Lecture 03: Defining your research questions SoHP503 Project studies Dr Daniela Oehring S4 Code of the day ADD CODE Agenda What are we going to do? Intended learning outcomes Using evidence to make Explain what PICO is & what the decisions and to answer letters stand for practical/clinical/ research Apply PICO framework to a specific questions topic or scenario Formulate an answerable clinical Formulating searchable question using PICOTE questions Identify the components of a successful research question. Create a viable research question. Finding evidence Project Studies | SoHP503 | Dr Daniela Oehring 2 Virtual Meeting Etiquette SoHP503 Turn off your phone Leave the keyboard alone (unless you are typing something in the chat, or you are doing an activity) Dress appropriately (Don’t wear your pyjamas, have a shower before the session starts and something to eat and drink) Be aware of your surroundings (No beds, No messy rooms, No inappropriate posters/ backgrounds) Mute your microphone when you’re not talking Speak up Stay seated and stay present (Position your camera so that your whole head is visible and not just your forehead, chest or the room) Project Studies | SoHP503 | Dr Daniela Oehring 3 Any questions Project Studies | SoHP503 | Dr Daniela Oehring 4 Anatomy of the research process SoHP503: Journey from choosing a topic to developing the research project proposal SoHP603: Journey from collecting the data to communicating your findings (via your dissertation) Project Studies | SoHP503 | Dr Daniela Oehring 5 Using evidence to make decisions and to answer practical/clinical/ research questions SoHP503 Project studies Dr Daniela Oehring Decision making process According to Hastie and Dawes (2010) the process to make a decision is built of three parts: 1.There has to be more than one possible course of action 2.The decision maker considers the possible or excepted outcomes 3.The consequences are assessed of each possible outcome based on personal beliefs and goals Project Studies | SoHP503 | Dr Daniela Oehring 10 Use of evidence to decide Thomson & Stapley (2011) characterised the different types of decision in clinical practice: Decisions about intervention Decisions about which patients will benefit most from an intervention Decisions about the best time to intervene Decisions about when to deliver information Decisions about how to manage a service or care delivery Decisions about how to reassure patients Project Studies | SoHP503 | Dr Daniela Oehring 11 Consequences and implications of decisions Some decisions will be more important than others. This depends on the nature of risk or potential for harm involved for the patient and the costs. In clinical practice: Can you identify areas with higher risk? Are the interventions commonly used in this areas based on EBP? What if there is no research evidence available? Project Studies | SoHP503 | Dr Daniela Oehring 12 Types of evidence Statistical General practice: you should adopt the most appropriate Evidence care and be able to justify it with reference to the most appropriate evidence. Testimonial Evidence Types: Primary research or review of research Anecdotal Policy, guidelines, care pathways Evidence Clinical or professional judgement Patient experience, reflective judgment, Analogical expertise of others Evidence Project Studies | SoHP503 | Dr Daniela Oehring 13 Types of evidence Statistical evidence: research Anecdotal evidence: You would use this to prove a point Something you tried before that worked (without checking evidence to support it) Testimonial evidence: eye- From colleagues or supervisors: “We’ve always done it like this” whiteness, correspondence From discussion papers, opinion articles You would use this to support a point or editorials Expert opinions You would use this to support a point or to disprove a generalisation Analogical evidence Avoid this Project Studies | SoHP503 | Dr Daniela Oehring 14 Examples - Which evidence do you need to help you make a decision? My hospital patient has been diagnosed as an alcoholic and shows first signs of vision loss regards to alcohol overuse but wants self-discharge against the judgment of staff. What should I do? You work with a student colleague on a placement. Your colleague has considerable personal issues and don’t appear to be coping well. How should you handle it? My patient has asked me about a particular vision therapy to improve …(visual) performance of their child. What should I advise? I want to know if it is better to use specific optotypes/ exercise/ occupation/ treatment in assessing diabetic patients. What should I do? My patient with …(glaucoma) shows very fluctuating …(IOP) values over the last three months. I wonder if I need to change the medication? Project Studies | SoHP503 | Dr Daniela Oehring 15 Which type of evidence do I need? Evidence about “Does it work?” Effectives of an intervention or therapy Evidence: RCT, systematic review A manufacturer always tells you a product is effective! If you can't find a RCT to back this up, be wary! Evidence about “What is it like?” Peoples/patients experience, symptoms Evidence: research report using qualitative approach, interviews Evidence about “What do they do in practice?” Patient's compliance/ use of medications, treatments Evidence: studies specifically about the use or compliance, also survey, interviews, observational studies Project Studies | SoHP503 | Dr Daniela Oehring 16 Research that has not been conducted in your particular setting or patient group Research undertaken with patients in a related area For example: you want to know the physiological variation in (… (IOP) using …(GAT) for healthy Caucasian adults, but you only can access a study about the physiological variation in ….(GAT IOP) of Asian healthy eyes Research undertaken in a laboratory: For example: you want to know how much … (corneal swelling) after the application of a certain medication is expected but can only access a study with mice assessing the … (corneal swelling) behaviour with this drug Research adopted from other disciplines: For example: you want to know how much of a … (corneal) pain sensation (sensitivity) loss is expected in diabetes patients, but you only have access to a study which assessed the sensitivity loss in fingertips in diabetic patients Project Studies | SoHP503 | Dr Daniela Oehring 17 Where can I get this from? ClinicalTrials.gov Public Library of Science (PLOS) Cochrane Library Plymouth Primo NHS evidence PubMed Google Scholar ScienceDirect MEDLINE The British Library Catalogues & MedicalStudent.com Collections Merriam-Webster Dictionary Zetoc and Thesaurus NICE Project Studies | SoHP503 | Dr Daniela Oehring 18 Where can I get this from? Find out where you can get high-quality concrete details about drug information, safety information, health services, health statistics? Drug information: British National Formulary (bnf.org); US Food and Drug Administration (fda.gov) Safety information: Medicines and Healthcare Products Regulatory Agency (mhra.gov.uk); European Medicines Agency (ema.europe.eu/ema); WHO Health services: NHS; US Department of Health & Human Service (hhs.gov); WHO Health statistics: UK National Statistics (statistics.gov.uk); National centre for Health Statistics (cdc.gov/nhs/); WHO Statistical Information Service (who.int/countries/en/) Project Studies | SoHP503 | Dr Daniela Oehring 19 Key points Every time you make a decision, you need to consider what evidence you need to base your decision on There are different types of decisions and different types of evidence to use for Use in first instance research paper! If not applicable, use other rationales like ethical principles, clinical judgement Sometimes research is not directly linked to your questions Guidelines etc. should be based on research (and should be available) Use anecdotal evidence as a last resort Always remember: if you can't find any evidence, you are the best evidence available!

Project Studies | SoHP503 | Dr Daniela Oehring 21 Formulating searchable questions SoHP503 Project studies Dr Daniela Oehring Good questions & bad question Searching for evidence starts with a questions, this can be about treatment, guideline, policy, research… Think about the structure of question. What could be meant by bad in regard to questioning? What could be a bad question (not answerable)? Project Studies | SoHP503 | Dr Daniela Oehring 24 Types of questions Clinical questions can be divided into background and foreground questions Background questions: Asking about general knowledge of a topic Usually involves who, what, when, why, where or how Examples: What are the side effects of medications A or B? What causes disease C? How is virus D transmitted? Can be answered using textbooks, encyclopaedias, dictionaries, or other references source Project Studies | SoHP503 | Dr Daniela Oehring 25 Types of questions Foreground question: Applies to a specific patient or problem Examples: Will a change in contact lens material help a heavy smoker of 30 years with high myopia to gain more wearing comfort? Among children with amblyopia, does treatment with visual training affect symptoms? What is the risk of diabetic retinopathy for adults who are obese and take little exercise? Need to be answered by primary and secondary literature primary: original sources of information like journal articles secondary: interpreters of original sources like textbooks Project Studies | SoHP503 | Dr Daniela Oehring 26 Type of foreground question Aetiology: Questions of aetiology help us to determine the causes of disease (including harm caused by previous medical therapy). Diagnose: These questions help us to select and interpret the results of diagnostic tests (including taking patient histories and physical examination). Therapy: These questions help us work out the best interventions for our patients - what will deliver the most benefit and cause the least harm. Prognosis: These questions are designed to help us to estimate the likely progress or resolution of the disease, and the likelihood of any complications. Magnitude: Questions that seek to determine the size of a health problem in terms of patient numbers, or indeed the magnitude of costs associated with treating them. (EBP projects in nursing, 2001) Project Studies | SoHP503 | Dr Daniela Oehring 27 Outlook: Research question and research design Project Studies | SoHP503 | Dr Daniela Oehring 28 Breaking down the clinical scenario The PICO framework may help phrase your clinical question: P Patient/ Meaning the individual (e.g. gender, age group, Problem/Population race), the condition/ disease or the group that is the subject of the clinical question I Intervention The treatment that might be applied to the patient, problem or population C Comparison An alternative treatment that might provide similar if not greater benefits to the intervention. Please note: There might not always be a comparative intervention O Outcome The expected result of the intervention (something referred to as exposure) Evidence-Based Medicine—How to Practice and Teach EBM.

New York: Churchill Livingstone, 1997 Project Studies | SoHP503 | Dr Daniela Oehring 30 PICO Example 1 Does hand washing among healthcare workers reduce hospital acquired infections? Patient/ Problem Intervention Comparison Intervention Outcome hospital acquired hand washing no hand washing; reduced infection infection other solution; masks Project Studies | SoHP503 | Dr Daniela Oehring 31 Identifying keyword Your patient is a 72-year-old female with age-related disease. She read online that taking “antioxidant pills” from oranges and carrots may slow down the progression of the disease. She has visited your clinic for guidance on whether this is true, and if so, which are the best “pills.” Project Studies | SoHP503 | Dr Daniela Oehring 32 PICO Example 3 Your 10-year-old patient has myopia. Over the past 3 years, her myopia has increased by approximately 0.75D at each annual eye exam. The patient’s father asks whether anything could be done to prevent further increase. He read online about antimuscarinic medications and wants to know if it could be effective for his daughter. Patient/ Problem Intervention Comparison Outcome Intervention Answerable question: Project Studies | SoHP503 | Dr Daniela Oehring 36 Tips for writing a clinical question in practice P: Person, Patient, Population or Problem. Who are the relevant patients? Describe the ones that come into contact with you and are relevant to your practice. These populations might be the most relevant in writing your next clinical question. I: Intervention. What is the intervention, treatment, test etc. that you are interested in? Interventions can be types of dressings, drug therapies, placebos or counselling. Also they can be about the provision of differing environmental factors or deal with the way in which information is given to patients. They can also be diagnostic tests. Depending on what you already know about the topic you may want to investigate the name of a particular treatment or test (for example, laser treatment or lutein supplementation). Alternatively if the patient or population is relatively new, you can keep this general and ask "what intervention" rather than specifying a specific known treatment or test. Project Studies | SoHP503 | Dr Daniela Oehring 37 Tips for writing a clinical question in practice C: Comparison Intervention. Is there an alternative strategy to compare with the intervention? This can be a standard therapy, though it may also be no intervention a placebo or an alternative treatment, exposure or diagnostic test. O: Outcomes. What are the consequences of the interventions you are interested in? Make a distinction between the outcome which is relevant to your patient or problem and the outcome measures deployed in studies. Spend some time working out exactly what outcome is important to you, your patient, and the time-frame which is appropriate. Project Studies | SoHP503 | Dr Daniela Oehring 38 PICO Example 4 You are an … (Your Profession) pre-reg student on your first hospital placement on the … ward. You have been advised that between patients you must always wash your hands with medicated soap as this is the most effective means of reducing the spread of infection. However, you are sure that you have heard somewhere that an alcohol-based solution would be more effective from infection control perspective.

Phrase your question (specific, focused, clearly formulated, well defined) 2. Problem formulation (What do I need to find out?) 3. Make keywords/ phrase synonyms 4. Identify your resources (Where are your going to look for evidence? Which kind of evidence do you need?) 5. Area of evidence/ research? 6. Write down your filter strategy 7. Refine your search 8. Read the evidence and decide whether it is useful or not Project Studies | SoHP503 | Dr Daniela Oehring 90 Phrase your aims and objectives SoHP503 Project studies Dr Daniela Oehring Terminology Research question: The question which you proposed after you identified the gap in the literature using PICO (or others). Research aim: Your research aims are the answer to your research question, addressing: Why is this research necessary? What is the purpose of this study? Usually, a research project will have only one broad aim. Research objectives: Specific statements indicating the key issues to be focused on in a research project. Usually, a research project will have several specific research objectives. Research hypothesis: A prediction of a relationship between two or more variables, usually predicting the effect of an independent variable on a dependent variable. The independent variable is the variable assumed to have causal influence on the outcome of interest, which is the dependent variable Project Studies | SoHP503 | Dr Daniela Oehring 93 Research aim The aim is about what you hope to do, your overall intention in the project. It signals what and/or where you aspire to be by the end. It’s what you want to know. It is the point of doing the research. Are broad statements of desired outcomes, or the general intentions of the research, which 'paint the picture' of your research proposal Emphasize what is to be accomplished, not how it is to be accomplished Address the long-term project outcomes, i.e. they should reflect the aspirations and expectations of the research topic Do not need to be numbered Once aims have been established, the next task is to formulate the objectives. Generally, a project should have no more than two or three aim statements, while it may include a number of objectives consistent with them. Project Studies | SoHP503 | Dr Daniela Oehring 94 Research objectives The objectives, and there are usually more than one, are the specific steps you will take to achieve your aim. This is where you make the project tangible by saying how you are going to go about it. Your aims answer the question, ‘What are you doing?’ - The objectives are the answer to the question, ‘How are you doing it?’ Research objectives refer to the goals or steps that you will take to achieve your aim(s). When you write them, make sure they are SMART. Specific: talk in a precise and clear way about what you are going to do. Measurable: how will you know when you have achieved your aim? Achievable: make sure that you aren’t overly ambitious. Realistic: recognise the time and resource constraints that come with doing a dissertation project and don’t attempt to do too much. Time constrained: determine when each objective needs to be completed. Project Studies | SoHP503 | Dr Daniela Oehring 95 What is the difference between research aims and objectives? The aims of a study describe what you hope to achieve. The objectives detail how you are going to achieve your aims. Example: Aim: To understand the contribution that local governments make to national health policy. Objectives: 1. Conduct a survey of local politicians to solicit responses. 2. Conduct desk-research of local government websites to create a database of local health policy. 3. Interview national level politicians to understand the impact these local policies have had. 4. Data will be coded using a code book derived from dominant theories of governance. Project Studies | SoHP503 | Dr Daniela Oehring 96 What not to do: There are too many aims. One or two is usually enough. (I might stretch to three for other people’s projects if pushed, but I usually have only one for my own projects.) Aims and objectives waffle around, they don’t get to the point and the reader doesn’t have a clue what is intended and will be done – aims and objectives need to be concise and economically expressed. Aims and objectives don’t connect – the steps that are to be taken don’t match up with the overall intention. The aims and the objectives are not differentiated, they are basically the same things but said in different words. The objectives are a detailed laundry list rather than a set of stages in the research. The objectives don’t stack up with the research methods – in other words they are either not do-able, or what is to be done won’t achieve the desired results.
