2 What are PQIs? IntroMedI - class 9 - PQIs

3 QIs Not definitive measures Use hospital discharge inpatient data Based on readily available data IntroMedI - class 9 - PQIs

4 PQIs Primary Healthcare Ambulatory Care Sensitive Conditions “avoidable hospitalization rates are a sensitive indicator for assessing quality of primary ambulatory care” ( Niti et al, 2003) IntroMedI - class 9 - PQIs Prevention starts here.

6 When were they first introduced? IntroMedI - class 9 - PQIs

7 Studies of the kind in other countries United States (Starfied et al.,1991, Sanderson et al., 2000, Kozak et al., 2001) Australia (Ansari et al., 2003, 2006) New Zealand (Sheerin et al., 2006) Canada (Roos et al., 2005, Porter et al., 2007) Singapore (Niti & Ng, 2003) Spain (Sánchez et al., 2004) Italy (Rizza et al., 2007) IntroMedI - class 9 - PQIs

12 RESEARCH QUESTION What is the status of the primary health care system in Portugal and how does it compare to past years and among its regions? IntroMedI - class 9 - PQIs

13 AIMS Assessment of the primary healthcare system quality, in an outpatient setting. Compare different level 2 NUTS*, trends Lay hypotheses for the observed differences. *except for Azores and Madeira. IntroMedI - class 9 - PQIs

14 IntroMedII - class 9 - PQIs Participants and Methods

15 PARTICIPANTS patients’ discharge data from national database (ACSS) 94 Acute Care Public Hospitals (continent) IntroMedI - class 9 - PQIs

16 DATA COLLECTION Data collected from acute care hospital database Variables of interest present in the database or calculated from others INE (Instituto Nacional de Estatística) provides populational and other statistical data IntroMedI - class 9 - PQIs

17 Division in NUTS II IntroMedI - class 9 - PQIs

18 INCLUSION Diagnosis according to PQI EXCLUSION Age <18 MDC = 14 or 15 Transferred from Related non-evaluative conditions IntroMedI - class 9 - PQIs

21 MDC Major Diagnostic Categories (MDC) Formed by dividing all possible principal diagnoses (from ICD-9-CM) into 25 mutually exclusive diagnosis areas.

55 IntroMedII - class 9 - PQIs Spain

56 IntroMedII - class 9 - PQIs Socioeconomic factors: gender age Income Propensity to seek care according to perceived health needs Hospital bed availability Regular source of care or continuity of care Differences in healthcare service (Public/Private healthcare; Insurances) Coding Issues Lack in Epidemiological Studies (or inconsistent) Intra-regional variations Study Limitations

57 IntroMedII - class 9 - PQIs Conclusions From 55 years old on: There is a clear increase in avoidable hospitalizations Males present higher avoidable hospitalizations rates Differences among years are not significant Norte presents the best quality/cost ratio Portugal shows a more efficient primary healthcare system than USA or Spain. Some heterogeneity among regions points to uneven primary healthcare supply Further study is required to evaluate yearly trends and precise factors which influence PQ.
