Primary and secondary outcome measures In-hospital mortality: the joint effect of comorbidity and age on the risk of
dying.
Results: A total of 689 patients (median age, 44 years) admitted with RT-PCR-confirmed COVID-19 were included in
the study. Of these, 77.36% of patients were discharged alive while 22.64% died. 11.61% required some kind of oxygen
support, while 2.8% of patients required intensive care unit admissions. Older age (HR 2.88, 95% CI 2.09 to 3.98),
presence of comorbidities (HR 2.56, 95% CI 1.84 to 3.55), history of hypertension (HR 3.19, 95% CI 1.67 to 6.08), and
presence of symptoms at the time of admission (HR 3.21, 95% CI 1.41 to 7.26) were associated with an increased risk
of in-hospital mortality. Treatment with a combination of azithromycin with hydroxychloroquine, antivirals, or steroids
compared with no treatment did not alter the disease course or in-hospital mortality. The combined effect of old age
and the presence of comorbid conditions was more pronounced in women than in men.
Conclusions: In-hospital patients were younger, less symptomatic, and less dependent on ventilators and oxygen
support as compared with many western countries.
Applied Project
You have been assigned the task of observing the behaviour of people working in the parking lot of a supermarket.
During the observation, you should keep an eye on the maximum number of people working at a time in the parking
space. How does the employee interact with the drivers of the vehicles coming into and going out of the parking
space? Do they provide any extra assistance to the customers? How well are they able to manage space so that they
can accommodate a maximum number of cars at peak shopping hours? You are free to add any observations that you
may find interesting.
