The irrational use of drugs is a major problem of present day medical practice and its consequences include the development of resistance to antibiotics, ineffective treatment, adverse effects and an economic burden on the patient and society. A study from Attock District of Pakistan assessed this problem in the formal allopathic health sector and compared prescribing practices of health care providers in the public and private sector. WHO recommended drug use indicators were used to study prescription practices. Prescriptions were collected from 60 public and 48 private health facilities. The mean (+/- SE) number of drugs per prescription was 4.1 +/- 0.06 for private and 2.7 +/- 0.04 for public providers (p < 0.0001). General practitioners (GPs) who represent the private sector prescribed at least one antibiotic in 62% of prescriptions compared with 54% for public sector providers. Over 48% of GP prescriptions had at least one injectable drug compared with 22.0% by public providers (p < 0.0001). Thirteen percent of GP prescriptions had two or more injections. More than 11% of GP prescriptions had an intravenous infusion compared with 1% for public providers (p < 0.001). GPs prescribed three or more oral drugs in 70% of prescriptions compared with 44% for public providers (p < 0.0001). Prescription practices were analysed for four health problems, acute respiratory infection (ARI), childhood diarrhoea (CD), fever in children and fever in adults. For these disorders, both groups prescribed antibiotics generously, however, GPs prescribed them more frequently in ARI, CD and fever in children (p < 0.01). GPs prescribed steroids more frequently, however, it was significantly higher in ARI cases (p < 0.001). For all the four health problems studied, GPs prescribed injections more frequently than public providers (p < 0.001). In CD cases GPs prescribed oral rehydration salt (ORS) less frequently (33.3%) than public providers (57.7%). GPs prescribed intravenous infusion in 12.3% cases of fever in adults compared with none by public providers (p < 0.001). A combination of non-regulatory and regulatory interventions, directed at providers as well as consumers, would need to be implemented to improve prescription practices of health care providers. Regulation alone would be ineffective unless it is supported by a well-established institutional mechanism which ensures effective implementation. The Federal Ministry of Health and the Provincial Departments of Health have to play a critical role in this respect, while the role of the Pakistan Medical Association in self-regulation of prescription practices can not be overemphasized. Improper prescription practices will not improve without consumer targeted interventions that educate and empower communities regarding the hazards of inappropriate drug use.

The cardiovascular risk profile in this population is consistent with metabolic syndrome where low HDL and WHR can be used to predict the risk of CAD. Results suggest the need to redefine the currently practised approach to CAD management in this population to fit local needs.

In the context of limited effectiveness of iron supplementation programs, intermittent iron supplementation is currently under debate as a possible alternative strategy that may enhance the effectiveness of operational programs. This field-based trial assessed the outcome of twice weekly iron supplementation compared to daily in Pakistan. A double-blind, randomized, clinical trial was conducted in Northern Pakistan. Anemic pregnant women (n = 191) were assigned to receive daily (200 mg ferrous sulfate) or twice weekly (2 x 200 mg ferrous sulfate) iron supplementation. Hemoglobin was measured at baseline and at 4-wk intervals for up to 12 wk. Serum ferritin was measured at baseline and 8 or 12 wk. Analysis was by intention to treat. The two groups did not differ in age, parity, sociodemographic characteristics, hemoglobin or serum ferritin concentrations at baseline. Women who received iron daily had a greater rise in hemoglobin compared with women who received iron twice weekly (17.8 +/- 1.8 vs. 3.8 +/- 1.2 g/L, P < 0.001). The serum ferritin concentrations increased by 17.7 +/- 3.9 microgram/L (P < 0.001) in the daily supplemented group and did not change in the twice weekly group. Daily iron supplementation remained superior to twice weekly supplementation after controlling initial hemoglobin Z-scores and duration of treatment. The body mass index (BMI) modified the effect of daily versus twice weekly iron supplementation. For every unit increase in BMI, the difference between the two treatment groups was reduced by 0.0014 (final hemoglobin Z-score; P = 0.027). We recommend continuation of daily iron supplementation as opposed to intermittent iron supplementation in pregnant women in developing countries.
