Why don’t people get admitted for investigations here?

My father in law is 68 and was a previously healthy and fit man.

Over the past 2 months he’s developed a chronic, moderate to severe cough, extreme fatigue and weakness, loss of appetite and a weight loss of 25 pounds. A short walk from his kitchen to his front door causes him to need to sit down as it tires him.

He was sent for lab work and his WBC, Neutrophils, Creatinine, and total PSA are high.

His RBC, Hemoglobin, Hematocrit, eGFR are low.

His urine returned positive for Leukocytes and blood but the culture returned negative.

His chest x ray showed a dark/cloudy spot at the base of one lung. Doctors have said it isn’t cancer but they don’t know what it is. No other testing was done. That assumption is based on imaging.

Throughout all of this they’ve put him on 4 different antibiotics hoping one has him feeling better. None have made a change and he continues to worsen.

He’s been sent to a respirologist who can’t see him for another month.

He’s had a CT scan ordered which isn’t until May.

All of this seems a bit off to me with his blood work results and symptoms.

Where I’m from in Europe he’d likely get admitted right away and doctors would work to figure out what’s causing the symptoms.

There doesn’t seem to be any urgency here and it’s quite concerning.
