Aspiration and Choking Expert Witness

Choking and aspiration get grouped together, but they're different injuries that lead to different cases.

Choking is an acute airway obstruction. A piece of food blocks the airway, the person can't breathe, and the outcome is decided in minutes. These cases center on what the resident was served, who was watching, and how staff responded.

Aspiration is food, liquid, saliva, or stomach contents entering the lungs. It may cause immediate coughing and distress, but often it's silent. The harm usually shows up days later as aspiration pneumonia. These cases center on whether the swallowing risk was identified and managed, and whether the pneumonia was recognized in time.

Both are common in nursing homes, assisted living, group homes for people with developmental disabilities, and hospitals. Both are frequently preventable. The patients at highest risk are well known: people with dementia, stroke, Parkinson's disease, ALS, head and neck cancer, developmental disabilities, and anyone on sedating medications.

Before the meal: identifying the risk

Every case starts with what the facility knew about the person's swallowing.

A reasonable facility screens for swallowing problems on admission and after any change in condition, including a stroke, a hospitalization, a new sedating medication, coughing at meals, or weight loss. A positive screen should lead to a referral to a speech-language pathologist for a swallowing evaluation. Sometimes that means an instrumental study, like a modified barium swallow or a fiberoptic endoscopic evaluation, which can detect silent aspiration that a bedside exam misses.

The SLP's recommendations become the plan. They typically specify:

• The diet texture and liquid consistency
• Positioning during and after meals
• Supervision level, from independent to one-on-one assistance
• Specific strategies like small bites, chin tuck, alternating solids and liquids, or pacing
• Whether the person can feed themselves

Many facilities now use the International Dysphagia Diet Standardisation Initiative (IDDSI) framework, which defines texture levels for foods and drinks. Older records may use the National Dysphagia Diet categories instead. The expert should be comfortable with both.

At the table: where most cases happen

The breach in most choking cases happens during the meal itself. Recurring facts include:

• Wrong texture. A resident on a pureed or minced and moist diet gets a regular tray, or a sandwich, or a whole hot dog. Tray tickets, kitchen production records, and diet orders often show where the mistake happened.
• Thin liquids given to someone ordered thickened liquids. Common at bedside, during medication passes, and with drinks left within reach.
• Inadequate supervision. A resident who requires one-on-one assistance left alone with food, or a dining room with too few staff to watch everyone at risk.
• Food from other sources. A resident with dementia takes food from another resident's tray, or family brings in food that doesn't match the diet order, with no education or oversight.
• Positioning failures. Residents fed while reclined in bed, or laid flat right after eating.
• Rushed feeding. Staff feeding too fast or giving large spoonfuls to get through a dining room on a tight schedule.

When it happens: the emergency response

In choking cases, the response is often as important as the cause. Staff should recognize choking immediately, call for help, and perform abdominal thrusts or other appropriate airway clearance, then start CPR if the person becomes unresponsive. Delays, untrained staff, missing suction equipment, and confusion about code status all come up.

DNR orders are a frequent source of confusion. A do-not-resuscitate order generally applies to cardiopulmonary arrest, not to clearing an obstructed airway. Staff who withhold the Heimlich maneuver because a resident has a DNR have usually misunderstood the order, and facilities are expected to train staff on this distinction.

After the event: recognizing aspiration pneumonia

When aspiration is suspected, or a resident shows new fever, cough, faster breathing, lower oxygen levels, or new confusion, the standard is prompt assessment and physician notification. That's followed by chest imaging, antibiotics, and possibly hospital transfer. Aspiration pneumonia that progresses to sepsis or respiratory failure over several days while nursing notes document worsening symptoms is a common fact pattern.

Feeding tubes don't eliminate the risk. Tube-fed patients aspirate stomach contents, especially when the head of the bed isn't kept elevated during and after feedings, or when residual volumes and tolerance aren't monitored.

Experts these cases need

A speech-language pathologist with dysphagia experience in the relevant setting is usually central. The SLP addresses evaluation, diet recommendations, and whether the plan was followed. A long-term care nurse covers supervision, diet order implementation, positioning, emergency response, and change-of-condition monitoring. A registered dietitian or food service expert can trace a diet order through the kitchen when the wrong texture was served. Physicians, typically geriatrics, pulmonology, or infectious disease, address aspiration pneumonia and causation. In fatal choking cases, a forensic pathologist interprets autopsy findings, including whether a food bolus was found in the airway and how it compares to the resident's ordered diet.

In facilities for people with developmental disabilities, look for experts with experience in that setting. Mealtime protocols there are often more detailed and individually specific than in nursing homes. See also when your case needs two expert witnesses.

Records to collect

SLP evaluations and any instrumental swallow studies, diet orders and every change, tray tickets and menus, kitchen production and texture modification records, meal assistance and intake logs, care plans, staffing and dining room assignments, incident reports, code records, EMS reports, hospital records, and autopsy findings. Witness statements from dining staff and other residents' family members can fill in what the documentation leaves out.

Common questions

Is aspiration pneumonia always preventable?

No. Some high-risk patients aspirate despite good care. The question is whether the risk was evaluated, the recommendations were followed, and the pneumonia was caught and treated promptly.

Does a DNR mean staff shouldn't intervene in a choking event?

Generally no. Clearing an airway obstruction is usually treated differently from resuscitation after cardiac arrest, though the specific order and state law should be reviewed.

Who proves the wrong food was served?

Often a combination of the autopsy, the tray ticket, the kitchen's production records, and staff testimony. A food service or dietitian expert can explain how the system was supposed to work.
