How data influences decision-making in the health care industry
John is diagnosed with stage III colon cancer and is informed of several treatment options by his doctor. As John is not medically-trained, he does not have the medical knowledge or knowledge of new trends in treatment to decide what treatment option is the best for his specific circumstances (family history of colon cancer, 55 years of age, diabetic patient), or to decide if he needs a second opinion on treatment options. How can data help John to make an informed decision on which treatment option to select?
Pharmaceutical company A has a new treatment for colon cancer, drug X, which they want to launch. They also want to apply for funding from the medical schemes for this drug. How can data help pharmaceutical company A to show to the medical schemes that drug X is a cost-effective option compared to the current standard of care, and that drug X should, therefore, be funded by the medical schemes? Further to this, how can data help pharmaceutical company A to know in which regions to place the bulk of their sales representatives?
Pharmaceutical company B has launched a new treatment, drug Y, and wants to broaden the indication and simultaneously broaden access to patients on a lower option medical scheme. In conjunction with this, they want to show that the drug is safe and effective in real-world practice. How can data help pharmaceutical company B to reach these objectives?
Many diverse data sets are created in the health care industry. These include patient-reported outcomes, patient registries, medical schemes claims data, clinical trial data, sales data, and more.
How can this data be used to assist John and pharmaceutical companies A and B to make informed decisions?
Firstly, the outcomes that can be extracted from health care data should be considered.
Outcomes that can be extracted from health care data
A diverse set of outcomes can be extracted from health care data:
- From patient-reported outcomes: The subjective level of joint pain experienced because of, for instance, rheumatoid arthritis, measured via a scale such as the visual analogue scale (VAS).
- From patient registries: The efficacy of a drug for treating a specific patient population could be determined, considering specific patient characteristics, such as age, gender, whether the patient has diabetes, as in Johnâ€™s case, etc.
- From medical schemes claims data: Patient journeys, for instance, the in-hospital cost of treating a patient with colon cancer. Further to this, what specific areas of costs contribute most to in-hospital cost (for instance, ICU vs general ward vs medicine cost), for patients treated with drug X compared to patients treated with drug Y?
- From clinical trial data: The efficacy of one drug compared to another to treat a disease. This data can further be used, in conjunction with cost data and safety (adverse event) data, to ascertain whether a specific drug, such as drug X, is cost-effective, compared to another drug.
- From sales data: The total number of units of a drug sold per year, and factors influencing sales, such as seasonality and the location and effort of sales staff.
Methods used to extract outcomes from health care data
A variety of methods are used to extract outcomes from health care data:
- From medical schemes claims data and patient-reported outcomes: Descriptive and inferential statistical analysis using tools such as Microsoft Excel or SAS.
- From patient registries: Big data analysis methods using statistical modelling and machine learning, such as descriptive, predictive and prescriptive analytics.
- From clinical trial data: A pharmacoeconomic model can be developed that uses the efficacy data, together with cost data from amongst others medical schemes claims data, to determine whether a drug or device is cost-effective, compared to a comparable drug or device (comparator). Methods used in modelling can include Markov modelling (where a disease or treatment of a disease is broken into different states, with different utilities/weights and costs related to each state), as well as newer techniques such as discrete event simulation. Further to this, clinical trial data can be analysed using biostatistics, to prove efficacy in terms of predefined primary and secondary endpoints.
- From sales data: Depending on the size of the data set, different methods can be used, including big data analysis methods.
How can value be extracted for the patient and pharmaceutical or device company?
Methods one to three above can be used to inform John of the best drug to use for his specific circumstances, considering both the cost and efficacy of the drug and considering his age, diabetes status and family history of colon cancer (personalised medicine).
For pharmaceutical company A, methods one to four can help to provide evidence to the medical schemes of the cost-effectiveness of drug X, and to determine where to best place different sales staff members to achieve the optimal number of sales in a specific region.
For pharmaceutical company B, methods one, two and four can help to provide evidence to broaden the indication or access for lower option scheme members. These methods can also be used to prove efficacy and safety in a real-world setting, compared to a clinical trial setting.
These examples demonstrate how value can be extracted for the patient, the pharmaceutical (or device) companies as well as the medical schemes companies. However, the scientific evidence by itself is insufficient to convince them of the value of the drug. It requires a subtle combination of science, art and communication to convert these abstract concepts into value stories that will inspire them. By combining science with art, one can communicate the value of products and/or treatments in a language that appeals to each of these stakeholders.
