Background To evaluate the effectiveness of a brief mindfulness intervention on hand hygiene performance and mindful attention for inpatient physician teams.
Design A pilot, pre-test/post-test randomised controlled mixed methods trial.
Setting One academic medical centre in the USA.
Participants Four internal medicine physician teams consisting of one attending, one resident, two to three interns and up to four medical students.
Intervention A facilitated, group-based educational discussion on how mindfulness, as practised through mindful hand hygiene, may improve clinical care and practices in the hospital setting.
Main outcomes and measures The primary outcome was hand hygiene adherence (percentage) for each patient encounter. Other outcomes were observable mindful moments and mindful attention, measured using the Mindfulness Attention Awareness Scale, from baseline to post-intervention, and qualitative evaluation of the intervention.
Results For attending physicians, hand hygiene adherence increased 14.1% in the intervention group compared with a decrease of 5.7% in the controls (P=0.035). For residents, the comparable figures were 24.7% (intervention) versus 0.2% (control) (P=0.064). For interns, adherence increased 10.0% with the intervention versus 4.2% in the controls (P=0.007). For medical students, adherence improved more in the control group (4.7% intervention vs 7.7% controls; P=0.003). An increase in mindfulness behaviours was observed for the intervention group (3.7%) versus controls (0.9%) (P=0.021). Self-reported mindful attention did not change (P=0.865).
Conclusions A brief, education-based mindfulness intervention improved hand hygiene in attending physicians and residents, but not in medical students. The intervention was well-received, increased mindfulness practice, and appears to be a feasible way to introduce mindfulness in the clinical setting. Future work instructing clinicians in mindfulness to improve hand hygiene may prove valuable.

Hand hygiene is broadly accepted as an integral component for preventing infection in hospitalised patients.1 Unfortunately, healthcare provider adherence to hand hygiene practices is relatively low, even when education programmes for hand hygiene are well resourced and well coordinated.2–4 Of note, hand hygiene adherence is known to be lower among physicians than nurses,5–7 and before patient encounters relative to after.2 7 Although a myriad of strategies, including education, feedback and incentives have been implemented to encourage hand hygiene, most have had only transient or modest impact.8 Therefore, innovative strategies are needed to improve hand hygiene among healthcare providers.9
The practice of mindfulness is described as paying attention in the present moment, in a purposeful and non-judgemental way.10 Mindfulness is meant to help move a person from a state where thoughts are unobserved and actions are on automatic pilot, to a state where situations are observed, acknowledged and accepted. A recent systematic review found that brief mindfulness interventions aimed at healthcare providers improve myriad clinical outcomes.11 Teaching healthcare providers informal practices, such as mindful hand hygiene, could similarly bring mindfulness into clinical practice. Further, the role modelling of mindful hand hygiene within a clinical setting may have a cascading effect on others. This group effect could lead to collective mindfulness,12 where the behaviour of peers affects others to improve hand hygiene rates of others.7 9 Adoption of mindful practice, in turn, may have other benefits including enhanced attention,13 situational awareness,14 provider well-being10 and reduction of diagnostic medical errors by addressing cognitive biases.15
We sought to assess if mindful hand hygiene would promote hand hygiene adherence and mindful attention among physicians and medical students in a hospital setting. We selected physicians in particular for hand hygiene compliance among physicians lags behind that of most other professional groups.6 Using a pilot, randomised controlled mixed methods trial, we examined the effectiveness of a brief, mindfulness educational session on hand hygiene adherence and mindful attention for inpatient physician teams. This proof of concept intervention sought to understand whether physicians were receptive to mindfulness as a means to improve hand hygiene. We hypothesised that participants exposed to mindfulness would exhibit increased hand hygiene and mindfulness behaviours compared with those randomised to the control group.
Study design, setting and participants
We designed a pre-test/post-test randomised controlled mixed methods trial at a tertiary care health system. Participants were attending physicians, residents, interns and medical students, who were recruited and enrolled by a research coordinator from inpatient, internal medicine teaching teams in February and March 2016. Morning rounds on the medical wards were selected as they are a key part of daily clinical care where most medical decisions are made. Rounds are also a time when senior physicians role-model group norms, set expectations and outline best practices to physicians in training.16 All team members provided written informed consent to be part of the 2-week study.
Baseline rates of hand hygiene before and after patient room entry for each member of the team on the medicine wards were collected using a standardised, secret shopper auditing approach.17 Five observers with previous experience observing hand hygiene adherence (three research specialists, two students) received training regarding the established recommendations for hand hygiene auditing (ie, type of hand hygiene performed, on entry and exit of patient room and when to document ‘unknown’) (online supplement 1).18 Additional training was provided regarding the observation of mindfulness behaviours, which were identified in two ways: first, if a person paused from walking, talking or engaging with their environment and appeared to focus on the process of rubbing soap/gel into hands and, second, when a person was noted to take multiple, slow, deliberate breaths while performing hand hygiene.10 Observers were instructed to document ‘unknown’ if they were unable to observe or unsure that they witnessed mindful behaviour. Baseline observations occurred for 5 weekdays, during morning rounds (2–4 hours), on acute care medicine units. No new hand hygiene programmes were being introduced in the organisation during this time frame.

To measure self-reported mindfulness before and after the intervention, all participants completed the Mindfulness Attention Awareness Scale (MAAS) at baseline. The MAAS13 is a validated 15-item scale that focuses on the self-regulation of attention aspect of mindfulness. The MAAS was selected over other mindfulness measures19 due to the brevity of the scale13 and prior use with healthcare providers.20–23 The MAAS survey items ask respondents to indicate the frequency with which they experience various behaviours related to mindfulness, ranging from 1 (almost always) to 6 (almost never). Higher scores reflect higher levels of mindful attention.
Following baseline evaluation, an independent statistician allocated teaching teams to either the intervention or control group in a concealed fashion using an allocation ratio of 1:1 derived from SAS, v 9.3. Each team contained eight participants (ie, one attending, one resident, two to three interns, three to four medical students). Hand hygiene observers were blinded to allocation. Following randomisation, the teams were observed for hand hygiene adherence and mindfulness behaviours for another 5 weekdays during morning rounds (2–4 hours/day). At the completion of the second period of observations, both teams were invited to retake the MAAS survey and provide feedback on the intervention through individual interviews and focus groups.
The intervention consisted of two components: first, a brief 10 minute informational video entitled, ‘All it Takes is 10 Mindful Minutes’ by mindfulness expert Andy Puddicombe, was shown.24 Following the video presentation, the primary investigator (VC) led a 60 min guided discussion on how he uses principles of mindfulness to generate reflective pauses while providing clinical care. The primary investigator shared personal anecdotes and clinical examples of instances where stopping to be aware of his physical and emotional state influenced decision-making, patient care and outcomes. Because it is difficult to find moments to practise mindfulness during busy clinical days, hand hygiene was offered as a prompt to pause, take a few deep breaths and attend to the flow of thoughts in one’s mind before entering a patient’s room. During this pause, a moment to reflect, crystallise thoughts and visualise what may happen in the encounter while acknowledging and accepting internal emotions or feelings was suggested. Participants were given a guide for a moment of mindfulness during hand hygiene (online supplement 2).9 The discussion then turned to the group who shared their experiences and asked questions about integrating this into their clinical practice. The control group did not receive the brief mindfulness education session and continued with usual care.
The primary study outcome was hand hygiene adherence (yes/no) as blindly observed from an independent observer for each encounter with a patient. Other outcomes of interest were observable mindful moments as recorded by the independent observer for each patient encounter and MAAS scores from baseline to postintervention.
Differences in baseline hand hygiene adherence, mindfulness behaviours and MAAS scores between intervention and control groups were assessed using Fisher’s exact test and t-test, as appropriate. Risk differences in adherence to hand hygiene from baseline to postintervention were calculated for both intervention and control groups. Similarly, risk differences from baseline to postintervention were computed for mindfulness behaviour, stratified by intervention/control group. Because the primary outcome (ie, hand hygiene) occurred frequently, we used generalised linear models to evaluate pre-post changes in hand hygiene adherence for the intervention versus control group, with the Poisson distribution (log link) and robust error variance, incorporating clustering by teaching team.25 Statistical significance was calculated for the interaction term for time (pre-post) and intervention (intervention vs control), stratified by physician type. A similar approach was used to assess mindfulness behaviour. For MAAS scores, a generalised linear model was used with a normal distribution and an identity link, with an interaction term to assess time*intervention, clustered by teaching team. All statistical tests were two sided, with P<0.05 considered statistically significant. All analyses were conducted using Stata V.14 (StataCorp, College Station, TX).
Qualitative evaluation of the intervention
To enhance our understanding of mindfulness, hand hygiene practices and the MAAS survey results,26 we conducted focus groups and interviews with those randomised to the intervention in accordance with published recommendations.27 28 Focus groups were performed using a semistructured guide (online supplement 3) that aimed to understand how residents, interns and medical students perceived the intervention and their lived experience of practising mindfulness during hand hygiene. Similarly, we conducted separate, in-person, one-on-one interviews with attending physicians to understand their experiences and perceptions. Focus groups and interviews were recorded and transcribed. Two qualitative researchers (MQ, SW) independently reviewed the transcripts and conducted a descriptive content analysis. Researchers used a list of preliminary deductive codes to identify and develop additional inductive codes that further explained the data. Differences in coding were resolved through discussion and key themes and quotes from the focus groups and interviews were synthesised to explicate findings.
Participant flow in the study is presented in figure 1. Five physician teams were approached; one team declined to participate owing to high patient volumes. The remaining four physician teams were randomised to two groups (intervention and control). Each team included eight participants. All participants were observed for hand hygiene and mindful behaviours during patient encounters, yielding a total of 1299 unique hand hygiene observations. For the secondary outcome using the MAAS instrument, four participants randomised to the intervention group did not attend morning rounds when postintervention surveys were completed, and one participant in the control group did not complete all questions on the MAAS, yielding a final sample of 27 participants for this outcome. A total of six physicians and four medical students participated in the focus groups and interviews following the intervention. Due to the pilot nature of this study, demographic data for the teams (eg, gender, age) were not collected.
At the end of the first week of baseline observations, hand hygiene adherence rates for the intervention and control groups were 72% and 85% (P<0.001), respectively. At baseline, mindfulness behaviour during hand hygiene was observed once (<1% of all observations) for the intervention group and once (<1%) for the control group (P=0.89). No significant difference in baseline mean MAAS scores between the intervention and control groups was observed (4.21 (SD=0.70) vs 3.86 (SD=0.64), respectively,P=0.18). Both groups reported moderately high MAAS scores, similar to results for healthy community dwelling adults (4.20).13
Primary outcome: hand hygiene adherence
Hand hygiene adherence increased 14.1% from baseline to post-intervention for attending physicians who received the intervention, but decreased by 5.7% in the control group (P=0.035). Similarly, interns who received the intervention increased hand hygiene adherence by 10.0% from baseline to postintervention compared with a 4.2% increase for interns in the control group, a statistically significant difference (P=0.007). Residents who received the intervention demonstrated the greatest absolute improvement in hand hygiene practice with a 24.7% increase, while residents in the control group saw no improvement in adherence (0.2%) (P=0.064). Medical students in both the intervention and control groups increased hand hygiene adherence (4.7% vs 7.7%, respectively). However, the increase was greater among the controls (P=0.003) (table 1).
Observed mindfulness behaviours and MAAS results
A 3.7% increase in observed mindfulness behaviours during hand hygiene was recorded for members of the intervention group and a 0.9% increase was observed for members of the control group (P=0.021) (table 1). Despite the significant increase in observed mindfulness behaviours with the intervention, no significant changes in MAAS mean scores from baseline to postintervention were noted for intervention (−0.15; 95% CI −0.46 to 0.76) or control groups (−0.14; 95% CI −0.40 to 0.68; P=0.865).
Focus groups and interviews
A total of two focus groups comprising members of two different teaching teams (n=8-residents, interns and medical students) and two interviews (n=2- attending physicians) were conducted. Key themes related to physician perceptions of mindfulness, how physicians linked hand hygiene to mindfulness and recommendations for future implementation were identified. No harms or unintended effects were reported by participants.
Physician perceptions of mindfulness
In general, all participants were favourable to the idea of the practice of mindfulness in clinical settings. The overwhelming sense was that practising mindfulness could result in improved physician well-being and consequently, improved doctor–patient relationships.
…Anything that allows a healthcare provider to just be more present, I don’t know how to say it without sounding hyper corny, but like more emotionally available and open, I think contributes to a much better provider–patient relationship. (Attending)
When you survey physicians…the stress levels are just so high. So, to me, mindfulness is a way to help people be happy with what they’re doing…and then you hope that filters into their interactions with patients. (Attending)
Feedback on mindfulness educational session
Overall, participants reported positive feedback for the content and length of the educational session.
I thought it was great. I thought some of the positives were that it was relatively brief, which I think is good because unfortunately logistics are always something we have to think about in the clinical day and I thought it was great to be able to get the entire team there to sort of have it at the same time and experience the same thing and it allowed some people to share thoughts on the topic. (Attending)
I thought the length of it was appropriate. It didn’t seem too long to incorporate on a busy day. I liked the mix of trying to include personal interaction and then the video. I think if we had just watched the video, it would have felt kind of flat but…the personal remarks added a lot. (Resident)
Experiences linking hand hygiene and mindfulness during the intervention
When asked, seven of the 10 participants said they began to practise mindfulness during hand hygiene following the intervention, indicating feasibility of the practice. Although a moment of hand hygiene for mindfulness was appreciated, maintaining consistency in the practice proved challenging.
I liked the hand hygiene thing. I thought it was just interesting. I never thought about that as an opportunity to be mindful so it was…one moment that we all experience multiple times a day that we just take a second to think. (Student)
I mean it crossed my mind the first couple of days after the session but usually there were three other people behind me and I thought it would be a little strange to just sit there pausing and thinking while everybody waited to go in the patient room. (Intern)
I think the challenge is to remember to do it…with all the other things going on, that’s just something that’s easily forgotten and takes a backseat to a lot of the other things that you end up doing. (Intern)
Recommendations for increasing mindfulness during hand hygiene
Several participants offered suggestions to improve mindfulness and hand hygiene during clinical practice.
Attendings are kind of responsible for setting the pace of rounds and so if the attending stands outside the room and finishes washing his or her hands with the sanitizer, the rest of the team may actually pause there with him or her to do that. (Resident)
I think before rounds is a better time, like when the whole team is there, either on the floor or in the team room, would be a good time to have a moment of mindfulness. (Intern)
In this pilot randomised controlled study, we found that a brief, education-based mindfulness intervention using hand hygiene was feasible to instruct physicians and medical students on mindfulness in the clinical setting. The intervention appeared to improve hand hygiene rates in physicians, particularly among attendings and interns. Hygiene rates for medical students increased in both intervention and control groups. There was a significant increase in observed and self-reported mindfulness behaviours during hand hygiene in the intervention group, but no significant difference in the MAAS scale. Qualitative feedback from participants suggested that while they attempted to improve mindfulness behaviours, integrating the practice into clinical rounds was challenging. However, because the physicians and medical students embraced mindfulness within a hand hygiene-based intervention, future work linking mindfulness to hand hygiene practice may prove valuable.
Our study adds to an existing body of literature investigating how mindfulness practice can be a resource for healthcare providers. Two recent publications have proposed mindfulness practice for clinicians as a strategy to increase metacognition and reduce the effects of biases that are associated with diagnostic and other medical errors.15 29 In a review of empirical studies of traditional, 8-week mindfulness-based stress reduction (MBSR) programmes for healthcare providers, the evidence suggested that participation in MBSR yields physical and mental health benefits for providers.30 In a systematic review, brief mindfulness interventions modified to fit the schedules of providers positively influenced levels of stress, anxiety, mindfulness, resiliency and burnout symptoms in hospital-based nurses and physicians.11 Collectively, these studies suggest that mindfulness practice can impact a variety of attributes that could influence patient safety. However, few studies have focused on identifying key factors such as the dose of mindfulness practice required to provide long-term benefits for providers and patients.11 30
Why use hand hygiene as a moment to integrate mindfulness into clinical practice? First, hand hygiene is an activity performed multiple times throughout the day and thus provides defined moments for pause and practice. The data gleaned from participant interviews suggest that physicians are looking for an oasis in time to concentrate and reflect in the midst of patient care. Second, because hand hygiene occurs immediately before and after patient interaction, it was embraced by physicians and medical students in our study as an opportune time to become present and practise self-care. Additionally, collective mindfulness, such that the behaviour of attendings influenced others, was also viewed as a benefit of this approach during morning rounds. However, providers also noted that it was challenging to perform mindful hand hygiene at this time due to competing demands. Similarly, concerns about social stigma when practising mindfulness is a reality that will require leadership and role modelling by attendings and residents to offset. The suggestion to briefly practise as a group prior to rounds has been previously studied with inpatient nurses21 and resident physicians.31 The approach was reported to be relatively easy to implement and well received by participants; however, the influence on provider and patient outcomes requires further study.
We found no significant change in MAAS scores despite improvement in observed and self-reported mindfulness behaviours. Absence of such findings may relate to the small sample size of this study, compounded by missing data from several participants who did not complete the postintervention survey assessment. Alternatively, the brief nature of mindful hand hygiene practice introduced in this study may not have been a large enough dose to alter MAAS scores, especially in participants with an inherent predisposition to mindfulness.11 Lastly, the relative insensitivity of the scale to small changes in mindful attention may also explain lack of improvement in mindful attention.
Limitations and strengths
Our study has several limitations. First, our study was a proof of concept study conducted at a single centre with a brief observation period and limited follow-up. Multicentre studies that are larger in scale and address the sustainability of the intervention are needed. Second, our study targeted physicians and medical students; whether mindfulness would be effective with nurses and other health professionals is unknown. However, nursing theory32 describes hand hygiene as a self-care practice, suggesting that nurses may be an ideal group to shape organisational and cultural norms and propagate mindful hand hygiene. Third, our study only focused on the effect of mindful practice on hand hygiene during rounds. The impact on hand hygiene moments during other times of the day (or night) is not known. However, team rounds are an integral aspect of clinical care and often include nurses, pharmacists and patients. Thus, making it an ideal time to role-model mindful practice.
Our study was also performed in an academic setting where baseline hand hygiene adherence was high. Whether similar findings will be generalisable to other healthcare settings involving different patient and provider populations is unclear. Further, hand hygiene adherence was measured using covert observations. Though an industry standard, hand hygiene practice is reported to increase when clinicians are aware of auditor activity.17 Relatedly, the external observation of a mindful moment is subjective and may have unblinded the intervention group to auditors. Validation of a mindful moment through objective measurement (eg, devices that measure breathing rate) may prove interesting for future research.
The intervention was 60 minutes in length and included open discussion among peers, perhaps limiting generalisability and scalability to other settings. Finally, although the exact mechanism for the increase in hand hygiene is unclear, the evaluative feedback from physicians exposed to the intervention was encouraging. The reported influence of seeing a senior physician practise mindful hand hygiene suggests the group effect may be an underlying mechanism, as previously suggested in the literature.7 33 34 Though this may not translate to times when individual physicians see patients outside of rounds or in non-academic settings, mindfulness practise through hand hygiene appears feasible and acceptable to attendings, residents, interns and medical students.
Our study also has strengths. First, this was a methodologically rigorous study that used a randomised design with concealed allocation in a real-world setting. Outcomes were recorded by trained observers who were blinded to assignment. Additionally, we used qualitative and observational evaluative techniques to supplement the quantitative data. Due to the known challenges of measuring and observing the construct of mindfulness,26 the use of a mixed methods approach provides insight into how participants viewed the intervention and may have used it in practice. Future studies that focus on the enhancement of well-being,26 the impact on patient safety15 and the positive effect on others26 of mindful hand hygiene thus appear possible. Third, we found that healthcare providers uniformly appreciated the opportunity to pause and reflect before engaging in patient care. Given rising concerns about provider burnout and well-being, our study suggests that mindfulness may be an option in building physician resilience.
A brief mindfulness-based intervention introduced mindfulness in the clinical setting and improved physician hand hygiene rates. Though the exact mechanism for the improvement in hand hygiene is unclear, the intervention was well received by participating medical teams and resulted in self-reported and observed increases in mindfulness practice. Larger trials that test the intervention in diverse settings are needed to determine whether mindful hand hygiene can increase clinician mindfulness, improve hand hygiene practice, influence provider well-being and ultimately enhance patient safety.
