Hand hygiene in routine glaucoma clinics

Hand hygiene and instrument sanitization in ophthalmology clinics

PURPOSE OF REVIEW

This article reviews the various challenges in infection control in eye clinics and successful measures taken to prevent nosocomial infections.

RECENT FINDINGS

The Center for Disease Control recommends hand-washing when hands are visibly soiled, and after direct contact with patients, and inanimate objects such as medical equipment. Published studies have identified poor hygiene in clinical settings as a major cause of nosocomial outbreaks, particularly in cases of epidemic keratoconjunctivitis (EKC). Some studies of EKC outbreaks are able to support direct observation of hygiene lapses with molecular analysis that can match viral strains on particular instruments to those found in infected patients. Although most studies are about adenoviral infection and tonometer use, researchers have found viral and bacterial loads on other common surfaces, indicating a need for further research.

SUMMARY

Proper hygiene in eye clinics requires special attention because of the potential to examine many patients at a time and because multiple instruments are often used during a single exam. Studies reinforce the link between hygiene and outbreak prevention, and more research can be done to determine the specific links between certain instruments and nosocomial infections.

Raising awareness of hand-arm vibration syndrome (HAVS) using posters

BACKGROUND

Hand-arm vibration syndrome (HAVS) is caused by prolonged occupational exposure to hand-transmitted vibration. Although HAVS is preventable, disease awareness and prevention knowledge are lacking in high-risk workplaces; this may contribute to under-diagnosis, delays in seeking care, and poor health outcomes. Posters may be used to increase awareness in the workplace.

OBJECTIVE

To conduct a pilot survey in workers with HAVS about poster use in their workplaces, their recommendations for poster campaigns and training programs, and their evaluation of HAVS awareness and prevention posters.

METHODS

All eligible HAVS patients in the Occupational Health Clinic at St. Michael's Hospital, in Toronto, Canada, were asked to complete a questionnaire on workplace poster use and to evaluate a set of HAVS posters.

RESULTS

Fifty workers participated; almost all were males, aged 50 and older, working in construction. Most indicated having non-HAVS specific awareness posters in their workplaces. There was a positive evaluation of the design, content, and potential usefulness of the posters. The poster depicting finger blanching stood out most. The poster depicting anti-vibration gloves rated highest for relatability and effectiveness at conveying disease importance.

CONCLUSIONS

Participants supported the proposed use of industry-specific HAVS awareness posters in their workplaces. Future research should evaluate the effectiveness of these posters in the workplace.

Utility of electronic hand hygiene counting devices for measuring physicians' hand hygiene adherence applied to outpatient settings

BACKGROUND

Our objectives were to evaluate the utility of electronic hand hygiene counting devices in outpatient settings and the impact of results feedback on physicians' hand hygiene behaviors.

METHODS

We installed 130 electronic hand hygiene counting devices in our redesigned outpatient department. We remotely monitored physicians' hand hygiene practices during outpatient examinations and calculated the adherence rate as follows: number of hand hygiene counts divided by the number of outpatients examined multiplied by 100. Physician individual adherence rates were also classified into 4 categories.

RESULTS

Two hundred and eighty physicians from 28 clinical departments were monitored for 3 months. The overall hand hygiene adherence rate was 10.7% at baseline, which improved significantly after feedback to 18.2% in the third month. Of the clinical departments, 78.6% demonstrated significant improvement in hand hygiene compliance. The change in the percentage of physicians in each category before and after feedback were as follows: very low (84.3% to 72.1%), low (8.6% to 14.3%), moderate (2.9% to 8.9%), and high (4.3% to 4.6%), from the first to third month, respectively. Based on category assessment, 17.1% of physicians were classified as responders.

CONCLUSIONS

Physicians' adherence to hand hygiene practices during outpatient examinations was successfully monitored remotely using electronic counting devices. Audit and feedback of adherence data may have a positive impact on physicians' hand hygiene compliance.

Using medical student observers of infection prevention, hand hygiene, and injection safety in outpatient settings: A cross-sectional survey

BACKGROUND

Health care-associated infection outbreaks have occurred in outpatient settings due to lapses in infection prevention. However, little is known about the overall infection prevention status in outpatient environments.

METHODS

A cross-sectional design was employed to assess infection prevention policies and practices at 15 outpatient sites across New Mexico in 2014 during a medical student outpatient rotation. A standardized infection prevention checklist was completed via staff interview; observations of injection safety practices and hand hygiene behavior were conducted. Aggregate data were analyzed using Excel (Microsoft, Redmond, WA) and Stata (version 12.1, Stata Corp, College Station, TX) statistical software.

RESULTS

Medical practice staff interviews reported a mean of 92.8% (median, 96.7%; range, 75.0%-98.9%) presence of recommended policies and practices. One hundred sixty-three injection safety observations were performed that revealed medication vial rubber septums were disinfected with alcohol 78.4% (95% confidence interval [CI], 71.1%-84.7%) of the time before piercing. Three hundred thirty hand hygiene observations revealed 33.9% (95% CI, 28.8%-39.1%) use of alcohol-based handrub, 29.1% (95% CI, 24.2%-34.0%) use of soap and water, and 37.0% (95% CI, 31.8%-42.4%) use of no hand hygiene.

DISCUSSION AND CONCLUSION

These findings support the need for ongoing infection prevention quality improvement initiatives in outpatient settings and underscore the importance of assessing both self-report and observed behavior of infection prevention compliance.

Observation-based evaluation of hand hygiene practices and the effects of an intervention at a public hospital cafeteria

BACKGROUND

Hand hygiene is important before meals, especially in a hospital cafeteria where patrons may have had recent contact with infectious agents. Few interventions to improve hand hygiene have had measureable success. This study was designed to use a poster intervention to encourage hand hygiene among health care workers (HCWs) and hospital visitors (HVs) upon entry to a hospital cafeteria.

METHODS

Over a 5-week period, a poster intervention with an accessible hand sanitizer unit was deployed to improve hand hygiene in a hospital cafeteria. The dependent variable observed was hand hygiene attempts. Study phases included a baseline, intervention, and follow-up phase, with each consisting of 3 randomized days of observation for 3 hours during lunch.

RESULTS

During the 27 hours of observation, 5,551 participants were observed, and overall hand hygiene frequency was 4.79%. Hygiene attempts occurred more frequently by HCWs than HVs (P = .0008) and females than males (P = .0281). Hygiene attempts occurred more frequently after poster introduction than baseline (P = .0050), and this improvement was because of an increase in frequency of HV hand hygiene rather than HCW hand hygiene.

CONCLUSION

The poster intervention tool with easily accessible hand sanitizer can improve overall hand hygiene performance in a US hospital cafeteria.

Reactive arthritis developing after pneumococcal conjunctivitis: a case report

BACKGROUND

S. pneumoniae is a known cause of bacterial conjunctivitis and can be transmitted through contact with infected carriers.

CASE PRESENTATION

A 38-year-old ophthalmologist developing reactive arthritis following clinic-acquired pneumococcal conjunctivitis.

CONCLUSION

(1) Despite the frequency and largely self-limiting nature of infective conjunctivitis, it should be appropriately assessed and managed, as the natural history can occasionally be associated with significant morbidity. (2) Hygienic measures are required to be implemented by both patients and ophthalmic staff to reduce the likelihood of transmission.

Évaluation des pratiques professionnelles en matière de gestion du risque infectieux au cabinet d’ophtalmologie en région Bourgogne

OBJECTIVES

To evaluate the hygiene practices during ophthalmologists'consultations in Burgundy, France, so as to identify the difficulties they encounter in implementing new professional guidelines.

METHOD

The survey was based on an anonymous transversal descriptive survey conducted via a questionnaire sent in May 2006 to 102 ophthalmologists.

RESULTS

Data from 51 questionnaires were included in the survey, showing a good response rate (50%). The survey revealed that the perception of the risk of transmitting an infection was "important" to "most important" (59.2%). A steam autoclave was used by 38.8% of the ophthalmologists. Those who did not sterilize instruments disinfected them (30%). Finally, ophthalmologists preferred more information to training (90% versus 50%, p=0.015).

CONCLUSION

This survey highlights the need for improvements in education for practitioners and their assistants, especially in the sterilization of instruments and equipment.
