To investigate the use of specialized health care services for diverticular disease in different hospital referral regions in Norway.
Nationwide cross-sectional study with data from the Norwegian Patient Registry and Statistics Norway. All Norwegian inhabitants aged 40 years and older in the years 2012-16 (2,517,938) were included. We obtained the rates (n/100,000 population) for hospitalizations, outpatient appointments, and surgery for diverticular disease for the population in each hospital referral region. We also quantified the use of lower gastrointestinal (LGI) endoscopy in hospitalizations and outpatient appointments for diverticular disease and the use of LGI endoscopy performed on any indication.
There were 131 hospitalizations and 381 outpatient appointments for diverticular disease per 100,000 population annually. Hospitalization rates varied 1.9-fold across regions from 94 to 175. Outpatient appointment rates varied 2.5-fold across regions from 258 to 655. Outpatient appointments were strongly correlated to hospitalizations (rs=0.75, p?
To determine how long patients in Ontario waited for major breast, colorectal, lung or prostate cancer surgery in the years 1993-2000.
"Surgical waiting time" was defined as the interval from date of preoperative surgeon consult to date of hospital admission for surgery. We created patient cohorts by linking appropriate diagnosis and procedure codes from Canadian Institutes of Health Information data. Scrambled unique surgeon identifiers were obtained from Ontario Health Insurance Plan data. Changes in median surgical waiting times were assessed with univariate time-trend analyses and multilevel models. Models were controlled for year of surgery and other patient (age, gender, comorbid conditions, income level, area of residence) and hospital level characteristics (teaching status, procedure volume status).
Compared with 1993, median surgical waiting times in the year 2000 increased 36% for patients with breast cancer (to 19 d), 46% with colorectal (to 19 d), 36% with lung (to 34 d) and 4% with prostate cancer (to 83 d). Multilevel models confirmed significant increases in waiting times for all procedures. There were no concerning or consistent differences in waiting times among the categories of hospitals and patients examined.
There were significant increases in surgical waiting times among patients undergoing breast, colorectal, lung or prostate cancer surgery in Ontario over years 1993-2000. Administrative databases can be used to efficiently measure such waits.
