Title: EBM
1EBM
- Definition from center for evidence based
medicine-oxford -UK - Evidence-based medicine is the conscientious,
explicit and judicious use of current best
evidence in making decisions about the care of
individual patients
2What is evidence-based medicine (EBM)?
- EBM is the integration of the best research
evidence with clinical expertise and patient
values. - Best research evidence accurate and unbiased
answer to a question - Clinical experience means the skills we have
learned during our practice our ability to
elicit our patients preferences and goals.
3EBM
- A very Important objective is to predict the
outcome - However , There will be always a debate about
what is the most desirable outcome, especially
when individual factors are discussed as quality
of life and value of life judgments
4- Evidence-based guidelines
- Evidence-based guidelines (EBG) is the practice
of evidence-based medicine at the organizational
or institutional level. This includes the
production of guidelines, policy, and
regulations. This approach has also been called
evidence based healthcare - .
- Evidence-based individual decision making
- Evidence-based individual decision (EBID) making
is evidence-based medicine as practiced by the
individual health care provider. There is concern
that current evidence-based medicine focuses
excessively on EBID
5- Generally, there are three distinct, but
interdependent, areas of EBM. The first is to
treat individual patients with acute or chronic
pathologies by treatments supported in the most
scientifically valid medical literature. Thus,
medical practitioners would select treatment
options for specific cases based on the best
research for each patient they treat. The second
area is the systematic review of medical
literature to evaluate the best studies on
specific topics. This process can be very
human-centered, as in a journal club, or highly
technical, using computer programs and
information techniques such as data mining.
Increased use of information technology turns
large volumes of information into practical
guides. Finally, evidence-based medicine can be
understood as a medical "movement" in which
advocates work to popularize the method and
usefulness of the practice in the public, patient
communities, educational institutions, and
continuing education of practicing professionals. - source www.wikipedia.com
6- In order to practice EBM we need to first
appreciate that we dont always know all the
answers to our clinical questions. Once that fact
has been appreciated, the following five skills
need to be mastered.
7- To be able to ask a clinical question in a way
that captures the essence of the problemlt is
structuredlt and is most likely to yield an
answer. (PICO FORMAT ) - To be able to search for an answer (the
evidence) to our question in a way that is most
efficient. - To be able critically appraise the evidence.
- To apply the evidence to the patient.
- To monitor our own progress.
81-Asking the right questions
- P Patient
- I Intervention , Exposure
- C Comparison
- OOutcome
- Example
- P post partum mothers with psychoses
- I ECT was used as a treatment
- C Compared to another group who used
antipsychotic as a treatment - O Rapid improvement of clinical symptoms
92- Searching for the Evidence
- The Hierarchy of Evidence ( From Top to Bottom )
- RCTs systematic review of two or more Randomized
control trails - Single RCT
- A quasi experimental study without Randomization
- Observational studies Case Control-Cohort)
- Case report and series
- Expert Opinion
10Notice that
- Evidence-based medicine has demoted ex cathedra
statements of the "medical expert to the least
valid form of evidence. All "experts" are now
expected to reference their pronouncements to
scientific studies.
112- Searching for the Evidence
- Searching online Medical Literature
- Boolean Operators
- Searching PubMed
- Tags
- MESH (Medical Subject Heading) Technology
123- Critical appraisal is the study valid ? Is
the study important?
- Points to remember From epidemiology and
statistics - Which study is considered the Gold standard in
study designs ? - P value as a measure of significance (which is
more significant 0.05 or 0.01 ) - Remember a positive or negative correlation
doesn't always means a significance - Remember that Double blind RCTs cant be used to
evaluate the effects of a toxic substance ! - A Case control study is more useful for rare
outcomes , while a cohort study is useful for
rare exposure - Odds ratio is the measure of effect in case
control studies , while relative risk is the
measure of effect in cohort - An important difference between confounding and
bias is that confounding is a property of real
life situation while bias is an error the
researcher introduces into the design of the
study
13Measuring Performance and implementing EBM
- Guidelines can be considered a top-down
approach to evidence based practice .particularly
useful when there is - A Clear evidence that intervention in is
effective in a given condition - There is a wide national variation in practice
- Examples from MOH Guidelines for ECT
-Guidelines for Management of severe behavioral
disturbance-Guidelines for seclusion restraint-
Guidelines for Lithium /Clozapine Use
14Measuring Performance and implementing EBM
- Audit
- Is an attempt to measure actual clinical practice
against a number of standards of good clinical
care - There is evidence that audit improves adherence
to clinical guidelines and also improve patients
outcome. - Audit Committee at MHS
15- Monitoring and Evaluation
- Role of MHIS
- The importance of Evidence Based Planning /
Evidence Based Management in Mental Health .
16What is a mental health information system ?
- A mental health information system (MHIS) is a
system for collecting, processing, analyzing,
disseminating and using information about a
mental health service and the mental health needs
of the population it serves.
17What are the main stages of MHIS?
- (i) Collection gathering of data.
- (ii) Processing movement of data from the point
where it can be collated and prepared for
analysis. - (iii) Analysis examination and study of the
data. - (iv) Dissemination communication of the results
of the analysis. - (v) Use application of the data to improve
service delivery, planning, development and
evaluation.
18Reporting Systems , Information Systems ,
research projects
- Reporting system data flow from top to bottom
,(e.g. local areas to central governments) and
hardly any data return to those who collected
them in first place - Research Projects a stand alone project , that
focus on a particular issue (e.g. epidemiology)
such information is too detailed or too specific
to be used in an information system - Information System sustainable methods of
gathering , analyzing disseminating and using
information that are built into the workings of a
metal health service , they are designed and
implemented by those who continue to participate
in the mental health services , its panning ,
management, delivery , and evaluation
19- At your clinical facility is there any difference
between MHIS (Mental Health information system )
HMIS(Hospital Management information system )? . - Most of the time the answer would be Yes.. Why ?
- Define EMR Electronic Medical Record
20What types of information should be collected?
- To help MHIS planners make these decisions, it is
necessary to distinguish between the different
types of information needed - Episode-level information is required to manage
an individual episode of service contact - Case-level information is required to care for an
individual service user - Facility-level information is required to manage
the specific service facility (whether the
facility is a specialist institution, a mental
health ward in a general hospital, a community
mental health team, or a primary health care
(PHC) clinic) and - Systems-level information is required to develop
a policy and a plan for the mental health system
as a whole.
21Using indicators
- MHIS use a number of well-defined indicators.
Indicators are measures which (i) summarize
information relevant to a particular phenomenon
(ii) can be used to indicate a given situation
and (iii) can therefore be used to measure
change. - In the context of mental health care, indicators
are measures that summarize information relevant
to the mental health service and the population
that it serves. As an important way of measuring
change in a system, they are an essential tool in
an MHIS. - It is necessary to make a distinction between
indicators and raw data (or data elements). What
distinguishes indicators from raw data is that
indicators are aggregates of the minimum data
that have a denominator. Both indicators and
minimal data have value for information systems.
At a case-level transaction data). At a system
level, data need to be converted into indicators
to enable overall service planning and policy
evaluation. - Indicators can be used to measure various aspects
of the mental health system - Needs
2.Inputs - 3. Processes
4.Outcomes
22Examples for indicators
- Needs the population for mental health Care (
percentage of population that belongs to
vulnerable groups ) - Input the resources that are put into the mental
health are system (e.g. human resources finances
medication )examplenumber of mental health
professionals per 100.000 population - Processes activities of the service (e.g.annual
number of admissions to mental hospitals per 100
000 population ) - Outcomes the effect of the service on the mental
health of the population being served (e.g.
reduction of symptoms , percentage of
discharges) - For more examples review the monthly indicators
from MHIC on the website for MHS
23What are the benefits of an MHIS?
- An MHIS is a planning service delivery tool to
improve effectiveness, efficiency and equity. - As a planning tool
- ?It can offer a way of providing accurate,
consistent information about a mental health
service. - ?It helps improve coherency of planning rational
planning is not possible without accurate
information. - ?It is an essential tool in policy implementation
and evaluation. Without accurate information,
policy-makers cannot assess whether policy
objectives are being achieved. - As a service delivery tool
- ?It can assist service providers by recording and
monitoring the needs of individual service users. - ?It provides a means of reporting the
interventions that are used, and can thus be
linked to the ongoing improvement of service
quality.
24- Effectiveness By including indicators explicitly
determined by the policy framework of the mental
health service, the MHIS provides information on
whether and to what extent the stated aims and
objectives of the service are being met. For
example, if a policy objective is to integrate
mental health services into primary health care,
the MHIS can be used to assess the extent to
which this is in fact happening. Similarly, by
monitoring the clinical interventions that are
being used, service providers can continually
assess their effectiveness. - Efficiency By providing the means to assess
input, process and outcome components, the MHIS
provides some measures on how well resources are
being used. Importantly, information can be used
to secure appropriate levels of funding for the
mental health service. - Equity By explicitly measuring need and
coverage, the MHIS addresses a central challenge
facing the mental health service providing
equitable care with scarce resources. The MHIS
can improve accountability both within the
organization as well as to people with mental
disorders, their families and advocacy groups.

26Qualitative studies
- Qualitative studies are usually used to measure
benefits or attitudes in situations where
quantitative research would be less meaningful or
impractical. Results are usually presented as
text without numbers or figures in a way which is
intended to preserve the richness of the data in
its rightful context. - example, What are the attitude of patients with
borderline PD to their diagnosis? might be
answered better by describing what the patients
actually said than by performing a survey and
summarizing attitudes on a scale with medians and
inter-quartile ranges. - Example Focus Groups
