What clinical parameters indicate that antihypertensive medication should be held in a long‑term care resident?

Parameters to Hold BP Medications in Long-Term Care Residents

Hold antihypertensive medications when systolic blood pressure falls below 120 mmHg in long-term care residents, particularly in those who are frail or over 80 years old.

Primary Holding Parameters

Absolute Blood Pressure Thresholds

• Systolic BP < 120 mmHg: This is the critical threshold where antihypertensive medications should be held or reduced 1
• Systolic BP < 130 mmHg with frailty: Consider holding or reducing medications, especially if the resident is on multiple agents 2, 3

The 2020 ISH guidelines explicitly state to "individualize for elderly based on frailty" with target BP of 140/90 mmHg for frail patients 1. The recent RETREAT-FRAIL trial (2025) demonstrated that reducing antihypertensive treatment in nursing home residents over 80 years with systolic BP < 130 mmHg was safe and did not increase mortality 2.

Clinical Signs of Hypotension

Hold medications immediately if the resident exhibits:

• Symptomatic hypotension: Dizziness, lightheadedness, syncope, or falls
• Orthostatic hypotension: Drop of ≥20 mmHg systolic or ≥10 mmHg diastolic upon standing
• Altered mental status or confusion related to low BP
• Acute kidney injury or worsening renal function

Frailty-Based Decision Algorithm

For Residents Over 80 Years or Frail:

1. If SBP consistently < 120 mmHg: Hold at least one antihypertensive agent
2. If SBP 120-130 mmHg on ≥2 medications: Consider reducing to monotherapy
3. If SBP 130-140 mmHg: Continue current regimen but monitor closely
4. Target range: 140-150 mmHg is acceptable 4, 3

The Canadian Hypertension Education Program (2016) specifically notes "caution should be exercised in elderly patients who are frail" 5.

Medication-Specific Considerations

High-Risk Situations Requiring Immediate Hold:

• Diuretics during acute illness: Hold during episodes of vomiting, diarrhea, or reduced oral intake due to dehydration risk
• ACE inhibitors/ARBs with acute kidney injury: Hold if creatinine rises >30% from baseline
• Multiple agents (≥3 drugs): If BP < 130 mmHg, initiate stepwise reduction 2

Research shows 40.7% of nursing home residents receive ≥3 antihypertensive drugs, with 33.9% having SBP < 120 mmHg, indicating significant overtreatment 4.

Monitoring Protocol After Holding

• Recheck BP within 24-48 hours after holding medication
• Monitor for rebound hypertension: If SBP rises above 160 mmHg, consider restarting at lower dose
• Assess functional status: Falls, cognition, and activities of daily living
• Review every 2 weeks until stable pattern established 6

Common Pitfalls to Avoid

Do not continue aggressive BP lowering in frail elderly simply because guidelines suggest lower targets for community-dwelling adults. The 2017 ACC/AHA guidelines recommend 130 mmHg threshold for non-institutionalized adults but explicitly state treatment should be individualized for those with advanced frailty 7.

Do not restart medications reflexively if BP rises to 140-150 mmHg range in frail residents over 80 years—this is an acceptable target 1, 3.

Do not hold all medications simultaneously in residents on multiple agents. The RETREAT-FRAIL trial used protocol-driven stepwise reduction, decreasing from mean 2.6 to 1.5 medications over time 2.

Quality of Life Priority

The Japanese consensus statement (2026) emphasizes prioritizing quality of life over strict BP targets in nursing care-dependent older adults, specifically recommending avoidance of SBP < 120 mmHg 3. This aligns with evidence showing that 41% of long-term care residents had all BP readings < 140/90 mmHg, suggesting potential for safe medication reduction 8.

Key principle: In long-term care, preventing hypotension-related falls and maintaining functional status takes precedence over achieving aggressive BP targets that benefit younger, community-dwelling populations.
