Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites

Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.
3. Definition
• An optical dispensing is sub specialty of
optometry which includes all procedures from
the time the glass prescription is presented to
the optician, till the patients are on with the
pair the glasses satisfactorily.
5. Determining facial wrap
Broadly, there are six face shapes that we
observe around the world.
Oval
Round
Square
Rectangle
Triangular
Heart
6. Oval Face shape
Oval face shape is the most common face shape
and is considered as an ideal one
recommend oversized or rectangular frames
7. Round Face shape
Round faces are usually proportional to width
and length that features your full cheeks and a
broad forehead.
recommended rectangular or angular frames
for round face shaped persons.
8. Square Face shape
• Square faces are characterized by a broad
squares forehead and a strong jaw line.
• We recommended Round or Oval shaped
frame.
9. Rectangle face shape
• Rectangle faces are regarded as the elongated
proportion that means a longer, narrower face
and nose, along with the
same strong jaw line and
squares forehead.
• We recommended round
or cat eye shaped
10. Triangle face shape
• Triangle face have a narrow forehead, but
wider cheek.
• These faces look the best in top heavy styles
which help balance out the jaw.
11. Heart face shape
• Heart shaped faces have a broad forehead and
narrow jaw line or small chin.
• We recommended deep vertical frame shaped
frame.
13. Datum system
• Previously used system for measuring lenses,
was established as a system of reference points
for the frames & lenses
so that position of lens optical centres & bifocal
segment heights would be consistent
14. Boxing System
• In 1962 the optical manufacturers association
adopted the boxing system to provide a
standard
for frame and lens measurement that greatly
improved upon the accuracy of previous
systems.
• The boxing system is based upon the idea of
drawing an imaginary box around a lens shape
with the box’s sides tangent to the outer most
edges of the shape.
17. “A” MESURMENT
• It is measured as the horizontal distance
between the furthest temporal and nasal edges
lens shape of the box.
• This is measured in millimetres
18. “B” MESURMENT
• It is measured as the vertical distance between
the furthest top and bottom edges lens shape
of the box.
21. • Facial wrap
facial wrap the frame fills properly
following
the curved line of the face.
• Pantascopic tilt
Pantascopic tilt is the angle between
the normal
to the temple and frame front.
• Vertex distance
Vertex distance is the distance
between the front
of the cornia and back of the lens.
23. PD Ruler Method
• Sit directly opposite the patient (arm’s length)
• Position yourself 40cm in front of the patient.
• Eyes are level.
• Place ruler on the bridge of the patient’s nose
• Hold pen torch under your left eye directed
at the patient’s RE
24. • The dispenser aligns the zero mark
of the
demo lens with the centre of patient’s
pupil.
• The PD for distance is read as the
mark falling
on the left pupil.
25. The Pupilometer method
• Fast and accurate measurement
for monocular and binocular
PDs.
• The variation between
the visual axes and
pupil centre.
26. Pupilometer
• Procedure:
Hold the instrument in both hands and rest the
pupilometer
on patients face.
Ability to vary working distance from 20cm to
infinity
Internal hairline moved until line and corneal
reflection are
coincident
Corneal reflection typically located nasal to pupil
center (2
to 5 )
28. Direct pupillary reflex marking
A pen torch will produce clear corneal
reflections.
Position yourself 40cm in front of the patient.
Eyes are level
Hold a pen light under your left eye, aiming
the light at the patient’s eye.
Mark the patient corneal reflex in marker.
30. Layout card measurment
• Measure monocular PD. The recommended
procedure is the use of a pupillometer.
• Incorrect PD may cause difficulty in using
different zones through the lens.
33. Lens material
Traditionally, people used to prefer glass lenses. But
they have become less popular now due to the
danger of breaking. They are also heavier in weight
than alternatives. These days, CR-39 plastic lenses
are the preferred material for spectacle lenses.
It is safer, cost effective and offers an outstanding
optical quality. some people would be satisfied
with just that-a cheap good quality lens which can
correct vision.
34. • People become more aware, they’ve
started
realizing there is more to it than it appears.
Like UV protection, even lighter weight,
35. Lens Coating
• Every good lens has 3-4 coatings,
• Each of a microscopic thickness.
• Most common of coatings is for toughening the
lenses to make it break-resistant.
• Then UV protection coating and Scratch resistant.
• Lastly, there is the anti-reflective coating
Primarily helps in reducing the
effect of reflective light from
bright objects such lamps or
car headlights at night.
36. UV Protection and Polarized
lens
This is one of the major deciding factors. UV
exposure has been clinically proven to be an
important cause of cataract because of its
oxidative effects on humans.
37. Photo chromatic
• A major breakthrough in the area of absorptive
lenses took place in 1964 with the invention of
corning’s photo gray photo chromatic.
• These lenses darken when exposed to light.
• photo chromatics are available in both glass
and plastic material.
38. Tinted lenses
• A tint is usually associated with a certain
quantity and depth of color, the depth of color
is described as density of lens.
• Both glass and plastic lenses can be tinted to
achieve the desired color.
39. Ophthalmic Lens fitting
Laying off
• Before a lens is edged it must be marked so
that cylinder axis if any is set according to
prescription and its optical centre is in correct
position relative to lens shape.
• We use a lenso meter to mark three dots
indicating optical centre position and the
horizontal meridian.
40. • These horizontally placed dots are used to
set
the lens on correct axis.
• In case of bifocals and trifocal and trifocals
the
three dots should be parallel to top of the
segment.
41. Lens cutting
• Once the lens is layed off it must now be cut
into desired shape.
42. Edging formers
• Shanking tongs were then used
to crumble the edge away until
it roughly resembles eye shape.
44. Flat Edge
• This is the simple form of edge.
• It is mainly used for lenses fitted
to rimless mounts or as an
intermediate stage in the
production of other edge forms.
45. Bevel Edge
• The bevel edge is used for
lenses to be fitted in shall
and full rimmed frames.
• To avoid pressure on the
peak of bevel and the attendant risk of
chipping the lens
46. Mini Bevel
• The peak of a normal bevel lies approximately
midway between the two surfaces with strong
minus lenses and high cylindrical power.
47. Grooved Edge
• It is simply a flat edge with central groove.
• Used mainly on lenses fitted to spectacles of
the nylon supras or semi rimless types.
48. Hand Edgers
• A hand edger is still indispensable piece os
equipment although new automatic are being
preferred. For starting ensure that the hand edging
machine in good working condition. It should be set
up with adequate water. Hold the lens is both hands
with convex side up. Rest your hands on the dip
tray
and press the lens against the revolving diamond
wheel. Make sure to hold the lens across the wheel
and at a slight upward angle. Now slowly rotate the
lens passing the grip of lens from hand to hand.
49. • After edging match size of edged lens with the
frame. The lens is right when the shape is
exactly like that of the frame to be fitted.
• PHOTO
