C. difficile control: Handwashing practices lax at Quebec hospitals

An Enqute investigation finds that more than a decade after Quebec first faced a deadly outbreak of Clostridium difficile most health-care workers in Quebec hospitals still get a failing grade when it comes to the basic preventative act of handwashing.

Radio-Canada's Enqute exposes abysmal handwashing rates by health care workers, despite infection risks

Radio-Canada's Enqute finds average rate of handwashing by health care workers before patient contact was 42%

Handwashing is one of the most important measures health care workers can take to prevent the spread of hospital-acquired infections.

Yet more than a decade after Quebec first faced an outbreak of Clostridiumdifficileso deadly and so rampant thatit killed an estimated 1,900 people by late 2006most hospitals in Quebec still get a failing grade when it comes to that basic act of handwashing.

These premises should be zero risk,- Patient rights' advocate Paul Brunet

A six-monthinvestigation by Radio-Canada'sEnqutehas found few hospitals where doctors and other health care personnel consistently wash their hands before and after making contact with a patient.

That handwashing target isset at 80 per cent in Quebec's five-year ministerial action plan for 2015-2020 to prevent and control hospital-acquired infections.

Quebec patient rights' advocate Paul Brunet said there is no reason hospital staff aren't washing their hands 100 per cent of the time, before and after meeting each patient.

"These premises should be a zero risk," said Brunet.

However,Enqute found that the average rate of handwashingby health care workersbefore they came into contact with a patient was just over 42 per cent. After patient contact, that rate was 62 per cent.

Only 15 hospitals meet targets

Using data collected from access-to-information requests,Enqutecompiled the results of handwashingaudits supplied by 95 hospitals and other health care institutions across the province.

  • In only three hospitals did the audits show health care personnel are meeting or surpassing that 80 per cent target for handwashing before coming in contact with a patient.
  • In only a dozen institutionsdid health care personnel meet or surpass that 80 per cent target for handwashing after a patient was seen.



Key handwashing moments

Infection-control literature describes four key moments when health care staff must wash their hands:

  1. Before coming into contact with the patient or their environment
  2. Before procedures requiring sterilization
  3. After any possible contact with body fluids
  4. After contact with the patient or his environment

Most hospitalsverify compliance with all four stages, but they focus most intensely on checking the first and last steps: handwashingbefore and after contact with patients.

Even after removing gloves, health care workers are supposed to wash their hands.


C. difficile: down but not out

Quebec hospitals have conducted repeated awareness campaigns about the importance of handwashingin the years since the 2004 outbreak ofC.difficileforced them to take a hard look at infection control.
The virulent C. difficile bacteria that killed thousands of Quebec hospital patients beginning in late 2003 became known internationally as the "Quebec strain." (Centres for Disease Control and Prevention)

At least partly as a result of those campaigns, the rate of C. difficile-associated diarrhea has been on decline,hitting its lowest rate in five years in 2014-2015.

Even at that, 3,453 cases were reported in 2014-2015.

Of those cases, 547 people died within 30 days of being diagnosed with a C. difficile infection, although thebacterial infection wasn't necessarily the cause of death in every case.

C. difficile rates in Quebec, 2004-2015

Note:Data fromApril 1toMarch 31, except for 2004-2005: At that time, data was compiled from August to August. 4,315 represents the number of cases from August 2004 to March 2005. It should be noted that the total number of cases in the 12-month period from August 2004 - August 2005 was 6,350.As for death rates,data was only reported starting in August 2008.

Single-bed hospital rooms a key goal

In its five-yearaction plan to control hospital-acquired infections, the government outlines several key targets.

One of them is to eliminate hospital rooms with more than two beds and a shared washroom.

In Quebec, 29.6 per centof acute-care beds are in single rooms.

Nearly half of all hospital rooms are double occupancy.

The other 20.5 per cent of acute-care beds are in multi-bed wards.

These statistics date from September 2014 and do not take into account the MUHC's recent move to the new Glen campus, where all patients now have single rooms.)


Notes on the methodology of the Enqute investigation:

  • The red reference line in our graph is set at 80 per cent: That is the target rate for handwashing before and after patient care, set out in the five-year ministerial action plan to control hospital-acquired infections.
  • Access-to-information requests were sent in April 2015 to the 95 health-care institutions which report annually to the INSPQtheirdiarrhea rates associated withC. difficile.
  • Due to health-care system restructuring that went into effecton April 1, 2015,a secondset of access-to-information requestswere made to certain of the newCISSS and CIUSSS, in order to ensure requests all went to the competent authorities.
  • Enqute requested documents and minutes of discussionsrelating to handwashingaudits from 2010 to June 2015. Audits conducted after June 2015 were not included in these findings.
  • Hospitals did not compile observed handwashing "moments" in a single,consistent way. These differences are noted in the table.
  • Enqute didn't have access to the methodology for each handwashing audit. Experts noted some audits were conducted secretly, so that health-care personnel didn't know they were being observed. Others were more open in their approach. These differences could skew the results.
  • The sampling size of audits also varied widely: some were based on fewer than 100 observed handwashing "moments", others on thousands, observed over a longer period of time. This, too, has been noted in the tables.
  • The number of wards audited varied greatly from one hospital to another.
  • Close to a dozen hospitals undertook no handwashing audits for two or three years. Other hospitals consistently produce audit results every two months.
  • Not all hospitals audit all staff. For example, the Montreal Cardiological Institute only provided data for its audit of nurses and nursing aides. Some hospitals included patients' visitors in their audits.
  • Eight hospitals (listed below) only provided an overall average of handwashing compliance, without breaking down the practice into before-patient-contact and after-patient-contact "moments":
    • Royal Victoria Hospital (MUHC)
    • Montreal General Hospital (MUHC)
    • Montreal Chest Institute (MUHC)
    • Montreal Neurological Hospital (MUHC)
    • Maniwaki Hospital
    • Notre-Dame-du-LacHospital
    • Centre hospitalier du Pontiac
    • St-JrmeRegional Hospital
  • Based on the data provided, Enqutecould not produce a precise result for Lachine Hospital (MUHC).
  • Based on 86 of the 95 hospitals which provided data for before-patient-contact and after-patient-contact handwashing, Enqutecalculated a provincial average.

A word of warning, however: The average does not take into consideration the sampling size of each handwashing audit, so that it gives equal weight to a hospital which based its audit on a few dozen observations and one which based its audit on thousands of observations.
