elderly with screened positive elderly with screened positive psychological problems psychological problems
Implications for clinical practice & future Implications for clinical practice & future researchresearch
Challenges : Tip of the Iceberg Poverty (1/5 on CSSA) & ill-health (2/3
chronically ill) Suicide rate (32/100,000, 2004) of HK
elderly is second highest in the world 86% victims had psychiatric problems Elderly population survey prevalence
19% screened positive of depression 5% known psychological problems 0.4% known depression
Opportunities in PC 77% consulted within 1 month before
suicide 85% of elderly consulted at least once/yr Mean 5-8 consultations/yr Continuity of care Trusting doctor-patient relationship Whole-person care 20% elderly had psychological problems
but 48% undiagnosed
Is it important?
Is screening useful?
Is PST-PC effective?

Unrecognized Psychological Problems in the Elderly (UPPE)
Screening & PST-PC for UPPE in PC
Aims & Objectives Prevalence & risk factors Impact on HRQOL & consultation rates Nature of the problems Effectiveness of brief PST- PC for
elderly patients screened positive of psychological problems
1371 screened negative
482 HADS screened positive
5225 consecutive GOPC patients aged 60+
1473 refused, 1614 not eligible, 285 incomplete interviews
183 Refused RCT 299 Agreed to RCT
149 randomized to3x PST-PC 132 attended ≥1 PST-PC sessions
Blinded assessment at week 6, 12, 26 & 52; 69% completion
Blinded assessment at week 6, 12, 26 & 52; 71% completion
150 randomized to 3 x placebo 132 attended ≥1 video session
Study Instruments
Screening by Hospital Anxiety & Depression Scale (HADS): positive if anxiety score ≥3 or depression score ≥6
The MOS SF-36 Health Survey on HRQOL (PCS & MCS)
Structured Q. on monthly consultation rates, sociodemography & co-morbidity
PST-PC record form
Intervention: PST-PC
Three 3-hour training workshops for FM residents 3 structured brief PST-PC sessions (20-45 min)
Establish rapport Identify any psychiatric diagnosis Patient identifies & prioritize problems Patient to think of possible solutions for main problem Suggest more solutions List advantages and disadvantages of each solution Prioritize solutions Settle on the preferred solution: break it down into steps Patient is to work on the first step of the solution

Implications for Clinical Practice & Future Research
Need for PC-relevant diagnostic taxonomy Psychological diagnosis & treatment cannot be
separated from physical & social problems Little indications for drugs A multi-disciplinary system approach integrated
with routine PC Family interventions are needed The family doctor’s role in detection, motivation,
co-ordination & maintenance
