6. Time gap between from incorporation and clinical protocol publication (months) |
Discrete variable (Count) |
Description |
Analyzes the influence of PCDT in diffusion rates, due to definition of prescription and utilization criteria. |
Method |
Identification of the publication date of PCDT. If the PCDT was published prior to the medication incorporation, the variable value was zero. |
7. Treatment for infectious diseases |
Binary variable (Yes, No) |
Description |
Analyzes the influence of type of disease in diffusion rates of pharmaceutical innovations, considering that infectious diseases have limited time for treatment in comparison to other types of diseases. |
Method |
Assessment of characteristics of the targeted diseases, according to description in PCDT. |
8. Lag period after incorporation of the medicine (in trimesters) |
Discrete variable (Count) |
Description |
Information used to estimate the diffusion rates over time (up to three years after incorporation). |
Method |
Assignment of ordinal category corresponding to the number of trimesters after incorporation. |
9. Area of specialty in medicine |
Binary variable for each area of medical specialty (Cardiology, Hematology, Infectious Disease, Rheumatology, Gastroenterology, Nephrology, Neurology) |
Description |
Analyzes the influence of the area of medical specialty of the disease on diffusion rates of pharmaceutical innovations. |
Method |
Analysis of the PCDT for the targeted disease, in order to determine the area of medical specialty for treatment of the disease. Each disease was categorized in only one specialist area, if more than one area was indicated; the most representative specialist area was adopted. |
10. Medicine with patent (monopoly) |
Binary variable (Yes, No) |
Description |
Analyzes the influence of the presence or absence of generic or similar drugs at the moment of incorporation, which presupposes the absence or presence of patent, respectively. |
Method |
Search in the price list of the Chamber for Regulation of the Pharmaceutical Market, in order to identify generic or similar drugs in Brazil. |
11. Annual cost of drug therapy per patient |
Continuous variable (Log R$) |
Description |
Analyzes the interference of drug therapy costs per patient in the diffusion rate and potential impacts of reduction in prices due to scale in production, considering that overall budget impact may influence the access to medication within the SUS. |
Method |
Estimation of annual costs for standard treatment (in log), considering recommended dosage of the medication in the PCDT for the targeted disease, at the period of pharmaceutical innovation incorporation within the SUS. A standard patient profile weighting 70kg was adopted, in case of dosage per body weight. The annual costs were based on the amount of medication for annual treatment and the PMC (18%) from the Chamber for Regulation of the Pharmaceutical Market (2014). |
12. Higher price in comparison to pharmaceutical competitors |
Binary variable (Yes, No, NA) |
Description |
Analyzes the influence of variations in price on the diffusion rate, in comparison with other technologies for drug therapy of the same disease already available at the SUS. |
Method |
Comparison of the variable "annual cost of drug therapy per patient" in relation to the annual costs estimated for drug therapy of the targeted disease using other medication available within SUS. The annual costs were based on the amount of medication for annual treatment and the PMC (18%) from the Chamber for Regulation of the Pharmaceutical Market (2014). If there are no other therapeutic options for treatment of the disease, the variable value was "non applicable". |

Description |
Assesses the impact of diverse patterns of acquisition of medication for CEAF (federal, and/or state level acquisition) on diffusion rates. |
Method |
Identification of the public management level responsible for acquisition of the medication, through search in Ministry of Health ordinances that established the Component of Medications with Exceptional Dispensation (Ordinance GM/MS 2,577/2006), the CEAF (Ordinance GM/MS 2,981/2009), and other ordinances published for alteration or revocation of the previous ordinances and its annexes.
