1 1 The effect of drug co-payment policy on the purchase of prescription drugs for children with infections in the community Haim Reuveni, MD Health Policy 62 (2002) 1–13 Department of Health Policy and Management, Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel First Study

2 2 Introduction Co-payment (CP) policy - patients cover part of treatment cost CP policy reduces expenditures of the insurance carrier and unnecessary use of services CP reduce consumption of the medical care, prescribed drugs mainly among low SES people CP cause deterioration in health state. Each 10% increase in CP is associated with an 8.7% decrease in total per-episode expenditure

3 3 Aims To examine the effect CP on the purchase of prescribe drugs in children with acute infectious diseases. This was preformed in community settings (Pediatric Health Center in the city of Kiryat-Gat)

4 4 Objectives 1.To calculate the rates of partial or non-purchase of antibiotics (WHO classification). 2.To assess the association between the number & cost of prescribe drugs and the non or partial purchase of the drugs. 3.To identify factors that can predict non or partial purchase of prescribe drugs due to cost considerations.

5 5 Methods Design: Cross-sectional study. Setting: The Pediatric Health Center in the city of Kiryat-Gat one of Israel’s poorest cities (high unemployment rate). The pediatric clinic has: a registry of 6500 children an average of 200 visits per day. 5 pediatricians. Data collection was for 6-weeks in May to June 1999.

6 6 Study population Included: Children and adolescents aged 0–18 years, diagnosed by a pediatrician with an acute infectious disease for which drugs, including antibiotics, were prescribed. Excluded: children and adolescents that: (1) already taking antibiotic drugs (2) diagnosed for an acute infectious disease, but did not receive a prescription (3) received a prescription which did not include antibiotics.

7 7 Data sources 1)The computerized patient visit reports (I.e. demographics, type of drug, dosage, date of prescription). 2) The computerized drug dispensing reports from the clinic’s pharmacy.

8 8 Three study groups were defined: Full purchase- All drugs prescribed were issued by the pharmacy. Partial purchase- Some of the drugs and/or amounts were issued. Non-purchase- None of the prescribed drugs were issued within 7 days of prescription date.

14 14 Conclusions: CP is a serious barrier for purchasing the prescribed medication for children with acute infections. The policy has a particularly deleterious effect in under-privileged populations. CP policy is in contradiction with the proclaimed principles of justice and equality underlying the obligatory Israeli National Health Insurance Law.

15 15 The incomplete purchase (partial treatment) of antibiotics may: lead to an extended period of symptoms. Development of long-term complications such as meningitis and rheumatic fever. The role of partial antibiotic treatment in the development of antibiotic resistance is not clear.

16 16 More questions……. What are the drug purchasing patterns when several family members are concurrently ill. What is the long-term clinical outcome for these children? What is the consequent extent of medical care utilization by these children? How can we define a “reasonable level ” of CP ? for essential drugs or other treatments…….. Zero CP? for different layers of income……….. Partial/Full CP? Further studies are required……….

A/147/2003. 3 d Study

22 22 Introduction CPAP device is provided free of charge in countries such as Germany, the United Kingdom, several parts of Canada and by some health care providers in the USA. In these countries, treatment initiation and long-term compliance were found to be more than 70%. In Israel, results strongly suggest that sharing the cost of CPAP is a potential barrier to purchase CPAP.

23 23 Main Objective To develop a model for decision-makers to determine CP policy for CPAP

24 24 Specifically 1) To compare compliance rates according to CP policy with that of other industrialized countries 2) To determine the cost-effectiveness of CPAP therapy. 3) To compare compliance rate to CPAP before (full CP) and after change (partial CP) in CP policy.

25 25 Group 1- Declining CPAP. 1a- CPAP will be re- offered CPAP with partial CP. 1b- CPAP will not re-offered Group 2- Commencing CPAP. Group 3- New patients, minimal CP. followed-up for 12 m
