1. THE PROSPECTIVE VERSION OF THE
APPROPRIATENESS EVALUATION
PROTOCOL (AEP) IN PORTUGAL:
OUR FIRST EXPERIENCE
Javier R. Vera, Nuno Vieira, Luisa Arez, Rui Tomé
Department of Internal Medicine. Sector I.
Hospital do Barlavento Algarvio
Portimão. Portugal. EU
2. INTRODUCTION
Appropriateness Evaluation Protocol (AEP).
-Developed on the ´80s to evaluate the overuse of
hospital beds.
-60 objective criteria. Classify as appropriate or
inappropriate the admission and stay.
-Appropriateness=1 criterion
3. Modalities of AEP (I)
Depending on the kind of Dependending on the
study: speciality:
-Prospective -Medical Protocol
-Concurrent -Surgical Protocol
-Retrospective -Pediatric Protocol
4. Modalities of AEP (II)
Complemented AEP :
1. Demographic parameters (age, gender)
2. Clinical parameters (multiadmission,
mortality, comorbidity-Charlson)
3. Appropriateness AEP
4. Management parameters: Average stay,
admission during the weekend, length of time from the
admission to the Emergency Department until the
admission to the Department of Internal Medicine
5. APROPRIATENESS EVALUATION PROTOCOL
Utility
• Numeric data.
Makes possible comparing the efficiency of hospitals
with similar characteristics.
B) Causes of appropriateness/inappropriateness.
Strategies to decrease inappropriateness
7. MATERIAL AND METHOD (I)
Kind of study:
Systematic randomized prospective study
Inclusion criterion:
Patients admitted on beds 9, 22, 23, 24 of Sector I
of the Department of Medicine during 2003.
Exclusion criterion:
Patients moved from other beds of the Department.
8. MATERIAL AND METHOD (II)
Tool of assessment:
Prospective medical complemented version of the AEP:
1. Demographic parameters (age, gender)
2. Clinical parameters (multiadmssion, mortality,
comorbidity-Charlson)
3. Appropriateness AEP
4. Management data: average stay, admission
during the weekend, time from the admission to
the emergency department to the admission to
the Department of Internal Medicine

16. CONCLUSIONS (I)
1.The inappropriateness of the admissions was 17,7%,
result similar to those of other studies carried out in
the Iberian Peninsula.
2. The most common criterion for appropriateness was
utilization of intravenous therapy. A careful
consideration of the need of parenteral medication
might eventually make the patients tributary of other
level of care than an acute care Hospital.
17. CONCLUSIONS (II)
3. The longer stay of the people admitted during the
weekend might be due to the inexistence of elective
medical care during that period. A specific program of
assistance to the ward on weekends might improve
this parameter.
