Introduction
Recording clinical information is important to the health industry
Access to previous information leads to better diagnosis and treatment in the future [Movig KL, Leufkens HG, Lenderink AW, Egberts AC. Validity of hospital discharge International Classification of Diseases (ICD) codes for identifying patients with hyponatremia. J Clin Epidemiol. 2003 Jun;56(6):530-5.]
Paper-based record / Electronic records
Paper Based vs Electronic Based Clinical Records
Lacks of information of previous studies [Movig KL, Leufkens HG, Lenderink AW, Egberts AC. Validity of hospital discharge International Classification of Diseases (ICD) codes for identifying patients with hyponatremia. J Clin Epidemiol. 2003 Jun;56(6):530-5.]
Electronic patient record (EPR) as the main method in a near future.[Gillies J, Holt A. Anxious about electronic health records? No need to be. N Z Med J. 2003 Sep 26;116(1182):U604.]
It is important to study and to conclude if this new information organization will result in any difference from the old one.
Paper Based vs Electronic Based Clinical Records
Advantages and disadvantages of EPR and paper-based records. Most of the studies conclude that the electronic system is better, although some of them disagree.

Paper Based vs Electronic Based Clinical Records
Objective
The main objective is:
Quantify the differences among diagnosis and procedures recorded before and after the EPR implementation in the paper-based and the electronic-based methods.
Paper Based vs Electronic Based Clinical Records
Methods
Participants and Methods
Type of study: it is longitudinal and observational
We chose two departments to work about (obstetrics and pneumology) and two periods of time (a few months before and after the implementation of EPR)
We treated two databases on SPSS®, each from one of the departments
Each database was divided in two periods, before and after the implementation
Paper Based vs Electronic Based Clinical Records
Inclusion criteria
We made a selection of the main diagnosis on each department: On the obstetrics department we chose those with a
minimum number of 20 cases on the sum of both periods On the pneumology department we chose those with a
minimum number of 10 cases on the sum of both periods
We did two kinds of analyses: a qualitative one and a quantitative one.
Paper Based vs Electronic Based Clinical Records
Methods – 1st PeriodFirst Period
Each DRG code consists on a general code that groups together several diagnoses into one variable
Each database was divided in two periods: Before and After EPR
Qualitative Analysis The qualitative analysis consists on checking the differences
between the GDH before and after the introduction of EPR
By using a statistical test (Chi-square) on SPSS® we have searched for significant differences between GDH from the two groups previously selected
After analyzing the differences in a major perspective we decided to check each GDH individually to quantify the differences by using another Chi-square test.
Paper Based vs Electronic Based Clinical Records
Quantitative Analysis
(it focuses on the number of the diagnosis rather than the type of diagnosis)
We started working with all the diagnosis instead of using only GDH in order to compare the number of diagnosis before and after the implementation
The main test used in this case was a Mann-Whitney test
Paper Based vs Electronic Based Clinical Records
Methods – 2nd Period
Paper Based vs Electronic Based Clinical Records
Second Period
The database used in the first period was changed into one that allowed us to check the frequency of each diagnosis/procedure separately.
The diagnosis/procedures selected were the fifteen with more cases on the sum of the before and after periods.
Using SPSS® the information was analised in two differente ways: General Approach to the data including the 15 diagnosis/procedures,
using a chi-square test. Each diagnosis/procedure was checked for differences between the
two periods of time, using chi-square tests.
Both doctors and coders from both departments were enquired in search for justification for the statistically significant differences found

Diagnosis: “Parto Vaginal sem complicações” (GDH373)
In a first phase we searched for general differences in the GDH.Secondly we searched for differences on each individual GDH. This is an example of a GDH where we found statistically significant differences. The other cases are: “Cesariana sem complicações” (GDH371); and “Laqueação de trompas via laparoscópia” (GDH362).

The 1-sample K-S test confirmed that it wasn’t a normal distribution as
p<0,01 , so it is <0,05.
As it wasn’t a normal distribution we had to do a non-parametric
test for two independent variables.As we can see p=0,861 which is >0,05, so we accept nule
hypothesis.

the increase of the registration of this procedures contradicts the increase of the diagnose 664.01 (Laceração do perínio do primeiro grau). We found no explanation for this fact.
it increased because it became indispensable in every case of non tranquilizer fetal state.
Large increase of cases. There are two possible reasons: more available devices; and the existence of a phd theses in course, related to the decrease of the cesarians by non tranquilizer fetal state.
The decrease of this three procedures are the result of an intentional reduction of the registration of this kind of methods, because they are a kind of procedure that is done in almost every treatment and it not necessary neither useful to keep this type of information.

The increase of this diagnoses is related to the management of the distribution of the patients between departments. The patients were usually randomly distributed between the internal medicine and the pneumology departments. But recently, the pneumology department is taking care of the delicated cases, like the ones above, which justifies the difference found.
