell lineages, i.e., anemia, leucopenia, and thrombocytopenia, caused by myriad disease processes. Our study aimed to determine the frequency and etiology of pancytopenia in patients admitted under internal medicine services in a tertiary care hospital. Method This cross-sectional study was conducted in the in-patient internal medicine department, The Indus Hospital (TIH), Karachi, included 258 patients. To be eligible, participants had to give informed consent, be 14 years or older, and of either sex. The study involved a 20-30-minute interaction with the patient, involving an interview and physical examination, and access to electronic health record data. Results Out of 258 patients studied, 24 (9.3%) were diagnosed with pancytopenia, the male to female ratio was 1:1, no significant difference was observed in the proportion of ethnicity, religion, previous treatment, known infectious disease, and personal and occupational exposure among pancytopenic patients and other nonpancytopenic patients. Fever (n=14, 58.3%) was most common presenting complaint followed by fatigue (n=13, 54.2%) and weight loss (n=7, 29.2%) while most common signs were pallor (87.5% n=21), hepatomegaly (29.2%, n=7), and splenomegaly (25%, n=6). The most common cause of pancytopenia was megaloblastic anemia (n=10, 41.7%), followed by hypersplenism (n=4, 16.6%), acute infectious diseases (n=3, 12.5%), and autoimmune diseases (n=3, 12.5%). Conclusion Our study suggests that pancytopenia is a common finding among our patient population and a larger proportion has a treatable cause, thus carrying a favorable prognosis.
