ESTABLISHING HEALTH INTERVENTION PRIORITIES FOR LOCAL PUBLIC HEALTH AGENCIES Alexandre Klementiev Tacoma-Pierce County Health Department, WA

GOAL 2 “To identify three broad-based, behavioral risks to health which, if reduced, will offer a tangible reduction in the burden of preventable illness and death in the Pierce County population *.” j * Tacoma - Pierce County Health Department Strategic Plan, (Tacoma, WA)

This presentation demonstrates the method designed for identification of the leading behavioral risks to health. If these risks were reduced, the method would allow to estimate the resulting reduction in the burden of preventable illness and death. GOAL 2 (contd)

RISK FACTOR If a disease/cause of death (D) is more common among those with a certain characteristic (C) than among those without it, then there is an association between C and D. If C occurs, or is present, prior to D, the characteristic C is a risk factor for the disease (cause of death) D.

C is present C is not present D D D D D D D D D

BURDEN OF HEALTH RISK The burden of a health risk is composed of: l Disabled years lived with preventable illnesses (morbidity component) l Deaths associated with specific risk behaviors (mortality component)

FROM ROUTINELY COLLECTED HEALTH DATA TO MILLER’S INDEX In 1970, J.E.Miller offered the Q-index which allows integrating of morbidity and mortality data, so that a fairly consistent ranking of the classes of disease could be made.

Q-INDEX: DEFINITION Q k = (MT k /MR k )*P k *D k + 100,000*A k /365 /N + 100,000*B k /(3*365)/N

Q-INDEX: DEFINITION (contd) MT k (MR k ) : age-/sex- adjusted mortality rate in target (reference) population; P k : years of life lost due to premature death, average per one death ; D k : crude mortality rate; A k : number of inpatient days, per year; B k : number of outpatient visits, per year; N : size of the target population. ___________________________________________________________________________________________________________________________ k indicates disease/cause of death.

Q-INDEX: DISCUSSION  Q-index provides a rationale for combining mortality and morbidity components in a single index number which is used for ranking  This rank pertains to a given class of disease/cause of death  In reality, the risk factor is associated with more than one class of disease/cause of death

FROM Q-INDEX TO THE RISK PRIORITY INDEX The Q-index cannot be used for prioritizing health programs when those programs pertain to the behavioral health risks associated with multiple classes of diseases

RISK PRIORITY INDEX: DEFINITION The Risk Priority Index (RPI) is defined as the sum of all partial impacts of the health risk of interest on the population health. Partial impacts of diseases and deaths in RPI are measured with the use of the Q-index.

CALCULATING RPI  The method of calculating the RPI components depends on the availability of relevant data  The direct method is based upon data collected on relative risks and prevalence pertaining to the risk factor of interest, along with mortality, bed-days, and the outpatient visits  If some of the data for the direct method is unavailable, experts best estimate can be used for the lacking data

FROM THE RISK PRIORITY INDEX TO THE HEALTH INTERVENTION PRIORITY INDEX l The RPI cannot be used for establishing priorities of health interventions l The Health Intervention Priority Index accounts for the partial reduction of the health risks

HEALTH INTERVENTION PRIORITY INDEX: DEFINITION The Health Intervention Priority Index (HIPI) is the quantitative measure of improvement of the population health caused by implementation of the health intervention The improvement is measured in person-years of life saved

TOBACCO: HIPI It was assumed in this study that the relative reduction of smokers in Pierce County by 40% (from about 25% down to 15%) is an achievable goal. As a result: l 240 deaths would be prevented l 858 person-years of life would be saved

DIETARY FACTORS AND ACTIVITY PATTERNS: HIPI It was assumed in this study that relative reduction of the aggregated risk factor associated with dietary factors and activity patterns by 15% is an achievable goal. As a result: l 134 deaths would be prevented l 253 person-years of life would be saved

ALCOHOL: HIPI It was assumed in this study that the relative reduction of the aggregated risk factor associated with alcohol misuse by 20% is an achievable goal. As a result: l 55 deaths would be prevented l 775 person-years of life would be saved

FIREARMS: HIPI A 15% relative reduction of the aggregated risk factor associated with firearms was assumed in this study as an achievable goal. As a result: l 14 deaths would be prevented l 402 person-years of life would be saved

UNPROTECTED SEX: HIPI A 10% relative reduction of the aggregated risk factor associated with unprotected sex was assumed in this study as an achievable goal. As the result: l 5 deaths would be prevented l 160 person-years of life would be saved
