ICMR programme on Antibiotic Stewardship, Prevention of Infection & Control (ASPIC)

Introduction

Clinical pharmacology, a bridge discipline between basic sciences and clinical disciplines, was started in India in the 1960s1. The development of pharmaceutical industry, clinical trials, accreditation issues in hospitals, and the commitment of the Government to provide essential medicines have necessitated a sea change in the role of the clinical pharmacologist. Capacity building with training in various skills for roles and responsibilities of the clinical pharmacologist is therefore needed. The Indian Council of Medical Research (ICMR) in its centenary year 2011-2012 gave a major boost to development of clinical pharmacology in India and planned workshops in thrust areas2. One of the major thrust areas was that of antibiotic use, resistance and infection control. This area is unique in that it is truly an integrated area covered by the disciplines of clinical pharmacology, microbiology and infectious diseases.

Bacterial infections are a major contributing factor to mortality in the world3, and bacterial resistance to antibiotics has become an all pervading problem throughout the world45, and in India67. One of the major contributing factors towards resistance has been antibiotic use8. Antibiotic use has been seen to be high in India with one recent surveillance study indicating 40 per cent of patients in the community on antibiotics9, and an even higher rate of inappropriate use10. One of the strategies to counter this would be to initiate antibiotic stewardship programmes11. Antibiotic stewardship is a multidisciplinary programme with interventions and strategies to encourage appropriate use of antibiotics. Stewardship programmes aim to restrict inappropriate use of antibiotics, optimize selection, dose, route and duration of treatment for best outcomes, minimizing detrimental adverse events, excessive costs and emergence of resistance. The team involved in Antibiotic Stewardship is multidisciplinary and consists of an infectious disease physician, clinical pharmacologist/pharmacist, clinical microbiologist, infection control nurse and hospital administrator.

These programmes have been shown to have both clinical and economic impact in hospitals12. Strategies such as development and implementation of treatment guidelines, audit and feedback, and parenteral to oral conversion have been shown to be effective. There have however, been barriers also such as lack of awareness and support from physicians, lack of trained manpower and sometimes administrative shortsightedness.

In India, while infection control guidelines and training programme had started relatively early13, Antimicrobial Stewardship programme, guidelines and training have lagged behind. Publications from India on prevention of infection and control are only a few and on antibiotic stewardship are even fewer (Table).

It was, therefore, deemed important by the ICMR that the discipline of clinical pharmacology takes on this void through a training programme not just to build capacity in antibiotic stewardship and infection control and impact hospitals, but also to initiate research projects in different hospital centres which would help in baseline studies and improve the situation with interventional strategies. The ASPIC programme was initiated through the collaboration of the Office of the National Chair of Clinical Pharmacology, ICMR, and the Christian Medical College, Vellore. This report outlines the content of the Antibiotic Stewardship, Prevention of Infection and Control (ASPIC) programme, the primary workshop conducted in 2012 in Vellore, Tamil Nadu, India, the issues in capacity building in Antibiotic Stewardship (AS) and the way forward.

The overall programme was of one year with two contact sessions (workshops) and a project.

ASPIC workshop

The workshop was planned to provide training to participants to equip them with (i) skills and understanding required for infection prevention and control practice; (ii) knowledge and skills required for development and implementation of antimicrobial policy guidelines for rational use of antibiotics to curb antibiotic resistance; and (iii) ability to plan and conduct research projects in antibiotic policy, infection prevention and control practice.

Selection of participants: Twenty participants were selected on the basis of their qualification, past experience and quality of the concept research paper on antimicrobial stewardship and infection control. Among the participants selected, 15 were microbiologists, four were pharmacologists and one was a physician (Figure).

Description of the workshop: The first contact session of five days (April 16-20, 2012) consisted of 40 hours of lectures, site visits, hands on practical training, demonstrations, and project discussion. The main topics covered and types of training assignments given during the workshop were: (i) Patient safety - Lectures, practical demonstration and site visits; (ii) Health care associated infections - Definitions, preventions, demonstration and visits; (iii) Health care workers health and audits in infection control- Lectures and case discussions; (iv) Antimicrobial stewardship- Lectures and case discussions; and (v) Project discussion.

Resource persons for the workshop were faculty from various specialties (Infectious disease, Clinical microbiology, Clinical pharmacology, Nursing, Intensive care, Surgical specialties, and Hospital infection control).

Session outcomes: By the end of the session on patient safety the participants were able to describe the standard precautions to be used to provide patient safety, principles and methods of, hand hygiene, biomedical waste management and its ultimate disposal, and sterilization of instruments.

After the session on health care associated infections (HCAI), the participants were able to describe the definitions, surveillance and prevention of the following HCAI: (i) Catheter related blood stream infection (CR-BSI); (ii) Ventilator associated pneumonia (VAP); (iii) Skin and soft tissue infection (SSI); and (iv) Catheter associated urinary tract infection (CA-UTI).

By the end of the session on health care workers (HCW) health and infection control related audits the participants were able to describe the dos and dont's of needle stick injury prevention, protection of HCW by immunization and post exposure prophylaxis, main steps of outbreak investigation, different audit on various aspects of infection control, and disinfection of various areas and equipment in the hospital.

By the end of the session on the antimicrobial resistance and stewardship the participants were able to describe the following: (i) Surveillance of antimicrobial resistance and antibiotic consumption in their hospital; (ii) Principles of planning standard treatment guidelines and antimicrobial stewardship for their hospitals; and (iii) Principles of epidemiological investigation of antimicrobial resistance in the laboratory.

Project

During the first contact session, research projects to be undertaken at the participant's institution were discussed. Two projects were selected based on the common problems of the centres and the need for improvement. These projects were aimed at assessing the knowledge and practices in two areas in the hospital, viz. use of antimicrobials in surgical prophylaxis, and use of carbapenems/3^rd generation cephalosporins in intensive care units.

After assessment, each centre would develop focused learning modules as an intervention strategy which would be pilot tested and then used as part of the stewardship practice of that hospital. After dissemination of these modules their effectiveness would be assessed by determining the practices once again.

Summary of feedback: All participants found the workshop productive and useful, and they enjoyed the style of teaching, the visits to see various laboratories, processes and facilities. The content of the workshop was felt to be adequate. However, some of the participants were of the opinion that the microbiological aspects could be reduced. The most appreciated session was on antimicrobial stewardship. Many participants wanted more time for project discussion and finalization.

Overall outcomes and evaluation of programme: At the end of the programme, it was hoped that each participant's institution would have a comprehensive systematic Infection Control and Antibiotic Stewardship programme, an Antibiotic Guidelines manual based on the local antimicrobial resistance pattern, and completed research projects and papers for publication.

The programme will be evaluated using the following parameters: (i) Participant attendance for workshops; (ii) Pre- and post-test workshop scores; (iii) Workshop feedback; (iv) Training others in participant's institution and region; (v) Implementation of antibiotic stewardship in participant's institution; (vi) Implementation of infection control practices in participant's institution; (vii) Development of antibiotic policy manual in participant's institution; (viii) Research project initiation and completion; and (ix) Dissemination of findings through publication.

Follow up: The project is expected to be completed within 6-8 months after initiation. The second contact workshop was held in July 2013. The projects were presented, discussed and evaluated. The improvements made in the area of antimicrobial stewardship and infection control in each site hospital were discussed.

Practical issues in the ASPIC programme

The commitment of the participants during the first workshop was commendable. The programme had applications from microbiologists and pharmacologists. The mix of personnel from different disciplines also created the need for a balance of topics between the disciplines in the short span of workshop time.

The participants were from both private and government medical colleges and hospitals. The presence of an infection control team, quality assured microbiology laboratory, and access to various groups of antibiotics, were highly variable across the institutions. This was a challenge when designing projects that would be able to capture the practices and data uniformly from all institutions. The variation in approach of ethics committees in granting permission for projects was time consuming. It was also important to generate projects which were feasible and doable within the short span of time. Planning for collaborative projects when there is a great variation between participating centres, is challenging. Individual institutional projects may be another approach but the comparison as to which is better between both approaches is debatable.

Conclusion

This workshop was the beginning of a programme initiated by the ICMR, National Chair for Clinical Pharmacology and Christian Medical College, Vellore, to train pharmacologists and microbiologists to address the need for Antibiotic Stewardship and Infection Control in various institutions and hospitals throughout India. The focus was to bring together different disciplines and faculty in working towards a common cause, assessing the ground level realities in antibiotic use and hospital infections as well as developing strategic interventions through a collaborative approach to improve infection control and rational antibiotic use. It is hoped that this programme will raise awareness about these issues and empower the participating centres to train other centres so that antimicrobial resistance and hospital infections can be optimally contained.
