Patients' 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.

APACHE II scores as predictors of cardio pulmonary resuscitation outcome: Evidence from a tertiary care institute in a low-income country.

AIM: The aim of this study was to demonstrate that APACHE II scores can be used as a predictor of the cardio-pulmonary resuscitation (CPR) outcome in hospitalized patients. METHODS: A retrospective chart review of patients admitted, from 2002 to 2007, at the Aga Khan University Hospital, Karachi, was done for this study. Information was collected on 738 patients, constituting all adults admitted in general ward, ICU, CICU and SCU during this time, and who had under-went cardiac arrest and received cardiopulmonary resuscitation during their stay at the hospital. Patient characteristics, intra-arrest variables such as event-witnessed, initial cardiac rhythm, pre arrest need for intubation and vasoactive drugs, duration of CPR and survival details were extracted from patient records. The APACHE II score was calculated for each patient and a descriptive analysis was done for demographic and clinical features. The primary outcome of successful CPR was categorized as survival >24 h after CPR versus survival <24 h after CPR. Multivariable logistic regression was used to assess the association between the explanatory variables and successful CPR. RESULTS: Patients with APACHE II scores less than 20 had 4.6 times higher odds of survival compared to patients with a score of >35 (AOR: 4.6, 95% CI: 2.4-9.0). Also, shorter duration of CPR (AOR: 2.9, 95% CI: 1.9-4.4), evening shift (AOR: 2.1, 95% CI: 1.3-3.5) and Male patients (AOR: 0.6, 95% CI: (0.4-0.9) compared to females were other significant predictors of CPR outcome. CONCLUSION: APACHE II score, along with other patient characteristics, should be considered in clinical decisions related to CPR administration.

Drug overdose: a wake up call! Experience at a tertiary care centre in Karachi, Pakistan.

OBJECTIVE: To study the characteristics of patients admitted with drug overdose caused either by accidental overdose of the prescribed medications or as an act of deliberate self harm (DSH) at a tertiary care hospital in Karachi, Pakistan. METHODS: A retrospective case series review was conducted at the Aga Khan University Hospital from January 2002 to October 2006. Three hundred and twenty four adult patients admitted with drug overdose were included in the study. RESULTS: Our sample group revealed mean age of 36.2 +/- 17.0 years, more females (59%), housewives (34%), and students (20%). Fifty six percent of patients committing DSH were married (p = 0.001), 81% needed in-patient psychiatric services (p = 0.016) of whom a significantly high number (38%) refused it. Domestic and social issues were rated highest among DSH group (p = 0.003), depression among females was common (p = 0.028) and Benzodiazepines (41%) was the most frequently used drug (p = 0.021). Sub-group analysis of accidental overdoses revealed mean age of 45.6 +/- 19.6 years, single (75.4%) and males (54.1%). Drugs used were mainly Benzodiazepines (18%) followed by Opioids (11%), Antiepileptics (10%) and Warfarin (10%). CONCLUSION: Our study showed that depressed housewives are at greater risk for DSH. Domestic and social issues were rated highest and Benzodiazepines were the most commonly used agents. Most of our patients refused inpatient psychiatric treatment leading us to believe that general awareness of psychiatric illnesses is imperative in our community. High number of accidental overdoses is alarming in older, single males convincing us to believe that existing pharmacy system needs further evaluation and modification.
