Counting of accountable items

Chan Suk Ming, Maria

APN, Operating Theatre Queen Elizabeth Hospital

Objectives •  To explore the importance of counting.

•  To identify the risk and impact of retained foreign bodies in patients’ bodies after operation.

•  To explore the legal liability of OT personnel after the critical incident.

•  To learn the “Principle of Counting” •  To identify ways to reduce risk.

Why count?

“COUNTS  are  performed  to  account  for  items  …  

     ensure  that  the  pa9ent  is  not  injured  as  a  result  of  a  retained  foreign  body”

AORN Recommended Practices for Sponges,

Sharps and Instrument count

What are the accountable items during operation?

Anything that is opened onto the sterile field are known as “accountable items”

1. Sponge

(Raytec gauze, dental swabs and patties) 2. Sharps (Suture, needles, blades, needles,

trocar, diathermy pen tips)

3. Instruments (all kinds of instruments including the screws, coating)

4. Miscellaneous items (cotton tapes, surgiloops, cautery pads

etc.)

• When accountable items are not counted and documented à a potential risk of retained foreign body.

• To prevent this problem: : Counting policy must be reviewed and revised.

What is foreign body?

• Anything that does not naturally belong to one’s own body.

•  Introduced from outside intentionally or

accidentally

Foreign bodies intentionally left with patient

•  Implants • Sutures • Auto-sutures • Allograft • Surgicel/Gelfoam • Gauze/Swab

Foreign bodies accidentally left with our patients

•  Gauze/swab •  Instrument/Missing parts of an instrument/screw •  Broken Drill Bit •  Broken wire •  Diathermy tip and tip cleanser •  Surgiloop •  Gloves

The most common surgically retained foreign body is ?????

According to the research done by the ECRI Institute • Retained foreign objects (RFOs) in surgical

patients show that à sponges are the items most frequently reported as retained à followed by instruments

3

Accuracy of the count affected by: • The complexity of the surgery

• The urgency of the surgery • The surgical team’s fatigue (duration and

late-day procedures)

Human Factors in the Counting Process

• Communication failures • Distractions from multiple competing

interests • Pressure for increased productivity • Lack of sufficient personnel

Case Study Removal of PICC • PICC placed at a

hospital. • On its removal, the

catheter was broken and missing.

• Where had it gone????

• This catheter fragment had embolized 栓塞 to the left pulmonary artery

Migration of the catheter fragments

• Along the blood stream finally lodging in either:

: Vena cava : Right atrium : Right ventricle : Pulmonary artery

Serious complications:

• Myocardial perforation ⼼心肌穿孔 • Myocardial infarction ⼼心肌梗死 • Valvular perforation 瓣膜穿孔 • Arrhythmia ⼼心律失常 • Cardiac arrest ⼼心臟驟停 • Endocarditis ⼼心內膜炎 • Pulmonary abscess肺膿腫

Thoracotomy

•  In 2003 Europe • TSSU staff reported à rib approximator à screw missing

• X-Ray taken in the RR and the screw was found in patient’s chest

• Patient was sent back to theatre for re-operation.

• This case highlights the importance of : checking the small connections of the instrument : especially if an instrument become loose.

Possible risks that could happen after the critical incident

• Re-operation • Perforation of internal organs • Sepsis or infection • Readmission or prolonged hospital stay • Death

Legal aspects 法律標準

• Washington - since 1929: “When a surgeon inadvertently leaves a foreign substance in the body with no possibility of any therapeutic purpose, the act constitutes negligence 疏忽”

Case study

•  “In Van Hook, the hospital had a policy that required the nurses to account for all swabs.

• The nurse had told the surgeon the swabs

had been all accounted for when, in fact, they had not.

5

•  The Van Hook court held the surgeon not liable because the swab count was the nurses’ responsibility.”

•  “In many states, a retained foreign body will be considered negligence per se.”

•  “When cases are avoidable and cause injuries to our clients, many lead to mal-practice claims索賠”

Legal aspect

“The law does not require that objects in the surgical field be counted – only that nothing inadvertently be left within the wound.”

Canadian Journal of Surgery 2004

• The Canadian Association of General Surgeons initiated a program called “Evidence Based Reviews in Surgery”.

• Setting: A malpractice insurance agency and 10 hospitals in the state of Massachusetts from January, 1985 to January, 2001.

• The study includes 54 patients with a total of 61 retained foreign bodies

Risk factors identified

• Lack of a complete count of swabs , needles and instruments

• Change in nursing personnel during surgery

• Fatigue in the surgical team

• Talking, talking and talking

• Obesity of the patient

• Urgency of the surgery

• Excessive loss of blood

7

• An unexpected change in a procedure

• The involvement of multiple

surgical teams

Preventive measures for retained gauze in patients’ bodies 1. Use Raytec gauze for all procedures no matter

how minor or how superficial the wound is.

2. Non-radio-opaque swabs should not be available to the surgical team until the wound is closed.

3. No radio-opaque gauze should be used for dressing

4. Raytec gauze should never be cut into pieces

5. Record all gauzes opened onto the sterile field

6. Gauze must placed within the operating room until all counts completed

7. Check that swabs from the previous operations have been removed

8. Take special care during major, multiple operations

9. When surgeon packs a gauze in a cavity, record it on the whiteboard/count sheet.

10. ↓ Change of OT personnel during operation.

11. Hand over à a full swab and instrument

check

8

12. Surgeon should allow sufficient time for checking upon closure.

13. Scrub personnel should report the count result to the surgeon.

14. Scrub personnel should inform the surgeon of any discrepancy

15. Count gauzes according to standard

and guidelines.

Principle of Counting

1. Count all accountable items that possesses the likelihood to be retained in patient’s body

Principle of Counting

2. Two personnel – one must be Registered Nurse:

: View concurrently : Count audibly : Same sequence

Principle of Counting

3. Maintain concurrent information for all accountable items throughout the operative procedure

4. Perform counts for all accountable items before the procedure to establish a baseline for subsequent counts

Principle of Counting

5. Perform counts when additional accountable items are added to the sterile field. 6. Perform counts for all accountable items prior to closure of a cavity within a cavity 7. Perform counts for all accountable items before wound closure begins

9

Principle of Counting

8. Perform counts for all accountable items at skin closure or the end of the operative procedure(s). 9. Adopt progressive counting away technique throughout the operating procedure

Progressive counting away technique

•  Should be performed and documented by circulating person, witnessed by the scrub person, one of whom should be RN.

•  All gauze and swabs should be counted away in

multiple of 5 or 10, or as per original packaging. •  All counted away items should be kept in an

isolated and sealed receptacle.

Principle of Counting

10. Confine all accountable items, including all counted away items, in the operating room until after completion of the operative procedure.

11. Check all accountable items for entirety throughout the operative procedure.

Principle of Counting

12. Confirm with the surgeon concerning the status of the count at closure of each body cavity and at the end of the operative procedure.

13. Perform counts for all accountable items at the relief of the scrub person.

Principle of Counting 14. Initiate appropriate actions when discrepancy of counts occurs. 15. Maintain an accurate documentation of the count result. 16. Document the retention of accountable items intentionally left in patient’s cavity

Counting of instrument •  Instrument check lists

should be available • Should be used to

check the instruments at the beginning and end of every case.

10

•  Instruments with screws, removable parts must be checked.

•  Instruments should be counted before they are separated and set up on a mayo table

• Any damaged instruments or not working properly à must be removed and labeled for repair

• Staff involved in counting à must be able to recognize the instruments they are counting.

•  If an instrument tray is incorrect during the initial count à

Ø it should be either be removed and a new one opened or

Ø continue to be used if the scrub person is satisfied that the instrumentation required for the procedure is present.

• However, in both circumstances, the missing instrument must be : documented on the instrument check list : TSSU informed.

•  If the returned instrument is not complete: à inform NO I/C à notify the surgeon to search the wound. à scrub personnel searches the sterile field and circulating searches the floor, linen and garbage bags.

11

•  If the missing parts of the instrument cannot be found, check with X-Ray.

• Whenever the patient has got an unnecessary X-Ray à no matter the missing parts can or cannot be found, document in the Nursing Record.

Progressive Counting away of instrument • Can be done to assist in the management

of large numbers of instruments. • Must be counted by the two personnel,

one must be RN and removed from the sterile field.

•  Hospital should clearly define circumstances in which the instrument count may be waived.

ü Complex procedures with large numbers of instruments ü Trauma ü Procedures require complex instruments with numerous

small parts ü Procedures where the width and depth of the incision is

too small to retain an instrument

Preventive measures to prevent sharps/instruments retained in patients’ bodies

• Sharps like needles and blades used by surgeon should be counted and recorded, no matter how minor or superficial wound is.

• Check each sharps after use to ensure that they are complete.

• When powered tools are used, check that

attachments, saws, blades, burrs, drill bits are complete after use.

• When using Laparoscopic instruments à check the instrument screws and coating upon return by surgeons.

12

• Maintenance of instrument should be done regularly : Screws tightened : Joints lubricated : Osteotomes/Chisels sharpened : Powered instruments lubricated : Blunt drill bits/tap replaced : Scissors sharpened

• Care should be taken not to cut cotton tapes, surgiloops

• Cotton tapes, surgiloops and patties used on the operative site should all be counted.

Steps to follow when there is a “Count discrepancy”

• Recount •  Inform NO I/C, room I/C, circulating nurse

and surgeons.

• Conduct search: : Surgeon searches the operative field : Scrub person search the sterile field

• Circulating nurse search Ø linen Ø garbage bags Ø under bed and tables Ø rest of the theatre

• Recount •  If not found, check

with X-Ray

13

Count Results

•  If correct: Document on intra-operative record

If incorrect after search

• Check X-Ray: • Document on intra-operative record • Report incident in AIRS (Advanced

Incident Reporting System)

Sharps: Needles, blades, drill bits…

• Sharps broken during a procedure must be accounted for their entirety.

•  If the sharps are broken and are not completed during the procedure:

à notify surgeons and NO IC. à If the surgeon determined not to remove the broken parts à Documentation

How to record broken instruments left within patients’ body?

à Record the nature of the broken instrument à Record the size of the broken instrument à Record the name of the surgeon who decided

to leave the broken parts within patients’ body à Record the name of the NO IC who you have

reported the incident

Risk Reduction Strategies

• Counting alone may not prevent postoperative retention of a foreign object.

• Routine X-ray screening • Assistive Technology

14

Postoperative X-ray screening • Stainless steel instruments are likely to be

detected • X-ray is less sensitive in detecting sponges

and needles • Sponges may twisted or folded, or a non

-radio-opague sponge being used • Needles may be difficult to visualize due to

their size

Assistive Technology

• Radio-frequency (RF) detectable sponge systems

• Bar-coded sponge systems

Radio-frequency (RF) detectable sponge systems Bar-coded sponge systems

• These aids are used in addition to the manual count, not replace it.

• X-ray is not always effective in identifying retained foreign bodies.

•  In one study, 67% of intraoperative X-ray were read as negative when a retained foreign body was actually present.
