OPERATIONAL RESEARCH 1 Moderator-Dr Subhod Gupta Presenter-Dr Rashmi Gode FRAMEWORK Introduction Objective of OR History Features of OR Methodology of OR Approach to carry OR Types of OR study OR examples from India Importance of OR OR and Public Health of India Organisations funding/supporting OR References. 2 INTRODUCTION Terminology-Operational research / Operations research / Management science/Industrial engineering/decision science/problem solving. Single term-OR An interdisciplinary mathematical science that focuses on the effective use of technology by organizations. OR arrives at optimal or near-optimal solutions to complex decision making problems. Science of better 3 WHAT IS OR? Definition- Any research producing practically usable knowledge (evidence, findings, information, etc.) which can improve program implementation (e.g. effectiveness, efficiency, quality, access, scale up, sustainability) regardless of the type of research (design, methodology, approach) falls within the boundaries of operations research” OR uses research techniques to help choose among alternative uses of resources to meet program objectives . 4 OBJECTIVE OF OR To provide the information to program managers and policy decision makers to improve and expand existing services. 5 HISTORY Charles Babbage –(1791-1871) Believed to be father of OR 1940- World war II –team of UK scientists applied scientific techniques to research military operations to win the war and the technique was named as OR World war II- Aim of OR was to discover most efficient usage of limited military resources by application of quantitative techniques. Conclusion of war- defence research in US was increased and OR expanded to other departments. 1951- 1st Book On “Methods of Operations Research” by Morse & kimball India-Operational research society was founded in 1957 6 FEATURES OF OR Decision-making: Every organisation faces multifaceted problems to identify best possible solution to their problems. OR aims to help the executives to obtain optimal solution with the use of OR techniques. Also helps the decision maker to improve his creative and judicious capabilities, analyse and understand the problem situation leading to better control, better co-ordination, better systems and finally better decisions Scientific approach- Scientific methods, techniques and tools for analysis and solution of complex problems. 7 Inter-disciplinary Team Approach : Every problem needs team effort to handle it. It needs Study Between various parameters and evaluate the outcome System Approach.-To trace for each proposal all significant and indirect effects on all sub-system and to evaluate each action in terms of outcome Use of Computers– Possible to handle complex problems requiring large amount of analysis /calculations. 8 WHO IDENTIFIES OR PROBLEMS The patient The programme staff The programme manager The district manager National staff Team approach is needed to identify the problem 9 OR METHODOLOGY Operations Research Problem Analysis Solution Development Solution Validation Evaluation Implementation 10 APPROACH TO CARRY OR Approach Definition Advantage Example Primary level research as factual, first hand accounts of the study written by a person who was part of the study ▪Written by researcher ▪ Original study ▪ Addresses the issues specific to the situation Surveys,(FP) Interviews, Screening, Personal talk, Observations Secondary data analysis as retrospecti ve record reviews defined as an analysis and interpretation of primary research ▪Re-examination ▪Getting information easily in least possible time, ▪Minimum ethical challenges *Switch over from 3 sputum examination to-2 smear in diagnosing Pulmonary TB 11 TYPES OF OR STUDIES Exploratory or diagnostic Field intervention Monitoring and Evaluative Cost effectiveness 12 EXPLORATORY STUDY Help in problem identification Gathers information about interests , attributes ,and need of population. Methods Qualitative ▸Interviews ▸ Observations ▸ Group discussions Quantitative ▸ Cross-sectional ▸ Case control ▸ Cohort studies 13 INTERVENTION STUDY Quasi experimental study Intervention and comparison Pre-post test studies Randomized experiments on effectiveness and efficiency implementation. Highest level of evidence best Choice for Eg: cluster randomised trial In AP –evaluate neonatal mortality reduction 14 MONITORING AND EVALUATION M’ Input , processes and outputs OR E’ Outcome /Impact evaluation Continuous Data collection Implementation Measuring the implementation Eg: RAHI-Rapid appraisal of innovative health interventions under NRHM 15 ECONOMIC ANALYSIS Costing and calculating cost effectiveness Looking for less expensive pathways Eg. Can nurses do the same job as a doctor ? 16 SCOPE OF OR National Planning And Budgeting-Preparation of Five years plans, health services and national health Programmes. Defence services Industrial establishment and Private sector units Research and development and Engineering Business management Agriculture and irrigation Education and training- In Training out the participatory to meet the national project requirements. Transportation 17 OR STUDIES IN INDIA 1) Author--Babu et al. (2008) Study type—Cross sectional Objective--To evaluate reasons for Treatment non-initiation in smear positive pulmonary TB patients diagnosed and reported as initial defaulters (ID) in 20 dist.. Of AP Result-1304 ID, 619 (47.5%) place on Treatment. Out of confirmed (685) ID, 51% were untraceable, 22 % -died before initiation, 5.5% Treated Privately, & 13.5%- had other reasons Program relevance/Policy -Inadequate documentation of referrals, delays in treatment initiation and registration along with deficiencies in address, documentation were highlighted areas for programme improvement 18 2) Authors- Bang & co-workers (1993-2003) Study typeField trial ObjectivesReduction of neonatal mortality in Gadchiroli by Home Based Neonatal care ( HBNC) by capacity building of village level workers ResultsStudy was conducted in 39 interventions and 47 control villages in district Demo significantly declined neonatal, infant and perinatal mortality rates Programme /policy relevance-These study with International evidence on same -2 projects were Initiated ANKUR (2001-05)-In 7 sites in Maharashtra ICMR-5 sites HBNC is adopted in few dist. 19 3) Author- Patel et al.(2003) Study typeEconomic analysis ObjectivesTo ascertain the efficiency of zinc and copper supplementation in the treatment of acute diarrhoea under 5 years. ResultsThe study demonstrated lower cost of treating acute diarrhoea, lower cost per unit health and incremental cost effectiveness ratio Programme / policy relevanceCost savings as evidenced by the study makes a stronger case for micronutrients supplementation as an adjunct therapy to ORS management 20 IMPORTANCE OF OR Global fund believes OR has important role to play in success and strengthening of health program GF support helps to build program’s overall research capacity and ability from data and implementationhelps Eg.1.Systems for delivering antiretroviral treatment (ART) identifying seeking among different population groups, Tanzania 2.Rapid diagnostic test vs. microscopy for malaria in peripheral health facilities , Afghanistan 21 OUTCOME MEASURES OF OR Publications Capacity building of service providers and academic researchers Changes in practice and /or policy 22 OR AND PUBLIC HEALTH INDIA Organises Short term training courses as a part of National Health programmes Short-term training projects Medical colleges also organises research workshops Public health institutions-NIHFW,PHFI WHO-India and USEA initiated TB-OR to develop capacity of professional associated with RNTCP 23 ORGANISATIONS FUNDING/SUPPORTING OR Organisation Bill & Melinda Gates foundation Web Grand challenges explorations website Links www.gatesfoundation.org/default .htm www.gcgh.org/explorations/pages /introduction.aspx Council for the CODESRIA-pioneer development of African social research Social science organization research in africa www.codesria.org/french/default. htm Training Grants and Fellowships www.codesria.org/training_grants .htm Global fund to fight AIDS,TB and Malaria Finances AIDS Tb and Malaria Or proposal must be as part of national disease control proposals www.theglobalfund.org/en/ International development Research centre IDRC-Canada-buil healtheier,equitable and prosperous societies www.idrc.org/en/ev-1-201-1DO_TOPIC.html 24 REFERENCES 1.
