For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
3. Strategic descisions
How can the access policy for scheduled patients be divided?
- Pre-scheduled patients, scheduled in advance of the appointment day
- Same-day (open-acces) patients, scheduled for the same day
3. Strategic descisions
What are the 5 access policy, explain
Everything is booked in advance
2. Open access
All capabilities to same-day appointments
3. Hybrid
Combination traditional and open access
4. Carve out
Reserves a certain amount of capacity for specific procedures
5. Same-day or next-day policies
Books today's patients on the day they call or the next day
3. Strategic descisions
What is a downside of the traditional access policy?
3. Strategic decisions
What are barriers for the open access?
3. Strategic decisions
Why accept walk-ins?
3. Strategic decisions
What do you do?
- Walk in rate < 20%
- WAlk in rate > 20%
admitting
>20%
admit when:
number of patients waiting + expected number of punctual
pre-scheduled patients < total capacity of the remaining slots
3. Strategic decisions
When is the best time to leave slots open for urgent patients?
3. Strategic decisions
What do seasonal walk-ins (weekly or monthly) show?
3. Strategic decisions
What are is meant with offline and online schedules?
Appointments are scheduled after all requests have arrived
Online
Patients are scheduled immediately upon arrival
Importance offline planning is growing
What are 7 tactical decisions for outpatient clinics?
2. Appointment intervals
3. Appointment scheduling window
4. Block size
5. Number of appointments per consultation schedule
6. Panel size
7. Priority of patients groups
4. Tactical decisions
Why do shorter appointment slots perform better?
4. Tactical decisions
What do you do when:
- standard deviation unpunctuality increases
- mean of patient unpunctuality increases
Reduce interval size
Mean of patient unpunctuality increases
Increase the interval length slightly
4. Tactical decisions
What does an appointment scheduling window do?
4. Tactical decisions
What happens when there is a reduction in the scheduling window?
> Decrease no-show rate
> more efficient clinic
Downside: overly restrictive reduces the number of patients seen so reduction revenue.
3. Strategic decisions
What is the best performing access policy, and what is the best realisation of this access policy
Modification ratio of same-day and pre-scheduled + overbooking mitigates the impacts of no-shows and outperforms the rest
No period or two period hybrid policy makes no difference.
4. Tactical decisions
What do the following rules do:
- baileys rule
- individual block rule
- multiple block rule
- variable block rule
2 patients in the first block, 1 patient in the other blocks leave the last block empty
individual block rule
1 patient in all blocks
multiple block rule
fixed batch of patients in all slots
Variable block rule
Variable batch size
4. Tactical decisions
What does the multiple block rule and variable block rule mitigate?
But when too large, patient waiting and system overtime increase.
4. Tactical decisions
What is an approximately optimal policy for the number of appointments per consultation session?
4. Tactical decisions
What is calling population?
Consequently, panel size can be larger than service capacity
4. Tactical decisions
What happens when the panel size is too large?
- Indirect waiting times increases > increased no shows
- Level of continuity of care decreases
4. Tactical decisions
What are [2] type of priorities of patients, explain
Patient priorities must be met at all times applied upon patient arrivals (emergency)
Soft
Patient priorities are not applied upon arrival assigning a different weight reflecting relatively importance
What are [6] operational descisions?
2. Appointment day
3. Appointment time
4. Patient acceptance/rejection
5. Patient selection waiting list
6. Patient sequence
5. Operational descisions
What are [2] approaches?
Easy to implement heuristic, no guarantee of performance
OBA Optimization-Based Approach
Specifying optimal level for an operational decision with guarantee of performance, global optimal solution
5. Operational decisions
What are [2] important factors to be considered in the allocation of patients to servers/resources?
- Continuity of care
- patient preference physician
5. Operational decisions
What are [2] types of appointment time schedule?
- Predetermined appointment slots
- No predetermined slots, patients are scheduled anytime in the consultation session
5. Operational decisions
Based on what [3] things are patients selected from the waiting list?
- Capacity allocated to each patient group
- Patient waiting time
- Patient priority level
5. Operational decisions
What is a good rule in the determination of the patient sequence?
Order patients in increasing variance
6. Environmental factors
What are:
- non-preemptive interruptions
- preemptive interruptions
Between consultations
Preeptive interruptions
During consultaiton
6. Environmental factors
What are [2] type of preemptive interruptions, explain
The treatment procedure repeats from the beginning independently of the earlier service
Preemptive resume
Service resumes from the place it was interrupted
6. Environmental factors
What are:
- Single appointments
- Combination of appointments
- Appointment series
Combination of appointments
Multiple appointments one patient scheduled in one day
Appointment series
Multiple appointments on more than one day
7. Modelling approaches
What is single-stage stochastic programming
7. Modelling approaches
What is a two stage stochastic programming
- Descision variables are appointment times
- Variables are auxiliary variables
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
