Meta-analysis topic ideas in geriatrics and palliative care

Older adults are the main users of health care and are under-represented in many trials. That leaves geriatrics with a literature full of complex interventions (multicomponent programmes, deprescribing, comprehensive assessment) and with outcomes that matter to people but are hard to pool: function, falls, cognition, hospital admission and the quality of death.

Palliative care adds ethical and practical limits on research: trials are small, people drop out because they die, and outcomes are often symptoms rated by patients or carers. A review in these areas needs to be explicit about missing data and about whose outcomes were counted.

Where gaps tend to hide in geriatrics and palliative care

Deprescribing and polypharmacy

Interventions that stop or reduce medicines are tested with outcomes such as falls, hospital admissions and mortality, but the interventions differ in kind. Pooling by type of intervention and setting is a recurring need.

Falls and frailty

Exercise, multifactorial assessment, vitamin D and technology for older adults are studied in many trials with different definitions of falls and frailty.

Dementia care

Non-drug approaches to agitation, caregiver support and care-home models are studied in cluster trials, which need specific methods for pooling.

Palliative and end-of-life care

Early palliative care, symptom management and advance care planning are studied with outcomes such as quality of life, symptom burden and place of death.

Care transitions and settings

Hospital at home, discharge planning and care-home interventions vary across health systems.

Outcomes and effect measures that pool well in geriatrics and palliative care

Falls: rate ratios using the number of falls per person-time, and risk ratios for the proportion who fall at least once. They are different outcomes and should be pooled separately.
Function and frailty scores (Barthel Index, Short Physical Performance Battery, Clinical Frailty Scale): standardized mean differences if scales differ, with the minimal important difference recorded.
Hospital admission, readmission and mortality: risk ratios or hazard ratios, with competing risks stated when death precedes the event.
Cognitive tests (MMSE, MoCA, ADAS-Cog): mean differences or standardized mean differences, noting that scores in dementia change slowly.
Symptom and quality-of-life scales in palliative care: standardized mean differences, noting the missing data caused by deaths.

Common traps in geriatrics and palliative care reviews

Treating cluster-randomized trials as if individuals were randomized, which overstates precision unless the design effect is accounted for.
Missing outcome data because participants died or became too unwell, which is often not random.
Pooling multicomponent programmes that share a name but not the components.
Reporting falls as a single measure when trials report rates and proportions differently.
Excluding the oldest or the frailest in the primary studies, then generalising to them.

Check before you commit

Before committing months to a topic, check that nobody has beaten you to it. Search PubMed with its systematic review filter, the Cochrane Library, the PROSPERO register (for reviews that are registered but not yet published) and Epistemonikos. Look at how recent the latest review is and whether new trials have appeared since its search date. Step-by-step guide.

Questions

How do I include cluster-randomized trials?

Use the effective sample size by adjusting for the intracluster correlation if the trial did not, or pool effect estimates that already account for clustering. State which you did.

How do I check whether a geriatrics meta-analysis already exists?

Search PubMed with the systematic review filter, the Cochrane Library (Cochrane Dementia and Cognitive Improvement, Cochrane Effective Practice and Organisation of Care, and Cochrane Pain, Palliative and Supportive Care), PROSPERO and Epistemonikos.

How do I handle death as a missing outcome?

Think about what the question is. For symptoms among survivors, report that; for composite outcomes that include death, use methods that handle the competing risk. Say clearly what the estimate means.
