Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In participant practices, when any patient book an appointment the Doctor Control Panel (DCP), as part of its standard preventative health communication with clinical software, compares demographic and clinical data in the patient’s electronic clinical record with authoritative guidelines for preventive services including immunisations. If the DCP identifies that the patients meets the follow conditions:
• Any of the target diagnoses (IMID) are identified in the patient’s list of health problems,
AND
• no record of refusal of the relevant vaccine is documented,
AND
• there is no record of contraindication to the relevant vaccine,
AND
• if the visit is in the influenza vaccine season (April to July in Australia) and there is no record of the administration of that season’s influenza vaccine,
OR
• the recommended number of doses of pneumococcus vaccine is not recorded,
OR
• a herpes zoster vaccination is not recorded,
and the practice is already able to contact the patient by SMS, the DCP will automatically send a brief and generic immunisation reminder SMS upon the patient booking an appointment, and another brief generic reminder SMS on the day of the appointment. When they arrive for an in-clinic consultation they will also receive from the receptionist a reminder letter printed automatically by the DCP. The reminder explains why each outstanding preventive service is recommended and encourages the patient to ask about those services during the current consultation with the GP. Patients who cannot be contacted by the practice via SMS, but who do come to the clinic for their consultation, will receive one printed immunisation reminder.
The same software will also be used to remind GPs electronically about the immunisation status of these patients during the subsequent consultation. The DCP will open a window on the computer screen including a list of recommended preventive activities, either they are due or not, with links to current guidelines and easy access to the corresponding fields in the patient’s health record.

Before the introduction of reminders, GPs and nurses from participant practices will have an educational activity for up to one hour about the immunisation needs of patients with IMID.

In the end of two influenza seasons, i.e. 18 months from the beginning of the study, the researchers will receive from the practices aggregated tabulated results, in the form of total numbers: number of patients in the practice; by sex; five year age groups, type of medical condition, number of patients eligible for the study (i.e. those who have a relevant condition but haven’t received the relevant vaccination); the number of patients who received the reminder; and the number of eligible patients who received the vaccination. The same aggregated results, except those numbers related to reminders, will be received from control practices, and from all practices for years 2013-2018 to provide a baseline for comparison.
We will then analyse influenza, pneumococcus and herpes zoster vaccination coverage among patients with IMID before and after the introduction of reminders. We will analyse the proportion of each practice’s eligible patients who had been immunised at baseline and the proportion who have been immunised by the end of the study, after the use of reminders. We will examine aggregated results according to characteristics of patients and practices. All results will be non-identifiable.
Results will be analysed using descriptive statistics and McNemar paired test for binary outcomes. Comparisons between intervention and control practices will be performed using Qui-square test. Statistical analysis will be performed using the software Stata 15.0.

Data on GPs and registered nurses confidence in vaccination recommendations for patients with immune-mediated inflammatory conditions will be collected in the beginning of the study (before the use of reminders), soon after the educational activities, and in the end of the study (18 months from the beginning of the study).

The SMS for patients at booking is presented below:

Dear [Patient Name], I look forward to talking with you at [time] on [day and date]. Our records indicate that your [influenza and/or pneumococcal and/or herpes zoster] vaccination is due. Please ask me about this when you attend at your appointment if you wish to discuss immunisation. Kind regards, [Dr. GP Name]
...............................................................................................................................

The SMS for patients on the day of appointment:

Dear [Patient Name], Just a reminder of your appointment today at [time]. Our records indicate that your [influenza and/or pneumococcal and/or herpes zoster] vaccination is due. Please ask me about this when you attend at your appointment if you wish to discuss immunisation. Kind regards, [Dr. GP Name]
...............................................................................................................................

Two examples of patient printed reminders (that will be given to the patient in the waiting room) are presented below.

Example 1 of patient reminder:

Important information about immunisations for Ms. Test Patient

Dear Test, 09/07/2018

We want to help you to stay well. The advice below is based on the information that we have in your record. If any of it is incorrect, please tell me.

We have diagnosed you with rheumatoid arthritis.

Rheumatoid arthritis and some of the medicines that are commonly used to help to treat it increase your risk of becoming seriously unwell from infections. These infections include influenza (the flu), which can put you out of action for several weeks, and invasive pneumococcal infection, which can cause pneumonia and septicaemia (infection of the blood stream).

You are also at higher than average risk of developing shingles (herpes zoster).

The good news is that we can help you to decrease your risk of these serious illnesses by immunising you against these infections.

We have no record of pneumococcal vaccine, influenza vaccine or herpes zoster vaccine for you.

Influenza vaccine is available for you free of charge and we should give it to you every year. The best time to receive it is in May.

We have to prescribe pneumococcal vaccine for you, and it costs about $40, or if you have a Heath Care or pension card $6.40, from pharmacies.

Please ask me whether your condition and its treatments allow you to receive the vaccine to prevent shingles.

Please ask me about these immunisations when we meet in a few minutes.

Example 2 of patient reminder:

Important information about immunisations for Ms. Test Patient

Dear Test, 09/07/2018

We want to help you to stay well. The advice below is based on the information that we have in your record. If any of it is incorrect, please tell me.

We have diagnosed you with ulcerative colitis.

Ulcerative colitis and some of the medicines that are commonly used to help to treat it increase your risk of becoming seriously unwell from infections. These infections include influenza (the flu), which can put you out of action for several weeks, and invasive pneumococcal infection, which can cause pneumonia and septicaemia (infection of the blood stream).

You are also at higher than average risk of developing shingles (herpes zoster).

The good news is that we can help you to decrease your risk of these serious illnesses by immunising you against these infections.

Influenza vaccine is available for you free of charge and we should give it to you every year. The best time to receive it is in May. You received the influenza vaccine on 24/5/2017. We should give you this year’s influenza vaccine today.

You received a first dose of pneumococcal vaccine on 15/03/2015. We should give you the second dose today or at your next visit. We have to prescribe pneumococcal vaccine for you, and it costs about $40 from pharmacies.

We have no record of shingles (herpes zoster) vaccine for you. Please ask me whether your condition and its treatments allow you to receive the vaccine to prevent shingles

Please ask me about these immunisations when we meet in a few minutes.

Summary
Brief summary
This study aimed to investigate the current vaccination coverage for influenza, pneumococcus, and herpes zoster amongst patients affected by immune-mediated inflammatory disease (IMID) and increase vaccination rates using targeted electronic and printed patient immunisation reminders, electronic health practitioner immunisation reminders, and educational activities in Australian general practice. Patients affected by IMID (rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, or inflammatory bowel disease) attending Australian general practice will be included in the study. Current vaccination coverage will be estimated based on de-identified data on influenza, pneumococcus and herpes zoster vaccinations for patients with IMID from all practices using the Doctors Control Panel (DCP) for 2013-2018, which accept to be part of the study. DCP is a well-established software package that retrieves medical information from electronic medical records and identifies preventive health care activities that are due.
In the second part of the study, DCP will generate targeted electronic (SMS text message upon consultation booking and another on the day of the appointment) and printed (read in the waiting room) patient immunisation reminders to inform them about their higher risk of viral and bacterial infections and generate advice about recommended vaccines. All communication will be via the recruited practices, without intervention by the researchers.
Patients who have agreed to receive SMS messages from the practice will receive a generic reminder SMS upon booking, and another generic reminder SMS on the day of their appointment. They will also receive a printed letter if they arrive for an in-person consultation. Patients who have refused to receive SMS messages from the practice or who don’t have a mobile telephone will not receive SMS text messages but will receive a printed reminder letter from the receptionist if their consultation with the GP is in the clinic. The DCP will also generate electronic GP immunisation reminders (GP computer) to inform them about patient's status regarding immunisation. The outcome measures at the end of the intervention (18 months including two influenza vaccination seasons) are 1) recorded administration of influenza, pneumococcus, and herpes zoster vaccines to patients with IMID, and 2) documented contraindications to, or refusal of, those vaccines.
Compared to the baseline (Stage 1), we expect an improvement of at least 20% in vaccination coverage after the intervention (Stage 2).
