3C Applications of health services information Flashcards
Healthcare evaluation: formative Vs summative evaluations
FORMATIVE: Evaluations can be conducted whilst an intervention is ongoing/ being developed in order to inform ongoing intervention
SUMMATIVE: evaluation is conducted at the end of the intervention or evaluation of an established intervention/programme
Use of data for healthcare planning: how can data help with planning services, what 3 stages are needed
- ASSESS NEED
- requires an epidemiological, qualitative and comparative approach. Need to consider need and future need (population forecasts) - DEFINE PRIORITIES determine priorities based on the most effect use of resources
- HEALTHCARE REVIEW define current services and how these compare to those that will be needed to identify services which are deficient and those which are superfluous
Use of data for performance management: what are performance management useful for
- performance management indicators are used to identify how services are performing against a dimension agreed to be important for that service
- they are particularly useful in identifying when services are inadequate or there are problems with service delivery
- if problems are identified further evaluation is needed
Use of data for healthcare evaluation: describe broad structures of healthcare evaluation frame works
- healthcare evaluation often considers metrics covered by donabedians framework (structure, process, outcome)
- cost and impact are almost always considered
- quality should also be considered ie maxwells 6 dimensions effectiveness, efficiency, equity, Acceptability, Access, Revelance
What is an information system?
- an information system is a process in which raw information is transformed (usually by a computer) into meaningful information that can be used
What is an information system specification?
- an information system specification is the set of requirements agreed between the user and developer of the system
- development requires a high level of user engagement
Give 6 examples of information system uses
SEAL CAC
- SECURITY
- information systems can ensure data is not lost or corrupted - EXCHANGE
- information systems can enable secure exchange of information - ANALYSIS
- information systems can analyse, display and report data - LINKAGE
- information systems can link information from multiple data sources - CLINICAL INFORMATION
- information systems can ensure a clinicians can access all relevant patient information ie bloods, xrays, notes - AGGREGATION
- information systems can aggregate data so that health care can be evaluated and monitored - CLINICAL GUIDELINES
-information systems can ensure clinicians can access appropriate clinical guidelines
measures of health care provision: give examples of primary care measures
- Number of GPs per 1000 population
- Average distance to nearest health centre
- Practice list size per GP
- waiting time for a GP appointment
measures of health care provision: give examples of secondary care measures
- number of consultants per 100000 population
- number of beds per 100000 population
- average distance to nearest hospital
- wait list time for elective surgery
measures of healthcare usage: what factors affect health care usage
Healthcare suage is a complex relationship between:
- Need
- Provision
- access
measures of healthcare usage: Primary care
- average number of consultations per patient
- number of secondary care referrals
-average time spent with practitioner - number of prescriptions per patient
- uptake of screening services
- uptake of vaccination
Measures of healthcare usage: secondary care
- emergency hospital admissions
- number of outpatient appointments
- bed occupancy
- length of stay
Mathematical modelling: what is mathematical modelling
The process of analysing and simplifying a complex real-world problem/ situation using maths
The process enables observations to be analysed, using statistical or other techniques, so they can be used to predict events or provide solutions
Mathematical modelling: Advantages of mathematical modelling
used properly mathematical modelling can:
- support decision making process
- deal with complexity
-create alternative scenarios
- model an issue
- create short, medium and long term plans
Mathematical modelling: Uses if mathematical modelling in healthcare
- model costs/benefits of different interventions as part of an economic evaluation
- depict different possible outcomes and their probabilities in order to aid decision making (clinical and mathematical)
- model communicable disease outbreaks
- predict future trends in disease
- predictive risk modelling (analyses the probability of an outcome depending on the presence of dependent variables)
Mathematical modelling: limitations of mathematical modelling
The usefulness of a model may be constrained by:
- the availability of data
- the quality of data
- the appropriateness of the assumptions made in the model
- use of inappropriate or flawed techniques
