“…This would potentially overestimate the prevalence of medication users. However, primary non-compliance is considered small (18), and furthermore, prescription medication in the Greenlandic healthcare system is free of charge and delivered directly at the healthcare clinic.…”

ObjectiveThe aim of this study was to estimate the prevalent use of drugs targeting obstructive lung diseases among adults aged 50 or above in Greenland and to assess the use of spirometry testing among these medication users.Study designObservational cross-sectional study based on reviews of electronic medical records.MethodsThe study was performed in the 6 largest primary healthcare clinics in Greenland, representing approximately 67.0% of the population in Greenland. Adults aged 50 years or above, who had at least one electronically prescribed drug targeting obstructive lung diseases within a 15-month time interval, were identified. We assessed whether a spirometry test was registered in their medical records within previous 2- and 4-year periods.ResultsA total of 565 persons were identified. This corresponds to a prevalent medication use of 6.1% (565/9,023) among adults aged 50 years or above. Among these medication users, 14.1% (80/565) had a spirometry test performed within 2 years. Within the 4-year period this increased to 17.9% (101/565).ConclusionThe use of medication targeting obstructive lung diseases in Greenland among adults aged 50 years or above is common. However, spirometry testing among medication users is low and interventions aiming to increase focus on spirometry testing should be integrated in the primary healthcare system.

“…The prescription database is complete for all redeemed prescriptions, thereby including all medication for obstructive lung disease, but patients who do not redeem prescribed medication will be misclassified in the register and therefore not be included in the cohort. However, we consider that this misclassification is insignificant as primary non-compliance is considered small [23]. All spirometry measures given in primary and secondary health care are assessed through two large administrative registries and an underreporting to these registers would lead to an underestimation of spirometry testing.…”

Influence of socioeconomic and demographic status on spirometry testing in patients initiating medication targeting obstructive lung disease: a population-based cohort study

et al. 2013

BackgroundSocioeconomic status is known to influence the prevalence, severity and mortality of obstructive lung diseases, but it is uncertain whether it affects the use of diagnostic spirometry in patients initiating treatment for these conditions. The objective of this paper was to examine a possible association between education, income, labour market affiliation, cohabitation status and having spirometry performed when initiating medication targeting obstructive pulmonary disease.MethodsWe conducted a population-based cohort study. Danish national registers were linked, retrieving data on prescriptions, spirometry testing, socioeconomic and demographic variables in all first time users of medication targeting obstructive lung disease in 2008.ResultsA total of 37,734 persons were included and approximately half of the cohort had spirometry performed. Among medication users under 65 years of age, being unemployed was significantly associated with reduced odds of having spirometry performed, the strongest association was seen in men (OR = 0.82, CI = 0.73-0.91). Medium income was associated with increased odds of having spirometry performed in men (OR = 1.18, CI = 1.06-1.30) and high educational level (>12 years) was associated with reduced odds of having spirometry performed in women (OR = 0.86, CI = 0.78-0.94). Cohabitation status was not associated with having spirometry performed. Among medication users over 65 years of age, living alone was associated with reduced odds of having spirometry performed among men (OR = 0.78, CI = 0.69-0.88).ConclusionSocial inequity in spirometry testing among patients initiating medication targeting obstructive lung disease was confirmed in this study. Increased focus on spirometry testing among elderly men living alone, among the unemployed and among women with higher education is required when initiating medication.

Does uncollected medication reduce the validity of pharmacy dispensing data?

Abstract: Primary non-compliance due to not claiming medication has little impact on the validity of pharmacy dispensing data in the region under study.
