1.11 Transfer & Positioning Safety for Oncology Patients
Key Takeaways
- Proper body mechanics require maintaining a wide base of support (feet shoulder-width apart) and bending at the knees/hips, NOT at the waist.
- Urinary drainage bags MUST be kept suspended BELOW the level of the patient's bladder at all times to prevent retrograding urine and CAUTI.
- Intravenous (IV) fluid bags must remain 18 to 24 inches above the injection site/heart level to maintain gravity flow and prevent line occlusion.
- Transferring a patient from a stretcher to a treatment couch requires locking all wheels and utilizing a minimum of 2 to 3 personnel with a slide board.
- Chest drainage units must remain upright and strictly BELOW chest level; chest tubes should NEVER be clamped without an explicit physician order.
1.11 Transfer & Positioning Safety for Oncology Patients
Radiation therapists perform multiple patient transfers and positioning maneuvers throughout each clinical shift. Oncology patients present unique safety challenges during transfer and positioning due to cancer cachexia, muscle atrophy, pathological fracture risks from osteolytic bone metastases, acute spinal cord compression risks, severe fatigue, orthostatic hypotension, and the presence of indwelling medical lines (IV lines, urinary catheters, chest tubes). Adhering to ergonomic body mechanics, structured transfer protocols, and oncology-specific clinical precautions protects both patients and radiation therapy staff from severe injury.
Principles of Ergonomics & Body Mechanics
Work-related musculoskeletal disorders (MSDs)—particularly lumbar spine disc herniation and strain—represent a major occupational hazard for radiation therapists. Applying ergonomic principles minimizes spinal shear stress and spinal compressive loads:
+-------------------------------------------------------------------------+
| RULES OF SAFE BODY MECHANICS |
+-------------------------------------------------------------------------+
| 1. BASE OF SUPPORT: Stand with feet shoulder-width apart, one foot |
| slightly forward for optimal balance. |
| 2. CENTER OF GRAVITY: Keep heavy loads as close to your pelvis/body |
| center of gravity as possible. |
| 3. BEND AT KNEES & HIPS: Maintain neutral spinal alignment. Never bend |
| forward at the waist during a lift! |
| 4. PUSH RATHER THAN LIFT: Pushing or rolling utilizes body weight and |
| imposes significantly less spinal load. |
| 5. AVOID AXIAL TWISTING: Pivot with your feet to change direction; |
| never twist your torso while supporting weight.|
| 6. USE POWER MUSCLE GROUPS: Lift using quadriceps and gluteals rather |
| than weak lumbar erector spinae muscles. |

Pre-Transfer Patient Assessment
Before initiating any patient transfer onto or off the treatment couch, the radiation therapist must complete a comprehensive functional and clinical evaluation:
- Weight-Bearing Capacity & Balance: Determine whether the patient can perform a standing pivot transfer independently, requires 1-person or 2-person assistance, or requires a mechanical lift or transfer board.
- Pathological Fracture Risk: Evaluate whether the patient has known osteolytic bone metastases involving the pelvis, femur, or spine. Forced movements or improper leverage can cause catastrophic iatrogenic fractures.
- Cognitive & Neurological Status: Assess for confusion, brain metastases, ataxia, or motor deficits that impair the patient's ability to follow transfer commands.
- Medical Line Inventory: Locate and trace all intravenous lines, urinary catheters, chest drainage tubes, oxygen tubing, and feeding tubes prior to initiating movement.
- Fall Risk Screening: Utilize standardized screening tools such as the Morse Fall Scale or Hendrich II Fall Risk Model.
Transfer Techniques & Protocols
1. Wheelchair-to-Couch Transfers (2-Person / 1-Person Assist)
- Positioning: Position the wheelchair at a 45-degree angle to the treatment couch, placing the patient's stronger (unaffected) side closest to the table.
- LOCK WHEELS: Lock both wheelchair brakes securely.
- Footrests: Flip up or swing away both footrests completely. Never allow a patient to step on wheelchair footrests during a transfer, as this causes the wheelchair to tip forward.
- Gait Belt Application: Apply a heavy-duty gait belt securely around the patient's waist over clothing.
- Execution: Therapists flex their knees, maintain a wide base of support, and grasp the gait belt. Instruct the patient to push off the wheelchair armrests (never grab the therapist's neck). Pivot the patient smoothly and lower them safely onto the treatment couch.
2. Stretcher (Gurney)-to-Couch Transfers
- Brake Locking & Height Alignment: Lock both stretcher and treatment couch brakes firmly. Adjust stretcher height so it is level with or slightly higher than the treatment couch.
- Staffing Requirements: Minimum of 2 to 3 healthcare personnel (4 personnel for heavy, sedated, or hemodynamically unstable patients).
- Transfer Devices: Utilize friction-reducing transfer aids, specifically a slide board (transfer board) or a heavy-duty drawsheet.
- Coordination: The lead therapist stands at the head of the couch holding the patient's head and neck alignment, directing the move on a synchronized count ("1, 2, 3, slide").
+-------------------------------------------------------------------------+
| SLIDE BOARD (TRANSFER BOARD) STEPS |
+-------------------------------------------------------------------------+
| 1. Log-roll patient slightly away from the treatment couch. |
| 2. Insert slide board under the drawsheet beneath the patient. |
| 3. Return patient to supine position resting on the slide board. |
| 4. Have patient cross arms across chest. |
| 5. Synchronized pull on drawsheet across the slide board onto couch. |
| 6. Log-roll patient to remove slide board immediately after transfer. |
+-------------------------------------------------------------------------+
Safe Management of Medical Lines & Drainage Devices
Careless handling during transfer can cause accidental line dislodgement, severe tissue trauma, hemorrhage, or life-threatening complications.
+-------------------------------------------------------------------------+
| MEDICAL LINE MANAGEMENT RULES |
+-------------------------------------------------------------------------+
| INTRAVENOUS (IV) LINES & INFUSION PUMPS |
| - Maintain IV fluid bag 18 to 24 inches ABOVE injection site / heart. |
| - Prevents blood backflow into tubing and preserves infusion rate. |
| - Protect lines from catching on treatment couch rails or accessories. |
+-------------------------------------------------------------------------+
| FOLEY URINARY CATHETERS |
| - Keep drainage bag suspended strictly BELOW bladder level at all times!|
| - NEVER place urinary drainage bag on patient abdomen or table surface!|
| - Prevents retrograde flow of urine and Catheter-Associated UTIs. |
+-------------------------------------------------------------------------+
| CHEST TUBES (Pleural Drainage Units) |
| - Keep chest drainage unit upright and strictly BELOW chest level. |
| - NEVER CLAMP a chest tube without an explicit physician order! |
| - Clamping causes rapid accumulation of air/fluid and tension |
| pneumothorax, leading to cardiovascular collapse and fatality! |
+-------------------------------------------------------------------------+
Special Oncology Precautions: Cord Compression & Pathological Fractures
1. Spinal Cord Compression (MSCC) Precautions
Metastatic Spinal Cord Compression (MSCC) is an oncological emergency occurring when tumor erodes into the epidural space, compressing the spinal cord.
- Precautions during Transfer & Positioning: Patients with suspected or confirmed spinal cord compression must be transferred using strict spinal immobilization protocols.
- Log-Roll Technique: Utilize a minimum 3-person log-roll technique, maintaining the head, neck, thoracic, and lumbar spine in a rigid, straight line without twisting or axial flexion.
- Positioning on Treatment Table: Avoid any spinal hyper-flexion or extension. Ensure full spinal support with rigid positioning boards and vacuum immobilization cushions (Vac-Lok).
2. Pathological Fracture Precautions
Patients with osteolytic bone metastases (commonly secondary to breast, lung, prostate, renal cell, or myeloma malignancies) suffer from extreme cortical bone thinning.
- Precautions: Never apply torsional force, traction, or sudden jerking motions to limbs during transfer or positioning.
- Support: Support limbs above and below joint structures simultaneously during movement. Avoid localized point-pressure loads on vulnerable skeletal regions.
3. Positioning Safety, Fall Prevention & Skin Integrity
- Treatment Couch Risks: Radiation treatment couches are narrow, hard, unpadded, and elevated 3 to 4 feet off the floor.
- NEVER Leave Patients Unattended: Never leave an elderly, confused, sedated, pediatric, or neurologically impaired patient unattended on an elevated treatment couch for any duration.
- Epidermal Shear Prevention: Irradiated skin undergoes epidermal thinning and basal layer depletion. Dragging a patient across table linen causes epidermal shear tears. Therapists must use a "lift-and-place" technique or low-friction transfer sheets rather than sliding friction to protect fragile irradiated skin.
