Reduced spinal mobility

The most common measures of spinal mobility are listed below.

  • Modified Schober’s test (Figure 1): serial measures are valuable in assessing progression of spinal restriction; may be abnormal with disc disease and degenerative lumbar disease.
  • Lumbar side flexion: the best measure of overall spinal restriction and disease activity.
  • Occiput-to-wall distance: should be zero in normal people.
  • Chest expansion (at the fourth intercostal space): abnormal (<5 cm) in only a minority of patients during the first few years of disease

It is important to note that in early disease, spinal mobility may be normal.

health assessment

 MBS Items 701, 703, 705 and 707 may be used to undertake a health assessment for the following target groups:

Target Group Frequency of Service
A type 2 diabetes risk evaluation for people aged 40-49 years (inclusive) with a high risk of
developing type 2 diabetes as determined by the Australian Type 2 Diabetes Risk Assessment Tool
Once every three years to an eligible patient
A health assessment for people aged 45-49 years (inclusive) who are at risk of developing chronic disease Once only to an eligible patient
A health assessment for people aged 75 years and older Provided annually to an eligible patient
A comprehensive medical assessment for permanent residents of residential aged care facilities Provided annually to an eligible patient
A health assessment for people with an intellectual disability Provided annually to an eligible patient
A health assessment for refugees and other humanitarian entrants Once only to an eligible patient
A health assessment for former serving members of the Australian Defence Force Once only to an eligible patient

A health assessment means the assessment of a patient's health and physical, psychological and social function and consideration of whether preventive health care and education should be offered to the patient, to improve that patient's health and physical, psychological and social function.

Health assessments are not available to people who are in-patients of a hospital or care recipients in a residential aged care facility (with the exception of a comprehensive medical assessment provided to a permanent resident of a residential aged care facility).

Before a health assessment is commenced, the patient (and/or the patient's parent(s), carer or representative, as appropriate) must be given an explanation of the health assessment process and its likely benefits. The patient must be asked whether they consent to the health assessment being performed. In cases where the patient is not capable of giving consent, consent must be given by the patient's parent(s), carer or representative. Consent to the health assessment must be noted in the patient's records.

A health assessment must include the following elements:

  1. information collection, including taking a patient history and undertaking or arranging examinations and investigations as required;
  2. making an overall assessment of the patient;
  3. recommending appropriate interventions;
  4. providing advice and information to the patient;
  5. keeping a record of the health assessment, and offering the patient a written report about the health assessment, with recommendations about matters covered by the health assessment; and
  6. offering the patient's carer (if any, and if the general practitioner considers it appropriate and the patient agrees) a copy of the report or extracts of the report relevant to the carer.

A health assessment may only be claimed by a general practitioner.

A health assessment should generally be undertaken by the patient's 'usual doctor'. For the purpose of the health assessment items, 'usual doctor' means the general practitioner, or a general practitioner working in the medical practice, which has provided the majority of primary health care to the patient over the previous twelve months and/or will be providing the majority of care to the patient over the next twelve months.

A health assessment should not take the form of a health screening service.

A copy of the Health Assessment must be retained for a period of 2 years after the date of service.

MBS health assessment items 701, 703, 705, 707 must be provided by a general practitioner personally attending upon a patient. Suitably qualified health professionals, such as practice nurses or Aboriginal and Torres Strait Islander health practitioners, employed and/or otherwise engaged by a general practice or health service, may assist general practitioners in performing health assessments. Such assistance must be provided in accordance with accepted medical practice and under the supervision of the general practitioner. This may include activities associated with:

- information collection; and

- providing patients with information about recommended interventions at the direction of the general practitioner.

The general practitioner should be satisfied that the assisting health professional has the necessary skills, expertise and training to collect the information required for the health assessment.

General practitioners should not conduct a separate consultation for another health-related issue in conjunction with a health assessment unless it is clinically necessary (ie. the patient has an acute problem that needs to be managed separately from the assessment). The only exception is the comprehensive medical assessment, where, if this health assessment is undertaken during the course of a consultation for another purpose, the health assessment item and the relevant item for the other consultation may both be claimed.

Items 701, 703, 705 and 707 do not apply for services that are provided by any other Commonwealth or State funded services. However, where an exemption under subsection 19(2) of the Health Insurance Act 1973 has been granted to an Aboriginal Community Controlled Health Service or State/Territory Government health clinic, items 701, 703, 705 and 707 can be claimed for services provided by general practitioners salaried by or contracted to, the Service or health clinic. All other requirements of the items must be met.

Item 10990 or 10991 (bulk billing incentives) can be claimed in conjunction with any health assessment, provided the conditions of item 10990 and 10991 are satisfied.

Head lice

 

Head lice


General considerations

Most cases of head lice are asymptomatic. Head lice are detected when eggs are noticed in the hair, or when there is significant itching of the scalp and nape of the neck. Excoriations and papules can be present around the occiput and nape, and lymphadenopathy with or without secondary bacterial infection may occur.

Diagnosis of active lice infestation is confirmed by observing a moving louse. This can be achieved by wet combing. Apply a generous amount of hair conditioner to wet hair and comb with a fine-toothed comb (suitable combs are available from pharmacies). The conditioner stuns the lice and stops them crawling for about 20 minutes. Detangle the hair, divide into 3 to 4 cm sections, and comb each section. Wipe conditioner off the comb onto paper towel and look for lice and eggs (nits). In situations where head lice are common, repeat this method at regular intervals to detect head lice infestation.

Treatment

Wet combing can also be used to treat head lice (see method above; repeat daily until lice are not found); however, this method only has about a 40% success rate. Combing is easier with shorter hair styles, but shaving the head is not necessary.

The currently recommended topical insecticide treatments for head lice are:

1

maldison 0.5% topically, leave for 8 hours (not to be used for children younger than 6 months); repeat treatment in 7 days

OR

1

maldison 1% topically, leave for 30 minutes (not to be used for children younger than 6 months); repeat treatment in 7 days

OR

1

permethrin 1% topically, leave for a minimum of 10 minutes; repeat treatment in 7 days [Note 1]

OR

1

pyrethrins 0.165% + piperonyl butoxide 1.65% topically, leave for a minimum of 10 minutes; repeat treatment in 7 days.

Repeat head lice treatment in 7 days.

A number of proprietary products are marketed for the treatment of head lice; however, some do not contain one of the insecticides listed above.

Use the wet combing method the day after each treatment to check for live lice. If live lice are found despite treatment that has been correctly applied, the head lice are resistant to the product used (see Treatment failure).

In between treatments, use the same wet combing method twice, removing all eggs less than 1.5 cm from the scalp with the fine-toothed comb or by pulling them off with fingernails. The presence of eggs more than 1.5 cm from the scalp indicates previous, not active, infestation.

Wet combing should be repeated weekly for several weeks after cure to detect recurrence.

Wash pillow cases on hot cycle, and combs and brushes in hot water (60 C). Examine household members and close contacts and treat if live lice are found. When head lice are detected, notify the child’s school of the infestation. It is not necessary to exclude children from school after the initial treatment of head lice.

Treatment failure

Resistance to all topical insecticides is increasing, and can cause treatment failure. However, incorrectly applied treatment or re-infestation are also causes of treatment failure.

For head lice that are resistant to one of the recommended topical insecticides above, use:

1

a different topical insecticide from the list above

OR

2

the wet combing method (see above).

Occlusive products containing dimeticone have been used to treat head lice. While good quality data to support the use of dimeticone are lacking, it appears to be a safe alternative to topical insecticides without the risk of resistance, and may have a role when topical insecticides have failed. As with topical insecticides, repeat dimeticone application in 7 days.

If head lice are refractory to all of the treatments above, use:

ivermectin (adult and child 15 kg or more) 200 micrograms/kg orally with fatty food, as a single dose; repeat dose in 7 days

Alcohol home detox

How to do a home detox 

 

 

At the first appointment, it is recommended that you obtain some baseline observations and blood tests. This should include full blood count, urea and electrolytes, liver function, iron studies, glucose, calcium, magnesium and phosphate. 


Screen patients with the following questionnaires: 

• Alcohol Use Disorders Identification Test  (https://patient.info/doctor/alcohol-usedisorders-identification-test-audit)

 • Severity of Alcohol Dependence Questionnaire (http://php.nhs.uk/wp-content/uploads/ sites/26/2013/11/SADQ.pdf)

 • Kessler Psychological Distress Scale  (https://www.tac.vic.gov.au/files-to-move/ media/upload/k10_english.pdf). 


To save time, the patient can take these questionnaires home and bring them back to their follow-up appointment. If you are considering a medicated detox, guidelines suggest starting the patient on oral thiamine 200 mg for two weeks before starting the detox. This reduces the risk of Wernicke’s encephalopathy. For low-risk continuing drinkers 100 mg thiamine daily is generally enough. 

Diazepam can be used in a weaning regimen (Table) over several days to reduce the risk of seizures and withdrawal syndrome and to ease alcohol cravings. Oxazepam is a safer alternative if the patient has concurrent liver impairment, as it does not require hepatic oxidation.
