Q

Define transitions of care and where they occur

A

Transitions of care occur when all or part of a patient’s care is transferred between healthcare providers, locations, or different levels of care within the same location, as the patient’s conditions and care needs change*.

Transitions occur when:
>the patient moves between locations or healthcare providers
>different levels of care within the same facility
>patient’s care is discussed during multidisciplinary rounds
>patient transfers for a test or appointment
>admission or discharge

Q

Describe why transitions of care are a time of risk for patient safety

A

> there is an increased risk of loss of critical information

> requires a high level of coordination between multiple healthcare providers especially when facilities use a mix of paperless and paper

> transitions need to focus on non-clinical issues too such as cognitive and functional status, housing, transport and carer support

Q

Identify the data arising from poor transitions of care

A

> there are often gaps/failures in care planning involving multiple teams and collaboration between inpatient and community-based teams

> communication needs to be more clear during handover, throughout documentation, and when communicating with patients and their families/carers.

> patient complaints usually involve communication, treatment, and access.

Q

Differentiate palliative care and end of life care

A

Palliative - person and family-centered care provided for a person with an active, progressive, advanced disease who has little or no prospect of cure and who is expected to die and for whom the primary goals are to optimise the quality of life.

End of life - the last few weeks of life in which a patient with a life-limiting illness is rapidly approaching death, the phase of palliative care is recognised as one where increased services and support essential to ensure quality coordinated care from the health care team is being delivered

Q

Define pain

A

An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.

Pain is whatever the experiencing person says it is, existing whenever they say it does.

Pain is subjective and the patient’s self-report is the most important indication of pain

Pain is known as the 5th vital sign

Q

Briefly discuss the pathophysiology of pain

A

> When tissue damage occurs a range of chemical mediators, pro-inflammatory cytokinases are released

> These stimulate the nociceptors which then transmit pain signals to the CNS via afferent nerves

> The signal ascends the
spinal cord along the
ascending pathways

>It is then projected into
the medulla, thalamus
and cerebral cortex of
the brain for higher
interpretation

> It is at this point that
the signal is greatly
influenced by emotion,
cognition and behaviour

> delay 3-5 days before injury is sutured

> greater access for pathogens to invade

> greater inflammation

> more granulation

> larger scars

74
Q

There are 4 phases of wound healing. What are they?

A
  1. immediate
  2. inflammation
  3. proliferation
  4. maturation
75
Q

What happens in the immediate phase of wound healing?

A

> haemostasis - prevention and stopping of bleeding

76
Q

What happens in the inflammation phase of wound healing?

A

> increased blood flow

> dedridement (phagocytosis)

> removal of cellular debris/devitalised tissues and cleaning of the wound

> macrophages and leukocytes are dominating cells

> normal duration 2-3 days

77
Q

What happens in the proliferation phase of wound healing?

A
1. Granulation:
>epithelialisation
>macrophages attract endothelial cells
>new capillaries are formed
>fibroblast increases
>collagen is produced
>red granulation tissue appears in the wound
  1. Epithelialisation
    >epithelial cells multiply and migrate across the surface from the edges
    >when epithelialisation is complete, the wound is healed
78
Q

What happens in the maturation phase of wound heailng?

A

> transformation of the reduced collagen will increase the strength of the connective tissue

> some of the capillaries formed during granulation will disappear thereby normalising blood supply

> duration - longer than a year

79

90
Q

What is wound dehiscence and what causes it?

A

A splitting open of the wound post-op usually seen in obese people.

Causes:
>infection
>a failure to achieve haemostasis with subsequent haemotoma development
>poor nutritional intake
>excessive exudate caused by an infection or localised oedema
>poor quality vascular supply caused by a chronic or acute medical condition, emboli or oedema
>mechanical stress on the wound caused by movement, obesity, oedema or localised pressure

91
Q

What is involved in a wound assessment?

A

Objective assessment:
>photography
>wound tracings
>wound assessment charts

Wounds assessment must include:
>the objective of the management of the wound
>ie. promotion of healing or palliative management

We need to look at:
>wound etiology
>pain and odour assessment
>wound site/anatomical location
>wound bed and surrounding skin appearance (periwound)
>measurement of wound depth and undermining rationale or dressing regime

92
Q

How do we classify wounds?

A

Red:
>mainly red granulation tissue
>usually a secondary intention wound

Yellow:
>covered with sloughy material consisting of necrotic tissue and fibrin it reigns yellow, brown or grey while moist
>may. Be adherent to the wound bed or edges loosely adherent and stringy

Black:
>Covered with necrotic tissue
>the necrotic tissue can be soft or can form an eschar dry black necrotic tissue

93
Q

What are the different types of exudate?

A

> serous - clear, watery plasma

> sanguineous/haemorrhagic - indicates fresh bleeding

> sanguineous/haemoserous - mixture of serous and sanguineous

> purulent - thick, yellow, green or brown fluid indicative of infection

> fibrinous - cloudy with strands of fibrin

> seropurulent - yellow, tan, cloudy

> purulent - opaque, milky, sometimes green

> hemopurulent - reddish, milky, thick

94
Q

How do we mentally prepare the patient and family for surgery

A

Talk to the patient and family about what they will look like in ICU:
>tubes, ventilation, monitors, infusions
>not able to talk - connected to ventilator
>how will pain be managed

Talk about timeframes:
>how long will they spend in ICU
>what is the anticipated length of stay (5days including day of operation)

> talk about the need for deep breathing and coughing - after surgery, its common to get collapse of the alveoli and we need to get them reinflate so they dont get post-op chest infections

> talk about the need to take analgesia post-op - without analgesia they will be in too much pain to do deep breathing and coughing which are important for reducing post-op complications

> talk about the need for early mobilisation - they need to be sitting up in bed the day after surgery and walking to the bathroom on day 2. This depends on things like age and their situation before surgery

> talk about non-weight bearing on arms

95
Q

How do we clinically prepare the patient for surgery?

A
Pre-op they will have:
>chest x-rays
>swabs for things like MRSA
>urine sample
>knowledge of co-morbidities
>spirometry
>weight and height
>allergies 
>obs
>how well they move before surgery
>recent infection
>bowel habits
>risk assessments
>discharge planning
>ECG
>dental check
>angiogram
96
Q

What is coronary artery bypass grafting and why do we do it?

A

The most common coronary bypass procedure meant for people with coronary bypass disease.

indications:
>triple vessel disease
>left main disease
>failed angioplasty

97
Q

What is cardiopulmonary bypass and when do we do it?

A

The heart is stopped, blood is warmed or cooled - when the body is cold, it needs less O2. Oxygenation and pumping of blood is continued.

indications:
>Operations requiring the opening of the chambers of the heart require the use of CPB to support the circulation during that period.

98
Q

What is off bypass coronary artery grafting and when is it done?

A

The heart is still beating so its more difficult for the surgeon to do a nice clean job on the artery.

indications:
>stenosis
>vessel disease
>angina

99
Q

What are the most common graft harvesting sites and what are their beenfits?

A

Left internal mammary (LIMA):
>also RIMA
>excellent and prolonged patency

Saphenous vein:
>easily accessible
>more susceptible to wear and tear

Radial artery:
>possible vasospasm
>prolonged patency

We almost always try to use the LIMA because it is an artery used to prolonged pressure!

100
Q

What are the complications of cardiopulmonary bypass?.

A
  1. haemodilution
  2. hypothermia
  3. anticoagulation
  4. myocardial stunning
  5. atelectasis
  6. pleural effusions
  7. deep sternal wound infections
101
Q

How do we promote secondary prevention of coronary artery disease?

A

> talk to people about their cardiac risk factors

> educate people about managing hypertension - diet, exercise, alcohol, overweight/obese, smoking, T2DM, depression

> medications - statin, asprin, ACE inhibitors, beta blockers

> provide pain relief

> ensure family and patients receive formal education about risk factors and modifications from a dietician, nurse, pharmacist, physio, psychologist and OT

> encourage participation in supervised exercise programs
