Leading the shop floor - Unsolicited advices!

Night shifts tire out A&E doctors and lead to considerable amount of distress. Things can go worse due to lack of staffing, complicated patients (who always turn up during these hours), unfamiliar (or familiar) locum doctors around. Explicit details vary depending on the "local settings and culture of Emergency Medicine" but overall theme remains the same to manage a busy department overnight. By morning, we end up signing countless ECGs, ordering several medications (with minimal background info available) and listening to numerous SHO/F2 case presentations. Essentially, we walk on the very thin ice during night shifts and there are good chances of making errors. 

Is there a way to circumvent this or at least minimize this risk?
What can we do to manage flow better and avoid handing over an 8 hour waiting time?


1. Using checklists
  • Procedural Sedation Checklist
  • Resuscitation checklist 
  • Post Cardiac Arrest Care checklist
  • Reading a CXR checklist
  • ECG checklist 
  • Discharge Checklist



These can reduce cognitive overloading, save time and minimize errors, especially during the busy hours.

2. Listening to FY/SHOs presentations 
Take time and set rapport with your night team. Get a sense of their background, previous experiences and what rotations they have been through so far. Allocate tasks keeping this in your mind. Early on, try and see (at least eyeball) every patient that they are allocated and once you understand their clinical acumen, go with that. 




Being approachable with junior doctors is they key for patient safety. Ask them if they are concerned about anything in particular or if they want you to examine the patient. 

3. Documentation and Risk Management 
Diagnostic uncertainty is a part of Emergency Medicine. it is almost impossible to come with a definite diagnosis within a span of few hours. Sometimes, it takes weeks and months to reach a definitive diagnosis after several out-patient visits. Our job is to think about life threats. We work on the basis of probability and likelihood. Explain this to a patient. Most of them will appreciate and just need some reassurance. Prepared scripts can be useful here. For instance, discharging a low-risk chest pain. Document a clinical decision rule such as HEART score and tell them that:


Based on our evaluation today, your blood reports, and serial ECGs, your risk of heart disease is extremely low. I think your symptoms are likely due to acid reflux. I am going to prescribe some medications and discharge you. With aging, we all develop some degree of blockage in blood vessels around the heart and you may have that as well but this does not mean that you are having a heart attack. You need to follow up with you General Practitioner as an out-patient for further evaluation, see response to reflux medications and a for a definite diagnosis. However, if things change anytime i.e you feel unwell, sweaty, dizzy, short of breath or concerned about anything else then please come back to A&E and we will be happy to assess you again. We are here 24x7. 

Document this conversation briefly in the chart briefly under "Medical Decision Making". Your chart should depict your thought process and rationale behind your decisions. Use scoring systems like Wells, PERC, HEART to manage risk. Occasionally, you will see a patient who asks for a 100% definite diagnosis. Ask about their concerns and set expectations as soon as you see them. If you are sending someone home who looks clinically very well but with a unclear diagnosis, safety net them and arrange further follow up as an out-patient. 



Documentation: It is best to finish documentation/clerking as you go rather than carrying a bunch of charts with you to finish after the morning handover. After the handover, you would want to leave the ED ASAP and this will certainly compromise the quality of your notes. Write explicit and legible notes. 

Patient info leaflets and discharge advice: If you think they are going home, hand over specific discharge leaflets to them beforehand. Tell them to have a glance through them and ask any questions. This keeps them busy and helps to understand their ailment better. Moreover, you are medicolegally safer since you hand over written red fags to them specifying when to return to ED.

4. Triage led blood sets (for minors) - to expedite decision making
  • Young Chest Pain 
  • Pleuritic Chest Pain 
  • CP with risk factors
  • Abdo pain female
  • Abdo pain male 
  • Shortness of Breath 
  • Needle Stick Injury
  • Febrile Illness
  • Fever in Traveller 

Triage led to blood tests based on chief complaints improves the flow but these should be interpreted carefully. Sending troponins for every 20yo with CP will lead to nowhere and may lead to unnecessary further testing. I advocate that tests such as d-dimer and hs-troponin should only be ordered after discussion with a consultant or any senior physician whenever possible. Both these tests are very non-specific but if used judiciously, they can be very useful. Routine second troponins lead to unnecessary long waits and prolong the length of stay. False positive d-dimers subject patients to the unnecessary risk of anticoagulation and follow up. 

Avoid "just to be sure" type of investigations. Do not start hunting for problems in a well-looking 90-year-old. Follow guidelines for imaging and deviate only if you feel strongly about something. If a blood test is not going to alter your management, then don't do it. Check out RCEM guidelines on redundant activities here. 


5. Situational Awareness and communication
While running the show as a registrar (equivalent to final year resident in the US), do less and allocate more. Having a good sense of what is going around with patients seen by junior doctors is crucial. Anticipate further care needs of every patient. For instance, eyeballing patients on arrival and organizing imaging such as X Rays and Head Scans can save a lot of time. Ask yourself:
  • What can you do for this patient in ED?
  • Who is well and who is sick? 
  • Who needs admission and who can be discharged?
Seasoned clinicians almost always decide to admit v/s discharge after 2-3 minute conversation with a patient, occasionally just after eyeballing a patient! Verbalise a clear plan to junior doctors and if possible, write it on the chart. 

Keep a track of co-morbidities and social issues (carers, living alone, frail elderly demented, homeless, domestic violence) before discharging patients. Think twice before discharging an elderly during twilight hours. On a 10 hour shift, I typically spend just about 1 hour with patients and rest of my time goes in getting things done - requesting scans, discussion with Radiology and inpatient teams, adding blood tests, calling labs, difficult cannulas, and most-importantly documentation. When running the shop floor, it is important to delegate as much as you can. 
  • IV Cannulation - Ask the nursing staff to keep the USG machine and equipment ready
  • Joint reduction - Ask FY/SHO to prep everything - hook them to monitor and keep sedation drugs ready 
  • FAST/AAA Scan - Move the patient to a room and keep the USG machine jelled  
  • Wound Repair - Procedure nurse to prepare equipment 
If you are leading the department, then your time is precious. Everyone will be out there looking for you (nurses, junior docs, angry patients, in-patient teams, difficult referrals) and don't involve yourself in something time-taking procedures. 

I work in an enormous ED and it can take me up to 2 minutes to walk from one end to the other. Having a list of phone numbers of HDU, Minors, Resus, Assessment areas can be immensely useful. You can then just call and liaise with nurses rather than physically going to each of these areas. 



Communicate with nurses : Nurses are the backbone of your team and if they stand by your side, things go very smooth. Know them by their names and let them know that you are running the shop floor before you begin your shift. Assign them tasks like putting back slabs, getting medications quickly, patients who need monitoring and frequent observations. 

6. Calling for help
Knowing our limitations is crucial and we must know what we exactly want a specialist to do when we call for a consult. Whether it is ITU, Anesthetics, Trauma team - the theme remains the same. Whenever possible, know their names and with time set a rapport with them. Developing negotiation skills while conversing with a specialist is a skill that we all must learn. 


7. Safeguarding and other clerical work 
On a busy shift, the last thing we want is a doctor held up in sorting out safeguarding and social issues for a patient. Undoubtedly, these tasks are important our job should be to raise concerns about them. FIlling 6 page long referral forms and sending e-mails to a group of people can be very time-consuming and this can seriously halt the flow of the department. I strongly believe that these tasks would be best done by a clerk (non-medical) as this does not require a medical degree. 


If you have anymore thoughts on this, then please feel free to comment and share your wisdom.

Constant Jet Lag in Emergency Medicine

Emergency Medicine is high risk speciality that brings a lot of stress with it and maximum burn out rates among its providers. A major reason why people quit EM is due to the rotating shifts. And as we turn older, it gets difficult to cope up with this ever changing shift work schedule. Many of us suffer from this under appreciated problem of shift work disorder. Rather than accepting Shift Work Disorder (SWD) as something that always comes along with EM, we should find out ways and learn how to cope up with it. 


What is Shift Work Disorder?
SWD is clinically recognized condition that develops in some individuals who work at night, start work early in the morning (4am-7am), or work according to a rotating shift schedule. SWD consists of a constant or recurrent pattern of sleep interruption that results in difficulty sleeping when you should sleep or excessive sleepiness when you are supposed to stay awake and alert. 

Problems that might occur with Shift workers:
Medical errors 
Disturbed circadian rhythm
Risk of peptic ulcer disease
Cardiovascular disease
Hypertension
Chronic Fatigue, insomnia
High Divorce rate
Substance abuse and Depression
Immunosuppression
Fertility issues
Poor dietary choices
Thyroid issues
Most circadian rhythms have both an endogenous component (regulated by suprachiasmatic nucleus of the hypothalamus) and an exogenous component. The exogenous component is composed of various time clues called zeitgebers. One of the most powerful zeitgebers is the light/dark cycle (e.g. Sun). Other examples of zeitgebers can be food, television, exercise, caffeine, sports. We can synchronise with these zeitgebers and give the right cues to our body to promote wakefulness/sleep. 

For instance , prior to starting a night shift, exercising OR eating typical breakfast foods OR exposure to bright light gives subtle clues to your body that it is time to get up and start the day. Similarly, having a cup of coffee, bright light exposure and exercising after a night shift is a bad idea!!


Few Strategies for setting up night shifts:
1. If you can work it out, then the best way is to do a stretch of nights for 6-8 weeks once in a year. This way you would need to change your sleep cycle only twice a year (not every week!). No meetings/academic sessions after night shifts.

2. Casino Shifts: With casino shifts, one long night shift is cut into two short shifts, from 10pm-4am and from 4am to 10am. With these shifts the "early risers" turn up for the 4am shift and people who prefer to sleep late in the night leave by 4am. Both these groups can then continue their next day normally without affecting their social liv. Some people like and prefer to work like this.


3. Avoid doing >2-3 nights in a row.

Shift Length: Some physicians prefer shorter shifts (6-8hrs) and some like to stick to the 12hr shifts. With shorter shifts, it is found that physicians are more alert and respond better while with the two 12hr shifts, you get more days off per week. 


Here are some things that we can do to cope up with Shift work:

1. Education and Awareness (For shift workers as well as their families)

2. Individual Strategies

Prior to night shift, To promote wakefullness:
  • Make sure you get some sleep during the day time (Never start a night shift in sleep deprivation)
  • Exercise in the evening 
  • Expose yourself to bright light 
  • Having more staff overnight is beneficial
  • Have dedicated breaks, with coffee and high protein foods
During night shift, To stay alert 
  • Keep your naps short (<30 minutes)
  • Stay exposed to bright light
  • Have a high carbohydrate/protein snack to keep you awake
  • Caffeine (only during the first half of shift)

After night shift, To promote sleep:
  • Use sunglasses while travelling back home to avoid bright light exposure
  • Use ear plugs/eye protectors, black curtains 
  • Make sure that your room temperature is comfortable 
  • Keep your kids and pets away to avoid disturbances while you are asleep (Noisy environments cause sleep fragmentation)
  • Have a dedicated quiet area to sleep
  • Avoid fatty/ spicy food before you sleep
  • Avoid early morning caffeine 
  • Switch off your phone and try using an answering machine


Shift schedule should be made by someone who understands SWD


ACEP endorses the following principles:
  • Scheduling isolated night shifts or relatively long sequences of night shifts is recommended. 
  • Overly long shifts or inordinately long stretches of shifts on consecutive days should be avoided whenever possible. In most settings, shifts should last twelve hours or less. Schedulers should take into consideration the total number of hours worked by each practitioner and the intervals of time off between shifts. 
  • ACEP strongly recommends that practitioners have regularly scheduled periods of at least 24 hours off work. 
  • Rotating shifts in a clockwise manner (day to evening to night) is preferred.
  • Night shift workers' schedules must be designed carefully to provide for anchor sleep periods, and those workers' daytime responsibilities should be held to an absolute minimum. 
  • Groups should consider various incentives to compensate those working predominantly night shifts. 
  • Schedules for emergency physicians should take into account factors such as ED volume, patient acuity levels, non-clinical responsibilities, and individual physician's age. 
  • A place to sleep before driving home after night shifts should be provided.


3. Pharmacolgy

To promote sleep:
BZDs (addiction, side effects)
Zolpidem is better than BZDs
Melatonin: take few hours prior to sleep, dose: 0.5-5mg

Stimulants to promote wakefullness:
Modafinil (Dopamine reuptake inhibitor, Also activates Glutamate and inhibits GABA)
Caffeine: Too much leads to agitation, tolerance overtime and withdrawal. Avoid taking caffeine during the second half of your shift.
Energy drinks: Caffeine + sugar 



Key Points
  • Educate your family and colleagues about Shift Work Disorder
  • Learn how to play with the zeitgebers
  • Do not overly on medications
  • Consider incentives for those who work the unpopular night shifts
