Patient participation: current knowledge and applicability to patient safety.

Patient participation is increasingly recognized as a key component in the redesign of health care processes and is advocated as a means to improve patient safety. The concept has been successfully applied to various areas of patient care, such as decision making and the management of chronic diseases. We review the origins of patient participation, discuss the published evidence on its efficacy, and summarize the factors influencing its implementation. Patient-related factors, such as acceptance of the new patient role, lack of medical knowledge, lack of confidence, comorbidity, and various sociodemographic parameters, all affect willingness to participate in the health care process. Among health care workers, the acceptance and promotion of patient participation are influenced by other issues, including the desire to maintain control, lack of time, personal beliefs, type of illness, and training in patient-caregiver relationships. Social status, specialty, ethnic origin, and the stakes involved also influence patient and health care worker acceptance. The London Declaration, endorsed by the World Health Organization World Alliance for Patient Safety, calls for a greater role for patients to improve the safety of health care worldwide. Patient participation in hand hygiene promotion among staff to prevent health care-associated infection is discussed as an illustrative example. A conceptual model including key factors that influence participation and invite patients to contribute to error prevention is proposed. Further research is essential to establish key determinants for the success of patient participation in reducing medical errors and in improving patient safety.

Impact of the Type of Diagnostic Assay on Clostridium difficile Infection and Complication Rates in a Mandatory Reporting Program

BACKGROUNDnMost Clostridium difficile infection (CDI) surveillance programs neither specify the diagnostic method to be used nor stratify rates accordingly. We assessed the difference in healthcare-associated CDI (HA-CDI) incidence and complication rates obtained by 2 validated diagnostic methods.nnnMETHODSnThis was a prospective cohort study of patients for whom a C. difficile test was ordered between 1 August 2010 and 31 July 2011. All specimens were tested in parallel by a commercial polymerase chain reaction (PCR) assay targeting toxin B gene tcdB, and a 3-step algorithm detecting glutamate dehydrogenase and toxins A and B by enzyme immunoassay and cell culture cytotoxicity assay (EIA/CCA). CDI incidence rate ratios were calculated using univariate Poisson regression.nnnRESULTSnA total of 1321 stool samples were tested during a period totaling 95 750 patient-days. Eighty-five HA-CDI cases were detected by PCR and 56 cases by EIA/CCA (P = .01). The overall incidence rate was 8.9 per 10 000 patient-days (95% confidence interval [CI], 7.1-10.9) by PCR and 5.8 per 10 000 patient-days (95% CI, 4.4-7.4) by EIA/CCA (P = .01). The incidence rate ratio comparing PCR and EIA/CCA was 1.52 (95% CI, 1.08-2.13; P = .015). Overall complication rate was 27% (23/85) when CDI was diagnosed by PCR and 39% (22/56) by EIA/CCA (P = .16). Cases detected by PCR only were less likely to develop a complication of CDI compared with cases detected by both PCR and EIA/CCA (3% vs 39%, respectively; P < .001).nnnCONCLUSIONSnPerforming PCR instead of EIA/CCA is associated with a >50% increase in the CDI incidence rate. Standardization of diagnostic methods may be indicated to improve interhospital comparison.

Involving the patient to ask about hospital hand hygiene: a National Patient Safety Agency feasibility study

Healthcare-associated infections (HAIs) affect at least 300,000 patients annually in the UK and represent a significant, yet largely preventable, burden to healthcare systems. Hand hygiene by healthcare workers (HCWs) is the leading prevention measure, but compliance with good practice is generally low. The UK National Patient Safety Agency surveyed the public, inpatients, and HCWs, particularly frontline clinical staff and infection control nurses, in five acute care hospitals to determine whether they agreed that a greater level of involvement and engagement with patients would contribute to increased compliance with hand hygiene and reduce HAIs. Fifty-seven percent (302/530) of the public were unlikely to question doctors on the cleanliness of their hands as they assumed that they had already cleaned them. Forty-three percent (90/210) of inpatients considered that HCWs should know to clean their hands and trusted them to do so, and 20% (42/210) would not want HCWs to think that they were questioning their professional ability to do their job correctly. Most HCWs surveyed (178/254, 71%) said that HAI could be reduced to a greater or lesser degree if patients asked HCWs if they had cleaned their hands before touching them. Inviting patients to remind HCWs about hand hygiene through the provision of individual alcohol-based hand-rub containers and actively supporting an Its OK to ask attitude were perceived as the most useful interventions by both patients and HCWs. However, further work is required to refute the myth among HCWs that patient involvement undermines the doctor- or HCW-patient relationship.

Effect of Detecting and Isolating Clostridium difficile Carriers at Hospital Admission on the Incidence of C difficile Infections: A Quasi-Experimental Controlled Study

IMPORTANCEnClostridium difficile infection (CDI) is a major cause of health care-associated infection worldwide, and new preventive strategies are urgently needed. Current control measures do not target asymptomatic carriers, despite evidence that they can contaminate the hospital environment and health care workers hands and potentially transmit C difficile to other patients.nnnOBJECTIVEnTo investigate the effect of detecting and isolating C difficile asymptomatic carriers at hospital admission on the incidence of health care-associated CDI (HA-CDI).nnnDESIGN, SETTING, AND PARTICIPANTSnWe performed a controlled quasi-experimental study between November 19, 2013, and March 7, 2015, in a Canadian acute care facility. Admission screening was conducted by detecting the tcdB gene by polymerase chain reaction on a rectal swab. Carriers were placed under contact isolation precautions during their hospitalization.nnnMAIN OUTCOMES AND MEASURESnChanges in HA-CDI incidence level and trend during the intervention period (17 periods of 4 weeks each) were compared with the preintervention control period (120 periods of 4 weeks each) by segmented regression analysis and autoregressive integrated moving average (ARIMA) modeling. Concomitant changes in the aggregated HA-CDI incidence at other institutions in Québec City, Québec (nu2009=u20096) and the province of Québec (nu2009=u200994) were also examined.nnnRESULTSnOverall, 7599 of 8218 (92.5%) eligible patients were screened, among whom 368 (4.8%) were identified as C difficile carriers. During the intervention, 38 patients (3.0 per 10u202f000 patient-days) developed an HA-CDI compared with 416 patients (6.9 per 10u202f000 patient-days) during the preintervention control period (Pu2009<u2009.001). There was no immediate change in the level of HA-CDIs on implementation (Pu2009=u2009.92), but there was a significant decrease in trend over time of 7% per 4-week period (rate ratio, 0.93; 95% CI, 0.87-0.99 per period; Pu2009=u2009.02). ARIMA modeling also detected a significant effect of the intervention, represented by a gradual progressive decrease in the HA-CDI time series by an overall magnitude of 7.2 HA-CDIs per 10u202f000 patient-days. We estimated that the intervention had prevented 63 of the 101 (62.4%) expected cases. By contrast, no significant decrease in HA-CDI rates occurred in the control groups.nnnCONCLUSIONS AND RELEVANCEnDetecting and isolating C difficile carriers was associated with a significant decrease in the incidence of HA-CDI. If confirmed in subsequent studies, this strategy could help prevent HA-CDI.

Patients’ Beliefs and Perceptions of Their Participation to Increase Healthcare Worker Compliance with Hand Hygiene

BACKGROUNDnResearch suggests that patients could improve healthcare workers compliance with hand hygiene recommendations by reminding them to cleanse their hands.nnnOBJECTIVEnTo assess patients perceptions of a patient-participation program to improve healthcare workers compliance with hand hygiene.nnnDESIGNnCross-sectional survey of patient knowledge and perceptions of healthcare-associated infections, hand hygiene, and patient participation, defined as the active involvement of patients in various aspects of their health care.nnnSETTINGnLarge Swiss teaching hospital.nnnRESULTSnOf 194 patients who participated, most responded that they would not feel comfortable asking a nurse (148 respondents [76%]) or a physician (150 [77%]) to perform hand hygiene, and 57 (29%) believed that this would help prevent healthcare-associated infections. In contrast, an explicit invitation from a healthcare worker to ask about hand hygiene doubled the intention to ask a nurse (from 34% to 83% of respondents; P < .001) and to ask a physician (from 30% to 78%; P < .001). In multivariate analysis, being nonreligious, having an expansive personality, being concerned about healthcare-associated infections, and believing that patient participation would prevent healthcare-associated infections were associated with the intention to ask a nurse or a physician to perform hand hygiene (P < .05). Being of Jewish, Eastern Orthodox, or Buddhist faith was associated also with increased intention to ask a nurse (P < .05), compared with being of Christian faith.nnnCONCLUSIONSnThis study identifies several sociodemographic characteristics associated with the intention to ask nurses and physicians about hand hygiene and underscores the importance of a direct invitation from healthcare workers to increase patient participation and foster patient empowerment. These findings could guide the development of future hand hygiene-promotion strategies.

Contamination of stethoscopes and physicians' hands after a physical examination

OBJECTIVESnTo compare the contamination level of physicians hands and stethoscopes and to explore the risk of cross-transmission of microorganisms through the use of stethoscopes.nnnPATIENTS AND METHODSnWe conducted a structured prospective study between January 1, 2009, and May 31, 2009, involving 83 inpatients at a Swiss university teaching hospital. After a standardized physical examination, 4 regions of the physicians gloved or ungloved dominant hand and 2 sections of the stethoscopes were pressed onto selective and nonselective media; 489 surfaces were sampled. Total aerobic colony counts (ACCs) and total methicillin-resistant Staphylococcus aureus (MRSA) colony-forming unit (CFU) counts were assessed.nnnRESULTSnMedian total ACCs (interquartile range) for fingertips, thenar eminence, hypothenar eminence, hand dorsum, stethoscope diaphragm, and tube were 467, 37, 34, 8, 89, and 18, respectively. The contamination level of the diaphragm was lower than the contamination level of the fingertips (P<.001) but higher than the contamination level of the thenar eminence (P=.004). The MRSA contamination level of the diaphragm was higher than the MRSA contamination level of the thenar eminence (7 CFUs/25 cm(2) vs 4 CFUs/25 cm(2); P=.004). The correlation analysis for both total ACCs and MRSA CFU counts revealed that the contamination level of the diaphragm was associated with the contamination level of the fingertips (Spearmans rank correlation coefficient, ρ=0.80; P<.001 and ρ=0.76; P<.001, respectively). Similarly, the contamination level of the stethoscope tube increased with the increase in the contamination level of the fingertips for both total ACCs and MRSA CFU counts (ρ=0.56; P<.001 and ρ=.59; P<.001, respectively).nnnCONCLUSIONnThese results suggest that the contamination level of the stethoscope is substantial after a single physical examination and comparable to the contamination of parts of the physicians dominant hand.

Patient Empowerment and Multimodal Hand Hygiene Promotion: A Win-Win Strategy:

Patient empowerment is a new concept in health care that has now been extended to the domain of patient safety. Within the framework of the development of the new World Health Organization (WHO) Guidelines on Hand Hygiene in Health Care, the authors conducted a review of the literature from 1997 to 2008 to identify the evidence supporting programs aimed at encouraging patients to take an active role in their care. Patient empowerment is an integral part of the WHO hand hygiene multimodal strategy. Hand hygiene promotion strategies that have demonstrated evidence of successfully empowering patients include one or all of the following components: educational tools, motivation and reminder tools, and role modeling. What is important is that programs and models to empower patients must be developed with an inbuilt evaluation component that includes both qualitative and quantitative measures to determine not only what works but under what conditions and within which organizational context.

Videos in clinical medicine. Hand hygiene

Hand hygiene is a procedure that should be mastered by all health care workers. Hand hygiene is not optional - it is mandatory. It must be used conscientiously to decrease the occurrence of infections associated with health care and to increase patient safety. Proper use of hand hygiene is a sign of competency, professionalism, and respect. Copyright

Seasonal Variations in Clostridium difficile Infections Are Associated with Influenza and Respiratory Syncytial Virus Activity Independently of Antibiotic Prescriptions: a Time Series Analysis in Québec, Canada

ABSTRACT Seasonal variations in Clostridium difficile-associated diarrhea (CDAD), with a higher incidence occurring during winter months, have been reported. Although winter epidemics of respiratory viruses may be temporally associated with an increase in CDAD morbidity, we hypothesized that this association is mainly due to increased antibiotic use for respiratory infections. The objective of this study was to evaluate the effect of the two most frequent respiratory viruses (influenza virus and respiratory syncytial virus [RSV]) and antibiotics prescribed for respiratory infections (fluoroquinolones and macrolides) on the CDAD incidence in hospitals in the province of Québec, Canada. A multivariable Box-Jenkins transfer function model was built to relate monthly CDAD incidence to the monthly percentage of positive tests for influenza virus and RSV and monthly fluoroquinolone and macrolide prescriptions over a 4-year period (January 2005 to December 2008). Analysis showed that temporal variations in CDAD incidence followed temporal variations for influenza virus (P = 0.043), RSV (P = 0.004), and macrolide prescription (P = 0.05) time series with an average delay of 1 month and fluoroquinolone prescription time series with an average delay of 2 months (P = 0.01). We conclude that influenza virus and RSV circulation is independently associated with CDAD incidence after controlling for fluoroquinolone and macrolide use. This association was observed at an aggregated level and may be indicative of other phenomena occurring during wintertime.

Detection and Quantification of Airborne Norovirus During Outbreaks in Healthcare Facilities

BACKGROUNDnNoroviruses are responsible for at least 50% of all gastroenteritis outbreaks worldwide. Noroviruses GII can infect humans via multiple routes including direct contact with an infected person, fecal matter, or vomitus, and contact with contaminated surfaces. Although norovirus is an intestinal pathogen, aerosols could, if inhaled, settle in the pharynx and later be swallowed. The aims of this study were to investigate the presence of norovirus GII bioaerosols during gastroenteritis outbreaks in healthcare facilities and to study the in vitro effects of aerosolization and air sampling on the noroviruses using murine norovirus as a surrogate.nnnMETHODSnA total of 48 air samples were collected during norovirus outbreaks in 8 healthcare facilities. Samples were taken 1 m away from each patient, in front of the patients room and at the nurses station. The resistance to aerosolization stress of murine norovirus type 1 (MNV-1) bioaerosols was also tested in vitro using an aerosol chamber.nnnRESULTSnNorovirus genomes were detected in 6 of 8 healthcare centers. The concentrations ranged from 1.35 × 10(1) to 2.35 × 10(3) genomes/m(3) in 47% of air samples. MNV-1 preserved its infectivity and integrity during in vitro aerosol studies.nnnCONCLUSIONSnNorovirus genomes are frequently detected in the air of healthcare facilities during outbreaks, even outside patients rooms. In addition, in vitro models suggest that this virus may withstand aerosolization.
