Antibiotic stewardship initiative in a Medicine unit of a tertiary care teaching hospital in India: A pilot study

Background & objectives: The models for implementation of antibiotic stewardship programme (ASP) in the acute care settings of developing countries are lacking. In most of the hospitals, patient turnover is high and a proper system for recording antibiotic-related information and tracking hospital-acquired infections is not in place. This pilot study was conducted in a tertiary care teaching hospital in north India to assess the feasibility of implementation of an ASP in a Medicine unit and to evaluate the effect of implementation as per the criteria applicable in this set up. Methods: A pre-post-quasi-experimental non-randomized study was conducted in two phases. In the first phase, current practices in the Medicine wards were observed. In the second phase, the ASP was implemented in a single Medicine unit, along with prospective audit and feedback, tracking of the process, as well as outcome measures. Patient risk stratification, blood culture on day one, day 3 bundle, dose optimization, de-escalation and intravenous to oral conversion of antibiotics were the key elements focused upon. Results: There was a significant improvement in the appropriateness of antibiotic prescription (66 vs. 86%, P<0.001) and reduction in the mean number of antibiotics used per person (4.41 vs. 3.86, P<0.05) along with decrease in the duration of hospital stay (17 vs. 14 days, P<0.05). There was a significant improvement in sending of blood cultures on day one during the stewardship phase (P<0.001). Interpretation & conclusions: The ASP approach used in our pilot study may be feasible and beneficial. However, it needs further confirmation in other settings and on a large scale.

Mortality due to scrub typhus � report of five cases

Scrub typhus is largely ignored in India particularly during outbreaks of viral fever. The disease course is often complicated leading to fatalities in the absence of treatment. However, if diagnosed early and a specific treatment is initiated, the cure rate is high. We report here five cases of scrub typhus to highlight the fact that high clinical suspicion for such a deadly disease is an absolute necessity.

Is there need for a transformational change to overcome the current problems with postgraduate medical education in India.

In spite of the existence of a dual system of postgraduation, one under the Medical Council of India (MCI) and the other on a parallel track under the National Board of Examinations, postgraduate medical education in India is beset with several problems. For example, the curriculum has not been revised comprehensively for several decades. The diploma course under the MCI has become unpopular and is largely a temporary refuge for those who do not get admission to degree courses. The level of skills of the outgoing graduate is falling and the increase in the number of seats is taking place in a haphazard manner, without reference to the needs. In spite of increase in seats, there is a shortage of specialists at the secondary and tertiary care levels, especially in medical colleges, to share teaching responsibilities. Further, the distribution of specialists is skewed, with some states having far more than others. To remedy these ills and fulfil the requirements of the country over the next two decades, a working group appointed by the erstwhile governors of the MCI was asked to suggest suitable modifications to the existing postgraduate system. After an extensive review of the lacunae in the present system, the needs at various levels and the pattern of postgraduate education in other countries, it was felt that a competency-based model of a 2-year postgraduate course across all specialties, the use of offsite facilities for training and a criterion-based evaluation system entailing continuous monitoring would go a long way to correct some of the deficiencies of the existing system. The details of the proposal and its merits are outlined for wider discussion and to serve as a feedback to the regulatory agencies engaged in the task of improving the medical education system in India. We feel that the adoption of the proposed system would go a long way in improving career options, increasing the availability of teachers and dissemination of specialists to the secondary and primary levels, and improving the quality of outgoing postgraduates.

A new focus of visceral leishmaniasis in sub-Himalayan (Kumaon) region of northern India.

A localised focus of visceral leishmaniasis is reported for the first time from Kumaon region of North India. During a period of 18 months from July 1997 to December 1998 several cases of pyrexia of unknown origin with unresponsiveness to antibiotics and anti-tubercular treatments were referred to the All India Institute of Medical Sciences, New Delhi. Five of these were diagnosed to have visceral leishmaniasis. One of these was also co-infected with HIV-1. All the five cases came from an adjoining area falling under Almora (4) and Nainital(1) districts. Of these four were males and one female. One patient died within 48 hours of hospitalization at AIIMS while rest of four responded completely to sodium stibogluconate therapy.

Awareness of hypertension among a north Indian population.

Developing countries are going through a demographic transition. Non-communicable diseases like hypertension are emerging in epidemic proportions. Education and awareness among people is the key to reduce the burden of the disease. To see the levels of awareness and characteristic of aware and unaware hypertensives, 7630 employees in Shimla town were screened for hypertension. Hypertension was detected in 2535 cases of which 559 (22.05%) were aware. The aware hypertensives were predominantly symptomatic and had higher age and blood pressure than the unaware hypertensives. The aware hypertensives were predominantly overweight. This low level of awareness highlights the need for a comprehensive hypertension education programme to be taken up at the national level.

Multiple organ dysfunction syndrome.

The simultaneous dysfunction of several organs represents a challenging task for the intensivist. Systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) are expressions of an inappropriate generalized inflammatory response of the host to a variety of infectious or non-infectious stimuli. In recent years, MODS is being encountered frequently in critically ill patients due to several causes. Experimental and clinical evidence suggests that the gut, endothelium and immune system interact to produce altered metabolic and cardiorespiratory patterns. It is thus possible that a target-oriented approach, including correction of intestinal hypoperfusion, supply of specific nutrients and downregulation of the inflammatory cascade, can act as either a preventive measure for subjects as risk or as the treatment for patients with full-blown MODS.

Immunization coverage among urban and rural children in the Shimla hills.

A cross sectional study was carried out to assess immunisation coverage among 257 urban and 339 rural children aged 13-36 months who were vaccinated at pulse polio booths in Shimla hills. 84.37% urban children and 57.59% rural children were fully vaccinated. BCG scar was negative in a large number of children, especially from rural areas. Increasing maternal education was associated with complete immunisation. OPV I-III dropouts were 3% among urban children and 15% among rural. The corresponding dropout rates for DPT I-III were 1% and 8% respectively. The immunisation coverage in this region was higher than others. Sustained efforts are required to achieve full immunisation coverage and eradicate polio and measles.

Age during breast feeding and timely suckling.

A cross sectional study of 398 mothers and infants was conducted to assess the age at first breast feeding, and its determinants, in Shimla. We found that the timely first suckling rate was 0.10 in urban group and 0.11 in rural group. The median age at initiation of breast feeding was five hours among urban cases and four hours among rural cases. Most of the infants were breast fed by the age of 24 hours which is a positive sign and is higher than previous studies. Absence of definite trend vs mother's education may be due to other factors. A community-based educational programme to promote early breast feeding is required, along with training on lactation management counselling for health workers. This will help in achieving healthy child development through prevention of childhood malnutrition.

An epidemiological study of obesity in Shimla Town.

A cross sectional study of 888 randomly selected subjects in Shimla town was done to determine prevalence of obesity, its relation to age and physical activity. The prevalence of obesity was 21.5% using cut off levels of BMI 25. The prevalence of obesity rose significantly with age. Obesity was less in those having moderate physical activity as compared to those with low and high activity. Primary prevention is required to tackle this disease risk factor through health education focussing on promotion of moderate regular physical activity.

Metastatic carcinoma involving the testes.

Metastatic carcinoma to testis is an extremely rare but interesting phenomenon. Over a period of nineteen years 300 testicular tumors were diagnosed in our department, and of which 10 were metastatic carcinoma from other sites. Four of these patients (40%) presented as testicular lump of which two were already diagnosed cases of squamous cell carcinoma larynx and adenocarcinoma of lung, and two had occult primary in the kidney and colon. However six (60%) were detected incidentally in the orchiectomy done as a part of hormonal therapy for carcinoma prostate.
