25
Q

What are 5 things to do if a person has had acute sinusitis symptoms for <10 days?

A
  1. Do not offer antibiotic prescription
  2. Advise that acute sinusitis usually caused by virus and only complicated by bacterial infection in about 2 in 100 cases. takes 2-3 weeks to resolve, most will get better without abx
  3. Symptoms can be managed with self care: paracetamol, ibuprofen, nasal saline/ nasal decongestants (lack of evidence for these though). NHS website for instructions on using salt water to ease congestion
  4. No evidence for oral decongestants, antihistamines, mucolytics, steam inhalation, warm face packs
  5. Seek medical advice if rapid worsening or don’t improve after 3 weeks, or become systemically very unwell
26
Q

What are 4 aspects to management of acute sinusitis that has lasted >10 days?

A
  1. Prescribe high dose nasal corticosteroid for 14 days for adults and children >12y e.g. mometasone 200mcg bd
  2. Consider no abx or back up prescription
  3. If back up prescription given, advice about managing symptoms with self care, use prescription if worsen rapidly or significantly, or don’t improve within 7 days
  4. Advise to seek medical advice if develop complications, symptoms rapidly deteriorate, don’t improve within 3-5 days of initial treatment, or stop abx treatment because not tolerated
27
Q

What is the suggested regime for nasal corticosteroid for acute sinusitis lasting >10 days (adults and children >12y)?

A

Mometasone 14 days, 200micrograms twice a day

28
Q

What are 3 things to remember when prescribing nasal steroids for acute sinusitis >10 days?

A
  1. It may improve symptoms but not likely to affect how long symptoms last
  2. Could cause systemic effects, paticularly in people already taking another corticosteroid
  3. May be difficult for people to use correctly
29
Q

What are 4 things to remember when deciding whether to prescribe antibioitics for acute sinusitis lasting >10 days?

A
  1. Evidence that antibiotics make little difference to how long symptoms last, or proportion of people with improved symptoms
  2. Withholding antibiotics is unlikely to lead to complications
  3. Possible adverse effects, particularly diarrhoea and nausea
  4. Factors that might make bacterial cause more likely - symptoms >10days, discoloured/purulent discharge, fever >38 etc
30
Q

What are 2 things to advise patients about if a back up antibiotic prescription is given for sinusitis?

A
  1. Managing symptoms with self-care measures
  2. Using back-up prescription if symptoms worsen rapidly or significantly, or do not improve within 7 days
31
Q

What are 3 things to consider when reassessing patients?

A
  1. Alternative diagnoses such as dental infection
  2. Signs or syptoms of more serious illness or condition

seek specialist advice first, as evidence for this approach is limited
