“…In the absence of a scoring algorithm for Norway, the Norwegian Medicines Agency recommends [ 8 ] use of the UK EQ-5D-3L value set [ 9 ] mapped to the EQ-5D-5L descriptions of health [ 10 ], a “crosswalk value set”. This crosswalk value set was used for the Norwegian EQ-5D-3L population norms [ 11 ] and is available to the system of national quality [ 31 , 32 ]. The questionnaire also included questions relating to age, gender, and education level.…”

Purpose To provide the first Norwegian EQ-5D-5L and EQ VAS population norms for the adult general population. Methods Postal survey of a random sample of 12,790 Norwegians identified through the National Registry of the Norwegian Tax Administration. Norms, weighted for Norwegian general population characteristics, are shown for the five EQ-5D-5L dimensions, EQ-5D index, and EQ VAS scores for seven age categories, females, males, and education level. Results There were 3200 (25.9%) respondents to 12,263 correctly addressed questionnaires. The EQ-5D-5L dimensions, EQ VAS, and background questions were completed by 3120 (24.6%) respondents. The mean age (SD) was 50.9 (21.7) and range was 18–97 years. The youngest age group of 18–29 years and oldest of 80 years and over had the highest (n = 691) and lowest (n = 239) number of respondents, respectively. Compared to the general population, the respondents comprised a greater number of females, younger and older ages, and had a higher education level. 32% of respondents reported no health problems on the EQ-5D-5L. From the youngest to oldest age groups, there was a general decline in health as assessed by the EQ-5D-5L. The exception was for anxiety/depression, where the youngest age groups had the poorest health. Apart from self-care, women reported poorer health than men, as assessed by the EQ-5D-5L; EQ VAS scores were similar for men and women. Higher levels of health (EQ-5D index, EQ VAS scores) were found with increasing levels of education. Conclusion The population norms will improve interpretation of EQ-5D-5L and EQ VAS scores in Norwegian applications including clinical practice, clinical and health services research, and national quality registers where EQ-5D-5L is the most widely used patient-reported instrument.

“…Specific codes varied more widely (Supplemental Tables 1 and 2). Twelve studies (35%) based their analysis on procedure codes without matching diagnosis codes, 26,29,35,36,41,44,45,47,49,[51][52][53][54] and fifteen studies (44%) based their analysis on matching both procedure codes and diagnosis codes. 25,28,37,[40][41][42]46,48,50,55,56 One study based the analysis on diagnosis codes.…”

“…50,52 Study Design Optimal for Quality Improvement Study characteristics important for quality improvement were described in Table 4. Regional variation in patient's outcomes was analyzed in 7 articles (21%), 24,26,28,31,35,43,48 of which 5 articles were published in the most recent years (2018-2020). Fourteen articles (41%) tried to identify variables that explain the variation in surgical rates.…”

Study Design Literature review. Objective To describe whether practice variation studies on surgery in patients with lumbar degenerative disc disease used adequate study methodology to identify unwarranted variation, and to inform quality improvement in clinical practice. Secondary aim was to describe whether variation changed over time. Methods Literature databases were searched up to May 4th, 2021. To define whether study design was appropriate to identify unwarranted variation, we extracted data on level of aggregation, study population, and case-mix correction. To define whether studies were appropriate to achieve quality improvement, data were extracted on outcomes, explanatory variables, description of scientific basis, and given recommendations. Spearman’s rho was used to determine the association between the Extreme Quotient (EQ) and year of publication. Results We identified 34 articles published between 1990 and 2020. Twenty-six articles (76%) defined the diagnosis. Prior surgery cases were excluded or adjusted for in 5 articles (15%). Twenty-three articles (68%) adjusted for case-mix. Variation in outcomes was analyzed in 7 articles (21%). Fourteen articles (41%) identified explanatory variables. Twenty-six articles (76%) described the evidence on effectiveness. Recommendations for clinical practice were given in 9 articles (26%). Extreme Quotients ranged between 1-fold and 15-fold variation and did not show a significant change over time (rho= −.33, P= .09). Conclusions Practice variation research on surgery in patients with degenerative disc disease showed important limitations to identify unwarranted variation and to achieve quality improvement by public reporting. Despite the availability of new evidence, we could not observe a significant decrease in variation over time.
