Home Medication Management and Injections
Whether drug treatment works often depends on taking medicines correctly and injecting accurately at home. Older people with several conditions take many medicines and often have low adherence, and the harm that actually happens is concentrated in a few high-risk medicines: anticoagulants, insulin, antiplatelet drugs and oral antidiabetic drugs. Our registered nurses in Hong Kong visit the home to check medicines systematically, fill pill organisers, give subcutaneous injections and teach medication use, to reduce medication harm at its source.

Common medication risks for older people at home
Polypharmacy (taking many medicines) is very common among older people, and adverse drug events (ADE) are one of the main avoidable causes of unplanned hospital admission. The problems that actually arise are often concentrated in a small number of high-risk medicines, which are the ones that most often need their dosing checked and subcutaneous injections at home. The figures below show why these cases need close nurse follow-up.
67%
Share of older people's emergency admissions for adverse drug events caused by 4 main types of medicine
National estimates from the United States show that among emergency admissions of people aged 65 and over for adverse drug events, 67% were caused by four types of medicine: anticoagulants (33.3%), insulin (13.9%), antiplatelet drugs (13.3%) and oral antidiabetic drugs (10.7%) (Budnitz et al., 2011).
47.5%
Share of older people in Hong Kong who had taken a “potentially inappropriate medication”
Research shows that 47.5% of people aged 65 and over in Hong Kong had taken a potentially inappropriate medication (PIM) within 12 months (down from 55.6% in 2006 to the 2014 level), and each person was prescribed 9.4 medicines on average (Zhang et al., 2021).
About 50%
Share of people with long-term illness who take medicines as prescribed
A WHO report states that in developed countries the average share of people with chronic illness who keep taking medicines as directed over the long term is only about half, and it is lower still in developing countries (WHO, 2003).
US$42B
Yearly global healthcare cost of medication errors
WHO estimates that medication errors cost the world about US$42 billion a year, close to 1% of total global health spending, and that they are one of the main causes of avoidable harm in health systems (WHO, 2017).
One point needs to be made clear. A “potentially inappropriate medication” is a risk indicator and does not necessarily cause harm. Research shows that the link between polypharmacy and hospital admission or inappropriate prescribing is the most consistent, while links with other outcomes such as adverse drug reactions and disability are mixed and need to be assessed case by case. In other words, the more medicines are prescribed and the more complex the regimen, the more a professional is needed to help check and simplify it systematically.
Four steps in nurse-led medication management at home
The service is built around the nursing process. It starts with a full medicine check and moves through organising, injection and medication education, reducing medication risk step by step.
- 1Medicine check (Assessment)The nurse compares the patient's past medical records with the current prescriptions in detail, checks one by one for interactions, duplicate medicines and anything that could be simplified, and reports any problems found to the doctor for review.
- 2Organising and filling pill organisers (Planning)To fit the patient's daily routine, 7-day or 28-day pill organisers are filled in advance, with the time, dose and points to watch clearly written on them. This helps the older person to take the right medicines on their own, or with a little help from family.
- 3Subcutaneous and intramuscular injections (Implementation)The nurse gives subcutaneous injections such as insulin, low molecular weight heparin and vitamin B12, and some intramuscular injections, in person. Aseptic technique is followed strictly throughout, and the nurse demonstrates and corrects the family's injection technique on site.
- 4Medication education and monitoring (Evaluation)The patient and family are taught about common medicine side effects and which medicines and foods should not be taken together. The nurse also observes and records the response after taking medicines, for the doctor to refer to when adjusting the prescription, and helps the patient build the habit of taking medicines on time.
Clinical evidence for nurse-led medication management
Having a nurse visit to check and organise medicines is supported by clinical evidence, but it must be clear which parts are proven to work and which are not yet proven.
Effects supported by research
- A pooled analysis of 19 randomised controlled trials (RCTs, 4,805 people in total) found that medication reviews led by pharmacists or nurses lowered the risk of medication-related readmission to RR 0.25 (about three quarters fewer), and lowered the risk of emergency department visits for any cause to RR 0.70 (Renaudin et al., 2016)
- A randomised controlled trial (RCT) in people aged over 80 showed that after intervention by a clinical pharmacist team, medication-related readmissions fell by about 80% and emergency visits by about 47%, and the average healthcare cost per person was also lower (Gillespie et al., 2009)
- Several studies have also confirmed that regular medication review helps patients to take medicines more punctually and accurately as directed
Where the evidence is not settled
- The same pooled analysis points out that for a composite measure such as readmission or emergency visits for any cause, no clear difference was seen (RR 0.97, p=0.47). The actual effect depends on how the intervention is delivered and on the patient's own health risk
- The study authors also point out that the overall quality of the evidence is low. A more accurate reading is therefore that the service helps most in preventing admission caused by medication problems, but cannot prevent readmission for every cause
- In addition, the relationship between taking many medicines together and adverse drug events (ADE) or disability is not consistent in current research, and needs to be assessed individually for each patient
In summary, the biggest value of having a nurse check and regularly review a patient's medicines is to prevent admission caused by taking or using the wrong medicine (that is, medication-related readmissions and emergency visits). For composite measures such as readmission for any cause, current research has no consistent conclusion, and the effect depends on the model of intervention. We therefore describe only the parts that research supports.
Subcutaneous injection of insulin and blood-thinning injections
The two types of subcutaneous injection handled most often at home are insulin and low molecular weight heparin (blood-thinning injection or anticoagulant). Each has a specific set of safety techniques that are easy to learn. On a home visit the nurse can give the injection and also demonstrate on the spot and guide the family to the correct technique.
Key points for subcutaneous insulin injection (international expert consensus)
- Use the shortest needle: whatever the age and build, a 4 mm pen needle or 6 mm syringe needle is enough. Adults using a 4 mm pen needle can insert it straight in at 90°
- Rotate the injection site every time, and do not keep injecting in the same place, to avoid lipohypertrophy (fatty lumps under the skin)
- Change the needle after each use and never reuse it, because reuse raises the risk of lipohypertrophy and pain during injection
- Lipohypertrophy makes the body absorb less insulin and makes absorption unstable, so blood glucose swings up and down. Injection sites should therefore be checked regularly
Key points for low molecular weight heparin (blood-thinning injection)
- The abdomen is the first choice of site, because subcutaneous injection into the abdomen is less likely to cause bruising than injection into the arm
- After injecting, press gently on the needle site, which helps to reduce the chance of bruising
- Pushing the medicine in more slowly, over a longer time, also helps to reduce bruising
- Put used needles straight into a sharps container. Do not put the cap back on, to avoid accidentally pricking family members or cleaning staff
Who most needs home medication management and injections?
If an older person at home meets any of the situations below, systematic medication management and injection by a registered nurse often does the most to lower the risk of something going wrong.
Older people with chronic illness taking many prescribed medicinesOlder people who usually take many medicines, see several specialists and have more long-term conditions are at higher risk of taking potentially inappropriate medications, and especially need someone to check and organise their medicines regularly.
People who need long-term subcutaneous injectionsPatients who need regular insulin, low molecular weight heparin (blood-thinning injections) or vitamin B12, and who need attention to the correct injection technique and rotation of injection sites.
Patients who need short-term injections after surgeryPatients who have just come home from hospital and need a nurse to visit and give painkiller injections, antibiotics or anticoagulants.
Families where the person is afraid of self-injection, or the family lacks nursing knowledgeFamily members often find it very stressful to give an injection to a relative and to sort out a large pile of medicines. A nurse visiting to take over and guide on the side can ease the burden on the family and help them build confidence in caring.
Frequently asked questions
Is a nurse needed for medication at home? Can the patient take medicines alone and a family member help with injections?
That can work, but the risk tends to be concentrated in a few types of high-risk medicine. National data from the United States show that two thirds (67%) of emergency hospital admissions of older people for adverse drug events were caused by anticoagulants, insulin, antiplatelet drugs and oral antidiabetic drugs. These are the medicines that most often need their dosing checked and subcutaneous injections at home. In Hong Kong, people aged 65 and over are prescribed 9.4 medicines on average, and in 2014 nearly half (47.5%) had taken a “potentially inappropriate medication”. A registered nurse visiting to check medicines, fill pill organisers and give injections helps to spot interactions and duplicate prescribing early, and to use the correct injection technique, which lowers the risk of accidents.
Does having a nurse visit to review and organise medicines really help? Or is it just reassurance?
Clinical evidence supports it, but the scope must be stated clearly. A pooled analysis of 19 randomised controlled trials found that medication reviews led by pharmacists or nurses significantly reduced medication-related readmissions (risk down by about three quarters, RR 0.25) and all-cause emergency department visits (RR 0.70). Another randomised controlled trial in people aged over 80 found that medication-related readmissions fell by about 80% and emergency visits by about 47%. The same pooled analysis also found no significant difference in a composite measure such as all-cause readmission (RR 0.97), so the actual effect depends on the model of intervention and the patient's own risk. In short, this service helps most in preventing harm from taking or using the wrong medicine, but it does not mean that readmission for every cause can be avoided.
Which medicines can a nurse inject at home? Is subcutaneous injection (insulin or blood-thinning injections) safe?
Common items include subcutaneous injections of insulin, low molecular weight heparin (blood-thinning injection or anticoagulant) and vitamin B12, as well as some intramuscular injections. Safety depends on injection technique. For insulin, international experts recommend the shortest needle (4 mm pen needle), rotating injection sites and never reusing needles, to avoid lipohypertrophy (fatty lumps under the skin), which makes insulin absorption unstable and blood glucose fluctuate. For anticoagulants (low molecular weight heparin), the abdomen is the preferred injection site, and pressing on the site after the injection helps to reduce bruising. On a home visit the nurse demonstrates on the spot and corrects the family's injection technique.
An older person is taking many medicines (polypharmacy). What are the risks, and how can a nurse help?
The most consistent research finding is that polypharmacy is closely linked to hospital admission and inappropriate prescribing (evidence for links with some other adverse outcomes is mixed and needs to be judged case by case). Hong Kong data show that the more medicines prescribed, the more the chance of exposure to potentially inappropriate medications rises, making it the strongest risk factor. A nurse can carry out a systematic medicine check on a home visit, comparing the medical record carefully with the current prescriptions, finding duplicated, interacting or simplifiable medicines, and referring the patient to the doctor for review, which lowers the risk at its source.
Medicines are being dispensed on time, so why is the condition still not well controlled?
Low adherence is a common cause. A World Health Organization report states that in developed countries the average adherence to long-term treatment of chronic disease is only about 50%. Missed doses, wrong timing or dose, or stopping medicines on one's own out of worry about side effects all greatly reduce the benefit. A nurse can fill pill organisers, provide clear medication reminders, explain what each medicine does and its side effects, and monitor the patient's response so that feedback goes to the doctor to adjust the prescription, which improves adherence and keeps the condition stable.
Medication safety matters so much. Do authoritative organisations support home medication management?
Yes. In 2017 the World Health Organization (WHO) launched its third Global Patient Safety Challenge, “Medication Without Harm”, which aims to halve severe and avoidable medication-related harm within 5 years. WHO estimates that medication errors cost about US$42 billion a year and lists them as a leading cause of avoidable harm in health systems. Putting systematic medicine checking, organising, injection and medication education in place at home is a practical response to this global challenge.
